Research ArticleOpen accessIn the abstractEvaluation of the Effects of the Addition of Salt, Type of Additive and the Shelf Life, on Chemical Composition of Pennisetum purpureum (Schumach) (Maralfalfa) Silages in NigerMaman Lawal Abdoul Aziz, Seydou Korombé Hamza, Djibo Ibrahim et al.Seasonal variations in the quantity and quality of fodder constitute an obstacle to the development of ruminant breeding in Niger. This is why this study was carried out to evaluate the effects of salt addition, shelf life, and type of additive on the chemical composition of Pennisetum purpureum Schumach (Maralfalfa) silages. These aspects were retained because salt, in addition to … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 12 Sep 2024 · 4,720 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Variability of Indonesian Throughflow in Sumba Strait and Its Linkage to the Climate EventsAhmad Bayhaqi, Yueng-Djern Lenn, Dewi Surinati et al.As one of the Indonesian Throughflow (ITF) outflow passages, the Sumba Strait is a meeting point for the Pacific and the Indian Ocean water mass. In order to study the long-term variability of ITF flowing via Sumba Strait, this research uses observational data from the Ekspedisi WIdya Nusantara (EWIN) research cruise conducted in August 2016 to validate the altimetric geostrophic … …American Journal of Applied Sciences, Vol. 16, Issue 4 · 12 Jun 2019 · 8,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeather Parameters Impact on Daily COVID-19 Transmission in BangladeshMd. Humayun KabirCOVID-19 disease causes millions of human deaths and huge economic losses throughout the world. To limit the disease transmission numerous attempts have been made. Several studies observed associations of weather values on COVID-19 transmission. In the current study, the impacts of weather parameters on daily COVID-19 incidences have been examined in eight different cities in Bangladesh. For this purpose, a … …American Journal of Environmental Sciences, Vol. 19, Issue 3 · 30 Dec 2023 · 5,405 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining the Hazardous Medical Waste Generation Rates of Private Health Care Facilities-Case Study from Dhaka City of BangladeshMd. Yousuf Rumi, Rezaul KarimMany developing countries are lagging behind the developed countries to properly manage their hazardous healthcare waste. These waste pose a significant epidemiological risks to the general people. To estimate the epidemiological risks and to establish parameters of any waste management plan, quantitative estimation of healthcare waste generation is essential. Most researches on quantitative estimation of healthcare wastes to date, have … …American Journal of Environmental Sciences, Vol. 14, Issue 4 · 25 Apr 2018 · 8,387 accessesView PDFCite

Research ArticleOpen accessIn the abstractStable Nitrogen Isotopic Changes in Winter Wheat (Triticum aestivum L.) Induced by its Growth TemperatureZhou Feng Wang, Wei Guo Liu, Rui Juan HaoThe nitrogen dynamics of plants can be quantified using the variation in their δ15N level. This reveals details of plant physiological characteristics and the relationship between plants and their growth conditions. To better understand plant nitrogen dynamics and the effects of external temperature changes on their nitrogen isotopic composition, we investigated the δ15N characteristics in Triticum aestivum and its mother … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 1 · 21 Mar 2017 · 8,119 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Diurnal Variation of Dissolved Oxygen in a Eutrophic Polymictic ReservoirAnusha BalangodaTo evaluate the diurnal and seasonal Dissolved Oxygen (DO) variations and their effects on water quality, a comprehensive study was conducted in a eutrophic polymictic reservoir under artificially aerated and non-aerated conditions. The effect of aeration among sampling locations and along the water column of DO and DO saturation and diurnal variation of DO, water temperature, pH and conductivity was … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 24 Jan 2017 · 8,068 accessesView PDFCite
