For inflatable dinghies, it is inevitable that water will enter the ship when entering the ocean. After all, the ship's side is not very high, but this problem is not to worry. Inflatable assault boats are known as never wrecking, and even if the ship is filled with water, it will not sink. The hull pontoon has a large storage capacity and a strong buoyancy capability. Generally, if the water in the ship is full of buoyancy, it can be fully withstood. Wet body is a must, this is what makes inflatable dinghy different!
 However, even if it is into the sea, the inflatable dinghies rarely have water inflow. Most of the time, the ocean is gentle, there is not much wind and waves, and there is no need to worry about seawater splashing into the ship. If there is a large wind and waves, the sea water constantly rushes into the ship, first keep calm, because even if the ship is filled with sea water, the buoyancy of the hull can still withstand, the only thing to do is to keep the hull stable. When the ship is filled with water, the gravity will oscillate with the water flow, and in severe cases it may cause the ship to turn over, so it is important to maintain the hull smooth. Note: If water is constantly coming in, there is a drain valve at the end of the assault boat. Open the drain valve so that the seawater can flow out by itself.
The solution after the inflatable rubber boat enters the water;There is no way to solve the problem of the water inflated rubber boat. The only way is to keep the hull balance and open the drain valve. However, there are still some solutions to other problems.
1. When the sea water enters the ship, the clothes will be wet. You can buy a waterproof skirt to ensure that the clothes are not wet and keep warm.
2, you can prepare a water scoop, the ship can be crowded out of the sea water for a long time, to avoid excessive weight loss.
3, due to wave fluctuations will cause the hull to appear high and low, so the sea water can not be drained with water scoop and drain valve, you can spare a sponge to drain the remaining water.
The threat of water ingress is not great, and the biggest safety hazard is to overturn the ship. It is also said above that if the ship is filled with sea water, it will cause the hull to lose weight and overturn. If there is a real overturn, we have to use the following self-rescue methods;
1. When the ship has serious weight loss, first grasp the safety rope first, and when the ship turns over, it will not be taken away by the wind and waves. (Note; be prepared before overturning, not to be crushed by an inflatable rubber boat)
2. Before the wind and waves are fixed, do not try to flip the hull back. You should grab the safety rope and keep the head out of the water.
3. After the wind and waves calmed down, I began to think of ways to flip the boat back and board the ship again. (Note; if it is a person, due to the hull being too heavy, you should give up after trying two times without fruit, to avoid losing too much physical strength)
4, when waiting for the ship again, people need to cooperate well for a long time, press the upper right and press the left upper right to avoid losing weight again.
5. After returning to the ship, if it is scraped off the shore by the wind and waves, please do not try to use the paddle to return to the shore. You should use the communication equipment to call for help and wait for the rescue.
1. Before you enter the sea, you must wear a life jacket and other rescue buoys.
2, must bring the communication equipment, and wrapped in a sealed bag in the underwear, in case you need it from time to time.

Watch a Pig Decompose Underwater
By Casey Chan on at
Pork is absolutely delicious any which way you cook it, and it seems like sea lice, which are like ocean maggots apparently, would agree too. The sea lice do most of the heavy eating, before shrimp come in to finish the job. It's disturbingly exciting.
Why did scientists throw a dead pig in the ocean? Well, they wanted to get a better idea of how bodies decompose underwater. The experiment, led by forensic scientist Gail Anderson from Simon Fraser University in Canada, shows a pig carcass inside a cage and tracks its entire progress. New Scientist says:
Shrimp come into finish the job but when the scientists retrieved the bones, they were "strangely" jet black for 48 hours. They've never seen that before and are looking at what caused the turn in colour. Watch the video, it ain't pretty. [New Scientist via BoingBoing]

Formulary managers
Do you want to give physicians access to your formulary?
Medication management is the key to an electronic prescription system. Formularies are not booklets that can be flicked through occasionally, but crucial links in the clinical process with many national, regional and local implications.
Various existing formularies are accessible in Prescriptor, including NHG-formularium, Formularium Nijmegen, Groninger Formularium, and ETAS. These formularies are maintained regionally or locally and can be accessed by the prescribers using Prescriptor and a special license key. The advantage is that regional agreements in the clinical practice automatically appear on the 'desktop', which promotes compliance. This allows better coordination of regional and local (transmural) therapy guidelines for the purpose of efficiency and drug safety.

Work Out With Your Dog - How Animal Agility Training Can Burn Calories For You
The University of Massachusetts studied human oxygen consumption during canine agility training. John Ales
Vigorous Exercise for Dog and Human
Researchers at the University of Massachusetts Department of Kinesiology have studied the impact on humans during canine agility training, and their findings were recently highlighted on Zoom Room Dog Agility Training Center's website.
The researchers looked at oxygen consumption (using a face mask and battery-operated, portable metabolic system that measures breath-by-breath gas exchange) as well as heart rate (detected and recorded using a Polar heart rate monitor). The data collected was translated into Metabolic Equivalents, or METs, a way of comparing how much energy a person expends at rest versus during a given activity.

- stump (n.)
- mid-14c., "remaining part of a severed arm or leg," from or cognate with Middle Low German stump (from adjective meaning "mutilated, blunt, dull"), Middle Dutch stomp "stump," from Proto-Germanic *stump- (cf. Old Norse stumpr, Old High German and German stumpf "stump," German Stummel "piece cut off"), perhaps related to the root of stub or stamp, but the connection in each case presents difficulties.
Earliest form of the word in English is a now-obsolete verb meaning "to stumble over a tree-stump or other obstacle," attested from mid-13c. Meaning "part of a tree trunk left in the ground after felling" is from mid-15c. Sense of "walk clumsily" is first recorded c.1600; that of "baffle" is first recorded 1807, perhaps in reference to plowing newly cleared land.
- stump (v.)
- "to go on a speaking tour during a political campaign," 1838, American English, from phrase stump speech (1820), from stump (n.), large tree stumps being a natural perch for rural orators (this custom is attested from 1775).

How Much to Separate?
The Torah does not specify an amount that must be separated for challah, bikkurim, or terumah. By contrast, it does specify that one-tenth of the crop is given to a Levi as ma'aser. The Sages determined that a professional baker separates one out of forty-eight parts, while a lay baker separates one out of twenty-four parts.
Why does the professional give less challah? The Ateres Zahav states that the Sages were more lenient with a baker because baking is his livelihood, and the Sages wanted him to enjoy more of the fruits of his labor. The Rambam writes that whereas a baker generally deals with large portions of dough, the amount that he separates, even at the smaller one-forty-eighth ratio, generally is large enough to make a suitable gift to the kohen. A housewife kneads smaller quantities, so that a larger percentage, one-twenty-fourth, is required to make her gift suitable.
The Lubavitcher Rebbe advances a more esoteric reason for the difference. He explains that G-d wants us to perceive His providence in all that we do. A professional baker is heavily reliant upon a good planting season and a good harvest. He carefully monitors these and thereby witnesses G-d's providence throughout the process of flour manufacture. A non-professional sees only the final product. He must give a greater percentage, so that he will have a greater awareness of G-d's manifestation.
Today, because the mitzvah of challah is Rabbinic in nature, there is no minimum amount that must be taken. In Israel, there is a widely observed custom to take a k'zayis, the size of an egg.
While both men and women have the obligation to separate challah, this is among the mitzvos that were specially entrusted to women. Where both husband and wife are involved in making dough, it is preferable for the wife to separate the challah.
How large must the dough mass be to require the taking of challah? One must take challah if the dough is at minimum the size of an omer, equivalent to a volume of forty-three and one-fifth eggs. (The omer is the standard of measurement for food in the Torah.) There is a disagreement concerning the precise measurement of an omer. There is a consensus that dough weighing five pounds meets the minimum size requirement. A consensus exists as well that dough weighing less than two and one half pounds is too small to require the taking of challah. Therefore, when one kneads five or more pounds of dough, she recites the blessing. If kneading less than two and a half pounds, she does not take challah at all. When kneading dough that weighs between two and a half pounds and five pounds, one does take challah, but should consult a competent Orthodox rabbi regarding the recitation of the blessing.
The blessing made for the taking of challah is "who sanctified us with His commandments and commanded us to separate challah." A common custom is to say "... to separate challah from the dough." This latter version is not recorded in the Shulchan Aruch, and the Taz, one of the principal commentators on the Shulchan Aruch, notes that he does not know the basis for it. Nonetheless, the custom in many circles is to add the words "from the dough."
Challah is taken only from five grains: wheat, oats, rye, spelt, and barley. Challah is not taken from rice, corn, or other grains with which dough may be made. Also, challah is taken once the flour and water have been mixed; it cannot be taken before the kneading has been done. And it should be taken before the dough is baked; nonetheless, if one neglected to separate challah before baking, she does so after baking. (In Passover matzoh baking, where we must complete the baking process quickly, we take challah only after baking.)
We separate challah from cake doughs as well as from bread doughs; however, if the majority of the liquid content is juice rather than water, we do not make the blessing. If none of the liquid is water, it is preferable to add a little water and separate challah. (For a detailed, practical exposition of the challah laws, see Spice and Spirit: The Complete Kosher Jewish Cookbook.)
The mitzvah of taking challah serves a number of purposes. It connects the mundane act of food preparation to G-d, by reminding us that He is the true owner of the land. It also establishes a bond between the common folk and the kohanim, the priests, who are ideally the recipients of the challah. The kohanim, by virtue of the fact that they were deeply involved in the service at the Temple, were unable to engage in farming on a regular basis. Challah, terumah, and the other gifts given them afforded the kohanim sustenance as they performed their work.
Today we do not give challah to the kohanim. While we do have kohanim in our midst, we are unable to verify their lineage beyond any doubt. A non-kohen is not permitted to eat challah. Therefore, we destroy the challah by burning it to the point that it is inedible. (Walk into a kosher pizza store, and you will often see a crisply burned ball of dough resting on top of the oven. This is the challah.)

Inner and Outer Corners
The next thing we need to take note of it the idea of an "inner corner" and an "outer corner" of a Ferrers diagram, and thus of a partition.
An inner corner of a Ferrers diagram is a cell that, if it's removed, the rest of the diagram is still the Ferrers diagram of a partition. It must be the rightmost cell in its row, and the bottommost cell in its column. Similarly, an outer corner is one that, if it's added to the diagram, the result is still the Ferrers diagram of a partition. This is a little more subtle: it must be just to the right of the end of a row, and just below the bottom of a column.
As an example, consider the partition, with Ferrers diagram
We highlight the inner corners by shrinking them, and mark the outer corners with circles:
That is, there are three ways we could remove a cell and still have the Ferrers diagram of a partition:
And there are four ways that we could add a cell and still have the Ferrers diagram of a partition:
If the first partition is, we write a generic partition that comes from removing a single inner corner by. Similarly, we write a generic partition that comes from adding a single outer corner by. In our case, if, then the three possible partitions are,, and, while the four possible partitions are,,, and.
Now, as a quick use of this concept, think about how to fill a Ferrers diagram to make a standard Young tableau. It should be clear that since is the largest entry in the tableau, it must be in the rightmost cell of its row and the bottommost cell of its column in order for the tableau to be standard. Thus must occur in an inner corner. This means that we can describe any standard tableau by picking which inner corner contains, removing that corner, and filling the rest with a standard tableau with entries. Thus, the number of standard -tableaux is the sum of all the standard -tableaux:

Although rhodochrosite is found in many different localities, only a few supply the compact material which is used as an ornamental stone. It is commonly found in the form of stalactites and stalagmites in the caves of Argentina. Its use as an ornamental stone began just before the commencement of World War II, when a quantity of this stone came from San Luis in Argentina. The deposit from which it came was said to have been found in a long-disused mine situated on a mountain fissure at a high altitude, which was reputedly worked by the Incas for silver and copper during the thirteenth century. The Incas, who called it Inca Rose, believed that rhodochrosite is the blood of their former kings and queens / that was turned to stone.

IMEC Mini‐Pal ‐‐ Minipal is the Palletizing System offered by Process Integration to all of those companies that need to enclose the end of line activities within a limited area.
The machine is formed of a Cartesian centerpiece system made up of three linear axis and a circular axis for product rotation. This structure has the advantage to have considerably smaller overall dimension than the traditional Cartesian portal palletizers. and allows for substantial performance improvements. Lifting can be done by either grippers or suction cups, depending on the product to be palletized.
Minipal can be employed with more pallets and different feeding lines simultaneously, so it can be used for multiple stacking applications.
The standard system is made up of a single feeding conveyor, while the empty pallet's positioning and removal of the filled one is made by an operator. It is possible to increase the machine productivity by providing a completely automatic pallet feeding and removal system that includes a pallet magazine for about 10 units thus reducing load and discharge times.Download PDF and Watch Video

Racial, ethnic and gender differentials in socio-economic status : the Israeli labor market case
MetadataShow full item record
In the present study, data from the Labor Force Surveys of Israel's Central Bureau of Statistics (CBS) for the years 1990 and 2000 are used to examine the occupational segregation in the Israeli labor market based on the 5 ethnic sub-samples including European-American Jews, Asian-African Jews, Russian Jews, Native-Born Jews and Non-Jews who mainly represent the Arab citizens of Israel. The analysis is done separately for men and women to avoid interaction since men and women demonstrate different labor market characteristics in general and in Israel. OLS regression analysis and decomposition techniques are used to differentiate between the effects of human capital and labor credentials and the other factors on the socioeconomic gaps between different ethnic and racial groups. The results indicate that there are significant socioeconomic differences both among different Jewish groups and between Jewish and non-Jewish. Moreover the differences among the groups can only partially be explained by the differences in labor credentials of the groups.

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. :-)

Garden with Insight v1.0 Help: Weather next day functions: generate today's solar radiation
This function generates solar radiation for today.
If the "simulated" option for solar radiation is chosen: Today's solar radiation will be
randomly chosen from a normal distribution. The standard deviation for
the normal distribution is calculated from the maximum possible radiation that could reach the earth's
surface today for this climate. The maximum possible radiation depends on the latitude and the day of the
year. The standard deviation is defined as one-quarter of the difference between the maximum possible
radiation and the mean radiation (for today). A number is randomly drawn from a normal distibution having the mean already
calculated for today and this standard deviation. The value is then adjusted for autocorrelation using the autocorrelation matrix.
If the "always 10.0" option for solar radiation is chosen: The solar radiation is set at ten
MJ/m2 (megajoules per square meter). If the "smoothed" option for solar radiation is
chosen: The solar radiation is set at the smoothed long-term
average. The adjustment for yesterday's rain is ignored. If the "unchanging" option for
solar radiation is chosen: The solar radiation stays the same as it was yesterday.

Ottawa, ON, Feb 15, 2012 — One city's relationship with trees is explored in a new museum exhibit in Ottawa.
Six moments in the history of an urban forest is the brainchild of Carleton University history professor Joanna Dean and graduate student Will Knight.
Present-day Ottawa began as rough riverside lumber shanties in the early 1800s. It grew to become the nation's capital, with various trends in tree clearing and tree planting along the way. More recently, the area has faced damage from natural disaster and invasive pests, like the emerald ash borer, which threatens perhaps 30% of Ottawa's existing tree population.
Although the display considers urban forestry from an Ottawa perspective, the challenge of combining trees with cities is universal. Lucy Martin spoke with co-curators, Joanna Dean and Will Knight on opening day at the Bytown Museum, beside the treed slopes of Parliament Hill. Go to full article

A NULL value is possible for a smart pointer. It can be detected via the IsNULL()# function.
|PSmartPointer::PSmartPointer||(||PSmartObject *|| obj =
Create a new smart pointer instance and have it point to the specified PSmartObject# instance.
|obj||Smart object to point to.|
|PSmartPointer::PSmartPointer||(||const PSmartPointer &||ptr||)|
Create a new smart pointer and point it at the data pointed to by the ptr# parameter. The reference count for the object being pointed at is incremented.
|ptr||Smart pointer to make a copy of.|
Destroy the smart pointer and decrement the reference count on the object being pointed to. If there are no more references then the object is deleted.
Determine the relative rank of the pointers. This is identical to determining the relative rank of the integer values represented by the memory pointers.
Reimplemented from PObject.
|PSmartObject* PSmartPointer::GetObject||(||)|| const
Get the current value if the internal smart object pointer.
|PBoolean PSmartPointer::IsNULL||(||)|| const
Determine if the smart pointer has been set to point to an actual object instance.
Assign this pointer to the value specified in the ptr# parameter.
The previous object being pointed to has its reference count decremented as this will no longer point to it. If there are no more references then the object is deleted.
The new object being pointed to after the assignment has its reference count incremented.
|ptr||Smart pointer to assign.|

Serving up smashing spudsNDSU researchers see great potential in colorful potatoes Among the hundreds of potato varieties that North Dakota State University researchers work with, some are certainly eye-catching.
By: Kristen Daum,
Among the hundreds of potato varieties that North Dakota State University researchers work with, some are certainly eye-catching.
Donning vibrant hues of blue, purple and red, specialty spuds stand out from more mainstream varieties like the Russets or Yukon Golds typically found in grocery store displays.
NDSU's potato breeding program began in 1930 with the goal of establishing superior varieties that meet the needs of regional producers in the potato industry.
That includes everything from growing diseaseand pest-resistant varieties to evaluating different types for use in the commercial marketplace, said Asunta "Susie" Thompson, a potato breeder and associate professor at NDSU.
Potato breeders at the university create hybrid varieties by crossing two parent versions, but there's no genetic engineering involved at this time, she said.
The color of a potato's skin and its interior flesh stems from complex genetic coding that's influenced by a specific makeup, she said.
For instance, the purple color means the potato is high in anthocyanins, which are involved in the formation of antioxidants.
Few of the specialty varieties can be found in local grocery stores because widespread availability is still increasing, Thompson said.
Instead, the unique varieties are more easily found in summertime farmer's markets or from specialty growers in the Red River Valley, she said.
The colorful potatoes can also make for festive cooking in the kitchen, no matter how they're served.
"It can really make your plate pop with color and make it fun," Thompson said.
Just don't peel and boil them, Thompson advises.
That can cause the blue or red potatoes to lose their color on the inside, and the food product could potentially turn gray. Instead, the potatoes can be steamed in the microwave to retain the color.
Potatoes are high in nutrients such as vitamin C, potassium, fiber and protein, so the vivid varieties can be helpful alternatives when trying to entice children to eat vegetables.
"It's a great vegetable to have, and kids might be more interested in eating them if they're bright and cheery and colorful," Thompson said.

How to Analyze Results
LabelBlockHE Object
Physical properties of a block for problems of AC magnetics.
The LabelBlockHE object represents physical data applicable to the block label for time-harmonic magnetics problems.
When you need to set or modify some physical parameters for the block label, you have to get the LabelBlockHE object using the Content property of the Label object, modify the LabelBlockHE object using its properties and then put it back in the Label object assigning your LabelBlockHE to the Content property of your Label object.
The LabelBlockHE object inherits methods and properties from its base class LabelBlock. In addition, it provides properties and methods specific for time-harmonic magnetics. Those are:
Kxx (Absolute)
Get and set the components of magnetic permeability.
If the optional parameter is False or omitted, the value is considered as a relative permeability, otherwise as an absolute value.
Absolute values of magnetic permeability are measured in (H/m)
Kxx (Absolute)
Gets and sets the amplitude (peak value) of applying field source for the label.
The exact meaning of the Loading value depends upon two factors:
1. Whether the label describes conductive area (Conductivity > 0), and
2. Whether the TotalCurrent flag is set.
See the Remarks section for more details.
The same as Loading, but allows defining the current (current density, voltage) not only by a value but also by a formula of coordinates.
The phase angle (in degrees) for the Loading value.
Gets and sets the electric conductivity for the label in (S). Conductivity should be positive or zero. Zero conductivity is the case if you don't want to simulate eddy current in this area.
The same as Conductivity, but allows defining the electrical conductivity not only by a constant number but also by a formula of coordinates. The formula should always give a positive result.
Returns/sets the curve representing the dependency of electrical conductivity on temperature.
Returns True when the electrical conductivity depends on temperature and False otherwise.
Returns and sets the temperature value used for calculating the electrical conductivity. It can be either a number or a formula of coordinates. This value is only used when you do not employ importing temperature from a linked problem, or imported values are not available.
Gets and sets the flag modifying the meaning of the Loading value. See the Remarks section for details.
Gets and sets the flag specifies whether the conductors with total current or voltage applied are connected in series. See the Remarks section for details.
Returns an equivalent magnetization curve for AC condition, obtained by recalculating from the source magnetization curve for DC condition.
Following properties set/return the values of the magnetic loss coefficients in the formula of the specific volume losses: p = khf B2 + kcf2B2 + ke(f B)1.5 (W/m3). They are optional. Default zero value of any coefficient defines the zero loss of the corresponding type in the ferromagnetic material.
Sets and returns kh - hysteresis losses per volume unit of given material.
Sets and returns kc - eddy current losses per volume unit of given material. Eddy current losses may be calculated using this formula for materials with zero electrical conductivity (Conductivity or ConductivityEx) in which QuickField does not calculate the eddy currents, yet the eddy current losses should be taken into account. This may be the case for magnetic cores or laminated materials. If the electric conductivity has non zero value and QuickField calculates the eddy current - this coefficient LossEddy in the loss formula should be left with default zero value.
Sets and returns ke - additional losses in the volume unit for given material, which are not taken into account by eddy current and hysteresis losses.
You always have to set both Kxx and Kyy properties even for isotropic materials. If the Polar property is set to True, the Kxx component is considered as a radial and Kyy - as tangential component of the permeability tensor.
Creates a new empty magnetization curve, which can be further used as a parameter for the PutDCSpline method.
Returns the magnetization curve for DC condition (the source curve).
PutDCSpline (
spline as Spline frequency As Double)
Sets the DC (source) magnetization curve and the frequency value for which the curve should be recalculated.
Creates a new empty curve representing the dependency of the electrical conductivity on temperature. Returns a Spline object, which can be assigned to the ConductivitySpline property.
The method of applying sources is different for conductors and non-conductive areas. The table below shows the possible options:
TotalCurrent = True
The Loading is the total number of ampere-turns (in A).
TotalCurrent = False
The Loading is the voltage (in V) applied to conductor's terminals.
The Loading value is the current density (in A/m2)
When the total numbers of ampere-turns of the voltage is applied, you can specify how QuickField should consider several areas labeled with this label (if any). If the Serial flag is set to True, several conductors will be considered as connected in series. Serial conductors are carrying the same current and calculated current density could be different if their squares are not equal.
Please note that with time-harmonic problems you always specify amplitude (peak) values for all alternating quantities.
With nonlinear AC magnetics problem you give a standard magnetization curve for each soft magnetic material. QuickField automatically calculates the magnetization curve for AC condition keeping in mind the problem frequency. The calculated magnetization curve for AC condition is available for reading by the Spline property.
Conductivity depending on temperature
QuickField can take into account the dependency of the electrical conductivity on temperature. You give the dependency by a table, and QuickField automatically approximates it by a cubic spline. When the conductivity depends on temperature, the material is considered as isotropic.
The temperature value used for conductivity calculation is either imported from the linked problem of heat transfer analysis, or given as a number or a formula in the block label (TemperatureEx property). The imported temperature has higher priority.
The Spline object represents the functional dependency of one variable from another. You use the ConductivitySpline property to get or set the conductivity spline. If the spline does not yet exist, the ConductivitySpline property returns Nothing. In that case you have to first create a new spline using the CreateConductivityCurve and then assign the returned object to the ConductivitySpline property.
The NonLinearConductivity property (of Boolean type, read-only) returns True, when the conductivity depends on temperature for this label.
The TemperatureEx property of type Variant sets/returns a priory known temperature in the block given by a number or a formula of coordinates. The formula should always give positive value.

An SQL statement can be preceded by the keyword "EXPLAIN" or by the phrase "EXPLAIN QUERY PLAN". Either modification causes the SQL statement to behave as a query and to return information about how the SQL statement would have operated if the EXPLAIN keyword or phrase had been omitted.
The output from EXPLAIN and EXPLAIN QUERY PLAN is intended for interactive analysis and troubleshooting only. The details of the output format are subject to change from one release of SQLite to the next. Applications should not use EXPLAIN or EXPLAIN QUERY PLAN since their exact behavior is variable and only partially documented.
When the EXPLAIN keyword appears by itself it causes the statement to behave as a query that returns the sequence of virtual machine instructions it would have used to execute the command had the EXPLAIN keyword not been present. When the EXPLAIN QUERY PLAN phrase appears, the statement returns high-level information regarding the query plan that would have been used.
The EXPLAIN QUERY PLAN command is described in more detail here.
The EXPLAIN and EXPLAIN QUERY PLAN prefixes affect the behavior of running a prepared statement using sqlite3_step(). The process of generating a new prepared statement using sqlite3_prepare() or similar is (mostly) unaffected by EXPLAIN. (The exception to the previous sentence is that some special opcodes used by EXPLAIN QUERY PLAN are omitted when building an EXPLAIN QUERY PLAN prepared statement, as a performance optimization.)
This means that actions that occur during sqlite3_prepare() are unaffected by EXPLAIN.
Some PRAGMA statements do their work during sqlite3_prepare() rather than during sqlite3_step(). Those PRAGMA statements are unaffected by EXPLAIN. They operate the same with or without the EXPLAIN prefix. The set of PRAGMA statements that are unaffected by EXPLAIN can vary from one release to the next. Some PRAGMA statements operate during sqlite3_prepare() depending on their arguments. For consistent results, avoid using EXPLAIN on PRAGMA statements.
The authorizer callback is invoked regardless of the presence of EXPLAIN or EXPLAIN QUERY PLAN.

Let's suppose that a flight is being conducted under 14 CFR 135. The airplane is certified for single pilot operations, but two pilots who are both rated as PIC on the 135 certificate occupy the pilot seats. One of the pilots is a CFI. Does anything in 14 CFR 135 prevent the CFI from giving dual given time to the PIC while he flies?
 - 1
 $\begingroup$ Sounds like a 135 operator conducting type transition training to me... $\endgroup$ – UnrecognizedFallingObject Dec 18 '15 at 4:58
 - $\begingroup$ I'm not asking the question in that specific context, but that would apply. I'm asking if anything prevents instruction from being given during operations with passengers or cargo while operating under 14 CFR 135. $\endgroup$ – ryan1618 Dec 18 '15 at 14:15

 $\begingroup$ _USER_ feel free to make that kind of edit yourself too... $\endgroup$ – Bret Copeland Jan 1 '16 at 21:51
It took me a little bit to figure out the underlying reason for asking this question and it has to do with logging flight time. For example, in a single pilot operation with an autopilot, the second pilot is not required and therefore cannot log the flight time at all even though their company may want them there. The FARs don't allow the second pilot to log the time.
The regulation that governs logging of flight time is 61.51.
61.51(h) Logging training time. (1) A person may log training time when that person receives training from an authorized instructor in an aircraft, flight simulator, or flight training device. (2) The training time must be logged in a logbook and must: (i) Be endorsed in a legible manner by the authorized instructor; and (ii) Include a description of the training given, the length of the training lesson, and the authorized instructor's signature, certificate number, and certificate expiration date.
So the question becomes what training was given during the revenue Part 135 flight and were you an authorized instructor?
The term Authorized Instructor is only found in Part 61.
61.1. Authorized instructor means— (i) A person who holds a ground instructor certificate issued under part 61 of this chapter and is in compliance with §61.217, when conducting ground training in accordance with the privileges and limitations of his or her ground instructor certificate; (ii) A person who holds a flight instructor certificate issued under part 61 of this chapter and is in compliance with §61.197, when conducting ground training or flight training in accordance with the privileges and limitations of his or her flight instructor certificate; or (iii) A person authorized by the Administrator to provide ground training or flight training under part 61, 121, 135, or 142 of this chapter when conducting ground training or flight training in accordance with that authority.
Since it is a Part 135 revenue flight I would believe the CFI would have to comply with section 135.338 and 135.340.
135.340(a) No certificate holder may use a person nor may any person serve as a flight instructor unless— (1) That person has satisfactorily completed initial or transition flight instructor training; and (2) Within the preceding 24 calendar months, that person satisfactorily conducts instruction under the observation of an FAA inspector, an operator check airman, or an aircrew designated examiner employed by the operator.
If the authorized instructor has complied with 135.338 and 135.340 they are also bound to the training program for the 135 company. If that training stipulates you can give dual given during revenue flights than you are more than welcome to do so. If there is no provision in the training program to provide instruction during revenue flight then it should not be done.
The best option is to request a legal interpretation on the validity of what you are wanting to do.
Short answer: NO
Long answer: In a flight where the CFI is certificated to provide instruction and the two are sitting in pilot seats then the PIC may log any part of that flight as dual instruction. It does not require the CFI to actually say a word in order for it to count as dual; even if he's merely observing, if something bad happens he'll open his mouth or take controls.
Part 135 is more about requirements for operations; it does not affect flight instruction, which is a part 91 regulated activity.
 - 2
 $\begingroup$ Nothing here gives any explanation why "no" is the correct answer to the question "Can instruction be given during a {Part 135 flight}?" Are you answering the question "does anything in Part 135 prevent..."? $\endgroup$ – Ralph J Jan 1 '16 at 2:00
 - $\begingroup$ You can't log training time unless a CFI endorses your logbook, per 61.51(h), so there's more to it than just being in the aircraft together (related question). And I assume that in your last sentence you meant to say that flight instruction is regulated by part 61 (not part 91)? $\endgroup$ – Pondlife Jan 2 '16 at 1:54
Your Answer


Understanding Horizontal Cantilever Gate Trusses
What is a horizontal cantilever gate truss? It is a single plane truss very similar to a building truss. Relative to cantilever gates, it is a rigid frame made from smaller tubing. It may be integrated into the gate frame at time of fabrication or it can be a standalone truss with a complete frame that can be mechanically fastened to the gate in the field.
The illustrations below demonstrate a truss system that is integrated into the gate fabrication. If you review the 35'+ truss, it may be viewed as both a truss integrated into the gate or a standalone.
Why would you use a standalone truss?
 - The most practical reason would be for ease of transportation. More than likely, these trusses are used because it was not considered necessary initially at the time of fabrication or the gate was originally manual and ended up becoming automated.
When would you use a horizontal truss?
 - A cantilever gate requires a truss when it reaches in excess of 24' opening and is automated. Please refer to the lengths shown below in the illustrations.
Is a horizontal truss the best solution?
 - No. If a gate is to be automated and reaches the lengths below, the best application is a double track aluminum cantilever gate. These gates effectively deal with the wind load with their widened profile and the combination of the double tracks.
What is the biggest concern with a horizontal truss?
 - These trusses are not supported by ASTM 2200 as they protrude out too far from the gate frame, posing a hazard to pedestrians. Please note that none of the illustrations below show a blunt end to the truss. All are designed with an eased-sloped end so that it may cause less harm if it comes in contact with others.
Need a better solution for existing gates that won't provide for a horizontal truss? American Fence Company has your solution. Please refer to the illustration below with the opposing cable truss design. This is a cable truss system that has a very thin profile. A tube is attached to both sides of the gate at the midpoint that horizontally runs the length of the gate. The tube is a carrier for the cable. A cable is installed in each tube with the cable anchored on one end and anchored on the other end with a turnbuckle-style tightener. The cables are tensioned equally, creating an opposing force against one another. As these forces build, the gate will gain rigidity. This is very similar to the concept in post tensioned concrete. This is an exclusive American Fence Company design.

Hi alexandertg6! Welcome to PF!
a uniform beam of length 12.0 m is supported by a horizontal cable and a hinge at angle θ = 70° with the vertical. The tension in the cable is 500 N. Find the gravitational force on the beam in unit vector notation and the force on the beam from the hinge in unit vector notation.
T =.5(horizontal distance) ( gravity) (mass)/ vertical distance
500 = (.5(9.8)(12sin70)m)/(12cos70)
hmm … you've taken moments about the hinge
but what's 12sin70º?

ECU geography poster details hurricane phenomena
(Dec. 4, 2003)
A poster about the particulars of hurricanes was developed this year by East Carolina University's Department of Geography and the student organization Geoclub. The poster, "Tempests from the Tropics: Atlantic & Gulf Coast Hurricanes," was produced by ECU students as part of an annual project designed to educate the public about issues in current events. The free map will be available in area schools, public libraries and Barnes & Noble Booksellers.
In the past two years, faculty and students worked together to produce and distribute map posters on Afghanistan and Iraq, respectively. This year, the group chose to design an informational poster on hurricanes because of the traumatic impact that these events have on life in North Carolina.
"This is particularly the case in light of the continuing aftermath of Hurricane Floyd in 1999 and the more recent damage caused by Hurricane Isabel in 2003," said ECU Geography professor Derek Alderman.
Made with state of the art geospatial data and technology, the poster contains graphic illustrations and photographs and explains how hurricanes form, how much death and property damage they can cause, how they are named and why hurricanes take the unique geographic path they do toward North Carolina.

Cocoon Source Resolving
Differences between Cocoon and Avalon Excalibur Source Resolving
This story tries to list the changes between the two source resolving approaches. Originally, the source resolving was developed in the Cocoon community. As the community recognized that it had a more common value, the source resolving was donated to the Avalon Excalibur project and there it was refined and redesigned. Now the way back takes place by reintegrating the Avalon Excalibur Source Resolving into Cocoon and deprecating the now obsolete Cocoon Source Resolving.
The Interfaces
Besides the package names the main difference is that the Cocoon Source object is XMLizable, that means it can directly send SAX events. The AE Source object is not XMLizable, which is more correct as a protocol only describes the way of transport but not the format of the data which is transfered. Therefore it provides a getMimeType() method.
The Cocoon Source object returns a last modified time stamp which is very limiting. For example a source could have an expires date or something like that. The AE Source returns a validity object which is capable of all these validity checkings. So the information used for validity checking is provided by the source object and not maintained by the client of the source as it is currently in Cocoon.
As we in Cocoonland are dealing a lot with XML, a Source implementation can still implement the XMLizable Interface (from AE and not from Cocoon!) to directly provide SAX events. The Cocoon SourceUtil class has a method toSAX() which gets a Source object and tests if it implements the XMLizable interface. If not the new AE XMLizer is used which is a component that can convert an input stream with a given mime-type to SAX events. This component is configurable and extensible.


text: Measuring long-term care (LTC) outcomes is challenging – not only conceptually but also in terms of implementation. The aim of this presentation is to discuss three examples for LTC outcome measurement based on ASCOT in Austria. The first example will deal with the Home Visit and Counselling Programme run by the Austrian Ministry of Social Affairs. It will show how outcomes for a very large number of care recipients can be assessed by a mix of methods and what needs to be considered to obtain reliable results. The second example illustrates how LTC outcomes are used for supervising home care service provision in Vienna. Finally, a qualitative study of outcomes in day care centres in Vienna demonstrates that it is more than just being in company or occupied that people could gain from such services. Taken together these three examples provide insights into processes and results of LTC outcome measurement and discuss further options for development and implementation.

Using a Tiny Cutting Board
Why it's bad: You won't have room to maneuver a knife, which increases your risk of cutting yourself. You'll also make a mess and waste time corralling ingredients that fall off the board.
Do this instead: Think small knife, small board; big knife, big board. You can use a little board for a quick task, like cutting a lemon into wedges with a paring knife. But since most kitchen prep work requires a chef's knife, you probably need a board that is at least 12 by 15 inches. It should be large enough to hold ingredients at every stage of the process. For example, if you're chopping celery, you want room for both the stalks you start with and the pile of cut pieces you end up with. Before you begin, place a damp paper towel or dishcloth underneath the board to prevent it from slipping around on the counter.


Multiple Animations
Just before WWDC I answered an interesting question on Stack Overflow asking where to update the model value when following Core Animation best practices. It may sound like a simple question but it touches on deep topics like implicit vs. explicit animations, stand-alone vs. backing layers, and multiple animations. I'm not going to reiterate the whole question and answer here, but I'm going to start with the same question. The original question and answer still contain useful information, so if you are interested I can recommend it as a complement to this post.
Let's start with some quick background to get everyone on the same page. Not removing an animation after it finishes is considered bad practice. I've written about it in the context of clear code and a follow-up gist explaining why I don't think there is any reason to do it. There are plenty of people in the community that also talk about it, so I hope that we can all accept that it is a bad practice and start doing it "the other way".
The "other" way is to update the model value by setting the property being animated to its final value. This means that once the animation finishes and is removed, the model both is and appears to be in the correct state. The question then is: where exactly is it best practice to update the value when adding an animation? Before creating the animation? Before adding the animation to the layer? Or after adding the animation to the object?
// 1. Before configuring the animation?
var myAnimation = CABasicAnimation(keyPath: "position.x")
myAnimation.fromValue = oldValue
myAnimation.toValue = newValue
myAnimation.duration = 1.0
// 2. Before adding the animation?
view.layer.addAnimation(myAnimation, forKey: "move to the right")
// 3. After adding the animation?
The only meaningful distinction to Core Animation is whether the model is updated before or after adding the explicit animation, so from that perspective, the first and second case can be treated as one case: the "before" case. Exactly where before adding the animation that the model is updated only affects how the animation values are configured. If the model is updated before configuring the animation, the old state might need to be saved first, so that the animation can be configured to animate from the old state to the new state. Since there is no real technical difference between the two cases (1 and 2), we should only optimize for clarity. I usually find that code that configures the animation before updating the model is easier to follow but there are cases where the opposite is true. In the end it comes down to personal preference.
That leaves us with only two cases to compare: before adding the animation and after adding the animation. This is when things start to get interesting. Depending on if we are animating a stand-alone layer or a backing layer (a layer that is attached to a view), we will see some differences between the before and after cases. This has to do with the way that layers implicitly animate property changes and the way that views disable this default layer behavior. Before explaining the difference between the two, let's look at what an implicit animation is and what the default layer behavior is.
When a layer property changes, the layers looks for an appropriate "action" to run for that change. An action is an object that conforms to the CAAction protocol. In practice, it's going to be a subclass of CAAnimation. The steps that the layer takes to look for the action is described in detail in the documentation for the actionForKey: method on CALayer.
The layer starts by asking its delegate which can return with one out of three things:
 1. An action to run
 2. nil to keep looking
 3. NSNull to stop looking
Next, the layer looks for the property as the key in its actions dictionary. It can end up in one out of three cases:
 1. An action to run is found for that key.
 2. That key doesn't exist, telling the layer to keep looking.
 3. NSNull is found for that key, telling the layer to stop looking.
After that the layer looks for an actions dictionary in the style dictionary (something that I've never used myself or seen any other developer use). It then checks if there are any specific actions for that class by calling defaultActionForKey:. If no action if found the layer uses the implicit action that is defined by Core Animation.
In the normal case, we end up with the implicit animation. This animation object is then added to layer, using the addAnimation:forKey: method, just like we would add an animation object ourselves. This all happens automatically, just by changing a property. Hence the name: implicit animation.
The important part to take away is that when a property of a stand-alone layer changes, an animation object is added to the layer automatically.
For layers that are attached to views, things work differently. Every view on iOS has a backing layer and the view is always the layers delegate. This means that when the property changes, the view has first say for whether an animation should run or not. As we all know, views don't implicitly animate. This is because the view returns NSNull when asked to provide an action (except when inside of an animation block). You can read more about this interaction between the view and its backing layer in my article.
Getting back to updating the model and adding an explicit animation. In the case of the backing layer, the property change doesn't cause an animation so it doesn't matter if the layer is updated before or after adding the explicit animation. There is only going to be one animation anyway.
For the stand alone layer however, the property change causes and implicit animation to be added and we are adding an explicit animation so the layer ends up with two animations at the same time! This leads us to the next very interesting and deep topic: multiple animations.
Multiple animations
It's no surprise that different properties can be animated at the same time but multiple animations for the same property‽ Surely one must cancel out the other. Well, that is actually not the case. An animation is only canceled if another animation is added for the same key. So both animations are added to the layer, in order, and run until they are finished. It's easy to verify by becoming the delegate of both the implicit and explicit animation and logging the "flag" in the animationDidStop:finished: callback. Another, more visual way to see that both animations are running is to see how the animation looks in the two cases. If the model is updated first, then only the explicit animation can be seen. However, if the model is updated last so that the implicit animation added last, then the implicit animation can be seen running until completion and then the layer continues with the explicit animation as if it was running all along.
The two different animations when updating the model before and after adding the explicit animation.
There are two things to note in the above figure:
 1. When the implicit animation completes, the layer doesn't skip back to the beginning of the explicit animation.
 2. In both cases the explicit animation end after the same amount of time.
To better understand what is happening it is best to look at how the animation is rendered.
Disclaimer: I don't work at Apple and I haven't seen the source code for Core Animation. What I'm about to explained is based on information available in documentation, WWDC videos, or information based on observations and experimentation.
The animation object is created and configured by our application but the application process is not doing the actual rendering. Instead the animation is encoded together with a copy of the layer hierarchy and send over inter-process communication to the render server (which is part of the BackBoard daemon). With both a copy of the layer tree (called the "render tree") and the animations, the render server can perform each frame of the animation without having to communicate back and forth with our application process all the time.
For each frame the render server calculates the intermediate values for the animated properties for the specific time of that frame and applies them to the layers in the render tree.
If there are multiple animations going on at the same time, they are all sent to the render server and all of their changes are applied to the render tree for each frame being rendered. If there are two (or more) animations for the same property, the first will apply its intermediate value and the next will apply its intermediate value on top of that, overwriting the first value. Even animations that are completed but not removed apply their changes to the layers in the render tree, leading to some unnecessary overhead.
Knowing this, our two cases with the order of the implicit and explicit animations can be explained and visualized as follows.
In both cases the model value is changed to its new value at the start of the animation. It doesn't matter if it happens before or after the explicit animation, the model value is updated in the copy of the layer tree that gets sent to the render server.
For the case where the model is updated first, the implicit animation is added to the layer first and the explicit animation is added after that. Since the implicit animation is much shorter than the explicit animation, the intermediate values ii applies to the render tree is always overwritten by the intermediate values of the explicit animation. After a short while, the implicit animation finishes and is removed and the explicit animation runs alone until it finishes, applying its intermediate values directly over the model values. When the explicit animation finishes, it gets removed and we are left seeing the model values (which matches the end value of the explicit animation). The result looks like a smooth animation from the old value to the new value and the implicit animation is never seen.
Note: there may be implementation details

Bet without Looking: Studying Eyes-Free Interaction During Live SportsAbstract:
This paper presents a comparison study of three different interaction methods for an eyes-free interaction with a second screen application while watching a TV broadcast. These interaction methods were used in WeBet, a touch-based mobile game that prompts users to bet if a goal is about to happen during a football match. WeBet is one of the prototypes we have been developing to increase the remote users' emotional levels during live sports broadcasts, so that they feel like if they were scoring a goal with their team. However, that can only be achieved if the second screen application does not require the users' attention when a goal (key moment) is just about to happen, otherwise they would be frustrated to miss that exciting moment. To this end, we conducted user tests that allowed us to determine the usage patterns and users' preferences regarding three different interaction methods, as well as to identify important refinements to be considered in future developments.

A number of protocols for working with Indigenous communities and Indigenous culture and heritage have been developed. The protocols provide a best practice model for artists.
It is important to be aware that Indigenous protocols cannot answer all the questions you may be faced with, as every Indigenous community, organisation and individual is different. However, Indigenous protocols are an excellent resource as they provide:
- a starting point for solving problems,
- a set of guidelines and principles to help you think about a project or the nature of collaboration,
- questions to ask the Indigenous participants, and
- legal and non-legal issues to be considered.
There are a number of different types of Indigenous protocols:
- Protocols for artists and those working with them
- Protocols for arts dealers
- Protocols and information for consumers
- Protocols for cultural institutions
- Protocols for the media
- Protocols for language projects
The Australia Council for the Arts published a set of Indigenous protocol guides in 2002, written by Indigenous lawyers Robynne Quiggin and Terri Janke. Those protocols provide information and advice on respecting Indigenous culture and heritage.
There are five sets of protocols specific to the following Indigenous art forms:
Arts Tasmania - Respecting Cultures, Working with the Tasmanian Aboriginal Community and Aboriginal Artists
This publication provides a specific Tasmanian perspective as a companion text for the Australia Council's protocols. Respecting Cultures promotes greater awareness of the protocols needed to ensure that Aboriginal artists are acknowledged and their intellectual property and culture is respected and protected.
National Association for the Visual Arts – Valuing Art, Respecting Culture: Protocols for Working With the Australian Indigenous Visual Arts and Craft Sector
This document sets out protocols both to guide non-Indigenous people in their relationships with Indigenous artists and communities, and assist Indigenous artists to define their rights.
The IAACCC is a voluntary code to regulate the conduct of participants in the Indigenous art industry. Its main aims are to ensure fair and ethical trade with artists, transparency with the promotion and sale of artwork as well as a fair and equitable dispute resolution system for disputes arising under the code. The Indigenous Art Code Limited, a public company, was founded to administer the IAACCC.
The City of Melbourne has developed a code of practice for galleries and retailers of Indigenous art. The code is a guide outlining ethical and appropriate ways to display and sell authentic Indigenous art and work with Indigenous artists.
National Indigenous Consumer Strategy - Taking Action, Gaining Trust: National Indigenous Consumer Strategy – Action Plan 2010-2013
The National Indigenous Consumer Strategy (NICS) was developed by the Standing Committee of Officials of Consumer Affairs (SCOCA), who represents all the Commonwealth, State and Territory government consumer protection agencies. The NCIS aims at improving the consumer outcomes of Indigenous Australians by encouraging consumer protection agencies to share information and education materials, collaborating in the enforcement of consumer rights and laws, and co-ordinating research, policy development and consumer education initiatives. The NCIS was originally created in 2005 as a three year strategy. However an updated action plan for 2010-2013 has recently been developed.
Australian Government, Department of Environment and Heritage – Welcome to Country: Respecting Indigenous Culture for Travellers in Australia
This information brochure is aimed at providing travellers in Australia with some key protocols to follow in order to ensure respect for Indigenous culture. It is framed around three main principles:
- Relationship – Recognise Indigenous people's relationship and connection to the land.
- Responsibility – Acknowledge the ongoing responsibility Indigenous people have to their country, and recognise your own responsibility to travel thoughtfully.
- Respect – Respect Aboriginal beliefs associated with country and culture. As a visitor, respect the wishes of your hosts and and restrictions that you have been asked to observe.
These resource guidelines are aimed at assisting cultural institutions in developing links with the broader community. They are intended to be used to support non-Indigenous cultural heritage workers in small museums throughout Australia who wish to work with culturally diverse communities, including Indigenous communities.
Aboriginal and Torres Strait Islander Library and Information Resources Network (ATSILIRN) – Aboriginal and Torres Strait Islander Protocols for Libraries, Archives and Information Services
The ATSILIRN Protocols are intended to guide libraries, archives and information services in appropriate ways to interact with Aboriginal and Torres Strait Islander people in the communities which the organisations serve, and to handle materials with Aboriginal and Torres Strait Islander content.
They are a guide to good practice which will need to be interpreted and applied in the context of each organisation's mission, collections and client community.
Intellectual Property Research Institute of Australia (IPRIA) - Cultural Institutions, Law and Indigenous Knowledge: A Legal Primer on the Management of Australian Indigenous Collections
This document examines some of the legal issues which arise for cultural institutions and other bodies in the acquisition, use and reproduction of Aboriginal and Torres Strait Islander cultural material. The term 'cultural material' is used broadly to refer to collection items that reproduce, record or depict Indigenous people, cultures, knowledge and experiences; in some cases, this is highly sensitive of restricted information. It includes artistic outputs and archival research material.
Australian Institute for Aboriginal and Torres Strait Islander Studies (AIATSIS) - Guide for Ethical Research in Indigenous Studies
The AIATSIS guidelines provide recommendations and suggestions for achieving the best standards of ethical research in Indigenous studies. The document is laid out with a series of principles, which are accompanied by a brief definition and some practical applications.
Australian National Maritime Museum (ANMM) - Connections: Indigenous Cultures and the Australian National Maritime Museum
The ANMM's Indigenous protocols provide guidance on Indigenous issues that can impact on museum programs and procedures. It aims to help the ANMM and other institutions interpret Indigenous cultures authentically and respectfully.
Museums Australia – Continuing Cultures, Ongoing Responsibilities: principles and guidelines for Australian Museums working with Aboriginal and Torres Strait Islander cultural heritage.
The Continuing Cultures, Ongoing Responsibilities document is intended to guide museums and galleries in framing their own procedures for dealing with Aboriginal and Torres Strait Islander peoples and the management of their cultural heritage.
The Collections Australia guide provides a practical tool for land developers, land users and managers, cultural heritage professionals and many others who may have an impact on Indigenous heritage. This title – 'Ask First' is intended to highlight the guides focus on consultation and negotiation with Indigenous stakeholders as being key to addressing heritage issues.
Screen Australia (Terri Janke) – Pathways and Protocols: A filmmaker's guide to working with Indigenous people, culture and concepts
Screen Australia's guide provides comprehensive information for all filmmakers working with Indigenous content and communities, providing advice about the ethical and legal issues involved when transferring Indigenous cultural material to the screen. The guide includes information on documentary and drama productions, including short dramas, feature films and television drama. Drawing upon real case studies as practical examples, the guide assists and encourages recognition and respect for the images, knowledge and stories of Indigenous people.
This protocol is for Aboriginal and Torres Strait Islander communities and their consultants working together to produce language materials, for example linguists, schools and ICT (Information and Communication Technologies) specialists. The FATSIL guide covers protocols for producing language materials at a local level, rather than through one of the major publishing houses.
The aim of this protocol is to encourage positive working relationships between Aboriginal and Torres Strait Islander communities and their consultants. Any language materials produced should recognise the cultural and intellectual property rights of the language community. The FATSIL protocol accompanies, and should be read in conjunction with, the model language agreement prepared by the Arts Law Centre of Australia


U'} \simeq G_{U'}$ whose specialization at any $g' \in U'(k)$ is right-translation on $G$ by the corresponding point $g \in U(k)$. Suppose ${\rm{char}}(k) = 0$, so $U' = U$ and the composite morphism $${\rm{pr}}_1 \circ \rho:G \times U \rightarrow G$$ on $k$-points is the group law restricted to $U(k)$ in the 2nd variable. For any $g \in G(k)$ the right translation morphism $\rho_g$ carries $U$ to another open subscheme $\rho_g(U)$, and I claim that these opens cover $G$. It suffices to check the covering property on $k$-points, so for $h \in G(k)$ we seek $g \in G(k)$ such that $h \in \rho_g(U)$, or equivalently $hg^{-1} \in U(k)$. Pick any $u \in U(k)$ and let $g = u^{-1}h$. This proves the covering property, and the multiplication map $G(k) \times U(k)g \rightarrow G(k)$ arises from a morphism, namely the composition of ${\rm{pr}}_1 \circ \rho$ and the morphism $\rho_g$. We conclude (in char. 0) that the group law on $G(k)$ is induced by a morphism $G \times G \rightarrow G$.
Now we can deduce in char. 0 that inversion is a morphism (so we have a group variety), even though we never used the left-translation or inversion conditions. Indeed, the "universal right-translation" $G \times G \rightarrow G \times G$ defined by $(x,y) \mapsto (xy,y)$ between fppf $G$-schemes (via ${\rm{pr}}_2$) is a scheme isomorphism between fibers over all points in $G(k)$ and therefore is a scheme isomorphism (by fibral isomorphism criteria, adapted to the peculiarities of $k$-points when $k$ is alg. closed). This yields the morphism property for inversion for free! This was a char-free argument, but it required the composition law to be a morphism. Anyway, char. 0 is now settled.
Assume ${\rm{char}}(k) = p > 0$, so for sufficiently large $n \ge 0$ the finite flat $n$-fold relative Frobenius morphism $G^{(1/p^n)} \rightarrow G$ of $G^{(1/p^n)}$ dominates $U'$ over $U$ (namely, pick $n \ge 0$ so that the finite purely inseparable extension $F/k(G)$ is contained inside $k(G)^{1/p^n}$). Since the initial choice of $F$ could be replaced with a finite purely inseparable extension at the outset if we wish, we may therefore assume that $U'$ is open inside $G^{(1/p^n)}$. Using a covering and translation argument similar to characteristic 0, we arrive at a morphism $$m_r:G \times G^{(1/p^n)} \rightarrow G$$ that recovers the given group law on $k$-points via the natural identification of $G^{(1/p^n)}(k)$ with $G(k)$ (for some $n \ge 0$). Our problem is precisely to show that $m_r$ factors (in the sense of morphisms of varieties) through the $n$-fold relative Frobenius morphism in the 2nd variable.
Now we shall use that left-translations are morphisms too. At the cost of increasing our $n$ if necessary, we can run through the same arguments with "left" instead of "right" to arrive at another morphism $$m_{\ell}:G^{(1/p^n)} \times G \rightarrow G$$ which recovers the given group law on $k$-points (with the same $n$).
Returning to our task of checking that $m_r$ factors through the appropriate iterated Frobenius in the 2nd variable, since that iterated Frobenius is fppf (as $G$ is smooth!) we conclude via fppf descent that it is harmless to check the existence of such a factorization after precomposing $m_r$ with an fppf morphism in the first variable. So let's compose with the same iterated Frobenius in the first variable, arriving at a morphism $$G^{(1/p^n)} \times G^{(1/p^n)} \rightarrow G$$ that recovers the composition law of $G(k)$ on $k$-points. It suffices to show that this latter map factors through the $n$-fold Frobenius in its 2nd variable, but this factorization is clear: it is the composition of $m_{\ell}$ with that iterated Frobenius (as we may check by computing on $k$-points, since we're working with reduced $k$-schemes of finite type).

What kinds of applications are there for using a ruby ball probe tip?
A ball-tipped probe is most often used to assess the flatness of a surface, also known as scanning. By using a ruby ball probe, you are harnessing each of the advantages of ruby as a material—sphericity, hardness, smoothness, and resistance. Scanning is used in order to identify any flaws that a material might have. A ruby ball probe is used to measure the individual imperfections that are found during the scanning process. By running the probe across the surface of interest, you can find and measure the size of any flaws that exist. Ensuring smoothness and perfect sphericity of the ball on your probe is pivotal to successful scanning. Ruby is the best choice for this purpose since it is reliably spherical and smooth, as well as difficult to damage.

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?

On joy and learning
At Haiti Partners, it's important to us to present not only Haiti's harsh realities, but its beautiful sides as well. In videos like the one below, we celebrate the joy of happy students having fun with one of their favorite people, Children's Academy Coordinator, Alex Myril.
But making our students feel safe and happy isn't just about having fun. It's essential to successful learning. Research shows that stress impedes memory and learning. In order for children to engage and develop to their potential, they need to feel safe and cared for. And, unfortunately, stress is the norm in all too many schools in Haiti where corporal punishment and humiliation are used regularly in the classroom.
Thank you for your partnership as we work to make high quality, transformative, joyous education the norm in Haiti.


There's a good chance that if you've walked around in any city, you've passed by defensive architecture. It's all around us and it shapes the fabric of the city—which is why it's important to understand what defensive architecture is. According to Toronto-based urban planning researcher Cara Chellew, "Defensive urban design, also known as hostile, unpleasant, or exclusionary architecture is a type of persuasive design used to guide behaviour in urban space by designing out specific uses of street furniture or the built environment as a form of crime prevention or protection of property" (Chellew, "About"). In other words, defensive or hostile architecture is architecture designed to limit the ways in which a space can be used. These subtle design implementations act as miniature zoning laws that dictate appropriate uses of public space. Our goal is to educate people on what hostile architecture looks like and who it impacts.
 What does defensive architecture mean, why does it exist, and what challenges does it bring?

HomeDefinitionsCareer DictionaryLoudermill Rights
Loudermill Rights
The term Loudermill Rights refers to those due process requirements that are followed when a tenured public employee is involuntarily terminated. Loudermill Rights are based on a U.S. Supreme Court decision: Cleveland Board of Education v. Loudermill (1985).
Tenured public employees were granted Loudermill Rights following a Supreme Court decision, which determined that most public employees have a property interest in their job. For this reason, they are afforded due process rights before removing or impacting their property interest in their job. This "property right" means non-probationary public employees can only be terminated for cause. They may also be entitled to certain rights in cases of severe discipline.
Generally, the following steps are followed when a tenured public employee is involuntarily terminated:
 1. Loudermill Letter: employees are entitled to proper notice, indicating why they are being fired as well as any specific evidence supporting the employer's decision to terminate the employee. The letter will also inform the employee of their right to a hearing.
 2. Pre-Termination Hearing: also referred to as a Loudermill Hearing, this is a relatively informal meeting that provides an opportunity to determine if there are reasonable grounds to terminate after the employee addresses the evidence of the case. Individuals attending this meeting typically include the employee, their direct supervisor, a member of the human resources department, and a union representative.
 3. Post-Termination Hearing: if the employee is subsequently terminated, they are entitled to a full evidentiary hearing. The purpose of this meeting is to verify the facts presented against the employee, and whether or not the involuntary termination is justified.
Note: If the employee does not attend the pre-termination hearing, the employer can still proceed with termination.
