Wind profile of two sites, one on the southern part of Lesotho, Masitise (-30.367445° latitude, 27.669641° longitude, 1700 m altitude), and the other on the eastern part, Sani (-29.58273° latitude, 29.287845° longitude, 2900 m altitude), was analysed. Wind speed measurements for Masitise are taken at both 10 m and 25 m above ground level (a.g.l.) while for Sani anemometers are only placed at 9 m a.g.l. Both sites fall under the zero roughness class with bi-annual wind speed of 4.93 m/s and 5.50 m/s at 10 m and 9 m a.g.l., respectively. Moreover, their power densities are given by 121.6 W/m2 and 221.3 W/m2. A model using Weibull distribution function is used to analyse the wind speed profile. The results compare well with the Wind Atlas Analysis and Application Program (WAsP). According to the global wind power classification, Masitise is a class 2 site while the windier site of Sani falls under class 3. Masitise may not be ideal for grid-connected electricity production but both sites have sufficient wind for off-grid electricity production. On average the turbines will be generating 80% and 75% of the time per annum at Masitise and Sani, respectively. © 2011 Elsevier Ltd. All rights reserved.

This paper assesses the role of the non-farm sector in rural development in Lesotho. Evidence from studies in developing countries indicates that agriculture was formerly used as the main source of livelihood for many people in poor countries. However, due to the decline in agricultural productivity (which results in poverty and food insecurity) caused by unfavourable agro-climatic conditions, many people are turning to non-farm activities as a means of making a living. Therefore, non-farm incomes are used to provide the means of sustenance for many people. However, little attention has hitherto been paid to improving the rural non-farm sector as an alternative or complementary rural development strategy in Lesotho. This research paper uses quantitative research methods to analyse the available data. The main research findings suggest that many people make a living out of non-farm incomes. As a result, this paper proposes that the rural non-farm sector should be given more priority by the government in rural development in Lesotho. © Cambridge University Press 2016.


This article reports the application of a mixed-solvent ‘bubble-in-drop single drop micro-extraction’ method for pre-concentration of stilbene hormones – hexestrol and diethylstilbestrol from the water sample collected downstream of the cattle slaughterhouse. The optimised conditions for extraction included 75% chloroform–toluene mixture, 2:1 drop–bubble ratio, 10% NaCl, pH 5.5 and 20 min of static extraction. The extraction demonstrated sufficient linearity (R2 ≥ 0.9992), reproducibility and reliability (%RSD < 10%). The enrichment factors between 3218 and 3987 were observed under optimised conditions using the real samples. The observed limit of detection values were in the range of 0.025–0.075 ng/mL using the S/N ratio approach, while the limit of quantification values were in the range of 0.083–0.25 ng/mL. These values are comparable or lower than those reported in the available literature. Application of the method to real samples from the stream did not detect any analytes. These results, however, do not free the slaughterhouse operators from the requirement that they maintain necessary measures to prevent potential pollution of water bodies if these hormones are indeed used, and could still be active in the animal at the time of slaughtering. © 2016 Taylor & Francis

Health systems worldwide are moving toward use of information technology to improve healthcare delivery. However, this requires basic computer skills. This study assessed the computer literacy of nurses in Lesotho using a cross-sectional quantitative approach. A structured questionnaire with 32 standardized computer skills was distributed to 290 randomly selected nurses in Maseru District. Univariate and multivariate logistic regression analyses in Stata 13 were performed to identify factors associated with having inadequate computer skills. Overall, 177 (61%) nurses scored below 16 of the 32 skills assessed. Finding hyperlinks on Web pages (63%), use of advanced search parameters (60.2%), and downloading new software (60.1%) proved to be challenging to the highest proportions of nurses. Age, sex, year of obtaining latest qualification, computer experience, and work experience were significantly (P < .05) associated with inadequate computer skills in univariate analysis. However, in multivariate analyses, sex (P = .001), year of obtaining latest qualification (P = .011), and computer experience (P < .001) emerged as significant factors. The majority of nurses in Lesotho have inadequate computer skills, and this is significantly associated with having many years since obtaining their latest qualification, being female, and lack of exposure to computers. These factors should be considered during planning of training curriculum for nurses in Lesotho. Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved.

Renewable Energy | Year: 2012

Lesotho's energy balance is largely dominated by combustible renewable resources. However, the country is well endowed with hydropower resources for the development of both large and small-scale hydropower projects. There are several challenges that have to be addressed in order to reap the full benefits of this resource. Some of the main challenges are high capital investment costs on projects of this nature and heavy siltation of small reservoirs due to extensive soil erosion.Various studies countrywide have identified 22 sites, with a combined potential of more than 20 MW to be suitable for small hydropower development. Of these sites, 4 have been developed to operational from mid 1980's to early 1990's. The plants were designed as hybrid system with diesel generator sets. Three of those plants operate on a river run-off system.It has been a general practice that the plants run on diesel for most periods of the year, which render them more expensive to run. Currently, 2 of the plants are mothballed as a result of the costs and other operational problems frequently encountered. This paper gives an overview of the setbacks that inhibit the smooth operation of small hydropower plants in Lesotho. © 2012 Elsevier Ltd.

Dye doped polymers (DCPs) has a wide application based on their optical and electrochemical properties. Dye sensitisation of conducting polymeric materials has gained a wide theoretical interest and practical application in sensors and solar cell technology. This review gives a broad summary on synthesis, the effect of the presence of dye in the polymer (properties, structure and conductivity), application in sensors and dye sensitised solar cells. Different sensing modes are also discussed as well as the effects of post polymer modification with dyes in sensors. In solar cells, the role of DCPs in light harvesting is summarised using examples. Finally, perspectives and the advantages of dye modification or sensitisation of polymers in sensors and solar cells are included. © (2010) Trans Tech Publications.

The issue of curriculum relevance has attracted attention of academics and the general public in Lesotho where there are social, economic, environmental and political challenges confronting the society. To address these challenges education, through various school subjects, is expected to play a pivotal role. However, there are concerns that the current Lesotho secondary curriculum does not adequately prepare school leavers for the world of work and further education. This paper takes a reflective approach to debate the potential contribution of secondary school geography to national development goals in Lesotho. It draws on relevant Lesotho national policies to highlight synergies between the national development priorities and the content of secondary school geography. Based on the review of geography syllabus, it is argued that in the light of the current development challenges such as global climate change, natural disasters, increasing levels of unemployment, human trafficking and advancement in technology, geographical understanding is more important than ever before. The paper ends by discussing implications for a geography teacher education programme that would be supportive of a continued survival of geography in the school curriculum. © 2016 Informa UK Limited, trading as Taylor & Francis Group

In the immediate aftermath of Zimbabwe's Economic Structural Adjustment Program (ESAP) experiment, radical changes that completely redefined life in rural areas appear to have taken place. The demise of the worker-peasantry was finally achieved. Using an extended case of worker-peasant communities in north-western Zimbabwe's Lupane District, the article examines the changing dynamics in rural areas. It argues that the world on which the worker-peasantry was premised had crumbled - the relationship between the rural and urban changed while complex processes that had long assured the survival of rural households had completely broken down. This was a new space and time where the fact that certain livelihood practices and relationships no longer applied led to the destruction of old social formations and the creation of new ones, and was certainly not at odds with Tomlinson's proposal for social engineering on the basis of "separate development" through the "betterment" of peasant farming and industry in rural areas, albeit with some modifications. © 2014 SAGE Publications.


In the 1980s and early 1990s, sending remittances from South Africa posed major challenges for Ndebele migrants. As a result households receiving remittances only did so at irregular intervals. With increased diasporisation into South Africa, it was to be expected that new channels would open up. This article explores what is known as the malayisha system, its role and significance as an informal channel of remittances into Ndebele society. It argues that the system bridged the geographical gap between Matabeleland and Johannesburg, averting food insecurity and poverty for semi-proletarian households in Matabeleland. By facilitating the movement of goods and people between Matabeleland and South Africa, the system became instrumental in the quest of households to reconstruct their livelihoods after the destruction of their rural-urban-based livelihoods in Zimbabwe due to perennial droughts and ESAP. As a result, the services of omalayisha are highly sought-after, by both the migrant community in South Africa and households in Matabeleland. © 2011 Cambridge University Press.

The electron distribution for Cl,O bonds in a wide range of molecules is analyzed using Bader's atoms in molecules theory (QTAIM) and measures of bond order. It is shown that the electron density and energy density at the bond critical point correlate very well with bond length, but the Laplacian shows no simple relationship; charge transfer is shown to be responsible for the anomalous behavior. Measures of bond order show a more complex behavior, but a combination of bond order and polarity correlates well with bond length and electron density. The analysis provides several lines of evidence for multiple bonding in the uni-coordinate Cl,O bonds of the molecules. A comparison of a sub-set of results for DFT and CCSD(T) wavefunctions shows their similar behavior. © 2012 Elsevier B.V.
