  Keywords: Environmental Flow Assessment; Water resource management; Environmental flow; Ecological management condition; Ecosystem water.

  Abstract
  This study has used a general-purpose multi-objective programming model to determine the minimum human-ecological water balance and ecosystems to determine at least jericanological or minimal blue-water levels. As the two target functions are, respectively, the blue index for humans and the ecosystem index. A case study on the Sufi Chai River. To determine the environmental water requirement of the Sufi River tea, it has been wetted with a hydrostatic method and hydrologic methods of flow transmission curve continuity and tonnage have been used. In the hydraulic method, the soaked environment was used to determine the breaking point from 4 practices: curve slope, maximum curvature, ideal point with scale factor 1 and ideal point with scale factor 2. The results indicate that the Tenant method has shortcomings in estimating the environmental water requirement. Based on the results, the values obtained from the flow transmission curve method are preferable to ecological management conditions than other methods.

  Keywords: Innovative development of agricultural industry, internal costs of scientific research, grant support of scientific research, high qualified personnel; agrifood policy.

  Abstract
  This study presents problems impeding the development and implementation of Russian innovations in agricultural production. The main problem is the financing of innovation, due to a low proportion of public resources used in the creation and implementation of innovations. In comparison with the developed countries, the amount of state financing for innovations in Russia should be increased by ten times. In addition, working funds to support scientists in a global sense do not solve the problem of new scientific knowledge financing, not to mention the implementation into the real sector of the economy. A small share of public investment in innovation does not contribute to the solution of the problem of advanced innovative development. In addition, the public-private partnership helps to attract innovation in the real sector of the economy in all developed countries but does not work in Russia as it. lacks state regulatory functions for this. This study identifies factors and trends that do not contribute to the effective and advanced development of the economy in terms of its innovative development. The need to increase domestic spending on research in agriculture by 5-7 times is substantiated. Negative trends in the reproduction of scientific personnel are revealed. This is the lack of financial motivation to work in the scientific field, inefficient system of postgraduate and doctoral studies. It is proved that the impact of grant support on the level of research funding, which is not more than 6.2% in domestic research costs, is insolvent. To alleviate the problem of innovative activity of economic entities, it is necessary to develop a targeted agricultural innovation policy that determines the goals, objectives, and mechanisms for its implementation, taking into account the priorities defined by the Russian Federation, as well as foreign experiences.

  Keywords: Ferrocement beam; static four-point bending test; shear connectors; load-mid span deflection relationships; flexural load carrying capacity.

  Abstract
  The flexural behaviors of reinforced concrete beams strengthened by ferrocement are studied in this work. Three beam specimens with identical size and steel reinforcement are made to perform the experiments. The first beam is used as a reference while the second and the third beams are strengthened by ferrocement, composed of external steel reinforcing bars, wire mesh, and mortar cement. The surface of strengthening specimens is intentionally rough before wrapping by steel wire mesh and patched by mortar cement for the second beam, but for the third beam, shear connectors are provided between the concrete surface and ferrocement. All specimens are tested under static four-point bending test. The results show that significantly increased flexural strengths of strengthening specimens, the second and the third beams, over the reference specimen, are found, but ductility of the specimen with shear connectors is significantly larger than the others.

  Keywords: High-tech investment; International sanctions; protectionism; Mechanisms of import substitution; Strategy of import substitution; Domestic technology development.

  Abstract
  The relevance problem of import substitution is explained with the practicability of using a systematic approach to analyze the real state of the Russian economy. This article provides a brief historical background on the origin of the idea of import substitution in the XVIII century and its further development. It considers its essence as a response to international sanctions imposed by the USA, the EU, and their allies. Noting that import substitution should be distinguished from protectionism, which is based on different aims. The mechanisms of import substitution by three main categories are indicated. There is a list of rules that must be followed when developing strategies for import substitution. The article highlights the negative effect of the sanction imposition, reflected on the Russian foreign trade in 2016–2017, compared to 2013, as well as on the supply of high-tech investment products. Also, it gives particular examples of the current situation in some spheres of economic activity and identifies threshold requirements in industrial production in the world practice and Russia. Focusing on the effective re-equipment of the Russian economy, it is necessary to manufacture competitive labour tools in a certain order: from the production of labour tools for the machine-tool industry to their production for the engineering industries and to the production for other sectors of the economy. Attention should be paid to the quality of the workforce capable of servicing advanced technologies and equipment. There are tasks whose introduction will contribute to a successful solution of the problem of import substitution. The aim of this article is to identify "bottlenecks" in the development of the Russian economy and suggest measures to eliminate them, focusing on its essential components. Particular measures to increase the real potential of the country are suggested.

  Abstract
  Today, the architecture of Iranian houses faces a historic break from its own identity background, and all attempts to produce Iranian architecture have been reduced to formal imitations. This paper examines the mathematical-graphical model for analyzing the spatial configuration of traditional houses in the moderate and humid climate of Iran to response this question which how a model for the design of today's houses in northern Iran can be extracted from past monuments of this land. In this research, six of the historic houses in the north of the country were randomly selected, all of which are similar in size and belong to a 100-year time interval. In these cases, after the preparing convex map, their justified plan graph (JPG) is plotted and readout. In fact, in each house, architectural plan, convex map, JPG, and mathematical calculations for control value, integration value and other space parameters are done and their charts are mapped and the data of each of the six houses are compared. By comparing the justified plan graph of the houses as well as the comparison of control value and integration value, the spaces each house has a similar pattern in all of them that is close to each other in terms of mean depth, control value, and integration value of the spaces. In all cases, the courtyard has the most integration value, and the closet, the storage, and the terrace have the least integration value and control value. Finally, by analyzing the JPG, the computational data is the same pattern in all the cases that can be considered as the archetype of traditional houses in northern Iran. An ancient pattern that can be used in the identity spatial organization of today's generations of houses in northern Iran.

  Abstract
  This research investigates the Shuttle Radar Topography Mission (SRTM) Version 3 Global 30m produced by The National Aeronautics and Space Administration (NASA). As one of the free download data sources from the internet, it is widely used for topographic mapping with global scale of accuracy from North America and Europe test sites. However, there is lack of local accuracy assessment and verification for SRTM data as in Southeast Asia and Thailand due to the absence of Global Positioning System (GPS) benchmarks used as sources of Ground Control Points (GCP). This research used GNSS L-band global correction service ATLAS? (Hemisphere) for building the GPS trajectory as a source of GCP for assessment and improving accuracy of SRTM Version 3 data. The result shows that absolute vertical accuracy was achieved less than Vertical RMS 1.3 meters in comparing with relative vertical RMS 8.7 meters in Euro-Asia continent accuracy scale as announced in SRTM data specification. These results and method can be useful for engineers who apply DEMs for various applications such as updating topographic map for landscape design and rural - urban development project in Thailand.

  Abstract
  This research investigated the consequences of using virtual social networks in promoting the social capital. The research method was qualitative, type of phenomenology, and the field of research included managers and experts in the field of media and communications, as well as the professors and social science experts. A purposive sampling method was used and the data were extracted using semi-structured interviews and analyzed by Colaizzi seven-step method. The results were collected until the theoretical saturation of the information. Findings indicated that the most important factors of social capital enhancement included the easy interaction and communication in cyberspace, increasing the coherence and participation by virtual social networks, social bonding in virtual social networks, interactive communication between people and government, and the power of virtual social networking. On the other hand, the most important barriers to social capital promotion included the gradual change in the norms and positive beliefs in cyberspace, social isolation, the publication of negative news in cyberspace, the expansion of individualism in cyberspace, weakening of the traditional social communication network, the promotion of disconfidence in social relations and weakening of ethics. The findings also indicated that the virtual social networks have both positive and negative outcomes. The social capital can be promoted with the correct use of social capital strengthening factors and removing the barriers of social capital.

  Keywords: Corporation size; Corporation age; Profitability; D/E ratio; Growth opportunity; Liquidity.

  Abstract
  Capital Structure of a corporation will indicate the relationship between financial leverage and equity of shareowners. Financial leverage will make limitations for managers while capital increases flexibility and making decision ability. Mainly, using financial leverage in financial structure will cause investors' expected returns increase but this function can corporation risk, too. So, using financial leverage is like a double-edged sword (mutual relationship) that can increase or decrease corporation value. This research aims to investigate the effective factors on debt to equity(D/E) ratio of shareowners in the capital structure of the accepted corporations in Tehran Stock Exchange. This research is comparatively based on its performance logic and research time is sectional and its performance method is descriptive-measuring and post-eventual. Research statistic population includesall the accepted corporations in Tehran Stock Exchange witha sample of 142 corporations chosen by systematic deletion. Research finding indicates that corporation growth opportunity, profitability, corporation size,and corporation age have positive meaningful effects on D/E ratio of shareowners. However, obvious properties, liquidity,andtangible assethave negative meaningful effects on D/Eratio of shareowners. It is suggested that research studied corporations will decrease D/E ratio of shareowners by an increase of usual stock sale.

  Keywords: Manual method; Numerical value; Proportionality factor; Invariance principle; Electrical formula; Conceptual model; Normal steady-state mode of power lines; Mathematical static model.

  Abstract
  The purpose of the paper is to develop a new calculation method. The subject area of the study is the calculation of the steady-state mode of a three-phase high-voltage overhead power line. The basis of the method is simple mathematical models that make it possible, in the presence of three initial data with a high degree of reliability, to manually calculate many electrical parameters, and to verify electrical calculations, including those made using computer programs. The key component of the models is the proportionality factor, which takes a different numerical value for each of them. The hypothesis for the development of the method was the application of the invariance principle to the basic laws and known relations of electrical engineering. The method is simple, operative and successfully verified. The hypothesis is proven. The calculation error when applying the method is less than 2%. Software systems are not required for the implementation of the method. According to the results of the study, conclusions were made and practical recommendations were given. The prospects for further research were presented. The method can be used by experts, engineers, and students of electrical power and electrical engineering programs of higher education institutions.
