    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.

    This study aimed to determine the prevalence of fecal carriage of extended spectrum β-lactamase (ESBL) and/or plasmidic AmpC β-lactamase (pAmpC) producing Escherichia coli among dogs (n=428) in Turkey. Polymerase chain reaction (PCR) and sequencing were used to characterize genes encoding β-lactamase and plasmid mediated quinolone resistance (PMQR). Antimicrobial susceptibility testing and PCRs for virulence genes and phylogenetic groups were also performed. Cefotaxime resistant

    Six new cembranoids sarcophytol P (3), R (4), S (
    5
    ), K (8),
    F
    (11), and T (13) were isolated from the soft coral Sarcophyton glaucum. Sarcophytol P (3) was shown to be the 20-hydroxy derivative of the major component sarcophytol A (
    1
    ), and afforded the cyclization product
    6
    in CHCl_3 at room temperature, in a same way as in
    1
    . Sarcophytols R (4) and S (

    ) were correlated to
    1
    , by conversion of its
    7
    R,8R and
    7
    S,8S epoxide derivatives. Sarcophytol K(8) was a 13, 14-dihydroxycembranoid having a

    ,3Z-isomers of

    (11,

    ), N (15,
    1

    1
    (
    1
    Z,3
    E
    ), which affords trans-fused bicyclo[
    9
    .3.0]tetradecene systems. The
    1
    E
    ,3Z-isomer 13 gave the same cyclization product 18, as in the reaction of
    1
    , even though it is isomeric at C-
    1
    ,3. The
    1
    Z,3Z isomer 15 gave 19, in consequence of the reversed geometry at C-3 of 15. The
    1
    E
    ,3
    E
    -isomer (11) gave the bicyclic product
    22
    , having an antipodal fusion as compared with 19. This was confirmed by PCC oxidation of 19 and
    22
    , giving enantiomeric ketones 23 and 24 respectively. The
    1
    (14)-epoxide 26 was shown to be the immediate precursor of
    22
    , and acounted for the inversion of the geometry at C-
    1
    of the cyclization product. Compound 26 is isomeric with the epoxide 17 derived from
    1
    . The epoxide 17 is the postulated precursor in the conversion of 13 to 18. It is noteworthy that the mode of antipodal fusion of the cyclopentane rings, in 18 and
    22
    , was controlled by the chirality of the epoxy rings. The C-14 hydroxyl group participates in the transannular cyclization, but was found not to be the requisite functional group for the reaction. Similar treatment of cembrene C (30), the parent hydrocarbon of
    1
    , also reacted in CHCl_3 giving the bicyclic product 32.

    ] 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
    7
    kinds of factors, as follows ; A^^〜=
    B
    +C+D+K+aE+bF+cG. A^^〜=estimated values of the readership score.

    )
    B
    , C, D, K : these four factors are given as category values (so we call them); each factor is classified into several categories.
    B
    =week day, classified into
    7
    categories. C=pages of a newspaper, which are characterized by the kinds of articles, news, and the other reading matters, classified into
    22
    categories. D=kinds of goods and trades of the advertizement, classified into 14 catedories. K=constants, given to each 13 surveys. 2)
    E
    ,
    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.

    E

    F
    are the marks obtained in the design of advertizements.
    E
    =sum of the marks obtained in each design element on the advertizement.
    F
    =the marks obtained on the whole effect of the design. 3) a,
    b
    , 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: aE+bF=A-(
    B
    +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 3,541, 2,251, or 200 in the other 11 surveys. Multiple correlation coefficient between the estimated value A^^〜 and the actual value A is 0.951. The table 2^* shows the contribution indexes of each factor by 3 kinds of expression-(
    1
    ) Range : the absolute difference between the maximum and the minimum category values, (2) Standard deviations of the category values, (3) 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

    have also

    F
    are as follows : a) The marks obtained of
    E
    ,
    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.
    b
    ) 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

    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.
