Abstract In the foreseeable future, geothermal exploitation from hot dry rocks (HDR) using a horizontal well will bear potential. Thus, in-depth studies should be conducted on selection of injection-production scheme (IPS) and working fluid, design reinjection parameters, optimization wellbore structure materials, analysis geological settings. This paper proposed fully coupled model to study ab...

OBJECTIVE The purpose of this study was to compare the reliability of the lateral fluoroscopic view and several contralateral oblique (CLO) views at different angles in visualizing and accurately predicting the position of the needle tip at the point of access in the posterior cervical and cervicothoracic epidural space. DESIGN After the epidural space was accessed but before confirmation wit...

BACKGROUND Injection force is a particularly important practical aspect of therapy for patients with diabetes, especially those who have dexterity problems. This laboratory-based study compared the injection force of the SoloSTAR® insulin pen (SoloSTAR; sanofi-aventis) versus other available disposable pens at injection speeds based on the delivered volume of insulin released at the needle. M...

A simple device for making pressure microinjections into the brain, its application for delivery of a tracer substance, biotin dextran amine, and an example of the resulting axonal transport are described. The device is based on the use of a Luer tip Hamilton microliter syringe mated directly to the plastic hub of an injection needle assembly in which the metal needle has been replaced by a gla...

This paper describes an innovative alternative to manual procedures for the application of carbon fiber and resin injection in concrete surfaces in tunnels. It is based on a specially designed light-weight integrated tool for automatic application of Fiber Reinforced Polymer (FRP) and epoxy resin injection. Vision and laser telemeter sensing are integrated into the tool to assure precise inspec...

We report on a quantitative use of Kelvin probe force microscopy (KPFM) for the analysis charge injection in thin oxides. Here, dielectrics are investigated through an atomic tip that is used as movable (virtual) top-electrode. The injected and read-out respectively by alternating direct contact with oxide, non-contact surface potential imaging. difference (CPD) between microscope oxide to meas...

Single film retrograde umbilical aortography was used successfully in confirming the diagnosis of hypoplastic left heart in three neonates. The method involves injecting Renografin 75% (1.25 cc/kg body weight) into the umbilical artery catheter according to the following sequence. First, the tip of the catheter is positioned at the level of the ductus arteriosus. The infant heart beats are then...
