Omokhoa Adeleye,O.A. Akoria; Z.O. Shuaib and O.D. Ogholoh
Asian Journal of Medical Sciences , 2010,
Abstract: This study was undertaken to elicit barriers and knowledge gaps regarding the benefits of family planning among women in Irrua, Edo State, Nigeria. Using a cross-sectional design, a structured questionnaire was administered to 180 consenting women attending antenatal clinic sessions in a large hospital. The control of family size, 72/180 (40.0%) and child spacing, 64/180 (35.6%) were the major benefits of family planning stated. The most direct benefit to maternal health - absence of pregnancy complications - was the least mentioned (5%). A total of 18/180 (10.0%) stated that family planning w as of no benefit. No statistically significant association was demonstrated between educational levels and the knowledge of family planning benefits. Respondents aged 30 - 49 years were more likely than the younger ones to state child spacing as a benefit of family planning methods [logistic regression: p = 0.004; OR = 2.61 (95% CI = 1.37 - 4.98)]. The commonest reasons for objecting to family planning were the fear of infertility, 28/114 (24.6%), incom plete family size, 24/114 (21.1%), side effects of contraceptives, 19/114 (16.7%) and partners’ objection, 17/114 (14.9%). This study demonstrates important knowledge gaps with respect to family planning benefits. T his could reflect poor knowledge delivery or uptake on family planning. The findings suggest that women’s knowledge and experiences regarding family planning are crucial to interventions on fertility control. Overall, the study shows that the identified knowledge gaps and barriers reflect opportunities for holistic interventions including needs-sensitive health education for males and females on family planning.

Journal of Biological Sciences , 2011,
Abstract: Bio-control methods have become a common practice in horticulture and crop husbandry due to the attendant negative impact of fungicides and other chemical agents on soil, vegetation and environment. Most fungicides accumulate in plant tissues and subsequently trigger carcinogenic effects in animals and humans. The leaf extracts of Ficus thonningii, F. saussureana, F. exasperata and F. sur were screened for antimicrobial properties on eight (8) fungal species which included Aspergillus flavus, A. niger, Botryodiploidia theobromae, Fusarium oxysporum, F. solani, Penicillium chrysogenum, P. oxalicum and Rhizopus stolonifer and two (2) bacterial species viz; Pseudomonas spp. and Klebsiella spp. which were isolated from the rot portions of tubers of Dioscorea rotundata. The extracts from the Ficus species had low antimicrobial effect at 25 and 50 mg mL-1 concentrations while a significant arrest of mycelia growth was observed at 75 and 100 mg mL-1 concentrations. The presence of alkaloids, flavonoids and cardiac glycosides in the leaves of these species may have conferred the antimicrobial properties on these species. Application of the fungal pathogens isolated on healthy tubers and the subsequent development of rots confirmed these organisms as the natural pathogens of this crop. The extracts from all the four Ficus species exerted significant antimicrobial effect on all the test organisms at 75 and 100 mg mL-1 concentrations and its application at these concentrations would help to minimise infection and spoilage during and after storage and improve farmers revenue.

Business Management Dynamics , 2011,
Abstract: The accelerated rate of urbanization in all forms and the geometric population growth in Nigeria have been generating serious environmental problems and concern for both the government and interested stakeholders. Notably among which include problems of accommodation, over-stretched and poorly maintained facilities, roads, traffic congestion, undirected drainage systems, etc are few of the problems plaguing most of the country’s urban centres. It is the foregoing scenario that has necessitated the recent concern about the sustainability of our environment taking into consideration the increasing rate of environmental waste and degradation going on in the country. Despite the efforts of the various organizations and interest groups spear-heading campaigns for progressive changes in policies, laws, technologies and development strategies toward enhancing urban qualities, the achievement has been rather very low and minimal. This development has created great sustainable challenges for not only the government at various levels but also the stakeholders and other interest groups in the country especially in the area of human settlement and sustenance of the environment in the area of good transportation networks, potable water supply, sanitation, effective and efficient waste management, elimination of social conflict and crime. This paper examined the efforts of government at tackling the barrage of challenges hampering issue of sustaining urban growth phenomenon over the years through poverty reduction and economic empowerment strategies, good governance and enhanced urban development international partnership strategies. The paper concludes that sustainability of urban growth and development can only be anchored on government sincerity of purpose and committed political will in an atmosphere of peaceful democratic setting.

Tolstokorov A.S,Sarkisian Z.O.
Saratov Journal of Medical Scientific Research , 2012,
Abstract: Objective of the study: determination of the degree of influence of bilirubin in the blood during obstructive jaundice, on blood clotting. Methods. A retrospective study of case histories of patients with obstructive jaundice who have been treated at the Regional Hospital of Saratov in the period from 2000 to 2010. Results. The results confirm the assumption that the causes of bleeding in obstructive jaundice is hepatic failure. Conclusion. Absence of bile in the small intestine in obstructive jaundice is not the cause of bleeding. Bile acids are not involved in metabolizing fat-soluble vitamin K1
Study of high frequency MHD modes from ECE radiometer in Tore Supra

EPJ Web of Conferences , 2012, DOI: 10.1051/epjconf/20123203012
Abstract: Tore Supra ECE diagnostic has been recently upgraded to study MHD modes driven by energetic particles up to 400 kHz. To improve the measurement sensitivity, the ECE signals of the 32 channels radiometer were amplified just below the saturation limit and sources of noise were investigated in order to keep it as low as possible. With such an improvement, fast particle driven modes with frequencies up to 200 kHz were detected. A 4-channel correlation ECE system using YIG filters with tuneable frequency was also installed. It allows fine radial scans of MHD modes and correlation length measurements. For the two kinds of YIG filter in use, the minimum frequency separation between two ECE channels that could be achieved was established measuring the correlation coefficient between the respective radiation noises. Finally, by modelling the ECE radiometer taking into account the antenna radiation pattern and the vertical position of the ECE beam relative to the plasma centre we improved the data analysis tools, thus giving a better determination of the phase radial structure of ECE oscillations. The poloidal structure of MHD modes can then be identified from ECE data and, for off axis ECE lines of sight, the direction of the plasma rotation can also be determined. This method allows identifying the occurrence of an inverse cascade of electron fishbone modes ranging from m/n=4/4 to 1/1 (m and n are the poloidal and toroidal mode numbers, respectively) which appears in lower hybrid current drive plasmas.

International Journal of Electrical and Power Engineering , 2012,
Abstract: A fluidized bed, using locally available material for the combustion of Okpara coal for generating steam to drive turbine for electricity generation, has been designed, constructed and commissioned. Two areas of investigation were looked into in this research. These were combustion at different coal particle sizes from 4.5-50.0 mm and steam generation at constant coal particle size with bed temperature ranging between 700 and 900 C. Results shows that a temperature of 153 C maximum was obtained at atmospheric combustion and much higher temperature could be anticipated at higher pressure with this type of bituminous coal and combustor.

Rational Pharmacotherapy in Cardiology , 2012,
Abstract: Early glucose metabolism disorders (GMD) are of interest in development of effective approaches to prevention of type 2 diabetes mellitus (DM). Data of international clinical trials shows that early GMD are an independent risk factor for cardiovascular disease. The possibilities of GMD prevention and early treatment are discussed. Antihyperglycemic medications classification, their mode of action and efficacy are presented from evidence-based medicine point of view. This data confirms that successful DM primary prevention at early stage of GMD reduces the risk of cardiovascular complications.

Rational Pharmacotherapy in Cardiology , 2006,
Abstract: Aim. To study the influence of long-term therapy with perindopril on the heart inotropic function in patients with chronic postinfarction aneurismMaterial and methods. 21 patients suffering ischemic heart disease with postinfarction cardiosclerosis, chronic aneurism of left ventricle and chronic heart failure of functional class III-IV according to NYHA were observed. All patients took perindopril, 2-4 mg daily. Before and after 6 months of therapy myocardial contractile function of left and right ventricles was studied by balanced radioventriculography with segmental and phase analysis of histogram.Results. In patients with chronic postinfarction aneurism significant structural and functional abnormalities were revealed: reduction of left ventricular ejection fraction up to 17,8 ± 3,2 %, the same for right ventricular up to 22,1±4,4 %, their considerable dilation with reduction of filling and expulsion velocity. After 6 months of therapy with perindopril improvement of clinic status of patients, tendency towards increase of both ventricles general ejection fraction, enlargement of maximal filling velocity and filling velocity during 1/3 of diastole as well as tendency to reduction of both ventricles end diastolic and systolic volumes were registered. In left ventricle there were normokinetic zones in 35 (21%) segments, hypokinetic zones in 24 (14%), akinetic zones in 54 (32%) and dyskinetic zones in 17 (10%) segments. In right ventricle there were normokinetic zones in 45 (27%) segments, hypokinetic zones in 62(37%), akinetic zones in 54 (32%) and dyskinetic zones in 7 (4%) segments. After 6 months of therapy with perindopril tendency towards improvement of local myocardial contractility was registered.Conclusion. In patients with chronic postinfarction aneurism deterioration of general and local myocardial contractility were registered. Accurate link between left ventricle local myocardial contractility and localization of aneurism were not revealed. After 6 months of therapy with perindopril tendency towards improvement of general and local myocardial contractility of both ventricles was registered.
Hydraulic (Flow) Unit Determination and Permeability Prediction: A Case Study of Block Shen-95, Liaohe Oilfield, North-East China
O.D. Orodu,Z. Tang,Q. Fei
Journal of Applied Sciences , 2009,
Abstract: This study analyzes three prediction approaches of the Bayesian method for predicting Hydraulic Unit (HU) and consequently predicts permeability for Block Shen-95. These approaches are intersection of multiple well-logs, independent mulitple well-logs and mutually exclusive multiple well-logs. In this study, HU was delineated to efficiently compute permeability and served as the building block of structural model for enhanced simulation study. HU is defined by the flow zone indicator concept from the modified Kozeny-Carmen equation. The Bayesian method was used to predict HU at uncored wells. This is done by first constructing a probability database through the integration of established HU and well-log responses at cored wells. HU is then inferred from the database using well-log responses. By comparison, estimated permeability from predicted HU gave an overall improved permeability match to that of traditional statistical methods. More so, mutually exclusive multiple well-logs proved more favourable. The highlight is that significant relationship exists by integrating reservoir performance with HU distribution indicating that reasonable prediction was obtained at uncored wells from the use of the mutually exclusive approach. The distribution was made possible by interwell HU correlation using depositional cycles as a framework but with modification. This integration step qualitatively examines prediction accuracy.

Abstract: This study examined the environmental impacts of small scale industrial establishments in Akoko region of Ondo state of Nigeria. In order to do this, 204 small enterprises which constitute 50% of the entire plants in the region were sampled. The household heads of the closest residential buildings to the sampled small enterprises were also interviewed, in order to test residents perception of injury they suffered from the operation of these enterprises. Data collected were analyzed using cross tabulation and simple percentages. The study found out that there is substantial lack of compliance with stringent environmental rules on production and discharge of effluents by these enterprises. The study further discovered that informal enterprises do pollute the environment more than formally registered ones, following the difficulty of controlling them since they operate outside the regulation of government and its supervising agencies. Moreover, the study found out that most of the wastes generated are not being recycled and are poorly disposed of to the extent that they tend to constitute health hazards to people. Finally, the study recommends that for maximum benefits to be derived from this industrial sub sector, efforts must be made to minimize the noxious impacts through recycling of the wastes so that the environment can be made livable.
