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 = (-2.--.) × 10²kg/cm²/°C) with the rise of temperature. Within the range of the experiments, aluminum cast alloys were divided into groups, the lst group materials having large moduli of elasticity at room temperature (i. ., = (.15-.25) × 10⁵kg/cm²) were 2A-T, A-F, A-F, A-T, -F, -T, A-F, A-T, etc., the 2nd group materials having intermediate moduli (i. ., = (.85-.98) × 10⁵kg/cm²) were C-F, C-T5, C-T, D-F, D-T, A-F, etc. and the rd group materials showing considerably smaller moduli (i. ., = (.58-.65) × 10⁵kg/cm²) were 1A-F, 1A-T, 2A-F, etc. However, there were some differences between the moduli in this experiments and the moduli in the other data books, and these were considered due to the difference of the measurement principles and of hypotheses or assumptions involved in these principles, so it is suggested that the moduli of elasticity should be reported with indication of the measuring method.

The phase diagrams of the Ni-Mo- and Ni-W- ternary systems in the region of less than 50mol% were constructed by thermodynamic calculation, based on the data obtained by thermodynamic measurement of the related materials. We found three ternary eutectic points and three or two ternary peritecto-eutectic points as follows:
:L (1365K, 71.5mol%Ni-.mol%Mo-.5mol%)=(Ni)++
:L (1355K, 62.5mol%Ni-2.5mol%Mo-30.5mol%)=++
:L (1445K, 42.mol%Ni-30.mol%Mo-10.mol%)=(Ni)+NiMo+
P₁:L (1812K, 34.mol%Ni-42.mol%Mo-.mol%)+MoB=+
P₂:L (1633K, 42.mol%Ni-40.mol%Mo-17.mol%)+Mo=+
:L (1812K, 53.5mol%Ni-33.mol%Mo-12.mol%)+Mo=NiMo+
:L (1622K, 51.mol%Ni-31.mol%W-17.mol%)=(Ni)+W+
:L (1260K, 71.mol%Ni-.mol%W-.mol%)=(Ni)++
:L (1291K, 65.mol%Ni-.mol%W-29.mol%)=++
P₁:L (2115K, 23.mol%Ni-43.1mol%W-33.1mol%)+WB=+
P₂:L (1657K, 48.mol%Ni-33.1mol%W-18.mol%)+=W+
The calculated phase diagrams are expected to be useful for the development of new Ni-based heat-, corrosion- or wear-resistance alloys.

Stress wave theory is applied to open-ended pipe piles to clarify the effects of soil plug on the behaviour of piles during driving and static loading. Measured field data and various numerical models are reviewed ; methods are presented to calculate wave propagation in both the pile and the soil plug ; modelling is presented which takes into account the interaction between the soil plug and the pile ; also presented is simplified method to estimate the loadsettlement relation of the pipe pile in static loading. By correlating observed and calculated values in two analytical cases, the authors demonstrate that incorporation of the soil plug (modelled as a series of masses and springs) is required to correctly predict pile behaviour during driving and static loading.

This study was performed to clarify which factors affected damage to tame-ike (small embankment dams for irrigation) in Hokudan Town as a result of the January 17, 1995 Hyogoken-Nambu earthquake. Factors were assumed to be : Location (.g., Distance to Epicenter, etc.), Structure (.g., Angle to Nearest Fault, Embankment Volume, etc.), Soil Properties of Embankment, Geology of Dam Site and History (Era of Construction, Repaired, etc.). Multivariate statistical analyses were performed for documentary data (damaged : 181, undamaged : 328). Ordinary statistical analyses were conducted for the data investigated in situ for soil properties of the embankment. The results show that the factors causing damage to dam are : (1) Nearest Fault (Nojima, Mizukoshi and D2), (2) Distance to Nearest Fault (less than 500 m), () Distance to Epicenter (approximately to 14 km, which almost agrees with the location of seismic intensity JMA), () Elevation of Dam Site (higher than 100 m), (5) Embankment Volume (the greater the volume the more damage was caused), () Direction of Dam Axis (normal or diagonal to the epicenter or to nearest the fault), () Plan View of Dam Axis ( or axes), () Surface Geology of Dam Site (non-cohesive soil type ground), () Era of Construction (prior to 1891) and (10) Soil Properties of Embankment (sand, not silty sand or gravel, penetration resistance that is 10% smaller than the undamaged dams).

The natural remanent magnetization (NRM) of three Apollo 11 lunar materials, i. . a crystalline rock and two kinds of microbreccia, is examined in detail with special attention to the possible effect of viscous magnetization acquirable in the terrestrial magnetic field.
The intensity of stable NRM (I_n), the critical -demagnetization field (H*) which represents the upper limit for keeping approximate invariance of NRM direction, and the effective demagnetization field () which reduces the intesity of NRM to (1/) of the initial value are determined as follows; (a) I_n=.×10-

The intense and extremely stable NRM of the strongly impacted lunar microbreccia may suggest that a strong impact of lunar materials can cause an acquisition of a particularly stable remanent magnetization even in a very weak magnetic field.
A certain portion of metallic irons in the lunar materials are very fine particles of several hundreds of Ångström in mean diameter. These particles behave almost superpara-magnetically. Saturated viscous remanent magnetization acquired in the geomagnetic field being denoted by ΔI_v, the ratio of 44 to the stable remanence I_n is determined to be

This paper provides a comprehensive survey of the numerical methods related to geotechnical problems, most of which were reported in papers appearing in Soils and Foundations. The reason why most of the reviewed papers are concentrated in Soils and Foundations is that if we were to include papers appearing in other journals in the field of geotechnical engineering, closely related to numerical methods, .g., Computers and Geotechnics, Int. J. Numer. Anal. Meth. Geomech., etc., we would have to deal with almost all the papers in those journals. Firstly, we present a description of the current status of the numerical methods, and then give a brief review of the literature covering several topics in geotechnical applications. The scope of the review is limited, and thus, the authors do not profess to cover the entire range of literature.

Male moths of the podborer, Matsumuraeses falcana (WALSHINGHM) whose larvae damage soybean crops were attracted with a 1 : 1 mixture of ()--dodecenyl acetate (-12 : ) and (, )-, 10-dodecadienyl acetate (10-12 : ) in field tests. The attractant activity was significantly increased when a third component, (, Z)-, -dodecadienyl acetate (Z-12 : ), was added to the 2-component blend, though Z-12 : attracted no males by itself. One of the best formulations was a rubber septum impregnated with 167 μg of each of these three components, which attracted ca. 1.5 times more males than the septum impregnated with 250 μg of each of -12 : and 10-12 : , and ca. 5 times more males than 10 live virgin female moths. Z-12 : evoked the typical precopulatory behavior by male moths at the ca. 50-fold dose level of the 1 : 1 mixture of -12 and 10-12 : , though neither of these two components showed any sex-stimulative activity by itself.

The mechanism of wave-induced instability in a permeable seabed have been studied for more than two decades. The distinction between shear failure and liquefaction, however, has not been clearly defined. This paper presents a fundamental study on the differences in two failure modes for a fully saturated seabed of both finite and infinite thickness. The wave-induced effective stresses and pore pressure, obtained from an analytical solution of Biot's pore-elastic consolidation theory, were employed to examine the failure modes under a two-dimensional plane strain condition. A case study is presented to examine the failure modes with respect to several parameters, such as excess pore pressure, seepage flow, seepage force, failure areas and stress path in the seabed. The conclusions obtained from this study were as follows ; (1) the thickness of a permeable seabed affects the pore pressure and effective stress response to ocean waves and the failure mode of the seabed, (2) either a liquefaction or shear failure, or both, occur in the seabed, even in the saturated seabed, () the Mohr-Coulomb's failure criterion, when combined with elastic stresses, can not be employed to estimate the liquefaction failure in the seabed, () the liquefaction can be evaluated by a criterion in terms of the excess pore pressure, (5) The liquefied zone in the seabed is significantly different from the shear failure zone. The shape beneath the seabed surface for the former is almost identical to the contour where the upward seepage flow is concentrated.

The filtration compatibility of soil-geotextile systems has been assessed experimentally in the laboratory with the gradient-ratio test. A nonwoven geotextile was used against a variety of model soils that were prepared from glass beads. They exhibited a range of fines content, in both gap-graded and broadly-graded size distributions. Filter blinding and clogging, if it happens, occurs within hours of initiating unidirectional flow. The zone of soil above the geotextile that is influenced is relatively thin. In gap-graded soils, the movement of fine particles appears to occur at a conditioh of D₈₅/D₁₅>. A new dimensionless index is proposed to quantify the internal stability of gap-graded soils.

Among the rivers damaged by the earthquake, two most severely damaged along the Yodo-gawa River are described. In the left levee, the settlement exceeded 2 m for a length of 1. km, with a maximum settlement of m. Sand boils were observed extensively on the ground surface near the damaged dikes. Holocene sandy soil with an SPT N-value of 10 or less existed in the upper part of the subsoil profile. These facts indicate that liquefaction of the soil was the major cause of the embankment damage. The cyclic stress ratio required to cause liquefaction was .30 as determined from cyclic triaxial tests on undisturbed samples.

Recently, Etiella behrii has been identified as a pod borer of soybean in Indonesia. This species had been presumably confused with

E

. zinckenella due to their similarity in external characters. We, therefore, compared the characteristics and sex pheromone between the two Etiella species. They could be accurately discriminated based on some external characters at both larval and adult stages, without examination of their genitalia. Duration of developmental stage of the insects reared on an artificial diet was days longer in

E

. behrii than in

E

. zinckenella at 25°C. Premating period was days longer in

E

. behrii than in

E

. zinckenella. Other biological data concerning mating and oviposition were similar between the two species. The sex pheromone of

E

. behrii was found to be a mixture of ()--dodecenyl acetate (-12:), (Z)-11-tetradecenyl acetate (Z11-14: ), dodecyl acetate (12:), and ()-11-tetradecenyl acetate (11-14:). Z11-14: and 11-14: are the common components in the two species. -12 and 12 in

E

. behrii, and 14: and Z-14: in

E

. zinckenella could be key components in reproductive isolation between the two species. Moreover, the optimum dose of the mixture for capturing

E

. behrii males was much smaller than that for

E

. zinckenella males.

The Gujarat earthquake in India occurred in January, 2001, and caused significant damage in the province of Gujarat. The Japanese Geotechnical Society sent a small reconnaissance team to the damaged region after the quake. The present text presents the report from this activity. The major attention of the team was focused on geotechnical aspects of the damage which were related to earthfill dams and harbor land fills. It was found that a significant portion of damage was concentrated in fills resting on soft natural soils. Swedish weight soundings which were conducted at two places demonstrated the existence of such a soft subsoil. From this, it was concluded that amplification of earthquake shaking as well as the permanent deformation in the soft foundation soil induced such kinds of damage as subsidence, cracking, and lateral spreading in overlying artificial fills. For the better seismic resistance of those affected fills during future earthquakes, the improvement of soft subsoil seems essential.

The boundary element method expanded in frequency domains is presented to analyze the dynamic interaction between an embedded flexible rectangular foundation and soil with consideration of the obliquely incident waves. Numerical results describing the influence of the flexibility of the foundation on the dynamic responses of the foundation due to obliquely incident waves indicate that the flexibility of actual foundations can diminish the reduction of translation responses and increase the rotational responses in the high frequency range. These phenomena are more conspicuous as the embedment ratio is larger and the value of the wave velocity ratio of the soil and the foundation approaches to unity. When the high frequency components of the input ground motion are important and the basement has higher flexibility (for example ₂v_s/₁v_s >.), the analysis method which considers the basement as a rigid foundation may lead to unsafety estimations and the estimation of the flexibility of the foundation is necessary as analysing the effective input motion with consideration of the incident waves.

The Tsukuba Challenge is a competition, in which autonomous mobile robots run on a route set on a public road under a real environment. Their task includes not only simple running but also finding multiple specific persons at the same time. This study proposes a method that would realize person searching. While many person-searching algorithms use a laser sensor and a camera in combination, our method only uses an omnidirectional camera. The search target is detected using a convolutional neural network (CNN) that performs a classification of the search target. Training a CNN requires a great amount of data for which pseudo images created by composition are used. Our method is implemented in an autonomous mobile robot, and its performance has been verified in the Tsukuba Challenge 2017.
