Research ArticleOpen accessIn the keywordsSelection of Kalmyk Cattle in KazakhstanAnuarbek Temirbekovich Bissembayev, Alzhan Smailuly Shamshidin, Zhanat Maratovich Kasenov et al.The purpose of the study is to determine the precocity of Kalmyk cattle breeding stock in Kazakhstan and the accuracy of productivity assessment by indices of breeding value. It is established that calves are born with a live weight of 22.4-25.7 kg, at the age of six months they reach a live weight of 165.2-175.3 kg. The average daily increase … …OnLine Journal of Biological Sciences, Vol. 24, Issue 1 · 23 Nov 2023 · 5,716 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEidonomy of Apis mellifera Workers and Drones in ApiariesAnuarbek Temirbekovich Bissembayev, Natalia Evgenievna Zemskova, Vener Nurullovich Sattarov et al.In modern ecosystems, the increasing anthropogenic load, the absence or an insufficient number of scientifically based integrated programs and measures for the reproduction and distribution of local bee populations, as well as the preservation of their habitat territories; unsystematic hybridization leads to the transformation of the quantitative and qualitative composition of bees in the regions. In connection with the presented … …OnLine Journal of Biological Sciences, Vol. 23, Issue 2 · 16 Mar 2023 · 5,110 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTHE ADVERSE EFFECT OF STEEL PARTICLE CONTAMINANTS ON FATIGUE LIFE OF GREASE LUBRICATED BALL BEARINGSA. Stathis, Th. Costopoulos, D. Koulocheris, K. RaptisThe rating life of ball bearings is reduced when hard particle contaminants are present in the lubricant. Usually, this life reduction is taken into account in the calculation of modified rating life by using the contamination factor through a general characterization of the lubrication conditions. However, the impact of contaminant’s variables such as size, hardness and concentration level has to … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 14 Jul 2014 · 6,991 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAirway Metrics, Anatomy and Growth Performance of Pigs Reared Indoors and OutdoorsChakia Joi McClendon, Sherrell Pettiford, Dawn Conklin et al.While the swine industry has made incredible strides to improve ventilation, air quality in confinement buildings remains an issue. The goal of this study is to characterize correlation between large airway metrics and growth performance in piglets reared indoors and outdoors on pasture. Three experimental trials were conducted: Trial 1 included three breed types that were strictly raised indoors, Tamworth … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 4 · 24 Sep 2013 · 7,582 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUncertainty and its Impact on the Quality of MeasurementMartin Halaj, Adel Elahdi M. YahyaThe imposition of practice, the current world, the laboratory measurement, calibration should be approved by points of credit to national or international and should be compatible with the requirements specification (ISO 17025) for the adoption of efficient laboratories. Those requirements were included the testing process or scale limits to doubt that mentioned in the measurement certificate, which recognizes the customer … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 4 Jul 2012 · 8,276 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExperimental Study of Load Sharing in Roller-Bearing Contact by Caustics and PhotoelasticityKonstandinos G. Raptis, George A. Papadopoulos, Theodore N. Costopoulos, Andonios D. TsolakisProblem statement: In this study a comprehensive methodology for calculating load sharing in Roller-bearing contact was presented based on the experimental stress-optical method of caustics and Photoelasticity. Approach: The theoretical equations describing the geometry of transmitted caustic in relation to the length of the contact zone were derived and a simple mathematical set of equations correlating the maximum diameter of … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,397 accessesView PDFCite
