Mortality Rate of Houseflies Exposed to Some Selected Insecticide to Some

Abstract Houseflies are pest in homes, dairies, barns, poultry houses, recreation areas and food processing sites. The study is to evaluate the susceptibility of Musca domestica to deltamethrin, cypermethrin and DDVP insecticides. Topical bioassay was used to perform adulticidal test, while dipping method was used for larva and pupa, different concentrations were used which ranges from 0.5ml/L-10.0 ml/L for larvae and pupae while 5.0 µL/fly-50.0 µL/fly was used for adult Musca domestica. Th...

Optimization and Screening of Extracellular Enzymes produced by Pseudomonas Aeruginosa during LDPE degradation

ABSTRACT Plastics are synthetic polymers made by chains of carbon atoms with hydrogen, oxygen, nitrogen, Sulphur built around the carbon chains (Shah et al., 2008). These polymers are involved in every domain of our lives ever since its production began from the year 1950’s, plastics have been produced at an augmented rate to meet day to day demands of the entire world. Accumulation of plastic waste in the environment causes chemical pollution when methods like incineration are used to get ...

The Impact of Climate Change on African Commodity Trade

Africa is the world's second-largest continent, covering an area of approximately 30.2 million square kilometers. It is home to 54 countries, each with its unique culture, history, and natural resources. The continent is rich in natural resources, including oil, gas, minerals, and agricultural commodities, which are in high demand globally. The African continent plays a significant role in the global commodity trade, providing the world with critical raw materials. Africa is a leading produce...

Phytochemical Analysis and Effect of Sodom Apple (Calotropis procera (Aiton)) on Maize Weevil (Sitophilus zeamais(Motsch.) in Storage in Bauchi

ABSTRACT Laboratory experiment was conducted to determine the insecticidal activity of leaves and stem bark powder of Sodom apple (Calotropis procera) and optimum concentration for the management of maize weevil (Sitophilus zeamais). Actellic dust 50g was used as positive control and untreated Maize seeds serving as negative control. The experiment was laid in Completely Randomized Design (CRD) comprising of Leaf powder (1, 3 and 5 g), stem bark powder (1, 3 and 5 g), Actellic dust and contro...

Water Purification Characteristics of Chitosan

ABSTRACT Alum (potassium aluminum sulfate-K+Al3+ (SO42-) 2), ferrous sulfate (Fe2+ SO42-), ferric chloride (Fe2+2Cl-) and ferric chloro-sulfate (Fe2+Cl-SO42-) were commonly used as coagulants. However, a possible link of Alzheimer’s disease with conventional aluminum based coagulants and other adverse bioaccumulation cases associated with heavy metal have become an issue in wastewater treatment. Hence, special attention has shift towards using biodegradable polymer like chitosan in treatmen...

Electrochemical Study of Conducting Polymer/Lignin Composites

Electropolymerization and redox behavior of lignin composites were characterized by cyclic  voltammetry (CV), electrochemical quartz crystal microbalance (EQCM), and Fourier transform  infrared spectroscopy (FTIR). Oxidation of lignin (LG) composites mixed with different polymers such  as; Poly (o-phenylenediamine) (POPDA), Pyrrole (Py), 4-amino-3-hydroxynaphthalene-sulfonic acid  (AHNSA) on working glassy carbon electrode (GCE) were performed by cyclic voltammetry in a  three-electrode ...

BIOACCUMULATION OF PERSISTENT POLLUTANTS IN AFRICAN CATFISH

This project titled Bioaccumulation of persistent pollutants in Clarias gariepinus gotten from Ogu Creek is based on ecotoxicology and utilized African catfish (Clarias gariepinus) as a model in estimating the bioaccumulation of pollutants in living tissues of organisms in Ogu creek which is a point of poorly treated effluent discharge. The persistent pollutants include Zn, Cr, Cd, Pb, Mn, and Total Petroleum Hydrocarbon (TPH). The concentrations of the heavy metals were determined with Atomi...

Green Mediated Ferrofluid as a Probable biofuel for Sustainable Aviation Fuel : Review, Practical Evaluation and Prospective Applications

The agenda of the United Nations Sustainable Development Goal and the international Energy Agency tailored towards addressing the global crisis  of climate change mitigation (depletion of the Ozone layer is of great concern due to the adverse effect of carbon emission activities which has proven to be pungent, lethal, non-degradable with zero socio-economic relevance). Hence,  this research study under a feasibility check investigated the possibility of synthesizing green ferrofluid from pl...

Geology And Occurrence of Groundwater In Ishieke Area, Southeastern Nigeria

ABSTRACT  The study area is located in the Abakaliki formation of Asu-River group Lower Benue Trough. The area lies between latitude N060221 011to N060 281 011of the equator and longitude E0080 001 011 to E 0080 061 011of the Greenwich meridian. The study was carried out to ascertain the geology and the occurrence of groundwater in the area through detail geological field mappings geophysical investigation and pumping test. Field observations shows that the area is made up of two lithologic...

Uncovering the Hydro‑meteorological Drivers Responsible for Forest Fires Utilizing Geospatial Techniques

Abstract Forest fires have become a growing concern worldwide, with climate change exacerbating their frequency and intensity. In the Simlipal region of India, forest fires are relatively rare; however, in 2021, significant damage occurred in the buffer area’s forests. Understanding the driving factors behind these events is essential for developing effective management strategies. This study investigates the impact of hydro-meteorological conditions on forest fire causes in the Simli...

Design and Construction of Paint Factory in Makurdi

CHAPTER ONE INTRODUCTION 1.1  BACKGROUND TO THE STUDY Paint Factory or plant is an industrial site, usually consisting of buildings and machinery, or more commonly a complex having several buildings, where workers process raw materials into paint. Factories arose with the introduction of machinery during the industrial revolution when the capital and space requirements became too great for cottage industry and workshops. Paint is a subdivision of surface coating. It is a relatively opaq...

The Design of a Disaster Management Centre, Port-Harcourt

INTRODUCTION  "Disaster management" can be defined as the range of activities designed to maintain control over disaster and emergency situations and to provide a framework for helping at-risk persons to avoid or recover from the impact of the disaster. Disaster management deals with situations that occur prior to, during, and after the disaster. Globally, there has been lots of disaster on land, air and sea, though these disasters may be natural or man-made, it has however led to the destru...
