Neuroscientist
A neuroscientist (or neurobiologist) is a scientist who has specialised knowledge in neuroscience, a branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, Biological neural network, neural circuits, and glial cells and especially their Behavior, behavioral, Biology, biological, and psychological aspect in health and disease. Neuroscientists generally work as researchers within a college, university, government agency, or private Private industry, industry setting. In research-oriented careers, neuroscientists typically spend their time designing and carrying out scientific experiments that contribute to the understanding of the nervous system and its function. They can engage in basic or applied research. Basic research seeks to add information to our current understanding of the nervous system, whereas applied research seeks to address a specific problem, such as developing a treatment for a neurological disorder. ...

2003 Deaths
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Ordre National Du Mérite
The Ordre national du Mérite (; en, National Order of Merit) is a French order of merit with membership awarded by the President of the French Republic, founded on 3 December 1963 by President Charles de Gaulle. The reason for the order's establishment was twofold: to replace the large number of ministerial orders previously awarded by the ministries; and to create an award that can be awarded at a lower level than the Legion of Honour, which is generally reserved for French citizens. It comprises about 185,000 members; 306,000 members have been admitted or promoted in 50 years. History The Ordre national du Mérite comprises about 185,000 members; 306,000 members have been admitted or promoted in 50 years. Half of its recipients are required to be women. Defunct ministerial orders The Ordre national du Mérite replaced the following ministerial and colonial orders: Colonial orders * '' Ordre de l'Étoile d'Anjouan'' (1874) (Order of the Star of Anjouan) * ''Ordre du N ...

Bioelectricity
In developmental biology, bioelectricity refers to the regulation of cell, tissue, and organ-level patterning and behavior as the result of endogenous electrically mediated signaling. Cells and tissues of all types use ion fluxes to communicate electrically. The charge carrier in bioelectricity is the ion (charged atom), and an electric current and field is generated whenever a net ion flux occurs. Endogenous electric currents and fields, ion fluxes, and differences in resting potential across tissues comprise a signaling system. It functions alongside (in series and in parallel to) biochemical factors, transcriptional networks, and other physical forces to regulate the cell behavior and large-scale patterning during embryogenesis, regeneration, cancer, and many other processes. Overview Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics. Developmental bioelectricity refers to the endogenous ion f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It may increase the power significantly, or its main effect may be to boost the voltage or current (power, voltage or current amplifier). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a greater amplitude signal at its output. The ratio of output to input voltage, current, or power is termed gain (voltage, current, or power gain). An amplifier, by definition has gain greater than unity (if the gain is less than unity, the device is an attenuator). An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are widely used in almost all electronic equipment. Amplifiers can be categorize ...
