The door-to-needle time is an important goal to reduce the time to treatment in intravenous thrombolysis. Objective Analyze if the inclusion of an exclusive thrombolytic bed reduces the door-to-needle time. Method One hundred and fifty patients admitted for neurological evaluation with ischemic stroke were separated in two groups: in the first, patients were admitted in the Emergency Room for i...

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...

Abstract Several efforts to mitigate the spread of COVID-19 and use a minimum three layers masks, it is also necessary apply physical distancing in all work activities both indoors outdoors. This study describes one that researchers can do prevent COVID-19, namely, designing room capacity detection system equipped with temperature detector. The research method an experiment focusing on detector...

Studies of the testing effect have shown that retrieval significantly improves learning. However, most of these studies have been restricted to simple types of declarative verbal knowledge. Five experiments were designed to explore whether testing improves acquisition of route knowledge, which has a procedural component consisting of actions to be performed at decision points (Golledge, 1991). ...

Door is a very significant element as it enables person to enter house or room. Though identifying doorway an easy task for regular person, robots visually impaired people challenging task. To overcome this challenge, we have proposed door detection method. Our method based on Prewitt edge and Harris corner detector. Here, are using number of predefined rules detect the doorframe correctly. est...

background: in the steel industry, coke-fueled furnaces are used for smelting iron ore to produce cast iron are considered as sources of annoying noise.this study aims to evaluate the noise pollution blast furnace and sound source characteristics in order to present noise control measures in the steel industry. methods: measurement of noise level and its frequency analysis was performed using s...

The number of public displays is rapidly increasing due to their decreasing prices and the advantages of their dynamic behavior. If the displayed content depends on aspects like the time or the location, these displays are called situated displays. This paper discusses two fields of application for situated displays. One field of application is the displaying of information about a room in comb...

A man walks into a men’s room and observes n empty urinals. Which urinal should he pick so as to maximize his chances of maintaining privacy, i.e., minimize the chance that someone will occupy a urinal beside him? In this paper, we attempt to answer this question under a variety of models for standard men’s room behavior. Our results suggest that for the most part one should probably choose the...

heater. This system is adequate for rooms with a capacity of up to about 16 m3 and for temperatures of up to 40°C. Temperature recording is by a Cambridge recorder which is mounted externally and, over a period of over one year since the installation of the hot room, the internal temperature has remained constantly at the set temperature (37°C). Local temperature variations within the hot room ...
