Effect of pressure on the magnetic, transport, and thermal-transport properties of the electron-doped manganite CaMn1−x_{1-x}Sbx_{x}O3_{3}

We have demonstrated the effect of hydrostatic pressure on magnetic and transport properties, and thermal transport properties in electron-doped manganites CaMn$_{1-x}$Sb$_{x}$O$_{3}$. The substitution of Sb$^{5+}$ ion for Mn $^{4+}$site of the parent matrix causes one-electron doping with the chemical formula CaMn$^{4+}_{1-2x}$Mn$^{3+}_{x}$Sb$^{5+}_{x}$O$_{3}$ accompanied by a monotonous increase in unit cell volume as a function of $x$. Upon increasing the doping level of Sb, the magnitudes of both electrical resistivity and negative Seebeck coefficient are suppressed at high temperatures, indicating the electron doping. Anomalous diamagnetic behaviors at $x=0.05$ and 0.08 are clearly observed in field cooled dc magnetization. The effect of hydrostatic pressure on dc magnetization is in contrast to the chemical pressure effect due to Sb doping. The dynamical effect of ac magnetic susceptibility measurement points to the formation of the magnetically frustrated clusters such as FM clusters embedded in canted AFM matrix.Comment: 12 pages,11 figures, 3 table

Study of developing a teaching program for a voter education from an elementary school to a high school Based on developing a tentative lesson plan of an elementary social studies in order to teach about vote

　本研究は，市民社会に寄与し得る有権者の育成を目指し，児童・生徒の発達段階に応じた有権者教育のあり方 を追究して，小学校から高等学校までの12 年間を一貫する原理にもとづいた有権者教育プログラム開発のため の原理と方法を解明しようとするものである。そのために，第一に，子どもたちの政治に対する認識調査を行い， 子どもたちが政治的な概念についてどのような認識を持っており，それを教育によってどの程度まで変容させる ことができるかを明らかにした。そして，第二に，その調査の結果と従来の政治教育研究の成果をふまえて，有 権者教育のための小中高一貫カリキュラム・フレームワークを提示した。それに基づいて，第三に，具体的な単 元開発を行った。単元は，「選挙」，「議会」，「税金」という政治学の基本的概念をテーマとして取り上げて開発 したが，本稿では「選挙」概念をテーマとして開発した小学校社会科の単元を紹介する

Skeletal Metastasis in Renal Cell Carcinoma: Photon Deficiency on Bone Scintigraphy

Bone scintigraphy with 99mTc-labeled phosphorous compound is an excellent technique for the detection of bone metastasis. Bone metastases are usually visualized as multiple hot spots on bone scintigraphy. However, photon deficiency in the metastatic lesion on bone scintigrams is reported in few cases with malignancy. In this study, we have evaluated the photopenic bone metastasis from renal cell carcinoma by the radiographic and computed tomographic examinations. Photon deficient metastatic lesions were seen on bone scintigraphy in 5 patients with renal cell carcinoma. All of the photon deficient lesions were osteolytic on bone radiography and computed tomography. The pure photon deficient lesions not associated with surrounding hot margins were seen on the thoracic vertebrae and rib and the ones with surrounding hot margins were seen on the sternum, pelvis and femur. This difference may be due to the differences in the growth rate of the tumor and reactive hyperemia and new bone formation in the metastatic lesions

BULGE-FORMING GALAXIES with AN EXTENDED ROTATING DISK at z ∼ 2

We present 0".2-resolution Atacama Large Millimeter/submillimeter Array observations at 870 um for 25 Halpha-seleced star-forming galaxies (SFGs) around the main-sequence at z=2.2-2.5. We detect significant 870 um continuum emission in 16 (64%) of these SFGs. The high-resolution maps reveal that the dust emission is mostly radiated from a single region close to the galaxy center. Exploiting the visibility data taken over a wide $uv$ distance range, we measure the half-light radii of the rest-frame far-infrared emission for the best sample of 12 massive galaxies with logM*>11. We find nine galaxies to be associated with extremely compact dust emission with R_{1/2,870um}<1.5 kpc, which is more than a factor of 2 smaller than their rest-optical sizes, R_{1/2,1.6um}=3.2 kpc, and is comparable with optical sizes of massive quiescent galaxies at similar redshifts. As they have an exponential disk with Sersic index of n=1.2 in the rest-optical, they are likely to be in the transition phase from extended disks to compact spheroids. Given their high star formation rate surface densities within the central 1 kpc of Sigma SFR1kpc=40 Msol/yr/kpc^2, the intense circumnuclear starbursts can rapidly build up a central bulge with Sigma M*1kpc>1e10 Msol/kpc^2 in several hundred Myr, i.e. by z~2. Moreover, ionized gas kinematics reveal that they are rotation-supported with an angular momentum as large as that of typical SFGs at z=1-3. Our results suggest bulges are commonly formed in extended rotating disks by internal processes, not involving major mergers.Comment: 11 pages, 6 figures, 2 tables, accepted for publication in Ap

Hyperoxemia and excess oxygen use in early acute respiratory distress syndrome : Insights from the LUNG SAFE study

Publisher Copyright: © 2020 The Author(s). Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background: Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods: In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence of hyperoxemia (PaO2 > 100 mmHg) on day 1, sustained (i.e., present on day 1 and day 2) hyperoxemia, or excessive oxygen use (FIO2 ≥ 0.60 during hyperoxemia). Results: Of 2005 patients that met the inclusion criteria, 131 (6.5%) were hypoxemic (PaO2 < 55 mmHg), 607 (30%) had hyperoxemia on day 1, and 250 (12%) had sustained hyperoxemia. Excess FIO2 use occurred in 400 (66%) out of 607 patients with hyperoxemia. Excess FIO2 use decreased from day 1 to day 2 of ARDS, with most hyperoxemic patients on day 2 receiving relatively low FIO2. Multivariate analyses found no independent relationship between day 1 hyperoxemia, sustained hyperoxemia, or excess FIO2 use and adverse clinical outcomes. Mortality was 42% in patients with excess FIO2 use, compared to 39% in a propensity-matched sample of normoxemic (PaO2 55-100 mmHg) patients (P = 0.47). Conclusions: Hyperoxemia and excess oxygen use are both prevalent in early ARDS but are most often non-sustained. No relationship was found between hyperoxemia or excessive oxygen use and patient outcome in this cohort.
