It means not only economic growth butalso changes towards a better direction in economic structure , social structure , relation between human soci-ety and environment, and even political structure. Present development should not damage the environmentbut leave the same or an improved natural resource endowment as a bequest to the future. This is the devel-opment with environmental sustainability. In this paper the characteristics of rural development were reex-amined, and what environmental sustainability means and how to measure it were explicitly presented.

Solid Waste and/or waste in general is an artefact of human activities that can spring from individuals, families, community, commercial/industrial operations etc. This study is a qualitative investigation, and it is intended to gather an inclusive knowledge of solid wastes management for better public health in Freetown, the Capital City of Sierra Leone. Statistical analysis was employed to observe numerical representations on a wide range of selected data. In an attempt to achieve the aim of this research project, reviews of available online resources were exploited, and juxtaposed with everyday knowledge in the existing state of the Freetown’s municipality solid waste management. The study revealed that residents in Freetown produce an average 0.45 kg of solid waste per individual per day. It was further established that biodegradable/organic matters comprise approximately 75% to 85% of total waste stream along with assorted retired furniture, scarp metals and plastic bags as most important recyclable elements. The hitches connected with municipal solid waste management in Freetown have become palpable, spanning from the past decade to date. Among many other factors, an upsurge influx urbanisation after the 11 years brutal civil war that ended in 2001, combine up with insufficient approved dumping sites for waste disposal and institutional incapability stand out. In this project, the contemporary approach of solid waste disposal in Freetown was carefully assessed with efforts to bring out the most feasible alternatives of solid waste disposal and acclaim ways of refining its activities. It was concluded from the study that, solid wastes in the Freetown Municipality must be tackled in a synergetic approach. That is, government corroborating with private solid waste managing actors so as to enhance an excellent better-public health, sustainable environmental, urban economic development and a resourceful energy paradigm.展开更多

In total, 139 monozygotic and 95 dizygotictwin pairs aged from 5 to 18 years were recruited.The twin correlations of total hand and wrist scoresfor monozygotic (MZ) and dizygotic (DZ) twins were0.71 and 0.36, respectively. Bivariate modelanalysis showed moderate genetic correlations onlyfor total skeletal maturity vs. weight and totalskeletal maturity vs. waist circumference (r, 0.51and 0.46, respectively). Our findings demonstratedthat genetic factors played important roles in bonedevelopment of the hand and wrist in Chineseyoung twins, and that these genetic effects mightbe distinct from those influencing anthropometricmeasures.展开更多

In this regard,on June 24,the Standing Committee of National People's Congress deliberated the draft of Energy Saving Law,according to which China is to take"resources saving"as a basic national policy.This is a key issue to the long-term benefits of China.With relevant questions,China's Foreign Trade interviewed Dr, Yonglong L(?),Secretary-general,Chinese Committee for SCOPE(Scientific Committee on Problems of the Environment/ICSU).and Research Professor at the Chinese Academy of Sciences.

With economic globalization and sci- entific and technological progress, it is more and more important to educate and protect environmental rights world- wide. As a large developing country, China has significant responsibilities in the field of global environmental safety. However, the awareness and status of environmental rights protection are still not suited to people's demands for environmental rights, making it an important task to carry out scientific planning and environmental rights edu- cation and improve citizens' enjoyment of environmental rights. We propose to start from defining the constitutional status of environmental rights and pro- mote the education and protection of environmental rights at the same time, so as to enhance mutual influence and contribute to creating a good environ- ment for mankind.展开更多

At weaning piglets are presented with a vast and diverse range of microbial and dietary/environmental antigens. Their ability to distinguish between antigens and mount a protective response to potential pathogens and to develop tolerance to dietary antigens is critical to their survival and failure to do so is reflected in the high incidence of morbidity and mortality in the post-weaning period. A growing recognition that the widespread use of antibiotics to control infection during this critical period should be controlled has led to detailed studies of those factors which drive the development of the mucosal immune system, the role of gut microbiota in driving this process, the origin of the bacteria that colonise the young piglet's intestine and the impact of rearing environment. This review briefly describes how the mucosal immune system is equipped to respond "appropriately" to antigenic challenge and the programmed sequence by which it develops. The results of studies on the critical interplay between the host immune system and gut microbiota are discussed along with the effects of rearing environment. By comparing these with results from human studies on the development of allergies in children, an approach to promote an earlier maturation of the piglet immune system to resist the challenges of weaning are outlined.展开更多

We applied the proposed model to Xuzhou City, Jiangsu Province, China. Landsat-5 Thematic Mapper(TM) images from 1998 to 2010 and digital elevation model(DEM) data with a 30-m resolution were used to calculate the values of the six evaluation factors. The HSEDI value in Xuzhou City was found to be between 2.24 and 8.10 from 1998 to 2010, and it was further divided into five levels, uninhabitable, moderately uninhabitable, generally inhabitable, moderately inhabitable, and inhabitable. The best HSEDI value was in 2007. The generally inhabitable region was about 100.98 km^2, covering 30.87% of the total area in 2007; the moderately inhabitable region was about 170.58 km2 covering 52.15% of the total area; the inhabitable region was about 32.03 km^2, covering 9.79% of the total area; the percentage of the uninhabitable region was zero; and that of the moderately uninhabitable region was very small, less than 1.00%. Moreover, we analyzed the habitability in the respect of spatial patterns and change detection. Results show that the degraded regions of habitability quality are mainly located in the urban fringe and the improved regions are mainly located in the main urban and rural areas. Reason for the degraded habitability quality is the rapid progress of urbanization. However, the increase in urban green spaces and the construction of the main urban area promoted the improved habitability quality. Besides, we further analyzed socio-economic and socio-demographic data to confirm the results of the habitability analysis. The results indicate that the human settlement in Xuzhou City is in a satisfactory condition, but some efforts should be made to control the possible uninhabitable and moderately uninhabitable regions, and to improve the quality of the generally inhabitable regions.展开更多

Two concepts, multi agent system architecture and multi agent system architecture prototype are brought forward, and the method of descrbing the relation between agents using the concepts is explored. The structure and components are designed. Based on the fact that cooperation between distributed agents is erratic, a controlled natural language communication function is designed and realized. Applying the offered interfaces, the user′s workload consumed in agent communication and management is reduced, and at the same time, robustness of the multi agent system is improved.展开更多

Different from these, this paper points out that green barriers, evolving from the background of sustainable development theory and the principle of environment protection, have positive effect on ideology, international institutional arrangement and innovation stimulation. Demonstrating the rationality of green barriers, the paper puts forward that green barriers should be regarded as the stimulation for technology innovation and industrial restructure rather than obstacles. The best way to surmount the green barriers for Chinese government and enterprises is to implement circular economy and clean production so as to achieve the harmony of trade, environment and economic development.展开更多
