Isolation and Sensitivity of Bacteria Isolate from Vaginal Discharge to Antibiotics

ABSTRACT Normal vaginal flora contains a wide range of microorganisms. Bacterial vaginosis BV is the main reason for vaginal discharge. Many gram-positive and gram-negative rods i.e. E.coli, Klebsiella, Proteus, Acinetobacter and Pseudomonas spp. are major contributors to bacterial vaginosis. Aim: The present study was conducted to elucidate the frequency of various bacteria in high vaginal swabs and the sensitivity pattern of bacteria to antibiotics that are currently used Material and Metho...

Phenotypic Detection of Extended Spectrum Beta Lactamases Producing Organism Among Godfrey Okoye University Students

ABSTRACT Extended-spectrum beta-lactamases (ESBL) are enzymes that confer resistance to most beta-lactam antibiotics, including penicillin, cephalosporin, and the aztreonams. The aim of this present study is to phenotypically identify and establish the presence of ESBL-producing organism among students in the university community. Within the University community of Godfrey Okoye University, Enugu, early morning urine samples of midstream-catch were collected into sterile bottles from sixty (6...

Comparative Study of the House Rent a Case Study of Gw Agw Alada and Kw Ali Area Councils

CHAPTER ONE 1.0 Introduction 1.1 Background of the Study Housing is one of the 3 most significant in the sustainability of human existence with considerable economic, social, cultural and personal importance. The production of housing has been influenced largely by policies, innovation and the ability to sustain the environment. Housing in today's parlance has become amulet-dimensional bundle of services, encompassing the need for privacy, aesthetic value, and conformity to statutory standar...

Comparative Study of Autoregressive Integrated Moving Average and Artificial Neural Network Models in Forecasting Food Prices

ABSTRACT  Prices of food are known to be a good indicator of food security and knowledge of their future value cannot be overemphasized. Box-Jenkins ARIMA model is a frequently used approach in forecqsting time series. However, recent researches suggest that Artificial Neural Network (ANN) model can be a good alternative to the conventional use of ARIMA model. This study seeks to examine and compare the forecast efficiency of ARIMA and ANN models for data on food prices in Nigeria. The A...

A MODEL OF NEUTRINO MASSES: GRAVITY-EMBEDDED WEINBERG OPERATOR

This paper investigates the propagation of neutrinos in a curved spacetime background. Following from this, we propose a novel mechanism for generating their masses via gravity-embedded Weinberg operator. This model arises from a hitherto unexplored interaction between gravitational field and the Majorana-neutrino fields. Two distinct methods, each, of calculating dimensionless gravitational couplings from a  gravitational field and spontaneous-symmetry-breaking mass-scale  of hi...

Studies On Possible Beneficial Biochemical Outcomes of Single and Combinatorial Herbal Formulations On Diabetic Wistar Rats

ABSTRACT Medicinal plants continue to provide valuable therapeutic recipes, in orthodox and traditional healing systems, for the amelioration of diseases and disorders. The current study sought to evaluate the capacities of single herbal formulations (SHFs), double herbal formulations (DHFs), triple herbal formulations (this) and quadruple herbal formulation (QHF) of leaf extracts of Acanthus Montanus, Asystasia gangetica, Gongronema latifolium and Solanum melongena to ameliorate hyperglycem...

Chemo protective Effect of Methanol Leaf Extract of Picralima Nitida On Carbon Tetrachloride-Induced Oxidative Stress in Albino Rats

ABSTRACT Among medicinal plants, Picralima nitida is well investigated and has been shown to possess renal and hepatoprotective activities. The present study was conducted to investigate the chemoprotective effect of methanol extract of Picralima nitida leaves on carbon tetrachloride-induced oxidative stress in albino rats. Thirty (30) Wistar albino rats of six (6) rats per group were used for this study and were divided into 5 groups. Group 1 rats were normal control; group 2 (negative contr...

Chemical Evaluation and Remediation of Petroleum Sludge Impacted Soils from Itsekiri Communities Around Warri Refinery in Delta State, Nigeria

ABSTRACT Petroleum sludge samples from Warri Refinery and Petrochemical Company (WRPC), Delta State, Nigeria and soil samples from five selected oil-impacted communities (Ubeji- 500 m, Ekpan- 1 .5 km, Aja-Etan - 2.5 km, Ifie-Kporo - 3.0 km, ljala-Ikenren - 3.8 km from WRPC) around WRPC were collected and analyzed to appraise the levels of total petroleum hydrocarbons (TPH), Polycyclic aromatic hydrocarbons (PAH), and heavy metals (Cr, Cd, Pb, Ni, Cu, Co, Mn, Fe and Zn) caused by the petroleu...

Chemical Contents and Characterization of the Biologically Active Compounds of Nigella Sativa Linn. (Ranunculaceae) Seeds

ABSTRACT The seed of Nigella sativa was evaluated for its chemical composition, medicinal as well as its nutritional values. The powdered seed was extracted with methanol to give the crude extract. Phytochemical screening of the crude extract revealed the presence of the following classes of natural products; alkaloids, tannins, flavonoids, saponins and anthraquinones, sterols and terpenes. The proximate analysis showed 12.00% moisture, ash content 3.00%, ether soluble extract 33.30% crude p...

Chemical and Microbial Assessment of Ground and ·Surface Water Quality in Bwari Area Council, Abuja

ABSTRACT The Chemical and miCrobial assessment of water quality was investigated with a view to obtain a qualitative and quantitative information on the state of drinking water in Bwari Area Council of Abuja., which. is known for its poor sanitary conditions. Samples of water were collected from boreholes., wells and stream from selected sites and analyzed using standard methods of water analysis. The test result showed higher levels of Mn., Zn, Fe., and Ni in both ground and surface water.,...

Studies On Biogas and Bio Liquid Production by Fungal Degradation of Banana (Musa Sapientum) Leaves

Abstract Anaerobic biodegradation of banana leaves by cellulolytic fungus (yeast) was conducted at optimum operational conditions of concentration, temperature and pH for biogas and bio liquid production. Proximate analysis of both the fermented and unfermented substrates was carried out. Effects of nutritive additives on biogas and bio liquid production were investigated. The bio liquid generated was extracted by soxhlet extraction and, its components were separated into maltenes (soluble c...

Biochemical Effect of Ethanol Leaf Extract of Mucuna utilis on Lead Acetate Induced Toxicity on Wistar Albino Rats

ABSTRACT This study investigated the effect of ethanol leaf extract of Mucuna utilis (EEMu) on lead acetate induced toxicity on Wistar albino rats. Acute toxicity analysis of the plant extract produced no lethality even at high doses of 3000 mg/kg body weight. Twenty albino rats weighing 115 – 235 g were divided into four (4) groups; the first groupof animals served as normal control and were not administered either lead acetate or EEMU. The second group was treated intraperitoneally with l...

Combinatorial Properties of the Alternating & Dihedral Groups and Homomorphic Images of Fibonacci Groups

Abstract Let Xn = { } 1,2,…,n be a finite n -element set and let Sn An and Dn , be the Symmetric, Alternating and Dihedral groups of Xn , respectively. In this thesis we obtained and discussed formulae for the number of even and odd permutations (of an n − element set) having exactly k fixed points in the alternating group and the generating functions for the fixed points. Further, we give two different proofs of the number of even and odd permutations (of an n − element set) having ex...
