Item type:Item, A Web-Based Aggregate Information Portal(EJECE, European Journal of Electrical Engineering and Computer Science, 2021-05-12) Bayem,Donatus.I; Osuagwu,Henry.OA Web portal aggregates an array of information for a target audience and affords a variety of services including search engines, directories, news, e-mail, and chat rooms, and they have evolved to provide a customized gateway to Web information. Also, a high level of personalization and customization has been possible. The portal concept could further be established to function as a classy Web interface that can serves as sustenance for variety of the task performance. The aggregate information Web portal will serve as portals for the information needs of users on the web. The Web based portal enable marketing of users broadly across a wide variety of interests. Most of the popular usage of the Web based aggregate information portal probably refers to the visual and user interface (UI) design of a Web site. It is a crucial aspect since the visitor is often more impressed with looks of website and easy to use rather than about the technologies and techniques that are used behind the scenes, or the operating system that runs on the web server. In other words, it just does not matter what technologies that is involved in creating, when the site is hard to use and easy to forget. This paper explores the factors that must be painstaking during the design and development of a Web based aggregate information portal. Design as a word in the context of a Web application can mean many things. A working Web based aggregate information portal, kaseremulticoncept was developed to support the various users’ task performances. A number of technologies was studied and implemented in this research, which includes multi-tier architecture, server and client side scripting techniques and technologies such as PHP programming languages and relational databases such as MySQL, Structured Query language (SQL) and XAMPP Server.Item type:Item, EFFECTS OF WATER TURBIDITY ON HUMAN HEALTH A STUDY OF GBARAMATU KINGDOM IN WARRI SOUTH – WEST, DELTA STATE - NIGERIA(BERKELEY PUBLICATION AND RESEARCH INTERNATIONAL, 2020-12-31) Ayuba KaluriThis paper examines the effect of water turbidity on Human Health in Gbaramatu Kingdom. Turbidity in water is a measurement of how cloudy or murky a body of water is. It also measures the cloudiness of water and indicates water quality and filtration effectiveness. Turbidity is caused by particles of soil, organic matter, algae, metals, or similar matter suspended in the water column. These particles scatter light and make the water appear cloudy or murky. Secchi Disc (SD) is used to measure the amount of water turbidity. Bore-holes, sea and rain water are the major sources of water here. Higher turbidity level is often associated with higher level of diseases-causes micro organisms such as viruses, parasites and some bacteria. These organisms can cause symptoms like vomiting, dizziness, skin rashes and lung irritation. Most of the cholera, and enteric fever prevail due to unsafe drinking water clubbed with the environmental factors. Many of the diseases caused by the human consumption of impure water are preventable if proper health and sanitation standards are enforced. Effort should be put in place by the Government to ensure the provision of treated, safe and quality drinking water such as drilling of bore-hall. Well and Bore-hall water which serve as the sources of water should be treated. Water Safety Plan (WSPs) should be used to monitor sources of water quality, the effectiveness of coagulation and clarification, filtration and disinfection performance in a water treatment plant, and the effectiveness of distribution system management. diseases such as diarrhea, dysentery,Item type:Item, Evaluation of Heavy Metal Pollution in Farm Soil and Irrigation Water in Yamaltu Deba Gombe State, Nigeria(Journal of Energy Technology and Environment, 2025-06-06) Jalo Enock; Ayuba Kaluri; Mayi MagdaleneHeavy metals concentration is worrisome because of its accumulation in the soil, water and food substances. It poses a great threat to human and animals such as lung cancer, liver damage and gastrointestinal distress. Therefore, this study was aimed at investigating the level of heavy metals in farm soil and irrigation water in Yamaltu Deba Gombe State. Samples were appropriately stored, preserved and treated before they were transported for laboratory analysis. Results obtained from the laboratory analysis were analyzed using Microsoft Excel 2013. The mean values were subjected to one-way analysis of variance (ANOVA) at 95% confidence level. The results of this study revealed that the accumulation of heavy metals in farm soil and irrigation water shows the concentration of cadmium, Chromium, Lead, Arsenic, Cobalt, Iron and Cupper were significantly below the WHO permissible limit except for Manganese that recorded highest value in all the sampling point. The results were above the permissible limit. Water samples were also analyzed to determine the accumulation of heavy metals concentrations. Cadmium, Chromium, Lead, Arsenic, Cobalt, Iron and Cupper was found to be in a range of 0.11 to 0.083. The high concentration was recorded at Kunji normal and the lowest in Kanawa control. Even though, they were below the permissible limit of 0.1. Cadmium was undetected in all samples obtained from Kwadom control, Poli normal as well as Poli control. Manganese has highest value above the WHO Permissible limit. In analyzed soil samples, the moisture content, pH, electrical conductivity, cation exchange capacity, and organic matter were found below the permissible limit, except electrical conductivity and organic matter were found to be above the limit. It can be recommended that soil in the study area is good for crop production, the water and vegetables are safe for drinking and consumption.Item type:Item, A Survey on AI-Driven Strategies and Solutions for Environmental Conservation(Journal of Energy Technology and Environment, 2025-03-12) Ayuba Kaluri; Jalo Enoch; Mayi MagdaleneThe study examines A Survey on AI-Driven Strategies and Solutions for Environmental Conservation: Insights from Conservation Professionals. The study focused on professionals and organizations working in environmental conservation and AI which includes World Wildlife Fund, Environmental Defence Fund, Ministry of Environment, National Environmental standards and Regulations Enforcement Agency, National Centre for Energy and Environmental, Nigerian Institute for Oceanography and Marine Research. A random sampling method was used for the selection of the respondents. The sample size were 200 respondents. Structured questionnaire was used for the collection of data. Descriptive statistics of mean and standard deviation was used to answer the research questions while the Inferential Statistics of Chi-square was used to test the hypotheses at 0.05 level of significance. The results revealed that, AI-driven strategies significantly improve the effectiveness of environmental conservation efforts in addressing issues like deforestation and wildlife preservation and AI-driven solutions significantly perceived to have a positive impact on the sustainability and future success of long-term conservation goals. The researcher recommended that: Conservation organizations and government agencies should allocate more funds and resources to support the adoption and development of AI technologies developing technical skills among conservation professionals is crucial for maximizing the potential of AI-driven strategies. Specialized training programs, workshops, and partnerships with technology institutions that can build the expertise required to implement and manage AI applications effectively in conservation, establishing data-sharing platforms that can enhance collaboration and knowledge exchange within the conservation community.Item type:Item, Assessment of the Level of Heavy Metals in Irrigation Water, Farm Soil, and Vegetables Grown in Gobbiya Dam, Bogoro Local Government Area Bauchi State, Nigeria.(Journal of Energy Technology and Environment, 2025-12-02) John Joseph; Toma Buba; Jalo Enoch; Ayuba KaluriThis study assessed heavy metal concentrations (Pb, Cd, Cu, Cr, As, Fe, Ni) in irrigation water, farm soil, and four vegetable species (kenaf, chili pepper, tomato, and spinach) cultivated around Gobbiya Dam, Bogoro Local Government Area, Bauchi State, Nigeria. Samples were collected from irrigation water, agricultural soil, and different plant parts (roots, stems, leaves, and fruits) and analyzed using Atomic Absorption Spectrophotometry (AAS). Results revealed significant regulatory violations in both soil and water sources, with soil chromium (0.116 mg/kg) exceeding WHO limits (0.10 mg/kg), while irrigation water showed elevated arsenic (0.014 mg/L) and cadmium (0.024 mg/L) above WHO standards (0.01 mg/L and 0.01 mg/L respectively). Soil contamination factors indicated very high contamination for both iron (CF = 10.62) and cadmium (CF = 8.30), while moderate contamination was observed for nickel (CF = 1.66) and chromium (CF = 1.16). Arsenic and lead showed low contamination levels (CF = 1.00 and 0.74 respectively), while copper exhibited the lowest contamination factor (CF = 0.08). Chili pepper demonstrated the highest heavy metal accumulation, particularly cadmium in fruits (0.295 mg/kg), exceeding WHO vegetable safety limits (0.2 mg/kg). Tomato fruits contained arsenic levels (0.055 mg/kg) matching WHO limits, while spinach showed efficient translocation of most metals to leaves. Translocation factor analysis revealed nickel as the most mobile metal across all species (TF range: 1.454 – 4.639), while bioaccumulation factors indicated significant bioaccumulation for arsenic in tomato fruits (BAF = 5.586) and cadmium in chili pepper fruits (BAF = 3.565). Leaves emerged as the primary accumulation site for iron, nickel, and cadmium across all species, while copper showed preferential root sequestration in kenaf and chili pepper. The study concludes that current agricultural practices around Gobbiya Dam pose significant food safety risks due to heavy metal contamination, with chili pepper and tomato fruits presenting the greatest concern for human consumption. Regular monitoring of irrigation water, soil, and vegetable produce for heavy metal contamination should be institutionalized, particularly in dry-season farming areas relying on dam water. Additionally, phytoremediation strategies should be adopted using crops such as kenaf, which demonstrated root retention and lower metal translocation to aerial parts, thus acting as a potential sink for toxic elements
