Most institutions performing cardiopulmonary bypass for congenital heart disease patients use an integrated hard shell cardiotomy and venous reservoir attached to an oxygenator. It is of paramount importance that the integrated reservoir be vented so as not to cause pressurization. A pressurized sealed cardiotomy has been reported to occur secondary to issues with vacuum assisted venous drainag...
Twelve adult asthmatic patients participated in an open, randomized, cross-over comparison between cumulatively increasing doses of terbutaline sulphate administered via the multiple dose powder inhaler (Turbuhaler) or via a pressurized inhaler. Turbuhaler and the pressurized inhaler showed equipotency both with respect to bronchodilatation and side effects. Both treatments produced a significa...
We present the case of a 22-year-old man who sustained a gunshot wound to the scrotum. The imaging findings and management of the patient are described and discussed in the context of prior research pertaining to traumatic bladder rupture. Non-pressurized antegrade 10-minute delayed CT may result in unnecessary radiation exposure, delayed diagnosis and is not adequate to exclude bladder rupture...
Crop protection is mostly carried out spraying active chemical agents with potential impact on the health of environment, operator and consumer. Recently the European Commission played an important role in the protection of the operator with respect to the pesticide contamination during spray application. An active protection offered by tractor cab is a new requirement when the machine is used ...
Injection of biomass powders into multiphase reactors is a challenging task that may impact the process yield and limit operation due to feeder’s blockage or unstable flow. A horizontal pressurized gas-solid feeder characterized in this study inject batch different diameters cold-flow model operating under single phase, fixed fluidized regimes. The hydrodynamics injection line investigated for ...
A Korean fusion energy development promotion law (FEDPL) was enacted in 2007. As a following step, a conceptual design study for a steady-state Korean fusion demonstration reactor (K-DEMO) was initiated in 2012. After the thorough 0D system analysis, the parameters of the main machine characterized by the major and minor radii of 6.8 and 2.1 m, respectively, were chosen for further study. The a...
Many different types of surface mining equipment use enclosed cabs to protect equipment operators from health and safety hazards. The overburden removal and mining process can be extremely dusty and can cause excessive dust exposure. To study this issue, a cooperative research effort was established between the National Institute for Occupational Safety and Health, U.S. Silica Co., Clean Air Fi...
It is well known that safety in the operation of nuclear power plants a primary requirement because failure this system can result serious problems to environment. A reactor has several systems help keep it normal operation, within margins. Many these operate control variable quantities circuit reactor. However, reactors are nonlinear physical systems, and introduces complexity strategies. Amon...
