Defects in semiconductors: some fatal, some vital.

REVIEW The role of defects as essential entities in semiconductor materials is reviewed. Early experiments with semiconductors were hampered by the extreme sensitivity of the electronic properties to minute concentrations of impurities. Semiconductors were viewed as a family of solids with irreproducible properties.

[Type 2 Streptococcus suis (R-Streptococci) as pathogens of occupational diseases. Report of a case and a review of the literature].

Report on the second human case of a Streptococcus suis type 2 (group R streptococci) infection in the GDR. The patient, a 33-year-old butcher, fell ill with an acute meningitis and an initial myocarditis. Group R streptococci were isolated from cerebrospinal fluid and blood.

Intoxicated and bad drivers: subgroups within the same population of high-risk men drivers.

Three groups of men drivers in the state of Washington were compared: those who had been arrested for driving while intoxicated (DWI group, N = 172), those who had received multiple nonalcohol-related violations or who had been involved in traffic accidents (high-risk drivers, or HRD group, N = 193) and a representative random sample of the general driving population of men in the state (GDP group, N = 154). Subjects completed a questionnaire assessing demographic, drinking, driving attitude, personality and hostility measures. The HRD and DWI groups were generally more deviant than the GDP subjects.

An objective method for the assessment of psychological and social problems among epileptics.

Numerous investigators have identified psychological and social problems among epileptics and in many instances, these appear to be more debilitating than the seizures themselves. However, assessment of these problems has most frequently been done by subjective means and when objective tests have been used, they were almost always developed for and standardized on populations other than epileptics. The development of the Washington Psychosocial Seizure Inventory (WPSI) is presented in this paper.

[The degree of contamination with HBs-antigen (Australia antigen) in insulin using diabetics].

In 105 patients injecting themselves insulin of the diabetes department of the municipal hospital Dresden-Neustadt with an average age of 63.3 years the HBs-antigen was determined for the purpose of testing the degree of contamination. Hereby in no patient positive accidental findings were established.

Group embedded figures test performance as a predictor of cognitive impairment among alcoholics.

The present study investigated the sensitivity of the Group Embedded Figures Test (GEFT) as a predictor of cognitive impairment among alcoholics. The GEFT, Shipley-Hartford, and Memory-for-Designs tests were administered to 90 male alcoholics. GEFT performance correlated significantly with measures of impairment even when the influence of age and education were controlled.
