TL;DR: The use of meta-chloroperbenzoic acid (mCPBA) for organic synthesis has been extensively studied as mentioned in this paper, and it is widely used for chemical transformations such as the oxidation of carbonyl compounds, iminoindolines, olefins, imines, alkanes, silyl enol ethers, N- and S-heterocycles, active methylene groups, fluoromethylated allylic bromides, cyclic acetals, selenides, furans and phosphates.
Abstract: The synthetic uses of different peroxides for organic synthesis have been widely studied. Among these peroxides, meta-chloroperbenzoic acid (mCPBA) is an efficient oxidizing reagent and have been used for many oxidative transformations. mCPBA is widely used for chemical transformations such as the oxidation of carbonyl compounds, iminoindolines, olefins, imines, alkanes, silyl enol ethers, N- and S-heterocycles, active methylene groups, fluoromethylated allylic bromides, cyclic acetals, N-substituted phthalimidines, selenides, furans and phosphates. The purpose of this review is to collect and discuss the synthetic applications of meta-chloroperbenzoic acid (mCPBA) over the past few decades.

TL;DR: The EsKiMo (Ernahrungsstudie als KiGGS-Modul) study as mentioned in this paper was conducted by the Robert Koch-Institut (RKI) gemeinsam with der Universitat Paderborn.
Abstract: Im Rahmen des bundesweiten Kinder- und Jugendgesundheitssurveys (KiGGS) wurde von Januar bis Dezember 2006 in einem Modul das Ernahrungsverhalten von 6- bis 17-Jahrigen erfasst. Die Studie mit dem Namen EsKiMo (Ernahrungsstudie als KiGGS-Modul) wurde vom Robert Koch-Institut (RKI) gemeinsam mit der Universitat Paderborn, Fachgruppe Ernahrung und Verbraucherbildung, durchgefuhrt und vom Bundesministerium fur Ernahrung, Lebensmittel und Verbraucherschutz finanziert. Die Eltern der teilnehmenden Kinder unter 12 Jahren wurden gebeten, gemeinsam mit ihrem Kind ein 3-Tage-Verzehrsprotokoll zu fuhren. Die alteren Kinder wurden personlich mit Hilfe von DISHES (Dietary Interview Software for Health Examination Studies) zu ihrer Ernahrung in den letzten 4 Wochen befragt. Auserdem sollten sie einen bereits im KiGGS eingesetzten Ernahrungsfragebogen (Food Frequency Questionnaire) ein zweites Mal ausfullen. Zusatzlich kam bei allen Teilnehmern ein Kurzfragebogen zum Einsatz, in dem unter anderem soziodemographische Daten, Aspekte der Freizeitgestaltung, Supplementeinnahme, Verpflegung in der Schule sowie Korpergrose und -gewicht erhoben wurden. Die Studie wird aktuelle, reprasentative Daten zur Ernahrung von Kindern und Jugendlichen in Deutschland liefern. Diese werden sowohl hinsichtlich der Lebensmittelverzehrsmengen als auch Nahrstoffversorgung ausgewertet. Durch die Verbindung der Ernahrungsdaten mit den im KiGGS erhobenen Gesundheitsdaten sind auserdem umfangreiche Analysen zum Zusammenhang zwischen Ernahrung und Gesundheit moglich.

TL;DR: In this article, a self-consistent charge density-functional based tight-binding method was used to describe small gold clusters, and the method correctly reproduces the planarity of ground-state structures up to cluster sizes in agreement with experiment and density functional theory.
Abstract: In this paper, we report the ability of self-consistent-charge density-functional based tight-binding method to describe small gold clusters. We concentrate our investigations mainly on anions, and find that the method describes their geometric and electronic structures fairly well, in comparison with density-functional calculations. In particular, the method correctly reproduces the planarity of ground-state structures up to cluster sizes in agreement with experiment and density-functional theory.

TL;DR: In this article, the structural phase transitions and fundamental band gaps of MgxZn1�xO alloys are investigated by detailed first-principles calculations in the entire range of mg concentrations x, applying a multiple-scattering theoretical approach.
Abstract: Received 29 April 2009; revised manuscript received 27 June 2009; published 6 October 2009 The structural phase transitions and the fundamental band gaps of MgxZn1�xO alloys are investigated by detailed first-principles calculations in the entire range of Mg concentrations x, applying a multiple-scattering theoretical approach Korringa-Kohn-Rostoker method Disordered alloys are treated within the coherentpotential approximation The calculations for various crystal phases have given rise to a phase diagram in good agreement with experiments and other theoretical approaches The phase transition from the wurtzite to the rock-salt structure is predicted at the Mg concentration of x = 033, which is close to the experimental value of 033–040 The size of the fundamental band gap, typically underestimated by the local-density approximation, is considerably improved by the self-interaction correction The increase in the gap upon alloying ZnO with Mg corroborates experimental trends Our findings are relevant for applications in optical, electrical, and, in particular, in magnetoelectric devices

TL;DR: In this paper, it was shown that if n ≤ 5, then for all suitably regular initial data an associated no-flux initial-boundary value problem admits a global weak solution, which is the first result on global existence in a system of the form (⋆) in a spatially three-dimensional setting when arbitrarily large initial data and parameters are involved.
