The Indonesian Ocean Energy Association has ratified the potential for ocean wave energy in Indonesia with a theoretical of 141,472 Megawatts. Unfortunately, this vast not yet been utilized optimally seas. technology developed rapidly various countries worldwide. One most famous power generation technologies is Oscillating Water Column (OWC), which utilizes airflow from waves oscillating moveme...

OBJECTIVES The purpose of this study was to determine whether the dynamic cause for mitral systolic anterior motion (SAM) is a Venturi or a flow drag (pushing) mechanism. BACKGROUND In obstructive hypertrophic cardiomyopathy (HCM), if SAM were caused by the Venturi mechanism, high flow velocity in the left ventricular outflow tract (LVOT) should be found at the time of SAM onset. However, if ...

BACKGROUND The OxyMask (Southmedic Inc, Canada) is a new face mask for oxygen delivery that uses a small 'diffuser' to concentrate and direct oxygen toward the mouth and nose. The authors hypothesized that this unique design would enable the OxyMask to deliver oxygen more efficiently than a Venturi mask (Hudson RCI, USA) in patients with chronic hypoxemia. METHODS Oxygen-dependent patients wi...

Venturi-assisted ENTrainment and Ionization (VENTI) was developed, demonstrating efficient entrainment, collection, and transport of remotely sampled vapors, aerosols, and dust particulate for real-time mass spectrometry (MS) detection. Integrating the Venturi and Coandă effects at multiple locations generated flow and analyte transport from non-proximate locations and more importantly enhanced...

Offshore wind turbine is now being seriously considered as a crucial energy source to achieve not only CO2 reduction, but also to meet the enormous power shortages that occur in India and around the world. Nevertheless offshore wind energy is not competitive as on today with other sources of energy. There are combination of some select technologies which could bring about improvement in offshor...

We evaluated four commercial transport systems with a standardized inoculum of clinical isolates of N. gonorrhoeae (NG), and assessed survival after holding for up to 48 hours at both ambient and refrigeration temperatures. Suspensions of clinical isolates of NG were standardized and adsorbed onto four transport swab types: Culturette EZ (Becton Dickinson [BD], Cockeysville, MD, USA); Culturesw...

Air induction nozzle (AIN) has a special Venturi structure that been widely used in the field of reducing probability drift pesticide droplets and realizing precise application. The present research mainly adopts method comparative test analyzes difference between AIN standard fan nozzle. However, on internal flow characteristics air–liquid ratio (ALR) is very limited. In order to detect air-li...

The gas–solid flow of mixed seeds oat and vetch in the air-blowing venturi tube was simulated numerically by means a coupling approach discrete element method (DEM) computational fluid dynamics (CFD). In model, EDEM software used to depict particle phase, ANSYS Fluent describe continuous gas phase. effects seed entry angle inlet air velocity on uniformity supply were studied analyzed from airfl...

Thermal nuclear reactor power is typically evaluated with secondary system calorimetric calculations based on feedwater flow rate measurements. The feedwater flow rate should therefore be measured accurately. Venturi meters are currently used to measure the feedwater flow rate in most pressurized water reactors (PWRs). The long-term operation of a nuclear power plant causes a buildup of corrosi...
