This study was used to assess public opinion of the economic and ecological importance of various tree species in Kaduna Metropolis, Kaduna state. A total of one hundred (100) questionnaires were randomly administered among four purposively selected towns (Angwa-Rimi and Kawo new extension in Kaduna North and Bar’nawa and Sabo in Kaduna South) within the two major local governments in the study area...
The pollution of surface water and sediments by heavy metals has become a difficult thing to deal with due to their toxicity and accumulative behavior. The present study was undertaken to provide information on the concentrations and distribution of selected heavy metals in surface water and sediments from Warri River, and to compute a contamination/pollution index of heavy metals. Surface water and...
In this work, the potentials of adhesives production from cassava starch were investigated. An adhesive product produced from Manihot utilissima was compared with a commercially available adhesive. Improvements in the properties of the cassava-based adhesive were achieved by investigating the effects of temperature and the addition of a viscosity enhancer/stabilizer (borax) on the density of the produced...
The aim of the study was to isolate and identify the extent of Salmonella and Shigella induced diarrhoea in children under five and to determine their antibacterial susceptibility patterns. The method of investigation was a cross-sectional study. Samples were collected from children less than five years old afflicted with diarrhoea coming for treatment at Thika Level Five Hospital, Kiambu County....
In the current research, we surveyed the effective factors of accidents that had occurred on the road from Hamadan to Sanandaj. Road transportation is an inseparable part and the backbone of all transportation networks of most countries. Driving accidents are considered the major problem of road transportation and the increment process of accidents is so that it has reached crisis proportions. Basically,...
The main objective of this research is to determine the content of metals (Ca, Cu, Fe, Mg and Zn) and total phenols in different plant extracts of Moringa oleifera, Cassia tora, Ocimum gratissimum, Vernonia baldwinii and Telfairia occidentalis. Content were determined using Atomic Absorption Spectroscopy. The result indicate that Moringa oleifera plant extracts range from 0.25 ±0.00 to 6.13 ±0.30...
The purpose of the research work was to examine the antifungal properties of cumin, rosemary and fennel essential oils. The goal of the study was also to determine antifungal activity of coatings containing the essential oils. The results of the study demonstrated that cumin, rosemary and fennel essential oils exhibited antifungal properties. The most sensitive strains were Botrytis cinerea and Mucor...
Conserving biodiversity is a major necessity, as human interference causes loss of this. Tourism is not exempt from this. Still, ecotourism, a sub-component of the field of sustainable tourism, has more positive effects. The primary objective of this work is to ascertain the condition of ecotourism in the study area. The secondary objectives are to identify the challenges and progress of biodiversity...
A study was conducted to investigate the effect of growing location in the physico-chemical properties of gum arabic obtained from Acacia senegal. Authentic representative gum exudates samples were collected from Abederafi, Yabello, Awash and Filtu areas of Ethiopia. The experiment was conducted to determine Moisture content (MC), Ash content (Ash), pH, Relative Viscosity (RV), Nitrogen (N), Crude...
The microorganism associated with cassava fermentation for producing Abacha was investigated using four different Farms in Owerri (Obinze, Umugwuma, Urata and Orji) as sample collection areas. Four of the cassava tubers that harvested, were washed, cooked and soaked with water after cutting to produce Abacha, which was then fermented using standard microbiological methods. The wastewater was subsequently...
The current study was aimed to find out the heavy metal concentration of groundwater in the Veppanthattai block. Here, 45 water samples from different sites were collected during the year 2015 at post monsoon, and Cd, Cr, Cu, Fe, Ni, Pb and Zn heavy metal content was analyzed using an atomic absorption spectrophotometer (AAS), The obtained results were then compared with the WHO standard for the specific...
This paper is a study of G6PD activity in malaria-infected children in Owerri. Blood samples were collected from fifty-one (51) children hospitalized in the Federal Medical Center (FMC) and analyzed using standard Medical Laboratory methods. Results revealed that out of the 51 children examined (26 males and 25 females), 39, representing 76.47% of the total malaria infected children numbers, were...
Flood events often have severe socio-economic impacts, such as loss of lives and livelihoods, food, water and energy scarcity, and adverse impacts on human health and the environment. As far as feasible, human interference into the processes of nature should be reversed, compensated and, in the future, prevented. This study explores the possible solutions for the drainage system to ensure peak performance...
We investigated the efficiency of maize biomass parts - seed chaff, stalk, cob and husk, in the remediation of Cu2+ ion polluted water in modeled solutions. The adsorption capacity of these parts followed the order of husk > stalk > cob > seed chaff, with values of 9.65 mg/g, 4.83 mg/g, 3.70 mg/g and 2.48 mg/g, respectively. Maximum adsorption capacity of each part was reached in 45 min....
Environmental pollution has resulted in several health and physiological problems in both plants and animals. This has witnessed growing number of models for assessment purposes. Some of these provide useful information, and reduce large data for easier understanding by policy-makers. In the current study of pollution, we used data from four locations: Oil Market, Trans Amadi, Borrokiri and GRA in...
This study investigated the effect of storage on certain sachet water quality indicators over a twelve-week period. Three brands of sachet water were collected within 24 h of production and analyzed for pH, nitrate, phosphate and dissolved oxygen. These were then placed in normal storage. According to out results, pH values increased significantly in all brands after week 8. Moreover, nitrate and...
During steady-state operation, hot-coiled filaments in incandescent lamps provide luminous flux for illumination, but when switched off, the temperature, as well as the light output drops quite fast. The cooling-time of a lamp is the time required for the hot filament to cool down to ten per cent light output after the circuit is opened. In this paper, the exercise of estimating luminous flux and...
Constituents of the ethanol extract of Sida acuta (SA) leaves were investigated by phytochemical, GC-MS and FTIR studies and its corrosion inhibition effects on mild steel was studied in 1 M HCl and 0.5 M H2SO4 solutions, using gravimetric and electrochemical methods of corrosion monitoring. The surface morphology of the mild steel surface before and after corrosion was also assessed using SEM imaging...
Individual tree growth models are important decision-making tools in forestry. This study evaluated the predictive ability for basal area, of a Java program derived from the algorithm of gamma distribution function. The input value was diameter at breast height. In generating and testing the program, a stratified random sampling technique was used to select four different age classes of teak plantation,...
Flooding is a natural event that replenishes the groundwater and revitalizes the soil through the deposit of sediments. However, when communities settle within floodplains, flooding can cause adverse social, economic and environmental impacts. Flood protection works, such as dikes, can further reduce flood risk. These structures particularly relevant in protecting historic communities that were settled...
