The present project involved a collective effort agreed by the European Society of Thoracic Surgeons, the American Association for Thoracic Surgery, the Society of Thoracic Surgeons, and the General Thoracic Surgery Club to assemble a joint panel of experts to review the available data and address ambiguous aspects of chest tube definitions and nomenclature. The task force was composed of 11 in...

Abstract The Richards’ equation describes the flow phenomenon in unsaturated porous media and is essential to hydrology environmental science. This study evaluated numerical stability of two different forms equation. Sensitivity analyses were performed investigate control parameters results show that h -form has better applicability for calculating variable saturation flows than θ For equation,...

We have developed the scroll co•pressor with variable capacity control nechanis•. The a•ount of bypassed gas fro• the co•pression chanber to the suction cha•ber is controlled by displace•ent of the bypass piston. This paper presents as follows. The analytical technique for calculatins perfor•ance of the co•pressor with by~pass-type capacity control •echanis• has been developed. Also, experi•ent...

Variable-speed centrifugal compressors are used in a wide variety of industries and applications, including natural gas pipelines and processing plants, oil refineries and chemical plants, air-separation units, refrigeration and air conditioning equipment refrigerant cycles, gas turbines and auxiliary power generators, and many more. Some natural gas plants, for example, employ a propane-precoo...

INTRODUCTION We compared the efficacy of Karl Storz CMAC Tip™ with inline suction to CMAC with traditional suction device in cadaveric models simulating difficult airways, using media mimicking pulmonary edema and vomit. METHODS This was a prospective, cohort study in which we invited emergency medicine faculty and residents to participate. Each participant intubated 2 cadavers (one with simu...

BACKGROUND Three kinds of conditions should be considered to reduce free hemoglobin production using an autologous cell salvage device. They are the negative suction pressure, the size of suction tip, and the air contact during suction. We want to examine which condition is the most important factor to produce free hemoglobin. METHODS One pack of red blood cell and one pack of fresh frozen pl...

Leaking in water pipe is a critical issue in Middle Eastern countries such as Kuwait where water is scarce. In-pipe robots can be dispatched to discover the network and inspect the inner surface of the pipe. This thesis describes the design and characterization of suction pads for in-pipe robots. The suction cups are made of hyperelastic materials that contain air channels inside. Instead of us...

PURPOSE To evaluate refractive outcomes of two management approaches after suction loss during the small-incision lenticule extraction (SMILE) technique. PATIENTS AND METHODS This retrospective and comparative study was conducted at the El-Gowhara Private Eye Center. It included 26 consecutive eyes of patients who experienced suction loss during the SMILE technique. Patients were divided into...
