a-56-year-old woman underwent carpal tunnel release surgery under general anesthesia. thirty minutes after extubation, the patient complained of chest discomfort with dyspnea. swelling of the neck and upper anterior chest was observed. computed tomography of the chest showed tracheal rupture at the brachiocephalic trunk level, and bronchoscopy demonstrated a 5 cm linear tracheal defect in the p...

Numbers of fecal and vomit spots deposited by house flies, Musca domestica L., on spot cards were about twice as high on cards placed on the downwind sides as on the upwind sides of building support posts in caged-layer poultry houses with tunnel ventilation in Brooksville, FL. This trend was stronger at the ends of the houses where airflow is faster than in the relatively still-air center of t...

The data presented in this article were the basis for the study reported in the research articles entitled "Evaluation of a two-sided windcatcher integrated with wing wall (as a new design) and comparison with a conventional windcatcher" (P. Nejat, J.K. Calautit, M.Z.A. Majid, B.R. Hughes, I. Zeynali, F. Jomehzadeh, 2016) [1] which presents the effect of wing wall on the air flow distribution u...

The opencut tunnel is a kind of linear arch construction and new sand-prevention structure. In order to clarify the wind-proof mechanism tunnel, this paper seeks answer question whether Lin–Ce railway will be buried. paper, wind experiment combined with field investigation testing used systematically study sand resistance in an it verified burial possible. results show that airflow greater than...

By sealing the portal at one end of tunnel and changing transverse location linear fire source in tunnel, hot smoke layer, longitudinal temperature distribution maximum were investigated. It is found that flame will bend under influence curved ceiling layer be thicker when approaches to side wall. The variation law heat release rate analyzed by considering limiting effect wall thermal feedback....

• Door opening scenarios for a metro train fire were studied. A theoretical model the inner carriage smoke propagation was developed. Experiments conducted control of fire. Critical velocities and confinement two door proposed. The critical velocity, velocity back-layering length are significant factors in tunnel This research aims to analysis correlation these 3 key parameters different during...

Use of renewable energy resources might be the solution for electric power shortage in agricultural production. Wind turbines used places with higher wind potential, such as coastline Marmara Sea and Tekirdağ Province. Generally, natural ventilation greenhouses is insufficient. Mechanical must order to improve achieve desired levels. However, are generally located on rural areas mechanical cann...

In railway tunnels, ventilation is carried out to prevent NO, NO2, and CO gas pollution caused by exhaust gases due the diesel locomotives on railway. Some calculations are used during ventilation. these calculations, factors like location structure of tunnel pressure belts that may occur should be considered one one. After control scenarios prepared based locations dimensions equipment used. P...
