I knocked on Denise’s door, and a weak voice told me to come in. When I entered, Denise was lying in bed, barely able to lift her head from the pillow. Her body was skeletal, and her arms were the bruised color of cancer and chemotherapy. Intravenous lines dangled, as saline and morphine flowed into her veins. A breakfast tray sat untouched on the bedside table. The room smelled of sweat, sickn...

Lying supine, the technician uses my mask to bolt me to the treatment table. After he leaves the room, I feel alone, and at first, afraid. I see and hear the radiation machine move around me, but feel nothing. Minutes later, the door opens, and the mask is unbolted. This process is repeated almost daily for 2 months... After 2 weeks, the skin on my neck and inside my mouth becomes red, sore, an...

This paper describes a project that uses constructionist technologies to improve the quality of life of people with disabilities. Specifically, the project involves Logo programming as well as the assembly and utilization of the so-called GoGoBoard. The GoGoBoard is used in our project as the heart of an intelligent bedroom. In this room, a person with physical disabilities can control various ...

Some collective behavior during escape panic such as the ‘faster-is-slower effect’ and the irregular outflow are associated with clogging. The reasons for clogging appearance are investigated with a multi-grid model which is presented in previous work. The model implements finer discretization which leads to clogging effects in the dynamics. The effects of the exit width and the interactions ca...

For most healthcare information systems, passwords are the first line of defense in keeping patient and administrative records private and secure. However, this defense is only as strong as the passwords employees chose to use. A weak or easily guessed password is like an open door to the medical records room, allowing unauthorized access to sensitive information. In this paper, we present the ...

We present here a method for providing a mobile robot with learning capabi l i t ies. The method is based on a model of the environment with several hierarchical levels organized by degree of abstract i on . The mathematical structuring tool used is the decomposition of a graph into i t s k-connected components (k=2 and k=3). This structure allows the robot to improve navigation procedures and ...

1. A back-to-back cargo movement is generally understood as the transfer of loose goods from one truck to another---in its literal form, positioning two trucks with their backs to one another. Primitive variants involve laborintensive handling and placement of cargo on the ground during the transfer. This process inflicts serious time delays and damage to cargo and is widely avoided in modern t...

background:the door-to-needle-time (dnt) is considered a standard time for scheduling thrombolysis for acute st-segment elevation of myocardial infarction and this time can be reduced by minimizing the delay in starting thrombolytic treatment once the patient has reached to the hospital. this study was carried out on a sample of iranian patients with acute myocardial infarction to determine the...

When I was street homeless, the challenge was getting to see a general practitioner. So many obstacles were in the way—no address, out of area, no proof of who I was. It was as if I needed three forms of identification and a letter from God just to get past the receptionist. Surgery doors closed in my face, and excuse after excuse was given as to why I couldn’t see the doctor. I was sent to oth...
