Constitutive Equation
In physics and engineering, a constitutive equation or constitutive relation is a relation between two or more physical quantities (especially kinetic quantities as related to kinematic quantities) that is specific to a material or substance or field, and approximates its response to external stimuli, usually as applied fields or forces. They are combined with other equations governing physical laws to solve physical problems; for example in fluid mechanics the flow of a fluid in a pipe, in solid state physics the response of a crystal to an electric field, or in structural analysis, the connection between applied stresses or loads to strains or deformations. Some constitutive equations are simply phenomenological; others are derived from first principles. A common approximate constitutive equation frequently is expressed as a simple proportionality using a parameter taken to be a property of the material, such as electrical conductivity or a spring constant.

Ecology
Ecology () is the natural science of the relationships among living organisms and their Natural environment, environment. Ecology considers organisms at the individual, population, community (ecology), community, ecosystem, and biosphere levels. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and is the study of abundance (ecology), abundance, biomass (ecology), biomass, and distribution of organisms in the context of the environment. It encompasses life processes, interactions, and adaptations; movement of materials and energy through living communities; ecological succession, successional development of ecosystems; cooperation, competition, and predation within and between species; and patterns of biodiversity and its effect on ecosystem processes. Ecology has practical applications in fields such as conservation biology, wetland management, natural resource m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inducible
Induction or inductive may refer to: Biology and medicine * Labor induction (of birth) * Induction chemotherapy, in medicine * Enzyme induction and inhibition * General anaesthesia Chemistry * Induction period, slow stage of a reaction * Inductive cleavage, in organic chemistry * Inductive effect, change in electron density * Asymmetric induction, preferring one stereoisomer over another Computing * Grammar induction * Inductive bias * Inductive probability * Inductive programming * Rule induction * Word-sense induction Mathematics * Backward induction in game theory and economics * Induced representation, in representation theory * Mathematical induction, a method of proof ** Strong induction ** Structural induction ** Transfinite induction *** Epsilon-induction * Parabolic induction Philosophy * Inductive reasoning, in logic Physics * Electromagnetic induction * Electrostatic induction * Forced induction, or turbocharging, of an engine Other uses * Ind ...

Constitutive Theory Of Statehood
A sovereign state is a state that has the highest authority over a territory. It is commonly understood that a sovereign state is independent. When referring to a specific polity, the term "country" may also refer to a constituent country, or a dependent territory. A sovereign state is required to have a permanent population, defined territory, a government not under another, and the capacity to interact with other sovereign states. In actual practice, recognition or non-recognition by other states plays an important role in determining the status of a country. Unrecognized states often have difficulty engaging in diplomatic relations with other sovereign states. History Since the end of the 19th century, almost the entire globe has been divided into sections (countries) with more or less defined borders assigned to different states. Previously, quite large plots of land were either unclaimed or deserted, or inhabited by nomadic peoples that were not organized into states. ...

Receptor (biochemistry)
In biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and Signal_transduction, transduce signals that may be integrated into biological systems. These signals are typically chemical messengers which bind to a receptor and produce physiological responses, such as a change in the electrophysiology, electrical activity of a cell. For example, GABA, an inhibitory neurotransmitter, inhibits electrical activity of neurons by binding to GABAA receptor, GABA receptors. There are three main ways the action of the receptor can be classified: relay of signal, amplification, or integration. Relaying sends the signal onward, amplification increases the effect of a single ligand (biochemistry), ligand, and integration allows the signal to be incorporated into another biochemical pathway. Receptor proteins can be classified by their location. Cell surface receptors, also known as transmembrane receptors, include ligand-gated ion channels, G prote ...
