The modulns of longitudinal elasticity and their temperature dependence in commercial aluminum cast alloys were measured in the temperature range from room temperature (20°C) to 250°C by the resonant frequency method. The results obtained are as follows:
The modulus of longitudinal elasticity tended to decrease weakly and linearly (the tangent of its decrease, m = (-

) × 10²kg/
cm²
/°C) with the rise of temperature. Within the range of the experiments, aluminum cast alloys were divided into
3
groups, the lst group materials having large moduli of elasticity

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 ability of Climacodon septentrionalis to immobilize and kill a mycophagous nematode (Aphelenchoides sp.) in vitro is described for the first time. Two isolates produced droplets (20–45 μm in diameter) that formed at the apices of tall, stalked, and branching secretory cells (700–
1
,500 μm tall). On
2
% modified malt extract agar, nematodes became enveloped in the droplets, which restricted their ability to move and resulted in complete immobilization and death within several hours of contact. The rate of decomposition of the nematodes varied considerably, with most individuals persisting for weeks whereas others were degraded within several days and appeared to be colonized by dense hyphal growth. This study provides the first documentation of a non-agaricoid fungus producing secretory cells that are able to immobilize nematodes.

The world is in the midst of a huge fundamental shift in fibre supply, demand balances, and policy changes. Governments around the world are introducing policy changes which influence the supply demand balance as the politicians' thoughts are uttered. Government agencies and their bureaucrats are imposing changes on industry even before the legislation is passed by the government in question.
This ad hoc change process will continue for a time to come until the countries in question show a tough-mindedness with regard to their land use policies. Policies affecting forest areas such as protection areas, Native land claims, the protection of biodiversity and a true goal of sustainable development ; which addresses the combined issues of cultural, environmental, social and economic matters.
Eventually all of these difficult issues will reach essential closure. Then there will be great new opportunities for investment to meet the growing demand for forest products ; leading to a strengthening competitive position in the more traditional producing areas such as Canada.

One method currently being considered for the disposal of high level radio-active waste is burial in the seabed. When a hot object is buried in soil, the temperature of the soil adjacent to the object is raised and there is transient heat flow away from the object. The rise in the temperature of the soil causes excess pore pressures to be generated and transient pore water diffusion also takes place. A finite element formulation of the coupled heat flow and consolidation problem is presented. The computer implementation of this formulation is found to compare favourably with analytical solutions based on the same physical principles.

3
∼10% as determined by our rapid ^{3H

. The mechanism of synchronization by BH-AC
was considered S phase prolongation by the inhibition of DNA synthesis.
Remission induction therapy by DCMP or DBMP at a proper time carefully determined by LI of marrow blasts according to our new protocol gave complete remission rate of 85

%, i.e

of the 7
firstly treated cases and that of 57.1

From our above-mentioned results, S phase partial synchronization by BH-AC by the use of our rapid autoradiography is considered to be a useful tool for treatment of leukemia.

Although there have been numerous articles concerning the anatomy of the atrioventricular valve in man, only a few publications have recorded the relationship between the chordae tendineae and the papillary muscles. The purpose of this paper is to study the relationship among the shape and size of the atrioventricular valve, the chordae tendineae and the papillary muscles. 50 subjects, as listed in Table
1
, were analyzed by the Taniya-Hashimoto Method.
The results obtained were as follows:
1
) The right atrioventricular valve was classified into two types: 33 cases (66%) of three irregularly shaped cusps, i.
e
. type I, and 17 cases (34%) of four or five cusps, i.
e
. type II.
2
) The average circumference of the right atrioventricular orifice (ostium atrioventriculare dextrum) was 11.
96
cm (
9
.63.15.06cm) in type I and 12.19cm (
9
.52.15.
22
cm) in type H. There existed no significant difference in the circumference of the atrioventricular orifice between type I and II.
3
) The average length of the cusp-fundus (the length of the fixed margin of the cusp) was as follows:

The length or width of the cusp in type I was similar to that in type II.

The chordae tendineae from the anterior papillarymuscles were attached to the anterior and posterior cusps and those from the postlateral and postmedial muscles were attached to the posterior and septal cusps. The chordae tendineae from the postseptal muscles were linked only to the septal cusp and those from the septal muscles were connected to the septal and anterior cusps.

It is shown that the observed value of the
AC
loss of a cylindrical BSCCO bulk superconductor with the diameter of
9
.
6
mm, carrying the
AC
transport current with the frequency of 60Hz, deviates noticeably from the theoretical values estimated from the critical state model. It is clarified that this deviation results from the fact that the internal distribution of flux density,
B
(r), is quite different from that predicted by the critical state model, when the
AC
transport current with the frequency, f, of 60Hz is applied to the sample with a large diameter, R, and with a low n-value. This conclusion is based on the numerically simulated results of
B
(r) obtained by solving the Maxwell equations using the observed J_c=J_c(
B
) and
E

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.

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.

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.
