The urban environment has continued to experience changes from increasing impervious surfaces, which alters the proper functioning of the ecological zones and impairs water quality in the watershed. Impervious cover is predominantly used as an indicator to assist in understanding and forecasting the impact of human actions and other related activities on aquatic resources. In this study, the rate of change in land uses using the impervious surface as an indicator, and the percentage of imperviousness on the effect on water quality in the urban watershed were assessed. Ile-Ife was delineated as an urban watershed, and the percentage of imperviousness from 2008 to 2016 and the effect of imperviousness on water bodies were assessed. The study utilized ASTERDEM, Worldview (0.46 m), IKONOS (1.4 m), Landsat (30 m) for 2008 and 2016, GPS and Drone (10 cm). Water sampling was carried out in selected locations as generated by the impervious surface analyst tool, (ISAT). The percentage (%) of impervious surfaces accounted for 59.4% (4567.1/7691.5ha) in 2008 and 70.3% (5408.2/7691.5ha) in 2016, from the total number of lands investigated. The turbidity values from low to high regions were 32.3, 55.9 and 82.4 NUT. Changes in LULC of the watershed led to increased surface temperature, impermeable surfaces, and decreased vegetation, which exposes the area to flooding and reduced water quality. This study emphasized the importance of GIS and its integration into urban changes and water quality assessment.

Inherent Nature ＆ Dynamics of Political Stability in China

For any society to progress, there must be sensitive leadership that is willing to stir the affairs of the country toward the right direction, the provision of a good life, security, opportunity to exist peacefully, a functioning legal system, responsive government, economic prosperity are all fundamental elements for sta- bility, and progress in any society. With a strong leadership in China, it has grown to become the newest and emerging super economic power bloc of the twenty-first century. Government adoption of philosophies such as the Mandate of Heaven, putting the people first, rule by virtue and deep economic reforms has not only bolstered it＇s authority to rule but has fortified the ruling party position as the only legitimate ruler of the greatest populated country in the world. This article develops a perception that stability of any society can only be achieved when it is deeply rooted in the philosophical ideology of that society and pursuing the core interests of the people. This work sets out to explain and examine the nature of the Chinese Communist Party dynamics in ensuring political stability in China over the decades of its inception into the political stream of the nation state.

Journal of Biomedical Science and Engineering 2017年第8期10卷 402-420页

作者： Nankang G. Lepzem Rachel adetoro Togun Department of Biochemistry Faculty of Medical Sciences University of Jos Jos Nigeria Depatment of Haematology and Immunology Obafemi Awolowo University Ile-Ife Nigeria

Methanolic extracts of Tetracarpidium conophorum (TCME) leaf, seed or leaf + seed extract demonstrated high capacity for reversing hyperglycemia and oxidative stress comparable with the standard anti-diabetic drug, metformin, in alloxan-induced diabetic rats. The leaf + seed extracts showed the best activity among the extracts and also ameliorated oxidative stress-induced damage of pancreas and liver tissue to normal state.
