The generating functions which represent the p p data from 50 to 303 GeV/ c are used as analog grand partition functions and notions of analog pressure, specific volume, equation of state and critical point are explored. Also l-plane singularities are disdussed in this connection. (auth)

We introduce a modified SO(3) model of weak- and electromagnetic-interaction symmetry. The model is renormalizable and reproduces the usual theory of weak interactions. Four additional heavy leptons and five additional quarks are necessary. The electromagnetic charge radius of the neutrino is calculated in the $\ensuremath{\xi}$-limiting procedure and a finite result is found.

Internal stresses have been calculated in deformed steels by tension containing spheroidal or pearlitic cementite on the basis of a continuum model by assuming that the cementite is non-deformable and the accumulated internal stresses are unrelaxed. The maximum principal stress in cementite is tensile and higher in particles with their longest axis oriented more closely along the tensile axis, whereas the minimum principal stress is compressive and its magnitude is larger in the particles aligning more normal to the tensile axis. The angular dependency of the internal stress becomes stronger as the particles become flatter. These tendencies account for the geometric features of cementite cracking and kinking observed in spheroidized and pearlitic steels. On the other hand, the work hardening of the steels results from the average internal stresses in the ferrite matrix, which are balancing the opposite stresses in the particles. These stresses increase linearly as plastic straining develops and depend insensitively on the morphology of the particles.

The absolute structure of oleuropein was proved to be 1 through the chemical correlation of the glucoside with asperuloside of known absolute configuration. In connection with this experiment the absolute configurations of kingiside and morroniside were established as 4 and 5, respectively.

The beam-mode expansion method used in the discussions of the diffraction of a Gaussian wave beam through an aperture is applied to a system of two circular or square aperture stops, and the analytical expressions of the power transmission and conversion coefficients of a fundamental mode through the system are obtained. By using these expressions, the optimum incidence conditions that maximize the power transmission coefficient of the fundamental mode can be known. These conditions coincide formally with those obtained by Kogelnik and Yariv for an incident wave having a prolate spheroidal-wave function distribution. Both circular and square geometries can be analyzed in the same way.

As2S3 films were exposed to band-gap illumination both at 290 and 77 K alternately, and after each exposure optical and X-ray measurements were carried out. It has been clarified that the reversible photodarkening should be attributed to the reversible change in local order of the network.

Out of 393 cases of low back pain with sciatica treated surgically, 55 (14%) cases were teenagers.Protruded discs were removed in 41 cases and caudal tumors in 3 cases, and in the remaining 11 cases no abnormal findings were found in the spinal canal.The results of operations were obtained in 40 cases, of which 36 cases (90%) showed satisfactory results, being far superior to those of cases treated conservatively.

The problem of the reflection and transmission of obliquely incident electromagnetic waves by an inhomogeneous plasma slab moving parallel to the magnetostatic field is discussed. For the analysis of the problem, an inhomogeneous plasma slab is subdivided into a number of thin homogeneous layers, and the easier problem of the reflection and transmission by the stratified plasma slab is solved instead of directly treating the wave equations for an inhomogeneous plasma slab. For linear and parabolic electron density profiles, the reflection properties of the moving inhomogeneous magnetoplasma slab are investigated quantitatively with the aid of numerical examples.

SUMMARY Comparative anatomical observations of the brain stem of the various mammals led us to note some remarks on variance in the cellular elements, the correlation with the central gray or with the posterior hypothalamic nuclei, and on the peculiar cell groups described in the literature. They may be of value for coming experimental researches. 1) As to the variance of cellular make-up in various levels of the subnuclei, the minute cell count in such nuclei of rodents reveals that in three main subnuclei, i. e. R.gc, R.P.c and R.P.o of Meessen and Olszewski's denomination in the realm of reticular formation, the total number of cells shows a general tendency of increasing oralward, especially concerning the smaller cell type, while in the parvocellular nuclei, R.pc and R.pca, the smaller cells get reduced at the profit of increasing medium-sized cells oralward. These variances in the cell types in various sectioning levels concerning each nuclei stand almost in the same relationship in all the animals observed. 2) Cellular correlations between the midbrain reticular formation and the periaquaeductal gray substance were noticed especially in two places, namely at the meso-diencephalic and meso-rhombencephalic regions of transition. In the lastly named region, the attention was given to the so-called nucleus supratrochlearis bearing several subnuclei in within. The mediodorsal portion of the region is so far somewhat differing in cellular make-up, as the portion of some animals lets prove resemblance with the reticular nuclei. This homology in cellular make-up is also traceable in the former region. 3) The medial and the lateral part of the nucleus loci caerulei embedded in the reticular formation (nucleus ventralis et lateralis brachii of Winkler and Potter) were studied more minutely, where the secondary degeneration occurred seemingly after long survival period following destruction of some parts of the diencephalon, especially of the hypothalmic b-sympathetic zone. The medial portion, Coe2, seems to receive impulse from the ipsilateral hypothalamic region, while the lateral portion, Coe3, from the contralateral hypothalamic region. Thereby it was pointed out that there still avails dubiousness concerning whether they ought to be looked upon as a part of the nucleus loci caerulei or not. 4) The nucleus perpendicularis formationis albae was established in cases of several mammals, of all material most distinctly in the Indian elephant. This nucleus seems to stand in correlation particularly intimately with the medial longitudinal bundle, otherwise, with the paramedian reticular nuclei. 5) In the light of the cellular component of the nucleus retrofacialis and the accessory facial nucleus, we can put aside several types among animal species examined, especially from the view-point that the former nucleus ought to be accepted as the correspondent to so-called “dichte Formation” of the ambiguus nucleus in some German authors' interpretation while the latter represents a participant of the facial nucleus to the major part. Concerning the oral part at the least, however, the cells of the so-called accessory facial nucleus much resemble to the trigeminal motor nucleus in some animals, another time to the large cells of the reticular formation in certain another animals and still another time to cells of the abducens nucleus as was already mentioned from other side.

Having noted an important role of image stress in work hardening of dispersion hardened materials, (1,3) the present paper discusses a method of calculating the average internal stress in the matrix of a material containing inclusions with transformation strain. It is shown that the average stress in the matrix is uniform throughout the material and independent of the position of the domain where the average treatment is carried out. It is also shown that the actual stress in the matrix is the average stress plus the locally fluctuating stress, the average of which vanishes in the matrix. Average elastic energy is also considered by taking into account the effects of the interaction among the inclusions and of the presence of the free boundary.

(1) Piestic water of Daisen Volcano is recognized in Nawa Mud Flow and in Mikuriya Conglomerare. It looks like promising that Mizoguchi Tuff Breccia contains a pretty deal of ground-water.(2) Several springs are in (i) the Older Andesite (fissure water), (ii) Mikuriya Conglomerate and Nawa Mud Flow, and (iii) debris. The yield coming out of (i) is the greatest of all. Both produces of (ii) and (iii) are free surface water in nature.(3) This paper deals with two ground-water areas. One is, in the south of this district, a ground-water basin; another is, in the north, a underground valley which runs in the west. The latter is smaller than the former in the ground-water storage.

Work hardening of long range character for materials with strong inclusions was considered for the case in which plastic relaxation occurs by means of prismatic punching around the inclusions. The model used was a modification of the punching mechanism proposed by Ashby. The stress at an inclusion and the elastic energy arising from the presence of dislocation loops were calculated by using continuum mechanics. The balance between the driving force forprismatic punching produced by a decrease of the elastic energy due to prismatic punching and the retarding force arising from the frictional stress led to a stress-strain relationship after punching. It was found that work hardening was appreciable after considerable punching, although the derivation from linear hardening was significant. The elastically stiffer the inclusion the smaller is the strain required to initiate prismatic punching, but the larger is the increment of flow stress with plastic strain.

Two cases of dysostosis cleido-cranialis with coxa vara were reported. The coxa vara were operated with Pauwels' Y-osteotomy which resulted in success.

Als Fortsetzung eines Berichtes von 1963 werden neue Ergebnisse auf dem Gebiet der Allyl-Ubergangsmetall-Komplexe11 mitgeteilt. Neben Synthese und Umwandlungen dieser Verbindungen werden Fragen der Bindungsbeziehung zwischen Metall und Allylgruppe diskutiert. Auf der Basis von Allyl-Ubergangsmetall-Verbindungen lassen sich verschiedenartige, bei der Umwandlung von 1,3-Diolefinen und auch Olefinen in homogener Phase hochst selektiv wirkende Katalysatoren zuchten, die als Matrize „nackte” Metallatome oder aber zusatzlich mit einzelnen Liganden verbundene Metallatome enthalten.22

Memory (lock-on) phenomena observed in semiconducting glasses of the AsTeGe system have been investigated by electrical, calorimetrical and X-ray methods. Some differences between the memory process observed in high-As glasses and that in low-As glasses have been shown, which include both the waiting time for the process and the growth behaviour of the conductive filament formed between the electrodes. A strong correlation between the waiting time and the crystallization rate has also been indicated for their dependences on both the composition of the glass and the temperature. Finally, the kinetics of growth of the conductive filament during the memory process has been discussed using a simplified model, based on the ionic behaviour of the constituent elements in switch-on plasma, which explains well the polarity dependence of the filament growth.

The form of the Regge trajectory, the graph of the complex angnlar momentum alpha (t) as a function of the square of the momentum transfer t, is studied in field theory within the framework of the ladder approximation in the crossed channel. To order g/sup 2/, the trajectory is unbounded in the region t approximately 4m/sup 2/, but inclusion of the higher-order terms in jectory that resembles that expected from potential scattering. The various relations between g/sup 2/, alpha (t), and the exchanged mass are discussed. (auth)

Anomalous decrease in optical density has been observed in a flash-evaporated As2S3 film after exposure to visible light. This effect has been investigated by X-ray diffraction and electron micrograph methods, which suggests that it is ascribed to photodecomposition of the film.
