Effect of Different Organic and Inorganic Nitrogen Sources on the Kinetics of the Breakdown of Crude Oil Using Pseudomonas

ABSTRACTThe option of using microbes in the remediation of polluted sited have received wide acceptance due to its sustainability and environmental friendliness. This study is aimed at using the kinetic parameters (Vmax and Km) to assess the effect of organic and inorganic nitrogen sources on the performance of Pseudomonas sp., during the remediation of crude oil polluted sites. The rate of crude oil breakdown was assessed by determining the total petroleum hydrocarbon in the soil (after cont...

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

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...

Isolation and characterization of lactic acid bacteria from locally fermented milk

ABSTRACT Nunu is a spontaneously fermented yoghurt-like milk product consumed as a staple food commodity invirtually all parts of the Country. Its production and consumption gives way to much food security and economic benefits to the rural people. However, the process characteristics result in products which are not appealing to many people, have very short shelf-life and could have food safety concerns. In a framework of research to improve the product quality and increase consumption, a st...

An Integrated approach to mapping theconcentration and pathway of leachate plumesbeneath a dump site in South-western Nigeria

Abstract—An integrated approach involving Electrical Resistivity Tomography (ERT), Vertical Electrical Sounding (VES), and Very Low FrequencyElectromagnetic (VLF-EM) methods has been used to map the concentration and pathway of leachates plumes beneath Laka dump site in OgbomosoSouthwestern Nigeria. In-situ analysis, specifically, Electrical Conductivity (EC) and Total Dissolved Solids (TDS) were also carried out on water samplescollected from hand dug wells, bore holes and stream around th...

ACID RAIN-THE MAJOR CAUSE OF POLLUTION, ITS CAUSES, EFFECTS AND SOLUTION

                                                                                               Abstract Acid rain, more properly termed acid deposition, is the input of acidifying compounds from the atmosphere to the earth's surface. It is comprised primarily of sulfuric and nitric acids that are formed when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOX) react in the atmosphere with water, oxygen, and other compounds. Chlorine ...

ANALYSIS OF SPATIAL AND TEMPORAL VARIATION OF URBAN HEAT ISLANDS WITHIN KADUNA METROPOLIS

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...

DESIGN AND SIMULATION OF AN ELECTRIC DEVICE WITH AUDIO UNIT.

ABSTRACT This work deals extensively with the design and construction of an electrodice display (EOD) with audio unit. The device displays the value of a ludo dice in numerical form and also produces sound as it displays the number. The device works with principle of chance employed by ludo game players. The output of the display is usually very rapid that the player does not actually see the number when the device is switched ON so that it will purely be a game of chance. When the off key i...
