Shear Wall Provision Influence on Medium Rise Multi-Storey Framed Building in Maiduguri

This study compares the aerodynamic behaviour of medium rise multi-storey frame structures with and without shear walls using the local wind gust of Maiduguri (47m/s) as primary data. The wind assessment was carried out in accordance with recommendations of British Standard and other relevant specifications. Analysis of the structural system was carried out using Extended Three-dimensional Analysis of Building System (ETABS) software; where the forces, maximum floor drifts and stresses are obtained and compared. The result shows that, the displacement fora 15 storey building with shear wall was 91.44% less than same without shear walls while with increasing storey height, the differences reduce; for example, the displacement for 20 storey building with shear wall showed 81.5% lesser than same building without shear wall. This signifies that building with shear wall resist aerodynamic load more efficiently principally due to the influences of the rigidity and strategic locations of the shear wall in the building. The shear walls are usually effective in stabilizing displacements on medium rise multi-storey buildings subjected to lateral forces from wind, seismic and explosive to satisfy serviceability criteria of H/500 stipulated by most conventional standard

Gastrointestinal symptoms in pregnancy among antenatal clinic attendees in Abubakar Tafawa Balewa University Teaching Hospital Bauchi, Northeast Nigeria

Background: Pregnant women are at increasing risk of GI symptoms such as nausea, vomiting and heartburns, most of these symptoms are as a result of the hormonal and physical changes associated with pregnancy. This study aimed to determine prevalence of gastrointestinal symptoms (GI) among pregnant women attending booking clinic at a Northeastern Nigerian Teaching Hospital.Methods: The study was a cross-sectional, questionnaire-based survey of four hundred and fifty-two pregnant women booking for antenatal care. Their sociodemographic variables as well as the presence or absence of gastrointestinal symptoms in index pregnancy were obtained at by the use of researcher-administered questionnaire. Data were analyzed and presented as frequencies and percentages. A 5% significance level (p <0.05) to test associations.Results: Two fifty-five women had heart burns (56.4%) while 235 (52.0%) had nausea in pregnancy, these were observed to be the most prevalent GI symptoms among the women. Diarrhea and hemorrhoids were the uncommon GI symptoms in the study population constituting 406 (89.5%), and 360 (79.6%) respectively. Easy fullness was noted in 39.8% of the women while vomiting was in 41.8% and constipation in 29% of the respondents. A significant association was observed (p value <0.05) between parity and development of anorexia and hemorrhoids in pregnancy (p values of 0.049 and 0.051 respectively) but not for the other symptoms.Conclusions: GI symptoms are common in pregnancy, the most prevalent symptoms are that of heart burns and nausea, while diarrhea is relatively uncommon

Accountability and Environmental Sustainability: Nigerian Maritime Experience

Maritime sector of Nigeria is one of the largest administrative agencies in African continent that has greater impacted to Nigerian and West African region economies. The industry expectation if managed very well, will significantly improve the economic development of Nigeria. Several reports in the sector provide evidence of non-performance, low productivity, corruption and non-compliance with the international maritime global best practice. In addition, the sector is marred with the challenges of political, regional instability and pirating within the coastal region. However, significant efforts have been made by the Nigerian government to improve on the sector in order to attract local and global investors in the industry. From the last political and present administration of Nigerian government has provide a good enabling environment for the growth of the industry. However, policy makers and government are expected to do more in the sector for the economic benefits of the country and West African region in general

Effects of Rainfall and Temperature Variability on Yam Production in Lafia Local Government Area, Nasarawa State, Nigeria

The study assesses the effects of rainfall and temperature variability on yam production in lafia Local Government Area of Nasarawa State, Nigeria. The research data were collected from secondary data from the existed literatures such as textbooks, journals, articles, seminar papers, encyclopedia which are most pertinent to this study. The rainfall and temperature data of the fourteen years (2001-2014) were collected from synoptic weather station of NIMET archives Lafia sub station where rain gauge and thermometer are used. The Statistics Package for Social Science (SPSS) software was used for the analysis. The derivatives of these data were computed and used for further analysis such as average of number of rainy and temperature variations of months of years under study. The yam data was collected in metric tons as unit of measurement per year for the fourteen years under study which shows that there is an upward increase trend in yam production in the area of study over the time span in gradual and steady state which has a variation in production, across the years under consideration of 0.843%. It is also indicated the effect of 0.186 (19%) of the variation in yam production was explained by the variation in rainfall, maximum and minimum temperature between the study periods. It’s further stated that the magnitude of effect by the predictors (rainfall, minimum and maximum temperature) on the dependent variable (yam) varies. Rainfall had a non-significant (P-value &gt; 0.05) effect of -0.269 and a coefficient value of -0.438. This by extension implies that for every unit (mm) decrease in rainfall over the period of time under investigation, yam production decreases by -0.438mt. The relationship between rainfall, temperature and yam using Pearson correlation shows that a weak negative relationship (-0.041) between rainfall and yam yield, a weak positive relationship (0.160) between maximum temperature and yam yield and there is a weak positive relationship (0.322) between minimum temperature and yam yield. The study identified increased production with non-significant positive effect of rainfall, maximum and minimum temperature on yam production. Since the study focused on the effects of rainfall and temperature variability on yam production in Lafia Local Government Area of Nasarawa state, without taking into consideration of other parameters like land use patterns and since rainfall and temperature are not the only parameters that affects yam production. the following recommendations are made: Agricultural Extension Officers (AEOs) should be deployed to guide farmers through routine visits, regular access to weather information to farmers by NIMET, application of irrigation  for growing of crops,  study of land use pattern should be considered and there is need for modern farm inputs and price control by government and Non Governmental organization.

Prevalence of hyperemesis gravidarum and associated risk factors among pregnant women in a tertiary health facility in Northeast, Nigeria

Background: One of the commonest symptoms observed in pregnant women before the 20th week of gestation is nausea and vomiting, an exaggeration of these symptoms hyperemesis gravidarum (HEG) could result in maternal and fetal catastrophes and even death. The objective of this study was to determine the prevalence and associated risk factors for hyperemesis gravidarum among pregnant women at booking.Methods: A prospective institutional based study design was done among 452 pregnant women seen at booking in a tertiary hospital in Northeast Nigeria from the 1st February 2019 to 30th June 2019. Data was summarized using descriptive statistics. OR was used to measure significant risk.Results: The observed prevalence of hyperemesis gravidarum among pregnant women in the study is 44.9%. The Majority (81.4%) of these women were between the age range of 21 and 35 years. Mean age of 27 years. Multiparity (33.4%), previous (44.9%) and family history of HEG (31.6%) were identified as important risk factors for developing HEG. Grand multiparity (11.5%) and gestational age less than 13 weeks (6.64%) were however less likely observed to be risks for HEG.Conclusions: HEG is a common problem in pregnancy with almost half of the number of pregnant women at booking affected. Multiparity and past history of HEG are pointers to developing the condition and it should be looked out for among at risk group of pregnant women, so that early intervention can be instituted to avoid any possible adverse outcome

Effects of Rainfall Variability on Cassava Yield in Owerri North Local Government Area of Imo State, Nigeria

Agriculture in Nigeria is the main source of food and major employer of labour with about 60% of the Nigerian population engaged in Agriculture. It is predominantly ran-fed and hence vulnerable to climate change. This study assessed the effects of rainfall and temperature variation on cassava in Owerri North Local Government Area of Imo State, Nigeria. Data for the study were collected from the Imo State Agricultural Development Programme for the period of 22years (1995-2017). The data were analyzed statistically and the results revealed that there was minimal variation in rainfall and temperature characteristics, which translates into proportional variability in cassava yield in Owerri North Local Government Area, during the period of study. The study also revealed poor yield with non-significant positive effect of rainfall, maximum and minimum temperature in cassava yield. With reference to the study outcome, it was recommended that weather information should be disseminated to crop farmers to equip them with proper timing, adaptation and mitigation strategies for agricultural practice in the region. This would reduce the adverse effects of climate variability on crop production. Also, it was recommended that since rainfall and temperature do not account for one hundred percent of the determinants of crop yield, other factors such as soil fertility and farm management practices should be explored in order to ensure maximum yield of crops in Owerri, Imo State of Nigeria.

Assessment of the Effects of Flood on Agricultural Land Use in Doma Local Government Area, Nasarawa State, Nigeria

This study aimed at assessing the effects of flood on agricultural land use in Doma Local Government Area, Nasarawa state, Nigeria. In order to achieve the objectives of the study, information on the causes effects frequency and magnitude of flood on agricultural land use were needed from primary and secondary source of data. The primary data were obtained through the use of structured questionnaire, field observation and measurement and ten years rainfall data (2004-2014). The rainfall data were obtained from Nigeria meteorological agency (NIMET), Lafia, Nasarawa state. Rainfall data obtained were used for rainfall trend analysis for the study. The secondary data include information from relevant text such as journals, newspaper dictionary, encyclopaedia textbooks, internet and web and related past students dissertation and thesis. Basic statistical techniques such as the computation of totals, mean, and standard deviation were employed for the analysis of rainfall data. Descriptive statistics were adopted to analyze the result from the questionnaire and simply linear regression analysis were used to determined rainfall trend for this work. The study shows that there has an appreciable effect of flood in the    study area which is due to many factors such as human activities but is greatly influenced by climate. This evident in the study as about 44.1% and 21.8% of the total respondents have been engaged in farming for 21 years and above, and 16 to 20 years respectively and are thereby able to explain clearly the effects they home observed experienced over time. The finding also revealed that 1.76% of the respondents have lost a total 15 hectares of farm land, 30.59% have 416 hectare 23.53 have lost 480 hectares, 14.71% lost 500 histories and 7.06% 600 hectares respective. This indicates a great destruction farm lands in the area and invariably a decrease in food production. The state disaster management and other agencies charges with disaster management in the state level should be properly funded in order to respond to the challenges of sudden of occurrences of natural disaster in future.

Phytochemical analysis, analgesic and antipyretic properties of ethanolic leaf extract of Vernonia amygdalina Del.

Introduction: Vernonia amygdalina Del. has been traditionally used in relieving pain and inflammatory conditions as well as in treatment of feverish conditions by local people of the North-east Nigeria. Consequently this study aims at evaluating the phytochemical content, antipyretic and analgesic properties of V. amygdalina (biter leaf).Methods: The leaf of V. amygdalina was soxhlet extracted with ethanol and sequentially partitioned using solvent of different polarities. Phytochemical test was conducted to ascertain the secondary metabolites present in the extract using standard procedures. Acute toxicity (LD50) of the extract on laboratory rats was estimated by following protocols of Lorke. The antinociceptive activity of the ethanolic extract was also evaluated using acetic acid induced pain and hot plate method.Results: The results revealed the presence of tannins, phlobatannins, saponins, carbohydrates, cardioactive glycoside, flavonoids, alkaloids, steroids and terpenes. Anthraquinones were absent in the extract. The intraperitoneal LD50 was found to be 3721 mg/kg. On administration of 5000 mg/kg dose of the extract via oral route, there was no dead. The extract demonstrated significant antinociceptive activities as 36.0 &plusmn; 0.81, 43.8 &plusmn; 0.11 and 52.8&plusmn;0.37 (Mean number of writhings) respectively for the doses 600, 400 and 200 mg/kg i.p.) as compared to the control (60.0 &plusmn; 0.11). High dose of 400 mg/kg significantly reduced rectal temperature (P &lt; 0.05)Conclusion: These results demonstrated the medicinal potentiality of V. amygdalina and might be used as analgesic, and antipyretic agent. Phytochemicals found in such as flavonoids, tannins, alkaloids and steroids seem to be implicated in having such pharmacological activities

Evaluation of Environmental Effect of Shiroro Hydropower Dam on the Downstream Communities of Shiroro Local Government Area, Niger State, Nigeria

This study evaluates the environmental effect of Shiroro hydropower dam on the downstream communities. The main objective of this study is to investigate the environmental effects of Shiroro hydropower dam on the downstream communities. A suitable conceptual framework was formulated and obtained data on the environmental impacts of dam on downstream communities, followed by a comprehensive literature review for viable information on the study. Three communities were used as case studies and quantitative method was  used as an appropriate research paradigm such as structured questionnaire survey (with predominantly quantitative questions) and  relevant data was obtained from the study area. Subsequently the data was analysed using descriptive, factor analysis and Kruskal-Wallis test as well construct reliability and validity analysis. From a broad range of environmental impacts, core environmental impacts were determined. The core impacts include changes in riparian vegetation, changes in river water quality, changes to channel shape and changes in floodplains among others. Similarly, control techniques were identified to lessen the effect of the impact and the result revealed that watershed management, water pollution control, management of water releases, fishing regulation, fish hatcheries and fish passage facilities were the core control techniques. The result of Kruskal-Wallis test revealed that majority of the environmental impacts affecting the communities under study is significantly and statistically different while the Cronbach alpha for internal consistencies of the constructs of the questionnaire was 0.745, hence high enough for generalising the result.
