Tide-induced reworking of planktonic foraminifers on the outer shelf and slope off the Miyako Island, southern Ryukyus, Japan: Preliminary results
Significance of sediment reworking to a shallower environment is preliminarily discussed by occurrences and oxygen isotopes of planktonic foraminifer (Globolotalia inflata) tests collected from the sea bottom sediments on the insular shelf to slope, off the Miyako Islands, southern Ryukyus, Japan. The isotopic data and comparison with the present water temperature-depth profile indicate that vertical distribution of G. inflata with size of 300-355µm ranges from 135 to 250m (average 160m). Strong tidal currents between the East China Sea and the Pacific Ocean developed in the study area may induce the transpotation of sediment particles to a shallower environment. This is demonstrated by the occurrences of this species in sediment deposited in depth shallower than inhabiting depth. The analyzed tests were not altered by long-time contact with bottom water because they preserve surface structures and a narrow range of oxygen isotopic composition. Shortly after G. inflata died and settled on sea bottom, the tests were commonly transported to the shallower environment by the upwelling, which may result from strong tidal currents and the topographic feature of the Ryukyu Island Arc
Renormalization group approach to multiple-arc random matrix models
We study critical and universal behaviors of unitary invariant non-gaussian
random matrix ensembles within the framework of the large-N renormalization
group. For a simple double-well model we find an unstable fixed point and a
stable inverse-gaussian fixed point. The former is identified as the critical
point of single/double-arc phase transition with a discontinuity of the third
derivative of the free energy. The latter signifies a novel universality of
large-N correlators other than the usual single arc type. This phase structure
is consistent with the universality classification of two-level correlators for
multiple-arc models by Ambjorn and Akemann. We also establish the stability of
the gaussian fixed point in the multi-coupling model.Comment: 11 pages, 1 figure, LaTeX + a4.sty, epsf.st
Cement generations and diagenetic history of the upper Ordovician Cliefden Caves Limestone Group of New South Wales, Australia
Diagenetic features of the upper Ordovician (Caradocian) Cliefden Caves Limestone Group (N. S. W., Australia) were studied by the cathodoluminescence (CL) method, and their relation with depositional environments was discussed. The Cliefden Caves Limestone Group was deposited on a shallow marine carbonate platform developed on a volcanic island. The limestone succession reveals intertidal-subtidal lithofacies and consists of the Fossil Hill, Belubula, and Vandon Limestones, in ascending order. The Fossil Hill Limestone mostly consists of bedded limestone rich in brachiopods and sedentary organisms. The Belubula Limestone is a typical Middle-Upper Ordovician peritidal succession with syn-depositional dolomite and silicified fossil grains. The Vandon Limestone consists of fossiliferous stratified limestone occasionally containing red brown argillaceous limestone beds.
The Cliefden Caves Limestone Group was subjected to various diagenetic processes. The investigation of CL is the best or only method to differentiate the diagenetic products. There are at least three cementation stages and a dissolution stage. The cements of the first stage are mainly dull fine-grained (10-30 µm) calcite crystals fringing inter- and intra-granular porosity, which typically indicate a marine phreatic environment. In some specimens of the Belubula Limestone, cement of the first generation exhibits meniscus fabrics suggesting precipitation in a marine vadose environment. The dissolution formed both molds of aragonitic skeletal grains and fabric-unrelated void spaces which can exceed several cm in diameter. Lack of the first generation cement within the dissolution voids indicates that the dissolution postdated the marine cementation. After the dissolution stage, the second cementation precipitated granular calcite crystals composed of non-luminescence, dull, and bright zones in the peripheral order. The relative thickness of non-luminescence and bright zones probably related with a redox condition during their diagenesis. The last generation of cements formed in a deep burial environment, is normally dull and filled almost all remained porosity. This diagenetic history fits to the change of depositional environment which may have been controlled by both of local and global environmental settings

The purpose of this article was to understand the psychological condition of the adult patient had received the steroid therapy for some diseases in hospital.A psychological factor of six patients was investigated by "Anxiety Cognition related to Sickness Questionnaire" and "General Health Questionnaire GHQ-12"in study 1.In study 2, three patients who had high anxiety cognition and low mental health degree was interviewed by Narrative Approach(NA).As the results of these studies, we presumed that the patients needed some supports according to them,because the patients had high anxiety and stress in hospital.And,it was suggested that the NA interview was effective method for assess patient's psychological side.And the rewriting the patient's story by NA interview could improve patient's mental health
Development research of pitching machine controlling variable ball using neural network
金沢大学工学部It is vey difficult to change simultaneously the pitching speeds and the course in the usual used pitching machines of the arm type and the two rollers type. In this study, the pitching machines which is able to pitch exactly a base ball into various courses and speeds using the three rollers controlled independently the number of rotations, is developed. In the pitching machine, the layered neural network system in which the learning data use each course and speeds as input data and number of rotation of each roller as output data is used. This machine is one of the intelligent sport machine. In this paper, the system and its machanism are described
Exact Beta Functions in the Vector Model and Renormalization Group Approach
The validity of the renormalization group approach for large is clarified
by using the vector model as an example. An exact difference equation is
obtained which relates free energies for neighboring values of . The
reparametrization freedom in field space provides infinitely many identities
which reduce the infinite dimensional coupling constant space to that of finite
dimensions. The effective beta functions give exact values for the fixed points
and the susceptibility exponents.Comment: 13 pages (no figures) in LaTeX, TIT/HEP-215, NUP-A-93-4, a few minor

On the Treatment of Rayons with Synthetic Resins by Means of an Improved Method. (XVII) The Special Core-Resin Treatment Prior to Dyeing with Some Functional Finish Which may be Followed by Mechanical One (III). Dyeing and Functional Finish After Peeling off the First Outer and Skin layer Resin
In continuation of the foregoing paper of this series (XVl) the present one deals with the
functional dyeing as well as the second resin finish intended for the outer layer upon the
fiber,which had been core-resin treated and then peeled off the unavailing first resin on the
skin and outer layers in order to give the place for the dye and the second resin.
1t was found that the fiber as treated above,properly choosing the dye and the second
resin, showed to have a good balance with reference to the properties in compressional
resilience, knot strength, and 1ight fastness of the dyeing. The present method in view is
considered to be advantageous in that the fiber can be core-resin treated in white state in
tow form (or in any other form also), so that it can be processed on the part of the maker
and be stocked, and then can be dyed at any stage before the end product on the part of
the spinner or finisher as required, say, in staple, yarn or fabric stat
