This paper quantifies how international trade affects CO2 emissions and analyzes the welfare consequences of regulating the CO2 emissions from shipping. To this end the paper describes a model of trade and the environment, compiles new data on the CO2 emissions from shipping, and estimates key parameters using panel data regressions. Results show that the benefits of international trade exceed ...

Tiêm mao F18 đóng vai trò quan trọng giúp Enterotoxigenic Escherichia coli (ETEC) bám vào ruột và tiết độc tố gây bệnh tiêu chảy heo con sau cai sữa (post-weaning diarrhea, PWD). Vaccine là một cách thức hữu hiệu, kinh tế khả thi phòng chống ETEC trên heo. Việc phát triển vaccine uống, tạo miễn dịch niêm mạc thông qua nhắm trúng đích bào M đang được tâm. Nhiều nghiên cứu cho thấy Hsp60 có năng ...

One channel through which environment is damaged is consumption. To protect environment, various product standards are introduced all over the world. By using a new economic geography framework, this paper explores the effects of environmental product standards on environment in a North-South trade model. We examine a situation in which North unilaterally introduces an environmental product sta...

TLR4 is the main recognition receptor of bacterial lipopolysaccharides, which play an important role in innate and adaptive immunity. We used real-time PCR to analyze the tissue expression profile and differential expression of TLR4 in 4 pig populations (Escherichia coli F18-resistant Sutai, E. coli F18-sensitive Sutai, Large White, Meishan), in order to determine the role that the TLR4 gene pl...

the effect of economic growth and free trade on environment and transnational pollutions is one of the most important current discussions in the field of environmental economics. nowadays, the economics, social and developmental consequences of the climatic changes around the world is increasingly accepted and approved. in fact, the environment is considered as one of the key elements for susta...

many reports that appeared during the last 20 years have shown that atmospheric pollution causes serious damage to human health and to environment. electricity generation from fuel fossil is one of the major sources of pollution and considerable share of this damage. the price of electricity in iran, as in many other countries also, includes only the production of private costs and ignores any ...

Diarrhea and edema disease in weaned piglets due to infection by Escherichia coli F18 is a leading cause of economic loss in the pig industry. Resistance to E. coli F18 depends on expression of receptors on intestinal epithelial cells, and individual immunity. This study was conducted in Sutai pig E. coli F18-resistant and -susceptible full sib-pair individuals, identified on the basis of resou...

PURPOSE To investigate whether elevated glucose metabolism in neurofibroma, determined by [F18]-FDG-PET, is correlated with cell density in MRI, as expressed through the apparent diffusion coefficient. MATERIALS AND METHODS Patients diagnosed with neurofibromatosis type 1 and peripheral nerve sheath tumors (PNST) were enrolled in this prospective, IRB-approved study. After a single [F18]-FDG ...

sharp increase in oil price and the volatility in recent decades have attracted most researchers towards the field of energy. it seems not only the direct oil price, but also the uncertainty caused by the oil price volatility affect the raw oil supply. in this research the effect of oil price volatility on oil supply has been estimated using monthly time series data from january 1980 to septemb...
