The objective of this research was to investigate the degree to which automobile doors (especially police cruiser doors) may be used as protection by police officers when under handgun attack. This is a vital question, since the cruiser door is often the only defense a police officer has when encountering gunfire. Data were collected on door penetration capabilities of 3 calibers of handguns (s...

AIM As door handles represent a transmission route for viruses and micro-organisms, a door opening and closing mechanism should be developed without manual operation. METHOD To solve the problem, a device for opening the door with the help of a foot pedal was built into the door leaf. RESULTS The design enables mechanical opening of the door with a foot pedal without manual operation. Subse...

BACKGROUND Little is known about the components of door-to-balloon time among patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention. We assessed the role of time from hospital arrival to ST-segment elevation myocardial infarction diagnosis (door-to-activation time) on door-to-balloon time in contemporary practice and evaluated factors tha...

In this research we try and implement communication system using the metaphor of a door on the World Wide Web (WWW) as a media for novel types of informal communications. We call those informal communications through a door ”on-door communications.” As an on-door communication system, we have designed and implemented a system for a chat at a net door. One has a door page on WWW and a chat syste...

DOOR syndrome is a rare multisystem genetic disorder, consisting of deafness (sensorineural), onychodystrophy, osteodystrophy, and mental retardation. Seizures reported frequently in this condition are often refractory to treatment.

Several recent studies have suggested that cues that predict outcomes elicit a feedback-related-like negativity (FRN-like negativity) reflecting initial appraisals of whether desired outcomes are probable. Some other studies, however, have found that the cues that predict outcomes elicited event-related potentials (ERPs) that reflect the expectation to outcomes (e.g., outcome expectations). Giv...

Introduction Imagine, for a second, a doorman that behaves as automatic doors do. He does not acknowledge you when you pass by, or approach. He gives no hint which door can or will open—until you wander within 10 feet of the door, whereupon he flings the door wide open. If you arrived after hours, you might stand in front of the doors for awhile before you understood that the doors are locked, ...
