    Notes: Summary Two hundred homosexual men were investigated for prevalence rates of syphilis, hepatitis A (HAV) and hepatitis B (HBV). A reactive Treponema pallidum haemagglutination test (TPHA) was found in 56.3% of the participants. In 81.7% HBV scromarkers were detected. Hepatitis B surface antigen (HBsAg) was present in 6.6%. Anti-HAV was found in 51.0%. Risk factors for acquisition of these infections are discussed.

    Detection of respiratory virus antigens in nasopharyngeal secretions from patients with acute respiratory disease by radio-immunoassay and tissue culture isolation (1984)

    Notes: Abstract An investigation was made of the sensitivity and specificity of four-layer radio-immunoassays (RIA) in the detection of adenovirus, respiratory syncytial virus, influenza virus types A and B, as well as para-influenza virus types 1, 2 and 3 from nasopharyngeal aspirates of 146 patients with acute respiratory disease. The sensivity of RIA was comparable with that of tissue culture isolation if the total number of positives is considered. The difference may have been caused both by a higher efficiency of the RIA for detection of inactivated or non-cultivable agents and by a higher efficiency of tissue culture methods if the samples contained only small amounts of antigen. Differences between the two antigen detection systems were found in particular with respiratory syncytial virus and influenza B virus. At present, the use of tissue culture isolation together with RIA is the optimal routine laboratory procedure for the diagnosis of respiratory infections.

    Mutants affecting position-effect heterochromatinization in Drosophila melanogaster (1982)

    Notes: Abstract The dominant suppressor Su(var)b 101 and the dominant enhancer En(var)c 101 were found to affect significantly white variegation in a strongly variegating line of the w m4 chromosome (w m4h ) which has been used as standard rearrangement for a genetic dissection of position-effect variegation (Reuter and Wolff, 1981). Both mutations were also shown to affect position-effect heterochromatisation in T(1;4)w m258-21 and variegation in all the rearrangements tested (white, brown, scute and bobbed variegation). These results suggest that the genes identified encode functions essential for the manifestation of gene inactivation in position-effect rearrangements. It seems also reasonable to assume that in all the rearrangements tested identical heterochromatisation processes lead to inactivation of the genes whose phenotype is variegated.

    Notes: Abstract The free charge carrier concentration as a function of the reciprocal temperature and the doping level [p(1/T)- andp(C)-characteristics] is calculated from the neutrality equation of a semiconductor containing positive or negativeU centers. The typical exponential laws and power laws of thep(1/T)- andp(C)-characteristics are given both for positive and negative correlation energy of the bound charge carrier pairs. Furthermore, the characteristics are evaluated differentially, in order to obtain criteria for the presence of negativeU centers in semiconductors.

    Notes: Abstract The trajectories of para-and ferromagnetic particles with velocities between 0.04 and 2.5 cm s−1 have been investigated in an HGMS model system with axial configuration. A single-wire system has been observed by a TV system. The trajectories were compared with the ideal (inviscid flow) and laminar (viscous flow) model. The results agree with laminar flow model.

    Notes: Abstract.  The ablation process of thin copper films on fused silica by picosecond laser pulses is investigated. The ablation area is characterized using optical and scanning electron microscopy. The single-shot ablation threshold fluence for 40 ps laser pulses at 1053 nm has been determinated to F thres=172 mJ/cm2. The ablation rate per pulse is measured as a function of intensity in the range of 5×109 to 2×1011 W/cm2 and changes from 80 to 250 nm with increasing intensity. The experimental ablation rate per pulse is compared to heat-flow calculations based on the two-temperature model for ultrafast laser heating. Possible applications of picosecond laser radiation for microstructuring of different materials are discussed.

    Notes: 2 clusters with about 1000 molecules per unit charge are accelerated to up to 120 keV kinetic energy for mask projective surface bombardment. Patterning is achieved via physical as well as chemical surface erosion. Very smooth eroded surfaces result for bulk natural diamond, silicon, and glass. Polycrystalline, strongly faceted CVD diamond films are effectively planarized. Submicron structures with various wall inclinations can be generated. Atomic force microscopy of individual impact structures reveals nanometer-sized hillocks instead of craters. The collective motion of the impacted surface material is considered crucial for the cluster impact-induced nanomodifications. Atomic ion beam lithography is considered for comparison.
