In USA AM broadcasting, presunrise authorization (PSRA) and postsunset authorization (PSSA) are permission from the Federal Communications Commission to broadcast in AM on mediumwave using a power level higher than what would normally be permitted prior to sunrise/after sunset, or in the latter case, provide Class D stations with service into the evening where they would otherwise be required to sign off. Sunrise and sunset times are provided on the licensee's basic instrument of authorization.The power level for both PSRA and PSSA service cannot exceed 500 watts. Power calculations are based on co-channel stations.

In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used.To build a key from shared secret, the key derivation function is typically used. Such systems almost always use symmetric key cryptographic algorithms.

Pre-green is a golf term used to describe the grass between the green and the fairway. Around a foot in width, the grass is slightly shorter than that of the fairway, but longer than the green itself. The pre-green is commonly mistaken for the fringe. The fringe is the change in level from the green to the pre-green. Many courses don't make use of the pre-green, which means the fringe will connect the fairway and the green directly.The pre-green carries the same rules as the fairway, not the green. Golfers cannot mark or pickup their ball, but the flag may remain in the hole for their shot without incurring a penalty.In some cases, as with The Little 'B' Open in Spain, a player might be closer to the pin on the pre-green than a player actually on the green. The next shot honor will go to the pre-green player, as they are officially not on the green.

A prelit tree is a convergent product of Christmas lights and an artificial Christmas tree. The product is an artificial fir tree that comes pre-wired and strung with lights, which cannot be removed and are usually embedded within the artificial branches. The product can be sold as a kit - the user assembles the tree and plugs it into an electrical outlet - or the dealer may assemble it before the sale. Prelit trees may have traditional mini bulb lights, LED lights, or fiber-optic lights. Larger trees usually contain traditional strands of bulb lights while smaller tabletop trees have fiber optic branches. Some more expensive trees come with energy-efficient LED lights. Prelit trees are being classified into the categories of electrical products.

The Pre-salt layer is a geological formation on the continental shelves. It is the geological layers that were laid down before a salt layer accumulated above them during the Gondwana breakup. Some of the petroleum that was formed in the pre-salt layer has not leaked upward (see salt dome) to the post-salt layers above. This is especially common off the coast of Africa and Brazil. The amount of oil is not well known but is thought to be a significant fraction of world oil reserves.

A pre-school playgroup, or in everyday usage just a playgroup, is an organised group providing care and socialisation for children under five. The term is widely used in the United Kingdom. Playgroups are less formal than the pre-school education of nursery schools. They do not provide full-time care, operating for only a few hours a day during school term time, often in the mornings only. They are staffed by nursery nurses or volunteers, not by nursery teachers, and are run by private individuals or charities, rather than by the state or companies.In the United Kingdom, since around the 1980s, the traditional territory of the playgroup has been encroached on by the expansion of more formal nursery education, and playgroups often now cater only for two- and three-year-olds before they move onto a nursery school. Over the same period there has been an increase in the state supervision of playgroups.

In cinematography and photography, pre-flashing is the exposure of the film or other photosensor to uniform light prior to exposing it to the scene to be imaged. This adds a bias to the overall light input recorded by the sensor.It is sometimes used for artistic effects, as it can be used to add a colour cast to shadows without significantly affecting highlights.It is also used in fields such as astronomy to bias CCD image sensors into a linear region, improving their low-light sensitivity.

Pre-Pharmacy or Pre-Pharm is the term used for a 2-year undergraduate course that Pharmacy students must first complete before moving onward to a 4-year Pharm.D program within the United States.The program is offered in a few different ways across the country. Within some colleges, the Pre-Pharmacy coursework is combined with the Pharm.D course for a 6-year program. Colleges that do not offer this merged program may allow an undergraduate student to major (or minor) in Pre-Pharmacy.

Pre-medical (often referred to as pre-med) is an educational track that undergraduate students in the United States and Canada pursue prior to becoming medical students. It involves activities that prepare a student for medical school, such as pre-med coursework, volunteer activities, clinical experience, research, and the application process. Some pre-med programs providing broad preparation are referred to as “pre-professional” and may simultaneously prepare students for entry into a variety of first professional degree or graduate school programs that require similar prerequisites (such as medical, veterinary, or pharmacy schools).

In the United Kingdom, Her Majesty's Revenue and Customs acted against certain inheritance tax (IHT) avoidance schemes by imposing a standalone income tax charge. The tax was introduced in the Finance Act 2004 and came into effect from 6 April 2005.This has become known as pre-owned assets tax (POAT). POAT applies where an individual disposes of an asset but somehow retains the ability to use or enjoy it.

Pre-Health Sciences refers to the undergraduate courses to prepare American college students for admission in medical, dentistry, pharmacy, optometry, veterinary, and physical therapy schools, and for training as a physician assistant. In the United States, colleges have moved away from the impractical designation of students as "Pre-med" majors, as only a small percentage of applicants actually achieve admission into medical schools. As such, students are given the choice to focus on the coursework required for admission.

The Europeans made ships with metal ribs as rams, and there are also documents about armoured ships, some of them equipped with naval artillery. In East Asia there are records about metal armoured warships combined with naval artillery from the 16th century. However, in every single case of both European and Far Eastern vessels evidence of iron armour is either unclear, ambiguous or disputed.

Pre-movement time is the time before, and the concomitant events and situational analyses prior to, an evacuation of an area. The term is generally used in referring to large-scale evacuations where the necessity thereof is foreseen. Events that can require pre-movement time include hurricanes, wars, nuclear accidents, and major conflagrations.Pre-movement time is divided into four distinct events: detection, the recognition of the emergency; decision, to commence evacuation or not, and of how many people and how great a territory; alarm, the announcement of the decision and conveyance to the populace, often by emergency broadcasts or over police loudspeakers, or by actual alarms, such as sirens; and reaction, the events and actions of the people affected, both emergency personnel and the citizenry, immediately after the declaration.Panic is rarely observed during this time, despite media depictions to the contrary. At first, lack of response arising from ignorance of the situation to outright disbelief or denial, is often noted. Different, confusing stimuli (e.g., smells of burning or smoldering, smoke, power outages, or tremors )may be detected and not put together to form a plan to evacuate, thus increasing pre-movement time. If occupants are performing some task or engaging in an activity, they may complete their business before tending to the crisis, even if they had some prior knowledge of it.As stimuli increase, those affected likely will attempt to ascertain the cause(s); some may walk around their immediate area, look in rooms or offices, and open doors. They may call the custodian or building superintendent to find out the problem. If no response is forthcoming, those affected likely will begin to talk among themselves and figure out the best plan of action. Depending on the information and cues available, this pre-movement time can last from a few seconds to several minutes.Part of pre-movement time also involves actions related to saving a structure (especially one's own home or domicile) or personal valuables. Some people will warn others of a danger, especially those close to them like family or dear friends. Evacuees will often contact family members by phone or e-mail to let them know that they are safe and are starting their evacuation. These types of actions are all part of pre-movement time.Reaction time to an evacuation can vary widely, depending on the type of emergency, its perceived danger, and any false alarms of such an emergency beforehand. It can even be affected by the means of communication. In one study, mock alarms were broadcast to subway riders in London, England using different forms of address: a simple bell, a bell followed by instructions from subway staff, a public address announcement lasting 30 seconds and broadcast twice, a combination of staff instructions and public address, and finally by instructions, public address, informing people of the emergency, and announcing the type of emergency. In most cases, but not always, the more forceful the call to evacuate and the more staff were involved, the quicker riders got on escalators to evacuate.

Pre Settlement Funding (pre-settlement loan or lawsuit loan) is used to define the type of funding intended to provide funds to the plaintiff in a lawsuit, before the case is finally resolved by a court decision or settlement. This funding helps plaintiffs who have immediate needs, such as medical care, secure financial help before the legal proceeding has run its course, often a matter of several years.

Colleges that do not offer this merged program may allow an undergraduate student to major (or minor) in Pre-Pharmacy. For schools where Pre-Pharmacy is not offered as a major or minor by itself, students usually major in a similar science (i.e. Chemistry) with a focus on Pre-Pharmacy, meaning that the curriculum of their particular major is tailored to help them take the PCAT and get into a pharmacy school.Each college has its own specific curriculum for Pre-Pharmacy students. A general curriculum would include Chemistry, either Biology or Anatomy and Physiology, Mathematics, English and various electives, which may include Physics or Anthropology. Specific curricula can generally be found on the individual college's website.

Pre-installed software (also known as bundled software) is software already installed and licensed on a computer or smartphone bought from an original equipment manufacturer (OEM). The operating system is usually pre-installed, but because it is a general requirement, this term is used for additional software apart from the bare necessary amount, usually from other sources (or the operating system vendor).Unwanted pre-installed software (also known as crapware or bloatware) can include major security vulnerabilities, like Superfish, which installs a root certificate to inject advertising into encrypted Google search pages, but leaves computers vulnerable to serious cyberattacks that breach the security used in banking and finance websites.Some free download websites use unwanted software bundling that similarly installs unwanted software.

In the music industry, a pre-release cover version is a type of cover version that arises when a cover artist releases a version of a song before the original artist does. This practise takes advantage of a 'release window'; it occurs when an upcoming song has lots of airplay but has not yet been released. Pre-release cover versions are common in the UK because of the unique situation there in that songs by big acts get weeks of airplay before being released, giving cover artists enough time for session musicians and computer experts to record a near-exact cover version of the song. For example, UK #1, "Talk Dirty" by Jason Derulo ft. 2 Chainz, made #71 the week before it made #1 in the form of a pre-release cover version by Select Hits. Usually the original artist's record label will notice the cover version and release the original early; when Can You Blow My covered Flo Rida's "Whistle", Rida's record label rush-released the song mid-week. Avicii's "Wake Me Up!" was intended to be released on 8 September 2013 however on 15 July 2013 the Official Charts Company announced that it would be released that week after a group called 'Spark Productions' recorded a pre-release cover version and made #26 on the UK Singles Chart with it.A successful pre-release cover version is Precision Tunes' version of Maroon 5's "Payphone", which sold 34,492 copies and charted in the top ten on three charts. After the Sunday Telegraph tracked him down, he said that "We have currently restructured [PT Records] and its employees, [and] are in the process of issuing takedowns [of our previously released covers] and researching accounting for those releases and plan to relinquish any monies made on the nine releases".

In chemical kinetics, the pre-exponential factor or A factor is the pre-exponential constant in the Arrhenius equation, an empirical relationship between temperature and rate coefficient. It is usually designated by A when determined from experiment, while Z is usually left for collision frequency.For a first-order reaction, it has units of s−1. For that reason, it is often called frequency factor.The frequency factor, A, depends on how often molecules collide when all concentrations are 1 mol/L and on whether the molecules are properly oriented when they collide.Values of A for some reactions can be found in here.

In the context of healthcare in the United States, a pre-existing condition is a medical condition that started before a person's health insurance went into effect. Before 2014 some insurance policies would not cover expenses due to pre-existing conditions. These exclusions by the insurance industry were meant to cope with adverse selection by potential customers. Such exclusions are prohibited after January 1, 2014, by the Patient Protection and Affordable Care Act.

Pre-primary education in Mauritius is the stage of education to be completed prior to the start of primary school, which is compulsory for all students of ages 3 to 5 in Mauritius. The pre-primary programme of study lasts for three years, termed as Year 1, Year 2, and Year 3. Upon completion of the pre-primary years of study, students may enter into primary school, which continues to the award of the Certificate of Primary Education for students who successfully complete primary school studies with passing marks on the final exams.

The pre-integration complex (PIC) is a nucleoprotein complex of viral genetic material and associated viral and host proteins which is capable of inserting a viral genome into a host genome. The PIC forms after uncoating of a viral particle after entry into the host cell. In the case of the human immunodeficiency virus (HIV), the PIC forms after the Reverse Transcription Complex (RTC) has reverse transcribed the viral RNA code into DNA code.

A pre-replication complex (pre-RC) is a protein complex that forms at the origin of replication during the initiation step of DNA replication. Formation of the pre-RC is required for DNA replication to occur. Complete and faithful replication of the genome ensures that each daughter cell will carry the same genetic information as the parent cell. Accordingly, formation of the pre-RC is a very important part of the cell cycle.

A pre-game show or pregame show is a television or radio presentation that occurs immediately before the live broadcast of a major sporting event. Contents may include:replayed highlights of each team's previous games.analysis of the strengths and weaknesses of each team by sports commentators.interviews with fans and coaches from each team.shots of crowds filing into the arena or stadium.The networks that broadcast the NFL were the first networks to create and air pre-game shows. CBS was the first to broadcast a sports pre-game show in 1964, when the network launched a 15-minute regional sports program that interviewed players and coaches and featured news and features about the league. The show aired immediately before games on CBS. The show originated in studio and live from the fields, and featured broadcaster Jack Buck. In 1967, the show grew to 30 minutes in length and in 1976, aired a new 90-minute “Super Bowl Special” before Super Bowl X. The show moved to two hours long in 1984 and featured 11 broadcasters, 13 producers and four directors.FOX created its own pre-game show when it won the rights to broadcast NFC games in 1994. The network hired James Brown to host the show and brought on analysts such as Terry Bradshaw to lead the coverage. In 2006, Brown left the network to return to CBS and host their pre-game show, NFL Today.NBC launched its own version of a pre-game show – Grandstand – in 1975, and not only featured NFL programming, but other sporting events around the nation. The show led up to the NFL's 1 p.m. games but covered college football, golf, tennis and many other sports and topics. The network hired Jack Buck to host the show and the show didn’t just preview that day’s NFL games but did investigative pieces on a variety of topics.Starting from Wrestlemania 28 WWE have aired a monthly live half an hour pre-show on YouTube before each of their PPVs featuring a match, an interview and the hype for the subsequent PPV.Pre-game shows generally run for 30 minutes to one hour, though for some big events such as the Super Bowl, a pre-game show has run up to six hours in length. While most pre-game shows are done in a studio (sometimes with live shots to someone at the event itself), some shows travel to certain locations to broadcast – the most famous being ESPN’s College Gameday pre-game show, which broadcasts live from various college campuses for football and basketball games.

A pre-money valuation is a term widely used in private equity or venture capital industries, referring to the valuation of a company or asset prior to an investment or financing. If an investment adds cash to a company, the company will have different valuations before and after the investment. The pre-money valuation refers to the company's valuation before the investment.External investors, such as venture capitalists and angel investors will use a pre-money valuation to determine how much equity to ask for in return for their cash injection to an entrepreneur and his or her startup company. This is calculated on a fully diluted basis.Usually, a company receives many rounds of financing (conventionally named Round A, Round B, Round C, etc.) rather than a big lump sum in order to decrease the risk for investors and to motivate entrepreneurs. Pre- and post-money valuation concepts apply to each round.

The Pre-salt layer is a geological formation on the continental shelves. It is the geological layers that were laid down before a salt layer accumulated above them during the Gondwana breakup. Some of the petroleum that was formed in the pre-salt layer has not leaked upward (see salt dome) to the post-salt layers above. This is especially common off the coast of Africa and Brazil. The amount of oil is not well known but is thought to be a significant fraction of world oil reserves. According to Petrobras, the oil and natural gas lie below an approximately 2000 m deep layer of salt, itself below an approximately 2000 m deep layer of rock under 2000-3000 m of the Atlantic. Drilling through the rock and salt to extract the pre-salt oil and gas is very expensive.

A pre-regulation terraced house is a terraced house built before 1875 Public Health Act in the United Kingdom usually in the period 1775 to 1875. It is an urban house-type built to house the poor. The 1875 Public Health Act imposed a duty on local authorities to regulate housing by the use of byelaws, and subsequently all byelaw terraced housing was required meet minimum, standards of build quality, ventilation, sanitation and population density.Almost all housing of this type has been demolished through successive waves of slum clearance.

POAT applies where an individual disposes of an asset but somehow retains the ability to use or enjoy it. POAT is never applicable when IHT is; therefore, the media and public have granted the issue little attention. POAT is also a retroactive tax: even if an action had no IHT repercussions at the time, POAT may be applied years after the action.

The PIC forms after uncoating of a viral particle after entry into the host cell. In the case of the human immunodeficiency virus (HIV), the PIC forms after the Reverse Transcription Complex (RTC) has reverse transcribed the viral RNA code into DNA code. The PIC consists of viral proteins (including Vpr, matrix and integrase), host proteins (including Barrier to autointegration factor 1) and the viral DNA. The PIC enters the cellular nucleus through the nuclear pore complex without disrupting the nuclear envelope, thus allowing HIV and related retroviruses to replicate in non-dividing cells. Following nuclear entry, the PIC's DNA payload may be integrated into the host DNA as a "provirus".

In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used.To build a key from shared secret, the key derivation function is typically used. Such systems almost always use symmetric key cryptographic algorithms. The term PSK is used in Wi-Fi encryption such as Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), where the method is called WPA-PSK or WPA2-PSK, and also in the Extensible Authentication Protocol (EAP), where it is known as EAP-PSK. In all these cases, both the wireless access points (AP) and all clients share the same key.The characteristics of this secret or key are determined by the system which uses it; some system designs require that such keys be in a particular format. It can be a password, a passphrase, or a hexadecimal string. The secret is used by all systems involved in the cryptographic processes used to secure the traffic between the systems.Crypto systems rely on one or more keys for confidentiality. One particular attack is always possible against keys, the brute force key space search attack. A sufficiently long, randomly chosen, key can resist any practical brute force attack, though not in principle if an attacker has sufficient computational power (see password strength and password cracking for more discussion). Unavoidably, however, pre-shared keys are held by both parties to the communication, and so can be compromised at one end, without the knowledge of anyone at the other. There are several tools available to help one choose strong passwords, though doing so over any network connection is inherently unsafe as one cannot in general know who, if anyone, may be eavesdropping on the interaction. Choosing keys used by cryptographic algorithms is somewhat different in that any pattern whatsoever should be avoided, as any such pattern may provide an attacker with a lower effort attack than brute force search. This implies random key choice to force attackers to spend as much effort as possible; this is very difficult in principle and in practice as well. As a general rule, any software except a Cryptographically secure pseudorandom number generator should be avoided.

Prehospital ultrasound is the specialized application of ultrasound by emergency responders, such as paramedics, to guide immediate care and first aid procedures. Like conventional ultrasound, it is a device that produces cyclic sound pressure to penetrate a medium (usually flesh, in this instance) and reveal details about the inner structure of the medium.

Pre-history of Polish lands

Pre-spawn mortality is a phenomenon where adult coho salmon, Oncorhynchus kisutch, die before spawning when returning to freshwater streams to spawn. This occurrence has been observed in much of the Puget Sound region of the Pacific Northwest. During fall migration, salmonids (trout and salmon) pass through urban watersheds which are contaminated with stormwater runoff. As the coho salmon pass through these waters, many will show symptoms of lethargy, loss of equilibrium and disorientation, and die within a few hours of showing these symptoms. These symptoms and behaviors are prevalent after rain events. Mortality often occurs before salmon have the opportunity to spawn, which is determined by cutting open female carcasses and observing for unfertilized eggs. Rates of pre-spawn mortality could impact the local salmon populations. Based on model projections, if rates continue, populations of coho salmon could become extinct within the next few decades.Weight of evidence suggests coho salmon pre-spawn mortality is due to exposure to stormwater runoff, although the exact contaminant or mixture that is responsible remains unknown. A negative correlation exists between the incidence of pre-spawn mortality and urban land use, specifically with the impervious surfaces, commercial property type, and local roads. Exposure to metals and petroleum hydrocarbons displayed some response to pre-spawn mortality, while exposure to pesticides, diseases, and water quality variables did not elicit this effect. This trend has not been observed in any other life history stage of the coho salmon nor in other salmon species in the Puget Sound region.

Pre-green is a golf term used to describe the grass between the green and the fairway. Around a foot in width, the grass is slightly shorter than that of the fairway, but longer than the green itself. The pre-green is commonly mistaken for the fringe. The fringe is the change in level from the green to the pre-green.

Pre-Health Sciences refers to the undergraduate courses to prepare American college students for admission in medical, dentistry, pharmacy, optometry, veterinary, and physical therapy schools, and for training as a physician assistant. In the United States, colleges have moved away from the impractical designation of students as "Pre-med" majors, as only a small percentage of applicants actually achieve admission into medical schools.
