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.

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。

The acetone extracts from three samples of the hepatopancreas of the poisonous scallops obtained on the Okhotsk Coast of Hokkaido Island were fractionated into two parts, hexane soluble fraction (fraction H) and 85% aqueous ethanol soluble fraction (fraction ) by partition to two layers. The majortoxic components in the mouse assay of “diarrheic shellfish toxin” by intra-peritoneal injection were found to be free unsaturated fatty acids showed the following toxicity in MU per g, 18:1 n-9 35, 18:2 n-6 , 18: n- 167, 18:4 n- , 20:5 n- 167, and :6 n- , respectively. Toxicity of the fraction Hin MUper g was much lower than that of the fraction . However, the toxicity of the fraction H per 1 g of the hepatopancreas was about twice that of the fraction , since the fraction Hwas much more abundant than the fraction in the hepatopancreas. The method for the assay of the diarrhetic shellfish toxin must be reexamined by considering the toxic effect of the free unsaturated fatty acids.

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.
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.
) 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 possibility of attenuation of microseismic waves due to the presence of an upward folding of the ocean bottom into the liquid is discussed in this paper. The upward folding of the ocean bottom has been idealized by means of an irregularity in the form of a rectangle intruding into the liquid and the evaluation of the displacement component at any point of the solid medium has been carried out in two stages. First, the change in the incident mode of the surface wave due to the presence of the rectangular irregularity has been determined, and second, the subsequent change of the resulting displacement components due to the termination of the liquid layer and the step change in elevation of the solid medium at the continental margin has been discovered. Finally, numerical calculation has been made to determine the attenuation of the microseismic waves of different periods due to the presence of the rectangular irregularity at the ocean bottom.

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 weeks in 208 nonfamilial hypercholesterolemia patients (/ 161, 4/ 47). The baseline lipoprotein concentration and the intake of energy and lipids were not significantly different between subjects with / and those with 4/ 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 4/ 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 4/ by the Kruskal Wallis test (p=0.041). The presence of 4/ predicted the degree of cholesterol reduction following dietary therapy.

This paper is concerned with dynamics of the standard penetration test (SPT). The usefulness of mounting strain gages at two different stations along a driven rod is described, together with a workable procedure of analysis. The analysis procedure makes use of the traveling time between the two gage points and enables one to identify the particle velocity, the displacement and the stress at any station of the rod, as well as the energy actually transmitted from a hammer to the rod. Particular attention is called for the consequence of inevitable, small errors in strain data upon such identifications. A pertinent procedure of error-correction is proposed and its validity is substantiated against the performance of well instrumented SPTs performed by the authors.

The nanocrystalline soft-magnetic ribbon alloy with a width of 10 mm prepared through annealing amorphous ribbon alloy at 698 K had a saturation magnetization flux density of 1. T and a coercivity of 11. A m⁻¹. The nanohetero-amorphous microstructure consisted of α-Fe nanocrystals with an average size of nm and amorphous neighbor phases. The results of polarization curves and electrochemical impedance spectra obtained in 0.5 M Na₂SO₄ and 0.5 M NaCl solutions demonstrated the positive shift of the corrosion potentials, the decrease in the passive current density, the increase in the breakdown potentials and the increase in the polarization resistance for the nanocrystalline ribbon alloy, compared with its amorphous counterpart alloy. The corrosion performance was improved via annealing, which is thought to result from the enrichment of constituent in the surface oxide layer.

We investigated the local structure changes of nanocrystalline alloy prepared by arc melting with various annealing conditions by XAFS. It was found that individual structural changes occur around each element (Fe, Si, P, Cu) by several annealing steps. The as-spun sample shows amorphous like structure. The Fe and Si phase crystallize by annealing at first transition temperature (693 K). On the other hand the local structure around Cu and P atoms changed by two steps at 693 K and 823 K. In order to examine the structure more detail, the XANES comparison and the curve fitting method for EXAFS were performed. The Cu atoms were embedded in bcc Fe phase between the first and second transition temperatures and changes to fcc Cu phase over 823 K. It was suggested that α-Fe phase including the isolated Cu atoms can be easily crystallized and shows the high magnetic performance. [DOI: 10.1380/ejssnt.2012.651]
