Sugar Content, pH, and Weight of Four Germplasms of Cashew Apple (Anacardium occidentale Linn.) Fruits Grown Under Two Agro-Ecological Zones in Ghana

Changes in climatic conditions are associated with changes in the physicochemical properties of many fruits. Four germplasms of cashew apple originating from Brazil, Tanzania, Ghana (herein referred to as local) and Mozambique but all grown in Ghana were studied to assess the effect of agro-climatic zones on the sugar accumulation, pH, and weight of these cashew apples. Cashew apples were sourced from experimental stations in Bole and Wenchi in the Northern and Savannah regions of Ghana, respectively. A total of 1800 fruits were used for the experiment. Inter and intra significant differences (P < 0.05) were scored amongst ger­mplasms collected from both locations concerning the measured parameters. Sugar ranged between 8.7% - 12.5% with fruits from Bole having the highest sugar content. The pH value ranged from 3.9 (Local germplasm from Bole) – 4.3 (Tanzania germplasm from both loca­tions). The weight ranged between 33 g (Tanzania germplasm from Bole) – 69.8 g (Brazil germplasm from Bole). Meteorological data (from February 2017- April 2018) collected from both locations inf‍luenced the parameters, thus associating with the fruits from both locations. Conclusively, the present study indicated that, weather and geographical locations had an effect on sugar content, pH, and weight of cashew apples

A psychrometric analysis of thermal comfort In low-rise office buildings in Ghana

A research project on the thermal performance of office buildings in Ghana was conducted and in the process, data loggers were used to record indoor environmental conditions over a period of 12 months in five office buildings. The temperature and relative humidity values recorded were analysed and plotted on psychrometric charts. The results of the study in 15 offices wereplaced in psychrometric charts which showed uncomfortable indoor environmental conditions. The reasons were high relative humidity values, although the temperatures in most of the cases were below 29°C. The impression gained during the observation period was that occupants hadadapted to high humidity levels and therefore found maximum humidity levels of 80% comfortable, provided temperature values did not exceed 29°C. This significant clue calls for further study and the adjustment of the comfort scale for the climatic context of Kumasi, Ghana

Effects of tillage and cropping systems on yield and nitrogen fixation of cowpea intercropped with maize in northern Guinea savanna zone of Ghana

Published information is scanty on the response of crops in mixed cropping systems to the various tillage systems practised by farmers in the northern savanna zone of Ghana. A field experiment assessed the yield and nitrogen (N) fixation of cowpea (Vigna unguiculata (L.) Walp) intercropped with maize (Zea mays L.) on four different tillage systems at Nyankpala in the Northern Region of Ghana. The experiment was laid in a split-plot design with four replications. The main factor was tillage systems comprising conventional (Con), bullock plough (BP), hand hoe (HH) and zero tillage (ZT). The sub-factor was cropping systems (CRPSYT) which consisted of sole maize, sole cowpea, maize/cowpea inter-row cropping system, and bare fallow in 2000. The last-named was replaced by maize/cowpea intra-row cropping system in 2001. The results showed that Con and BP, which produced over 10 cm plough depth, significantly reduced soil bulk density that favoured significant (

Determining matrimonial property rights on divorce : an appraisal of the legal regimes in Botswana

The bulk of the matrimonial property regimes operating in Botswana were inherited from the country's colonial past. Since independence there ha'> not been any realistic attempt to reform them. The thesis set out to appraisal the legal regimes governing the determination of matrimonial property on divorce to ascertain their efficacy in realising the legitimate aspiration of married couples. Comparisons were made with similar countries to determine how these have tackled problems relating to determination of matrimonial property on divorce. The study found that where there is a dispute about matrimonial property in marriages out of community, the courts have no discretion to readjust the rights of the parties. This situation adversely affect nonworking wives who spent most of their time looking after their husbands and children without being able to acquire capital assets. Recognition is not given to such domestic contribution to the welfare of the family. It was also found that the exercise of the marital power by husbands of marriages in community of property deprives wives of those marriages the right to administer the joint estate. The patriarchal nature of customary law, which governs the majority of disputes about matrimonial property, discriminates against women. Consequently, the following, inter alia, are suggested as reform measures. (a) The courts should be g1ven a wide discretionary power, circumscribed by statutory guidelines, to reallocate matrimonial property on divorce irrespective of the matrimonial property regime that governs the marriage. TI1e underlying principle should be equality of sharing but this may be departed from where the circumstances of the particular case warrant it (b) A spouse's domestic contribution towards the welfare of the family should be recognised. (c) The marital power of husbands should be abolished. (d) The provisions of the Matrimonial Causes Act should be made applicable to customary marriages.Private LawLL.D

Carbon dioxide fluxes from contrasting ecosystems in the Sudanian Savanna in West Africa

Background: The terrestrial land surface in West Africa is made up of several types of savanna ecosystems differing in land use changes which modulate gas exchanges between their vegetation and the overlying atmosphere. This study compares diurnal and seasonal estimates of CO2 fluxes from three contrasting ecosystems, a grassland, a mixture of fallow and cropland, and nature reserve in the Sudanian Savanna and relate them to water availability and land use characteristics. Results: Over the study period, and for the three study sites, low soil moisture availability, high vapour pressure deficit and low ecosystem respiration were prevalent during the dry season (November to March), but the contrary occurred during the rainy season (May to October). Carbon uptake predominantly took place in the rainy season, while net carbon efflux occurred in the dry season as well as the dry to wet and wet to dry transition periods (AM and ND) respectively. Carbon uptake decreased in the order of the nature reserve, a mixture of fallow and cropland, and grassland. Only the nature reserve ecosystem at the Nazinga Park served as a net sink of CO2, mostly by virtue of a several times larger carbon uptake and ecosystem water use efficiency during the rainy season than at the other sites. These differences were influenced by albedo, LAI, EWUE, PPFD and climatology during the period of study. Conclusion: These results suggest that land use characteristics affect plant physiological processes that lead to flux exchanges over the Sudanian Savanna ecosystems. It affects the diurnal, seasonal and annual changes in NEE and its composite signals, GPP and RE. GPP and NEE were generally related as NEE scaled with photosynthesis with higher CO2 assimilation leading to higher GPP. However, CO2 effluxes over the study period suggest that besides biomass regrowth, other processes, most likely from the soil might have also contributed to the enhancement of ecosystem respiration. © 2015 Quansah et al

Is team sport the key to getting everybody active, every day? A systematic review of physical activity interventions aimed at increasing girls' participation in team sport

Background: It is estimated that 21% of boys and 16% of girls in England meet recommended physical activity guidelines. Team sport has the potential to increase physical activity levels; however, studies show that gender-based factors can influence girls’ participation in team sport. Furthermore, evidence for the effectiveness of interventions promoting team sport among girls is limited. This systematic review aimed to assess the impact of physical activity interventions on secondary school-aged girls’ (aged 11-18 years) participation in team sport and to identify potential strategies for increasing participation. Methods: Electronic databases and grey literature were systematically searched for studies of interventions targeting team sport participation among girls in the UK. Results were exported to Refworks, duplicates removed and eligible studies identified. Extracted data included: participant details, such as sample size and age; components of the intervention; outcomes assessed; and each study was quality appraised. Due to heterogeneity across studies, results were presented narratively. Results: Four studies sourced from the grey literature met the inclusion criteria. Findings suggest that physical activity interventions can encourage girls to try new sports, but evidence is limited in relation to sustained participation. Potential strategies for promoting participation included: consultation with girls, implementation of appropriate peer-leaders and friendship group strategies, early intervention and consideration of intervention setting. Conclusions: This review highlights the limited availability of evidence on the effectiveness of physical activity interventions for promoting team sport participation among girls in the UK. Findings indicate that future research is needed to improve the methodological quality of complex intervention evaluation. Physical activity interventions may have the potential to encourage girls to try team sport, but their impact on sustained participation, and subsequent physical activity outcomes, is less apparent
