Diagnosis by Transbronchial Biopsy
blood gas levels showed hvpoxemia, with an increased alveolar arterial gradient (Table 1). Laboratory findings disclosed the following values: erythrocyte sedimentation rate (ESR), 20 mm/Is; hemoglobin level, 13.8 g/dl; leukocyte count, 8,200/mm3, with a normal differential cell count; platelet count, 397,000/mm3; BUN, 10 mgidl (normal range, 5 to 25 mg/dl); creatinine, 1 mg/dl (normal range, 0...
متن کاملEvaluation of Composite Vane Materials for Rotary Sliding Vane Compressors
The physical performance characteristics of composite materials used for vanes in rotary, sliding-vane compressors, in general, are several orders of magnitude more difficult to quantify for design purposes than most homogeneous materials. This arises from the numerous variables that influence the response of these materials under the severe environmental conditions existing in such compressors...
متن کاملVane Dynamics Analysis of a Tilted Vane Rotary Compressor
An analytical model of vane dynamics in a tilted vane rotary compressor is presented. With the geometric relationship of the vane in a tilted slot, and the roller, the kinetic equations were derived for evaluating the reciprocating inertial force of the vane, and the chamber volume equations were obtained for calculating pressure history inside the compression chamber. The empirical friction co...
متن کاملVane Behavior in Vane Compressors Under Start-up Operation
Vane oompressors can not maintain contact between a vane tip and a cylinder wall under start-up operation since backpressure acting on the vane is not sufficient. We theoretically analyzed transient behavior of the vane under the start-up operation by taking account of changes of the backpressure and discharge pressure after compression starting. The validity of the theoretical analysis was con...
متن کاملCore Biopsy as Alternative to Fine-Needle Aspiration Biopsy in Diagnosis of Breast Tumors.
In spite of the widespread use of cytological smears for diagnosis of breast cancer lesions, many surgeons are still reluctant to accept the cytological report as the only criterion for performing definitive surgery. Modern surgical strategy requires a preoperative planning of the surgical treatment, possible through the use of core biopsy, which provides a diagnosis based on tissue specimens, ...
