Ensuring stability of economic development, an energy and ecological safety is connected with increase in energy efficiency and decrease in power consumption of economy. The main indicator of resource intensity is power consumption. power consumption characterizes amounts of an energy consumption and fuel on the basic and auxiliary engineering procedures of production of products, performance of works, rendering services based on the set technological system. The Russian economy is one of the most power-intensive ...

In our century and especially in recent decades the noise level reached an increasing width, becoming a polluting source of the same severity as chemical pollution. Increasing power and work speed of equipments has contributed to diversifying and increasing the number of noise sources and thus increased number of people exposed. Noise generating sources in technological procedures of processing may be of continuous nature (pneumatic energy production, water transport) or intermittent (systems for transporting mine...

Animal bodies (mammalian and human body) show a great capacity for adaptation, both to the fluctuations of environmental factors and also regarding the nutrition, increasingly modified. General Adaptation Syndrome (GAS) of organisms, began to be studied in animals and also in humans. In human bodyes, GAS is studied because a number of disease with great significance psychologically, physiological but especially medical, appeard. In both categories of bodies, GAS is investigated by the presence of markers that high...

Even though land cover and use changes, climate changes and altered use of energy, known together as the пїЅglobal changesпїЅ have been studied intensively, their relationships are still under debate, especially with respect of assessing the anthropogenic contribution. The study relies on the hypothesis according to which poverty and lack of environmental awareness could lead to disastrous environmental impacts, with adverse economic consequences. Starting from an assessment of deforestations based on GREENPEACE d...

The appearance of species imported in the EU, and so on the Romanian market, led to a change in consumer preference towards new species of fish (tilapia, African catfish, pangasius) and aquaculture products (shrimp, clams, oyster, etc.). One of these species is tilapia (Oreochromis niloticus) which, at European level, the import volume is about 10,000 tons / year. In order to reduce imports and increase the competitiveness of aquaculture in the EU have been taken strategic measures to develop technologies that int...

The use of synthesis chemical substances in agriculture for increasing agricultural production and ensuring food across the globe is a process that has as a reverse negative effects on the environment and human health.

Wheat resistance to heavy metals (HM) is an urgent ecological problem and it can limit crop production around the many countries in the world. HM is considered as an environmental factor of the anthropogenous nature which influences growth and development of wheat. New approaches are focusing on using of a genetic pool of wild-growing types of crops as an introgressive genetic material for increasing wheat adaptability to HM. In the model, laboratory tests of HM influence on wheat growth used the grain yield of 20...

Geophysical data interpretation methods are very important for the study of the EarthпїЅs internal structure and gas and oil exploration. In this paper we offer a method to interpret gravity anomalies (identification of the local density of inhomogeneities) based on new grid algorithms: a three dimensional density distribution is constructed as grid functions by identified anomalies from the sources split along horizontal layers. Algorithm is based on new grid techniques of 3D gravity inversion. The initial approx...

A hydraulic fracturing job was performed to stimulate gas flow from a horizontal wellbore located in Poland. The whole operation was overseen by means of microseismic monitoring. For this purpose, an array of 12000 geophones was deployed on ground in form of patches distributed unevenly in a region of 4km from the wellbore. The array was constantly recording seismic signals during whole fracturing processed. Such recorded signals can by analyzed to locate, both in time and space, events connected to cracking rocks...

The skin is covered with a hydrolipid film that, depending on the area of the body, comprises secretions from sebaceous glands and from apocrine and eccrine sweat glands. Decomposition products from corneocytes and cornification (cellular debris and stratum corneum lipids) in the process of being shed are also present. This film provides a natural defense against pathogenic organisms but also attracts dirt and pollutants from the environment. Thus, periodic cleansing to remove debris, dirt, and odor is essential t...

The current hard-to-recover oil reserves in Russia stand for more than 60% of total recoverable oil resources. These kind of reservoirs with acceptable technical and economic indicators are extracted only by applying physicochemical recovery techniques. Thus, an important relevance is given to selection of most effective EOR technology, which is directed to decrease the residual oil saturation in rock formations. Various chemical reagents including composites based on water-soluble polymers are injected both in Ru...
