A 29-year-old man was brought to an emergency department by the United States Coast Guard with chief complaints of severe abdominal pain, right leg paresthesia and weakness following four deep air dives. Physical examination before recompression treatment was remarkable for diffuse abdominal tenderness and right leg weakness. The patient was diagnosed in the emergency room with type II decompre...
Hyperbaric therapy is the basis of treatment for pervasive development disorders. For this reason, the choice of the right therapeutic table for each case is critical. Above all, the delay in recompression time with respect to the first symptoms and to the severity of the case must be considered. In our experience, the use of low-pressure oxygen tables resolves almost all cases if recompression...
the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
in nutritional experiments the animals are kept in metabolic cage and are fed according to the planned interval times. a machine was designed and fabricated to feed the sheep every one or two hours. the machine operates with 220 volts electricity and the feed storing capacity is designed for three days feeding. the weight of sheep and type of feed determines the amount of feed required. by chan...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
INTRODUCTION First aid oxygen (FAO2) has been widely used as an emergency treatment for diving injuries, but there are few studies supporting its efficacy. METHODS 2,231 sequential diving injury reports collected by the Divers Alert Network (DAN) Injury database from 1998 to 2003 were examined. RESULTS 47% (1,045) of cases received FAO2. The median time to FAO2 treatment after surfacing was...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
