Research ArticleOpen accessIn the abstractIn vitro Polyploid Induction in Phalaenopsis Aphrodite by PendimethalinPrasetyorini Djarot, Deden Sukmadjaja, Fadya Annisa Chaesarani, SukonoPhalaenopsis aphrodite is a type of orchid with high ornamental and economic value. However, its development for commercial needs in Indonesia is still hindered by the limited availability of varieties. Therefore, enhancing genetic diversity is necessary, one of which is through polyploid induction. Several previous studies reported that pendimethalin effectively duplicates the chromosome numbers of various plant species. The aim … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 22 Aug 2026 · 854 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimalization of the Swim-Up Method for Bali Bull Sperm: Effect of Incubation Time and Medium on Sperm KineticsAthhar Manabi Diansyah, Muhammad Yusuf, Rahmat et al.Bali bulls (Bos javanicus) are an essential part of Indonesia’s indigenous livestock, prized for their ability to thrive in challenging environments, their natural disease resistance, and their strong reproductive capabilities. The aim of this study was to refine the swim-up technique for preparing Bali cattle sperm. We evaluated the effects of two commonly used media Tyrode's Albumin Lactate Pyruvate (TALP) … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 9 Feb 2026 · 1,687 accessesView PDFCite
Research ArticleOpen accessIn the abstractColiforms Diversity and Antibiotic Resistance in Kazakhstan CheeseAnar Kuzeubayeva, Altay Ussenbayev, Ali Aydin et al.Coliform bacteria contaminate dairy products and pose public health concerns including food poisoning and toxemia. We aimed to determine the species diversity of coliforms and to evaluate the resistance to antibiotics of E. coli in various types of cheese sold by local producers in Kazakhstan. We collected 197 samples from different cheeses sold by producers in the Kostanay (n = … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 22 Feb 2024 · 5,993 accessesView PDFCite
Research ArticleOpen accessIn the abstractRadiosensitivity Assessment and the Impact of Gamma Radiation on the Growth and Diversity of Pennisetum purpureum Cv Mot in Marginal LandBela Putra, Budi PrasetyaThis study aims to assess the radiosensitivity of Pennisetum purpureum cv Mott, with the primary objectives of determining the LD50 value, evaluating the effects of gamma radiation doses on plant growth and diversity, and elucidating the specific goals of irradiation in relation to the overall research. The research encompasses a wide range of radiation doses, ranging from 0-400 Gy, including … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 20 Dec 2023 · 5,641 accessesView PDFCite
Research ArticleOpen accessIn the abstractResistance to Brown and Stem Rust in Spring Soft Wheat Varieties in the Arid Climate of Northern KazakhstanAdylkhan Babkenov, Sandukash Babkenova, Svetlana Dashkevich et al.To create competitive wheat varieties, it is essential to make active use of the world's diversity of genetic resources. The study aims to test the genetic resources of spring soft wheat for resistance to rust diseases. A spring soft wheat collection consisting of 206 samples, was studied in 2020-2022 for resistance to leaf and stem rust, as well as for … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 28 Aug 2023 · 5,023 accessesView PDFCite
Research ArticleOpen accessIn the abstractBroodstock Formation and Sterlet (Acipenser ruthenus) Reproduction in the West-Kazakhstan RegionGuldana Maratkyzy Maratova, Kuanysh Isbekov, Shokhan Alpeisov et al.A dramatic decline of sturgeons’ stocks including the sterlet (Acipenser ruthenus) in the Caspian Sea including creates the need to establish aquaculture broodstock. Broodstock management can allow conserving the gene pool of the sterlet and the creation of captive broodstock further serve as a source of sterlet fry aimed at restoring natural populations of the sterlet in the Caspian Sea. … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 11 Jul 2023 · 5,321 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Background Knowledge and Random Sampling in Genetic Programming: A Case Study in Learning Boolean Parity FunctionsLappoon R. TangThe Boolean even-N-parity function returns T (i.e., true) if an even number of its Boolean arguments for N arguments are T and otherwise returns NIL (i.e., false). Learning Boolean even-N-parity functions has been recognized as a difficult problem for evolutionary computation (such as genetic programming) especially when N is large (e.g., 20+). A number of approaches have been proposed for … …Journal of Computer Science, Vol. 19, Issue 7 · 10 Jul 2023 · 5,481 accessesView PDFCite
