Aspergillosis

SECTION 1 1.0       Introduction Aspergillus species are ubiquitous opportunistic moulds that cause both allergic and invasive syndromes. The genus comprises approximately 180 species, of which 33 have been associated with human disease. Most infections are caused by Aspergillus fumigatus, Aspergillus flavus, Aspergillus terreus, and Aspergillus niger (Lee J.Y., et al. 2001). Less commonly, Aspergillus nidulans can be implicated as the causative pathogen, especially in the setti...

SURVEY OF WIRELESS POWER TRANSFER TECHNIQUES IN CHARGING MOBILE DEVICES

ABSTRACT Wireless power transmission is the transmission of electrical energy from one point to another without using any conductor or wire through vacuum or atmosphere. It is useful to transfer electrical energy to those places where it is hard to transmit energy using conventional wires. The advent of various wireless technologies have revolutionized the communication infrastructure and consequently changed the entire world into a global village. Use of wireless technology has also been mad...

Design and implementation of a point of sales system

ABSTRACT The global community especially the technologically advanced world is striving to attain what has been the global information age. It is an age that is envisaged to go beyond the use of computers as a mere tool for fast information processing, rather they will also become medium for processing and transferring such information from one location to another at equal fast rate. As a result, its appalling that sales in developing country like Nigeria have not been able to benefit much fr...

Computer and its Architecture

Computer Architecture Computer technology has made incredible progress in the throughly 60 years since the first general-purpose electronic computer was created. Today, less than $500 will purchase a personal computer that has more performance, more main memory, and more disk storage than a computer bought in 1985 for 1 million dollars. This rapid improvement has come both from advances in the technology used to build computers and from innovation in computer design. Although technological i...

Data Recovery

ABSTRACT The aim of this seminar paper is to examine data recovery and its security measures in computer systems. It is aimed at threating recovery data loss in hand device, hard drive failure, data corruption or accidental deleting of files. Unfortunately, despite of constantly growing reliability of storage devices, loss of digital information remains a common phenomenon. General causes of data loss include hardware or software failures, power cuts, software malfunctions (including computer...

EPIDEMIOLOGY OF VIBRO CHOLERAE 0139 INFECTION

INTRODUCTION Cholera is an acute bacterial infection of the intestine caused by ingestion of food or water containing Vibrio cholerae, serogroups  O139, it  is a disease characterized by profuse diarrhea accompanied with a severe dehydration and loss of electrolyte (Colwell and Huq, 1994), caused by toxigenic Vibrio cholerae, a serologically diverse, environmental, and gram-negative rod bacterium (Li et al.,2002). In the absence of appropriate treatment, there is a high mortality rate. Cho...

BACTERIOCIN IN FOOD PRESERVATION

INTRODUCTION In the production of food, it is crucial to take proper measures to ensure its safety and stability during the shelf-life. At present, many food industries are faced with different microbiological problems such as emergence of new pathogens and pathogens not previously associated withfood consumption, as well as the ability of microorganism to adapt and its resultant mutation that has given rise to altered food safety (Galvez et al., 2007). The empirical use of microorganism...

DRUGS DISCOVER FROM SOIL MICROORGANISMS

1.0 INTRODUCTION Back in 1928, Alexander Fleming began the microbial drug era when he discovered in a Petri dish seeded with Staphylococcus aureus that a compound produced by a mold killed the bacteria. The mold, identified as Penicillium notatum, produced an active agent that was named penicillin. Later, penicillin was isolated as a yellow powder and used as a potent antibacterial compound during World War II. By using Fleming’s method, other naturally occurring substances, such as chl...

Water and Sanitation Target (MDGs)

INTRODUCTION The Millennium Summit in September 2000 and held in New York City was described as the largest gathering of global leaders in history. The three-day summit was one where 149 global leaders gathered on the table of brotherhood. Three days after, the leaders arrived at the Millennium Declaration which automatically became known as the Millennium Development Goals (MDGs). The millennium development goals (MDGs) is a set of eight point agenda adopted by all member states includ...

AQUATIC INSECTS AND THEIR ECOLOGICAL BENEFITS

ABSTRACT This seminar work on the ecological benefits of aquatic insects was done taking into consideration basic questions and concepts that can be derived from the given topic of study.Some of these questions included -What is an insect?-What is an aquatic insect?-Types of aquatic insects-What is ecology?-Types of ecology-Aquatic ecology-Aquatic insects and their ecological benefits, were used to indicated the depth this work is going to cover.  Information on the aquatic insects and thei...

POST MILLING EFFECT OF STORAGE ,TEMPERATURE ON BREAD BAKING QUALITY OF REFINED WHITE FLOUR,WHEAT BREAD AND THE ROLE OF FLOUR LIPIDS

1.1INTRODUCTION  The USDA issued a Dietary Guidelines recommendation on June 12th, 2005 for consumers to increase whole grain consumption. However, it is generally recognized that wheat flours containing the germ can develop problems due to lipid changes. White flour, especially soft wheat flour destined for use in cakes, increases in quality with time after harvest and milling, as indicated by a desirable drop in batter specific gravity and increase in batter viscosity, distilled water bind...

Influence of genetics and environment on grain quality.

AbstractWheat grain quality are strongly influenced by the effects of environment during grain fill. Environmental variables such as temperature, water and fertilizer influence the rate and duration of wheat grain development, protein accumulation and starch deposition in unique ways, and by different mechanisms. The effects of environment are superimposed on the intrinsic temporal patterns of gene expression during grain development. Integration of genomic and proteomic studies with developm...

ENVIRONMENTAL DEGRADATION, CLIMATE CHANGE, MIGRATION AND YOUTH

ENVIRONMENTAL DEGRADATION, CLIMATE CHANGE, MIGRATION AND YOUTH   Within the debates on the consequences of climatic and ecological change, international attention has become increasingly focussed on the links between environmental change and human migration. Several international organisations such as UNHCR, UNFCCC, IOM and UNICEF are addressing this issue. Furthermore, a series of research initiatives focusing on the link between environmental change and migratio...
