A Walker's journey
You can follow William Walker's journey at _URL_.
It just makes sense; Carpenters build, Painters paint, Millers mill, a Carver carves, and, a Walker walks. Eventually, we all learn the meaning of our last name. It is guarded, handed down, revered, respected, and for some it bears witness for a pilgrim to embark on a pilgrimage.
Such is the case for 33-year-old William Timothy Walker of Canada. Actually, William wasn't always called William; he went by his middle name, Timothy, until the fall of this year when he had a powerful dream and he interpreted that he must not only use his first name, but also honor his name, William Walker, by doing as his forefather from Orange County did, and walk.
It was 219 years ago, in 1793, that William Walker walked from Orange County to Lincoln County, Ontario, a distance of more than 1,000 miles.
Walker researched and found that his forefather actually walked the journey three times: the first to settle land, the second back to Orange County, and the third to lead his family of nine children, wife, and cattle to land granted by the Royal Government.
According to Walker, his forefather served under Lord Cornwallis and pledged his allegiance when in Canada and was granted 1,200 acres of land on Lake Ontario.
"I'm the ninth William Walker in a long line of Walkers and I feel it is my rite of passage," Walker said the evening before his journey. Walker and his father, William Wilfred Walker, began exploring Orange County to retrace the lineage of their families. They began at the tourist bureau for Orange County, were directed to the farmers' market where they met a Walker who turned out not to be of their family, but this Walker directed these Walkers to Norman and John Thomas Walker of Caldwell.
It was here that the Walkers of Canada united with the Walkers of Caldwell and they began to explore the roots of a very old family tree. According to the Walker family, the earliest Walkers were from Ireland and settled this area in the early 1700s.
Near the intersection of Kiger Road and Norman's Road in Caldwell, the Walker family cemetery sits, along with one of the original homes that was built on this land. It was here on Monday that William Timothy Walker stood by the tombstones of his descendants and he inhaled the first breaths of what he calls a pilgrimage.
The setting is something of history. It is foggy, damp and it is mild for December. There are horses in the pasture and it is quiet and William Thomas is standing somewhere near where a forefather stood, upon deciding to walk to Canada.
On this hallowed ground for Walkers, history and rite of passage and a quest to know the path in life and the purpose of life, was about to begin, through the determination, will, and legs of a 33-year-old from Canada.
"My pack will weigh about 40 pounds and all that I will need is contained in this pack," said William.
From Caldwell, William would journey to Highway 86 North and then to Danville, Va., to Roanoke, Va., and eventually to the Appalachian Trail, where he would course to the north, through Pennsylvania and to Buffalo, N.Y., and ending his journey at Walker Hall, the homestead his forefather built in Canada.
"I have two changes of clothes and will eat high energy meals, mostly made from powders and such. I have two propane tanks to power my stove and for the most part I will camp and stay on the trail," William said. According to his father, William is an experienced camper. "He camped in Cambodia and has traveled the world. Though I am concerned as a parent, I trust he will be all right and I trust his ability to do this," Walker said.
The day before William left for Canada, he attended services at Little River Presbyterian Church, where he stood in the shadows of other tombstones. There are Walkers buried here and descendants and young William Walker is surrounded by cousins, of various ranks, and all are inquisitive about why a man would want to walk from here to there.
"We think they left in early spring and arrived the summer. Along the way cattle died, but he and his family arrived to a new beginning and established home and a life in Canada. Of being a Walker, I think it is about finding your way. It is about trusting and knowing what to do that is right and to connect in that in a visceral sense is really amazing," Walker says.
According to Walker, he hopes to average about 40 miles per day and he planned for the trip to take about one month. Time will tell if Walker accomplishes his pace and how much of a factor the weather will play as he journeys from the mild South to the harshness of winter's North. He will be alone. He will be cold. He will be hungry. He will go days without another human to hear his words or to look upon his face. He will struggle. He will encounter challenges and eventually, the propane that fuels his stove will run low and he will have to enter a town to gather provisions.
Two hundred years ago, his forefather set forth on a similar journey and he did so for reasons that are personal and he did so because of the man he was. He was also a Walker. And, for William Timothy Walker and all of the Walkers in his family and the Walkers that will follow and the Walkers that are yet to be known or born, this William Walker will walk this pilgrimage because of his name. Somewhere between here and Canada, a man is walking because he is a Walker. It is, as it has been since the 1700s, a Walker's journey.

How Do We Read? More specifically, how does the brain recognize letters? Pattern Recognition How does pattern recognition in the brain work? Could a mathematical or computer model be built to emulate the way the brain recognizes letters?
Critical Point Theory Critical point theory is the theory our group is testing It states that brain recognizes how lines in letters intersect, and stores representations of these "critical points" When you see a letter, your brain compares the critical points to stored critical point patterns to identify the letter
Major Questions Is this theory valid? If it is, how powerful is it? Can we create a mathematical model that can be used to accurately predict how difficult it is to read a letter? Aside from critical point theory parameters, what other parameters would be useful to have in such a model?
The Letter Sets 50 letters were drawn using an image editor Ten were control, and were normal letters Ten had critical points covered by "paint" Ten were covered by "paint," but the critical points were left uncovered Ten had the critical point relative orientation "bent" Ten letters were bent, but the critical point relative orientation was unchanged
The Experiment People were shown these letters, and asked to name the letters Response time, in seconds, was recorded by the experimenter They were told explicitly that they don't need to mention the case of the letter Sample Critically Occluded Letter
Data Divided into Two Analyses Occlusion Bend Dependent Variable Response Time Explanatory Variables Occlusion Type Percent Occlusion Frequency Position Points Occluded Dependent Variable Response Time Explanatory Variable Bend Type
Occlusion Set Analysis Through ANOVA, it was found that occlusion type was indeed a significant predictor of response time Through ANCOVA, it was shown that differences in occlusion percentage between occlusion types did not falsely suggest that the occlusion types were different Through visual inspection and ANCOVA, it was shown that critically occluded points had overall higher reaction times than noncritically occluded points A final model was derived through stepwise regression Due to a lack of low occlusion percentage representation, occlusion percentage had an insignificant, negative "nonsense" coefficient, and was removed
Bend Set Analysis Unfortunately, we couldn't devise a method of quantifying how bent a letter is in comparison to an unbent version of the same letter. Do you have any ideas as to how we could do this? Through ANOVA it was shown that bend type was a significant factor in predicting response time
Results It was demonstrated that our critical point theory has statistical support Although the model created is poor, from the outset this study was intended to be an initial, exploratory study The study suffered somewhat from lack of difference across administrations of the experiment If this was to be followed up, it would benefit from computergeneration of unique experiments Overall, the theory was demonstrated to show real evidence of validity. It is safe to call the study a success
The frequency data used in this experiment was taken from an online source. A formal citation is available upon written request to Jeff Cochran, and will be included in the Project Part II write-up.

Hi i m using given below method to convert in to string its working fine chrome but in IE its through exception Input string was not in a correct format. at this line

2 Answers 2
The failure is probably in the call Convert.ToDouble. Your code probably executes in a CultureInfo that has ',' as decimal separator, but your values use '.'. I would advice you to use Double.TryParse using a CultureInfo that has '.' as decimal separator instead:
Double value;
if (Double.TryParse(time, NumberStyles.Any, CultureInfo.GetCultureInfo("en-US"), out value))
 s = TimeSpan.FromSeconds(value);
share|improve this answer
You need to specify an IFormatProvider when you use Convert.ToDouble(time):
Convert.ToDouble(time, CultureInfo.InvariantCulture)
Specifying CulturInfo.InvariantCulture specifies a culture that expect floating points written as 1.234 (note the period). The source of your problem may be that you time is in the format 1,234 (note the comma). Or maybe it is the reverse: You don't specify an IFormatProvider and the current culture of you ASP.NET process uses comma as a decimal separator, but the string provided uses period?
If the decimal point used isn't consistent you should either fix it at the source (not sure what the source is here) or as a last resort you can replace comma by period:
Convert.ToDouble(time.Replace(",", "."), CultureInfo.InvariantCulture)
However, trying to parse a string and not knowing the what to expect is not the best thing to do.

Your Answer


Problem Description
"HOR!! You want jacket or you want me ><" Rar the Cat asks.
"Me jacket" His beloved girlfriend answers.
Rar the Cat is devastated. Really? Does a jacket have more worth than him? Determined to find out the true answer, Rar the Cat sneaks into his girlfriend's house during her sleep, and records down everything she says in her sleep, to determine her true thoughts. However, due to his horrible note-taking skills, he is only able to take down a long string of upper-case letters! Help Rar the Cat figure out his worth by counting the number of times "RANALD" and "JACKET" appears in the string of letters. If there are more "JACKET"s than "RANALD"s, output "JACKET" to indicate that the jacket is more important. Else, output "RANALD".
The input will consist of one upper-case string, the one that Rar the Cat took down.
Your output should be either "JACKET" or "RANALD", according the number of times it appears in the long string.
Subtask 1 (30%): Length of string will always be less than 1,000 characters.
Subtask 2 (70%): Length of string will always be less than 10,000,000 characters.

Cloud Discovery data anonymization
Cloud Discovery data anonymization enables you to protect user privacy. Once the data log is uploaded to the Cloud App Security portal, the log is sanitized and all username information is replaced with encrypted usernames. This way, all cloud activities are kept anonymous. When necessary, for a specific security investigation (for example, due to a security breach or suspicious user activity), admins can resolve the real username. If an admin has a reason to suspect a specific user, he can also look up the encrypted username of a known username, and then start investigating using the encrypted username. Each username conversion is audited in the portal's Governance log.
- No private information is stored or displayed. Only encrypted information.
- Private data is encrypted using AES-128 with a dedicated key per tenant.
- Resolving usernames is performed ad-hoc, per-username by deciphering a given encrypted username.
How data anonymization works:
There are three ways to apply data anonymization:
You can set the data from a specific log file to be anonymized, by creating a new snapshot report and selecting Anonymize private information.
You can set the data from an automated upload for a new data source to be anonymized by selecting Anonymize private information when you add the new data source.
You can set the default in Cloud App Security to anonymize all data from both snapshot reports from uploaded log files and continuous reports from log collectors as follows:
Under the Settings cog, select Cloud Discovery settings.
In the Anonymization tab, to anonymize usernames by default, select Anonymize private information by default in new reports and data sources.
Under Encryption key, select whether you want to Use the dedicated key generated for your portal or Use a custom key. If you Use a custom key, enter a 16-byte UTF8 encryption key.
- Click Save.
When anonymization is selected, Cloud App Security parses the traffic log and extracts specific data attributes.
- Cloud App Security replaces the username with an encrypted username.
It then analyzes cloud usage data and generates Cloud Discovery reports based on the anonymized data.
For specific investigation, such as investigation of an anomalous usage alert, you can resolve the specific username in the portal and provide a business justification. This page can also be used to look up the encrypted username of a known username.
- Under the Settings cog, select Cloud Discovery settings.
- In the Anonymization tab, under Anonymize and resolve usernames enter a justification for why you are performing the resolution.
- Under Enter username to resolve, select From anonymized and enter the anonymized username, or select To anonymized and enter the original username to resolve. Click Resolve.
The action is audited in the portal's Governance log.


The term "Factories" comes from the factory design pattern. Factories are objects which can create new instances of certain types of Entities. Factories provide the following benefits:
 1. Entities created in a factory will automatically be added to screen lists (by default).
 2. Factories provide a standard way to create entities which is especially useful for systems like Tiled to instantiate new entities.
 3. Factories can pool Entities which can greatly reduce allocated memory for Entities which are created and destroyed frequently.
If your game requires the creation of entities in code (such as the player shooting bullets or enemies appearing at an enemy spawn point), then you will want to use factories.
Quick Usage Example
To use a factory in Glue:
 1. Create or select an existing entity
 2. Select the Quick Action tab
 3. Click the Add Player Factory button. Your button may have a different text matching your selected Entity's name.
 1. If you do not see this, your entity may already have a factory. To check this, look at the properties tab for your entity and find the Created by Other Entities property. If it's true, you already have a factory.
 4. Click Add Player List to GameScreen. Note that if your main screen is not titled GameScreen, then you will need to manually add a list to the desired screen. A screen must exist in your current screen or the created entities will not have their CustomActivity methods called.
 5. In any code, such as in GameScreen or any other entity, create a Player instance using the CreateNew method as shown in the following code:
 void CustomInitialize()
 var player = Factories.PlayerFactory.CreateNew(x: 50, y: 100);
 // perform any additional modifications to the player here
For a tutorial on how to use factories, see the Created by Other Entities tutorial page.
Factories Generated by Glue
Glue will automatically generate factories for any entity which has its Created by Other Entities property set to true.
For information on this property, see the CreatedByOtherEntities page.

Why journalists should burn dishonest sources
Journalists have a duty to expose anonymous sources who knowingly deceive them. Anonymity is a quid pro quo, and ethical journalists only offer it in exchange for valuable information that they can't get any other way.
The promise of anonymity shouldn't be absolute. Anonymous sourcing sacrifices some transparency for the sake of important information. A source who knowingly peddles forgeries under the cover of anonymity is abusing the reporter's trust and the trust of his or her readers. That kind of behavior must have consequences.
The best remedy is to reveal the identity of the person who passed off the fraudulent information in bad faith. The only reason we tolerate anonymous sources is to get good information. By practicing deception under the cover of anonymity, dishonest informants thereby undermine whatever justification the reporter had for granting anonymity in the first place.
The public has a right to know who's shopping bogus stories to the press. We also have a right to know who duped the reporter in question. Granting anonymity is a journalistic judgement call. When a source turns out to be a fraud, we need to know who that source was so that we can assess whether the journalist granted anonymity responsibly. If it turns out that the reporter has been granting anonymity frivolously, or to blatantly untrustworthy sources, he or she shouldn't be allowed to simply blame the anonymous source and move on.
For example, it makes a big difference who Jason Zengerle of the New Republic was dealing with. If we don't know the identity of the informant who forwarded Zengerle the partially fabricated email, we have no way of knowing whether Zengerle was honestly duped or whether he was using anonymity to conceal the dubious quality of his source.
The policy of burning deliberately deceptive anonymous sources should be enforced at the editorial level. Once deception and bad faith have been established, it shouldn't be the reporter's decision. If, after consulting with the reporter, an editor is convinced that a source was deliberately deceptive, the source's identity should be revealed as a matter of institutional policy.
Anonymous sourcing is a necessary evil. Enforcing consequences for those who abuse a reporter's trust will improve the quality of anonymous sourcing overall.

Lindsay, you're making way too much sense for the goofy-ass world we live in.
Obligatory O/T aside: I love the new pic. You should be playing guitar in an indie band. Assuming you're not doing that already.
Burning your source if they lie to you may seem like a fair trade off ethically to some, but I'd say that stance is unrealistic at best. When an anonymous source gets outed, all people remember is that the reporter betrayed the source... the reason... while it may even be a good and ethical one, is not something future sources are likely to care about.
Bear in mind, if you're an anonymous rat, you're probably doing questionable things all the time, as it is. So if you can't trust the certainty of the 'protection' when it comes to a certain reporter, you simply go elsewhere. Not burning a bad source actually increases a reporter's value to other sources who might be spreading bad info with the good, knowingly or unknowingly.
Also, now this source owes the reporter he gave bad information to, big time. Information flow, long term, is sometimes more important than one embarrassing story.
Information bartering, like any kind of trade, can be a sleazy business, even for those with high ideals.
Although I don't disagree with the feeling here, hang the fucker, I just don't think its so cut and dry in the real world. This is much the way I feel about the 'death penalty' actually, some people deserve to die, in my opinion, but the cost to society of actually killing people, for 'justice', seems too high. The cost of burning the source maybe have been in this case aswell.
Oh, and glad you kept the Cash.
I generally agree, but it may not be entirely practical for a reporter, especially on a sensitive beats where a reporter is continually talking to people off the record...
If you get a reputation for someone who will burn an anonymous source who trucked in misinformation, then just about anyone who might be willing to speak on condition of anonymity might be shy.
For myself, it was always a matter of whether I felt the mis-/dis-information was deliberate or not.
That said, if someone deliberately fed me something wrong with the belief that I was going to print it, then fsck 'em... they get spaced out the airlock...
mojo sends
The problem is "everything" these days has "value"... including access to information. The access to power makes reporters goofy to say the least.
But when someone wants anonymity and then lies or gives you bogus information... that source... and that is a generous word... should be outed.
The idea that information has to be fed in secret, back channels and "on background" from a anonymous source is so bogus. Why the stealth?
Can't we have a little light in the world? Just a little...
Is there any extended justification for using anonymous sources. Reporters always say 'we need anonymous sources', but why do we take there word for it?
There is a great Ph.D. out there for someone on epistemology and journalistic methods.
If I knew a secret that I wanted to give to the press, and I wanted anonymity, I would be very wary of dealing with a reporter who played by your rules.
Why should I trust his judgement on what is or isn't the truth? If he's so worried that I'll fool him with a lie, shouldn't I be worried that someone else will fool him into thinking I lied?
(P.S. I like the new picture much better too.)
Vanmojo made a good point earlier in this thread, namely, that journalists should only burn their sources if they and their editors are convinced that the source knowingly misled the reporter. In practice, it's often difficult to establish deliberate deception. I'm not saying that reporters should burn every anonymous source whose story doesn't pan out. However, when you know that a source lied to you, you have a responsibility to expose them. Maybe that will deter some people from coming forward, but the policy is much more likely to defer fakers than honest people.
People get things wrong.
Short of being reasonably certain that one is being "used" to propagate garbage, I suspect abstract moral points won't cut much ice with a crowd told you've broken confidence.
I agree with Windypundit: it's not that hard to mount a concerted campaign to discredit a source. It all depends on how tightly knit the community doing the discrediting is (e.g. I don't think the people on the Townhouse mailing list could do it), and on how far the people are willing to go to protect their dirty secrets.
So to prevent that pathology from destroying whistleblowers, you can relax your rule and say that it depends on the source's reputation: a source that repeatedly gets things right gets more slack after one infraction than a new source or a source that gets things wrong several times. Alternatively, you can require that journalists identify their sources at least by alias, so that readers will know e.g. that Deep Throat is always the same person.
Oh, I'm glad that everyone is cautioning Ms. Beyerstein on how burning blatantly mendacious sources would have a chilling effect on legitimate sources coming forward. Someone passed Mr. Zengerle a deliberately forged piece of information. This is not some convoluted moral calculus at work here. God, what a chilling effect it would have on anonymous sources if they didn't feel free to make shit up with no consequences. Likewise, Ms. Miller's sources weren't trying heroically to get the truth out, they were deliberately shoveling the administration's bullshit. When objective reality turns out to conflict with what your sacred "anonymous source" has been feeding you, you burn them. Sure, a source can be wrongfully discredited. Look at how Richard Clarke was beaten up by anonymous White House sources lying about him in the press. Oh, wait, bad example. Yes, we need to avoid "jumping the gun" just because a source passed on a rumour that didn't pan out. But don't tell me that it's impossible to tell the difference between that and deliberate falsehoods being peddled to destroy someone else's reputation.
So yeah, outing demonstrable liars will put such a damper on genuine whistle blowers. Unlike, say, the President of the United States throwing a tantrum on the TV about how journalists should be punished for thinking we still have a Bill of Rights.
Ther trouble is that the source may be making an honest error. If Zengerle's source passed on information from a third party believing it was true, burning the source does nothing to advance good journalism. You cloud argue that publishing material that's second hand is de facto bad journalism (and I'd accept that argument), but there's enough wiggle room there that a potential source may well be reluctant to talk on the off chance that an error or miscommunication would result in outing and the potential career destruction that comes with it.
In practice, source burning is rare because it's difficult to establish with certainty that a source deliberately lied. Journalists and editors don't like burning sources. As some of the working reporters on this thread have pointed out, nobody wants that kind of reputation

PRICKLY PEAR (TUNA)
'Prickly pear' is the common name of the fruit that grows at the tops of the leaves of Nopales cacti. The fruits are oval in shape, and can range in color from yellow and light green to orange, pink, and red, depending on the variety and ripeness. Apart from the unusual name, appearance, and origins of this fruit, it also has a very unique composition of nutrients, including high levels of vitamin C, B-family vitamins,magnesium, potassium, calcium, copper, and dietary fiber. In terms of organic compounds, prickly pears have high levels of flavonoids, polyphenols, and betalains, all of which have a positive impact on human health.
Some preliminary evidence shows that prickly pear cactus can decrease blood sugar levels in people with type 2 diabetes. Research also suggests that prickly pear cactus extract may lessen the unpleasant effects of a hangover. Prickly pear cactus is popular in many areas of the world, because it's high in fiber, antioxidants and carotenoids.
The edible parts are the leaves, flowers, stems and fruit. Prickly pear cactus is eaten whole (boiled or grilled). It is also made into juice and jams. The fruit can be eaten fresh.
Some of the health benefits of prickly pear include its ability to lower cholesterol levels, improve the digestive process, decrease the risk of diabetes, boost the immune system, stimulate bone growth, strengthen blood vessels, prevent certain cancer, reduce the risk of Alzheimer's, aid in weight loss attempts, and eliminate inflammation throughout the body.
If you'd like to try prickly pear cactus, consider easing into it. Side effects for some people include mild diarrhea, nausea, increased stool volume, increased stool frequency and abdominal fullness.


A Nepali film based on survivors' accounts of alleged systematic torture and disappearances during the country's civil war which ended in 2006 has been banned following objections from the army.
Badhshala, meaning "Slaughterhouse," records the military's well-documented record of human rights abuses during the conflict.
The ten-year civil war claimed more than 16,000 lives, with 1,400 people remaining "disappeared".
The army says that the film might harm the peace process but critics say the ban reveals censorship, intimidation and a reluctance to confront the past.

What does BUTO mean?
Buto, Butus, or Butosus, now Tell al-Fara'in near the city of Desouk, was an ancient city located 95 km east of Alexandria in the Nile Delta of Egypt. The city stood on the Sebennytic arm of the Nile, near its mouth, and on the southern shore of the Butic Lake. It is the modern Kem Kasir. Buto originally was two cities, Pe and Dep, which merged into one city that the Egyptians named Per-Wadjet. The goddess Wadjet was its local goddess, often represented as a cobra, and she was considered the patron deity of Lower Egypt. Her oracle was located in her renowned temple in that city. An annual festival held in the city celebrated Wadjet. Her image formed the royal crown, the Uraeus, worn by the rulers of Lower Egypt. It encircled their heads and the cobra flare and head extended from their foreheads. Wadjet was closely associated in the Egyptian pantheon with Bast the fierce goddess depicted as a lioness warrior and protector, a sun goddess whose eye later became the eye of Horus or the eye of Ra, the Lady of Flame. The city also contained a sanctuary of Horus and much later, became associated with Isis.

by sign "±".
Equation 24 gives (LB/GB)max only when the "
±" sign preceding its second term holds. This is so because of the following reasoning.
Let us draw a generic equilibrium curve for the full range of X, positive and negative values of X (Fig. 2). Also the point Y1, X1, corresponding to the dilute bottom of the stripper tower is indicated. Eqn. 24 gives the two possible points, "A" and "B", where the tangents lines passing through Y1, X1 can touch the generic equilibrium line. Since it should hold XM >X1 it is obvious that only the steeper slope of the two straight lines, in Fig. 2, is possible and this steeper slope can only be attained if the "+" sign, before the second term in Eqn. 24, is considered as valid.
An additional demonstration to the fact that Eqn. 24, with the "+" sign before its second term, gives the correct molar ratio (LB/GB)max, is given in the Appendix.
Example 1.
The design of stripper section of Illustration 8.2 in (Treybal, 1980) is taken as an example for the application of the solution given by Eqn. 24, in this Note.
Benzene is to be stripped from a wash oil by superheated steam injection at atmospheric pressure and 122oC. The debenzolized oil of 0.005 mole fraction, in benzene, is to be cooled to 26oC and returned to an absorber. The stripper temperature is constant at 122oC. Other data are that Henry's law applies with H= 3.16. Also:
X2 = 0.119; LB = 1.787x10-3 kgmol/s;
Y1 = 0.0; X1 =0.005/ (1-0.005) = 0.00502
The application of the solution given by Eqn. 24, with the "+" sign preceding its second term, gives:
This result agrees with that given by (Treybal, 1980) with 0.24% error.
While the solution given by (Treybal, 1980) requires making a Y,X plot to obtain the tangent to the equilibrium curve, the use of the solution given by Eqn. 24 saves time and gives a result less subject to error.
Example 2
Hexane contained in a residual oil is to be stripped with nitrogen at 100oC and one atma. Content of hexane vapor at the inlet of the gas stream is 1% v/v. Other data are:
H=1.6; LB =0.021 kgmol/s; X2 = 0.517; X1 = 0.0293; Y1 = 0.0101
The application of the analytical solution (24) gives:
The result obtained from Fig. 3 by means of the graphical procedure is (GB)min = 0.0102 kgmol/s, in good agreement with the mathematical answer.
Figure 3: Graphical Procedure for Example 2
An analytical expression was obtained which allows us to calculate the minimum gas flow rates of isothermal gas strippers when Henry's law applies (H>1).This expression may replace the graphical procedure currently used, providing an accurate and fast method especially suited for computerized design procedures.
Another demonstration that solution given by Eqn. 24 is only valid if the "+" sign, before its second term, is used, starts from the consideration that Eqn. A1 must hold:
XM - X 1 > 0 (A1)
The substitution of Eqn. 19 in Eqn. 18 gives:
Now the solution given by Eqn. 24 together with Eqn. 15 and Eqn. 16 are substituted in Eqn. A2 to give:
XM must satisfy Eqn. A1 as a precondition for the design; the substitution of Eqn. A3 in Eqn. A1 gives Eqn. A4:
After some rearrangement Eqn. A4 becomes in unequality Eqn. A5:
Let us call Q the second term, inside the first parenthesis, in the numerator of Eqn. A5.
It can be seen, because of Eqn. 26, that Q>0.; then Eqn. A6 follows:
Finally, from this expression it can be concluded that only if the "+" sign is taken in Eqn. A6 this holds.

Italy's crisis-hit Monte dei Paschi: half a millennium in banking
Published January 25, 2013
| Reuters
SIENA, Italy, Jan 25 (Reuters) - When the Monte dei Paschi di Siena bank was founded in 1472, Michelangelo was not born, Columbus had still to discover America and Henry VIII of England had yet to split from the church of Rome.
More than half a millennium later, the world's oldest bank is facing nearly $1 billion of trading losses in a scandal that has forced Italian authorities to issue reassurances about the stability of the Siena institution.
The bank's financial woes have raised the possibility that it could be nationalised, which would be one of the biggest upheavals since the marauding armies of the Duchy of Florence put an end to the Republic of Siena in 1555.
The politically charged affair follows hard on an investigation into Monte dei Paschi on suspicion that it manipulated markets and misled regulators when it bought its smaller rival Antonveneta from Spain's Santander in 2007.
The Siena bank, known as "Daddy Monte" because of its enormous influence and patronage, and its associated MPS foundation are as embedded in the psyche of the Sienese as the annual Palio horse race in which jockeys representing the city's historic quarters battle for supremacy on the sand-strewn main square of the Renaissance city.
The foundation is a politically powerful body meant to reinvest dividends in social and cultural projects. Its impressive art collection, housed in the city's Palazzo Salimbeni, spans six centuries.
Foundations like Monte dei Paschi's have stakes in all of Italy's leading banks but the MPS foundation is an anachronism even by Italian standards, clinging to power until it was forced to cede majority control last year in order to repay 1 billion euros of debts.
In good times, the bank's steady stream of dividends allowed the foundation to bankroll a myriad of projects in the city of Siena and the surrounding region -- strongholds of Italy's main centre left party, the PD.
With a month to go before a parliamentary election, it is those links to the PD that are coming increasingly under scrutiny.
The town hall and the province of Siena, both run by the PD, name 13 out of the 16 board members at the foundation, which in turns picks the majority of Monte Paschi's board representatives.
Between 1996 and 2010, the MPS foundation spent nearly 2 billion euros, more than half in the province of Siena alone, funding everything from a biotech facility to the building of roads to the training of horses for the Palio horse race.
In the meantime, the bank grew into Siena's largest private employer with 31,000 staff and six million customers.
An old adage says the city's 60,000 residents are divided into three categories: those who work for the Monte dei Paschi bank and foundation, those who are studying to work for it and those who are receiving pensions from MPS.
Critics have said that because their managers are handpicked by local authorities, the foundations only serve the interests of the politicians controlling them, a charge they deny.
"The foundations are an Italian scandal, they are the most powerful weapon in the hands of politicians to control the economy," Michele Boldrin, an Italian economist at Washington University in St Louis, once said.
"In the case of Monte dei Paschi, the city of Siena squandered its vast wealth just to keep a grip on the bank, so that politicians could keep their power," he said.
Indeed, keeping a tight grip on political power and patronage is something that critics say has guided Siena's rulers, from the princes of Machiavelli's times to the administrators of today.
But things began to go wrong in 2007, when Monte dei Paschi bought Antonveneta bank to expand its foothold in Italy's wealthy northeast, paying a whopping 9 billion euros in cash for it just months before the beginning of the financial crisis.
The acquisition catapulted the bank into Italy's big league -- making it the country's number three lender -- but it strained its finances to the limit. The bank is currently seeking a 3.9 billion euros ($5.2 billion) bailout from the Italian government.

Thomas Scheemakers
Thomas Scheemakers (1740 – 15 July 1808) was a sculptor operating in Britain in the late 18th century and a member of the important sculpting family of Scheemakers. Several of his works are held by the Victoria and Albert Museum.[1]
He was the only son of Peter Scheemakers (and grandson of Pieter Scheemaeckers), an eminent sculptor, and Barbara La Fosse. He appears to have been born slightly before their wedding.
From 1763 until 1780 he largely exhibited under his father's name. Whilst talented, he was certainly eclipsed by his father, but it is reasonable to expect that they worked together on several of his father's larger pieces up until his death (1781). He was a competent sculptor but lacked his father's flair for design, often leaving the design to be done by others. After his father returned to Belgium (c.1779) he continued his workshop, on Vine Street, London.
He inherited his father's huge fortune in 1782 but appears to have largely squandered this. He did very little sculpture after his father's death and ceased altogether in 1792. It appears that he went bankrupt in 1805, as there is a record of all of his effects being sold.[2]
He died in London in 1808 and was buried in the churchyard of St Pancras Old Church. The grave is lost (and was possibly unmarked even from the beginning) and he is not listed on the Burdett-Coutts Memorial to the famous graves lost, which stands in the churchyard.
His wife, Barbara (b.1747) died in 1810 and was probably buried with him.

An outbreak of "sea lice" has been reported on Florida's beaches. The lice leave the skin itchy, bumpy, and red after a quick dip in the ocean. Here's what we know so far about this outbreak:
On Monday, lifeguards in Pensacola, Florida reported some mild cases of "sea lice" and hoisted purple flags to warn beachgoers, according to WEAR TV. In serious cases, people can experience flu-like symptoms such as fever, headache, chills, and nausea in addition to the red and itchy rash.
"Sea lice," despite the name, is not actually lice. It's a rash caused by miniature larvae of marine life — like jellyfish or sea anemones. The term refers to the condition caused by the larvae stings, more accurately called "Sea Bather's Eruption," according to ABC Action News. Although scientists discourage the use of the term "sea lice" because it can cause confusion, the term became popular in the 1950s among locals who experienced the itchy rashes after swimming, according to the Florida Department of Health. Scientists also say added confusion can come in because there is actually a parasite that only affects fish which also happens to be called "sea lice."
These recent cases of Sea Bather's Eruption have been reported along 250 miles of Florida's southern Atlantic coastline for more than a century, according to the Florida Department of Health. Officials say cases peak from March through August and that shifting currents are to blame for the rash. Most outbreaks can be traced back to the larvae of the thimble jellyfish. They're visible to the naked eye, but they virtually disappear when in the water making avoiding them is impossible.
Pressure and friction on the jellyfish larvae cause the stinging cells, known as nematocysts, to fire and trigger a reaction on the skin. The Florida Department of Health says that in order to limit the chance of a reaction, "Swimmers should avoid wearing t-shirts while in the ocean… There is some evidence that use of a topical sunscreen or suntan lotion may actually protect skin from penetration by the nematocysts."
The rash is not life-threatening nor will it be likely to cause serious side effects, but care should be taken to mitigate the itching and pain. If stung by sea lice or other jellyfish, the National Institute of Health recommends applying vinegar to the skin to prevent further discharge of unfired nematocysts. People stung can treat the rash with antihistamines and over-the-counter hydrocortisone creams.

Around the spring and autumn equinoxes, the sun crosses the equator and traces an arc that is directly behind the geo-arc of satellites. A solar or sun transit outage is an electromagnetic phenomenon where a station downlink is temporarily unable to receive a satellite signal due to interference from the sun as it passes behind the satellite.
Solar outages occur on a predictable schedule, may last several minutes each day, and last longer the smaller the antenna is. Outages will occur at roughly the same time each day and may repeat on a daily basis for a week or more during the season.
This section provides calculated data on Solar Outages for the AMOS satellites platform. The solar outage prediction charts give specific dates for geographical locations, broken down by city and country.

By a mistake of Euler, the Diophantine equation y^2 - Ax^2 = 1 has been erroneously known as "Pell's equation"; but, in fact, the English mathematician John Pell (_PHONE_) did no more than copy it down in his papers, from Fermat's letters of 1657 and 1658.
For an extensive historical account on "Pell's equation", see Sir Thomas L. Heath, Diophantus of Alexandria : A Study in the History of Greek Algebra (Dover Pub., New York, _PHONE_, 552 pages), Supplement, Section II: "Equation y^2 - Ax^2 = 1, pp. 277-292. Particularly in page 285, after a presentation of the history of the equation up to Fermat's time (including citations to Pythagoreans, Archimedes, Diaphanous, and the Indian solution), one can read that:
"... Fermat rediscovered the problem and was the first to assert that the equation x^2 - Ay^2 = 1, where A is any integer not a square, always has an unlimited number of solutions in integers. His statement was made in a letter to Frénicle of February, 1657 (cf. Oeuvres de Fermat, II, pp.333-4). Fermat asks Frénicle for a general rule for finding, when any number not a square is given, squares which, when they are respectively multiplied by the given number and unity is added to the product, give squares. If, says Fermat, Frénicle cannot give a general rule, will he give the smallest value of y which will satisfy the equations 61y^2 + 1 = x^2 and 109y^2 + 1 = x^2? (Footnote 3: Fermat evidently chose these cases for their difficulty; the smallest values satisfying the first equation are y=226153980, x=_PHONE_, and the smallest values satisfying the second are y=15140424455100, x=158070671986249)." And, after a extensive quotation of Fermat's letter, in page 286, one can read that: "The challenge was taken up in England by William, Viscount Brouncker, first President of the Royal Society, and Wallis (Footnote 1: An excellent summary of the whole story is given in Wertheim's paper "Pierre Fermat's Streit mit John Wallis" in Abhandlungen zur Gesch. der Math., IX. Heft (Cantor-Festschrit), 1899, pp.557-576). See also H. Konen, Geschichte der Gleichung t^2-Du^2=1, Leipzig (S. Hirzel), 1901). At first, owing apparently to some misunderstanding, they thought that only rational, and not necessarily integral solutions were wanted, and found of course no difficulty in solving this easy problem. Fermat was, naturally, not satisfied with this solution, and Brouncker, attacking the problem again, finally succeeded in solving it. The method is set out in letters of Wallis (Footnote 2: Oeuvres de Fermat, III, pp.457-480, 490-503) of 17th December, 1657, and 30th January, 1658, and in chapter XCVIII of Wallis' Algebra; Euler also explains it fully in his Algebra (Footnote 3: Part II, chap. VII), wrongly attributing it to Pell (Footnote 4: This was the origin of the erroneous description of our equation as the "Pellian" equation. Hankel (in Zur Geschichte der Math. im Alterthum und Mittlelalter, p.203) supposed that the equation was so called because the solution was reproduced by Pell in an English translation (1668) by Thomas Brancker of Rahn's Algebra; but this is a misapprehension, as the so-called "Pellian" equation is not so much as mentioned in Pell's additions (Wertheim in Bibliotheca Mathematica, III, 1902, pp.124-6); Konen, pp.33-4 note). The attribution of the solution to Pell as a pure mistake of Euler's, probably due to a cursory reading by him of the second volume of Wallis' Opera where the solution of the equation ax^2 + 1 = y^2 is given as well as information as to Pell's work in indeterminate analysis. But Pell is not mentioned in connexion with the equation at all (Eneström in Bibliotheca Mathematica, III, 1902, p.206)."
For more information about "Pell's equation", see Harold M. Edwards, The Fermat's Last Theorem: A Genetic Introduction to Algebraic Number Theory (Springer-Verlag, New York, 1977, 410 pages), pp. 25-33. Particularly in page 33 one can read that
"This problem of Fermat is now known as "Pell's equation" as a result of a mistake on the part of Euler. In some way, perhaps from a confused recollection of Wallis's Algebra, Euler gained the mistaken impression that Wallis attributed the method of solving the problem not to Brouncker but to Pell, a contemporary of Wallis who is frequently mentioned in Wallis's works but who appears to have had nothing to do with the solution of Fermat's problem. Euler mentions this mistaken impression as early as 1730, when he was only 23 years old, and it is included in his definitive Introduction to Algebra written around 1770. Euler was the most widely read mathematical writer of his time, and the method from that time on has been associated with the name of Pell and the problem that it solved --- that of finding all integer solutions of y^2 - Ax^2 = 1 when A is a given number not a square --- has been known ever since as "Pell's equation", despite the fact that it was Fermat who first indicated the importance of the problem and despite the fact that Pell had nothing whatever to do with it."
See also André Weil, Number Theory : An approach through history - From Hammurapi to Legendre (Birkhäuser, Boston, 1984, xv+375 pages), in many different pages. In particular, at page 174, one can read that:
"Pell's name occurs frequently in Wallis's Algebra, but never in connection with the equation x^2 - Ny^2 = 1 to which his name, because of Euler's mistaken attribution, has remained attached; since its traditional designation as "Pell's equation" is unambiguous and convenient, we will go on using it, even though it is historically wrong."

Turning dirty water into gold
A small French start-up company is selling a technology with a hint of alchemy: turning water into gold.
It does so by extracting from industrial waste water the last traces of any rare - and increasingly valuable - metal.
"We leave only a microgramme per litre," said Steve van Zutphen, a Dutchman who founded Magpie Polymers last year with Frenchman Etienne Almoric.
"It's the equivalent of a sugar lump in an Olympic swimming pool," Almoric said.
Magpie Polymers operates from slightly shabby premises at a factory at Saint-Pierre-les-Nemours, 80km southeast of Paris. But it is at the leading edge of technology with a procedure developed at the prestigious Ecole Polytechnique in 2007.
The process is based on the use of tiny pellets of plastic resin through which waste water is pumped.
Gold, platinum, palladium and rhodium little by little stick to the pellets and are thus separated from the waste water. A single litre of this patented resin can treat 5m3 to 10m3 of waste water and recover 50g to 100g of precious metal, "equivalent to $3900 to $6500," Almoric said.
Cellphones, catalytic converters and countless other everyday products contain these precious metals. But once they are scrapped the problem lies in retrieving the precious metals.
"What is complicated is that the amounts are infinitesimal, and so hard to recover," said Van Zutphen.
Once they have been separated and crushed, some industrial waste products have to be dissolved with acid in water. Then the metals have to be recovered irrespective of whether they are valuable. Magpie will not name its chief clients but is active in "France, England, Belgium and Switzerland".

Does the Laplace equation on a rectangle with Dirichlet boundary conditions at two opposing sides and Neumann boundary conditions at the other two, always have a solution? If it does, is it unique? Is the same true for the discrete Laplace equation (with the standard five-point laplacian)?
share|improve this question
3 Answers 3
The solution to the Dirichlet problem is unique by the maximum principle. For the same reason, the solution to the Neumann problem is unique up to a constant.
At worst your problem would fail uniqueness by a constant, but those Dirichlet conditions you've got will prevent this.
This carries over to the discrete case. But note that the discrete case is an easier problem since you can just write out the matrix you need to invert and check if it's invertible.
share|improve this answer
I am not familiar with the discrete case. As for continuous case, I think you can use the method of images to solve this problem. It should always have a solution and it should be unique, due to the fact that the underlying Green's function is unique. In particular, to construct the Green's function, after reflecting by a Neumann or Dirichlet boundary, you put a same (resp. opposite) source (Delta function). By this way, we have an infinitely many sources, then your Green's function is the sum of the effects by all the sources. Hope it can help. :-)

I believe you can just use separation of variables.

The Benefits of TurfgrassHow we all benefit
At a time when global warming, air pollution, and carbon emissions are making world-wide news, it is important to take a closer look at turfgrass and the many benefits it has to offer. Most people take grass for granted, never thinking about the environmental, community, human health, and economic benefits it offers.
Dr. James Beard, Professor Emeritus of Texas A & M University and a leading authority of turfgrass, has often stated. "The environmental benefits of turfgrass are the most sensible and economically feasible approach to countering the greenhouse effect in urban areas."
Just how important is turfgrass as it relates to the world around us? The benefits we derive from turfgrass are considerable. Turfgrasses act as carbon sinks that remove carbon dioxide from the atmosphere while providing clean oxygen in return. A recent study has suggested that lawns actual store four times the carbon emissions of the lawn mowers used to maintain them.
Lawns also decrease the urban heat island effect and reduce the need for air conditioning in the summer – which reduces the use of fossil fuels and water. Turfgrass lawns provide erosion control, keeping surface waters clean by decreasing run-off and helping to purify water before it reaches aquifers. It has been scientifically proven that install of well-maintained turfgrass lawns around freshwater sources are better at keeping contaminants out of the water, compared to re-established native prairie mixes.


Lowell Gun Charges Lawyer
Discover lawyers for gun charges serving Lowell, Belmont, and the Greater Boston area
Massachusetts has one of the toughest sets of gun laws in the United States with very harsh mandatory sentences imposed for illegal possession or carrying. Gun laws regulate the sale, possession, and use of firearms and ammunition. Firearm owners must be licensed through their local police department or the Massachusetts State Police if no local licensing authority is available. An applicant must have passed a state approved firearm safety course before applying for a license. A license is required for buying firearms and ammunition and the seller must verify the validity of the license prior to sale.
Typical gun charges involve the possession of a firearm without a valid Firearm Identification (FID) or carrying a firearm without a valid License to Carry (LTC). Alternatively, the accused may be accused of possessing a firearm that is illegal in Massachusetts or may not have the appropriate licensing for the particular weapon. If you have been convicted on gun charges or have any questions you want to ask lawyers for gun charges, please contact me, your Boston and Lowell-area gun charges lawyer for a free consultation.
In order to convict someone of the illegal carrying of a firearm, the Commonwealth must prove beyond a reasonable doubt that:
 1. The defendant possessed a firearm or had a firearm under his or her control in a car;
 2. The weapon met the legal definition of a "firearm;"
 3. The defendant knew he or she possessed the firearm; and
 4. The defendant was outside of his or her residence or place of business.
A firearm is defined as a pistol, revolver or other weapon, loaded or unloaded, from which a shot or bullet can be discharged and the length of whose barrel is less than sixteen inches.
Possession of a firearm is charged when the defendant illegally possessed a gun in his or her home or business. Possession of ammunition is a separate charge. Possession of specific types of firearms, such as a sawed-off shotgun, a gun with a defaced serial number, or a high-capacity firearm, carry enhanced penalties including minimum mandatory state prison sentences. Experienced lawyers for gun charges can help you understand the difference.
"Keren represented me on a gun case where I was acting in self-defense. She not only got the case against me dismissed but helped me get my LTC restored. Every time we would talk it was like a weight got lifted off my shoulders."
License or Expired License
A defense to possessing or carrying an unlicensed firearm is that the accused has a license, and in some cases, an expired license. The police will typically do a Massachusetts license check when they come across someone in possession of a firearm and do not do any further inquiry before charging. In one of my cases, my client was pulled over when traveling from Maine and the police found a shotgun in his trunk. A shotgun does not require an FID in Maine and although Massachusetts guns laws apply to people with guns in Massachusetts, there is a travel exception for someone who is passing through (not stopping for anything beyond food and gas) the state for lawful purposes.
In another case, a client who had been arrested on an unrelated matter faced additional gun charges because when the police executed a search warrant when investigating the first case, and found rifles and shotguns. My client had an expired FID card. The police charged him and the prosecutor indicted him, all unaware that he fell under an exemption to the heavy criminal penalties imposed on people found in possession of firearms without a valid license. A person in possession of rifles or shotguns with an expired FID card, who has never been rejected in an attempt to renew it, only faces a civil fine for those guns. This is another instance where experienced lawyers for gun charges can make a significant difference.
Not a Firearm
Guns need to be operational to qualify as a firearm which means that they need to work. A client was charged with possession of a sawed-off shotgun even though the stock was not only removed – it was missing. In cases where I have reason to believe that the gun is not operational, I hire a certified firearms expert to examine the weapon and watch the police's test-firing of the alleged firearm to make sure that they don't make any repairs to render it operational.
No Possession
In cases where the gun is found in a house, car, or anywhere other than on the accused's body, a defense that the gun was not possessed by the person charged becomes viable. In cases like this, the police will typically find a gun hidden in a nearby location to where the accused has been stopped and the defense is that the gun was not his. In an unusual case, my client's girlfriend went to the police and told the officers that there was a gun stashed in the closet of the house that belonged to him. The police took the gun and charged my client with illegal possession of the gun. Because the police did not fingerprint the gun or otherwise tie the gun to him, it was possible to argue that the gun belonged to someone other than him.
Guns are often seized under chaotic circumstances during encounters with the police and the officers often ignore constitutional protections against illegal searches. As such, guns are routinely subject to suppression from evidence because police illegally searched a person, home or car for a possible firearm.
A large capacity gun found in my client's car was suppressed in the Superior Court because the police improperly pulled my client over for no valid reason. The police alleged that they stopped the car because of excessively tinted windows. Before approaching the car, the officer ran the plate which was registered to a woman and was shown to a warrant. Upon approaching the car he saw my male client sitting in the car and also should have been able to see that the tinted windows had the markings of having been installed by the manufacturer which exempts the car from the tinting law. The judge held that as soon as the officers approached the car and saw a male driver and the window markings, they should have let him go without any further demand for his license. The case was dismissed since the evidence of an illegal firearm was suppressed.
A judge in the Superior Court suppressed guns and several pounds of marijuana after police kicked down the door of an apartment following a report that a man had been beaten up and threatened with a gun. The detective who authored the police report claimed that officers noticed the guns and drugs in plain view as they quickly went through the apartment to make sure that there were no people who posed a threat to them. I demanded the "turret tape" which is a recording of all police communications over the radio and called all 9 officers who responded to the scene. Through their testimony and the recording I was able to establish that the people in the apartment had already been taken outside and arrested long before the police found the guns during an illegal warrantless search. The case was dismissed since the evidence had been suppressed.
If you have been charged with a gun offense, you need a lawyer who knows the gun laws and has expertise in suppression matters. I have repeatedly lectured on illegal searches during police encounters and have a proven track record of winning suppression motions. I can bring that knowledge and experience to your case.

The impact of electrical load shifting strategies on storage capacity and service provision of domestic hot water systems in residential buildings
conference contributionposted on 06.06.2017, 12:27 by Dashamir Marini, Richard Buswell, Christina Hopfe
Domestic hot water can accounts for up to 25% of the total domestic energy consumption in the UK and is demand driven. In the UK there has been a trend to replace traditional tank systems with instantaneous supply of hot water through gas fired combination boilers, leaving the space occupied by the tank to be repurposed by the household. This space is likely to become more critical as the need for storage increases in order to participate in peak load shifting when spaceheating and hot water is supplied by electricity rather than gas. The size of tank and hence the delivery of water at an appropriate temperature delivered when demand dictate is likely to become a point of tension in future systems. This paper introduces a notion of hot water 'service' that can be evaluated and used to compare the performance of different systems, along side more traditional metrics such as cost, power and tank size. The analysis compares several load shifting strategies through a TRNSYS model driven by high resolution hot water data (1sec) measured in a UK home. It is demonstrated that optimal tank size and the service the system can provide are very sensitive to the load shifting strategy applied.

In his post yesterday on Common Eiders, Corey quoted Pete Dunne's Essential Field Guide Companion on eider distribution: "Several decades ago, King Eider was the expected wintering eider south of New England. Sightings of Common Eider were considerably fewer. This has changed, and Common Eider now lives up to its name, outnumbering King Eider along the mid-Atlantic coast." Curious about this, I decided to check some historical sources to see when things changed.
John Bull's Birds of the New York Area (1964) states that King Eider was historically seen more frequently than Common Eider off Montauk in Long Island. It attributes changes in winter distribution to population growth at the Common Eider's breeding grounds. For example, the breeding flock at Muscongus Bay in Maine grew from 800 in 1949 to 6,000 in 1959. Bull also mentions an impressive irruption of King Eiders in the winter of 1887, in which flocks of 20 and 30 were recorded.
For historical records in coastal New Jersey, one place to turn is Witmer Stone's Bird Studies at Old Cape May. This book was first published in 1937 based on observations from the preceding decades. What makes the book valuable is that Stone reports his own observations as well as those of other ornithologists and sometimes cites 18th and 19th century observers as well. Though dated, it provides an interesting window into past bird distribution in the state. Regarding eiders, Stone first notes that many observers (including hunters) were unfamiliar with either King or Common Eiders. (Stone refers to Common Eiders as American Eiders.) He then lists observations for Common Eiders in the Cape May area:
The only records that we have were made by the Audubon Association wardens stationed at the Point. A female or immature male was seen by William Rusling on the ocean off Cape May Point near the jetties in front of the Villa Maria. It remained there from October 10 to 14, 1935, and he watched it several times a day for four days having it in good view, once within twenty-five feet. When caught by the tide and carried out from shore it immediately swam back to the jetties. He identified it as an American Eider.Turning to King Eider, Stone notes that most of the specimens are young birds and that there had been no recent sightings in Cape May County, but that specimens had been shot in 1928 (in Great Bay) and 1900 (on the lower Delaware). He continues:
Three were seen off the end of the jetty at the entrance to the Harbor, on November 3, 1936, by James Tanner.
In the Barnegat Bay region several of these ducks have been seen. Charles Urner sends me the following list: One on November 3, 1930 (Harry Ridgway); a drake, January 11, 1931; one on December 27, 1931 (Lester Walsh and Charles Nichols); two on December 17, 1932 (Oscar Eyre); one drake, on December 26, 1932 (Urner and others); one young drake, February 18, 1934 (Urner).
Charles Urner sends me the following list of individuals observed in the Barnegat Bay region by him or his associates: One December 15, 1924, (Watson); one March 3, 1929 (Jacques); two November 9, 1930; one January 14, 1934; two February 4, 1934; four February 18, 1934. The 1934 birds were seen immediately following the extremely cold weather of that winter which was undoubtedly the cause of their southward wandering.The impression I get from Stone is that neither species was common but that both made regular appearances along New Jersey's southern coast, either singly or in groups. I do not know of a similar resource for more recent decades, though one could probably piece it together by going through back issues of New Jersey Birds and its predecessors. As an alternative, I turned to archived Christmas Bird Counts. Using historical CBC data presents problems since participation and coverage have changed over time and count circles have gone in and out of existence. However, using birds per party hour controls somewhat for effort and New Jersey has some long-running counts along the coast. Here is graph for New Jersey since the winter of 1940-41, roughly Stone's time to ours.

A typical example of almost pure dependent marking is Japanese, where each part of a sentence is supposed to be marked for its function (topic, subject, object, complement), while the verb is completely devoid of morphological marks showing person, number, gender, or any other property of the arguments.
Less pure examples are Czech, Latin, Spanish, German, and English. In English, the word order determines the role of the nouns in the sentence, so neither the head nor dependent are usually marked in the case of the verb phrase.

Theories of subjectivity (Freud, Lacan and Irigaray) are used to examine the representation of the central protagonist's existential crisis in Gunter Grass's novel 'The Tin Drum' (1959). I trace the theme of anxiety surrounding origins and the motif of returning to the umbilical cord. I concentrate on the complex way that imagery works in Grass's text. In 'The Tin Drum' images do not often correspond to just one idea but resonate with multiple meanings, and often a motif can mean two opposing things at the same time. This is true of the motif of returning to the umbilical cord, which at first appears to allude to escapism, and is then associated with an intense mode of remembering. "Getting back to the umbilical cord" thus means both escape from history (not facing reality) and getting back to history (remembering the details of the past that we have repressed or forgotten). The complex character of Oskar alludes to the dangers of both engaging and not engaging with the world and society. In both narrating birth and avoiding thinking it fully, the text suggests Oskar's reluctance to think origins, change and relationality, which is symptomatic of his desire to 'escape' from history. But the text simultaneously emphasizes that this escape is impossible. The motif of escaping/remembering history resonates on other levels of time--such as West Germany in 1959--and can highlight complexities of specific historical moments: the general reluctance to engage with German history during the 1950s, together with the growing realization of the impossibility of avoiding this activity and articulations from some quarters of the critical need to think through the German past.

In Vim, with., I can repeat the last normal mode command; for example:
deletes a line twice.
But, if I type
the cursor does't move 10 lines down. How do I repeat the last normal mode command, especially a move?
 - why don't you accept one of the answers below? you forgot about it, or there's a reason? – Stephane Rolland May 3 at 13:43
it's doable even in vanilla vim, but applicability depends on your use case, ie. how often you'll need to repeat it, since it requires few more keystrokes to make it repeatable.
Option 1: turn it into a command mode operation
using moving down 5 lines as example, you can do:
 1. enter :norm 5j, it'll move the cursor down 5 lines
 2. use @: to repeat the movement
:norm stands for normal, any following string is regarded as your keystrokes under normal mode
Option 2: Use macro
 1. qa (store macro into register a, you can pick your own register like qb, qc)
 2. 5j
 3. q (finish recording macro)
 4. _USER_ to repeat your recorded operation (replace a with the register name you picked, eg. _USER_, _USER_)
macro requires more spiritual power to set up but it's more repeatable in the sense that you can store multiple operations in different registers without being overriden by latest operations.

vim doesn't do this unfortunately. The best you can do is install the repmo.vim plugin, which repeats movement commands that have a count.

Actually. repeats the last change, not the last normal mode command. As Paul said, you will need a plugin to allow you to repeat motions.
See ":help.".

You can repeat changes with.. Movements can be repeated with the ; command. This command seems to be new and does a similar thing to the repmo.vim script mentioned in other answers.
For example, to move to the second next c, press 2fc. Then to do it again, just type ;.

 ; isn't new. It's a standard vi command. Vi remembers the type and target character (but not numerical argument) of the last f/F/t/ T motion and ; repeats it. It doesn't repeat other motions, however. – pyrocrasty Jun 4 '15 at 2:47
 - This accomplished what I was looking to do! thank you. and thank you _USER_ for the clarification! – Paul Nov 30 '18 at 18:55
You can select the lines you want to change and execute last normal dot command

Anti-Slavery Convention of American Women
The first Anti-Slavery Convention of American Women was held on May 9, 1837. Approximately 200 women gathered in New York City to discuss their role in the American abolition movement. Mary S. Parker was the President of the gathering. Other prominent women went on to be vocal members of the Women's Suffrage Movement, including Lucretia Mott, the Grimké sisters, and Lydia Maria Child. The attendees included women of color, the wives and daughters of slaveholders, and women of low economic status. The convention was a monumental step, both for the women's rights movement, and the abolition movement as a whole. Despite the event's significance, it receives very little historical attention.


How to tune a car sound system: adding a 4-channel amp
Buck Pomerantz

Rockford Fosgate Power T400X4ad 4-channel amplifier
Adding a 4-channel amp to your car stereo system — two channels to run the front speakers and two channels to run the rear speakers — not only raises the sound level, but also greatly increases the sound quality of your music. This is how I'd tune it up:
 1. Before turning on your system, make sure your amplifier's gains are set to their minimums, their highand low-pass filters are off (set to "all pass" or flat), and that any bass and treble boosts are also off.
 2. Turn on all the units of your system. Set your receiver's tone or EQ controls, its balance, and its fade to their middle, off, or flat positions. Note where the settings were as you might want to restore them later. If you have a subwoofer in your system, turn its amp gain all the way down.
 3. Play your test music. That's a recording you are very familiar with and know what it's supposed to sound like. It has plenty of sonic variety: lots of very high notes like flutes, brass, and cymbals, lots of mid-range content like piano, guitar, and vocals, and lots of very low notes like bass and drums. And you will listen to it over and over again. (For steps 4 through 10, while you're setting the amplifier's gains, it is best to play the loudest passages of your song selection.)
 4. Set the receiver's fade control all the way to the front speakers.
 5. With your amplifier's gain controls still all the way down, turn the receiver's volume up to ¾ full, or until the music sounds distorted. (If you don't hear any music at all, try turning the amp's front gain control up slightly until you do.) If you hear distortion, turn down the receiver's volume until the distortion goes away and the music sounds clean.
 6. Now turn up the front gain control of your amp until the music distorts, then turn it down so it plays clean again.
 7. Turn the receiver volume down.
 8. Set the receiver's fade control all the way to the rear speakers.
 9. Again, turn the receiver's volume up to ¾ full and turn up the rear gain control of your amp until the music distorts, then turn it down so it plays clean again.
 10. Turn the receiver volume down.
 11. If you have no subwoofer in your system, restore your receiver's original tone, balance, and fade settings now. Or, you can refer to "How to Tune a Car Sound System: Part 1" for help in tuning your stereo to sound its best. Another tip is to engage the high-pass filter on the front channels of your 4-channel amp, and tune it to eliminate some of the low notes coming from the front speakers in order to bring extra clarity to your soundstage. (That's the ability of your stereo to sound like a band is playing in front of you, live in your car.)
 12. If you do have a subwoofer in your system, adjust the receiver's fade control to the front speakers only and turn up the volume until the music is loud, but not uncomfortable. Engage the high-pass filter of the amplifier's front channels and adjust it so the bass notes disappear. Fade the receiver to the rear speakers only and engage and adjust the rear channels' high-pass filter until the bass disappears there too. Return your receiver's fade control to its original position.
 13. Slowly turn up the gain of your subwoofer amplifier until the bass notes sound balanced and smoothly blended with the rest of the music. Your sub amp's low-pass filter should already be tuned to reproduce only the low notes. You can refer to Tuning Your Subs, for help in fine-tuning your subwoofer system.
 14. If your highs and lows seem balanced but the bass sounds like it's coming from the rear, adjust the sub amp's low-pass filter lower to "de-localize" it. Pay close attention to the "crossover area", the parts of the music played by both the full-range speakers and your subwoofer. Smooth any roughness by fine-tuning the filters. For instance, if the vocals sound tinny, you can adjust the high-pass filters on your 4-channel amp to include more low notes. If the vocals sound boomy, tune the high-pass filters higher.
Take your time and tune it all for your own ears and you will never go wrong.

A hatch pattern consists of a repeating pattern of lines, dashes, and dots. You can select a hatch pattern from a set of predefined patterns, or you can define a pattern of your own. The hatch pattern you used most recently is the default pattern the next time you choose Hatch.
The program supplies predefined standard hatch patterns, which are stored in the icad.pat and icadiso.pat hatch pattern library files. You can use other external hatch pattern libraries, such as an office standard library, customized patterns, and libraries available from vendors or standards organizations.
NOTE The icad.pat hatch pattern library files are ANSI (American National Standards Institute)-compliant patterns; the icadiso.pat hatch pattern library files are ISO (International Standards Organization)-compliant.
You can add hatching to an area enclosed by entities selected to form the hatch boundary. The entire hatch is treated as a single entity. After you draw a hatch, it is independent of the entity itself.
You can also use an existing entity to define the area you want to hatch. You can associate the hatch with its boundary entities by selecting Associative from the Hatch Attributes area of the Hatch dialog box
1. From the Boundary Hatch dialog box, click the Boundary tab.
2. Choose one of the following Island Detection Options:
- Nested Islands The outer entity and all its islands are considered for hatching.
- Outer Only Only the outer entity and its outer island are considered for hatching.
- Ignore Islands Only the outer entity is considered for hatching.
Nested Islands Outer Only Ignore Islands
3. To keep the boundary, select the Retain Boundaries check box.

 Something that was much insisted on when I was at school, because i guess some kids found it hard to get their heads round. Like 1M HCl or NaOH are 1N but 1M H2SO4 or Na2CO3 are 2N. You get the idea? - it's the same as the distinction between molar masses and equivalent masses (or weights as we used to call them).
 I think they have been phased out of teaching now, have they? If so it's no loss, they are unnecessary.

 Normality meant different things at different moments in time. There was a period when normality depended on the reaction - so 1M sulfuric acid was 2N in the reaction with NaOH, but 1N inteh reaction with CaCl. Then IUPAC decided to make it always reaction with H+ or e- - so 1M sulfuric acid would be always 2N. Then, IUPAC decided they created so much confusion it is better to deprecate normality at all.

Position of max value in list
Excel formula: Position of max value in list
Generic formula
To get the position of the maximum value in a range (i.e. a list, table, or row), you can use the MAX function together with the MATCH function.
In the example shown, the formula in I5 is:
Which returns the number 4, representing the position in this list of the the most expensive property.
In this case, that value is 849900.
With those arguments, MATCH locates finds the maximum value inside the range and returns the relative position of the value in that range.
In this case, the position corresponds to a relative row number, but in a horizontal range, the position would correspond to a relative column number.
Note: in case of duplicates (i.e. two or more max values that are the same) this formula will return the position of the first match, the default behavior of the MATCH function.

Why Choose Black And White Photography
We see and live in a world full of colors. That is how we have evolved and it is naturally, the world that we know. There are different schools of thought when it comes to black and white photography. Some individuals believe that this was a technical limitation of the past and people need to get over it.
While others still believe that it is still an inventive choice that needs to even be reconnoitered in great depths. As the camera technology evolves, with more emphasis being placed on improved colors, why would one choose to shoot or process their images in black and white?
In this article, we take a look at the top reason why you might consider shooting, processing or converting your images to black and white.
1. Black and white helps you see differently
In the old adage, the photographers took shots in black and white, because they had no choice. However, even with the Kodachrome that introduced the world to color, there is still pursuance of black and white photos. This is due to the fact that black and white was and still is being seen as photography in its purest form. Whenever color is removed from the equation of an image, the emphasis shifts to the compositional element of the photo.
These factors include shape, lines, texture, tones, and contrasts. With this in mind, it is obvious that not all pictures will translate to black and white, thus as a photographer, you will have to deduce something else to work with besides the color. Most of the time, black and white assist you develop a different perspective from what you are used to seeing. This helps nurture your photographic eye.
2. Eliminates distractions
Human beings are set to view the world in color and there is absolutely nothing wrong with that. At times, this contributes to other elements that might be lost. Some of the elements that are required in photography include texture, lighting, form, and shape.
When you take a shot in black and white, your challenge yourself to remove all the distractions of color. These include color cats and the difference in color temperature, and strong colorful elements that might reside on the background of the image.
Monochromic imagery always forces photographers to focus on shape, form, and texture while composing the image. With black and white photography, the distractions are removed and the colors are translated to gray that add to the image.
3. Offers Creative Choice
Since the world is obsessed with color, it is always safe to say the color depicts reality, hence the black and white photography is depicted as a rendition of reality.
When color is removed from an image, you not only isolate the different elements but also be compelled to find how they relate to each other. Therefore, it helps you to explore and create a different way of telling a story.
4. Adds mood and emotion
The variance tonal ranges or rich black and deep contrasts always appeal human psychologically. It helps create the connection that makes one stop and pay attention to whatever is being presented. Most photographers use black and white in storytelling, especially in street photography. In some genres, monochrome connects, strengthens and enhances mood and emotion.
