Abstract: This paper is devoted to the history of exploration of sintezed and natural gas hydrate. Academic, engineering and energy periods of the history of gas hydrates studies are described. The most significant researches in this area are described. The main practical projects in the world for the study and production of gas hydrates are reviewed.

Abstract: Fishermen poverty is multi-dimensional problems. Since the fishermen income always under regional minimum wage. Inversely with position of Indonesia that become the world third largest in fishing production. At the same time, Indonesian fisheries are under threat due to degradation of marine ecosystem and overfishing. Therefore, enhancing the massive production is not a solution to solve all problems. The main purpose of this paper is collecting the view of researchers related to the causes and solutions as poverty alleviation. The poverty alleviations can be started with improvement in fish catching and processing, transparent and environmental friendly, increasing fishermen’s ability, and good management of assets.

Abstract: This article addresses contemporary construction polymer elements found useful in civil engineering and construction in Russia due to their high technical and economical efficiency. Advantages and drawbacks of the polymer materials are reviewed. This work in no way claims a fullness of reviewing all the issues of using polymers in construction, but it nevertheless enables to provide a general insight into the problems to be solved in the field of future production and use of environmentally safe polymer materials for construction applications. One of the substantial goals of the applied research is to design rather durable, non-toxic and fire-resistant construction materials intended for construction of residential and public buildings. Readers can get an overview about ecological problems linked to the production and application of the polymers in construction field.

Abstract: The article considers contemporary methods and especially recycling of wood waste. The volume of wood waste is constantly growing due to the increase in the number of buildings subject to demolition or dismantling, reconstruction and repair works. The article contains the main requirements to the raw material derived from waste. Advantages of products made from wood-polymer composite materials on physic mechanical parameters. The comparative characteristic of cost for the production of wood-polymer plastic. It is noted that production made from wood polymer composite materials has unlimited product range, including boards, various profiled molded and moulded details with complicated shape (the board for the floor, skirting board, baguette, etc).

Abstract: The concept of sustainable building incorporates and integrates a variety of strategies during the design, construction and operation of building projects. The use of green building materials and products represents one important strategy in the design of a building. Green building materials offer specific benefits to the building owner and building occupants such as reducing maintenance/replacement costs over the life of the building, energy conservation, improving occupant health and productivity, and greater design flexibility. Thus, the aim of this paper is to identify the similarities and the differences for the selected green assessment tools which can be obtained stage by stage of the RIBA Outline Plan of Work 2013. The study had been carried out through a comparative analysis. The finding is predicted to help the construction industry practitioners to be able to understand the assessment criteria involved at every stages in the construction process concerning on material and recourses. Especially for those who are concerned on green building and to sustain our natural environment.

Abstract: In large-scale urban adaptation and real estate development process, some protective cultural relic buildings and modern excellent architecture face the reality of being demolished, that will produce a large number of construction rubbish, pollute the environment , at the same time, cause a large number of resources waste. In this paper, the application of monolithic moving technique of building is introduced, which can not only save nature resources, but also maximum reduce pollution to the environment.

Abstract: In this study, the Auxiliary Power Unit (APU) and the Ground Power Unit (GPU) that are required meet the energy demand in ground operations of aircraft were compared in terms of their damages –human health (disability adjusted life years- DALYs), ecosystem quality (PDF.m².yr) and resources (MJ Surplus). These damages were calculated with gate-to-gate method of Life Cycle Assessment (LCA). This assessment was held on three main stages; capital investment, operation and maintenance. SimaPro 7.2.4 was used for this calculation. Human Health Damages (HHDs) of APU were found to be (0.0557 -disability adjusted life years- DALYs) 20.34 days/year while HHDs of GPU were calculated as (0.0411 -disability adjusted life years-DALYs) 15 days/year. While Ecosystem Quality Damages (EQDs) of APU were calculated as 103366.37 PDF.m².yr, EQDs of GPU were found to be 82651.23 PDF.m².yr. In other words, although the use of APU gives rise to loss of 0.1 species –1 year, 1 square kilometer area, the use of GPU gives rise to loss of 0.083 species. With regards to Resources Damages (RDs), 62125 MJ surplus energy needed for future extractions of minerals and fossil fuel considering APU, one the other hand 36002 MJ surplus energy needed for future considering GPU. As a result, the use of APU effects on human health, ecosystem quality and resources was determined greater than the use of GPU for 30 minute. The use of GPU has less impact on human health, ecosystem quality and resources in ground operations.

Abstract: With the morphological characters, anatomy and molecular biology research, 29 entomopathogenic nematodes populations isolated from Gansu province were identified and the resoult showed that they were 8 species of EPN, Steinernema feltiae,Steinernema bicornutum,Steinernema affin,Steinernema krusse and Steinernema karil were belong to Steinernema while Heterorhabditis brevicaudis,Heterorhabditis megidi and Heterorhabditis marelatu were belong to Heterorhabditis respectively. And what more research found that S. affin,S. krusse,S. karil and H. marelatu were new species in China.

Abstract: Based on the endogenous economic growth model, this paper presented a growth model with the pollution control and then obtained the optimal economic growth path solutions.

Abstract: This paper focuses on the application of cloud manufacturing technology in the development of digital intelligent production control platform. Combined with the characteristics of NC machine shop, using the cloud manufacturing technology, the intelligent scheduling of production plan based on the theory of constraints, and multi-objective scheduling optimization technology, developed the target task balance optimization, manufacturing resource planning, equipment load balance module etc., achieved tracking and monitoring of the status of schedule, completion, production etc., ensure the statistics and analysis of production data correct and complete, and provide the basis for evaluation of production condition.
