The cost of centralized photovoltaic (CPV) power generation has been decreasing rapidly in China. However, the achievement of grid parity is full of uncertainties due to changes in policies and the industry environment. In order to explore the time, price, and external conditions in which grid parity can be achieved, we create the improved grey GM (1, 1) model to estimate the installed capacity over the next 10 years, and apply a learning curve to predict the cost of CPV generation. In the analysis of grid parity, we compare the benchmark price of coal power and the price under the market-oriented mechanism with CPV. The results show that China’s CPV industry will enter the early stage of maturity from 2020 onwards; with the help of benchmark investment, the grid parity of CPV may be achieved in 2022 at the earliest and 2025 at the latest. After 2025, the photovoltaic electricity price will be generally lower than the coal electricity price under marketization. By 2030, CPV power generation costs will reach US $0.05/kWh, the accumulative installed capacity will exceed 370 GW, and the uncertainties will lead to a cumulative installed gap of nearly 100 GW.

Abstract The determination and separation of enantiomers is an interesting and important topic of research in various fields, e.g., biochemistry, food science, pharmaceutical industry, environment, etc. Although these compounds possess identical physicochemical properties, a pair of enantiomers often has different pharmacological, toxicological, and metabolic activities. For this reason, chiral discrimination by using chromatographic and electromigration techniques has become an urgent need in the pharmaceutical field. This review intends to offer the “state of the art” about the separation of chiral antifungal drugs and several related precursors by both liquid and gas chromatography, as well as electromigration methods. This overview is organized into two sections. The first one describes general considerations on chiral antifungal drugs. The second part deals with the main analytical methods for the enantiomeric discrimination of these drugs, including a brief description of chiral selectors and stationary phases. Moreover, many recent applications attesting the great interest of analytical chemists in the field of enantiomeric separation are presented.

The university does not have competency to produce product which can absorbed by industry environment (Zulganef and Munabi, 2009), while the most wanted occupation by educated employee is as worker that give monthly compensation and very little (5%) that choose occupation or job as a entrepreneur after graduated from the university. The definition as entrepreneur as the man who has idea and man of action often related as the innovative or creative man factors than assumed could increase the entrepreneur, attitude, and personality (Me Cleland and David, 1987) and adversity intelligence (Stoltz, 2000) and the performance entrepreneurship study (Djamarah, 1994). The aims of the research: a) to analyze the performance of entrepreneurship study, adversity intelligence and attitude, with the intend of entrepreneur from the students; b) to examine and analyze the influence of performance of entrepreneurship study, adversity intelligence and the student attitude for entrepreneur aim. This research use multi regression analysis with 93 student respondent. The research shows that: a) The reaction of students to adversity intelligence, study report, attitude and intention of entrepreneur is high; b) There are simultan influence from adversity intelligence, the attitude of student to the intend of entrepreneur just show for the attitude, while for adversity intelligence and report study did not show its influence significantly.

The purpose of the article is to describe methodological approaches to the complex concept of reliability of engineering enterprises in a competitive environment. The concept of enterprise reliability is proposed to include the following areas of analysis: sustainability of economic growth, financial stability, industrial mobility and market stability. Each of the areas under consideration has its own aspects of analysis and indicators. The definitions of the proposed directions have been given, the need for their joint use in determining the reliability of the enterprise has been substantiated. The main content of the study is to analyze each component of the reliability of the enterprise, the proposed system of indicators that determine them, as well as the most favorable trends in the last time to improve the status and reliability of the enterprise. According to the results of the conducted research, the conclusion about the necessity of development of methods of reliability evaluation of engineering enterprises through the levels to create the structure of sectoral development opportunities has been made.
