LETUSAN KRAKATAU 1883 DAN KORBAN-KORBANNYA DI DESA NELAYAN KARANGANTU BANTEN: SUATU KESAKSIAN ONG LENG YAUW
No full textThis article is based on Ong Leng Yauw’s testimony about Krakatoa eruption in 1883 and the victims in the Karangantu village Banten. Yauw Leng Ong is a Chinese, born and raised in Karangantu Beach Banten. He was 14 years old when the Krakatoa eruption occurred on August 27, 1883. From his testimony, the 1883 eruption of Krakatoa caused a tsunami that devastated Karangantu village Banten. Humans and animals corpses strewn among the rubble that blanketed the Krakatoa volcanic ash. There were only four survivors, Yauw Leng Ong, Ong Seng Boen, and two sisters Roti Nio and Biskoeit Nio
Multi-word Sequences in Learner Corpora: A Corpus Analysis of Lexical Bundles / Ang Leng Hong and He Mengyu
No full textThere have been longstanding attempts to establish frequency profiles of words which are
specific to academic register in order to facilitate learners in composing fluent academic
writing. A more noteworthy effort was by Coxhead who proposed the Academic Word List
(Coxhead, 2000). Recent developments in the field have increasingly regarded multi-word
sequences such as lexical phrases, lexical bundles, formulas and clusters as crucially important
and functionally significant in the academic contexts (Simpson-Vlach & Ellis, 2010). The present
study adopts a corpus-based approach to identify a type of multi-word sequence, i.e., lexical
bundles in student academic writing. Lexical bundles retrieved from a corpus of Asian college
student essays and a corpus of British university-level student writing are identified, analysed
and compared using corpus-linguistic techniques. The results of the analysis show that certain
lexical bundles share the same keywords. This keyword sharing characteristic suggests that
lexical bundles are internally analysable although they are initially retrieved as continuous
strings of words. Besides, there is no significant difference in the functional use of lexical
bundles between the Asian learners and British native students. However, both Asian learners
and British university students are found to prefer different types of lexical bundles. Simpson-
Vlach and Ellis’s (2010) functional classification taxonomy (e.g., referential expressions, stance
expressions, discourse organising functions) is used to categorise and analyse the items
functionally. Finally this paper discusses the pedagogical implications drawn from the analysis

Discussion. The records above apparently all refer to a single Martinique specimen, which we have not found. The identity of this specimen is unknown at this time, thus it is placed incertae sedis. In spite of three species names being involved, there is only a single record here. We can trace the record to Leng and Mutchler (1914), but no voucher has been found. It may originate earlier, but we have been unable to find it. In 1957, Marcuzzi did not cite a specimen for his Martinique record of D. perforatus in his table. In 1962, he dropped the D. perforatus record for Martinique, rather moving it to D. hummelincki with a “?” In 1977, D. hummelincki was replaced with D. mulsanti, and the Martinique record retained. Lastly, in 1984, the Martinique record for D. perforatus was reinstated by Marcuzzi, apparently forgetting he moved it to D. hummelincki / mulsanti, which was also retained. Peck (2011b, 2016) listed it twice, under two names, without understanding the records.Published as part of Hart, Charles J. & Ivie, Michael A., 2016, A Revision of the Genus Diastolinus Mulsant and Rey (Coleoptera: Tenebrionidae), pp. 485-540 in The Coleopterists Bulletin 70 (3) on pages 485-540, DOI: 10.1649/0010-065X-70.3.485, http://zenodo.org/record/695431
Chao leng 23Na-87Rb hun he wu zhong de ji hua zi he zi xuan qi ti
No full textPh.D.An ultracold Bose-Bose mixture of ⁸⁷Rb and ²³Na provides an excellent plat- form for studying not only few-body but also many-body physics. A key feature of ultracold atoms mixture is the tunable interspecies interaction, which is facilitated by the Feshbach resonance. In this thesis, we study the behavior of ultracold Bose-Bose mixture under different interspecies interaction. The studies are divided into two different topic, each of them corresponds to a different regime of many-body physics.The primary research is about the behavior of the impurities in Bose-Einstein condensate, which is also known as the polaron state. We use the radio frequency spectroscopy to probe the spectra of the ⁸⁷Rb impurities in a ²³Na Bose-Einstein condensate. For the trap-averaged spectra, near quantitative agreement between the theory and experimental data can be observed without any fitting parameters. Besides, we develop a fitting model which helps us find the energy and residue immune from the trap-averaging. The results shows the deviation of polaron energy and residue at strong inter- acting regime, which can not be explained by field-theoretic approach and two-body variational theory.The second research investigates the manipulation of heteronuclear spinor dynamics by microwave and light field. Previously, we have observe the first heteronuclear spin coherent heteronuclear spin oscillation in a spin-1 mixture of ⁸⁷Rb and ²³Na atoms. Here, we observe the spin population oscillation start from a pure |0, 0⟩ mixture of ⁸⁷Rb and ²³Na. We then demonstrate controlling of the spin dynamics by either a detuned microwave field or a laser beam, which selectively dress the energy levels of ⁸⁷Rb atoms. The results introduce a new techniques for investigating spin dynamics with fast temporal and high spatial resolutions.基於⁸⁷Rb 和²³Na 的超冷波色混合氣體給少體以及多體物理提供了極佳的實驗平台。而對於异核混合氣體，其最關鍵的特性即是可以通過Feshbach共振調控异核原子間的相互作用。在這篇論文中，我們研究了超冷波色混合氣體在各種异核相互作用下的一些特性，具體的研究包括了多體物理下兩個研究方向。這篇論文的第一個方向是研究雜質原子在波色愛因斯坦凝聚中的特性即波色極化子問題。我們使用射頻波譜學探測⁸⁷Rb 雜質在²³Na 凝聚態中的能量譜。通過對阱中整體信號求平均的方式，在不需要任何擬合變量的前提下，我們所探測的能量譜與場論方法的理論計算幾乎一致。我們進一步利用擬合模型來去除整體平均所帶來的失真，得到了特定凝聚態密度下極化子的能量和殘餘（residue）。我們發現這些結果與場論方法以及基於兩體理論的變分法下得到的數值在强相互作用區域發現了明顯的偏差。這篇論文的第二個研究方向是使用微波和光場操控异核旋量混合氣的自旋交换動力學過程。在之前的研究中，我們在F=1 的⁸⁷Rb-²³Na 混合氣體中觀察到了首個异核間的相干自旋動力學。基於之前的研究，我們進一步觀察了|0, 0⟩ 初始態下不同自旋態原子數隨時間的變化。我們之後借助這個動力學過程演示了通過失諧微波以及光場下⁸⁷Rb 不同自旋態的能量平移對動力學的操控。這項研究給自旋動力學的快速和高分辨率操控提供了新的方式。Li, Lintao = 超冷23Na-87Rb混合物中的極化子和自旋氣體 / 李林濤.87 and 23 in title are superscript."December 2020."Thesis Ph.D. Chinese University of Hong Kong 2021.Includes bibliographical references (leaves 135-149).Abstracts also in Chinese.Title from PDF title page (viewed on March 23, 2022).Li, Lintao = Chao leng 23Na-87Rb hun he wu zhong de ji hua zi he zi xuan qi ti / Li Lintao
