Response of Colorado potato beetles,Leptinotarsa decemlineata (Say), to volatile components of tansy,Tanacetum vulgare

The responses of Colorado potato beetle,Leptinotarsa decemlineata (Say), to volatile components of tansy,Tanacetum vulgare L., were investigated in order to establish a chemical basis for observed reduction in beetle populations when potatoes,Solanum tuberosum L., were interplanted with tansy. Colorado potato beetles exhibited avoidance behavior to tansy oil, volatiles from intact tansy plants, a hydrocarbon fraction of tansy oil, obtained by fractionation on alumina, and five of the 13 known components of tansy oil that were tested. One constituent of tansy oil, -pinene, attracted beetles.     

The morbidity indices of subjects with incorporated radioactive iodine

With the purpose of detecting long-term somatic effects of incorporated iodine, an analysis was performed of health disorders in those subjects (n = 1040) who received 131 I in therapeutic dosages 25 to 30 years ago. Discordances in pituitary-thyroid- and pituitary-adrenal axes were found to result in excessive metabolic-degenerative and vegetovascular type morbidity rates compared with the general population. Mortality index exceeds that of in the population 2.1-fold. No one of the deceased had reached the average length of human life. Halt the cases died of ischemic heart disease, 6 patients developed carcinoma of endocrine organs; these were all females, who had taken radioactive iodine prior to the age of 30 years. Thus, in remote time periods after incorporation, there develop a number of those disorders leading ultimately to reduction of the length of human life, which is believed to be one of the universal effects of irradiation.     

The assessment of functional status of blood platelets in patients infected with Giardia intestinalis after anti-parasitic treatment

Platelets are involved in anti-parasitic mechanisms. This question is poorly recognized. Platelets may exhibit this function only after activation. Therefore we conducted this study measuring some morphological parameters of these cells which reflect activation of platelets. The experiments were done on 30 patients infected with Giardia intestinalis. Diagnosis was supported on finding trophozoits in bile, cysts and GSA 65-protein in feces. We have found some decrease of blood platelets count and normalization after anti-parasitic treatment. In the line with this observation is platelet crit. A slight change was noted in mean platelet volume before and after treatment if we compare to controls. The same observation concern platelet anisocytosis index. Nearly two-fold decrease in the count of large platelets was observed before and after treatment 3.77% and 2.07%. Our general conclusion is, the parasite is able to activate the platelets and anti-parasitic treatment normalize these changes.     

A method for the complex chemicothermal treatment of machine parts and tools

Today the service conditions of the majority of machine parts require not only high tribological properties, but also high corrosion resistance. This combination of properties is obtained by a chemicothermal treatment (CTT) that includes the nitriding and oxidizing of the surface. Development of this method resulted in an ONS (O-oxygen, N-nitrogen, S -sulfur) method that consists of nitriding, oxidizing, and surface saturation with sulfur, nitrogen, and carbon. This paper is devoted to the properties of various steels after ONS.Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 2, pp. 9 – 11, February, 1995.     

Formation of individual somatotype parameters and features of constitutional organization in 7-12-year-old boys (longitudinal)

Individual somatotype parameters and peculiarities of constitution in 7-12 years boys were evaluated in the present investigation. The age range studied was shown to be divided on 3 stages. Regular growth processes with the prevalence of "infantal" proportions occur at the age of 7-9. Signs of definite constitutional type are expressed yet insufficiently. The age of 10-11 is transitional which shows in delay of muscle growth. At the age of 11-12 prepubescent sets in, during which features of constitution types and appropriate somatotype parameters are distinctly manifested.     

Mercury emissions to the atmosphere from anthropogenic sources in Europe in 2000 and their scenarios until 2020

The paper reviews the current state of knowledge regarding European emissions of mercury and presents estimates of European emissions of mercury to the atmosphere from anthropogenic sources for the year 2000. This information was then used as a basis for Hg emission scenario development until the year 2020. Combustion of coal in power plants and residential heat furnaces generates about half of the European emissions being 239 tonnes. The coal combustion is followed by the production of caustic soda with the use of the Hg cell process (17%). Major points of mercury emission generation in the mercury cell process include: by-product hydrogen stream, end box ventilation air, and cell room ventilation air. This technology is now being changed to other caustic soda production technologies and further reduction of Hg emissions is expected in this connection. The third category on the list of the largest Hg emitters in Europe is cement production (about 13%). The largest emissions were estimated for Russia (the European part of the country), contributing with about 27% to the European emissions, followed by Poland, Germany, Spain, Ukraine, France, Italy and the United Kingdom. Most of these countries use coal as a major source of energy in order to meet the electricity and heat demands. In general, countries in the Central and Eastern Europe generated the main part of the European emissions in 2000. Emission reductions between 20% and 80% of the 2000 emission amounts can be obtained by the year 2020, as estimated by various scenarios.     

Multiorgan changes in AIDS in a reported case

The clinical course of HIV infection and results of autopsy examination in 49 years old patient was shown. The attention was paid to difficulties of diagnosis of opportunistic infections in a patients with advanced HIV disease. Variety of infectious factors, that could affect a patient with significant immunodeficiency was outlined.
