Understanding the means of acquisition, sources, and reservoirs of nosocomial pathogens is crucial for developing methods to reduce the incidence of nosocomial infections. The article in this issue by Graman et al1 highlights the continued importance of the environment, especially water sources, as a reservoir for nosocomial pathogens. Important water reservoirs in the hospital include potable ...

Most nonsignalized T-shaped intersections permit U-turn movements, which make the traffic conditions of intersection complex. In this paper, a new cellular automaton (CA) model is proposed to characterize the traffic flow at the intersection of this type. In present CA model, new rules are designed to avoid the conflicts among different directional vehicles and eliminate the gridlock. Two kinds...

The multimode dynamics of vertical-cavity surfaceemitting lasers with different active-region diameters was measured under subnanosecond electrical excitation (800-ps pulse duration, 100-ps risetime). The dynamics is characterized by the delayed onset of higher order modes which have a turn-on delay that is dependent on the active-region diameter and the excitation parameters. A simple model th...

---In this paper a thorough investigation of resistive logic gate DCI has been made. The current equations of this gate at each stage have been deduced. The dynamic response of this DCI gate has been obtained by the computer-simulation. Our concept of turn-on delay has been introduced. The effect of overdrive current on turn-on delay for resistive logic gate has been shown. This will provide a ...

introduction: pulmonary tuberculosis is major problem worldwide and it is estimated one third the world population are already infected and each year 9 million people develop full blown tuberculosis of these 3 million die of the disease, annually. delay in diagnosis and treatment are major problems that play a significant role in all aspect of the disease from patient treatment to transmission ...

Median U-turn intersection treatment (MUTIT) has been considered an alternative measure to reduce congestion and traffic conflict at intersection areas. The MUTIT is sometimes difficult to implement in the field because it requires wide median on arterials for U-turn vehicles. The objective of this study is to introduce an unconventional U-turn treatment (UUT) for intersections which requires l...
