The ambient temperature and the nature of the storage fluids may well have significant effects upon the post-implantation behavior of venus autografts. A first step in the investigation of such effects is reported here. Experimental conditions have been set which approximate actual operating room procedures. Saphenous veins from dogs have been used as models in the experiments. After removal from the dogs the veins were kept for two hours under four different experimental conditions, viz at either 4°C or 23°C in either physiological saline or whole canine arterial blood. At the end of the two hours they were prepared for light and electron microscopy. Since no obvious changes or damage could be seen in the veins by light microscopy, even with the advantage of tissue specific stains, it was essential that the control of parameters for successful grafts be set by electron microscopy.

Monitoring of sea water condition is one of major requirements for carrying out the reliable ecological control of water environment. Monitoring networks contain such elements as sea buoys, beacons, etc. and are designated for measuringvarious hydrophysical parameters, including salinity of sea water. Development of specialized network and a separate buoy system for measuring thesea water salinity at different depths makes it possible to determine major regularities of processes of pollution and self-recovery of the sea waters. The article describes the scientific and methodological basics for development of this specialized network and questions of its optimal construction. It is well-known that at a depth of 30-45 m of the Caspian Sea salinity decreases and then at a depth of 45-60 m salinity is fully recovered. The mentioned changes of salinity at the relatively upper layer of sea waters is of special interest for studying the effect of ocean-going processes on the climate forming in the Caspian area. In terms of informativeness of measurements of surface waters salinity, the most informative is a layer ata 30-60 m depth, where inversion and recovery of salinity take place. It is shown that in most informative subrange of measurements, i. e. at a depth of 30-60 m optimization of regime of measurements complex should be carried out in order to increase the effectiveness of held researches. It is shown that at a depth of 35-50 m choice of the optimum regime of measurements makes it possible to obtain the maximum amount of information.

The article evaluates the reliability indicators of telecommunication system equipment, which can be represented by multi-mode objects of continuous and episodic use with a time reserve operating under conditions of a priori uncertainty. Particular attention is paid to consideration of the process of functioning of the system with a replenished time reserve. The telecommunication system includes an object represented by one structural element and used in different modes of operation. In each mode, the object can be used continuously or episodically (the object performs tasks that occur at random times), herewith only a certain part of its equipment is operating. The restoration of the facility's operation in each mode is based on the "quick" recovery scheme ("quick" recovery means that the repair time is much less than the average working time of the element between failures). Also, some cases of the transition of an object from one mode to another are considered, and the control system operates according to the method of sequential control of parameters. In this case, the system, after waiting mode, begins to analyze the first parameter of the monitored complex, then the second and so on. After analyzing the parameters, the system enters the waiting mode. These calculated ratios allow for a comprehensive assessment of the reliability of telecommunication equipment, taking into account the totality of the main factors that significantly affect the reliability of the equipment in real conditions of operation, make it possible to solve important practical problems which arise from the improvement of existing equipment and development of existing equipment.

The study has like objective, the modernize of integrated control management of aphids and cicades, vectors of wheat yellowishing and dwarf, by optimizing environment-agricture-sustainable development relations. The produced damages on wheat by aphids and cicades, justify the proposed research approaching. Pointed out by as on the last 30 years, the aphids dominante species Sitobion avenae, Schizaphis graminum, Metopolophium dirhodum, Rophalosiphum padi and the cicades: Psammotettix alienus, Macrosteles laevis, Javesella pellucida are registered and well knowed like vectors. Approaching a problem of economical importance and of actual scientific large interest, at national and European level, especially in conditions of profound agro-ecological changes brought by climatic warming and aridity, as the technologic and economic new conditions from agricultural area exploitations, the paper present complex researches, in systemic manner, concerning: knowledge of insects-vectors populations of viruses and micoplasma, which causes the cereals yellowishing, dwarf and nanisme; monitoring and settlement for the risk of this attack extending, with a increase potential, affecting the production of cereal grains cultures and which can causes sowing field compromise, especially of those find in monoculture or those sown early in September; the elaboration of a strategy for integrated agro-ecological control for these insects in Transylvania, through interdisciplinary research about the reductions methods of the attack in function of technological factors: selective insecticides, efficiency economic and ecologic, agro-technical methods and biotic factors: natural entomophagous; environmental protection, conservation and sustainable use of biodiversity.
