摘要： A method of determining an analyte in the gaseous or vapour phase and in which a bioreceptor or biomimic is retained at an electrode. The bioreceptor or biomimic is preferably retained at a support at the electrode which comprises a solid or gel matrix of an electrolyte, especially organic salt electrolytes. Electrochemical detection of analytes in this way has several advantages over existing methods which rely on solution monitoring. For example gas sensors can be prepared for monitoring an analyte by the occurrence of a reaction with a bioreceptor or biomimic, in addition to monitoring the presence of toxins due to inhibition of the bioreceptor or biomimic reaction. Furthermore, the invention enables gas or vapour analyte monitoring with increased sensitivity and speed and greater stability of the sensors can be achieved. The invention also relates to novel media for carrying out bioelectrochemical reactions.

摘要： A phonograph comprising means for damping unwanted horizontal and vertical vibrations of a pick-up cartridge (3) on an arm (1). The damping means comprises a paddle (10) moving in a trough (11) of viscous fluid. The paddle is fixed to the arm (1) near the pick-up cartridge (3). The trough (11) is fixed during use to extend with clearance above a record surface.
The damping means thus acts to damp the pick-up cartridge, giving relatively low damping below 5 Hz, moderate damping between 5 Hz and 20 Hz and high damping above 20 Hz.
The resonance frequency between arm and stylus can be adjusted to be too high to be initiated by warps and too low to fall within the audio bandwidth, by using a counter-balance mass (7) comprising a plurality of individually removable interfitting annular rings.
Known phonograph damping, acting far from the pick-up cartridge, is subject to more complex vibration modes, e.g. torsional vibrations of the arm, at high frequencies.-

摘要： L'appareil décrit, qui sert à produire des décalages de fréquences de signaux par effet de diffusion de Brillouin stimulé, comprend une paire de fibres optiques (112, 113) ou une seule fibre à biréfringence élevée, qui sont soumises au rayonnement d'un faisceau laser de façon à produire des signaux rétrodiffusés par effet de diffusion de Brillouin stimulé, ainsi qu'un mélangeur (117) destiné à combiner les deux signaux rétrodiffusés pour produire une fréquence de battement à partir des signaux combinés.

摘要： Le procédé décrit, qui sert à déterminer la présence d'un analyte dans une solution organique ou micro-aqueuse, consiste à utiliser une électrode enzymatique sur laquelle est retenue une enzyme. L'enzyme peut être immobilisée de façon covalente sur l'électrode mais est de préférence retenue sur un support hydrophile (4) pouvant être relié à un conducteur électrique. La détection électrochimique d'analyte dans des solvants organiques ou micro-aqueux au moyen d'une électrode enzymatique présente plusieurs avantages par rapport aux procédés existants qui utilisent des solutions d'analytes aqueuses. Des composants ayant des hydrosolubilités faibles peuvent par exemple être détectés, la détection d'un analyte particulier peut être effectuée de façon plus sélective grâce au choix approprié du solvant, la stabilité thermique de l'enzyme peut être améliorée et les enzymes peuvent être aisément retenues sur l'électrode grâce à leur insolubilité dans le solvant organique ou micro-aqueux.
