Fungal Culture From Yam Rot Using Different Dextrose Agars

ABSTRACT The effectiveness of cotton seed dextrose agar, groundnut seed dextrose agar and kernel dextrose agar in culturing fungi was studied by culturing fungi from yam rot (Dioscorea rotundata). The research demonstrated the choice of the isolated fungi to various media, and revealed that some of the isolated fungi showed the same occurrence in different media. Aspergillus flavus showed preference for kernel dextrose and groundnut seed dextrose agar than Sabouraud dextrose agar and cotton s...

Comparative Assessment of Growth Potential of Low-cost Formulated Diet for Catfish (Clarias gariepinus) Production

A comparative assessment of growth potential of low-cost formulated diet for catfish (Clarias gariepinus) production was conducted using a low-cost formulated diet and commercial fish feed (Multifeed). An experiment was carried out to determine the effect of the locally-formulated feed and the commercial feed on the weight and length of catfish samples at 3% body weight (b.w) and 5% body weight (b.w) respectively. Forty (40) juvenile catfish samples, with average weight of 8.07g and average l...

Studies on Incidence and Effects of Temperature and Relative humidity on Post harvest rot of Cocoyam (Colocasia esculenta) in Gombe community, Gombe State, Nigeria

Studies on incidence and effect of temperature and relative humidity on post-harvest rot of cocoyam (Colocasia esculenta) were conducted in Bolari, Pantami and Tudun Wada district headquarters in Gombe LGA of Gombe state, Nigeria. The aim was to determine the incidence and severity of post-harvest rot of cocoyam (Colocasia esculenta), to isolate and identify the fungi responsible for the rot, to determine the virulence of the pathogen and the effect of temperature and relative humidity on...

Effect of Variations in Meteorological Parameters on the Tropospheric Radio Refractivity Over Lapai, Niger State, Nigeria

ABSTRACT The aim of this work is to examine the variations in meteorological parameters (Temperature, Atmospheric pressure, and Relative humidity)on the surface radio refractivity, N, in Lapai town, Niger state of Nigeria, with focus on the wet and dry seasons. Lapai town, being the study area, is located within latitude 9º 02ʺ N and longitude 6º 34ʺ E along Suleja road, about 56 km east of Minna, Niger state capital. Meteorological data obtained from the Nigerian Meteorological Agency (N...

PALEO-ENVIROMENTAL ANALYSIS OF ANAMBRA BASIN SEDIMENTS. A CASE OF ACHARA-UGWUEME AND ENVIRONS, SOUTH EASTERN, NIGERIA.

Abstract:  Paleo-environmental study of Achara-Ugwueme in Anambra Basin was studied using Textural analysis parameters, which includes paleocurrent analysis, sieve analysis and pebble morphological methods. The paleocurrent result shows that the variance value is 1701 which indicates that the units were deposited in fluvial environment. The azimuth with rose diagram suggested southwesterly direction of paleocurrent during the time of deposition, thus pacing the provenance at northeast, p...

ENHANCEMENT OF METHANE PRODUCTION BY CODIGESTION OF KERATIN AND CELLULOSIC FEEDSTOCKS AT MESOPHILIC AND THERMOPHILIC CONDITIONS USING MICROBIAL CONSORTIA

ABSTRACTNigeria has energy crisis, hence, there is urgent need to diversify the country’s energy resources towards renewable alternatives for economic and social transformation. Biogas generated from the anaerobic digestion of local biomass resources, will increase national energy security as well as reduce dependence on fossil fuels. Optimization of methane production by codigestion of poultry feather and sawdust using microbial consortia were investigated. The results of the molecular ide...

ISOLATION AND CHARACTERIZATION OF MICROORGANISMS ASSOCIATED WITH BIOREMEDIATION OF HYDOCARBON POLLUTED SITES

Abstract:  The negative impacts of hydrocarbon pollutants on our environments and economic resources cannot be overemphasized. The need to harness the bioremediation potentials of microorganisms associated with hydrocarbon pollution becomes very imperative in order to mitigate the environmental impacts of petroleum hydrocarbons in our environments. The molecular identification of the microorganisms isolated from four automobile workshops at Ugbene 2 Abakpa Nike, Enugu, Nigeria based on 1...

PRODUCTION OF COMPOSITE YOGHURT FROM BLEND OF SOY MILK AND COW MILK USING MIXED LACTIC STARTER CULTURES ISOLATED FROM AQUARAPHA YOGHURT

ABSTRACTThe need to improve our vegetable protein consumption in order to reduce the incidence of protein deficiency diseases cannot be over-emphasized. This research was premised on evaluating the appropriate levels of substitution of cow milk with soya milk to produce composite yoghurt. Eight hundred (800) grams of soya bean seeds after sorting out foreign materials and washing were usedto produce 4.0 liters of soya milk (20% total solids). Cow milk (20% TS) was blended with soya milk in th...

Are The Crypto Wars Over? Encryption, Internet Governance, And The Internet Society Action Plan 2021

In the 21st Century, security and privacy threats extend the physical into the Internet, and as a result, create the need for Internet security and /privacy. One of the ways Internet security and privacy can be achieved is through a cryptographic methodknownas Encryption - commonlyusedbypersons and governments to secure data on Internet - accessible systems against unauthorised access. Yet, Encryption technologies face certain threats and challenges. Private firms and go...

PALEONTOLOGICAL EVALUATION OF IMO SHALE AT UMUNAUMUAWO, EZEAGU, ANAMBRA BASIN, NIGERIA: AGE AND PALEOENVIRONMENTAL SIGNIFICANCE

Abstract The lithofacies and foraminiferal assemblages of the Imo Formation exposed at Umuna-Umuawo, Ezeagu, Anambra Basin were evaluated for the purpose of environmental interpretation and age dating. Lithofacies were described based on lithology. The lithologic units of the succession are basically dark-grey to bluish-grey shales with presence of gastropod mineralized shells depicting a marine depositional environment. The shale is interbedded with patches of siltstone and clay beds. The me...

DESIGN AND INSTALLATION OF AN AUTO-SOLAR POWERED SYSTEM

ABSTRACT Researchers suggest that the amount of sunlight that strikes the Earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a full year. Solar power system is one of the best renewable energy technologies which is not only cost effective but environment friendly as well.This study aimed at designing and installing a quite low-cost inverter of 3.5KVA with high efficiency and quality output capabilities to power some appliances of a total load...

Internet of Things

                                                                    ABSTRACT The internet of things which is the current wave in the development of the internet has been around for some time. It is specifically about connecting objects (things) that would not ordinarily be considered worthy for internet connectivity.
