Measurement of the A-Value of the Intersystem Transition in Al II at 2670 Å: Å Progress Report [PDF]
International Astronomical Union Colloquium, 1984 Ratios of intensities of spectral lines produced in the radiative decay of collisionally-excited levels of atomic ions are versatile indicators of electron density in astrophysical plasmas when one of the lines involves a metastable level (see the review by Feldman 1981 and references therein). Radiative transition probabilities (A-values) and electron

Reframing Colonial Korea's Forests Through Protection Forests: The Forests of Joseon (1938). [PDF]
Ber WissThis study examines The Forests of Joseon (1938), a forestry survey compiled by Tokumitsu Nobuyuki under Japanese colonial rule, as a key site of epistemic negotiation between imperial forestry science and Korean indigenous knowledge. Focusing on bíbo forests—geomantic forests believed to regulate energy flow between mountains and villages—the paper ...

Optical spectrum of the post-AGB Star HD56126 in the wavelength interval 4010-8790 Å Å [PDF]
Astrophysical Bulletin, 2007 The optical spectrum of the post-AGB star HD56126 identified with the infrared source IRAS07134+1005 is studied in detail using high spectral resolution observations (R = 25000 and 60000) performed with the echelle spectrographs of the 6-m telescope. A total of about one and a half thousand absorptions of neutral atoms and ions, absorption bands of C2,

Onomázein, 2023 Because the Chinese kinship and the Spanish one belong to the Sudanese type and Eskimo type respectively, there is a huge asymmetry and non-equivalence in the address terminologies. Although the Chinese kinship address terms, like the Spanish ones, have vocative function in the family context as well as in the non-family one, for the linguistic and ...

Root hair plasticity in cereals under abiotic stress. [PDF]
New PhytolAn integrative perspective on how to study the regulation of root hair plasticity to increase the resilience of cereals to abiotic stress. Summary Abiotic stress is a constant threat to crop growth and yield in the context of climate change. Root systems that can best adapt their architecture to environmental challenges contribute to enhanced ...

Shuitu Baochi Xuebao, 2002 采用对比分析的方法，研究了从自然土壤到森林土壤和农业土壤，最终演变为城市土壤的过程中，土壤质量的变化及其成因以及有机改土培肥措施对城市土壤质量有效性的影响。结果表明；城市土壤演变过程中土壤物理性质和养分含量发生了明显的变化。原始未受人为影响的五花草甸自然土壤的容重最小，农业老耕地土壤其次，森林土壤再次，城市土壤最大。城市绿化用地20－40cm土壤容重比别比森林土壤和农业土壤提高17.7%－43.7%和35.4%-93.9％。总孔隙度降低1.9%-13.0%和34.1%-52.4 ...

Shuitu Baochi Xuebao, 2022 为探究不同气候条件下土壤水力参数对土壤水长程相关性的影响, 利用HYDRUS-1D模型, 以湿润、半干旱和干旱气候区的气象数据为驱动, 结合生成的砂土和黏壤土土壤水力参数集, 模拟生成土壤水时间序列集; 而后, 利用去趋势波动分析法对生成的土壤水数据进行长程相关性分析。结果表明: (1)土壤水标度指数(h)介于0.570~1.915, 土壤水中存在显著的长程相关性。砂土中土壤水变化主要表现为持续性, 黏壤土中持续性和反持续性均较为显著。(2)土壤水长程相关性与土层深度、黏粒含量、干旱指数存在正相关关系。(
