MYCOTOXINS AND ITS EFFECTS

  ABSTRACT color:black;mso-themecolor:text1"> Mycotoxinsare secondary metabolites of molds that have adverse effects on humans,animals, and crops that result in illnesses and economic losses. Aflatoxins,ochratoxins, trichothecenes, zearalenone, fumonisins are the mycotoxins ofgreatest agro-economic importance. Some molds are capable of producing morethan one mycotoxin and some mycotoxins are produced by more than one fungalspecies. Often more than one mycotoxin is found on a contamina...

AN ASSESSMENT ON THE ACTIVITIES OF FRAUDSTERS USING ATM PIN

ABSTRACT   The use of ATM has grown rapidly in popularity because of its low banks transaction  costs and customers convenience which has made it a basic element of today’s financial service delivery. However, the ATM which is meant to be serving the customers better is now becoming a nightmare for some customers because of fraud perpetuated in their accounts through ATM withdrawals. The main purpose of this work is to examine the activities of fraudsters through ATM pin and how these fr...

ICT as antidote in learning difficulty in chemistry at senior secondary school level

ABSTRACT This study investigated the use of information and communication technology (ICT) as antidote in learning difficulty in chemistry in Ilesa-East L.G.A of Osun state. 100 students and 30 teachers were randomly selected for the study. The instruments used for collecting information were teachers’ and students’ questionnaires. Data collected were analyzed using Chi-square statistic. The results revealed that: 1. There is a significant difference between teaching guide in chemistry...

ANTIMICROBIAL ACTIVITIES OF MANGO PEEL AGAINST SOME PATHOGENIC ORGANISMS.

ABSTRACT Antimicrobial activity of ethanolic extract of Mangifera indica peel was tested on some pathogenic organisms. The extract was tested for activity against, Baciollus subtilis, Staphylococcus aureus, Escherichia coli, Salmonela typhii, Pseudomonas notatum and Aspergillus fumigates. The extract exhibited activity against the organisms in varying degrees. In agar diffusion test, Escherichia coli showed the highest zone of inhibition (8mm) at the concentration of the extract test (1g/3m...

ANTIMICROBIAL AND PHYTOCHEMICAL ACTIVITIES OF Datura stramonium (GEGEMU LEAVES)

1.0 INTRODUCTION  Daturastramoniumis an annual herb, with stem erect and spreading branches above. It is common in the waste land, fields and gardens in Baghdad district. Leaves, seeds and roots contain the alkaloid daturine (a mixture of the two alkaloids hyoscyamine and atropine) and also contain scopolamine alkaloid (Hyosine) acids, tannin and fatty oil. Plants are rich source of secondary metabolites with interesting biological activities (Palombo and Semple, 2001; Koduruet al., 2006). S...

Yeast Mutagenesis

Mutagenesis Lab Procedure   1. Clean your hands and work area. • Clean your hands with hand sanitizer • Put all the food away 2. Acquire a Petri dish from your instructor and label it using a waterproof marker. • Write your name in small letters around the outside edge of the bottom of the dish. • Draw lines on the bottom of the dish to divide it into 3 parts. • Label one area “control”.  What is a control and why do you need i...

CONCEPT OF ENERGY GAP IN SUPERCONDUCTORS

ABSTRACT The concept of Superconductors in relation to energy gap was considered in this study. The occurrence of the Meissner effect indicates that superconductivity cannot be understood simply as the idealization of perfect conductivity in classical physics. The major aim of this project is to study the concept of energy gap in super conductors other objectives of this study are to appraise the rate of superconductivity for energy gaps and to appraise the effectiveness of energy ga...

Investigation on plastic degrading bacteria

                         Abstract This review lays emphasis on the research works carried out across the globe on plastic degrading bacteria. The field of Microbiology is proving to have immense importance in eradicating pollutants from the environment in the long run. One of the most worked on research is on bacterial species that can degrade biodegradable plastic. Biodegradable plastics are made of monomers which bond via ester or ether bonds. Plastics are considered to be one ...

THE USE OF MICROBES AS BIOFERTILIZERS

ABSTRACT   With the ongoing adverse effects of using Chemical fertilizers to both the plants, human and animal life, it has become imperative to seek an alternative to this menace. A biofertilizer is a substance which contains living microorganisms which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Some common agents in biofe...

DESIGN AND IMPLEMENTATION STUDENT BIOMETRIC ATTENDANCE SYSTEM.

ABSTRACTWiththis manual system, there are cases that some student and staffs cheat byasking their friends to tick or sign for them. This occurs because the studentsjust want to fulfill the 80% of the attendance so that they can seat for thefinal examination at the end of the semester. Lecturerand administration fine it difficult to take record of a populated class andstaffs it is difficult for lecturer to record the attendance of studentsaccurately and efficiently. Lecturers are responsible t...
