transverse midline. The head of the capitate sits proximally into the space allowed by the lunate and scaphoid bones of the proximal carpal bone row. Proximally, the capitate has rounded surface whilst the distal end has a triangular shape with a palmarly directed apex. The dorsal, radial and ulnar surfaces are concave with…

object’s cross-sectional shape determines the form drag which is created by the pressure variation around the object and affects the induced drag of the lifting wing. The surface roughness of the object also affects the amount of drag. The material with smooth and waxed surface will produce less drag than a material with roughened surface. This skin friction effect is included in the measure…

Latent fingermark being imperceptible to the unaided eye is the decisive form of physical evidence found on divergent surfaces at the scene of crime. It is decisive because of its perpetuality and uniqueness. The word ‘fingerprint’ is common in commonality but individual to a person. When a person grasp something, he left the traces of residues (secretions of glands) conforming impression of the ridges of the fingers. The fingermark residue is a complex matrix of secretions and xeno-materials.…

technique are a few factors out of many that can cause injuries to athletes but one that is not talked about as much is playing surfaces. The idea that playing surfaces like artificial turf are harmful to athletes is a controversial topic because there are many critics that don’t believe that artificial turf can cause more injuries. However, it has been proven that artificial surfaces have flaws that cause injuries to athletes to increase. Factors like temperature, traction and impact reduction…

History of artificial turf Artificial turfs were developed as an alternative to natural grass surfaces in order to improve durability, decrease maintenance cost and, together with field lighting increase available playing hours. Additionally, artificial turfs are less impacted by weather conditions, resulting in an economically appealing choice for sports clubs and institutions, even with a higher initial investment compared to natural turf. (Reference Synthetic Turf and Lower Extremity…

the sample surface and the distance between the probe and sample is decreases. Probe is now coming towards sample and its now so close to the surface that is point B. Point C indicates that probe is in contact with sample surface and the piezo goes beyond that so that the probe deflected more. C-D indicates that the probe is in contact with surface and how sample starts deforming by the applied probe force. Region D-E shows that probe is being withdrawn from sample surface. Region…

Micropattern Named “ Sharklet ™ “ Transmission of bacterial infections, including MRSA and MSSA could be curbed by coating hospitals surfaces with microscopic bumps that mimic the scaly surface of shark skin, according to research published in the open access journal “Antimicrobial Resistance and Infections Control”. In other word the mimicking of the shark’s skin is useful to prevent from bacterial infections to spread in hospitals facilities . The study modelled how well different materials…

al. [2014] studied the effect of various cutting parameters in hard turning of AISI H13 steel at 55 HRC with Poly vapour deposit (PVD) coated TiCN ceramic tool under dry cutting conditions. They used Central composition design concept of Response surface methodology for design of experiments and concluded that abrasion was the principal wear mechanism observed…

that students would be able to identify which surface the cars moves easiest on and be able to explain why the car stops at different lengths on different surfaces. To start the lesson off, we did a vocabulary matching game to review the vocabulary words from the week before that the students needed to review for the rest of the lesson. The vocabulary words were speed, friction, and air resistance. Students were supplied with three different surfaces (carpet, aluminum foil, and sandpaper) and a…
