The Japanese Islands have grown through the formation of igneous rocks and accretionary prism caused by subduction of oceanic plates. However, the timing of the initiation of the subduction is not well defined. The South Kitakami Belt (SKB) in NE Japan is the best field to solve this problem. Here, basement igneous rocks are covered by successions of Ordovician to Early Cretaceous beds (450-100 Ma). We obtained LA-ICP-MS U-Pb zircon ages from the following localities. Along the Yakushigawa-Valley section in the northeastern part of the SKB, we examined the ages of (1) trondhjemite of the Kagura Complex of basement igneous rocks, (2) felsic tuff of the Koguro Formation conformably covering the Kagura Complex, and (3) Yakushigawa Formation covering the Koguro Formation and lying under the Silurian Odagoe Formation. In the Ohasama area in the northwestern part of the SKB, we examined the age of (4) Nameirizawa Formation, which probably lies below the Silurian Orikabetoge Formation. Moreover, we examined the ages of four samples from the Hikami Granite body in the central part of the SKB. The ages of trondhjemite (08331-5: 466±6 Ma) of the Kagura Complex and felsic tuff (08331-4b: 457±10 Ma) of the Koguro Formation indicate that the subduction of an oceanic plate had already started at 466 Ma, and that the Koguro Formation is the oldest age-known formation of the SKB. The tuffaceous sandstone of the Yakushigawa Formation (08331-3) has detrital zircons with the youngest age cluster of around 425 Ma, and is probably a Silurian formation. The tuffaceous sandstone of the Nameirizawa Formation (08331-9) has detrital zircons with the youngest age cluster of around 430 Ma. The formation is probably a Silurian formation and is correlated with the Yakushigawa Formation. Precise ages of around 412 Ma were obtained from the Hikamiyama body of the Hikami Granitic Rocks (08330-1,-3,-4), clearly suggesting that at least some parts of the body are not pre-Silurian basement.

A 41-year-old woman who had been given a diagnosis of aplastic anemia 14 years before was admitted because of recurrence of the disease. Despite therapy, the anemia progressed gradually. The patient refused blood product transfusions for religious reasons. Angina pectoris-like chest pain without ischemic changes on electrocardiograms appeared at a hemoglobin concentration (Hb) of 1.6 g/dl. The patient died of heart failure at Hb 1.5 g/dl. Autopsy showed enlargement of the heart, fatty changes in the myocardium and liver due to chronic hypoxia, and no changes in coronary arteries.

Objective Acute-onset diffuse interstitial lung disease (AoDILD) in patients with rheumatoid arthritis (RA) has been a serious concern, especially for those under treatment with biological agents which may affect the presentation and outcome of AoDILD, including Pneumocystis pneumonia (PCP). Therefore, we conducted a retrospective, multi-center study of AoDILD in RA patients receiving biological agents. Methods Patients who developed AoDILD while receiving biological agents (infliximab, etanercept, adalimumab and tocilizumab) were enrolled in the study. Definite PCP was defined as patients who showed either P. jirovecii organisms in their respiratory samples by microscopic examination, or positive tests for both P. jirovicii DNA-PCR with respiratory samples and an elevated serum 1,3-β-D-glucan level above the cut-off value. Probable PCP was defined as either a positive test for P. jirovicii PCR or an elevated serum β-D-glucan level. Chest HRCT findings were evaluated and scored by two board-certified radiologists. Results The final diagnoses for 26 patients examined were definite PCP for 13 patients, probable PCP for 11, and methotrexate-associated pneumonitis in 2 patients. Definite and probable PCP cases were clinically indistinguishable. Generalized, diffuse ground-glass opacity (GGO) is the characteristic HRCT finding in patients with definite or probable PCP, which was different from our previous findings in RA patients, mostly without biologics, showing GGO distributed in a panlobular or multilobular manner. The clinical outcome was favorable by treatment with trimethoprim-sulfamethoxazole and glucocorticoids. Conclusion The possibility of PCP should be intensively investigated in RA patients developing AoDILD while receiving biological agents.

Recently the high attention for fuel cell electric vehicle (FCEV) is pushing to construct the hydrogen supplying station for FCEV in the world. The hydrogen pressure supplied at the current test station is intended to be high for increasing the FCEV’s driving distance. The water electrolysis can produce cleanly the hydrogen by utilizing the electricity from renewable energy without emitting CO2 to atmosphere, when it is compared to be the popular reforming process of fossil fuel in the industry. The power required for the high-pressure water electrolysis, where water is pumped up to high-pressure, may be smaller than the power for the atmospheric water electrolysis, where the produced atmospheric hydrogen is pumped up by compressor, since the compression power for water is much smaller than that for hydrogen gas. In this study the ideal water electrolysis voltage up to 70MPa and 523K is estimated referring to both the results by LeRoy et al up to 10MPa and 523K, and to the latest steam table. By using this high-pressure water electrolysis voltage, the power required for high-pressure hydrogen produced by the high-pressure water electrolysis method is estimated to be about 5% smaller than that by the atmospheric water electrolysis method, by assuming the compressor and pump efficiency of 50%.

The prevailing view is that L-glutamate (Glu) functions as an excitatory amino acid neurotransmitter through a number of molecular machineries required for the neurocrine signaling at synapses in the brain. These include Glu receptors for signal input, Glu transporters for signal termination, and vesicular Glu transporters for signal output through exocytotic release. Although relatively little attention has been paid to the functional expression of these molecules required for glutamatergic signaling in peripheral tissues, recent molecular biological analyses including ours give rise to a novel function for Glu as an extracellular signal mediator in the autocrine and/or paracrine system in several peripheral and non-neuronal tissues, including bone and cartilage. In particular, a drastic increase is demonstrated in the endogenous levels of both Glu and aspartate in the synovial fluid with intimate relevance to increased edema and sensitization to thermal hyperalgesia in experimental arthritis models. However, to date, there is only limited information about the physiological and pathological significance of glutamatergic signaling machineries expressed by articular synovial tissues. In this review, we have outlined the role of Glu in synovial fibroblasts in addition to the possible involvement of glutamatergic signaling machineries in the pathogenesis of joint diseases such as rheumatoid arthritis.

爆心地からほぼ500m地点で採取した長崎被爆瓦の溶融表面に白雲母を検出材として固定し, 原子炉中性子照射に基づくフィショントラック (FT) を観測した. その結果, 残留核分裂核種を含む微粒子 (残存ホットパーティクル, HP) に由来する典型的な星状FTを裏面に比較して数十倍の高密度で観察できた. 20個の星状FT解析から0.72~5.7×107Pu原子がHP中に残存していると見積もれた. 更に, FT長が短いことを基に, HPが瓦表面から少々深い箇所に存在していることを確認した. 一方, 爆心から700mに位置する広島城被爆瓦からは, 石英粒子を抽出し, 再現法を用い青色熱ルミネセンス (BTL) 測定により, 13.0Gyの被曝線量を評価できた. 次いで, 長崎被爆瓦表面のルミネセンスの熱処理特性変化から, 約0.5mmの溶融被膜を除去した部位でも, 1100℃以上の被熱を受けていることを明らかにした. したがって, 残存HPはこの被熱温度をはるかに超えた融点の物質から成っていると判断した.

Previous studies (Frank, 1988; Toda, 1992) have shown the sense of unfairness to be an adaptive module within social environments. While adaptive modules can function effectively in practical contexts, they can be obstacles to solving insight problems (Knoblich, 1999; Hiraki & Suzuki, 1998; Abe & Nakagawa, 2007).   The purpose of this study is to test the effects of the sense of unfairness on problem solving. We hypothesize that the sense of unfairness will make it difficult to find the correct answer for this problem.To that aim, the ‘Transportation expenses problem’ is employed, which is a kind of insight problem with a social context.  In order to investigate our hypothesis, we asked participants to solve the problem. The results indicated that the participants did not make a correct and unfair response but a fair and incorrect one. Furthermore, we compare solution rates for the standard ‘Transportation expenses problem’ problem with isomorphic problems that do not involve need to think about unfairness. The results indicate that the solution rates for the isomorphic problems were higher than for the standard version of the problem. The results are supportive of our hypothesis.  The results of experiments suggest that the sense of unfairness interferes with the problem solving.In particular, it changes weight of each choice participants can select.

Understanding the SiO2/Si interface on atomic level is an important subject for fabricating silicon based superior devices. However, despite of many studies on the SiO2/Si interface, the interfacial electronic states have been evaluated as the average, but not specifically with individual states. In the present study, we successfully observed the electronic states of particular atoms at the SiO2/Si interface for the first time, using soft X-ray absorption and emission spectroscopy. The interfacial states are noticeably different from those of the bulk SiO2 and strongly depend on the intermediate oxidation states at the interface. Furthermore, comparing the experimental results to theoretical calculations reveals the local interfacial structures.

This survey explores the grief associated with the loss of a pet, and was carried out using a self-administered questionnaire. The questionnaires were handed out to 50 bereaved pet owners attending a public animal cremation service, and we received 18 responses. Participants responded within 0 to 44 (median 4) days of the death of their pet. Although most mental health problems immediately following mourning are presumed to be normal grief reactions, on the basis of several psychiatric scales, 8 of the 16 valid responses indicated depression and/or neurosis. Statistical analyses showed that the following factors were significantly associated with grief reactions: age of owner, other stressful life events, family size, age of dead animal, rearing place, and preliminary veterinary consultation.

The Sugashima ultramafic mass is one of the largest ultramafic bodies in the Mikabu belt, and is composed of a hornblende-poor part (Unit I) and a hornblende-rich part (Unit II). Unit I is a layered complex with laminar and convoluted structures probably formed as a crystal mush. Detailed petrographic studies reveal that orthopyroxene exists in almost all the rock types forming the igneous layering of Unit I: dunite, plagioclase wehrlite and olivine gabbro. Orthopyroxene crystals commonly occur adjacent to olivine crystals and locally show poikilitic textures enclosing olivine grains with rounded or irregular shapes, indicating their peritectic growth from a basaltic magma at a pressure lower than 0.9 GPa.

手術部位感染予防には抗菌薬の予防投与が重要である.当院感染対策チームでは,手術時のcefazolin(CEZ)およびcefmetazole(CMZ)の3時間毎投与を推奨してきたが,長時間手術では追加投与が適切に行われていないケースがみられた.そこで,抗菌薬供給方法を処方せんによる個人セット払いから手術室への定数配置へ変更し,追加投与実施状況の改善を試みた.併せて術前・術中投与の指示出し用スタンプを各病棟に配置した.供給方法変更前(2005年8月),供給方法変更後(2006年8月),ならびに電子カルテ稼動後(2007年8月)の3期間において,6時間を越える手術での抗菌薬術中追加投与の実施割合を調査した.各期間における対象件数と平均手術時間は2005年45例483分,2006年46例524分,2007年44例510分であった(p=0.46).必要投与回数の総和は各期間でそれぞれ99回,114回,106回であったのに対して,実投与回数の総和(実施率)は20回(20.2%),101回(88.6%),104回(98.1%)と,供給方法変更後に増加した(p<0.001).なお,2007年における前投与からの投与間隔は平均181分であり,210分を超えたのは全104回中2回のみであった.抗菌薬の供給を手術室定数配置に変更するなどの介入によって,抗菌薬術中追加投与の実施率を劇的に改善することができた.

In industrial arena, there are many solid-liquid two phase flow systems like mixing vessels, glass furnaces, solid-liquid separation equipments, etc. Numerical simulations are promising approach to understand the phenomena. Numerical analyses by the Eulerian-Lagrangian approach were performed in the past studies. The Eulerian-Lagrangian methods were applied to various solid-liquid flow systems without the free surfaces. On the other hand, numerical models which can treat the solid-liquid flows involving free surface were hardly developed so far. Hence, in the current study, we develop a Lagrangian-Lagrangian coupling methods to perform the fast simulation of the solid-liquid flows. The liquid phase were modeled by the Explicit Moving Particle Simulation (E-MPS) method. The E-MPS method can simulate the free surface flows easily. The DEM / E-MPS method was applied to a solid-liquid flow in a pipeline. The simulations were performed by changing the acoustic velocity. The simulation results, namely, the solid particle distribution, pressure and fluid velocity were compared in the present study. The DEM / E-MPS method is shown to make possible to perform the fast simulation by assuaging the acoustic velocity.

A new sensor to detect a smile of a person is proposed in this paper. When a person smiles, the shape of cheeks changes. The change is used for the detection of the smile. The sensor consists of a infrared LED, a photodiode and a few electronic parts. When the sensor detects a smile, at first infrared light is irradiated on a cheek. Then the sensor detects the smile by using the strength of light reflected from the cheek. As a result, the sensor is simple and can detect a smile.

Separation logic is an extension of Hoare logic to verify imperative programs with pointers and mutable data-structures. Although there exist several implementations of verifiers for separation logic, none of them has actually been itself verified. In this paper, we present a verifier for a fragment of separation logic that is verified inside the Coq proof assistant. This verifier is implemented as a Coq tactic by reflection to verify separation logic triples. Thanks to the extraction facility to OCaml, we can also derive a certified, stand-alone and efficient verifier for separation logic.
