In inflammation, the distance from blood vessel to mucosa is reduced in all five regions of the middle ear cleft. This distance is statistically the shortest in the postero-superior compartment of the middle ear cleft.
The purpose of the study was to quantify waste content in faecal sludge using an appropriate method and characterise the solid wastes inherent with the faecal sludge into categories. A total of eight (8) domestic pit-latrines were analysed in the peri-urban area of Kanyama settlement in Lusaka from July to October, 2018. From each latrine, three (3) samples were obtained for analysis of solid waste and sand/grit quantities. The quantified solid waste was further characterised to generate its composition. The method of estimation involved separation of the excreta from the solid waste and grit/sand of the faecal sludge by means of washing and drying of the contents. The results indicated high content of total waste, taken as the summation of all the solid waste including grit/sand which averaged 34.2±10.3% (n=24) per wet mass of faecal sludge and 68.9±8.0% (n=24) per dry mass of faecal sludge. Characterisation of the solid waste in the faecal sludge (n=24) showed a composition of 54.4±13.3% textiles, 16.7±6.4% plastics, 8.6±9.3% others, 8.6±5.8% organic waste, 7.6±4.8% paper, 3.1±3.6% metal and 1.0±1.2% glass. The high content of waste has an implication on the handling of faecal sludge especially at the stages of desludging, treatment and disposal/re-use. The study proposed and recommended implementation of user education, improving solid waste management systems in periurban areas and studying the feasibility of placing some facilities like biogas digesters above ground to facilitate removal of grit, which is usually problematic with underground facilities. The study also proposed and recommended strengthening the regulation on the construction and operations of latrines, which should be supported by enacting a responsive regulatory framework to ensure all measures, are effectively implemented.
Mount Elgon forest is a trans-boundary ecosystem transcending Kenya-Uganda border. It is an important watershed which nourishes Lake Victoria, Lake Kyoga, Lake Turkana and a vast array of rivers including the Nile. The Benet/Ndorobo community has for a long time been using the forest as a shelter, source of pasture for livestock and wild food as well as products like handcrafts materials. In the recent past, the community has adopted crop farming with adverse effect on the forest ecosystem. To avert the dire consequences of forest degradation as a result of human settlement, the government decided to degazette about 6000 ha of the forest to systematically resettle this group. However, the resettlement exercise was mismanaged and as a result, many people were either not properly resettled or totally ignored. Further attempts by the government to portion more forest land for Benet/Ndorobos was in vain. Against this background, a study was carried out between August 2014 and June 2015 aimed at identifying the governance issues involved in the management of the forest and root causes of the resettlement problems, leading to
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
