PurposeThe disposal of solid waste is a serious environmental problem for humanity. Vermicomposting is used as one of the methods for recycling of organic waste, resulting in a humified material of great agronomic potential which promotes carbon sequestration when applied to the soil. The aim of this study was to evaluate the chemical characteristics of vermicomposts from cattle manure (CM), orange peel (OP) and filter cake (FC).
Three compost piles were set up, 2:1 OP + CM, 3:1 FC + CM and CM. The piles were initially composted for 60 days. Thereafter, earthworms were added to the piles to initiate the vermicomposting process.
The pH and the organic carbon contents were above the minimum recommended values for organic fertilizers. The N content was below the minimum value but the C/N ratio was in the required range. The C/N values where lower in OP + CM and FC + CM than in CM. Further, the N contents of treatments were different with OP + CM having the highest value. The C/N ratios of the piles were 9.52, 9.62 and 11.03 for OP + CM, FC + CM and CM, respectively, and were lower than the maximum recommended value by the Ministry of Agriculture, Livestock and Food (Ministry of Agriculture 2009).
Thus, co-vermicomposting of filter cake and orange peel with cattle manure has the potential for application sustainable agriculture.

Babalola, O, Adesanya D.  2008.  An appraisal of the factors affecting production of cost estimate for electrical services in Nigeria, 2008/07/25. 13:200-208. Abstract

PurposeElectrical services contribute a substantial percentage of total construction cost of any particular project. It is essential for estimators to have a detailed knowledge of the factors that affect the incorporation of electrical services cost into the overall building project cost. The overall aim of the study that formed the basis for this paper therefore was to investigate the factors that influence cost estimating of electrical services project.
The study was carried out based on questionnaire survey of 225 organizations that are involved in cost estimating of electrical services projects in Nigeria. A total of 158 questionnaires out of the 163 retrieved were appropriate for analysis. A list of factors potentially influencing cost estimate for electrical services was identified for the respondents to rate. The data collected were analyzed using factor analysis based on principal component analysis and varimax orthogonal rotation.
The results shows that the factors affecting production of cost estimate for electrical services could be grouped into four principal factors: the most important factor grouping being estimator competence followed by project technicality, economic requirements and contract requirements.
Practical implications
Many factors are considered by practitioners in the preparation of cost estimate for electrical work in construction project development. The paper has listed about 23 factors that are relevant. However, this paper has shown that four principal factors need to be considered as they explain 64 percent of the factors affect cost estimate production for building project's electrical service works.
Review of literature has shown that there is limited empirical research on the factors influencing cost estimate production for electrical services work. The paper has produced an empirical research on the crucial factors that must be taken into account when producing cost estimate for the electrical service projects.

Babatimehin, O, Nelson N-T, Oyinloye R, Adeoye N, Taiwo O, Daniel J.  2015.  Send Orders for Reprints to Geographical Analysis of the Patterns of Healthcare Facilities and HIV/ AIDS Response Sites in Benue State, Nigeria, 2015/01/01. 7:17-27. Abstract

This study analysed the spatial patterns and characteristics of healthcare facilities and HIV/AIDS response sites; and the relationship between the distribution of population and healthcare facilities/HIV/AIDS response sites in Benue State, the State with the highest record of HIV/AIDS in Nigeria. Primary and secondary data were used for the study. GPS receiver was used to obtain the geographic coordinates of healthcare facilities and HIV/AIDS response sites; and questionnaire to acquire attribute data of the sites. The secondary data used included the list of all healthcare facilities at community and LGA levels, maps, and the population of the state. The spatial analyses of the phenomena of interest were done based on the LGAs. All the 1243 healthcare facilities in the 23 LGAs of the state were captured in the study. Four key HIV/AIDS services (VCT, PMTCT, ART and HBC) were purposively selected for the study. The analogue map of Benue State was processed and used for various GIS analyses and cartographic enhancement for the purpose of report presentation. The study identified three categories of Healthcare Facilities (primary, secondary and tertiary) in the state. There existed spatial variation in the distribution of the various healthcare facilities in the state. The PHCs were observed to be more widely distributed in the state (93.4%) than the SHCs (6.3%) and THCs (0.2%) which were observed to be largely concentrated in the urban LGAs. Also, specialised HIV/AIDS services like PMTCT and ART were observed to be concentrated in the urban LGAs. The population/Facility ratio for PHCF, SHCF and THCF were 2,371:1; 34,413:1; and 1,376,539:1 respectively. There existed a direct relationship between both population and distribution of healthcare facilities (r = 0.694, p > 0.5); and population and the distribution of HIV/AIDS response sites (r = 0.664, p > 0.5) in the state. The study concluded that the problem of HIV/AIDS in Benue State is more engendered by the paucity of information about the availability of response sites than their inadequacy; and recommends that a robust database for healthcare facilities and HIV/AIDS response sites be developed at all levels in order to enhance information flow to policy formulators and by extension people who require healthcare and HIV/AIDS services.
