Hare Krishna dear devotees,
Some times we get confused between what exactly is sin and what is reaction? What is the difference between these two? I recently heard a very nice explanation by HH Bhaktividya Purna maharaj and I am copying it's transcript.
What is the difference between reaction and sin?
HH Bhaktividya Purna Maharaj :
Reaction will be you are put into the same situation in which you are giving that trouble, and you are on the other side. That's reaction. Sin means going to hell for some time and going through all the animal species to be punished before you come to that situation.
The person who according to the Vedic literature kills an animal in sacrifice there is no sin. He'll be elevated, the animal will be elevated. As far as karma-kanda goes it looks good all the way round. But there is still reaction that in the future the person that performed the sacrifice will be the animal, and the animal will be the person performing he sacrifice. Now the animal will get to sacrifice you. But it's all good, it's all pious activity. This is the downside. The reaction is there but they won't go to hell for killing the animal and take birth in so many animal species. It's still circle. That's why if one is intelligent one worships Krsna and gets out of that, because it's stupid. Even though it's on this nicest level it's still stupid. Most of the time the two go together, when there is sin there is reaction. But when you perform pious activities you can have reaction without sin. Just like you can have a good reaction and there is no sin. So you can also have a bad reaction without sin. But technically it's all considered sinful because it's not connected to the Lord. Good and bad when it's not connected to the Lord it's sin.

Definition of a Crime Victim
The Attorney General's Guidelines for Victim and Witness Assistance define a victim as a person that has suffered direct physical, emotional, or pecuniary harm as a result of the commission of a federal crime. If the victim is a non governmental institution, such as a bank or corporation, this definition includes a representative of that institution. Government agencies are not considered victims for the purpose of victim services but federal government employees who are harmed in the performance of their duties are considered victims. If the victim is deceased, under 18 years of age, incompetent or incapacitated, this definition includes one of the following persons (in order of preference): a spouse, a legal guardian, a parent, a child, a sibling, another family member; or another person designated by the court.
Definition of a Witness
The Attorney General's Guidelines for Victim and Witness Assistance define a witness as a person who has information or evidence concerning a crime, and provides information regarding his or her knowledge to a law enforcement agency. Where the witness is a minor, the term witness includes an appropriate family member or legal guardian. The term witness does not include a person who is solely a defense witness.
The U.S. Attorney's Office will make its best efforts to ensure your rights are protected. You may seek the advice of an attorney with respect to these rights. If you believe that an employee of the United States Attorney's Office failed to provide you with one or more of these rights, you may file an administrative complaint, as provided under 28 CFR §45.10. Please contact the United States Attorney's Office to obtain information about these procedures.

Abstract: Maintaining both a population of native Humpback Chub (Gila cypha) and non-native Rainbow Trout (Oncorhynchus mykiss) are stated goals for management downstream of Glen Canyon Dam (GCD) on the Colorado River, yet these species have very different habitat requirements and often times the Rainbow Trout prey upon the Humpback Chub. Habitat conditions in the river downstream of GCD have been extremely altered with moderate flows, cold water temperature, and a much reduced sediment load compared to historic conditions. These physical habitat characteristics create ideal conditions for the non-native trout and have reduced the habitat quality for the chub. In addition to the change in habitat, the rainbow trout and other introduced species predate on the chub. Several management actions from mimicking high flow events to mechanical invasive species remove have taken place to date with differing success. It may also be natural fluctuation such as drought can override the management actions in terms of drivers of the humpback chub population. Recent studies have found that under drought conditions, humpback chub populations have been increasing with warmer water. Under such an altered condition, can both of the species coexist and how does societal desire for recreational trout fishing compete with maintaining a non-recreational fish such as the Humpback Chub? This question will ultimately have to be addressed if a longterm solution is to be found.
Can Humpback Chub and a Blue Ribbon Trout Fishery Coexist in the Grand Canyon?

Consider the integral
$\int_0^{\pi/3}x\cos^2(x^2)dx $
Here, I see two terms: x, and $\cos^2(x^2)$. I would normally use integration by parts, but I run into major issues because of the $\cos^2(x^2)$, specifically the $x^2$.
I take $\cos^2(x^2)$ as $u$, x as $dv$, and after the simplifying of some constants, I have
$\frac12 x^2\cos^2(x^2) + 2\int_0^{\pi/3}x^3\cos(x^2)\sin(x^2)$
*because I found the derivative of $\cos^2(x^2)$ was $-4x\cos(x^2)\sin(x^2)$ and the integral of x as $\frac{x^2}2$
but you can see, this new integral isn't very helpful. I can't use parts with an integral with three terms being multiplied, so I'm kind of stuck.
I do know that $\cos^2x = \frac{1 + \cos(2x)}2$. That could be useful, but I don't know if this applies to different forms of $x$ such as $x^2$, like it does for $ax$, as $a$ as a constant.
How can I find the integral of these kinds of functions, where trigonometric functions have squared or cubed composed functions inside? Any help would be appreciated.
Much thanks

Since you know that $\cos^2x = \frac{1 + \cos(2x)}2$, try the substitution $u = x^2$.

I have it! Thank you very much. – Zolani13 Apr 1 '12 at 5:52
Substitute $t=x^2$, so $dt=2x dx$, hence :
$I= \frac{1}{2} \int \limits_{0}^{\pi^2/9} \cos^2t \,dt$
Now use a fact that :
$\cos 2t=2\cos^2 t -1$

(The original Chinese version of this article is written by Licter Chang and published on MakerPRO)
Have you ever thought about the reason why founding a hardware startup is so hard? Part of the reason is because your money disappears fast in hardware manufacturing, and it is a known fact that many hardware startups are struggling with raising enough funding for their survival. Additionally, the categorization of hardware itself is complicated. Often times, it is hard to build up the right team and find appropriate manufacturers. However, there are ways to make it easier for hardware startups to break down responsibilities and find the right partners.
Below, we break different roles in the hardware sector down to six categories:
1. The Intensifiers
People under this category are responsible for building the foundation for hardware projects, from dealing with signals, avoiding extra disturbance, and enhancing the efficiency of batteries. These people are usually hardware engineers or circuit engineers.
2. The Releasers
People under this category are those in charge of wireless signals, and communication systems. They are usually antenna engineers and radio-frequency engineers, who will be playing more and more important roles in the coming years.
3. The Practitioners
People under this category are in charge of operating hardware systems, which enables the communication between users and devices through interface. In addition to defining the function of chips and enhancing the efficiency of using memories, they also need to take care of communication between different interfaces. These people are usually firmware engineers.
4. The Changers
People under this category control changes in the manufacturing process, and adjust variables to stabilize the system. These people are usually the process engineers.
5. The Realizers
People under this category usually deal with designing the appearance of products and packaging the products. If a product wants to have a perfect outlook, then the role of these realizers are very important. These people are usually industrial designers, who understand both aesthetic beauty and structure.
6. The Specializers
People under this category are not in charge of any particular aspect of hardware development, but they help to deal with retailers and business development. They are usually project managers who make sure each milestone is carried out nicely.
It is undeniable that founding a business needs to face many challenges and risks. The selection of team members is one of the aspects that requires careful reasoning, because a suitable team member can have crucial impacts on the company's future.


Medialunas de manteca
July 2016
Medialunas (literally half moons) have been called the Argentinian croissant. They are smaller than their French counterparts and come in two flavors - sweet and savory. These pastries are a daily staple for many Argentinians, enjoyed any time of day. The medialuna de manteca is the sweet, plump, buttery version that usually requires a napkin at some point.
Medialunas de Manteca
1oz bakers yeast
1 teaspoon sugar
1 tablespoon warm water
21/4 cups (500g) flour
1/4 cup (45g) sugar
1 teaspoon salt
1 egg
Empaste (butter filling):
1 cup (260g) butter
1/4 cup (50g) flour
Almibar (simple syrup):
1 cup (200g) sugar
1/2 cup (100g) water
Making the Dough
 1. Combine the yeast, sugar and water. Mix until creamy and frothy. Set aside and let it rise.
 2. In a separate bowl, combine the flour, sugar, and salt. Mix.
 3. Once the yeast has risen, add it to the flour, sugar, salt mix and fold in 1 egg.
 4. Knead and keep adding water (about 1 cup) slowly until you get a soft dough.
 5. Cover and let it rise.
 6. Combine in another bowl flour and butter and mix to make the empaste (butter filling).
 7. Stretch the dough in a rectangle and smear the empaste on top. Fold it in 3 parts, and let it rest.
 8. Roll it out into a rectangle. Fold the rectangle in 3 parts, turn 90 degrees. Roll out again making a rectangle, and fold in 3 parts.
 9. Wrap in film and leave in refrigerator overnight.
 10. Unwrap, sprinkle flour on your work surface, roll out and fold into 2 parts.
 11. Leave it to rest for 1 hour at room temperature.
Shaping the Medialunas
 1. Stretch the dough in a rectangle. Cut in 6" strips. Then cut into multiple triangles, about 4" at the base of the triangle.
 2. Roll the widest part of the triangle to the opposite point. Curve and place the medialuna on a buttered sheet.
 3. Brush an egg wash on each medialuna.
 4. Bake at 375° Fahrenheit until golden on top.
Glazing and Eating
 1. When the medialunas are in the oven, bring the alimbar (sugar and water) to boil until there are numerous small bubbles.
 2. Brush the cooled almibar on top of the warm medialunas when you take them out if the oven.
 3. Shove into mouth as soon as possible. Have fun and enjoy!!

The Perfecting the Pillars eight-book series teaches students about the first two pillars of Islam: shahada (testifying to the oneness of Allah) and salah. The other three pillars of Islam will be covered in the remaining six books of the series, which are currently under development.
The lessons in this series are based on short stories that make learning facts more enjoyable. The stories feature young children that the student can identify with, and they take place in different countries (America, Saudi Arabia, and Egypt) to give students a world view of Islam. They feature different economic and social environments to allow students to see different family structures and situations (i.e., nuclear families, orphans, needy people, widows, and interracial families).
Each book features:
- Quran and hadith references
- Highlighted vocabulary
- Review section at the end of each lesson
- Illustrations (no animals or human beings)
- Glossary of Arabic terms
These short stories feature five-year-old twins, Muhammad and Maryam, as they learn about tawheed (the oneness and unique nature of Allah). This is Part 1 of two parts in the series.

Call response WebSockets in Play Framework
I got a question from a Play user about implementing call/response WebSockets in Play Framework. This is not something that comes up that often, since it means using WebSockets to do basically what AJAX does for you, so what's the point? But here are some use cases that I've thought of:
 - You have some transformation of a stream that can only be done on the server side. For example, perhaps the transformation requires some heavy database work, or is too computationally expensive for a mobile client, or perhaps you want to encrypt the stream with a key that is private to the server.
 - You are already processing a stream of events from the server using WebSockets, and the responses to the calls are just more events in this stream, so you'd like to share the same transport mechanism for these events.
 - Your application is particularly chatty, and you don't want the overhead of the HTTP protocol on each call/response.
There are possibly more use cases - WebSockets is quite a new technology and as an industry we haven't really settled on what it's best use cases are.
A simple echo implementation
A Play WebSocket is implemented by providing an iteratee that consumes messages from the client, and an enumerator that produces messages for the client. If we simply wanted to echo every message that the client sent us, then we would want to return an iteratee whose input becomes the output of the enumerator that we return. Play doesn't come with anything out of the box to do this, but we will probably add something out of the box that does this in a future release. For now, I'm going to write a method called joined, that returns a joined iteratee/enumerator pair:
 * Create a joined iteratee enumerator pair.
 * When the enumerator is applied to an iteratee, the iteratee subsequently consumes whatever the iteratee in the pair
 * is applied to. Consequently the enumerator is "one shot", applying it to subsequent iteratees will throw an
 * exception.
def joined[A]: (Iteratee[A, Unit], Enumerator[A]) = {
 val promisedIteratee = Promise[Iteratee[A, Unit]]()
 val enumerator = new Enumerator[A] {
 def apply[B](i: Iteratee[A, B]) = {
 val doneIteratee = Promise[Iteratee[A, B]]()
 // Equivalent to map, but allows us to handle failures
 def wrap(delegate: Iteratee[A, B]): Iteratee[A, B] = new Iteratee[A, B] {
 def fold[C](folder: (Step[A, B]) => Future[C]) = {
 val toReturn = delegate.fold {
 case done @ Step.Done(a, in) => {
 case Step.Cont(k) => {
 case err => folder(err)
 toReturn.onFailure {
 case e => doneIteratee.failure(e)
 if (promisedIteratee.trySuccess(wrap(i).map(_ => ()))) {
 } else {
 throw new IllegalStateException("Joined enumerator may only be applied once")
 (Iteratee.flatten(promisedIteratee.future), enumerator)
This code might be a little scary if you don't understand iteratees, but as I said we will probably add this to Play itself in future. The rest of the code in this blog post will be simple.
Now that we have our joined iteratee/enumerator, let's implement an echo WebSocket. For the rest of this post we'll be assuming that all our WebSockets are sending/receiving JSON messages.
def echo = WebSocket.using[JsValue] { req =>
So now we have an echo call/response WebSocket. But this is not very useful, we want to do something with the incoming messages, and producing new outgoing messages as responses.
Processing messages
So now that we've expressed our call/response in terms of a joined iteratee/enumerator, how can we transform the call messages to be different response messages? The answer is enumeratees. Enumeratees can be used to transform iteratees and enumerators. We return both an enumerator and an iteratee, so which one do we transform? The answer is it doesn't matter, I'm going to use it to transform the iteratee. The enumeratee that we're going to use is the map enumeratee:
def process = WebSocket.using[JsValue] { req =>
 val (iter, enum) = joined[JsValue]
 ([JsValue] { json =>
 "status" -> "received",
 "msg" -> json
 } &> iter, enum)
Enumeratees are one of the most powerful features of iteratees for end users. You could use any enumeratee here, but let's look at some examples of other common use cases.
What if we don't want to return a response to every message? There are numerous ways to do this, but the simplest is to use the collect enumeratee, which takes a partial function:
def process = WebSocket.using[JsValue] { req =>
 val (iter, enum) = joined[JsValue]
 (Enumeratee.collect[JsValue] {
 case json if (json \ "foo").asOpt[JsValue].isDefined =>
 "status" -> "received",
 "msg" -> json
 } &> iter, enum)
Perhaps we want to produce many responses for a single input. The mapConcat enumeratee can be used in this case, with our map function returning a sequence of JsValue messages to return:
def process = WebSocket.using[JsValue] { req =>
 val (iter, enum) = joined[JsValue]
 (Enumeratee.mapConcat[JsValue] { json =>
 "status" -> "received",
 "msg" -> json
 Json.obj("foo" -> "bar")
 } &> iter, enum)
What if we want to do some blocking operations? In Play 2.2, this will be able to be done simply by providing an execution context suitable for blocking calls to whichever enumeratee you decide to use, but Play 2.1 does not yet support this, so we have to dispatch the callback to another execution context ourselves. This can be done using the mapM enumeratee:
val ec: ExecutionContext =...
def process = WebSocket.using[JsValue] { req =>
 val (iter, enum) = joined[JsValue]
 (Enumeratee.mapM[JsValue] { json =>
 Future {
 // Some expensive computation, eg a database call, that returns JsValue
 } &> iter, enum)
Pushing from an external enumerator
You may want to combine your call/response messages with messages from some other enumerator that spontaneously pushes messages to the client, for example a broadcasting enumerator for all clients. This can be done by interleaving your joined enumerator with the external enumerator:
val globalEvents: Enumerator[JsValue] =...
def process = WebSocket.using[JsValue] { req =>
 val (iter, enum) = joined[JsValue]
 ([JsValue] { json =>
 } &> iter, Enumerator.interleave(enum, globalEvents))
Using WebSockets in a call response style may be something that your application needs. If so, using enumeratees to map the stream of messages coming in to messages going out is the most natural and idiomatic way of doing this in Play. It allows you to call on the large number of composable enumeratees that Play provides out of the box, and makes your code simple and easy to reason about.
Iteratees for imperative programmers
When I first heard the word iteratee, I thought it was a joke. Turns out, it wasn't a joke, in fact there are also enumerators (that's ok) and enumeratees (you're killing me). If you're an imperative programmer, or rather a programmer who feels more comfortable writing imperative code than functional code, then you may be a little overwhelmed by all the introductions to iteratees out there, because they all assume that you think from a functional perspective. Well I just learnt iteratees, and although I'm feeling more and more comfortable with functional programming every day, I still think like an imperative programmer at heart. This made learning iteratees very difficult for me. So while I'm still in the imperative mindset, I thought this a very good opportunity to explain iteratees from an imperative programmers perspective, taking no functional knowledge for granted. If you're an imperative programmer who wants to learn iteratees, this is the blog post for you. I'm going to specifically be looking at Play's Iteratee API, but the concepts learnt here will apply to all Iteratees in general.
So let's start off with explaining what iteratees, and their counterparts, are trying to achieve. An iteratee is a method of reactively handling streams of data that is very easily composable. By reactive, I mean non blocking, ie you react to data being available to read, and react to the opportunity to write data. By composable, I mean you write simple iteratees that do one small thing well, then you use those as the building blocks to write iteratees that do bigger things, and you use those as the building blocks to write iteratees to do even bigger things, and so on. At each stage, everything is simple and easy to reason about.
Reactive stream handling
If you're looking for information about iteratees, then I'm guessing you already know a bit about what reactive stream handling is. Let's contrast it to synchronous IO code:
trait InputStream {
 def read(): Byte
So this should be very familiar, if you want to read a byte, you


Why do we find it so difficult to trust?
No Comments
Trust is such an important attitude to cultivate in practice, and in life. But sometimes when stuck in a situation where we aren't feeling too comfortable or happy, be it in ourselves, or our partners, the direction of our life or even the health of our bodies it can feel pretty difficult to trust the process and know that on some greater level it's going to be ok.
So how do we practice trust?
Jon Kabat Zinn reminds us in the video below that we can start with something as simple as our breath because luckily the breath can take care of itself, we don't need to tell ourselves to breathe, we can rest pretty easy at night knowing that while sleeping it is happening. We can also learn to trust in the wisdom of our bodies and what we feel; trusting that the ears can actually hear, the eyes can actually see. That the organs take care of all the things they need to, to keep us alive.
From there we might begin to take a little more notice of the signs our body is telling us around feelings of being tired, anxious, overly stressed, sad, fearful and rather than talking our way out of it with our minds or finding some quick fix to feel less discomfort, maybe we can listen in and trust a little more what the experience in our body is trying to tell us?
The more we can learn to bring trust to our experience, trusting ourselves and what's actually going on vs. trying to control it and make it better, the more we can learn to bring trust to our relationships, to other people and to the challenges we face in life so that hopefully with practice we can reside in our own ability to meet whatever comes towards us.

As we have mentioned, "Pink Slime" is a naturally occurring bacterium (of the newly formed genus Methylobacterium).
It is NOT pathogenic (not harmful).
Watch the video
This is NOT a form of Algae; it is animal not
seen/experienced in many places outside of swimming pools.
It is given its name because it is Pink-pigmented and forms a heavy, protective
slime coating providing itself with an unusually high level of protection
oftentimes found WITH White Water Mold.
Pink slime is very resilient against halogen-based
(chlorine, bromine) as well as non-halogen sanitizers or germicides. It can remain a contaminant even after treatment.
This is NOT a biguanide problem ONLY. Nor does using "biguanide" based
sanitizers cause or contribute to its existence or growth. That being
said, to be truthful, we do see a somewhat larger percentage of biguanide treated pools
affected by pink slime as compared to halogen (chlorine & bromine) treated pools.
The bacterium has a natural affinity for the matrix that exists on the surface of PVC plastics; it will attach itself to & inside of the matrix, allowing it to re-contaminate long after it appears that it has been destroyed (includes pool toys, floats, ladders, steps, fountains, automatic pool cleaner parts, skimmer baskets, weirs, directional fittings,
garden hoses, etc.). Remaining small quantities of the bacteria can lead to a re-establishment of the problem.
Pink Slime prefers areas that are "dark" (not exposed to direct sunlight,
such as underground piping, home piping, etc.) & with "slow moving"
or "not constantly moving" water.
in mind that Pink Slime CAN be physically removed (comes off with brush or
fingers). If what you think is Pink Slime, but appears to be more PURPLE &
is not removed by brushing, you have another problem called Purple Cyanurate.
Click here for the details.
In swimming pools, pink slime is caused by improper water & pool maintenance, environment, poor circulation
to name a few. After regular tracking of homeowners swimming pools
affected by pink slime, we have noted & present some commonalities:
There appears to have occurred a
dramatic rise in the reported cases of pink slime especially over the past 5 to
10 years. I'll go into more depth with this comment later.
Many, but not all, affected pools have
"smaller (under) sized" cartridge filters. (i.e. using a 75 sq ft filter on a 24
ft Rnd aboveground pool or a 90 sq ft filter on a 15 x 30 inground pool).
Pools get 6 hours or less of direct
sunlight on the pool surfaces.
Pool owners always leave the solar
blanket on AND don't chemically clean the blanket the recommended 2 times per
year to remove the accumulated biofilm.
"Shocking" or oxidizing of the pool
water is not done with the recommended label instructions.
Rainy pool seasons see a dramatic rise
in the cases of pink slime.
Customers regularly add fresh water
from their tap without letting the hose-water run for a couple of minutes (slime
is present in the garden hose).
Pools with sand filters are not
changing the sand every 2 to 3 years AND not chemically cleaning the filter sand
3 times a season (once every 6 to 8 weeks).
Newer observation, although we've been
watching for the past 2 years. Most of the affected seem to use publicly
treated drinking water.
Pools filled with well water appear to
be not as severely affected.
Affected pools are not as fastidiously
maintained chemically (water balance, use of Optimizer Plus, Soft Swim Assist),
as clean pools.
One of the other common issues that
virtually ALL pool owners who experience Pink Slime observe is a more regular
need to clean away "similar-looking" stuff in their homes. They notice an
increased need to clean toilet bowls, sinks, shower areas, etc. It's
appears to be the same stuff.
A second observation is that many
water companies across the country, in partial response to "consumer calls" to
"get rid of chlorine in the drinking water" are now using mono-chloramines to
treat the water (over the past 5 to 10 years). Mono-chloramines do an
essentially good job at treating pathogens in the drinking water, however, some
of the non-pathogenic organisms may indeed be getting by.
Unfortunately, we only have experiential or anecdotal evidence. Having
treated literally hundreds & thousands or swimming pools with biguanide systems
over the past 20 years, these are our observations. I don't believe we're
that far off base.

Finding Pediatric Urology In Austin?
Pediatric urology denotes the fondness of children and teens that have problems using their reproductive or urinary organs. According to the American Academy of Pediatrics (2000), a pediatric urologist has at least five years of technical training as well as four decades of medical faculty.
They have to also spend 50 percent of their professional time taking care of infants, children, and teens with urology-related conditions. You can also find out the professional pediatric urology in Austin via according to your health.
One of the many challenges associated with being a clinical pediatric urology pro is that children have an underlying difficulty communicating. When children convey their symptoms, they tend to become vague.
The information received by a physician could be confused by the interpretations of another party, such as a parent. Reports from family might be distorted due to their own fears in regards to the child's disease.
Under these conditions, the need for performing a detailed and thorough physical and analytical investigation becomes a lot more important. Once a diagnosis has been made, the function of the pediatric urologist can be either operative or clinical.
As the medical conditions and seriousness of each and every child's condition may be different. Cases of urological conditions include; problems passing urine, urinary tract infections, and structural abnormalities in birth.
Other conditions might include bedwetting and urinary tract damage from an illness or injury. A referral to a pediatric urology pro should offer parents satisfaction; it implies that the child will have use of advanced treatments, as a result of an experienced and well-educated professional.


each CDCL solver. The first strong heuristic, VSIDS (Variable State Independent Decaying Sum), has also been introduced by the Chaff solver, and with minor tweaks, has remained the strongest heuristic for many years[15].
Before we look at the heuristics, how they work and what facts about the SAT structure they exploit, it should be noted that they are usually employed in tandem with purely random selection, to balance between the needs to exploit and to explore the search space.
VSIDS works by assigning each variable a score and then picking the variable with the highest score. If there are multiple options with the same score, then the tie has to be broken somehow, but the specifics don't matter too much.
The scores are determined using a simple algorithm:
 - Start with all counters initialized to 0.
 - On conflict, increase the counter of all variables involved in the conflict by $c_{add}$.
 - Every j conflicts, decrease the counter of all variables by multiplying it with coefficient $c_{decay}$.
The values for j, $c_{add}$, and $c_{decay}$ are picked via empirical testing, and for any reasonable implementation of VSIDS, it must always hold that $0 < c_{decay} < 1$.
The original VSIDS implementation in the Chaff solver used to only increase counter of literals in the learnt clause, rather than of all involved literals, and it also decreased the counters significantly, but rarely ($c_{decay} = 0.5$, $j = 1000$). More modern implementations update more literals and decay the counters less, but more often (e.g. $c_{decay} = 0.95$, $j = 1$). This increases the cost of computing the VSIDS but makes the heuristic more responsive to changes in the current search space[16].
Over time, various different modifications of VSIDS have emerged, and I want to showcase at least one of them. The paper that introduced this modification called it adaptVSIDS[17], short for adaptative VSIDS. The idea behind it is to dynamically change the value of $c_{decay}$ depending on the quality of the learnt clauses, so that when the learnt clauses are of high quality, the solver stays in the same area of the search space for longer, and if the learnt clauses are of poor quality, it will move out of this area of the search space quicker. Specifically, it will increase $c_{decay}$ when the learnt clauses are good, and decrease it when the learnt clauses are bad, as measured by a clause-quality metric such as LBD mentioned above.
Learning Rate Based heuristics (LRB and friends)
This is a relatively new family of heuristics (~2016 onwards), with a simple motivation: the big differences between the old DPLL algorithm and the modern CDCL one is that the latter learns about the structure of the problem it is solving. Thus, optimizing variable selection towards learning more is likely to perform better in the long run.
However, while the idea is simple, implementation is much less so. Computing learning rate based heuristic boils down to solving an online reinforcement learning problem, specifically, it is the Multi-armed bandit (MAB) problem. Our MAB is also non-stationary, that is, the underlying reward (learning rate) distribution changes during play (solving the problem), which further complicates finding the solution.
In the end, the algorithm applied is in many ways similar to VSIDS, in that a variant of exponential moving average (EMA), is applied to each variable and the one with the best score is selected at each step for branching. The important difference is that while VSIDS bumps each variable involved in a conflict by a fixed amount, the LRB heuristic assigns each variable a different payoff based on the amount of learning it has led to[18].
As mentioned in the first post, solving NP-complete problems (such as SAT) naturally leads to heavy-tailed run times. To deal with this, SAT solvers frequently "restart" their search to avoid the runs that take disproportionately longer. What restarting here means is that the solver unsets all variables and starts the search using different variable assignment order.
While at first glance it might seem that restarts should be rare and become rarer as the solving has been going on for longer, so that the SAT solver can actually finish solving the problem, the trend has been towards more aggressive (frequent) restarts.
The reason why frequent restarts help solve problems faster is that while the solver does forget all current variable assignments, it does keep some information, specifically it keeps learnt clauses, effectively sampling the search space, and it keeps the last assigned truth value of each variable, assigning them the same value the next time they are picked to be assigned[19].
Let's quickly examine 4 different restart strategies.
 1. Fixed restarts
This one is simple, restart happens every n conflicts, and n does not change during the execution. This strategy is here only for completeness sake, as it has been abandoned long ago because of poor performance.
 1. Geometric restarts
This is another simple strategy, where the time between restarts increases geometrically. What this does in practice is to restart often at the start, sampling the search space, and then provide the solver enough uninterrupted time to finish the search for a solution.
 1. Luby restarts
In this strategy, the number of conflicts between 2 restarts is based on the Luby sequence. The Luby restart sequence is interesting in that it was proven to be optimal restart strategy for randomized search algorithms where the runs do not share information. While this is not true for SAT solving, Luby restarts have been quite successful anyway.
The exact description of Luby restarts is that the ith restart happens after \(\DeclareMathOperator{\Luby}{Luby} u \cdot \Luby(i)\) conflicts, where u is a constant and \(\DeclareMathOperator{\Luby}{Luby}\Luby(i)\) is defined as
\Luby(i) =
2^{k-1} & \text{if } i = 2^{k} - 1 \\
\Luby(i - 2^{k -1} + 1) & \text{if } 2^{k-1} \leq i \lt 2^{k} - 1
A less exact but more intuitive description of the Luby sequence is that all numbers in it are powers of two, and after a number is seen for the second time, the next number is twice as big. The following are the first 16 numbers in the sequence:
(1, 1, 2, 1, 1, 2, 4, 1, 1, 2, 1, 1, 2, 4, 8, 1, \ldots)
From the above, we can see that this restart strategy tends towards frequent restarts, but some runs are kept running for much longer, and there is no upper limit on the longest possible time between two restarts.
 1. Glucose restarts
Glucose restarts were popularized by the Glucose solver, and it is an extremely aggressive, dynamic restart strategy. The idea behind it is that instead of waiting for a fixed amount of conflicts, we restart when the last couple of learnt clauses are, on average, bad.
A bit more precisely, if there were at least X conflicts (and thus X learnt clauses) since the last restart, and the average LBD of the last X learnt clauses was at least K times higher than the average LBD of all learnt clauses, it is time for another restart. Parameters X and K can be tweaked to achieve different restart frequency, and they are usually kept quite small, e.g. Glucose 2.1 uses \(X = 50\) and \(K = 1.25\)[20].
So what restart strategy is the best? There only correct answer is neither because while glucose restarts have been very successful in SAT competitions, they are heavily optimized towards the handling of industrial (real world problems encoded as SAT) unsatisfiable instances at the expense of being able to find solutions to problems that are actually satisfiable. In a similar vein, the Luby restarts heavily favor finding solutions to satisfiable industrial instances, at the expense of finding solutions to problems that are unsatisfiable[21].
In practice, the current state of the art sat solvers use various hybrids of these techniques, such as switching between periods with glucose restarts and Luby restarts, where the lengths of the periods increase geometrically, or switching between glucose restarts and running without any restarts, and so on. There have also been some experiments with using machine learning to learn a restart strategy.
Preprocessing and Inprocessing
The last (but not least) trick I want to cover is preprocessing, and inprocessing of the input SAT instance. The motivation for preprocessing is quite simple: the provided encoding of the problem is often less than optimal. No matter the reasons for this, the end result is the same, modern state of the art SAT solvers use various preprocessing and inprocessing techniques.
The difference between preprocessing and inprocessing is straightforward. Preprocessing happens once, before the actual solving starts. Inprocessing occurs more than once because it is interleaved with the actual solving. While it is harder to implement inprocessing than preprocessing, using inprocessing carries 2 advantages:
 - The solver does not have to pay the full processing cost at the start if the problem is easy
 - Learnt clauses can be processed as well
There are too many processing techniques to show them all, so in the interest of keeping

Cows get tracking collars as scientists try to work out how they make friends
By Mark Prigg
How cows make friends is to be investigated in a bizarre three-year study.
Scientists want to understand more about'social networking' within dairy herds.
The aim is to help farmers improve the health and welfare of their cows, thereby increasing milk yields.
Social animals: Researchers hope to find out how cows interact with each other and form social groups using tracking collars
For the first stage of the research, high-tech 'proximity collar's' have been fitted to cows on a farm in Cullompton, Devon.
The collars use radio signals to determine how close one cow is to another, allowing scientists to map the animals' social interactions.
Study leader Dr Darren Croft, from the University of Exeter's Animal Behaviour Research Group, said: 'Emerging evidence on wild animal populations supports the idea that the group structure and relationships between the animals affect their health and wellbeing.
'Cows are social animals that form important group structures, and the addition or removal of animals from an established group can significantly alter its dynamics.
'We want to find out just how important these group structures are.
'Dairy farmers take a range of factors into account when deciding how to structure groups of cows.
'We hope that the results of our study may contribute towards a blueprint for herd management that will help farmers continue to improve the health and welfare of their cows.'
Researcher Natasha Boyland, another member of the Exeter team, said: 'We will look at the nature of the interactions to see just how relationships are formed and maintained within the herd.
Animals in the study will wear a special collar to track their movements around fields
'In combination with the proximity data findings and other information about the animals, such as their health status, we hope to gather evidence that can be translated into practical advice for farmers when it comes to herd management.'
The study is funded by the Department for Environment, Food and Rural Affairs (Defra) and DairyCo, the levy-funded organisation that works on behalf of British dairy farmers.
Researchers know cows are extremely social animals, and now hope to find out how they make friends and how their social groups operate in a bid to improve farming techniques
Amanda Ball, head of communications at DairyCo, said: 'This study could help dairy farmers understand more about their cows, improve their health and welfare and may even contribute towards helping to secure the future supply of milk to consumers.
'The dairy industry is worth £8 billion a year to the UK economy and it is important to support research that can help farmers continue to provide consumers with top quality dairy products whilst putting the health and welfare of their cows first.'

Palinopsia (Greek: palin for "again" and opsia for "seeing") is a visual disturbance defined as the persistent or recurrence of a visual image after the stimulus has been removed.[1] Palinopsia is not a diagnosis, but a broad term that describes a heterogeneous group of pathological visual symptoms with a wide variety of etiologies. Visual perseveration is synonymous with palinopsia.
In 2014, Gersztenkorn and Lee comprehensively reviewed all cases of palinopsia in the literature and subdivided it into two clinically relevant groups: illusory palinopsia and hallucinatory palinopsia.[2] Hallucinatory palinopsia, usually due to seizures or posterior cortical lesions, describes afterimages that are formed, long-lasting, and high resolution. Illusory palinopsia, usually due to migraines, head trauma, prescription drugs, or hallucinogen persisting perception disorder (HPPD), describes afterimages that are affected by ambient light and motion and are unformed, indistinct, or low resolution.
Differentiation from physiological afterimages[edit]
Palinopsia is a pathological symptom and should be distinguished from physiological afterimages, a common and benign phenomenon.[1][3][4] Physiological afterimages appear when viewing a bright stimulus and shifting visual focus. For example, after staring at a computer screen and looking away, a vague afterimage of the screen remains in the visual field. A stimulus consistently produces the same afterimage, which is dependent on the stimulus intensity and contrast, the time of fixation, and the retinal adaptation state. Physiological afterimages are usually the complementary color of the original stimulus (negative afterimage), while palinoptic afterimages are usually the same color as the original stimulus (positive afterimage). There is some ambiguity between illusory palinopsia and physiological afterimages since there are not concrete symptomatic criteria which determines if an afterimage is pathological.
Illusory vs Hallucinatory[edit]
For more details on this topic, see Illusory palinopsia and Hallucinatory palinopsia.
Illusory palinopsia is due to an abnormality in the original perception of a stimulus and is similar to a visual illusion: the distorted perception of a real external stimulus. Hallucinatory palinopsia is due to an abnormality after a stimulus has been encoded in visual memory and is similar to a complex visual hallucination: the creation of a formed visual image where none exists.
External conditions such as stimulus intensity, background contrast, fixation, and movement typically affect the generation and severity of illusory palinopsia but not hallucinatory palinopsia. Illusory palinopsia consists of afterimages that are short-lived or unformed, occur in the same location in the visual field as the original stimulus, and are continuous or predictable. Hallucinatory palinopsia describes formed afterimages and scenes that are life-like, high-resolution, long-lasting, occur anywhere in the visual field, and are unpredictable. Illusory palinopsia are caused by diffuse neuronal pathology such as global alterations in neurotransmitter receptors, while hallucinatory palinopsia is typically caused by focal cortical pathology.
The clinical characteristics that separate illusory from hallucinatory palinopsia also help differentiate and assess risk in visual illusions and hallucinations. Complex (formed) visual hallucinations are more worrisome than simple visual hallucinations or visual illusions.
Associated symptoms[edit]
People with palinopsia frequently report other visual illusions and hallucinations such as photopsias, dysmetropsia i.e. Alice in Wonderland syndrome (micropsia, macropsia, teleopsia, and pelopsia), visual snow, oscillopsia, entoptic phenomena, and cerebral polyopia.
Etiology and pathophysiology[edit]
For more details on this topic, see Hallucinatory Palinopsia and Illusory Palinopsia.
Posterior visual pathway cortical lesions (tumor,[1] abscess,[3] hemorrhage,[5] infarction,[1] arteriovenous malformation,[6] cortical dysplasia,[7] aneurysm[1]) and various seizure etiologies (hyperglycemia,[8] ion channel mutations,[9] Creutzfeldt-Jakob Disease,[10] idiopathic seizures,[11] etc.) cause focal cortical hyperactivity or hyperexcitability, resulting in inappropriate, persistent activation of a visual memory circuit.
Illusory palinopsia is a dysfunction of visual perception, resulting from diffuse, persistent alterations in neuronal excitability that affect physiological mechanisms of light or motion perception. Illusory palinopsia is caused by migraines, HPPD, prescription drugs, head trauma, or may be idiopathic. Trazodone,[12] nefazodone,[13] mirtazepine,[14] topiramate,[15] clomiphene,[16] oral contraceptives, and risperidone[17] have been reported to cause illusory palinopsia. A patient frequently has multiple types of illusory palinopsia, which represent dysfunctions in both light and motion perception. Light and motion are processed via different pathways, suggesting diffuse or global excitability alterations.
Future research[edit]
Research needs to be performed on the efficacy of the various pharmaceuticals for treating illusory palinopsia. It is unclear if the symptoms' natural history and treatment are influenced by the etiology. It is also not clear if there is treatment efficacy overlap for illusory palinopsia and the other co-existing diffuse persistent illusory phenomenon such as visual snow, oscillopsia, dysmetropsia, and halos.[2]
Future advancements in fMRI could potentially further our understanding of hallucinatory palinopsia and visual memory. Increased accuracy in fMRI might also allow for the observation of subtle metabolic or perfusional changes in illusory palinopsia, without the use of ionizing radiation present in CT scans and radioactive isotopes. Studying the psychophysics of light and motion perception could advance our understanding of illusory palinopsia, and vice versa. For example, incorporating patients with visual trailing into motion perception studies could advance our understanding of the mechanisms of visual stability and motion suppression during eye movements (e.g. saccadic suppression).

Customer Satisfaction Lies Somewhere Between Pleasure And Pain
May 3, 2012
A new paper by Kyle Murray, a marketing researcher with the Alberta School of Business, puts a spin on the expression "you can't please everyone."
The pleasure-versus-pain principle
The researchers studied people's reactions to two consumer experiences: tasting a cup of coffee and choosing a digital camera. In both studies, there was a quality product and one that had been altered to affect its quality. Test subjects were asked to rate their satisfaction with the product's quality. The researchers discovered that respondents fell into two categories: promotion-focused (pleasure-seeking) or prevention-focused (pain-avoiding). "These two types of people respond very differently to having the same kind of service encounter or having the same kind of problem with a product," said Murray.
"People who are promotion-focused tend to get a lot more hurt when something goes wrong, but they're also a lot happier when something goes right," he said. "The prevention-focused people are less upset when something goes wrong–when they buy a product and it breaks or they have a bad service experience–but they're also less happy when something goes right."
Can't get no satisfaction? It may be a conservative bias
Murray notes that although the prevention-focused response was far less extreme than the promotion-focused response, the pain-avoiding group appeared less able to enjoy a positive consumer experience. As a consequence, their controlled reactions left them feeling less joy when something went right–a phenomenon the researchers labelled a conservative bias.
"That conservative bias changes the way they see the world," he said. "They're a little bit more constrained in all their responses, at least in the realm of satisfaction."
Get to know consumer audiences
Prior research suggests that there is segmentation across both gender and age lines. Specifically, previous work indicates that women and older adults are slightly more chronically prevention-focused, whereas men and younger people tend to be more promotion-focused. Murray says that changing our consumer characteristics may not be an option, but being able to understand how the other side responds certainly is. For the customer service world, this means helping staff to understand both groups, and preparing them for the reality that when it comes to complaints, one style does not fit all.
"To some extent, they can tell front-line people that, as older people approach them, they're going to be more prevention-focused, they're not going to be as extreme either way," said Murray. "But when something has gone really wrong with that 21-year-old's game console, they're going to be a lot more upset and more likely to tell their friends.
"On the flip side, when they take it home and it works well and they really enjoy it, they're more excited and happy, and more likely to tell their friends about it."

Formative Assessment, Homework, Self-regulation
This study explored the formative learning cycle's ability to increase student confidence to create quality homework. Student from a socio-economically diverse school district in Western Pennsylvania reported their confidence levels on homework production on two surveys. The first survey provided a rapid response at the end of lessons taught using the formative learning cycle. The second survey was completed at the end of the study window. The results from these surveys indicate a positive correlation between the formative learning cycle's ability to increase self-regulation processes to confidently produce quality homework.

Athabasca Landing Exploratory Borehole Project
The Athabasca Landing tar sands borehole project that started in 1894 broke ground on the 1st of August, drilling to a final depth of 1731ft in 1896. And considered one of the oldest wells in Alberta.
During the month of February of 2021, only 125 years later, drilling has once again returned to the borehole, only this time with different intention. The Alberta Energy Regulator (AER) has adopted the responsibility of properly abandoning and putting the exploratory borehole to rest. Titanium Energy Services, based out of Lloydminster Alberta had been chosen by Codeco-Vanoco Engineering Inc. as the primary service for the project. Due to the geographical difficulties and environmental concerns with the well's extremely close proximity to the Athabasca River, coiled tubing was the operational means chosen to abandon the borehole. The coiled tubing unit application would provide the service required, as well as providing the smallest environmental footprint. The surroundings of the well could remain mostly undeveloped and in their natural state as equipment would not need immediate access to the well.
Parked next to the CTU was a 275T crane to lift the injector head over the riverbank and nipple on to the well. The primary goal was to mill down as deep as possible, set a permanent bridge plug in what casing remained then spot a cement plug on top to seal off any natural gas from migrating to the surface. Drilling would be conducted using a 2 7/8'' mud motor with a tri cone drill bit or a tapered mill on the end. Fluid pumped through the coil tubing using Titanium's fluid pumping unit would turn the bottom of the motor attached to the coil end which would in turn rotate the drill bit. The rotating drill bit would allow the coil tubing to travel down the casing as it chewed through shale and other borehole solids encountered years ago. Preparations were made around the borehole to ensure worker safety during operations. Wood and steel rig matting were placed around the borehole as work platforms, along with a temporary staircase down the riverbank for access.
Well Abandonment Project
On March 1st work commenced to mate modern well head flanges to the 7 ½'' casing that protruded from the ground allowing for an orbital valve and blow out preventer to be installed as a secondary precaution for containing gas and well bore fluid. Blow out preventers (BOP) can weigh a considerable amount, so a bracing structure was manufactured onsite to absorb and remove the weight from the aged well. With BOP in place the coil tubing injector was installed onto the well, fresh water was pumped through the coiled tubing that that initiated the rotation of the mud motor. At 2.5ft below ground level the 4.875'' mill tagged an obstruction. Mud, sticks, and gravel was noted at the return tank on top of the riverbank as fluid was pushed up the hill through metal line piping from the well. After 30 mins of drilling only 0.5ft of hole was made. It was decided to shut down pumping operations investigate the impediment. Operations were suspended for the night as new approaches were to be considered by Codeco-Vanoco Engineering Inc..
On the morning of the 2nd a decision had been made from the results of their analysis. A smaller tri-cone bit would be installed on the mud motor and soon after drilling commenced it seemed the drill bit was doing its job. Drilling seemed to be progressing well, however, at 164ft fluid returns at the return tank ceased. This posed a cause for concern as it was clear something had changed down hole. Further analysis of the operation uncovered that the 3 5/8'' casing had disappeared. Operations were suspended for the day as new approaches were to be discussed and considered.
Athabasca Landing
The following day it was decided to do away with the drilling assembly and try a less abrasive approach. A 3.5'' ported nozzle was installed on the coil end with the purpose of pumping water through to clean out to the depth of 213 achieved the prior day.
A Titanium Wireline logging unit had been summoned to location to provide further insight into the downhole dilemma. The wireline logging unit lowered a gamma ray CCL tool to analyze on how far the 7 ½'' casing protruding from the riverbank extended. The wireline professional notice an obstruction tagged at 88.5ft. The wireline was pulled to surface while logging its scan of the wellbore discovered that the 7 ½'' casing penetrated the riverbank to 36ft, which coincided with the 1894 drilling report. Beyond that was clearly open hole. Operations were shut down for the day as decisions on how to proceed were discussed.
The Alberta Energy Regulator decided to proceed with pumping cement into the borehole following an engineered plan to seal off any gas or fluids from migrating to surface. Titanium Coil Tubing Unit swept in and out of hole while pumping fluid to clean up with open hole of debris. Once the cementing units had arrived, liquid cement was pumped through the coiled tubing followed by fresh water to push the cement through the coil and out of the nozzle tip. The coil and nozzle were positioned at the bottom to ensure cement was placed at the deepest depth achieved. With cement flowing out of the nozzle tip the injector slowly pulled the coil tubing towards surface. When coil had arrived at surface all the cement had effectively been flushed out of the tubing. It was noted that liquid cement had made its way up and around the outside of the 7 ½'' casing. This was good news as it would perhaps add some stability and offer a seal from possible fluid and gas migration. The cement would take approximately 12 hours to fully solidify, so operations were suspended for the day.
Returning to site it was discovered that the cement was proving to do what was intended. Any noticeable seeping of gas up the 7 ½'' casing during the operation had ceased. The well would now be monitored over the following years to ensure that this remained the case. The exploratory borehole then and now had proved to be a challenging undertaking. The monitoring of the well over the coming years will tell us whether the Athabasca Landing exploration hole has seen its last day of drilling.


How to Find Balance Between Talking the Talk and Walking the Walk as Digital Marketer
Digital marketing is a business that includes learning, talking and doing.
Each one of these aspects has importance. You can't get far without networking, constant learning or actually working on your marketing. However, these three activities must be in the correct proportions.
Finding the golden ratio between them is not so easy, as we tend to emphasize one aspect of marketing according to our personal predisposition. I will now explain the three traps of imbalanced digital marketing and how to find the balance between those activities.
Trap 1: Too much talking
Talking, sharing ideas and networking is important, but it can get out of hand sometimes. When I started my digital marketing career, I tended to talk too much about it. A lot of my friends believed that trying to make money from monetizing blog traffic or affiliating is doomed to failure. They were missing out on a lot of opportunities. I felt like I had to help them and teach them everything I knew.
Maybe I helped some of them and made a few connections along the way. However, the benefits I got from sharing, in terms of good ideas and networking, were minimal in comparison to the loss in motivation and waste of energy. So there are times when it's better to focus on doing and learning.
Trap 2: Too much learning
Learning a lot can also be a great way to be ineffective in marketing. I have a developer friend who is a genius in his field. He can write a Ph.D. about every little aspect of server management and email client installation and stuff that is all Chinese to me.
Well, he got fired a year ago and is still struggling to find work. His problem is that he is obsessive about learning. A task that would take another system developer an hour takes him a day, since he can't proceed without learning everything and testing all the features and options. Digital marketers can fall into this as well.
Every day there are new tools and features launched, new trends and marketing channels, new networks and marketing strategies. I often get caught knowing much more than doing. Digital knowledge that you don't use immediately can easily become a waste of time since it might be irrelevant by the time you need it.
Trap 3: Too much doing
Then there are the doing-type people who just do and do without knowing enough what they are doing. It seems like it would be hard to be too active and committed, but often this "get it done" attitude means a lack of flexibility or common sense. I know natural doers who wasted months of work on strategies that were not effective and even harmful.
The golden mean / How to find balance
The golden mean or golden middle way is the path between two extremes. It's not a static thing. At times, you should study a lot and upgrade your understanding, like when doing SEO in the middle of a big Google update. At other times, you should network and investigate, like when you can't find any strategy to really breakthrough your campaigns.
But more often or not, doing is the major factor. I would say that studying and talking for a day in a week and working for four days is a good ratio in most cases. Personal capacities and predispositions affect this formula.
A quick doer should invest more time in studying, while a fast learner should invest more in doing. Exactly how to find a balance between these factors changes all the time. Be attentive and sincere with yourself, and you will find the perfect proportion for you.

What is the solid surface wash basin?
The wash basin is one of the indispensable sanitary wares in our living bathroom, because the wash basin is often used in our lives.It also known by other names including sinker, washbowl, hand basin, and wash basin—is a bowl-shaped plumbing fixture used for washing handsdishwashing, and other purposes. There are many material for wash basin,So choose a wash basin that fits the style and good material of the bathroom are very important. lets introduce KKR solid surface material wash basin for you.
Solid surface wash basin may be growing in popularity as people choose them over higher priced sink options. There are six reasons a homeowner may choose a solid surface sink.
Scratch Resistant
While solid surface wash basins can get scratched, the scratches can be removed if they are buffed with a non-abrasive scrubbing pad. Most minor cigarette burns can also be removed with gentle sanding.
Seamless Appearance
KKR wash basin/sinks can have a smooth feeling and may also have a seamless appearance. This smooth texture and the invisible seams can protect small particles like dirt crumbs and bacteria from collecting. The seamless surface can also provide a water-tight seal and can eliminate the need for caulk.
Unlike standard recessed sinks that can increase the likelihood of bacterial growth in the rimmed edges, solid surface sinks may not have these. Their nonporous surface may also have antimicrobial properties that can prevent the growth of mold, mildew and bacteria. This can be especially beneficial when these sinks are used in food preparation areas like kitchens.
Stain Resistant
Accidental spills can happen and when they do, the results can be permanent. The material in a solid surface sink can resist the permanency of these stains. Most marks or stains left from lipstick, marking pens, juice, dyes or makeup can be removed with a non-abrasive scrubbing pad.
Solid surface basins can come in a variety of colors and patterns. Some may have patterns that look like granite and others may have whimsical colors and patterns to match a more eclectic decor. These color patterns can be visible throughout the entire depth of the material, rather than just on the surface, and the material can be made to fit a variety of shapes.
Less Maintenance
In most instances, KKR solid surface basin can be cleaned with soapy water and a non-abrasive cloth.Its very easy to clean.
 In addition, I would like to add that if it is practical and convenient, I think that in terms of material, you should choose the wash basin of solid surface stone. Because the acrylic solid surface stone wash basin is easy to maintain and can be polished repeatedly when Be scratched.

Rapid Pest Risk Analysis Xyleborinus attenuatus
This rapid pest risk analysis (PRA) provides a quick assessment of the risks posed by the pest to Sweden, which is the PRA area being assessed. The format is an adapted version of the EPPO Express PRA scheme (EPPO 2012). Definition ofterms used as well as the rating scheme and assessments are done in line with the guidance given in the EPPO CAPRA system (EPPO 2011). The likelihood of entry and establishment are assessed considering the current phytosanitary regulation in place with respect to the EU legislation (Council Directive 2000/29/EC). The definition of a quarantine pest follows the regulation (EU) 2016/2031.
Xyleborinus attenuatus is established in Sweden. The ambrosia beetle originates from Japan and eastern Russia and has until now spread to 13 European countries as well as to USA and Canada.
Entry, establishment and spread
The likelihood of entry of Xyleborinus attenuatus into Sweden is assessed to be very likely. The main pathways of entry are "Wood and wood products" and "Natural spread". X. attenuatus is already established and further spread is assessed to be very likely since suitable host are widely distributed in Sweden, the climate is suitable and the species have a track record of being able to establish in different environments. The rate of spread is assessed to be high based on the species presumed high flight capacity and the high likelihood of spread through transportation of colonized wood material.
Both the economic, environmental and social impact was assessed to be small since there currently is little support in the easily accessible literature that the pest cause significant damage. Nevertheless, there is a risk for a similar shift towards increased impact as have been recorded for closely related ambrosia beetle species.
Management options
It is assessed to be difficult to prevent further introductions of X. attenuatus to Sweden. Current phytosanitary measures such as barking and heat treatment does not completely prevent entry of ambrosia beetles with wood and there is also a risk of natural spread from Denmark.
Assessment in relation to the definition of quarantine pests
The results presented in this rapid PRA shows that Xyleborinus attenuatus does not fulfil all of the criteria for a union quarantine pest, e.g. it is widely distributedwithin the EU territory. In addition, it indicates that X. attenuatus does not fulfil allcriteria for a protected zone quarantine pest for any part of Sweden, e.g. due tolimited possibilities to prevent natural spread from areas where the pest isestablished and that the impact was assessed to be small.
Key uncertainties and further investigation needed
There is a large uncertainty in the assessment of the future impact of Xyleborinus attenuatus due to the potential risk that it may shift from colonizing dead trees to colonizing live trees as has been observed for other closely related beetle-fungus symbioses (Hulcr and Dunn 2011). It would therefore be desirable if the development of X. attenuatus, both nationally and internationally, is followed to detect any shift towards increased impact.

At the beginning of Chinese history stands a tablet which in some mysterious way is supposed to be connected with an explanation of the universe. It has been reconstructed by later Chinese thinkers and is pictured in the hands of Fuh-Hi as an arrangement of the kwa figures preserved in the Yih King. Considering the several traces of Babylonian traditions in ancient Chinese literature and folklore, would it not be justifiable to identify the tablet of Fuh-Hi with the ancient Babylonian "Tablet of Destiny" mentioned in the Enmeduranki Text, a copy of which was discovered in the archives of Asurbanipal 20 and was said to contain the "Mystery of Heaven and Earth?"
p. 34
Enmeduranki, king of Sippar, is the seventh of the aboriginal kings, and he declares that he received the divine tablet "from Anu, [Bel, and Ea]." 21
Chinese sages have their own interpretation of the phrase "the mystery of heaven and earth." They would at once associate the words "heaven" and "earth" with the two opposing principles yang and yin, and the question is whether among the ancient Sumerians there was not a similar tendency prevalent. It seems to be not impossible that the Chinese tablet in the hands of Fuh-Hi is the same as the "Tablet of Destiny" of the Sumerians, and when some Assyriologist has informed himself of the primitive Chinese conception of this mysterious tablet, he may be able to throw some additional light on the subject.

* The "absolute nuclear" family type is both liberal and unequal. Children are totally emancipated, forming independent families of their own. The inheritance usually goes to one child, often a son.
* The "egalitarian nuclear" family type is both liberal and equal. Children are as emancipated and independent as in the previous type, but equal division of the inheritance encourages stronger parent-children relations before the passing of the parents.
* The "stem" family type is both authoritarian and unequal. Several generations live under one roof, with one child marrying to continue the line. The other children remain unmarried at home, or leave to get married.
* The "incomplete stem" family is as above, but with slightly more equal inheritance rules — an intermediate with the last family type.
* The "communitarian" family is both authoritarian and equal. All sons can marry and bring their wives into the ancestral home. The family inheritance is divided equitably among all children.
Is there a connection between family-inheritance type and fertility in today's Europe? Have a look:
[Map from Eurostat]
How does "family type" affect fertility?
I have a hard time seeing seeing any strong correlation. More precise data would help. Certainly other factors seem more important, political, cultural, economic. German fertility is low across the board, across two family-type zones. Nevertheless, other 'Stem Family' regions have more robust fertility. Germans are clearly still very nationally — perhaps better-to-say 'civilizationally' — pessimistic, a legacy of defeat decades ago and demonization ever since.
A more suitable question would be, "all else equal, how does 'family-type' affect fertility?" Inheritance is a major part of this 'family-type' concept, and the question of inheritance and fertility was first brought to my attention by the commenter Rollory in a post about France's low-fertility 1800s.
A casual analysis: Looking at Netherlands alone (all are part of Dutch culture), it seems Absolute Nuclear regions out-breed Stem Family regions. The highest-fertility department in France seems to be mostly Absolute Nuclear. The highest-fertility region of Scotland is Absolute Nuclear.
Why would "Absolute Nuclear" produce highest fertility?


How long is the Arizona Trail?
The current official length of the Arizona Trail is 788 miles, not counting side trails and summit routes to off-trail scenic overlooks. The trail may be rerouted each year due to wildfires, blowdowns, flooding, or other natural obstacles. The trail is subdivided into 43 passages or sections.
Where does The Arizona Trail begin and end?
The most popular route for the AZT is Northbound (known as NOBO), beginning at the U.S/Mexico border at a monument in In Coronado National Memorial near the Huachuca Mountains and ending at the Utah border on Buckskin Mountain. Hikers generally begin in late February or early March. Our team will hike Southbound (SOBO), beginning September 27th and ending in November 2020.
How many days will it take to complete the hike?
It generally takes a thru-hiker 6 to 8 weeks to complete the Arizona Trail. We are aiming for 45-50 days, weather and health permitting.
How many people thru-hike the AZT each year?
Roughly 100 people thru-hike the Arizona Trail each year. Many others complete various sections from the list of 43 passages; some piecing together the entire trail over many years of section-hiking.
How will you access and carry water?
We will each carry roughly 1 liter of water per 4 miles we plan to hike each day between water caches, streams, wildlife ponds, and cattle tanks strewn across Arizona. Although we always prefer fresh water supplied by our support team, there will be many times where it is necessary to filter water from wild sources. Our longest scheduled water carry is about 30 miles between water sources. We will have the capacity to carry up to 9 liters each. Each liter of water weighs 2.2 pounds! Our average water carry will be 3-5 liters each.
Where will you be sleeping?
We will each carry our own tent and will sleep most nights under the stars along the trail. There are a few "gateway communities" and towns along the way where we may stay in hotels, hostiles, or with friends.
How will you handle dangerous wildlife encounters?
Animals are more afraid of humans than we are of them. In Arizona, we will encounter scorpions, rattlesnakes, Gila monsters, coyotes, and possibly black bear, bobcats, and mountain lions. Our guide is experienced dealing with wildlife and will help us navigate and even enjoy these encounters.
How will you communicate in case of emergency?
We are carrying cell phones, satellite GPS two-way communicators, and a personal locator beacon (PLB) in case of emergency. Although the trail is remote and non-motorized, we will usually be within about a few hours from an extraction point if needed.
What if you get lost?
We are carrying GPS apps and a map and compass. Our guide is highly experienced with wilderness navigation.
Why did you select the Arizona Trail?
Arizona is our home. Of the 11 National Scenic Trails contained within the National Trails System, it makes the most sense for us to complete the AZT since our goal is to raise $1,000,000 to bring hope and healing to the people of Colorado City, AZ.

Higher reliability. Improved mixing efficiency. Increased duration.
Pressure leaching 'severe service' challenges:
- scale formation
- corrosion (acidic environment)
- wear and erosion
- high velocity and 3-phase flow
- high oxygen concentration
- thermal shock
Specific to the autoclave industry, MOGAS has directly employed and strategically partnered with the best technical specialists, who support the start-up and ramp up to full production of high-pressure acid leach (HPAL) and pressure oxidation (POx) production plants globally.
These experienced operational and maintenance personnel have solid process understanding—a critical factor in the successful start-up of a high-pressure metallurgy process in an autoclave-based circuit, compared to a conventional atmospheric leach or concentrator plant.
This experience base provides input and a better understanding of the overall process circuit beyond autoclaves that advance valve and system designs specific to customer requirements. MOGAS can assess specific design aspects of the circuit to not only assimilate the current operational procedures, but to the underlying reasons for the way the procedures were developed—the 'why's' to procedural steps, operational sequences or specific design features.
The majority of all autoclaves worldwide use MOGAS severe service technology.

Low-Power Liquid Lens
October 1, 2008
Droplet optics: This series of pictures shows droplets of water in a hollow Teflon cylinder every four milliseconds. The curved shape of the water forms a lens, which changes shape, and therefore focal length, when sound waves are applied to one side of the cylinder.
Finding focus: These three pictures were taken, from left to right, after 0.007, 0.020, and 0.033 seconds. The focal point of the lens changes as the sound waves alter the shape of the droplet. The researchers suggest that a camera using this liquid lens could take tens of pictures at the press of a button and let software sort out the one that's most in focus.
In tests, Hirsa's liquid-lens camera was able to take 250 images per second, at varying focal lengths. He envisions a camera that could instantly capture tens of images with different focal lengths, and then use simple image-analysis software to determine the most in-focus image. "Say you capture 60 frames per second," he says. "Just take the one that's the sharpest."
Stein Kuiper, the Philips researcher who developed the electrowetting technique, notes that the researchers' ideas seem original, but he sees drawbacks to the approach. Since the lens is continuously moving, this means that "a significant amount of light is lost, as most of the time the object is out of focus."
Additionally, these early results are not high resolution, notes Yuhwa Lo, a professor of electrical engineering at the University of California, San Diego. "Even the low-end cameras have a pretty strict resolution requirement," he says. However, he says that at this stage, the lens could be good for other optical applications, such as simply focusing beams of light instead of taking high-quality pictures.
Hirsa says that his team is looking to improve the resolution, possibly with different types of fluid, such as those that change shape in response to magnetic fields. He's also exploring the possibility of working with electronics manufacturers and says that Samsung has expressed interest in the lens.

Hawaii has their own unique holidays aside from remembering the United Sates holidays. The three holidays are the Prince Jonah Kuhio Kalanianaole Day, Admissions Day, and King Kamehameha I day. In these events, you cannot make any transaction to the banks and other offices.
However, aside from these events, there are also other Hawaii Holidays. Like for instance, the May Day, Chinese New Year, the Boy's Day, and the Girl's day. Below are the overview of the various Hawaiian Holidays:
The First event is the Prince Kalanianaole Day and it is also called as Kuhio Day. Usually it happens even March 26th. This is in honor to the Prince. He is loved by people because he was able to get the land from the congress and distribute it to the Hawaiian families. During the event, there will be a parade on the island plus with the canoe races.
Vacations – Getting Started & Next Steps
The second one is the King Kamehameha I day which is also called Kamehameha day.
Vacations: 10 Mistakes that Most People Make
It is celebrated every year on June 11th. He is recognized for uniting the Hawaiian Islands and he was also the first ruler.
There will be parades, festival, as well as the covering of the king's statue with flowers.
There is also the Admissions Day and it is also called "Statehood Day." It happens every 3rd Friday of August because it reminds how Hawaii has become the one of the states of America.
One of the holidays in Hawaii is the May Day or also called as the Lei Day. It is held on the first week of May. It is to have fun for the creation as well as the use of the flower lei. People will wear leis and they will have the parade. Children usually love this day as they participate.
Tango no Sekku is another term for the Boy's Day. It is really a Japanese occasion which was influenced to the Hawaiians. It is held on the May 5th. Each of the families would put large koi fish on the bamboo in their houses. The number of carp that will be hanged will be based on how many the boys are in the family. The reason behind this is that the fish will symbolize strength and power. The people believe that their boys will become courageous and responsible if they will follow this ritual.
The girl's day in Hawaii is also called as Matsuri. Like the boy's day, it is also influenced by the Japanese. It is observed on March 3rd.
Hawaii also celebrated Chinese New Year. The people usually meet each other during this event.
This is event was brought by the Chinese immigrants. Usually, the people will have tea ceremonies, fireworks, parades, and dragon dances.
You will enjoy each of these holidays, so, you better check out for cheap Hawaii Holidays deal.

Method for broadband spectroscopy of light transport through opaque scattering media
We present a broadband technique for the measurement of diffuse light transport through opaque scattering media. Using the spectral correlations introduced by a scattering medium onto a white-light supercontinuum spectrum, the diffusion constant of light is determined over a wide spectral range in the visible and the near IR. Independent broadband measurements of both the transport mean free path and the diffusion constant are used to calculate the spectral dependence of the energy velocity in a porous GaP slab. Broadband correlation spectroscopy is found to be an excellent tool for the characterization of random scattering media.

I'm tickled to see that my work on stonefly flight has come up in this discussion. One thing that is worth adding here is that a gills-to-wings transition would require a simultaneous change in gas exchange, since a sophisticated wing is unlikely to also be an effective gill, and the physics and physiology of gas exchange are very different in an aquatic versus a terrestrial environment. My research shows that modern stoneflies may have retained intermediate forms of flight that date back to an evolutionary transition from gills to wings, and therefore perhaps they have retained other traits related to a transition in gas exchange physiology. This line of thinking led me to suggest to Thorsten Burmester, an expert on arthropod gas exchange proteins, that he should check to see if stoneflies have hemocyanin in their blood. This was a pretty far out idea, since blood-based gas exchange is what other arthropods use (including aquatic ones) but was previously thought to be completely absent in insects, which deliver air directly to their tissues via tracheae. Burmester found that stoneflies do indeed have hemocyanin in their blood (Proceedings of the National Academy of Sciences 101: 871-874) that reversibly binds oxygen, and it appears that no other pterygote insects possess this trait. In summary, the developmental evidence that you have presented for a gills-to-wings transition is supported by both a set of mechanically intermediate forms of winged locomotion in stoneflies and molecular evidence that a simultaneous transition occurred in gas exchange physiology.
