The possibility of attenuation of microseismic waves due to the presence of an upward folding of the ocean bottom into the liquid is discussed in this paper. The upward folding of the ocean bottom has been idealized by means of an irregularity in the form of a rectangle intruding into the liquid and the evaluation of the displacement component at any point of the solid medium has been carried out in two stages. First, the change in the incident mode of the surface wave due to the presence of the rectangular irregularity has been determined, and second, the subsequent change of the resulting displacement components due to the termination of the liquid layer and the step change in elevation of the solid medium at the continental margin has been discovered. Finally, numerical calculation has been made to determine the attenuation of the microseismic waves of different periods due to the presence of the rectangular irregularity at the ocean bottom.

The effect of composition and controlled thermomechanical process parameters on the mechanical properties of HSLA steels is modelled using the Widrow-Hoff's concept of training a neural net with feed-forward topology by applying Rumelhart's back propagation type algorithm for supervised learning, using a Petri like net structure. The data used are from laboratory experiments as well as from the published literature. The results from the neural network are found to be consistent and in good agreement with the experimented results.

An unsupervised learning technique and an associative memory have been used for encoding weights by a special type of Petri network named Petri neural net for modelling the influence of alloying elements on the final property of the high strength low alloy steel. The combined effects of alloying elements for different strengthening mechanisms is predicted when weights and threshold values are chosen on the basis of metallurgical understanding. The technique is found to be effective to create an associative memory of input-output relations in unknown data sets so that the same can be subsequently be used as a predictive tool.

Primarily from the point of view of improvement of yield strength due to additions of niobium, titanium and boron in HSLA steels, the experimental steels are divided into five classes. The data are then supplied for learning a Self Organising Map (Kohonen network). It is found that the network with six neurons possesses better capacity of prediction with unknown data. Another effort of clustering the steels according to its major strength contributing mechanisms is also made. But the capacity of the network to cluster unknown data is found to be rather poor and has failed to follow from the metallurgical principles. To avoid this limitation, Learning Vector Quantisation method is adopted to impart a certain amount of supervision in the learning process and it is found that the training pattern of the network attains a good convergence thereby leading to a good predictive ability.

A boron treated copper bearing HSLA steel containing austenite formers like manganese and nickel, somewhat lower in amount than that in HSLA 100 variety of steel is chosen for the study. The role of thermomechanical processing on the microstructure and mechanical properties of the above steel has been investigated. Differential scanning calorimetric study is carried out for understanding the precipitation behaviour of copper in HSLA steel under the influence of boron. The microstructure of the experimental steel is found to consist of laths of martensites and bainite. MA constituents of ribbon like morphology are observed at the lath boundaries. Higher strength properties of the steel are attributed to the presence of finely distributed precipitates of copper and microalloy carbides.

Horizontal plate anchors are widely used in civil engineering constructions to resist vertical pulling loads. The available theoretical model suggested by Vesic to estimate the breakout resistance of plate anchors is in significant error, particularly for dense sandy soils. A theoretical model assuming a curved surface of failure through the surrounding soil, to evaluate the ultimate breakout resistance of horizontal plate anchors, has been proposed. It successfully brings out the concept of characteristics relative depth beyond which the breakout factor reaches a constant final value. It is capable of predicting breakout factors for wide range of values of angle of shearing resistance of sand.

Nine isoquinoline alkaloids belonging to the protoberberine, proaporphine and bisbenzyl-isoquinoline series were isolated from Caryomene olivascens (Menispermaceae). Four compounds are new : (-)--norlimacine (), (-)-caryolivine (), (+)-1, -dehydro--norlimacusine () and N-formylstepharine (). The last one is the first N-formyl derivative to be reported in the proaporphine group. Its biogenetic origin is discussed. Structures were established on the basis of 360 MHz (FT) nuclear magnetic resonance measurements and also by chemical correlation in the case of .

Simultaneous measurements of the total geomagnetic field intensity by the same type of the proton precession magnetometers at two stations in NW Turkey have been taken cooperatively by a research group since December 1970. Up to the end of July 1971 mainly three probable local magnetic changes were observed. It was seen that after a decrease in the local field at a magnetic station (Erdek) a few earthquakes occured at either nearly N or S of that station, and after an increase in the local field an earthquake took place nearly W of the same station. In this paper the data and some results of the first part of observations are given.

Thirty-six patients (19 males, 17 females: atypical schizophrenia; , typical schizophrenia; , depression; 11, neurosis and other psychiatric disorders; ) were operated on according to orbitoventromedial undercutting by Hirose. In all cases, the Rorschach test was carried out and daily behaviors were studied. Thirty-one scales of the test were subjected to multivariate analysis whereas the behaviors were evaluated according to the following criteria, i.., A: recovered or symptom free, : markedly improved, C: moderately improved, D: slightly improved and : not improved. The following results were obtained.
1) The evaluation of behaviors is as follows. A: 12 cases, : , C: , D: , : none.
) It was found that scores of F+106% and R+106% scales were significantly higher after the operation than before; that correlation coefficients between the scores before and after the operation were considerably high.
) Factor analysis followed by varimax rotation was carried out. Six factors were extracted, i.., (F1) sensitivity to emotional stimuli, (F) ego-strength, (F) obsessional rigidity, (F) reaction time, (F5) anxiety and tension and (F) empathy. It was revealed that F was high in atypical schizophrenia, depression and neurosis, and that F and F were significantly different in terms of the factor scores among the four groups A, , C and D; F was highest in A, and lowest in D regardless of whether it was before or after the operation. F showed high scores in both A and C, and low in D.
) Multiple discriminant analysis was applied to the data of the Rorschach test before the operation, by classifying 36 subjects into the four groups A, , C and D. As a result, high rates of correct diagnosis were obtained, i.., 100% for A, 78% for , 56% for C and 100% for D. When the groups C and D were combined into one group (C+D) the highest percentage (100%) was seen in A, followed by (%) and C+D group (87%). When the groups A and were combined into one group (A+), the percentages of correct diagnosis were % for A+, and % for C+D.
In conclusion, it can be said that scales of the Rorschach test have been proved to be valid for predicting mental and physical states after the orbito-ventromedial undercutting.

A sample of [

3H

] tobrarnycin (5, 000 Ci/Mole) has been synthetized and incubated with
the bacterial ribosome and its subunits. The results obtained show that this antibiotic has
two types of binding sites. The primary one is probably responsible for the inhibition of
protein synthesis whereas the secondary one is probably related to the misreading and reading
tiirough of the messenger RNA.
