The People's Republic Of Animation
The People's Republic of Animation (PRA) is an animation studio based in Adelaide, Australia. It began as a creator of music videos for Australian bands in 2003, and has since created award-winning short films and TV commercials, and developed feature films. Foundation As 14-year-olds, in 1996, PRA founders Eddie White, James Calvert & Hugh Nguyen began experimenting with a Super 8 film camera under the name of ‘Dabble Animation’. Their first short film ''Natural Born Animators'' (1998) was made two years later and achieved some national and international festival success on the student film circuit, including a selection at the Student Animation Festival in Ottawa, Ontario, Canada. In 2000 White renamed the team 'The People's Republic of Animation', a name coined after he flipped through an old Funk & Wagnall's encyclopedia looking for titles and saw the heading 'The People's Republic of China' and liked the empire-like and grand connotations it had.

Pest Risk Analysis
Pest risk analysis (PRA) is a form of risk analysis conducted by regulatory plant health authorities to identify the appropriate phytosanitary measures required to protect plant resources against new or emerging pests and regulated pests of plants or plant products. Specifically pest risk analysis is a term used within the International Plant Protection Convention (IPPC) (Article 2.1) and is defined within the glossary of phytosanitary terms. as "the process of evaluating biological or other scientific and economic evidence to determine whether an organism is a pest, whether it should be regulated, and the strength of any phytosanitary measures to be taken against it". In a phytosanitary context, the term plant pest, or simply pest, refers to any species, strain or biotype of plant, animal or pathogenic agent injurious to plants or plant products and includes plant pathogenic bacteria, fungi, fungus-like organisms, viruses and virus like organisms, as well as insects, mites, nematod ...

Prahran Railway Station
Prahran railway station (/pɛ'ræn) is a commuter railway station on the Sandringham line, which is part of the Railways in Melbourne, Melbourne railway network. It serves the south-eastern suburb of Prahran, Victoria, Prahran, in Melbourne, Victoria, Australia. Prahran station is a ground level host station, featuring two side platforms. It opened on 22 December 1860. Initially opened as Greville Street, the station was given its current name of Prahran on 1 January 1867. History Prahran station opened on 22 December 1860, when the railway line from South Yarra railway station, South Yarra was extended to Windsor railway station, Melbourne, Windsor. Like the suburb itself, the station was named from the Indigenous Australians, Indigenous Australian Aboriginal languages, word ‘purraran’, believed to mean ‘almost surrounded by water’. In 1962, boom barriers replaced interlocking, interlocked gates at the Greville Street level crossing, located at the Rail directions#Up ...

Participatory Rural Appraisal
Participatory rural appraisal (PRA) is an approach used by non-governmental organizations (NGOs) and other agencies involved in international development. The approach aims to incorporate the knowledge and opinions of rural people in the planning and management of development projects and programmes. Origins The philosophical roots of participatory rural appraisal techniques can be traced to activist adult education methods such as those of Paulo Freire and the study clubs of the Antigonish Movement. In this view, an actively involved and empowered local population is essential to successful rural community development. Robert Chambers, a key exponent of PRA, argued that the approach owes much to "the Freirian theme, that poor and exploited people can and should be enabled to analyze their own reality." By the early 1980s, there was growing dissatisfaction among development experts with both the reductionism of formal surveys, and the biases of typical field visits. In 1983, R ...

Sender ID
Sender ID is an historic anti- spoofing proposal from the former MARID IETF working group that tried to join Sender Policy Framework (SPF) and Caller ID. Sender ID is defined primarily in Experimental RFC 4406, but there are additional parts in RFC 4405, RFC 4407 and RFC 4408. Principles of operation Sender ID is heavily based on SPF, with only a few additions. Sender ID tries to improve on SPF: SPF does not verify the header addresses (of which there can be more than one) that indicate the claimed sending party. One of these header addresses is typically displayed to the user and may be used to reply to emails. These header addresses can be different from the address that SPF tries to verify; that is, SPF verifies only the "MAIL FROM" address, also called the envelope sender. However, there are many similar email header fields that all contain sending party information; therefore Sender ID defines in RFC 4407 a Purported Responsible Address (PRA) as well as a set of heurist ...

Progressive Retinal Atrophy
Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, it is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness. The condition in nearly all breeds is inherited as an autosomal recessive trait, with the exception of the Siberian Husky (inherited as an X chromosome linked trait) and the Bullmastiff (inherited as an autosomal dominant trait). There is no treatment. Types of PRA In general, PRAs are characterised by initial loss of rod photoreceptor cell function followed by that of the cones and for this reason night blindness is the first significant clinical sign for most dogs affected with PRA. As other retinal disorders, PRA can be divided into either dysplastic disease, where the cells develop abnormally, and degenerative, where the cells develop normally but then degenerate during the dog's lifetime. ...

Progesterone Receptor A
The progesterone receptor A (PR-A) is one of three known isoforms of the progesterone receptor (PR), the main biological target of the endogenous progestogen sex hormone progesterone. The other isoforms of the PR include the PR-B and PR-C. PR-A is 164 residues shorter than PR-B in humans and anywhere from 128-165 residues shorter in other organisms. Each isoform binds its natural ligand, progesterone, but also demonstrates the ability to bind a number of other agonists including norethindrone, a synthetic progestin. Expression and overexpression PR-A and PR-B are generally expressed in equal ratios, but PR-A is expressed in larger amounts in uterine stromal cells normally. A spike in PR-A expression in the myometrium has been observed to initiate parturition in placental mammals. PR-A is the isoform most commonly observed to be overexpressed in human breast cancer and patients with PR-A rich carcinomas, as opposed to patients with PR-B rich carcinomas, have faster recurrence ...

Probabilistic Risk Assessment
Probabilistic risk assessment (PRA) is a systematic and comprehensive methodology to evaluate risks associated with a complex engineered technological entity (such as an airliner or a nuclear power plant) or the effects of stressors on the environment (probabilistic environmental risk assessment, or PERA). Risk in a PRA is defined as a feasible detrimental outcome of an activity or action. In a PRA, risk is characterized by two quantities: #the magnitude (severity) of the possible adverse consequence(s), and #the likelihood (probability) of occurrence of each consequence. Consequences are expressed numerically (e.g., the number of people potentially hurt or killed) and their likelihoods of occurrence are expressed as probabilities or frequencies (i.e., the number of occurrences or the probability of occurrence per unit time). The total risk is the expected loss: the sum of the products of the consequences multiplied by their probabilities. The spectrum of risks across classes ...

Primitive Recursive Arithmetic
Primitive recursive arithmetic (PRA) is a quantifier-free formalization of the natural numbers. It was first proposed by Norwegian mathematician , as a formalization of his finitistic conception of the foundations of arithmetic, and it is widely agreed that all reasoning of PRA is finitistic. Many also believe that all of finitism is captured by PRA, but others believe finitism can be extended to forms of recursion beyond primitive recursion, up to ε0, which is the proof-theoretic ordinal of Peano arithmetic.; however, Feferman calls this extension "no longer clearly finitary". PRA's proof theoretic ordinal is ωω, where ω is the smallest transfinite ordinal. PRA is sometimes called ''Skolem arithmetic'', although that has another meaning, see Skolem arithmetic. The language of PRA can express arithmetic propositions involving natural numbers and any primitive recursive function, including the operations of addition, multiplication, and exponentiation. PRA cannot e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Positive Relative Accommodation
Positive relative accommodation (PRA) in biology, is a measure of the maximum ability to stimulate eye accommodation while maintaining clear, single binocular vision. This measurement is typically obtained by an orthoptist, ophthalmologist or optometrist during an eye examination using a phoropter. After the patient's distance correction is established, she or he is instructed to view small letters on a card 40 cm from the eyes. The examiner adds lenses in −0.25 diopter increments until the patient first reports that they become blurry. The total value of the lenses added to reach this point is the PRA value. High PRA values (>= 3.50 diopters) are considered to be diagnostic of disorders involving accommodative excess. Those with accommodative insufficiency typically have PRA values below −1.50 diopters.
