Features of the study creep and floodplain defluxion in the Raifa region Of The Greater Volga-Kama Biosphere Reserve (GVKBR) "UNESCO"
The phenomenon of a slow displacement of unconsolidated soil that is widely known by the term "creep" (from English creep - crawl) and "defluxion" (from German defluktion - drip, leak) covers almost all slopes of dry land. In order to identify the geomorphological role of this phenomenon stationary studies of creep and floodplain defluxion of small rivers in valleys of the Middle Volga are widely held. In general, the cause of the displacement is a permanent force of gravity, slopes, soil conditions and other factors. Creep and defluxion appear due to soil volume changes which occur as a result of temperature compression and expansion, freezing and thawing, swelling and shrinkage of soil, and development and dying off of the root system of plants. The relief of the investigated area (on the example of Raifa region of the Greater Volga-Kama Biosphere Reserve (GVKBR) "UNESCO") was created as a result of a long interaction between processes of internal and external dynamics
The latitude-zonal variability of hydrophysical and energy parameters of soils of the East and the South of European Part of Russia
The soil cover of the east and the south of the European territory of Russia has been explored good enough and in various aspects. However, hydrophysical soil parameters are not well studied, despite the fact that they largely determine the crop yields of the cultivated plants. To this purpose, in 2010 during a field expedition by the route: Kazan-Cheboksary-Saratov-Volgograd-Elista-Caucasian Mineral water- Krasnodar-Rostov-on the Don-Voronezh- Tambov-Penza- Saransk-Kazan in July and August hydrophysical the parameters of the basic zonal soils of European Russia were estimated. Hydrophysical and soil-energy parameters of zonal soils were determined, the curves of the main hydrophysical characteristics of the studied soils to be the basis of water-reclamation and irrigation activities in the black earth, chestnut soil and gray-brown half-desert soils were calculated. The complex of hydro-studied and soil and energy parameters of soils east and the south of European Russia is an important step in understanding the links between the territory of the hydro-climatic conditions and the nature of the vegetation which grows in the area
Phyto-geographical approach in creation urban landscapes (by the example of Kazan City)
A great emphasis in the urbanized landscapes is laid on the reconstruction of the existing natural vegetation and the formation of artificial greenery. Green construction projects must take into account data on the biological characteristics of tree species and their adaptation to the specific growing conditions, as well as understand the peculiarity of the geographical conditions and abiotic environmental factors emerging in urban environment. We have identified 99 species and forms on the territory of the residential areas of Kazan, as well as held biomorphological analysis of the morphostructural and ecological features of dendroflora. Based on data on landscape features within the urban areas we have distinguished 10 types of plants subject to their anthropogenic transformation. For each of them, we have conducted assessment of their habitat conditions by indication methods, as well as proposed groups of species of trees and shrubs able to form sustainable plant communities
Experience of field geomorphological research study on the territory of the Volzhsko-Kamsky natural reserve
© MCSER-Mediterranean Center of Social and Educational Research. Since the 1940s on the territory of the Raifsky site of Bolshoy Volzhsko-Kamsky biospherical reserve (BVKBR) "UNESCO" the geomorphological conditions are subject to very detailed study. The study of modern geomorphological phenomena and processes on the territory of the Raifsky reserve was the main purpose of the work and geomorphological studies. Formation of the relief the territory under study is closely connected with the history of development of the valley of the Volga River. The territory of the reserve is very heterogeneous by morphology, genesis and history of the development of land forms. It is important to identify the interaction of the relief with the processes of territory development and settlement, i.e. geomorphological conditions are the pledge of successful development of the region
Territorial reserves of major cities: Challenges,experience,solutions
© 2016,International Journal of Pharmacy and Technology. All rights reserved.Currently,the problem of territorial reserves is quite relevant for dynamically developing urban systems,since a large city feels an increasing need for the new development resources such as areas,infrastructure,water sources,etc.,but many of them turn out to be exhausted or close to exhaustion within the urban area. This paper deals with the approaches to the problem of deficit in areas within the city limits based on the analysis and generalization of the world and Russian experience in the urban planning policy. Practice has shown that the territorial problems in cities may be solved by increasing the area of the city,urban densification,demolition of buildings and structures,by transferring industrial enterprises outside the city margin,high-rise construction,by creating filled (reclamation) areas,and underground construction. The paper deals with the features,advantages and disadvantages of the considered approaches to the designated problem of land shortage within the urban area. Considerable attention has been paid to environmental issues arising out of the implementation of any variant of solving the territorial problems of the city. The study found that the decision of the territorial deficit in the process of urban development has a complex nature. To achieve the best effect,it would be appropriate to use the combinations of various approaches,covered in this paper,in the urban planning practice
CONSERVATIVE FLUIDS AND LUBRICANTS BASED ON TURBINE OIL, NITRO, AMIDO AND PARAFFIN WAX
To create conservation fluids and lubricants based on the oil acids and polyethylene polyamine (PEPA) synthesized amidoamines, and based on α-olefins (C12, C14 and C16-C18) and the nitric acids-nitro compounds. Using of amido, nitro and solid n-paraffins in the turbine oil T-30 (Standard 32-74) formulated lubricants and conservation fluid which are tested under different conditions. It is shown that in comparison with the preservative fluid, the preservative lubrication more effective
Male health and obesity – diagnostic and therapeutic approach
Obesity may present as a significant medical problem for any person, regardless of age or gender. In men obesity causes considerable psychological stress, sexual dysfunction, subfertility, hypogonadism and cardiovascular conditions. These problems may form numerous pathological associations between each other, creating a vicious circle. The main factors which influence male fertility and sexual function in obesity and metabolic syndrome are imbalance of sex hormones and systemic inflammation. In many patients symptomatic treatment is necessary for above-mentioned manifestations, but it is always rational to act on their pathophysiology and to recommend to lower the body mass by diet and lifestyle modification. When it proves impossible for the patient to follow such recommendations and when behavioral approach fails, central-acting and peripheral-acting medications may be used, including orlistat, sibutramine and liraglutide. Bariatric surgery should be offered to patients with high body mass index in whom conservative management fails. Without elimination of excess body mass it is difficult to solve problems regarding sexual dysfunction, hypogonadism and subfertility in obese males. All these issues and available modes of pharmacological treatment are described in this review
The Formation of Civic Identity on the Example of the Project of Festivals of Friendship of Peoples “Dialogue of Cultures"
В статье рассмотрен вопрос проведения социально-культурной деятельности некоммерческой организации как путь к межкультурному диалогу и гармонии.The article consider s the issue of conducting socio-cultural activities of a non-profit organization as a way to intercultural dialogue and harmony
Elliptical motions of stars in close binary systems
Motions of stars in close binary systems with a conservative mass exchange
are examined. It is shown that Paczynski-Huang model widely used now for
obtaining the semi-major axis variation of a relative stars orbit is incorrect,
because it brings about large mistakes. A new model suitable for elliptical
orbits of stars is proposed. Both of reactive and attractive forces between
stars and a substance of the flowing jet are taken into account. A possibility
of a mass exchange at presence of accretion disk is considere
