Presents article is deal with optimization of the fixture for end milling process, the most important objective being the minimization of work piece deformation by changing the layout of fixture elements and the clamping forces. The main objective of this work has been the optimization of the fixtures Work piece deformation subjected to clamping forces for End milling operation. The present ana...

RATIONALE Milling of wood samples is a widely applied preparation method for pooling tree-rings from different trees or periods of several years for determination of δ(13)C and δ(18)O values. In this study, whole wood samples were milled using different procedures in order to evaluate potential effects of this preparation method on δ(13)C and δ(18)O values. METHODS Subsamples of a 5 cm(3) woo...

BACKGROUND We compared the efficacy of and consistency in manual ventilation by trained healthcare professionals using three devices: self-inflating bag, flow-inflating bag, and T-piece resuscitator. METHODS Prospective analytical study at a level III Neonatal unit of a tertiary care hospital. Forty participants (consultants, postgraduates, interns, and neonatal nurses - 10 each) manually ven...

People use trains as a means of transportation to travel various nearby and distant destinations, resulting in an increasing amount time spent inside such vehicles. Consequently, railway sectors are focusing significantly more on enhancing passengers’ demand level satisfaction, including but not limited high-speed travel, safety, riding comfort. This paper provides state-of-the-art review avail...
