I am currently reading the book Mathematics in physics by Michael Stone and Paul Goldbart. In chapter 11, page 421, the authors say that
"Except in pathological cases, the configuration space M of a mechanical system is a manifold."
Are the authors correct? What examples are there of these pathological cases? Are there any physically relevant cases where the configuration space in classical mechanics is not a manifold? And why does configuration space have to be a manifold - what about variables taking on discrete values?

 $\begingroup$ If the system has a configuration space of discrete values then anything which requires continuity won't apply. Like, for instance, Newton's laws. $\endgroup$ – user107153 Jan 8 '18 at 18:10

 $\begingroup$ Don't understand either.... What's the author's definition of manifolds? Strictly speaking manifolds should always be finite dimension, right (of course you could generalize to infinite dimension but that's the generalization...)? So even "manifolds" on Hilbert space are not manifolds... $\endgroup$ – Kite.Y Jan 8 '18 at 18:36

Consider a pair of points $P$ and $Q$, say of mass $m>0$, and suppose that they are constrained as follows.
 1. $Q$ stays on the $z$ axis and can freely move along it up to restrictions said below.
 2. $P$ can freely rotate around $z$ and is connected to $Q$ by means of an ideal rod (zero mass) of length $\ell$, and it is also connected to the origin $O$ by means of another ideal rod of length $\ell$.
This is a quite standard idealized mechanical system (I could use it as a starting point for an exercise of my undergraduate course of Analytic Mechanics).
A suitable coordinate system to describe the system is apparently given by the signed distance $Z\in (-2\ell, 2\ell)$ of $Q$ from $O$ along $z$ and an angular coordinate $\theta\in (-\pi,\pi]$ describing the position of $P$ around $z$ in the plane $x,y$.
Well you see that, discarding the extreme points $Z= \pm 2\ell$ (they could be included with a more precise discussion, see the ADDENDUM) a disaster shows up when $Z=0$.
Concerning the set $Z\in (-2\ell, 0)$ and $Z\in (0, +2\ell)$, the space of configurations is diffeomorphic to $\mathbb R \times \mathbb S^1$. When $Z=0$ the configuration space (at fixed $Z$) instead of being $\mathbb S^1$, it becomes $\mathbb S^2$ and another set of coordinates should be used.
There are two possibilities: either declaring that the configuration space is diffeomorphic to $\mathbb R \times \mathbb S^1$ deliberately ignoring the problem at $Z=0$, or declaring that it is not a ($2$-dimensional) manifold (because each point in the subset at $Z=0$ has a neighborhood that is not diffeomorphic to $\mathbb R^2$), but is made of the union of three manifolds respectively diffeomorphic to $\mathbb R \times \mathbb S^1$, $\mathbb S^2$, and $\mathbb R \times \mathbb S^1$. In practice, with an imprecise but pictorical description (see the ADDENDUM for a precise description) it is the union of a cylinder and a sphere inside the cylinder, tangent to the cylinder at the equator. This is not a manifold because it is not locally homeomorphic to $\mathbb R^n$ for some fixed $n$ ($2$ in our case).
Generally speaking the space of configuration is almost always a manifold because it is obtained by imposing constraints on a set of $N$ matter points initially described in $\mathbb R^{3N}$. Constrains are determined by a family of $c< 3n$ real-valued functions $f_k = f_k(t,\vec{x}_1,\cdots, \vec{x}_N)$ by imposing that every admissible configuration $\vec{x}_1,\cdots, \vec{x}_N$ at any time $t$ must satisfy $$f_k(t,\vec{x}_1,\cdots, \vec{x}_N) =0\:, \quad k=1,\ldots, c\:. \tag{1}$$ If the functions $f_k$ are smooth and functionally independent, the theorem of regular values proves that (1) defines an embedded submanifold of $\mathbb R \times \mathbb R^{3N}$ of dimension $1+ 3N-c$. Fixing time $t \in \mathbb R$, we have an embedded submanifold of $\mathbb R^{3N}$, of dimension $3N-c$, called space of configurations.
The two conditions of the constraints may be false for some points and it sometimes happens in particular when dealing with constraints like rigidity in some geometrically involved way.
ADDENDUM. If $X,Y, Z$ denote the coordinate set of $Q$ and $x,y,z$ the coordinate set of $P$, both in the whole $\mathbb R^3$ space, the four constraints, corresponding to the set of conditions 1 and 2 above, read
$$f(x,y,z, X,Y,Z)=0\:, \quad g(x,y,z,X,Y, Z)=0\:, \quad h(x,y,z, X,Y,Z)=0, \quad i(x,y,z, X,Y,Z)=0\tag{2}$$ where $$f(x,y,z, X,Y, Z) := x^2+y^2+z^2 -\ell^2\:, \quad g(x,y,z, X,Y,Z) := x^2+y^2+(z-Z)^2 -\ell^2\:, \quad g(x,y,z, X,Y,Z)= X\:, \quad i(x,y,z, X,Y,Z)= Y\:.$$ These constraints are functionally independent if, by definition, their differentials are linearly independent on the set of points $(x,y,z,X,Y, Z)$ where all conditions (2) are valid.
In this case theorem of regular values implies that this set is an embedded submanifold of $\mathbb R^3 \times \mathbb R^3$ with dimension $6-4 =2$. It is clear by direct computations that the four differentials are not linearly independent (because $df=dg$) when $Z=0$. This is the problem with the said system of constraints.
A precise description of the configuration space when including also the points $Z= \pm 2\ell$ is the union of two $2$-spheres in $\mathbb R^4$ that have an equator in common.

What I wrote arises from my undergraduate lectures (I teach also Lagrangian and Hamiltonian Mechanics though my research field is QM and QFT). $\endgroup$ – Valter Moretti Feb 27 '18 at 10:29

- janitor •
Part of Speech: Noun
Meaning: 1. A door-keeper, porter, ostiary. 2. A caretaker or custodian of a building.
Notes: We think today's word is still a good one despite the fact that it has fallen into the disrepute of political incorrectness. Those of us sensitive to the political whims in language in the US today refer to janitors as custodians. Janitor has an adjective, janitorial, and the position of a janitor is a janitorship. We think this word should never have been carted off to the PC cellar.
In Play: When we replace names that we think have become unrespectable, however, the general result is that the replacement soon acquires the connotation of disrespect. It would be difficult to find a designation for custodians with a more sterling pedigree than janitor, though: not only is it based on the name of a Roman god, beginning in the 17th century Saint Peter himself was sometimes called "the Janitor of Heaven".
Word History: Janitor comes to us directly from Latin ianitor "doorkeeper" based on the word ianus (janus) "archway, gate". The god of doorways and the New Year in ancient Rome was also called Ianus (Janus). Because he was the god of beginnings and endings, he was represented over Roman doorways with two faces looking in opposite directions. The only remains of this association is in Portuguese, where janela means "window". The month of January was also named after him. The name is based on the Proto-Indo-European root ei- "to go", found today in Russian idu "I am going". Latin ire "to go" and iter "journey", visible today in the English borrowings iterate, itinerary, and itinerant, are descendants of the same PIE root.

Home > Articles > How Cops can Stay 'Left of Bang' in a Critical Incident
"Left of bang" is a concept (and a book by Patrick Van Horne and Jason Riley) which can be described as a timeline. It's the time before a critical incident can no longer be contained. As soon as the IED goes off, the shot is fired, or the crash takes place, you are at bang. "Right of bang" is where police officers do not want to be. Left of bang is about situational awareness and keeping things from getting to bang.
I have recommended Gavin de Becker's book The Gift of Fear to cops and civilians for years and now must recommend Left of Bang as a companion book. The more training and experience people have in developing situational awareness, the better adept they are at staying left of bang. Here are some key ways cops can stay left of bang.
1. Treat people with respect
2. Use contact/cover and backup
3. Sharpen your situational awareness
4. Remember "Ask, Tell, Make"
5. Prepare to use force without hesitation or fear

Did Active Labour Market Policies Help Sweden Rebound From The Depression Of The Early 1990s?
Source: Princeton University
In the early 1990s the Swedish labour market was hit by the worst shock it experienced since the 1930s, with the unemployment rate rising to 10 percent. This development stands out in light of Sweden's performance in the post-war period. Between the mid 1940s and the crisis of the 1990s, the Swedish unemployment rate oscillated between one percent and just under four percent (Figure 1). Unemployment even remained low in the 1970s despite oil price shocks that led to persistently high unemployment elsewhere in Europe.


page object with Playwright if sharing one is not an option (it usually is). You can test single-page applications without model classes, but they offer a significant productivity boost for testing more complex routes.
Generate Code by Recording Browser Actions
Suppose your usual routine when writing new tests is to open the browser developer tools and search for CSS selectors to add into your tests. In that case, you are delighted to know Playwright supports recording and code generation via a command-line tool.
If we want to record actions done in the English Wikipedia, for example, it's as easy as running the following line in your terminal:
npx playwright-cli codegen -o test.js
Enter fullscreen mode Exit fullscreen mode
Using the npx tool part of Node.js, this command downloads the Playwright CLI tool and opens your browser in a recording mode. The -o test.js part is used to stream the generated code to standard output (your terminal) and save it to a file.
In the browser, let's now fetch a random article from Wikipedia, "read" it, and navigate back to the main page. After closing the recording, we have received this code ready to be saved for further inspection.
const { chromium } = require('playwright');
(async () => {
 const browser = await chromium.launch({
 headless: false
 const context = await browser.newContext();
 // Open new page
 const page = await context.newPage();
 // Go to
 await page.goto('');
 // Click text="Random article"
 await'text="Random article"');
 // assert.equal(page.url(), '');
 // Click //a[normalize-space(_USER_)='Visit the main page']
 await'//a[normalize-space(_USER_)=\'Visit the main page\']');
 // assert.equal(page.url(), '');
 await context.close();
 await browser.close();
Enter fullscreen mode Exit fullscreen mode
What is incredibly impressive is that the code is clearly structured, annotated, and wrapped as an asynchronous instantly invocated function. It even suggests places for writing test expectations with assert.equal(). If you have Playwright installed globally or in a project, you may repeat the previous actions by running node test.js.
From here, you likely want to fine-tune the selectors to be more user-friendly, which is a trivial task given your application has a sensible frontend structure.
Portability and Automation
If you work on a general-purpose test suite, you may sprinkle a little bit of portability into the cake by using the official Docker image provided by Microsoft.
Writing tests is never enough if they only run locally. Playwright supports most of the Continuous Integration solutions out of the box, including Travis, Jenkins, Circle CI, and GitHub Actions. For the latter, you may also use the official GitHub Action.
Closing Remarks
Lately, I've started working with an extensive e-commerce application where a robust end-to-end testing suite is worth every penny. We have established an Azure cloud platform development environment and plan to run tests nightly and after deploying a new application version. This lifts tons of manual testing and stresses off our backs.
With Playwright, I drafted an initial test suite by recording a user flow and refactored it to page object models. After a couple of hours, I had a full-featured test suite which works as a regression test when I want to ensure my changes haven't broken anything. I have a new hammer, and I intend to use it everywhere.
Have you used Playwright for testing your application? Let me know in the comments how it went.

Severance Pay & Connecticut Unemployment Benefits
When you receive severance pay as your employer terminates you, the Connecticut Department of Labor (CTDOL) doesn't automatically disqualify you from unemployment benefits. Instead, the agency treats that pay as income and uses the state's formula to calculate how much, if any, unemployment payments you're still entitled to. After your severance pay runs out, you begin collecting normal payments. As long as you report your severance pay during the unemployment claims process, you'll receive the correct amount. However, if you conceal your severance pay so you can collect more unemployment, you'll face stiff penalties from the Connecticut government.
Severance Pay
When your employer offers you severance pay, it's to offset the fact that you're losing your job. By offering you a few extra weeks of salary payments, your employer hopes to soften the blow of termination. When you get your last paycheck from the employer, it will have additional weeks of income on it above what you earned through work.
Reporting Severance Pay
When you make your claim to the CTDOL, you must report your severance pay. The reason is that severance pay is still considered income. Although collecting income doesn't disqualify you from Connecticut unemployment benefits, it may change your eligibility. During your initial application process, you must answer the question about severance pay truthfully and explain how much money you receive from. Afterward, when you file your weekly claim, you must note any weeks you've earned severance pay. The CTDOL will calculate your eligibility depending on your answers.
Calculating Partial Payments
If you earn severance pay a week in which you're also eligible for Connecticut unemployment benefits, you can still collect partial benefits. To determine how much your unemployment payment should be, the CTDOL takes two-thirds of your severance pay before any deductions such as taxes. They then subtract the result from your normal weekly payment. You receive the rest, if any, as a payment. When your severance pay runs out, your unemployment benefits stop being partial payments.
Failure to Report
If you don't report your severance pay, you are committing insurance fraud. The CTDOL verifies with your employer at the beginning of your claim and does random audits of files through your benefit year. If you are ever found withholding, concealing or misrepresenting information about your income, you can face severe penalties. Connecticut punishes this crime by forcing you to repay your benefits back and penalizing you up to an 39 additional benefit weeks. This means that the next time you qualify for unemployment, you have to serve these weeks with no payment. In some cases, you can receive fines of up to $5,000 and between one and five years of jail time.

In this section, we have explained in detail the concept of spiritual research.
In simple terms, spiritual research is researching the spiritual dimension or spiritual realm with the help of an advanced sixth sense (ESP). The spiritual realm is that which cannot be perceived through our five senses, mind and intellect. It includes the world of heaven, hell, angels, spirits, auras, ghosts etc.
The source of knowledge in this website is the Universal Mind and Intellect, which is God's mind and intellect. It is accessed through the medium of a highly advanced sixth sense.
We have divided this section into three parts to explain the concept of spiritual research:

Claims are the structured description of the unique elements of a patented technology. The claims in a patent application are the specific pieces that are examined and eventually approved by a patent examiner to define the scope of an invention. Thus, the claims of a patent, rather than the description, serve the practical purpose of defining the elements that are protected. This also means that the claims are the pieces that are targeted in invalidity searches, to prove that they existed previously.
In practice, the patent claims enable the practitioners in the field of the invention to determine whether or not a product or process can be considered to fall under the invention protected by a patent. The scope of the granted claims may be as broad as those of the patent claims initially submitted by the patent applicant for examination, or they could be substantially restricted in scope or number by the examiner based on the available prior art.
Claims in AOP Studies
In many cases, AOP Studies focus on a particular claim or set of claims in the Study patent that are of significant interest. This is because the issues of Invalidity and Patentability are largely based on whether the claims in the patent or application are indeed novel and non-obvious. The particular claim then becomes the primary basis for the choice of initial keywords used in a search.
For your submission to serve as prior art for a given Study patent, the reference needs to disclose as many of the features in the claims of the Study patent as possible. For example, consider that the following claim (1) is the primary focus of the Study:
1. A composition for extending the durability of car paint comprising:
– low-molecular weight polyethylene polymers
– ultraviolet light stabilizer
– titanium oxide nanoparticles
In this case, the winning reference would describe the claim and all four of the additional features, or "elements." If your reference only has one or two of the elements, it may still be useful, but it is less likely to win the Study. Also consider that the reference cannot simply contain all of these keywords. In this example, the keywords must fit together to represent a car paint that consists of each feature together.
Independent vs. Dependent Claims
Independent claims are solitary claims that do not need any further explanation, whereas dependent claims include the details of the corresponding independent claim. Independent claims represent the foundation of the technology, while dependent claims provide additional detail about the features and aspects that make the basic technology unique and different from anything else.
The example in the above section represents an independent claim. The claim describes a technology that improves car paint, and it defines four specific features. This full claim can stand on its own without any necessary support.
Claim 2 below is an example of a dependent claim, which depends on claim 1 above:
2. A claim according to claim 1, wherein the ultraviolet light stabilizers comprise nitrogen-containing bicyclic rings.
By definition, the dependent claim contains all of the features and details of the independent claim on which it depends. Thus, claim 2 includes all the four features of claim 1, plus the additional pieces described in claim 2. The main difference is that claim 2 is narrower than claim 1 based on those additional features. Thus, if an AOP Study points to a dependent claim, it is important to remember that all of the features in the independent claim also apply to your search.

Robber flies eat biting flies and other flying insects like bees, butterflies and wasps. This species likes bees and dragonflies best as well as biting flies. During the day, they literally hang from branches or objects near the ground with their front legs, waiting to ambush passing prey. They are fast and noisy fliers, giving chase to insects that are already in flight. When they overtake them, they grab them with their legs to stop them from escaping. Once captured, the robber fly will stop at a branch or leaf and use its stiff mouth to pierce the body of its victim and then suck out the victim's insides.
They make a loud whirring noise as they fly because they beat their wings so quickly. They may be mistaken for a bee or a wasp because of their size and the buzzing noise they create.
Robber flies come in a variety of species. The ones from the Diogmites genus have a few color variations and different striped markings on the abdomen per individuals.

[dm-devel] [PATCH 1/7] blkio-cgroup: Introduction
Hi all,
This is a new release of blkio-cgroup which provides an IO tracking
mechanism. You can also download this series of patches from
Changes from the previous release
- bio-cgroup renamed to blkio-cgroup.
- Use part of page_cgroup->flags to store the blkio-cgroup ID.
 This code is taken from Andrea's io-throttle.
- Add a new function blkio_cgroup_lookup(ID) which can be called from
 other cgroup subsystems and return the cgroup associated with a
 given blkio-cgroup ID. It makes it easy to use blkio-cgroup from other
 cgroup subsystems.
- Add an extra patch which reduces the overhead of IO tracking.
- Can be applied to 2.6.30-rc3 and 2.6.30-rc3-git3.
What's blkio-cgroup all about?
With this feature, you can determine the owners of any type of
I/Os. This makes dm-ioband_--_I/O_bandwidth_controller_-- be able to
control the Block I/O bandwidths even when it accepts delayed write
requests. Dm-ioband can find the owner cgroup of each request. It is
also possible that the other people who work on the I/O bandwidth
throttling use this functionality to control asynchronous I/Os with a
little enhancement.
Setting up blkio-cgroup
You have to apply the patch dm-ioband before applying this series of
blkio-cgroup patches.
And you have to select the following config options when compiling
And I recommend you should also select the options for cgroup memory
subsystem, because it makes it possible to give some I/O bandwidth and
some memory to a certain cgroup to control delayed write requests and
the processes in the cgroup will be able to make pages dirty only
inside the cgroup even when the given bandwidth is narrow.
Using blkio-cgroup
The following shows how to use dm-ioband with cgroups. Please assume
that you want make two cgroups, which we call "bio cgroup" here, to
track down block I/Os and assign them to ioband device "ioband1".
First, mount the bio cgroup filesystem.
 # mount -t cgroup -o blkio none /cgroup
Then, make new bio cgroups and put some processes in them.
 # mkdir /cgroup/grp1
 # mkdir /cgroup/grp2
 # echo 1234 > /cgroup/grp1/tasks
 # echo 5678 > /cgroup/grp2/tasks
Now, check the ID of each blkio cgroup which is just created.
 # cat /cgroup/grp1/blkio.id
 # cat /cgroup/grp2/blkio.id
Finally, attach the cgroups to "ioband1" and assign them weights.
 # dmsetup message ioband1 0 type cgroup
 # dmsetup message ioband1 0 attach 2
 # dmsetup message ioband1 0 attach 3
 # dmsetup message ioband1 0 weight 2:30
 # dmsetup message ioband1 0 weight 3:60


Defining programs
Programs are managed from the "Workspace" area on the left of the Workbench main window. To work with programs, activate the workspace area and select the "Programs" tab in it.
Here you can declare an manage the programs and User Defined Function Blocks (UDFBs) of your application. The workspace shows the list of all programs and UDFBs, initially sorted by alphabetic order.
Creating programs
Press this button in the toolbar for creating a new program. You have to select its language at this time. The programming language of a program can be changed later by converting the program. You can also declare a child program for a selected SFC program.
When you create a program or UDFB, you have to enter its properties. A wizard guides you for defining:
- the identification and main attributes of the program
- its advanced parameters for its execution at runtime
- its description
The same box can be used later to rename a program, change its properties and its description.
The box also includes a wizard for defining/arranging input and output parameters in case of a UDFB or sub-program
The program property box can also be used for protecting the program against editing.
Programs must have unique names. The name cannot be a reserved keyword of the programming languages and cannot have the same name as a standard or "C" function or function block. A variable should not have the same name as a declared variable The name of a program should begin by a letter or an underscore ("_") mark, followed by letters, digits or underscore marks. It is not allowed to put two consecutive underscores within a name. Naming is case insensitive. Two names with different cases are considered as the same.
Opening programs
Press Enter or double click on a program to open it with the appropriate editor. An open program cannot be renamed or deleted.
Copying programs
Use the "File / Copy" command for duplicating the selected program. Copy cannot be used for erasing an existing program. You must enter a new name for the destination of the copy.
Arranging programs in folder
Default workspace shows all programs in alphabetic order. You can freely arrange them in a tree by creating folders. Use the "New folder" command in the right-click popup menu to create a new folder. Simply click on its name to rename it. You can create several levels of folders.
Then, simply drag programs in folders to re-arrange the tree. Programs, sub-programs and UDFBs can be put together in the same folder. Within a folder, all items are sorted in alphabetic order.
Defining the execution sequence
Use the "Cycle" command in the context menu to define the execution order of various programs in a seperate box. The box shows the list of the main programs, as they will be executed in runtime cycles. You can:
- use the "Move" buttons to change the order of the programs within the cycle.
- use the "Select" buttons to specify if the program must be called in the cycle. Unselected programs are not kept at compiling time, and are shown with a "red cross" icon in the workspace.
- use the "Increase/Decrease" buttons when the "Period" or "Phase" column is selected to change the scheduling of a program. This enables you to define "slow" programs that are not called on every cycle. See the "Program advanced properties" for further details.

Bariatric ground transport is a form of medical transportation specifically designed to meet the needs of bariatric patients. This kind of transport is designed to offer the comfort and safety that traditional transport may fail to provide. Patients are considered to be bariatric if they have a Body Mass Index (BMI) of 30.
Consequently, a bariatric patient's weight and size often make it uncomfortable and unsafe to transport them via traditional ambulances not explicitly designed for such purpose.
As such, special transportation that can meet the patient's requirements have to be used. Bariatric ground transport companies now offer special transportation services that are ideal for transporting bariatric patients. However, there are some factors to consider when choosing a bariatric ground transport company. Below are a few of the major factors to consider.
1. Level of Care Required
Some bariatric patients are reasonably mobile and can move or be moved with relative ease. Others might be bedridden and require more assistance to move safely. Equally important is the level of medical attention that the patient would often require in transit. Some basic medical care is enough in some instances, while others require advanced medical attention even in transit. Therefore, it's imperative to choose a company that can provide the needed level of care.
2. Type of Vehicle
Another vital factor to consider when choosing a bariatric ground transport company is the type of vehicles available. Large vehicles with wide doors are needed to accommodate bariatric patients. Other essential factors to note are the weight and size limitations. It's important to verify that the vehicles can transport a bariatric patient safely and comfortably.
3. Equipment Condition and Suitability.
To successfully transport a bariatric patient, a bariatric ground transport service must have the right equipment to accommodate and serve a bariatric patient. For instance, intramuscular injections must be done with longer needles, and blood pressure cuffs must be in the appropriate size.
Furthermore, the wheelchairs and stretchers must also be specially designed for bariatric patients. Overall, equipment must be large-sized and suitable for bariatric patients to facilitate the smooth movement of the patient. Weight limitations of lifting equipment like stretchers and wheelchairs must also be considered.
4. Availability of Door-to-Door Service
It is important to verify whether a particular bariatric ground transport company offers door to door service. It would be difficult and inconvenient if the patient has to be moved to a different location before being transported. Therefore, it is necessary to confirm if they offer door to door service before hiring them. In some cases, a company might even provide bed-to-bed services.
5. Personnel Capability and Competence
Transporting a bariatric patient requires more personnel. In fact, a minimum of four individuals must be available to move a bariatric patient safely. As such, you must choose a company that has adequate personnel for the trip.
Also, there are guidelines and algorithms that are designed to guarantee the safety of both patient and personnel in the course of transporting a bariatric patient. Specifically, Bariatric Algorithm 6 details the procedures for transporting a bariatric patient. Hence, it is necessary to consider the knowledge and competence of the personnel before opting for any bariatric ground transport service.
The factors highlighted in this article will help you choose the right medical transport company; that offers a seamless bariatric ground transport service that guarantees the safety and comfort of the patient at all times.

Faeces, electric eels and fruit would power conceptual communities designed by Bartlett School of Architecture graduate Catrina Stewart.
The City Farmhouse project proposes housing communities on stilts above clusters of public toilets, where visitors would be required to donate faeces and urine on arrival.
Electricity would be generated from methane gas released when the harvested excrement is broken down.
Faeces and urine could also be used to produce compost and water for community gardens.
Streetlights would be powered by fruit acid and elevators would be powered by electric eels, kept as pets by residents.
Other recent architecture graduate projects include an upside-down skyscraper and a tower that shoots artificial bees into the air - see all our stories about this years graduate shows here.
Here are some more details from Catrina Stewart:
London City Farmhouse
The City Farmhouse project is a prototype that looks at forming new self-sufficient communities, which integrate agriculture and housing within the city of London.
The Farmhouses and vertical colour gardens will be open to the public, and will rely on its colours and visitors to achieve self-sufficiency.
Visitors and residents will be expected to make a donation of faeces and urine when they visit the building. These will be used to produce water, compost and electricity for the Farmhouses. Methane gas released by the waste produced in biogas digesters can then be used directly or to produce electricity.
Without its public toilets the community would not be able to survive. The more visitors the building can attract the more power, food and water will be produced. New public toilets will be erected across the borough in order to collect human waste to power the Farmhouses. New communities will begin to grow around the more popular public toilets, creating new Farmhouses.
The Farmhouse project explores the use of colour to attract people to the building and entice them into using the public toilets by using the same principles used for colour in marketing and advertising. Colours are therefore used less for their aesthetics and more for their functional properties.
Nothing in the Farmhouse is disposed of, everything is recycled and reused to fuel something else. Old and new technologies are used to harness energy and food from almost anything, animals are no longer used for their meat but rather as a source of energy.
Cows are farmed for their methane gas, electric eels are kept as pets to power the elevators in the building and fruits are used to to power the street lights.

It covers approximately 400 ha, which is a relatively large woodland for the UK and includes a range of different soil types and management histories. Wytham is owned by Oxford University and is used by the Centre for Ecology and Hydrology (CEH) as a long-term monitoring site in the UK Environmental Change Network (ECN). A flux tower has occasionally operated on the site, measuring stand-scale carbon and water fluxes; a canopy walkway gives access to the leaves of canopy trees, and several studies of tree ecophysiology have been carried out there. A network of small (10 m x 10 m) ECN forest-monitoring plots is distributed across the site, and a 1-ha plot forms a focus for carbon-dynamics studies, including soil processes and tree growth. The core ForestGEO plot covers 18 ha (300 m x 600 m), and has been surveyed in detail by airborne lidar and hyperspectral sensors, and by terrestrial lidar.

Consider $G = GL_n( \mathbb{Q}_p)$ and $K = GL_n( \mathbb{Z}_p)$, or more favorable replace $ \mathbb{Q}_p$ by a non archimedean field and $\mathbb{Z}_p$ by the ring of integers.
Note that the space $G //K$ is discrete, since $K$ is open and closed in $G$.
Given a Haar measure on $G$, I can prove that there exists a unique (discrete) measure on $G//K$, such that $$ \int\limits_{G} f(g) d g = \sum\limits_{x \in G//K} w(x) \int\limits_{K \times K} f(k_1 x k_2) d k_1 d k_2.$$
How can $w$ be expressed, if we pick a representative $x = diag( w^{k_1}, \dots, w^{k_n})$ for a uniformizer $w$?
Perhaps easier, but equivalent what is the ratio: $vol_G (K xK)/ vol_G(K)?$
(More out of curiousity: How is the Plancherel measure related to this?)

You are dealing with the integral formula for the Haar measure on $G$, associated with the Cartan decomposition $G=KAK$. Since the Plancherel measure lives on the dual object $\hat{G}$, I don't see any obvious relation between the two. – Alain Valette Dec 17 '11 at 22:05

The measure of $KxK$ is a classical computation that may be found in: Macdonald "Symmetric Functions and Hall Polynomials" (Oxford Mathematical Monographs), more precisely in Chapter V: The Hecke ring of ${\rm GL}(n)$ over a local field.

Depending on taste, one might also find appealing or helpful the description of this in terms of the Iwahori-Hecke algebra, with affine Weyl group and affine cartan decomposition $G=\bigcup_w BwB$ where $B$ is the Iwahori. Among other features, this does give a way to inductively determine the measure of $BwB$, once the measure of $B$ is normalized, because there is a precise cell-multiplication rule $BwB\cdot BsB=BwsB$ when the length of $ws$ is strictly greater than that of $w$, and $s$ is one of the affine reflections generating $W$. That is, the length in $W$ is equivalent to knowing the measure of the Iwahori coset.
(Inevitably, surely MacDonald's discussion does something equivalent to this, but I don't remember, and I don't have a copy accessible to me.)

I checked the other answer, because it directly answers my question, but your suggestion seems a lot more suitable for my purposes than the ''naive'' KAK decomposition I was aking about. Do you have a reference for this? Thanks a lot for mentioning this. – Marc Palm Dec 18 '11 at 10:04
_USER_, In my "Buildings and Classical Groups" book, (math.umn.edu/~garrett/m/buildings/book.pdf) chapter 5 exactly treats this: it is simply the BN-pair (with corresponding Bruhat decomposition, etc) attached to the affine building. Probably any book on buildings mentions this at some point. In some sources, the cell multiplication rule is an "axiom". In my chapter 5 I prove that it follows from the building properties. – paul garrett Dec 18 '11 at 15:01
So just to confirm that I understand what you are saying notationwise: In your notation $B$ is the pullback of the Borel subrgoup $B'$ in $GL(n, o/p)$ along the projection $GL(n,o) \rightarrow \GL(n, o/p)$ and $w$ runs through the normalizer of all diagonal matrices $M$ (=affine Weyl group $MW$?). This is called affine Cartan decomposition? What is $N$ in the $BN$ pair, if $B$ is the Iwahori? ($N=MW$?) I am rather fine with using axioms, but it usually gives me a headache to verify that they hold for specific examples. – Marc Palm Dec 18 '11 at 16:53
_USER_: Yes, in this situation, $B$ can be described as the inverse image in $GL(n,o)$ of the Borel in $GL(n,o/p)$. Yes, the affine Weyl group is normalizer of diagonals, modulo diagonal unit matrices. In my book/notes I verify (as did Bruhat and Tits ages ago, maybe it's in Bourbaki Lie ch. iv-...?) that the affine building for $SL(n,k)$ can be constructed via homothety classes of lattices. Then the building properties prove an abstracted Bruhat decomposition. One can also prove, following Tits, that the Coxeter-group property follows from the building set-up. – paul garrett Dec 18 '11 at 18:22

Here is the problem:
Let $S$ $\subset$ $\mathbb{R^{3}}$ be a regular surface with the property that all normal lines meet the z-axis. Prove that S is contained in a revolution surface around z.
I first tried to prove that every curve contained in this surface with a fixed z-coordinate is a circle (by showing that all normal lines to this curve meet at a point, it's a previous exercise), but the normal vector to the surface and to the curve are not the same, and I didn't go further... can you help me?

Sounds like you have a good strategy. You are looking at the cross section in some plane $z=z_0$, and you want to prove that the cross section here is a circle.
You are given that any normal line will intersect the $z$ axis. Let's write this line as $\vec{p}+\vec{n}t$ where $\vec{n}$ is the normal vector at the point $\vec{p}$ we are discussing. You can then show that a new line $\vec{p} + (\vec{n}-\hbox{proj}_{\hat{z}}\vec{n})t$ will also intersect the $z$ axis (taking away the z component doesn't change the fact that the line is in a radial direction).
Moreover, this new line will be normal to the cross section at $\vec{p}$: the tangent plane projects to a tangent line of the cross section, so must a normal vector of the surface project to a normal vector of the cross section.
This gives you the criteria you wanted -- all horizontal lines orthogonal to cross sections will intersect at the origin. This tells you roughly that the cross sections are circular, and that the overall shape will be a surface of revolution.

How Do You Fold A Document That Has Been Laminated?
1 Answers
Arjun Mitra Profile
Arjun Mitra answered
The answer to this question depends on how hard the laminated surface is. If the laminated surface is hard enough for the document to not fold, you have no choice left. You will just have to go about not folding the document or go ahead remove the lamination. Some laminations are soft in texture and can be easily folded. But once they are folded the folds will leave a permanent mark on them which will never go away.
So if you are looking to fold a laminated document then it is advisable not to do so as you could cause harm to it. What you could do is get files or folders or envelops that are bigger in size of the document and you will not have to fold the. Just avoid the idea of folding a document especially if it is an important one.

Dissolving Hot/Cold
See if candy dissolves faster in hot or cold water.
Red Skittles in hot water dissolve faster
than orange Skittles in ice water
What you need:
 - Identical pieces of candy
 - Hot and cold water
 - Cups
What to do:
 1. Fill one cup with hot tap water and one with cold water (for better results, add ice cubes).
 2. Put one candy in the hot cup and one in the cold cup.
 3. Watch to see which dissolves faster.
What's happening:
Because molecules move faster when it's hot, the candy in hot water dissolves much faster. The candy in ice water might take all night to dissolve.
With chocolate, the difference is even more impressive. Since the cocoa butter in chocolate doesn't dissolve in water, chocolate placed in cold water just sits there. But chocolate in hot water melts and mixes with the water.
 1. this expermint was such fun!! Thanks for the info. I recomnd doing this one!
 2. How Do I make a data graph on this?
 3. You could try graphing how long it took for Skittles shells to dissolve in different temperatures of water. It happens pretty fast, and it's something that you could probably put a pretty clear end point on--when the shell is gone, the white layer underneath is exposed. Otherwise you could try dissolving just about anything in various temperatures of water, just make sure that each cup contains the same amount of water and you put in the same kind of candy.
 4. My class did this experiment this week. We ended up leaving them over night to witness them dissolve all the way. My kids LOVED this experiment. I have recommended it to all of my teammates. Thank you so much
 5. Try using something with a colored shell that dissolves quickly, like Skittles, M&M's, or Nerds. Smarties and Conversation Hearts don't work as well.

A while back in this thread, before Eric Chan pointed out that there were two image processing pipelines in Lightroom and that all my integer TIFF testing wasn't really relevant to raw processing, some of you asked about different error measures than CIELab Delta-E, specifically something related to hue errors. These color difference measures can get quite complicated. Here's an example
. I can, if there's sufficient interest, implement some of these more complex, and presumably, accurate, measures, but I'll present here just the basics. In the precious post, I presented the Delta-E curves.
Here's a set of Delta-H curves, the basic CIEL*a*b* difference metric that measures hue error:
Like Delta-E, Delta-H can't go negative.
Here are the Delta-C curves, which measures differences in what's called "metric chroma", the radial distance from the grey axis:
Delta-C is positive if the test color is more chromatic than the reference, and negative if the test color is less chromatic than the reference. The fact that there's a tendency towards positive Delta-C indicates that making positive LR exposure adjustments tends to make the colors more chromatic than they should be. You can see that from the scatter plots as well.
If you look at the numbers in the Delta-H and Delta-C plots, you can see that most of the chromaticity error comes from too much chroma, not from hue shift.
And, although it's not a CIELab standard, I like to look at hue angle errors. The big potential problem with looking at hue angle alone is that errors near the grey axis, where they are inconsequential, can have the same value as errors in highly chromatic colors, where they are significant. Still, it gives indications of any possible hue shift bias. Here is the hue angle data:

20. Christian Headstone with Canopy
Yuan dynasty (1272—1368)
Quanzhou Maritime Museum
Ricci 20 KP 020 Z24
A canopy or parasol was used in ancient India to protect kings and other royals from the sun, and it subsequently became a symbol of power and prestige. It was natural to use a canopy in association with the Buddha as he had been a prince before attaining enlightenment. It can be seen in the early Buddhist art of India, and was transmitted to Central Asia and China where it appears, for example, at Dunhuang. A similar canopy to the one shown on this tombstone can be seen on a panel relief on the Eastern pagoda of the Kaiyuan Temple in Quanzhou, completed about 1250.
The discovery of the canopy's presence on Christian tombstones of the Mongol period is quite remarkable, and yet explicable in the context of the multiculturalism of Quanzhou. The canopy has tassels or streamers dangling from it and protects the cross emerging from an open lotus flower.


text: This article examines shifts in attitudes and changes in provision with regard to never–married mothers within three broad chronological periods. The first section considers attitudes towards these mothers in the period 1918–45, when the issue was conceptualized as one of public health and moral welfare. Second, the article examines the period between 1945 and 1970, when the dominant professional view of never-married mothers focused on identifying individual pathology, but when significant continuities in treatment can nevertheless be found. Third, the article looks briefly at the substantial change in policy and provision for what were then called 'one-parent families' during the 1970s. In conclusion it argues that while there were substantial changes in terms of the way in which unmarried motherhood was defined, from the point of view of the unmarried mothers themselves the continuities have been more striking. Unmarried mothers have been persistently singled out and labelled a social problem and, in all but a brief period during the late 1960s and 1970s, also as a moral problem.

I have needed a utility to efficiently "empty out" a SQL Server database several times over the last few years and also have talked to other developers that agreed such a utility would be helpful. I present such an application here in this article for your use. Since it generates explicit actions in a script, it is very easy to see exactly what will happen and have a good comfort level with those actions before running it. I hope this utility enhances your professional toolbox.
Please let me know your experiences using this application, including any enhancements that you think would be useful. Would you like the code placed somewhere that you and other readers could contribute to enhancing it? Enjoy!


What Happens To A Person When He Transcends The Machsom?
Laitman_032_01Question: What happens to a person when he transcends the Machsom (barrier)? Does he enter a new dimension?
Answer: Yes, a person exits his egoistic intentions and enters altruistic intentions, which enables him to feel what is external to him, outside of his natural perception.
Question: What actually happens to a person?
Answer: It is the revelation of a new dimension in new attributes of love and bestowal that are above human nature that a person acquires by his efforts to connect to the friends who study the wisdom of Kabbalah with him in a group. The change that takes place in a person is actually a person's spiritual birth and the attainment of the soul.

What Is Gross Sexual Imposition?
By Staff WriterLast Updated Apr 16, 2020 9:05:32 AM ET
A person who forces another person to have sexual contact with a third party has committed gross sexual imposition. In the state of Ohio, gross sexual imposition is a third or fourth degree felony charge, depending on the circumstances.
The crime of gross sexual imposition entails the forced sexual contact between two or more people, none of which are the offender. One example of such conduct would be forcing someone to engage in prostitution. To accomplish this, the offender may use, or threaten to use, force or intentionally impair the victim's judgment. Drugging a victim, or waiting until their judgment is impaired by the use of drugs or alcohol, then forcing or coercing them into sexual contact with a third party is another example of gross sexual imposition. Additionally, forcing or coercing a person who is physically or mentally disabled to engage in sexual contact constitutes gross sexual imposition.


American Crested
American Crested Breed Profile
Fur Short, smooth, close, thick
Rosettes None
Characteristics White crown
Lifespan 4-6 years
Suitable for Beginners
Breed Characteristics
The American Crested is completely one color - apart from its characteristic white crest on its head! This is like a little white crown created by the whorl. This makes it easy to tell this animal apart from other guinea pigs, especially for beginners. The crown sometimes makes these little pets look angry or indignant. But they're just as peaceful and funny as the rest of them. The rest of the American Crested's short, soft fur is usually golden brown, red or black. It doesn't have any markings or patterns to its fur.
Guinea Pigs for First-Timers
American Crested guinea pigs are among the easiest guinea pigs to keep. You could even call them "beginner guinea pigs". Still, inexperienced pet owners should get plenty of information and get hold of a guinea pig guide. Just like all guinea pigs, the American Crested is on the shy side.
How can you tell the American Crested and the English Crested apart?
Both have a crest on their heads but only the American Crested's is always white. In the English Crested, this is always the same color as the rest of its coat. If they didn't have this tuft, they'd just be completely normal American guinea pigs.

The white crest isn't easy to breed, as the babies of two American Crested guinea pigs won't always have the same markings, e.g. they might have additional white patches.
Fur Care
Short-haired guinea pigs can mostly keep themselves clean as they wash themselves with their little feet. Their fur should therefore only be cleaned when the American Crested doesn't keep up its hygiene duties. You should use a plastic brush for this. Knots can't always be prevented, and should be carefully cut out with scissors. It's also important to regularly check their ears, eyes and nails - just like with any guinea pig.
Just like all guinea pigs, the American Crested needs a combination of fresh hay, grasses, herbs, vegetables, fruit, seeds and twigs. They also need fresh water daily.
Did You Know?
A "crest" is a crown or tuft.

- PPI-PACE is an online tool developed by eTrenchless Group Inc. that follows the design procedures in well-established
and accepted water standards (ANSI/AWWA C150/151, ANSI/AWWA C900, ANSI/AWWA C901, ANSI/AWWA C905, ANSI/AWWA C906,
- Per the recent AWWA and ANSI approvals of AWWA C906-15, the Hydrostatic Design Stress (HDS) of PE4710 is 1000 psi.
- Users can change the default values per project requirements.
- For Recurring Surge, PPI-PACE defaults to 4 fps for design velocity; the software allows for a 4-8 fps range.
- For Occasional Surge, PPI-PACE defaults to 8 fps for design velocity; the software allows for a 5-15 fps range.
- For Working Pressure, PPI-PACE defaults to 70 psi - which is the average working pressure in the US. The minimum allowable value in PPI-PACE is 40 psi.
- For Anticipated Recurring Surges, PPI-PACE defaults to 55 cycles (the minimum) per day per AWWA C900-07 and AWWA C905-10 (Appendix B/Design Example); this results in about 1 million cycles for a 50-year design life and about 2 million cycles for a 100-year design life. It was recommended by one consultant to design for 3.5 million cycles or 96 cycles per day at a 100-year design life. The minimum allowable value in PPI-PACE is the default 55 cycles/day.
- For Temperature, PPI-PACE defaults to 57°F which is the average water temperature in the US; the software allows 40-100°F; consult the manufacturer for other temperatures.
- For Minimum Design Life, PPI-PACE defaults to 100 years; the software allows a minimum recommended design life of 50 years.
- For Help, refer to Resistance of PE4710 Piping to Pressure Surge Events in Force Main Applications, PP XVI, Barcelona, 2012 and to UK Water Industry IGN 4-37-02 Design Against Surge and Fatigue Conditions for Thermoplastic Pipes
- The definition of pressure rating and pressure class differ between the implemented standards (AWWA C900, AWWA C905, AWWA C906, ASTM F714, ASTM D2241). The calculations on this site, provided by eTrenchless Inc., provide an unbiased interpretation of these standards so that an equivalent comparison of pipe materials can be conducted.
- Temperature derating factors for PE pipe in AWWA-M55 are limited to 100°F with a reference to manufacturers literature for temperatures greater than 100°F. ASTM F714 (PE) and AWWA-M23 (PVC) publishes temperature derating factors up to 140°F but these higher temperatures are not included in this design tool.
The design fatigue life for PVC is determined using the calculation method stated in AWWA C900 and C905 Appendix B using a 2:1 design factor. Data from tests with PE 4710 pipe are consistent with the UKWIR and Marshall/Brogden reports; see above reference and link to PP XVI Barcelona, 2012. For PE the design fatigue life is determined using fatigue curves provided in Marshall, G.P., Brogden, S: Final report of Pipeline Innovation Contract to UKWIR, 1997 using a 2:1 design factor.
For additional information on fatigue life and flow velocities see the Jana Laboratories report here. The design fatigue life of Ductile Iron (DI) pipe is not shown in PPI-PACE since these calculations are not available or referenced in the DI AWWA Standards or Manuals.
- Pressure rating should be reduced for systems operating under special or unusual conditions or where the pipe transports fluids that are known to have some degrading effect on the properties of polyethylene or where specified in Codes or Regulations or by the authority having jurisdiction. Water is the assumed transport fluid on PPI-PACE.
- Occasional transients caused by emergency pump and valve operations are usually severe. The system should be designed to withstand positive and negative pressures caused by these emergency operations. Water column separation may occur if the negative pressure is reduced to the vapor pressure of the liquid. Rejoining of the separated water column typically results in a large pressure rise, which will possibly damage the pipe system. Whenever possible, water column separation should be avoided
- These are preliminary calculations for product comparison only, not for final design. Qualified professionals should be contracted to consider all aspects of the design for pressure pipe design.

Attila the Hun was the ruler of the Huns and leader of the Hunnic Empire from 434 to his death in 453. Though the details of his death are a little sketchy and several different accounts and theories have been presented, they all center around the cause of death being a nose bleed in early 453.
What is most often claimed is that Attila the Hun died of a nosebleed on his wedding night. He had just married a woman named Ildico. A going theory is that he died of a hemorrhoid in his esophagus which was caused by heavy drinking.
Chronic alcoholism can lead to acid reflux disease, which can lead to ruptures in the esophagus. This would mean it wasn't his nose really bleeding at all, but blood would still have been flowing out his nostrils and mouth. A
nother account claims that his nose suddenly began bleeding very severely during the wedding feast and in the ensuing confusion, he choked to death. One more theory is that he died of internal bleeding. There is also an account that claims his wife killed him, but most scholars reject it as hearsay.

Case 1: Workers has different rates
Work rate × Time to finish the job = 1 job done
Work rate = (1 job done) / (Time to finish the job)
Time of doing the job = (1 job done) / (Work rate)
Albert can finish a job in A days
Bryan can finish the same job in B days
Carlo can undo the job in C days
1/A = rate of Albert
1/B = rate of Bryan
1/C = rate of Carlo
Albert and Bryan work together until the job is done: (1/A + 1/B)t = 1
Albert is doing the job while Carlo is undoing it until the job is done: (1/A - 1/C)t = 1
Lejon can finish a job in 6 hours while Romel can do the same job in 3 hours. Working together, how many hours can they finish the job?
Case 2: Workers has equal rates
Work load = no. of workers × time to finish the job
Work done = no. of workers × time of doing the job
To finish the job
Work done = Work load
If a job can be done by 10 workers in 5 hours, the work load is 10(5) = 50 man-hours. If 4 workers is doing the job for 6 hours, the work done is 4(6) = 24 man-hours. A remaining of 50 - 24 = 26 man-hours of work still needs to be done.
Eleven men could finish the job in 15 days. Five men started the job and four men were added at the beginning of the sixth day. How many days will it take them to finish the job?

Social Media Used to Send Positive Message: _TAG_
BETHEL, Ohio (Adam Clements) -- Social Media can be a source of negativity and vicious bullying.
But now tri-state schools hope to use that same social media to spread positive messages to students. Local 12's Adam Clements gives us a look at a special initiative from the coalition for a drug free greater Cincinnati called, Your Live, Your Choice."
Ten years ago, if you got caught in class with a cell phone it usually meant a one way ticket to the principals office. In today's tech savvy world things like iPads and cell phones are actually encouraged, when they can be used for good.
Principal Susen Arn says it's a perfect way to reach her students in a language they can all understand.
Each day students at Bethel Tate High School will be given a message like this one, Be yourself, an original is worth more than a copy. They're encouraged to share that message on Facebook and twitter with the hashtag, _TAG_
Topics range from drugs and alcohol to how the students treat one another. A school administrator can only preach positivity so much. Susen says when her students hear the message from their peers, that's when she knows it's working.
Students who repost the positive message with the hashtag _TAG_ can actually win cash prizes. The program lasts through next Friday.

===== Insert text regarding state=QLD here. ======
A prank call, also known as a crank call or nuisance call, is a form of practical joke over the telephone. This includes threatening someone over the phone as well as hanging up the phone once the receiver has picked up the phone. Repeated prank calls can amount to harassment, stalking or even bullying. It is important to use common sense and realise that prank calls can cause fear and distress to other people.
Which types are prank calls are considered offences?
- Threatening to kill someone (not necessarily the person you called) over the phone with the intention that they will believe you.
- Threatening to cause serious harm to someone (not necessarily the person you called) over the phone with the intention that they will believe you.
- Threatening that you have left/will leave an explosive or dangerous object somewhere with the intention that they will believe you.
- If you menace, harass or cause offence to a person over the phone, either by what you are saying or the way you are saying it.
The penalties for making threatening calls can be very serious.
Calls to emergency services (000)
- Dialling '000' and pretending that there is an emergency. Penalty – 3 years imprisonment.
- Dialling '000' for a reason other than an emergency situation. Penalty – 3 years imprisonment.
The penalties for making prank calls to emergency services can be very serious.
Calls are not only considered to be prank calls when it is threatening. Other types of prank calls may be classified as harassment depending on the words said, time and its circumstances.
So it is possible that you are not intending to threaten someone over the phone, but if your calls are annoying the receiver, they can ask their mobile company or the police to investigate and trace the prank call.
What can I do if I receive a prank call?
Hang up immediately. If you keep getting prank calls, you can make a complaint to the local police. They can then investigate, and, if necessary, prosecute the person who made the call.
You can also contact your phone company to help. For example, Telstra has a special call centre to help customers who are receiving unwanted phone calls. However your phone company is not obliged to disclose the information of the person calling you, unless asked by the police.
If you receive a phone call, you should not:
- Find out yourself who the caller is – this may be dangerous
- Threaten the caller
- Pretend you are a police officer when receiving the phone call (Impersonating a police officer)
If you threaten the caller or pretend to be a police officer, this may result in you being investigated for a criminal offence.
Stalking by prank calls
Unwanted contact through any technological means that happens more than once and causes concern or fear may constitute stalking. This means that repeated prank calls may be considered stalking. The penalties for stalking by prank calls can be very serious.
Bullying by prank calls
Repeated prank calls may also be bullying. If the prank calls becomes harassment, or illegal threats, then it becomes a form of bullying. Please refer to our Bullying section.

What you needCopper Jewelry wire
Approx 30 old buttons
Start by taking your length of wire around 1 yard and creating a knot or bend at one end (so your buttons don't slip off) then begin threading your buttons onto the wire by taking the wire through the button holes as if it was a needle and thread.
Keep doing this – adding each button as you go. Position the buttons flat by pushing and shaping the wire so that the buttons each sit flat.
Keep doing this until you reach your desired length. You can add a small jewelry clasp or simply create a necklace that will slip over the head by twisting the two ends of wire together.
This method is great for kids!

Crabs Live All Over The World
What Eats A Crab? Photo:Gordon E. Robertson
What eats crabs?
What do crabs eat?
Crabs live all over the world. Some kinds, or species, live in salt water, others live in fresh water. Some even spend all their time on dry land.
Most crabs have many natural enemies, or predators. Birds attack smaller crabs, sometimes carrying them high into the air and then dropping them on boulders to crack their shells.
Fish with powerful, shell-crunching jaws also eat crabs.
Many kinds of mammals, from seals to raccoons, also look forward to a crab dinner.
What does a crab eat? Crabs eat small bits of plant and animal material that they find in the water and along the shoreline.

The development of Competitiveness - A theoretical approach in a European context
The aim of this paper is to theoretically establish a framework for the basics of international trade between countries creating competitiveness. Since the environment in which trade takes place is changeable so is the concept of competitiveness. It is therefore argued in the paper that in order to understand the underlying factors of competitiveness one have to understand the environment in which trade takes place in. Today the concept of competitiveness will therefore be better understood by employing an industrial perspective. This approach can answer questions, which national aggregate estimates cannot. The question asked in the paper is; which industries in Europe, based on the assumptions of international trade theories is competitive? The European industries that came out as competitive were the one using high-skilled labor and produced or used ICT intensively in their production. The question also provided some answers to the always up-do-day wonder namely, in which direction European competitiveness is heading.

Whale watching
The tropical climate of Costa Rica and its warm waters are ideal for these marine mammals that enjoy specific areas along the coast.
The best place to observe whales in Costa Rica is on the Pacific Coast, where humpback whales migrate between July and November and then again between December and March.
The Osa Peninsula is visited by humpback whales that migrate from both the northern and southern hemispheres, meaning that whale populations are concentrated more here than in any other part of the country. Additionally, this large group of whales remains close to the peninsula for a long time, giving Costa Rica one of the longest whale watching seasons in the world.

Understanding the factors affecting the survival of patients undergoing hemodialysis is the mainstay of care in this population. The present study aims at finding these features using novel cure models that discover factors important in both long term and short-term survival of patients undergoing HD.
Data were retrospectively collected from the database of Shiraz University of Medical Sciences Special Diseases Administration including patients of 34 HD centers during 2011 to 2015. The primary outcome was death. Considering people with no death event as cured, the rest of the patients considered as uncured. To evaluate the factors affecting mortality, we used a mixture cure model (MCM) that model the long-term and short-term survival of patients separately.
Of 506 patients, 68.75% of women and 75.0% of men were long-term survivors. The mean (± SD) age of the patients was 57.5 (± 16.5) years and the empirical value of the cure rate was 72.9%. Sex, age, and Kt/Vurea were recognized as important factors in the long-term survival. In other words, lower age, male sex, and Kt/ Vurea ≥ 1.2 significantly increased the odds of being cured. The factors effective in short-term survival were mean corpuscular hemoglobin concentration (MCHC) and serum hemoglobin. The serum hemoglobin between 11 and 12.5 and a high MCHC decreased the risk of death.
Using cure model survival analysis, it was found that factors affecting the proportion of the patients with long-term survival might be different from those affecting short-term survival.

Young Adults from 14 Caribbean Countries Gather Material for Environmental Book
ROSEAU, Dominica Young adults from 14 Caribbean countries recently finished gathering material for a book on the environment they hope will get more young people involved in protection efforts.
The book will highlight environmental issues facing the region and provide examples of how younger generations can influence government policies, said organizer Frederick Arnett.
"Our purpose is to bring about a change in the mentality and attitude about the environment" among young adults, Arnett said.
The material was gathered from 30 environmental activists, ages 18 to 25, over the past week in Roseau, Arnett said.
Funding to publish the book will come from the Barbados-based Caribbean Youth Environment Network and United National Environmental Program, though no publication date has been set.
The program plans to sell copies across the Caribbean.

What is muram?
Disintegrated rocks are termed as muram.
Muram flooring are constructed mostly in villages and have the same merits as that of mud flooring. First of all, the subgrade is prepared up to 6″ thick and then a thick layer of muram is laid above the subgrade. Then 1″ thick layer of powder muram is spreaded over the previously laid muram layer and water is sprinkled thoroughly over the surface. The surface is rammed and then saturated with water so that a thin layer is formed on the top of the rammed surface. Then the surface is trampled well till the cream of muram rises to the top. The surface is allowed in this state for about 20-24 hrs and then it is rammed again with wooden rammers called thapies for about two to three days. The dry hard surface thus formed is then smeared with a thick coat of cow dung and rammed once again for two days in the morning. Finally the surface is finished with a cement cow-dung plaster 1:4 (1 cement : 4 cow dung). To maintain muram flooring in good condition, it is given a wash of cement cow-dung plaster once a week and the surface is wiped clean immediately.
Advantages of Muram Flooring:
- Muram flooring are cheap and the method of construction is easy.
- It is suitable for all climatic conditions
- It has long life when it is properly maintained
- It provides smooth, hard and less permeable surafce.
- The maintenance of this flooring is quite difficult. Because, the surface it has to be given cement cow-dung wash once or twice a week.

It's snow problem for hardy Alpacas
Buy this photo » Rocky the Alpaca
THE snow has meant more rations and warmer bedding for most of the animals at Millet's Farm Centre near Abingdon.
But Alpacas Rocky and Eismann have also been showing off the skills that make them some of the world's hardiest animals.
While the county shivers in freezing temperatures, Rocky and Eismann have been keeping warm thanks to their thick Peruvian fur, or fibre.
And they've also been using their heads – and their noses and tongues – to reach the tasty grass buried beneath the snow.
Millet's outdoor animal keeper, Malcolm Skinner, 46, explained: "Alpacas are used to extremely cold temperatures, originating as they do from the Andes mountains.
"While most of the other animals here have been eating extra hay, Rocky and Eismann prefer to scratch and nuzzle, using their toes to burrow into the snow, before searching the green grass out with their mouths and long tongues."
Alpacas come from the highest regions of the Andes mountains in Peru and are bred mostly for their fibre – a thick, silky fur which not only keeps them warm, but is also used for making very soft, knitted and woven items.
Mr Skinner continued: "We have been giving the ponies, guinea pigs, sheep, goats and pigs extra warm bedding and more food than usual, but Rocky and Eismann are undeterred by this weather.
"People love seeing their woolly coats and although they fight a bit amongst themselves and are not that fond of dogs, they are pretty friendly animals."

Luctor et Emergo" is a heart-warming, true story about the author's parents and their loss of hearing at a young age. The Latin phrase "Luctor et Emergo" means "I struggle and overcome". This simple Latin expression was often quoted by the author's father, Horace E. Dean, and it sums up the theme of the book.
People can overcome the most difficult of circumstances in life if they will persevere. The book details the myriad of challenges the author's deaf parents faced throughout life and their persistent determination to overcome their disability and disappointments with their faith in God. This uplifting and sometimes humorous story of the indomitable nature of the human spirit will encourage young and old alike, especially those persons who are struggling with life's challenges.

MCC investments in roads cut across several sectors. In transportation projects, roads rehabilitation and construction primarily aim to lower transport costs by reducing travel time and vehicle operating costs; improve access to public basic services such as health and education, particularly for the rural poor; and facilitate international and regional trade. In agriculture projects, roads primarily aim to link producers to markets for their goods and to inputs for their production year round. In some cases, roads are a part of irrigation projects to provide access to, from, and within irrigated areas.
