Changes in microbial and soil organic matter following amendment with olive mill wastewaters
In this work, the occurrence of the untreated and treated olive mill wastewaters (OMW) amendment on the soil organic matter recycling and on its microbial biomass evolution were investigated. Compared to the control, soils amended with untreated and treated OMW showed high levels of organic and mineral matters. Soil amended with untreated OMW presents low levels of total and inorganic nitrogen (0.38 ± 0.03 and...

Mixed contaminant interactions in soil: Implications for bioavailability, risk assessment and remediation
Majority of contaminated sites in the world contain complex mixtures of heavy metals and organic contaminants from diverse natural processes and anthropogenic activities. Mixed interactions of heavy metals and organic contaminants may affect their bioavailability and accumulation in soil and biota through synergistic or antagonistic processes. Evaluation of contaminant bioavailability is a necessary component of the...

Adequacy of ventilation systems: An explorative study of the perspectives of designers and occupants of high rise buildings in Nairobi, Kenya
Passive ventilation systems have the potential for reduced operating costs in office buildings while maintaining ventilation rates consistent with acceptable indoor air quality. There is a surge of interest in more developed economies for passive ventilation technology but much work is needed before this potential can be realized in sub-Saharan Africa. This explorative study reviews the adoption and adequacy of...

Variation of small scale wetland fishery in relation to land use along Mpologoma riverine marsh in Eastern Uganda
In densely populated areas such as those in eastern Uganda where livelihoods demands create immense pressure on environmental resources, small scale wetland fisheries may be disturbed by agriculture practices. The study carried out between 2011 and 2012, investigated the variation of fish catch at the different wetland sites in relation to land use in Mpologoma riverine marsh. Four sites were identified to represent...

Seasonal physico-chemical and microbiological pollutants of potable groundwater in Qena governorate, Egypt: A case study
In 9 districts of Qena governorate, Egypt, groundwater is used for human consumption. This study was carried out to evaluate the quality of these water sources. In each district, 2 wells were sampled in different seasons and physico-chemical and microbiological parameters were determined and compared with the Egyptian standards. All the tested wells had problems in physico-chemical or microbiological parameters or both....

Perspective of young drivers towards the care of the road traffic injured
The existing structure of pre-hospital trauma care in developing countries is largely deficient. The goal of this study was to determine the knowledge and attitude of young drivers towards the care of the road traffic injured. This was a descriptive cross sectional study which we carried out among undergraduates of the Ladoke Akintola University of Technology Campus, Ogbomosho, Oyo state, Nigeria using a stratified...
