TY - JOUR A1 - Köhler, H. A1 - Becker, Charles R. T1 - Optically active lattice vibrations in Bi\(_2\)Se\(_3\) N2 - The preparation of Bi2Sea single crystals with low free carrier densities allowed an investigation of the lattice vibrations to be carried out from the reflectivity of cleavage planes at nearly normal incidence of the radiation (E ~ c). The experimental results ean be explained with two classical oscillators, whose eigenfrequencies oceur at 92 and 69.5 cm-I. The static dielectric constant was determined to be 100 ± 10 for E ~ c.

A1 - Herth, Werner T1 - Structural and biochemical studies of the primary nucleus of two green algal species, Acetabularia mediterranea and Acetabularia major N2 - Primary (giant) nuclei of the green algae Acetabularia mediterranea and A. major were studied by light and electron microscopy using in situ fixed material as well as manually isolated nuclear components. In addition, cytochemical reactions of nuclear structures and biochemical determinations of nuclear and cytoplasmic RNA and of genome DNA content were performed. The data obtained and the structures observed are interpreted as demonstralions of transcriptional activities of different gene classes. The most prominent class is the nucleolar cistrons of precursors of ribosomal RNA which occur highly repeated in clusters in the form of regularly alternating intercepts on deoxyribonucleoprotein axes of transcribed rDNA, the fibril-covered matrix units, and the fibril-free "spacer" segments. A description and a classification of the various structural complexes which seem to represent transcriptional activities is given. Quantitative evaluations of these arrangements are presented. The morphology and the dimensions of such structures are compared with the RNA molecular weight determinations and with the corresponding data reported from various animal cell systems. It is suggested that the formation of the giant nucleus is correlated with, and probably due to, an enormous amplification of transcriptionally active rDNA and packing of the extrachromosomal copies into the large nucleolar aggregate bodies.

Der Zusammenhang zwischen direkter Skalierung, Bezugssystemtheorie und phänomenadäquater Verwendung von Skalen wird diskutiert. Jedes Gruppenmitglied (untersucht wurden Schulklassen) stuft seinen Kontakt zu jedem anderen ein. Daraus ergibt sich ein Sozioprofil, dessen Repräsentanz für das Sozialverhalten beispielhaft an Extremgruppen gezeigt wird. Es kann nachgewiesen werden, daß die bis jetzt unterstellte Trennung gemischtgeschlechtlicher Gruppen in zwei eingeschlechtliche Untergruppen ein methodenabhängiges Ergebnis der Wahlverfahren Morenoscher Prägung ist. N2 - The authors are not in favour of using questions containing problems of personal values in sociometry. The authors suggest a method that scales concrete interaction-behaviour (speaking and feeling angry). The connection between direct scaling, frame of reference theory and the use of scales adequate to the phenomena is discussed. Each member of the respective group rates his or her contact to each other member of the group. On the basis of these ratings a "socio-profile" is set up the representativeness of which for social behaviour is demonstrated by giving examples of extreme groups. The authors have adduced the evidence that the hitherto assumed separation of mixed groups (members of both sexes) into two uni-sexual sub-groups is a result due to Moreno's method of rating. (C.

A1 - Sebald, Walter T1 - Identification of two products of mitochondrial protein synthesis associated with mitochondrial adenosine triphosphatase from Neurospora crassa N2 - Soluble mitochondrial ATPase (F1) isolated from Neurospora crassa is resolved by dodecylsulfate- gel electrophoresis into five polypeptide bands with apparent molecular weights of 59000, 55000, 36000, 15000 and 12000. At least nine further polypeptides remain associated with ATPase after disintegration of mitochondria with Triton X-100 as shown by the analysis of an immunoprecipitate obtained with antiserum to F 1 A TPase. Two of the associated polypeptides with apparent molecular weights of 19000 and 11000 are translated on mitochondrial ribosomes, as demonstrated by incorporation in vivo of radioactive leueine in the presence of specific inhibitors of mitochondrial (chloramphenicol) and extramitochondrial ( cycloheximide) protein synthesis. The appearance of mitochondrial translation products in the immunoprecipitated A TPase complex is inhibited by' cycloheximide. The same applies for some of the extramitochondrial translation products in the presence of chloramphenicol. This suggests that both types of polypeptides are necessary for the assembly of the A TPase complex.

Entscheidungen von 8- bis 14jährigen Schülern zeigten, daß sich lagebedingte Wahlen als orientiert am Erwartungsmaximum bezeichnen lassen. Die Beziehung zwischen Orientierung am Erwartungsmaximum und den Variablen Alter, Schulzugehörigkeit und Vorerfahrung erwies sich als positiv. Weiterhin konnte die Abhängigkeit der Wahlhäufigkeit des Erwartungsmaximums von der Hervorgehobenheit des Erwartungsmaximums nachgewiesen werden. Die Gültigkeit des objektiven Erwartungsmaximierungsmodells mußte aber wegen verschiedener Befunde eingeschränkt werden. N2 - Previous investigations on the decisive behabiour of children allow two interpretations of so-called situation-related choices. Decisions of students aged 8 to 14 years showed that choices due to situations may be regarded as oriented toward the expectation maximum. The relation between this orientation and variables such as age, type of school and previous experience proved to be positive. Furthermore it was verified that the frequency of choice of the expectation maximum depends on the accentuation of the expectation maximum. However, the validity of the objective model of expectation maximation had to bc restricted because of various findings KW - Psychologie Y1 - 1975 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:bvb:20-opus-43784 ER - TY - JOUR A1 - Franke, Werner W.
