BHP, brake horse power, i mean... what is it? and how is it measured
psychology
it is the amount of power output by the engine.
Page: Difference Between HP and BHP (With Table) – Ask Any Difference

The brake horsepower is the amount of power output by the engine. It is represented by bhp. It is a theoretical approach for power measurement. It also includes frictional losses of the engine. The measurement of brake horsepower is carried out under controlled conditions in a laboratory. The measurement is done on either the crankshaft or the wheels of the system. A braking force is applied to balance the engine’s output force. Then, the output torque and rotational speed of the engine are measured. The brake horsepower is always higher than the horsepower.1bph is equal to 1.013869 hp.

Barcodes . Where are they stored , how do they work ?
psychology
Barcodes are stored on products. When a barcode is scanned, the product's details like price, quantity, and item code are scanned.
Page: Barcode FAQs: The Top 10 Facts About Barcodes, Answered

Barcodes on products are perfect for speeding up checkout. It eliminate manually keying in product details like price, quantity, and item code. Not only is this faster for the customer and cashier, but it also eliminates errors from manual entry. Retailers can also put barcodes on receipts. Many POS systems can create a barcode for a transaction that stores information related to the sale. Receipt barcodes can include the following information: * Date and time of purchase * Store number, if multiple locations * Register number * Associate or staff name * Item price * Coupons or discounts used * Method of payment If a cashier can scan a receipt and immediately access these details, it drastically speeds up the return or exchange process.

Car blinkers - timing seems arbitrary?
psychology
it's a design decision. the signal design elements are tailored to the specific facility conditions.
Page: traffic signal timing manual: chapter 4

the objective of signal design is to produce a design that yields safe and efficient operation for the prevailing conditions. this objective is accomplished by making design choices that are tailored to the specific facility conditions. signal timing settings (as described in chapter 5) can be changed as needed to accommodate changes in traffic demand, pattern, but signal design elements are relatively static and are typically more difficult (or costly) to change and thus are discussed as an introduction. the efficiency of an intersection is directly impacted by its signal design, and the detection layout can have a significant effect on the safety associated with high-speed intersection approaches (2).

Difference between pond, lake, and lagoon?
psychology
a lake is an area filled with water, localized in a basin, surrounded by land, and set apart from any river or other outlet that serves to feed or drain the lake. A lake is different from a pond because a lake is larger and deeper than a pond. A lake is different from a lagoon because a lake is surrounded by land and a lagoon is generally coastal part of the ocean.
Page: Lake

A lake is an area filled with water, localized in a basin, surrounded by land, and set apart from any river or other outlet that serves to feed or drain the lake.[1] Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions.[2] Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams.

Doctors don't deceive / falsify, then why when something is falsified it is referred to been Doctored?
psychology
Because doctors withhold, distort, obfuscate, fabricate, or lie about information that is crucial to the doctor-patient relationship.
Page: Lies in the Doctor-Patient Relationship

Clinicians realize that making an accurate diagnosis relies on the provision of reliable information by patients and their family members and that timely, astute, and compassionate care depends on effective bidirectional communications (between the patient and the physician). Unfortunately, both patients and physicians are often challenged by complicated communications; each group withholds, distorts, obfuscates, fabricates, or lies about information that is crucial to the doctor-patient relationship and to effective treatment. What doctors reveal, withhold, or distort matters greatly to their patients.1 Such untruths and manipulation of information can damage relationships and compromise clinical care.

psychology

In electronics and electrical engineering, it is by convention we define a point in a circuit as a reference point. This reference point is known as ground (or GND) and carries a voltage of 0V. Voltage measurements are relative measurements. That is, a voltage measurement must be compared to another point in the circuit. If it is not, the measurement is meaningless. The ground reference point is often, but not always—more on this later—represented by a standard ground symbol.

How are tunnels built under already existing infrastructure without causing damage to it?
psychology
They are built through the use of a pilot tunnel (or "drift tunnel").
Page: Tunnel

Conventional desk and preliminary site studies may yield insufficient information to assess such factors as the blocky nature of rocks, the exact location of fault zones, or the stand-up times of softer ground. This may be a particular concern in large-diameter tunnels. To give more information, a pilot tunnel (or "drift tunnel") may be driven ahead of the main excavation. This smaller tunnel is less likely to collapse catastrophically should unexpected conditions be met, and it can be incorporated into the final tunnel or used as a backup or emergency escape passage.

How are we able to accurately depict where galaxies ,light years away, are from us?
psychology
We are able to accurately depict where galaxies light years away are from us by looking at the present-time pattern of a beam of light.
Page: How does looking at distant galaxies allow us to look back in time?

Strictly speaking, when telescopes look at the light from distant galaxies, they are not literally looking back in time. The past no longer exists, so no one can directly look at it. Instead, the telescopes are looking at the present-time pattern of a beam of light. Since the beam of light has been traveling through the mostly-empty vacuum of space for millions of years, it has been largely undisturbed. Therefore, the present-time pattern of this beam of light is the same as the pattern that it had when it was first created by the distant galaxy millions of years ago. By looking at the present-time state of a beam of light, we can thus infer what the galaxy that created the light looked like millions of years ago.

Out of all these tips, the one to watch out for the most is the proper storage. The FDA revealed that when the disinfecting wipes are stored in extreme temperature areas that make them either too hot or too cold, the wipes can dry out, and the ingredients will undergo some changes. This implies that the ingredients responsible for preventing mold and bacteria growth on the disinfecting wipes will break down and be rendered useless. And since the growth of mold and bacteria is faster in warmer places, if your storage location is too hot, there is a great chance the wipes will grow mold.

How did rulers lead millions of people before there were any fast methods for communication?
psychology
by relying on oral testimony based on oaths taken in the name of God to tell the truth.
Page: Constitutional Rights Foundation

During the Middle Ages in Europe, most people lived in small, isolated villages. If people traveled at all, they typically ventured only a few miles from where they were born. For most people, the only source of both religious and worldly information was the village Catholic priest in the pulpit. News passed from one person to another, often in the form of rumor. Written documents were rare and often doubted by the common people as forgeries. What counted in important matters was oral testimony based on oaths taken in the name of God to tell the truth. Almost no one could read or write the language they spoke. Those few who were literate usually went on to master Latin, the universal language of scholarship, the law, and the Roman Catholic Church. Books, all hand-copied, were rare, expensive, and almost always in Latin. They were so valuable that universities chained them to reading tables.

How do the little touchpads work on smartphones when they only respond to human touch?

Page: Why Some Touchscreens Only Work With a Bare Finger

Capacitive touchscreens such as these rely on conductivity to detect touch commands. If you use a gloved finger or a stylus to control them, they won’t register or otherwise respond to your commands. Capacitive Touchscreens: What You Should Know Capacitive touchscreens live up to their namesake by measuring capacitance. In other words, they look for changes in a uniform electrical charge that’s applied to the top layer. When a capacitive touchscreen is turned on, an electrical charge will be applied to its top layer. Upon touching the top layer with a bare finger, your body will absorb some of the electrical charge. The capacitive touchscreen will then detect this change in capacitance as a touch command.

How does Egypt, a very Muslim nation, get away with assisting Israel so often?

The fall of Mubarak and the rise of the Muslim Brotherhood is equally troublesome for Palestinian officials in Ramallah, as it eliminates their most powerful Arab ally and emboldens their Hamas rivals in Gaza (Hamas being an off-shoot of the Brotherhood). The election of the Muslim Brotherhood’s Mohammed Morsi to be the first civilian president since the formation of the Egyptian republic sixty years ago has only intensified anxiety in Tel Aviv and Ramallah.

How does a flush toilet work?

It uses the force of water to flush human waste through a drainpipe to another location for treatment.
Page: Flush toilet

A flush toilet (also known as a flushing toilet, water closet (WC) – see also toilet names) is a toilet that disposes of human waste (principally urine and feces) by using the force of water to flush it through a drainpipe to another location for treatment, either nearby or at a communal facility, thus maintaining a separation between humans and their waste. Flush toilets can be designed for sitting (in which case they are also called "Western" toilets) or for squatting, in the case of squat toilets. Most modern sewage treatment systems are also designed to process specially designed toilet paper. The opposite of a flush toilet is a dry toilet, which uses no water for flushing.

How does grunting allow a person to tap into more of their strength?

A revelatory new study finds that yelling during sports could have greater benefits for performance than many of us might expect, even if it might cause spectators to look aghast and cover their ears. Grunting during physical activities that demand sudden short, sharp bursts of power, such as weight training, is common and probably has been used since our prehistoric ancestors hefted stones or heaved projectiles. Tennis players are particularly famous for grunting. Their shouts with each serve and stroke can be so loud that some players, including Martina Navratilova, have declared that the noise is a form of cheating, meant to confound the other player and not to increase the power of a stroke. But there has been limited past scientific scrutiny of the impacts of grunting. A 2014 study of college tennis players determined that grunting could indeed increase the power of players’ groundstrokes and serves.

The study, which was published in Environmental Science & Technology, found that the thermal decomposition of propylene glycol and glycerin, two solvents found in most “e-liquids” (the substance that is vaporized by the e-cigarette), leads to emissions of toxic chemicals such as acrolein and formaldehyde. “Advocates of e-cigarettes say emissions are much lower than from conventional cigarettes, so you’re better off using e-cigarettes,” said Berkeley Lab researcher and the study’s corresponding author Hugo Destaillats. “I would say, that may be true for certain users—for example, long time smokers that cannot quit—but the problem is, it doesn’t mean that they’re healthy. Regular cigarettes are super unhealthy. E-cigarettes are just unhealthy.” In the paper, “Emissions from electronic cigarettes: Key parameters affecting the release of harmful chemicals,” Destaillats and a team of researchers simulated vaping using three types of e-liquids in two different vaporizers operated at various battery power settings.

Is it true that microwave oven destroys a gigantic amount of food nutrients, proteins, vitamins and so on?

Microwave ovens usually don't destroy nutrients in food. In some cases, preparing food in a microwave might actually promote nutrient retention.
Page: Microwave cooking: Does it really strip nutrients and ruin our health?

Nutrients Although you may have heard that microwaves kill nutrition, that doesn’t seem to be true. Microwave ovens usually don’t destroy nutrients in food. And in some cases, preparing food in a microwave might actually promote nutrient retention. Nutrients are leached from food during any form of cooking, especially when the food is cooked for a long period of time with high amounts of water. So, for example, boiling carrots might strip nutrients much more drastically than microwaving them, because the carrots’ nutrients might get washed away with the boiling water. However, since we haven’t discovered all the compounds that make up food, we’ll likely never know all of the outcomes that microwaving has on nutrients.

Because they believe that they, not judges, juries, law enforcement or elected officials, should decide which laws to obey and which to ignore.
Page: Sovereign Citizens Movement

Sovereign citizens believe that they – not judges, juries, law enforcement or elected officials – should decide which laws to obey and which to ignore. Most sovereign citizens also don’t believe they should have to pay taxes. They clog up the courts with indecipherable filings and, when cornered, many of them lash out, retaliating through acts of paper terrorism and, in the most extreme cases, acts of deadly violence – usually directed against government officials. In May 2010, for example, a father-son team of sovereigns murdered two police officers with an assault rifle when they were pulled over on the interstate while traveling through West Memphis, Arkansas. The roots of the movement are racist and antisemitic.

The spleen is a fist-sized organ in the upper left side of your abdomen, next to your stomach and behind your left ribs. It's an important part of your immune system, but you can survive without it. This is because the liver can take over many of the spleen's functions.

String theory - why are there 11 dimensions?
psychology
There are 11 dimensions in string theory because it is 10-dimensional in superstring theory and 26-dimensional in bosonic string theory.
Page: String theory

String theories require extra dimensions of spacetime for their mathematical consistency. In bosonic string theory, spacetime is 26-dimensional, while in superstring theory it is 10-dimensional, and in M-theory it is 11-dimensional. In order to describe real physical phenomena using string theory, one must therefore imagine scenarios in which these extra dimensions would not be observed in experiments.

What are the differences besides prices between the grades of gasoline; Unleaded, premium and super unleaded?
psychology
They have different octane ratings. Unleaded has a typical octane rating of 95, while premium and super unleaded have octane ratings of 98 and 103, respectively.
Page: Unleaded and Super Unleaded Fuel Explained

Going to a petrol station, typically you can pick between ‘unleaded’, which is the standard petrol choice, or an alternative which will be called something like ‘premium unleaded’ or ‘super unleaded’. The latter can cost up to 10p more per litre than the standard unleaded petrol. Different fuel providers will have their own brand name for premium unleaded alternatives. But what is the difference between unleaded and these alternative, premium unleaded fuels? When is the best time to buy the latter? What is Super Unleaded? The main difference between regular unleaded petrol and premium-branded unleaded is that the latter will have an increased octane rating, also known as research octane number (RON). Creating petrol with a higher octane rating is a costlier process, hence the increased price. The benefits of using a fuel with a higher octane rating includes improved engine performance and lower consumption.

The Oath of Allegiance (Judicial or Official Oath) is a promise to be loyal to the British monarch, and his or her heirs and successors, sworn by certain public servants in the United Kingdom, and also by newly naturalised subjects in citizenship ceremonies. The current standard wording of the oath of allegiance is set out in the Promissory Oaths Act 1868. Variants of the basic oath of allegiance are also incorporated into a number of other oaths taken by certain individuals. Text[edit] The current standard oath of allegiance is set out from the Promissory Oaths Act 1868 in the following form: I, (Insert full name), do swear that I will be faithful and bear true allegiance to Her Majesty Queen Elizabeth II, her heirs and successors, according to law. So help me God. Under the Oaths Act 1888 (51 & 52 Vict. c.46), consolidated and repealed by the Oaths Act 1978, those who choose to may make a solemn affirmation instead of swearing an oath.

What is the difference between subprime mortgage bubble popping and the impending student loan debt crisis?
psychology
The student loan debt crisis is caused by risky lending, ballooning debt and market speculation, similar to the mortgage industry before the housing crisis.
Page: We should all be concerned about the student debt crisis

Many Americans are still recovering from the 2008 financial crisis. Almost everyone knows someone who lost a job, their retirement savings or even a home in its aftermath. While the effects of the Great Recession were felt throughout the economy, its main cause can be traced back to subprime lending in the mortgage industry. In the early to mid-2000s, lenders introduced risky products such as zero-down home loans and payment-option adjustable-rate mortgages, which enabled borrowers to take on more debt than they could afford. Lax lending practices led to increased demand and skyrocketing home prices. When the housing bubble burst and sent home prices plummeting, it set off a chain of defaults that snowballed into a recession. This cautionary tale of risky lending, ballooning debt and market speculation should be a clear warning of looming perils in the student loan industry.

Page: Bank run

A bank run or run on the bank occurs when many clients withdraw their money from a bank, because they believe the bank may cease to function in the near future. In other words, it is when, in a fractional-reserve banking system (where banks normally only keep a small proportion of their assets as cash), numerous customers withdraw cash from deposit accounts with a financial institution at the same time because they believe that the financial institution is, or might become, insolvent; they keep the cash or transfer it into other assets, such as government bonds, precious metals or gemstones. When they transfer funds to another institution, it may be characterized as a capital flight. As a bank run progresses, it generates its own momentum: as more people withdraw cash, the likelihood of default increases, triggering further withdrawals.

Where do the names for each day of the week originate from?

In many languages, the names given to the seven days of the week are derived from the names of the classical planets in Hellenistic astronomy, which were in turn named after contemporary deities, a system introduced by the Roman Empire during Late Antiquity[citation needed]. In some other languages, the days are named after corresponding deities of the regional culture, beginning either with Sunday or with Monday. The seven-day week was adopted in early Christianity from the Hebrew calendar, and gradually replaced the Roman nundinal cycle as the new religion spread.[citation needed] Sunday remained the first day of the week, being considered the Lord's Day, while the Jewish sabbath remained the seventh. Emperor Constantine adopted the seven-day week for official use in CE 321, making the Day of the Sun (dies Solis) a legal holiday.

Lying in bed unable to fall asleep is often called conditioned or learned arousal, says sleep-medicine specialist Philip Gehrman, an assistant professor of psychiatry at the University of Pennsylvania. It’s one of the most common sleep problems, and experts think it happens because something in your sleep environment has told your brain that getting in bed should “arouse” you or wake you up, instead of put you to sleep. “If someone is a good sleeper, then each night they probably get in bed and fall asleep. So when they get into bed it triggers this auto response of sleepiness,” Gehrman says.

A correspondent asks whether there is any demand for Latin among secondary students (Letters, 8 August). Indeed there is. Over the past 10 years, the charity I co-founded, Classics for All, has supported the reintroduction of Latin, Greek and classical civilisation to 1,000 state primary and secondary schools. At primary school, pupils have loved learning Latin, coming to it with no preconceptions about elitism or difficulty. They move on to secondary school expecting Latin to continue. The first cohort of students is now studying classics at university. Demand built, and it is being met. Far from being a dead language, Latin today is a living subject that broadens cultural understanding and educational horizons, and, perhaps most importantly, is truly enjoyed by thousands of pupils across the UK.

Pretax profits at the division soared 35% to nearly £102m as revenues rose by 29% to nearly £3bn, according to accounts about to be published by Companies House.

Why do men immediately get soft after ejaculation?
psychology
Because of the release of the brain chemical prolactin, which is associated with feelings of sexual satisfaction and sleepiness, men are temporarily less interested in sex after ejaculation.
Page: ‘My boyfriend loses interest in sex after he orgasms’

Research shows that during ejaculation, men release a cocktail of brain chemicals, including norepinephrine, serotonin, oxytocin, vasopressin, nitric oxide, and the hormone prolactin. Prolactin represses dopamine, a key chemical in desire and motivation, and is linked both with sleepiness and feelings of sexual satisfaction. It’s thus a de-arouser of sorts, and temporarily decreases men’s desire for sex. Studies have shown that men deficient in prolactin have faster recovery times. Interestingly, studies have also shown that orgasms enjoyed through partnered sex release four times more prolactin than orgasms from masturbation, which means that men are less likely to feel sleepy and calm after masturbating.

There are a number of possible explanations. One is that the "-er" suffix is a marker of the agent or the doer of the action. Since mothers and fathers are the ones who do the parenting, and since daughters are the ones who are parented, the "-er" suffix is appropriate. Sons, on the other hand, are not the ones who do the parenting, nor are they the ones who are parented, so the "-er" suffix is not appropriate.

My daughter-in-law’s parents live three hours away. Even though he lives close by, my son hardly calls or comes over. He tells us he’s busy working and being a father and husband. We do hear from him when he needs something, like someone to watch the grandkids.

Why do people sometimes end up driving on the wrong way of the road?
psychology
It is due to driver inattention or impairment, or because of insufficient or confusing road markings or signage.
Page: Wrong-way driving

Wrong-way driving (WWD), also known as counterflow driving, is the act of driving a motor vehicle against the direction of traffic. It can occur on either one- or two-way roads, as well as in parking lots and parking garages, and may be due to driver inattention or impairment, or because of insufficient or confusing road markings or signage,[1] or a driver from a right-hand traffic country being unaccustomed to driving in a left-hand traffic country (see Left- and right-hand traffic), and vice versa.

Why do strawberries have their seeds on the outside?
psychology
Because strawberries are the only fruit that wear their seeds on the outside.
Page: Strawberries 101

Strawberry Fact 1. Strawberries are the only fruit that wear their seeds on the outside. The average berry is adorned with some 200 of them. No wonder it only takes one bite to get seeds stuck in your teeth. Strawberry Fact 2. Strawberries aren’t true berries, like blueberries or even grapes. Technically, a berry has its seeds on the inside. And, to be über technical, each seed on a strawberry is considered by botanists to be its own separate fruit. Whoa, meta! Strawberry Fact 3. Strawberries are members of the rose family. Should you come upon a bush of them growing, you’ll see: they smells sweet as they taste.

Why does your abdomen tickle when you drive over a hill?
psychology
It's the reduction in blood flow through the gut in turn produces the oddly characteristic "butterflies" feeling in the pit of your stomach.
Page: What Causes a 'Butterflies in the Stomach' Sensation?

While adrenaline contracts most of the gut wall to slow digestion, it relaxes a specific gut muscle called the “external anal sphincter”, which is why some people report a pressing need to visit a bathroom when they’re nervous. This reduction in blood flow through the gut in turn produces the oddly characteristic “butterflies” feeling in the pit of your stomach. It senses this shortage of blood, and oxygen, so the stomach’s own sensory nerves are letting us know it’s not happy with the situation.

Anti-vaccine advocates have swayed parents in New York to refuse immunizations for their kids, sparking two of the largest measles outbreaks in the state’s recent history, according to local health officials. As of April 10, at least 285 people in New York City — mainly in Brooklyn’s Williamsburg and Borough Park neighborhoods — had fallen ill. In nearby Rockland County, 168 people have caught the virus. The outbreaks have prompted health officials in both areas to declare states of emergency. In the city, officials ordered mandatory immunizations among unvaccinated people on Tuesday, threatening those who opt out with fines. Nearby Rockland took the unusual step of barring anyone under the age of 18 who hadn’t been vaccinated for measles from public places for 30 days in March.

Why is it that I can use the same chocolate chip recipe but come out with varying results each time?

Why is it that sometimes original potato chips have a green shade to the chip?
psychology
Because of the presence of a glycoalkoid named solanine.
Page: Why are some potato chips green? Are they poisonous?

The potato is such a universal food that it can be found in almost all cuisines. It is a part of daily staple in many regions. The westerners have a particular liking for the potato chips, known in various names like French fries, crisps etc. The vegetable is usually round and brown. However, very rarely, you may come across a green spud; either in those you brought from the market or in that packet of chips you bought for the midday snack. Some people don’t really mind but others immediately frown and subject it to intense scrutiny before deciding to eat it or throw it out. Many think that the greenish tint is poisonous, and there a fair bit of truth in it. The greenish tint on the spud is actually chlorophyll, the pigment that gives green color to all the plants in the world. While chlorophyll itself is not harmful, it is the presence of a glycoalkoid named solanine that poses danger to us.

Why is it that when it's windy outside, the water in toilet bowels move, even in appartment buildings?

Because of the sanitary vent acting like a "road draft tube" and applying a bit of a suction effect on the water pulling some over the lip of the p-trap.

A: Most likely due to the sanitary vent acting like a “road draft tube” and applying a bit of a suction effect on the water pulling some over the lip of the p-trap. Wind pulses the pressure seen by the toilet through its vent stack, causing water level in the bowl to rise and fall. At every rise, it overflows the trap. You probably have no function in your toilet tank to replenish what overflows, and the level goes down.

Why is liquid almost always stored in round containers on trucks?
psychology
Because a cylindrical container doesn't have 'weak spots' that need reinforcing, which would translate to using more material to build the tanker.
Page: Why Do Liquid-Carrying Tanker Trucks Have Cylindrical Tankers?

Firstly, a cylindrical container doesn’t have ‘weak spots’ that need reinforcing, which would translate to using more material to build the tanker. In contrast, a rectangle/square has corners and flat sides, which create weak points for pressure. In other words, a rectangle-shaped container would fail faster than a cylindrical one upon experiencing a great deal of pressure. That’s the same reason why windows in commercial airplanes have rounded corners, rather than being perfectly rectangular/square-shaped.

Why is meat from pigs lighter in color than most other mammals?
psychology
Because of the difference in fiber types, the pig's muscles have less myoglobin, and so the meat is lighter in color.
Page: Science of Meat: What Gives Meat its Color?

White meat is made up of muscles with fibers that are called fast-twitch. Fast-twitch muscles are used for quick bursts of activity, such as fleeing from danger. These muscles get energy from glycogen, which is also stored in the muscles. White meat has a translucent "glassy" quality when it is raw. When it's cooked, the proteins denature and recombine, or coagulate, and the meat becomes opaque and whitish. Cows and pigs are both sources of dark meat, though pig is often called "the other white meat." Pigs' muscles do contain myoglobin, but the concentration is not as heavy as it is in beef.

Alkaline manganese dioxide batteries, commonly known as alkaline batteries, are good all-around batteries for everyday electronic devices and last longer than some other types. However, lithium iron disulfide batteries, or lithium batteries, have several distinct advantages over their alkaline counterparts: - They're designed to last longer, making them a good choice for high-tech and smart devices, and those electronics for which changing the battery is inconvenient. - They can withstand extreme low temperatures. Lithium can operate without failing in a very cold climate, so it's ideal for outdoor applications. - Lithium batteries are lighter than alkaline batteries, so they offer an advantage when used with portable devices, especially cordless power tools.
