The Atlantic Ocean houses three of these: the Northwest, Southwest and Northeast RMUs. The most studied is, so far, the Northwest RMU, but the other two have focused attention of researchers. In contrast, marine turtles from the African Atlantic region (Southeast) belong to a complex but little-known region. What is their role in the Atlantic? Are these RMUs connected? To understand these questions, research was made of reports and publications concerning the Northeast Atlantic (NEA) RMU. The asymmetry in information and available knowledge about NEA is high when compared to other RMUs. This demonstrates that there is still a lack of conservation programs besides Cape Verde, and that there is difficulty in transforming data (nesting ecology, molecular, telemetry, etc.) into publications. However, this issue is evident for other marine turtle species of East African Atlantic. There is a need for better scientific support, to enable local conservation programs to deliver data in reports, and even scientific publications. There are so many aspects of loggerhead’s life cycle that will only be unravelled by more and better supported studies. This is a paper that, by analysing the available information of the NEA loggerhead RMU, reflects the following steps to address in loggerhead conservation for the African Atlantic coast.展开更多

[Methods]International animal epidemics regionalization management experience and specific equine disease-free zone establishment were analysed and discussed based on the State and OIE principles. [Results]The regionalization management of specific equine disease-free zone with county administrative regions level of international recognition was established first in China,combined with the region＇s geographical barrier and animal health. [Conclusion]The aim is to to provide experience and reference for other areas to establish specific disease-free zone.展开更多

Urban decay is one of the serious and inevitable problems of urban management in all countries. This study has been conducted to analyze and assess the effect of regional factors on development of problematic urban contexts emphasizing on socio- economic indicators in Bandar Abbas City. Having urban macro-indicators at regional and country level, Bandar Abbas City faces various physical problems which problematic and old contexts are the most important of them that cover an area of 1033 hectares. Economic issues and heterogeneity within social contexts have expanded the mentioned problem in addition to physical problems. Methodology of this study has been analytical-descriptive, data collection method of documentary information has been gathered from relevant administrative organization such as Statistical Center of Iran, the Municipality and the Ministry of Housing and Urban Development, and survey data has been collected through 90 questionnaires. According to the obtained results of this study, it could be found that social, economic, political and managerial factors have had effects on formation of heterogeneous contexts and extensive migration during the current years has expanded problematic contexts of Bandar Abbas due to its specific regional conditions. Moreover, the obtained results of this study indicated that heterogeneous contexts had some features including fine-grained, inadequate access network, impervious, inferior materials and poor construction of buildings and lack of necessary infrastructure.展开更多

The state of Arizona was selected to evaluate the effects of the selected model parameters on the efficacy of RRWH since among the nine states the arid region of Arizona showed the least potential of meeting the outdoor water demand with rain harvested water. The analyses were conducted on a monthly basis across a 10-year projected period from 2015 to 2024. The results showed that RRWH as a potential source of water was highly sensitive to certain model parameters such as the outdoor water demand, the use of desert landscaping, and the percentage of existing houses with RRWH. A significant difference （as high as 37.5%） in rainwater potential was observed between the projected wet and dry climate conditions in Arizona. The analysis of the dynamics of the storage tanks suggested that a 1.0-2.0 m3 rainwater barrel, on an average, can store approximately 80% of the monthly rainwater generated from the rooftops in Arizona, even across the high seasonal variation. This interactive model can be used as a quick estimator of the amount of water that could be generated, stored, and utilized through RRWH systems in the U.S. under different climate conditions. The findings of such comprehensive analyses may help regional policymakers, especially in arid regions, to develop a sustainable water management infrastructure.展开更多
