Abstract: Background: Assessment of groundwater potential zone is extremely important for groundwater management. This study was carried out to characterize the basement rocks and groundwater potentials by delineating the resistivity and overburden thickness of the subsurface lithology of Odeda General Hospital, Southwest, Nigeria.
Materials and Methods An integrated geophysical survey involving the Very Low Frequency Electromagnetic (VLF-EM) and Electrical Resistivity using Schlumberger electrode arrangement were adopted for this study. The VLF-EM data were acquired along five traverses using VLF-EM 34 Meter while ten VES surveys were carried out at areas with anomalous conductivity delineated by the VLF-EM survey using Campus Ohmega resistivity meter. The maximum current electrode spread and potential electrode separation were 200m and 10m respectively.......

Abstract: Background: The study evaluates the persistent organic pollutants and water quality characteristics in the bailed-out waste water from Fish Farm Estate Ikorodu, Lagos. Materials and Methods: The evaluation was carried out for twelve (12) weeks. The study sites were divided into three phases (1, 2 and 3). The water samples were collected from each site into three amber glass bottles for POPs and three plastic bottles for physicochemical parameters respectively for laboratory analyses. Results: The results obtained were subjected to ANOVA. pH, Dissolved Oxygen (DO), Electrical Conductivity (EC), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Dissolved Solids (TDS), Salinity in the bailed-out waste water are statistically significant at (p<0.05). However, Persistent Organic Pollutants (POPs) are not detected in the sampled water......

Abstract: The aim of this study is to assess the ability of Carica papaya leaves to remove heavy metals from contaminated water. Batch experiments models were performed to investigate the optimal parameters such as the time contact, the adsorbent dose, the initial metal concentration. With the variation of concentration, the isotherms and kinetics adsorption were also evaluated. Ten minutes are sufficient to reach the maximum of 84.32% removal of iron from the water. Twenty minutes are necessaire for reaching the maximum removal of nickel (24.01%), of copper (29.77 %), of zinc (16.40 %). A mass of 0.3 g of adsorbent is sufficient to reach the maximum removal of iron from.....

Abstract: Background: Plastics are inexpensive, lightweight, and durable materials, which can be used to develop a variety of products in a wide range of applications. The production of plastic waste has steadily increased over the past 30 years and poses several threats to wildlife and human being. The recycling techniques commonly used for plastic wastes include filling, incineration, chemical or mechanical recycling, and fuel conversion. Circular Economy is an alternative concept for the present linear model of make, use, and dispose of plastics. Recycling aims resource efficiency to extract maximum value by improving waste minimization strategies. In Sri Lanka, the use of plastics has created enormous quantities of waste that causes socio-economic, health, and environmental issues. Currently, circular economy is not effectively practiced in Sri Lanka, since there are no proper circular based structure, plastic recycling, and necessary policies. Therefore, present study reports the amount of plastic waste generated, future trends, gaps in current management strategies, and recycling in order to propose a circular economy-based policy framework to manage plastic waste in Sri Lanka......

Abstract: In production ponds, the performance and yield of catfish (Clariasgariepinus) is determined among other things on the water quality. EM activated for both nutrient EMAS and against pests EM5 were used to treat cat fish concrete ponds at a concentration of 1 per 10,000 parts of water at each water change, to assess its efficacy to improve yield by reducing the incidence of pests and diseases in aquaculture. Juveniles of catfish were stocked at the rate of 50 per 1.4m x 1.1m x 1.1m concrete ponds. The treatment constituted of 3 ponds treated to EMAS, EMAS +EM5 and no treatment (control), respectively. Average length and weight of fish were taken 4 weekly for 20 weeks. Results showed that generally fish weight and lengths were higher in treated ponds than the untreated ponds. At 20 weeks, the ponds treated with EMAS+EM5 had significantly higher weights than the untreated at 1.9kg average weight over 1.6kg in the control. The fish in ponds treated with EMAS+EM5 and EMAS increased by 237.5 and 152.1% on their initial weights. At a table size of 1.0kg, the treated ponds could be harvested at 16weeks for better profit.

Abstract: This paper emerged out of my PhD research titled functional gaps and overlaps in the implementation of integrated water resources management (IWRM) in the Hadejia Jama'are Komadugu Yobe Basin (HJKYB), Nigeria. It concentrates on two of the six functional gas identified in the research - funding and infrastructure gaps. It shows how these gaps hamper effective integrated management of water resources. The research adopts purely qualitative techniques. It combines Semi-Structured Interview (SSI) and Focus Group Discussion (FGD) in data collection. Descriptive method, SWOT analysis, Venn diagram and Force Field Analysis (FFA) are employed in data analysis. The results reveal the persistence of low funding for water resources management, paucity and dilapidation of water infrastructures, and shortage and low capacity of data management staff. It suggests....

Abstract: The good will of house to all initiative by Government has been face with serious setback due to the high cost of building materials. This is what necessitate the conducting of this research work forthe recycling and conversion of plastic and saw dust wastes into construction materials. Moreover this approach would in addition to making these materials affordable as well as promoting a hazard free environment. The First operation would be getting the amount of both plastic and sawdust to be used for the work and make necessary preparation. Plastic waste would first of all be collected, washed and then placed in a purpose made container in an incinerator system for burning using charcoal with an air blower in order to facilitate the process, this would be achieved using a temperature reader attached with the incinerator system. A simple chained lifting pulley would be used to empty the liquid content from the container in a separate place which would be mixed with sawdust and allow so as to be cooed for some time .The two constuents would be mixed together and cut in to pieces to form light weight gravels, which would be used for light weight concrete production, back fillings ,, landscaping, land fill process etc. this will be repeatedly done depending on the amount of work to be carried out, time, cost and the required quality.

Abstract: This paper examined current and future trends with change detection in temperature and rainfall in the three agro-climatic zones of Nigeria. The datasets are of Historical period of 1961 to 2000 and projection period of 2020–2099 with ensemble mean of seven different Regional Climate Models (RCMs). Three statistical change point detection techniques were adopted to identify accurate change in the climate parameters and trends at 5% significant level. The ensemble-mean evaluation performed for the historical period (1961–2000) using Centre for Research Unit (CRU) dataset revealed that the change point occurred with precipitation and temperature series in the 1970s and 1980s, while there were significant increasing trend observed with temperature in all the three climatic zones......

Abstract: Plants of medicinal importance are the treasure for meeting our future needs and will also help in resolving elements which will form the basis of new knowledge and technology. The indigenous knowledge and traditional practices of medicinal plants are vanishing fast. Himachal Pradesh, which lies in the Indian Himalaya, has a rich diversity of medicinal plants. This paper brings together existing information with the results from recent field survey based on the interactions with herbal healers, local Vaids, rural women, and old experienced informants. The present study was conducted to explore ethno-botanical diversity and importance of local plants harnessing for medicinal purposes by the local people of Panthaghati-Pujarli region of district Shimla, Himachal Pradesh, India......
