SOME ASPECTS OF THE BIOLOGY OF Macrobrachium dux (LENZ, 1910) (CRUSTACEA:DECAPODA:NATANTIA) IN RIVER OROGODO, NIGER DELTA, NIGERIA Acta biol.Colomb.
ARIMORO,FRANCIS O; MEYE,JACOB A.
Preliminary investigation into some aspects of the biology of the palaemonid prawn, Macrobrachium dux (Lenz, 1910) in River Orogodo at Abavo, southern Nigeria was carried out between March and August 1995. The freshwater prawns were collected with properly baited cage traps and scooping with hand basket. The study revealed that the prawn species were widespread and abundant in the river. Abundance in terms of number and biomass was more during the wet season with a peak in August. Both adults and juveniles showed a progressive increase from late dry season to midrainy season (August). The malefemale ratio was 1:1.2. The fluctuation in the number and percentage of ovigerous females indicated that the prawn spawned during the midrainy season (JuneAugust)....

Cocoa Pod Ash as Bio-Based Catalyst for Biodiesel Production from Waste Chicken Fat CIGR Journal
Odetoye, Temitope Elizabeth; Amusan, Greatness S..
The growing interest in using sustainable raw materials coupled with the need to reduce the over- dependence on non-renewable petroleum resources has made agricultural residues attractive raw material for biofuel production. The potential utilization of cocoa pod ash (CPA) as a bio-based catalyst for the production of biodiesel from waste chicken fat was investigated. Bio-based catalyst was obtained from cocoa pods by ashing method. The catalyst was subjected to scanning electron microscope (SEM) analysis. The experimental design was based on a five level, two factor central composite design. CPA was used in the preparation of biodiesel from waste chicken fat (WCF) using a two-step esterification-transesterification process. The highest biodiesel yield of...

Effect of frying conditions on storage stability of fried maize snack (kokoro) CIGR Journal
Akinoso, Rahman; Akinoso, Rahman.
Snacks can be produced from maize and other cereals and legumes. Kokoro is a popular traditional fried maize snack widely consumed among adults and children in South Western states of Nigeria. Short shelf life is associated with fried products including kokoro. Improving its shelf life therefore entails understanding the frying process, optimizing the frying condition and studying the storage stability of the fried product. This work was designed to study the storage stability of kokoro (produced at the recommended optimum processing condition) enriched with African yam bean (AYB) and evaluate its storage life. The kokoro was produced and packaged in polyethylene bags (100μm) and stored at ambient conditions (24°C±3°C temperature and 61%±3% relative...

UPFLOW model prediction of capillary rise into root zone soil moisture for shallow water table soils of Obio Akpa river floodplain in the Niger-Delta environment, Nigeria. CIGR Journal
Udom, Ikpe Jimmy; Nta, Samuel Akpan.
UPFLOW model was used to provide assessments of capillary rise into root zone soil moisture in shallow water table soils of Obio Akpa river floodplain using drum-culture lysimeters. Soil moisture depletion experiment was undertaken through the use of drums with bases intact and drums with bases removed and sunk in the field at different depths during the dry period with no rainfall and no irrigation. UPFLOW model was validated by comparing simulated capillary soil moisture values from a falling water table with gravimetrically observed data from 0 – 500, 500-1000 and, 1000-1500 mm water table  depth in sandy loam and sandy clay soils. Simulated runs mimic the observed fluctuations and trend of capillary rise to the root zone. The statistical pointers of...

Assessing the Impact of Changing Climate on Crop Water Requirements in Nigeria. CIGR Journal
Ilesanmi, Oluwaseun Ayodele.
Climate change is a phenomenon most of the world is recently coming to terms with but unfortunately, the African region is yet to fully understand and prepare for its effects. The change is predicted to herald positive results likewise potentially severe consequences for global food security. This study aims to improve the understanding of the impact these changes being experienced in the Nigerian climate system will have on Crop Water Requirements (CWR) for optimal productivity. Five statistically downscaled and bias-corrected Global Climate Models (GCMs): CCCMA, NOAA, MIROC, ICHEC, and NCC were applied in the estimation of CWR through the period 1985–2100 under the Representative Concentration Pathway RCP8.5. These were used to produce values of crop...

Seroprevalence of HIV among blood donors, antenatal women and other patients in a tertiary hospital in Nigeria BJID
Olajubu,F. A.; Osinupebi,O. A.; Deji-Agboola,M.; Jagun,E.O..
HIV/AIDS continues to remain a nightmare in the developing nations of the world especially in Nigeria, where about 2.9 million people are living with this problem. This study aimed at determining the sero-prevalence of HIV among both patients and blood donors at the Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria. Samples were collected between January 1st, 2005 and December, 31st 2006 and were screened using two rapid test kits, with two different principles (enzymatic and agglutination). Samples positive to the two methods were taken as truly sero-positive. The seropositive rate among blood donors, antenatal women, in- and out patients were, 3.2%, 6.9% and 17.5% respectively. There were five cases of positivity to both HIV I and II....

A review of the epidemiology, prevention and treatment of human immunodeficiency virus infection in Nigeria BJID
Entonu,P.E.; Agwale,S.M..
In order to amalgamate research findings on HIV/AIDS in Nigeria as well as the trend of the infection in a concise manner, we reviewed published articles on the HIV/AIDS situation in Nigeria. We categorized this review into several subheadings. The HIV prevalence rate has continued to rise steadily from less than 0.1% in 1987, to 5.8% in 2001, with a slight decrease in 2003 to 5.0%. Although the knowledge about HIV and its mode of transmission is widespread, it is however disheartening to note that this did not result into appreciable attitudinal change and behavior modification among Nigerians. Both HIV-1 and HIV-2 have been identified in Nigeria, with HIV-1 being the predominant type. Furthermore, several subtypes like subtypes A, B, C, G and J have been...

Seroprevalence of chikungunya virus infection in five hospitals within Anyigba, Kogi State of Nigeria BJID
Omatola,Cornelius A.; Onoja,Bernard A.; Fassan,Peter K.; Osaruyi,Stephanie A.; Iyeh,Mercy; Samuel,Matthew A.; Haruna,Peace U..
ABSTRACT Febrile illnesses in developing countries are often misdiagnosed as malaria or typhoid fever. Although arboviral infections have similar clinical symptoms, they are usually not screened because of limited resources and the fact that there are several viruses in this group. Chikungunya virus (CHIKV) has been isolated in parts of Nigeria, but there is no documented evidence of the infection in Kogi State. This study determined seroprevalence of active and past CHIKV infection among febrile patients who tested negative for malaria and typhoid fever. Sera from 243 febrile patients were screened for CHIKV IgG and IgM using an immunochromatographic test kit. Clinical and socio-demographic variables were collected using a structured questionnaire. Recent...

A peridomestic population of the tsetse fly Glossina palpalis palpalis Robineau-Desvoidy, 1830 (Diptera: Glossinidae) at Kontagora town, Niger state, Nigeria Entomología
Ahmed,A. B..
The present article considers some aspects of a peridomestic population of the tsetse fly Glossina palpalis palpalis Robineau-Desvoidy, 1830 in Kontagora, Nigeria. This situation characterizes an abnormal behaviour of the vector, and it is of significant epidemiological importance. Data on the ecology of this species were collected in 1995 and 1999. The results indicated that the species exists during both dry and wet seasons; approximately 30.0% of the catches were gorged with blood giving a MHS of 2.4, indicating a well-nourished population. Dissection of inseminated pars indicated pregnancy rates of approximately 30.0% and 70.0% in the dry and wet seasons and the presence of all 4 stages of pregnancy, suggesting that breeding occurs at both seasons....

Association Between Tongue Rolling and Tongue Folding in Osogbo, Southwestern Nigeria International Journal of Morphology
Igbeneghu,Christopher; Olukanni,Folake; Olisekodiaka,Japhet; Adesina,Adekunle.
This study was carried out among 144 individuals (18 years) from the Yoruba tribe of Southwestern Nigeria in order to determine the association between tongue rolling and folding. Participants were examined for the ability to roll and/or fold their tongues. The incidence of tongue rollers and folders were 59.7 % and 79.2 % respectively. Tongue rolling was higher in females than male but the difference was not significant (X2= 1.039, df = 1, p= 0.308). Tongue folding was significantly higher in females than males (X2= 4.211, df= 1, p= 0.04). Of the 144 participants, 76 (52.8 %) were tongue rollers and folders, 10 (6.9 %) were rollers and non-folders, 38 (26.4 %) were non-rollers and folders and 20 (13.9 %) were non-rollers and non-folders.

Morphometric Differentiation of Two Nigerian Fish Species (Oreochromis niloticus and Lates niloticus) Using Principal Components and Discriminant Analysis International Journal of Morphology
Yakubu,A; Okunsebor,S. A.
Morphological differences between two close fish populations were investigated in Doma Dam, north central Nigeria using principal component and discriminant analyses. The purpose was to identify the two species correctly and assign them into distinct genetic groups. To achieve this, seven morphometric measurements (body weight, standard length, total length, head length, body depth, dorsal fin length and caudal fin length) were made on each of the studied 252 fish specimens (153 Oreochromis niloticus and 99 Lates niloticus). The analysis of variance showed that significantly (P<0.05) higher values were recorded for Lates niloticus in all the body traits examined, except dorsal fin length. From the principal component analysis, the differences between...

Unilateral Cryptorchidism in Nigerian Sahel Bucks International Journal of Morphology
Igbokwe,I. O; Grema,H. A; Ikpo,A. E; Mshelbwala,F. M; Igbokwe,N. A.
Out of 1608 Nigerian Sahel male goats (bucks) examined for cryptorchidism in an abattoir, 9 (0.6%) had right unilateral cryptorchidism. The coat colour-specific prevalence was highest among the brown bucks (2.1%); and was 0.8%, 0.6%, and 0.3% among black, white, back-and-white bucks, respectively. The condition was not found among bucks with brown-and-black, brown-and-white, and multiple coat colours. The right and left testes of normal bucks and the descended testes of cryptorchid bucks had comparable gross testicular measurements, but the retained cryptorchid testes were smaller in size. The estimates of the testicular measurements showed that testicular weights (with the entire epididymes), peripheral longitudinal lengths and mid-circumferences of the...

Craniofacial Anthropometry in a Young Nigerian Population: the Canthal Distances International Journal of Morphology
Jaja,Blessing N.R; Fawehinmi,Hakeem B; Jack,Joy T.
The measurement of craniofacial parameters have clinical, forensic and anthropologic significance. Local data on inner canthal and outer canthal distances and the canthal index may reveal the pattern of differential growth in craniofacial features resulting from factors such as sex, diet and genetic distinctions. In the present study, we provide normative data on canthal distances in a Nigerian population which has not been studied previously, utilizing a study design which optimises the effect of age and minimise bias and confounding than previous studies in Nigerian groups. The mean inner canthal distance was 1.85±0.30cm and 2.07±0.29cm (males vs. females, p= 0.000); mean outer canthal distance, 10.39±0.56cm and 10.40±0.98cm (males vs. female, p= 0.899)....
