METHODS:For the development of liver cirrhosis and portal hypertensive gastropathy,60 rats underwent ligation of the left adrenal vein and complete devascularization of the left renal vein,followed by phenobarbital and carbon tetrachloride(CCl4) administration.After two weeks of CCl4 administration, the rats were randomly separated into two groups.In group A,propranolol was continuously administered intragastrically throughout the study,whereas in group B normal saline(placebo)was administered instead. Hemodynamic studies and vascular morphometric analysis of gastric sections were performed after complete induction of cirrhosis. RESULTS:Vascular morphometric studies showed higher numbers of vessels in all mucosal layers in the control group.Statistical analysis revealed a significantly higher total vascular surface in the control group compared to the propranolol group,but with no statistically significant difference between the mean vascular surfaces between the groups.Our study clearly shows that the increased mucosal blood flow is manifested by a marked increase of vessel count. CONCLUSION:Early propranolol's administration in portal hypertensive cirrhotic rats seems to prevent intense gastric vascular congestion that characterizes portal hypertensive gastropathy.展开更多

This article analyzes the problems of spatial planning and regional strategy caused by the wrongly-set primary goal of economic development; it states that the three-fold objective of competitiveness, sustainability, and welfare fairness shall be the principal for China to implement the spatial regulation in the new era; it discusses about theoretical thoughts and technology framework of conducting the ′Major Function Oriented Zone′ based on their different major functions that each region plays in urbanization and industrialization, ecological constructions, grain productions, and protection of natural and cultural heritages; it introduces the new concept of ′Major Function Oriented Zone′ that include the major functions category, the stereo regional equilibrium mode, the two-level zoning specification, and the territorial development intensity; it offers a zoning scheme that defines development-optimized and development-prioritized zones as regions with massive urbanization and industrialization, development-restricted zones as ecological constructing or grain producing regions, development-prohibited zones as natural and cultural heritage protecting regions; and finally it addresses the main obstacle for implementing ′Major Function Oriented Zone′, which is the institutional arrangement of the supreme goal of high GDP growth rate that is currently being implemented.展开更多

To address this problem, the world is in an era of new round energy transformation, and the existing energy structure is being reformed. In this paper, according to the Chinese government's action plan for coping with climate change, the China's wind energy sustainable development goals and development route are discussed, and the countermeasures and suggestions are put forward. Wind energy is currently a kind of important renewable energy with matured technology which can be scale-up developed and put into commercial application, and in this transformation, wind energy will play a key role with other non-fossil energy sources. The development and utilization of wind energy is a systematic project, which needs to be solved from the aspects of policy, technology and management. At present, China is in the stage of transferring from "large wind power country" to "strong wind power country", opportunities and challenges coexist, and the advantages of China's socialist system could be fully used, which can concentrate power to do big things and make contribution in the process of realizing global energy transformation.展开更多

The extreme indices of summer days (SU), frost days (FD), and growing season length (GSL) for temperature and simple daily intensity index (SDII), number of days with precipitation ≥10 mm d-1 (R10), and consecutive dry days (CDD) for precipitation are used as the indicators of the extremes. The results show that the indices simulated by RegCM3 in the present day show good agreement with the observed. A general increase in SU, a decrease in FD, and an increase in GSL are found to occur in the next 20-30 years over China. A general increase in SDII, an increase in R10 over western China, and a decrease in R10 in north, northeast, and central China are simulated by the model. Changes in CDD are characterized by a decrease in the north and an increase in the south and the Tibetan Plateau.展开更多

However, most residents are ordinary people. Therefore, it is necessary to change the awareness of sustainable living environments, not only on the construction side but also the residents. In recent years, the number of cases of residents' participation in planning, maintaining, and repairing increased. However, sometimes youths and children, who might spend a lifetime longer than adults in a city after the developments have been done, are not included in this "Residents". Conceming youth and children's participation, CFC (child friendly city) is one of the good practices for sustainable development. It was launched by UNICEF (United Nations Intemational Children's Emergency Fund) and UN-Habitat in the Habitat II in 1996. City governments, especially in European countries, started to view CFC as their key concept for preservation and/or sustainable development. CFC means not only being "Children" friendly but also "All people" friendly. Various effects have been reported since the Historic Cities/districts included CFC in their city planning as a common concept, especially in education, community re-development, and operation and maintenance by the community. It is expected that better city planning in preservation and sustainable development can be achieved by adding CFC concept. In this research, an ideal way of city planning involving resident participation and the possibility in the future are analyzed based on case studies. Then a strategy of sustainable development and community planning involving youth and children's participation is proposed.展开更多

This is a study about links between the two laws and their touch points and their differences. It will be seen that the legislative actions follow a common sense but are targeted for different acts of management of cultural heritage. We will be able to observe how legislation, whether it is Argentine or Brazilian, works as a mediator between the reclaiming of heritage (as in the acknowledgement of cultural practices) and the government actions towards cultural heritage. This shows that Argentina, despite not creating specific federal legislation regarding intangible cultural heritage, is aware of the need to preserve the cultural events that belong in this category of heritage展开更多

The analysis is based on a high-resolution climate change simulation conducted by a regional climate model (the Abdus Salam International Center for Theoretical Physics (ICTP) RegCM3) driven by the global model of Center for Climate System Research (CCSR)/National Institute for Environment Studies (NIES)/Frontier Research Center for Global Change (FRCGC) MIROC3.2_hires (the Model for Interdisciplinary Research on Climate) under the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A1B scenario. Validation of the model performances is presented first. The results show that RegCM3 reproduces the present-day distribution of the Kppen climate types well. Significant changes of the types are found in the future over China, following the simulated warming and precipitation changes. In southern China, the change is characterized by the replacement of subtropical humid (Cr) by subtropical winter-dry (Cw). A pronounced decrease of the cold climate types is found over China, e.g., tundra (Ft) over the Tibetan Plateau and sub-arctic continental (Ec) over northeast China. The changes are usually greater in the end compared with the middle of the 21st century.展开更多

In fact, the endowment culture plays an irreplaceable part in the social old-age care system. In the period of social transition, the excellent traditional old-age pension culture is destroyed, which makes the cultivation of the old-age social fashion imminent. The atmosphere of respecting the old and establishing a harmonious generation relationship is an important cultural guarantee to establish "five old" and build a harmonious society, in which our country or government bears inescapable responsibilities.展开更多

One of these subgenres is Amharic folk poetry which is permeated with the political, social, economic, and cultural legacies of successive Ethiopian governments that rise and demise. The image of these governments was determined by their integrity, vision, and responsiveness to the aspirations of the populace. This study was designed to determine the popular image of the imperial governments of Menelik II and Haile Selasse I as reflected in Amharic folk poetry. Without prejudice to some odes which invariably idealise the vision of these monarchs, the politically-inspired Amharic folk poetry is found to be critical of the feudal status quo thus perpetuating its negative images. This underpins the partial unpopularity of Menilik and Haile Selasse. However, these critical gestures would by no means undermine their monumental contributions to the reunification, modernization, and survival of Ethiopia. Thus, the contemporary Amharic folk-poetry is neither iconoclastic nor idealistic but an impassioned allegory of the nation-state.展开更多
