Moving the plates in relation to one another changes their capacity for storing a charge, which in turn can generate a flow of electricity to fill up the increased capacity or drain off the excess charge as the capacity decreases. These minute electrical flows are detected by the circuitry of a capacitive keyboard. The small, somewhat gradual changes of capacity are amplified and altered so that they resemble the quick flick of a switch. 2, record 1, English, - capacitive%20keyboard

Cyanide toxicity is caused by the free cyanides(HCN and CN-) that inhibit cytochrome oxidase and thereby suppress aerobic respiration. Fish are the most susceptible organisms-sensitive species exhibit chronic and lethal effects at as low as 5-7 and 20-76 grams/liter, respectively. The toxicity of complex cyanides is usually, but not always, low, but the degradation products often include free cyanides which are toxic. Free cyanides readily degrade in the open environment but persist in groundwater. They do not bioaccumulate. Sublethal effects in fish include reduced reproductive capacity(decreased egg number and viability, and reduced embryo and larval survival), impaired swimming ability, altered growth, and hepatic necrosis. Free cyanides are phytotoxic at higher concentrations than those associated with adverse effects in fish. 2, record 2, English, - free%20cyanide

La sensibilité des organismes aquatiques est très variable vis à vis des différentes formes de cyanures, les doses toxiques variant de 0.01 à quelques mg/l. Une concentration en cyanure de sodium de 0.02mg/l est sans action visible sur les poissons. Cependant une concentration de 0.05 mg/l a une action mortelle sur une truite en cinq jours et une dose de 1 mg/l est mortelle en quelques heures. Cet exemple suffit à traduire la grande toxicité des cyanures libres vis à vis des poissons, mais aussi vis à vis des organismes inférieurs [...] 2, record 2, French, - cyanure%20libre

[...] le traitement du minerai nécessite l'utilisation de divers réactifs organiques et inorganiques qui sont susceptibles de se retrouver dans l'effluent de l'usine de traitement du minerai et, par la suite, dans celui du parc à résidus. Ainsi, dans les effluents des usines de traitement de métaux précieux, des cyanures libres et des complexes cyanurés (cyanures métalliques) ainsi que des produits de leur dégradation, tels que l'ammoniac, sont parfois observés à l'exutoire du parc à résidus. 4, record 2, French, - cyanure%20libre

El cianuro es extremadamente tóxico tanto para peces como para la salud humana, pues los cianuros inhiben reversiblemente la oxidación de las enzimas, deprimiendo el contenido de oxígeno en los tejidos. La toxicidad del cianuro y sus compuestos, es decir cianuro libre, los complejos cianuro-metal y los derivados del cianuro encontrados en efluentes de explotaciones auríferas varían desde muy bajos a exageradamente altos, donde el compromiso e interacción con el medioambiente se ve afectado como resultado de la disociación de estos complejos con generación del ácido cianhídrico y no por el complejo de cianuro estable en sí mismo, sin embargo debemos citar que los complejos cianuros de cobre y de plata han demostrado ser agudamente tóxicos para los peces. 2, record 2, Spanish, - cianuro%20libre

Model for regulatory enzymes--proposed by Koshland, Nemethy and Filmer--according to which the enzyme undergoes a series of conformational changes as the various ligands become bound to the enzyme. Different types of site interactions may occur of which symmetry preservation, as in the symmetry model, may be a special case. In general, however, the symmetry of the enzyme molecule is not conserved, since a subunit changes its conformation as a ligand becomes bound to it. The capacity of the enzyme to bind substrate, positive effectors, and negative effectors is altered by the conformational changes which the subunits undergo. 1, record 3, English, - sequential%20model

Two types of models have been proposed for the cooperative interactions of the subunits of hemoglobin, the sequential model proposed by D. E. Koshland and the symmetry model of J. Monod and his colleagues. These models are also applicable to allosteric enzymes having multiple subunits, which are assumed to occur in two different conformations. 2, record 3, English, - sequential%20model

Les interprétations moléculaires du mécanisme des modulations allostériques ont été très marquées par les travaux concernant les coopérativités dans la molécule d'hémoglobine. De nombreux modèles ont été proposés. Les deux plus importants sont le modèle séquentiel de Koshland et Atkinson, et le modèle concerté de Monod, Wyman et Changeux. (...) Leur point commun est de considérer que toute sous-unité catalytique fixant le modulateur (première molécule de substrat par exemple) subit une déformation (...) qui se transmet aux autres sous-unités, et modifie ainsi leur affinité pour le substrat : c'est l'expression même de la coopérativité. 1, record 3, French, - mod%C3%A8le%20s%C3%A9quentiel
