Yttrium samples were levitated in an electrostatic levitator and their radiation intensities at their melting temperature were measured by spectrometers over a wide wavelength range. By comparing the measured intensities with those of a blackbody, spectral hemispherical emissivity values were calculated. The total hemispherical emissivity of yttrium at its melting temperature was calculated by integrating the spectral hemispherical emissivity and was found to be .32. The constant pressure heat capacity was also calculated using time-temperature data and was found to be 37. J·mol-1·K-1 at 1795 K.

When mixed with methanol containing a catalytic amount of sulfuric acid and kept at 10°C for 10 h, benzoylacetone () gave two products methoxylated on the side of the acetyl group (viz., , -dimethoxy-1-phenyl-1-butanone (AK) and -methoxy-1-phenyl-2-buten-1-one ()) but no products methoxylated on the side of the benzoyl group (4, 4-dimethoxy-4-phenyl-2-butanone (BK) and 4-methoxy-4-phenyl--buten-2-one (')) or products methoxylated on both carbonyls. Furthermore, did not undergo acid-catalyzed methanolysis under our conditions. The reason why acetal formation of the acetyl carbonyl occurs more easily than that of the benzoyl carbonyl, and the relationship of AK and , which is not an intermediate in the formation of AK from even though AK can be formed from it, are discussed.

[1] The purpose of this reserch is to make clear what type of design can give good effects to win the high readership score. At the begining I had to know what factors decide the readership score, and how to change the quality of the desing into numerical value. I have used the method of multi-dimentional analysis with the help of a computer, and got the estimation formula, with kinds of factors, as follows ; A^^〜=+C+D+K++bF+cG. A^^〜=estimated values of the readership score. 1) , C, D, K : these four factors are given as category values (so we call them); each factor is classified into several categories. =week day, classified into categories. C=pages of a newspaper, which are characterized by the kinds of articles, news, and the other reading matters, classified into categories. D=kinds of goods and trades of the advertizement, classified into 14 catedories. K=constants, given to each 13 surveys. 2) , F, G : these factors are given as numerical values. G=area of advertizement, measured by the unit of column in the whole page length, being classified into 6 kinds of area (2., ., , , 10, 15) and 15 column means a whole page, about 2,000cm^2. , F are the marks obtained in the design of advertizements. =sum of the marks obtained in each design element on the advertizement. F=the marks obtained on the whole effect of the design. ) a, , c : coefficients Using the above formula with the category values and the coefficients, we can obtain the naked design effect from the actual value A of readership score: +bF=A-(+C+D+K+cG). In this research, I used 1,829 data of readership score from 1960 to 1968, being obtained by 13 survevs, spring and autumn twice a year. The sample of size each survey was ,541, 2,251, or 200 in the other 11 surveys. Multiple correlation coefficient between the estimated value A^^〜 and the actual value A is .951. The table 2^* shows the contribution indexes of each factor by kinds of expression-(1) Range : the absolute difference between the maximum and the minimum category values, (2) Standard deviations of the category values, () Partial correlation coefficient : the relationship between the actual values A and each factors. *see the table 2 in the thesis in Japanese. [2] The important point was in the determination of the values of , F. is the sum of the marks obtained in each design element, classified into four kinds : =_1+_2+_+_4. design elements [table] _1, _2, _, _4, these values have the grades, as , 1, 2, , 4 and is given to the design that has no attractive effect or no applicable element. And obtain the marks of to 9 grades as the sum of them. The values of F have also grades, to 4. The principles to determine the values of , F are as follows : a) The marks obtained of , F must be the relative values among the each survey, and at the same time, they must have constancy within the same survey-the same elements of design must win the same marks obtained. ) They must be determined as to win the highest multiple correlation coefficient, when they are put into the estimation formula. c) They must be reasonable. In order to justify them, we must carry many researches on the actual condition. The frequency of accurence of each grade of , F values, as the table -4, and - in the thesis in Japanese.

The acoustic emission (

) technique was used to develop a method for the objective evaluation of the crispness of porous foods. The crispness of six types of commercial porous foods was changed by controlling their moisture contents at six levels by varying the humidity (i.

e

., dry, , 43, 56, 68, and % relative humidity) of the storage environment at 25 °C. As the crispness of a sample with high water activity (a_w) was expected to deteriorate, the physicochemical, mechanical, and acoustic characteristics of a_w-controlled food samples were evaluated. The a_w had no influence on the shape and porous structure of the foods. However, the number of force peaks in the uniaxial compression test appeared to be related to their a_w. Moreover, the breaking characteristics of a sample at different a_w values changed depending on the porous food type classified according to the degree of starch gelatinization. Among the characteristics, the number of events and count corresponded well with the a_w of the porous food. Therefore, for an objective evaluation of the crispness of porous foods, the events and count, which are highly sensitive, can be suitable indicators, rather than the number of force peaks.

  Ubiquitous access to large quantities of information content is one of the main benefits anticipated from the emerging global interconnection of computer networks. One of several major factors in achieving this objective is the cost and performance of the distributed storage systems which will act as the repositories for the information. This article presents an overview of the architecture, major components and requirements for storage systems which can support distributed storage intensive applications.

Ocean waves are not regular, as are assumed in the ordinary theory of rolling, and accordingy the max angle of roll deduced therefrom is not directly applicable in practical case. In this paper, the waves are not assumed to be regular, but only one wave, which passes the ship in one swing, is considered as sine form, and the limiting angle of swing possible in that ease is found. The angle of swing is generally given by
θ=K-∞Σn=1θn cos nkt.
But a large swing can safely be represented by
θ=K- κt…(1)
This fact, valid both for apparent and absolute rollings, can be mathematically proved in both cases(Appendix)and also is observed from the record of actual rolling on sea as Fig.1
Assuming the form(1), only the swing, whose final amplitude is not less than the initial one, need to be taken into consideration for the present problem, then this condition gives the relation that σ must be less than unity. The final amplitude of swing θ_f is given by
θ_f = [+(1-σ²)] sinσπ/2/√4σ²(-1)²+(1-σ²)²tan²σπ/2…(2)
The maximum value of θ_f for various σ is the desired limiting angle, which occurs, practically σ= 1/. Consequently θ_fmax occurs at σ=1 for >1, and at σ= 1/ for >1, the results being as follows,
θ_fmax=1/√(-1)² +(2a_ee/π)² for <1 or T_w<T_s
T=T_w.
θ_fmax=2+(-1)/a_ee²(-1)cosπ/ for >1 or T_w>T_s
T=T_s
θ_fmax=π/ for =1 or T_w=T_s
T=T_w=T_s.…()
The effective extinction coef. in these expression is to be determined by the following equations
=a+√2b_γΘw/ [(1-)²+(2a_ee/π)²] for <1.
=a+2b_γΘw/a_ee²(-1)cosπ/ for >1.
=a+b_γΘw/2a_eπ for =1.…(4)
For the absolute rolling, the limiting angles are given by multiplying to the results (), and the , by taking instead of γΘHw in (4).
These results are calculated and given, in Fig. 2.
The same method can also be applied for the swing on waves affectedby wind, in which the, new. variable θ=θ-φ is to be used instead of θ and the_fmax is given by(), then the limitting angle is equal to θ_fmax plus φ.
These treatment is based on the assumption of isochronous stability curve, but the above results can also be applied to the non-isochronous case. The approximate θ'_fmax for non-isochronous ship can be got by taking the same area below the stability curve in both cases.

This is the successive report to the previous one. Here, three main items are picked up; various conditions of aggregates, . concrete mix, broken stone concrete mix, both plain and air-entraining. (1) Conditions of aggregates. The whole mix table is first systematized in absolute volume mix. The other methods are derived from it by culculation according to the conditions of the aggregate, which is somewhat different from normal one. Statistical and empirical data on specific weight, percentage of absolute volume, standard and field measuring are given. The ground of the culculation will thus become clear. (2) . concrete mix. The mix table is shown in the previous report. The way of modifing the Standard-mix and of getting . mix are explained. The JASS method of modification is available in this case. We lessen °/wt of water and decrease sand in plastic mix. Stiff concrete of , 10cm slump is obtained directly by experiment, for we have no such mix in the Standard-mix. () Broken stone concrete. a. Consistency of concrete is different according to the grading of the broken stone even within the allowable grading limits. To get concrete of better consistency coarser grading is advantageous. . Water should be added 〜12°/wt to the Standard-mix. This is different from JASS and it is proved to be harmless to the strength. c. .S., . concrete can be got following JASS, lesseing water °/wt from plain concrete in plastic mix. Stiff mix was made through experiment. The mix table is shown to the end.

Contact of rough surfaces can be replaced by that between a rough surface and a rigid flat one, so that the methods of the rd report can be reapplied here. In this report, the factors of surface asperities (for example, slope and height of surface asperities in contact) were synthesized, and formulae for practical use on the elastic and the plastic deformation of rough surfaces in contact when the directions of surface asperities were parallel to each other were suggested. This report revealed that the variance of slope of surface asperities of surface asperities in contact is σ_θ1²+ , where σ_θ1², are variances of slope of projections respectively. As a result, the relations between the elastic and the plastic deformations δ_E, δ_S yielded by the existence of surface asperities and the normal load are as follows. δ^^-

Prostaglandin -receptor subtypes, EP₁, EP₂, , and EP₄, are present in the kidney. The aim of this study was to elucidate the anti-nephritic effect of an EP₄-receptor agonist on an experimental nephritic model. Mice were injected i.v. with anti-glomerulus antiserum to induce nephritis. Nephritic glomeruli generated more prostaglandin (2.6 and . ng) and less cyclic AMP than normal glomeruli (11 and 26 pmol). The production of cyclic AMP in nephritic glomeruli increased 67% in response to 1-329, an EP₄ agonist, at 10⁻
