Suppression of the low-temperature phase-separated state under pressure in (Eu1−x_{1-x}Gdx_{x})0.6_{0.6}Sr0.4_{0.4}MnO3_{3} (x=0,0.1x=0,0.1)

We have demonstrated the effect of pressure on the steplike metamagnetic transition and its associated magnetostriction in (Eu$_{1-x}$Gd$_{x}$)$_{0.6}$Sr$_{0.4}$MnO$_{3}$ ($x=0$ and 0.1). The critical field initiating the field induced ferromagnetic transition in both samples is lowered by the applied pressure. The further application of external pressure up to 1.2 GPa on the $x=0$ parent sample causes a spontaneous ferromagnetic transition with a second-oder like character, leading to collapses of the steplike transition and its concomitant lattice striction. These findings indicate a crucial role of the low-temperature phase separated state characterized by a suppressed magnetization upon decreasing temperature.Comment: 8 pages, 6 figures. arXiv admin note: text overlap with arXiv:1006.145

京都市内の単身者向け住宅の揮発性有機化合物に関する実測調査

An investigation of indoor VOC concentration and a questionnaire survey were carried out in 17 single-room apartments (apartments for single persons) in Kyoto city. The results are: 1) In one apartment, the concentration of TVOC exceeded the provisional objectives set by the Ministry of Health, Labor and Welfare. In 12 apartments, the concentration of HCHO exceeded the guideline of the Ministry. 2) No correlations were found between VOC concentration and apartment age or VOC concentration and years of occupancy. 3) In apartments with high VOC concentration, new furniture made of plywood or two or more chemicals were present. 4) Few residents open windows often but most residents are accustomed to using ventilation fans. 5) Many residents have not taken any measures to cope with the sick-house syndrome, despite such measures being in their own self-interest. 6) It appears that people who are more concerned with the sick-house syndrome have more subjective symptoms of the syndrome

Measurements of atmospheric muon spectra at mountain altitude

We report new measurements of the atmospheric muons at mountain altitude. The measurement was carried out with the BESS detector at the top of Mt. Norikura, Japan. The altitude is 2,770 m above sea level. Comparing our results and predictions given by some interaction models, a further appropriate model has been investigated. These studies would improve accuracy of atmospheric neutrino calculations.Comment: Mean momentum in Table 1 was correcte

Measurements of Cosmic-ray Low-energy Antiproton and Proton Spectra in a Transient Period of the Solar Field Reversal

The energy spectra of cosmic-ray low-energy antiprotons and protons have been measured by BESS in 1999 and 2000, during a period covering the solar magnetic field reversal. Based on these measurements, a sudden increase of the antiproton to proton flux ratio following the solar magnetic field reversal was observed, and it generally agrees with a drift model of the solar modulation.Comment: 4 pages, 4 figures, revised version accepted for publication in Phys.

Assessment of method for measuring clo value using human body – Assessment of method for measuring clo value that assumes human body temperature adjustment

In order to make it possible to measure the clo value in various postures, we are studying the measurement method using the human body. Our previous researches showed that clo value measured with the human body is less than that measured with a “constant temperature control”-type thermal manikin. In our previous experiments, human body changes its skin temperature in response to the amount of clothing or changes in the temperature to maintain heat loss, while a “constant temperature control”-type thermal manikin changes its heat loss in response to the temperature or amount of clothing. Human body reaction is similar to “constant heat dissipation” -type thermal manikin. In order to improve the clo value measurement method using the human body, clo value of same clothing by thermal manikin which changed control method to “constant temperature” and “constant heat dissipation” were measured. Relational expressions of thermal insulation of clothes measured by different control methods were shown

Thermal environment mitigation effects in suburban area

The purpose of this paper is to clarify the relationship between the physiological and psychological responses of the human body and the outdoor environment evaluation index ETFe (enhanced conductioncorrected modified effective temperature). The experiments were carried out in summer. For the measurements, observation points were selected with consideration for the condition of the ground surface such as bare ground where the surface is gravel or soil; paved ground such as concrete, asphalt or blocks; green areas covered in plants and water surfaces and with consideration for the condition of the sky factor due to buildings or trees. 19 observation points were chosen. Subjects were 38 healthy young. ETFe that was considered to report neither hot nor cold, thermally neutral sensation, was 30.6°C. ETFe that was considered to report neither comfortable nor uncomfortable comfort was 35.5°C. It was considered that the threshold for the human body with regards to thermal environment stimuli in an outdoor space is higher than the thermal environment stimuli in a summer indoor space
