A Simple Gravimetric Method to Determine Barometer Corrections
Presented here is a gravimetric me thod to calibr a te barometers. The difference in forces exerted on th e pan of a balance is observed for tw o we ll charac terized artifac ts of nearly equ al masses but different volumes. During the weighing, air tempera ture and re lative humidity ar e meas ured; the ambient pressur e is then calculated from an a ir density equation. A barometer correc tion...
متن کاملA Simple Method for Filling Ampoules
Wright (1912) described a method for filling ampoules based on the principle of first exhausting the air from the ampoules and then filling by atmospheric pressure. Since then many elaborate pieces of apparatus have been devised based on the same principle, but these are^ all expensive and not readily obtainable. The ^odification described below has the advantage that the apparatus required may...
متن کاملDiastolic function: a barometer for cardiovascular risk?
PERIOPERATIVE cardiovascular risk assessment has undergone significant advances, including development and validation of multivariable risk indices for prediction of major cardiac complications, advances in detecting ischemic heart disease, and noninvasive detection of symptomatic reductions in left ventricular (LV) ejection fraction. However, we have recently recognized that current preoperati...
متن کاملEndothelial function: a barometer for cardiovascular risk?
The endothelium regulates vascular homeostasis by elaborating a variety of paracrine factors that act locally in the blood vessel wall and lumen.1 Under normal conditions, the sum total effect of these endothelial factors is to maintain normal vascular tone, blood fluidity, and limit vascular inflammation and smooth muscle cell proliferation. However, when coronary risk factors are present, the...
متن کاملMethod for removing hypopharyngeal salivary bypass tubes.
OBJECTIVE To describe a novel method for the removal of the salivary bypass tube (SBT) that precludes the need for extraction under general anesthesia. STUDY DESIGN Retrospective case series. METHODS/TECHNIQUE Patients who had undergone laryngectomy/laryngopharyngectomy with subsequent development of pharyngocutaneous fistula and intraoperative placement of a salivary bypass tube were inclu...
