We report new data on ground beetles from two mountainous regions of the Chechen Republic (Sharoi and Shatoi regions). The specimens were collected in five biotopes of two natural zones (mountain - forest, mountain - meadow zones). A total of 2213 specimens of ground beetles belonging to 56 species of 16 genera were collected. An annotated list of the newly collected species with indications of their geographical allocation and corresponding biotopes, as well as the number of specimens collected, are presented in the paper.

The paper examines the nomenclature and species structure of the poorly-known and rarely mentioned taxon Achillea micranthoides Klokov. The specimens of this species are measured using the materials collected by the authors in the west of the Orenburg region and using available herbarium materials (MHA, MW). The data are analyzed by the method of variance analysis in the statistical program PAST. 3.01. The studies show that A. micranthoides differs in a number of characteristics from other taxons Achillea L., which occur in the same biotopes. Absolutely reliable diagnostic features of the taxon are the shape of the leaves of the envelope of the inflorescence, the keeliness of the wrapper leaves and the intermediate leaf segments, to which enough attention has never been paid.

The paper presents the modern data on the role of physical activity in preventive maintenance and treatment of cardiovascular diseases. It is shown that regular physical activity renders an essential positive effect on health and labor productivity. These effects are easily predicted, depend on the loading, and are suitable for many people. We report the data on changes in NO and RO’ levels and in inhibitors of free radicals in cells, as well as on molecular processes in endothelia and muscles (such as a high level of metabolism of phosphates and lowered expression of NAD(P)H oxidazes), depending on the intensity of physical exercises showing a decrease in oxidative stress at moderate physical activity. Recommendations on programming exercises for people suffering from various cardiovascular diseases are presented.

The effect of fluorine-containing compounds (sodium fluoride and fluoroacetic acid) on the activity of acid phosphatase and acid DNAse in an acute toxicological experiment is obtained and the spectrum of soluble liver proteins of the river snail is studied for the first time. The changes in specific activity are revealed by comparing them with those of control snails during the period of exposure (96 hours) with toxicants. The spectra of soluble proteins exhibit the appearance of protein fractions induced by toxic effects, which can be used in biochemical testing of the aquatic environment.

. The effect of fluoxetine on memory processes is studied by using the model of the conditioned reflex of passive avoidance (CRPA) in male Wistar rats with a different phenotype of the nervous system and a different ratio of the activity of monoaminergic (MA) systems of the brain. High rates of saving of CRPA against the background of administration of a psychopharmacological preparation are found in convulsively-tolerant rats, expressed in an increase in the total time of residence of animals in a safe camera compartment, in an increase in a search activity and a low vegetative index, as well as in an increase in the number of rats with the skill kept. Unlike the control group, convulsive-sensitive rats show a decrease in these parameters. It is assumed that the individual animal's sensitivity to the action of psychopharmacological fluoxetine drug and the direction of effects caused by it in the mnemonic processes are due to the different initial ratio of activity of MA-systems of different brain structures.

The paper considers the problem of treating skin burn injuries with the help of a new promising medicinal preparation - zincatran - in combination with IR irradiation. It has been proved that zincatran significantly accelerates the healing of skin burns. At the same time, its effectiveness is higher than that of trekrezan and higher than that of the balsamic liniment (Vishnevsky ointment). The question of the role of methods of IR irradiation and zinc application in a molecule of zincatran, as a stimulant of proliferative processes during thermal skin burns, is discussed.

The paper describes the role of simplest crustaceans in the food of fıshes in the Khojahasan lake of the Absheron peninsula. In the course of the research 57 fish samples belonging to two species [Europian carp (Cyprinus carpio) and golden carp (Carassius auratus gibelio)] from the Khojahasan lake were studied. Eight types of food components [chironomus larvaes (Procladius sp., Stempellina sp., Tanytarsus sp.), oligochaetes (Nais sp., Limnodrilus sp., Tubifex sp.), rotators (Brachionus sp., Keratella sp.), simplest crustaceans (Daphnia sp., Acanthocyclops sp.), other insect larvaes, detrit, plant residues, algae] are found in the gastrointestinal tract of mature individuals of Europian carp, six types of food components [chironomus larvaes (Psectrocladius sp., Tanypus sp.), oligochaetes (Limnodrilus sp., Tubifex sp.), rotators, simplest crustacean, plant residues, algae] are found in the gastrointestinal tract of golden carp in spring and summer. The result of the analysis of the gastrointestinal tract of juveniles of Europian carp show that zooplankton is the main and starting food from beginning of April until end of June.

The paper is devoted to the study of phenology and cycle of seasonal development of 25 species (Opuntia aciculate, O. anahuacensis, O. bentonii, O. camanchica, O. cardiosperma, O. dulcis, O. engelmannii, O. humifusa, O. leucotricha, O. linguiformis, O. lindheimeri, O. littoralis, O. macracantha, O. maxima, O. monacantha, O. phaeacantha, O. polyacantha, O. rastrera, O. rufida, O. stricta, O. sulphurea, O. tardospina, O. tortispina, O. undulate, O. vulgaris) from the genus Opuntia in conditions of covered soils in Absheron. Using the results obtained it is found that all the studied species from the genus Opuntia pass the full cycle of the seasonal development in the covered soil conditions in Absheron (the beginning of the formation of new segments, the phase of budding, the phase of flowering, the formation and ripening of fruits, and the end of vegetation).

We report the results of the study of the macrocomponent composition of 57 samples of natural waters from ten rivers, three ponds and three lakes of urbanized territories of the Moscow region. Using the titrimetric, spectrophotometric, conductometric and potentiometric methods of analysis, the total mineralization, total alkalinity, total hardness, chromaticity, content of nitrate, chloride and phosphate anions and content of the ammonium cation are determined. It is found that the roadside surface waters of the Moscow region do not accumulate nitrate, phosphate and chloride ions and ammonium ions in concentrations exceeding the sanitary-hygienic standards. The ubiquitous excess of chromaticity of the water samples studied is revealed, which is due to the accumulation of organic compounds washed out from soils and bottom sediments.

In accordance with the Federal law requirements, the Moscow region Government adopted a territorial scheme of waste management and identified the need to construct objects of neutralization, processing and disposal of production and consumption waste, taking into account all necessary requirements, including sanitary norms and rules. Priority is given to modernization of existing landfills. Since the creation of any new object of waste management results in considerable social tensions, much time has to be given to explanatory work among the population. Thermal disposal of municipal solid waste at high temperature provides a better environmental impact than the waste disposal in landfills. Main advantages of plants for thermal destruction are described. The regional program and the territorial scheme of the Moscow region provides a set of key measures aimed at reducing the volumes of landfilled waste and involving them in repeated economic circulation as secondary raw materials.

Vietnam is a country of mountains and plateaus, where plains occupy only a quarter of the territory but play a crucial role in the life of the country: most of the population, main cities, industrial enterprises and agricultural lands where rice is grown are concentrated here. Tien Hai is a coastal district of the country involved in the agricultural sector. In addition, the development of Vietnam towards industrialization raises concerns about the quantitative and qualitative composition of agricultural lands. In the Ba Ria city of the Ba Ria - Vung Tau province, the building industry is being intensively developed. Because of the industry development, the types of permitted use of land plots and the composition of the land change dramatically due to their transformation. Thus, the monitoring of the transformation of the land in Vietnam plays a key role in the management of the country's land resources.

Theoretical general problems of interference of a transport complex and ecological situation at a regional level are considered. The paper examines the ratio of the transport infrastructure to natural and recreational landscapes on the territories of ten cities of the Moscow region. The ten cities in question are divided into three groups. Groups of the factors of the transport complex influencing the natural and ecological environment in the cities both in general, and in separate groups of the cities of the Moscow region are allocated. Measures for improvement of the ecological situation in the cities of the Moscow region in connection with regulation of work of the transport complex are proposed.

We consider the peculiarities of the process of sulfate reduction in three freshwater lakes with different anthropogenic impacts and groundwater types. Quantitative indicators of this process are presented. The results obtained are compared and the features of sulfate reduction in each of the reservoirs are highlighted. It is shown that the intensive sulfate reduction in water in summer is recorded for the most anthropogenically loaded lake. For a reservoir with the receipt of a sulfate type of groundwater, the process proceeds with the greatest accumulation of reduced sulfur compounds both in water and in bottom sediments.
