Comparison of Different Properties of Paper and Pulp From Various Agrowaste Biomass ( Sugarcane bagasse, coir Fibre and maize stalks)

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 ...

Assessing University Research Governance Practices And Structures In Developing Countries: The Nigerian Universities’ Experience

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 ...

Interaction of Multiwalled Carbon Nanotube Produces Structural Alteration of DNA

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...

RELEASE KINETICS OF CYMBOPOGON CITRATUS ESSENTIAL OIL FROM STARCH BEADS

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 re...

CHARACTERISATION OF ESSENTIAL OIL FROM LEAVES OF Euphorbia heterophylla AND ITS INSECT REPELLENT POTENTIAL

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 an...

NATURAL WATER HARDNESS, POLLUTION, WATER CYCLE, TREATMENT AND USES

 PREFACEThe 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 CONTENTSTitle Page Dedication Acknowledgment Preface Table ...

Chemical composition and biological activity of Allium sativum essential oils against Callosobruchus maculatus

ABSTRACTIn order to search for alternative control methods to synthetic pesticides, the potential of essentialoils from Allium sativum (L.) (Alliaceae); was evaluated as fumigants against Callosobruchus maculatus (fab.)(Coleoptera: Bruchidae), a pest that attacks pulses during storage. Chickpea seeds were infested with 10 pairsof newly emerged weevils and, fumigated with 0, 1, 2, 3, or 4μl of essential oils of garlic/l of air. The essentialoils of garlic were analyzed by GC-MS. The major com...

PRINCIPLES OF CARBON-U (C-11) RADIO-CHEMISTRY

ABSTRACTCarbon –U (C-11) radiotracers are widely used for the early diagnosis of cancer, monitoring therapeutic response to cancer treatment and pharmacokinetic investigations of anticancer drugs. PET imagining permits non-invasive monitoring of metabolic processes and molecular targets, while carbon-II radiotracers allow a “hot-for cold” substitution of biological active molecules. Advance in organic synthetic chemistry and radiochemistry as well as improved automated techniques for ra...

The Role of Chemistry Teacher in the Development of Science Education in Nigeria

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 way...

CORROSION BEHAVIOUR OF METALS/ALLOYS WITH AND WITHOUT COATING AT HIGH TEMPERATURE (200 – 1000OC) AND UNDER MARINE ENVIRONMENT

INTRODUCTIONCorrosion is the deterioration a material undergoes as a result of its interaction with its surroundings. Although this definition is applicable to any type of material, it is usually reserved for metallic alloys. Of the 105 known chemical elements, approximately eighty are metals , and about half of these can be alloyed with other metals, giving rise to more than 40,000 different alloys. Each of the alloys will have different physical, chemical, and mechanical properties, but all...
