ABSTRACT Anopheles gambiae, the major Afro-tropical malaria vector is resistant to pyrethroid insecticide and this is threatening the impact of malaria control efforts using insecticides. In this study, the major malaria vector species from stagnant water bodies and their susceptibility status to pyrethroid insecticide was determined in some areas of Lagos state, Nigeria. Anopheles larvae were sampled from three areas of Lagos, namely Akoka, Idiaraba and Okobaba and raised to adulthood in the...
ABSTRACT Oil spills have become a major environmental hazard constituting serious social problems in Nigeria, especially in the oil producing communities. The geoelectric technique of geophysical investigation has been used to evaluate possible pollution of the groundwater by hydrocarbon as a result of oil spills in six oil producing communities comprising of Olch, Olomoro, Uzere, Aficsere, Ekakpamre and Uvwiamuge within the western Niger Delta. A total of one hundred and thirty nine vertical...
ABSTRACT Vernonia Schreb. is a genus in the family Asteraceae. It has over 1000 species which may be trees, shrubs, woody climbers or herbs. Some of the species are economically important as sources of food and herbal medicine as well as for industrial purposes. Despite the economic importance of the species, the existing taxonomic and phylogenetic relationships among the taxa are not totally resolved. The objective of this study was to assess the genetic diversity of Vernonia species in Nig...
ABSTRACT. The study revealed that there was a quantitative recruitment in colonies of Amiternes evuncifer, whenever food was discovered by the scouting foragers. Discovered food stimulated the termites to accelerate their running speed, to and from the food source. Increased trail-laying activity, accelerated movement and carrying of food by the returning workers facilitated recruitment of other confederates from their nest. These activities equally directed the recruited termites to the food...
ABSTRACT Aloe vera gel (AVG) extract is commonly used as a home remedy for some diseases, including diabetes mellitus. This study investigates the effects of pure Aloe vera (Aloe babardensis) gel on some biochemical, haematological and histological parameters in diabetic rats. The animals were divided into six groups of six rats each (n=6). Diabetes mellitus was experimentally induced in rats by intraperitoneal administration of a single dose of alloxan monohydrate (170 mg/kg BW.) following ...
ABSTRACT The absence of regulatory control of HIV test kits in use, non-availability of HIV testing algorithm and absence of regular and constant evaluation programme for HIV testing kits stimulated the authors' curiosity to carry out both operational and experimental studies on the commercially available HIV test devices circulating in the Nigerian market. A scientific approach to address the setbacks in HIV testing methods contending with HIV serodiagnosis and surveillance, as well as deter...
ABSTRACT The classication of Smooth Geometric Manifolds still remains an open problem. The concept of almost contact Riemannian manifolds provides neat descriptions and distinctions between classes of odd and even dimensional manifolds and their geometries. Among the classes that have been extensively studied in the past are the Hermitian, Symplectic, Khalerian, Complex, Contact and Almost Contact manifolds which have applications in M-Theory and supergravity among other areas. The dierential...
ABSTRACT Microbes capable of degrading atrazine were isolated by traditional enrichment technique from composite soil samples collected from four agricultural farmlands with long history of atrazine use in Nigeria. The estimated atrazine degrading populations from Obasanjo, Ladipo Daniel, Agbowa - Ikosi and Itokin farms were 1.6 x 10* cfu/mg, 8.0 x 10^cfu/mg, 5.0 x 10* cfw/mg and 1.2 x 10 cfu/mg of the soil samples respectively. The soil sample from Obasanjo farm was selected for further stud...
bstract The recovery towards a natural state of a restored Rhizophora mucronata mangrove ecosystem was investigated by assessing the sediment physical characteristics, densities, community composition and diversity of benthic macro-endofauna and meio-endofauna from a natural, a 10 years reforested, a 5 years reforested and a degraded (clear felled) mangrove ecosystem. The natural forest was used as a reference (baseline state) while the degraded site was to provide information on the effects ...
ABSRACT Primarily, the project has focused on finding out the Online Buying trends and behavior of Maasai Mara university consumers with an age range of 18- 25 years. The proposed primary objective of the study was further divided into secondary objectives with an aiming of finding detailed information on the research topic. Precisely, information regarding buyer’s buying frequency, average spending, and famous product purchase was gathered. Since the objectives were quantifiable, a quantit...
ABSTRACT The oldest system of tanning relies on the chemical action of vegetable materials containing tannin and tannic acid on the protein constituents of skin or hides.
Abstract Plant-based repellents have been used for generations in traditional practices as a personal protection measures against host seeking insects like mosquitoes. Knowledge on traditional repellent plants obtained through ethnobotanical studies, is a valuable resource for the development of natural and environmental safe products. Recently, commercial repellents containing plant based ingredients have gained increasing popularity among customers. These are commonly perceived as ‘safe�...
ABSTRACT The project presented here gives a user an online easy use and access to a Kamusi which is for convenience and technologically oriented type of study and research. This project aims at making Swahili language available for use to the entire world and for the perfection of the language and its masterly. The online Survey conducted shows that there is need for a better Kamusi. Available ones do not have pictorial representations and therefore on launching; this will be one of...
ABSTRACT This project work presents the design of an automated room temperature controller system. This system allows the user to set a desired temperature which is then compared to the room temperature measured by DHT11 temperature sensor. With the help of Atmega 328 based on Arduino microcontroller, the system responds by turning ON and OFF the two (2) loads (fan or a heater) automatically depending on the temperature difference in the room. The fan is triggered ON when the room temperature...
ABSTRACT The local bean varieties most common among farmers of Narok south is depended upon by other residents of Narok county and other regions within the country as their main source of food which has got high protein content and as well as source of income .This research was mainly aimed at determining the best performing local bean varieties in lowland areas of Narok south. It also aimed at determining if there exists a significant difference between blocks which are the yearly mean yield...
