- Description: Background. There is a dearth of information on the relationship between indoor air pollution and lung function, especially among sub-Saharan African children. Objective. To assess the relationship between indoor particulate matter (PM) and lung function in children living in the Eastern Cape Province of South Africa (SA). Methods. This cross-sectional study included 540 children aged 10 - 14 years and was conducted between May and September 2016. PM from 23 classrooms was measured with a handheld particle counter and lung function was assessed with a handheld spirometer. Results. Mean (standard deviation) PM5 levels were higher (109.96 (75.39) μg/m3 ) than PM10 (84.84 (63.28) μg/m3 ) and PM2.5 (39.45 (26.38) μg/m3 ). PM2.5, PM5 and PM10 correlated negatively…

- Description: Renewable Energy Independent Power Producer Procurement launched in 2011 contracts renewable energy producers to supplement the national electricity grid. No preferred bidders produce energy using hydrogen fuel cells, particularly Proton Exchange Membrane Fuel Cell (PEMFC), possibly due to technicalities associated with qualifying hydrogen and fuel cells as renewable. The study explores processes to be followed in South Africa to commercialize green hydrogen production for PEMFC from kraal manure. The paper employed an integrative literature review methodology. There are different stages in product commercialisation, such as developing a product, taking the product to markets, growth, and diffusion. The discussions indicate a huge amount of hydrogen that can be produced from kraal manure that is in abundance in the Eastern Cape. Commercialization of hydrogen production can address global economic goals such as waste management, fighting poverty, reducing unemployment and addressing energy challenges.
