Situation semantics examines linguistic meaning or the language /reality relationship, using a theory of situations to classify abstract objects & to describe meanings as relations between ...situations. A general description of situation semantics is followed by application of its principles to the examination of some ambiguities in English & Bulgarian. 8 References. B. Annesser Murray
A simple method for synthesis of S-sulfoxides of penicillanic acid and 6 alpha-bromo- and 6 alpha-chloropenicillanic acids is described. The S-sulfoxides were synthesized by the respective oxidation ...with 30% hydrogen peroxide at 0 degrees C in the absence of solvents. 1 mol of penicillanic acid and 1.5 to 2 mol of 6 alpha-bromo- or 6 alpha-chloropenicillanic acid were required. The yields of S-sulfoxides of 6 alpha-bromo- and 6 alpha-chloropenicillanic acids amounted to 55 and 50%, respectively, based on 6-aminopenicillanic acid. The yield of penicillanic acid S-sulfoxide was 80% based on penicillanic acid. The purity of the compounds was more than 95%.
Dustiness in the asbestos-cement production department of the "Vulkan" plant in Dimitrovgrad was studied. The assay included concentration, dispersion, substance composition, morphology, asbestos ...content. Two types dustiness were encountered: In the storage and mixing shops the aerosol contained 7 to 78 percent asbestos needles, free from agglomeration; in the moulding and turnery shops the asbestos content rangeal from 2 to 21 percent. Considerable part of the needles were amalgamated by the cement and could be detected only on electron-microscopic observation. The total amount of inhaled asbestos exceeded the amount inhaled at threshold concentration of 0.2 mg pure asbestos aerosol 9 times in the preparatory division and from 2 to 14 times in other shops. In the moulding shop the content was lower than the threshold one. Elevel cases of asbestosis were established: 3 in the preparatory, 4 in the turnery and 3 in other shops. In five cases there were pleural plaques in addition to the parenchymal changes. The minimal length of service to develop asbestosis was 13-14 years at the preparatory division (more free asbestos in the aerosol) and 20-21 years at the turnery shop (less, but agglomerated asbestos). Work with asbestos-cement exposes the workers to a serious risk of development of asbestosis. No principal difference was established in the biologic activity of the two aerosol types; there only is a difference in the degree of their aggressiveness.
Detailed investigations of the environment in asbestostextile industry ("Asbestos produce" plant in the town of Sevlievo) were carried out. The parameters determined were: overall dusting, amount of ...asbestos in aerosol, its mineral and disperse composition. Data on the degree of dusting in the plant for the period 1960--1976 were analyzed and summarized. Professiograms were elaborated, with chronometry and appraisal of the burden of the work operations. All workers were tested clinically and roentgenologically. The data obtained on the degree of dusting in the different departments were re-calculated as amount of inhaled asbestos, depending on how hard the work is, resp. the pulmonary ventilation. The actual risk of asbestos injury was highest in the carding department, followed by the preparatory and the spinning departments. A distinct correlation exists between the degree of professional risk, determined by the asbestos contaminations, and the clinical and laboratory findings.
