Natural background radiation dose rate levels and incidences of reproductive abnormalities in high radiation area in Abeokuta, Southwestern Nigeria  [PDF]
Nnamdi Norbert Jibiri, John Bamidele Famodimu
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.511141
Abstract:

A 10 y (1999-2008) birth records from two public and most accessible maternity hospitals locally in the city of Abeokuta, Nigeria were used to investigate the possible association of high outdoor gamma radiation exposure on reproductive abnormalities in the city. From the delivery record of 11,923 births in the period under study, a total number of 485 incidences of reproductive abnormalities were recoded. These incidences comprise 228 multiple births, 190 still births and, 67 premature births. Using the available terrestrial gamma radiation exposure data for the city and different reproductive abnormalities, regression assessment was carried out using the Pearson Product Moment (PPM) correlation statistics. The correlation showed that the incidences of reproductive abnormalities and the radiation dose levels were negatively correlated and correlation coefficient values were very low for each of the reproductive abnormalities considered. Factors such as socio-economic potentials of patients, dietary and other environmental factors may have substantial influence on the reproductive defects in the area other than radiation. However, the present study has added to the radiometric information needed in understanding the relationship between natural outdoor radiation exposure and occurrences of reproductive abnormalities in areas of high radiation in the country.

Bamidele Moses Kuboye
Communications and Network (CN) , 2018, DOI: 10.4236/cn.2018.104013
Abstract: Long Term Evolution (LTE) is designed to revolutionize mobile broadband technology with key considerations of higher data rate, improved power efficiency, low latency and better quality of service. This work analyzes the impact of resource scheduling algorithms on the performance of LTE (4G) and WCDMA (3G) networks. In this paper, a full illustration of LTE system is given together with different scheduling algorithms. Thereafter, 3G WCDMA and 4G LTE networks were simulated using Simulink simulator embedded in MATLAB and performance evaluations were carried out. The performance metrics used for the evaluations are average system throughput, packet delay, latency and allocation of fairness using Round Robin, Best CQI and Proportional fair Packet Scheduling Algorithms. The results of the evaluations on both networks were analysed. The results showed that 4G LTE network performs better than 3G WCDMA network in all the three scheduling algorithms used.

Open Journal of Depression (OJD) , 2018, DOI: 10.4236/ojd.2018.72002
Abstract: Background and Aim: Research has shown that 30% - 70% of people who have lived in war zones suffer from symptoms of depression, with exceptionally high rates documented among heads of households. Thus, this study aims to determine the prevalence and correlates of depression among victims of armed-conflict in Dogonahawa, North-Central Nigeria. Methods: A multistage sampling of households was employed to select 270 respondents aged ≥ 18 years. A face-to-face interview was conducted using the Revised Beck Depression Inventory-11 to collect data on depression. Results: The prevalence of depression was 38.5% in all respondents, 45.2% and 28.6% among heads of households and the dependants respectively. The odds of having depression was more than twice among heads of households with income below N20,000.00 compared to those earning above N50,000.00 (OR = 3.02, P = 0.253), but was decreased among males, those engaged in professional jobs and those with household size of less than five members compared to females, being engaged in non professional jobs and having more than five household members respectively (OR = 0.198, P = 0.002; OR = 0.049 and OR = 0.199; P = 0.012 and OR = 0.193; P = 0.001 respectively). Conclusion: The results point to the importance of disaster preparedness generally and specifically, with particular attention to household heads who are females, non professionals, with low income and larger household size.

Hepatitis Research and Treatment , 2011, DOI: 10.1155/2011/157089
Abstract: Background. Hepatitis B virus (HBV) infection is a well recognised occupational health hazard preventable by vaccination. Objectives. To determine the knowledge of operating room personnel (ORP) in Nigeria about the Hepatitis B vaccine, their perception of Hepatitis B vaccination and vaccination status against HBV. Methods. Four university hospitals were selected by simple random sampling. A structured questionnaire was administered to 228 ORP after obtaining consent. Result. Only 26.8% of ORP were vaccinated against HBV. The primary reason for not being vaccinated or for defaulting from vaccination was lack of time. Differences in age, sex, duration of practice and respondent's institution between vaccinated and unvaccinated ORP were not significant ( ). The majority (86.8%) had the awareness of the existence of Hepatitis B vaccine. 83.8% of respondents believed that the vaccine should be given to the ORP as part of work place safety measures. The majority were aware of the modes of transmission of HBV infection. 78.9% of respondents believed that Hepatitis B vaccine is safe and 81.1% would recommend it to another staff. Conclusion. Despite a good knowledge about HBV infection and vaccine, most of ORP are still not vaccinated. Hepatitis B vaccination should be a prerequisite for working in the theatre, hence putting surgical patients at reduced risk. 1. Introduction The most serious occupational health hazard faced by health care workers worldwide is exposure to blood-borne pathogens. These blood-borne pathogens are mainly Hepatitis B, C, and HIV infection. Hepatitis B is by far the most dreaded with over 2 billion people affected worldwide and 350 million people suffering from chronic hepatitis B virus infection [1]. It is more infectious than the other blood-borne pathogens and estimates of the risk of a single needlestick injury indicate a risk of 300 hepatitis B virus infection (30% risk), 30 hepatitis C virus infection (3% risk) and 3 HIV infection (0.3% risk), per 1,000 respective exposures [2]. In the United States, the incidence of HBV infection among all health care workers is estimated to be 3.5 to 4.6 infections per 1000 workers, which is 2- to 4-times the level for the general population [3]. The disease is thus more likely in health workers in Nigeria, a country with high prevalence of the disease. Among health care workers, operating room personnel are at a high risk of infection with blood-borne pathogens through blood contact [4]. This group of health workers has been shown not to follow standard precautions and not to report all
Reading Errors Among Selected Second Language Readers: Implications for Reading Instruction
Olushola Bamidele Are
The Social Sciences , 2013, DOI: 10.3923/sscience.2010.545.553
Abstract: This researcher observes that there are divergent positions among scholars regarding the roles of experiential factors and linguistic factors in reading incompetence among L2 readers. This research was conducted with a view to determining the exact sources of reading errors among selected second language learners. The goal was to suggest strategies of reading improvement, using the context of the research as a microcosm of Nigeria and, by extension, other second language contexts. It emerged that reading competence was typically low. However, it is significant that linguistic inadequacies accounted for the bulk of the reading errors identified. This researcher advocates an approach to reading instruction which emphasizes wide reading that is extensive reading. This approach not only generates interest in reading but also creates the opportunity for the learners to gain exposure to data of the target language thereby improving their linguistic skills and subsequently improving their L2 reading.
Conceptual Issues in Second Language Research in Africa
Olushola Bamidele Are
Linguistik Online , 2013,
Abstract: This paper is an overview of some of the complications associated with conceptualizing second language in African societies, particularly with reference to European languages. Most popular opinions and many scholarly insights appear to define second language mainly in terms of sequence of acquisition. From this perspective, the term second language refers to a language learnt in addition to a previously acquired one. While this view of second language actually applies to many African situations, there are complex bilingual and multilingual situations in Africa that pose serious conceptual problems when viewed from the standpoint of this dominant view. This paper raises the need for scholars to be conscious of these situations, and the variations in the conception of second language that consequently exist, so that divergent perspectives of second language can be better accommodated in the emerging global academic community
Nigerian English in International Business Communication: Issues, Challenges and Prospects  [PDF]
Olushola Bamidele ARE
Open Journal of Modern Linguistics (OJML) , 2016, DOI: 10.4236/ojml.2016.63017
Abstract: Effective communication is a crucial factor in business success in the global village that the world has come to be. In Nigeria, the overwhelming proportion of business with the outside world is conducted using the English. The need for Nigerian business people to use the language effectively will obviously contribute to success rates in their various interactions with business people from across the globe. However, as English becomes more domesticated in Nigeria, and as local varieties become more entrenched and less stigmatized, many Nigerians including those involved in international business may no longer be adequately conscious of the fact that the peculiar Nigerian ways they speak may pose fundamental communication challenges to non Nigerian business partners who may not be quite familiar with “Nigerian English”. This paper explores these challenges by systematically aggregating findings from diverse practical observations of international business communication situations involving educated Nigerian. Based on some observed challenges, the paper advances some pedagogical innovations from the field of intercultural communication; to prepare Nigerian L2 English learners for enhanced oral communication performance in the international business world without having disparaging attitudes towards local varieties of English.
AWARENESS AND COMPLIANCE OF ANTITETANUS IMMUNZATION AMONG ADULT FEMALES IN A TERTIARY INSTITUTION IN NIGERIA
JO Bamidele, SH Umoh
African Journal of Clinical and Experimental Microbiology , 2004,
Abstract: The purpose of this study was to investigate the awareness level and the compliance to anti-tetanus immunization among adult females in an urban community in South West of Nigeria. The rationale for the study was informed by the fact that high incidence of tetanus infections and deaths are still being reported from our clinics regularly. A total of 394 female workers and students of LAUTECH University and its Teaching Hospital participated in the cross-sectional survey. They were selected using the stratified sampling procedure. A pre-tested structure but open-ended questionnaire was administered on the respondents. The result of the analysis showed a high level of awareness (69. 8%) of anti-tetanus immunization among the respondents and a high significance association was found between the level of awareness and respondent's profession (X= 7. 65; p < 0. 0011). Majority of the respondents (56.1%) took their last dose of anti-tetanus immunization during their last pregnancies. More than one third (37.2%) of the 148 respondents who ever gate birth took only one dose or none during their last pregnancy, thus putting into question the immunological status of those mothers and the children they gave birth to then. It was concluded that despite the high level of awareness among the respondents, compliance was quite low. It is recommended that government should provide logistic supports to make immunization programme accessible on a sustainable basis to everybody in the country. Activities should be put in place that will promote behavioural change in women so that they can go for anti-tetanus immunization. Key Words: Antitetanus immunization, adult females; awareness; Compliance. Afr. J. Clin. Exper. Microbiol. 2004; 5(2): 208 – 216.
Growth of seashore paspalum, (Paspalum vaginatum L) in soil contaminated with crude petroleum oil
JF Bamidele, A Igiri
Journal of Applied Sciences and Environmental Management , 2011,
Abstract: The effect of crude oil contaminated soil on the growth of seashore Paspalum ( Paspalum vaginatum .) seedlings was investigated. Plants were grown in soil containing different concentrations: 0%, 0.5%, 1.0%, 2.0% and 3% (w/w) of Abura crude petroleum oil. Growth parameter such as shoot number, shoot length, leaf area and biomass accumulation were evaluated. The results showed that crude oil imposed physiological stress in the seedlings. There was a dose response decline in all the growth attributes examined. There was also a significant difference in plant growth with respect to time of crude oil application. At the highest applied concentration(3 % [w/w]), plants grown in soil previously contaminated with petroleum oil showed about 50 % reduction in biomass accumulation when compared with the uncontaminated control whereas established plants post -treated with crude petroleum oil showed a 30% reduction. There was no mortality at any of the crude oil concentrations to which to plant was exposed. The experiment demonstrated the potential of using Paspalum vaginatum for phytoremediation

Bamidele A. OJO
The Turkish Online Journal of Distance Education , 2009,
Abstract: This paper examines the question of distance education and its pivotal role in promoting social change and development in Africa. It also discussed within the context of the global digital divide and the ongoing need for collaborative effort at global education, the limitation imposed by the socio-economic and political environment on the continent. The paper in its findings conclude that the crisis within African societies constitutes a serious challenge to the implementation of and the effectiveness of distance education in Africa and therefore contributes to the widening of the digital divide rather than reducing it.
