Structure-based engineering of strictosidine synthase: auxiliary for alkaloid libraries.
2007
SummaryThe highly substrate-specific strictosidine synthase (EC 4.3.3.2) catalyzes the biological Pictet-Spengler condensation between tryptamine and secologanin, leading to the synthesis of about 2000 monoterpenoid indole alkaloids in higher plants. The crystal structure of Rauvolfia serpentina strictosidine synthase (STR1) in complex with strictosidine has been elucidated here, allowing the rational site-directed mutation of the active center of STR1 and resulting in modulation of its substrate acceptance. Here, we report on the rational redesign of STR1 by generation of a Val208Ala mutant, further describing the influence on substrate acceptance and the enzyme-catalyzed synthesis of 10-m…
Evaluation and Accreditation System of External Internship Tutors - SEATPE
2020
La Universidad de Valencia ha implementado desde 2012 un Sistema de Evaluación y Acreditación de Tutores de Pasantías Externas (SEATPE) a través de su Fundación Universidad-Empresa, ADEIT, bajo la dirección del Vicerrector de Empleo y Programas Formativos. Los objetivos principales de este sistema son mejorar la calidad de la tutoría de pasantías externas implementando mecanismos para reconocer el buen trabajo de los tutores y aumentar el compromiso de las empresas y entidades con la capacitación práctica de nuestros estudiantes. Está dirigido a los dos perfiles de tutores: académicos y empresas. Los tutores que acceden al SEATPE obtienen una "Mención de calidad" en el caso del tutor académ…
Morphometrics of Second Iron Age ceramics - strengths, weaknesses, and comparison with traditional typology.
2014
12 pages; International audience; Although the potential of geometric morphometrics for the study of archaeological artefacts is recognised, quantitative evaluations of the concordance between such methods and traditional typology are rare. The present work seeks to fill this gap, using as a case study a corpus of 154 complete ceramic vessels from the Bibracte oppidum (France), the capital of the Celtic tribe Aedui from the Second Iron Age. Two outline-based approaches were selected: the Elliptic Fourier Analysis and the Discrete Cosine Transform. They were combined with numerous methods of standardisation/normalisation. Although standardisations may use either perimeter or surface, the res…
Profiling Major Sport Event Visitors: The 2002 Commonwealth Games
2007
It has become common practice for governments and municipalities around the world to bid for the right to host a major sporting event. Prior to embarking on the bidding process, politicians attempt to determine whether such an event will be of value to their municipality; and often focus on the estimated economic consequences of hosting such an event. Frequently, studies are commissioned to predict the event's economic value. However, these studies often miscalculate the potential impact of sport event visitors as consumers. We argue that enhanced profiling of these visitors will enable a more accurate assessment of economic impact. The current research surveys 1,196 spectators of the 2002 …
Framework for Evaluating the Version Management Capabilities of a Class of UML Modeling Tools from the Viewpoint of Multi-site, Multi-partner Product…
2009
UML models are widely used in software product line engineering for activities such as modeling the software product line reference architecture, detailed design, and automation of software code generation and testing. But in high-tech companies, modeling activities are typically distributed across multiple sites and involve multiple partners in different countries, thus complicating model management. Today’s UML modeling tools support sophisticated version management for managing parallel and distributed modeling. However, the literature does not provide a comprehensive set of industrial-level criteria to evaluate the version management capabilities of UML tools. This article’s contributio…
Sobre el «marc de condicions sociolingüístiques favorables» per a la implantació de la normativa lingüística
2016
Resum: Aquest treball pretén desplegar conceptualment la unitat lèxica marc de condicions sociolingüístiques favorables proposada per F. X. Vila, M. Nogué i I. Vila a fi que sigui acadèmicament operativa per analitzar quins són els factors que afavoririen la implantació de la normativa. Per fer-ho partirem, entre altres, d’una concepció àmplia de la «sociolingüística catalana» i de treballs nostres. A partir d’aquesta concepció, analitzarem quins factors podrien afavorir la implantació de la normativa. I ho farem seguint les fases que normalment segueix la implantació de les normes: codificació (incloent-hi la selecció), difusió, i implantació o no implantació. Dins de cada una de les fases…
Evaluation of caries risk in a young adult population
2007
Introduction: Various caries risk prediction models have been developed in recent years. Cariogram®, a software program that evaluates an individual’s caries risk profile and illustrates it in graphic form, appears to classify patients more correctly than other risk prediction methods. Objectives: The objective of this study was to determine the caries risk of a population by means of the Cariogram® software and examine the relationships between the different variables used by the Cariogram® and the risk of caries determined by this program. Materials and Methods: Data were collected from a sample of 48 young individuals by clinical and radiological examination, saliva sampling and a dietar…
Attitudes toward technological resources in the classroom of the future teachers
2015
The aim of this study is to analyze attitudes future teachers towards technological resources in the classroom. We have considered three dimensions for analysis, the practice in the classroom, student learning and the valuation that future teachers as make their own attitude technological resources. For the statistical analysis used descriptive techniques; t test for comparison of independent groups, and univariate analysis of covariance (ANOVA). The results indicate that attitudes is positive, but we can see that there are some significant differences in gender respects to some of the issues raised.
Mechanical evaluation for three-dimensional printed orthodontic springs with different heights-in vitro study
2021
Background The orthodontic spring materials in use have a significant influence on the applied forces. The prerequisite to identify the in vitro< force deflection of the CAD/CAM fabricated springs is considered mandatory to identify the material characteristics. The purpose of the present investigation was to evaluate the mechanical load on 3D printed springs using different coil heights. Material and Methods The springs were digitally designed with different coil heights using Autodesk Netfabb CAD software (San Rafael, CA, USA). Test specimens were manufactured using 3D printable experimental flexible material (Code: BM2008, GC, Tokyo, Japan). The specimens were divided according to the co…
Shear force comparative evaluation for surface treated and non- treated 3D interim printed materials with different types of glass-ionomer cements
2020
Background The purpose of this investigation was to compare shear force of different glass-ionomer cements on 3D printed interim material in combination with and without surface pretreatment. Material and Methods 120 rectangular specimens made of printable provisional material (Bego, Bremen, Germany) were used. After post-processing the specimens were blasted with aluminum oxide 110µm (Bego, Bremen, Germany). Extra 120 non-surface treated specimens were used as an experimental negative test group. All 240 specimens were divided randomly into 6 groups. All were cemented with a compressive load of 20 N using universal testing machine Z010 (Zwick/Roell, Ulm, Germany) to ensure a comparable cem…
