Research ArticleOpen accessIn the author namesGrowth Performance and Duodenal Morphometry of 1-6 Week Old Kampung Chickens Supplemented With L-LeucineCharles Venirius Lisnahan, Steffanie Merlin Clyricia Noach, Lukas Pardosi, Theresia Nur Indah KoniThis study evaluated the effects of dietary L-leucine supplementation on growth performance and duodenal morphometry of Kampung chickens during the starter phase (1–6 weeks). A total of 600 one-week-old Kampung chickens were randomly assigned to five dietary treatments with six replicates of 20 birds each in a completely randomized design. The treatments consisted of a basal diet without L-leucine (T0) … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 11 Sep 2026 · 904 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffects of Dietary Isoleucine Supplementation on the Growth Performance, Carcass Characteristics and Ileal Morphology of Native ChickensCharles Venirius Lisnahan, Oktovianus Rafael Nahak, Lukas PardosiThe roles of isoleucine in the protein synthesis, metabolisms, and growth of chicken have been widely reported. However, its effect on native chicken has not been previously reported. In this work, we reported the effects of dietary isoleucine supplementation on growth performance, carcass characteristics, and ileal morphology in native chickens during the grower phase (6-12 weeks). Two hundred native chickens … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 21 Jun 2025 · 2,940 accessesView PDFCite
Research ArticleOpen accessIn the author namesIsolation and Characterization of Superior Symbiotic Bacterial Isolates from the Oenggae Sea with Potential as AntibacterialLukas Pardosi, Adelya Irawan Manalu, Charles Venirius LisnahanSponges are one of the marine biota that have a symbiotic relationship with bacteria which can produce secondary metabolites as antimicrobials. The main aim of this research was to isolate and identify bacteria that had potential as antibacterials against multi-drug resistant test bacteria. The sponsor samples used in this research were Stylissa massa, Salvador Dali, and Angelas sp. The methods … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 26 Mar 2024 · 5,053 accessesView PDFCite
Research ArticleOpen accessIn the author namesPredicting Depression Levels using Back Propagation Neural NetworkEddy Muntina Dharma, Yaya Heryadi, Lukas et al.Depression is a mood disorder characterized by feelings of deep sadness and a sense of indifference. When depression recurs in moderate or severe intensity, it can be a serious health condition. The most effective way to deal with this problem is to predict the symptoms of depression at an early stage. In this study, a Back Propagation Neural Network (BPNN) … …Journal of Computer Science, Vol. 18, Issue 3 · 18 Mar 2022 · 6,882 accessesView PDFCite
Research ArticleOpen accessIn the author namesPerinatal Cardiovascular Evaluation in Dorper Sheep Echocardiographic Description and Behavior of the Heart Rate Variability on the FieldAmanda Sarita Cruz Aleixo, Mayra de Castro Ferreira Lima, Ana Luísa Holanda de Albuquerque et al.The heart is innervated by the autonomic nervous system, with a predominance of sympathetic and parasympathetic activity associated, respectively, with increases and decreases in the heart rate, as illustrated by the Heart Rate Variability (HRV). Pregnancy induces significant changes in the maternal cardiovascular and hemodynamic systems. This study aimed at evaluating changes in the clinical and echocardiographic parameters of pregnant … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 3 Nov 2021 · 6,518 accessesView PDFCite
Research ArticleOpen accessIn the author namesComparison of Analytical and Numerical Results for the Charring Rate of the Timber-Concrete BeamZuzana Kamenická, Jaroslav Sandanus, Lukáš Blesák et al.Modelling the thermal response of timber is a primary issue for the assessment of the mechanical resistance of timber structures exposed to fire. Therefore, this paper analyses various advanced calculation methods of determining the charring rate. Authors of this contribution use analytical calculation methods according to two different publications and also a numerical calculation by means of program based on … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 4 Jun 2018 · 6,688 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Class of Region-preserving Space Transformations for Indexing High-dimensional DataRatko Orlandic, Jack LukaszukThis study introduces a class of region preserving space transformation (RPST) schemes for accessing high-dimensional data. The access methods in this class differ with respect to their space-partitioning strategies. The study develops two new static partitioning schemes that can split each dimension of the space within linear space complexity. They also support an effective mechanism for handling skewed data in … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,919 accessesView PDFCite
