not a power of 6.
n_start => $n option can select a different initial N. The tree structure is unchanged, just the numbering shifted. As noted above the default Nstart=0 corresponds to powers in a generating function.
n_start=>1 makes the numbering correspond to digits of N written in base-k. For example k=10 corresponds to N written in decimal,
N=1 to 9 1/2...... 2/1 N=10 to 99 1/4 4/7...... 7/4 4/1 N=100 to 999 1/6 6/11...... 11/6 6/1
n_start=>1 makes the tree
N written in base-k digits depth = numdigits(N)-1 NdepthStart = k^depth = 100..000 base-k, high 1 in high digit position of N N-NdepthStart = position across whole row of all top trees
And the high digit of N selects which top-level tree the given N is under, so
N written in base-k digits top tree = high digit of N (1 to k, selecting the k-1 many top nodes) Nrem = digits of N after the highest = position across row within the high-digit tree depth = numdigits(Nrem) # top node depth=0 = numdigits(N)-1
Chan shows that each denominator Y becomes the numerator X in the next point. The last Y of a row becomes the first X of the next row. This is a generalization of Stern's diatomic sequence and of the Calkin-Wilf tree of rationals. (See Math::NumSeq::SternDiatomic and "Calkin-Wilf Tree" in Math::PlanePath::RationalsTree.)
The case k=2 is precisely the Calkin-Wilf tree. There's just one top node 1/1, being the even k "middle" form h/h with h=k/2=1 as described above. Then there's two children of each node (the "middle" pair of the even k case),
k=2, Calkin-Wilf tree X/Y / \ (1X+0Y)/(1X+1Y) (1X+1Y)/(0X+1Y) = X/(X+Y) = (X+Y)/Y
See "FUNCTIONS" in Math::PlanePath for behaviour common to all path classes.
$path = Math::PlanePath::ChanTree->new ()
$path = Math::PlanePath::ChanTree->new (k => $k, n_start => $n)
Create and return a new path object. The defaults are k=3 and n_start=0.
$n = $path->n_start()
Return the first N in the path. This is 0 by default, otherwise the
$n = $path->xy_to_n ($x,$y)
Return the point number for coordinates
$x,$y. If there's nothing at
Each point has k children, so the path is a complete k-ary tree.
_USER_ = $path->tree_n_children($n)
Return the children of
$n, or an empty list if
$n < n_start(), ie. before the start of the path.
$num = $path->tree_n_num_children($n)
Return k, since every node has k children. Or return
$n < n_start(), ie. before the start of the path.
$n_parent = $path->tree_n_parent($n)
Return the parent node of
$nhas no parent either because it's a top node or before
$n_root = $path->tree_n_root ($n)
Return the N which is root node of
$depth = $path->tree_n_to_depth($n)
Return the depth of node
undefif there's no point
$n. The tree tops are depth=0, then their children depth=1, etc.
$n = $path->tree_depth_to_n($depth)
$n = $path->tree_depth_to_n_end($depth)
Return the first or last N at tree level
$depthin the path. The top of the tree is depth=0.
$num = $path->tree_num_roots ()
Return the number of root nodes in
$path, which is k-1. For example the default k=3 return 2 as there are two root nodes.
_USER_ = $path->tree_root_n_list ()
Return a list of the N values which are the root nodes of
$path. This is
n_start()+k-2inclusive, being the first k-1 many points. For example in the default k=2 and Nstart=0 the return is two values
$num = $path->tree_num_children_minimum()
$num = $path->tree_num_children_maximum()
Return k since every node has k many children, making that both the minimum and maximum.
$bool = $path->tree_any_leaf()
Return false, since there are no leaf nodes in the tree.
For the default k=3 the children are
3N+2, 3N+3, 3N+4 n_start=0
n_start=>1 then instead
3N, 3N+1, 3N+2 n_start=1
n_start=1 the children are found by appending an extra ternary digit, or base-k digit for arbitrary k.
k*N, k*N+1,..., k*N+(k-1) n_start=1
In general for k and Nstart the children are
kN - (k-1)*(Nstart-1) + 0... kN - (k-1)*(Nstart-1) + k-1
The parent node reverses the children calculation above. The simplest case is
n_start=1 where it's a division to remove the lowest base-k digit
parent = floor(N/k) when n_start=1
n_start adjust before and after to an
parent = floor((N-(Nstart-1)) / k) + Nstart-1
For example in the default k=0 Nstart=1 the parent of N=3 is floor((3-(1-1))/3)=1.
The post-adjustment can be worked into the formula with (k-1)*(Nstart-1) similar to the children above,
parent = floor((N + (k-1)*(Nstart-1)) / k)
But the first style is more convenient to compare to see that N is past the top nodes and therefore has a parent.
N-(Nstart-1) >= k to check N is past top-nodes
As described under "N Start" above, if Nstart=1 then the tree root is simply the most significant base-k digit of N. For other Nstart an adjustment is made to N=1 style and back again.
adjust = Nstart-1 Nroot(N) = high_base_k_digit(N-adjust) + adjust
The structure of the tree means
depth = floor(logk(N+1)) for n_start=0
For example if k=3 then all of N=8 through N=25 inclusive have depth=floor(log3(N+1))=2. With an
n_start it becomes
depth = floor(logk(N-(Nstart-1)))
n_start=1 is the simplest case, being the length of N written in base-k digits.
depth = floor(logk(N)) for n_start=1
This tree is in Sloane's Online Encyclopedia of Integer Sequences as
k=3, n_start=0 (the defaults) A191379 X coordinate, and Y=X(N+n)
As noted above k=2 is the Calkin-Wilf tree. See "OEIS" in Math::PlanePath::RationalsTree for "CW" related sequences.

On 04 May 2023, Ambassador Cecilia Attard-Pirotta, accompanied by First Secretary at the Embassy Mr Charles Calleja, paid a visit to the offices of Mano Maritime in Haifa to learn more about the company's operations and its role in the maritime industry. The Ambassador was welcomed by Mr Moran Mano, Vice President of Mano Maritime, who provided her with an overview of the company's history, operations, and its contribution to the development of the maritime industry in the region.
Mano Maritime, a leading cruise and shipping company, can trace its roots in Israel from before the country's independence in 1948 and has since expanded its operations to include cruise ships, cargo vessels, and port services. The company operates in the Mediterranean, the Black Sea, and the Red Sea. During her visit, the Ambassador was given a tour of the company's offices and facilities, including company's flagship cruise liner the Crown Iris at the port of Haifa. The Ambassador also met with key personnel from different departments, including sales and operations.
The visit by the Maltese Ambassador to Mano Maritime underscores the importance of promoting trade and investment between Malta and Israel and highlights the potential for further collaboration between the two countries in the maritime industry. As a testimony of the growing cooperation, The Crown Iris is also expected to make several stops in Valletta during 2023.

Hyperbolic plane has a beautiful triangulation by congruent hyperbolic triangles where all the vertices of the triangulation have degree 7, this is of course not possible in the euclidean plane, even more, I think it is not possible to triangulate the euclidean plane with triangles that are $C$-bilipschitz with a unit triangulation for some constant $C$, because that would imply there is a bilipschitz map from $\mathbb{H^2}$ to the euclidean $\mathbb{R^2}$ and this is not possible, is that correct?
So my question is: is it possible to triangulate the euclidean plane with any kind of euclidean triangles such that at every vertex has degree 7. I've been trying to do it by hand but always a lot of little triangles start appearing and I'm not certain if I can continue triangulating in such a way that the whole plane is covered.

Take a conformal map of the hyperbolic plane to the disc and triangulate it in a way reminiscent of an M.C. Escher painting. Map the vertices from the disc to the plane with some stupid map - the inverse of $(x,y) \to (x/\sqrt{1+x^2+y^2},y/\sqrt{1+x^2+y^2)$, say. Then draw a straight line between every pair of vertices that had a straight line drawn between them before. If none of the lines cross and none of the triangles start overlapping, you're good, but I'm not sure how to figure out whether this happens. – Will Sawin Aug 8 '12 at 18:11

Unless I am missing something: start with the image of a degree-seven triangulation of the hyperbolic plane (coming from the (2, 3, 7) triangle group -- that is the triangulation both you and _USER_ seem to be alluding to) in the Beltrami-Klein model (this will be a triangulation of the disk with Euclidean straight edges). Then lift the vertices of which are distance $r$ from the origin by some monotoically increasing convex function of $r,$ such that $f(1) < \infty, f(0) = 0$ This will move your triangulation to a straight-line triangulation of a convex "cup." Now centrally project this from the point $(0, 0, f(1)).$ The image will be a combinatorially equivalent triangulation of the plane.

_USER_: I think, the easier way to describe what you are doing is to realize (2,3,7)-triangulation of hyperbolic plane on the hyperboloid $x^2+y^2-z^2=-1, z>0$, then straighten it replacing hyperbolic geodesic segments with Euclidean ones. Now, project the result orthogonally to the xy-plane and you are done. – Misha Aug 8 '12 at 20:16
Thanks Igor and Misha for your quick and clear answers. – shurtados Aug 8 '12 at 20:42
_USER_: yes, of course you are right. What I am describing is slightly more general, but also I was conjecturing that the OP might have been less familiar with the hyperboloid model... – Igor Rivin Aug 9 '12 at 13:19
I am not sure what you are asking in your first question (what is a "unit triangulation"?) but one can prove the following:
There is no geodesic triangulation of the plane with all vertices of degree >6 and such that the following conditions holds:
b) the angles of triangles are bounded from below.
Condition b) means that each triangle is bi-Lipshitz to an equilateral triangle, so this is probably what you ask. And the reason you mention is valid.
Examples of geodesic triangulation with vertices of degree 7 are given in the previous answer, and it follows from, b) that some triangles in these examples are very thin.
Edited later. My first answer also had condition
a) all triangles are bounded.
I claimed that b) can be replaced with a).
This condition CANNOT be used to replace b). Here is an example of a geodesic trianglation of the plane with all vertices of arbitrarily high degree, and bounded triangles.
Begin with an equilateral triange inscribed in the unit circle. From each vertex draw segments from the unit circle to the concentric circle of radius 2, so that the degree of each vertex on the unit circle becomes large. Add some chords of the circle of radius 2, connecting the endpoints of these segmnts. Draw additional segments to make this a triangulation of some polygon inscribed in the circle of radius 2. All inner vertices of this triangulation have large degree.
Now repeat this construction. We obtain a sequence of larger and larger polygons $P_n$ each inscribed in a circle of radius $n$, and each polygon is triangulated so that the degrees of inner vertices is large. Continuing this indefinitely, we obtain a triangulation of the plane.

How to design packaging tape (video tutorial)
Publicado por Hayden Aube
Designer, Hayden Aube, shows off his favorite techniques for creating a seamless packaging tape design in Adobe Illustrator.
When ordering from Sticker Mule, our artists will work with you to transform your design into a seamless pattern, but if you'd like to do it yourself, follow along.
Step 1: Create your document
Create a new document. The size of your artboard will determine the size of your pattern.
Step 2: Layout your tape
Using the Rectangle tool (M), create a rectangle that matches the size of your artboard.
Remove the stroke, and give it a fill with you desired background color.
Position the rectangle directly at the center of your artboard and lock it in place.
Step 3: Add design elements
Place any design elements you want to include in your pattern over the existing background.
Be sure to have some of the design overlapping the edge of the artboard. This will help to create the seamless pattern.
Step 4: Reposition overlapping elements
Duplicate each object that is overlapping the edge of the artboard (Copy, then Paste in Front).
Next, move each object to the opposite side of the artboard. Use Object > Transform > Move to move it exactly the same width or height of your artboard.
Step 5: Make your clipping mask
Using the Rectangle tool (M), create another rectangle that matches the size of your artboard, then align it to the center of your artboard.
With everything selected, right click, and select Make clipping mask.
Step 6 (optional): Add to Swatches
With everything selected (including the background), drag the artwork to your Swatches panel. This will create a pattern that you could then apply to any shape.
Once you have a pattern you're happy with, you can upload it to Sticker Mule for printing.
As with all of our orders, you'll receive a proof in 4 hours and our custom packaging tape ships in 4 days or less with free shipping. Samples of custom packaging tape featuring your design are just $4.

text: In possibly the most bizarre exception in English, the past tense of the verb hang is hung, except when speaking about the method of killing someone--then it's hanged. This, however, is relatively uncommonly used correctly, which, when combined with the slang meaning of the word, a shorter version of well-hung, results in tremendous humor potential. This potential has been most effectively realized, to my knowledge, in Mel Brooks' Blazing Saddles. The main character, Bart, is greeted by his friend Charlie with, "They said you was hung!" "And they was right," is Bart's reply.

Youngsters at Ferring Primary in Sea Lane have been busy growing tropical fruit tree species, identical to those grown as part of a special project in Malawi, which grows a tree for every ton of aluminium drinks cans recycled in the UK.
The children held a group fruit-tasting session to discover the flavour of fruits grown in Malawi and then used the seeds to plant their own trees, including avocado and mango.
A year on, the children's trees are thriving and they have collected an excellent 40 kilos of clean aluminium foil so far which will be counted towards growing trees in Malawi.
Zo Walker, a teaching assistant, said: "The whole school community is contributing to our foil collection and the pupils have enjoyed watching the plants developing in the classroom.
"Money from the recycling of the foil is passed to the Guide Dogs for the Blind."

Why Did Jesus Say He Came to Bring a Sword?
by Greg Boyd, originally posted at his website ReKnew.
Some, both modern scholars along with church leaders since the fourth century, have used this passage as evidence to argue that Jesus is not altogether non-violent.
When we place Matthew 10:34 in its broader context, it becomes clear that Jesus' teaching not only does not condone violence on the part of his disciples, it actually rules out all violence. As Jesus is preparing his disciples to proclaim the Good News of the arrival of the kingdom of God throughout the region, he warns them that he is sending them out "like sheep among wolves" (Mt 10:16, cf. vv. 5-15).

Visualizing Language Use in Team Conversations: Designing Through Theory, Experiments, and Iterations
One way to potentially help people develop effective teamwork skills is to visualize elements of their language use during team conversations. There are several challenges in designing such visualizations, such as how to balance attention between the conversation and the visualization and how much guidance to offer about appropriate behaviors. We discuss the design space around these questions in the context of GroupMeter, a chatroom augmented with visualizations of language use. We generate and critique potential answers to these questions using prior theoretical and empirical work, then describe how the interface evolved and how our answers changed over a series of prototypes we deployed in experimental studies. We conclude with the lessons from our experience that could be used by designers of collaboration-enhancing systems.


Lake Wind Advisory:
Lake Wind Advisories are issued when sustained winds of 25 knots or greater are expected for several hours during the first 12 hours of the forecast. Typically wind forecasts are expressed in ranges. Thus for example a wind forecast of 15 to 25 knots, or 20 to 30 knots would both constitute advisory level conditions. Winds of this magnitude typically create choppy to rough water in exposed areas, leading to potentially hazardous conditions for those operating small craft.


Flickerstrings is a new experimental work created by the developer of FIG and Jump on Mushrooms: The Game. In it, players are required to draw an object to use as a playable character, starting from the brown box and ending when the maximum line length is reached. Once drawn, the shape can be moved around using the cursor keys. This shape turns into an immovable platform when the player attempts to draw another shape from the brown box.
The length of each string is limited, but you can cancel any mistakes by right clicking before the shape is drawn. You can also press the space key to restart a level at any time.
There are a total of twelve stages included in this version.

Application Express and parsing of SQL
Recently, I worked with Oracle Support who was helping a customer who had a variety of questions about Oracle Application Express. One of the questions was:
"Please provide a detailed explanation of how apex interacts with database security. It appears that apex is manipulating queries prior to presenting them tot he database to be run either by wrapping them in a pl/sql block that prevents role based security from working or doing a pre-security check that doesn't check role level security prior to issuing a query, or some other even that bypasses role based security. "
Since there really isn't any great explanation of this anywhere, I'd like to provide a brief but lucid explanation about how parsing of SQL works in Oracle Application Express.
 - The Oracle database ships with a supplied PL/SQL package named DBMS_SQL, to perform the execution of dynamic SQL.
 - The Oracle database also ships with a supplied but undocumented PL/SQL package named SYS.DBMS_SYS_SQL. This package enables the execution of dynamic SQL but it also enables the parsing of a statement as a specific database user and with the privileges of this specific database user. This PL/SQL package is highly privileged, obviously. The EXECUTE privilege on this package is not granted to database user, by default. It should almost never be granted to any database user, ever. When asked to grant execution on this package to someone, a smart DBA will always say "no."
 - Until Database version 10.2.0.3, both DBMS_SQL and DBMS_SYS_SQL would not observe roles when parsing SQL. This was consistent with database object access in PL/SQL itself (database roles are not observed in PL/SQL, in case you didn't know).
 - In Database 10.2.0.3 and later (and XE), SYS.DBMS_SYS_SQL was changed to support a flag which enabled the observation of database roles when parsing SQL.
 - In Application Express 2.1 and later, support was added to Oracle Application Express SQL Workshop on DB versions 10.2.0.3 and later to observe database roles, to be consistent with SQL*Plus. However, the execution of SQL in an Application Express application still does not observe roles when parsing user SQL. This remains true for the recently released Application Express 4.0.
So this explains a few things:
 1. If you've ever wondered how Application Express can parse SQL as a specific database user and with the privileges of this database user but without ever connecting as that database user, this is the answer - DBMS_SYS_SQL.
 2. When a new database user/schema is provisioned through Application Express, the discrete system privileges are granted to this new database user and not through any database role.
 3. When you look the underlying database view V$SESSION, it will show that the database sessions associated with Application Express applications are connected as the minimally privileged database user APEX_PUBLIC_USER (or ANONYMOUS, if you're using the embedded PL/SQL gateway). But within that session, the underlying Application Express engine is being invoked and, after determining who the SQL can be parsed as for that specific page view, the SQL is being parsed as a different database user.
 4. This also explains why, in some database versions, it will appear that roles are enabled when you issue DML statements from SQL Commands in SQL Workshop, but in the development of your application and in the execution of your application, it will appear that database roles are not enabled and that direct object privileges are required.

But, you can fairly easily develop VPD policies that do use the roles, or roles that you've setup with your Apex application that are observed. So while this doesn't do too much for system privileges it does let you use roles to secure the data, which the original person may have interested in as well. Maybe I am off base on what they were shooting for.

LiveCode LessonsLiveCode Data Grid Using The Built-In Field EditorHow Do I Save Changes The User Makes In An Editor Field To An External Data Source?
How Do I Save Changes The User Makes In An Editor Field To An External Data Source?
When Calling EditFieldText with 3 Parameters (Simpler)
When calling EditFieldText with all three parameters (which is what a data grid column does by default) the data grid will automatically save the text that the user enters in the dgData array. That means that all you need to do is save the text of the editor field to your external data source in the CloseFieldEditor message. Note that if you save anything other than the text of pFieldEditor then your data source will not match the dgData value.
Here is an example script that goes in the Data Grid group script.

## An example that saves
on CloseFieldEditor pFieldEditor
put the dgColumn of the target into theColumnBeingEdited
put the text of pFieldEditor into theNewText
## Save data to database using command I defined
put "Person" into theTable
## Get the unique id of the row in the database we want to edit
put GetDataOfIndex(the dgIndex of the target, "id") into theRowID
SaveDataToDatabase theTable, theRowID, theColumnBeingEdited, theNewText
end CloseFieldEditor
When Calling EditFieldText with 1 Parameter (More Flexible)
If you are working with data grid forms or decide to override the default behavior for data grid columns then you will make the call to EditFieldText yourself. For complete control over what gets saved you only pass in 1 parameter to EditFieldText. By passing in 1 parameter you are responsible for saving any changes to dgData.
Assume you made the following call in a data grid form:
EditFieldText the long id of field "Name" of me
CloseFieldEditor would still be sent when the user changes the contents of the field but would need to contain code for saving the changes to the dgData array.
Here is an example script that goes in the Data Grid group script.
## CloseFieldEditor placed in data grid script
on CloseFieldEditor pFieldEditor
put the dgColumn of the target into theColumnBeingEdited
## Store UTF8 text
put unidecode(the unicodetext of pFieldEditor, "UTF8") into theNewText
## Save data to database using command I defined
put "Person" into theTable
## Get the unique id of the row in the database we want to edit
put GetDataOfIndex(the dgIndex of the target, "id") into theRowID
SaveDataToDatabase theTable, theRowID, theColumnBeingEdited, theNewText
## Update dgData.
## Setting dgDataOfIndex will refresh the data grid display as well as update dgData
put the dgDataOfIndex[ the dgIndex of the target] of me into theDataA
put theNewText into theDataA[theColumnBeingEdited]
set the dgDataOfIndex[the dgIndex of the target] of me to theDataA
end CloseFieldEditor

Point of clarification:
in the examples, your step that actually does the DB save is told the table, the column and the new value... but not the row ID? Would this not update EVERY row, putting the new value in the selected column for ALL rows? Since I can't imagine that was the intent here, how indeed are you telling the DB to update just the one row you wanted to change?
Trevor DeVore
@jkrische: yes, the id was unintentionally left out in the example. I've updated the example so that it includes code that gets the unique row id to use when updating the database.
Sean Cole
What is the SaveDataToDatabase command and what does it do?
Trevor DeVore
@Sean - The command isn't defined in the example script. It is an example of a command you would call to save the changes to your database. This is something you would have to implement yourself as it would be specific to your project.
Sean Cole
Ah, ok. It was 'how to save to an external source' that I was trying to understand (which is probably the bit in that command). I figured this was the best place to come. I'm trying to output a data grid to a data file directly (not as text file in csv but as something I can reload quickly as is as persistent storage as the custom properties are not storing them as I expected and return to they're original values at stack load.
Trevor DeVore
A sqlite database is one option. There is a lesson on using one at _URL_

Due to the progression of aging in Japan, pharmacists need to participate in home medical care. To enable pharmacists with no previous experience to participate in home medical care of patients with various diseases in the home environment, it is necessary to adopt an approach of training them in advance. It is thought useful for such clinical training to include patient case studies, which may facilitate the training of pharmacists for home medical care through simulated experience. "The working group to create home clinical cases for education" was launched by a group of university faculty, who have educational knowledge, and trained pharmacists who work with the patients at home. The home care cases were compiled by the university faculty members and the home care practice pharmacists. Working pharmacists and students at pharmaceutical college studied the same case studies of home medical care, and their self-evaluations were compared. They showed that the students rated themselves higher than the pharmacists. One of the reasons was the systematic education of the case studies. The clinical case studies are a good educational tool to promote home care medicine in pharmacies and university pharmaceutical colleges.

Scots don't eat well, but that doesn't mean that they don't care about their health. They have some of the best food in the world. Salmon, venison, and eel are plentiful, as are the seas. But while most people in Scotland have nothing more than boiled vegetables, many Scots have a diet full of lard, sugar, salt, and fried potatoes.
One of the reasons why Scottish food has a bad reputation in the United States is the poor quality of its food. Most Scots are not aware of the number of nutrients and vitamins that they should consume, so they often eat fast foods. This has led to a huge epidemic of obesity and malnutrition. Fortunately, the Scottish are beginning to take action. The government has published a new report that highlights the importance of healthy eating.
While it may seem odd to associate the Scottish word "haggis" with the word "haggis," it has a good reputation, particularly in America. For example, haggis is a staple in American restaurants. But while it has a bad reputation, Scottish cuisine is changing – and the country is proving it to us. Those who are skeptical about the culinary tradition will have to make their own discoveries to get a taste of what's in a Scottish meal.
The poor quality of Scottish food can be traced back to the feudal system. During the first millennium, Scottish food was heavily restricted. The great men of the realm ate venison, boar, various fowl, and songbirds. This cheap sugar also helped fuel a cottage industry, where Sweetie Wives bought bulk sugar, boiled it into homemade sweets, and sold them at local markets. It is possible that the cold climate is partly responsible for this sugar-hungry culture, as it has a pronounced effect on the body.
Even though the Scottish have a notoriously poor reputation when it comes to food, things are changing. The Scottish national dish haggis has earned iconic status as the symbol of Scotland. But it is not just haggis that is bad. There are plenty of other tasty foods in Scotland that are not so bad. For instance, the popular black pudding and savory haggis are both good for you. Moreover, the Scottish are proud of their culture, and their culture.
However, the overall quality of Scottish food is still good despite its reputation. The high calorific value of the Scottish diet has made the nation's population sick, so it is vital that we eat healthily. But Scottish people – no matter how much they scoff at their food – have little to celebrate. And yet, the food in Scotland is generally bad for our health. In addition, the English are more likely to eat more red meat and processed meat than the Scots, which is not a good thing.
The Scottish diet has been notorious for decades. The British have long blamed it on the British for eating Scots' greasy and unhealthy foods. It has been said that the Scottish are not fit for eating. Besides, their poor diet is detrimental to their health. They are not able to enjoy the food they love. They should avoid all types of Scottish food, especially the ones made in Scotland. Nevertheless, the English have a hard time understanding why Scottish food is so terrible.
The Scottish diet is notorious for being unhealthy. It is associated with smoking and a sedentary lifestyle and is linked to a high-fat diet. The Scottish are also at risk for cancer. In addition to its unhealthy qualities, the Scottish are known for being among the healthiest people in Europe. Its dietary habits are often influenced by a person's age, but if they're in good health, they can survive without smoking.
The Scottish diet is not healthy. Studies have found that the average Scottish diet is low in vegetables, fruits, and cereals. Most of the Scottish population eats foods rich in sugar, such as chocolate and fatty meat products. Furthermore, they don't exercise, which makes them more likely to develop diseases. So, it's no wonder why they're not eating well. The answer might surprise you! This is largely down to the lack of local businesses, but they don't make much money.


Question: Which Format Has The Largest File Size?

It's generally accepted that a message size of around 20MB is too large to send via email, and you'll find in lots of cases that mail servers will actually refuse to accept files that are this big.
Which JPEG format is best?
And while the graphics and the images with letters are usually better-looking in the . png file, with the regular photos, JPG is a better choice for the web because if the smaller size. If you decide to use PNGs only, they will slow your website which can lead to frustrated users.
Is a PNG file smaller than JPEG?
The full-size PNG has a file size of 402KB, but the full-sized, compressed JPEG is only 35.7KB. JPEG works better for this image, because JPEG compression was made for photographic images. The compression still works for simple-color images, but the loss of quality is far more noticeable.
What's bigger MB or GB or KB?
KB, MB, GB – A kilobyte (KB) is 1,024 bytes. A megabyte (MB) is 1,024 kilobytes. A gigabyte (GB) is 1,024 megabytes. A terabyte (TB) is 1,024 gigabytes.

Is 23 MB too big to email?
In general, when attaching files to an email, you can be pretty confident that up to 10 MB of attachments will be okay. Today, few email servers have smaller limits than this (though some old office set ups may have lower limits). Gmail and Yahoo Mail, by way of example, both allow you to attach up to 25 MB.
Which is higher MB or GB?
In binary base, one megabyte is equal to 1,048,576 bytes. … 1 Gigabyte is considered to be equal to 1000 megabytes in decimal and 1024 megabytes in binary system. As you can see, 1 Gigabyte is 1000 times bigger than a Megabyte. So, a GB is bigger than a MB.

Which format has the smallest file size?
JPGOn the web, JPG is the clear choice for photo images (smallest file, with image quality being less important than file size), and GIF is common for graphic images, but indexed color is not normally used for color photos (PNG can do either on the web).
Does cropping reduce file size word?
Instead, cropping means that you are simply telling Word how much of the original graphic you want displayed. If the graphic is embedded in the document, then cropping it is not a way to reduce file size because the full, complete graphic is still saved with the document.
What is better JPEG PNG or TIFF?
The PNG (Portable Network Graphics) format comes close to TIFF in quality and is ideal for complex images. Unlike JPEG, TIFF uses a lossless compression algorithm in order to preserve as much quality in the image. … The more detail you require in graphics, the better PNG is for the task.
Are GB bigger than KB?
There are (from largest to smallest): Gigabytes(GB), Megabytes(MB), Kilobytes(KB), Bytes and Bit. But that really doesn't tell you much other than a gigabyte is bigger than a kilobyte.
Is KB bigger than MB in file size?
1 KB (Kilobyte) is equal to 0.001 MB in decimal and 0._PHONE_ MB in binary. It also means that 1 megabyte is equal to 1000 kilobytes in decimal and 1024 kilobytes in binary. … 576 bytes in binary. So as you can see, a Megabyte is one thousand times bigger than a Kilobyte.
Which is better TIFF or JPEG?
TIFF files are larger, but will not lose any quality or clarity when edited and saved repeatedly. JPEGs, on the other hand, will lose a small amount of quality and clarity each time they are saved.

HISTORY OF VINTAGE HANDBAG The Birth of the Bag 1900- Dorothy bag
HISTORY OF VINTAGE HANDBAG
The Birth of the Bag 1900-
We introduced Edwardian Lady of 1900 yesterday, here we
Describe Dorothy bag:
Dorothy bag was used for more intimate occasions, such as at home a circle of dress fabric gathered together by a drawstring at the top to create a frilled opening, they were pretty concoctions of sequined net with a lace insertion, decorated with beadwork or embroidered flowers.
The bags were related in type and construction to the nineteenth century needlework bag, and named after Dorothy, the eponymous heroine of A J Munby's play of the 1880s.
Fine sewing was a customary activity of the house bound housewife, and this often included the making of a needlework bag, finished off with a pair of store bought handles.
However, the more complex and sophisticated needlework bags were manufactured in Austria, well know for the production of fine needlepoint and petit poit evening bags.
Professional embroiderers would transfer images from classical paintings and prints onto a gauze backing by the means of a cardboard grid.
More than 500 shades of silk thread and several thousand stitches per inch went into the making of the bag, which would then be attached to a jeweled or enameled frame.
We will introduce Mesh Bag to-morrow.

What can you make with a sheet of paper? You could: fold it into a paper airplane, an origami swan, or even a telescope. But what if, with a few cuts, you could transform it into something that's as useful as it is beautiful? Enter the paper cone nightlight, a lamp you can make with paper and just a few small parts.
The components are simple: a few sheets of white paper, some scissors and tape, and a few electrical components from Adafruit, an open-source hardware and electronics company. But the results will be anything but.
What You'll Need
- 3.7 volt Lithium Ion Battery ($5.95 at Adafruit)
- Micro Lipo with MicroUSB Jack USB Li-Ion Charger ($6.95 at Adafruit)
- One JST 2-Pin Cable ($.75 at Adafruit)
- Diffused White10mm LED light ($.50 at Sparkfun; $11.95 for a 25-pack at Adafruit)
- Letter-sized white office copy paper (Ideal: 20lb with a brightness of at least 92)
- Scissors and/or an X-Acto Knife
- Transparent Tape/Scotch Magic or Similar. (Optional)
How to Build a Paper Cone Nightlight
Step 1: Cut out and assemble your paper cones
A: On sheets of white office paper, draw and cut out circles of different sizes. Make your largest circle as big as you can on the paper and your smallest circles about half that size (two circles on a single sheet of paper). If you can fit three circles on a single sheet, your circles are too small. Each circle with make one cone. You can make your nightlight with just one cone or by stacking as many as you like. Just for fun, let's start with four.
B: Once you've cut out the circles, remove a pizza slice from each one. Your slices may be as large or as small as you like. The size of each slice will affect the height of the cone, once you roll the paper into a cone shape.
C: Make your cones by connecting the two straight edges to each other. Align one straight edge with the other and place a piece of scotch tape across the joint. In order to stack your cones, snip off the tip of the cone. You can do this by removing a smaller circle around the center of the larger circle, creating what's called a flat-top cone.
Step 2: Wire Your LED
A: Strip 3/4" of the red and black coating from the ends of the JST cable wires. If you don't have a wire stripper, you can use a knife to cut through the coating. Pull the coating off by squeezing it between your fingernails.
B: Attach the red lead of the JST Cable to the "BAT" terminal on the Micro Lipo board. Attach the black lead to the "GND" terminal. If you have a soldering iron, solder this connection. If you don't, wrap the wires around the terminals making sure the wires do not touch each other.
C: Connect the battery to the Micro Lipo board and plug in the LED. Plug the positive lead (the longer lead) into the red wire socket and the negative lead into the black wire socket. The LED should immediately light up. To turn off the light, unplug the LED. (To charge the battery, connect a micro USB cord from your computer to the USB port on the Micro Lip board.)
Step 3: Assemble Your Light
A: Turn on your LED and place it on a table.
B: Cover the LED with one of your paper cones. Note how the light changes the look of the cone. If you put the LED under a flat top cone (a cone with a hole at the top) light will escape through this hole.
C: Try stacking different sized cones on top of one another by altering the direction each cone is pointing.
D: Once you have a tower you like, try repositioning the LED inside the tower.
When your nightlight is complete, it will look something like these — or whichever configuration of cones you can dream up:
Downloadable Instructions + Templates
To make the assembly process as simple and straightforward as possible, we've put together these instructions and templates to get you started. In this downloadable PDF, we've included a few pages with starter circles, which have built in tabs and slots. If you have access to an X-Acto knife (or a laser cutter), you can skip the tape and use the tabs/slots instead.

In this study, molecular properties of wheat starch from three different types of breads were analyzed using asymmetric flow field-flow (AF4) connected to multi-angle light scattering (MALS) and differential refractive index (dRI) detectors. This analysis allowed the determination of molecular properties, i.e. molar mass (M), root-mean-square radius (rrms), apparent density (ρapp) and conformation. Complementary analyses, such as resistant starch and amylose content, were also performed. The results show that wheat starch extracted from breads can have different properties reflected in changes in M, rrms and ρapp. In addition, the results suggest that some of the changes in molecular properties may be related to the presence of resistant starch.

Brumovská, Tereza J., & Brady, Bernadine. (2021). Initial Motivation of Mentors in Formal Youth Mentoring Relationships. Child Care in Practice, doi:10.1080/_PHONE_.2021._PHONE_
The paper presents results of a phenomenological longitudinal qualitative study undertaken with mentors associated with the Big Brothers Big Sisters programme in the Czech Republic. Ten mentors were interviewed during the first month and after 5 and 10 months of their mentoring involvement employing phenomenological in-depth semi-structured interviews. Interpretive Phenomenological Analysis (IPA) was subsequently applied using QSR NVivo software for data analysis. This paper reports the findings of an IPA analysis of one of the central theme of mentors' experience, common to all interviewed mentors: initial motivation to volunteer in formal youth mentoring relationships (FYMRs). The findings of the IPA analysis are discussed using the framework of self-determination theory (SDT) with its continuum of autonomous and controlling motivations. As a result, we argue that the initial motivations of mentors can be assessed according to the level of autonomy in mentors' motivation, in other words, congruence of their motivations with the authentic self. We argue that the level of congruence of mentors' motivation with the authentic self can be considered as the quality feature of the mentors' motivation. We conclude that, in theory, this feature has an impact on the subsequent dynamics and perceived satisfaction of formal youth mentoring relationships. We recommend that the mentors' motivation, and specifically, the level of autonomy in mentors' motivation to volunteer with socially disadvantaged children be assessed in mentoring programmes as a qualitative feature in mentorś training and recruitment.

Romantic relationship satisfaction relates to better overall health, and identifying factors that affect relationship satisfaction could lead to better understanding of romantic relationships. This study examined the correlation between benevolent sexism, a subtle form of sexism resembling chivalry and relationship satisfaction; gender, age, ethnicity, religious beliefs, education, and length of time were also considered as moderators. The ambivalent sexism theory, which posits that sexism is ambivalent and ranges from hostile to benevolent sexism was the theoretical framework guiding this study. Previous research indicated benevolent sexism may predict relationship satisfaction. However, there remained an important gap in the literature; the demographic variables above had not been considered as moderators in those analyses. Thus, the purpose of this non-experimental study using data collected from a U.S. sample of adults who had been in romantic relationships for at least 1 year was to determine if such links existed. Correlation and regression analyses revealed that benevolent sexism, measured by the Ambivalent Sexism Inventory did not predict relationship satisfaction, measured by the Relationship Assessment Scale, and none of the demographic variables served as moderators. Results were trending toward significance though, suggesting that benevolent sexism might influence women's relationship satisfaction. Further research using longitudinal, mixed-method studies of dyads is recommended to gain a clearer understanding of this phenomenon. Findings would make important contributions to existing literature and enhance social change by providing professionals and individuals with awareness of how benevolent sexist attitudes may affect relationship satisfaction.

How to replace food stamps
COLUMBUS - The Sept. 14 wind storm that left more than 2 million Ohioans facing longterm power outages is more than an inconvenience to food stamp recipients.
According to the Ohio Department of Job and Family Services (ODJFS), food purchased with food stamps can be replaced in certain circumstances, including if it spoils because of a power outage lasting longer than four hours.
To replace spoiled food purchased with food stamps, individuals must visit their county department of job and family services (CDJFS) and complete and submit a "Statement Requesting Replacement of Food Stamp Benefits" form. This form must be submitted within 10 days of the event that caused the food to spoil (in this case, Sept. 14) or, if the person was away from home, 10 days from when the food spoilage was discovered. Individuals can request an amount equal to the amount of food lost, but not exceeding the food stamp allotment for the month in which the disaster occurred.


How to Find out What Is Taking up Space on an iPhone (4 Steps)
By C. Taylor
The Apple iPhone has a finite amount of memory that must house photos, videos, music, apps and data. Without memory card support, you can't simply change cards to create storage space. Therefore, you'll eventually need to clean the iPhone to create space for new apps or files. The first step in creating space is knowing what is taking up the most space on the device.
Step 1
Tap "Settings" from the iPhone's home screen.
Step 2
Tap "General" and then "Usage."
Step 3
Look in the "Storage" section to see which apps and file types use the most space. The list is in descending order by the amount of memory used, so the top-most apps use the most space. If you need to see more than the top 10 memory-consumers, tap "Show All Apps."
Tap any listed item to see further details of its memory usage.

I'm wondering if the following can be true: Let Y be a second countable space and $\pi_2:Y \times \mathbb{R}\rightarrow\mathbb{R}$ ($\mathbb{R}$ with its usual topology and $\pi_2$ the projection onto the second factor) be a closed map: do these assumptions imply that Y is compact? (There is no assumption $T_0$, $T_1$ or $T_2$ on $Y$.)
thank you in advance.

Let $(y_n)$ be a sequence in $Y$. Let $A$ be the subset of $Y \times \mathbf{R}$ of all points $(y_n, \frac{1}{n})$ for $n \in \mathbf{N}$, and let $B$ be its closure. Then $\pi_2[B]$ is closed in $\mathbf{R}$, and contains all points $\frac{1}{n}$, so it contains $0$. So for some $y \in Y$, $(y,0) \in B$. Using the countable base we can extract a subsequence of the $(y_n)$ that converges to $Y$ (as $Y$ is first countable in particular). We do then need that $y$ is in the closure of all subsequences of $(y_n)$ as well, which follows in a similar way, otherwise we cannot get (without separation axioms) a convergent subsequence from first countability alone. But this works.
So $Y$ is sequentially compact, which implies that $Y$ is countably compact (in the covering sense; no separation axioms needed) and as $Y$ is also Lindelöf, being second countable, $Y$ is compact.

I assume that by compact, you mean quasi-compact (i.e. not necessarily Hausdorff but with the finite sucover property), otherwise any $Y$ with the coarsest topology would be a counterexample.
Then it seems that your notion is equivalent to pseudocompactness, namely that any continous $f:Y\to\mathbb{R}$ has compact image. I checked that quickly, so I may be wrong.
EDIT : indeed I am, see below. The property is slightly stronger than that.
(I haven't found a reference in MR, although I would bet it is an exercise in Bourbaki).
The idea is first to observe that the property remains the same if you substitute $\mathbb{R}$ with $[0,1]\simeq[-\infty,\infty]$, basically because any one is included in the other (up to homeo).
Then since the graph of a continuous $f:Y\to\mathbb{R}$ is closed, $f(Y)$ must be closed in $\mathbb{R}$ and also $[-\infty,\infty]$, hence bounded. Similarly, any lower/upper semi-continuous $f$ is lower/upper bounded and attains its inf/sup, since $f$ is lsc iff its "epigraph" $\{(y,t):f(y)\leq t\}$ is closed.
For the converse, if $F$ is closed in $Y\times[0,1]$, but not its projection $F_2$, one may assume that $0$ isn't in $F_2$ but is in its closure. Then the function $y\mapsto \inf t : (y,t)\in F $ is lower semi-continuous and doesn't attain its infimum $0$.
EDIT: pseudocompactness doen't imply that lsc functions attain their infimum in general (not completely regular) spaces : there is no way to construct a continuous function from an lsc one if there are "not enough" continuous functions. Your property is indeed stronger than pseudocompactness, as the particular point topology on $\mathbb N$ shows. This space is homeomorphic to $\mathrm{Spec}(\mathbb{Z})$ with Zariski topology : a discrete countable subspace (primes) plus a dense "generic point" (0). Any continuous function is constant (hence pseudocompactness), but a function $f$ is lsc iff $f\leq f(0)$!! (I checked that twice, it's so shocking!)
So your property is equivalent to "lsc real-valued functions attain their lower bound", which may have a name, I don't know. Maybe "strongly pseudocompact"?
By the way, pseudocompact doesn't imply (quasi-)compact, even for "nice" (completely regular) spaces, as is seen with the long line or simply the first uncountable ordinal $\omega_1$ (with order topology). There are also non-Hausdorff examples, see wikipedia article.

I thought about the latter too, as all countably compact space satisfy the fact that the projection onto R is closed (we can replace R by any sequential space even). But of course I realized we cannot have a second countable (note that condition! the OP works in second countable spaces) counterexample, as a second countable space is Lindelöf, and a Lindelöf and countably compact is compact... So the standard examples do not work. I also don't see why we can replace R by [0,1]: closedness is not preserved by embedding... So please elaborate on that? – Henno Brandsma Jul 13 '10 at 16:38
This is the following lemma : If projection $Y\times Z_1\to Z_1$ is closed and $Z_2$ is a subspace of $Z_1$, then $Y\times Z_2\to Z_2$ is also closed. Proof: take $F$ closed in $Y\times Z_2$ the projection $G$ of its closure $\overline{F}$ in $Y\times Z_1$ is closed in $Z_1$, so $G\cap Z_2$ is closed in $Z_2$. But since $\overline{F}\cap(Y\times Z_2)=F$ (opens of subspace are traces of opens of ambient space), this is the projection of $F$. – BS. Jul 13 '10 at 18:31
And I overlooked the "second countable" hypothesis, which ruins my counterexamples. – BS. Jul 15 '10 at 9:50

text: Free-space optical (FSO) communications will play an important role in the backhaul of future generation of wireless networks in order to support high data rates. Because of narrow beamwidth inherent to an optical signal, acquisition and tracking form an important component of any FSO communication system. In this study, we have analyzed the optimization of received power allocation between tracking and data channels in an FSO receiver. In this regard, we have carried out a detailed analysis of the error statistics of the centroid estimator that is used for tracking the beam with the help of an array. The objective function that is optimized (minimized) are the probability of error and the probability of outage, and the optimization of power allocation is carried out as a function of parameters such as noise power, pointing error variance, pointing error correlation coefficient, and the threshold of outage. We have analyzed the optimization concerning the lognormal and exponentiated Weibull fading scenarios as well. We learn that the optimal power allocation is a function of the received signal-to-noise ratio: a lower signal-to-noise ratio dictates that a higher fraction of received power should be diverted to the tracking channel and vice versa.

I have created an Java web application and deployed it on AWS Elastic Beanstalk. It;s working fine with its database.
Now, in my project users have the option to upload documents, pdfs and images. This is creating problems. In the local system I am using./ as the path for saving uploaded documents but on Amazon I don't know where to store these uploaded documents and how to assign a path.
So far I've done the following, which is all working okay.
 1. Uploaded a project on AWS Elastic Beanstalk.
 2. Created a database using AWS RDS.
 3. Both application and database are communicating with each other.

Is there a special reason for storing files in RDS?
for storing files I suggest you use S3 instead of RDS. Use the amazon SDK to do it, see,%20java.lang.String,,
Of course, your file-saving code should be pluggable, with at least two implementations. One implementation saving the file to the local disk and another for storing it in S3. your startup code should wire the correct implementation.

yes once you store it in (AWS) S3 bucket, get the credential details of it and create a credentials file
Much easier! :)

Relevance to Underserved Issue
The Health and Rehabilitative Services (HRSA) professional shortage area guidelines (HPSA) provide the criteria needed to determine locations that are underserved.
Summary of Key Information
- Purpose of the Guidelines
To provide criteria for identifying areas that have a deficit of mental health providers.
- Program Authority
The Public Health Service Act section 332 amended by public law 101-597 requires the Secretary of Health of HHS to establish, by regulation, criteria for the designation of HPSAs. Program RequirementsThe program requires that the core mental health providers who may offer mental health services consist of psychiatrists, clinical psychologists, clinical social workers, psychiatric nurse specialists and marriage and family therapists.
- Identified Need for Providers
HRSA has defined three types of shortage designations consisting of
- Geographic area
- Population based
- Facility based
Criteria necessary to be designated as a mental health shortage area under these categories:
A. Geographic Area Based Manpower Shortage Designations
- The geographic area is a rational area for the delivery of mental health services.
- One of the following conditions exists in the area:
- The population ratio to core psychiatrists and/or non-physician mental health professionals is disproportionate using HRSA defined ratios as defined in the summary table below.
- The area has unusually high needs for mental health services (i.e., poverty, children, elderly, high amount of substance abuse and alcoholism) and the ratio of population to core mental health clinicians is disproportionate to meet this need.
Contiguous area considerations: Mental health professionals near the areas that are being identified as HPSAs will be considered extremely far away, over-utilized or unavailable to the HPSAs if they meet the following criteria: (1) it is more than 40 minutes from the main population center of the area being considered, (2) if the core mental health professionals in that area are overutilized and con not be expected to fill the void (3) there is a cultural, language or geographical barrier and/or because of residency restrictions.
B. Population Based Manpower Shortage Designations
- Population groups in specific service areas are deemed as shortage areas if access barriers prevent the population group from using mental health services.
- The ratio of the number of individuals per population group is disproportionate to the number of full-time equivalent (FTE) mental health professionals or FTE psychiatrists.
C. Facility Based Manpower Shortage Designations
Types of facilities that fall under this designation include: federal and state correctional institutions, state and county mental hospitals, community mental health centers and other public or nonprofit private facilities.
Facilities can be deemed manpower shortage areas based on HRSA defined criteria that take into account variables such as the ratio of mental health professional to the defined population, average length of stay, average daily inpatient census, etc.

The multi-million pound finish, known as army brown, replaces the desert sand colour which has been used by the Army since World War Two operations in North Africa.
Specialists at the Leicester-based AkzoNobel chemical company obtained samples of rock and soil plus high-resolution imagery from Helmand in Afghanistan for their research.
The finish was developed jointly at the Government's Defence Science and Technology laboratory using expertise from AkzoNobel's Dulux and Sikkens paint brands.
The new coating includes a "paint and peel" version so that vehicles rushed to a conflict can be spray-painted and then, when they return to the UK, the coating can be peeled off.
"The secret paint scheme was seen for the first time at the MoD's Defence Vehicle Dynamics show in Northampton."
But the most advanced aspect of the sensitive project is that the coating will change when it absorbs toxic chemicals, alerting soldiers that they are under chemical attack.
The secret paint scheme was seen for the first time at the MoD's Defence Vehicle Dynamics show in Northampton.
Now scientists are working to try to develop the paint further so that as well as absorbing chemicals it can neutralise the toxins.
All Foxhound, Husky and a wide range of armoured vehicles used in Helmand and other conflicts are to be painted ready for future operations.
A small number of Warrior armoured personnel carriers have already been painted in the new colour and deployed on operations in Afghanistan.

AGRESTA, Marisa Cury; BRANDAO, Maria Regina Ferreira and BARROS NETO, Turíbio Leite de. Physical and emotional causes and consequences of career termination in sports. Rev Bras Med Esporte [online]. 2008, vol.14, n.6, pp. 504-508. ISSN _PHONE_.
INTRODUCTION: Elite athletes will have to face sport career termination sooner or later, and this is a crucial and inevitable process that brings about changes in the occupational, financial, social and psychological spheres of their lives, which can be followed by emotional distress. OBJECTIVE: The present study had the aim to research how former Brazilian basketball and professional soccer players have experienced retirement in sports career as well as its causes and consequences. MATERIAL AND METHODS: 79 former elite male athletes (soccer and basketball players) with mean age of 51.75 ± 8.85 years old were assessed. They have been professional athletes for 18.22 ± 4.66 years and had their career termination at about 34.36 ± 4.42 years. A semi-structured interview frame was used and the data were analyzed according to the answers frequency of occurrence for each interview item. RESULTS: It was observed that for 75.9% of these athletes the retirement from sport was their own choice. Age (49.4%) and appearance of other interests (43.0%) were the most frequent reasons related to the retirement. However, they have experienced feelings of sadness (50.6%) and resignation (36.7%) and 43% of the former athletes have experienced worsening in their physical condition after career termination. CONCLUSION: We can conclude that the hereby-assessed athletes have experienced a long sports career, but their retirement caused feelings of sadness. On the other hand, old age itself is a limitation for the practice of elite sports, and its acknowledgement has led to resignation.
Keywords : retirement; sports [psychology]; soccer; basketball.

|dc.description.abstract||The nature of employment contracts has often been blamed to influence the flow of work and as the reason for poor operational performance in intergovernmental organizations across the world. Many studies have been done on fixed term employment contracts but very little have been researched on how these influence the flow of work in intergovernmental organisations. The study examined the influences of fixed-term employment contracts on the workflow of intergovernmental organisations using the SADC Plant Genetic Resources Centre, in Lusaka, Zambia as a case. It focused on how the flow of work at these organisations is affected when the contracts of those employees superintending long term projects expire. Data was gathered from respondents using questionnaires and analyzed using the Statistical Package for the Social Sciences (SPSS). It was found out that fixed term employment contracts, to a greater extent, negatively affected the workflow of intergovernmental organisations. It was shown that there was interruption of work at the expiration of employee contracts, some planned projects are not implemented, abandoned along the way and yielded unsatisfactory results. Intergovernmental organisations are therefore recommended to match their employment contracts with the length of their projects, renewing these until the employee reaches retirement age or even giving permanent positions to high performers. It is also recommended that further studies focus on the need for intergovernmental organisations to hire employees specifically for projects that have got a known life span and match this with the contracts of employment as well as understanding losses incurred in these types of institutions as a result of the expiry of employment contracts.

Science says that air pockets are what makes a fluffy pancake. So, your major goal is to first obtain these bubbles in the batter, and then, solidify them.
These bubbles are formed from the release of gas, which is the product of adding baking powder to the pancake batter. When activated, baking powder performs its role as a chemical leavening agent, by producing CO2 gas. It is this gas that subsequently forms the bubbles.
The activation of the baking powder occurs in two stages:
- While mixing the ingredients: when you mix your dry and liquid ingredients, chemicals in the baking powder react, causing an initial and slow release of gas.
- When heating the batter: when you pour the batter onto a hot pan, a second, bigger burst of gas occurs.
This is exactly when pancakes get that exquisite fluffiness they are treasured for. The greater the heat, the more powerful is the release of gas.
Tip: you can't make fluffy pancakes with gluten-free flour. Without the elastic property of the gluten, the air pockets won't form in the batter.
As mentioned above, the next important step to getting fluffy pancakes is the solidification of the bubbles. This is also obtained during the heating process.
As soon as the batter hits the hot pan, less time than it takes for the bubbles to pop, the liquid in the batter cooks and turns to steam, the proteins in the egg coagulate, and the CO2 bubbles solidify into a network of air pockets. This produces the airy interior that gives a pancake its fluffy texture.
Keep in mind that the pan has to be hot enough (375 F.) to cause quicker activation of the baking powder, and subsequently, large bubbles and fluffiness.
Here are a few other important tips that'll help you get fluffy pancakes:
- Sugar slows the development of the gluten making the pancake softer, less rubbery, and less elastic. Sugar also aids browning.
- Salt also slows the development of the gluten, but it also produces a firmer dough.
- Fat will shorten the strands of gluten, reducing its elasticity. Therefore, substituting cream for milk would lead to a denser, less fluffy pancake.
- Flip the pancakes as gently as possible to avoid bursting the bubbles and making your pancakes very flat.

 Appraiser = is the person who calculated a value the price or the rate, to a house or something.
 Appraiser = evaluador, valuador o tasador
 Appraisal = valorización, estimación, apreciación, tasación, evaluación
 In Spain I would say "tasador" and "tasación".
 We had a so big housing bubble, that everyone can understand these two words.

A voice signal sample is stored as one byte. Frequency range is 16 Hz to 20 Hz. What is the memory size required to store 4 minutes voice signal?
This question is related to Cisco Interview

its 9600 bytes. as the voice frequency irange is in between 16-20,so sampling frequency must be grater than 40hz,so number of samples in 4min=40*240=9600 samples hemce we need a memory of 9600 bytes to store the voice signal
 - Aug 22nd, 2005
Its just 1440 bytes. Bandpass sampling frequency is just 6Hz. so just 6*240 bytes.

since the signal is in the band 16-20 HZ. bandwidth is 4HZ and so 8HZ sampling rate enough..i.e 8 s/sec. 4min=240sec.
4min duration has 8*240 samples
and each sample has 8 bits,so min required memory is 8*8*240=1920 bytes

It's 1920Bytes. As the bandwidth (f2-f1) is 20-16=4Hz. The sampling frequency should be twice the bandwidth (2B). the sampling frequency is 8Hz= 8 samples= 8 cycles/second.
4 minutes=(4*60) =240 Seconds
1sample->1 Byte
1Second->8 Samples
240 Seconds->(240*8) = 1920 Samples

Two things i wish to point here.
1) They have said that they are representing each sample by 8 bits. which implies that the sampling frequency is quite high. and that for one cycle of the minimum freq we get 256 samples.
2) Regarding the criterion that the sampling frequency should be twice of the bandwidth. this is applicable only when we are dealing with base band signal. whereas here it is pass band (since 16 to 20 is significant in our case).
So the sampling frequency should be quite high considering the two facts.
 Was this answer useful? Yes
 - Jul 12th, 2007
Nyquist–Shannon sampling theorem states that perfect reconstruction of a signal is possible when the sampling frequency is greater than twice the maximum frequency of the signal being sampled...so imagine sampling a 16Hz signal with 8hz...there's gonna be a sample every 2 cycles!..it has to be 40
 Was this answer useful? Yes
 - Aug 17th, 2008
Voice sample = 8 bit
Smaple frequency = 1/20 s = 0.05s
for 4 minutes = 4*60(minto sec)/0.05 = 4800 sample
s0 total memory = 8 * 4800 = 38400 bits = 4800 Bytes = 4.69 KB
 Was this answer useful? Yes
 - Aug 28th, 2008
banwidth of signal=4Hz
according to niquist theorem sampling frequency>=2*bandwidth
so sampling freq=2*4Hz(8 samples /sec)
1 samples is stored as 1 byte
so 8*8 bits/sec
so for 4 mins bits are = (4*60)*(64)=15KB
so asn is 15 KB.

Voice signal is sampled at 8000 samples per second. (Human voice is in the range of 300Hz-3400Hz, and according to nyquist sampling rate we take it more than double the rate).
For a 4 min. voice signal, we have

What Road Salt Does to Your Car
what road salt does to cars
Yet there are some definite downsides to road salt when it comes to your car. Read on to learn exactly how road salt works—and what road salt does to your car.
How road salt works
Salt—a.k.a. sodium chloride in scientific terms—lowers the melting point of water. So while water normally freezes at 32 degrees Fahrenheit, water needs colder temperatures in order to freeze when it's exposed to salt. The more salt you add, the lower the temperature needed to freeze water is.
The water that results after salt is applied to ice is known as "brine." This water needs a temperature lower than 32 degrees Fahrenheit in order to freeze. If there's a lot of snow and ice on a road, the brine will seep into the bottom layers, breaking the bond between the ice and the road. The remaining snow and ice will then float along the top of the brine, making it easy for any passing traffic to break it up for good.
What road salt does to your car
Salt creates chemical reactions that can corrode your car. This is especially true if you have any exposed metal on your car.
So what's a motorist to do? Fortunately, there are some tried-and-true ways to help protect your car from road salt damage.
 - Have any scrapes, chips or rust spots repaired before the first snow falls.
 - Refrain from driving behind trucks spreading ice or brine.
 - Give an older car some extra TLC. The National Highway Traffic Safety Administration says that cars are especially susceptible to corrosion after being exposed to road salt for eight years or more.
 - When spring arrives, consider a thorough exterior detailing job. (Also consider taking other steps to help your car recover from winter.)
