The limits of Cushitic
(1980)
Gegenstände der Untersuchung sind genetische Gliederung und historische Rekonstruktion im Kuschitischen. Nach dem Kriterium gemeinsamer sprachlicher Innovationen sind folgende Schlüsse möglich: (1) Ik ist keine kuschitische, nicht einmal eine afroasiatische Sprache. (2) Es ist durchaus nicht sicher, daß die Burji-Sidamo-Gruppe (Rift-Valley-Kuschitisch) mit dem Tieflandkuschitischen einen genetischen Zweig - das Ostkuschitische - bildet. Die Burji-Sidamo-Gruppe kannte am engsten mit dem Agaw verwandt sein und mit ihm einen anderen genetischen Zweig - das Hochlandkuschitische - bilden. (3) Die Iraqw-Gruppe - und mit ihr vermutlich das gesamte Südkuschitische - gehört zum Tieflandkuschitischen und bildet keinen selbständigen Zweig des Kuschitischen. (4) Obwohl das Beja zweifellos eine afroasiatische Sprache ist, ist jedoch nicht zuverlässig bewiesen, daß es zum Kuschitischen gehört. Seine genaue Stellung zum Kuschitischen (dem Kuschitischen nächstverwandter Zweig oder nicht einmal dies?) bleibt noch zu klären. Die Erörterung und Beweisführung beruht auf Rekonstruktionen des Verbalsystems und der Kasus, auf einem Systemvergleich der Determinationselemente und der Genitivmorpheme sowie auf anderen syntaktischen und morphologischen Merkmalen. Auch einige Prinzipien der linguistischen Typologie wurden herangezogen. Es handelt sich um vorläufige Ergebnisse.
Phase transitions in nuclear matter A method for the description of spin-isospin phase transitions in nuclear matter is developed. It allows a complete description of the pion condensation phase transition in the framework of the Landau-Migdal Fermi liquid theory. The equation of the order parameter is derived and the condensation energy is calculated. We study the influence of pion condensation on the nuclear equation of state and the temperature dependence of pion condensation. NUCLEAR STRUCTURE Description of pion-condensed ground state by Green's function technique.
In order to elucidate what species among so many kind of marine organisms are likely to be consmed Iargely by the balaenopterid whales, the existing evidence on the food habits of baleen whales is reviewed. To meet with this primary purpose the report was mainly focussed on to describe qualitative aspects of food species having been known to date from the notable whaling grounds over the world rather than documenting quantitative subjects. One of interesting facts noticed throughout the contribution was that there exists fairly intense diversity in the assembly of food species composition by regions such as; northern hemisphere vs. southern hemisphere, Pacific region vs. Atlantic region, inshore waters vs. offshore waters, embayed waters vs. open waters, where the former usually shows more diversed complexity than the latter. The fact however suggests that although the composition of food species locally varies over the various whaling grounds, the food organisms as taxonomical groups are very similar one another even in locally isolated whaIing grounds when the food organisms and their assemblies are considered by the family or genus basis. In this connection many evidences given in the text may suggest that the balaenopterid whales as a whole may substantially live on quite simply compositioned forage assembly in comparison with tremendous variety of organisms existing in the marine ecosystems. One of important aspects of the baleen whales food must be found in their characteristics of forming dense swarms, schools, and/or aggregations in the shallower enough layers to be fed by the whales. The present and past status of larger baleen whales as the mighty monarch through their evolutional pathways may entirely depend upon the spatial distribution pattern of possible food organisms, i.e. the animal aggregations.
We present a unified formulation of the interaction of electrons with the electromagnetic field in heavy ion collisions, based on quantized interacting fields. This reduces the effort in treating many-electron systems substantially, as compared with the usual S-matrix theory. Both formalisms are shown to be equivalent. The simplification achieved by our new approach is demonstrated in detail for the example of quasi-molecular radiation.
In his magnum opus (Syntax and Semantics, Leiden 1978, henceforth: S&S) C.L. Ebeling makes a distinction between temporal gradation (pp 301-308 and 337-339) and temporal limitation (pp 311-315). In the case of temporal gradation “p , q”, the meaning “q” specifies the time during which the referent carries the mean-ing “p”.
Dynamics of Coulomb fission
(1980)
A general formalism is described for the treatment of Coulomb fission, within the framework of the semiquantal theory. We develop a model for the fission probabilities of levels excited in Coulomb excitation. This model contains penetration of the double-humped fission barrier, competition from gamma and neutron emission, and the spreading of the collective states into noncollective compound states. For 74184W + 92238U, the fission probability at θc.m.=180° is increased by a factor of 3.9, 3.3, and 2.0 at E/ECoul=0.77, 0.85, and 0.935, respectively, compared to the simplified sharp cutoff model used in earlier model calculations. The enhancement comes from barrier penetration. The damping of the fission probability due to spreading into noncollective compound states is small. Prompt Coulomb fission (near the distance of closest approach) is studied in a one-dimensional model. The results clearly imply that prompt fission is negligible. We have also studied the sudden approximation for collective rotational levels in connection with Coulomb fission. At high spins (I≈20), it leads to significant errors. Contrary to the basic assumption of the sudden approximation that the nuclear symmetry axis remains fixed during the collision, it is shown that Coulomb excitation results in a strong alignment of the nuclear symmetry axis perpendicular to the beam axis at small internuclear distances. NUCLEAR REACTIONS, FISSION Semiquantal theory of prompt and asymptotic Coulomb fission, study of double-humped barrier penetration, damping effects, neutron and γ emission. Calculated σ(Ep, θc.m.=180°).
I shall use the precise term 'interlinear morphemic translation (IMT) to designate the object of this study. [...] An IMT is a translation of a text in a language L1 to a string of elements taken from L2 where, ideally, each morpheme of the L1 text is rendered by a morpheme of L2 or a configuration of symbols representing its meaning and where the sequence of the units of the translation corresponds to the sequence of the morphemes which they render. [...] An IMT is needed whenever it is essential that the reader grasp the grammatical structure of the L1 text but is presumed to be so unfamiliar with L1 that he will not be able to do so merely with the aid of a normal translation and the context in which the text is cited. [...] The primary aim of an IMT is to make the grammatical structure of the L1 text transparent. The textual fluency of the IMT by standards of the L2 grammar is a subordinate aim at best.
In heavy ion collisions, the molecular single-particle motion may cause specific structures in the energy dependence of the cross sections which arise by the promotion of nucleons at level crossings according to the Landau-Zener excitation mechanism. In order to examine this effect in asymmetric heavy ion collisions, we have calculated level diagrams of the two-center shell model for the target projectile combinations 13C + 16O and 12C + 17O and analyzed with respect to inelastic excitation and neutron transfer. We select certain reactions as possible candidates for showing enhanced cross sections for nucleon excitation and transfer due to real and avoided level crossings near the Fermi level.
