Identifications of polyphenols and quantification of anthocyanidins in grapes and grape-derived products
No full textPolyphenols in grapes and grape-derived products have attracted public and scientific attention due to their numerous protective roles to human health. A rapid and comprehensive qualitative method was developed to characterize the different classes of polyphenols, such as anthocyanins, flavonols, phenolic acids and flavanols/proanthocyanidins, in grapes and grape-derived products. The detection was achieved by two runs with same HPLC gradient in different MS ionization modes and mobile phase modifiers (positive mode and 0.4% trifluoroacetic acid for anthocyanins and flavonols, negative mode and 0.1% formic acid for phenolic acids and flavanols). Under the optimized LC/MS conditions and based on the analysis of the MS and UV data and in comparison with the authenticated standards, a total of 53 polyphenolic compounds were successfully separated and individually identified including 33 anthocyanins, 12 flavonols, 4 phenolic acids and 4 flavanols/proanthocyanidins. With the method developed, a survey was conducted to qualitatively assess and compare the composition of polyphenols among 29 grapes and grape-derived products. To facilitate the quantitation of the major class of polyphenolic anthocyanidins, a simple and precise acid assisted hydrolysis method was established for the quantitation of anthocyanidins in grape juice samples, grape berries and grape skins using LC/MS. Five most common anthocyanidins of delphenidin, petunidin, cyanidin, malvidin, and peonidin in the hydrolyzed grape extracts were included in the quantification study. The validation of this method showed that the recovery percentages of five anthocyanidins ranged from 98.59 % to 103.20% with the relative standard deviation (RSD) less than 5.03%. The qualitative method provided complete insight into the composition of polyphenols in grapes, and other grape-derived products. This quantitative method provides a rapid and accurate tool to quantitatively study individual anthocyanidin in grapes or grape juice samples for quality control and to facilitate the evaluation and comparison of new commercial grapes or grape juice products in market.M.S.Includes bibliographical referencesby Yanping X
评论性翻译: 性别和家庭暴力法（部分）
No full textCon el desarrollo de la civilización humana, cada vez hay más personas que se
preocupan por el problema social relacionado con la violencia de género y doméstica, y se
esfuerzan sin descanso por luchar contra dicha violencia con el fin de eliminarla de raíz. Los
gobiernos también han introducido disposiciones legales para proteger a las víctimas de la
violencia prevista. En particular, el Gobierno español ha elaborado un código integral sobre
dicho tema para que los interesados en la legislación de este ámbito jurídico puedan consultarlo
y utilizarlo.
El objetivo principal del presente estudio es llevar a cabo una traducción comentada del
Código de violencia de género y doméstica (parcial) de España. En dicho estudio, la autora
estudia las teorías de traducción y analiza el texto origen y el texto meta, así como prepara los
recursos de apoyo. Luego estudia y categoriza las dificultades encontradas en el proceso de
traducción y propone soluciones que puedan mejorar la calidad y eficiencia de traducción. El
texto para la traducción comentada es asignado por la facultad y cuenta con 40 páginas.
Contiene el Convenio del Consejo de Europa sobre la violencia de género y doméstica, así
como las disposiciones legales de la Constitución española y de la Ley Orgánica en relación
con este tema.
Por último, se espera que este trabajo pueda servir de inspiración en el futuro a los
profesores y estudiantes que trabajan en este campo, y contribuir al desarrollo del estudio sobre

Comparative studies on OLED performances of chloro and fluor substituted Zn(II) 8-hydroxyquinolinates
No full textTwo novel 8-hydroxyquinoline metallic derivatives, (E)-2-[(2,3,4,5-tetrafluorophenyl)ethenyl]-8-hydroxyquinolate zinc (5) and (E)-2-[2-(2,6-dichlorophenyl]ethenyl]-8-hydroxyquinolate zinc (6) were synthesized and characterized by H-1 NMR, ESI-MS, FT-IR and elemental analysis. Photoluminescence spectra revealed that the complexes showed strong fluorescence with maximum emissions at 575 and 607 nm. Compared with that of complex 5, the fluorescence quantum yield and average fluorescence lifetime of complex 6 were efficiently reduced. The heavy atom effect of Cl and distinct molecular interactions were found to play an important role in modulating or improving the properties of the complexes. Multilayer organic light-emitting diodes (OLEDs) were fabricated using these complexes. The results show they are good candidates for yellow OLEDs with maximum luminance of 7123 cd m(-2) for compound 5 and 9143 cd m(-2) for compound 6, as well as luminance efficiencies of 2.26 cd A(-1) and 2.60 cd A(-1), respectively. As the substituents are changed from fluorine to chlorine, the organic electroluminescent device based on the complex 6 shows overall better performance than that of complex 5. The calculated HOMO-LUMO energy gaps for complexes 5 and 6 were in good agreement with the experimental results

Edge-unfolding almost-flat convex polyhedral terrains
No full textThesis (M. Eng.)--Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2013.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 97-98).In this thesis we consider the centuries-old question of edge-unfolding convex polyhedra, focusing specifically on edge-unfoldability of convex polyhedral terrain which are "almost at" in that they have very small height. We demonstrate how to determine whether cut-trees of such almost-at terrains unfold and prove that, in this context, any partial cut-tree which unfolds without overlap and "opens" at a root edge can be locally extended by a neighboring edge of this root edge. We show that, for certain (but not all) planar graphs G, there are cut-trees which unfold for all almost-at terrains whose planar projection is G. We also demonstrate a non-cut-tree-based method of unfolding which relies on "slice" operations to build an unfolding of a complicated terrain from a known unfolding of a simpler terrain. Finally, we describe several heuristics for generating cut-forests and provide some computational results of such heuristics on unfolding almost-at convex polyhedral terrains.by Yanping Chen.M.Eng
