In high plants, the LHC gene family constituting the light-harvesting complex ofphotosystems I and II. the transfer of solar energy using light-harvesting chlorophyll includes LHCA and LHCB sub-families, which encode proteins Zostera marina L. is a monocotyledonous angiosperm and inhab- its submerged marine environments rather than land environments. We characterized the Lhca and Lhcb gene families of Z. marina from the expressed sequence tags (EST) database. In total, 13 unigenes were annotated as ZmLhc, 6 in Lhca family and 7 in ZmLhcb family. ZmLHCA and ZmLHCB contained the conservative LHC motifs and amino acid residues binding chlorophyll. The average similarity among mature ZmLHCA and ZmLHCB was 48.91% and 48.66%, respectively, which indicated a high degree of diver- gence within ZmLHChc gene family. The reconstructed phylogenetic tree showed that the tree topology and phylogenetic relation- ship were similar to those reported in other high plants, suggesting that the Lhc genes were highly conservative and the classification of ZmLhc genes was consistent with the evolutionary position of Z. marina. Real-time reverse transcription (RT) PCR analysis showed that different members of ZmLhca and ZmLhcb responded to a stress in different expression patterns. Salinity, temperature, light intensity and light quality may affect the expression of most ZmLhca and ZmLhcb genes. Inorganic carbon concentration and acidity had no obvious effect on ZmLhca and ZmLhcb gene expression, except for ZmLhca6.展开更多

Firstly, a mathematical model describing the interaction between tumor cells and immune system under external fluctuations and periodic treatment is established based on the stochastic differential equation. Then, sufficient conditions for extinction and persistence of the tumor cells are derived by constructing Lyapunov functions and Ito's formula. Finally, numerical simulations are introduced to illustrate and verify the results. The results of this work provide the theoretical basis for designing more effective and precise therapeutic strategies to eliminate cancer cells, especially for combining the immunotherapy and the traditional tools.展开更多

This paper focused on tourists' environmental responsible behaviors in the context of all-for-one tourism. On the basis of clarifying the connotation, dimension and driving factors of tourists' environmental responsible behaviors, this paper firstly analyzed the relationship between all-for-one tourism and tourists' environmental responsible behaviors, and proposed that the development of all-for-one tourism was an important path to optimize and upgrade China's tourism industry and a new concept of sustainable development of tourism industry. The emergence of all-for-one tourism has formed a new tourism trend, which will drive tourists to behave more civilly. Tourists' environmental responsible behaviors are a "subject and share" concept, and from tourists' point of view, all-for-one tourism development is the most basic requirement. Secondly, based on the theory of "value-belief-norm", this paper focused on the strengthening mechanism of "interaction effect" between all-for-one tourism and tourists' environmental responsible behaviors, and put forward the idea of "double internalization strengthening" to guide tourists' environmental responsible behaviors from being passive to active, from individuals to groups. Finally, this paper discussed the promotion of environmental responsible behaviors of tourist's specific strategies from two aspects, "external drive" and "internal drive" to enhance the level of all-for-one tourism construction and strengthen the environment responsibility of tourists. "External drives" were as follows:(1) to make a scientific development plan to implement the "host and guest sharing" mechanism;(2) to optimize the landscape, the environment, services, enhance the local attachment of visitors;(3) to improve the infrastructure system, pay attention to the details of visitors' experience;(4) to strengthen environment education and publicity, deepening the quality of tourists' civilization construction, and strengthen the environmental responsible behaviors of tourists. "Internal drives" were as follows:(1) to strengthen the sense of environmental responsibility of tourists;(2) to establish a model of environmental responsible behaviors;(3) to strengthen the supervision of environmental responsible behaviors.展开更多

From the perspective of economic benefit and industrial linkage, this paper discusses the issue of inter-industry allocation of environmental responsibilities. Based on input-output model and three responsibility principles (producer responsibility, consumer responsibility and shared responsibility), this paper develops seven industrial environmental responsibility indicators and conducts an empirical analysis on the S02 emission responsibilities at China's industry level. Results indicate that all these indicators can avoid the double calculation of environmental responsibilities and results using different indicators have significant differences. Some industries such as power, heat production and supply may have little difference of the relative ranking of environmental responsibility under different indicators, but the magnitude of specific assumed responsibilities may have significant changes. Environmental responsibilities of some other industries (such as construction) may seem not important under certain indicators but can be among the most significant under some other indicators. More importantly, despite close connections between these indicators, they reflect different mechanisms of environmental responsibility allocation and have totally different policy significance.展开更多

We also discussed the responses of fishes to the quick changes in Arctic climate. The results showed that a total of 41 species in 14 families were recorded in these waters. The dominant species were Hippoglossoides robustus, Boreogadus saida, Myoxocephalus scorpius, Lumpenus fabricii, and Artediellus scaber. There were 35 coldwater species, accounting for 85.37%, and six cold temperate species, occupying 14.63%. The habitat types of fish could be grouped as follows: 35 species of demersal fishes, five benthopelagic fishes, and one pelagic fish. The Shannon-Wiener diversity index (H') (range between 0 and 2.18, 1.21 on average) was not high, and descended from south to north. Climate change has caused some fishes to shift along their latitudinal and longitudinal distribution around the Arctic and Subarctic areas, and this could lead to the decline of Arctic fishery resources.展开更多

As greenhouse gas concentration of the atmosphere has reached the 400ppm threshold of a 2°C global warming on 9 May 2013 and irreversible tipping points of the climatic system at some point of time have got even more likely, the question of the individual contribution to climate change becomes more and more virulent. For a long time, the absorption capacity of the environment has been regarded as limitless, and based on this perception, the economic entities used the environment for hundreds of years without constraints. Today, with progress of scientific knowledge, we are now aware of the possible negative impacts of climate change to environmental, economic and social systems on Earth. This awareness, however, did not lead to a significant change of individual behavior, because the perceived individual contribution to both the anthropogenic cause of climate change and its mitigation is still regarded as marginal. To encounter this misperception or “diffusion of environmental responsibility”, this article presents an alternative calculation of the individual contribution to climate change taking the incremental approach to a tipping point or a 2°C global warming threshold into account.展开更多

This is a very important feature of the Portuguese city. The Iberian Peninsula comprised by Spain and Portugal belongs to very different environments: the Atlantic and Mediterranean sea. This position is responsible for a series of highly contrasted regions. The external forces presented in each region, influence the shape, location and orientation, not only of individual buildings but of whole villages in such a way that we can identify pattems of construction in different natural regions. There is in fact, a remarkable correspondence between climate and urban type which is useful to identify for planning the different regions. The legacy of industrial city, as in other parts of the world, has changed this close connection between geography and architecture, with consequences not only in environment but especially for the identity of urban spaces. Bioclimatic urbanism is not just a question of sustainability or survival. It is also a question of local identity and variety. There is in fact a relationship between cultural process and environment responsive which we can learn from the structures of the past -- the pre-industrial city. We believe that the reinterpretation of the traditional city pattems forms a language which can be used as a design process for recovering urban landscape.展开更多

文摘Based on trawl surveys in the Bering Sea and Chukchi Sea during the 2010 Chinese National Arctic Research Expedition, fish biodiversity characteristics, such as fish composition, dominant species, biodiversity, and faunal characteristics were conducted. We also discussed the responses of fishes to the quick changes in Arctic climate. The results showed that a total of 41 species in 14 families were recorded in these waters. The dominant species were Hippoglossoides robustus, Boreogadus saida, Myoxocephalus scorpius, Lumpenus fabricii, and Artediellus scaber. There were 35 coldwater species, accounting for 85.37%, and six cold temperate species, occupying 14.63%. The habitat types of fish could be grouped as follows: 35 species of demersal fishes, five benthopelagic fishes, and one pelagic fish. The Shannon-Wiener diversity index (H') (range between 0 and 2.18, 1.21 on average) was not high, and descended from south to north. Climate change has caused some fishes to shift along their latitudinal and longitudinal distribution around the Arctic and Subarctic areas, and this could lead to the decline of Arctic fishery resources.
文摘This research is aimed at investigating Corporate Environmental Responsibility in Manufacturing Enterprises in the Akaki River basin on protecting the urban environment with particular emphasis on twenty selected industries.To attain its objective,the study employed a mixed methods research approach.Data were collected by employing tools such as questionnaire,key informant interview,group discussions and observation.The findings of the research show that corporate environmental responsibility is very low.The majority of Large Scale Industries encompassed in the survey did not show considerable effort on protecting the environment responsibly.The reasons identified by this research are among others the absence of corporate environmental responsibility,low pressure from the enforcing institutions,and lack of financial and human resources.As a result,the Akaki River is highly polluted mainly through toxic industrial effluents released with little or no prior treatment.The consequences are countless.The populations living across the river are facing health deteriorations and economic damages.Based on the findings of this study,setting up strong institutions which are capable of developing new laws and implementing the existing environmental legal framework is commended.

文摘Epilepsy is a neurodegenerative disease that interrupts the normal electrical activity of the brain and promotes abnormal wiring in this organ.Epileptic seizures are often associated with significant changes in the functioning of the autonomic nervous system(ANS).
文摘Climate change is one of the most important challenges of the 21st Century. As greenhouse gas concentration of the atmosphere has reached the 400ppm threshold of a 2°C global warming on 9 May 2013 and irreversible tipping points of the climatic system at some point of time have got even more likely, the question of the individual contribution to climate change becomes more and more virulent. For a long time, the absorption capacity of the environment has been regarded as limitless, and based on this perception, the economic entities used the environment for hundreds of years without constraints. Today, with progress of scientific knowledge, we are now aware of the possible negative impacts of climate change to environmental, economic and social systems on Earth. This awareness, however, did not lead to a significant change of individual behavior, because the perceived individual contribution to both the anthropogenic cause of climate change and its mitigation is still regarded as marginal. To encounter this misperception or “diffusion of environmental responsibility”, this article presents an alternative calculation of the individual contribution to climate change taking the incremental approach to a tipping point or a 2°C global warming threshold into account.
文摘This paper discusses two questions:Is a specific part on ecological and environmental responsibility a common practice and trend in foreign environmental codes?How are its compiling principles and scope of work determined,and would administrative legal responsibility be arranged elsewhere than in this part?
文摘The subject of the present work is the study of the relationship between the city shape and its geographical and climatic context. This is a very important feature of the Portuguese city. The Iberian Peninsula comprised by Spain and Portugal belongs to very different environments: the Atlantic and Mediterranean sea. This position is responsible for a series of highly contrasted regions. The external forces presented in each region, influence the shape, location and orientation, not only of individual buildings but of whole villages in such a way that we can identify pattems of construction in different natural regions. There is in fact, a remarkable correspondence between climate and urban type which is useful to identify for planning the different regions. The legacy of industrial city, as in other parts of the world, has changed this close connection between geography and architecture, with consequences not only in environment but especially for the identity of urban spaces. Bioclimatic urbanism is not just a question of sustainability or survival. It is also a question of local identity and variety. There is in fact a relationship between cultural process and environment responsive which we can learn from the structures of the past -- the pre-industrial city. We believe that the reinterpretation of the traditional city pattems forms a language which can be used as a design process for recovering urban landscape.
文摘China has made the miracle of rapid development in GDP in recent 20 years. However, the economic development is at the cost of environment and resources, which will decrease the speed of economic development in return. China should gradually change the guideline from simply pursuing GDP growth to harmonious development, and establish a new set of performance-evaluating system, the resource-saving responsibility system as soon as possible.
