Trace metal contamination of evacuated blood collection tubes
American Industrial Hygiene Association Journal, 1977A study was undertaken to investigate the magnitude of potential trace metal contamination contributed by various commercial evacuated blood tubes to blood samples under experimental conditions. None of the tubes tested contributed significant Cu contamination whereas the 1% nitric acid and human blood leaching data clearly indicate that Zn, Pb and Cd ...

Comparative Study of Different Tube Geometries of Evacuated Tube Solar Collector
Journal of Solar Energy Engineering, 2023Abstract This study investigates the thermal performance of an evacuated U-tube solar collector (ETSC) using different tube geometrical configurations. The effect of tube geometry on the overall collector efficiency is numerically analyzed and compared with experimental results.

Numerical Simulation of Evacuated Tube Solar Water Heaters
Volume 6: Oil and Gas Applications; Concentrating Solar Power Plants; Steam Turbines; Wind Energy, 2012This paper evaluates the characteristics of water-in-glass evacuated tube solar water heaters including assessment of the circulation rate through single ended tubes. A numerical model of the fluid flow inside a single ended evacuated tube has been developed assuming no interaction between adjacent tubes in the collector array.

Effectiveness of chest tube evacuation ofpneumothorax in neonates
The Journal of Pediatrics, 1981This is a retrospective review of the effectiveness of 149 chest tubes placed in attempts to evacuate 91 pneumothoraces among 57 infants. Forty-four percent of initial evacuation attempts were ineffective; 42% of total chest tubes throughout the clinical courses were ineffective.

Natural Mode Solar Evacuated Tubes Desalination
2019Solar desalination using solar still is the simplest method to produce clean distilled water but it yield low potable water. Hence, evacuated tube solar distiller is used in this study and modified with triangle shape glazing. Waste water from restaurant in Ipoh, Perak Malaysia was collected for distillation process for duration of 1 month. The average

Tube sigmoidostomy: A modification of the antegrade colonic evacuation
ANZ Journal of Surgery, 2002Background: The Malone appendicostomy enema has established its place in the treatment of paediatric faecal incontinence. More recently, the laparoscopic appendicostomy enema has gained favour. In the situation where the appendix has already been removed, caecal stomal tubes can be constructed to facilitate antegrade colonic wash‐outs.

Wide aperture valve for evacuating shock tubes
Journal of Scientific Instruments, 1964Rapid evacuation of a shock tube has been achieved by pumping through an aperture formed by removal of a portion of the tube that is later replaced and aligned. A mechanism is described for this purpose.

Solar Energy Collection With Evacuated Tubes
Journal of Engineering for Power, 1965Engineering and economic considerations are given for nontracking solar energy collectors where the absorbing surface is insulated by an evacuated space. Each collector is a long glass tube, about two in. in dia, silvered in the lower portion. The selectively blackened conduit through which liquid flows is suspended within the evacuated tube, passing ...

Performance of Evacuated Blood Collection Tubes at High Altitude
High Altitude Medicine & Biology, 2008Researchers and clinicians may not be aware that the performance of evacuated blood collection systems is impaired at high altitude. We tested four sizes of Vacutainer tubes at altitudes ranging from sea level to 5341 m to and determined that draw volumes are reduced by approximately 0.5 mL for every 1000 m gain in terrestrial elevation.
