IMPLEMENTATION OF HUMAN RESOURCE MANAGEMENT SYSTEM BASED ON CLOUD COMPUTING PRINCIPLES

ABSTRACT In other for a business/firm to get the best out of its employees and a high return on its investment in people, the human resources must be well managed. A good human resource management system brings consistency in human resource management practices and improves human relations in the company thereby enhancing individual/organizational effectiveness. With larger firms/organizations, it becomes increasingly difficult to manage a large number of human resources. Therefore,...

Multistage optimization in supply chain. Case study: WEMY industries LTD

LITERATURE REVIEW2.1 Optimization in supply chainIn literature, there is a considerable number of works in supply chain optimization, particularly for the minimization of duration and costs in the global supply chain on one hand, and for coordination between stages in supply chain on the other hand. In recent years, mathematical research in supply chain has developed many approaches and solutions. In the following sub sections, we present different works established in the field of optimizat...

PHYTOCHEMICAL AND ANTIMICROBIAL STUDIES OF VERNONIA PAUCIFLORA (Willd.)Less

Vernonia pauciflora is a plant found in the North central Nigeria and is used in the traditional treatment of many diseases includind Pneumonia, Tuberculosis, Skin infection, Meningitis, Whooping cough, Typhoid fever, Headache, skin infection, diarrhea. Phytochemical screening and antimicrobial studies were carried out on the aerial parts of the plant. The phytochemical screening was carried out using standard procedures and the antimicrobial activity was tested against pathogens using ...

Design and Implementation of a Micro Controller Based Traffic Light System for Road Intersection Control

ABSTRACT  The control of traffic at road junction, which was done purely by human effort, proves to be inefficient owing to the increasing rate  of both  motorists as well as the  complexity  of  road networks. This inadequacy brought about the use of discrete solid-state electronics up to the usage of a computer controlled microprocessor, but the intelligence of this method  was still limited   to   meet   the   deman...

ISOLATION, IDENTIFICATION AND ANTIBIOTIC SUSCEPTIBILITY OF Bacillus spp RECOVERED FROM THE HANDS OF APPARENTLY HEALTHY FEMALE UNDERGRADUATE STUDENTS OF OBAFEMI AWOLOWO UNIVERSITY, ILE-IFE.

ABSTRACTThe human hands harbour microorganisms both as part of a person’s normal microbial flora as well as transient microbes acquired from the environment. This study was carried out to isolate and identify Bacillus spp that are associated with the hands of apparently healthy female undergraduate students in Obafemi Awolowo University. The samples were collected using sterile swab sticks dampened into sterile 0.85% normal saline and processed immediately in the laboratory. The isolates we...

Quantitative Analysis of Carotene and Ascorbic acid from Carrot, Cucumber, Eggplant and Tomatoes

ABSTRACTSpectroscopic method was used to determine quantities of carotene and ascorbic acid in carrot, cucumber, eggplant and tomatoes. The result shows that carrot has higher concentration of carotene =0.1430, follow by eggplant = 0.6950 and tomatoes = 0.0368 and cucumber has the least concentration of carotene =0.0139. The result also show carrot has higher concentration of ascorbic acid 0.958×10-4 mol/d3 follow by tomatoes 0.944×10-4 mol/d3 and eggplant 0.943×10-4 mol/d3 cucumber 0.90...

Antioxidant Property of Coconut (Cocos nucifera) Water

ABSTRACTCoconut water is a natural nutritious beverage that contains several biologically active compounds. This study was set up to evaluate the antioxidant potential of coconut water. Twenty five adult male albino rats, used in this work, were grouped into five (A, B, C, D and E), of five rats per group. Groups A, B, C and D were administered orally with 0.5, 1.0, 1.5 and 2.0mg/kg body weight respectively of the coconut water for seven consecutive days. Group E was the control. Giutathione ...

Development and Implementation of a Disaster Management Centre

CHAPTER ONE1.0 INTRODUCTION "Disaster management" can be defined as the range of activities designed tomaintain control over disaster and emergency situations and to provide a framework forhelping at-risk persons to avoid or recover from the impact of the disaster. Disastermanagement deals with situations that occur prior to, during, and after the disaster.Globally, there has been lots of disaster on land, air and sea, though these disasters mayb...

COMPARATIVE ANALYSIS OF HEAVY METALS IN BRASSICA OLERACEA FROM KENYATTA MARKET, NAIROBI AND KAGOCHI, KARATINA

ABSTRACTVegetables has been an integral part of day to day diet for so many people in Kenya. It is used in the form of raw fruits, dried, powdered or cooked vegetables. This is a research that addresses this way of living to act as a precaution towards making the food healthier. It is with a significant concentration in Kenyatta market than Kagochi while chromium’s level was higher in Kagochi compared to Kenyatta market.From the above figures of heavy metals, it was conc...

LABORATORY REPORT ON THE DETERMINATION OF THE MOISTURE AND CLAY CONTENT OF GREEN SAND

The quality of castings in a green sand mould is influenced significantly by its properties, such as green compression strength, permeability, mould hardness, and others, which depend on input parameters. The relationships of these properties with the input parameters, like sand grain size and shape, binder, water, clay, etc. are complex in nature. The goal of this paper is to determine the green sand mould compressive strength in case of input parameters. A good moulding sand ...

PHYSIOCHEMICAL AND SENSORY PROPERTIES OF COOKIES PRODUCED FROM WHEAT, SORGHUM AND DEFATTED COCONUT FLOUR BLENDS.

ABSTRACTCookies were produced from wheat, sorghum, and defatted coconut flour blends to determine their potentials in cookie manufacture. Eight Cookies formulations were produced and they were evaluated for their proximate, physical, mineral, colour and sensory properties. The result showed that the moisture content ranges from 7.10 to 10.89%, ash content ranges from 0.88 to 1.15%, protein content ranges from 9.18 to 12.25%, crude fat ranges from 9.59 to 11.00%, crude fibre ranges from  ...

Gene frequencies of ABO and Rh blood groups in Nigeria: A review

Background: ABO and Rhesus factor (Rh) blood type are germane in human life in genetics and clinicalstudies.Aim of the study: The review was undertaken with the objective to provide data on the ABO and Rh(D)blood group distribution and gene frequency across Nigeria which is vital for blood transfusion and susceptibility to disease.Materials and methods: Literature search for ABO/Rh blood distribution in Nigeria was done and allele frequencies of A, B, O, D and d were calculated from the frequ...

APPLICATION OF DIFFERENTIAL TRANSFORM METHOD TO THE VIBRATION ANALYSIS OF SHEAR DEFORMABLE AFG BEAMS

The vibrations of axially functionally graded (AFG) beams are examined incorporating shear deformation and an imperfection. A coupled nonlinear model is developed in the Hamiltonian framework for an AFG imperfect beam. Different sources of displacement nonlinearities are involved in this problem, namely, the geometrical nonlinearities due to the large deformations, and the nonlinearities due to the presence of a geometrical imperfection along the length of the beam. Expressions for the virtua...
