The role of the skin on our fingertips, palm and soles of the feet is to grip other objects, and they all have characteristic "friction" ridges. Nevertheless, very little research has been carried out about how well fingers perform, how friction is achieved and why we have soft fingerpads with fingerprints at all. Recent research carried out in the laboratory of the University of Manchester suggests that finger skin has frictional properties rather like rubber.
|Why do we have fingerprints?
The most likely possible answers are:
1) Fingerprints may increase friction on rough materials;
New British research indicates that the first option can be deleted from the list. Researcher Dr. Roland Ennos explains his findings below:
"I have been thinking about this for years and, having played around with it for a bit, realised that skin is rubbery so the ridges in fingerprints might actually reduce grip.
Our experiments – using a plastic cup, weights and strips of Perspex (acrylic glass) to develop a simple machine in the lab – proved me right.
The experiment was so simple, this discovery could have been made 100 years ago; but scientists make assumptions and tend to look at complicated things instead.
We are now testing that theory and two others, that fingerprints improve grip on rough surfaces and that they increase sensitivity.
There are potential spin-offs for this work. For example some people who suffer nerve damage that prevents sweating have slippery fingers and cannot grip: we could develop something to treat that."

Quick Answer: Is It Correct To Be More Busy?
Is Unbusy a word?
Yes, unbusy is in the scrabble dictionary..
What is the superlative of beautiful?
beautiful (comparative more beautiful, superlative most beautiful)
Why is more better wrong?
"More" implies a higher level of "good." Therefore, "more better" would imply a level that is better than better. "More better" is never correct. If you want to say that something is better than good, you say it is "better," but if you want to say it is more than better, you say that it is "best."
What is the meaning of busy?
Adjective. busy, industrious, diligent, assiduous, sedulous mean actively engaged or occupied. busy chiefly stresses activity as opposed to idleness or leisure. too busy to spend time with the children industrious implies characteristic or habitual devotion to work.
What is the meaning of less?
1 : constituting a more limited number or amount less than three less than half done. 2 : of lower rank, degree, or importance no less a person than the president himself. 3a : of reduced size, extent, or degree. b : more limited in quantity in less time.
What's another word for busy?
What is the degree of busy?
busier. Superlative. busiest. The superlative form of busy; most busy.
Is busy an abstract noun?

Fix a set $ \Gamma\subset \mathbb F_p$, the field with $p$ elements and a parameter $\epsilon>0$. The Bohr set $B(\Gamma,\epsilon)$ consists of those $x$ for which $x\cdot \Gamma\subseteq[-\epsilon p,\epsilon p]$ - I am identifying the interval with its image mod $p$. The standard lower bound for $B(\Gamma,\epsilon)$ is then $\epsilon^{|\Gamma|}p$ (which is given by the pigeon-hole principle) and this is in fact what one expects (more or less since one expects the events $x\gamma\in[-\epsilon p,\epsilon p]$ with $\gamma\in\Gamma$ to be independent trials). Since $\Gamma\subset B(B(\Gamma,\epsilon),\epsilon)$, this lower bound can miss the mark. What I want to know is if there is something about $\Gamma$ that will tell me it should have the expected size.
EDIT: I have figured out some estimates in the case that $\Gamma$ is dissociated, see below. I am wondering if one can do better in this case, or if one can be more general.

1 Answer 1
To some extent one can obtain upper bounds on $B(\Gamma,\epsilon)$ when $\Gamma$ is quite special. For instance, when $\Gamma$ is dissociated (which is to say, the sums $\sum_{s\in S}s$ are distinct for each $S\subset \Gamma$) then one can say something. Indeed, any dissociated set of size $d$ cannot be contained in an interval of size $\epsilon p$ if $2^d\geq d\epsilon p$ which shows that if $\epsilon< 2^d/dp$, then $B(\Gamma,\epsilon)$ consists only of the zero element. From this one can obtain bounds for larger $\epsilon$ using $|B(\Gamma,2\epsilon)|\leq 4^d|B(\Gamma,\epsilon)|$. One could also obtain bounds when $\Gamma$ is dissociated by appealing to Rudin's inequality.

Coronavirus: Single parents at greater risk of job insecurity as half report poor mental health

Single parents are twice as likely to have poor mental health, compared with other family types, according to new research. Photo: Getty
Single parents in the UK are at greater risk of job insecurity as a result of the coronavirus pandemic, new research from Gingerbread and the Institute for Employment Studies (IES) has found.
As COVID-19 hit the UK in early 2020 single parents were less financially secure and on lower incomes than other family types, with mothers in coupled households earning almost twice as much per week as single mothers.
Nearly half (46%) of single parents worked in routine occupations compared to 26% of coupled parents. Routine occupations — also classed as semiand unskilled work — in retail, hotels and restaurants have been hit hard by the pandemic with lockdown closures causing many employers to cut hours and jobs.
Single parents are also twice as likely to have a zero hours contract as other family types which puts them at greater risk of job insecurity.
As many roles shifted to working from home during the first national lockdown, only 22% of single parents were able to move to remote working, compared to 35% of coupled parents, creating greater childcare challenges as schools and nurseries closed.
READ MORE: Parents hit hardest by lockdown energy costs in UK
Some 30% of single parents were furloughed under the government's Job Retention scheme (30%) compared to 21% of parents in a partnership, further reflecting single parents' caring responsibilities and highlighting that they are more likely to work in sectors affected by lockdown. It is more likely that these sectors will experience further job losses as businesses in England are hit by the second lockdown, due to last until 2 December.
Single parents were twice as likely to have poor mental health, compared with other family types, both immediately before and in the early stages of the pandemic. Overall 51% of single parents reported having depression, bad nerves or anxiety, compared with 27% of coupled parents.
Single parents reported experienced an 'impossible balancing act', as they struggled with making "constant trade-offs" between their work and caring responsibilities.

Worries about job security, the ability to secure new work, uncertainty around work requirements and formal and informal childcare availability, have made planning for the future impossible for single parents with many respondents feeling that "the unique challenges facing them had not been sufficiently accounted for in policy and guidelines developed."
Single parent charity Gingerbread is calling on the government to do more to support single parents during the coronavirus pandemic. The charity is urging the government to change policy to help single parents to stay in work by allowing them to access the furlough scheme where they need to do so for their caring responsibilities such as when a child needs to isolate.
Gingerbread is also calling on the government to make the Test and Trace Isolation Grant available to parents on low incomes who cannot work when their children are sent home from childcare or school to self-isolate.

Laura Dewar, policy and research at Gingerbread, said: "Single parents have been hit hard by the COVID-19 Crisis. Our research has shown that during the previous Lockdown single parents faced 'an impossible balancing act'. As the sole breadwinner and carer single parents having a job is vital for their family income and the financial security of their children.
"The government must to do more to support single parent families as we start the second lockdown. Single parents must be better supported to stay in work, find new work or re-train."

Views of stakeholders on career guidance services provided to pupils with hearing impairment at Nsonta secondary school in Kasama district of Zambia
MetadataShow full item record
The study investigated the views of stakeholders on career guidance services provided to pupils with hearing impairment at Nsonta Secondary school in Kasama district of Zambia. The study was guided by the following study objectives: to establish views of stakeholders on how career guidance was being provided to pupils with hearing impairment at Nsonta secondary school, to assess teachers' ability to communicate in sign language during career guidance activities at Nsonta secondary school; to explore views of stakeholders on content of career guidance provided to pupils with hearing impairment at the study school, and to document views of stakeholders on the relevance of career guidance services provided to pupils with hearing impairment at Nsonta Secondary School. The study was qualitative in nature and used a case study design. Interview guides were used on a sample of 25 pupils with hearing impairment two career guidance teachers and six subject teachers. The sample was selected using purposive sampling techniques while analysis of data was done thematically. The study revealed that: career guidance services were mostly provided through one to one approach, in groups and industrial education visits. It was also confident that career guidance teachers dealing with pupils, were knowledgeable of sign language. Hence, communicated effectively with pupils with hearing impairment regarding information on career guidance. Among the content of the information shared were: comprehensive sexuality, time management, choosing a career, knowing one's ability, studying techniques and choosing right friends. In terms of relevance, learners with hearing impairment had conflicting views. While the majority of the pupils considered the guidance service they received from the guidance teacher as relevant, however, the study expressed concerns such as failure among other pupils to comprehend some of the topics and limitations in use of sign language by some teachers. The study recommended that, teachers have adequate knowledge and skills in sign language through Continuing Professional Development (CPDs) programs to communicate well with pupils with hearing impairment and for them to benefit from the career guidance services being currently provided in the study school.

The Difference Between a Farmer and a Rancher
Close up on farmer hands
Crocodiles and alligators. Ghosts and spirits. Farmers and ranchers. Since this is an ag-related forum, let's talk about that last pair for a minute — is there really a difference? (Although maybe we'll dive into alligators and crocodiles later, who knows?)
When talking about one or the other, we usually try to say "farmer or rancher" to be as inclusive as possible. The definitions are a little ambiguous, so we want to cover all of our bases. By definition, a farmer is "a person who farms" and a rancher is "a person who owns or works on a ranch," but those are not the most descriptive explanations!
Because the words are a little subjective, we'll go over some of the most commonly accepted distinctions.
First, let's touch on a few similarities. People in both ranching and farming work long days outdoors and navigate the unpredictable weather. Grit, hard work and dedication are musts to be successful in either profession — and both are 24/7 ways of life.
However, there are some key differences.
Farmers usually focus on growing crops. They handle everything from planting seeds to harvesting. After harvest, they have to ensure proper storage to prevent rotting or contamination. Many farmers are also responsible for transporting their crops for sale.
Equipped with tractors, plows, combines and other machinery, farmers take great care to protect their land and get the best possible yield so they can help feed the world. Healthy soil plays a huge part in consistent crop production, so managing soil is top priority. Part of this effort is deciding whether or not to till their land. If you'd like to know more about the pros and cons of tilling, read up here!
Some farmers do work with animals, which can make the distinction confusing. Dairy and pig farmers fall under this category. For example, dairy farmers watch over and raise cows, with the ultimate goal of selling milk. And, also some ranching operations sell pork, we often use the term pig farmers for those who have their hogs penned and handle all care and feeding.
In general, farmers are to thank for fruits, vegetables and grains along with non-edible products like cotton and Christmas trees, with some yogurt, bacon and other items thrown in for good measure.
A specialized subset of the ag community is ranching. Traditionally, ranchers are known for grazing livestock on acreage for at least part of their lives. Ranchers raise, breed and care for animals of all kinds, which eventually gives us foods like beef, bison and more (yay, steak!).
Using stock trailers, feed troughs and squeeze chutes — a secure stall to keep animals still while receiving treatment or being examined — ranchers do everything they can to protect and look after their animals.
Keeping all the livestock healthy on a ranch is of the utmost priority. If diseases were to spread, it would be disastrous for the animals and for production. To keep things under control, ranchers make sure their animals get regular checkups and maintain good health.
Although farming and ranching are slightly different occupations, it's possible for a person to be both. Many folks farm the land for crops and raise livestock for meat.
Ultimately, we're darn thankful for both farmers and ranchers who put food on our tables and products in our homes.

|This popular port is a living museum and a window to America's seafaring past.|
Mystic's lifeblood has been the sea since its settlement in the 1600's. Some 600 vessels were built on its shores between 1784 and 1919, and most of its citizens were shipwrights who worked their farms in the summer and spent the rest of the year building the sloops and schooners that plied the rich New England waters as well as those of the southern states and the Caribbean.
Long an important fishing and whaling port, Mystic changed in 1838 when George Clark and Thomas Greenman set up their shipbuilding business on what would become the site of the Mystic Seaport Museum. Over the next 40 years, the Greenman yard launched almost 100 vessels, including sloops, clipper ships, and steamboats. The nearby Mallory shipyard, now the museum's restoration yard, also built clippers and steamboats.
American's inexorable tie to the sea is nowhere more evident than in Mystic. It's one of my favorite destinations while cruising in New England, and after you stop by, it will surely become one of yours.

Q.Over the past five years, I've built more than 30 laminate countertops, and I've never had any problems with them. Recently, however, one of my countertops started to bubble in a few places about five weeks after I built it. I tried taking an iron and heating the laminate, then flattening it with a J-roller until the laminate cooled. This worked, but for only about a week. What could be causing this to happen? And what can I do to fix this problem?
A.Merrill Glos, engineer at Formica Corp., responds: The most common cause of bubbling laminate is dimensional incompatibility between the laminate and the substrate. To prevent the problem, the substrate and the laminate must be compatible — they must respond to humidity changes by expanding and contracting at the same rates — and they must both be acclimated to the indoor environment before they are bonded.
If the laminate is dry and the particleboard is wet, the laminate will bubble when the laminate grows and the substrate either shrinks or stays the same size. It takes laminate about two days to acclimate, if air can get to both sides of the material. For a piece of 3/4-inch particleboard substrate, it takes about a week. The best substrate is particleboard, which has good dimensional compatibility with laminate. Plywood makes a poor substrate, because it is more dimensionally stable than laminate.
Solvent-based adhesives are preferable to water-based adhesives. When it comes to dimensional movement, wood reacts with moisture, not with solvent. Even with proper acclimation, if you use water-based contact adhesive, the water can disrupt the humidity balance by introducing water into the laminate or the substrate. Solvent-based adhesives tend to be more forgiving than water-based adhesives, and do not induce dimensional change problems.
To solve the problem, you'll have to heat up a larger area of the laminate than just the bubbled area. Heat up the bubbled area, as well as the entire area from the bubbles to the nearest laminate edge. This will allow the laminate to slip, adjusting to the change in dimension. After heating, use a 3-inch J-roller to rebond the contact adhesive, rolling until the adhesive is cool and has regained its strength.

You can use many expressions in the label expression dialog.
You might try using regex to get at some of the hard to reach problems.
Here is one of my old questions that can show how it can be used.
If it is just trailing or leading zeros you can use...
Right ([mycolumn],4)
that will drop everything in the front leaving only 4 characters from the right side.
Function FindLabel( [NAME] )
 Dim fldValue, aWords, i, word, aNewWords, NewWord, numElements, k
 fldValue = [NAME]
 'k = 0 'One word first line and two words all other lines
 k = 1 'Two words first line and all other lines
 if not IsNull(fldValue) then
 aWords = split(fldValue, " ")
 numElements = UBound(aWords)
 'Create new array to store new field value and redimmension to store
 'the correct number of elements to match original number of elements
 aNewWords = Array()
 Redim aNewWords(numElements)
 for i = LBound(aWords) to UBound(aWords)
 if i Mod 2 = k then
 word = aWords(i) & vbCr
 word = aWords(i)
 end if
 aNewWords(i) = word
 NewWord = Join(aNewWords, " ")
 NewWord = fldValue
 end if
 FindLabel = NewWord

Label expressions for a feature layer may be set by going to the the layers Properties>Labels tab, and click on the Expression button. However, Jakub has a good point that you should clean up your data first via field calculator. Here is the ArcGIS 10 link for feature expressions.
share|improve this answer
We are a large organization, and use SDE with strict permissions. I am not able to add a field unless I divorce the data from the SDE, and at that point, the end user would not benefit from modifications to the data (and indeed, we are about to update it), so that won't help here. – MLF May 12 '11 at 20:08
I'm not trying to modify labels on a feature layer. The custom overlay grid is a different beast all its own and does not have the same labeling options as the feature class itself. I want to inject some label class scripting into the actual grid. – MLF May 12 '11 at 20:11
What do you mean by "a different beast"? Isn't this a polygon feature class with attributes? it would be best to actually clean up the source data with vbscript or python, whichever you prefer. You can of course do it with label expressions but it has certain disadvantages such as slower drawing times... Kirk has provided a link to the manual. – Jakub May 13 '11 at 12:52
@ Jakub: This is a custom overlay grid. The only options to label a custom overlay grid are to label it according to one field inside the feature class, and there is no option to use a label expression. – MLF May 17 '11 at 16:31

When adding custom xFlow sensors, custom IPFIX, or custom Packet Sniffer sensors, you have the option to provide a Channel Definition using the following syntax (one entry per channel):
 - The must be 1 or a higher number, and it must be unique for the sensor. This means that each channel definition must have a unique ID.
 - The is linked to the historic data.
 i_round_redAs soon as you change the ID, you lose the history for this particular channel that the ID was linked to.
 - One rule can span multiple lines.
 - The is the channel's display name.
 - PRTG automatically adds one channel named Other. This channel counts all traffic for which you have not defined a specific channel.
The syntax is identical to the one described in the Filter Rules for xFlow, IPFIX, and Packet Sniffer Sensors section. Because data is accounted to the first match, make sure that you start with the most specific rule at the top and get less specific to the bottom.
i_round_redWe recommend that you write the rules list in an external editor first and then paste it into the Channel Definition field of the sensor in PRTG. If the rules contain an error, the entries are removed after adding them.
i_round_blueYou cannot delete channels of a sensor, even if you remove a channel from the channel definition. You also cannot change the display name of channels using the channel definition of custom xFlow sensors. Renaming is only possible via channel settings.

Robust Real-Time Optimization of a Solid Oxide Fuel Cell Stack
On-line control and optimization can improve the eﬃciency of fuel cell systems whilst simultaneously ensuring that the operation remains within a safe region. Also, fuel cells are subject to frequent variations in their power demand. This paper investigates the real-time optimization (RTO) of a solid oxide fuel cell (SOFC) stack. An optimization problem maximizing the efficiency subject to operating constraints is deﬁned. Due to inevitable model inaccuracies, the open-loop implementation of optimal inputs evaluated oﬀ-line may be suboptimal, or worse, infeasible. Infeasibility can be avoided by controlling the constrained quantities. However, the constraints that determine optimal operation might switch with varying power demand, thus requiring a change in the regulator structure.

- "Genshin Impact" has a few hidden mechanics that the game does not explain to players
 - The ICD system dictates the frequency in which elemental auras are applied by attacks
 - This system has a number of rules and exceptions for every character
The combat system in "Genshin Impact" is easy to understand and even easier to use in practice. However, there are plenty of things happening behind the scenes that the average player may not immediately notice. The ICD mechanic falls under this category.
Exploiting the ICD is important for maximizing damage output in "Genshin Impact." Much like the Elemental Gauge Theory, the game doesn't explain this mechanic at all, but members of the "Genshin Impact" community have put it upon themselves to try and discover how ICDs work by themselves.
What Are ICDs?
ICD, or Internal Cooldown, is a hidden mechanic that affects the frequency in which elemental attacks apply elemental auras on the same enemy. Simply put, elemental attacks can only apply elemental auras to enemies depending on their independent internal cooldown timers. Attacks cannot apply elemental auras in quick succession, except for some specific abilities.
There are two rules that determine when an aura can be applied:
 1. Attacks can only apply auras every 2.5 seconds.
 2. Attacks will reapply an aura after three hits.
These rules are independent of each other. For example, if Hu Tao inflicts a Pyro aura on an enemy, she will not be able to inflict another Pyro aura for the next 2.5 seconds or until she hits the same enemy four times in quick succession. If she fails to hit the enemy four times after 2.5 seconds, then her ICD will reset by virtue of the first rule.
Hu Tao, the 77th Director of the Wangsheng Funeral Parlor - Genshin Impact Hu Tao, the 77th Director of the Wangsheng Funeral Parlor Photo: Genshin Impact
Different attacks have unique ICD tags attached to them. These tags simply serve as indicators that let the game know what type of attack is being used.
Some attacks, such as Ganyu's charged shots, have no ICD timers and will always apply auras so long as they hit.
How To Exploit ICDs
Knowing a character's ICDs can help increase the efficiency of element application. This will help players make sure that no attacks go to waste when chaining elemental reactions.
For example, Diona's constellation passive that makes her aimed shots charge faster will not affect her aimed shot ICD, which means that every other hit on an enemy will not inflict Cryo.
Alternatively, each hit of Diluc's Elemental Skill will apply Pyro because each strike has a different ICD tag.
Working around ICDs is what makes quick-swap teams very viable. Players will be able to constantly apply and reapply an element so long as they use different attacks from different characters. This can result in big combos filled with elemental reactions if played properly.
Here's a detailed overview of ICDs provided by TenTen, one of the community's most helpful content creators for in-depth "Genshin Impact" information:


Enable or disable the properties of a command-queue.
cl_int clSetCommandQueueProperty( cl_command_queue command_queue,
 cl_command_queue_properties properties,
 cl_bool enable,
 cl_command_queue_properties *old_properties)
Specifies the command-queue being queried.
Specifies the new command-queue properties to be applied to command_queue. Only command-queue properties specified for clCreateCommandQueue can be set in properties; otherwise the value specified in properties is considered to be not valid.
Determines whether the values specified by properties are enabled (if enable is CL_TRUE) or disabled (if enable is CL_FALSE) for the command-queue. The allowed property values are the same as those specified for clCreateCommandQueue.
Returns the command-queue properties before they were changed by clSetCommandQueueProperty. If old_properties is NULL, it is ignored.
As specified for clCreateCommandQueue, the CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE command-queue property determines whether the commands in a command-queue are executed in-order or out-of-order. Changing this command-queue property will cause the OpenCL implementation to block until all previously queued commands in command_queue have completed. This can be an expensive operation and therefore changes to the CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property should be only done when absolutely necessary.
It is possible that a device(s) becomes unavailable after a context and command-queues that use this device(s) have been created and commands have been queued to command-queues. In this case the behavior of OpenCL API calls that use this context (and command-queues) are considered to be implementation-defined. The user callback function, if specified when the context is created, can be used to record appropriate information in the errinfo, private_info arguments passed to the callback function when the device becomes unavailable.
Returns CL_SUCCESS if the command-queue properties are successfully updated. Otherwise, it returns the following:
 - Returns CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue.
 - Returns CL_INVALID_VALUE if the values specified in properties are not valid.
 - Returns CL_INVALID_QUEUE_PROPERTIES if the values specified in properties are not supported by the device.

Footprint in Rock Art
footprint heavenly gates negev desert rock art
Footprint – Heavenly Gates in Negev Desert Rock Art, Israel
Many engraved footprints were found in Negev Desert rock art. Some researchers interpret them as symbols of god presence. Indeed, their similarity to a footprint confuses the visual interpretation, and our proof of their symbolic meaning is far from what envisioned. Detailed examination of these rock art reveals a repeating pattern that proves that they are symbols of heavenly gates.
According to the ancient concept, the gates of Heaven are Sumerian imaginary structures floating in the sky that serve as a gateway between heaven and earth. In Negev Desert rock art the gate resembles a footprint an idea copied directly from Sumerian cylinder seals. The gates are located at the ecliptic plane intersection with the horizon, the place where the Sun, moon, and planets rise and set. Another type of gate, the heavenly gate, leads to the world center or Paradise and it is located in the North Star vicinity situated above the Ursa Major constellation.
1. The Gate Astronomical Origins
John C Didier (2009) hypothesize that the imaginary heavenly gate is constructed from the stars around the North Pole. This includes the prominent stars and constellations around the North Star, such as Ursa Major, Ursa Minor, and Draco, which appear in many Sumerian cylinder seals, as shown in Fig2. The two Ursa Minor stars define the top and the two Ursa Major stars define the gate bottom. The imaginary lines connecting the four stars create a rectangle that forms the gate. This rectangular area surrounds Thuban, a star in the Draco constellation tail, the previous North Pole star and earth pivot about 5000 years ago, considered the location of Paradise. This gate mounted on the heavenly bull back, as illustrated in Fig.1, made from the outline of the Ursa Major constellation.

2. The Gates in Sumerian Cylinder Seals
Acadian cylinder seal Fig.2, dated 3000BC, depicts a gate, called the literature "The Bull and the Winged Gate". The winged gate supported by the heavenly bull, an Ursa Major constellation depiction, was imagined as a mechanism that allowed it to float in the air. Two gods on the gate sides are powering the gate by passing a rope between them, an action that implies movement, which depicts the winding Draco constellation. The gate wings look like sun rays of slightly different sizes also symbolizing the rise and set direction. On the right side in Fig.2, the larger wing symbolizes the rise direction and the smaller one, on left, symbolizes the set direction. The wings remind of birds' wings that award the gate the ability to float in the air. The similarity between the gates described by John C Didier, Fig.1, and the cylinder seal in Fig.2 is very clear.
The Epic of Gilgamesh 1500 BC contains the gate textual and pictorial testimony as described in Innana and the Celestial bull myth. On the right side of Fig.2, the cylinder seal describes a scene from this myth in which Innana steps out from the heavenly gate carried by the heavenly bull. She is heading straight from the gate, naked, and runs into the floating boat that sails the celestial ocean that separates heaven from earth. Note the adherence to the set/rise gate wings sizes in this cylinder seal.
3. The Footprint in Negev Desert Rock Art
Fig.4 presents Rock Art examples of footprints from the Negev Desert. They always appear as a pair comprised of rising and setting gates with wings. The gates resemble a footprint of slightly different sizes with the attached wings that look like ears. The gate schematic confirms the ideas in the Sumerian cylinder seals, which includes the adherence to the gates and wings sizes. The artist emphasized the differences in rising and setting direction by the gates sizes, the wings sizes, and the gate outlines thickness and fullness. The gates are in the shape of a footprint, which is the body part that walks through the gate.

Fig.5 illustrates a Rock Art example of four gates. The upper pair is the sun sunrise and sunset gates; the sun appears between them seen as a full circle. The lower pair is the moon rising and setting gates that appear between them. The gate size ratio, of the sun rising and setting, is maintained, however, the moon gates are of equal size since their brightness doesn't change.
Fig.6 shows examples of engraved rock art gates from the Negev Desert with their heavenly association. From left to right: 1. Venus entering the heavenly gate (see Venus Calendar) 2. Venus Star hovering above its gates. 3. The moon exits its rise gate (the right footprint), 4. An ibex enters the gate, half of it inside and half outside.

4. The Heavenly Gate celestial abstraction
Fig.7 shows two galloping horses carrying in tandem a rectangular structure. This unique arrangement represents the heavenly gate, which marked the entrance to heaven, and its ability to float in the sky. This beautiful and unusual scene actually depicts the constellations around the north star, see Fig.7, the most important sky region and the portal entry to heaven. The horses are a depiction of Ursa Major and Ursa Minor constellations. Don't look for the pictorial resemblance of the horses and constellations. It is all in the artist's mind that abstracted prominent constellation characteristics, around the north star, into familiar objects. The lower horse with its rectangle body and the kneeling posture reminds the shape of the Ursa Major constellation. The upper horse represents Ursa Minor constellation with its long tail depicting the Draco constellation that winds between these two constellations. The area where the Draco tail is crossing, the rectangular structure, marks the old North Star Thuban location, from 4th to 2nd-millennium BCE.

Fig.8 illustrates various gate engravings from the Negev Desert. The Sumerian cylinder seals and Negev Desert Rock Art similarity are compelling evidence for the Heavenly Gates abstraction. This includes details as gates sizes, wings sizes, and even a reminiscence of the Draco constellation seen as the wavy line within the gate.

Encyclopedia - Distinguished Service Cross (U.K.)
The British Distinguished Service Cross medal was awarded by military authorities to serving members of the Royal Navy for meritorious actions in the face of the enemy.
Instituted in 1901 as the Conspicuous Service Cross the medal was awarded to warrant and subordinate officers; it was renamed the Distinguished Service Cross (DSC) in October 1914 and made available to all Royal Naval personnel below the rank of Lieutenant Commander.
Some 1,983 DSCs were awarded during the course of the First World War. From 1916 a Bar was made available to denote formal recognition of further acts of merit to existing DSC holders.
The medal, which was made of silver, was 41mm in height and 35mm wide. The obverse of the medal showed the Royal Cypher on the circular central medallion surmounted by a crown; the reverse was plain other than for a hallmark with the year of the war engraved on the lower arm.
A "blimp" was a word applied to an observation balloon.

The Equipment tool offers you a simple and convenient way to insert non-structural, standalone elements such as pieces of furniture, hidro-sanitary equipments or electrical appliances to your projects. Equipments are based on Part shapes, which allow them to benefit from the solidity and possibilities of BRep geometry, and generate nice views when rendered to plan and section views.
As of version 0.17, equipment objects also have a DataHiRes property where a Mesh object can be attached. Equipment objects can then be made to display that mesh in the 3D view instead of their shape, which allows to use any high-resolution mesh objects such as detailed pieces of furniture commonly found on websites.
Furniture objects enclosed in an Arch Equipment object, with a high resolution mesh attached
When using the Arch OBJ exporter, all equipment objects that are in mesh display mode will be exported as their mesh instead of their shape.

Which is mathematically synonymous with:
(silence)(frog splash!) = old pond
old pond/frog splash! = silence
What we have done is to integrate the break of silence with the frog splash to define the old pond. Or the (the break of) silence is defined as the old pond divided by frog splash Furthermore we could also read it as the old pond divided by frog splash! Defines (the break of) silence.
I realize that I have added my own interpretation to El Konde's intention of 'silence' in his poem by redefining'silence' as 'the break of silence' but I think it is arguable that Basho was talking about the break in silence as opposed to silence itself. I believe my addition makes El Konde's version much more clear.
Now let's look at Bobs change to El Konde's Poem and its mathematical synonyms:
silence / frog splash! = old pond
silence / old pond = frog splash!
(frog splash!) (old pond) = silence
So what Bob expresses by his change is that the break of silence is defined by the integration of frog splash! and old pond or that the old pond is defined by the break of silence per frog splash and last but not least … frog splash is defined by the break of silence per old pond
Now that we have broke it down, you the reader can make your own decision on what version makes the most sense to you.
Note: (Bob's intention may have been to think of'silence' standing as itself, not as 'break in silence', but I doubt it especially since he has ignored it altogether in his new poem)
In conclusion lets look at Bob's Mathemaku for Basho:
(pond)(frog) = (((((((haiku)))))))
So it shows that Bob is consistent with multiplying pond and frog but he has 'defined haiku' as opposed to defining 'the break in silence'.
By putting parenthesis around the word haiku he has incorporated a vispo technique in his mathematical poem to imply splashing water waves.
So much for evolution,

Indian Navy SSB Interview Procedure
Many defense aspirants dream of being an Indian Navy officer or army officer or Air Force officer. There are several aspects that a candidate needs to focus while attending SSB Interview as one has to cross this barrier of selection to get recruited in defense services. So as to be selected in Indian defense services overall development of personality, knowledge and body is required. Candidate need to brush up his knowledge and bring him officer like qualities, in short one need to adapt an environment of defense services, discipline and attitude to get in SSB Interview. First step is to apply through exams like National defense academy (NDA) or combined defense service examination (CDSE) or Air Force Common Admission Test (AFCAT).
Second method is to apply various army, navy or air force courses and get admission through academic records after graduation through which a candidate needs to go for SSB Interview. SSB Interview is conducted as test in which there are different stages that candidate have to crack. It's a complete procedure of 5 days and they are mentioned as below:
The very first day of selection is the stage-1, where the candidate faces picture perception and description test and intelligence test for the analyzing of aptitude level of candidate. The tests that are carried out are as follows:
- Picture Perception and description test
- Intelligence Test
- Analyzing the Picture
- Candidates need to focus on the vital points like facts, characters, moods in the image, Gender and their age. Keen observation is required when pictures are shown to aspirants for writing a brief story.
The second day of selection is based upon the selections that had happened before in the previous round of selection i.e. stage-1. Those candidates need to focus on the next stages that they will face for test like:
- Thematic Apperception Test
- Word Association Test
- Situation Reaction Test
- Self-Description Test
These tests are conducted to know that how much attention does candidate pay while observing and their sense of judging things and situations.
This is the stage from where the complete procedure of performing in a group is carried on that is known as GTO Round-1. In this stage candidates need to face several tasks like:
- Group Discussion
- Group Planning Exercise
- Progressive Group task.
- Group Obstacle Race
- Half Group Task
This is the stage-4 that is carried out after candidate clears their third round of interview which was carried on day-3 and in this stage the tasks carried are:
- Individual Obstacles
- Command tasks
- Final Group Tasks
This round is last and final in which the candidates complete all the tough modes of task and last round in which conference is held where interview officer panel interview candidate i.e. personal interview is carried out on day-5 just normal round of questioning.
Once these all days are cleared candidate got hired as per his scoring in per round from day-1 to day-5.

Science Fair Project Encyclopedia
SPIHT (Set Partition in Hierarchical Trees) is an image compression algorithm that exploits the inherent similarities across subbands in a wavelet decomposition of an image. It implies uniform quantization and bit allocation applied after wavelet decomposition.
The algorithm codes the most important (in the sense of MSE reduction) wavelet transform coefficients in priority, and transmits the bits so that an increasingly refined copy of the original image is obtained with time.
The order in which coefficients are transmitted is recovered on the decoder using information of comparisons and sets being examined for significance during the sort, sets are created using hierarchical tree structure, i.e. Set Partition in Hierarchical Trees.
One of the advantages with SPIHT is that it produces an (optimal) embedded bitstream. This means that the bitstream can be truncated at any instant, and is then guaranteed to yield the best possible reconstruction.

How to: Perfect Mashed Potato
What's winter without a good mashed potato? Whether you like a smooth and creamy mash, or a chunky and rustic one, we want to make sure you're doing it right!
1. Choose the right potato
For fluffy mashed potatoes, stick with starchy potatoes like Agrias or the red-skinned Red Rascal. Avoid using waxy varieties as they don't contain a lot of starch, so don't break down well or absorb dairy as well as other varieties.
2. Start with cold water
We know it seems faster to start with hot water, but this can lead to uneven cooking. To ensure you cook them evenly, place the potatoes in a large pot and cover with cold water about 2cm above the potatoes.
3. Salt the water
Season your potatoes early by adding salt to the water when cooking. Potatoes absorb the water they're cooked in, so you won't need to add as much later, and more importantly your potatoes won't be bland!
4. Adding warm cream and butter
When you add cold dairy to the mash, the potatoes don't absorb the dairy well. So gently heat your cream (or milk) and butter, and then add.
5. Don't over-mash!
For anyone that's had gluey mashed potato, we feel for you! When potatoes are mashed starch is released. The more you work the potatoes, the more starch gets released, resulting in a thick, PVA glue like mash. Avoid over mashing, or using a food processor or blender.

During the process of acetylene production, the chemical reaction produces some amount of heat. The amount of heat dispelled during generation is monitored to ensure that it is not excessive. Heat is further reduced during the purification process and under normal operating conditions, should not become an issue.
However, during the process of regenerating purification material, heat is usually created in the purifier. If the temperature of the purifier increases disproportionately in isolated spots or places, this is known as hot spots which may result in damage to the purifier liner if not corrected. Understanding the causes and corrective actions of purifier hot spots will increase the safety of your operations as well as the life of your purifier.
Reasons for Hot Spot Formation in Acetylene Purifiers
Hot spots can be caused by:
- Insufficient air reaching the purification material
- Channeling of air through the purification material, rather than complete absorption into all of the material
- Partial blockage of the purifier vent
- Incomplete purge of the acetylene plant due to blockage of the purifier vent
Reverse Hot Spot Formation in Acetylene Purifiers
If hot spots are being formed in your purifier, it can be reversed by following the below-mentioned steps:
- Mechanical Disconnections
- Vent the Pressure
- Nitrogen Purging
- Reactivate the Purifier
Open the purifier vent valve in the following manner:
a. Open the vent
b. Close the purifier outlet valve
c. Close the valves at the bottom of the generator flashback arrestors
d. Open the purifier vent valve
a. Once the purifier vent valve has been opened, the pressure in the purifier should drop one lb. in five seconds and continue decreasing.
b. If the pressure drops in this manner, close the purifier and the inlet valve.
c. In case the pressure does not drop, the purifier vent might be blocked. This can be resolved by venting out the pressure from the flashback arrestor safety valves. Maintain the pressure at 6 psig or less.
a. Connect two nitrogen cylinders to the reactivation hose that passes through the purifier.
b. Force the nitrogen through the purifier. The nitrogen cylinder regulator should be set at 5 psi and 50 CFH flow.
c. At the same time, run water on the purifier vessel until the temperature of the cabinet is approximately 98 deg F.
(If more nitrogen is needed, additional cylinders should be connected and used until the temperature is reduced.)
d. Before reactivation, pressurize the purifier four times with nitrogen. After each time, it will be necessary to vent the pressure to remove all traces of acetylene from the purifier.
a. The purifier is now ready for reactivation. Disconnect the nitrogen flow and connect the airline.
b. Proceed to pass air through the cabinet at 50 CFH for eight hours.
c. The purifier should now be at room temperature. If it is not, then continue reactivation until the acetylene purifier reaches room temperature.
d. When the purifier nears room temperature, close the vent valve. Allow the pressure to build up to 5 psi and then vent the pressure.
e. Check for increase in temperature. If the temperature does not increase, pressurize to 10 psi and vent the pressure. Repeat two more times.
f. If the purifier has warmed up, continue reactivation until it reaches room temperature.
g. Remove the lid and check the purifying material for moisture content. If the material is dry, bypass all acetylene around the low pressure dryer.
h. If you are cooling the cooler condenser with well water, reduce the water flow such that the acetylene going into the purifier is a little warmer than the purifying material.
i. The purifier is now ready to be used.
After reactivation, check the purifier in fifteen-minute intervals to determine if there is occurrence of heat buildup during the cylinder charging process. This problem is most likely to occur during the first four (4) hours after reactivation.
The safety and efficiency of an acetylene plant is dependent on the functioning of the various components and parts of the plant. Hence, it is important that the plant is serviced in accordance with the procedures outlined in the operator's manual. Plant owners can also opt for a preventive maintenance plan that helps reduce failure rate of parts and ensures seamless functioning of the plant at all times. Customized preventive maintenance kits are available that include spares and other parts that can help implement a preventive maintenance plan.

Liko Vest for StandingShell is intended for raising patients who are practicing to stand with the aid of a standing shell.
A standing shell is much appreciated as an aid for disabled children and youths. However, applying the standing shell manually and raising the child in it can be very strenuous for the caregiver. But with the right lifting aids, these problems can be avoided.
We recommend the use of a lift and sling, for example SilhouetteSling, for lifting the child to the standing shell. For convenient access when it is time to lift the child out of the shell, SilhouetteSling is left inside the shell while the child is standing.
Vest for StandingShell is used during the actual raising operation and is placed outside the standing shell when the child is lying down, then connected to a patient lift. We recommend one of Liko's overhead lifts or the mobile lift Golvo. The raising is accomplished securely and controlled by patient lift.
Before lifting, keep the following points in mind:
- Choose a larger size of Vest for StandingShell than you would if you were using Liko MasterVest for the same patient.
- Leg Harnesses are included in the product to prevent the vest from sliding up along the standing shell.

Two positive numbers $\alpha$ and $\beta$ are given. We are going to describe a process of choosing a random vector on the unit sphere $S$ in $\mathbb R^3$ (given by $x^2+y^2+z^2=1$).
A vector $u\in S$ is chosen uniformly at random in the spherical disc with center $(0,0,1)$ and radius $\alpha$ on the sphere. After that a vector $v\in S$ is chosen uniformly at random on the spherical circle with center $u$ and radius $\beta$.
Can we describe the distribution of $v$ on the sphere (e.g., by specifying its density function or otherwise)? Clearly, $v$ lies in the spherical disc around $(0,0,1)$ of radius $\alpha+\beta$, however its distribution doesn't seem to be uniform. Can we estimate somehow the most frequent angle that $v$ subtends with $(0,0,1)$? The answer should certainly depend on $\alpha$ and $\beta$.
(By a "spherical disc" with center $c$ and radius $r$ we understand the set of points on the sphere whose distance from $c$ is at most $r$. Similarly, a "spherical circle" with center $c$ and radius $r$ is the set of points on the sphere whose distance from $c$ is exactly $r$.)
This question arouse related to the distribution of the polarization vector in a randomly grained polycrystalline material (ceramics).

I think you can get the answer as a one-dimensional integral using the spherical law of cosines. – Douglas Zare Sep 30 '12 at 20:44
Let $\theta$ be the angle the second radius $uv$ makes with the first radius $pv$ (where $p=(0,0,1)$) and let $\phi$ be the angle $v$ makes with $p$. Then the distribution of $v$ depends only on $\phi$, which in turn depends only on $\theta$, which is uniformly distributed. Calculate $\phi(\theta)$ and take $d\phi/d\theta$ and you have your answer. I get $\sqrt{1 - (\cot \alpha \cot \beta - \cos \phi \csc \alpha \csc \beta)^2} \csc \phi \sin \alpha \sin \beta$ in Mathematica, but I did not check this carefully. – Yoav Kallus Sep 30 '12 at 21:43

Banks, mortgage lenders, potential landlords and government agencies routinely verify income before making finance-based decisions. As an employer, either you or a representative from human resources or payroll writes the letter on an employee's behalf. However, if you're self-employed or are writing a letter to verify additional income, you'll need to write the letter yourself. Regardless, understanding the essentials can ensure the letter contains only relevant information.
A Letter Written on an Employee's Behalf
A proof of income letter written on an employee's behalf should be on company letterhead. Although it's not always necessary, a letter for a bank or mortgage lender may also require a company seal or a notary public stamp. The only information it should contain is the person's name, employment status -- full-time or part-time -- current job title, base annual salary and a statement as to whether the person is a permanent or temporary employee. The letter should end with the date, title and signature of the company representative issuing the letter.
Video of the Day
A Self-Written Letter
Except for a few modifications, a self-written proof of income letter has the same requirements as a letter written by an employer. As a self-employed person, use letterhead and include a statement as to how long you've been in business. A personal letter written to verify supplemental income should identify your income sources and attach any required verification documents such as tax returns, bank statements, or a Social Security, child support or worker's compensation award letter. Depending on the requestor's requirements, you may also need to specify how long you expect the income to continue and have the letter notarized.

The witching hour. Just saying it out loud can send shivers down your spine. Waking up in the middle of the night is the last thing you want (seriously, can you even remember the days of pulling all-nighters?), but at 3 a.m., this inconvenience can become downright spooky. If you've ever felt a hint of the paranormal in the middle of the night, you may have experienced the witching hour. Keep reading for a full understanding of the witching hour and what can happen during the dead of night — if you dare.
What Is the Witching Hour?
According to folklore, the witching hour is a specific time of night when paranormal activity is most likely to occur. That's because the veil between the living and the dead becomes thinner during this time. Ghosts and spirits can travel more easily between the two worlds, and the living become more aware of their presence here on Earth. If you wake up during the witching hour, you won't turn into Haley Joel Osment à la "The Sixth Sense" — but you may have a stronger sense of the supernatural.
When Is the Witching Hour?
The exact time of the witching hour depends on who you ask. Today, it's most commonly believed to occur from 3 a.m. to 4 a.m., in the darkest part of the night. This time has roots in religious beliefs, at least somewhat. Christians believe Jesus was crucified at 3 p.m. Since the devil is the inversion of Christ, 3 a.m. became known as the peak time of demonic activity. The number three can also be a mockery of the Holy Trinity, which may have led to the belief that 3 a.m. is the devil's hour.
Of course, the devil and witchcraft have nothing to do with one another. But people believed witches became more powerful at night, particularly at midnight. Others believed witches were active throughout the night, from sunset to sunrise. Over time, the 3 a.m. hour became known as the witching hour, probably because it coincided with other beliefs about supernatural activity.
What Happens During the Witching Hour?
Again, folklore is mixed about what happens during the witching hour. You've probably heard some of the superstitions, such as if you look in the mirror, you may see a ghost in the reflection. Those theories come from the belief that ghosts and spirits can pass more freely between the two worlds during the witching hour. That's also why mediums can communicate more easily with spirits during this time. For the same reason, paranormal investigators often conduct their research during the witching hour since there's a better chance to capture some supernatural activity.
Witching Hour Rituals
Let's be real: Unless you're a thrill-seeker, you probably don't want to wake up in the middle of the night with your heart pounding, scared to go to the bathroom in case you encounter a ghost on the way. But if you constantly wake up only to discover it's 3 a.m. again, here are some rituals you can do to calm down. Let the spirits do their thing, and you can sleep peacefully.
Create a Sleep Ritual
Technically, you do this before falling asleep, but it's still good advice. Create a sleep ritual to set yourself up for a good night's rest, minus the ghosts and demons. Turn down the thermostat or use a fan to cool your room to an ideal sleeping temperature. Set out some of your favorite crystals. Find ways to relax before bedtime, such as lighting a candle or diffusing essential oils. Do this same ritual nightly to prepare your body for sleep.
Wear a Sleep Mask
If you wake up during the witching hour, the problem may be light interfering with your sleep. Use a sleep mask to block the natural light from your windows or other sources. Of course, make sure you keep your bedroom dark. Hang blackout curtains or shades, so car headlights or an early sunrise don't wake you up.
Use a White Noise Machine
Block out the things that go bump in the night with a white noise machine. Sounds such as ocean waves and thunderstorms can help you fall asleep — and stay asleep. You can even download apps to play white noise from your phone.
Listen to a Podcast
The next time you find yourself awake during the witching hour, put on a podcast to calm your nerves and relax into a blissful sleep. Just search for "sleep podcasts," and you'll find tons of options. A podcast can give you something to focus on besides the ghost lurking in the corner. Kidding!
Is the Witching Hour Real?
So, here's the million-dollar question: Is the witching hour real? Like all things associated with the paranormal, it's difficult to prove, but it's certainly not impossible. The idea has become ingrained in modern-day culture, making it a popular reference in everything from horror movies to the scary stories you tell around a campfire. Some people swear they feel the presence of spirits in the middle of the night, while skeptics have doubts. And if you're a parent, the term "witching hour" may have a totally different meaning to you!
We can't tell you whether the witching hour is real or not. Honestly, that's something only you can determine for yourself. But you have to admit that there's a lot we don't know about the paranormal realm. So, the next time you wake up at 3 a.m., just know that the tingly feeling you have may not be a coincidence.

Hunger structure is a type of psychological hunger related to the environment, and it has a direct relation to people. It calls for people to be stable and be structured in their daily life. Thus on several instances children get used to the structures they were introduced to at a tender age. More so, it is closely related to what we do on daily basis, like how do we arrange our desks at our work place and how we spend our time during the day and night. It should be noted that each individual has his or her own structure and this is very crucial as it ensures our satisfaction. In situations like those of children, who are used to the usual routine, when they come home from the school, you must come up with a number of solutions that best suits them. For instance, one can use games among younger children, but in the cases, where they are mature you can introduce them to reading before they take a bath before going to bed.
Approximate hunger is concerned with the relationship with other people in terms of their number and the approximate distance from each other; however, this refers to the relationship of people to one another, which plays a vital role in acknowledgement of other people. Despite this, they are verbal in nature this can go hand in hand with the substitution of physical contact. This can be a gesture in receiving a public award though it is small in nature. This needs to be recognized by every individual person, but in other people it might come in large or huge numbers, however this works closely with the approximate distance between the individuals. The best example is wife and husband.
Housing or shelter refers to where one stays or lives or rather it is the residence of a given family. There are different types of shelter ranging from temporary to permanent in comparison to the hunger, housing or shelter have factors that influence both of them. In the case of structural hunger, where house equipments are arranged in a certain manner, for instance how the tables are arranged, the cupboards arrangements and the time management in the house. On the other hand, children are taught how to behave or rather conduct themselves, when they arrive from school. For instance, they should take a bath, read books and then go to bed. Similarly, hunger comes in close relation to the housing or shelter, which encompass on how people relate to each other and how they conduct themselves in a house. For instance, in cases, where greetings should be applied, that is a handshake, the nature of the house determines a lot. This depends on how small or big the house is. In cases where the house is huge, handshake is applicable, since people live in different rooms, but where the house is small handshake is not necessarily used, however in this case the main reward is just saying thank you to the reward that one is given in the house.
The book centers on several themes with inequality coming out clearly. In equality arises in the encounter in the lawyer who tries to fight out the cases of the poor and the homeless. Green is the person, who brings out the theme of segregation. It is also evident that Brock realizes that there are numerous unlawful and unjustified acts, which had been committed by his organization. He states that this was the main cause that made Hardy leave and became desperate. More so, despite poor squatters paying full amount as squatters, they are evicted by Branden. Therefore, class division is the main cause of inequality in the book. This is evidenced by Brock and Green in their acts of helping the poor and the less fortunate.

Tips for Using a Rubber Float With Grout
grout float on tile
 Tim Stocker Photography / Getty Images
Anyone who has successfully laid a tile floor or wall knows the satisfaction of a neat tile job. To take a stack of fired ceramic sheets and stick them in place with wet mortar is something approaching magic.
Once you master the skill of tiling, you'll want to tile every part of your house. And the crowning touch of all tile installations is the application of grout. Knowing how to use a rubber float with the grout means the difference between a clean tile job that lasts for years, even decades, and a tile job that cracks and eventually falls apart.
Why Use a Rubber Grout Float?
Grouting is an important part of any tile installation. Grout fills the spaces between tiles, called grout joints, to create a continuous surface.
At first glance, the most logical way to add grout would be to squirt it into the seams, as you already do when caulking other areas of your house. Not so. The way grout is applied is more of the shotgun approach rather than the laser-targeted approach. Large mounds of wet grout are scooped into the entire tire surface—seams and tile surfaces alike. Then, the grout is wiped across the tile. Grout embeds in the tile seams but not on the tile surface. Excess is picked up and redeposited elsewhere on the tile.
The only way to apply grout properly is by using a rubber grout float, which consists of a rectangular non-stick gum rubber or soft nylon pad that is firm but flexible and which prevents the absorption of materials.
The user holds the float with a C-shaped handle. The process of grouting with a float includes filling the joints with freshly mixed grout and scraping the tiles clean of excess grout. It is a simple yet elegant technique that has served tile setters for centuries and it's still used today.
Choose the Right Float: Wall or Floor
Rubber grout floats come in two types: wall floats and floor floats. The chief difference is that wall floats have softer rubber pads than floor floats, which can be quite stiff.
Wall floats are generally easier to use and are better for reaching into corners, so they are a better all-around choice for beginner tilers. The tools you find at the store may not indicate whether they should be used for walls or for floors. Some may be called a universal float.
Compare the softness of the pads to identify the type. Sometimes it is worth spending a little extra for a quality float, especially if you have a large tile job or if you plan to tile other rooms.
Move the Float Diagonally
As a general rule, almost always move the grout float diagonally over the grout joints. This prevents the edge of the float from sinking into the joints and pulling out the grout.
Sometimes you have to work parallel to joints, such as when grouting along the edge of a wall or floor, but do so with care. Otherwise, sweep the float diagonally.
Use a Lower Angle for Filling
Fill the grout joints by spreading the grout across the tiles while holding the float at an angle of about 45 degrees to the tile surface. This is the standard for floor tile. A higher angle might pull out too much grout from the seams, while a lower angle will smear the grout across the tiles.
When tiling walls, you may find a lower angle (about 30 degrees) more effective for filling the joints.
You can also reduce the angle if you reach a problem section that doesn't seem to be taking the grout very well.
Use a Steeper Angle for Cleaning
When all grout joints in a work area have been filled, make a second pass with the float to remove excess grout from the tile faces. This time, hold the float at a steep angle of about 80 to 85 degrees—almost straight up and down. When working carefully, a steep angle can clean the tiles without pulling grout from the joints.
Leave the Grout Haze For Later
A rubber grout float does a nice job of scraping the excess grout from the tile faces, but it cannot make the tiles perfectly clean. It usually leaves a film of chalky grout residue that you clean up with a grout sponge after the grout has set.
Your cleaning pass with the float should remove all blobs and chunks of grout, but you can leave the haze for later. Clean off the grout haze with a special solution called haze cleaner applied with a clean sponge.

Fixed tenon and single mortise: A tenon was shaped from the end on one timber and inserted into the mortise of the other. When the tenon of a large vertical timber was left unlocked, as in masts, and sternposts, it was said to be stepped.
Free tenon and two mortises: The most common method of edge-joining planking in ancient and early medieval vessels in the Mediterranean area, it also was used to secure adjoining surfaces of parallel timbers, such as stems and floor timber chocks. Corresponding mortises were cut into each planking edge; a single hardwood tenon was inserted into the lower plank and the adjacent plank fitted over the protruding tenon. In many instances, the joint was locked by driving tapered hardwood pegs into holes drilled near each strake or timber edge.
Free tenon and three or more mortises: Used in superstructure fabrications or places where hull planking was too narrow to provide sufficient seating for the desired tenon length. Al through small planking joints whose tenons are unpegged and contribute no structural strength are essentially coak joints, the term mortise-and-tenon joint has become universally accepted for all such forms of edge joinery.
