Research on the May Fourth spirit and its influence in Lin Hai-yin\ue2s novel.
No full textThe thesis is a study of the May Fourth Spirit in Lin Hai-yin\ue2s novel. Her acceptance of the May Fourth literature thoughts and May Fourth women\ue2s novel had affect her writing. The first chapter is the research history of Lin Hai-yin\ue2s novel and theory of this thesis: Aesthetics of reception, narratology and Feminist Literary Criticism.
In the second chapter we research Lin Hai-yin\ue2s personal history during the time of May Fourth. The May Fourth Spirit had affect her vision, but because her marginal perspective, which made her novel more objective and unique. The third chapter is the influence of May Fourth women\ue2s novel in Lin\ue2s. On the theme, subject matter, writing strategy, she followed these writer\ue2s strategy, but present more profound thoughts which different from them.
In the fourth chapter we discuss the plot and characters of Lin\ue2s novel. The narrator in Lin\ue2s novel is usually a woman. Through these women\ue2s eyes, we saw a women\ue2s world that has solid sisterhood. We also saw the faces of men in her novel which are weak and escape from making decision are not the same with the traditional men\ue2s character kinds. And there also shows her concern of society through these characters.
The last chapter is discussing Lin\ue2s novel\ue2s acceptation and influences in Taiwan. In past criticism, her novel\ue2s theme had been seen like homesick. But the writing strategy of women during the anti-commu period is selected themes that considered not important, like love, marriage\ue2\ua6etc. to show they concerned society by these characters\ue2 fate. In conclusion we affirmed Lin Hai-yin\ue2s novel has great value, and she is one of the most important novelists in the 1950\ue2s age

Taxonomic notes: —Until now, the genus Sporoxeia consists of eight species including the new species. Sporoxeia vietnamensis can be easily distinguished from other species of Sporoxeia by the stiffly papery leaf blades, larger and densely horned hypanthia, and larger calyx lobes and petals. Its horned hypanthia and nearly folded calyx lobes are uncommon in the Asian Melastomataceae. The horned hypanthia also occur to some species of Pternandra Jack (1822: 60) of the tribe Kibessieae, e.g., P. echinata Jack (1822: 3). An identification key to the species of Sporoxeia is provided below.Published as part of Thuy, Nguyen Thu, Zeng, Sijin, Hai, Do Van, Hoan, Duong Thi, Lin, Zheli & Deng, Yunfei, 2022, Sporoxeia vietnamensis (Melastomataceae), a new species from northern Vietnam, pp. 283-290 in Phytotaxa 558 (3) on pages 284-289, DOI: 10.11646/phytotaxa.558.3.4, http://zenodo.org/record/700309
Spectrometric study of condensed phase species of thorium and palladium-based modifiers in a complex matrix for electrothermal atomic absorption spectrometry
No full textThe chemical and morphological transformations of condensed phase species of a thorium-based modifier were studied over the temperature range 200–2500 °C, without and with the presence of aluminium and silicon as matrix components, and in some instances, arsenic as an analyte element. A similar study was also conducted with palladium as the modifier, for comparison. Results were derived using scanning electron microscopy (SEM), energy dispersive (ED) X-ray spectrometry, Raman microanalysis and attenuated total reflectance (ATR) Fourier transform-infrared (FT-IR) spectrometry. Comparable results were found using pyrolytic and non-pyrolytic graphite platforms, with processes occurring at slightly higher temperatures on the pyrolytic graphite platform. With thorium as the modifier, metal oxides were the predominant species on the platform surface at relatively low temperatures (<1500 °C), whereas metal phases became prevalent at high temperatures, when thorium and aluminium tended to behave independently from one other. Some spatial variations in the composition of the salt residues on different regions of the platform were observed (from the region closest to the slot in the tube, to the region furthest from the slot). Nonetheless, thorium metal remained on the graphite platform to higher temperatures than did aluminium metal. In the presence of arsenic, the existence of mixtures of thorium and arsenic oxides, just before the appearance temperature of gas phase arsenic atoms, was confirmed by SEM studies, ED X-ray spectra and Raman microanalysis. This suggests that any modifying effect of thorium on arsenic occurs while the modifier is in the oxide phase rather than in the metal phase. The presence of silicon added as silica, did not influence significantly the thermochemical behaviour of mixtures of thorium and aluminium. However, coexistence of silicon and arsenic oxides at the appearance temperature of the atomic absorption signal of arsenic was obtained, confirming that silicon can act as an internal modifier for arsenic. In the presence of palladium, aluminium exhibited greater interaction with the modifier; consequently, aluminium metal was retained on the platform surface to higher temperatures than thorium, which could explain how interference effects of aluminium on e.g. arsenic are avoided or reduced. Similarly, there was evidence for interaction of palladium and arsenic in the reduced state. However, when aluminium and silicon were present, the transformation of the palladium oxide to the metallic state was affected, which could diminish the modifying benefits of palladium for arsenic in the presence of aluminium
HAI-2 species in Caco-2 human enterocytes.
No full textCaco-2 human enterocytes were incubated in PBS as a non-activation control (lanes 1) or a phosphate buffer pH 6.0 for 20 min to induce matriptase zymogen activation (lanes 2). Matriptase species were subsequently immunodepleted from the lysates that had been prepared from Caco-2 cells in which matriptase zymogen activation was induced (lanes 3). The three Caco-2 lysates were then analyzed by immunoblot for HAI-2 species with significant N-glycan branching using HAI-2 mAb DC16 (HAI-2 DC16), HAI-2 species without N-glycan branching using HAI-2 mAb XY9 (HAI-2 XY9), and matriptase species using matriptase mAb M24 (Total MTP). Small quantities of mouse IgG shed from the beads used for immunodepletion can be seen as a band of approximately 150-kDa (lanes 3 in each panel) is indicated by an arrow. The HAI-2 species in Caco-2 cells have been observed in at least 10 independent experiments. The induction of matriptase zymogen activation in Caco-2 cells and the immunodepletion of matriptase species has been carried out at least 3 times. Representative data are shown.</p
An Analysis of <i>Judge Lin</i>
No full textBiography of Lin Wen Zhong Gong has another way to call, that is Judge Lin. The leading character is Lin Ze-Xu. This book is based on functionary experience of Lin Ze-Xu, with the captivating plots of court case, helping by highly skilled military attach\uc3\ua9s and chivalrous knights, and the history facts of Opium War. It makes Lin Ze-Xu\ue2s Confucian temperament and tragic mood more, also contrasts with author\ue2s sorrow and furiousness for the politics at the time. History, court case, martial arts\ue2\ua6\ue2\ua6etc. are essence of this book and it broadens the way of this writing style.
The topic of the thesis is \ue2An Analysis of Judge Lin\ue2. The following thesis will be divided into six different chapters. The introduction is Chapter one of the thesis, which is including researching motive and purpose, literature review of predecessors, researching version by existing information, raising questions, choosing research methods and arranging chapters. In chapter Two, I discuss the study of characters of Lin Ze-Xu, also makes a deep analysis of author\u27s purpose of writing him. In chapter Three, I analyze supporting actors and actress. Meanwhile, I illustrate author\u27s purpose of writing supporting actress because the author had different manner to describe supporting actress. Moving to the Chapter Four, I mainly focus on the plots of Judge Lin, and organize cases of Lin Ze-Xu and his subordinates to understand features of cases. In Chapter Five, I represent the causes of Opium War. China and England had difference of opinions of opium. Therefore, it is easier to comprehend what the author\u27s purpose is. In the last chapter I summarize the main points of the preceding chapters and confirm particularity of Judge Lin
