Research ArticleOpen accessIn the abstractStudy Scope of Cardiographic Diagnosis of Myxomatous Mitral Valvular Disease and Sinus Arrhythmia in Dogs and CatsIntan Permatasari Hermawan, Hana Cipka Pramuda Wardhani, PalestinMyxomatous Mitral Valvular Disease (MMVD) is the most common cardiac problem in dogs, and sinus arrhythmia in cats is important to early diagnosis. This study aimed to diagnose Myxomatous Mitral Valvular Disease (MMVD) using echocardiography and sinus arrhythmia using electrocardiography in dogs and cats. This study evaluates two dogs, a male mix domestic, and two cats, a male mix domestic, … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 27 Mar 2025 · 5,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Performance Analysis of a Petroleum-Pipeline-Pressure-Boosting Station Powered by Two-Shaft GT EngineYousef S. H. Najjar, Mohammad Z. M. Yousef, Aad M. A. Al-MahgariThis study offers modeling and performance analysis of a pressure-boosting station for petroleum pipelines using a sustainable two-shaft GT engine to drive a three-stage centrifugal pump. The modeling is divided into three steps; matching the GT engine components at the maximum efficiency line, matching the pump performance with the requirements of the pipeline system to generate the pump load curve, … …Energy Research Journal, Vol. 12, Issue 1 · 18 Jan 2022 · 10,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Peculiarities of Archips rosana, the Insect Pest of the Sievers Apple Tree (Malus sieversii) in the Trans-Ili Alatau Ridge (the North Tien Shan)Gulzhanat Tanabekova, Roman Jashenko, Zhaozhi LuThe article provides new information on the phenology of a serious insect pest, the species of Archips rosana (Linnaeus, 1758) (Lepidoptera: Tortricidae), rendering fundamental harm to the Sievers apple trees, native to the Trans-Ili Alatau region (the North Tian Shan), which was not previously covered by studies. Material for research was obtained by the authors during two field seasons 2018-2019 … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 23 Nov 2020 · 6,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Potassium Fulvic Acid and DA-6 on the Growth and Yield of Tomato Cultivated with Rock WoolXiao Huaijuan, Zhou Yan, Mao Ke et al.Potassium fulvic acid and diethyl aminoethyl hexanoate (DA-6) are two kinds of growth regulators with yield increasing and quality improving. There are few reports on the effects of adding potassium fulvic acid and DA-6 in nutrient solution on the growth of soilless culture of vegetables. In this study, tomato was used as the test material to add different concentrations of … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 7 Apr 2020 · 8,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Postoperative Brain MRI Segmentation with Automated Skull Removal and Resection Cavity AnalysisSobha Xavier P., Sathish P. K., Raju G.Brain tumors present a significant medical challenge, often necessitating surgical intervention for treatment. In the context of postoperative brain MRI, the primary focus is on the resection cavity, the void that remains in the brain following tumor removal surgery. Precise segmentation of this resection cavity is crucial for a comprehensive assessment of surgical efficacy, aiding healthcare professionals in evaluating the … …Journal of Computer Science, Vol. 20, Issue 5 · 19 Mar 2024 · 5,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomated Evaluation of Short Answers Using Text Similarity for the Portuguese LanguageSilvério Sirotheau, Joao C.A. dos Santos, Eloi L. Favero, Simone N. de FreitasAlong with the development of distance education, emerges the demand for virtual environments as the automated evaluation studies of essays that has already produced promising results. However, when dealing with short answers, replicating the decisions of a human grader is still a challenge, as the portability of essay evaluation techniques to short answers has not produced results with the same … …Journal of Computer Science, Vol. 15, Issue 11 · 21 Nov 2019 · 6,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Edge Efficient and Lightweight Hybrid CNN Vision Transformer Network With CBAM for IoT Based Plant Disease DetectionNyabeye Pangop Doris-Khöler, Kengni Ngangmo OlgaDetecting crop disease early enough to act on it remains a bottleneck for smallholder and precision farming alike, particularly when diagnosis depends on manual inspection or lab analysis that cannot keep pace with an outbreak. We present AgriViTNet, a compact CNN-Vision Transformer hybrid built for exactly this constraint: It extracts local texture cues through convolution, relates them across the whole … …Journal of Computer Science, Vol. 22, Issue 9 · 20 Sep 2026 · 578 accessesView PDFCite
