An In Vitro Study Of The Antibacterial Properties Of Selected Plant Species Found In Adamawa State, Nigeria

ABSTRACT The antibacterial activity of plant extracts compared to a known antibiotic (ampicillin) was evaluated against ten gram-negative and gram-positive bacteria which can infect humans. In addition, the efficacies of different extraction methods were studied. Soxhlet, cold aqueous, and hot aqueous extractions were used in this study. Moreover, extracts from the following plants were utilized: Zingiber officinale (ginger); and the leaves of Agave americana (agave), Musa acuminata (banana)...

Characterization Of Wild Yeast Strains From North Eastern Nigeria For Bioethanol Production

ABSTRACT This purpose of this experiment was to characterize wild strains of yeasts from different sources from north eastern Nigeria that have unique traits that will be applicable in the bioethanol production industry. The yeast characterization of these yeast strains were based on the yeast strain ability to grow at different temperature conditions, their ability to grow in various pH condition and their ability ferment different sugars. 10 yeast strains were tested. These yeast strains w...

Assesment Of Bacteria Found In The American University Of Nigeria (AUN) Facilities And Potential Health Impacts

ABSTRACT Globally, human health is under threat due to the presence of diseases caused by microorganisms such as bacteria and viruses. Bacteria are found on almost all surfaces with which people come into contact and therefore pose a threat to human health. Antimicrobial resistance is a major health concern as these microorganisms can cause untreatable diseases. I tested the surfaces found in three buildings on the campus of the American University of Nigeria in Yola, Adamawa State, for the ...

Analysis Of The Knowledge And Perception Towards Down Syndrome In Adamawa State

The research also tried to ascertain the knowledge of these parents about the disorder before and after the birth of their children. If they had more than one child with Down syndrome was...

A Comparative Study On The Corrosion Of Stainless Steel In 1m Hydrochloric Acid Using Tamarindus Indica (Tamarind) And Terminalia Catappa (Tropical Almond) Leaves Extracts As Inhibitors

ABSTRACT The effectiveness of Terminalia catappa (tropical almond) and Tamarindus indica (tamarind) as corrosion inhibitors for stainless steel in 1M hydrochloric acid at 30°C, 40°C and 50°C was investigated in this research. The gravimetric method of analysis was employed for 20 days at a 4-day interval using 0.9, 1.1 and 1.3g/15mL of Terminalia catappa leaves extracts and 1.4 and 2.3g/15mL of Tamarindus indica leaves extracts. The results showed that the two extracts acted as good inhib...

Sustainability Analysis And Improvement Plan For The American University Of Nigeria Food Service.

ABSTRACT Analysis of data to determine how much knowledge the American University of Nigeria food service has on sustainability as well as creating an improvement plan has formed the crux of this research paper. The American University of Nigeria has been able to provide and implement sustainability plans however these plans do not include the food service. To help determine what level of improvement is required, interviews were done, periodic visits and observations were also done. It would...

Orange Juice Bottling Company, Owerri, Imo State. (Enhancing Fu Nctioualiry Through Circulation And Safety)

ABSTRACT Research has shown that the popularization of plastic bottles in Bottling Industries has remained on the increase since middle of 1960's, when high-density polyethylene was introduced. They quickly became popular with both manufacturers and customers due to their lightweight nature and relatively low production costs compared with glass bottles. Except for wine or beer, the food industry has almost completely replaced glass with plastic bottles. Despite this innovation, there has con...

Quantifying Rate Of Vegetation Cover Changes In Enugu State Using Ndvi Techniques For The Year 1991, 2003 And 2015

ABSTRACT This project examines the rate of vegetation cover changes in Enugu State using NDVI techniques for the year 1991, 2003 and 2015 so as to detect changes that has taken place between these periods. The main goal of this study is to evaluate vegetation cover change of the study area using Normalized Vegetation Index (NDVI) in order to identify vegetation cover and the spatial distribution in the area for the period of investigation and to produce NDVI and spatio-temporal change maps a...

Evaluation of The Toxicity And Anthelminthic Effect of Methanol Extract of Duranta erecta Fruits

ABSTRACT The chemotherapy of gastrointestinal helminthiasis relies mainly on the use of anthelmintics. However, concerns over drug resistance have encouraged the search for new drug leads. This project report focused on evaluating the toxicity and anthelminthic effect produced in vitro and in vivo by the methanol extract of Duranta erecta fruits. From the study, the plant extract was found to contain several chemical components including flavonoids, tannins, polyuronides, saponins, glycoside...

Determination of The Concentration of Pollutants From Warri Refinery Effluent And its Impact on Water Quality of Ubeji River

Abstract This study investigated the effects of effluent discharged from Warri Refinery on the water quality of Ubeji River, Warri Delta state. Water samples were collected from upstream, point of discharge of effluent and downstream sections of the river. Physicochemical parameters (turbidity, pH, electrical conductivity, total dissolved solid, total suspended solid, turbidity, dissolved oxygen, biological oxygen demand, chemical oxygen demand, oil and grease), concentrations of polycyclic ...

Unfortunately, the state and its capital in particular lacks Boat Terminal infrastructure. Apart from this fact and the actual trip was undertaken, other diverse and complex requirements of travellers must be adequate, considered and tackled. The imp importance of public transit sy...

Finite Element Assessment of Precast Concrete Slab Using Ansys Structural

ABSTRACT Concrete is used widely in all types of construction. In particular, it is the first choice material for the construction of various industries, due to its affordability, durability, heat resistance, strength, etc. Based on this, understanding the response of concrete structural components for all types of loading is crucial to the development of an overall safe and efficient structure. Various methods have been used to study the response of concrete structural components to various...
