Diminutive/affectionate form for the name Anatole?
Hi everyone!
I'm looking for a dimunitive/affectionate form for the name Anatole which would be used in a French or French-speaking family (or by a French/French-speaking lover and/or close friend). If different diminutives exist and they have different conotations (like one is something that could be used by friends but another is too "fluffly" and would most likely only be used by a parent) please let me know that sort of information too.
I've tried to google this, but all I'm getting is other versions of the name (like alternate spellings, eg: Anatol, or from other languages, eg; Anatoliy, which is the Russian version of this name). But I'm interested specifically in a diminutive/affectionate form.
(Also, I don't know if this matters, but the time period the story is set in is early 1800s. It seems to me that there isn't a lot of difference between how diminutives function now versus how they functioned then, just language convention wise, but I'm not sure? I know with a few Russian names there are minor differences (eg: for the name Dmitri, the diminutive Mitya was most common at that time, whereas now Dima is more common), so I thought I would mention this. If you know of a difference in which diminutives were used then v now, I'd be interested in that information too.)
Thank you!

Council celebrates Botswana's ruling upholding Bushmen's right to water
Media Release
January 27, 2011
The Botswana Court of Appeal upheld the Kalahari Bushmen's right to water by quashing a 2010 decision that denied the Bushmen access to a borehole on their ancestral lands.
"This is a major win, it's the first test case of the right to water resolution at the United Nations," says Maude Barlow, Council of Canadians chairperson and former Senior Advisor on Water to the President of the UN General Assembly. The UN General Assembly and UN Human Rights Council passed resolutions last year recognizing the right to water and sanitation.
A Bushman spokesman said, 'We are very happy that our rights have finally been recognized. Like any human beings, we need water to live.'"
The Kalahari Bushmen have been embroiled in a 30-year battle for their right to ancestral lands and the right to water.
After diamonds were discovered in the late 1980s, the Bushmen were cleared from their lands in a wave of forced evictions. Although they were allowed to return in 2006, they were denied access to a borehole, their main source of water. Although the government allowed Gem Diamonds and Wilderness Safari access to water, the Bushmen had to resort to collecting rainwater, melons and roots for drinking water.
The Botswana Court of Appeal ruling notes the recognition of the human right to water at the UN and serves as a precedent for all countries regarding respect for the human right to water in domestic law.

What Will Power the Future of Trains – Hydrogen or Batteries?
Trains may seem outdated to some, but they're one of the most eco-friendly modes of transportation. Even diesel trains produce fewer emissions per passenger per kilometer than cars and planes. Electric trains are also gaining popularity, with both battery-powered and hydrogen options available. Given current climate concerns, the move to electric trains is inevitable. It's not a question of whether railroads will go electric, but rather how they'll do so. Both hydrogen and batteries show significant promise, but which technology will become the standard for future locomotives? The hydrogen-versus-batteries debate isn't a new one, and it likely won't go away … Continue reading

Students Uncover Best Approach to Avoid Urinal Splash-Back
A group calling themselves the wizz-kids at Brigham Young University have taken on the dirty task of studying the physics of urine splash-back caused by urinals. What do they say is the best approach to avoid splash-back?
To be as thorough and sanitary as possible during the experiment, the wizz-kids built liquid dispensing nozzles equipped with high speed cameras to capture the vital data. What did the data tell them about avoiding splash-back?
- Aim for the back of the urinal and avoid the pool around the drain
- Stand as close to the urinal as possible to prevent the flow from breaking up into drops before hitting the back of the urinal
- Try to make the angle of impact as downward as possible
I don't know about you, but being a twenty-something male I feel like I've had enough urinal time to be designated some sort of scientist in the field of liquid dynamics. Without getting into too much detail, I can endorse the above tips for avoiding splash-back and offer a few of my own.
A bit of wizzdom for my fellow man:
- Sit while peeing (not just for the ladies anymore)
- Restrict your stream's flow physically (sounds painful)
- Putting a preemptive layer of toilet paper into the bowl (when using a traditional toilet)
- Request your work, favorite bar or restaurant invest in one of these babies
Do you have any tips for the urinal-challenged men out there?

Testing of trawl-acoustic stock estimation of spawning capelin 2020 (Toktrapport nr. 2-2020) (PDF)
Tema: Lodde – Barentshavet
This report describes the second in a series of three trawl-acoustic monitoring surveys of the spawning stock of capelin during the migration to the coast. The survey is a response to a proposal from the industry to evaluate the possibility of using winter monitoring of maturing capelin as an input to the capelin assessment and advice. The timing and geographic coverage of the survey are such that they would be relevant to use for advice given that the output is reliable. Pre-defined areas off the Troms and Finnmark coast were covered using two vessels, Vendla surveying the western part and Eros the eastern part. A stratified random transect design was adopted with two complementary zig-zag grids, the first going in a west-east and the second in an east-west direction over the same strata. The ultimate biomass estimate combines the two coverages, but evaluation about the mobility of the fish can be done by comparing the coverages. The final geographical allocation of survey effort was decided based on information from the scouting vessel Hovden Viking which covered the area a week prior to the main survey. Echo sounders with frequencies from 18-200 kHz were run together with sonars, and target trawls were carried out on significant pelagic aggregations. Capelin abundance was estimated using 38 kHz data. The total biomass of maturing capelin in the coverage area was estimated at 62 298 tons, with a CV of 38%. The 5% lower and 95% upper confidence limits were 26 655 and 104 305 tons, respectively. The result is in accordance with the prediction from the autumn 2019, but the high CV and wide confidence interval show that the survey result is uncertain. The high uncertainty despite the good survey coverage is likely due to the very patchy distribution of the capelin. In addition, in the western coverage area which had most of the capelin recordings, there was a big difference in both estimate and distribution in the return east-west coverage compared to the west-east. This underlines the high mobility of the capelin when it is in this state of migration. The strong dynamic was also evident last year and makes the monitoring of the capelin spawning migration challenging. Mean length of the capelin was 16.2 cm, mean weight 22.3 g, and maturation had progressed further in the western than the eastern area which was the opposite of what was observed last year. Methodological investigations including target strength measurements and testing of the autonomous Sailbuoy were carried out successfully and are described in the report. A thorough evaluation of the survey series and its usefulness as input to the capelin advice will be done after the third survey in this series is completed.

Stock and Flow in Knowledge Management
The term knowledge management can be defined as the process in which value from their knowledge based assets are generated by the organization. Generating value from such assets involves the knowledge documentation of employees, partners and customers; and then sharing those ideas with the employees, departments and also with that of some other companies to formulate the best practice out of it. So let us have a look at stock and flow in knowledge management.
About stock and flowIn a share market, stock is a familiar term in management as it is quite often used in the same. Therefore by the term stock we can brief it by saying that it is something which is in hand and can be used to its best at the necessary point of time. Flow is a term which ensures that the available stock is transferred from a point to the other in an appropriate manner so as to create a healthy knowledge management system.When dealing with knowledge management the concepts of stock and flow are often used. The stock of knowledge represents the level of knowledge of an employee or can even be of the organization as a whole. The flow of knowledge in knowledge management indicates the amount of knowledge which is transferred between people so as to devise sound organizing activities. The concept of stock and flow helps us to give an insight on the matters of knowledge management. This is because of the fact that they are already common to us as they are used in some of the other areas, and we have also learned them at school. When you go for stock market, it is better if you go for share tips.
Role of stock and flowStock and flow play a vital role in the functional development of an organization. An organizations development depends up-on the employees and the management. The stock of knowledge is saved on human which is the source of knowledge. Through our lives, we have collected much information and built up some knowledge which is stocked in theIndian stock market. These stocks are not useful for an organization till it is implemented. The employees need to put their ideas (stock) and let it pass (flow) to that of the management, and the management then study it and will go for a sound knowledge management. There can be someone in the team who is capable of fulfilling certain job but is reluctant to do it then there is no use of this stock of knowledge. Therefore in parallel with business an organization would be able to grow and develop only then when there is an increase in the productivity. And productivity can be increased with an increase in the flow of knowledge so that the stock of knowledge remains the same and there is no hiring of extra employees or some external consultants.
To show the concept of stock and flow in knowledge management we can go through the following example: To analyze the economic system the stock and flow concept can be implemented. In economics the flow of money is the velocity of money which can also be said as the circulation process. Thus the quantity theory of money states that this velocity of money can be defined as the ratio of net national product in current prices to the money stock.The flow of current through electric circuit which is tempered by a certain resistance is all about basic electronics. For certain amplitude of current the given resistance in the network needs provisioning power i.e. the voltage. The current absorbed by the resistor need more power. Thus the flow (current) and the resistance (stock) operate in a reciprocal proportional way.
So, you have come to know about stock and flow in knowledge management.

TIMMS CITY, TX
TIMMS CITY, TEXAS. Timms City was four miles southwest of the site of present Darrouzett in northern Lipscomb County. It was begun in 1887 and was one of two towns competing with Lipscomb to become county seat. It was named for George Timms, a Kansas financier who backed the community. Soon, Timms City had a hotel, several saloons, a post office, a newspaper (the Texas Tribune), and various other businesses. However, the election of Lipscomb as the permanent county seat quickly led to the town's demise. One county businessman, H. E. Hoover, described it as "one year growing and four years dying." By the time the Panhandle and Santa Fe Railway pushed through this portion of the county in 1919, Timms City had disappeared.

How it is preserved
ASI started using fuller's earth with a mixture of aluminium silicate and magnesium trisilicate to remove tarry/greasy particulate matter in 1984. Today, ASI claims it has stopped using harmful chemicals and only adds glycerol, cellosolve and sodium bicarbonate to the mud pack in summers to ensure that it does not dry out fast.
An alkaline solution of ammonia is used to clean the red sandstone. ASI uses a special biocidal treatment for the sandstone portions that are hidden from sun and gather moss and algae because of humidity. Preservatives are also used to increase the longevity of the stone.
Stones of the inlay work are replaced if they get damaged or broken. Earlier, artisans were chosen through a tender system. The process was discontinued after it drew criticism because the lowest cost did not assure quality work. ASI now hires artisans based on their craftsmanship, but still has no guidelines for hiring them.
Sandstone floors are in a more precarious condition than the marble floors because of their high porosity that locks moisture inside. As a result, the red sandstone floors are chipping at many places. ASI has put barricades near the Mehman Khana to stop visitors from stepping on them.
Wooden stairs have been added to decrease the pressure on marble floors and staircases and avoid wear and tear. The monument was constructed to take the weight of 30-40 people at a time. Today, over 10 million tourists visit it annually and the footfall is wearing out the walkways of its garden and the floors of its terraces.

Septennial Act, 1716. This Act prolonged the life of Parliament from a maximum of three years (as the 1694 Triennial Act required) to seven years. Its pretext was the Jacobite uprising in 1715. But by delaying the next election until 1722 the new Whig ministers succeeded in evading electoral judgement until they had consolidated themselves in power and weakened their Tory opponents. Following the 'rage of party' of Queen Anne's day, the longer periods between elections did much to quieten political life and entrench the Whigs in government for the next three decades. The Parliament Act of 1911 shortened the duration of parliaments to five years.

How do __hash__ and __eq__ use in identification in sets? For example some code that should help to solve some domino puzzle:
class foo(object):
 def __init__(self, one, two):
 self.one = one
 self.two = two
 def __eq__(self,other):
 if (self.one == other.one) and (self.two == other.two): return True
 if (self.two == other.one) and (self.one == other.two): return True
 return False
 def __hash__(self):
 return hash(self.one + self.two)
s = set()
for i in range(7):
 for j in range(7):
len(s) // returns 28 Why?
If i use only __eq__() len(s) equals 49. Its ok because as i understand objects (1-2 and 2-1 for example) not same, but represent same domino. So I have added hash function.
Now it works the way i want, but i did not understand one thing: hash of 1-3 and 2-2 should be same so they should counted like same object and shouldn't added to set. But they do! Im stuck.

Equality for dict/set purposes depends on equality as defined by __eq__. However, it is required that objects that compare equal have the same hash value, and that is why you need __hash__. See this question for some similar discussion.
The hash itself does not determine whether two objects count as the same in dictionaries. The hash is like a "shortcut" that only works one way: if two objects have different hashes, they are definitely not equal; but if they have the same hash, they still might not be equal.
In your example, you defined __hash__ and __eq__ to do different things. The hash depends only on the sum of the numbers on the domino, but the equality depends on both individual numbers (in order). This is legal, since it is still the case that equal dominoes have equal hashes. However, like I said above, it doesn't mean that equal-sum dominoes will be considered equal. Some unequal dominoes will still have equal hashes. But equality is still determined by __eq__, and __eq__ still looks at both numbers, in order, so that's what determines whether they are equal.
It seems to me that the appropriate thing to do in your case is to define both __hash__ and __eq__ to depend on the ordered pair --- that is, first compare the greater of the two numbers, then compare the lesser. This will mean that 2-1 and 1-2 will be considered the same.

Still not all clear. It stop work if i comment __hash__ or __eq__. And I still dont know why it works now. Is it uses both __eq__ and __hash__ to determin in?

The hash is only a hint to help Python arrange the objects. When looking for some object foo in a set, it still has to check each object in the set with the same hash as foo.
It's like having a bookshelf for every letter of the alphabet. Say you want to add a new book to your collection, only if you don't have a copy of it already; you'd first go to the shelf for the appropriate letter. But then you have to look at each book on the shelf and compare it to the one in your hand, to see if it's the same. You wouldn't discard the new book just because there's something already on the shelf.
If you want to use some other value to filter out "duplicates", then use a dict that maps the domino's total value to the first domino you saw. Don't subvert builtin Python behavior to mean something entirely different. (As you've discovered, it doesn't work in this case, anyway.)

You can read about this in the Python data model documentation, but the short answer is that you can rewrite your hash function as:
def __hash__(self):
 return hash(tuple(sorted((self.one, self.two))))

this would get him further from what he wants; 1 2 and 2 1 would once again count as the same domino. but he should be doing this anyway, yes. :) – Eevee Jan 16 '13 at 6:35

The requirement for hash functions is that if x == y for two values, then hash(x) == hash(y). The reverse need not be true.
You can easily see why this is the case by considering hashing of strings. Lets say that hash(str) returns a 32-bit number, and we are hashing strings longer than 4 characters long (i.e. contain more than 32 bits). There are more possible strings than there are possible hash values, so some non-equal strings must share the same hash (this is an application of the pigeonhole principle).
Python sets are implemented as hash tables. When checking whether an object is a member of the set, it will call its hash function and use the result to pick a bucket, and then use the equality operator to see if it matches any of the items in the bucket.
With your implementation, the 2-2 and 1-3 dominoes will end up in the hash bucket, but they don't compare equal. Therefore, the both can be added to the set.

The SWING Project (Smart WIng for New Generation UAV for Civilian Use) aims to study composite materials, composite material processes, composite structure design methods, Actuation Systems and Health Monitoring Methodologies to be applied for an civil UAV aircraft.
Italsystem in involved in this project (founded by MISE) with other major national companies, in order to improve the pre-competitive advantage of the Italian aerospace industry in the growing market of remote-controlled aircraft (UAV).
The objectives of this project are:
1. Make demonstrator of a UAV swing in composite material and test it statically. The target is to reduce the weight at least of 10% respect the usage of classic material and to reduce the cost at least of 5%.
The main challenge is the availability of a composite materials database to use in design: the qualification process of the material is a technological barrier if you want to certify an aeronautical product. The very high certification cost is a limit and usually only the major aerospace OEMs can face it. One goal of the project is to qualify at least two materials.
2. Develop an Electro-Mechanical Actuator (EMA) and related control unit (ECU) to integrate in the wing. The target is to implement a highly critical actuation system (DAL A, a failure on 10-9 FH).
ItalSystem was selected for the design and development of the ECU, due to its twenty-year experience in the design and certification of avionic and embedded systems.

Presidential Campaign
During the 2016 Presidential Campaign, American Christian Leaders for Israel (ACLI) submitted a letter to each of the presidential candidates highlighting the chief principles deemed necessary to maintain the valuable friendship between Israel and the USA. Some 650 Christian leaders signed this letter demonstrating to the candidates that together we represent many millions of Christians in the United States who recognize the mutual benefit to both nations of a close strategic partnership with Israel.
The vast majority of the American people support Israel, and we felt it was our responsibility to make sure that the next President of the United States reflects the will of people and stands in friendship with the nation and people of Israel.
 1. Implement the Jerusalem Embassy Act of 1995 and relocate the US Embassy in Israel to its capital city of Jerusalem.
 2. Renew and strengthen the US's Memorandum of Understanding to fund Israel's growing security needs.
 3. Combat any efforts at the local, state, or federal level to boycott, divest from, or sanction Israel.
 4. Monitor Iran's ongoing violations of sanctions and to toughen current sanctions as well as impose new ones as necessary.
 5. Oppose any imposed solutions to the Palestinian conflict on Israel by outside parties, including the United Nations Security Council.
Israel, an island of hope and freedom, lives in an increasingly stormy sea of despair and terror. Now more than ever, we must speak in a unified voice to our future leaders to ensure a strong stance with our Israeli friends.

Problem Details
The idea of the problem is to find out how long it would take to flush the Great Lakes of pollution. They're set up as a series of five tanks and you are given inflow rates of clean water, inflow rates from the other tanks, and outflow rates.
For our model, we make the following assumptions:
 1. The volume of each lake remains constant.
 2. The flow rates are constant throughout the year.
 3. When a liquid enters the lake, perfect mixing occurs and the pollutants are uniformly distributed.
 4. Pollutants are dissolved in the water and enter or leave by inflow or outflow of solution.
Before using this model to obtain estimates on the cleanup times for the lakes, we consider some simpler models:
 - (a) Use the outflow rates given in the figure to determine the time it would take to "drain" each lake. This gives a lower bound on how long it would take to remove all the pollutants.
 - (b) A better estimate is obtained by assuming that each lake is a separate tank with only clean water flowing in. Use this approach to determine how long it would take the pollution level in each lake to be reduced to 50% of its original level. How long would it take to reduce the pollution to 5% of its original level?
 - (c) Finally, to take into account the fact that pollution from one lake flows into the next lake in the chain, use the entire multiple compartment model given in the figure to determine when the pollution level in each lake has been reduced to 50% of its original level, assuming pollution has ceased (that is, inflows not from a lake are clean water). Assume that all the lakes initially have the same pollution concentration $p$. How long would it take for the pollution to be reduced to 5% of its original level?
Great Lakeshttp://img856.imageshack.us/img856/8329/6p2z.png
Solution so far:
$\frac{dA}{dt}$ = rate in-rate out where $A$ is the amount of pollution at time $t$.
First I wrote equations for each lake. Rather than using $A$ as my variable, I used the first letter of each lake (with $n$ for Ontario) to stand for the amount of pollution in the given lake at time $t$. This gives...
$\frac{ds}{dt} = \frac{-15s}{2900} $
$\frac{dm}{dt} = \frac{-38m}{1180} $
$\frac{dh}{dt} = \frac{15s}{2900} + \frac{38m}{1180} - \frac{68h}{850} $
$\frac{de}{dt} = \frac{68h}{850} - \frac{85e}{116} $
$\frac{dn}{dt} = \frac{85e}{116} - \frac{99n}{393} $
Rearranging and pulling out the differential operator leads to the following system:
$(D + \frac{38}{1180})[m] = 0 $
$(D - \frac{68}{850})[h] + \frac{38m}{1180} - \frac{15s}{2900}=0 $
$(D + \frac{15}{2900})[s] = 0 $
$(D + \frac{85}{116})[e] - \frac{68h}{850} = 0 $
$(D + \frac{99}{393})[n] - \frac{85e}{116} = 0 $
This is where I'm stuck. I have this system of five equations with five variables. It seems like it should be fairly straightforward to solve from here, but I can't figure out what to do next.

Just for the sake of brevity, I have converted all the fractions into decimal form ie
$\frac{38}{1180} = 0.0322$
$\frac{68}{850} = 0.0800 $
$\frac{15}{2900} = 0.0051$
$\frac{85}{116} = 0.7327$
$\frac{99}{393} = 0.2519$
I am going to use the Laplace method for converting these differential equations into algebraic equations, thereby we will solve the equations and get the Laplace transforms of $S,H,M,E$ and $N$ and then take the inverse Laplace transforms of these to get the final equations of pollution for these lakes. Now $s(0) = h(0) = m(0) = e(0) = n(0) = p$, since the initial conditions are same for all the lakes.
Therfore using Laplace notation we have,
$sS - s(0) + 0.0051S = 0 $
Therfore $S = \frac{p}{s+.0051}$
Similarly we have $ M = \frac{p}{s+0.0322}$
Now for (2) differential equation we have
Applying Laplace we will have
$ H = \frac{-.0322p}{(s+.0322)(s+.08)}\frac{.0051p}{(s+.0051)(s+.08)}+\frac{p}{(s+.08)}$
Similarly, you can plug in this value of $H$ in the remaining differential equations ( along with the value of $M$ and $S$ found previously to find the Laplace expressions for $E$ and $N$, and then take the Laplace inverse of all and you will get the equations for all lakes.
Now for getting $5\%$ time, just put $0.05p$ and equate it to get $t$ for each case.

So to get the 5% time I do 0.05p and for 50% it's 0.5p? – Contourette. Dec 9 '13 at 10:03
Yes you have to put $0.05p$ for 5% and $0.5p$ for 50%. – AbKDs Dec 10 '13 at 0:44
I haven't studied Laplace yet so could you give me an idea of Paul Safier's answer? I've commented to his solution. – Contourette. Dec 10 '13 at 9:49
I will definitely give a try :)! – AbKDs Dec 10 '13 at 10:52
_USER_, I realised the equations that you have written and we have subsequently solved are for part (c). Actually in part (b) says to just assume separate tanks, ie no pollution comes in only it goes out. Say for Ontario the equations will be $\frac{dn}{dt} = \frac{-99}{393}n$ ie no incoming flow of pollution (only outgoing pollution). So (b) part is very straightforward. The solutions me and Paul Safier have written are for part (c). – AbKDs Dec 10 '13 at 14:50
Now that you have your system of differential equations defined, you can start solving them. The equations for $s(t)$ and $m(t)$ are not coupled so you can solve those first. All equations have the initial condition of $p$ amount of polutant. After you solve for $s(t)$ and $m(t)$ (and let me know if this is a problem) you can plug in those to the equations for $h(t)$. After you have $h(t)$ you can get $e(t)$ and finally $n(t)$. Then for each equation plug in $0.05 p$ for the concentration and solve for $t$ to determine the time it takes for the concentration in each lake to drop to 5% of the original concentration.
For example, the solution of $s(t)$ is: $$ s(t)=p e^{-\frac{15}{2900}t}. $$ Setting $s=0.05p$ and solving for time gives $t=579$. Do the same for the others.
Does this help any?

Okay so I have some uncertainties while solving. As you said I computed the $s(t)$ and $m(t)$ and replaced in $h(t)$. Though when computing $h(t)$ I got really large numbers and I'm not sure if it's correct. Then another question I have is about b). So to compute the time to reduce to 5% you said it's $0.05p$ so that means for 50% is $0.5p$? And for the question at c), I don't really understand what it asks. I mean, the input of a lake is equal to the output ( taking into consideration the clean water) so I have no idea what it asks.I edited the requirements adding last 2 lines to c. Thanks – Contourette. Dec 7 '13 at 12:58

UPDATE: The Canadian International Trade Tribunal Ruled That Centrifugal Opening Knives are Prohibited Weapons
The Canadian International Trade Tribunal (CITT) ruled that knives in which the blade is released via centrifugal force are classified as prohibited weapons. The CITT is an independent quasi-judicial body that administers Canada and international rules that govern trade. CITT reports to the Minister of Finance and Parliament. CITT reviews five key areas:
â€¢ Anti-Dumping Inquiries (dumping refers to the practice of another country selling goods at below competitive prices which injures domestic companies);
â€¢ Procurement Inquiries (the federal government is bound by certain procurement rules)
â€¢ Economic and Tariff Inquiries (provide advice to the government on trade matters);
â€¢ Customs and Excise Appeals
â€¢ Safeguard Inquiries (complaints by domestic companies that increased imports are injuring domestic industry and recommendations on how to address those issues).
How does CITT work?
CITT operates similarly to a lower court. The parties are given notice of hearings; each side may present evidence and give testimony. The tribunal can also request information. All hearings are open to the public and are held in the CITTâ€™s offices in Ottawa, Ontario. Moreover, if parties or witnesses or uncooperative, CITT may issue subpoenas for witnesses, documents, and records.
What knives are affected?
The decision was Appeal No. AP-2017-012, T. LaPlante v. President of the Canada Border Services Agency. The dispute centered on subsection 84(1) of the Criminal Code. All knives that meet the following qualifications are classified as prohibited:
1. If the knife requires simultaneous or preliminary minimal manipulation of a non-edged or â€œflapperâ€ part of the blade; and
2. The blade opens via centrifugal force. For example, if the blade is released from the handle and into a locked position with a simple and quick outward flick of the wrist.
These knives are like switch-blades except they rely on centrifugal force, rather than mechanical, to eject the blade.
Effect of the ruling
As of the date of the ruling, the CBSA is required to prohibit the import of all knives that meet the above-stated qualifications. You can import the blade if you are (1) business and (2) possess a valid Firearms Business License that (3) is presented with the prohibited weapon(s) and (4) it is for business activity.
If you are concerned about the effect of this ruling and other by CITT, consider speaking with an Argo Customs broker for assistance. Argo Customs brokers are constantly updating their clients on the importation of prohibited weapons into Canada and other rules that may affect your business.

Seattle, Washington: Frank B. Cooper
Elementary School is historically associated with Mrs. Thelma Fisher Dewitty, who holds the distinction of being the first African American to teach within the Seattle Public School District. Mrs. Dewitty began her long distinguished career at the school amidst public pressure and racial tension. Born in Beaumont, Texas in 1912, she received a bachelor's degree at Wiley College in Marshall, Texas, in 1941. Prior to her arrival in Seattle, Dewitty had been a teacher for 14 years--nine years in Corpus Christi, Texas, and five years in Beamont, Texas. She came to Seattle with her husband and attended graduate school at the University of Washington. After Advocacy on her behalf from the Seattle Urban League, the NAACP, the Civic Unity Committee, and the Christian Friends for Racial Equality, Mrs. Dewitty became the first African American teacher in the Seattle School District. Her teaching career in Seattle began at Cooper School in September 1947.
Although Seattle was known for racial tolerance, Dewitty's appointment was a groundbreaking accomplishment. Her hiring generated some conflict, and when she was hired at Cooper School, Principal Lester Roblee informed the other teachers that a black teacher would be joining the staff. He gave them the option to transfer. During the first year one parent asked that her child be removed from Dewitty's class--a request rejected by the principal. Dewitty left Cooper Elementary School in 1953 and taught at numerous other schools within the Seattle School District including John Hay (1953-55), Laurelhurst (1955-56), and Sandpoint (1956-58) Elementary Schools. She officially retired from the Seattle Public School District in 1973. In the civic arena, Dewitty was active in the Seattle Branch of the NAACP, serving as its president in the late 1950s. She also served on the State Board Against Discrimination and on the Board of Theater Supervisors for Seattle and King County.
Thelma Dewitty's presence at Cooper School symbolized two major changes in the Seattle area after World War II. Suffering greatly from a shortage of male teachers during World War II, the School Board had to relax its rules regarding the ineligibility of married women teachers, and eventually eliminated the rule altogether in 1947. Meanwhile, the enormous wave of African American migration to the Seattle area included many black professionals seeking employment. As the first African American to teach in Seattle's school district, Dewitty's appointment in September of 1947 began to break down the deep racial barriers that existed there. Her hiring came 50 years before John Stanford became Seattle's first black school superintendent. Shortly after her appointment, a second African American woman, Marita Johnson, was hired to teach Household Service, one of the newer "school to work" courses at Broadway-Edison Technical School.
In 1917 the noted Seattle architect Edgar Blair designed the Frank B. Cooper Elementary School
in the American Renaissance style, with rectangular massing, hipped roof, and a minimum of architectural detailing. In 1929 additions were added to the east and south by another noted Seattle architect, Floyd Naramore. The main building is a three-story rectangular block with a gable-on-hip roof. Located on both the west and east elevations of the roof are three ventilation towers with louvered openings. The roof is covered with asphalt shingles and the exterior of the building is clad in red brick.

The PNE forces were supposed to enter the Congo System, overwhelm the Royal Torch Navy, and wipe out all life on the surface of the planet Torch with a kinetic bombardment. However, the Maya Sector Detachment learned of a planned operations by units of Havenite exiles and deduced the likely location of the operation. It sent its brand new Light Cruiser Squadron 7036 to Torch and intercepted the attack.
In the end, the PNE force was destroyed in the Second Battle of Congo (October 1921 PD), and its remnants didn't attempt the planned kinetic bombardment. The Kingdom of Torch survived without damage. (CS2)

Brothers is a single-player cooperative game where the player controls two brothers independently and simultaneously. The game starts in a village where the two young brothers live. Their mother drowned in the sea and their father is ailing. The two set out to find the Water of Life, which is said to hold the power to cure their father. Both brothers are controlled separately for movement and actions. The game strings together various scenes where the brothers must solve puzzles by helping each other, for instance by pulling levers, dragging items, distracting dangerous characters or operating a catapult. Not by controlling them separately, but often both at the same time. Next to movement they can also climb, hang from ledges and slide down. There are a few enemies along the way, but these cannot be fought directly. Instead, a more inventive approach needs to be found.
The game focuses on exploration and especially environment-based puzzle-solving to progress. The game is shown with a third-person view, often shown from a distance or above, and with a fixed camera. The level design is linear with a single path to progress. It also contains various sequences not related to the main quest where the brothers have fun together, to establish the atmosphere. The environment has a fantasy-like atmosphere with different locales such as villages, mountains, a sequence where they travel by boat over a river, a frozen landscape etc.

Spectrum Synthesis Modeling of the X-Ray Spectrum of GRO J1655-40 Taken During the 2005 Outburst
Kallman, T. R.
Bautista, M. A.
Miller, J. M.
MetadataShow full item record
The spectrum from the black hole X-ray transient GRO J1655-40 obtained using the Chandra High Energy Transmission Grating in 2005 is notable as a laboratory for the study of warm absorbers, and for the presence of many lines from odd-Z elements between Na and Co ( and Ti and Cr) not previously observed in X-rays. We present synthetic spectral models which can be used to constrain these element abundances and other parameters describing the outflow from the warm absorber in this object. We present results of fitting to the spectrum using various tools and techniques, including automated line fitting, phenomenological models, and photoionization modeling. We show that the behavior of the curves of growth of lines from H-like and Li-like ions indicate that the lines are either saturated or affected by filling-in from scattered or a partially covered continuum source. We confirm the conclusion of previous work by Miller et al., which shows that the ionization conditions are not consistent with wind driving due to thermal expansion. The spectrum provides the opportunity to measure abundances for several elements not typically observable in the X-ray band. These show a pattern of enhancement for iron peak elements, and solar or subsolar values for elements lighter than calcium. Models show that this is consistent with enrichment by a core-collapse supernova. We discuss the implications of these values for the evolutionary history of this system.

ISBN13: 978-_PHONE_
ISBN10: _PHONE_
Summary: Now in its second edition, Drugs and Human Lactation is a comprehensive guide to the content and consequences of xenobiotics and micronutrients in human milk, and remains by far the most thorough and extensive work available on this subject. The excellent methodology used for the compilation of the 1st edition has been retained.
It begins with an outline of the processes by which substances enter milk during its formation, the effects of drugs on the milk product moreion process, the main determinants of drug excretion into milk and their disposition in the child. There follows an analysis of current data on 234 individual drugs, describing the extent of their passage into human milk, and assessing the risk to the suckling infant. Vitamins and essential trace elements, and radiopharmaceuticals are similarly reviewed. Also included is an account of the factors that influence the passage of environmental and occupational chemicals into milk. The result is a complete overview of what is known and proven, with clear pointers to matters which require further study, and brings the various subject areas up to date. Risks, uncertainties and false alarms which exist have been defined in such a way that they can be avoided.
Once again, Drugs and Human Lactation provides a comprehensive guide to the content and consequences of substances in milk. The volume will provide a rational basis for making therapeutic decisions in women who seek to breast-feed. less

Schottky Effect
Points to understand which are related to Schottky effect are the following:In a solid material, there will be two or less than two electrons for each atom which are free to move from one atom to another based on band theory. Work Function: The bare minimum quantity of energy (produced due to thermal energy) essential for an electron to escape (leave) from the surface of a material is called work function. Thermionic Emission: It is the emission (release) of charge carriers (ions or electrons) from the surface of a material due to the thermal energy given to it. Thermionic Emission Current: As a result of thermionic emission (electron ejection due to thermal energy), an electric current will be produced across the electrodes which is termed as thermionic emission current. Work function is inversely proportional to thermionic emission current. Richardson's Law: It is mathematically analogous to Arrhenius equation. It gives the relationship between the current and the temperature of a heated wire. That is, the current will depend on the temperature of the wire exponentially as shown below. J → Emission Current density W → Work function of the metal T → Temperature of the metal K → Boltzmann constant = AG = λR A0 λR → Material specific correction factor (typically of order 0.5) A0 → Universal constant =
Now, we can come to the topic – Schottky Effect (Field enhanced thermionic emission). Here; when we apply an electric field to a heated material, the emission of electrons from the surface increases. It results in decreasing the smallest energy required for the release of electrons from the surface of the material (work function) and thereby increasing thermionic current. If a very small electric field is applied, then it only sweeps the previously released electrons from the surface of the material. While increasing the field (moderate field), a particular point is reached at which the work function value gets decreased. If the field is further increased, it results in decreasing in work function and thereby increasing the thermionic emission current. This is Schottky effect. In the absence of electric field, the surface barrier which is seen by the emitting Fermi-level electron will be W height. This height is equal to the work function. But the electric field will decrease the barrier height by an amount equal to ΔW (see figure 2) and thus increasing the thermionic current. This can be modelled by an easy alteration in Richardson equation which is explained before. In that equation, we can substitute W by W + ΔW as shown below. The above equation satisfies only for electric field strength less than 108 V/m. But for very high increase in electric field; it results in tunnelling of electrons (excessive electron emission) through the potential barrier. This type of emission or tunnelling is called as high-field emission or simply we can say field emission.
When we plot a graph of logarithm of thermionic emission current and will give a straight line (shown below). At low anode voltage, the deviation is due to space charge effects. schottky effect The electric lines of force are at 90o to the surface of a metal due to high conductivity (see figure below). The inter-atomic distance is assumed to be 'a'. Thus, an electron which is located at a distance x>a from the surface having charge – e interacts with surface. It induces an electrical image (+e) in the metal which will be at a distance of x. There will be an attractive force between – e and + e given by schottky effect

The curly hair tarantula is a common name most often attributed to Tliltocatl albopilosus (formerly known as Brachypelma albopilosum), a dark-colored tarantula with thick, bristly hair covering its legs and the majority of its body. Although all species of tarantulas do have hair, the contrast of the lighter colored hairs and the distinct curl gives the curly hair tarantula a rather unique appearance. They are a calm, ground-dwelling, beautiful spider, and like many other tarantulas in the genus Brachypelma, curly hair tarantula care is relatively simple — perfect for those newly interested in joining the hobby of tarantula keeping.
Get to Know the Curly Hair Tarantula
The curly hair tarantula is native to both Nicaragua and Costa Rica. It is a terrestrial species often found at the bases of tree trunks, near rivers and inside the holes and dens left behind by rodents or other small animals. In the wild, they are listed as "near-threatened," with the greatest threat being habitat loss, as they are very rarely imported in this current day. Almost all of the curly hair tarantulas available in the pet trade come from captive breeding efforts, both from private and well-known keepers across the world.
The curly hair tarantula is considered average size among tarantulas, with a leg span of about 5½ inches. The females tend to live between 8 to 10 years in captivity, while males only live to be around 4 years-old or so.
Behavior & Temperament
The curly hair tarantula is docile species, which makes it a personal favorite among those who enjoy handling their spiders. As a New World tarantula, the curly hair is more likely to kick off some of the thick urticating (stinging) hairs from its abdomen as opposed to delivering a bite. Despite the term, these are not actually "hairs." It is a misnomer; only mammals possess true hairs. They are actually fine, bony extensions from the spider's exoskeleton that possess a mild toxin that can cause irritation if exposed to the skin. Because this is one of the animal's primary defense mechanisms, they can sometimes develop a bald spot on their abdominal area due to repeated kicking. However, the "hairs" will be replenished after the next molt.
The curly hair tarantula possesses venom and the capacity to bite if it feels threatened, as do all tarantulas. The pain has been described as similar to that of a bee sting, but if you are known to be severely allergic to bees, you should be extremely cautious when handling your tarantula.
For an adult curly hair tarantula, a secure enclosure with the floor space roughly the size of a 10-gallon aquarium is more than adequate. Since tarantulas are a terrestrial species, horizontal space is always more important than height, as too high of an enclosure can result in falls and unnecessary harm to your animal. Unlike many other species, the curly hair tarantula can often be seen out and about inside its enclosure.
It is still absolutely vital to provide your tarantula with areas to hide, such as bark, wood pieces or even small pots. If given enough substrate, the curly hair tarantula will burrow, lining the outer area and the inner walls with its silk to create a home for itself. The suggested depth of bedding for the curly hair tarantula is about 3 to 4 inches. They are known to "redecorate" their enclosure, and can be spotted many times moving clumps of dirt and décor to their liking. Plastic or acrylic enclosures are better at keeping both consistent humidity and temperature levels, however some minor modifications can be made to a glass enclosure to reach these requirements as well.
For proper curly hair tarantula care, the humidity should be somewhere between 60 and 70 percent, which can easily be achieved by keeping a proper mix of substrate and a small water dish. A good mix of pesticide-free potting soil, vermiculite and sphagnum moss can help keep your humidity inside the enclosure at proper levels. When watering your curly hair, a little bit of spillover to allow just enough moisture to soak into the substrate is ideal, but the idea is to not moisten the area so much that the substrate is constantly wet. Too much humidity will stress your tarantula. Additionally, if you are unsure about the humidity levels, purchase a hygrometer as well as a temperature gauge to monitor both your temperatures and humidity levels.
Ideally, this species needs a temperature range between 75 and 80 degrees Fahrenheit. This can be achieved either by keeping the room where your curly hair tarantula lives warm, or by adding a heat mat to the side or bottom of the enclosure. Be careful to monitor the heat so it doesn't get too hot for your tarantula, and always offer a cool side of the enclosure in the event that it gets too warm for your pet.
Spot cleaning is about all the cleaning necessary for most tarantulas, with the occasional deep cleaning every six months or so if deemed necessary by the keeper. Remove discarded or uneaten food immediately to prevent mold as well as unwanted pests such as gnats.
Curly Hair Tarantula Diet
Curly hair tarantulas aren't known to be picky eaters, as they are opportunistic feeders in the wild. In their native range, anything small enough to be overpowered by the tarantula is fair game. However, in captivity, it is important to take certain precautions when preparing the curly hair tarantula diet. Offering appropriate-sized feeders is important to reduce the risk of injuries that could be sustained during the feeding process.
Dubia roaches, mealworms, live crickets and other insects are almost all easily obtainable curly hair tarantula food that can be found at many pet stores. Offering a variety of feeder insects for curly hair tarantulas ensures that they get the proper nutrients, as does making sure that your feeders are "gut-loaded" — if they are fed well, your pet is fed well, too. A small pinky mouse can be offered as a treat, but many keepers advise against feeding your tarantulas things that are very high in calcium. Never offer your curly hair tarantula insects or any sort of small feeder from outside. This poses a danger to your pet, as the outside insects could be loaded with internal parasites as well as potentially deadly pesticides.
Most hydration is obtained through the feeding process, however, offering a small, shallow water dish, even something as small as a bottle cap, provides your pet with the option to drink if necessary. Be sure to keep the water dish clean, as it's not uncommon for a curly hair tarantula to move its water dish (if small enough) or fill it up with debris during another redecorating session.
If you notice that your tarantula is slowing down, refusing to eat or hiding more than usual, do not be alarmed right away! It could very well be entering the somewhat lengthy process of a molt, where it will grow and shed its entire exoskeleton. You may come home and think you see two tarantulas in the enclosure, but the second one will be the molt, which will need to be removed. A knowledgeable keeper can even determine the sex of a tarantula through its molt, and some simply like to keep the molted skin as a keepsake. Regardless of what you choose to do, if you notice that your curly hair tarantula appears to be molting, remove any live feeders and keep your tarantula's water dish filled. The humidity helps with this process, as too dry of an environment could be this species' demise.
Molting slows down exponentially as the spider matures, sometimes as infrequently as once a year for mature females, or even not at all for mature males. If you notice your curly hair tarantula on its back with its legs up, this is the beginning of the molting process. However, if you see that your tarantula is sitting with its legs tucked under itself, lethargic, or if it has a shrunken and poor looking abdomen, you should seek the help of an exotics veterinarian or experienced keeper to properly diagnose your tarantula's condition.

2. Dot diag. of ethyne.
Conc. Sulphuric acid has a very strong affinity for water, which is the reason behind its dehydrating property. It reacts with wood (which is a type of cellulose) to dehydrate it (remove the molecules of water from the wood), leaving behind a layer of carbon, which causes the black stain on the wooden shelves on which it is kept.

A trailing drawdown is a drawdown that is pegged to your positive account performance. That means that if you increase your profit by $1.00, then your trailing drawdown will also rise by $1.00. All rules, including trailing, use closed and open equity intraday.
For example, in a $25,000.00 account your starting trailing drawdown is $23,500.00.
On your first trade as you make $100.00 in profit bringing your account balance to $25,100.00. This correspondingly raises your trailing drawdown to $23,600.00.
This continues until your trailing drawdown reaches the starting balance of your account, or in this case $25,000.00, at which point the drawdown will no longer trail above $25,000.00.
You can check your current maximum drawdown in R | Trader Pro's Trader Dashboard by looking at the Auto Liquidate Threshold Value column. It'll tell you exactly what balance your account is liquidated at.

AI can detect human emotions with wireless signals
Image credit: Dreamstime
An AI has been developed that can reportedly use wireless signals to reveal peoples' inner emotions.
According to researchers from Queen Mary University of London, the use of radio waves to measure heartrate and breathing signals can be used to predict how someone is feeling even in the absence of any other visual cues, such as facial expressions.
Participants were initially asked to watch a video selected by researchers for its ability to evoke one of four basic emotion types: anger, sadness, joy and pleasure.
Whilst the individual was watching the video, the researchers sent radio signals like those transmitted by wireless systems, such as radar or Wi-Fi, towards the individual and measured the signals that bounced back off them. By analysing changes to these signals caused by slight body movements, the researchers were able to reveal 'hidden' information about an individual's heart and breathing rates.
Previous research has used similar non-invasive or wireless methods of emotion detection. However, in these studies data analysis has depended on the use of classical machine learning approaches, whereby an algorithm is used to identify and classify emotional states within the data.
For this study, the scientists employed deep learning techniques, where an artificial neural network learns its own features from time-dependent raw data, and showed that this approach could detect emotions more accurately than traditional machine learning methods.
Achintha Avin Ihalage, a PhD student at Queen Mary, said: "Deep learning allows us to assess data in a similar way to how a human brain would work, looking at different layers of information and making connections between them.
"Most of the published literature that uses machine learning measures emotions in a subject-dependent way, recording a signal from a specific individual and using this to predict their emotion at a later stage.
"With deep learning, we've shown we can accurately measure emotions in a subject-independent way, where we can look at a whole collection of signals from different individuals and learn from this data and use it to predict the emotion of people outside of our training database."
Methods to detect human emotions are often used by researchers involved in psychological or neuroscientific studies, but these approaches could also have wider implications for the management of health and wellbeing.
Ahsan Noor Khan, a PhD student at Queen Mary and first author of the study, said: "Being able to detect emotions using wireless systems is a topic of increasing interest for researchers as it offers an alternative to bulky sensors and could be directly applicable in future 'smart' home and building environments.
"In this study, we've built on existing work using radio waves to detect emotions and show that the use of deep learning techniques can improve the accuracy of our results.
"We're now looking to investigate how we could use low-cost existing systems, such as Wi-Fi routers, to detect emotions of a large number of people gathered, for instance in an office or work environment."

The northeastern Iroquois weave many types of basketry including masks. Some masks are twined from corn husks but the majority use a braid foundation coiled and stitched together. The masks made of corn husks, also called bushy-heads or husk faces, are sometimes associated with the Husk Face Society. These masks usually embody, or are inhabited by spirits associated with the corn harvest or with growing grains.
The masks are often woven by women, but are worn only by men during curing ceremonies. During ceremonies or dances, tobacco bags are often sacrificed or tobacco is burned for the husk faces. Corn husk masks frequently appear in conjunction with the wooden False Face masks. Husk face dancers do not carry a rattle or staff like the False Faces, but they do dance with a mush stirring paddle or digging stick, with which they can beat out a rhythm. Corn husk mask dancers can deliver messages about the harvest, or prepare the people for the 'grandfathers' the False Faces.
Different sized corn husk masks are made for different reasons. The full sized masks are worn by dancers during rites of the Midwinter Ceremony in January, and also for the Green Corn Ceremonies in the spring. The full sized masks can be made to represent male or female spirits, the female often having corn husk and tobacco bags or 'medicine drops' hanging from the nose, cheeks or lips. Some masks have braided noses, while others use a stuffed nose. Some masks have puffed cheeks or protruding and drooping features, denoting great age. Slightly smaller, medium sized masks are used for calling spirits and asking them for favors.
Miniature corn husk masks are used to pacify spirits tormenting a person's dreams or visions. Dreams of this sort are generally associated with the Mask Image Spirits. The person who has the dream of the spirit borrows or makes a small corn husk mask in the form of the spirit and gives it a feast including sacrifices of tobacco. After the festivities this mask is put away and kept to deter any further imposition by the spirit.
Miniature masks are also used in the formal Dream Guessing Rite. This rite occurs during the Midwinter Ceremonies and is performed by the chief and his company for a person tormented by recurring dreams of evil or trouble. The content of the dream would have to be 'guessed' with the afflicted answering only yes or no to questions about the dream. The person who guesses the dream correctly then makes a small mask and gives it, along with wishes of good fortune, to the dreamer. As the mask is the 'medicine' it is kept at home to prevent recurrence of the dreams.
Unfortunately today, Cornhusk masks are often provided less religious veneration than their wooden relatives the False Faces, yet they are both still used in sacred curing rites and in the Husk Face Society dances. Presently some corn husk masks are made without ritual blessing for museums and tourists, but all these masks deserve respect as a religious object in their cultural context.

The Psychology of Place Attachment: Why We Are Connected to Locations
Edited by Lina Maragha
"Home is where the heart is" a phrase repeated by many, is a quote that I find myself wondering about. As I sit at my desk and look at my computer which houses the entirety of university for me this year, I find my thoughts wondering off about somewhere else I would rather be. Not just anywhere, a place that I love, where the people are kind, my experiences have been memorable and my visits frequent. Place attachment is the connection one has to their favourite destination, home or location. It can be made meaningful through independent or group experiences. The psychological process of place attachment is driven by three factors, affect, cognition, and behaviour.
The Affect
We as people can bond with our locations. There is an emotional connection that may occur between person and place when it satisfies a "human need". These places bring feelings of "well-being" and "pride". It works the other way as well, in places you might have had a traumatic experience in, it is likely you will be averse to it. For example, a childhood home may be of significance but it does not always have to be associated with positive feelings.
Similar to the way music and songs bring back memories so can our location. Place attachment in response to cognition is the personal connection and meaning you can have with a given destination. These may be cottages, cities or other areas that you have frequented which is common in people and this can show "one's self-concept".
Behaviour refers to interpersonal attachment and the closeness one remains to the location that is missed. This occurs when there is a positive bond to somewhere you have been and your efforts to return or the distance you keep in order to increase visits. Homesickness expresses the bond one may have for their homes after being away for long periods of time and their longing to return.
We may have personal connections to locations however, it can also be the people we were there with that grow our desire to return. Positive experiences with groups of individuals can draw out intense memories when looking back. Experiences can "create meaning". Something many of us have heard during the pandemic is "its not New York without New Yorkers," and I think this is true of many places right now. The energy that was once there is no longer. One important location I think students are missing is campus. A large part of university is the experiences and people you meet along the way. For some who live close, they can take a walk through campus but it is not the same without the constant energy from the student body. As for others who live further from their friends and school it can bring up emotions that cause one to reflect on happy memories.
However, school is certainly not the only place we could be longing for right now. Here are some suggestions to help you feel closer to your favourite place:
Homesick Candles
This is a company that sells candles with the scents of several different states and countries that you may be in desire to return to.
One of my favourite things to do while being home is to research some movies or shows that were filmed in the location I am missing. It is a lot of fun to watch and remember visiting the sights.
Look back on pictures you took when visiting last and FaceTime a friend to talk about the fun times and happy memories you made together.
Enjoy food that brings up nostalgic feelings.
Music is powerful and can have strong connections to moments in our lives. Refer back to what you were listening to when you last visited your favourite place.

Name shadowing in VHDL
Posted on 2015-01-26 by Philippe Faes
Like many other languages, it is possible in VHDL to perform name scoping. This happens if you declare a new object in a nested scope that reuses the name of an object that was already declared. This is not an error in VHDL, but it can be confusing and it can cause errors. In general, I would advice against name scoping unless you have a very good reason. Even then, it would be best if you document (comment) your code so that everybody understands what is going on.
This is a straightforward example of name shadowing:
entity e0 is
end entity e0;
architecture demo of e0 is
 constant c : integer := 1;
 assert c = 1;
 myblock : block
 constant c : integer := 2;
 assert c = 2 report "the second declaration of constant c shadows the first";
 end block myblock;
 assert c = 1 report "this is the scope of the first declaration again";
end architecture demo;
It gets more confusing if you shadow names from the a standardized package:
architecture demo2 of e0 is
 constant true : boolean := false; -- shadowing the name "true". Bad idea!
 assert false = true;
end architecture demo;
A common misconception is that loop iterators need to be declared beforehand. They don't, because they are declared implicitly in the loop statement.
architecture demo4 of e0 is
 process is
 variable i: integer := 1;
 assert i = 1;
 i := 5;
 assert i = 5;
 for i in 0 to 10 loop -- this is a different object, shadowing the variable i
 report integer'image(i);
 -- i behaves like a constant here
 i := i+1; -- error! cannot assign to constants!
 end loop;
 assert i = 5; -- this is still the variable, declared in the process
 i := i+1;
 assert i = 6;
 end process ;
end architecture;
Note: you can reach these shadowed names by using their expanded names:
entity fun is
end entity;
architecture hide of fun is
 example : process is
 variable x : integer := 0;
 procedure changevar (x : integer) is
 hide.example.x := x; -- or example.x
 end procedure;
 report "x=" & integer'image(x);
 end process;
end architecture;
VSIM 1> run -all
# ** Note: x=5
# Time: 0 ns Iteration: 0 Instance: /fun

Does Vinegar Kill Weeds to the Root?
Does Vinegar Kill Weeds to the Root?
Unfortunately, vinegar does not kill weeds to the root. While vinegar will degrade the biological material that weeds are made up of, this will typically only end up killing the leaves of older plants. That being said, there are some weeds that can be killed down to the root by vinegar.
In most cases, you'd be better off trying to kill younger weeds with vinegar, as seedlings tend to be less resilient than their fully-grown counterparts.
When you decide to start gardening, most people don't tell you about the many headaches that you can expect to experience while tending to your garden.
Pests are just the start of your issues, and it seems like once you finally manage to find a solution to them, you'll have to contend with an entirely different source of difficulties.
Weeds are the bane of any gardener or lawn-keeper. They make your garden or lawn look worse and they siphon crucial nutrients and water away from the plants that you actually want to see thriving.
Unfortunately, weeds are some hardy plants, and it can be tough to find a non-toxic way to deal with them.
In today's guide, we're going to take a look at one of these non-toxic methods, specifically, we're going to explore whether you can kill weeds to the root with vinegar.
We'll explore using different kinds of vinegar to kill weeds to the root and even take a look at some alternatives that you have available.
Does Vinegar Kill Weeds Permanently?
Theoretically, vinegar should be able to permanently kill weeds because it is a desiccant.
This means that it dries out the things that it touches, especially if it comes into contact with biological material like the cells that make up a plant.
The acetic acid in vinegar will gradually dry out each cell that it comes into contact with until the organism dies.
Most vinegars made for human consumption contain between 5% and 7% acetic acid, making them both safe to handle and environmentally friendly.
In theory, this means that you should be able to effectively kill any weeds in your yard or garden with a liberal application of your choice of vinegar.
Unfortunately, it doesn't ever quite work out this way because of how long vinegar lasts in soil. Since the acetic acid in vinegar will quickly wear away in soil, it won't be able to last long enough to do any lasting harm to the roots.
The very fact that acetic acid gets neutralized by soil is one of the main reasons why it's one of the most environmentally friendly weed killers.
The acid won't end up lingering long enough to do any lasting damage to any of the ecosystem, including other plants, pollinators like bees, and more.
To sum it up, the only kind of weed that you can expect tabletop vinegar to kill permanently is a seedling, as it won't have grown enough to be able to resist the vinegar enough to survive.

How Long Does it Take for Vinegar to Kill Weeds?
After preparing a spray bottle full of white vinegar to get some weeds out of your garden, you may be wondering exactly how much time you'll spend on the task.
The actual time you spend spraying the vinegar will be variable, as that will depend on the size of the yard that you're working on.
You'll start to see the leaves on the weeds drying out and dying away within the first few hours after you spray your solution on them. Hardier weeds may last a little longer before you start noticing the signs of them drying away.
In these cases, you may have to wait for up to 24 hours before you start seeing an effect.
Keep in mind that the yellowing and drying of the leaves doesn't necessarily mean that the weed is dead in the first place.
If you neglect to keep reapplying vinegar to the plant, then you'll notice that the plant will start getting healthier by the day until the leaves that were supposedly gone start growing back.
To keep the plant dead, come back to it every day and keep spraying it with vinegar on the days that you see the plant trying to sprout a new set of leaves.
Keep in mind that there's no guarantee that this method will kill the plant permanently, as you'll need to take out the roots to be truly effective.
What About 20% Vinegar?
So far, we've only discussed using tabletop vinegar to attack the root systems that are sustaining the weeds in your garden.
However, there is also horticultural vinegar, which is about four times more acidic than the kind of vinegar that we would normally consume. While using horticultural vinegar is safer than using commercial weed killers, it is still dangerous.
The vinegar that we put in our food is already highly acidic, but when the concentration of acetic acid in the vinegar reaches about 20%, it becomes nearly too dangerous to handle.
You certainly want to avoid using 20% vinegar if you don't have protective gear like goggles, gloves, and a long-sleeved shirt.
This is because 20% vinegar can cause chemical burns on contact with your skin. It being more powerful also makes it more effective at killing weeds down to the root.
Unfortunately, 20% vinegar won't work anywhere near as effectively as commercial weed killers because of how easily it disperses.
Even large amounts of 20% vinegar in your soil will likely not get to the root of the weeds that are plaguing you, so this is not as reliable of a method as you may expect it to be.
Also, be wary of getting 20% vinegar on any of your tools, as it can corrode metal, wood, and even concrete.
Does Apple Cider Vinegar Kill Weeds?
If 20% vinegar doesn't do the trick, maybe apple cider vinegar will. Apple cider vinegar has been touted in recent years for its healthy properties, but can it also be a versatile enough tool to see use in your garden?
Considering apple cider vinegar tends to contain between 5% and 6% acetic acid, it's a little on the weak side.
Compared to other kinds of vinegar that you may have available in the pantry, apple cider vinegar isn't much more or less effective because of its similar acetic acid levels.
Much like other kinds of vinegar, the most you can expect from apple cider vinegar is to kill the plant's leaves.
You can expect to wait for about a day for apple cider vinegar to kill the leaves on a plant, but you may see new leaves sprouting out within the next few days after that.
As with any other weed-killing method, you have to either kill or remove the root to make your efforts permanent.
Does Vinegar, Epsom Salt, and Dawn Dish Soap Really Kill Weeds?
Epsom salt is one of the most effective ways to kill any type of plant because of how it sucks the moisture out of the surrounding soil.
However, there's a reason that "salt the earth" has become a relatively common saying since it's very unlikely that anything will grow on salted soil for a long time to come.
Mixing salt into vinegar and dawn dish soap will make for an effective weed killer, but it will also kill anything else that you try to plant in that bit of land.
Salt is so insidious in soil because it doesn't take effect instantly, so you may not know the extent of the damage you caused until it's too late.
By the time ten days have gone by, the salt will have made its way into the earth, making it impossible for anything else to grow there, though it will also have killed any existing weeds.
Unlike vinegar, salt also won't be neutralized over time, making that plot of land a dead zone for years to come.
What Kills Grass and Weeds Permanently?
If you're looking to get rid of the weeds in your yard or garden permanently, then you may not be satisfied with the performance of vinegar, despite its safety and eco-friendliness.
Unfortunately, if vinegar was such a convenient way to kill weeds, everyone would be doing it by now.
Instead, due to the relative ineffectiveness of vinegar, gardeners tend to resort to chemical weed killers which can penetrate deep into the root system and destroy the weeds from within.
The downside to this approach is that you may end up damaging other plants in the area and even potentially rendering them toxic, based on the weed killer formula that you're using.
If you don't like the idea of potentially poisoning all of your other plants while trying to kill some weeds, then you can start killing weeds the old-fashioned way: by uprooting them.
While pulling weeds out by their roots may be a bit more challenging than just pouring something on them, it's a much safer alternative to using chemical weed killers.

Difference Between Epidemic and Pandemic
Difference Between Epidemic and Pandemic
Both epidemics and pandemics are words that are used to describe the widespread of diseases.
What is an Epidemic?
An Epidemic is generally defined as the process of rapidly spreading of infectious diseases within a short period of time into a large number of people in a given population and spread over to several countries or continent.
An Epidemic is derived from a Greek word which refers to upon or above people.
Bubonic plague, Cholera, Influenza, SARSand Smallpox, are some of the common examples of Epidemics.
Also Refer: Symptoms of Various Diseases
What is Pandemic?
A pandemic is the worldwide spread of a new disease. A pandemic is a larger version of an epidemic. In other words, when an epidemic goes out of control, it is known as a pandemic. If an epidemic covers many countries spreading through continents, it is likely to be a pandemic. There are different types of pandemics.
HIV or AIDS is one of the best examples for the most destructive global pandemics in history.
The main causes of Epidemic and Pandemic are the pathogenic or harmful microorganisms, such as bacteria, viruses and other parasites that can spread, directly or indirectly, from one person to another through the air, water, and other modes of transmissions.
Also Refer: Communicable and Non Communicable Diseases
Let us look at the differences between epidemic and pandemic given in a tabular column below to understand both these terms in-depth.
Epidemic vs Pandemic
An epidemic is an outbreak of disease that affects many in a population and begins to spread rapidly.Pandemic is a larger epidemic. A pandemic covers several countries or spreads from one continent to another.
An outbreak of disease is considered an epidemic if it affects a certain number of people within a short period of time, typically within 2 weeks.In pandemic outbreaks, the number of people affected or killed doesn't matter as much as the rate of spread and how far it has spread.
One of the few examples of epidemic diseases is the West African EbolaA few examples of pandemic diseases are HIV AIDS, Asian Influenza and Cholera

How to Hold Focus Mitts & Pads: Top Tips
There's no denying that focus mitts are an essential part of any fighters training regime.
The only issue is, they require someone else to hold them.
Not only that, the person holding the mitts needs to have a good knowledge of different combinations and where they should be holding the mitts for each combo.
A good focus mitt session is only as good as the person holding the mitts, and with that in mind, we've put together this guide o how to hold focus mitts.
We're going to cover some tips you can implement into your training, go over some useful combinations and share some valuable resources as well.
Let's get to it.
Benefits of Focus Mitts
Before we get into our top tips, let's first analyse the benefits that using focus mitts has to offer.
Work on Distance & Timing
Focus mitt work allows the person training to work on their distance and timing, which can't really be done on equipment such as a heavy bag.
By using focus mitts, you're much able to somewhat simulate a fight scenario, where the person training must move around, gage the distance and react to the pad mans commands.
Train Both Offensive & Defensive Technique
One of the main benefits of focus mitt's is how they allow the fighter to train both their offensive and defensive game. They can practice throwing a combination, slipping a counter and returning with another combination.
This can't really be done with any other equipment, especially to this sort of level.
Practice Movement
Focus mitt work allows the person training to practice working different angles, get comfortable coming in and out of range and develop their footwork.
With the exception of sparring, very few other training exercises provide such a well rounded practice, especially where movement is concerned.
Simulate a Fight, Round by Round
If a fighter is training for an upcoming fight, focus mitts can be a great way to keep their senses sharp, without having to spar.
You can even set the timer to however many rounds their upcoming fight is, and work the pads for that amount of time. This way, they'll be able to develop their endurance so that they can maintain a certain level of output throughout their fight.
How to Hold Focus Mitts: Top Tips
Right, let's dive into some of our top tips for holding focus mitts.
Also, if you haven't already got yourself a decent pair, head over and check out our guide on the best focus mitts for some fantastic options.
Tip 1: Positioning
First things first, is for the pad man (or women) to have their positioning correct - both in terms of how they're stood and where they're holding the mitts.
I've seen a lot of people in the gym holding the mitts way too far out to the side. As a general rule of thumb, keep your elbows close to your body. If you're holding the mitts out like chicken wings, bring them elbows in much, much closer.
Tip 2: Arm & Wrist Tension
When you're holding the mitts for the person training, make sure to keep your arm and wrist somewhat tensed. You don't want your wrist to be snapping back every time the person hits the mitt. Keep your wrists and elbows firm throughout the exercise.
Tip 3: Hand Movement
In terms of hand movement, it's important to find the right balance. You don't want to keep your hands raised and still the whole time, nor do you want to be overly swinging the mitts towards the persons glove.
Lightly bring the mitt towards the persons gloves - don't extend too far though, as you want the person training to practice finding the correct distance and find the pad themselves (move the pad around an inch or two).
Similarly, don't keep your hands raised the entire time like a tree. Instead, drop your hands to your waist in between each combination. This way, the person training has to react to your movement.
Tip 4: Remind Them to Keep Their Hands Raised
The whole point of pad work is to help keep the fighter sharp, fast and maintaining their technique. As such, it's your duty as the pad man to prevent them from picking up any bad habits and keep their technique in shape.
For example, if the person training is dropping their hands, make sure you let them know. Throw a cheeky jab to their head (lightly), just to let them know if this was a real opponent, they'd have been hit.
Tip 5: Don't Always Call Out the Combinations
You can also do something that's known as target practice. This is where you don't call out the combinations, just put the mitts up and let the fighter react to what they see.
This can help to get them used to throwing strikes and combinations out of instinct, as opposed to being told what to do. I would do this alongside regular pad work, maybe for the last round, once they've found their rhythm and have an idea what sort of combinations are going to be coming.
Tip 6: Remember to Move Around
If you've got space, use it.
A real fight isn't going to consist of two fighters planting their feet and banging it out (well it's unlikely). Remember to circle around the person training, so that they have to follow you in order to stay in front and land their combinations.
What's more, this movement will allow them to practice working different angles, and using their footwork to stay in range.
Tip 7: Increase Speed
As your training partner is starting to land the combinations comfortably, start to pick up the pace.
This in turn will help to improve their hand speed as well as their endurance.
Tip 8: Throw Your Own Strikes
In an actual boxing match, or any combat sports match for that matter, the person opposite you is going to be fighting back.
With that in mind, you as the pad holder should throw some of your own strikes into the mix, forcing the person training to slip or roll out of the way.
You can work these nice into the combinations, for example jab, cross, hook, slip, jab, cross, hook.
Example Combinations
If you're finding it hard to know which combination to call out, the below video is a fantastic example.
I absolutely love this video from precision boxing, as it literally shows you how to hold the pads for different combinations.
It also starts off nice and simple, then starts to incorporate some more advanced combinations as the video progresses.
Check it out below.
Final Thoughts
Thanks for taking the time to read our guide on how to hold focus mitts.

ZeFamily Legacy of Brioche Pasquier
ZeBot & ZoeBot Have Breakfast at Brioche Pasquier"When someone shares a special family recipe with you, you become part of their family."
That's what my friend Hugues Pasquier told me when we shared a breakfast made with the brioche his family has been baking from the same recipe since 1936.
It was true: as my cousin ZoeBot and I savored each buttery golden bite, we felt the Pasquier family's culinary heritage deep in our stripes.
If you're an average American kid (or zebra), you may not have ever tried brioche. But in France, kids (and a few lucky zebras) have been eating brioche their whole lives.
Brioche (pronounced bree-oshe) is a French bakery specialty that looks and tastes like a magical cross between a bread and a cake.
Brioche by Chardin, 1763
Food historians say that's it been a tradition since medieval times, with the recipe becoming richer with butter and eggs as the centuries passed.
Hugues told us that his grandfather Gabriel Pasquier was legendary for the brioche he crafted at his bakery in the tiny village of Les Cerqueux in France's Loire River Valley.
Gabriel's Bakery
Gabriel's recipe was unique because he always used two very special ingredients.
One was the family's own levain, which is a natural sourdough starter that makes brioche (and other baked goods) rise. A starter works pretty much the same way modern yeast does, but it's an older and more traditional way to leaven baked goods. Continue reading


Recall that the reflections {s_{\alpha} \in Aut(E)} for {\alpha \in \Phi} preserve {\Phi}. They generate a group {W} called the Weyl group. Moreover, since {\Phi} spans {E}, the map {W \rightarrow S_{\Phi}}, the symmetric group on {\Phi}, is injective. So {W} is a finite group of orthogonal isomorphisms of {E}, i.e. leaving invariant the bilinear form {(\cdot, \cdot)}.
Everything here actually makes sense for root systems in general, but we are restricting ourselves to the case of a root system associated to semisimple Lie algebra and a Cartan subalgebra. The only difference is that one has to prove the result on maximal strings (which was proved in the case of Lie algebras here), though it can be done for root systems in general.
Now choose a base {\Delta} for {\Phi} and a corresponding partition {\Phi = \Phi^+ \cup \Phi^-}; the {s_{\delta}} for {\delta \in \Delta} are called simple reflections.
The goal we are aiming for is the following theorem, which gives a large amount of information about the Weyl group.
Theorem 1 {W} acts simply transitively on Weyl chambers and on bases. Any root can be moved by an element of the Weyl group into a given base. {W} is generated by the simple reflections. (more…)
So, suppose given a root system {\Phi} in a euclidean space {E}, which arises from a semisimple Lie algebra and a Cartan subalgebra as before. The first goal of this post is to discuss the "splitting"
\displaystyle \Phi = \Phi^+ \cup \Phi^-
(disjoint union) in a particular way, into positive and negative roots, and the basis decomposition into simple roots. Here {\Phi^- = - \Phi^+}.
To do this, choose {v \in E} such that {(v, \alpha) \neq 0} for {\alpha \in \Phi}. Then define {\Phi^+} to be those roots {\alpha} with {(v,\alpha)>0} and {\Phi^-} those with {(v,\alpha) < 0}. This was easy. We talked about positive and negative roots before using a real-valued linear functional, which here is given by an inner product anyway.
OK. Next, I claim it is possible to choose a linearly independent set {\Delta \subset \Phi^+} such that every root is a combination
\displaystyle \alpha = \sum k_i \delta_i, \quad \delta_i \in \Delta, \ k_i \in \mathbb{Z}
with all the {k_i \geq 0} or all the {k_i \leq 0}.
Then {\Delta} will be called a base. It is not unique, but I will show how to construct this below. (more…)
