    The applicability of a method for predicting 'bearing capacity increase'in reinforced sandy ground was examined using tests performed under various test conditions. It was found that the present method predicted, with reasonable accuracy, the bearing capacity increase in sandy ground, reinforced with stiff reinforcement. This method may not be applicable for sandy ground reinforced with extensible reinforcement due to the unsuccessful formation of a semirigid zone under the footing. An investigation into the settlement of a footing on reinforced sandy ground, at ultimate footing load condition, suggested that the settlement of footing for reaching peak footing load may be correlated to the 'deep-footing'and the 'wide-slab'mechanisms. That is, the ultimate settlement ratio between reinforced and unreinforced model sandy ground, SRf, may be linearly correlated to 'BCRD'and 'BCRs', which represent 'deep-footing' and 'wide-slab'effects, respectively, on the ultimate bearing capacity increase in reinforced sandy ground.

    L'entree en Iran des armees britannique et sovietique s'est produite en aout 1941. Elle ebranla du coup le regime de la dynastie pahlavi qui etait au pouvoir depuis 16 ans, et mena le pays vers l'instabilite politique et le chaos social. La defaite de l'arme gouvernementale, qui etait le pivot du regime de Reza Shah, reduisit considerablement le controle du gouvernement central dans le pays. Cette situation politico-sociale confuse permit le developpement de differents mouvements politiques en Iran. C'est ainsi que le 16 aout 1942 le parti clandestin Komeley Jiyanewey Kurdistan (J-K) est ne a Mehabad, une ville au nord-ouest de l' Iran. Des sa formation, ce parti a su etendre sa sphere d'activite et, en une courte periode de temps, a fini par mettre sous son influence la ville et ses alentours. A la fin de la Seconde Guerre mondiale, en ete 1945, le J-K etait devenu une organisation representant le mouvement nationaliste kurde en Iran. C'est a ce moment-la qu'un autre parti politique, le Hizbi Dimokratiki Kurdistan (HDK), fonde par Qazi Mihemed a Mehabad aussi, devait remplacer le J-K. Des le
    22
    janvier 1946, le HDK proclama l'instauration de la≪Republique de Kurdistan≫. Cependant, les troupes sovietiques qui avaient pris sous leur protection la Republique evacuerent les terres iraniennes, en mai 1946. Six mois plus tard, sous la pression militaire du gouvernement central iranien, la republique s'ecroula. Deux theories tentent d'expliquer le passage du J-K au HDK. William Eagleton Jr., par exemple, affirme dans The Kurdish Republic of 1946 que le HDK a ete cree sur le conseil des autorites sovietiques. L'ex-secretaire general du Parti Democratique du Kurdistan d'Iran, 'Ebd el-Rehman Qasimlu maintient par contre que Qazi Mihemed a etabli le nouveau parti de sa propre initiative, eu regard a la situation politique de cette epoque-la. Il considere que la passage du J-K au HDK comme etant l'evolution d'un parti nationaliste clandestin en un parti democratique. En analysant ces deux theories et en se basant sur les autobiographies des personages qui se sont engages dans cet evenement, cette etude tentera d'examiner le principe directeur et les activites du J-K et de mieux comprendre les raisons pour lesquelles le J-K devait etre remplace par le HDK. La conclusion generale portera sur les differents objectifs politiques du J-K et du HDK. Le J-K visait l'elevation du niveau culturel du peuple tout en luttant contre le tribalisme, qui etait, selon lui, le probleme majeur de≪la nation kurde≫, et cela en ecartant toute idee de revolte militaire. Le J-K a aussi exclu de son cadre les elites sociales telles que les leaders des tribus et dirigeants religieux de peur qu'ils n'excercent une influence sur les membres du parti. L'automne de 1944 fut le debut d'une nouvelle ere pour le mouvement kurde. Alors que l'espoir de l'autodetermination augmentait parmi le peuple a mesure que s'approchait la fin de la guerre, la necessite de la force militaire a commence a se faire sentir dans le J-K. C'est pour cela que s'est produite au sein du parti une tendance a compter sur l'aide militaire des sovietiques et a recourir au leadership de Qazi Mihemed, qui avait une certaine influence meme sur les leaders tribaux. Mais cette tendance etait essentiellement incompatible avec la ligne fondamentale du J-K et, graduellement, a prive ce parti de sa raison d'etre. Ainsi, le HDK se substitua au J-K en tant que≪parti democratique≫visant a rallier d'abord les elites sociales sous sa banniere, en s'appuyant sur l'autorite personnelle de Qazi Mihemed.

    A new limit equilibrium analysis for assessing the stability of a reinforced embankment on soft clay against rotational undrained failure is presented. The analysis considers strain compatibility along the slip surface to deduce the tension mobilized in extensible reinforcement at collapse condition, and models strain softening of soils along the slip surface. The load extension responses of the reinforcement can be dependent on confinement by soils. Non-uniform increase in undrained cohesion during construction can be accounted for. The analysis yields a 'Safety Factor Curve' instead of a unique value for safety factor. A parametric study for illustrating the relevance of the proposed analysis is reported.

    It has been shown after mathematical and mechanical investigation that Limit Equilibrium Method (LEM) can be considered as a method to obtain the necessary condition of Slip Line Method (SLM), and that the solution can be obtained under the condition that Fs=1 and ∂Fs/∂θ=O, where Fs is the safety factor and θ is the inclination of the plane on which the safety factor is defined. Next, the generalized LEM (GLEM) is proposed, dealing with the following points : (1) Triangular or quadrangular blocks can be treated; (
    2
    ) Safety factors are defined also on interblock planes; and (
    3
    ) All types of plastic problems, slope stability, bearing capacity, and earth pressure are identically formulated. Two situations regarding treatment of the moment equilibrium condition are discussed. GLEM is applied to well-known problems. The results agree well with those obtained by theoretical methods. GLEM can be used to obtain the distribution of earth pressure or bearing capacity. GLEM, Iike ordinary LEM, is very effective for the practical problems, but GLEM is more theoretical and it can result in more accurate solutions.

    1. The chromosome numbers of 64 species have been studied on which 56 are investigated for the first time.
    2
    . Morphological, anatomical and cytological findings on the Musaceae in the broad sense are considered from a phylogenetical standpoint and three distinct groups:
    a) Musa-Ensete,
    b
    ) Ravenala-Strelitzia-Phenakospermum and c) Holiconia are recognised as suggested by some authors. For these groups sub-familial status is proposed.
    3
    . Lowiaceae have been studied for the first time cytologically and their chromosome morphology, distinct from that of any other group of Zingiberales, confirms their claim to familial status.
    4. Consideration of the conflicting theories proposed to account for the higher chromosome number in genera like Globba, Alpinia, and Phaemeria, etc. leads to rejection of Chakravorti's hypothesis of wholesale fragmentation of chromosomes and the acceptance of the opposed view of Raghavan and Venkatasubban and others.
    5. Holttum's transference of the genus Zingiber to the tribe Hedychieae has been given cytological support on the following points:
    a) the basic number in the genus Zingiber correlates with that of Kaempferia.
    b
    ) the new tribe Alpinieae (which is infact Zingibereae without Zingiber) have consistently 48 chromosomes in their somatic complements.
    6. It is suggested that the African representatives of Kaempferia should be given the status of genus; Cienkowskya on the following points:
    a) the difference in floral morphology
    b
    ) geographical separateness and
    c) the difference in the number and morphology of the chromosomes. By comparing the present and past findings, various lines of evolution of the chromosome complements within each group are discussed.
    7. The basic number 11 is considered to be probably the original one for the Zingiberales as a whole, being present in Ravenala which is the most primitive member in the order. From this secondary basic numbers have arisen through evolution.

    Objective: This study was conducted to determine whether to perform endovascular intervention or bypass surgery as a treatment option for critical limb ischemia (CLI) with lesions in the popliteal artery or below.Subjects and Methods: A total of 150 patients (164 limbs) with CLI underwent endovascular intervention or bypass surgery for lesions in the popliteal artery or below at our department between May 1995 and June 2011. Therapeutic outcomes were examined by surgical technique. An indication for endovascular intervention was established with the combination of (1) poor general condition, and (

    , respectively, diabetes in 36% and 55%, renal dysfunction in 29% and 58%, ischemic heart disease in 27% and 32%, and cerebrovascular disorder in 18% and 23%; renal dysfunction accounted for a significantly higher percentage in group
    E
    . As for early postoperative complications, subjects in group
    B
    experienced wound infections (6 patients), hemorrhage (
    2
    ), thrombosis (
    2
    ), pneumonia (1), and another complication (1), and those in group
    E
    experienced wound infections (1) and another complication (1). The hospital mortality rate was
    0
    .8% (1 patient) for group
    B
    and
    0
    % for group
    E
    . The
    3
    -year cumulative primary patency rate was 72% for group
    B
    and 54% for group
    E
    ; the rate was significantly higher for group
    B
    . The
    3
    -year secondary patency rate was
    82
    % for group
    B
    and 60% for group
    E
    . The
    3
    -year limb salvage rate was 86% for group
    B
    and
    82
    % for group
    E
    ; there was no significant difference between the two groups. The 5-year survival rate was 57% for group
    B
    and 42% for group
    E
    ; the survival rate was significantly lower for group
    E
    .Conclusion: For the study population of CLI patients with lesions in the popliteal artery or below, the patency rate was higher for the bypass group than for the endovascular intervention group, whereas there was no difference in the limb salvage rate. Based on the findings in prognosis for survival, the indication for endovascular intervention at our department is believed to be appropriate. (*English translation of Jpn J Vasc Surg 2013;

    (17), which are blocked for 24-hydroxylation by the methyl groups, were synthesized from 1α,
    -bismethoxymethoxypregn-5-ene-20Scarbaldehyde (6) by using the orthoester Claisen rearrangement for construction of the carbon skeleton of their side chains. These compounds (13 and 17) elicited a rise in serum calcium, but not in serum inorganic phosphorus in rats. In a bioassay for alkaline phosphatase, they were found to show much weaker activity than 1α-hydroxy vitamin
    D3
    (5).
