INCIDENCE AND PREVALENCE OF HEPATITIS C AMONG OUTPATIENTS IN SOME SELECTED HOSPITALS

ABSTRACTHepatitis C virus (HCV) is a meticulous factor of liver disease and one of the most important health issues worldwide. Hepatitis is the inflammation of the liver produced by autoimmune disease, alcohol or drug abuse, genetic disorder or microbial infection. To detect the presence; prevalence; incidence; and the relationship between the different risk factors of hepatitis C among patients in Ilorin. This study reports on the occurrence of Hepatitis C Virus (HCV) antibodies among ...

Automotive crash detection and airbag deployment using MEMS accelerometer1

This paper aims to have a brief study on the operation of an airbag deployment system usingdifferent sensors. Automobile airbag has gained acceptance over the years as an effectivemeasure to reduce the morbidity and mortality associated with motor vehicle accidents, as such more vehicles have become equipped with them.As noble as the idea sounds new problems have been encountered with the deployment system and its relative sensors which have led to the following injuries retinal damage...

Phytochemical and Antimicrobial Properties of Lavandula angustifolia

Abstract: This present study deals with the quantitative and qualitative phytochemical screening, the antimicrobial properties and thin layer chromatography of Lavandulaangustifolia leaves extracts. These were achieved using the cold maceration method of extraction involving hexane, water (aqueous) and ethanol, to ensure that a wide polarity range of components are extracted. Alkaloid, phenol, flavonoids, tannins, terpenes, glycosides and steroids were observed present in the leaves extra...

Quantum chemical calculations on SiF4 and it's protonated analogues

Abstract: For every heteronuclear molecule, protonation can occur at more than one site thus giving rise to more than one proton affinity. Experimentally, only one proton affinity (PA) value is reported for a molecule and the experiment does not specify the site for the protonation. In the present work, quantum chemical calculations are carried out on SiF4 and its possible protonated analogues (HF4Si+ and HSiF4+) by employing several computational chemistry methods in...

THE ROLE OF LIBRARY COMMITTEE IN THE DEVELOPMENT OF ACADEMIC LIBRARIES

1.0 INTRODUCTIONLibrary Committees play a critical role in the development of academic libraries. It is, therefore, a standard practice for every academic library to have a Library Committee. These Committees are expected to be functional and vibrant thus performing advisory, regulatory, selection and de-selection, policy-formulating, and other decision-making roles. The Committees should have the powers to take far-reaching decisions regarding the development of the Academic Libraries...

The Society for Environmental Geochemistry and Health (SEGH): building for the future

SEGH has been a welcoming society for early career researchers (ECRs) over the years, providing a supportive and encouraging atmosphere at conferences. However, a formal structure was required to continue to engage and support ECRs as they become established in their careers. In addition, retention and recognition of experienced scientists and practitioners were required for past and ongoing contributions to the long-standing success of SEGH since the initial formation in the early 1...

Comparative Study on the Influence of Grilling Height on the Concentration of Polycyclic Aromatic Hydrocarbons (PAHS) and Some Toxic Metals in Grilled Foods

Abstract:A comparative study was carried out on the effect of grilling height on the extent of accumulation of the 16 US EPA priority PAHs and some volatile (As and Hg) and non-volatile (Mn, Cu, Pb, Cr, Cd and Ni) heavy metals in two kinds of roasted foods; yam (Dioscorea Rotundata ) and plantain (Musa Paradisiaca) commonly consumed in Nigeria. Yam and two variants of plantain (unripe and ripe) were considered for this study. Two grilling heights (10 cm and 20 cm) were employed on each of ...

Impact of Cooking Methods on the Levels of Polycyclic Aromatic Hydrocarbons (PAHs) in Chicken Meat

Abstract: This study investigated the presence of polycyclic aromatic hydrocarbons (PAHs) in the different cooking methods of chicken. The levels of 16 PAHs compound were determined in raw and cooked chicken meats. The chicken was cooked with different methods, i.e. boiling, frying, barbequing and roasting. The uncooked sample served as the reference. With the aid of the 16 PAHs reference standards, the levels of the PAHs were determined using gas chromatography - flame ionization detecto...

Assessment of Surface Water Contamination and Effect of Textile Effluents on Ibeshe River, Ikorodu, Lagos State, Nigeria

ABSTRACT An increased concern in recent times has been the effect of industrial effluent discharge into the water bodies. Surface water samples of Ibeshe River were studied to find out the pollution load of wastewater generated from the textile industry and its impact on the quality of the receiving river. Water samples were collected at four (4) different points for each of the three (3) steam divisions (the upstream, the midstream and the downstream) bimonthly within one year; 3 months ...

Impact of Textile Wastewater on Whole Plants of Corchorous olitorius, Telfairia occidentalis, Celosia argentea and Amaranthus hybridus Cultivated within Farmlands in Ibeshe, Ikorodu, Lagos St

Abstract Soil contamination with heavy metal due to discharge of untreated or incompletely treated industrial effluent is a threat to the ecosystem and human well-being. The effect of textile waste effluent on four vegetable plants (Corchorous olitorius, Telfairia occidentalis, Celosia argentea and Amaranthus hybridus) cultivated within farmlands located along the Abuja River in Ibeshe town near Ikorodu, Lagos State was investigated. Their heavy metal levels were determined using atomic a...
