We present room temperature resonant tunneling of GaSb/AlAsSb double barrier resonant tunneling diodes with pseudomorphically grown prewell emitter structures comprising the ternary compound semiconductors GaInSb and GaAsSb. At room temperature, resonant tunneling is absent for diode structures without prewell emitters. The incorporation of Ga0.84In0.16Sb and GaAs0.05Sb0.95 prewell emitters lea...

The system is air conditioning system in operating room. The main objective of the system was implemented to provide air balance and temperature necessary conditions and to control airflow system for ventilation units in operating room. The operation room can be controlled with fuzzy expert system and describes the desired outputs. Input parameters such as temperature, humidity, oxygen and part...

We have described a challenging neural-network hardware implementation that would mate a 64x64-pixel infhred sensor directly on to a 3-dimensionally packaged set of neural processing chips with parallel input for high speed image processing. We now describe two enhanced schemes. In one the synapse (analog multiply device) resolution has been increased from 7to 8-bit without increasing the silic...

We report the first operation of a commercially available complementary metal-oxide semiconductor operational amplifier, .& liquid helium temperatuie. In addition, we have characterized several factors important to the practical application of such a circuit from room temperature down to 4.2 K. The temperature dependence and measurement techniques for -open-loop gain, input offset voltage, inpu...

In the late 1890, William Halsted, the American surgeon who started the use of gloves in the operating room devised a new operation for breast cancer called radical mastectomy (RM). The operation was called “radical” because it involved, not only the removal of the breast, but also the lymph nodes and muscles. Despite the drawback of disfigurement, this operation was the standard procedure for ...

background: long surgery causes hypothermia and increased bleeding and can increase the arterial blood lactate levels during anesthesia. it causes cellular hypoxia and its complications. considering the core temperature of the patient during surgery it can prevent hypoxia. this study aimed to compare the effects of different temperatures on the core temperature and the concentrations of lactate...

background: nursing project management is widely used in different aspects of the society. however, whether the nursing project management can control the infections in the operation room (or) is rarely reported. we evaluated the outcomes of surgical patients after implementing a nursing project management program to provide new scientific ways to manage the or infections. methods: overall, 382...
