ABSTRACT In order to search for alternative control methods to synthetic pesticides, the potential of essential oils 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 pairs of newly emerged weevils and, fumigated with 0, 1, 2, 3, or 4μl of essential oils of garlic/l of air. The essential oils of garlic were analyzed by GC-MS. The majo...
ABSTRACT Understanding the spatial variation of urban heat Islands (UHI), will be helpful in urban micro climate studies. This study the urban heat islands of Kaduna metropolis, Nigeria. For the present study Landsat ETM+ images of 2001, 2006, 2009 and OLI 2015 was obtained from USGS of the study area. Normalized Difference Vegetation Index (NDVI) image was developed. The digital number of thermal infrared band is converted in to spectral radiance using the equation supplied by the Landsa...
INTRODUCTION This is the good Bio-Technology project on "development of biochemistry liquid stable reagents used for the estimation of Sodium and Potassium electrolytes in blood serum", which covers study based on Sodium and Potassium reagents. Chemical pathology (more commonly known as clinical biochemistry or clinical chemistry) is the area of pathology that is generally concerned with analysis of body fluids and extracts and will be used in this report This research study is based on S...
Abstract A Java Ring is a finger ring that contains a small microprocessor with built-in capabilities for the user, a sort of smart card that is wearable on a finger. Sun Microsystem´s Java Ring was introduced at their Java One Conference in 1998 and, instead of a gemstone, contained an inexpensive microprocessor in a stainless-steel iButton running a Java virtual machine and preloaded with applets (little application programs). The rings were built by Dallas Semiconductor. Workstations at t...
ABSTRACT Street food vending has become an important public health issue and a great concern to everybody. This is due to widespread of food borne diseases, due to the mushrooming of wayside food vendors who lack an adequate understanding of the basic food safety issues. Major source contributing to microbial contamination are the place of preparation, utensils for cooking and serving, raw materials, time and temperature abuse of cooked foods and the personal hygiene of vendors. Various stu...
Planet earth is being endangered by anthropogenic activities ranging from industrial activities to seemingly innocous activities such as use of herbicides on farms.There are possibilities that the resources of the earth may not be sufficient to sustain the needs of future generations.There are also possibilities that the earth may become in conducive for human habitation due to emission of dangerous gases and...
ABSTRACT Climate change has been identified as one of the greatest challenge by all the nations, government, business and citizens of the globe. The threats of climate change on our green planet ‘Earth’ demands that renewable energy share in the total energy generation and consumption should be substantially increased as a matter of urgency. Nigeria’s energy development programme has been put under severe pressure with the ever-increasing demand supply gap. Due to predominance of fossil...
Time lapse seismic which geophysicists often abbreviate to four dimensional (4-D) seismic is a geophysical technique which involves simply repeating a series of 3-D seismic survey over time such that the fourth dimension is in “Calendar Time”. This gives it the ability to image fluid flow in a well volume.
Fibre optic technologies came out of military and space research and development programme. Until recently, glass chemistry and laser interrogation hardware have not been at a level of robust where systems could survive in down-hole environments for long periods. Because of the physical properties, glass can thrive as a sensor at extremely high temperatures and efficiently high temperatures and efficiently transmit large quantities of data where as in the past, one may have been limited to a ...
Seismic survey has long become a trusted tool for hydrocarbon exploration. This is because of the outstanding ability of seismic reflections and their over lapping relationships to image deep and shallow subsurface structures and delineate promising structural and stratigraphic traps. These subsurface features become good prospecting targets, maybe because of their depositional history or post depositional events. With this in mind, it is necessary to draw out relationships between deposition...
Forensic geophysics can be seen as that involving the use of geophysical methods in the search, locating and mapping of hidden or buried features underground or underwater. Geophysical methods have the potential to aid the search and recovery of a target because they can nondestructively and rapidly investigate large areas where a suspect, illegal burial or, in general, a forensic target or object is hidden in the subsurface.
Geophysical field school is an annual academic camping exercise that is aimed at exposing students to the practical aspects of geophysics. It is a three (3) credit hour course for third year students of applied geophysics aimed at educating students on the handling of geophysical equipment and the rudiments of data acquisition, processing and interpretation. This year’s field school was held at Ikot Nakanda and its environs, in Akpabuyo locall government area of Cross River State. It w...
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...
INTRODUCTION Information is not only the basic of human existence. It is also the life wire for running of any organization. This is consequent upon the fact that decisions are based on information for effective decision-making and effective execution of those decisions, there must be constant information flow. Data gathered must be transmitted to the end –users after it had been processed. Information receipt processing, storage, dissemination, etc. may be instant; otherwise valuable bus...
PREFACE Food poisoning might be described as a food borne diseases or food borne illness. Food that contains a toxin, chemical or infectious agent (like a bacterium, virus, parasite or prion) and causes symptoms in the body are considered types of food poisoning by most investigators. Those symptoms may be related only to the gastrointestinal tract causing vomiting or diarrhea or may involve other organs such as the kidney, brain or muscle. This term paper considered that, it can be treated...
