Blood can be collected from rats in a number of sampling locations. For instance, the tail vein is a superior location for blood sampling. However, the tail vein is thin so that it is sometimes hard to puncture. In addition, the tail vein has low blood flow and requires a long sampling time to get sufficient blood. The present report describes a simple blood sampling method, the vacuum blood co...

The internal structure of the colour flux tube (CFT) joining a quark pair in the confining phase of any gauge model provides an important test of the dual superconductivity (DS) conjecture , because it should show, as the dual of an Abrikosov vortex, a core of normal, hot vacuum as contrasted with the surrounding medium, which is in the dual superconducting phase. A general way to study the int...

The optimal milking cluster should milk as gently possible to minimize the mechanical effect on teat tissue at an performance and quality. objective of this study was investigate influence liner shape (round vs. triangular) type ventilation (claw mouthpiece chamber; MPC) vacuum end in MPC. Our hypothesis that affect MPC vacuum. Six Holstein Friesian cows were milked twice daily over 12 d with a...

Abstract The heat transfer characteristics of the collector tube is one cores a linear Fresnel reflector-solar thermal power generation system (LFR-CSP). In this paper, model reflective single-tube compound parabolic (CPC) established. light normal operating conditions during day, it found that direct irradiation (DNI) and loop length exert significant effects on collection loss performance ref...

OBJECTIVE This study aims to explore the effect of vacuum sealed drainage on the recovery of gastrointestinal function in gastric patients after radical gastrectomy. METHODS One hundred and twenty patients who received radical for gastric cancer were randomly divided into two groups. Patients in the control group received continuous gastrointestinal decompression to drain the gastric juices a...

Low current x-ray tubes operating at 25–40 kV have been developed using monolithic carbon nanotube CNT cold cathodes as electron sources. The authors have tested CNT cathodes from various sources. They were systematically evaluated and conditioned in a vacuum chamber and then went through high temperature baking and high voltage processing of standard tube production processes. Acceptance crite...

Tank liquid ammonia (Ohio Chemical and Manufacturing Company) was distilled from sodium shavings into a tube of about 120 cc. volume. This was equipped with a thermocouple well, inlet and outlet side arms protected with calcium chloride and phosphorus pentoxide drying towers, and a standard taper cap containing a mercury seal stirrer. A current of dry nitrogen could be passed through the tube, ...

This paper describes the engineering and development of a process to electrically and mechanically bond a large area, backlit charge-coupled device (CCD) sensor to a metallized substrate, using a materials system compatible with a high vacuum tube configuration. The CCD sensor is used in light sensor and digital camera devices. Currently, CCD devices are mechanically bonded to substrates using ...

BACKGROUND The purpose of this study was to assess specific vacuum-venipuncture skills and the influence of the time involved in skin puncture and blood collection. METHODS Thirty subjects undergoing venipuncture in which video analysis was possible were included. These procedures were carried out by four nurses and recorded with a digital camera. Venipuncture skills classified by our observa...
