Evaluation of an improved inoculation technology using Bradyrhizobium japonicum USDA110 on peat and charcoal for the cultivation of soy bean plant

Nutrient paucity in the soil poses challenge to global production of food. The use of synthetic nitrogen fertilizers to boost crop yield is a recurrent farming practice, despite their unfavourable effects and hazard to the environment and human population. This study was aimed at developing an environmental friendly, low cost inoculation technology for the cultivation of soybeans. Laboratory approach was used in the production of the biofertilizer, which started with biochemical characterizat...

This research work is about computer based examination system. CHAPTER ONEINTRODUCTION1.1 BACKGROUND OF THE STUDY An Examination is one of the best methods of evaluating the knowledge andability of an individual. Its purpose is to assess how much each student haslearned compared to fellow students in the same course or learning situation.Various examination methods are being used in higher education institutions toassess   academic   progress,   such  &...

SYNTHESIS AND CHARACTERIZATION OF PYRIDYL BASED SCHIFF

Metal complexes are scientifically known to be active and effective as antibacterial, antivirus and some antifungal etc. This project work is targeted at preparing complex from transition metals say; cobalt, cupper, zinc and nickel and organic ligands synthesised from pyridyl based schiff bases, one from 2-aminopyridine and benzaldehyde and second from 2-aminopyridine and 2,4-dihydroxylbenzaldehyde. The analysis and completion is based on thin-layer chromatography, column-chromatography and I...

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)

Before the 1950s, logistics was thought of in military terms. It had to do with procurement, maintenance, and transportation of military facilities, material, and personnel. The study and practice of physical distribution and logistics emerged in the 1960s and 1970s. Logistics cost in the U.S. accounted for 15% of the gross national product and on an individual firm level, they could be as high as 32%. In the 1990s, a new name emerges: “supply chain management”. This name took the logisti...

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 ...
