nanosheet catalyst as an efficient tri-functional catalyst
No full textIn this study, a nickel (Ni)-doped 1T-MoS2 catalyst, an efficient tri-functional hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR) catalyst, was massively synthesized at high pressure (over 15 bar). The morphology, crystal structure, and chemical and optical properties of the Ni-doped 1T-MoS2 nanosheet catalyst were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and ring rotating disk electrodes (RRDE), and the OER/ORR properties were characterized using lithium-air cells. Our results confirmed that highly pure, uniform, monolayer Ni-doped 1T-MoS2 can be successfully prepared. The as-prepared catalysts exhibited excellent electrocatalytic activity for OER, HER, and ORR owing to the enhanced basal plane activity of Ni doping and formidable active edge sites resulting from the phase transition to a highly crystalline 1T structure from 2H and amorphous MoS2. Therefore, our study provides a massive and straightforward strategy to produce tri-functional catalysts.

Development and validation of simultaneous HPLC-PDA analysis method for quality control of Hwang-ryeon-hae-dok-tang: An analytical quality by design approach
No full textThis study introduces an advanced analytical method for quality control of botanical drugs, focusing on Hwang-ryeon-hae-dok-tang (HRHDT), a traditional herbal prescription utilized for inflammation, gastritis, fever, and hypertension. Botanical drugs pose a challenge due to their complex composition, requiring reliable and robust analytical techniques. Our step-by-step procedure included defining the analytical target profile, risk assessment, screening and optimizing design of experiment, measuring the design space, and Monte Carlo simulation. The established HPLC-PDA method enables the simultaneous analysis of four major compounds (geniposide, baicalin, palmatine, and berberine) present in HRHDT. The optimized conditions involve a gradient elution with acetonitrile and water, both containing 0.1% trifluoroacetic acid, a 32 °C column temperature, 254 nm detection wavelength, and 1.0 mL/min flow rate. A successful validation demonstrated excellent linearity (R2: 0.9984–0.9989) and accuracy (recovery: 100.61%–102.44%), with precise repeatability and intermediate precision (%RSD: 0.39%–0.83%). These results further confirm the reliability and accuracy of the analytical method. Overall, our design-based approach not only facilitated the development of robust analytical methods but also allowed for flexible operation ranges. Therefore, this methodology holds significant potential for ensuring the quality of botanical drug products within the pharmaceutical industry.</p
Application Research of 3D Printing Technology on Dress Forms
No full textAbstract— Dress form is an essential tool in the clothing-making process for pattern block development, draping and quality inspection. However, it is noted that a single dress form is not applicable for a large variety body shapes. There are adjustable dress forms and custom-made dress forms to attempt to make up for the insufficiency of conventional dress forms. However, such types of dress forms are rather costly and their effectiveness is debatable. With this is mind, a customised adjustable kit for the dress form was developed, with the aim to cover different sizes and shapes more precisely. The kit adopts 3D printing technology which enables generating and changing the shape of components efficiently

Writing systems, reading processes, and cross-linguistic influences reflections from the Chinese, Japanese and Korean languages Bilingual processing and acquisition ;, 7./ edited by Hye K. Pae.
No full textIncludes bibliographical references and index.This book provides readers with a unique array of scholarly reflections on the writing systems of Chinese, Japanese, and Korean in relation to reading processes and data-driven interpretations of cross-language transfer. Distinctively broad in scope, topics addressed in this volume include word reading with respect to orthographic, phonological, morphological, and semantic processing as well as cross-linguistic influences on reading in English as a second language or a foreign language. Given that the three focal scripts have unique orthographic features not found in other languages - Chinese as logography, Japanese with multi-scripts, and Korean as non-Roman alphasyllabary - chapters expound script-universal and script-specific reading processes. As a means of scaling up the body of knowledge traditionally focused on Anglocentric reading research, the scientific accounts articulated in this volume importantly expand the field's current theoretical frameworks of word processing to theory building with regard to these three languages.Written languages, East-Asian scripts, and cross-linguistic influences : an introduction / Hye K.

Identification of phosphorylation sites of TOPORS and a role for phosphorylated residues in the regulation of ubiquitin and SUMO E3 ligase activity:
No full textTOPORS is the first example of a protein that possesses both ubiquitin and SUMO E3 ligase activity. The ubiquitination activity maps to a conserved RING domain in the N-terminal region of the protein, which is not required for sumoylation activity. Similar to other E3 ligases, it is likely that the ubiquitin and sumoylation activities of TOPORS are regulated by post-translational modifications. Therefore, we employed mass spectrometry to identify post-translational modifications of TOPORS. Several putative phosphorylated regions were identified in conserved regions of the protein. We investigated the role of phosphorylation of serine 98, which is adjacent to the RING domain, in both cells and in vitro. Mutation of serine 98 to aspartic acid resulted in an increase in the ubiquitin ligase activity of TOPORS both in cells and in vitro. In addition, this mutation increased the binding of TOPORS to the E2 enzyme UbcH5a. Conversely, a phospho-deficient mutant (S98A) exhibited little change in ubiquitin ligase activity compared to wild-type TOPORS, both in cells and in vitro. Neither of the mutants affected the localization of TOPORS to punctate nuclear regions. In addition, neither mutant affected the SUMO ligase activity of TOPORS in cells or in vitro. Our findings indicate that phosphorylation of serine 98 regulates the ubiquitin but not the SUMO ligase activity of TOPORS, consistent with a potential binary switch function for TOPORS in protein ubiquitination versus sumoylation.Ph.D.Includes bibliographical references (p. 99-107)by Hye-Jin Par
Stabiliteit van C-Star steenzetting bij golfaanval: Vergelijkend onderzoek zetstenen voor dijken
No full textHet “Vergelijkend onderzoek zetstenen voor dijken” is aan Deltares opgedragen door Rijkswaterstaat WVL, namens het Projectbureau Zeeweringen, het Project Afsluitdijk, het Corporate innovatieprogramma van RWS, de drie noordelijke waterschappen (Wetterskip Fryslân, Waterschap Noorderzijlvest, Waterschap Hunze en Aa’s, in het kader van een Projectoverstijgende Verkenning Waddenzeedijken van HWBP) en een vijftal marktpartijen. Het doel van het onderzoek is het vaststellen van de stabiliteit bij golfaanval van een aantal moderne type steenzettingen voor toepassing op primaire waterkeringen in Nederland. Daarnaast wordt van enkele type steenzettingen ook de golfoploopremmende werking gemeten. Het in dit rapport beschreven deel van het onderzoek betreft de stabiliteit van zetstenen van het type C-Star, waarvoor Berding Beton (in samenwerking met LBN Betonproducten B.V. en Noppert Beton) als marktpartij in het onderzoek participeert. Om de stabiliteit bij golfaanval van de C-Star te bepalen is er grootschalig onderzoek uitgevoerd in de Deltagoot van Deltares. De schaal van dit onderzoek was 1:2. Alle maten die in dit rapport zijn gerapporteerd betreffen de waarden op modelschaal, dus zoals ze aanwezig waren in de Deltagoot. De beproefde steenzetting had een toplaagdikte van 0,175 m. Onder de C-Stars was een filterlaag aangebracht van steenslag met daaronder een geotextiel. De constructie is beproefd met drie proefseries. De eerste twee series bestonden uit korteduurproeven met in iedere serie een gelijkblijvende brekerparameter. De derde serie bestond uit twee langeduurproeven met vaste golfcondities. Na iedere proef is de vervorming en eventuele schade aan het talud geregistreerd. Op basis van de proefresultaten en de rekenresultaten met Steentoets is de stabiliteitsfactor afgeleid. Deze blijkt voor de C-Stars in combinatie met Steentoets2014 (versie 14.1.2.1) fstabiliteit = 1,17 te zijn. Deze factor is opgenomen in Steentoets2015.Steenzettinge
Park Geun-hye: als Präsidententochter zur ersten Staatspräsidentin Südkoreas?
No full textDie ehemalige konservative Oppositionsführerin Park Geun-hye (2004-2006) gilt als aussichtsreiche Kandidatin für die kommenden Präsidentschaftswahlen im Dezember 2007. Die Tochter des so genannten Entwicklungsdiktators Park Chung-hee, der während seines Regimes (1961-1979) den wirtschaftlichen Aufschwung des Landes in die Wege leitete, konnte oder wollte bis dato nicht aus dem Schatten ihres Vaters heraustreten. Sie nutzte die Nostalgie für ihren Vater während der regionalen Wirtschaftskrise Ende der 1990er als Einstieg für ihre politische Laufbahn.
