Maseno University is a university based in Maseno, near Kisumu, in Kenya and was founded in 1991. It is one of the seven public universities in Kenya. Currently,Maseno University is ranked as the second best university in Kenya.It has over ten thousand students pursuing various programs offered in the University's campuses.The university is in Maseno Township along Kisumu-Busia road, some 25 km from Kisumu City and 400 km west of Nairobi. It has two campuses: the Kisumu and the main campus. The main campus is along Kisumu-Busia road, while the Kisumu campus is located in Kisumu City.The name "Maseno" was coined by Rev. J.J. Willis out of the name of a tree known in local dialects as "Oseno" or "Oluseno" that stood next to the spot where the first missionaries in the region erected their base. Wikipedia.

Periodic river floods have devastating social and economic impacts on poor households in the low-lying coastal and western regions of Kenya. This paper focuses on how households in Bunyala District coped with the impacts of flooding, and particularly the December 2011 River Nzoia flood. The data for the study was collected through a survey of 400 households, three focus group discussions, four in-depth interviews and six key informant interviews. Of the surveyed household-heads, 393 (98.4%) reported negative impacts of the flood on farming, livestock and/or property. Coping strategies at household level included temporary relocation and migration, reduced expenditure on household needs, engagement in extra income-generating activities, selling of property and reliance on support from public and private agencies. The findings reveal that many of the coping measures that people use are erosive, as they have negative long-term effects on household livelihood sustainability.

Renewable and Sustainable Energy Reviews

A solar chimney power plant (SCPP) is proposed to be built in Qinghai-Tibet Plateau where there is abundant solar radiation, high direct solar radiation low atmospheric temperature, large diurnal temperature range, and lots of salt lakes working as heat storage system, which can help to improve the power output of SCPP. The plant is expected to power local railway traffic lines and act as a solar power base to supply power for national development. The performance of the SCPP that will be built in Qinghai-Tibet Plateau is analyzed and power potential estimated by developing a simple mathematical model. It is found that SCPP if built in the plateau can produce twice more power than an SCPP built on the same latitude of other regions. The yearly power potential for SCPP in Qinghai-Tibet Plateau is estimated to be 86.8 million TJ. When 10-20% of the plateau land is used for the SCPP, the yearly power output may reach 8.7 million TJ to 17.4 million TJ, accounting for 10.7-21.3% of China's energy consumption in 2008 which stood at 81.6 million TJ. It is found that the SCPP in the plateau can support local and national development together with other renewable energy resources such as hydroelectric power and wind power. © 2010 Elsevier Ltd.

This study evaluates the link between the occurrence of El Nino events in East Africa and water hyacinth blooms in Winam Gulf of Lake Victoria using remote sensing technology. A time-series of the Normalized Difference Vegetation Index (NDVI) analyzed from data acquired by the multispectral Aqua/Terra sensors aboard the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite are used to monitor areal extent and density of the aquatic plants. We related the NDVI derived from MODIS imagery to data on El Niño South Oscillation (ENSO) events that were obtained from NOAA and rainfall data from the study site. Our results from the 11-year time-series data show a statistically significant positive correlation (R = 0.6, P = 0.021) between the occurrence of El Niño events and water hyacinth blooms in Winam Gulf. The proliferation of water hyacinth rafts in Winam Gulf may be a response to dramatic environmental and water quality changes in Lake Victoria. The patterns of impact of ENSO events and rainfall show spatial and temporal variation patterns in the region, depending on the time and space evolution of each individual ENSO event that could explain the differences in general patterns of water hyacinth cover in Lake Victoria during different El Niño events. Although the problems eutrophication and water hyacinth are severe in the Winam Gulf of Lake Victoria some of the solutions to the problem are located several hundreds of kilometers away in the rich agricultural farmlands of the Lake Victoria catchment area. These include better land management practices and strategies aimed at limiting pollution and soil erosion within the lake's drainage basin. © 2011 Springer Science+Business Media B.V. Source

Pyrazolyl ligands have been used to prepare metal complexes since the mid-1960s as nitrogen-donor ligands. However, unlike other nitrogen-donor ligands like imines and pyridines, their metal complexes have not been used extensively in catalysis. This review highlights the emergence of pyrazolyl metal complexes as nitrogen-donor catalysts, particularly in carbon-carbon coupling reactions. The focus is on olefin oligomerization and polymerization, acetylene oligomerization and polymerization, Heck and Suzuki coupling and ring opening polymerization of cyclic monomers. It highlights successes and problems of these catalysts, but draws attention to this burgeoning area so that other researchers can take advantage of these remarkable ligands. © 2010 Elsevier B.V.

This paper presents a matrix method approach to modeling of energy usage and financial planning for households, industries, institutions and communities. A discussion is then presented on how the model can be modified and implemented for national or global use. © Nova Science Publishers, Inc. Source
