Two kinds of solar thermal power generation systems (trough and tower) are selected as the research objects. The life cycle assessment (LCA) method is used to make a systematic and comprehensive environmental impact assessment on the trough and tower solar thermal power generation. This paper mainly analyzes the three stages of materials, production and transportation of two kinds of solar thermal power generation, calculates the unit energy consumption and environmental impact of the three stages respectively, and compares the analysis results of the two systems. At the same time, Rankine cycle is used to compare the thermal efficiency of the two systems.

This paper reviews and comments on the evaluation methods of the recreational value of natural landscape resources, pointing out that the current popular TCM method and CVM method both rely too much on the market prediction conclusion and cannot truly reflect the recreational value, and putting forward the idea, specific operation steps and calculation methods of evaluating the recreational value of natural landscape resources with tourism environmental capacity.

Sustainable leadership matters, spreads and lasts. It is shared responsibility, that does not unduly deplete human or financial resources, and that cares for avoids exerting negative damage on the surrounding educational and community environment. In fact, sustainability does not simply mean whether something can last. It addresses how particular initiatives can be developed without compromising the development of others in the surrounding environment, now and in the future. Sustainable leadership is one of the most valued characteristics that employers and stakeholders are looking for, especially in this new fast changing market. Having a good Leadership sense is essential for the success of a company and for its collaborative working environment. Leadership is usually linked with sustained learning, success, diversity, capacity and maintaining a continuous development of other team members and coworkers. However, various authors are debating and discussing how we define good and sustainable leadership and what we expect from a leader to do, but few of them are raising the question how we can build and create leaders?. We present in this paper an overview of leadership definition and the challenges set by this important and complex concept. We propose a vision based on four pillars to create an adequate environment to build leaders. We present and describe our perspective on what we need to provide and establish as a company or a community in order to create an effective team of leaders in the perspective of the new requirements of the market and the expectations of companies.

Nanotransformations of a blanket at the fair dimensional combined processing with imposing of electric field the tool in the form of untied metal granules are considered. An object of researches are the figurine details applied in aviation, the missile and space equipment and in the oil and gas industry: driving wheels and a flowing part of cases of turbo-pump units, screws, krylchatka where there are sites of variable curvature with limited access of the tool in a processing zone.It is shown that the combination in the combined process of two-component technological environments of current carrying granules and the electroconductive liquid environment given with a high speed to a processing zone allows to receive the required quality of a blanket; action of electric field from a source with the increased tension allows to create at fair dimensional processingthe required peening from blows of firm granules. It gives the chance to raise a resource and durability of responsible knots of the aerospace equipment and oil and gas equipment, to expand the field of use of the combined processing with untied granules on a detailwith the sitesnot available to processing by a profile electrode.
