1芬兰研究型教师教育述评显示文摘芬兰教育成功的重要原因之一是芬兰的研究型教师教育。新的教师教育课程要求所有的师范生都要开展一项他们自己的研究,以发展理论与实践结合的专业能力。本文介绍了芬兰研究型教师教育发展的背景、基本特点,以及实施的主要环节。Jouni Vlijrvi 陆璟 2009上海教育科研2009,,1:20
2Fluorescent SiC and its application to white light-emitting diodes显示文摘Fluorescent-SiC(f-SiC),which contains donor and acceptor impurities with optimum concentrations, has high conversion efficiency from NUV to visible light caused by donor-acceptor-pair(DAP) recombination. This material can be used as a substrate for a near UV light-emitting diode(LED) stack,and leads to monolithic white LED device with suitable spectral property for general lighting applications.In this paper,we describe basic technologies of the white LED,such as optical properties of f-SiC substrate,and epitaxial growth of NUV stack on the f-SiC substrate.Satoshi Kamiyama Motoaki Iwaya Tetsuya Takeuchi Isamu Akasaki Mikael Syvjrvi Rositza Yakimova 2011Journal of Semiconductors2011,32,1:5
3泥炭基质作物栽培中的灌溉问题显示文摘泥炭是一种具有多种优良特性的栽培基质。由于泥炭具有特殊的物理、化学性质,因此泥炭的水分物理性质也与矿质土壤明显不同。本文介绍了以泥炭为基质条件下的作物栽培过程的灌溉技术。Viljo Puustjrvi 孟祥君 王洪桥 孟宪民 2006腐植酸2006,,1:5
4阴离子竞争对磁赤铁矿纳米颗粒吸附砷酸盐的影响(英文)显示文摘This paper reports the effect of several competing anions on arsenate adsorption with maghemite nanoparticles.Sulphate(as SO4),nitrate(as NO3-N),phosphate(as PO4-P) ions and silicate(as SiO2) were studied in dual solution with arsenate.Moreover,the combined effect of ions and other water characteristics were examined with a natural groundwater sample which was spiked with a certain amount of arsenate.Arsenate batch adsorption experiments were carried out with two different kinds of maghemite—a commercially available one and a homemade one using the sol-gel process.Sulphate(≤250 mg·L-1) and nitrate(≤12 mg·L-1) had a negligible effect on the arsenate(0.5 mg·L-1) adsorption at pH 3.However,both phosphate(≤2.9 mg·L-1) and silicate(≤50 mg·L-1) had an adverse impact on arsenate(≤3 mg·L-1) adsorption at pH 7.Phosphate(≤1.5 mg·L-1) showed minimal competition with arsenate(0.5 mg·L-1),while silicate(≤10 mg·L-1) inhibition was insignificant for all studied As(V) concentrations at pH 3.The removal of arsenate from the groundwater sample was as efficient as from laboratory water for 0.5 mg·L-1 As(V) both at pH 3 and pH 7.T.Tuutijrvi E.Repo R.Vahala M.Sillanp G.Chen 2012Chinese Journal of Chemical Engineering2012,20,3:3
5Development of alexithymic personality features显示文摘The purpose of this paper is to review the current literature regarding the development of alexithymic personality features. Modern brain imaging technologies provide interesting data on the associations of alexithymia with different aberrations in brain function related to emotion regulation; however, the development of these deviations is poorly understood. A notable amount of research covers the relation of alexithymia to differentenvironmental factors. Many of these associations, for example, with low socio-economic status and general psychopathology in childhood, are well established. However, the retrospective and cross-sectional designs commonly used in these studies, as well as the use of self-report measures, hinder the ability to firmly establish causality. Certain individual developmental factors, such as lagging speech development and congenital cardiac malformations in childhood, have been associated with the development of alexithymia. Regarding the stability of alexithymia, a systematic review of the literature was conducted for this paper. In addition to being characterized as a personality feature in the general population, alexithymia also clearly has a state-like dimension that results in increases and decreases in alexithymic features in conjunction with mental disorder symptoms. An essential question is whether the alexithymic features in adulthood are, in fact, infantile features of a restricted ability to identify and describe emotions that simply persist in individuals through adolescence to adulthood. To firmly establish the roots of alexithymia development, longitudinal studies, particularly in younger populations, are needed. Furthermore, multifaceted study settings are encouraged.Max Karukivi Simo Saarij?rvi 2014World Journal of Psychiatry2014,4,4:2
