Abstract People usually think food processing bring about reduction in food nutrients as well as the quantity because few quantities must have been lost or wasted during processing, many said food processing affect the taste and color of the food when compared to its whole form. Meanwhile, food processing which also includes its preparation makes food last longer than when in its whole form (increases its shelf life), although its positive effects are numerous but its negative effects canno...
Drinking water quality was investigated at Daranna community the mineral rich part of Kaoje town in Kebbi state, to ensure the continuous supply of clean and safe drinking water for the public health protection. In this regard, a physical and chemical analysis of drinking water samples was carried out for samples collected at different locations within the community areas. A number of parameters such as colour, temperature, pH, electric conductivity, dissolved oxygen, total hardness, COD, ...
The goal of this research was the discovery of newer anti-inflammatory drug. Four hydrazones with p-nitrophenyl moiety were synthesized by solvent-free and conventional synthetic methods with good to excellent yields. The synthesized hydrazones were evaluated for their anti-inflammatory activities using carrageenan-induced paw edema in mice. All the compounds indicated significant anti-inflammatory activity, demonstrating slow onset of action and longer duration of action compared to celecoxi...
The preliminary screening of phytochemical constituents of extracts of Xylopia aethiopica was evaluated. The n-hexane extract revealedthe presence of terpenoids, alkaloids, and steroids, while the presence of alkaloids, terpenoids, saponins, steroids, and phenolics was indicated in ethyl acetate extract, and the methanol extract contained tannins, flavonoids, phenolics, terpenoids, saponins, alkaloids, steroids. The medicinal property of the extracts was investigated using in-vitro antimicrob...
We designed novel p-nitrophenyl hydrazones as multi-target inhibitors of COX-2, 5-LOX, and H+/K+ ATPase in a bid to overcome side effects associated to NSAIDs and coxibs. Specifically, compounds 1-(4-nitrophenyl)-2-[(3,4,5-trimethoxyphenyl)methylidene] hydrazine (3), 4-hydroxy-2-methyl-6-[(2-(4-nitrophenyl)hydraz-1-ylidene)methyl]thiochroman-1,1-dioxide (6), 4-methoxy-2-methyl-6-[(2-(4-nitrophenyl)hydraz-1-ylidene)methyl]thiochroman-1,1-dioxide (8), 2-methyl-6-[(2-(4-nitrophenyl)hydraz-1-ylid...
The pyridyl based Schiff base ligands from 2-aminopyridine and benzaldehyde and 2-aminopyridine and 2, 4-dihydroxylbenzaldehyde were synthesized by: 1. For Schiff base from 2-aminopyridine and benzaldehyde; Distillation of Benzaldeyde to ensure maximum purity from possible contaminant like water and ammonia, and refluxed with freshly prepared 2-aminopyridine. The refluxing was done with ethanoic acid catalyst at a time and without catalyst. The process was followed up with Thin Layer Chromato...
This study presents the comparison of various properties of paperboard from various Argo wastes. The agro wastes under study in this project include sugarcane bagasse, coir fiber (coconut husk) and maize stalk. The properties differ as a result of the composition and structure of the biomass that is put into consideration that is the amount of cellulose, hemicellulose and lignin available in the agro waste biomass. Paper is basically made from cellulose fibers therefore the project aims to di...
ABSTRACT: In this study, the oil extracts from fresh and dried peels of Cleopatra mandarin were isolated and characterized via GC-MS technique. Also the study established both quantitative and qualitative variation in chemical constituents of the essential oils of Cleopatra mandarin (L) cultivated in the North central of Nigeria. Fresh and dried pulverized peels of Cleopatra mandarin (500g) were separately hydro distilled and afforded oil in the range 0.2- 0.8%(w/w) respectively. GC/MS...
ABSTRACT While most universities in the developed world, by tradition, have research offices to handle research management, structures for the efficient coordination and strong governance of research are nascent within many Sub-Saharan African universities. In this paper we look at the organizational structures, policies and functions of research offices for supporting faculty research as well as their management operations in 5 selected Nigerian universities. The authors interviewed 20 part...
ABSTRACT Multiwalled carbon nanotube (MWCNT) has been found to produce structural changes in Calf Thymus-DNA (CT-DNA). The interaction or binding of the multi-walled carbon nanotubes (MWCNT) was investigated in order to discover if it brings about any significant changes of the DNA double helix using CD spectra of the CT-DNA at two concentration levels of MWCNT representing an increasing MWCNT/DNA molar ratio. In addition, spectrophotometric titrations between MWCNT and CTDNA were carried ou...
ABSTRACT The essential oil of Cymbopogon citratus was extracted using a green method (i.e. essential oil still), encapsulated into cassava starch matrix using sodium alginate as a binder. The encapsulated sodium alginate starch beads were characterized using Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectrophotometer (FTIR), release kinetics of the oil was monitored by UV-Visible Spectrophotometry from two (2) aqueous media, buffer of pH 4 and pH 9. The result for ...
This study aimed at characterizing essential oil from leaves of E.heterophylla and its insect repellent potential. Essential oil from fresh leaves of E.heterophylla was extracted by hydro distillation method, using a Clevenger apparatus for 4 hours and the yield was 0.1816%w/w. Repellence test was conducted by using 5 cockroaches in number which were placed in a modified Y-tube Olfactometer and observations recorded for each and every odour introduced after 5 minutes i...
PREFACE The concept of Natural Water Hardness has been a subject of much discussion since the exception of the natural science unit. It borders on the sources of water hardness, types of hard water and effects of hard water. Pollution on the other hand is an environmental problem which needs to be tackled. This term paper writes more on it. Water cycle, treatment and uses are also discussed in the term paper. TABLE OF CONTENTS Title Page Dedication Acknowledgment Preface Table of ...

AbstractThis work titled The Role of Chemistry Teacher in the Development of Science Education in Nigeria is specifically designed to find out and discuss the various ways science education has been lagging in Nigeria and how chemistry education can help to remedy the situation. In the course of this, some issues were discussed such as the concept of chemistry, chemistry education, science education, objectives of chemistry education, problems facing science education in Nigeria and ways to...
