description: The clayey quarry fines (QF), coming from aggregate washing processes, are mixed with hemp straw (HS) to make non-bearing blocks. This study aims to obtain satisfying mechanical performances with interesting comfort characteristics by having blocks easy to handle and to manufacture. The study shows that mixes with only quarry fines and hemp straw give low mechanical performances. To enhance these results, lime and a superplasticizer are added in the mix design. By keeping a major proportion of quarry fines, the obtained mix offers mechanical strengths similar to performances of market products (gypsum blocks, cellular concrete blocks) and having interesting thermal and acoustic characteristics.

description: Soluble wall proteins from Vitis vinifera pollen are genotypically determined and their expression, if not the extent of their expression, is independent from external factors. After we had previously observed that the time of sample collection does not influence their electrophoretic pattern, we demonstrate in the present work that this is true also for environment where the vine is growing and for the rootstock on which the scion is grafted.

description: Epidermal cells of Vitis cvs attacked by powdery mildew or damaged mechanically exhibited silica deposits in the walls of the attacked and surrounding cells. Entire or parts of cell walls were vitrified to such an extent that pure, mechanically resistant silica skeletons remained after a treatment with conc. H2S04 + H2O2 at 400 °C and washing with conc. HCl. They consisted of groups of 1-20 cells of the upper epidermis with adhering parts of the corresponding palisade cells or of the lower epidermis (including stomatal cells) with adhering spongy parenchyma. Not only cell walls but also wrinkles of the upper epidermis, defense papillae and fungal haustoria were silicified. Silica accumulations were greater in resistant than in susceptible cultivars.

description: Το προτεινόμενο σύγγραμμα πραγματεύεται τη μελέτη των Πλανητικών Συστημάτων (και βέβαια του ηλιακού συστήματος), η οποία αποτελεί πλέον ένα από τα πλέον σύγχρονα ερευνητικά αντικείμενα στο πεδίο της Αστρονομίας-Αστροφυσικής διεθνώς, μετά και από τις συνεχείς ανακαλύψεις νέων, εξω-ηλιακών συστημάτων, αλλά και την ανάπτυξη νέων θεωριών για τη δυναμική εξέλιξη του ηλιακού συστήματος. Το βιβλίο θα περιγράφει αναλυτικά τόσο τα παρατηρησιακά δεδομένα όσο και τη βασική θεωρία σχηματισμού πλανητών και δυναμικής εξέλιξης τέτοιων συστημάτων. Θα απευθύνεται σε προπτυχιακούς φοιτητές (4ου έτους) Φυσικής αλλά θα εμβαθύνει (κατά περίπτωση) σε έννοιες που αποτελούν απαραίτητη γνώση για έναν μεταπτυχιακό φοιτητή που επιθυμεί να ασχοληθεί με το εν λόγω ερευνητικό αντικείμενο. Η σύνδεση της μελέτης των πλανητικών συστημάτων με τις διαστημικές αποστολές θα τονίζεται σε κάθε ευκαιρία.

Η ύλη του βιβλίου καλύπτει την περιγραφή των φυσικών και δυναμικών χαρακτηριστικών των πλανητών και των άλλων σωμάτων του ηλιακού συστήματος (αστεροειδείς, κομήτες) και τις τεχνικές παρατήρησης εξω-πλανητών και την κατηγοριοποίηση των πλανητικών συστημάτων (με βάση τα τροχιακά και φυσικά χαρακτηριστικά τους). Επίσης, καλύπτει τις βασικές έννοιες Ουράνιας Μηχανικής που είναι απαραίτητες για την κατανόηση της δυναμικής, τις βασικές θεωρίες σχηματισμού γήινων και γιγαντιαίων πλανητών, καθώς και τις νεότερες θεωρίες δυναμικής εξέλιξης και μορφοποίησης του ηλιακού συστήματος και των εξω-ηλιακών συστημάτων.

Σημειώνουμε ότι επί του παρόντος δεν υπάρχει αντίστοιχο σύγγραμμα στα Ελληνικά, ενώ μόλις πρόσφατα εισήχθη αντίστοιχο προπτυχιακό μάθημα σε προπτυχιακό πρόγραμμα σπουδών στην Ελλάδα, από τον κύριο συγγραφέα. Επίσης, αξίζει να σημειωθεί ότι είναι η πρώτη προσπάθεια συγγραφής βιβλίου και συστηματικής διδασκαλίας στη χώρα μας, σε θέματα που άπτονται της διαστημικής εξερεύνησης (αποστολές) - παρά το γεγονός ότι η Ελλάδα αποτελεί εδώ και χρόνια μέλος του Ευρωπαϊκού Οργανισμού Διαστήματος (ESA).

description: Uptake and stability of dicyandiamide in grapevines Dicyandiamide (DCD) is taken up as a molecule by the roots and translocated via the stem to the Jeaves within 24 h . 15 d after omitting 14C - DCD from the nutrient solution, it is still found in the Jeaves together with other compounds showing 14C-activity. Over the whole experimental period a certain amount of DCD is detected in the leaves. DCD thus strongly differs from cyanamide which is metabolized in plants within a few hours.

description: Tokar, A., Andreeva, T. I., & Shulga, L. (2014). Social learning and peer education in responding to opiate overdose among injection drug users in Ukraine. Tobacco Control and Public Health in Eastern Europe, 4(1), 29-39. doi: 10.6084/m9.figshare.1064370 BACKGROUND: Opiate overdoses (OD) constitute one of the leading causes of avoidable deaths among people aged 20-40 years old. As peer-administered help in cases of overdose was found to be effective, we aimed to explore how much the subjects of the intervention are able to learn from one another and from their own experience.
METHODS: Secondary data analysis was performed with the 2008 dataset of peer-driven intervention among IDUs who were not involved in harm reduction programs earlier; recruiting was performed with respondent driven sampling methodology combined with peer education covering overdose response. Subsample of 6667 opiate users was considered. Data on overdose response strategies experienced by respondents were considered predictors and data on intended response strategies as outcomes. To reveal relationships between the experienced and intended responses, binary logistic regression analysis was performed.
RESULTS: With recommended strategies including calling ambulance, putting a person in recovery position, fixing the tongue, applying mouth-to-mouth resuscitation and cardiac massage, percentages of those planning to apply them was considerably higher (on average, 2.3 times higher) than the percentage of those having experienced them.
With other strategies including applying cold, pain, ammonia, percentages of those who experienced the strategy and those who planned to practice it were rather close and on average differed just by 1.1.
With all the strategies, the intention to apply a particular response in future was strongly associated with personal experience of having had this applied when having an overdose episode. Peer-education to larger extent determines the intentions of those who have not experienced particular overdose responses themselves. On the other hand, social learning contributes to persisting of those experienced strategies which cannot be recommended.
CONCLUSIONS: Social learning can impact intended overdose responses, its competing interaction with peer-education needs to be taken into account in harm reduction programs.

description: The activity of polyphenol oxidase (PPO) and content of phenolic compounds were followed during the maturation in two varieties of wine grapes grown in south-eastern Spain and during vinification at different sulphur dioxide concentrations. Both cresolase and catecholase activities (measured at pH 7.0 and 4.5, respectively) increased throughout the studied period and the content of phenolic compounds decreased rapidly when expressed as concentration (mg gallic acid/g total fresh weight), while when expressed as total amount per berry (mg/berry) it remained constant. During wine production, the enzyme activity was highest immediately after crushing of the fresh grapes and was not detected at the end of the fermentation process. The phenolic content also decreased during vinification to a constant level depending on the S02 level used.

Differential response of grapevine cultivars to European red mite (Panonychus ulmi KOCH)- elaboration of a screening method
Creators: name: Rilling, G.
Publisher: name: VITIS - Journal of Grapevine Research
Year: 2015

description: Population development of the European red mite, Panonychus ulmi KOCH, was studied in the field on 16 Vitis vinifera cultivars and 5 interspecific crosses. Population frequency could considerably vary between cultivars. A significant positive correlation existed between the density of prostrate (downy) hairs on the lower leaf surface and the. population frequency of P. ulmi. The degree of leaf damage due to feeding of mites was visually estimated according to the extent of leaf discoloration (bronzing). 5 classes of damage were distinguished and scored by the indices 1 (normal colour), 3, 5, 7 and 9 (most advanced discoloration). Among the grapevine genotypes examined, a significant positive correlation between the degree of leaf damage and the population frequency of P. ulmi was stated toward the onset of grape maturity but not earlier in the growing season. Similarly, a positive correlation between density of prostrate hairs and discoloration of infested leaves was observed only later in the growing season. Perspectives of breeding grapevine cultivars which are tolerant to attack by P. ulmi are discussed.

description: Surround-view fisheye cameras are commonly used for near-field sensing in automated driving. Four fisheye cameras on four sides of the vehicle are sufficient to cover 360◦ around the vehicle capturing the entire near-field region. Some primary use cases are automated parking, traffic jam assist, and urban driving. There are limited datasets and very little work on near-field perception tasks as the focus in automotive perception is on far-field perception. In contrast to far-field, surround-view perception poses additional challenges due to high precision object detection requirements of 10cm and partial visibility of objects. Due to the large radial distortion of fisheye cameras, standard algorithms cannot be extended easily to the surround-view use case. Thus, we are motivated to provide a self-contained reference for automotive fisheye camera perception for researchers and practitioners. Firstly, we provide a unified and taxonomic treatment of commonly used fisheye camera models. Secondly, we discuss various perception tasks and existing literature. Finally, we discuss the challenges and future direction.

description: :Objective: This pilot study aimed to investigate physiological responses during an on-road driving task for older and younger drivers.Methods: Five older drivers (Mean age = 74.60 years [2.97]) and five younger drivers (Mean age = 30.00 years [3.08]) completed a series of cognitive assessments (Montreal Cognitive Assessment [MoCA], Mini Mental Status Examination [MMSE]; Trail Making Test [Trails A and Trails B]) and an on-road driving task along a pre-determined, standardized urban route in their own vehicle. Driving performance was observed and scored by a single trained observer using a standardized procedure, where driving behaviors (appropriate and inappropriate) were scored for intersection negotiation, lane changing and merging. During the on-road driving task, participants’ HR was monitored with an unobtrusive physiological monitor.Results: Younger drivers performed significantly better on all cognitive assessments compared to older drivers (MoCA: t(8) = 3.882, p < 0.01; MMSE: t(8) = 2.954, p < 0.05; Trails A: t(8) = -2.499, p < 0.05; Trails B: t(8) = - 3.262, p < 0.05). Analyses of participants’ performance during the on-road driving task revealed a high level of appropriate overall driving behavior (M = 87%, SD = 7.62, Range = 73-95%), including intersection negotiation (M = 89%, SD = 8.37%), lane changing (M = 100%), and merging (M = 53%, SD = 28.28%). The overall proportion of appropriate driving behavior did not significantly differ across age groups (Younger drivers: M = 87.6%, SD = 9.04; Older drivers: M = 87.0%, SD = 6.96; t(8) = .118, p = 0.91).Conclusions: Although older drivers scored lower than younger drivers on the cognitive assessments, there was no indication of ‘cognitive overload’ among older drivers based on HR response to the on-road driving task. The results provide preliminary evidence that mild age-related cognitive impairment may not pose a motor vehicle crash hazard for the wider older driver population. To maintain safe mobility of the aging population, further research into the specific crash risk factors in the older driver population is warranted.

description: The objective of this study is to investigate the nature of non-partisan identities and their impact on policy positions. In particular, the impact of identities around the support and opposition to secession in Catalonia and their impact on taxation preferences. I use two survey questions to measure secession identities and a survey experiment to analyse the impact of these identities on taxation. The experiment’s treatment links those who support secession with agreeing with higher taxation before asking members of the treatment group about their opinion on taxation. The answers are contrasted with a control group whose members are only asked about their taxation preferences. My interest is examining how the treatment changes the position on taxation preferences depending on the respondent’s identity regarding the groups who support and oppose the independence of Catalonia.

description: ABSTRACTObjectivesOne of the main requirements of a protective bicycle helmet is to provide and maintain adequate coverage to the head. A poorly fitting or fastened helmet may be displaced during normal use or even ejected during a crash. The aims of the current study were to identify factors that influence the size of helmet worn, identify factors that influence in use helmet position and adjustment, and examine the effects of helmet size worn and adjustment on helmet stability.MethodsRecreational and commuter cyclists in Sydney were surveyed to determine how helmet size and/or adjustment affected helmet stability in the real world. Anthropometric characteristics of the head were measured and, to assess helmet stability, a test analogous to the requirements of the Australian bicycle helmet standard was undertaken.Results267 cyclists were recruited across all age groups and 91% wore an AS/NZS 2063 compliant helmet. The main ethnic group was Europeans (71%) followed by Asian (18%). The circumferences of the cyclists’ heads matched well the circumference of the relevant ISO headform for the chosen helmet size, but the head shapes differed with respect to ISO headforms. Age and gender were associated with wearing an incorrect sized helmet and helmet adjustment. Older males (<55 years) were most likely to wear an incorrectly sized helmet. Adult males in the 35-54 year age group were most likely to wear a correctly adjusted helmet. Using quasi-static helmet stability tests, it was found that the correctness of adjustment, rather than size, head dimensions or shape significantly affected helmet stability in all test directions.ConclusionsBicycle helmets worn by recreational and commuter cyclists are often the wrong size and are often worn and adjusted incorrectly, especially in children and young people. Cyclists need to be encouraged to adjust their helmets correctly. Current headforms used in standards testing may not be representative of cyclists’ head shapes. This may create challenges to helmet suppliers if on one hand they optimise the helmet for meeting tests on ISO related headforms, while on the other seek to offer greater range of sizes.

description: F1 hybrid populations from crosses of 2 selections of V. berlandieri and 4 cultivars of V. vinifera showed generally low chloride accumulation, as in V. berlandieri, with some small variations related to particular parents. Backcross populations from crosses of 2 F1 hybrid selections and 2 of the cultivars of V. vinifera showed a discontinuous distribution with about half of each population showing low chloride accumulation as in V. berlandieri, and the rest higher chloride, although not as high as in the V. vinifera cultivars. Neither yield nor berry weight in the backcross populations was linked with chloride accumulation. Wines made from a few of the higher yielding backcross seedlings were comparable with wines from selections of V. vinifera. Chloridanreicherung bei F1-Hybriden und Rückkreuzungen von Vitis berlandieri und Vitis vinifera Die F1-Populationen aus der Kreuzung von 2 Vitis-berlandieri-Klonen und 4 V.-vinifera-Sorten zeigten im allgemeinen, ähnlich wie V. berlandieri, nur eine schwache Chloridanreicherung; geringfügige Abweichungen traten in Verbindung mit bestimmten Kreuzungseltern auf. Bei den Rückkreuzungspopulationen aus 2 F1-Klonen und 2 V.-vinifera-Sorten wurde eine diskontinuierliche Verteilung der Chloridanreicherung beobachtet; die einzelnen Populationen setzten sich jeweils etwa zur Hälfte aus Sämlingen mit schwacher und mit stärkerer Chloridanreicherung zusammen, die allerdings nicht so hoch wie bei den V.-vinifera-Sorten war. In den Rückkreuzungspopulationen waren weder Traubenertrag noch Beerengewicht mit der Chloridanreicherung verknüpft. Die Weine, die von etlichen der stärker tragenden Rückkreuzungssämlinge gewonnen wurden, waren den Weinen von V.-vinifera-Klonen vergleichbar.

Juist bij hetgaan ontbreken van deze programma’s groeit wel de be-hoefte om de rol van ouders bij de ontwikkeling vanjonge kinderen (0-6 jaar) na-drukkelijker in beeld te brengen.Er is op dit gebied veel onderzoek, met name uit de Verenigde Staten, dat laat zien dat ouderbetrokkenheid incombinatie met centrumgerichte voorzieningen goed kan worden ingericht, maar het ontbreekt aan een analysevan de cruciale factoren en omzetting daarvan in werkmodellen voor de Nederlandse situatie.Op verzoek van het ministerie van OCW heeft het ITS - Expertisecentrum Ouders, Radboud UniversiteitNijmegen, een analyse gemaakt van de cruciale factoren van VVE-programma’s in binnen- en buitenland en deomzetting in werkmodellen voor de Nederlandse situatie.Het onderzoek startte begin 2007 en is medio 2008 afgerond.

description: Grapes were crushed in the presence of high levels of the anti-oxidants SO2 and ascorbic acid, in an atmosphere deprived of oxygen. Hydroxycinnamic derivatives, particularly caftaric acid in the grape juice were found in much higher amounts than when the usual processing methods were employed. Partial oxidation of caftaric acid is not only very rapid and extensive during unprotected grflpe crushing and juice separation but gives a major reaction product that behaves as a single entity and survives through vinification. It gives a sharp HPLC peak and behaves reciprocally with caftaric, i.e., when caftaric acid in must remains high relative to the berry content the reaction product is low and vice versa. The product appeared identical in all grape varieties tested. The reaction product is about one-sixth as extractable by immiscible solvents as is the parent caftaric acid. It can constitute a large part of the 320 nm absorbance of a wine and explains the variable results and poor yields in attempts to isolate caftaric acid from ordinary wine or juice. L'acide caftarique des raisins et sa conversion en produit de réaction au cours de la vinification A l'aide de HPLC il a été mis en évidence que l'acide caftarique (caffeoyl tartrique) subit des pertes rapides lors du foulage des raisins dans le cas où ceux-ci ne sont pas complètement protégés contre l'oxidation, comme par ex. foulage en atmosphère inerte en présence d'un niveau élevé de métabisulfite de potassium et d'acide ascorbique. En l'absence de telles précautions les valeurs de la teneur originelle en acide caftarique, considérées comme étant caractéristiques des variétés de vigne, sont douteuses. Des échantillons totalement protégés de 5 variétés blanches et 3 variétés rouges de Vitis vinifera, mûres, se rangent entre 200 mg/l de jus pour Grenache et 50 mg/l pour Carignane. Dans la mesure que l'exposition à l'oxygène et l'activité de phénolase sont évaluables la perte peut être importante. Une majeure partie de cette perte consiste dans un produit de réaction de l'acide caftarique ici pour la première fois décelé (CRP). Ce CRP peut pénétrer dans le vin et sa détermination par HPLC ainsi que celle de l'acide caftarique non transformé montrent, en fonction de la variété de vigne, une grande conversion au cours de la préparation normale du moût. De telles analyses de vins peuvent servir d'indicateurs de l'exposition à l'oxygène au cours de la préparation du moût. La nature du CRP est actuellement étudiée et sa présence peut contribuer à expliquer la faible récupération de l'acide caftarique du moût ou du vin.

description: Nearly 1800 seedlings of 27 hybrid families were screened for resistance to A. tumefaciens strain AT-1 belonging to biotype 3. The tested families included 12 crosses of sensitive and of resistant phenotypes, and 15 self-pollinated families both of sensitive and of resistant parents. Resistance originated from V. amurensis. The segregation ratio corresponded to 1 : 1 among the crosses and was 3 : 1 (resistant to sensitive) among the selfings of resistant parents. All seedlings from selved susceptible parents formed tumors. According to our results, a Mendelian dominant inheritance can be proposed for resistance to A. tumefaciens strain AT-1. Untersuchungen zur Vererbung der Mauke-Resistenz bei der Rebe Annähernd 1800 Genotypen aus 27 Kreuzungsfamilien wurden auf ihre Anfälligkeit gegen den Stamm AT-1 des Biotyps 3 von Agrobacterium tumefaciens geprüft. Die untersuchten Kreuzungsfamilien umfaßten 12 Kreuzungskombinationen resistenter und anfälliger Phänotypen und 15 Selbstungen resistenter und anfälliger Eltern. Die Quelle der Mauke-Resistenz ist Vitis amurensis. Das Aufspaltungsverhältnis zwischen resistenten und anfälligen Sämlingen beträgt bei Fremdbefruchtung 1 : 1 und bei Selbstung der resistenten Eltern 3 : 1; bei Selbstung der anfälligen Eltern bildete jeder Sämling Tumoren aus. Aufgrund der Ergebnisse kann eine dominante Vererbung der Resistenz gegen A. tumefaciens AT-1 angenommen werden.

description: Differences in yield between Sultana clones were found to be partly transmissible by grafting and partly not. The most important graft transmissible factor was leafroll, mild symptoms being associat.ed with yield reduction in 3 out of 6 seasons with a mean overall of 14 %, and severe symptoms in all 6 seasons with a mean of 35 %. The lower yields were related to fewer bunches per vine and in some seasons for severe leafroll with fewer berries per bunch. Shoot growth was delayed in spring with severe leafroll and less total annual growth was produced. There was a smaller reduction in total annual growth with mild leafrqll. Severe leafroll did not alter the colour of the fruit, either fresh, or dried with or without dipping. Sugar concentration was only slightly reduced when either mild or severe leafroll was present. Fanleaf virus in addition to severe leafroll was associated with a further reduction in yield and growth in some seasons. Yield differences not transmissible by grafting ranged up to about 50 %. The lowest yielding source vine which did not transmit reduced yield by grafting also showed puckered leaf and more oblate berry characters which were not transmitted by grafting. This was the only source vine showing any obvious morphological differences. Ertragsdifferenzen zwischen Sultana-Klonen in Beziehung zum Grad der Viruserkrankung und zu genetischen Faktoren Ertragsdifferenzen zwischen Sultana-Klonen konnten teilweise durch Pfropfung übertragen werden, teilweise nicht. Der wichtigste pfropfübertragbare Faktor war die Rollkrankheit. Beim Vorliegen leichter Krankheitssymptome war der Traubenertrag in 3 von 6 Jahren um durchschnittlich 14 % verringert; bei stark rollkranken Reben war in allen 6 Jahren ein mittlerer Ertragsrückgang von 35 % zu verzeichnen. Die niedrigeren Erträge waren durch weniger Trauben je Rebe, in einigen Jahren bei starker Erkrankung auch durch weniger Beeren je Traube bedingt. Das Triebwachstum war bei schwerer Rollkrankheit im Frühjahr verzögert, und es wurde weniger Holz erzeugt; bei leichter Erkrankung war die Holzproduktion weniger rückläufig. Starke Erkrankung veränderte die Beerenfärbung nicht, weder bei frischen noch bei getauchten oder nichtgetauchten getrockneten Beeren. Die Zuckerkonzentration war sowohl bei milder wie bei starker Rollkrankheit nur geringfügig vermindert. Schwere Rollkrankheit mit zusätzlichem Fanleafvirus war in einigen Jahren mit einer weiteren Verringerung von Traubenertrag und Holzproduktion verbunden. Die durch Pfropfung nicht übertragbaren Ertragsunterschiede erreichten annähernd 50 %. Die am schwächsten tragende Ausgangsrebe dieser Kategorie zeigte runzliges Laub und stärker abgeplattete Beeren; diese Merkmale waren nicht pfropfübertragbar. Nur diese eine Ausgangsrebe wies überhaupt deutliche morphologische Abweichungen auf.

description: Streszczenie W artykule zaprezentowane są podstawowe metody wspierania sportu przez instytucje samorządowe i rządowe, ze szczególnym uwzględnieniem finansowania klubów sportowych oraz stypendiów, nagród i wyróżnień dla sportowców. Autorzy omawiają zadania i kompetencje jednostek samorządu terytorialnego, Rad Sportu oraz Ministra Sportu. Celem pracy jest przedstawienie podstawowych regulacji prawnych dotyczących wpływu państwa na promocję kultury fizycznej. Podsumowując należy stwierdzić, że wspieranie sportu należy do zadań zarówno jednostek samorządu terytorialnego, jak i organów centralnych. Zauważyć należy również, że wspieranie owo ma charakter głównie finansowy, ale także organizacyjny. Organ centralny jakim jest minister do spraw kultury fizycznej zajmuje się wspieraniem sportowców na najwyższym poziomie. Wsparcie dla reprezentantów Polski, po spełnieniu szeregu dodatkowych warunków dotyczy także sportowców tzw. emerytowanych, co świadczy o estymie jaką cieszą się u ustawodawcy sportowcy, którzy uzyskali niegdyś wybitne osiągnięcia sportowe na światowym poziomie. Świadczenia dla zakwalifikowanych sportowców, którzy z przyczyn systemowych nie wzięli udziału w najważniejszych międzynarodowych imprezach sportowych świadczą o chęci naprawienia ,,dawnych błędów” przez organy państwowe. Abstract Article is presented basic methods of promotion of the sport by the local government and Government, with particular regard to the financing of sports clubs and scholarships, awards and honors for athletes. The authors discuss the tasks and competencies of local government units, the councils and the Minister of sport. The aim of the work is to provide the basic legal framework for the impact of Member States for the promotion of physical culture. In conclusion, it should be noted that the promotion of the sport belongs to the tasks of both units of local government and the central authorities. It should also be noted that the promotion of a Word is mostly financial, but also the chart. The central authority of a minister for physical culture takes care of supporting athletes at the highest level. Support for the Polish House of representatives, after dealing with a number of additional conditions also applies to athletes. retired, suggesting that esteem are on lawmakers who have athletes once the outstanding sports at world level. Benefits for qualified athletes, who for reasons of system participated in the most important international sports events are evidence of a desire to make good, “old mistakes” by public authorities.

description: Mit Hilfe gaschromatographisch-massenspektrometrischer Untersuchungen konnten wir 4 weitere Monoterpendiole erstmals im Traubenmost und Wein (Rebsorte Morio-Muskat) nachweisen: • 3, 7-Dimethyl-7-octen-1,6-diol • (Z)-3,7-Dimethyl-2,7-octadien-1,6-diol - • (E)-3,7-Dimethyl-2, 7-octadien-1,6-diol • (E,E)-3, 7-Dimethyl-2,5-octadien-1, 7-diol Die Bedeutung dieser Diole im Hinblick auf die Entstehung einiger Monoterpenäther des Trauben- und Weinaromas wird diskutiert. Die identifizierten Verbindungen fügen sich in den von ÜHLOFF und Mitarbeitern vorgeschlagenen Bildungsweg einiger Monoterpenäther durch Photooxidation von Monoterpenalkoholen ein. Über das Vorkommen dieser Monoterpendiole in biologischem Material wurde bisher nicht berichtet. New monoterpenoic alcohols in grape must and wine and their significance for the biogenesis of some cyclic monoterpene ethers With the aid of GC-MS analyses it was possible to identify the following additional monoterpene diols in Morio-Muskat grape must and wine: • 3, 7-Dimethyl-7-octene-1,6-diol • (Z)-3, 7-Dimethyl-2, 7-octadiene-1,6-diol • (E)-3, 7-Dimethyl-2,7-octadiene-l,6-diol • (E,E)-3,7-Dimethyl-2,5-octadiene-1,7-diol The significance of these diols with respect to the formation of some monoterpene ethers in grape and wine aroma is discussed. The presence of the identified diols can be accounted for in terms of the pathway for some monoterpene ethers by photooxidation of monoterpene alcohols as proposed by ÜHWFF and collaborators. The occurrence of these monoterpene diols in biological material has not been reported before.

description: Die komparatistisch angelegte Arbeit untersucht auf Basis der zum Teil ökokritisch nuancierten 'Human-Animal Studies' unterschiedliche Tier-Mensch-Relationen und -Interaktionen in ausgewählten Werken von Thomas Mann, Juan Ramón Jiménez, Theodor Fontane und Miguel de Unamuno. Hierbei liegt der Fokus insbesondere auf möglichen graduellen Unterschieden und Gemeinsamkeiten nichtmenschlicher Tiere und Menschen innerhalb einer Tier-Mensch-Relation und -Interaktion sowie auf der Hinterfragung und Analyse der damit verbundenen 'Agency' – d.h. der Handlungsfähigkeit sowie -unfähigkeit beider Subjekte im Kontext ihres Aufeinandertreffens. So wird u.a. eruiert, inwieweit den werkimmanenten nichtmenschlichen Tieren eine gewisse kommunikative, agierende Subjektivität literarisch zu- oder abgesprochen wird – auch im Hinblick auf ihre möglichen mentalen Leistungen, Empfindungen oder Bedürfnisse. Des Weiteren schließt die Arbeit neben der individuellen Beleuchtung der interagierenden Protagonisten und einer humanimalischen, ökokritischen Analyse der dort literarisch dargebotenen Umwelt bzw. Natur zudem Untersuchungen und Reflexionen über den im jeweiligen Werk inhärenten Sprachduktus mit ein. Die Aufnahme vielschichtiger Analyseaspekte ermöglicht so eine detaillierte Visualisierung von Tier-Mensch-Tableaus, durch die neue, alternative Perspektiven entstehen sowie Schlussfolgerungen und Resultate angesichts des im Werk jeweilig (re)präsentierten Tier-Mensch-Verhältnisses exemplifiziert werden können.
