Primer (film)
''Primer'' is a 2004 American independent psychological science fiction film about the accidental discovery of time travel. The film was written, directed, produced, edited and scored by Shane Carruth, who also stars with David Sullivan. ''Primer'' is of note for its extremely low budget, experimental plot structure, philosophical implications, and complex technical dialogue, which Carruth, a college graduate with a degree in mathematics and a former engineer, chose not to simplify for the sake of the audience. The film collected the Grand Jury Prize at the 2004 Sundance Film Festival, before securing a limited release in the United States, and has since gained a cult following. Plot Two engineers, Aaron and Abe, supplement their day jobs with entrepreneurial tech projects, working out of Aaron's garage. During one such research effort, involving electromagnetic reduction of objects' weight, the two men accidentally discover an 'A-to-B' causal loop side-effect: objects left ...

Primer (paint)
A primer () or undercoat is a preparatory coating put on materials before painting. Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted. Composition A primer consists of synthetic resin, solvent and additive agent while some primers contain polyethylene (plastic), for better durability. Use Primer is a paint product that allows finishing paint to adhere much better than if it were used alone. It is designed to adhere to surfaces and to form a binding layer that is better prepared to receive the paint. Compared to paint, a primer is not intended to be used as the outermost durable finish and can instead be engineered to have improved filling and binding properties with the material underneath. Sometimes this is achieved by chemistry, as in the case of aluminum primer, but more often this is achieved through controlling the primer's physical properties such as its porosity, tackiness ...

Trap Primer
A trap primer (or trap seal primer) is a plumbing device or valve that adds water to traps. The water seals in traps are needed to prevent sewer gases from entering buildings, but because this water is exposed to the air, it is subject to evaporation over time in infrequently used floor drains, leading to the release of sewer gas into the environment. The trap primer mitigates this problem by injecting water, either directly or indirectly, into the trap to maintain the water seal indefinitely. Building codes may require trap primers for traps in certain locations or situations, usually those in which industry experience has shown that they are likely to dry out. The most common requirement is for basement floor drains, which are only used when the basement floods. Sometimes they are also installed in locations where the plumbing code does not require a primer because of a high probability of the trap drying out, but because of a nearby ignition source and the explosion hazard in ...

Money-creation Primer
Money creation, or money issuance, is the process by which the money supply of a country, or of an economic or monetary region,Such as the Eurozone or ECCAS is increased. In most modern economies, money creation is controlled by the central banks. Money issued by central banks is termed base money. Central banks can increase the quantity of base money directly, by engaging in open market operations. However, the majority of the money supply is created by the commercial banking system in the form of bank deposits. Bank loans issued by commercial banks that practice fractional reserve banking expands the quantity of broad money to more than the original amount of base money issued by the central bank. Central banks monitor the amount of money in the economy by measuring monetary aggregates (termed broad money), consisting of cash and bank deposits. Money creation occurs when the quantity of monetary aggregates increase.For example, in the United States, money supply measured as M2 ...

Primer (gasoline Engine)
A petrol engine (gasoline engine in American English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as ''E10'' and ''E85''). Most petrol engines use spark ignition, unlike diesel engines which typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also been produced using the Miller cycle and Atkinson cycle. Layout Most petrol-powered piston engines are straight engines or V engines. However, flat engines, W engines and other layouts are sometimes used. Wankel engines are classified by the number of rotors used. Compression ratio Cooling Petrol engines are either air-cooled or water-cooled. Ignition Petrol eng ...

Primer-E Primer
Plymouth Routines In Multivariate Ecological Research (PRIMER) is a statistical package that is a collection of specialist univariate, multivariate, and graphical routines for analyzing species sampling data for community ecology. Types of data analyzed are typically species abundance, biomass, presence/absence, and percent area cover, among others. It is primarily used in the scientific community for ecological and environmental studies. Multivariate routines include: *grouping (CLUSTER) *sorting (MDS) *principal component identification (PCA) *hypothesis testing (ANOSIM) *sample discrimination (SIMPER) *trend correlation (BEST) *comparisons (RELATE) *diversity, dominance, and distribution calculating * Permutational multivariate analysis of variance (PERMANOVA) Routines can be resource intensive due to their non-parametric and permutation-based nature.

Sylvester Primer
Sylvester Primer (1842–1912) was an American linguist and philologist known for his pioneering work in 1887 on the dialect of the European-American residents of Charleston, South Carolina. He published language studies in both English and German, and an 1880 work in German was reprinted in 2010.

Long Primer
In typography, the point is the smallest unit of measure. It is used for measuring font size, leading, and other items on a printed page. The size of the point has varied throughout printing's history. Since the 18th century, the size of a point has been between 0.18 and 0.4 millimeters. Following the advent of desktop publishing in the 1980s and 1990s, digital printing has largely supplanted the letterpress printing and has established the DTP point (DeskTop Publishing point) as the ''de facto'' standard. The DTP point is defined as of an international inch () and, as with earlier American point sizes, is considered to be of a pica. In metal type, the point size of the font describes the height of the metal body on which the typeface's characters were cast. In digital type, letters of a font are designed around an imaginary space called an '' em square''. When a point size of a font is specified, the font is scaled so that its em square has a side length of that particu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
