Abstract: Le procédé a pour objet la détection du virus de la peste porcine africaine par analyse immunoenzymatique dans laquelle on utilise comme antigène la protéine majoritaire du virus (p72) obtenue par expression du gène qui la code. Le gène a été identifié par hybridation avec des sondes d'oligonucléotides déduites à partir d'informations de structure de la protéine purifiée. Un fois déterminée sa séquence de nucléotides, le gène fut introduit dans le vecteur d'expression pAR3038, obtenant ainsi le plasmide recombinant pS72a. Ce plasmide fut utilisé pour transformer la souche de E.coli BL21(DE3) qui, après induction avec IPTG, a permis la production à grande échelle de la protéine recombinante p72. La protéine fut purifiée par chromatographie liquide de haute résolution et fut utilisée directement dans des analyses antigène-anticorps avec des échantillons de sérum animal dans le but de diagnostiquer la maladie.

Abstract: A single crystal of semiconductor silicon can be sliced into wafers not by the conventional mechanical means but by a novel chemical means so that advantages are obtained in the reduced material loss by cutting and in the absence of any mechanically stressed layer in the surface of the wafer as sliced. The method comprises conducting electrolysis of an aqueous solution containing sulfuric and hydrofluoric acids with a fine platinum wire as the anode to evolve oxygen containing ozone on the anode surface while a single crystal of silicon is held in proximity to the wire anode so that the nascent oxygen formed from the ozone oxidizes silicon into silicon dioxide which as formed is dissolved away in the acidic medium to leave a groove in the single crystal. When the wire anode or the single crystal is continuously moved to keep a small distance between the wire anode and the groove bottom, the whole single crystal body is cut through to form a wafer.

Abstract: A variable compression ratio mechanism for a two cycle diesel engine embodying auxiliary exhaust passages (133) and auxiliary exhaust ports (132) that communicate with the cylinder (102) above the main exhaust ports (128) and in which control valves (134) are positioned for controlling the opening and closing of the auxiliary exhaust ports to change the effective compression ratio of the engine to minimize dead space between exhaust control valves and the auxiliary exhaust ports, the exhaust control valves are positioned in close proximity to the cylinder and comprise valve elements that operate in bores (136) that are disposed substantially parallel to the cylinder bore (103). Both rotary and reciprocating type valves are disclosed and various mechanisms are disclosed for interlinking the control valves for simultaneous operation. In addition, the positioning of the auxiliary exhaust passages permits the formation of a cooling jacket (155) between them that cools not only the auxiliary exhaust passages but also the control valves and the main exhaust passage (129). Embodiments are shown of adapted these principals to multiple cylinder engines and in which the main exhaust passages are formed in an acute angle to a plane containing the axes of the cylinder bores so as to permit a compact construction.

Abstract: A Doppler velocity spectrum produced by radial projection in a two-dimensional Fourier frequency domain is processed to suppress alias spectral terms. The projected spectrum is divided into windows using an iterative algorithm which centers the spectral mean. The window containing data samples which maximizes a weighted score based upon the width and maximal value of samples within the window is used to determine which window contains true spectra components. Spectral components in other windows are then suppressed.
