Ion-optical calculations are often performed as a first step when designing magnetic systems. As a second step Monte-Carlo simulations are performed of EVaporation Residue (EVR) trajectories through the separator, varying parameters like target thickness, gas pressure and magnet field. Such a program is very useful to optimize all system parameters and to plan and to prepare experiments. The ne...

in this project creep feed grinding process of gas turbine blade root is investigated with the aim of consistant and controlable production. inthispaper, effectiveness of creep feed grinding process prometers suchas wheel speed, workpiece speed, grind depth and dresser speed are investigated. this investigation include their interaction on thelob of gas torbine blade root, as amajor cause of a ...

As a clean and energy-saving natural gas purification separation device, the supersonic separator's internal gas-liquid mechanism needs to be explored. However, complex three-field (gas, droplet, liquid film) two-phase liquid) condensation flow challenges numerical modeling. Most studies are limited tracking phase droplets ignore effects of film change on water vapor removal. In present study, ...

Wireless applications have become a common part of daily life. Whether it is mobile phones, the Wi-Fi router at home, the keycard which has replaced the car key, a radio frequency identification access system to a building or a Bluetooth headset for your computer or phone, the means of modern wireless data exchange is an omnipresent technology. In sports, the market is in its infancy for wirele...

OBJECT We arranged a mini-invasive surgical approach for implantation of paddle electrodes for SCS under spinal anesthesia obtaining the best paddle electrode placement and minimizing patients' discomfort. We describe our technique supported by neurophysiological intraoperative monitoring and clinical results. METHODS 16 patients, affected by neuropathic pain underwent the implantation of pad...

ell death in the stalk of Dictyostelium discoideum , a prototypic vacuolar cell death, can be studied in vitro using cells differentiating as a monolayer. To identify early events, we examined potentially dying cells at a time when the classical signs of Dictyostelium cell death, such as heavy vacuolization and membrane lesions, were not yet apparent. We observed that most cells proceeded throu...

In earlier papers, NIST proposed a standard illumination source and optical filter targets with which to assess the state-of-the-art of display measurement. The Display Measurement Assessment Transfer Standard (DMATS) was designed to present the display metrologist with a rectangular array of targets such as color filters, polarizers, and grilles, back-lighted by uniform illumination, to be mea...

At TNO Automotive in Helmond the Generic Driving Actuator (GDA) is developed. The GDA is a device capable of driving a vehicle fully automatically using the same interface as a human driver does, i.e. using the actual steering wheel, fuel paddle and braking paddle. For such an autonomous robot, safety and fault-tolerance requirements are of the utmost importance, since failure of the robot can ...

Substances in evacuated blood-collection devices produce gas-chromatographic peaks with retention times similar to those of drugs. All tubes tested except the serum separator tubes contained tris(2-butoxyethyl) phosphate, as determined by mass spectrometry. In addition, the partition coefficient during the solvent-extraction step increased for some drugs by as much as 40%, while for other drugs...
