Abstract Although a number of plant natural products are derived from benzoic acid, the biosynthesis this structurally simple precursor is poorly understood. Hypericum calycinum cell cultures accumulate acid-derived xanthone phytoalexin, hyperxanthone E, in response to elicitor treatment. Using subtracted complementary DNA (cDNA) library and sequence information about conserved coenzyme A (CoA) ligase motifs, cDNA encoding cinnamate:CoA (CNL) was isolated. This enzyme channels metabolic flux...
The torsional stiffness of I-beams with sinusoidal corrugated web is higher than that flat beams and the accuracy available hand-calculation methods to determine elastic critical lateral-torsional buckling moment depends on geometrical parameters beam corrugation. This study proposes different machine learning models moments beams. Various machine-learning algorithms such as Decision Tree, Random Forests, Gradient Boosting, Support Vector Regression, Catboost, Deep Neural Network were...
Paul de Faget Casteljau (19.11.1930 - 24.3.2022) has left us an extensive autobiography, written in 1997. In 19 sections, he takes through his eventful life which describes with wit and humor. We read about youth occupied France education at the Ecole Normale Supérieure. He detail various episodes from time Citroën, situation during after discovery of now famous algorithm, takeover by Peugeot, ban working on CAD corporate rehabilitation thanks to advances polar forms quaternions. His memoirs...
In plants, prenylation of metabolites is widely distributed to generate compounds with efficient defense potential and distinct pharmacological activities profitable human health. Prenylated are formed by members the prenyltransferase (PT) superfamily, which catalyze addition prenyl moieties a variety acceptor molecules. Cell cultures Hypericum calycinum respond elicitor treatment accumulation prenylated xanthone hyperxanthone E. A cDNA encoding membrane-bound PT (HcPT) was isolated from...
The required operating range for hydraulic machines is continually extended in an effort to integrate renewable energy sources with unsteady power outputs into the existing electrical grid. off-design operation however brings forth unfavorable flow patterns machine, causing dynamic problems involving cavitation, which may represent a limiting factor production. In Francis turbines it observed that self-excited oscillation of vortex rope draft tube cone prevents delivery maximum when...
Whilst Paul de Casteljau is now famous for his fundamental algorithm of curve and surface approximation, little known about other findings. This article offers an insight into results in geometry, algebra number theory. Related to classical reviewed as index reduction a polar form. idea used show Casteljau's algebraic way smoothing, which long went unnoticed. We will also see analytic form its use finding the intersection two curves. The summarises unpublished material on metric geometry. It...
Due to the penetration of alternative renewable energies, stabilization electrical power network relies on off-design operation turbines and pump-turbines in hydro-power plants. The occurrence cavitation is however a common phenomenon at such operating conditions, often leading critical flow instabilities which undercut grid stabilizing capacity plant. In order predict extend stable range hydraulic machines, better understanding cavitating flows mainly transition between unstable regimes...
Abstract The traditional separation of analysis and verification during the structural design steel structures is a known source conservatism inaccuracy, as true deformation/rotation capacity sections redistribution internal forces in systems remains only vaguely many cases. This particularly affects made high‐strength steel, since often would need to be classified slender, thus disallowing possibility account for plasticity stress redistribution. Shell‐element FEM‐models with material...
Acoustic resonances in Francis turbines often define undesirable limitations to their operating ranges at high load. The knowledge of the mechanisms governing onset and sustenance these instabilities swirling flow leaving runner is essential for development a reliable hydroacoustic model prediction system stability. present work seeks study experimentally unstable draft tube by conducting series measurements on reduced Turbine model. key physical parameters interaction with hydraulic...
Purpose The purpose of this study is to investigate the effects city brand benefits (cost efficiency, job chances, social life, recreation and self–brand connection) on highly skilled, potential residents’ attitudes toward brand. Design/methodology/approach A literature analysis qualitative inform a conceptual model, which tested with structural equation modelling using 354 evaluations six largest German cities by 294 residents, in terms their perceptions attitudes. Findings Social life...

Der Artikel greift die Frage nach den Zielen und der Gestaltung von Prüfungen vor dem Hintergrund veränderten Anforderungen in modularisierten Studiengängen auf. Dabei wird für Herstellung einer Passung zwischen Lernzielen, Lehrmethoden Prüfungsformen plädiert auf lehrer- wie lernerzentrierten Lernarrangements eingegangen. Aus hochschuldidaktischer Perspektive verdeutlicht, welche - bisher noch wenig oder nur rudimentär genutzten Chancen Konzepten des peer- self-assessment Settings ausgehen....
Une réforme en cours au Sénégal privatise la gestion de l’eau des forages pastoraux du Ferlo ; les pasteurs quant à eux gèrent leurs ressources naturelles, eau et pâturages, d’une manière intégrée accommodant divers principes d’accès. Au-delà aménagements locaux imposés comptable, cet article montre quelles règles dominent structurent l’organisation sociale infrastructures. Mais cette pluralité logiques ne se révélerait-elle pas aussi, sous d’autres configurations, dans sociétés plus...
