Near-Infrared Extinction in The Coalsack Globule 2

We have conducted J, H, and Ks imaging observations for the Coalsack Globule 2 with the SIRIUS infrared camera on the IRSF 1.4 m telescope at SAAO, and determined the color excess ratio, E(J-H)/E(H-Ks). The ratio is determined in the same photometric system as our previous study for the rho Oph and Cha clouds without any color transformation; this enables us to directly compare the near-infrared extinction laws among these regions. The current ratio E(J-H)/E(H-Ks) = 1.91 +- 0.01 for the extinction range 0.5 < E(J-H) <1.8 is significantly larger than the ratios for the rho Oph and Cha clouds (E(J-H)/E(H-Ks) = 1.60-1.69). This ratio corresponds to a large negative index alpha = 2.34 +- 0.01 when the wavelength dependence of extinction is approximated by a power law which might indicate little growth of dust grains, or larger abundance of dielectric non-absorbing components such as silicates, or both in this cloud. We also confirm that the color excess ratio for the Coalsack Globule 2 has a trend of increasing with decreasing optical depth, which is the same trend as the rho Oph and Cha clouds have.Comment: 13 pages, 5 figures, and 2 tables, Ap

Species, size, and location of “giant trees” in Tokyo’s urban area and western suburbs

The Japanese landscape has been characterised by the occurrence of ancient, massive trees described here as “giant trees”, and many of these have had major historic, cultural, and religious significance. However, modern Japan has experienced significant and rapid urbanisation and in relation to ancient woods and trees, “cultural severance” too. This study identified the species, size, and locations of the giant trees growing in Tokyo’s urban centre and its western suburbs, by conducting field surveys and collecting data from published studies. Classification of sites according to tree girth, with giant trees, revealed six broad locations: (1) forest and agricultural lands of managed secondary and later abandoned woodland with deciduous, broad-leaved trees; (2) public gardens, comprising useful and ornamental plants introduced from southern Japan; (3) parks, including mostly exotic species; (4) shrine sites, including Zelkova serrata, conifers, and evergreen broad-leaved trees; (5) temple sites, including many Torreya nucifera; and (6) Imperial lands, with rare species of trees in low numbers. The highest percentage of giant trees (36%) were found in parks, followed by temple and shrine sites (32%), whereas only 10% were found in other historical places. This study highlights the importance of studying giant tree habitats and history and identifying the relationships between human activities and living trees

Green energy in the service of mankind

This paper presents the project called “Vetrosvet” that has been carried out in Tomsk region by students of Tomsk Polytechnic University. This project has a great value as it is focused on popularizing green energy and renewable sources in Russia and, mainly, in the Tomsk region. Tomsk region is known as a center of innovation technology. That is why the region has been chosen for caring out the project. Moreover, the usage of wind turbines is more effective than solar panels in this region. It can be explained by the small amount of sunny days in Siberian region. The wind turbines are put together in the development laboratory at Tomsk Polytechnic University. The results of this project are presented in this paper

慢性肺疾患の早産児におけるプロテインC経路 : 前向き研究

Background: Chronic lung disease (CLD) is a major neonatal pulmonary disorder associated with inflammation. Recent studies have shown that protein C anticoagulant pathways, such as those for protein C (PC), protein S (PS), and thrombomodulin (TM), could be useful indices for reflecting pulmonary injury. However, the involvement of these factors in preterm infants with very low birthweight (VLBW) who have developed CLD remains to be investigated. Here, we investigated whether PC pathway-related factors could predict the development of CLD in preterm infants with VLBW. Methods: We collected plasma samples from 26 preterm infants with VLBW (13 each from those with and without CLD) at the time of birth and measured TM, PC, and PS levels in their plasmas. We analyzed prospectively the relationship between these factors in infants with and without CLD. Results: There were significant differences in gestational age, birthweight, Apgar score (5 min), and duration of mechanical ventilation between the CLD and non-CLD groups. No significant differences in the PC and PS levels at birth were observed between the two groups, whereas the TM levels in the CLD group were significantly higher than those in the non-CLD group (P = 0.013). The TM levels correlated with gestational age and duration of mechanical ventilation. However, covariance analysis demonstrated that gestational age was significantly associated with TM levels, and consequently, development of CLD was not associated with TM level at birth. Conclusions: Thrombomodulin, PC, and PS levels at birth could not predict the development of CLD in preterm infants with VLBW.博士（医学）・甲第850号・令和4年9月28日© 2022 Japan Pediatric Society.This is the peer reviewed version of the following article: [https://onlinelibrary.wiley.com/doi/10.1111/ped.15221], which has been published in final form at [https://doi.org/10.1111/ped.15221].

Status of 48Ca double beta decay search in CANDLES

We study a strategy to reduce veto-time in the search for neutrino-less double-beta decay (0υββ) with CANDLES-III system. We develop a new likelihood analysis and apply it to our new Run010 data. We show that we can increase the un-vetoed live-time by 11.8%. Thanks to this improvements, We expect to increase a limit on the life-time of 0υββ by a factor of three by analyzing both Run009 and Run010 data

「農業体験学習事業」 農業体験を通した地域連携による家政学群学生の学び 平成23（2011）～ 25（2013）年度和洋女子大学教育振興支援助成成果報告

平成23年度から同25年度に和洋女子大学教育振興支援助成を受け、農業体験を通して家政学群学生の学びを促進した。体験実習にあたり、学外の農業従事者、自治体（長野県立科町、千葉県市川市、千葉県神崎町）の農業担当職員や農業委員、JA職員、農業に関するNPO法人スタッフ、静岡大学、千葉大学の関係者など、様々な地域の方々と交流し、指導されて実践した農業体験により、学生はコミュニケーション能力や連携力を身につけた。また、農作物や花を育てる方法を学び、食べ物や花を育てることは生きている植物を自然と共生しながら育てることであることを認識し、農業の大変さと喜びも体験した。学内では農業ファッション制作の活動も行い、農業する女性のための作業服づくりを初めて体験し、専門技術の修得にも繋げた。また、収穫物から加工食品を開発、販売する活動も行い、地域の人たちから高い評価を受けた。現場での作業体験は学生同士や教員と学生間の協力や協調の体験となり、同時に様々な活動体験から実践力、判断力などの育成に繋がった。これらの農業体験を通して実施した実践的学習は、家政学を学ぶ学生に大きな刺激と成長をもたらしたと考える。本稿では本取り組みにおける家政学群学生の学びの内容と学生の様子について報告した

Synthesis and coordination behavior of Cu(I) bis(phosphaethenyl)pyridine complexes.

Cu(I) complexes bearing BPEP as a PNP-pincer type phosphaalkene ligand undergo effective bonding interactions with SbF(6)(-) and PF(6)(-) as non-coordinating anions to give [Cu(SbF(6))(BPEP)] and [Cu(2)(BPEP)(2)(μ-PF(6))](+), respectively [BPEP = 2, 6-bis(1-phenyl-2-phosphaethenyl)pyridine]. NMR and theoretical studies indicate a reduced anionic charge of the μ-PF(6) ligand, which is induced by the strong π-accepting ability of BPEP
