Alternative implementations of a Rear Cross Traffic Alert (RCTA) system intended to actively notify drivers of the presence of rear cross-path traffic when backing were evaluated in naturalistic settings. The feature is one of several emerging technologies designed to assist drivers when backing in this case, enhancing drivers' awareness of traffic approaching from the rear. The study allowed p...

It’s been known for many years that thermal temperature gradients across a rotor can alter the amplitude and phase of synchronous vibration. This is due to bowing of the shaft caused by a temperature difference between one side of the shaft and the other. The earliest published recognition of this phenomenon was by Newkirk [1], where the temperature difference was a result of frictional heating...

In order to have fault identification for the gate rotor shaft with multiple cracks effectively, the quantity identification method of the gate rotor shaft with multiple cracks based on wavelet finite element method is established and the frequency test of the gate rotor shaft based on blind source separation algorithm is analyzed. Firstly the wavelet finite element was established by combining...

Analysis of genotypes for genetic predisposition of diseases has profound and widespread clinical application and has become a fundamental tool in the study of molecular epidemiology. In this study, we report a convenient and completely noninvasive approach to perform genotyping using terminal cephalic hair shaft. The average and median DNA amounts purified from the hair shaft are 112 +/- 180 (...

The fiber shaft of human adenoviruses (HAdVs) is essential for bringing the penton base into proximity to the secondary cellular receptor. Fiber shaft sequences of all 53 HAdV types were studied. Phylogeny of the fiber shaft revealed clustering corresponding to the HAdV species concept. An intraspecies recombination hot spot was found at the shaft/knob boundary, a highly conserved sequence stre...

Signal variation caused by motions along the lift shaft in a campus environment and on board a ship is compared. The guiding effect is common for both lift shafts, and the variation in amplitude of the guided signals is more significant for the lift shaft with larger dimensions. Unlike the lift shaft within the campus, the ship with its lift shaft forms a ‘waveguide within waveguide’ structure....

Monilethrix or beaded results from a genetic abnormality of defective hair shaft formation. The altered genetics leads to improper, inefficient, incorporation of structural proteins, minerals during hair shaft formation resulting in weak, brittle hair. Other hair shaft disorders like pili torti, pili trianguli, trichorrhexis nodosa, trichorrhexis invaginata and pili annulati, rolled hair and ci...

Treatment of Displaced diaphyseal femoral shaft fracture in children between 3 to 13 years is controversial. Various methods are available for treatment. Titanium elastic nailing is one of the methods for treatment of femur shaft fracture in children. In our study we have assessed the outcome of titanium elastic nailing for fracture shaft femur in children. We have found that titanium elastic n...
