Research ArticleOpen accessIn the abstractAlternative Monitoring Approach for IPTVAngel Ignatov, Hristo Toshkov Hristov, Jan Latal et al.IPTV emerged in the late 1990s as a solution for delivering Video on Demand (VoD) and live television over managed networks. Its widespread adoption accelerated after the expansion of broadband internet and the introduction of web technologies such as HTML5 and adaptive streaming protocols (MPEG-DASH and HLS), which enabled television content to be streamed directly through web browsers. Across Europe, … …Journal of Computer Science, Vol. 22, Issue 11 · 8 Oct 2026 · 430 accessesView PDFCite
Review ArticleOpen accessIn the abstractThe Synopsis of Environmental Heavy Metal PollutionAnyiam N. Donald, Pene B. Raphael et al.Heavy metal pollution continues to be a serious problem in the environment due to uncontrolled pesticide use, mining, foundry operations, smelting, fossil fuel burning and sewage sludge dumping. Mercury, lead, chromium, cadmium, copper and other heavy metals are non-biodegradable and remain in the environment in regions where human activity is prevalent. Heavy metal contamination is a serious hazard to all … …American Journal of Environmental Sciences, Vol. 18, Issue 5 · 7 Dec 2022 · 8,323 accessesView PDFCite
Research ArticleOpen accessIn the abstractWater Quality in Small-Scale Coffee Production Units, Amazonas, PeruEli Morales Rojas, Segundo Chávez Quintana, Magali García et al.The objective of this research was to determine water quality in small-scale coffee production units in the Amazon Region, Peru. The characterization of the factors associated with coffee farmers was collected through surveys. The Standard Methods for the Examination of Water and Wastewater (APHA) method was used to determine the physicochemical and microbiological parameters of the incoming water (AE) (water … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 11 Oct 2022 · 6,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractPollution Risk Analysis of Heavy Metals at Illegal Mining Sites at Atiwa East District, GhanaSamuel Wiafe, Sarah Fanny Hackman Duncan, Boakye Ebenezer, Samuel Yeboah BaakoThis study aims at determining the level of pollution of heavy metals (Cr, Cu and Hg) in the soils of illegal mining sites in Atiwa East District of Ghana. The concentrations of Copper (Cu), Chromium (Cr), and Mercury (Hg) in the soils were determined using Atomic Absorption Spectrometry (AAS). The extent of heavy metal pollution and pollution risk assessment was … …Current Research in Geoscience, Vol. 12, Issue 1 · 2 Jun 2022 · 10,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of a Multi-Metal Resistant Bacillus cereus Strain TWSL_5 and it’s Bioremediation Potential for Cr, Pb, Zn and FeWeerasingha Mudiyanselage Nilmini Hasintha Kumari, Naduviladath Vishvanath Chandrasekharan, Champika Dilrukshi WijayarathnaAn effluent sample collected from a textile dyeing factory was screened to isolate metal resistant endogenous bacteria using standard microbiology techniques. A bacterium with the highest metal resistance was characterized by 16S rRNA gene sequencing and the bacterial genome was screened for any possible metal resistant genes using the Polymerase Chain Reaction (PCR). The bioremoval ability of the isolate was … …American Journal of Environmental Sciences, Vol. 17, Issue 3 · 15 Jul 2021 · 6,443 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Heavy Metals Contamination in Controlled and Uncontrolled Landfill Soil, Ouagadougou, Burkina FasoBambara Telado Luc, Doumounia Ali, Kohio Nièssan et al.The study was conducted to evaluate the concentrations of heavy metals in landfill soils. The soils samples were collected in some selected landfill, at Ouagadougou. Determinations of heavy metal concentrations, calculation of contamination factor and pollution load index of heavy metal in landfill soil were undertaken. The atomic absorption spectrophotometer was used to determine the concentrations of heavy metals (Cr, … …American Journal of Environmental Sciences, Vol. 16, Issue 4 · 2 Sep 2020 · 7,311 accessesView PDFCite

Research ArticleOpen accessIn the abstractInvestigating Bio-Char as Flow Modifier and Water Treatment Agent for Sustainable Pavement DesignRenaldo Walters, Shamim A. Begum, Elham H. Fini, Taher M. Abu-LebdehThe life expectancy of Asphalt Binder (AB) has been negatively impacted by the harsh bombardment of Ultraviolet (UV) rays. UV rays cause asphalt to oxidize faster, which results in the deterioration of asphalt's rheological characteristics that can lead to pavement distresses. This paper investigates merits of bio-char to improve asphalt aging susceptibility by blending one control binder (PG 64-22) and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 9,049 accessesView PDFCite
