ANALYTICAL STUDY ON THE OPTIMIZATION OF CROP NUTRIENTS USING THE RANDOMIZED COMPLETE BLOCK DESIGN MODE

AbstractThis 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&...

An_Assessment_of_the_Impact_of_Selected_Demographic_Characteristics_on_Fertility_Differentials

AbstractThe 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 urb...

A_STUDY_ON_APPLICATION_OF_ACCEPTANCE_SAMPLING_PLAN_IN_PROCESSING_CONTROL_AND_MONITORING

AbstractThis 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 consume...

THE EFFECT OF DIFFERENT SUBSTRATES ON THE PHENOTYPE, NUTRITIONAL, PHYTOCHEMICAL COMPOSITION AND ANTIOXIDANT ACTIVITY OF PLEUROTUS PULMONARIUS

                                                                              ABSTRACTMushroom 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 a...

Nanotechnology and its Place in Modern Medicine

                                                                                   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 appro...

Biochemical role of antioxidants in the living system

INTRODUCTIONOxygen 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 th...

SYNTHESIS AND CHARACTERIZATION OF ECO- FRIENDLY UREA-FORMALDEHYDE COMPOSITES BASED ON NATURAL CELLULOSE FIBER

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 reinforcement, ...

Properties of urea-formaldehyde-resin-cellulose composites

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 Formaldehyd...

Eco-friendly Urea-Formaldehyde Composites Based on Natural Cellulose Fiber

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...

APPLICATION OF PSYCHROPHYLIC ENZYMES IN BIOTECHNOLOGY

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 ...
