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 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.

The high-power reconnection heating of spherical tokamak (ST) has been studied in the TS- experiment by use of axial merging of two STs. In this method, the merging/ magnetic reconnection transformed a part of magnetic energy of merging STs into their thermal energy within short reconnection time. Our present low-field merging (0.-0.5kG, R-0.2m) attained the maximum heating power of -10MW and increased the beta-values of STs by factor 2- transiently. The ion heating energy was found to increase inversely with the q-value (B_t component) of two STs. The most probable cause for this dependence is fast reconnection speed/ outflow speed due to large anomalous resistivity of current sheet in low-q state. After merging startup, decrease in beta was observed especially in low-q STs, indicating that the final beta value of ST increased with the q-value.

The association between apolipoprotein (Apo-) polymorphism and the response of plasma cholesterol to dietary therapy (cholesterol intake of less than 300mg/day) was investigated for about 8 weeks in 208 nonfamilial hypercholesterolemia patients (/ 161, / 47). The baseline lipoprotein concentration and the intake of energy and lipids were not significantly different between subjects with / and those with / phenotypes. After the dietary therapy plasma total cholesterol and low density lipoprotein cholesterol were significantly decreased in both phenotype groups (p<0.05). The patients with / had significantly smaller reductions of LDL-C than the patients with /. The changes of LDL-C showed a significant difference between the patients with / and / by the Kruskal Wallis test (p=0.041). The presence of / predicted the degree of cholesterol reduction following dietary therapy.

BCR-ABL1 International Scale（IS）測定はチロシンキナーゼ阻害剤で治療されている慢性骨髄性白血病（CML）患者の治療効果をモニターする上で重要な検査法である。稀ではあるが，BCR-ABL1 IS測定ができないCMLが存在することが知られている。本研究において，我々は，そのようなBCR-ABL1 IS測定のできないCML患者を経験し，分子生物学的な方法で，その原因を解明した。本例ではABL1遺伝子における切断点がa2エクソン内にあることが分かり，そのことがABL1のa2エクソンを欠いた

14a（a）キメラ遺伝子のmRNAのみの発現を誘導していた。a2エクソンは本邦における検査部でのIS測定において重要な要素であり，これが欠損することが測定不能の原因であった。このようなIS測定ができない稀なCML症例をさらに集積して，その分子構造を解明することが待たれる。

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, ) Ravenala-Strelitzia-Phenakospermum and c) Holiconia are recognised as suggested by some authors. For these groups sub-familial status is proposed.
. 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.
. 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.
) 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
) 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.

The leaning tower of Pisa is a famous historical structure, especially in the field of soil mechanics. In this paper, the historical development of the inclination is reconstructed considering that a ground failure took place after each of the three construction phases. Model tests (scale 1 : 130) were carried out in order to predict that the tower will fail definitely, i.. without any further disturbances, at an angle of inclination of 5.7°, which is dramatically close to the actual value of 5.5°. The estimated probability of failure rises very quickly with an increase in the angle of inclination. Conservation of the tower should be done therefore with utmost caution.

The performance of single pitch and multi pitch screw anchors during the application of installation torque is presented. An experimental testing program was conducted using five models of screw anchors with different geometry. The effect of the shape of the screw element, sand properties, and installation depth on the required installation torque value was examined. A theoretical model was developed from which the required installation torque value can be calculated in terms of the influencing factors. The required installation torque can be determined in terms of the ultimate uplift resistance calculated from any of the available theories. Based on the actual installation torque value measured in the field, the anticipated pullout capacity can be back calculated from the present theory. A comparison between theoretical and experimental results showed good agreement. Also, good agreement was observed when the present theoretical results were compared with the available field results reported in the literature.

Results of model loading tests on dense sand were reviewed to assess the variation in bearing capacity factors N_γ and N_q relative to the width of the foundation base. Consequently, it is confirmed that N_γ decreases non-linearly with increase in the width of foundation base and that N_q decreases more sharply than N_γ does as the width increase. It is also found that N_q decreases as the ratio of burried depth to the width increase. The cause of decrease in N_γ or N_q with increase in the width is regarded to be the rise of stress level which induces lowering of the angle of internal friction φ and volume reduction in the bearing sand by compression.

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>8. A new dimensionless index is proposed to quantify the internal stability of gap-graded soils.

Estriol antisera were raised and studied for the use in radioimmunoassay (RIA) of urinary estrogen as an aid of diagnosis of feto-placental function. Antisera to estriol-related six haptens, i.., estriol 16-glucuronide (-16-G), estriol 16-hemisuccinate (-16-succ), estriol 17-hemisuccinate (-17-succ), estriol 16, 17-dihemisuccinate (-16, 17-succ), estriol -carboxymethylether (--CME) and estriol -glucuronide (--G), were obtained by immunizing rabbits with the respective haptenbovine serum albumin (BSA) conjugate. Antiserum to -16-G-BSA reacted significantly with -16-G, C-17 conjugated estrogens and free estrogens. But it did not react with C- conjugated estrogens and other steroids. Similar properties were observed with antisera to -16-succ-BSA, -17-succ-BSA and -16, 17-succ-BSA, but their reactivities with C-16 or C-17 conjugated estrogens were slightly lower than that of anti--16-G-BSA serum. Among antisera which were raised against estriol linked to BSA via hemisuccinate varying in linking posirion, anti--16-succ-BSA serum highly reacted with -16-G, while anti--17-succ-BSA did with -17-G. Anti--16, 17-succ-BSA serum reacted with C-16 and C-17 conjugated estrogens to nearly the same extent. Antisera to both --CME-BSA and --G-BSA reacted with estrogens conjugated at C- position, but failed to react with C-16 or C-17 conjugated estrogens. The latter antiserum reacted more specifically with and -G than the former. Estrogen values in pregnancy urine samples estimated by the RIA by use of anti--16-G serum were not influenced by other components in urine, and showed a good correlation of y=0.81x-1.28, r=0.983 with those determined by the currently available colorimetric method with -kit.
