a 35 year old diver comes to your office. he had hyperglycemia in his last check up. he asks if he can steel dive in spite of hyperglycemia. we reviewed the recent studies about diabetic persons who dive. recent studies have shown that well controlled diabetic persons may be permitted to dive, but if they have any problem such as diabetic nephropathy, retinopathy, neurological and cardiac probl...

To get suitable ladle slag which can avoid slag sticking onto the RH immersion tube during RH refining process of IF steel, the effect of composition on melting point and viscosity of RH refining ladle slag was studied by different additives which is based on CaO. The results of melting point and viscosity testing experiments indicates that, the melting point and viscosity of RH refining ladle ...

SUMMARY Firms frequently cooperate by exchar\ging valuable information informally. This paper presents empirical evidence on information trading in the U.S. specialty steel and steel mini-mill industry. Technical information is exchanged informally between firms, including direct competitors. Employees who trade information orient their trading decisions around the economic interests of their f...

The study of measurable and integrable selections from a correspondence (set-valued function) has been of interest for some time [e.g., see Aumann (1965), Hildenbrand (1974), etc.]. Here we take up the study of distributions of such selections. The motivation for doing this comes from Mathematical Economics [see Kannai (1970, section 7); the reader interested in the economic applications is ref...

When a non-interactive story is reread, the experience may change, even though the text remains the same. But what if the text is potentially different in each reading session, as is the case in an interactive story – how does rereading change in the context of interactive stories? In our earlier empirical studies of rereading we found that, surprisingly, readers of interactive stories reported...

We analyzed the effects of dopamine signaling on the temporal organization of rest and activity in Drosophila melanogaster. Locomotor behaviors were recorded using a video-monitoring system, and the amounts of movements were quantified by using an image processing program. We, first, confirmed that rest bout durations followed long-tailed (i.e., power-law) distributions, whereas activity bout d...

In standard arithmetic, if we, e.g., accidentally added a wrong number y to the preliminary result x, we can undo this operation by subtracting y from the result x+ y. A similar possibility to invert (undo) addition holds for intervals. In this paper, we show that if we add a single non-interval set, we lose invertibility. Thus, invertibility requirement leads to a new characterization of the c...

Perfectionists have excessively high standards and thus are prone to experience dissatisfaction and embarrassment. But what if they achieve perfection? The present study investigated in a sample of 194 university students how self-oriented and socially prescribed perfectionism predicted emotional reactions (satisfaction, dissatisfaction, pride, embarrassment) to imagined situations in which stu...
