Ameloglyphics is the study of enamel rod end patterns on a tooth surface. Our aim was to study the in vivo analysis of enamel rod end patterns on tooth surfaces for personal identification. In this study, the maxillary left canine and 1st premolar of 30 men and 30 women were included. The cellulose acetate peel technique was used to record enamel rod endings on tooth surfaces. Photomicrographs ...

In reciprocating engines, connecting rod cap and bolts are critical as they exposed to varying loads under different operating conditions. This paper focused on the failure of a 1.5 dci K9K diesel engine. As result engine for approximately 378400 km, was broken, reasons bolt were investigated. The designed in accordance with dimensions SolidWorks software then exported ANSYS stress fatigue anal...

Kinesin, a protein that transports particles along microtubules, has been purified from pig brain, following published methods. By electron microscopy of both shadowed and negatively stained specimens, it appears to be a rod with a large branched structure at one end and a small fork at the other. The total length of the structure is about 100 nm. The rod has a diameter of 2-4 nm. Close to the ...

In this experiment, κ, the thermal conductivity of a rod of brass, was measured by periodically heating one end of the rod. Turning the heater attached to the rod on and off with a 10 mHz square wave signal, waves of heat were sent along the length of the rod, measured by two thermistors a distance ∆x apart. Taking these temperatures as a function of time, a Fourier transform was applied to a 1...

DNA is thought to behave as a stiff elastic rod with respect to the ubiquitous mechanical deformations inherent to its biology. To test this model at short DNA lengths, we measured the mean and variance of end-to-end length for a series of DNA double helices in solution, using small-angle x-ray scattering interference between gold nanocrystal labels. In the absence of applied tension, DNA is at...
