Research ArticleOpen accessIn the keywordsUltra Wide Band (UWB) Ad-hoc Networks: Review and TrendsRashid Saeed, Sabira Khatun, Borhanuddin M. Ali, Mohd K. AbduallahShort-range wireless systems have recently gained a lot of attention to provide seamless, multimedia communications around a user-centric concept in so called Wireless Personal Area Networks (WPAN). Ultra-Wide Band (UWB) technology presents itself as a good candidate for the Physical Layer (PHY) of WPAN, both for high and low data rate applications. Many ongoing developments of Ultra-Wide Band (UWB) system … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 7,060 accessesView PDFCite
Research ArticleOpen accessIn the keywordsQuality of Service Policy for IEEE 802.11 Networks with Service Rate Selection based on Fairness IndexLia Toledo Moreira Mota, Alexandre de Assis Mota, Luis Fernando FontolanProblem statement: The IEEE802.11 standard states that all stations have the same probability of accessing the network, but does not consider important parameters such as transmission rates and signal-to-noise ratios. However, these networks present an anomaly that allows a station with a low transmission rate to use the communication channel for a long time. Approach: In this context, this study … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,660 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Methyl Jasmonate and Plant Growth Promoting Rhizobacteria (PGPR) on Antioxidant Potential and Metabolomic Profiles of Zingiberaceae RhizomesHenny Lieke Rampe, Hanny Hesky Pontororing, Hanry Jefry Lengkong et al.The rhizomes of Zingiberaceae plants are used as cooking spices, medicines, cosmetics and beverage ingredients. Zingiberaceae rhizomes have the potential to be immunostimulants, antioxidants and immunomodulators. Antioxidants are chemical compounds that bind free oxygen radicals and prevent free radicals from damaging healthy cells. This research aimed to analyze the antioxidant potential and metabolomic compounds of the rhizomes of the Zingiberaceae … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 10 Apr 2026 · 1,311 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphology of Female Adult Black Soldier Fly Under Slaughterhouse Waste and Rice Bran Growing MediumFadilla Rizkia Fasha, Dedes Amertaningtyas, Faizal Andri, Nurul IsnainiThe effectiveness of Black Soldier Fly (BSF) farming within a sustainable waste management framework heavily depends on the choice of a suitable rearing substrate. This study aimed to assess the morphological characteristics of female adult BSF reared on growing media composed of slaughterhouse waste (SW) and rice bran (RB). This study was conducted at the Laboratory of Animal Reproduction, Faculty … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 4 Dec 2025 · 2,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractMarine-Derived Extracts as Economically Sustainable and Ethical Alternatives to Fetal Bovine Serum in HEK293 Cell CultureKian Kenneth Francisco Sanchez, Jennifer Seki-Wong et al.Fetal Bovine Serum (FBS) is a staple supplement in cell culture, providing key growth factors that promote cell health and proliferation. Since 1885, cell culture has been a cornerstone of both basic and applied research, leading to significant discoveries of cell communication and function. However, the use of FBS presents economic and ethical challenges. Millions of bovine fetuses are euthanized … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 7 Aug 2026 · 1,042 accessesView PDFCite
Research ArticleOpen accessIn the abstractHepato and Nephrotoxicity Caused by Sub-Chronic Exposure to Relevant Concentrations of Human Exposure to Glyphosate-Based Herbicide: An Experimental Study in RatsFernanda de Maria Serra, Letícia Rocha Magalhães, Beatriz Bertholace Magalhães Silva et al.Glyphosate's remarkable effectiveness in weed control has made it among the foremost widely employed herbicides globally. Several Glyphosate-Based Herbicides (GBHs) contain 1-4 dioxane, a compound known to induce cancer in animals and potentially contribute to liver and kidney damage in humans. The objective was to assess the liver and kidney toxicity resulting from sub-chronic exposure to GBH in rats. Eighty … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 26 Dec 2023 · 5,194 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of the Degree of Soil Salinity and the Bio preparation on Productivity of Maize in the Shaulder Irrigated MassifMaksat Nurbaiuly Poshanov, Shakhislam Uzakbaevich Laiskhanov, Zhassulan Maratovich Smanov et al.During the study on the Shaulder irrigated massif, the soil salinity maps with different degrees of salinity were compiled at the large-scale 1:10000 in the GIS environment. It was found that the area of saline soils increases with depth. In the upper 0-20 cm layer, 29% is salted and in the 50-100 cm layer, up to 44% is salted. The … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 11 Feb 2022 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Adding Cellulose on Lipid Accumulation in Cellobiohydrolase and Delta-6 Desaturase Engineered Mucor circinelloides StrainsYao Zhang, Yanxia Wang et al.Despite microbial production of multifunctional gamma-linolenic acid (GLA) being an important and promising way, the high cost is still a major factor limiting industrial applications. Previously, we proposed a novel approach to promote the production of GLA from cellulose, a widely available and cheapest resource, by overexpression of the cellobiohydrolase (CBH2) and delta-6 desaturase (D6) in Mucor circinelloides. In the … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 13 Oct 2023 · 4,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent Traffic Light System Using Convolutional Neural Network to Optimize Vehicle Flow in IndonesiaBhustomy Hakim, Fergie Joanda Kaunang, Yemima Monica Geasela, Regina HillaryTraffic congestion remains a persistent challenge in major Indonesian cities due to rapidly increasing vehicle density and the continued reliance on fixed-time traffic signal scheduling. This study aims to develop an intelligent traffic light system that dynamically adjusts sequencing based on real-time road conditions. A dataset of 902 CCTV images was collected from intersections in six large cities across Indonesia, … …Journal of Computer Science, Vol. 22, Issue 2 · 17 Feb 2026 · 2,155 accessesView PDFCite
