Title : Physical Properties of Wall Clads Produced From Mixture of Saw Dust and Pure Water Sachet
Authors : Akinfiresoye W. Ayo, Olarewaju O. Opeyemi, Adebayo S. Ayodeji
Abstract :
(16.5 x 36.5 x 145.5) mm clads were produced from the mixture of sawdust (SD) of three indigenous wood species(Miliciaexelsa, Ceibapetandraand Cola gigantia) and nylon sachet (NS) of “pure water”. From each of the wood specie, clads were produced at three different SD/NS ratios of 40:60, 30:70 and 20:80. The effect of the wood species and mix ratio on the physical properties (water absorption, thickness swelling and linear expansion) of the clads were investigated by immersing them inside water of temperature 20oC for 24 hours. NS was washed, dried, weighed as appropriate and allowed to melt at 190oC in the melting chamber of an existing locally produced Wood Plastic CompositeExtruder (WPCE)of 0.8 kg/h capacity before adding SD which had earlier been dried to a moisture content of 10 % and sieved to size 10mm. The mixture was then fedinto the WPCE kneading chamber for a thorough kneading into slurry form before extruding into a (20x 40x 150) mm mould which was hot pressed at 120°c and 1.12N/mm2 force to a thickness of 16.5 mm, breadth 36.5 mm and length 145.5 mm. Samples were thereafter cut into specific dimension in accordance with British Standard D373. Results show that clads produced from Miliciaexelsaat SD/NS mix ratio 20:80 were relatively low in water absorption, thickness swelling and linear expansion making it suitable for buildings protection in waterlogged areas. |

Title : Health Risks Prevalent among Workers in Tank Farms in Niger Delta, Nigeria
Authors : Grace Eyo Attih, John Ugbebor, Ejikeme Ugwoha
Abstract :
The study evaluated the health risks prevalent among workers in selected tank farms in Niger Delta, Nigeria by adopting a cross-sectional design where data were collected from 182 tank/depot workers purposively using questionnaire. A total of 200 copies of a closed ended questionnaire were administered to all cadres of staff which comprised of senior staff, middle and junior staff. Data were coded and analyzed at 95% confidence level. Most respondents agreed that workers sometimes inhale, and ingest hazardous chemicals, which spill-over their skin. This was further supported by the weighted mean result which criterion mean and grand mean scores is over 3.00 and 4.26 respectively for each company. Workers are exposed to diverse OHS risks at work, the most prevalent of which is inhalation of fumes from petroleum products during loading. Workers are also at risk of tripping and falling while climbing tanks on daily-basis to load and haul petroleum products; they may inhale or ingest hazardous chemicals that spill onto their skin; they face psychosocial hazards such as hypertension, boredom, anxiety; they are also exposed to flammable, noxious, and corrosive gases that are harmful to their health. The study recommends frequent inspection of machines; turn around maintenance of facilities and promotion of healthy work environment within the tank farms. |

Title : Occupational Health and Safety Hazards in selected Depots in Niger Delta, Nigeria
Authors : Grace Eyo Attih, John Ugbebor, Ejikeme Ugwoha
Abstract :
The study evaluated the health hazards prevalent among workers in selected tank farms in Niger Delta, Nigeria by adopting a cross-sectional design where data were collected from 182 tank/depot workers purposively using questionnaire. A total of 200 copies of a closed ended questionnaire were administered to all cadres of staff which comprised of senior staff, middle and junior staff. Data were coded and analyzed at 95% confidence level. most respondents agreed that some machines/equipment in their various workplace are not always in good condition which was further supported by the weighted mean result, with scores more than the criterion mean and grand mean of 3.00 and 4.10 respectively for each company. Most respondents disagreed that flammable substances like; PMS, AGO, HHK, solvent and other explosive-chemicals are not appropriately stored or handled in their workplace. This was further supported by the weighted mean result which scores were below the criterion mean and grand mean of 3.00 and 2.23 respectively, for each company. This study therefore recommends that government and supervising institutions should enforce compliance to OHS in industries, especially oil and gas companies so as to minimize hazards and risk levels. |

Authors : Henry- Unaeze Helen Nonye, Okoye Ruth Chinasa
Abstract :
The need to achieve food security for all initiated the development of new food products from available food sources. Objectives: The study evaluated the pasting and functional properties of flour blends made from African yam bean (Sphenostylis stenocarpa) and corn (Zea mays) seeds.African yam bean (AYB) seeds roasted at 1910C for 40 min and corn seeds oven-dried at 500C for 24 h were finely milled, and formulated into 5 flour samples in the ratios of AYB (70): Corn (30), AYB (50): Corn (50), AYB (30): Corn (70), AYB (100: 0), and Corn (100: 0) to yield one-third (1/3) of the daily dietary fiber requirement (12.7 g) of a reference man (70 kg).The samples and the control (wheat flour) provided 6 samples which were evaluated for pasting and functional attributes using standard procedures. Data generated were analyzed using the IBM Statistical Product for Service Solution (version 21.0) and presented as means and standard deviations. Analysis of variance (ANOVA) was used to compare the means and significance was accepted at p < 0.05. The results showed the range of pasting properties of AYB and cornflour samples as 1066.00BU to 2844.50BU for peak, 1008.50BU to 1687.50BU trough, 26.00BUto 1157.00BU breakdown, 1454.50BU to 2629.50BU final, and 298.50BU to 942.00BU setback viscosities; 6.23 to 7.00mins for peak time, and 67.730C to 84.800C pasting temperature). The functional properties ranges were 0.72% to 0.77% (bulk density), 1.98% to 2.04% (water absorption capacity), 0.73g/ml to 2.62g/ml (oil absorption capacity), 0.72sec to 2.03sec(wettability), 1.04g/ml to 6.64g/ml (swelling index), 60.650C to 71.000C (gelatinization temperature), 1.52% to 13.17% (foaming capacity), 2.03 to 5.82g/ml (emulsion capacity) and 0.62% to 1.41% (foaming stability). High starch yield, peak, and setback viscosity were observed. Samples could be used for making new and varied products. |

Title : Factors Associated With Pregnancy Occurrence Among Known HIV Positive Women In Rangwe Sub-County, Homa Bay County, Kenya Authors : Phelesia Agola Onguru, Daniel Ogungu, Aulo Tobias Ouma, Ogolla Sidney Onyango
Abstract :
Globally, the proportions of women of reproductive age living with HIV vary between regions, with significantly higher proportions in sub-Saharan Africa. The scale-up of multiple-drug antiretroviral therapy in Africa has changed childbearing dynamics for HIV-positive women, with an impact on pregnancy incidence, although there is little understanding of the factors associated with pregnancy incidence among these women. This descriptive cross-sectional study investigated the incidence of pregnancy among HIV positive women in Rangwe Sub-County, and identified the associated personal, medical and community factors, using semi-structured questionnaires administered to 244 women on antiretroviral therapy. Quantitative data was analyzed using descriptive statistics and logistic regression using SPSS v.23 (α=0.05), while qualitative data was subjected to thematic analysis. Over 95% of the women had conceived after being diagnosed HIV positive. Age, marital status and CD4 cell count were significantly associated with pregnancy incidence (p<0.05). Partner consent (p=0.034), and partner HIV serostatus (p=0.005) were significantly associated with pregnancy, unlike partner support, partner awareness of participant’s status, defaulting from ARVs, and community or family acceptance of childbearing (p>0.05). Women with undetectable viral load (HIV RNA <50 copies/mL) were 2.7 times more likely to get pregnant compared to women with detectable viral load (OR=2.71; 95%CI=1.8-3.22; p=0.028). The Ministry of Health and relevant stakeholders should improve on the strategies to enhance viral load and CD4 cell count monitoring, HIV status disclosure between sexual partners, and adoption of strategies that promote male partner support to women to get pregnant, and to use family planning methods of choice. |

Title : Morphological Characteristics of Lumber Pedicle: A Study of Adult Nigerian Cadaver
Authors : Oyakhire M. O., Harcourt S. L., Elijah, S. O.
Abstract :
Knowledge of pedicle morphometry is important in the surgeons’ ability to successfully apply a surgical screw to the spine of patients who need instrumentation for various reasons. This is more so considering that a wrongly placed pedicle screw can produce complications worse than the actual injury itself. Often these may present as spinal cord or nerve root injuries, pedicle fractures, vascular injuries, leakage of cerebrospinal fluid among several others. A total of 185 adult lumber vertebrae, prepared through soil and water maceration were used in this study. There were 34 sets of males and three sets of females. Craniocaudal increase was noted in Pedicle length and thickness from L1 to L5 but this was not statistically significant. Pedicle width was observed to increase in a similar manner. Females had higher pedicle values than their male counterparts and the least was 8.25 mm. The study concludes that pedicle dimensions vary among population and between sex and recommend proper pre-operative evaluation and assessments prior to surgical instrumentation on the lumbar spine. |

Title : Enablers of Innovation Implementation within Quantity Surveying Firms in Nigeria
Authors : Ajayi A.A., Alimi W.O.
Abstract :
Innovation has received significant attention in the last few years in both practice and academia. Implementation of innovation has proven to have delivered quality, product functionality, and productivity improvements in construction project delivery. Yet innovation implementation at the corporate level is low, such as within the quantity surveying firms (QSFs) in Nigeria. Hence, this study assessed the important key enablers of implementing innovation within QSFs in Lagos and Abuja, Nigeria. An explanatory research design was adopted to achieve the set objective. A comprehensive literature review was done to highlight the relevant enablers of innovation implementation. 120 and 78 questionnaires were sent out to QSFs duly registered with the Quantity Surveyors Registration Board of Nigeria (QSRBN) in Lagos and Abuja respectively. From the questionnaires administered, 96 and 59 questionnaires from Lagos and Abuja respectively were returned and used for this study. Collected data were analysed using both descriptive and inferential analytic tools. The analysed data revealed that from the list of twenty (20) enablers identified, the important enabler that could promote innovation implementation was an effective rewarding structure (incentive to innovate). The findings also revealed that there is no statistical difference between the opinions of the QSFs in Lagos and Abuja. This study implies that implementing innovation could be enabled by understanding the set of identified factors by QSFs for performance improvement of the industry. |
