Research ArticleOpen accessIn the abstractParticle Size Determination in Rice Bran Testing with Various Levels of Rice Husks Using Ultrasonic WavesUrip Rosani, Iman Hernaman, Rahmat Hidayat, Darmawan HidayatThe principle of ultrasonic waves in detecting materials is based on their physical properties. The size of particles has an impact on various aspects of their composition and function. The limited information that reports the particle size of RH-contaminated RB samples tested using ultrasonic waves is the basis for this study. This study aims to determine the optimal sample particle … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 6 Nov 2024 · 4,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Environment on the Morphometric Characteristics of Honeybees Apis Mellifera Carnica in South-East KazakhstanUlzhan Auezkhanovna Nuraliyeva, Nuradil Nurbekuly Spatay, Ainur Malikovna Davletova et al.Morphometric characteristics of honey bees (length and width of wings, number of roots) depend on the environmental conditions (in particular, the temperature regime) in which individuals develop. The purpose of the study is to determine the distribution of honey bees and a comparative analysis of their morphometric indicators in various climatic zones of South-Eastern Kazakhstan. The main climatic zones of … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 24 Sep 2023 · 5,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractWillingness to Pay for Wood Work Enterprises to Recover Deforested Softwood Trees in Eastern EthiopiaDaniel Habtamu Hailemichael, Lemma Zemedu, Jemma HajiThis study was carried out to find out the economic value of forests by woodwork enterprises for the reforestation of Softwood Pine trees in Eastern Ethiopia, namely Dire Dawa administrative council, Harari regional state, and Deder district of East Hararghe Zone. Forests in Eastern Ethiopia were the major sources of softwood pine logs. Nowadays, some commercially important pine species are … …American Journal of Agricultural and Biological Sciences, Vol. 18, Issue 1 · 16 May 2023 · 6,111 accessesView PDFCite

Research ArticleOpen accessIn the abstractLeaching of a Nigerian Refractory Gold Ore Using Aqua RegiaOluwasanmi Samuel Teniola, Abraham A. Adeleke, Simeon Ademola Ibitoye, Moshood Deinde ShituIn this research, refractory gold ore from Imogbara deposit in Iperindo area of Osun state Nigeria were collected systematically from various segments of the deposits at different depths to obtain a set of samples that truly represent the deposits. The 50 kg sample collected was subjected to panning in a flowing river to obtain about 1 kg-upgraded sample. The upgraded … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 1 · 13 Mar 2022 · 7,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating the Effect of Soil Particle Characterization on Internal Friction AngleArezou Rasti, Hamid Ranjkesh Adarmanabadi, Maria Pineda, Jesse ReinikainenOne of the critical design parameters used in evaluating soil structure is the friction angle, derived from Mohr's Circle failure criterion. The soil friction angle is an engineering parameter estimated in the laboratory to quantify the soil shear strength in geotechnical applications. This paper indicates an experimental study investigating the impact of particle size on different sandy soils shear strength … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 21 Feb 2021 · 8,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrincipal Component Analysis of the Female Pengging Soloan Duck Based on Morphometric TraitsRini Nur Hayati, Subiharta, Yudi Adinata et al.The Pengging Soloan duck is an emerging indigenous genetic resource from Central Java, Indonesia, recognized for its adaptability and egg-laying potential. However, its phenotypic characterization remains limited compared with established Indonesian duck breeds such as Mojosari, Tegal, and Magelang ducks. This study aimed to characterize 70 adult female Pengging Soloan ducks aged 5 6.5 months using Principal Component Analysis (PCA) … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 10 Sep 2026 · 940 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnxiety-Focused Classification Using Smartphone-Based Gait Analysis and Deep Learning ModelsMinchan Kang, Gou-Sung Degbey, Hyunhwa Lee et al.Mood disorders, such as anxiety, significantly impact individual well-being and present challenges to healthcare systems globally. Traditional screening methods, including self-administered symptom questionnaires, provide valuable insights into symptoms but may miss dynamic fluctuations. This study explores the potential of smartphone inertial sensors and deep learning models for anxiety risk classification. Using gait data from 36 participants, collected via smartphone accelerometers … …Journal of Computer Science, Vol. 22, Issue 7 · 16 Jul 2026 · 821 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Probit and Logistic Regression Models in the Analysis of Dichotomous OutcomesAmrutha Jose, Mariyamma Philip, Lavanya Tumkur Prasanna, M. ManjulaProbit and logistic regression models are members of the family of generalized linear models, used for estimating the functional relationship between the dichotomous dependent and independent variables. The current study is designed to find the performance of logistic and probit regression models in different conditions under multivariate normality. The objective of the study is to compare the performance of probit … …Current Research in Biostatistics, Vol. 10, Issue 1 · 26 Mar 2020 · 17,036 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing a Hierarchical Weibull model to Predict Failure Strength of Different Glass Edge ProfilesDavid Thomas Kinsella, Johan LindströmThe edge strength of glass is analyzed using a Weibull statistical framework based on 78 data samples from a range of experiments recorded in literature. Based on the analysis, a 45 MPa strength value (computed as the lower bound in a one-sided confidence interval at the 75% level for the 5-percentile in the distribution) could be conservatively used with arrised, … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 30 Apr 2020 · 8,274 accessesView PDFCite
