Background: Coronary artery bypass surgery is one of the widely used treatment as every year more than 1 million coronary procedure are performed around world. The patients who have CABG prone to pulmonary complications. Pulmonary complications highly common after and incidence between 30% 60%. These most significant contributor morbidity, mortality expenses associated with hospitalization. Dev...

in this paper, based on equations of lateral vibrations of wires, a non contact method for measuring instantaneous tension in a wire is introduced. the lateral vibration of the string is measured using an eddy current transducer and is sent to a computer. this signal is then imported to suitable software for fast fourier transform (fft) processing. the first natural frequency of the string is c...

If an individual inspires as deeply as he can and then expires his whole vital capacity as rapidly as he is able into a recording spirometer the resulting record is known as a fast vital capacity (F.V.C.) tracing, or, sometimes, as an expiratory vital spirogram (E.V.S.). Recently much attention has been given to the possibility of using this record as a basis for the prediction of the maximum v...

Purpose – This paper attempts to review recent advances in wire bonding using copper wire. Design/methodology/approach – Dozens of journal and conference articles published recently are reviewed. Findings – The problems/challenges such as wire open and short tail defects, poor bondability for stitch/wedge bonds, oxidation of Cu wire, strainhardening effects, and stiff wire on weak support struc...

Current experimental investigation deals with the effects of asymmetrical rolling parameters on the inhomogeneity, microstructure, mechanical, and geometrical properties of rolled brass wire. Toward this end, a roll machine with three different roll radii ratios was set up. The asymmetrical conditions are arranged using three different sets of rolls with different diameters that result into dif...

We investigated whether professional athletes may require higher tidal volume (Tv ) during mechanical ventilation hypothesizing that they have significantly higher "normal" lung volumes compared to what was predicted and to nonathletes. Measured and predicted spirometric values were recorded in both athletes and nonathletes using a Spirovit SP-1 spirometer (Schiller, Switzerland). Normal Tv (6 ...
