[ Metbod] By employing polyacrylamide gel electrophoresis method, the expressions of AMY and SOD isozymes during seed germination process were analyzed. ~ Result] The main AMY bands remained strong during the whole peri- od and a new band A2 appeared in the middle and late period of seed germination. Some new SOD bands occurred at the early stage, then be- came weak or disappeared in the middle period, and band S6 became intense in the late peried. [ Conclusion.] The expression of AMY and SOD isozyme gene has temporal difference during germination of E. henryi Oliv seeds.展开更多

Theoretical basis of argument is the opposite of anthropocentrism and non- anthropocentrism. Ecological ethics controversy concerns the core issue of the relationship between human and nature of the ecological ethics about nature, to correctly understand and deal with the relationship between mankind and nature, ecological ethics and ecological ethics is the starting point and destination debates.展开更多

Over the years, their distinct way of living have further accentuated their culture. The paper discusses the Igbo cultural landscape region which comprises of rural autonomous communities made up of clusters of kindred and villages. In spite of the existence of the townships serving as trade, political and administrative centers for more than one century, the rate of urbanization has been very slow thereby affecting the development of the communities physically, economically and socially at astonishing rates consuming farmlands and traditional community boundaries. This paper is aimed at creating awareness on the unique regional growth pattern in Igbo land heavily dependent on cultural and natural heritages for purpose of determining adaptable regional planning strategies for such vibrant cultural region. It has examined the key issues and suggested a way forward to a more sustainable development of the region.展开更多

These cities are regarded as an attractive area of residence, among others, due to the fulfillment of human needs concerning the contact with nature （green） and living with a sense of intimacy, security and peace. Presented results concern the center of Jarostaw and Laficut. Although both cities are located in an underdeveloped region of south-eastern Poland, they have an opportunity to create a positive image of the city center, where not only attractive architectural objects can be found, but also small-town atmosphere, and natural values forming positive relationships between human and the elements of environment.展开更多
