Preliminary Design Review
In the United States military integrated acquisition lifecycle the Technical section has multiple acquisition "Technical Reviews". Technical reviews and audits assist the acquisition and the number and types are tailored to the acquisition. Overall guidance flows from the Defense Acquisition Guidebook chapter 4, with local details further defined by the review organizations. Typical topics examined include adequacy of program/contract metrics, proper staffing, risks, budget, and schedule. In NASA's engineering design life cycle, design reviews are held for technical and programmatic accountability and to authorize the release of funding to a project. A design review provides an in-depth assessment by an independent team of discipline experts and managers that the design (or concept) is realistic and attainable from a programmatic and technical sense. Design review is also required of medical device developers as part of a system of design controls described in the US Food and D ...

Brachytherapy
Brachytherapy is a form of radiation therapy where a sealed radiation source is placed inside or next to the area requiring treatment. ''Brachy'' is Greek for short. Brachytherapy is commonly used as an effective treatment for cervical, prostate, breast, esophageal and skin cancer and can also be used to treat tumours in many other body sites. Treatment results have demonstrated that the cancer-cure rates of brachytherapy are either comparable to surgery and external beam radiotherapy (EBRT) or are improved when used in combination with these techniques. Brachytherapy can be used alone or in combination with other therapies such as surgery, EBRT and chemotherapy. Brachytherapy contrasts with unsealed source radiotherapy, in which a therapeutic radionuclide (radioisotope) is injected into the body to chemically localize to the tissue requiring destruction. It also contrasts to External Beam Radiation Therapy (EBRT), in which high-energy x-rays (or occasionally gamma-rays fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People's Democratic Republic
People's republic is an official title, usually used by some currently or formerly communist or left-wing states. It is mainly associated with soviet republics, socialist states following people's democracy, sovereign states with a democratic-republican constitution usually mentioning socialism, as well as some countries that do not fit into any of these categories. A number of the short-lived socialist states that formed during World War I and its aftermath called themselves people's republics. Many of these sprang up in the territory of the former Russian Empire which collapsed following the Russian Revolution of 1917. Decades later, following the Allied victory in World War II, the name "people's republic" was adopted by some of the newly established Marxist–Leninist states, mainly within the Soviet Union's Eastern Bloc. As a term, "people's republic" is associated with socialist states as well as communist countries adhering to Marxism–Leninism, although its use is not ...

Dead Reckoning
In navigation, dead reckoning is the process of calculating current position of some moving object by using a previously determined position, or fix, and then incorporating estimates of speed, heading direction, and course over elapsed time. The corresponding term in biology, used to describe the processes by which animals update their estimates of position or heading, is path integration. Dead reckoning is subject to cumulative errors. Advances in navigational aids that give accurate information on position, in particular satellite navigation using the Global Positioning System, have made simple dead reckoning by humans obsolete for most purposes. However, inertial navigation systems, which provide very accurate directional information, use dead reckoning and are very widely applied. Etymology The term "dead reckoning" was not originally used to abbreviate "deduced reckoning," nor is it a misspelling of the term "ded reckoning." The use of "ded" or "deduced reckoning" ...

Partido Para Sa Demokratikong Reporma
The Partido para sa Demokratikong Reporma ( en, Party for Democratic Reform; PDR), commonly known as Partido Reporma, is a political party in the Philippines. History It was founded by former Defense Secretary Renato de Villa when he left the ruling Lakas-NUCD after failing to get the nomination as the party's presidential candidate in the 1998 elections. He chose then Pangasinan governor Oscar Orbos as his running mate. The Lapiang Manggagawa (Workers' Party) forged an electoral alliance with Reporma for the 1998 elections, and the two parties contested in the elections as "Reporma–LM". However, De Villa and Orbos both lost to Joseph Estrada and Gloria Macapagal Arroyo, respectively. The alliance also failed to win seats in the 1998 Philippine Senate election. Haydee Yorac, Roy Señeres, and Rey Langit were among the candidates who failed to win a single seat in the Senate. In the 2004 elections, Reporma supported the candidacy of former Senator and Education Secretary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paintless Dent Repair
Paintless dent repair (PDR), also known as paintless dent removal, describes a method of removing minor dents from the body of a motor vehicle. A wide range of damage can be repaired using paintless dent repair as long as the paint surface is intact. Paintless dent repair may be used on both aluminum and steel panels. The most common practical use for paintless dent repair is the repair of hail Hail is a form of solid precipitation. It is distinct from ice pellets (American English "sleet"), though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets generally fal ... damage, door dings, minor creases, large dents and bodylines damage. The method can also be utilized to prepare a damaged panel for repainting by minimizing the use of body filler. This technique is currently known as "push to paint" or "push to prep". Limiting factors for a successful repair using paintless dent repair include the flex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magpul PDR
The Magpul PDR (Personal Defense Rifle) is a prototype bullpup-style 5.56×45mm NATO carbine unveiled by Magpul Industries in 2006. Although halted in development as of 2011 it has garnered some attention, largely due to its "futuristic" appearance. The system consists of a gas-operated bullpup carbine intended to replace some submachine guns, M9 pistols and M4 carbines while still offering the rapid fire and range of an M4 carbine in an ultra compact firearm. The PDR is one of the few personal defense weapons designed to use a standard caliber to simplify the logistics. The method of operation is a short stroke gas piston. It is striker-fired, features an ambidextrous ejection system, and ambidextrous controls. The PDR-C (Compact) features an FN P90-style pistol grip and ergonomics offering a more compact weapon, while the PDR-D (Direct) uses a more conventional pistol grip with vertical grip (similar to a Steyr TMP) and safety nub to keep users from injuring themselve ...

Photodissociation Region
In astrophysics, photodissociation regions (or photon-dominated regions, PDRs) are predominantly neutral regions of the interstellar medium in which far ultraviolet photons strongly influence the gas chemistry and act as the most important source of heat. They occur in any region of interstellar gas that is dense and cold enough to remain neutral, but that has too low a column density to prevent the penetration of far-UV photons from distant, massive stars. A typical and well-studied example is the gas at the boundary of a giant molecular cloud. PDRs are also associated with HII regions, reflection nebulae, active galactic nuclei, and Planetary nebulae. All the atomic gas and most of the molecular gas in the galaxy is found in PDRs. History The study of photodissociation regions began from early observations of the star-forming regions Orion A and M17 which showed neutral areas bright in infrared radiation lying outside ionised HII regions An H II region or HII region is ...

Conservation Easement
In the United States, a conservation easement (also called conservation covenant, conservation restriction or conservation servitude) is a power invested in a qualified private land conservation organization (often called a " land trust") or government (municipal, county, state or federal) to constrain, as to a specified land area, the exercise of rights otherwise held by a landowner so as to achieve certain conservation purposes. It is an interest in real property established by agreement between a landowner and land trust or unit of government. The conservation easement "runs with the land", meaning it is applicable to both present and future owners of the land. The grant of conservation easement, as with any real property interest, is part of the chain of title for the property and is normally recorded in local land records. The conservation easement's purposes will vary depending on the character of the particular property, the goals of the land trust or government unit, an ...
