Grid-connected PV power station is one of the most important applications of photovoltaic system, generating low cost and high-quality electric power without non-renewable energy, as well as relaxing the tightness of daytime power demand. In China, it is usually installed on remote open area for low cost to guarantee the abundant solar power. However, this kind of place usually comes with tough weather conditions. In this paper, the property of the PV test field is estimated by its output characteristic. One inevitable and two avoidable reasons which affect the plant output are proposed. Firstly, the inevitable factor is weather, and the assessment analyzing the performance of PV power system under different weather conditions, such as sunny, cloudy, rainy and snowy is then presented. Secondly, losses owing to the mounting type and partial shading, which can be reduced by well designing and installing, are also mentioned and analyzed.

Ernst Mahle is a German-born Brazilian composer, conductor, and music educator who occupies the chair number 6 of the Academia Brasileira de Música. He is also a former vice-president of the Sociedade Brasileira de Música Contemporânea. He was born on January 3rd 1929 in Stuttgart and spent most of his childhood in Bluendz, Austria. Following the World War II, the city of Bluendz would host concerts by the most prominent students of the Conservatoire national de musique de Paris. Impressed by the dexterity of such players, Mahle decided to pursue piano and composition studies, and at age 20 he was accepted at the Staatliche Hochschule für Musik und Darstellende Kunst Stuttgart in the class of Austrian composer Johann Nepomuk David. His studies in Stuttgart ended quickly, only one year later, when his family moved to São Paulo, Brazil, in 1951. Nevertheless, Mahle developed a special interest in modal music during this period after being introduced to the music of Béla Bartók.

The water saving project, Saragossa, water saving city. 50 Good Practices aims to resolve the problems of water scarcity with a different approach which is cheaper, more ecological and free from social conflicts: increasing the efficiency of its use. It seeks to provide a model to be imitated by the more than 9,000 Spanish towns which waste over 1,500 hm3 of water per year. In 1997 a collective challenge was put forward: to save 1 billion litres of water in one year. In fact 1,176 billion litres was saved, 5.6% of domestic consumption. 50 Good Practices in efficient water use are currently being worked on. As we have demonstrated in the project, technological change is produced via imitation. The Hospital Royo Villanova, with a consumption of 382 litres per bed per day, is one such example to imitate; this is one of the best ratios in the world. Today Saragossa has one of the lowest ratios of domestic consumption per inhabitant per day in Spain: 96 litres.

The fast urbanization in many regions of the world has generated a high competition between cities. In the race for investments and for international presence, some cities have increasingly resorting to the territorial marketing techniques like city branding. One of the strategies of recent years has been to use of creativity and / or labeling of creative city for the promotion of its destination. This phenomenon raises a question whether the city branding programs have worked in accordance with the cultural industries of the territory or if such labels influence the thought of tourists and locals. This paper begins by placing a consideration of the UNESCO Creative Cities Network (UCCN) and the strategies of the Territorial Marketing Program of the city of Lyon in France, Only Lyon. It also raises the question the perception of the target public to each of the current actions through semi-structured interviews which were applied between May and August 2015. Finally, I will try to open a discussion the brand positioning adopted by the city of Lyon

[222 pp, RRP: £18.75, ISBN: 978-1-910781-22-7]The idea of discovering or creating a form of uniqueness to differentiate a place from others is clearly attractive. In this regard, and in line with Ashworth (2009), three urban planning instruments are widely used throughout the world as a means of boosting a city’s image: (i) personality association - where places associate themselves with a named individual from history, literature, the arts, politics, entertainment, sport or even mythology; (ii) the visual qualities of buildings and urban design, which include flagship building, signature urban design and even signature districts and (iii) event hallmarking - where places organize events, usually cultural (e.g., European Capital of Culture, henceforth referred to as ECoC) or sporting (e.g., the Olympic Games), in order to obtain worldwide recognition.

Writers of the early nineteenth century sought to find new ways of writing about the urban landscape when first confronted with the phenomena of London. The very nature of London's rapid growth, its unprecedented scale, and its mere difference from any other urban centre throughout the world marked it out as demanding a different register in prose and poetry. The condition of writing the city, of inventing a new writing for a new experience is explored by familiar texts of urban representation such as by Thomas De Quincey and William Wordsworth, as well as through less widely read authors such as Sarah Green, Pierce Egan, and Robert Southey, particularly his fictional Letters from England.

Every child has a right to an education. In the United States, the issue is not necessarily about access to a school but access to a quality education. With strict compulsory education laws, more than 50 million students enrolled in primary and secondary schools, and billions of dollars spent annually on public and private education, American children surely have access to buildings and classrooms. However, because of a complex and competitive system of shared policymaking among national, state, and local governments, not all schools are created equal nor are equal education opportunities available for the poor, minorities, and underprivileged. One manifestation of this inequity is the lack of qualified teachers in many urban and rural schools to teach certain subjects such as science, mathematics, and technology. The purpose of this article is to describe a partnership model between two major institutions (The American Museum of Natural History and The City University of New York) and the program designed to improve the way teachers are trained and children are taught and introduced to the world of science. These two institutions have partnered on various projects over the years to expand educational opportunity especially in the teaching of science. One of the more successful projects is Seminars on Science (SoS), an online teacher education and professional development program, that connects teachers across the United States and around the world to cutting-edge research and provides them with powerful classroom resources. This article provides the institutional perspectives, the challenges and the strategies that fostered this partnership.

Abstract The bulk of the scholarly literature on city-regions and their governance is drawn from contexts where economic and political systems have been stable over an extended period. However, many parts of the world, including all countries in the BRICS, have experienced far-reaching national transformations in the recent past in economic and/or political systems. The national transitions are complex, with a mix of continuity and rupture, while their translation into the scale of the city-region is often indirect. But, these transitions have been significant for the city-region, providing a period of opportunity and institutional fluidity. Studies of the BRICS show that outcomes of transitions are varied but that there are junctures of productive comparison including the ways in which the nature of the transitions create new path dependencies, and way in which interests across territorial scales soon consolidate, producing new rigidities in city-region governance.

Trade is a form of business that is run by many people around the world, ranging from trading various kinds of daily necessities or primary needs, to selling the need for luxury goods for human satisfaction. For that, to overcome the many needs of life, they try to outsmart them buy products that are useful, economical and efficient. One of the markets they aim at is the second-hand market or the so-called trashy market. As for a trader at a trashy market, they aim to sell in the used goods market with a variety of reasons. These reasons include; first, because it is indeed to fulfill their needs. Second, the capital needed to trade at trashy markets is much smaller than opening a business where the products come from new goods. Third, used goods are easily available and easily sold to buyer. Here the researcher will discuss the behavior of Muslim traders in a review of Islamic business ethics (the case in the Jagalan Kediri Trashy Market). Kediri Jagalan Trashy Market is central to the sale of used goods in the city of Kediri. Where every day there are more than 300 used merchants who trade in the market. The focus of this research is how the behavior of Muslim traders in the Jagalan Kediri Trashy Market in general. Then, from the large number of traders, of course not all traders have behavior in accordance with Islamic business ethics, as well as traders who are in accordance with the rules of Islamic business ethics. This study aims to determine how the behavior of Muslim traders in the Jagalan Kediri Trashy Market in buying and selling transactions and to find out how the behavior of Muslim traders in the Jagalan Kediri Trashy Market in reviewing Islamic business ethics. Key Words: Trade, loak market, Islamic business
