Barometer A device for measuring pressure. Battery Electrochemical cells that transform chemical energy into electricity. Base In chemistry, bases are substances that, in aqueous solution, release hydroxide (OH −) ions, are slippery to the touch, can taste bitter if an alkali, [50] change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote ...
Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics.Developmental bioelectricity refers to the endogenous ion fluxes, transmembrane and transepithelial voltage gradients, and electric currents and fields produced and sustained in living cells and tissues.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Manual nibbler, punch-and-die type. A nibbler, or nibblers, [1] is a tool for cutting sheet metal with minimal distortion. They may be used for nibbling.One type operates much like a punch and die, with a blade that moves in a linear fashion against a fixed die, removing small bits of metal and leaving a kerf approximately 6 mm (0.24 in) wide.
Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
Oxford Dictionary of Biology (often abbreviated to ODB) is a multiple editions dictionary published by the English Oxford University Press. With more than 5,500 entries, [ 1 ] [ 2 ] it contains comprehensive information in English on topics relating to biology , biophysics , and biochemistry . [ 3 ]
Metal whiskering is a phenomenon that occurs in electrical devices when metals form long whisker-like projections over time. Tin whiskers were noticed and documented in the vacuum tube era of electronics early in the 20th century in equipment that used pure, or almost pure, tin solder in their production.
