Chinhoyi, Zimbabwe

Chinhoyi University of Technology also known as CUT was established by an Act by the Parliament of Zimbabwe on 10 December 2001. The town of Chinhoyi is in Mashonaland West about 120 km from Harare towards Lake Kariba and the Zambian border.The Chinhoyi University of Technology has grown out of the Chinhoyi Technical Teachers’ College that was founded in 1991. The first-degree programmes were offered in 1999 under the control of the University of Zimbabwe. Soon afterwards, in 2001, the institution gained full university status.Today, the university provides undergraduate courses in the fields of agriculture, engineering, and business science. Technical teacher education, and creative art and design, are offered through the university’s single institute, the Institute of Lifelong Learning. With nearly 3 000 students and an academic staff of 163, the university describes itself as ‘a small but highly selective institution’.A Strategic Management postgraduate masters programme was introduced in 2005, and ‘continues to flourish’, a claim that warrants respect when the records show that 62 masters degrees were conferred in 2008, alongside the nearly 700 undergraduate degrees. In addition, a new school is being planned, the School of Hospitality and Tourism, which as part of its academic programme will run a hotel existing on the experimental farm as a commercial venture. The university is there to serve a great purpose to the whole nation. Wikipedia.

Understanding factors influencing large herbivore densities and distribution in terrestrial ecosystems is a fundamental goal of ecology. This study examined environmental factors influencing the density and distribution of wild large herbivores in Gonarezhou National Park, Zimbabwe. Vegetation and surface water were predicted to have a stronger influence than anthropogenic-related disturbances (livestock grazing, fires, settlements and poaching) on the density and distribution of wild large herbivores. Aerial survey data for seven common wild large herbivores conducted in 2007 and 2009 and environmental data were collected. Only grass cover explained a significant proportion of the variation in large herbivore densities and distribution. Moreover, only two species densities significantly differed across the Gonarezhou, namely impala and zebra. In contrast, buffalo, elephant, giraffe, kudu and nyala densities did not differ significantly across the Gonarezhou. Overall, the findings only partly support the study prediction. The study results suggest the need to further investigate the roles of environmental factors at smaller scales in order to tease out their relative strengths in influencing density and distribution of large herbivores. © 2013 John Wiley & Sons Ltd.

The application of diatom indices developed for organically enriched and eutrophic waters in oligotrophic and relatively pristine streams in the Eastern Highlands of Zimbabwe was investigated based on data collected in May-August 2007. Better suitability of diatom indices in investigating the quality of eutrophic, organically enriched waters compared to oligotrophic waters is demonstrated. More robust data sets on taxonomy and autecology of a great number of diatom species are required to make the indices more powerful tools in monitoring water quality and ecological integrity of streams in the region. © 2015 Elsevier Ltd.

This paper retraces: (1) the promulgation of protectionist wildlife policies by colonial administrators at the turn of the 19th Century in Zimbabwe, and their evolutionary trajectory over distinct time periods, (2) the paradigmatic shift and the extent of evolution of wildlife policies with respect to the devolution thrust and local community participation to date. The aim is to re-ignite and keep alive the debate for the improvement of local community livelihoods by meeting their aspirations and addressing poverty. Another section explores the robustness of local community institutional framework following decades of research on their efficacy in the face of internal weaknesses and external pressures. This is discussed in the context of contested devolution and decentralisation concepts which not in the distant past became fashionable rhetoric in the field of local community empowerment in natural resource management. Areas of contests have been explored using a case study approach. Extensive literature consultation and gleaning of 127 published and relevant sources cutting across national, regional and global realms reveal that Zimbabwe and most southern African countries have evolved progressive policies. However, consistent with most literature, the implementation of these otherwise progressive policies remains problematic. Hence, the question, 'when will community-based wildlife conservation initiatives like communal areas management programme for indigenous resources (CAMPFIRE) achieve their initially intended goals of devolution?' remains largely unaddressed. © 2014 Elsevier GmbH.

Reliable knowledge of the spatio-temporal distribution of solar radiation is required for the informed design and deployment planning of solar energy delivery systems. In this paper an improved global solar radiation map for Zimbabwe is developed by merging ground-measured radiation data from a sparsely distributed station network, with less accurate satellite-measured data which have an almost continuous spatial coverage. Monthly clearness index values derived from ground-measured global radiation are correlated with those derived from satellite data to obtain a model for calibrating satellite-measured data at a specified grid interval. Two multiplicative factors are to then used to further correct the generated data; CFm to cater for the in-exactness of the regression fit and the other, IBCF to cater for the interpolation error. Contour maps of global solar radiation are then constructed using interpolation by the geo-statistical method of ordinary kriging. The accuracy of the maps in predicting observed (ground-measured) values was tested by evaluating error statistics; relative bias error (rBE), relative mean bias error (rMBE) and normalized root mean square error (NRMSE) in a "leave-one-out" cross-validation analysis. Results indicate that the maximum normalized root mean square error was 0.028 (about 3%), a significant improvement when compared to an earlier map, the H-G map with a normalized root mean square error (NRMSE) of 0.097. © 2013 Elsevier Ltd.

Solar radiant energy conversion to useful work or electricity is gaining momentum as there are continued efforts towards sustainable energy supplies. The laws of thermodynamics govern the processes of energy transformation to produce work. Exergy represents the maximum work that can be extracted from a system interacting with a specific environment. While there are a number of solar radiation exergy models suggested in literature, there is yet to be a universally accepted one. Solar exergy is sometimes taken to be the global radiation incident to a collector multiplied by the product of transmittance and absorptance. Such proposition ignores the basic principle of exergy as put forward in the Carnot efficiency principle for maximum efficiency of a system. Some formulations apply the temperature of the Sun on the Carnot heat engine efficiency, this ignores the fact that radiation reaching the earth's surface has been diminished, hence the assumption of a Carnot heat engine operating between the Sun's temperature and the environment is imprecise. Other proposed models appear too hypothetical and therefore phyiscally incoherent. The lack of a common exergy model leads to inconsistence when it comes to exergetic appraisal of energy systems.This paper is an effort to present a model that attempts to apply simple thermodynamic principles in coming up with what can be considered more realistic. Terrestrial radiation exchange with a blackbody receiver coupled to a Carnot heat engine is hereby proposed. From the present theoretical analysis, it is noted that the obtained exergy values are within the expected order of magnitudes. The proposed model compare closely with Petela's model if in Petela's model the characteristic or effective temperature of the incident radiation is applied instead of the Sun's temperature. Maximum exergy efficiency of 87.64% from a correlation obtained through curve fitting compares well with 86.8% reported as the maximum photoelectric solar energy conversion. Source
