1.1 Where am I? You wake up one morning in a hotel room. You have just arrived in Cozumel, Mexico for a short vacation. But right now, coming out of a dream, you do not quite remember this fact. The room is dark, there is only a dim light coming from the shutter on the right side somewhere at a distance. You do not know where you are. Or why you are there. It cannot be your home. Or is it? The ...

medical linear accelerators are one of the most widespread methods for cancer treatment. despite their advantages, unwanted photoneutrons are produced by high energy linacs. this photoneutrons are as undesired doses to patients and a significant problem for radiation protection of the staffs and patients. photoneutrons radiological risk must be evaluated because of their high let and range.in o...

Introduction: The aim of this study was to determine which technique of uncinectomy, classical or swing door technique.  Materials and Methods: Four hundred eighty Cases of sinusitis were selected and operated for Functional Endoscopic Sinus Surgery (FESS). Out of these, in 240 uncinectomies classical uncinectomy was done whereas in another 240 uncinectomies swing door technique was used. In...

This paper describes a system used in acoustic event detection task of the CLEAR2007 evaluation. The objective of the task is to detect acoustic events (door slam, steps, paper wrapping etc.) using acoustic data from a multiple microphone set up in the meeting room environment. A system based on hidden Markov models and multichannel audio data was implemented. Mel-Frequency Cepstral Coe cients ...

PERSONNEL HAZARDS FROM MEDICAL ELECTRON ACCELERATOR PHOTONEUTRONS" R. C. McCall, T. M. Jenkins, R. A. Shore and P. D. LaRiviere+ Stanford Linear Accelerator Center, CA, U.S.A. and Varian Associates? INTRODUCTION For medical accelerators, neutron penetration through the room entry door is the major personnel hazard. Most therapy accelerator rooms are designed with at least a rudimentary maze to ...

Grace Hall was vandalized early Sunday morning resulting in damage to several of its first floor facilities. The first floor men's room sustained the most extensive damage. A stall door was ripped from its hinges and its metal frame torn from the floor where it was anr.hored. Both were found in a heap of dented. twisted metal on the floor of the bathroom. The dents in the door and frame appeare...

We investigated individual differences in the stimulus control of navigational behavior in the water maze by comparing measures of place learning in one environment to measures of latent learning (via passive placement on the goal platform) in a novel environment. In the first experiment, 12 rats were trained to find a slightly submerged hidden platform at a fixed location in room A for 10 days...

ISSUE Research has often stressed the significance of reducing door movement during surgery for preventing surgical site infections. This study investigated the possible effect of a lean A3 intervention on the reduction of door movement during surgery in a university medical center in the Netherlands. INITIAL ASSESSMENT A digital counter recorded door movement during 8009 surgical procedures ...
