    Five species of lecideoid lichens belonging to three genera are reported as new to the flora of the Prince Olav Coast and the Soya Coast, Enderby Land, East Antarctica; they are Carbonea capsulata (DODGE & BAKER) HALE, Lecidea andersonii R. FILSON, Lecidea cancriformis DODGE & BAKER, Lecidea soyaensis M. INOUE and Lecidella siplei (DODGE & BAKER) M. INOUE. All are endemic to Antarctica. An examination was made of the collections from the region, which were collected mainly by the author under the project of the 27th Japanese Antarctic Research Expedition (JARE-27,during January 1986 and February 1987). The type and authentic specimens of possibly related species have been restudied. Lecidea soyaensis M. INOUE is new to science and Lecidella siplei (DODGE & BAKER) M. INOUE is proposed as a new combination. Taxonomic and chemical data as well as a key to the known taxa are provided

    Feasibility of the Inoue single-branched stent-graft implantation for thoracic aortic aneurysm or dissection involving the left subclavian artery: Short- to medium-term results in 17 patients

    ObjectiveThis study assessed the short- to medium-term clinical results of the Inoue single-branched stent graft for repair of thoracic aortic aneurysms or dissections involving the left subclavian artery.MethodsA retrospective review of experiences at two institutions was performed. We analyzed the data of consecutive 17 patients with thoracic aortic aneurysms or dissections who underwent endovascular repairs with the Inoue single-branched stent graft between July 1999 and April 2004. Complete baseline and follow-up data were available on all patients. The mean age was 71 ± 9 years, and 13 of the patients (76%) were men. Eight patients (47%) were considered unfit for open surgery because of advanced age or the presence of comorbid diseases.ResultsThe stent grafts were successfully delivered and deployed in all 17 patients. Periprocedural major complications, defined as those that caused any persistent disorder, occurred in one patient who developed spinal ischemia. A postoperative computed tomographic scan revealed three attachment site endoleaks; two endoleaks were from the proximal attachment sites and one endoleak was from the distal attachment site. The mean follow-up period was 26 months (range, 7 to 65 months). Two deaths occurred in the follow-up period from cerebral bleeding and pneumonia, both considered unrelated to the stent grafting. Two patients with attachment site endoleaks needed secondary stent-grafting; one patient required the implantation of a straight stent-graft in the distal attachment site and the other, the implantation of a double-branched stent-graft. Another patient with attachment site endoleak was considered very high-risk for open surgery or secondary stent grafting and did not undergo secondary intervention. The aneurysmal sac size of the patient has been stable for 28 months. The branched section of the stent graft was patent in all patients in the follow-up period.ConclusionThe results demonstrate the feasibility of the Inoue single-branched stent graft for thoracic aortic aneurysms or dissections involving the left subclavian artery

    The Hobby of Electronic Circuit Engineering

    No full text
    This website (originally created in Japanese and translated into English using translation software) by a Japanese systems engineer, Seiichi Inoue, provides an extensive overview of electronic circuit engineering. Topics covered include: Basic knowledge of Electronic parts, Basic knowledge of Engineering Instruments, an Introduction of Engineering Method, and the Assembly Process. A variety of electronic circuits and their uses are provided, as well as a separate section on PIC electronic circuits. The language may be difficult to follow at times given the translation, but still a gem of a site for anyone wanting to build some circuits! Keep in mind that in some sections, the author notes that he is "describing while studying, there seems to be mistakes in the contents. Do at your own risk." For some further browsing, he includes sections on his other interests, such as 3D photography, java programming, CAD, Japanese customs and the Japanese language

    Water partitioning in the Earth's mantle

    We have conducted H2O partitioning experiments between wadsleyite and ringwoodite and between ringwoodite and perovskite at 1673 K and 1873 K, respectively. These experiments were performed in order to constrain the relative distribution of H2O in the upper mantle, the mantle transition zone, and the lower mantle. We successfully synthesized coexisting mineral assemblages of wadsleyite-ringwoodite and ringwoodite-perovskite that were large enough to measure the H2O contents by secondary ion mass spectrometry (SIMS). Combining our previous H2O partitioning data (Chen et al., 2002) with the present results, the determined water partitioning between olivine, wadsleyite, ringwoodite, and perovskite under H2O-rich fluid saturated conditions are 6:30:15:1, respectively. Because the maximum H2O storage capacity in wadsleyite is ∼3.3 wt% (e.g. Inoue et al., 1995), the possible maximum H2O storage capacity in the olivine high pressure polymorphs are as follows: ∼0.7 wt% in olivine (upper mantle just above 410 km depth), ∼3.3 wt% in wadsleyite (410-520 km depth), ∼1.7 wt% in ringwoodite (520-660 km depth), and ∼0.1 wt% in perovskite (lower mantle). If we assume ∼0.2 wt% of the H2O content in wadsleyite in the mantle transition zone estimated by recent electrical conductivity measurements (e.g. Dai and Karato, 2009), the estimated H2O contents throughout the mantle are as follows; ∼0.04 wt% in olivine (upper mantle just above 410 km depth), ∼0.2 wt% in wadsleyite (410-520 km depth), ∼0.1 wt% in ringwoodite (520-660 km depth) and ∼0.007 wt% in perovskite (lower mantle). Thus, the mantle transition zone should contain a large water reservoir in the Earth's mantle compared to the upper mantle and the lower mantle

    <Article>The Revolts of Shezei 社賊 and Tuzei 土賊 during the Late Ming and Early Qing Period

    No full text
    個人情報保護のため削除部分あり本稿は、明末清初の時期、広東珠江右岸デルタ地帯で展開された社賊、土賊の反乱の性格究明を直接の課題としている。社賊、土賊の反乱は、ともにに対する抵抗運動としての性格をもっており、なかでも社賊の変は郷村在住のに重大な打撃を与え、郷村をその内部から崩壊させた。この社賊の変は、従来、奴僕の身分解放運動として扱われてきたが、検討の結果、それが奴僕・佃僕を主体とする私的隷属民及びその他の郷村の下層民衆から構成されるとともに、次のような複合的な性格を保持していたことが明らかになった。第一に、主家の身分支配の打破を志向した奴僕・佃僕を主体とする私的隷属民の闘争の側面であり、第二に、利益を独占して、郷村の再生産機能の維持に努めない「富室」に敵対する側面である。更に第三点としては、地主・佃僕間の生産関係上の矛盾の激発としての抗租の側面が摘出された。以上の諸側面を内包しつつ、社賊はと対立・抗争を繰り広げたのである。This article aims to make clear the characters of the revolts of Shezei and Tuzei which took place around the right part of the Zhujiang 珠江 Delta during the Late Ming and Early Qing period. Both the revolts of Shezei and Tuzei had the character of a resistance against the xiangshen 郷紳 or gentries. Especially, the revolt of Shezei seriously damaged the gentries and destroyed the villages. Though the revolt of Shezei has been considered as a liberation movement of the nupu 奴僕 (bond servants), the examination clarified two points. 1) The rebellious people were composed not only of the nupu (private subordinates), but also of the dianpu 佃僕 (field servants who were private subordinates similar to the nupu) and also of the other lower class of inhabitants in the villages. 2) The character of this revolt was the composite of three aspects as follows. A) The struggle for the status liberation against their masters by those such as nupu and dianpu. B) Hostility against the rich families which neglected the reproduction and monopolized the profits in the villages. C) The struggle against the rent as a conflict between the dianpu and the landowners. So, the revolt of Shezei countered the xiangshen, involving the various classes and comprising the manifold factors, which have not been clarified
