Research ArticleOpen accessIn the abstractAssessment on Biocides Bioaccumulation in Mullet Liza klunzingeri in Kuwaiti Waters, off the Arabian GulfA.H. Bu-Olayan, B. V. ThomasBiocides, such as formaldehyde (HCHO), sodium hypochlorite (NaOCl) and glutaraldehyde (C5H8O2) that are commonly used in thermal, desalination and power plants and industries were tested on the commercially important mullet fish, Liza klunzingeri to determine the environmental contamination in the stressed ecosystem of Kuwait Bay sites. Multi-factor Probit analysis toxicity tests (96 h) on L. klunzingeri showed the lowest observed … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,768 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSpatial-Dynamics of Trace Metals Accumulation and Physicochemical Characteristics in Ikpukulu-Ama Creeks, Rivers State, NigeriaDavies Ibienebo Chris, Khang Wen Goh, Davies Imachrist Ibienebo et al.The study examines the spatial-dynamics variability of water parameters and trace metal concentrations between January and June 2023 at the Ikpukulu-Ama sites of the Bonny River, Nigeria. Key parameters analyzed include temperature, salinity, pH, transparency, dissolved oxygen, and trace metals (Ni, Pb, Cd, Cu, Zn) across three sites. The highest temperature, 32.56°C, was recorded at Site 2, indicating potential thermal … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 29 Jul 2026 · 494 accessesView PDF Cite

Review ArticleOpen accessAll words, across the recordUnraveling the Mechanisms of Plant Structural Defenses against Insect PestsAroni Preya Biswas, Roksana Al Nafiu Insha, Md. Khairul Mazed et al.Plants employ a variety of physical, chemical, and genetic strategies to defend against herbivore attacks. These biochemical defense mechanisms are complex and dynamic, encompassing both direct and indirect responses. Defense-related chemicals, whether constitutive or induced by herbivore damage, significantly influence herbivore feeding behavior, growth, and survival. Plant defense systems impact herbivore nutrition, development, and survival, highlighting the importance of chemical … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 7 Jan 2025 · 5,793 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSeasonal Variations in Semen Quality of Pasundan Bulls in their Native Tropical EnvironmentNurul Isnaini, Tri Harsi, Anggit Damaratri Lapoliwa et al.The success of artificial insemination highly depends on the semen quality, in which it may significantly associate with the environmental factor. However, the information regarding the seasonal effects on semen quality of Pasundan bulls is still scarce. This study aimed to examine seasonal variation in semen quality of Pasundan bulls in their native environment. A total of 203 ejaculates produced … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 27 Apr 2021 · 7,931 accessesView PDF Cite

Review ArticleOpen accessAll words, across the recordA Strategic Study on the Environmental Impacts of Wind Turbine Blade Materials, their Improvements, Economics and End-Life-OptionsOjshwi Prakash, Godwin Glivin, N. Kalaiselvan, V. MariappanWind energy is a great alternative to solar energy (During monsoon) along with conventional non-renewable energy sources and has a potential market growing exponentially. Modern 3 Blade HAWTs are most dominant in the market and have high efficiency. Blades are 15 to 20% of the cost of the wind turbine unit and also exposed to the environment. Therefore it is … …Energy Research Journal, Vol. 11, Issue 1 · 13 Nov 2020 · 8,366 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDegradation of High Voltage Polymeric Insulators in Arid Desert's Simulated Environmental ConditionsYasin KhanProblem statement: High Voltage (HV) polymeric insulators are replacing ceramic insulator commonly used for HV outdoor networks due to their ease of handling, reliability and cost. However, their long term performance and reliability are major concerns to power utilities. Approach: To investigate their performance in arid desert's conditions, two types of HV composite insulators were aged as per International Electrochemical … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,098 accessesView PDF Cite
