Flexible and Slim Device Switching Air Blowing and Suction by a Single Airflow Control

Tonsillar gonorrhoea demonstrated by a suction device.

Gonorrhoea of the oral cavity has been demonstrated with increasing frequency in recent years among heterosexuals as well as homosexuals (Schmidt, Hjorting-flansen, and Philipsen, 1961; Cowan, 1969; Bro-Jorgensen and Jensen, 1971; Hellgren, 1971; Owen and Hill, 1972; Ratnatunga, 1972; Rodin, Monteiro and Scrimgeour, 1972; Odegaard and Gundersen, 1973; Wiesner, Tronca, Bonin, Pedersen, and Holme...

Development of an Ultrasonic Airflow Measurement Device for Ducted Air

In this study, an in-duct ultrasonic airflow measurement device has been designed, developed and tested. The airflow measurement results for a small range of airflow velocities and temperatures show that the accuracy was better than 3.5% root mean square (RMS) when it was tested within a round or square duct compared to the in-line Venturi tube airflow meter used for reference. This proof of co...

Hypoxia caused by a faulty Steri-cath closed suction device and use of continuous suction.

Numerical Study of Blowing and Suction Control Mechanism on NACA0012 Airfoil

A jet with a width of 2.5% the chord length is placed on a NACA0012 airfoil’s upper surface simulating the blowing and suction control under Re = 5 × 105 and angle-of-attack 18-deg conditions. Nearly 300 numerical simulations are conducted over a range of parameters (jet location, amplitude, and angle). The physical mechanisms that govern suction and blowing flow control are determined and anal...

‏‎a comparative study of language learning strategies employmed by bilinguals and monolinguals with reference to attitudes and motivation‎‏

هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
