Algebra Interview 1 The first interview began with Edwards asking “What is mathematics?” By asking follow-up questions as needed, Edwards made sure each student said something about the nature and role of definitions in mathematics. After that introductory discussion, each student was handed the following definition. Binary operations were being studied in class, but the definition of group had...

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...

This chapter is a reflection on the use of computers in the author’s time as a secondary school student, and then subsequently five years later as a qualified teacher of Information Technology. Despite the uneven teaching of computing in the 1980s low student enrolments, and the marginalization of the subject, computing flourished in the 1990s. With ever increasing enrolments for computing subj...

This paper uses a unique data set to measure peer effects among college roommates. Freshman year roommates and dormmates are randomly assigned at Dartmouth College. I find that peers have an impact on grade point average and on decisions to join social groups such as fraternities. Residential peer effects are markedly absent in other major life decisions such as choice of college major. Peer ef...

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...
