Shadow properties in Entity framework core (EF 7)
Entity framework core introduces new feature known as shadow properties. Shadow properties are do not part of entity class, but treated as part of it. The value and state of these properties is maintained purely in the Change Tracker API. These properties can participate in all database operations, but should not be exposed via entity class to the rest of the application.
shadow properties
The main advantages of shadow properties are you can access it without declaring it as part of domain model and It allows developers to define properties in class which doesn't have source code for.
Let's take example of Employee, In database Employee table have five properties EmpoyeeId, FirstName, LastName, Age and CreatedDate. CreatedDate is not exposed and should be define as Shadow properties.
public class Employee
{
 public int EmployeeId { get; set; }
 public string FirstName { get; set; }
 public string LastName { get; set; }
 public int Age { get; set; }
}
Currently, Shadow properties can not be created with data annotations. You can use the Fluent API to configure shadow properties. Shadow properties are defined by overriding OnModelCreating event in DbContext class.
Here is an example of attaching a DateTime property called CreatedDate to the Employee entity. CreatedDate properties state will be manage by change tracker API by it self.
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
 modelBuilder.Entity<Employee>().Property<DateTime>("CreatedDate");
}
As Change tracker APIs are responsible to manage State of Shadow properties, Get and Set operations will be perform by Change tracker APIs. We can modify the value of shadow property.
context.Entry(employee).Property("CreatedDate").CurrentValue = DateTime.Now;
Shadow properties can be referenced in LINQ queries via the EF.Property static method. For example, the following code can be used to retrieve employee list order by created date.
var employees = context.Employee
 .OrderBy(b => EF.Property<DateTime>(b, "CreatedDate"));
On OnModelCreating event execution, If the name supplied to the Property method matches the name of an existing property (a shadow property or one defined on the entity class), then the code will configure that existing property rather than introducing a new shadow property.

text: Lambertville is a City in Hunterdon County, New Jersey, United States. As of the United States 2000 Census, the city population was 3,868. Lambertville was originally incorporated as a town by an Act of the New Jersey Legislature on March 1, 1849, from portions of West Amwell Township. The area was reincorporated as a city on March 26, 1872. Lambertville is located on the Delaware River in the southwestern portion of Hunterdon County. During the 1700s, the City was named after various operators of ferries across the river to Pennsylvania, ultimately becoming known as Coryell's Ferry, after Emanuel Coryell who owned the Ferry. Coryell's Ferry was the western terminus of the New Jersey portion of the York Road (which is now known as U.S. Highway 202) connecting New York City and Philadelphia. The City was named Lambertville in 1814 when the post office was established, in honor of John Lambert, a local resident, who had served as United States Senator and Acting Governor of New Jersey.

Wilhelmus Zakaria Johannes (1895 – September 4, 1952) was an Indonesian radiology doctor. Johannes was the first Indonesian medical doctor who learned radiology in the CBZ (Civil Hospital) in Batavia and then became an expert in Rontgen technology and had contributed a lot to the development of medical studies in Indonesia. The Indonesian government honored WZ Johannes as a National Hero of Indonesia and named a general hospital in Kupang, East Nusa Tenggara after him. As a tribute, the name Wilhelmus Zakaria Johannes was used on an Indonesian Navy ship, the KRI Wilhelmus Zakarias Yohannes. Johannes died in 1952 and was buried at the Jati Petamburan Cemetery in Central Jakarta.
WZ Johannes was the cousin of Professor Herman Johannes, an Indonesian professor who was the Rector of Gadjah Mada University and father of Helmi Johannes, a newscaster and executive producer for VOA Indonesian television in Washington DC.

¨ is injective if and only if different inputs give different outputs.
¨ is injective if and only if "different elements of A go to different elements of B."
¨ It is the whole function that is or is not injective.
¨ The articles about most of the example functions state whether they are injective or not. Checking each of these functions to see why it is or is not injective is an excellent way to get a feel for the concept of injectivity.
¨ The doubling function is injective on the real numbers and in fact on the complex numbers. Doubling different numbers gives different numbers.
¨ The squaring function is not injective, because for example. Squaring different numbers might give you the same number.
¨ The cubing function on the reals is injective. It is not injective on the complex numbers, because for example
¨ See Wikipedia for more examples and more discussion.
No information loss
An injective function loses no information. If you have an output from the function, you know it came from exactly one input.
¨ If you got 8 when you cubed a real number, the real number had to be 2. The cubing function is injective on the reals. But if you got 8 when you cubed a complex number, the complex number could be any of three numbers (see above); the cubing function is not injective on the complex numbers.
¨ If you got 4 when you squared something, the something could have been either 2 or 2: You lost some information about the input, namely its sign in this case. The squaring function is not injective.
¨ If you get as an output from the sine blur function, it could have come from any one of an infinite number of inputs. The sin blur function is ridiculously noninjective.
Embeds as a substructure
Some functions preserve some structure. For example, multiplying integers by 2 preserves addition. In other words, if you let be defined by, then (write it out, don't just believe me!). This makes it a group homomorphism. Because multiplying by 2 is injective, this says that the substructure of the group of integers with addition as operation that consists of the even integers is a copy of the group of integers itself.
Horizontal line crosses the graph only once at most
Let be a real continuous function. Then F is injective if no horizontal line cuts it twice. This is a useful way of thinking about injective continuous functions, but it doesn't work with arbitrary functions.
a) This is a plot of part of (which is injective) with some horizontal lines
b) On the other hand, is not injective. Note that some horizontal lines cut it more than once, but others cut it only once.
c) Horizontal lines don't have to cut a function at all. This is part of. Horizontal lines below zero don't cut its graph because 0 is its minimum. There are horizontal lines that cut it twice, so it is not injective.
A function is surjective if and only if
¨ is surjective if and only if the image of F is the same as the codomain B.
¨ is surjective if and only if "every element of B comes from an element of A."
¨ Let be the squaring function, so for every real number x. Then F is not surjective, since for any negative number b, there is no real number a such that F(a) = b. (You can't solve, for example).
¨ But if you define (where denotes the set of nonnegative reals) by, then G is surjective. As you can see, whether a function is surjective or not depends on the codomain you specify for it. Note that "G is surjective" says exactly that every nonnegative real number has a square root.
Another way of saying that is surjective is to say, "F is surjective onto B", or simply, "F is onto B". Saying it this way does not depend on whether you use the loose or strict definition for functions.
A function is surjective if every horizontal line crosses its graph (one or more times). Check out the graphs (a) through (c) above: and are surjective onto, but is not surjective onto. H is surjective onto the set of nonnegative real numbers.

Indian Head Nickel 385 Trial Proof by Andy Warhol
Title: Indian Head Nickel 385 Trial Proof
Medium: Screenprint on Lenox Museum Board.
Size: 36″ x 36″
Andy Warhol created Indian Head Nickel 385 in 1986 for his Cowboys and Indians portfolio. Warhol was fascinated by celebrity myths and the ways in which stories are represented by the media. This allure led Warhol to create his Cowboys and Indians portfolio as a commentary about the myth of the American West. He used recognizable images like this one of Indian Head Nickel that are representative the popular yet ahistorical version of Native American culture. Warhol removed this native imagery from its original context and interspersed it with images of romanticized American heroes. Indian Head Nickel is an example of Warhol's fascination with the way media and society interpret histories and misrepresent the history of the American west. This particular print is a unique color combination.

NAME
 lpc -- line printer control program
SYNOPSIS
 lpc [command [argument ...]]
DESCRIPTION
 The lpc utility is used by the system administrator to control the opera-
 tion of the line printer system. For each line printer configured in
 /etc/printcap, lpc may be used to:
 +o disable or enable a printer,
 +o disable or enable a printer's spooling queue,
 +o rearrange the order of jobs in a spooling queue,
 +o find the status of printers, and their associated spooling
 queues and printer daemons,
 +o change the status message for printer queues (the status mes-
 sage may be seen by users as part of the output of the lpq(1)
 utility).
 Without any arguments, lpc will prompt for commands from the standard
 input. If arguments are supplied, lpc interprets the first argument as a
 command and the remaining arguments as parameters to the command. The
 standard input may be redirected causing lpc to read commands from file.
 Commands may be abbreviated; the following is the list of recognized com-
 mands.
 ? [command ...]
 help [command ...]
 Print a short description of each command specified in the argu-
 ment list, or, if no argument is given, a list of the recognized
 commands.
 abort {all | printer}
 Terminate an active spooling daemon on the local host immediately
 and then disable printing (preventing new daemons from being
 started by lpr(1)) for the specified printers.
 bottomq printer [jobspec ...]
 Take the specified jobs in the order specified and move them to
 the bottom of the printer queue. Each jobspec can match multiple
 print jobs. The full description of a jobspec is given below.
 clean {all | printer}
 Remove any temporary files, data files, and control files that
 cannot be printed (i.e., do not form a complete printer job) from
 the specified printer queue(s) on the local machine. This com-
 mand will also look for core files in spool directory for each
 printer queue, and list any that are found. It will not remove
 any core files. See also the tclean command.
 disable {all | printer}
 Turn the specified printer queues off. This prevents new printer
 jobs from being entered into the queue by lpr(1).
 down {all | printer ...} -msg message ...
 down {all | printer} message ...
 Turn the specified printer queue off, disable printing and put
 message in the printer status file. When specifying more than
 one printer queue, the -msg argument is required to separate the
 list of printers from the text that will be the new status mes-
 sage. The message does not need to be quoted, the remaining
 arguments are treated like echo(1). This is normally used to
 take a printer down, and let other users find out why it is down
 (the lpq(1) utility will indicate that the printer is down and
 will print the status message).
 enable {all | printer}
 Enable spooling on the local queue for the listed printers. This
 will allow lpr(1) to put new jobs in the spool queue.
 exit
 quit Exit from lpc.
 restart {all | printer}
 Attempt to start a new printer daemon. This is useful when some
 abnormal condition causes the daemon to die unexpectedly, leaving
 jobs in the queue. lpq(1) will report that there is no daemon
 present when this condition occurs. If the user is the super-
 user, try to abort the current daemon first (i.e., kill and
 restart a stuck daemon).
 setstatus {all | printer} -msg message ...
 Set the status message for the specified printers. The -msg
 argument is required to separate the list of printers from the
 text that will be the new status message. This is normally used
 to change the status message when the printer queue is no longer
 active after printing has been disabled, and you want to change
 what users will see in the output of the lpq(1) utility.
 start {all | printer}
 Enable printing and start a spooling daemon for the listed print-
 ers.
 status {all | printer}
 Display the status of daemons and queues on the local machine.
 stop {all | printer}
 Stop a spooling daemon after the current job completes and dis-
 able printing.
 tclean {all | printer}
 This will do a test-run of the clean command. All the same
 checking is done, but the command will only print out messages
 saying what a similar clean command would do if the user typed it
 in. It will not remove any files. Note that the clean command
 is a privileged command, while the tclean command is not
 restricted.
 topq printer [jobspec ...]
 Take the specified jobs in the order specified and move them to
 the top of the printer queue. Each jobspec can match multiple
 print jobs. The full description of a jobspec is given below.
 up {all | printer}
 Enable everything and start a new printer daemon. Undoes the
 effects of down.
 Commands such as topq and bottomq can take one or more jobspec to specify
 which jobs the command should operate on. A jobspec can be:
 +o a single job number, which will match all jobs in the printer's queue
 which have the same job number. Eg: 17,
 +o a range of job numbers, which will match all jobs with a number
 between the starting and ending job numbers, inclusive. Eg: 21-32,
 +o a specific userid, which will match all jobs which were sent by that
 user. Eg: jones,
 +o a host name, when prefixed by an '@', which will match all jobs in
 the queue which were sent from the given host. Eg: @freebsd.org,
 +o a job range and a userid, separated by a ':', which will match all
 jobs which both match the job range and were sent by the specified
 user. Eg: jones:17 or 21-32:jones,
 +o a job range and/or a userid, followed by a host name, which will
 match all jobs which match all the specified criteria. Eg:
 _EMAIL_ or _EMAIL_ or jones:_EMAIL_.
 The values for userid and host name can also include pattern-matching
 characters, similar to the pattern matching done for filenames in most
 command shells. Note that if you enter a topq or bottomq command as
 parameters on the initial lpc command, then the shell will expand any
 pattern-matching characters that it can (based on what files in finds in
 the current directory) before lpc processes the command. In that case,
 any parameters which include pattern-matching characters should be
 enclosed in quotes, so that the shell will not try to expand them.
FILES
 /etc/printcap printer description file
 /var/spool/* spool directories
 /var/spool/*/lock lock file for queue control
DIAGNOSTICS
 ?Ambiguous command abbreviation matches more than one command
 ?Invalid command no match was found

Suppose $F$ is a field s.t $\left|F\right|=q$. Take $p$ to be some prime. How many monic irreducible polynomials of degree $p$ can exist over $F$?
share|improve this question
What have you tried? (Think about subextensions of $\mathbb{F}_{q^p}$ over $\mathbb{F}_q$.) – Qiaochu Yuan May 23 '11 at 9:31
_USER_: Thanks, got the idea and found the answer... will write it down here soon! – IBS May 23 '11 at 13:25

The number of such polynomials is exactly $\displaystyle \frac{q^{p}-q}{p}$ and this is the proof:
The two main facts which we use (and which I will not prove here) are that $\mathbb{F}_{q^{p}}$ is the splitting field of the polynomial $g\left(x\right)=x^{q^{p}}-x$,
and that every monic irreducible polynomial of degree $p$ divides $g$.
Now: $\left|\mathbb{F}_{q^{p}}:\mathbb{F}_{q}\right|=p$ and therefore there could be no sub-extensions. Therefore, every irreducible polynomial that divides $g$ must be of degree $p$ or 1. Since each linear polynomial over $\mathbb{F}_{q}$ divides $g$ (since for each $a\in \mathbb{F}_{q}$, $g(a)=0$), and from the fact that $g$ has distinct roots, we have exactly $q$ different linear polynomials that divide $g$.
Multiplying all the irreducible monic polynomials that divide $g$ will give us $g$, and therefore summing up their degrees will give us $q^{p}$.
So, if we denote the number of monic irreducible polynomials of degree $p$ by $k$ (which is the number we want), we get that $kp+q=q^{p}$, i.e $\displaystyle k=\frac{q^{p}-q}{p}$.

Nice answer and question as well! +1 for both... Btw, you can accept your own answers? – Kugelblitz Mar 10 at 13:40
the number of monic irreducible polynomials of degree $n$ over the ﬁnite ﬁeld $\mathbb{F}_{q}$ is given by Gauss's formula $$\frac{1}{n}\sum\limits_{d \mid n} \ \mu(n/d) \cdot q^{d}$$
For a complete proof : Please refer
 - Abstract Algebra: Dummit and Foote, Chapter 14, Galois theory, Pages $567-568$.
 - You might also want to see this paper, which actually presents a new idea of counting irreducible polynomials using Inclusion - Exclusion Principle. Link: _URL_
share|improve this answer
Just knowing the answer is not useful to anybody. I also suspect that this is a homework problem based on the condition on degrees, so please don't give answers like that. – Qiaochu Yuan May 23 '11 at 9:40
_USER_: Ok... – user9413 May 23 '11 at 11:20
_USER_: the proof presented in that paper is not new; it is equivalent to the classical proof by Mobius inversion. Inclusion-exclusion is a special case of Mobius inversion on a poset. – Qiaochu Yuan May 23 '11 at 11:24
_USER_: i hope you don't mind, but Qiaochu is right and this was a homework qeustion about the extension $\mathbb{F}_{q^{p}}\geq\mathbb{F}_{q}$. I actually used Quaochu's comment to find the answer myself... appreciate the help. – IBS May 23 '11 at 13:24
_USER_: Hey no problem. I never thought about it. Anyhow good that you got the answer. That is important. – user9413 May 23 '11 at 13:25

1+1+1 – A Simple Way to Read the Bible (Download Powerpoint)
Can you think of some famous numbers?
999 – the phone number you ring in an emergency.
118 118 – the phone number you ring to get information.
1966 – the year that England won the World Cup.
43252003274489856000 – the number of possible positions on a Rubik's cube.
I want to introduce you to another number that should be famous. This number describes a simple and easy way to read the Bible.
The number is 111 or 1+1+1.
Here's how it works:
1 – Book of the Bible a month.
1- Chapter to read a day – doing this will mean for some books of the Bible, you'll get to know them really well as you'll read through them more than once in a month.
1 – Verse to think about – the final step is from the chapter you've read take one verse and spend the rest of the day thinking about it and praying it for yourself, your family, church and non-Christians. Alternatively you could take from the chapter one 'thought to make your heart sing'.
1 book a month, 1 chapter a day, 1 verse to think about. 1+1+1 – a simple way to read the Bible.
[This simple way of reading the Bible also works well with The Big Read that we're doing at Banstead Community Church].

[antlr-interest] What do. (period) and Tokens mean in tree grammars?
Harald M. Müller
harald_m_mueller at gmx.de
Sat Dec 29 14:16:13 PST 2007
Sorry that I ask - but I did not find it on the Wiki and not in the ANTLR
book: What do. and Tokens mean in tree grammars?
AFAIK,. means "any complete subtree." - although this seems not to work in
some current builds, if I understood some email of yesterday correctly?
Question number two:
Does a single Token also match a complete tree with this token at the root,
or only a "childless tree" (i.e. the token as a tree node alone)?
Question number three:
What sort of lookahead is used over.? For example, would the following
work - assume here that the subtrees can be arbitrarily large subconditions
(as is usual in expression trees):
condition : ^(AND. ^(NOT.)) ->...rewrite1...
| ^(AND..) ->...rewrite2...
The intention of this is to rewrite an AND tree which has as second child a
tree with a NOT root to rewrite1; whereas all other trees are supposed to be
rewritten as rewrite2.
If ANTLR tree parsing works the way I assume it - namely the whole tree is
flattened to a node sequence, on which "one-dimensional" parsing techniques
(even LL(*)) are applied, then the NOT will be "too far" away even for an
LL(*) analysis, because there will be recursively nested expressions on the
way between the AND and the NOT. However, if ANTLR goes for real
"two-dimensional" parsing, or does some lookahead over arbitrarily large
subtrees (to the readily available "later" children!) - which I would call
"1.5-dimensional lookahead computation/parsing", then the above two patterns
could be disambiguated.

A Quick Guide to Running X11 Apps on WSL2
In WSL1, all you had to do was install an X server and you could run X11 apps normally. But in WSL2, it gets a bit harder. It runs in a VM instead of being run as a compatibility layer.
Starting VcXsrv
First, start up VcXsrv (or whatever X server you use). Make sure to turn off access control to allow WSL to access it without being blocked, and make sure it runs on 0.0.0.0 to ensure that it's possible to access it outside of the current computer.
Setting environment variables
Since WSL is running in a VM, it can't directly connect to localhost; it has to connect to the IP address.
Here is a script (albeit lengthy) to set the $DISPLAY variable by grabbing the IP address by invoking powershell, cutting off the last character (a carriage return), and appending :0.0 to the IP:
export DISPLAY=$(/mnt/c/Windows/System32/WindowsPowershell/v1.0/powershell.exe -Command '(Get-NetIPAddress -AddressFamily IPv4 | Where-Object {$_.AddressState -eq "Preferred" -and ($_.InterfaceAlias -eq "Wi-Fi" -or $_.InterfaceAlias -eq "Ethernet")}).IPAddress' | sed 's/.$//'):0.0
We also need to make sure that OpenGL tells the X server to draw graphics and doesn't try to directly access the hardware.
export LIBGL_ALWAYS_INDIRECT=1
Here is a Github Gist containing a shell script that does this for you.
Running apps
There are no special instructions for running apps, just run them like you would in a regular Linux system.

Creating a Problem
There are three ways to create a problem in the Neural Networks Applet.
- Load a Sample Graph (with data)
This is the way to load a prebuilt neural network. You can load from a set of sample problems, or load from a URL. Take note
that this expects a file with both data and graph information. This will return an error if there is
On the menu bar, select File->Load A Sample Graph and Data. A dialog will pop up with a choice of sample problems. Choose one.
On the menu bar, select File->Load Graph and Data From URL. Type in the URL of the neural network file, and click load.
- Load Data
This is the way to load a comma-delimited data file and create a network to solve it. You can load from a set of sample
problems, or load from a URL. This will split the data equally into the training and test sets.
On the menu bar, select File->Load Sample Data. A dialog will pop up with a choice of sample problems.
On the menu bar, select File->Load Data From URL. Type in the URL of the data file, and click load.
- Create the Neural Net and the example set manually.
Click the Create mode tab to display the Create panel. Select the Create Node button and click on the canvas to
create at least two nodes. Then, select the Create Edge button and connect the two nodes by clicking on the parent
node and then clicking on the child node. The applet will automatically determine which nodes are input, output, or hidden.
It is required that the neural net be completely connected - thus an input node has to be connected to all the nodes of
its children's layer (whether hidden or output).
For the neural net to learn, you must give it training examples. To add training examples, click the View/Edit Examples button to open the Edit Examples dialog box. Click the
'Add New' button
on the dialog, and the applet will query you for one example. Add an example.
Solving A Problem
Click the Solve mode tab to go to Solve mode. Click Initialize Parameters to reset the learning of the applet. There
are three ways to perform backpropagation in the Neural Networks applet.
- Step through the process one step at a time by clicking the Step button.
- Step through the process 50 steps at a time by clicking the Step 50X button.
- Allow the applet to solve to a preset minimum error (.1 by default) by clicking the Step To Target Error button.
When performing multiple steps, you can stop stepping by clicking the Stop button
To show the error plot, click the Show Plot button. To get an output given a set of inputs, click the Calculate
Output button and enter the desired inputs. The inputs given are NOT added to the test or training sets. Also, these
inputs do not affect the learning of the network in any way.

Do you think the following is a good approach?
Example for face encodings:
- Create an item (in table item).
- Use column item.app=faces and item.title=encoding to find (all of them) later on.
- Store a face encoding (content of a row in faces_encoding) in column item.obj
- Store the hash of the item in the encoding (faces_encoding.file_hash)
- Use item.sync_an_item($channel_id,$item_id)
- Before the channels clone starts a face recognition (it is always only triggered manually by the user via browser)
- Select all items using item.app=faces AND item.title=encoding
- Read the encodings from the items and write the encodings if new or changed
Depending on how it goes I would change it, e.g.
- Sync an image with all encodings instead each encoding separately.
- Of course I have store the file (image) hash in each encoding.
Do you can imagine a completely different way of syncing the data?
Is attach more appropriate or iconfig or...?
Once it works for ZAP I would port it to Hubzilla.
Many thanks in advance.

How to have sex several times a day! Having a second erection after an orgasm
How to have sex several times a day! Having a second erection after an orgasm Posted on 10 October 2018Leave a comment
Many men feel frustrated at not being able to satisfy their partner because of the difference in the time it takes a man to enjoy and that of a woman. Often, to make a woman enjoy, men end up with their fingers or leave their partner to fend for themselves. Yet all men would like to assure and say that they are able to have a new erection and put the cover back.
If men are unable to have a second erection after cumming, it is because of the refractory period. It is this phenomenon that happens just after having enjoyed. Man produces hormones of well-being and satisfaction, which prevent him from being aroused again and to get a boner directly. All this is also a question of testosterone. We tell you everything!
How long does it take to get a new erection?
Unfortunately, answering this question is difficult because you know it better than us. It depends on everyone, and age. As the refractory period depends on your hormones and your testosterone, this period of time increases with age, since hormonal imbalance occurs with age. A 50-year-old man produces testosterone less quickly than a 20-year-old man.
For example, in a young man of 20 years, the refractory period is 2 to 15 minutes, while for a man of 40, he must wait 1 to 2 hours before having an erection again after doing the love. And when you're 70 years old, you have to wait 24 hours before having sex again. That's why mechanically, without viagra, without any help, a man of 70 years without erection problems makes maximum love 7 times a week.
What is the refractory period?
The refractory period in physiology is the moment immediately preceding the activity of a nerve or a muscle. After intense activity, the muscle ignores any stimulation, then after a while, we start a second phase, which is the recovery phase during which the muscle regains sensitivity but is still weak.
For sex, it's pretty much the same thing. Except that the mechanism is different. The refractory period refers to the length of time between two periods of sexual activity. Put another way and simply, it's the time it takes for your penis to get hard again.
Is it impossible to get hard again after an orgasm?
Knowing why we lose our erection after sex is the same as asking ourselves what causes this refractory period. The main causes are two hormones: prolactin and oxytocin. Prolactin is a hormone that like testosterone plays a role on the libido. This hormone is produced in quantity when reaching orgasm. Its role is to provide a feeling of well-being and a bliss. We can thank that hormone! Except that our body is so tired, that it kills the effect of arousal that causes testosterone. Oxytocin is a neuropeptide that is a bit like the magic wand that makes you fall in love. It also gives a feeling of confidence, rest, zenitude and love.
We do not say that love is bad and that to be sexually active you must not be in love. Besides, love is not only due to these two hormones, but the high presence of these hormones after orgasm induces the body to feel good. You are no longer looking for something else. Simply, you are not arroused.
How to decrease the refractory period?
The basic answer is very simple: you have to increase your testosterone level. The longer answer is also to have a much healthier lifestyle: quit smoking, drinking, playing sports, eating balance.
 - Testosterone cure
For the testosterone level, fortunately, there are solutions. Just take a course of testosterone supplements. These natural capsules are studied to increase the rate of testosterone, which obviously allows to band faster. This is why a teenager or a young man has a much shorter rest period. This is because it is at its peak of testosterone production. Unfortunately, the testosterone level decreases with age.
produit pour avoir plus de testostérone⇒ We advise you to start a TestRX cure!
It also contains many vitamins such as B6 or vitamin D. But that's not all! You will understand with the following point why it is advisable to buy this product.
 - Cure of vitamins and dietary supplements
Again, for vitamins there is a solution. Zinc is very good for sexual performance, especially to increase sperm production. Some vitamins help maintain muscle shape and tone.
⇒ We told you to buy TestRX because it is twice a solution to the problem of testosterone.
In addition to having all the natural components to increase testosterone, it includes many vitamins and dietary supplements. There is magnesium, zinc, D-aspartic acid, fenugreek, vitamin K2, B6 and D.
 - Improve your lifestyle
For the other points, there is no cure, it's up to you to make an effort. Eating fat is bad for the body and being overweight has destructive effects on sexuality. Eating too much sugar can have inhibitory effects on the excitement. The cigarette is very bad for sexual performance. If you are used to watching porn frequently, reduce the dose a little. Porn has a negative effect on long-term sexual arousal.
Reducing stress is obviously very important. Everyone knows that when you're stressed you can have trouble to have a boner. Try to find a way to reduce stress, relieve tension, think of something else.
Eat products rich in nitric oxide (NO). These are nitrates that are found in a series of foods and that promote the influx of blood. Since the penis is full of blood and erection is possible because of cavernous bodies that are filling with blood, it is wise to find a way to improve the flow of blood. Citrulline, arginine and nitrates promote the production of nitric oxide. The rich foods are watermelon, rhubarb, beets, spinach and celery.
 - Avoid too much tenderness
As we have seen, we already produce enough hormones that make us feel good and soothed. In fact, everything is done so that we look at each other with love and sweetness. Unfortunately, this behavior also indicates to our body that it has had its dose of sex. So to avoid falling into too much romance that would cut the carnal desire for sex, do your best to stay in an atmosphere more sexual than romantic.
For example, do not stay in bed doing cute hugs. Do not get into burning statements. Jump from bed, try to think of things that excite you. See your partner as a fantasy and not as the loving person who makes your heart beat. Yes … it's easier said than done!

Integration of entrepreneurship into educational curriculum will reduce the high rate of unemployment in Nigeria
- 1 Post
- 0 Comments
It is self evident that education is the key that unlocked the inner mind towards creativity. There are geniuses no doubt, but remember that a sage has defined genius as 99 per cent perspiration and one per cent inspiration. the developed world has long recognised the symbiotic relationship between the 'Gown' and 'Town', that's why a sizable portion of their GDP goes into research.
The bottom line is that if integration of entrepreneurship into our educational curriculum is properly planned and executed as a genuine collaboration between the Institutions and the Industries, the idea will not only help solve our unemployment problems, but equally assist in laying a solid foundation for the nation's industrial breakthrough.
Entrepreneurship study in Institution is beyond class work.if our institutions do not know how to do it,they should engage expert from outside. It's more of apprenticeship than course work.
This is a critical issue that higher institutions of learning in the developing world have to give thoughts. We will go nowhere until we learn to Do and not just to consume.

SummerMath: Research into Practice.
An experience in attempting to transform research into practice is described, with questions raised about the relationship between research and practice. The author begins by describing the two research traditions which exerted the most force on the design of the program. How the philosophy and findings of those traditions were interpreted and implemented is discussed as the SummerMath program is described. This was a six-week program for high school students, to encourage young women to gain an understanding of mathematics in order to increase their participation in mathematics and mathematics-related fields, as well as to implement the findings of research to improve learning. Sections focus on research into practice, research on mathematics learning, curriculum, instruction, women and mathematics, and evaluation. Results of the implementation and new research questions are each presented. (MNS)

Paul and Julie Weissend bought the Richmond and Chesapeake Bay Railway Car Barn planning to use historic credits and green technology to breathe new life into the 101-year-old Richmond building.
The structure was built to service passenger cars on an electric-railway that ran from Richmond to Ashland from 1907 to 1938. The Weissends are turning it into offices for two companies, Dovetail Construction and D-Tail Plumbing, which they previously managed from their home. "To us, it's really the ultimate in recycling and being green because you're reusing something that was already developed," says Julie Weissend.
The project presented the Weissends with the challenge of preserving the building's historic integrity while making it energy efficient and sustainable.
Their solution? Create a building within a building. The car barn's exterior largely will retain its original design (except for a wall of energy-efficient windows). But the interior and exterior will incorporate elements that meet the certification criteria of the Leadership in Energy and Environmental Design (LEED) Green Building Rating System.
The project, scheduled to be completed at the end of this year, will feature highly efficient heating and cooling systems, rainwater catchment systems, a permeable parking lot that reduces toxic runoff and bike racks for employees who want to forgo driving their cars. "We're going through every aspect of the LEED criteria and at every selection point trying to beat what typically happens in terms of wasted energy," Julie Weissend says.


Mining project behind Greenland political upheaval
In snap elections April 6, Greenland's indigenous-led left-environmentalist party Inuit Ataqatigiit (Community of the People) won 37% of the vote, overtaking the longtime incumbents, the social-democratic Siumut (Forward) party. At the center of the race was a contentious mining project that Inuit Ataqatigiit aggressively campaigned against. The Kvanefjeld rare-earth mineral project, near Narsaq in Greenland's south, has divided the territory's political system for more than a decade. Greenland Minerals, the Australian company behind the project, says the mine has the "potential to become the most significant Western world producer of rare earths," adding that it would also produce uranium. But the Chinese giant Shenghe Resources owns 11% of Greenland Minerals—raising concerns about Beijing's perceived design to establish control over the planet's rare earth minerals.
Rare earth minerals constitute a crucial part of the high-tech global supply chain, used in the manufacture of cellphones, other digital devices, and the rechargeable batteries in electric cars. Some 90% of global production is currently under Chinese control.
Inuit Ataqatigiit will have to negotiate a coalition to form a government, needing at least 16 of the 31 seats in the territory's parliament, the Inatsisartut, for a majority. The party itself only won enough votes for 12 seats. The snap election was called after the previous Siumut-led coalition government collapsed amid an internal power struggle. Siumut had governed Greenland since 1979, apart from a period from 2009 to 2013 when Inuit Ataqatigiit was in power. Upon returning to power in 2013, Siumut oversaw the repeal of a law that had banned the extraction of radioactive minerals such as uranium.
Greenland is an autonomous territory that is under the sovereignty of Denmark but effectively self-governing. Although it has a population of just 56,000, the election has been closely followed internationally—both due to the question of control of strategic minerals and because Inuit Ataqatigiit supports formal independence from Denmark.

With advancing technology in miniature MEMS sensors, wearable devices are becoming increasingly popular, facilitating convenient activity detection. One particular application is in sports performance monitoring. This thesis presents novel real-time jump detection and classification algorithms in skiing and snowboarding using a head-mounted MEMS-based inertial measurement unit (MEMS-IMU), which is integrated with a barometric pressure sensor. The key performance variables of the jump are extracted and evaluated for training and/or entertainment purposes. In contrast to the existing jump detection algorithms based on acceleration signals, the proposed algorithm uses vertical velocity and air time in addition to acceleration in the vertical direction. A support vector machine (SVM) is applied to generate a classification model. The jumps are classified into four different groups – Ollie, Standard, Drops, and Step up jumps. The experimental results show that by incorporating the velocity and air time into the detection algorithm, the sensitivity and specificity increase dramatically to 92% and 93%, respectively. In addition, the proposed classification model achieved 80.5% accuracy.

|Title||Material Nodes: Making a Planetoid|
TUTORIAL AS QUOTED FROM SOURCE
love those nodes, here's a simple way to make a planetoid.
This tutorial assumes basic knowledge of a few things, like UV mapping and texture paint, however, if you would prefer, you can substitute a procedural texture for the UV texture, and forget about the geometry node. Also, if you do this, you will probably want the use the 'value' output of the texture node, instead of the 'color' output.
1) we are going to make a planetoid, so, to get started, make a sphere, and UV map it. Using texture paint, create a black and white image of where you want your continents to sit. you can make the water black and the land white, or the other way around, it really doesn't matter. Save the image, we will use it in a moment.
2) select your sphere, and open the materials window. Make a material for the land, with no specular, and a clouds texture for the bump map. Then, make another material for the water, with a high specular, and a stucci, or musgrave texture as the bump map. You can use the same channel, just choose add new, or toggle the appropriate channels on or off in the materials buttons. Anyway, we have two materials, one for land, one for water. make another material to hold the mask texture, or you can put it in one of the channels that's toggled off in your exsisting materials. Anyway, load the mask you just painted into a texture channel.
3) now, split your 3-D screen, and make a nodes window.
4) go back to materials, and on one of them, doesn't matter which, press the 'nodes' button, and you will see two nodes appear in the nodes window. The material will be solid black at this stage, so, in the nodes window, press the red arrow buttons, which will now be highlighted in red, and browse for a material. Choose the land material. Now, with shift+D, duplicate the land node, then, with the browse button, call up the water material. You now have two material nodes, and an output node.
5) we need three more nodes, a mix node, a texture node, and a geometry node. Call these up using shift+A.
6) use the browse button on the texture node to call up your mask texture, and
a) connect the 'UV' output on the geometry node, to the 'vector' input of the texture node.
b) connect the 'color' output of the texture node to the 'fac' input of the mix node.
c) connect the color output for the water node to either of the color inputs of the mix node.
d) connect the color output for the land node to the remaining color input of the mix node.
e) connect the color output of the mix node to the color input of the 'out' node.

A while ago I wrote a script START-DEMO which I use to give demos (You can get the latest/greatest copy HERE. ) This script is also a great teaching tool. You can create your own demo.txt file with commands and explanations and then people can run it using Start-Demo. The great things about this are:
 1. It walks you through a set of commands and can explain what is going on.
 2. You actually run the real commands so you see how it really works.
 3. You can suspend out of the demo to try out variations of your own and then return picking up where you stopped.
 4. You have good control over the demo – you can skip lines, you can repeat things, you can go to a line in the demo, you can find all the lines that match a regular expression. Etc.
Our test manager Michael Naixin Li asked me about how this related to the examples we have in our help system. In response, I wrote the script Export-Demo.ps1 (code below). This script takes one or more help topics and extracts the EXAMPLEs to create a stream of text which can be saved and run as a demo.txt file. Our Help XML cause this script to be a bit chewy. This is the sort of script where you are glad that someone on the internet took the time to write it because you want it but wouldn't want to write it. J
Here is the script:
# Name: Export-Demo
# Version: 1.0
# Author: Microsoft
param ($name)
foreach ($Name in @($Name))
{
$Help = Get-Help $Name -Example
foreach ($Example in $Help.Examples.Example)
{
"# " + $Example.Title
$Example.Remarks |
Where {$_.Text.Trim()} |
%{[Regex]::Split($_.Text,'(.{0,70}(?:\s|$))')}|
%{$x=$_.Trim(); if($x){"# $x"}}
($Example.Code -replace "C:\\PS>").Split("'n")|
where {$_.Trim()}
}
}
BTW – 10,000 thanks to Lee Holmes and his great blog. I used his Email Quoting and Wrapping in 59 Bytes as the source for that chewy looking REGEX code. (I'm soooo glad I didn't have to figure that beast out. J )

How do I get a handle to the module through the exec, so that I can call (in this example) the.run() method? Nov 19 '08 at 6:19

 You can then do getattr(myapp.commands, command) to access the module. Nov 19 '08 at 6:20

 ... or add as command_module to the end of import statement and then do command_module.run()

 - In some version of Python 3+ exec was converted into a function with the added benefit that the resultant referenced created in source get stored into the locals() argument of exec(). To further isolate the exec'd referenced from the local code block locals you can provide your own dict, like an empty one and reference the references using that dict, or pass that dict to other functions exec(source, gobals(), command1_dict).... print(command1_dict['somevarible'])

Similar as _USER_'s solution but reusable and error tolerant described here _URL_
import os
import imp
def importFromURI(uri, absl):
 mod = None
 if not absl:
 path, fname = os.path.split(uri)
 mname, ext = os.path.splitext(fname)
 if os.path.exists(os.path.join(path,mname)+'.pyc'):
 return imp.load_compiled(mname, uri)
 if os.path.exists(os.path.join(path,mname)+'.py'):
 return imp.load_source(mname, uri)
 return mod
The below piece worked for me:
>>>import imp;
>>>fp, pathname, description = imp.find_module("/home/test_module");
>>>test_module = imp.load_module("test_module", fp, pathname, description);
>>>print test_module.print_hello();
if you want to import in shell-script:
python -c ''
The following worked for me:
import sys, glob
fl = glob.glob('modus/*.py')
modulist = []
for i in range(len(fl)):
 fl[i] = fl[i].split('/')[1]
 fl[i] = fl[i][0:(len(fl[i])-3)]
It loads modules from the folder'modus'. The modules have a single class with the same name as the module name. E.g. the file modus/modu1.py contains:
class modu1():
 def __init__(self):
 print self.x
The result is a list of dynamically loaded classes "adapters".

 This is bad not just because it's bad python, but also it's just generally bad code. What is fl? The for loop definition is overly complex. The path is hard coded (and for an example, irrelevant). It's using discouraged python (__import__), what's all that fl[i] stuff for? This is basically unreadable, and is unnecessarily complex for something that is not all that hard - see the top voted answer with its one-liner.

36: How Being a 'Beniyaz' Means Not Being In Any Need
Play • 12 min
Note: The difference between the pronunciations of'marz' and'maraz' is colloquial - while the former is technically correct, the latter is present in everyday usage.
In a world where everything is moving so fast, where the sense of impermanence has only become deeper, most of us feel an intense urge to be able to control everything around us - things, feelings, even people. This can be exhausting.
However, good things come to those who wait and keep calm.
In this episode of Urdunama, we read you some mystic poetry by the great Classical poet, Khwaja Mir Dard, and try to understand if being a 'beniyaz', or someone who is not too concerned, could bring us peace and make us calmer. We also learn - with a little help from Zauq, Ghalib, Firaq, and others - the two different contexts of 'beniyazi' in poetry.

Difference Between Talk and Speak
Talk vs Speak
There are many words in the English language that are synonymous and are usually used interchangeably. Two of these are the words "talk" and "speak."
Both words pertain to the art of communicating our ideas, to verbalize words, or to express sounds. However, "talk" is more often used than the word "speak," and the proposition "to" is more frequently used than "with." An example for this is: "He wants to talk to you," although "He wants to speak to you" may also be said.
If we are to draw a line between them, the major difference between the two is that "speak" is favored in more formal occasions and is commonly used by a single person addressing a group of people. "Talk," on the other hand, is not really for formal usage, and in most cases it implies dialogue between two people, maybe more. One example of this is: "The pupils stopped talking when the Prefect of Discipline started to speak." Another example is: "He is a fan of talking to guests directly, but he is not used to speaking in front of a large crowd."
These verbs are not connected with a direct object (intransitive), but either a preposition (prepositions: about, to, with, for, etc.) or an adverbial modifier. Adverbial modifiers usually follow "talk" or "speak."
It is good to remember the following phrases when using "talk": talk back; talk sense, nonsense; talk to you later; talk something over; great talkers are little doers; now he is talking; talking about reality; talk less, act more.
It would also be good to remember these phrases when using "speak": speak many languages (speak English, German, etc.); speak up; frankly speaking; Francis is speaking with Kim on the phone; speak fluently, easy; speak for oneself; speaking of the devil; first think, then speak; speak only of the truth.
There are instances when both "speak" and "talk" can be used for both formal and informal situations. You can use the phrases: speak one on one or talk one on one. This is also a common use of words: talk personally or speak personally. Another example is: talk in secret or speak in secret.
To peg these concepts to the ground, let's cite situations in our daily experiences. Imagine a situation when someone is giving a speech to an audience, and in that audience two children are having a conversation and not listening to the speech. This is irritating the rest of the audience. We can simply say: While the minister was speaking at the meeting, two children were told to be quiet because they were talking to one another and making it difficult for people to concentrate.
1. "Talk" is most often used compared to "speak."
2. There may always be an exception to every rule. However, let us take note that the bottom line is that "speak" is used for formal address while "talk" is usually used for an informal setting.
3. A talker makes the conversation chummy or interesting while a good speaker does well when conversing to a group of people as a whole.

All News Releases By Date
U.S. EPA settles with JWS Refrigeration for $53,481 for illegal importation of ozone-depleting substances
Release Date: 11/19/2007
Contact Information: Dean Higuchi, _PHONE_, _EMAIL_
(11/19/07) HONOLULU – The U.S. Environmental Protection Agency today fined JWS Refrigeration & Air Conditioning, Ltd., a Tamuning, Guam refrigeration and heating equipment services company, $53,481 for allegedly importing banned refrigerants in violation of the Clean Air Act.
The company allegedly imported 25,402 kg of hydrochlorofluorocarbon 22, an ozone-depleting substance, from sources outside the United States, a violation of the stratospheric ozone protection regulations.
"To protect stratospheric ozone, the Clean Air Act limits the importing of ozone depleting chemicals into the United States," said Deborah Jordan, director of the EPA's Air Division for the Pacific Southwest region. "Companies in Guam and other U.S. territories are not excluded and must comply with all stratospheric ozone protection regulations."
A May 2006 inspection by the Guam EPA, in consultation with the U.S. EPA, identified the violations by JWS Refrigeration.
High in the atmosphere, the stratospheric ozone layer is the earth's protective shield against excessive ultraviolet radiation. Overexposure to ultraviolet radiation is responsible for increased risk of skin cancer and cataracts, depressed immune systems, decreased crop output, and the destruction of plankton, a critical link in the oceanic food chain.
The U.S. EPA's stratospheric ozone protection program aims to prevent depletion of the ozone layer through the production phase-out and use restriction of refrigerants. Among other restrictions, the program forbids the importation of ozone-depleting substances.

---------------------------
STRUCTCOMPVIS(s1,s2) opens an HTML differencing report comparing two structures.
This is useful for quickly finding subtle differences between 2 structures. I find it particularly useful when working with large handles structures from GUI applications.
Ex:
% Find which properties are different between two graphics objects
subplot(211);l1 = plot(1:10)
subplot(212)l2 = plot(1:10,'r')
structcompvis(get(l1),get(l2))

Comments and Ratings (3)
Oops - I mistakenly wrote TEMPNAME above in place of TEMPDIR. Also, the issue seems to be my fault because I changed TEMPDIR while debugging this code. However, I think it is cleaner to use TEMPNAME to create the file names. Either way, the file names displayed by VISDIFF will generally not correspond to the user's variable names.
I ran into a few problems running this code:
1. It uses the directory given by the environment variable TEMPNAME. Oddly, though, TEMPNAME is incorrect on my machine.
2. It calls VISDIFF, which works asynchronously. As a result, STRUCTCOMPVIS deletes the temporary files before VISDIFF has managed to open them.
3. It displays the contents of the structures in the command window as well as the comparison window.
4. The issue regarding lengths of field names is due to an unnecessary parameter handed to VISDIFF.
Here is some code that fixes all these problems:
% Sort structures, to ignore order
s1 = orderfields(s1);
s2 = orderfields(s2);
% Write structures to temp files
structInStringFormat = evalc('disp(s1)');
f1 = tempname;
fid = fopen(f1,'w+');
fprintf(fid,'%s\n',structInStringFormat);
fclose(fid);
structInStringFormat = evalc('disp(s2)');
f2 = tempname;
fid = fopen(f2,'w+');
fprintf(fid,'%s\n',structInStringFormat);
fclose(fid);
% Use visual differencing report
visdiff(f1,f2)
pause(1)
% Delete temp files. Feel free to keep these.
delete(f1)
delete(f2)

2.10: Dimensionless forms of Planck's equation
 - Page ID
 8020
 - [ "article:topic", "authorname:tatumj" ]
 The Planck functions (of wavelength or frequency and temperature) can be collapsed on to dimensionless functions of a single variable if we express the exitance in units of the maximum exitance, and the wavelength or frequency in units of the wavelength or frequency at which the maximum occurs. Equations 2.7.1-4 and 16-20 will be needed to achieve this, and the reader might enjoy doing it as a challenge. (I said "might".) The results are
 \[M_\lambda = \frac{b_1}{\lambda^5 \left( e^{x_1 / \lambda}-1\right)} \tag{2.10.1}\]
 \[N_\lambda = \frac{b_2}{\lambda^4 \left( e^{x_2 / \lambda}-1\right)} \tag{2.10.2}\]
 \[M_\nu = \frac{b_3 \nu^3}{e^{x_3 \nu} -1}\tag{2.10.3}\]
 \[N_\nu = \frac{b_4 \nu^2}{e^{x_4 \nu} - 1} \tag{2.10.4}\]
 where \[b_n = e^{x_n} -1 \quad (n=1,2,3,4) \tag{2.10.5} \]
 The numerical values of \(x_n\) are given in equations 2.7.8-11, and the values of \(b_n\) are
 \[b_1 = 142.32492 \tag{2.10.6}\]
 \[b_2 = 49.435253 \tag{2.10.7}\]
 \[b_3 = 15.801016 \tag{2.10.8}\]
 \[b_4 = 3._PHONE_ \tag{2.10.9}\]
 The numbers \(x_n \ y_n, \ b_n\) are independent of the values of any physical constants such as \(h\), \(c\) or \(k\), and will not change as our knowledge of these values improves. These functions, which are independent of temperature, are drawn in figures II.1,2,3,4 shown at the end of this chapter.

 Example
 Here is an example to show the use of the dimensionless functions to calculate the blackbody radiance quickly. What is the radiance per unit wavelength of a \(5000 \ \text{K}\) black body at \(400 \ \text{nm}\)? You may prefer to calculate this directly from equation 2.6.1, but let's try it using the dimensionless form. From equation 2.7.1 we find that the wavelength at which maximum exitance per unit wavelength occurs is \(579.56 \ \text{nm}\), and therefore our dimensionless wavelength to be inserted into equation 2.10.1 is 0.6902. This gives a radiance per unit wavelength interval (in units of the maximum) of 0.6832. But equation 2.7.16 gives the maximum radiance per unit wavelength interval as \(4.0178 \times 10^{13} \ \text{W m}^{-2} \text{m}^{-1}\) and therefore the radiance at \(400 \ \text{nm}\) is \(2.745 \times 10^{13} \ \text{W m}^{-2} \text{m}^{-1}\).
 I don't think there is much point in integrating the dimensionless functions 2.10.1-4 over all wavelengths and frequencies, but, for the record:
 \[ \int_0^\infty M_\lambda d \lambda = \frac{\pi^4 x_1}{15 y_1} = 1.52080 \tag{2.10.10}\]
 \[ \int_0^\infty N_\lambda d \lambda = \frac{2 \zeta (3) x_2}{y_2} = 1.97199 \tag{2.10.11}\]
 \[ \int_0^\infty M_\nu d\nu = \frac{\pi^4}{15x_3 y_3} =1.61924 \tag{2.10.12}\]
 \[ \int_0^\infty N_\nu d\nu = \frac{2 \zeta (3)}{x_4 y_4} = 2.32946 \tag{2.10.13}\]
 Figure II.1. Blackbody exitance per unit wavelength interval. The equation is equation 2.10.1, with constants given by equations 2.10.6 and 2.7.8. The maximum value is given by equations 2.7.16 and 2.7.27. It occurs at a wavelength given by equations 2.7.1 and 2.7.12.

 Figure II.2. Blackbody photon exitance per unit wavelength interval. The equation is equation 2.10.2 with constants given by equations 2.10.7 and 2.7.9. The maximum value is given by equations 2.7.17 and 2.7.28. It occurs at a wavelength given by equations 2.7.2 and 2.7.13.

 Figure II.3. Blackbody radiance per unit frequency interval. The equation is equation 2.10.3 with constants given by equations 2.10.8 and 2.7.10. The maximum value is given by equations 2.7.18 and 2.7.29. It occurs at a frequency given by equations 2.7.3 and 2.7.14.

 Figure II.4. Blackbody photon radiance per unit frequency interval. The equation is equation 2.10.4 with constants given by equations 2.10.9 and 2.7.11. The maximum value is given by equations 2.7.19 and 2.7 30. It occurs at a frequency given by equations 2.7.4 and 2.7.15.

What does 'godspeed' mean? What is the definition of 'godspeed' / 'god speed'?
The words "God speed" are found only in the King James Version of the Bible, and only in 2 John 1:10–11: "If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed: For he that biddeth him God speed is partaker of his evil deeds." John is saying we should not wish a false teacher of the gospel a certain success or blessing brought by God.
The origins of the phrase godspeed meant to wish someone success, or a wish that God would prosper someone. It comes from the Middle English "God speid", or "God spede you" from the 15th century. It was used to bless someone starting a journey or some special endeavor.
Spede, or speid, is not about swiftness, but prosperity. It is similar in nature to saying goodbye—which originated with "God be with ye" in English. In French, the salutation adieu, and in Spanish adios, also have connections with God, both originally meaning "I commend you to God."

Genetic variation within and among wild Turkey, Meleagris gallopavo, subspecies was measured using DNA sequencing and PCR-RFLP analysis of a 655 bp portion of the mtDNA D-loop region. DNA sequencing from 25 individual Eastern, Merriam, Rio Grande and domestic Turkeys revealed 16 polymorphic sites. Parsimony and neighbor-joining analysis did not show support for the four wild Turkey subspecies studied. PCR-RFLP analysis of 118 individuals revealed 13 distinct haplotypes. Haplotype variation was detected in all wild Turkey populations, and Wright's F-statistics revealed pronounced differentiation (FST = 0.302) among populations. Based on these data, non-native wild Turkey populations do not appear to have suffered a genetic bottleneck since their reintroduction.

If your sewer lines are installed sometime between the 1940s to 1970s, chances are they are made from Orangeburg. While this material has a life expectancy of 50 years, it can fail sooner than expected. Fortunately, Snowbridge Inc. offers trenchless pipe repair in Breckenridge, CO, to restore your damaged Orangeburg pipes. Read on to find out how this solution works.
The Problem With Orangeburg Pipes
Also called "no-corrode" pipes, Orangeburg pipes are composed of asphalt-soaked paper and wood pulp. This mixture makes them light and fragile, which is why it's no surprise that they are vulnerable to environmental stresses. For one, they can deform due to moisture and pressure, leading to plumbing issues. They also start to fail within 10 years.
How Trenchless Solutions Will Benefit Orangeburg Pipes
Trenchless pipe lining can rectify the damage caused by wear and tear, invasive tree roots, shifting soil, and other issues, restoring your pipes to like-new condition. It involves pushing an epoxy-coated liner into the pipeline, then cures and hardens to form a new durable pipe. As a result, your Orangeburg pipes can serve you for over five decades.
Trenchless sewer repair can do the following for your damaged Orangeburg pipes:
- Seal joint connections
- Cover holes and cracks
- Address missing pipes
- Even out offsets
Unlike the conventional dig-and-replace techniques, trenchless sewer replacement doesn't require digging up your entire yard. The entire process takes place underground, making it efficient and non-intrusive. This also means you don't have to worry about restoring your damaged landscaping once the project is done. In turn, you save time, money, and headache.

It is mating season for fish when it is really hot and dry.
Mating between fish is called spawning. Spawning season is different for each species of fish.
Mating season for fish will be different each species of fish. Some fish may mate year round such as tropical fish, while other mate during the spring or summer.
It will be chasing it around near it's butt and stabbing it with it's gonopodium...
Sexually. Like a mixture between reptile mating and fish mating.
Entirely depends on the species.
Yes they do

the betta fish is a very beautiful fish but maybe put them in a seperate bowl for awhile.
Spawning is quite simply the act of mating in fish.
* 2 fish in love with each other * 2 fish breeding * A beautiful dance that fish do during mating season
Fish cannot be made to mate , except by artificial means. Fish can be allowed to mate in captive situations by several known methods. Providing fish with correct temperature, water condition, suitable mating environment, changing those conditions to match normal wild mating conditions may allow mature fish to mate. Sometimes mating fish in captivity is easy as feeding them and keeping them in suitable water conditions. Some fish have never been bred in captivity and will only breed in wild conditions.
They are the same thing.
its may not be easy but you can tell around spring. around spring it is mating time and the if you look right on top of the tank the male will look even on both sides and the female will look bloated on one side
It is in the Spring and goes on to part of the early Summer.
Sometimes yes; and vice versa.
It depends on what kind of fish it is; some fish you can tell and others you cannot tell.
You can tell if a fish is a male because the Male fish is smaller than a Female fish
You could tell if a snail is mating because their slimel part of their body is hooked up with each other.
They breed, (Give Birth) to another fish a few days after mating, but be careful because the fish eggs are small and may be eaten by fish. (Not Sure answer but is close)

palomino horse, American light horse that, contrary to popular opinion, is not a breed but a color type. The palomino is a characteristic golden, creamy tan, with an almost white mane and tail. White stripes on the face and white stockings are common. This coloring occurs in several breeds of light horse. Palominos were probably first selected for their beautiful color in Spain. They accompanied the conquistadors to the New World, where they were perpetuated by early Mexican horse breeders. They were discovered by Americans in California during the Mexican-American War, and are now popular parade and show horses; fanciers in the United States are trying to establish the palomino as a breed. Palominos have Arabian or Thoroughbred features, stand about 15 hands (60 in./150 cm) high, and weigh about 1,100 lb (500 kg).

PAOs vs PAGs
PAO_vs_PAG
Q: What's the main difference between PAOs & PAGs?
Let's start off with definitions!
PAO: Polyalphaolefin
PAG: Polyalklene Glycol
While both are synthetic oils they are classified under different Groups of Base oils. PAOs have their own Base oil Group IV while PAGs fall into the Group V (catch all).
PAOs
PAOs are actually hydrogenated oligomers of an α-olefin and there are different methods of oligomerisation. Due to this process, PAOs have very good low temperature properties and the products are wax free! Additionally, their lower volatilities also allow them to operate over a wide temperature range. Usually, they can be used in a lot of versatile applications such as gearboxes, screw compressors, fans, motors and even automotive!
However, PAOs have a low polarity which gives rise to poor solvency of polar compounds and issues with seal performance.1
PAGs
On the other hand, PAGs can differ depending on their structure. For instance, Ethylene is water soluble while Propylene is not, however, neither are oil soluble. Both experience significant chemical reactions producing sludge like deposits when mixed with mineral oil.
Usually, their properties include a wide viscosity range, low pour points, good lubricity, low toxicity and non-flammable in aqueous solutions. PAGs are typically always found in fire-resistant hydraulic fluids as well as industrial gear oils, compressor lubricants, heat transfer liquids and metalworking fluids.1
Compatibility
Both products need to be tested for compatibility with mineral oils before any mixing occurs. Additionally, most lubricant suppliers deem PAOs & PAGS as "filled for life" solutions which last for a longer time compared to mineral oils. Typically, the purchase of these products are more expensive than mineral oils, however if one looks at the cost of waste disposal and reduced downtime (due to decreased shutdowns for oil changes) the overall cost of the lubricant is by far less than that of mineral oil.

Recently introduced to the UK, this Brazillian 'tree' fern does eventually form short stem as it matures. It's for the newly emerging bright red fronds that it is most sought after. These fronds are a good size, and they form a distinctive shuttlecock shape so it is quite architectural. As they mature the fronds turn bronze, then finally settle on a rich green colour as the season progresses.
- Garden care: It will usually require some winter protection for the first few years. Incorporate lots of well-rotted leaf mould or garden compost into the planting hole. Keep well watered during the growing season.
