Quantitative assessment of the extent, spatial distribution, and dynamics of aquaculture ponds is of utmost importance for sustainable economic development and scientific management of land and water resources in the coastal area. An object-oriented classification approach was applied to Landsat images acquired over three decades to investigate the long-term change of aquaculture ponds in the coastal region of the Yellow River Delta. The results indicated that the aquaculture ponds in the study area undergone a sharp expansion from 40.38 km^2 in 1983 to 1406.89 km^2 in 2015, and the fast expansion occurred during the period of 2010–2015 and 1990–2000. Natural wetlands, especially mudflat, and cropland were main land use types contributing to the increase of aquaculture ponds. The patches of aquaculture ponds were consequently prevalence in the north of the Yellow River Estuary and landscape metrics indicated an increase of the aquaculture ponds of the study area in the quantity and complexity. The expansion of aquaculture ponds inevitably had negative effects on the coastal environment, including loss of natural wetlands, water pollution and land subsidence, etc. The results from this study provide baseline data and valuable information for efficiently planning and managing aquaculture practices and for effectively implementing adequate regulations and protection measures.展开更多

Based on China＇s （imporO non-competitive input-output table and employment data provided by the World Input-Output Database （WIOD）, this paper has estimated China ＂s total employment and skill-specific employment between 1995 and 2009 and utilized structural decomposition method to investigate the effects of trade liberalization and outsourcing as two internationalization factors on China＇s job growth. Results indicate that between 1995 and 2009, China＇s total employment and skill-specific employment increased significantly, and the expansion of final output and particularly export expansion is a major driver of job growth, that the reduction in labor input coefficient is a major restraint of job growth, and that outsourcing is generally unfavorable to China＇s job growth. By specific product categories, their production internationalization effect of the production sectors of different types of products （aggregate effect of trade liberalization and variation in the level of outsourcing on employment variation） derives from different sources. For sectors of low technology products, their production internationalization effect mainly derives from the expansion of the share of export. For the production sectors of medium technology products, their production internationalization effect mainly derives from outsourcing expansion. By specific groups of workforce, low-skilled workforce is the most vulnerable to the impact of production internationalization, medium-skilled workforce is subject to relatively small effect, while the effect on highly-skilled workforce is negligible.展开更多

Renewable energy plays a decisive role in a cleaner energy production with less environmental impacts. In this new world scenario, several countries create incentive programs aiming to increase the renewable energy share in their energy balance. Biogas is an interesting example of a smart and rational use of organic waste material. Nevertheless, international experience shows that its production relays mainly on government incentives. This paper investigates what the Brazilian government role is to introduce and promote the biogas industry in the country. We estimate the production of agricultural waste energy using biogas derived from cattle and swine waste and analyze the Brazilian legal and regulatory framework for renewable energy, focusing on biogas production, transport and sale. The results point to an unexplored potential of the use of cattle and swine waste for biogas production in Brazil. However, this potential can only become a reality if some legal and regulatory issues are solved. Brazilian government agenda has to include not only filling the legal and regulatory blanks but also creating incentives for the use of biogas.展开更多

More than 26% of energy in Iran is consumed by industry sector, in which cement section is an important subsectors highly depending on energy. Cement section is so dependent on energy, that more 15% of the related energy is consumed in this section, and its present conditions of energy consumption need a serious revision. Production management, changing the ingredients, finding alternative energy strategies, and importing modem technologies can result in reduction of energy consumption in this section. In this study, while investigating energy consumption of various machineries in the form of electricity and heat in a cement factory, the authors have studied the strategies for decreasing energy consumption in every stage of the production process. Recent studies in the field of cement industry are indicative of recent changes in production methods with priority of reducing energy consumption. Among these changes, we can refer to replacing wet method by dry method, or developing pre-heating center and pre-calcinators. In cement industry, nowadays, not only there is an emphasis on controlling the energy consumption for lower production costs, but as production of every 1 kg of cement gives out more than 0.7 kg CO2 and other pollution particles, environmental issues are also seriously considered. Therefore, if we use alternative fuels with less carbon in their structural formula, besides decreasing energy consumption and costs, there will be less pollutions in the environment as well.展开更多

A number of agronomic practices are known to affect the infection and mycotoxin production by these Fusarium species in cereal grains. A field study was conducted to compare the natural occurrence of DON in durum wheat grown under conventional （n = 67 samples） and organic （n = 50） farming conditions during two consecutive crop years. DON mean levels were 95 and 194 μg/kg in conventional and organic durum wheat, respectively. The incidence and levels of DON were higher in the second crop year due to higher rainfall （〉 100 mm） during flowering. Overall, organically managed farming system may provide Lsome reduction in DON levels in durum wheat, which could be attributable to the lower intensity of cultivation in addition to the different system of cropping rotation. However, favourable weather conditions are likely to be more important for DON contamination than crop system.展开更多

This study focused into the issue of what happened with regard to the quality of products in the supply chain SME products. This study aims to describe how the culture of quality in the supply chain of SMEs and their role in contributing to the lack of SME products. The study involved 128 SMEs in the food processing industry cluster and garment industry. The research uses qualitative method with case study approach. The results showed an average internal quality culture reached 3.62661 supply included in the category enough. Of the five industry cluster, a culture of quality in the internal supply chain is the best T-shirt industry （4.3385） in both categories, while other four clusters exist in enough categories, with grades： hoods （3.661）, soy crisps （3.6635）, cassava chips （3.64）, and the last chips fish balls （2.829）. The low average internal quality culture supply mainly is in industrial processing of cassava chips and chips fish balls. One reason is the low awareness of quality. There is no technology and equipment adequate to safeguard the stability of quality. The upper most excellent quality culture occurred in the supply chain, where the product is controlled by big industry, is the industry shirts （4.018）, soy crisps （3.613）, and hoods （3.473）, while when in the upstream industry controlled by small or SMEs, there is deterioration in the cultural values of quality： cassava chips （2.917） and chips fish balls （2.781）. For downstream, 100% controlled by SMEs, there is an average value of quality culture 3.5662.展开更多
