Research ArticleOpen accessIn the abstractProduction of Selenium-Enriched Yeast (Kluyveromyces marxianus) Biomass in a whey-based Culture MediumNicolás Gurdo, Mario Calafat, Diego Gabriel Noseda, Isabel GigliTwo important aspects of agriculture intensification are the reduction in the concentration of specific soil minerals that affects livestock production and the increase of agricultural by-products, which produce environmental pollution. In this regard, whey - a cheese by-product-often is considered a wasted-product. Due to its lactose concentration, (4.5%), when whey is discarded without treatment generates a high Biological Oxygen Demand … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 28 Jun 2018 · 11,375 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantitative Analysis of the Pb Concentration in Dust Fall in Zahedan in the Winter of 2014Sara Abdollahi, Akram Karimi, Meysam Madadi et al.Dust is considered as one of the atmospheric phenomena that inappropriately influences the environment. Falling dust contains particles with the size of 100 microns or less, which falls from atmosphere on the surface of the earth. This study aimed at determining the Pb concentration in falling dust samples in order to investigate the urban pollution caused by this element. To … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 11 May 2018 · 7,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Chlorophyll-an in a Small Reservoir by Landsat 7 ImageryMaryam Ghashghaie, Kaveh Ostad-Ali-Askari, Saeid EslamianChlorophyll-a (chla) is a source of water pollution. Monitoring the quality of water in reservoirs is necessary to take any action for protecting the water quality. Traditional methods of sampling are usually costly and time consuming. Also they need skillful labors and some areas are out of reach or sampling at those areas is dangerous. Remote sensing technology could solve … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 Apr 2018 · 8,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption and Distribution of Selected High Molecular Weight Polycyclic Aromatic Hydrocarbons in a Typical Coastal Sand DepositUzoije Atulegwu Patrick, Ezenobi Chukwunoye ChristainContaminant migration study through soil medium is a veritable tool for a match towards sustainable groundwater protection. It is also essential to predict the fate and Transport of pollutants and to evaluate pollution risks. In this study, migration and distribution of High Molecular Weight (HMW) Polycyclic Aromatic Hydrocarbons (PAHs) through a coastal sand deposit of a wetland was investigated. Flow … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 27 Mar 2018 · 7,360 accessesView PDFCite
Research ArticleOpen accessIn the abstractUncertainty Analysis of Time of Concentration Equations based on First-Order-Analysis (FOA) MethodAsghar AzizianThe time of concentration (Tc) is one the most important time parameters to predict the response of a catchment to a given rainfall and plays a key role in the hydrologic design and rainfall-runoff modeling. There are a huge number of empirical/semi-empirical equations for estimation of Tc and depending on several parameters such as rainfall attributes, topographic and land cover … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 19 Mar 2018 · 9,294 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Effects of Landfill in Azad-Shahr City on the Physicochemical Properties of GroundwaterSara Abdollahi, Safieh Javadinejad, Kaveh Ostad-Ali-Askari, Vijay P. SinghLocations near landfills have a lot of potential for contamination of groundwater, because there is a high potential for contamination with emulsion in these areas. In this study, the quality of physic chemical and carbon-organic materials (TOC) of water wells around landfill of Azad-Shahr city was investigated. To accomplish this purpose, sampling of water from seven deep wells around the … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 3 Jun 2019 · 7,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Analysis of Bifidobacteriaceae in a Fermented Milk and Colostrum Product in Relation to Immune FunctionMarco RuggieroThis study investigates the microbial composition of a commercially available Swiss fermented milk and colostrum product with a history of use in chronic condition management since 2014. The analysis, performed using the Axiom Microbiome Array, identified a high number of targets corresponding to microbial species classified as probiotics belonging to the Bifidobacteriaceae family. The array provided 28 unique targets, each … …American Journal of Immunology, Vol. 19, Issue 1 · 2 Aug 2024 · 9,049 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Static Magnetic Field Exposure in Obese Mice Induced by High Fat Diet: Its Effect on T-Box15 Gene and Uncoupling Protein 1 ExpressionWidia Bela Oktaviani, Puji Sari, Luluk Yunaini et al.Increased Ca2+ cytosolic concentration caused by Static Magnetic Field (SMF) exposure modulates Tbx15 protein and Ucp1 gene interaction that is involved in the thermogenesis browning process of white adipose tissue. Activation of Tbx15 as a transcription factor that regulates the expression of the Uncoupling protein 1 (Ucp1) gene induced by SMF exposure in adipose tissue converts excess accumulated fat into … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 23 Jan 2024 · 4,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractSupplementation of Prill Fat Derived from Palm Oil on Nutrient Digestibility and Dairy Cow PerformanceLolita Udin Riestanti, Despal, Yuli RetnaniPrill fat is a hydrogenated vegetable oil which contains more than 85% palmitic acid with a high melting point. Due to this reason, it does not melt at rumen temperature and bypass rumen degradation. This study was aimed to determine the optimum level of prill fat (86% palmitic acid) supplementation in dairy ration on fermentation characteristics, feed digestibility, milk production, … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 1 Jul 2021 · 8,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractExogenous Progesterone for Offspring Sex Ratio Manipulation in Arabic Chickens (Gallus turcicus) Leading to Increasing Female Chicks ProportionIswati, Muhammad Halim Natsir, Gatot Ciptadi, Trinil SusilawatiFemale birds of egg-laying hens are more valuable than males, because males bird have no commercial value. The opportunity to manipulate offspring sex ratio in poultry has been observed in female birds; hence, female birds have heterogametic ZW chromosomes. High progesterone concentration 2-5 h before ovulation is thought to affect the segregation of female sex chromosomes as the basis for … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 17 Feb 2021 · 7,500 accessesView PDFCite
