Research ArticleOpen accessIn the abstractPresentation of a Mechanism with a Maltese Cross (Geneva Driver)Florian Ion Tiberiu Petrescu, Taher M. Abu-Lebdeh, Antonio ApicellaThe paper presents briefly a mechanism with a cross of Malta. The mechanisms with a Maltese cross (Geneva driver) are present in automation, robotics, mechanical transmissions, continuous variable transmissions, old clocks, especially when it comes to transmitting forces and high moments, being used instead of or with the gears. The geometry of the mechanism consisting of two elements, the kinematics … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 8,549 accessesView PDFCite

Research ArticleOpen accessIn the abstractThe Rise of the Physical Sciences in “Stricto Sensu” The Developmental Approach and the History of SciencesGeorg W. OesterdiekhoffJ. Piaget dedicated several books and articles on the psychogenetic reconstruction of the history of sciences. A couple of disciples followed Piaget´s ideas and reconstructed the history of single disciplines or of some scientific developments in terms of developmental psychology. They found a striking similarity between childish psychological stages and the sciences in their premodern period. Correspondingly, they also found … …Physics International, Vol. 8, Issue 1 · 31 Oct 2017 · 8,636 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Dynamic Model for GearsAversa Raffaella, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuNearly all models studying the dynamic of gearing with parallel axes are based on classical mechanical models and known which are studying the spinning vibration of shafts gears and determine their own beats and strains of shafts spinning. These classical dynamic models are very useful, but they didn't take in consideration the dynamic events formed between the two teeth in … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 10 May 2017 · 7,644 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Playing Surface and Shoe Type on ACL Tears in Soccer PlayersMelissa M. Mansfield, Ronald B. BucinellToday, Anterior Cruciate Ligament (ACL) tears are one of the most prevalent knee injuries, with the occurrence of ACL tears increasing drastically from approximately 80 000 in 2000 to 150 000 in 2011. Although there are many factors that contribute to an ACL tear occurring, certain environmental factors could contribute to the dramatic increase over the past couple decades, especially … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 15 Dec 2016 · 12,888 accessesView PDFCite
Review ArticleOpen accessIn the abstractRecent Advances in Point of Care Diagnostic Tools: A ReviewLaura Wessels, Haider RaadGlobally, there is a great need for portable, inexpensive diagnostic tools that can provide quick, accurate results using relatively small sample volumes. Point-Of-Care (POC) measurements of human saliva, sweat and/or blood capable of detecting glucose levels, foreign pathogens such as bacteria, fungi and many different viruses (HIV, Ebola, Influenza, etc.) that use microfluidics and optofluidics are close to commercial availability. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 28 Nov 2016 · 8,234 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Immunomagnetic Separation Method for Viable Salmonella Typhimurium Detected by Flow CytometryShakil Ahmed, Horst-Günter Rubahn, Helmut ErdmannA very small number of bacterial pathogens may have fatal effects on food safety. In spite of having great advancements in bioanalytical methods, most of the accepted detection methods are still cultivation based and thus time consuming. This leads to an intense need for efficient and rapid methods for detection of food-related bacteria. In this study, a flow cytometry based … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 25 Nov 2016 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Content of Heavy Metal in the Labu Riverbed Sediments: An Assessment of the Level of Pollution Applying Sediment Quality Guidelines and Geoaccumulation IndexAhmad Shoaib Jahesh, Sahibin Abd Rahim, Wan Mohd Razli IdrisRiver bed sediments from thirteen (13) sampling stations, from Labu River were collected in June and December 2014. The aim is to identify the source and ascertain the current levels of heavy metal pollutions. The selected heavy metals (Cr, Cu, Fe, Ni, Zn, As, Cd and Pb) were analysed by using Inductively Couple Plasma Mass Spectrophotometry (ICPMS). Metals were statistically … …American Journal of Environmental Sciences, Vol. 12, Issue 4 · 10 Aug 2016 · 7,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simple Model of Gauged Lepton and Baryon ChargesP.V. Dong, H.N. LongWe propose a simple extension of the standard model with lepton and baryon numbers gauged by introducing only two leptoquarks (j+1/2, k-1/2) to the fermion content. As natural consequences of the anomaly cancelation, the right-handed neutrinos present and the number of observed fermion families equals to the number of fundamental colors, which is three. To avoid stabilized colored-leptoquarks, two scalar … …Physics International, Vol. 6, Issue 1 · 20 Jun 2015 · 7,878 accessesView PDFCite
