Gradual increase of the Earth's surface temperature can cause many significant changes on the climate of our planet. This problem is progressively increasing. One of the main reasons for this phenomenon is the absorption of the Sun's energy and lack of proper reflection of emissions due to man-made activities, one of which is the increase in black surfaces. In this descriptive and cross-sectio...

a practical application of the spherical involute surface to the forged straight bevel gears is provided and demonstrated in this work. conjugate (pure involute) theoretical surfaces are developed from the input design parameters. the surfaces are modified to suit the actual application (automotive differential). the unloaded (or low load) tooth contact analysis of modified surfaces is performe...

Ice accretion on surfaces is a major economic concern in the energy and transportation industries, particularly due to need of frequent maintenance. In contrast traditional de-icing approaches involving use electrical, mechanical, chemical or combinatorial approach, icephobic inspired by nature more environmentally friendlier solution. Understanding fundamentals interaction liquid with solid at...

relative diffuse reflection measurements from the original and ground surfaces using a he-ne laser are reported. the intensity measurements for the metallic, transparent dielectric, matte plastic surfaces and colored papers are presented. our results indicate that among metallic surfaces tested, aluminum has the highest diffuse reflectance; while the original stainless steel surface shows the l...

Background and Aim: The present study introduces photofunctionalization as a technique for tackling biological aging and increasing the bioactivity of titanium. This in-vitro study evaluated the effects of ultraviolet (UVC) light treatment of titanium surfaces with different time-related changes on the behavior and function of human mesenchymal stem cells (MSCs). Materials and Methods: MSCs we...
