Explorations of Respectability and Resistance in Constructions of Black Womanhood at HBCUs

Somewhere in her college experience she must have an opportunity to develop poise, to increase her self-esteem and to establish a sense of her worth and dignity as an individual. She must experience peace and beauty in her environment and she must be accorded the respect and courtesy, which is so lacking in her life on the outside. The education of the Negro woman should give her an opportunity to exhaust to the fullest her powers of expression and creativit

Rate of isolation of streptococcus species from children with bacterial infections: an indication for introduction of streptococcal vaccines

Background: Streptococcus species are among the commonest bacterial causes of childhood morbidity in developing countries. Streptococcal diseases in children have not been as well characterized in Nigeria as it has been in industrialized countries. The rudimentary nature of public health surveillance makes the true epidemiology of the disease difficult to ascertain. The predominance of Streptococcus pneumoniae in the causation of invasive diseases has led to the advocacy of inclusion of pneumococcal vaccine in the National Programme on Immunization. However, local data critical to inform on vaccine deployment are scarce, thus the need for the present study. Objective: To study the rate of isolation of Streptococcus species from children aged zero to 15 years, with suspected bacterial infections. Materials and Methods: Laboratory records of results of bacteriological studies of samples from children with suspected bacterial infections in University of Abuja Teaching Hospital from January 2008 through December, 2010 were retrieved and analyzed for bacterial growth. Data analysis Version 3.5.1. Statistical significance was set at p < 0.05. Results: A total of 2,247 samples were received during the study period. Of the 1,242 bacteria isolated, 502 (40.4%) were Staphylococcus aureus, 232 (18.7%) were Escherichia coli and 146 (11.8%) were Streptococcus species: 78 were isolated from blood, 9 from sputum, 11 from throat swabs and 28 from other sites while urine and eye swabs had 10 each. One hundred and six (72.6%) of the streptococci were from children aged 5 years and below. Most of the Streptococci (88.1%) were untyped. Among the 17 Streptococcal isolates typed, 10 were Streptococcus pneumoniae and three were group B Streptococcus. Conclusion: Streptococcal infections remain an important cause of severe disease in children in Nigeria. The use of effective, safe and affordable vaccine could significantly reduce morbidity from these infections, thus suggesting the need for more studies to conclude on streptococcal vaccine deployment.Key words: Streptococcal infections, Nigeria, Streptococcal vaccine

USE OF OPEN SOURCE TECHNOLOGY FOR EFFECTIVE ACADEMIC LIBRARY SERVICES IN NIGERIA

This study focuses on the need for academic libraries to adopt open source software technology for effective library services in Imo State, Nigeria. Descriptive survey research method was used to elicit responses. About 82 respondents consisting of librarians from the six academic institutions in the state were used for the study. Consequently, 82 copies of the questionnaire were administered and 63 representing 78% were returned. Descriptive statistics were used to analyze the data gathered. The results indicated that out of the 6 academic libraries involved in the study 1 is presently using D space and word press while others are yet to commence any form of a digital management system. The finding of the study shows that certain factors such as lack of technological knowledge for its adoption 58(92%) passive attitude towards the use of technology by management 53(84%) lack of Internet facilities to download and use software 50 (79%) amidst others were found to be militating against the provision and utilization of information resources and services. The study recommends that academic libraries should key into the open source technology because it is free, stable, adaptable and supported by a network of global community. This is imperative for academic libraries in Nigeria to bring back their users

Spatial Analysis Flood Risk Exposure in Ajeokuta Using Geographic Information System (GIS)

Heavy floods in Nigeria have shown increasing trend in recent years. Ajeokuta is one of the areas affected annually by flood due to its location along the river Niger basin.  Flood risk mapping and analysis are vital elements for appropriate land use planning in flood prone areas. The aim of this paper is to demarcate flood risk potential areas and determine the spatial impact of the recent major flood event in Ajeokuta using Remote Sensing and GIS techniques. Identified flood inducing factors in the study area, such as slope, elevation, drainage density, proximity to the river and land use were reclassified and combined to delineate flood risk zones using multi-criteria approach in a GIS environment. The idea was to identify the areas with the highest number of flood inducing factors and assess its proximity to the inundated areas during the recent flood events as a criteria for determination of locations for future flood events. Moderate resolution imaging spectroradiometre (MODIS) data of NASA terra satellite, SRTM, Landsat image with resolution of 30m, geographical map of the study area and geographical information system (GIS) were used for this purpose. Each of the flood indicators was reclassified into four which included high risk, moderately risk, low risk, and no risk  through  ranking process. Flood risk map (FRM) was later generated by overlaying the reclassified maps of all the parameters using addition operator and validated with a view to assisting decision makers on the menace posed by the disaster. The flood risk map revealed that the very high risky places covered area of 376.31 square kilometers (27.63%) while high risky covered 322.88 square kilometers (23.71%), The low risky areas covered 151.76 square kilometers (11.14%)  and areas free from risk covers 511.040 square kilometers (37.52%). This analysis further revealed that 56 settlements are within the very high risk zone these  includes  Geregu, Gbokojo, Adogu, upake, Adogo, Achaga, Badogo, upaga etc Keywords: Risk, Flood Disasters, GIS, S.R.T.M, MODIS DOI: 10.7176/JEES/10-8-07 Publication date:August 31st 202

Amelioration of Hyperglycemia and Dyslipidemia in Alloxan-Induced Diabetic Rats Using Citrulluslanatus and Persea Americana

Dyslipidemia has been observed to play an integral role in the pathogenesis of micro and macrovascular complications in diabetes mellitus patients. The complications were assessed via atherogenic index (AI), Coronary risk index (CRI) and Cardiovascular risk index (CVRI).The study was to investigate the amelioration of hyperglycemia and dyslipidemia in alloxan induced rats using watermelon and avocado seeds. A total of Forty rats were divided into eight groups of 5 rats accordingly. Diabetes was induced with a single dose of alloxan (100mg/kg) body weight and serum glucose was taken 72h after induction of confirm diabetes. Amelioration of hyperglycemia and dyslipidemia started on the 6th and 9th day of the experiment respectively. The result obtained from the phytochemical analysis showed that the aqueous extract of Citrulluslanatus and Persea Americana gave positive reactions for Alkaliods, tannins, flavonoids and saponins. The data showed that Alloxan caused significant increase in Glucose, TC, TGs and LDL in the untreated diabetic rats. On the other hand HDL was significantly decreased. The result showed that Citrulluslanatus and Persea Americana seeds extracts significantly and progressively lowered the glucose level, TC, TGs and LDL dose dependently while significantly causing a dose-related elevation in HDL concentration. The result shows that atorvastatin and the seeds extracts are capable of reducing risk of AI, CRI and CVRI in diabetic rats

Earth Observation System-Based Impact Assessment of 2012 Flood in Delta State Nigeria

Flooding is one of the most serious natural hazards in the world. It has become a common natural disaster which has claimed many lives, displaced millions and resulted to the destruction of properties and degradation of contiguous farmland.  Though over the decades the people of Delta state have had to contend with sporadic overflows from the river but not in the scale of 2012 flood event. Flood in 2012, submerged coastal villages, displaced millions of people, submerged several square kilometers of land,  disrupt economic activities and properties worth of millions of naira was lost. This study was provoked based on the fact that since the disaster, no reliable investigation and inventory has been made as a guide for mitigation for future occurrence. Currently Earth observing system (EOS) is gaining popularity in solving many environmental problems due to its accurate and timely delivery of information required for decision making. Therefore the aim of this study was to determine the impact of 2012 flood in delta state.  Pre-flood and flood imageries captured by and Moderate Resolution Imaging Spectroradiometre (MODIS), Land sat imagery with resolution 30m, SRTM with resolution 30 arc second, questionnaire, interview, Global positioning system (GPS)  and geographic information system (GIS) was used for data collection and analysis. The map generated from the non-flood image captured on 20th October 2010 was used as a reference to determine the extent of flooding from the disaster image. Spatial impact was determined based on the extent of the submerged land territory while physical economic impact was measured based on property damages. This study revealed that a total landed area of 2185Sq.kms was covered by flood excluding the original extent of the river. Further assessment  revealed that 785000 people were affected, crops worth’s 3.1 billion naira were destroyed, 231 communities in 12 local government of the 25 local government areas were adversely affected these include 118 communities market, 743 market stalls, 220 primary schools, 84 secondary schools, 435 fish farms, 526 poultry farms, 58 piggeries and 5099 houses.

Serum CA125 and HE4 as Biomarkers for the Detection of Endometrial Cancer and Associated High-Risk Features

Early detection of endometrial cancer improves survival. Non-invasive diagnostic biomarkers would improve triage of symptomatic women for investigations. This study aimed to determine the diagnostic accuracy of serum Cancer Antigen 125 (CA125) and Human Epididymis 4 (HE4) for endometrial cancer and associated high-risk features. Serum samples from women investigated for gynaecological symptoms or diagnosed with endometrial cancer were analysed for CA125 and HE4. Conventional diagnostic metrics were calculated. In total, 755 women were included; 397 had endometrial cancer. Serum CA125 and HE4 were significantly elevated in cases compared with controls (both p < 0.001), and with pathological markers of disease severity (p < 0.05). A combination of CA125 and HE4 detected endometrial cancer with an area under the curve (AUC) of 0.77 (95% CI: 0.74–0.81). In a model with body mass index (BMI) and parity, HE4 predicted endometrial cancer in pre-menopausal women with an AUC of 0.91 [sensitivity = 84.5%, specificity = 80.9% (p < 0.001)]. In women with abnormal ultrasound, HE4 ≥ 77 pmol/L improved specificity compared with imaging alone [68.6% (95% CI: 75.0–83.6) vs. 34.4% (95% CI: 27.1–42.3), respectively], but at a cost to sensitivity. HE4 ≥ 77 pmol/L improved the detection of myometrial invasion ≥50% in women with stage I disease compared with magnetic resonance imaging (MRI) alone [sensitivity = 100% (95% CI: 54.1–100)]. CA125 ≥ 35 U/mL did not add to imaging. HE4 is a good predictor of poor prognostic features which could assist staging investigations
