Open Journal of Polymer Chemistry 2020年第1期10卷 1-20页

作者： Tomoharu miyanaga Naofumi Naga Graduate School of Engineering and Science Shibaura Institute of Technology Tokyo Japan Department of Applied Chemistry College of Engineering Shibaura Institute of Technology Tokyo Japan

Organic-inorganic hybrid network polymers have been synthesized by addition reaction of a thiol-functionalized random type silsesquioxane (SQ109) and alkyl diacrylate or diisocyanate compounds. Thiol-ene reaction of SQ109 and 1,4-butanediol diacrylate (BDA) successfully yield porous polymer in toluene initiated by azobis(isobutyronitrile) (AIBN) at 60°C. Morphology of the porous polymers was composed by connected globules, and the diameter of the globules decreased with increasing in the monomer concentration of the reaction system. By contrast, the reaction with 1,6-hexanediol diacrylate or 1,5-hexadiene yielded homogeneous clear gels. Thermal analyses of SQ109-BDA porous polymers indicated that thermal degradation of ester groups of BDA in the polymer network occurred at around 300°C. The porous polymer was also obtained by the reaction using a photo-initiator (Irugacure184) at room temperature, and showed higher Young’s modulus than the corresponding porous polymer obtained with the reaction with AIBN due to the small size of the globules. Young’s modulus

Intussusception is a common cause of mechanical bowel obstruction among children,with older children being more likely to have a pathological lead *** neoplasms are rare and small intestinal lipomas are even less *** we describe a case of a 7-year-old boy with ileoileal intussusception,with an ileal lipoma as the pathological lead *** tomography was useful pre-operatively for revealing intussusception due to lipoma as the pathologic lead point.

Pollination efficiency of hairy footed flower bee Anthophora plumipes for greenhouse strawberry was evaluated in a small greenhouse located in Shimane University, Matsue, Japan (lat. 35°29', long. 133°27' and elevation 170 m). Twenty five female and six male bees were released in a greenhouse on April 15, 2014. Red clay soil blocks were provided as the nesting materials. Two hundred and fifty pots of strawberry (Fragaria annanasa) were allocated for the following three treatments: 1) no supplementary pollination (control), 2) hand pollination, and 3) bee pollination. Both male and female bees effectively foraged flowers throughout the day. Rate of fertilized seed by the bee pollination was significantly greater than no supplementary pollination (control) and similar to that in the hand pollinated flowers. Quality of the fruits (evaluated based on the shape and deformity) was also improved by the bee pollination. A. plumipes effectively pollinated strawberry flowers in the greenhouse and could be developed as an alternative pollinator for this crop.

Reviewed are the present status and future prospects of the laser fusionresearch at the ILE Osaka. The Gekko XII and Peta Watt laser system have been operated forinvestigating the implosion hydrodynamics, fast ignition, and the relativistic laser plasmainteractions and so on. In particular, the fast ignition experiments with cone shell target havebeen in progress as the UK and US-Japan collaboration programs. In the experiments, the implodedhigh density plasmas are heated by irradiating 500 J level peta-watt laser pulse. The thermalneutron yield is found to increase by three orders of magnitude by injecting the peta-watt laserinto the cone shell target. The Rayleigh-Taylor instability experiment results are also reviewed isthis paper.

日本的原油储藏岩洞建在三个地方。为防止这些贮油洞中的油和天然气泄漏,使用了隔水系统。其中一个贮油洞位于有裂缝和渗透力很强的花岗岩中,预计会有大量地下水流入贮油洞。因此为减少渗流量,采用了无压粘土灌浆。在实施这种方法之前,进行了室内和现场试验,来证实粘土的隔水机理和粘土灌浆的效果。在这些试验的基础上,对上述贮油洞室成功地应用了这一方法。本文概要叙述粘土灌浆及其效果。

BACKGROUND Capsule endoscopy and balloon-assisted enteroscopy(BAE) enable visualization of rare small bowel conditions such as small intestinal malignant ***,details of the endoscopic characteristics of small intestinal malignant tumors are still *** To elucidate the endoscopic characteristics of small intestinal malignant *** From March 2005 to February 2017,1329 BAE procedures were performed at Keio University Hospital. Of these procedures,malignant tumors were classified into three groups,Group 1: epithelial tumors including primary small intestinal cancer,metastatic small intestinal cancer,and direct small intestinal invasion by an adjacent organ cancer; Group 2: small intestinal malignant lymphoma; and Group 3,small intestinal gastrointestinal stromal tumors. We systematically collected clinical and endoscopic data from patients' medical records to determine the endoscopic characteristics for each *** The number of patients in each group was 16(Group 1),23(Group 2),and 6(Group 3),and the percentage of solitary tumors was 100%,43.5%,and 100%,respectively(P < 0.001). Patients' clinical background parameters including age,symptoms,and laboratory data were not significantly different between the groups. Seventy-five percent of epithelial tumors(Group 1) were located in the upper small intestine(duodenum and ileum),and approximately 70% of gastrointestinal stromal tumors(Group 3) were located in the jejunum. Solitary protruding or mass-type tumors were not seen in malignant lymphoma(Group2)(P < 0.001). Stenosis was seen more often in Group 1,(68.8%,27.3%,and 0%;Group 1,2,and 3,respectively; P = 0.004). Enlarged white villi inside and/or surrounding the tumor were seen in 12.5%,54.5%,and 0% in Group 1,2,and 3,respectively(P = 0.001).CONCLUSION The differential diagnosis of small intestinal malignant tumors could be tentatively made based on BAE findings.
