Physicochemical quality of drinking water in Mubi-North, Girei and Mayo-Belwa local government areas, Adamawa State Northeastern Nigeria was investigated. Water samples were collected using 100ml wide open plastic well sterilized (using distilled water). Sampling was done in the months of August-October for the wet season and January-March for dry season using a portable dissolved oxygen analyzer for DO. Hanna portable pH/EC/TDS/temperature meter for pH, conductivity, total dissolved solids and temperature at sample collection point.

Objective: To describe the complications observed in patients suffering from a limb fracture treated by a traditional method at home before being admitted to hospital. Patients and Method: This was a prospective descriptive study, carried out in the orthopedic-trauma department of the CHU Communautaire of Bangui from January 1 to December 31, 2015. Patients included in the follow-up department had Limb fractures treated by the traditional method and presenting a complication. These patients should indicate their consent and provide information on the traditional treatment received.

Background: The oral- motor dysfunction in cerebral palsy(CP) has a wide base of importance as oropharyngeal dysphagia (OPD) which is a major risk factor for morbidity in this population. It leads to the inability to consume sufficient food and fluids safely and is associated with prolonged mealtimes, poor growth and nutrition and respiratory consequences from oropharyngeal aspiration. Aim: to determine relation between oral motor dysfunction and Gross motor development in children with spastic cerebral palsy.

I began to study the project to overcome the greenhouse effect to combat global climate change since 1996. My research results have been published [1- 4] with the following conclusions:

Plants are frequently exposed to different biotic and a biotic environmental stress factors which exert detrimental effects on plant ecosystems. This study was carried out at the West African Portland Cement Co PLC (Lafarge) in Ogun state and Obajana Cement in Kogi state. A 500 x 500m plot was established in a forest at 50m and 3km distance to the cement factories.

La présente étude examine la relation entre la durée de prise en charge psychosociale et les comportements disciplinaires des ex-enfants en situation de rue. Pour ce faire, 67 ex-enfants (35 filles et 32 garçons) de 09 à 24 ans, en situation de rue et suivi au Centre Enfants de Gloire de Cocody-Abatta ont été enquêtés à partir du questionnaire, de l’entretien et la fiche de suivi individuel. Ainsi, deux (02) groupes de sujets ont été constitués : les pensionnaires ayant bénéficié d’une prise en charge de plus de deux ans et ceux de moins de deux ans.

The potential of bioslurry as a biofertilizer was determined. This was examined by screening bioslurry for the presence of organisms known for their biofertilizer abilities; Congo red yeast extract mannitol agar medium was used for Rhizobium, Waksman medium No 77 (N-free mannitol agar medium) for Azotobacter and Pikoysksya’s broth for Phosphobacteria (Pseudomonas and Bacillus species). The physical and chemical properties of the bioslurry were also analyzed.

Jatropha seed oil was employed in the preparation of different alkyd resin samples using alcoholysis and polycondensation process. The alkyds formation was monitored by determining the acid number of the reaction mixture at time intervals and the extents of the polyesterification reactions were evaluated. Both the Jatropha seed oil and its alkyd resins were characterized by Fourier Transform Infra red (FTIR) spectroscopy. Performance evaluation shows that properties of alkyd resin derived from Malic anhydride are comparable with pthalic anhydride alkyd resins.

Ethyl acetate extract of the Stem bark of Piliostigma reticulatum was tested against clinical bacterial strains including; Escherichia coli, Klebsiella aerogenes, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhi, Streptococcus pyogenes, Staphylococcus aureus, Serratia marscences, Shigella dysenterie and Yersinia enterocolitica using the agar well diffusion method of Perez, (1990). Purified extract were subjected to spectra analysis using NMR and GCMS.Result obtained revealed that the plant extract has antibacterial properties against E. coli, Str. Pyogenes, K.

Study Design: Translation and validity and reliability testing. Objective: To adapt the low back pain rating scale (LBPRS) cross-culturally to Arabic language, investigate the validity, reliability and feasibility of the Arabic version of LBPRS in an Arabic-speaking sample with low back pain. Method: The English version of the LBPRS which had 3 components (back and leg pain, disability index and physical impairement) was translated into Arabic (LBPRS-Ar) and back-translated according to established guidelines.
