To improve our understanding of Helicobacter  infection in cats and to determine whether they are reservoirs for H. pylori  and sources of zoonotic transmission to humans, we selected cats as an experimental animal model for gastric colonization by H. pylori. Sixteen stray cats underwent Helicobacter  eradication treatment followed by three consecutive oral inoculations of a cocktail of human H...

in the business environment, virtual organizations can meet market needs efficiently and effectively via knowledge worker and high flexibility and also generate significant competitive advantage. due to obtaining the advantage of these organizations, managerial issues related to them must be recognized and organized. decrease of face to face relationship, geographically distributed, dynamic job...

This paper deals with kinematics and dynamics of the human shoulder in order to obtain the workspace related to the reachability of the wrist and applications to determine load for the wheelchair. The model contains six revolute degrees of freedom (D.O.F), two in costoclavicular and three in the shoulder joint and one in the elbow joint, while a six D.O.F model was developed according to given ...

Realistic geometry of human upper airways from mouth to the end of trachea was reconstructed by implementing the CT-Scan images of a male subject.   A computational model for analyzing the airflow in the airways was developed and several simulations were performed.  To capture the anisotropy of the inhaled airflow in the upper airways, the Reynolds stress transport model of turbulence was used ...
