Forty male … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 28 Apr 2021 · 6,663 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordStructural Dynamics of the Distribution Mechanism with Rocking Tappet with RollFlorian Ion T. Petrescu, John Kaiser Calautit, Dragan MarinkovicIn this study, the authors present a new method to dynamically synthesize a mechanism with rotary cam and rotated tappet with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. This type of distribution can improve the changes of gases and may decrease significantly the level of vibration, noises and emissions. As long as … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 28 Oct 2015 · 9,290 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordStructural and Dielectrical Properties of Sterilized Human TeethMostafa Fawzy Eissa, Hassan Mohamed El-Shamy, Hassan Saad HanafyProblem statement: This study investigated the changes in crystallinity and dielectrical properties (conductivity) that could be demonstrated in extracted human teeth (enamel and dentin) subjected to γ-radiation at the sterilization dose (25 kGy). Approach: Twenty human third molar teeth were used in the study. Teeth were prepared so forty enamel and dentin samples were obtained. The samples were divided into … …Physics International, Vol. 3, Issue 1 · 20 Dec 2012 · 7,182 accessesView PDF Cite
