The drying efficacy and product quality of onion and pepper dried in the oven and sun were compared. The drying process took 1-4 days to accomplish. The proximate analysis, bacterial load and identification of microorganisms, sugar fermentation, catalyses test and the bacteria count were determined. The mean moisture content of the product at the end of the drying was 6.4% (sun) and 4.5% (oven). The oven dried product were significantly (P
This paper addressed the popular issue of collinearity among explanatory variables in the context of a multiple linear regression analysis, and the parameter estimations of both the classical and the Bayesian approaches were compared using Mean Square Error (MSE) and Absolute bias. Five sample sizes: 10, 25, 50, 100 and 500 each replicated 1000 times were simulated using Monte Carlo method. Four degrees of correlation representing no correlation, weak correlation, moderate correlation and ...
The Aqueous, ethanol, hexane and ethyl acetate extracts of the leaves, bark and roots of Acacia albida, Anchomanes difformis, Boscia senegalensis, Bridelia ferruginea, Ficus ingens, Indigofera arrecta and Moringa oleifera were tested for possible source of antibacterial activities against selected clinical organisms found in the pediatrics hospital in Ondo and Ekiti State, Nigeria. The selected clinical organisms used for this research work are Salmonella typhi, Staphylococcus aureus, Klebsie...
It has been observed over the years that real life data are usually non-conforming to the classical linear regression assumptions. One of the stringent assumptions that is unlikely to hold in many applied settings is that of homoscedasticity. When homogenous variance in a normal regression model is not appropriate, invalid standard inference procedure may result from the improper estimation of standard error when the disturbance process in a regression model present heteroscedasticity. When...
The antimicrobial activities of the ethanolic, Aqueous and Ethyl acetate extracts of five Nigerian medicinal plant used as chewing sticks were tested against five microorganism, three bacteria and two fungi. The five medicinal plant tested are Vitellaria paradoxa, Vitex doniana, Sarcorcephalus latiolia, Vernonia amygdalina, Olax subcorpidica and the microorganisns are Staphylococcus aureus, Neisseria sieca, Streptococcus mutans and Lactobacillus salivarius and Actinomycetes viscosus. Out of t...
Bridelia ferruginea is commonly grown in Western Tropical Africa. The purpose of this research work is to determine the antimicrobial activities, qualitative and quantitative phytochemical screening, elemental composition, proximate analysis and anti-nutrient composition of purified fraction of Bridelia ferruginea extracts. The organisms used for this research are Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922, Klebsiella pneumonia ATCC 35659, Pseudomonas aeruginosaATCC 25619,a...
ABSTRACT Irradiation is a processing technology for improving the safety and quality by extending the shelf-life of food products. Effect of γ-irradiation (2, 4, 6, 8 and 10 kGy) on color, functional and pasting properties of flours and starches of five cultivars of rice was investigated. Color (L, a, and b) of non- and γ-irradiated rice cultivars was measured, and the deltachroma (DC), color difference (DE) and hue angle were calculated. Functional and physicochemical (pasting) of the mill...
Morinda lucida is a tropical West African evergreen shrub or small to medium sized rainforest tree, having brown colored bark, white flowers and yellowish ellipsoid seeds. It is widely used in traditional medicine systems of different countries. This study was designed to carry out the preliminary phytochemical screening and evaluation antioxidant and proximate properties of ethanol extracts prepared from the bark, leaves and root of M. lucida . It revealed the presence of saponin, tannins, a...
Erythrina senegalensis DC. (Coral tree) is commonly grown in West Africa as an ornamental plant and one of the oldest known African medicinal plants. The purpose of this research is to determine the antimicrobial potency, phytochemical activities, nutrients and elemental composition of the leaf and bark of Erythrina senegalensis. The organisms used for the study are Escherichia coli, staphylococcus aureus, Candida albicans and Klebsiella pneumonia. The leaf and bark were extracted using one e...
Daniella oliveri (Caesalpiniacea) is a plant found in the Amazon region and other parts of South America and Africa. The tree may reach a height of 100 feet and trunk diameter of 4 feet. Daniella oliveri (Rolfe) Fabiaceae is commonly known as Ilorin balsam (eepo-iya) or Copaihu africana . It is an indigenous African tree, found extensively in Benin, Cameroon, Gambia and Nigeria. The basic objective of this project is to determine the antimicrobial activity and phytochemical composition of Dan...
The plant Morinda lucida falls under the family Rubiaceae known to have wide usage in traditional medicine. Morinda lucida is a tropical West African tree of medium-size about 18–25 m tall, the bark is grey to brown in colour, flowers are white in colour, the fruit is a drupe, seed is ellipsoid, yellowish and soft. The purpose of this work is to determine the antimicrobial properties of Morinda lucida against Mycobacterium species, a very virulent and infectious organism, isolated ...
Morinda lucida is a tropical West African tree of medium-size, having brown colored bark, white flowers and yellowish ellipsoid seeds. It is widely used in traditional medicine systems of different countries. The preliminary phytochemical screening of different extracts prepared from bark, leaves and seeds of M. lucida revealed the presence of Saponin, Tannins, Alkaloids, Flavonoids, and Cardiac glucosides. Furthermore, it also reveals presence of Minerals like Sodium, Potassium, Calcium, Iro...
ABSTRACT The most amazing feature of Earth is the existence of life, and the most extraordinary feature of life is its diversity. Human beings can coexist only with the abundance of and diversity of nature. It is widely acknowledged that biodiversity underpins ecosystem functioning and that the provisioning of ecosystem services is essential for human well-being. The relationship between biodiversity and ecosystem services is not straightforward, whether more biodiversity would imply more ...
ABSTRACT: The earth has three layers each consisting solid materials that make them hard and difficult to be penetrated. But, suppose we neglect every other hindrances, where do we expect to go when we dig straight down through the earth passing through all the layers. This paper explains all about what is experienced and the Scientific analysis when/if the earth where to be dug through.
