Abstract: ABSTRACT: Cow urine therapy and all traditional practices from Indian systems of medicine have a strong scientific base. The cow has proved to be a boon in the areas of agriculture, science and technology, industry, energy, medicine etc for the development of any nation, in addition being eco-friendly in nature. In the present study the antibacterial potentials of cow urine were investigated. Total 14 pathogenic and non-pathogenic bacterial cultures were used as test organism against 10 different cow urine samples. The highest zone of inhibition was shown by sample G against P aeruginosa NCIM 2945 (1.8cm) while the smallest zone of inhibition was shown against E. coli NCIM 2065(0.3 cm) by sample A. Based on cumulative effect against the test organism, the urine sample G was found to be the most efficient inhibiting all the 14 test cultures. The antibacterial activity reported by sample G was comparable with standard antibiotics. A higher zone of inhibition was observed by sample G against P aeruginosa NCIM 2945 as compared to that of Gentamicin, Oxacillin and vancomycin. Though the urine sample G showed a strong antibacterial activity against all the test organisms, but the activity was reported low against the entire Gram positive bacteria compared to Gram negative bacteria. The presence of proline which is considered as a major amino acid in antimicrobial peptides was also observed in the urine sample G.
Air filtering through the building envelope
Petrosova D.V.
Magazine of Civil Engineering , 2012,
Abstract: Recently, building envelopes with efficient insulation of low thermal conductivity, including light building envelope, which allow to increase thermal protection of buildings, are widely used. This new building envelope require a comprehensive study, because previously considered unimportant features often start to make significant effect on the performance characteristics of structures.To reduce the air permeability in the constructions wind-proof membranes are used. However, the influence of air filtering in such structures has not been researched yet.When the air-permeable building envelopes are used, the heat flow is moved away also due to the air filtering. It is proposed to take into account the convective heat transfer mechanism commensurate with the conductive heat transfer mechanism. In the formula for determining the heat flow due to the air filtering the filtration coefficient of air through the building envelope is used. This coefficient is found experimentally for light building envelopes.Furthermore, the empirical expression for the filtration coefficient, which relates it and the coefficient of heat loss is found.
Quantitative assessment of the conservative addition transfer by filtration flow through the wall

Magazine of Civil Engineering , 2012,
Abstract: Effect of air filtration on the temperature and humidity conditions of building structures is significant. This explains the great attention which is paid to the question of air filtering through the building envelope. In the air permeable building envelopes heat flow is carried out including by air filtration. Filtering transfer of conservative addition is comparable with heat transfer by thermal conduction. A method for calculating the heat flow by filtering heat transfer was proposed. Calculation examples for lightweight building envelope were given.
Integrated characteristics of thermogravitational convection in the air layer of ventilated facades
D.V. Nemova
Magazine of Civil Engineering , 2013,
Abstract: Ventilated facades solve at least two topical problems for civil engineering: it allows reducing the humidity (concentration of water vapor) on warmed wall surface and reducing heat losses from facade to the environment. The major factor in solving these problems is the air stream, washing the facade wall in the vertical direction. For the free-convective flow the width of the channel, providing the maximum consumption of the air is called optimum width of the ventilated channel. The free-convective flow in a vertical slot gap of facade ventilated space will be stylized by a barotropic flow with an indicator of a polytrope of n, n < k proportional to intensity of a heat transfer between hot wall and air. The motivation of a choice of the sizes of the vertical ventilated channel of ventilated facades in the conditions of the free-convective flow is given in the present article and it is based on using results of numerical experiments run on real ventilated designs.
Ventilated facades: review of main problems
D.V. Nemova
Magazine of Civil Engineering , 2010,
Abstract: The design of ventilated facades becomes more and more popular.Ventilated facades are installed on erected and reconstructed public, office and residential buildings.In this article the basic problems relating to the ventilated facade system are considered. The design, installation process, thermotechnical properties, fire safety, economic efficiency are considered. The purpose of the article is the prevention in practice the most often errors which arise in time of installation, operation and dismantle of such systems.After the analysis following basic problems of systems with ventilated facades have been allocated:calculation of necessary air gap;selection of qualitative materials and installation;fire safety;maintenance of required hermal resistance.Application of ventilated facades systems for warming of buildings and increasing of their power efficiency demands the thought over and complex approach. Such systems are not so economic, energy effective and durable as it is considered to be.

Marketing ì Mened?ment Innovacìj , 2011,
Abstract: Improved categories of the theory of development, namely: the definition of marketing, the distinction which is focusing on: the relationship between actors, the effectiveness of life of the enterprise, information and interaction based on solving the existing conflicts that arise in of interaction with the most influential actors of the internal environment, such as partners and consumers; classification differences in terms of their impact on marketing activities for more theoretically grounded and practically important characteristics: type of environment (external, internal conflicts), the level of complexity, the possibility of solution 'Liabilities, priority resolution; classification of factors influencing the development of the new classification attributes: of nature, essence or kontekstnist transformations patency (display) process.
