Research ArticleOpen accessPhrase in the titleParticle 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 accessPhrase in the titleThe Application of Numerical Taxonomy Technique in the Iron Ore Flotation to Determine Appropriate pH and Particle Size DistributionRasoul Khosravi, Fahimeh Dehghani, Hossein Siavoshi et al.The numerical taxonomic technique is one of the multivariate decision-making techniques for assessment and ranking. It is widely used for planning and development studies. In this research, flotation experiments were conducted for Band Narges mine iron ore using different pH and particle size ranges. Numerical taxonomy technique, as one of the most important multi-attribute decision-making techniques, was used to determine … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 24 Dec 2020 · 6,695 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleThe Association between Total Mixed Ration Particle Size and Fecal Scores in Holstein Lactating Dairy Cows from Florida, USAPedro Melendez, Elizabeth RoyThe objective of this study was to determine the association between the proportion of particles greater than 19 mm in a total mixed ration fed to dairy cattle and their fecal score. Over a 22 day period, random feed samples were collected twice a day from a one-side barn and assessed for particle size using the Pennsylvania State Particle Separator. … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 6 Jan 2016 · 8,084 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEvaluation of Aerosol Particle Size at High Polluted Region in the World Using Direct Solar Radiation Measurements: Helwan as a Case RegionU. Ali RahomaProblem statement: Particle counting and sizing of atmospheric aerosols by electro-optical methods are complex and absolute interpretation of measurements is difficult, so, the scattered light varies in a complicated manner with the system of optics as well as with the size and physical characteristics of particles. Approach: The estimation of the air aerosol number concentration variation was carried out in … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 8 May 2010 · 6,670 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleRepresentative Particle Size of Sediment in Storm Sewer InletsJaber Almedeij, Ebtehal Ahmad, Jasem AlhumoudProblem statement: The aim of this study was examine the representative particle size of noncohesive sediment samples collected from different storm sewer inlets in residential catchments within Kuwait. Approach: A number of 25 sediment samples were collected from storm sewer inlets located in five residential areas in Kuwait: Bayan, Al-Nuzha, Al-Feiha, Al-Andalos and Al-Rumaithya. All the impervious areas for the … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,194 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleThe Effect of Milling Time on Ni0.5Zn0.5Fe2O4 Compositional Evolution and Particle Size DistributionI. Ismayadi, M. Hashim, A. M. Khamirul, R. AliasProblem statement: This study involved an investigation to ascertain the diffusion of NiO and ZnO into the tetrahedral and octahedral sites using mechanical alloying method. The effect of mechanical alloying towards particle size was also reported. Approach: NiO, ZnO and Fe2O3 precursors were mechanically alloyed to synthesis ultrafine powders of Ni0.5Zn0.5Fe2O4. Various milling times were employed to study the effect … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,998 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePresenting a New Equation that Accurately Determines the Size of a Moving Elementary ParticleFlorian Ion Tiberiu PetrescuThe paper briefly presents a new Eq. (9). The role of Eq. (9) is to accurately determine the size of a moving elementary particle, depending on its velocity (or particle energy). Although Eq. (9) has a general character, it can be applied to any elementary particle in motion to determine the size of that particle, in the study, it was … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 24 Nov 2022 · 6,475 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGrain Size Distribution Characteristics Variation in Oily Contaminated Sandy Soils Due to Long Term Aging Effect in Al-Ahmadi Field at KuwaitHumoud Melfi Aldaihani, Fahad A. Alotaibi, Farraj F. Al-ajmiAlmost three decades on, the negative environmental impacts arising from the burning of over 600 oil wells in Kuwait following the 1991 Gulf War are still evident. At the time of the incident, the Kuwaiti desert region became polluted with hydrocarbon, with a number of ‘oil lakes’ forming, causing critical harm to local land. This paper discusses the shifts in … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 23 Nov 2018 · 8,409 accessesView PDFCite
