Research ArticleOpen accessIn the abstractSuperovulation Response and Embryo Quality Recovered Following Flushing Nguni Heifers and CowsAyanda Maqhashu, Masindi L. Mphaphathi, Pokgedi J Sebei et al.The aims of the study were to compare super ovulatory response, fertilization rate and evaluate embryo quality recovered from super ovulated Nguni stud cows and heifers. Nguni cows (n = 15) and heifers (n = 10) aged 4-6 and 2 years, respectively, were used as embryo donors. Embryo donors were synchronized for estrus before superovulation. For superovulation donors were administered … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 25 Nov 2021 · 6,431 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Production of Anhydrous Bioethanol using Glycerol and 1-Butyl-3-Methylimidazolyl-Tetrafluoroborate in the Aspen Plus SimulatorJosé Izaquiel Santos da Silva, Lílian da Silva Félix, Mariana Martins Vieira et al.Biofuels are present in the global scenario as an energy source derived from organic biomass, representing an economic and environmental alternative. They are a renewable source of energy with low rates of pollutants emissions and, consequently, less carbon dioxide is released into the atmosphere. The obtaining of bioethanol is originated from a fermentation process, in which a multi-component mix is … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 16 Jun 2021 · 7,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular-Biological Properties of the Attenuated Strain of Salmonella Abortus-Equi E-841, used in the Creation of a Vaccine against Abortion of MaresAssiya Mussayeva, Natalya Yegorova, Merey Yerishov et al.Salmonella abortion of mares takes a leading place in the in factious pathology of horses and leads to the abortion of pregnant mares and infected stallions become salmonella carriers. The disease with salmonella abortion manifests itself in the last months of pregnancy, maybe-during the mass foal of mares-in the spring. The article results obtained of studies on the biological properties … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 28 May 2021 · 7,120 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Al based Composites Reinforced with FeAl Intermetallic Particles by Mechanical AlloyingSergio Rubèn Gonzaga Segura, Arturo Molina Ocampo, Renè Guardián Tapia, Alejandro Sedano AguilarIn this research project, Al matrix composite materials reinforced with 5 and 10 (wt. %) of FeAl intermetallic particles were synthesized by Mechanical Alloying (MA) at a speed of 250 RPM for 2, 5, 10 and 15 h of milling time. The results showed that composite materials can be obtained at low energy conditions with improved dispersion of the reinforcement … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 24 Mar 2021 · 6,886 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Different Freezing Curves on the Acrosome Integrity of Male Goat Sperm CellsSofia Alexandra Fagundes Lopes, Henrique José Duarte Rosa, António Chaveiro, Fernando Moreira da SilvaThe aim of the present study was to evaluate the effect of three different freezing curves on male goat’s sperm viability and acrosome integrity. Semen was collected on three adult male goats in February (Azores, Portugal, latitude 38°39′N) using an artificial vagina and a female with induced heat. Three collection sessions were spaced of approximately 5 days. The study followed … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 19 Feb 2021 · 6,616 accessesView PDFCite

Two critical areas with high traffic demands were identified through the collected traffic data at the major intersections in these areas., These areas were Kuwait City (near the ministries area) and Al-Blajat street (known as the … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 24 Jan 2021 · 7,059 accessesView PDFCite
Research ArticleOpen accessIn the abstractSperm DNA Fragmentation and Apoptosis Levels: A Comparison of the Swim up and the Density Gradient Centrifugation Methods for Sperm PreparationSilvia W. Lestari, Triyana Sari, Dwi A. PujiantoThis study investigated the efficiency of two sperm preparation methods, namely, density gradient centrifugation and the swim-up method, in selecting spermatozoa based on the DNA fragmentation index and the apoptosis levels. Fifteen semen samples from infertile couples underwent sperm preparation in this study. The Makler® counting chamber and Eosin Y staining were used to analyse the sperm concentration, motility and … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 14 Nov 2016 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractPassage Effect on Aging of Human Umbilical Cord Derived Mesenchymal Stem CellDian Mediana, Isabella Kurnia Liem, Jeanne Adiwinata Pawitan, Noviyanti GoeiTo be used in regenerative medicine, cells should be checked for various conditions, including cell aging. This study aimed to learn senescent profile and its relation to cell viability, proliferation and cell size in various passages, which were done in α-MEM-10% PRP medium, until senescence-associated β-galactosidase (SA-β-Gal) positive cells were found. Stem cells were isolated from umbilical cord tissue by … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 31 Jul 2015 · 8,039 accessesView PDFCite
