A new device for stopping or reducing potentially irritating or harmful emissions from surfaces indoors is described. The device is a surface emissions trap prototype and consists of an adsorbent sheet with a semipermeable barrier surrounded by two thin nonwoven layers. The trap may be applied directly at the source of the emissions e.g. at moisture-affected floors and walls, surfaces contamina...

background: needle stick accidents  are a serious health  risk  for blood-borne infections among health-care workers(hcws). objective: to determine the frequency of needle stick injuries (nsis)  among hcws. material & methods: a cross-sectional study was conducted in  behesti hospital  of kashan from september 2012 to march 2013. data were collected using  a questionnaire. result: needle stick ...

In the last decades an important number of research papers published on nano chip electrode and cathode electrochromic materials. Tantalum (Ta) with so high melting point can be as a good candidate for the future of nano chip devices. However, its surface has not enough trap centers and/or occupation states, so nitrogen ions exposed on Ta surafce, may solve this problem. For this purpose, in th...

A needle-type extraction device is one of the promising sample preparation devices for the gas chromatographic (GC) analysis of various organic compounds. The most remarkable advantage of this device is a simple and rapid desorption of the analytes by direct insertion of an extraction needle into a conventional GC injection port. In this review, fundamental aspects of the needle-type extraction...

A transmission-type light-trap silicon radiometer has been developed to hold the NIST spectral power and irradiance responsivity scales between 406 nm and 920 nm. The device is built from replaceable input apertures and tightly packed different-size silicon photodiodes. The photodiodes are positioned in a triangular shape tunnel such that beam clipping is entirely eliminated within an 8 field-o...

This paper reports a novel remotely actuated device for transrectal prostate biopsy, designed for use in a conventional high-field MRI scanner. The device provides three-dimensional MRI guided biopsy needle placement with sub-millimeter accuracy under physician control. Its compact size enables use in both closed and open configuration MRI scanners. Preliminary in-vivo canine experiments demons...

A navigation system for radiological interventions (CAS-One IR, CAScination, Bern) has been used to evaluate three different needle insertion methods on a non-rigid liver phantom. The insertion methods under investigation include: navigated free-hand needle insertion, aiming device-based insertion with active depth control and aiming device-based needle insertion with passive depth control. For...

A SensAble Omni force feedback device has been modified to increase the face validity of a needle insertion simulation. The new end effector uses a real needle hub and shortened needle shaft in place of the Omni's pre-fitted pen shaped end effector. This modification facilitates correct procedural training through the simulation of co-located visual and haptic cues in an augmented reality appro...
