Abstract: This study investigated the presence of polycyclic aromatic hydrocarbons (PAHs) in the different cooking methods of chicken. The levels of 16 PAHs compound were determined in raw and cooked chicken meats. The chicken was cooked with different methods, i.e. boiling, frying, barbequing and roasting. The uncooked sample served as the reference. With the aid of the 16 PAHs reference standards, the levels of the PAHs were determined using gas chromatography - flame ionization detector (...
ABSTRACT An increased concern in recent times has been the effect of industrial effluent discharge into the water bodies. Surface water samples of Ibeshe River were studied to find out the pollution load of wastewater generated from the textile industry and its impact on the quality of the receiving river. Water samples were collected at four (4) different points for each of the three (3) steam divisions (the upstream, the midstream and the downstream) bimonthly within one year; 3 months rep...
Abstract Soil contamination with heavy metal due to discharge of untreated or incompletely treated industrial effluent is a threat to the ecosystem and human well-being. The effect of textile waste effluent on four vegetable plants (Corchorous olitorius, Telfairia occidentalis, Celosia argentea and Amaranthus hybridus) cultivated within farmlands located along the Abuja River in Ibeshe town near Ikorodu, Lagos State was investigated. Their heavy metal levels were determined using atomic abso...

Abstract This paper attempts to evaluate the application of randomized complete block design (RCBD) model in improving crop production. Data for the study was sourced from an experiment that lasted for three weeks. The data were analyzed using SPSS package. After exploring the concept of the RCBD technique, the response of the soil nutrient to the treatment of the various manure types revealed that, there was a significant difference on crop yield with respect to the type of manure tre...
Abstract The current fertility rate(FR) reporting in developing and under developed countries of the globe has drawn the attention of national and demographic planners in seeking for solution to reduce the population growth and its attendant global consequences. It is in this light that this study seeks to determine some significant demographic characterization responsible for influencing fertility behavior and differentials. Using a random sample of 570 mothers both from a rural and urban e...
Abstract This study examined the use of acceptance sampling technique as an efficient tool for quality assurance in deciding whether a given lot of product is to be accepted or rejected in the market. This study designed two single sampling plans with a sample size of 125 from a lot of size 1350 bread loaves and an allowable number of defectives as 4 and 6 (i.e. c=4 and 6). The result indicated that the probability of rejecting the manufacturers’ product of good quality by the consumers is...
ABSTRACT Mushroom has been an important food to man for millennia. Several species of Pleurotus has been cultivated successfully on different substrates including Palm bunch, Saw dust and Corn cob. Pleurotus pulmonarius has also been cultivated but there is a gap in knowledge as to the effect of different substrates on the phenotypic, nutritional, phytochemical and antioxidant ...
AbstractNanotechnology is the study and application of extremely minute structures known as nanomaterials. These nanomaterials have sizes ranging from 0.1-100nm. Nanomaterials are produced using two approaches which are the bottom up approach and the top down approach and have been applied to various fields including medicine. The application of nanotechnology in medicine is known as nanomedicine. Nanomaterials such as liposomes, dendrimers, and quantum dots have been applied in disease diagn...
INTRODUCTION Oxygen is an indispensable element for life. Oxidative property of oxygen plays a vital role in various biological phenomena; being essential for life, oxygen can also aggravate the damage within the cell by oxidative events. Oxygen is used by the cell to generate energy and free radicals are formed as a consequence of ATP (adenosine triphosphate) production by the mitochondria. Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are the by-products resulting from t...
i have collected data and have tried to write a paper.
Cellulose is the most common structural biological organic compound on Earth which is widely used in paper and textile industries and urea-formaldehyde resin is a thermosetting plastic used mostly as adhesives for plywood, particleboard and other structured wood products. Natural fiber composites are realistic alternatives of glass fiber composites. Using urea-formaldehyde, resorcinol-formaldehyde, phenol-formaldehyde, saturated polyesters as matrixes and natural fiber as reinforcem...
Cellulose is the most abundant, structural, biological organic compound on Earth which is widely used in paper and textile industries. In this project work, the blend of compressive character of Urea-Formaldehyde Resin with addition of Cellulose is tested. Cellulose can be extracted from dried plant by alkaline treatment (mercerization), followed by neutralization with acid; product of which undergoes bleaching to produce pure form of cellulose. Urea Formaldehyde Resin c...
The variation of character of urea formaldehyde resin with addition of cellulose extracted from corn husk was tested. Cellulose was extracted from dried raw corn (Zea mays) husk, the second largest agricultural crop grown around the world, by alkaline treatment (mercerization), followed by neutralization with acid; product of which underwent bleaching to produce pure form of cellulose. Urea-formaldehyde (UF) resin was prepared by heating the formaldehyde in paraffin oil bath and adding urea t...
Psychrophilic enzymes are biocatalysts that control biochemical processes at low temperatures by either accelerating or decreasing the reaction rate. These enzymes are mainly obtained from microorganisms which inhabit cold environments and proliferate at low temperatures. The cold-loving organisms referred to as psychrophiles are adapted to the extreme cold conditions which resulted in changes in their biochemical machineries such as their enzymes. This resulted in certain characteristics of ...
