Effect of Cold-Rolling on Precipitation Phenomena in Sensitized Type 316L and 304L Austenitic Stainless Steels

引用

材料热处理学报 2004年第5期25卷 217-222页

作者： H.Tsubakino A.Yamamoto T.Yamada L.Liu M.Terasawa S.Nakahigashi H.harada GraduateSchoolofEngineering UniversityofHyogoHimejiHyogoJapan GraduateStudent UniversityofHyogoHimejiHyogoJapan JapanPowerEngineeringandInspectionCo. YokohamaKanagawaJapan Koyo-SeikoCo.Ltd. KashiwaraOsakaJapan

Precipitation phenomena in Type 316L and 304L stainless steels were studied mainly by transmission electron microscopic (TEM) observations after cold-rolling ranging from 0% (as solution annealed) to 80% reduction in thickness, and then by sensitization treatment. Precipitates were identified by electron diffraction analysis and EDS analysis. Precipitates observed in sensitized 316L stainless steel were sigma and chi phases, whereas carbide and sigma were observed in sensitized 304L stainless steel. Recrystallized grains were formed in 30% cold-rolled and sensitized 304L. However, the tendency toward recrystallization in sensitized 316L was much lower than in 304L. Precipitation of sigma and chi phases was accelerated by cold-rolling and they were observed at grain boundaries in lower cold-rolling; they were also seen, in grain interiors in higher cold-rolling. Higher deformation induced partially recrystallization combined with precipitation, resulting in the formation of heterogeneous microstructures.

Intraductal papillary neoplasm of the bile duct in liver cirrhosis with hepatocellular carcinoma

World Journal of Gastroenterology 2011年第14期17卷 1923-1926页

A case of intraductal papillary neoplasm of the bile duct (IPNB) arising in a patient with hepatitis B-related liver cirrhosis with hepatocellular carcinoma (HCC) is reported. A 76-year-old man was admitted to our hospital with recurrent HCC. Laboratory data showed that levels of carcinoembryonic antigen and carbohydrate antigen 19-9 were elevated. He died of progressive hepatic failure. At autopsy,in addition to HCCs,an intraductal papillary proliferation of malignant cholangiocytes with fibrovascular cores was found in the dilated large bile ducts in the left lobe,and this papillary carcinoma was associated with an invasive mucinous carcinoma (invasive IPNB). Interestingly,extensive intraductal spread of the cholangiocarcinoma was found from the reactive bile ductular level to the interlobular bile ducts and septal bile ducts and to the large bile ducts in the left lobe. Neural cell adhesion molecule,a hepatic progenitor cell marker,was detected in IPNB cells. It seems possible in this case that hepatic progenitor cells located in reactive bile ductules in liver cirrhosis may have been responsible for the development of the cholangiocarcinoma and HCC,and that the former could have spread in the intrahepatic bile ducts and eventually formed grossly visible IPNB.

State of Art of Ants (Hymenoptera: Formicidae) at Caxiuanã, Melgaco, Pará, Brazil

引用

Advances in Entomology 2016年第3期4卷 115-132页

作者： Ana Yoshi harada Coordination of Zoology Museu Paraense Emílio Goeldi Belem Brazil

The ants are one of the mega diverse insets found in all terrestrial environments, and occur in great diversity, richness and abundance, acting at all trophic levels. The present study was conducted to verify the knowledge of ant fauna at Caxiuanã National forest. All available ant literature and some collection in Caxiuanã were compiled and analyzed in EXCEL program. Caxiuanã is one Brazilian Amazonia forest that has good biological conservation. A total of 197 species belonging to 52 genera of the nine subfamilies are present in Caxiuanã. Many studies need to be done in this place to understand the ant community pattern to give base for other studies and proposal for use, management and conservation of this interesting Amazonia place.

Influence of substrate surface roughness on light scattering of TiO2 optical thin films

引用

Chinese Optics Letters 2013年第13期11卷 83-86页

作者： Toshinori harada Hiroshi Murotani Shigeharu Matumoto Hiromitu Honda Course of Electro Photo Optics Graduate School of Engineering Tokai University Japan Sincron Co. Ltd. Japan

Optical thin films are used in many optical elements; however, light scattering can be problematic. We investigate the effect of substrate surface roughness on the light scattering of optical thin films. The substrates are classified according to their surface roughness, from fine to very rough, and coated with a single TiO2 layer or a SiO2/TiO2 multilayer. The light scattering intensity increases as the substrate roughness increases. Scanning electron microscopy reveals that the number of nodules formed in the optical thin films increases with the substrate roughness, which affects the light scattering properties.

Locally advanced pancreatic cancer located in the head or un-cinate process(i.e.,uncus)often invades the confluence of the superior mesenteric vein(SMV),portal vein(PV),and splenic vein(SV)[1,2].Additionally,chronic pancreatitis easily occludes drainage flow via the SV[3].These pancreatic diseases force sur-geons to perform en bloc resection of the *** ligation of the remnant SV without venous resection results in sinistral por-tal hypertension(PH)(i.e.,left-sided PH),gastrointestinal bleeding,splenic congestion,and hypersplenism over the long term[1,2].

Regio- and Substrate-Specific Oxidative Metabolism of Terpinolene by Cytochrome P450 Monooxygenases in <i>Cupressus lusitanica</i>Cultured Cells

引用

American Journal of Plant Sciences 2012年第2期3卷 268-275页

作者： Takako harada Eriko harada Ryoko Sakamoto Tatsuya Ashitani Koki Fujita Department of Environment Faculty of Agriculture Yamagata University Tsuruoka Japan. Department of Sustainable Bioresources Science Faculty of Agriculture Kyushu University Fukuoka Japan

Many of monoterpenes produced in plants contribute to defenses against herbivores, insects and microorganisms. Among those compounds, β-thujaplicin formed in Cupressaceae plants has a unique conjugated seven-membered ring and some useful biological activities, e.g. fungicide, repellent, insecticide and so on. The biosynthesis pathway of β-thujaplicin has not yet been revealed;we have been trying to uncover it using Cupressus lusitanica cultured cells as a model. In our previous study, terpinolene was identified as a potential β-thujaplicin intermediate at the branching point to terpenoids. In this article, terpinolene metabolism in C. lusitanica cultured cells was investigated, and it was shown that the microsomal fraction from cells oxidized terpinolene into the hydroxylated compound, 5-isopropylidene-2-met-hylcyclohex-2-enol (IME). Then, IME was further oxidized by microsomal fraction to the epoxidized compound, 1,6-epoxy-4(8)-p-menthen-2-ol (EMO). These were the only two products detected from the microsomal reactions, respecttively. Moreover, microsomal reactions with monoterpenes other than terpinolene produced nothing detectable. These results show that the enzymes of these reactions had strict substrate specificity and regio-selectivity. Experiments on kinetics and with specific inhibitors confirmed that these reactions were caused by cytochrome P450 monooxygenases, respectively. These results support our hypothesis that terpinolene is a putative intermediate of β-thujaplicin biosynthesis and show that IME and EMO are also putative intermediates.

Study on Digitization of TCM Diagnosis Applied Extraction Method of Blood Vessel

引用

Journal of Signal and Information Processing 2011年第4期2卷 301-307页

作者： Cong Wu Koichi harada 不详

This paper presents a study on digitization of Traditional Chinese Medicine diagnosis. The research consists of two aspects: a) algorithms for blood vessels extraction in sclera-conjunctiva images, which can be applied in syndrome differentiation by observing human eyes (named Ocular Diagnostic in Traditional Chinese Medicine);b) digitization of extracted vessels. First, sclera-conjunctiva region is isolated by optimal threshold segmentation and mathematical operation;Scanning and edge detection methods are used to gain the edge of the blood vessels. Moreover, the edge feature parameters are gained, which can be used to reconstruct the blood vessels. Experimental results show that blood vessels information can be obtained fast and accurately for the further TCM diagnosis by artificial system.
