Abstract:
The invention relates to a method for measuring the real temperature of a hot spot in an oil-containing electric apparatus, such as a power transformer. The electric apparatus is operated in predetermined and changeable operating conditions. The method comprises using one or more chemical compounds or tracers present and soluble in the oil. Each tracer is capable of conversion at a given temperature in order to form a residue such as a soluble gas. Due to the presence of residue in the oil, the operator can determine in which predetermined operational conditions the hot spot has been reached, and derive therefrom the hot spot for a given condition. The different compounds used include diazoic compounds, carbonyl metals, dyes, pigments, liquid crystals or albumins. The method can also be used for checking the quality of the marketed apparatus and estimating the lifespan thereof.

Abstract:
An azole derivative represented by general formula (I) or a pharmaceutically acceptable salt thereof, having both of a leukotriene antagonistic effect and a thromboxane A2 antagonistic effect and being useful in preventing or treating allergic diseases, ischemic heart diseases or ischemic brain diseases, and a medicinal composition containing the same as the active ingredient, wherein R?1 and R2¿ may be the same or different and represent each hydrogen, cycloalkyl, etc., or R?1 and R2¿ together with (a) may form a fused ring (b) or (c) which may be substituted by optionally substituted lower alkyl, amino, etc.; R?3, R6, R7 and R8¿ may be the same or different and represent each hydrogen, amino, etc.; R4 represents cyano, tetrazolyl, -COOR9, etc.; R5 represents hydrogen or lower alkyl; D represents optionally substituted lower alkylene; X and Z may be the same or different and represent each oxygen or sulfur; Y represents -N= or -CH=; A represents -O-B-, -B-O-, -S-B-, -B-S- or -B- (B being lower alkylene or lower alkenylene); and n is 0, 1 or 2.
Abstract:
The present invention is directed to novel arginine alpha-keto-amide derivatives, their pharmaceutically acceptable salts and compositions thereof which are useful as antithrombotic agents in mammals and also the use of these compounds as antithrombotic agents. Also, described are methods of using these inhibitors as inhibitors of coagulation proteases and as therapeutic agents for disease states characterized by abnormal thrombus formation and/or disorders of the blood coagulation process. Further described herein are compounds useful as intermediates in the preparation of thesse compounds.
