Hyperbranched polymers containing oxazoline monomers andsuccinic anhydride: applications in fast drying, low solvent coating formulations

tMelt-polycondensation of succinic acid anhydride with oxazoline-based diol monomers gave hyper-branched polymers with carboxylicacids terminal groups.1H NMR and quantitative13C NMRspectroscopy coupled with DEPT-13513C NMR experiment showed high degrees of branching (over 60%).Esterification of the acid end groups by addition of citronellol at 160◦C produced novel white spirit solubleresins which were characterized by Fourier transform-infrared (FTIR) spectroscopy, gel permeation chro-matography (GPC), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Blendsof the new hyperbranched materials with commercial alkyd resins resulted in a dramatic, concentrationdependent drop in viscosity. Solvent-borne coatings were formulated containing the hyperbranchedpolymers. Dynamic mechanical analysis studies revealed that the air drying rates of the new coatingsystems were enhanced compared with identical formulations containing only commercial alkyd resins.

Advances in Discourse Studies

Methods of approaching the study of discourse have developed rapidly in the last ten years, influenced by a growing interdisciplinary spirit among linguistics and anthropology, sociology, cognitive and cultural psychology and cultural studies, as well as among established sub-fields within linguistics itself. Among the more recent developments are an increasing ‘critical’ turn in discourse analysis, a growing interest in historical, ethnographic and corpus-based approaches to discourse, more concern with the social contexts in which discourse occurs, the social actions that it is used to take and the identities that are constructed through it, as well as a revaluation of what counts as ‘discourse’ to include multi-modal texts and interaction. Advances in Discourse Studies brings together contributions from leading scholars in the field, investigating the historical and theoretical relationships between new advances in discourse studies and pointing towards new directions for the future of the discipline. Featuring discussion questions, classroom projects and recommended readings at the end of each section, as well as case studies illustrating each approach discussed, this is an invaluable resource for students of interdisciplinary discourse analysis.

‘Rapt up with joy’: children’s emotional responses to death in early modern England

The chapter is an investigation of the child’s emotional response to death in early modern England. While much valuable scholarship has been produced on parents’ responses to the deaths of children, the reactions of the young themselves have rarely been explored. Drawing on a range of printed and archival sources, I argue that children expressed diverse and conflicting emotions, from fear and anxiety, to excitement and ecstasy. By exploring the emotional experiences of Protestants, the chapter contributes to the bourgeoning literature on emotion and religion, and contests earlier depictions of reformed Protestantism as an inherently intellectual, rather than an affective, faith. This study also suggests that we revise the way we classify the emotions, resisting the intuitive urge to categorise them as ‘positive’ or ‘negative’. The fear of hell, for example, though profoundly unpleasant, was regarded as a rational, commendable response, which demonstrated the work of the Holy Spirit in the soul, and was a prerequisite for the attainment of a joyful assurance of heaven. An underlying question is to what extent children’s responses to death differed from those of adults. I propose that although their reactions were broadly similar, the precise preoccupations of dying children were different. Through highlighting these distinctive features, we can come to a closer idea of what it was like to be a child in the early modern period.

ON AMINO ACID AND CODON ASSIGNMENT IN ALGEBRAIC MODELS FOR THE GENETIC CODE

We give a list of all possible schemes for performing amino acid and codon assignments in algebraic models for the genetic code, which are consistent with a few simple symmetry principles, in accordance with the spirit of the algebraic approach to the evolution of the genetic code proposed by Hornos and Hornos. Our results are complete in the sense of covering all the algebraic models that arise within this approach, whether based on Lie groups/Lie algebras, on Lie superalgebras or on finite groups.

Multivariate Analysis for the Classification Differentiation of Brazilian Sugarcane Spirits by Analysis of Organic and Inorganic Compounds

Brazilian sugarcane spirits were analyzed to elucidate similarities and dissimilarities by principal component analysis. Nine aldehydes, six alcohols, and six metal cations were identified and quantified. Isobutanol (LD 202.9 mu gL-1), butiraldehyde (0.08-0.5 mu gL-1), ethanol (39-47% v/v), and copper (371-6068 mu gL-1) showed marked similarities, but the concentration levels of n-butanol (1.6-7.3 mu gL-1), sec-butanol (LD 89 mu gL-1), formaldehyde (0.1-0.74 mu gL-1), valeraldehyde (0.04-0.31 mu gL-1), iron (8.6-139.1 mu gL-1), and magnesium (LD 1149 mu gL-1) exhibited differences from samples.

Evaluation of a carbon paste electrode modified with organofunctionalised SBA-15 nanostructured silica in the simultaneous determination of divalent lead, copper and mercury ions

The performance of a carbon paste electrode (CPE) modified with SBA-15 nanostructured silica organofunctionalised with 2-benzothiazolethiol in the simultaneous determination of Pb(II), Cu(II) and Hg(II) ions in natural water and sugar cane spirit (cachaca) is described. Pb(II), Cu(II) and Hg(II) were pre-concentrated on the surface of the modified electrode by complexing with 2-benzothiazolethiol and reduced at a negative potential (-0.80 V). Then the reduced products were oxidised by DPASV procedure. The fact that three stripping peaks appeared on the voltammograms at the potentials of -0.48 V (Pb2+), -0.03 V (Cu2+) and +0.36 V (Hg2+) in relation to the SCE, demonstrates the possibility of simultaneous determination of Pb2+, Cu2+ and Hg2+. The best results were obtained under the following optimised conditions: 100 mV pulse amplitude, 3 min accumulation time, 25 mV s(-1) scan rate in phosphate solution pH 3.0. Using such parameters, calibration graphs were linear in the concentration ranges of 3.00-70.0 x 10(-7) mol L-1 (Pb2+), 8.00-100.0 X 10(-7) mol L-1 (Cu2+) and 2.00-10.0 x 10(-6) mol L-1 (Hg2+). Detection limits of 4.0 x 10(-8) mol L-1 (Pb2+), 2.0 x 10(-7) mol L-1 (Cu2+) and 4.0 x 10(-7) mol L-1 (Hg2+) were obtained at the signal noise ratio (SNR) of 3. The results indicate that this electrode is sensitive and effective for simultaneous determination of Pb2+, Cu2+ and Hg2+ in the analysed samples. (C) 2008 Published by Elsevier B.V.

Chemical profile of rums as a function of their origin. The use of chemometric techniques for their identification

To identify chemical descriptors to distinguish Cuban from non-Cuban rums, analyses of 44 samples of rum from 15 different countries are described. To provide the chemical descriptors, analyses of the the mineral fraction, phenolic compounds, caramel, alcohols, acetic acid, ethyl acetate, ketones, and aldehydes were carried out. The analytical data were treated through the following chemometric methods: principal component analysis (PCA), partial least square-discriminate analysis (PLS-DA), and linear discriminate analysis (LDA). These analyses indicated 23 analytes as relevant chemical descriptors for the separation of rums into two distinct groups. The possibility of clustering the rum samples investigated through PCA analysis led to an accumulative percentage of 70.4% in the first three principal components, and isoamyl alcohol, n-propyl alcohol, copper, iron, 2-furfuraldehyde (furfuraldehyde), phenylmethanal (benzaldehyde), epicatechin, and vanillin were used as chemical descriptors. By applying the PLS-DA technique to the whole set of analytical data, the following analytes have been selected as descriptors: acetone, sec-butyl alcohol, isobutyl alcohol, ethyl acetate, methanol, isoamyl alcohol, magnesium, sodium, lead, iron, manganese, copper, zinc, 4-hydroxy3,5-dimethoxybenzaldehyde (syringaldehyde), methaldehyde (formaldehyde), 5-hydroxymethyl-2furfuraldehyde (5-HMF), acetalclehyde, 2-furfuraldehyde, 2-butenal (crotonaldehyde), n-pentanal (valeraldehyde), iso-pentanal (isovaleraldehyde), benzaldehyde, 2,3-butanodione monoxime, acetylacetone, epicatechin, and vanillin. By applying the LIDA technique, a model was developed, and the following analytes were selected as descriptors: ethyl acetate, sec-butyl alcohol, n-propyl alcohol, n-butyl alcohol, isoamyl alcohol, isobutyl alcohol, caramel, catechin, vanillin, epicatechin, manganese, acetalclehyde, 4-hydroxy-3-methoxybenzoic acid, 2-butenal, 4-hydroxy-3,5-dimethoxybenzoic acid, cyclopentanone, acetone, lead, zinc, calcium, barium, strontium, and sodium. This model allowed the discrimination of Cuban rums from the others with 88.2% accuracy.

Formation of Dextran Deposits in Brazilian Sugar Cane Spirits

The formation of dextran deposits in sugared Brazilian cachaca was studied as a function of the time considering the effects of temperature, molecular weight (M(w)), visible light, pH, and the presence of Ca, Mg, Cu, and Fe ions in the concentrations at which they are usually present in this beverage. At 25 degrees C and pH 4.4, the experimental half-lives (t(1/2)) for precipitation are 73 and 124 days for dextrans with M(w) 5.9 x 10(6) and 2.1 x 10(6) Da, respectively. For dextrans with M(w) 5.0 x 10(5) and 4.0 x 10(4) Da, the experimental t(1/2) values are >180 days. For a dextran with M(w) 2.1 x 10(6) Da a change in pH from 4.4 to 5.5 at 25 degrees C resulted in a t(1/2) decrease from 124 to 25 days. At pH 4.4 the visible light and the presence of metal ions in average concentrations usually found in cachacas do not exhibit noticeable influence on the rate of dextran precipitation.

Molecular mass distribution of dextran in Brazilian sugar and insoluble deposits of cachaca

The dextran molecular mass distribution profile in 77 sugar samples from Brazil and twelve insoluble deposits (alcoholic flocks) samples from sugared cachacas (Brazilian sugar cane spirit) is described in terms of number-average molecular mass M,,, weight-average molecular mass M(w), Z-average molecular mass M,, and polydispersity. The analyses were performed by size-exclusion chromatography, using a refractive index detector. In most of the sugar samples, it was possible to identify two major groups of dextrans with Mw averages of 5 x 10(6) and 5 x 10(4) Da. Based on the evaluated parameters, the dextran distribution profile is about the same in samples analyzed over five seasons, and, therefore, it is likely that the Brazilian product pattern will not change very much over the years. In insoluble deposits from sugared cachacas, dextrans with Mw values in the order of the 10(5) Da were the most frequent ones, being present in 58% of the samples. (c) 2008 Elsevier Ltd.

L’évolution du français par rapport à l’histoire et en comparaison avec celle du suédois

Une langue est comme un être vivant. Elle porte les traces des avis, des sentiments, de la joie et des déceptions de nos ancêtres. En même temps elle reflète les toutes tous derniers modes de vie et la manière de penser et d’agir dans la vie quotidienne. Ce sont sa grammaire, ses mots, ses proverbes et ses citations qui en témoignent. Ses sons soulignés par l’intonation et la prosodie nous laissent presque deviner l’esprit de vitalité, de mélancolie ou d’élégance de la langue et de ces locuteurs. Mais est-ce qu’il est possible de trouver aussi les traces des événements historiques et sociaux dans l’évolution d’une langue? Cette question est centrale dans ce mémoire qui suit l’évolution du français à partir du latin parlé dans l’Antiquité et en comparaison avec celle d’autres langues notamment celle du suédois.

Glädje i vårdandets värld

Föreliggande vårdvetenskapliga studie har som syfte att avtäcka och synliggöra glädjesom idé i vårdandets värld. Glädje sammanbinds med vårdandet genom kärleken somden tongivande kraften hos glädje. Vårdandets sak har genom historien alltid varit attlindra lidande och att tjäna liv och hälsa i en anda av kärlek och barmhärtighet. Dennastudie om glädje i vårdandet har en övergripande idéhistorisk inriktning och resultatetsammanställs i form av ett idémönster. Tolkningen sker genom en hermeneutisk ansatsmed fokus på förståelse av själva vårdandet. För att djupare förstå glädje, dessursprungsidé, väsen och uttrycksformer granskas begreppet ’glädje’ och de näraliggandebegreppen ’glad’ och ’ljus’ i etymologiska ordböcker samt i svenska, engelska ochlatinska ordböcker. Som stöd för tolkningen används klassiska texter innehållandefilosofers tankar om glädje. Glädje som idé glimtar fram i form av ett sjufaldigtmönster. Detta mönster innehåller särdrag hos glädje och det hjärtas natur somrespektive särdrag förverkligas i. I andlig mening utgör hjärtat livets medelpunkt ochkänslornas hemvist. Mönstret bildar bakgrund och blir vägledande vid den hermeneutiska läsningen omglädje, så som den framträder i berättelser om vårdande under åren 1900–1933. Dehistoriska källorna utgörs av facktidskriften Svensk sjukskötersketidning, böcker medberättelser om vårdande, arkivmaterial samt läroböcker om vårdarbete. Resultatetmynnar ut i ett idémönster, där idéer om det som gör glädje verksamt som vårdandeframträder. Dessa är det sanna hjärtats rena glädje – kärlek, glädje är ett kärleksbevis.Det brinnande hjärtats djupa glädje – livsglädje, glädje inspirerar och genererar kraft.Det bärande hjärtats glansfulla glädje – generositet, glädje är en gåva till den andra medlöfte om hjälp. Det inbjudande hjärtats glittrande glädje – gemenskap, glädje inbjudertill gemenskap. Det upprymda hjärtats uppsluppna glädje – integration, glädje gör attmänniskan kan glömma sitt lidande och närma sig den hon önskar vara. Detstämningsfulla hjärtats högtidliga glädje – bevärdigande, glädje skapar en anda ochatmosfär där människan upplever sig hedrad. Det fridfulla hjärtats stora glädje –räddning, en glädje visar sig när människan har erhållit det som kan begäras av gott ochundsluppet ont och är förnöjd med sin levnads lott. Förhoppningen är att dennagrundforskning ska öppna för ett nytt seende som kan leda till att glädjeuppmärksammas i vårdandets värld och artikuleras där.

La picaresca en Mortadelo y Filemón

Mort and Phil (Mortadelo y Filemón) are one of the most famous Spanish comics in thehistory. As some of the characters of Spanish comic they have been sometimes described aspicaresque. The objective of our study is finding out if Mort and Phil play the role of thepicaro. Our study follows the hermeneutic method, taking into consideration the role of thecomic in Spanish society and the concept of picaresque novel. In order to carry out theanalysis, we will look for the characteristics of the picaresque in three stories of theadventures of Mort and Phil. Along the study we will notice the lack of consensus in order todecide what it can be considered a picaresque novel or what not besides showing allcharacteristics of picaresque are not present in this comic. Therefore, we conclude that Mortand Phil can not be considered a picaresque novel but it could be understood as a work ofpicaresque spirit.

”Tacksamhet för att jag fick ett nytt liv” : En kvalitativ studie om återanpassningsstrategier efter avtjänat fängelsestraff

Intresset för kriminalitet och individerna bakom de kriminella handlingarna ökar i samhället och återges i media dagligen. Det är just individen bakom brottet, hen som fängslas och får avtjäna sitt straff som denna studie riktar sitt fokus på. När fängelsegrindarna öppnas och återinträdet till samhället blir ett faktum; Hur tar då dessa individer sig tillbaka till samhället för att åter bli en del av det? Syftet med denna studie är att undersöka vilka återanpassningsstrategier som frigivna använder sig av samt hur samhällets bemötande påverkar strategierna. Studien baseras på självbiografier skrivna av fyra författare som alla levt ett kriminellt liv och som sedermera avtjänat ett eller flera fängelsestraff. Resultatet visar att det finns flera anpassningsstrategier som tas i bruk. Däribland att söka hjälp och stöd hos familj, vänner eller andra sociala grupper. Vidare återfinns det i strävan efter en ”ny identitet” vilket ofta sker med hjälp av tro. Att sysselsätta sig, ge något tillbaka till samhället, visa sin kreativitet i syfte att återfå sin kredibilitet kan ses som strategier som leder fram till det slutliga målet, kredibiliteten. Slutligen kunde ett samband mellan samhällets bemötande och återanpassningsstrategierna utrönas. Ju mer negativt bemötandet är desto fler återanpassningsstrategier behövs och arbetet för att uppnå dem blir mer krävande. Givet blir då att ett bemötande som fyllts av uppmuntran till individens förändring medför att färre strategier behövs och risken för återfall blir mindre.

The relative perceptual weight of two Swedish prosodic contrasts

Abstract. In addition to 9 vowel and 18 consonant phonemes, Swedish has three prosodic phonemic contrasts: word stress, quantity and tonal word accent. There are also examples of distinctive phrase or sentence stress, where a verb can be followed by either an unstressed preposition or a stressed particle. This study focuses on word level and more specifically on word stress and tonal word accent in disyllabic words. When making curriculums for second language learners, teachers are helped by knowing which phonetic or phonological features are more or less crucial for the intelligibility of speech and there are some structural and anecdotal evidence that word stress should play a more important role for intelligibility of Swedish, than the tonal word accent. The Swedish word stress is about prominence contrasts between syllables, mainly signaled by syllable duration, while the tonal word accent is signaled mainly by pitch contour. The word stress contrast, as in armen [´arːmən] ‘the arm’ - armén [ar´meːn] ‘the army’, the first word trochaic and the second iambic, is present in all regional varieties of Swedish, and realized with roughly the same acoustic cues, while the tonal word accent, as in anden [´anːdən] ‘the duck’ - anden [`anːdən] ‘the spirit��� is absent in some dialects (as well as in singing), and also signaled with a variety of tonal patterns depending on region. The present study aims at comparing the respective perceptual weight of the two mentioned contrasts. Two lexical decision tests were carried out where in total 34 native Swedish listeners should decide whether a stimulus was a real word or a non-word. Real words of all mentioned categories were mixed with nonsense words and words that were mispronounced with opposite stress pattern or opposite tonal word accent category. The results show that distorted word stress caused more non-word judgments and more loss, than distorted word accent. Our conclusion is that intelligibility of Swedish is more sensitive to distorted word stress pattern than to distorted tonal word accent pattern. This is in compliance with the structural arguments presented above, and also with our own intuition.
