Nuclear Proliferation
Nuclear proliferation is the spread of nuclear weapons to additional countries, particularly those not recognized as List of states with nuclear weapons, nuclear-weapon states by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the ''Non-Proliferation Treaty'' or ''NPT''. Nuclear proliferation occurs through the spread of fissile material, and the technology and capabilities needed to produce it and to Nuclear weapon design, design and manufacture nuclear weapons. In a modern context, it also includes the spread of nuclear weapons to non-state actors. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare (including the so-called countervalue targeting of civilians), de-stabilize international relations, or infringe upon the principle of Sovereign state, state sovereignty. Conversely, supporters of deterrence theory arg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Weapon Proliferation
Many nations continue to research and/or stockpile chemical weapon agents despite numerous efforts to reduce or eliminate them. Most states have joined the Chemical Weapons Convention (CWC), which required the destruction of all chemical weapons by 2012. Twelve nations have declared chemical weapons production facilities and six nations have declared stockpiles of chemical weapons. All of the declared production facilities have been destroyed or converted for civilian use after the treaty went into force. CWC states with declared stockpiles Of the 193 nations that have signed the CWC, states listed below have also declared stockpiles and agreed to monitored disposal and verification. In some cases, chemical weapons were used in conflict. Both military targets and civilian populations have been affected. , only North Korea is confirmed to have remaining stockpiles of chemical weapons. * Iraq * Japan * Libya * Russia * Syria * United States Details by state Albania Albania, as ...

Missile Proliferation
A missile is an airborne ranged weapon capable of self-propelled flight aided usually by a propellant, jet engine or rocket motor. Historically, 'missile' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still recognized today with any unguided jet- or rocket-propelled weapons generally described as rocket artillery. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Missiles are also generally guided towards specific targets termed as guided missiles or guided rockets. Missile systems usually have five system components: targeting, guidance system, flight system, engine, and warhead. Missiles are primarily classified into different types based on firing source and target such as surface-to-surface, air-to-surface, surface-to-air and air-to-air missiles. Terminology Missile is derived from Latin "missilis" meaning "that may be thrown". Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small Arms Proliferation
The small arms trade (also called small arms proliferation and the small arms market) is the markets of both authorized and illicit small arms and light weapons (SALW), as well as their parts, accessories, and ammunition. Definition The arms trade, or small arms market, includes both authorized transfers of small arms and light weapons (and their parts, accessories, and bullets) and illicit transfers of such weapons. Small arms and light arms are those that can be transported by one or two people, or carried by pack animal or vehicles, ranging from firearms like pistols and light machine guns to man-portable air-defense systems (MPADS), mortars, and rocket-propelled grenades (RPGs). The trade occurs globally, but is concentrated in areas of armed conflict, violence, and organized crime. In terms of actions that are illicit, this trade involves the illegal trafficking of small arms and the exchange of money and drugs for small arms, which are all commodities that cross borders ar ...

Counter-proliferation
Counterproliferation refers to diplomatic, intelligence, and military efforts to combat the proliferation of weapons, including both weapons of mass destruction (WMD), long-range missiles, and certain conventional weapons. Measures to combat proliferation by analysing and preventing related financial transactions are referred to as counter-proliferation financing. Nonproliferation and arms control are related terms. In contrast to nonproliferation, which focuses on diplomatic, legal, and administrative measures to dissuade and impede the acquisition of such weapons, counterproliferation focuses on intelligence, law enforcement, and sometimes military action to prevent their acquisition.

License Proliferation
License proliferation is the phenomenon of an abundance of already existing and the continued creation of new software licenses for software and software packages in the FOSS ecosystem. License proliferation affects the whole FOSS ecosystem negatively by the burden of increasingly complex license selection, license interaction, and license compatibility considerations.OSI and License Proliferation on FOSSBazaar by Martin Michlmayr on August 21st, 2008. "Too many different licenses makes it difficult for licensors to choose: it's difficult to choose a good license for a project because there are so many. Some licenses do not play well together: some open source licenses do not inter-operate well with other open source licenses, making it hard to incorporate code from other projects. Too many lic ...

Data Proliferation
Data proliferation refers to the prodigious amount of data, structured and unstructured, that businesses and governments continue to generate at an unprecedented rate and the usability problems that result from attempting to store and manage that data. While originally pertaining to problems associated with paper documentation, data proliferation has become a major problem in primary and secondary data storage on computers. While digital storage has become cheaper, the associated costs, from raw power to maintenance and from metadata to search engines, have not kept up with the proliferation of data. Although the power required to maintain a unit of data has fallen, the cost of facilities which house the digital storage has tended to rise. Data proliferation has been documented as a problem for the U.S. military since August 1971, in particular regarding the excessive documentation submitted during the acquisition of major weapon systems. Efforts to mitigate data proliferation an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell Proliferation
Cell proliferation is the process by which ''a cell grows and divides to produce two daughter cells''. Cell proliferation leads to an exponential increase in cell number and is therefore a rapid mechanism of tissue growth. Cell proliferation requires both cell growth and cell division to occur at the same time, such that the average size of cells remains constant in the population. Cell division can occur without cell growth, producing many progressively smaller cells (as in cleavage of the zygote), while cell growth can occur without cell division to produce a single larger cell (as in growth of neurons). Thus, cell proliferation is not synonymous with either cell growth or cell division, despite these terms sometimes being used interchangeably. Stem cells undergo cell proliferation to produce proliferating "transit amplifying" daughter cells that later differentiate to construct tissues during normal development and tissue growth, during tissue regeneration after da ...

Wound Healing
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events is set into motion to repair the damage. This process is divided into predictable phases: blood clotting (hemostasis), inflammation, tissue growth ( cell proliferation), and tissue remodeling (maturation and cell differentiation). Blood clotting may be considered to be part of the inflammation stage instead of a separate stage. The wound-healing process is not only complex but fragile, and it is susceptible to interruption or failure leading to the formation of non-healing chronic wounds. Factors that contribute to non-healing chronic wounds are diabetes, venous or arterial disease, infection, and metabolic deficiencies of old age.Enoch, ...

Atypical Small Acinar Proliferation
In urologic pathology, atypical small acinar proliferation, is a collection of small prostatic glands, on prostate biopsy, whose significance is uncertain and cannot be determined to be benign or malignant. ASAP, generally, is ''not'' considered a pre-malignancy, or a carcinoma in situ; it is an expression of diagnostic uncertainty, and analogous to the diagnosis of ASCUS (atypical squamous cells of undetermined significance) on the Pap test. Association with adenocarcinoma On a subsequent biopsy, given the diagnosis of ASAP, the chance of finding prostate adenocarcinoma is approximately 40%; this is higher than if there is high-grade prostatic intraepithelial neoplasia (HGPIN). Management ASAP is considered an indication for re-biopsy; in one survey of urologist Urology (from Greek οὖρον ''ouron'' "urine" and ''-logia'' "study of"), also known as genitourinary surgery, is the branch of medicine that focuses on surgical and medical diseases of the urinary system an ...

Intravenous Atypical Vascular Proliferation
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth. It may also be used to administer medications or other medical therapy such as blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route of administration is also used for the consumpt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Massive Periretinal Proliferation
Proliferative vitreoretinopathy (PVR) is a disease that develops as a complication of rhegmatogenous retinal detachment. PVR occurs in about 8–10% of patients undergoing primary retinal detachment surgery and prevents the successful surgical repair of rhegmatogenous retinal detachment. PVR can be treated with surgery to reattach the detached retina but the visual outcome of the surgery is very poor. A number of studies have explored various possible adjunctive agents for the prevention and treatment of PVR, such as methotrexate, although none have yet been licensed for clinical use. PVR was originally referred to as massive vitreous retraction and then as massive periretinal proliferation. The name proliferative vitreo retinopathy was provided in 1989 by the Silicone Oil Study group. The name is derived from ''proliferation'' (by the retinal pigment epithelial and glial cells) and ''vitreo retinopathy'' to include the tissues which are affected, namely the vitreous humor (or s ...
