Priming (agriculture)
Nano seed priming in botany and agriculture is a form of seed A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiospe ... planting preparation in which the seeds are pre-soaked in nanoparticle solution. Seeds are considered to be an important part of crop life cycle as it influences the propagation of critical phases like germination and dormancy. Seed priming before sowing is considered to be one of the promising ways to provide value-added solutions to maximize the natural potential of seed to set the plant for maximum yield potential with respect to both quality and quantity.

Priming (immunology)
Priming is the first contact that antigen-specific T helper cell precursors have with an antigen. It is essential to the T helper cells' subsequent interaction with B cells to produce antibodies. Priming of antigen-specific naive lymphocytes occurs when antigen is presented to them in immunogenic form (capable of inducing an immune response). Subsequently, the primed cells will differentiate either into effector cells or into memory cells that can mount stronger and faster response to second and upcoming immune challenges. Priming of naïve T cells requires dendritic cell antigen presentation. Priming of naive CD8 T cells generates cytotoxic T cells capable of directly killing pathogen-infected cells. CD4 cells develop into a diverse array of effector cell types depending on the nature of the signals they receive during priming. CD4 effector activity can include cytotoxicity, but more frequently it involves the secretion of a set of cytokines that directs the target cell to ...

Priming (media)
The priming theory states that Multimedia, media images association (psychology), stimulate related thoughts in the minds of audience members.Straubhaar, LaRose, Davenport. Grounded in cognitive psychology, the theory of media priming is derived from the associative network model of human memory, in which an idea or concept is stored as a node in the network and is related to other ideas or concepts by semantic paths. Priming refers to the activation of a node in this network, which may serve as a filter, an interpretive frame, or a premise for further information processing or judgment formation. General aggression model The general aggression model (GAM) integrates the priming theory with the social learning theory to describe how previously learned violent behavior may be triggered by thoughts, emotions, or physiological states provoked by media exposure. However, the GAM has come under considerable criticism in recent years regarding underlying and unproven assumptions and poo ...

Priming (microbiology)
Priming or a "priming effect" is said to occur when something that is added to soil or compost affects the rate of decomposition occurring on the soil organic matter (SOM), either positively or negatively. Organic matter is made up mostly of carbon and nitrogen, so adding a substrate containing certain ratios of these nutrients to soil may affect the microbes that are mineralizing SOM. Fertilizers, plant litter, detritus, and carbohydrate exudates from living roots, can potentially positively or negatively prime SOM decomposition. See also * Soil carbon * Nutrient cycle * Soil chemistry * Soil biology * Environmental microbiology * Microbial biodegradation Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e ...

Priming (psychology)
Priming is a phenomenon whereby exposure to one stimulus influences a response to a subsequent stimulus, without conscious guidance or intention. The priming effect refers to the positive or negative effect of a rapidly presented stimulus (priming stimulus) on the processing of a second stimulus (target stimulus) that appears shortly after. Generally speaking, the generation of priming effect depends on the existence of some positive or negative relationship between priming and target stimuli. For example, the word ''nurse'' is recognized more quickly following the word ''doctor'' than following the word ''bread''. Priming can be perceptual, associative, repetitive, positive, negative, affective, semantic, or conceptual. Priming effects involve word recognition, semantic processing, attention, unconscious processing, and many other issues, and are related to differences in various writing systems. Research, however, has yet to firmly establish the duration of priming effects, yet th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Priming (steam Locomotive)
Priming (foaming in North America) is a condition in the boiler of a steam locomotive in which water is carried over into the steam delivery. It may be caused by impurities in the water, which foams up as it boils, or simply too high a water level. It is harmful to the valves and pistons, as lubrication is washed away, and can be dangerous as any water collecting in the cylinders is not compressible and if trapped may fracture the cylinder head or piston. Causes The most frequent cause is running the locomotive with too high a level of water in the boiler and is most apparent when the regulator is opened sharply or steam demand is high. Thus, sensible locomotive management by the operators will help to prevent the occurrence. The phenomenon is particularly evident in areas of impure water, where boiled water creates a foam, or a mist of droplets, filling the space that collects steam at the top of the boiler, to be drawn down the steam collector pipe in the form of slugs of w ...

Priming (structural)
Structural priming is a form of positive priming, in that it induces a tendency to repeat or more easily process a current sentence that is similar in structure to a previously presented prime. It is a phenomenon studied in the field of psycholinguistics. J. Kathryn Bock introduced it in 1986,.Bock, J.K. (1986). Syntactic persistence in language production. ''Cognitive Psychology'', 18, 355-387. Several paradigms exist to elicit structural priming. Structural priming persists cross-linguistically. One specific form of structural priming is syntactic priming. Eliciting structural priming ;Picture description Bock introduced a picture description task to investigate this phenomenon. In the study phase, at their own pace, participants read a list of sentences and observe a set of pictures. All these pictures describe events including an agent, patient, and theme. Half of the agents pictured are humans and the other half inanimate objects. This phase of the experiment was performed i ...

Priming Beta-ketosynthase
Ketoacyl synthases (KSs) catalyze the condensation reaction of acyl-CoA or acyl-acyl ACP with malonyl-CoA to form 3-ketoacyl-CoA or with malonyl-ACP to form 3-ketoacyl-ACP. This reaction is a key step in the fatty acid synthesis cycle, as the resulting acyl chain is two carbon atoms longer than before. KSs exist as individual enzymes, as they do in type II fatty acid synthesis and type II polyketide synthesis, or as domains in large multidomain enzymes, such as type I fatty acid synthases (FASs) and polyketide synthases (PKSs). KSs are divided into five families: KS1, KS2, KS3, KS4, and KS5. Multidomain enzyme systems Fatty acid synthase Fatty acid synthase (FAS) is the enzyme system involved in de novo fatty acid synthesis. FAS is an iterative multienzyme consisting of several component enzymes, one of which is ketoacyl synthase. There are two types of FASs: type I and type II. Type I FASs are highly integrated multidomain enzymes. They contain discrete functional domains respo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pump
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: ''direct lift'', ''displacement'', and ''gravity'' pumps. Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis. When a casing contains only one revolving impeller, it is called a single-stage pump. Whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Priming The Pump
In economics, stimulus refers to attempts to use monetary policy or fiscal policy (or stabilization policy in general) to stimulate the economy. Stimulus can also refer to monetary policies such as lowering interest rates and quantitative easing. A stimulus is sometimes colloquially referred to as "priming the pump" or "pump priming". Concept During a recession, production and employment are far below their sustainable potential due to lack of demand. It is hoped that increasing demand will stimulate growth and that any adverse side effects from stimulus will be mild. Fiscal stimulus refers to increasing government consumption or transfers or lowering taxes, increasing the rate of growth of public debt. Supporters of Keynesian economics assume the stimulus will cause sufficient economic growth to fill that gap partially or completely via the multiplier effect. Monetary stimulus refers to lowering interest rates, quantitative easing, or other ways of increasing the amount of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Priming Sugar
Homebrewing is the brewing of beer or other alcoholic beverages on a small scale for personal, non-commercial purposes. Supplies, such as kits and fermentation tanks, can be purchased locally at specialty stores or online. Beer was brewed domestically for thousands of years before its commercial production, although its legality has varied according to local regulation. Homebrewing is closely related to the hobby of ''home distillation'', the production of alcoholic spirits for personal consumption; however home distillation is generally more tightly regulated. History Beer has been brewed domestically throughout its 7,000-year history, beginning in the Neolithic period in Mesopotamia (modern Iraq), Egypt and China. It seems to have first developed as thick beers; during this time meads, fruit wines and rice wines were also developed. Women brewers dominated alcohol production on every occupied continent until commercialization and industrialization of brewing occur ...
