description: Decline and death of young grapevines (Vitis vinifera L.) cultivar Italia, grafted on the rootstock V. berlandieri PLANCHON x V. rupestris SCHEELE 140 Ru., have been detected in a grape area of Sicily. The phenomena were initially characterized by necrotic areas on the rootstock and consequent scarce growth and progressive chlorosis of the leaves. From the affected plants a fungus, identified as Phoma glomerata (CORDA) WOLLENW. et HOCHAPF. (= Peyronellaea glomerata (CORDA) GOIDANICH), has been consistently isolated. Such an isolate has reproduced the syndrome when inoculated on rooted cuttings of the rootstocks V. berlandieri x V. rupestris 140 Ru. and 1103 P., V. riparia MICHAuX x V. berlandieri KOBER 5BB and V. rupestris DU LOT. From the plants with artificial inoculations it was possible to reisolate the same fungus. On such a basis, P. glomerata has to be considered the causal agent of the disease. Infections take place through the wounds made on the young trunks by removing the rootstock spurs from the field-grafted plants. In vitro assays have proved that the isolate of P. glomerata is quite sensitive to the fungicides Captafol, Ziram and Carbendazim. Deperimenti di giovani piante di vite indotti da infezioni di Phoma glomerata sul portinnesto Su giovani piante di vite (Vitis vinifera L.) cv. Italia, innestate in campo sui portinnesti V. berlandieri PLANCHON X V. rupestris SCHEELE 140 Ru., sono stati notati - in un'area viticola della Sicilia - gravi fenomeni di deperimento. Le viti presentavano aree necrotiche sul portinnesto, con conseguente scarsa vegetazione e clorosi progressive delle foglie, a cui seguiva spesso la morte dell'intera pianta. Dalle piante ammalate i;' stato costantemente isolato il fungo Phoma glomerata (CORDA) WOLLENW. et HOCHAPF. (= Peyronellaea glomerata (CORDA) GOIDANICH). L'isolato ha riprodotto la sindrome in seguito ad inoculazione artificiale, su barbatelle dei portinnesti V. berlandieri x V. rupestris 140 Ru. e 1103 P.; V. rupestris DU LOT e V. riparia MICHAUX x V. berlandieri KOBER 5BB. A distanza di tempo è stato possibile reisolare dalle piante con infezione artificiale lo stesso agente patogeno; P. glomerata è pertanto da considerare l'agente del deperimento delle giovani piante di vite. Si è potuto appurrare che l'infezione avviene attraverso la ferita praticata sul tronco per asportare lo sperone del portinnesto. In prove in vitro, P. glomerata è risultato molto sensibile ai fungicidi Captafol, Ziram e Carbendazim.

description: Vertical farming is considered to play a crucial role in future food supply. Until today, the high amount of electrical energy required for artificial lighting has been problematic in this context. Various possibilities for increasing efficiency through adapted lighting conditions have been and are being investigated. However, comparably little attention is paid to increasing utilance, i.e., the amount of photons that can effectively be used by the plant. In this work, a novel targeted lighting strategy is therefore proposed that allows for a dynamic adaptation of the luminaires’ light distribution to match the effective crop size at each stage of plant growth in a fully-automated manner. It is shown that the resulting utilance can significantly be increased compared to standard full-coverage lighting. Moreover, it is found that the proposed strategy is likely to consume less than half of the electrical energy usually required for the latter. An additional increase in system efficiency can be prognosticated and the potential energy savings are estimated based on assumptions of future LED generations derived from literature.

description: Die vorliegende Arbeit verfolgt einen systematischen Ansatz zur Steigerung der Leistungsdichte von Traktionsantrieben. Ausgehend von der Definitionsgleichung der mechanischen Leistung rotierender elektrischer Maschinen bewertet sie für alle beteiligten Größen Maßnahmen, die zur Steigerung der Leistungsdichte führen. Ein Methodenteil bildet die Grundlage für die Berechnung, die Bewertung und den Vergleich unterschiedlicher Maschinen. Aus Flussverkettungen werden Kennfelder berechnet, die neben Grundwellenverlusten auch Oberwellenverluste einbeziehen. Es entsteht ein thermisches Modell, mit dem die Dauerleistung der Antriebe ermittelt wird. Zur Steigerung der Drehmomentdichte werden Kühlsysteme gegenüber-gestellt. Mit einer Methode zur Berechnung der Alterung des Isolations-systems wird Überdimensionierung vermieden und die Leistungsdichte der Maschine erhöht. Das Potenzial zur Leistungssteigerung durch den Einsatz von Kupfer als Käfigmaterial von Asynchronmaschinen und durch den Einsatz von Kobalt-Eisen für den magnetischen Kreis wird aufgezeigt. Der analytische Zusammenhang zwischen der Maximaldrehzahl elektrischer Maschinen und deren Leistungsdichte wird unter Berück-sichtigung der mechanischen Festigkeit hergeleitet. Finite Elemente Analysen bestätigen den gefundenen Zusammenhang. Die untersuchten Maßnahmen zur Leistungssteigerung werden anhand der Auslegung einer Hochdrehzahl-Asynchronmaschine für den Antrieb eines Oberklassefahrzeugs validiert. Die Wechselwirkungen mit der Leistungselektronik und dem Getriebe werden berücksichtigt. Konstruktive Maßnahmen ermöglichen die hohe Umfangsgeschwin¬digkeit von 140 m/s. In Messungen werden 3,0 kW/kg Leistungsdichte nachgewiesen. Gegenüber dem Stand der Technik wurde somit eine Steigerung der Leistungsdichte um Faktor drei erreicht.

description: Aggregated roundoff errors caused by floating-point arithmetic can make numerical code highly unreliable. Verified postconditions for floating-point functions can guarantee the accuracy of their results under specific preconditions on the function inputs, but how to systematically find an adequate precondition for a desired error bound has not been explored so far. We present two novel techniques for automatically synthesizing preconditions for floating-point functions that guarantee that user-provided accuracy requirements are satisfied. Our evaluation on a standard benchmark set shows that our approaches are complementary and able to find accurate preconditions in reasonable time.

description: C-reactive protein (CRP) is an inflammation biomarker that should be quantified accurately during infections and healing processes. Nanobodies are good candidates to replace conventional antibodies in immunodiagnostics due to their inexpensive production, simple engineering, and the possibility to obtain higher binder density on capture surfaces. Starting from the same pre-immune library, we compared the selection output resulting from two independent panning strategies, one exclusively exploiting the phage display and another in which a first round of phage display was followed by a second round of yeast display. There was a partial output convergence between the two methods, since two clones were identified using both panning protocols but the first provided several further different sequences, whereas the second favored the recovery of many copies of few clones. The isolated anti-CRP nanobodies had affinity in the low nanomolar range and were suitable for ELISA and immunoprecipitation. One of them was fused to SpyTag and exploited in combination with SpyCatcher as the immunocapture element to quantify CRP using electrochemical impedance spectroscopy. The sensitivity of the biosensor was calculated as low as 0.21 μg/mL.

description: High-flux, high-repetition-rate neutron sources are of interest in studying neutron-induced damage processes in materials relevant to fusion, ultimately guiding designs for future fusion reactors. Existing and upcoming petawatt laser systems show great potential to fulfill this need. Here, we present a platform for producing laser-driven neutron beams based on a high-repetition-rate cryogenic liquid jet target and an adaptable stacked lithium and beryllium converter. Selected ion and neutron diagnostics enable monitoring of the key parameters of both beams. A first single-shot proof-of-principle experiment successfully implemented the presented platform at the Texas Petawatt Laser facility, achieving efficient generation of a forward-directed neutron beam. This work lays the foundation for future high-repetition-rate experiments towards pulsed, high-flux, fast neutron sources for radiation-induced effect studies relevant for fusion science and applications that require neutron beams with short pulse duration.

description: Mitochondria play a critical role in providing energy, maintaining cellular metabolism, and regulating cell survival and death. To carry out these crucial functions, mitochondria employ more than 1500 proteins, distributed between two membranes and two aqueous compartments. An extensive network of dedicated proteins is engaged in importing and sorting these nuclear-encoded proteins into their designated mitochondrial compartments. Defects in this fundamental system are related to a variety of pathologies, particularly engaging the most energy-demanding tissues. In this review, we summarize the state-of-the-art knowledge about the mitochondrial protein import machinery and describe the known interrelation of its failure with age-related neurodegenerative and cardiovascular diseases.

description: The ability to form mental representations of word sounds is central to language comprehension and production, and provides the basis of grammatical development and literacy. However, this process remains poorly understood. The five empirical studies presented in this thesis address open questions related to the formation and use of word sound memories. Chapter four presents a meta-analysis of studies using the auditory lexical decision task to measure the quality of word sound representations in typically developing children and children with DLD (developmental language disorder). This chapter also provides baseline data and recommendations of use to both researchers and clinicians. The study presented in chapter five uses Bayesian multi-level regression to model large-scale parental report data from CDI’s (communicative development inventories). This study provides insight into the role that high phonological neighbourhood density plays in early word production, though not comprehension, relative to factors including word length, frequency, concreteness, and relevance to infants. The study in chapter six uses the same methodology to evaluate individual differences in the importance of neighbourhood density as a predictor of word production, and presents results with implications for the development of clinical interventions. The study in chapter seven presents a quantitative corpus analysis examining spoken word accuracy and variability rates in typically developing children recorded over a three-year period. I report the effects of age, frequency, and neighbourhood density on accuracy and variability rates, and argue against the view that such rates may provide a reliable marker of speech sound disorder. Finally, in chapter eight, I present a neural network simulation of the high neighbourhood density learning advantage reported in studies two, three, and four, and present an account of network performance that can also accommodate contradictory behavioural evidence of low-density word learning advantages. All studies are integrated within an exemplar-based framework of auditory-lexical development emphasising the mechanism of analogous generalisation. In the interests of transparency this thesis is accompanied by an online repository containing pre-registration protocols and the data and code required to reproduce each analysis: osf.io/u3qsc.

description: White Roumi grape (Vitis vinifera L.) produces low yield when planted alone. Both pollination and serological tests indicated that this problem appears to be due to the presence of partial self-incompa·tibility in its flowers. Cross-pollination is necessary in White Roumi vineyards in order to obtain abundant yields and to improve berry quality. Different degrees of cross-compatibility were found between White Roumi flowers and four grape pollina.tors. Evaluating these pollinators indicated that Red Roumi and Thompson Seedless pollen gave the highest berry set and fruiting. BezEl-N akah resulted in early ripening berries possessing the largest weight and size. Ghariby proved to be an unsuitable pollinator of White Roumi flowers. It decreased berry-set percentage and fruiting and increased percentage qf preharvest berry drop. Moreover, the berries were of poor quality. Bestäubungsversuche und serologische Untersuchungen an ägyptischen Reben Die Rebsorte White Roumi (Vitis vinifera L.) bringt allein gepflanzt nur niedrige Traubenerträge. Sowohl Bestäubungsexperimente als auch die serologische Prüfung zeigten, daß es sich hierbei um eine partielle Selbstinkompatibilität handeln dürfte. In Rebanlagen mit White Roumi ist Fremdbestäubung erforderlich, um reichliche Ernten zu erzielen und die Beerenqualität zu verbessern. Zwischen den Blüten von White Roumi und vier Pollenspendern wurden unterschiedliche Grade der Fremdverträglichkeit festgestellt. Bei Bestäubung mit Pollen von Red Roumi und Thompson Seedless waren der Beerenansatz und Fruchtertrag am höchsten. Pollen von Bez-El-Nakah hatte eine frühe Beerenreife zur Folge; die Beeren dieser Kreuzung waren am schwersten und größten. Die Sorte Ghariby erwies sich als ungeeigneter Pollenspender für die White-Roumi-Blüten; der Beerenansatz und Traubenertrag waren vermindert und der Anteil der vor der Ernte abgefallenen Beeren erhöht. Überdies waren die Beeren von geringer Qualität.

description: Methyl 2-(ureidooxy) propionate (MUP), a plant growth retardant, hastened the ripening of grape berries of Vitis vinifera L. cultivars Mataro and Sultana by about 2 weeks and 1 week, respectively. The vines were sprayed with 0.1 % solution of MUP about halfway :through the first rapid growth phase of the fruit and again 2 weeks later. Terminal and lateral shoot growth was inhibited. Ripening of berries was advanced as measured by development of colour, and changes in titratable acid and reducing sugar content. The earlier ripening of the berries may have been due to hormonal changes but the advancement was much greater than that found previously with abscisic acid or ethylene applied during the slow growth stage of berry development. Die Beschleunigung des Reifezeitpunktes von Trauben durch die Anwendung von Methyl-2-(ureidooxy)-Propionat, einen Wachstumsdämpfer Methyl-2-(ureidooxy)-Propionat (MUP), welches das Pflanzenwachstum verlangsamt, beschleunigte bei den Vitis-vinifera-Sorten Mataro und Sultana die Beerenreife um etwa 2 Wochen bzw. 1 Woche. Die Reben wurden etwa in der Mitte der ersten raschen Wachstumsphase der Beeren und ein weiteres Mal 2 Wochen später mit einer 0,1%igen MUP-Lösung besprüht. Das terminale und laterale Triebwachstum war gehemmt. Die Beerenreife war beschleunigt, wie die Entwicklung der Beerenfarbe und die Veränderungen im Gehalt an titrierbarer Säure und reduzierenden Zuckern zeigten. Die frühzeitigere Beerenreife könnte auf hormonale Veränderungen zurückgehen; allerdings war die Reife viel stärker beschleunigt als im Fall früherer Versuche, in denen während der langen Wachstumsphase der Beerenentwicklung Abscisinsäure oder Äthylen angewandt worden waren.

description: For transmission electron microscope (TEM) characterization of electro-radiation-sensitive samples, it is essential to determine the critical fluence of the sample, for it sets the limit of the fluence one can apply. Conventionally, the critical fluence is determined by monitoring the fading of the reflection spots in selected area electron diffraction (SAED) as the electron fluence accumulates. Since the critical fluence analysis involves the evaluation of numerous SAED patterns, we have applied machine learning techniques for higher efficiency, accuracy, and reliability. A U‑Net type neural network was trained to automatically identify Bragg reflections in the SAED patterns and generate integrated intensity profiles. In order to enhance the data reliability, instead of selecting single Friedel pairs, all reflection intensities inside a selected resolution range were integrated and plotted as a function of the electron fluence , offering a precise assessment of the critical fluence for desired resolution range.

Both processes were inhibited by BAP at 5 mg/l. Combined applications of ZR (even at 10 mg/l failed in cancelling this inhibition. Optimum shoot proliferation resulted with the cytokinins in combination, provided the concentration of BAP did not exceed 2 mg/l.

Bei getrennter Anwendung der Wachstumsregulatoren förderten 2 mg BAP/l oder 10 mg ZR/l das Längenwachstum und die Triebvermehrung . am meisten. Beide Vorgänge wurden durch 5 mg BAP/l unterdrückt. Diese Hemmung konnte auch nicht durch zusätzliche Anwendung von ZR, selbst nicht in der Konzentration von 10 mg/l, aufgehoben werden. Eine optimale Triebvermehrung wurde durch ZR in Verbindung mit BAP erzielt, falls die BAP-Konzentration 2 mg/l nicht überschritt.

description: In einem Hydrokulturversuch und in einem Quarzsandversuch wurde der Einfluß von HCO3- auf das Auftreten von Fe-Chlorose bei der Weinrebe untersucht. HCO3- im Nährmedium induzierte bei beiden Versuchen typische Fe-Mangelsymptome an den jüngeren Blättern, obgleich im Nährmedium Fe vorhanden war. Demgegenüber traten im Quarzsandversuch bei Abwesenheit von Fe und HCO3- im Nährmedium keine Fe-Mangelsymptome auf. Im Hydrokulturversuch waren in der Variante „ohne Fe" die Fe-Mangelsymptome wesentlich schwächer ausgeprägt als in den Varianten, die in der Nährlösung Fe + HC03 - enthielten. Ernährung mit NO3- + HCO3- wirkte stärker Chlorose auslösend als Ernährung mit NH4+ + HCO3-. In den Varianten mit Carbonat + Einleitung von C02 in die Nährlösung traten HCO3-- Konzentrationen von mehr als 10 X 10 -3M auf. Sie wirkten toxisch auf die Pflanzen. Hier wurden keine Fe-Chlorosen beobachtet. Vielmehr starben die Pflanzen dieser Variante im Verlaufe der Versuchsperiode ab. Der Gehalt der Blätter an Fe stand in keiner Beziehung zum Auftreten der Fe-Chlorose. Bicarbonate as a factor inducing iron chlorosis in grapevine (Vitis vinifera) The effect of HCO3- on the occurrence of iron chlorosis in grapevine has been studied in a solution culture experiment and in a quartz sand experiment. In both experiments, HCO3- in the nutrient medium induced typical Fe chlorotic symptoms in the younger leaves, although Fe was present in the nutrient medium. In the quartz sand experiment, absence of Fe and HCO3- in the nutrient medium did not result in Fe deficiency symptoms. In the solution culture· experiment, the Fe deficiency symptoms were less marked in the treatment "without Fe" as compared with the treatments which contained Fe + HCO3- in the nutrient solution. Iron chlorosis was more heavily induced by nutrition with NO3- + HC03 - than with NH4+ + HCO3- . In the treatments with carbonate and an additional supply of C02 to the nutrient solution, HCO3- concentrations higher than 10 X 10-3M were measured, which were toxic to the plants. In these treatments no Fe chlorosis occurred, and the plants died before the end of the experiment. The Fe content of the leaves was not related to the occurrence of Fe chlorosis.

description: The pregnane X receptor (PXR) is a nuclear receptor primarily found in the liver and intestinal tissues. It has a major role in the detoxification of xenobiotics and endobiotics via the up-regulation of genes coding for drug metabolising enzymes (DMEs). Since the discovery of the unique promiscuity of PXR due to its unusually large and flexible ligand binding domain, it has been revealed that the receptor plays a broad ‘sensing’ role in the body. Owing to the wide range of PXR agonists and the specific post-transcriptional events that occur due to its activation, it has been elucidated that adverse drug-drug interactions occur between mutual compounds sharing an affinity for the receptor. Recent in silico investigation into PXR and its interaction with the isoquinoline alkaloid, berberine chloride, has indicated that the receptor may cause changes in gene expression of not only DMEs, but also genes having vital roles in cell growth, development and apoptosis. Berberine chloride is administered as a herbal remedy in the east, with some evidence of efficacy in treating conditions such as hypertension, diabetes and cancer. Further research into the cell signalling and transcriptional modification surrounding PXR using the compound as an agonist, may elucidate novel research avenues towards better understanding a major participant in health and disease. This study aims to demonstrate the role of PXR in the expression of specific genes for detoxification and cell growth and also to lay evidence-based foundations for further research into the novel signalling activity of the receptor.

description: As part of their accreditation procedure, universities have to ensure academic feasibility of their study courses. Against that backdrop, student’s workload and study conditions are focused as indicators of quality. However, this prioritization of formal criteria is defined by the module handbooks rather than by the students themselves. Therefore, a mixed-methods-analysis at the Karlsruhe Institute of Technology (KIT) was conducted to shed light on these issues: How can individual expectations and requirements of students towards the academic learning settings be incorporated into quality assessment? Which opportunities of individual development for students exist in the academic setting and do they differ with regard to different departments at the KIT? The data of surveys completed by 324 students of the department of mechanical engineering and 242 students of the department of economics and management at the KIT are the basis of our analysis. The empirical analysis via chi-square-test and Mann-Whitney-U-Test indicates significant distinctions between students of both departments at the KIT concerning their experiences with research and inquiry and their motives for enrolling to university courses. Further analyses via interviews are planned to reveal the complex chains of reasons for this research results such as considerations of course characteristics and cultural condition.

description: Die Entwicklung der Embryosäcke wurde beschrieben. Zum Zeitpunkt des Aufblühens bestehen sie aus den Synergiden, der Eizelle und dem sekundären Embryosackkern. Bei den untersuchten Sorten Gewürztraminer, Weißer Burgunder und einem Bastard Müller-Thurgau x V. armata wurden übereinstimmende Werte für das Volumen der Kerne der Eizellen zum Zeitpunkt des Aufblühens festgestellt. Innerhalb von 24 h nach dem Aufblühen trat in den bestäubten Fruchtknoten eine Vergrößerung des Volumens der Eizellkerne auf das 1,53fache auf. Diese Vergrößerung wird mit einer Verdoppelung des DNA-Gehaltes infolge der Befruchtung erklärt. Auch bei den sekundären Embryosackkernen wurde in den bestäubten Fruchtknoten eine Zunahme des Volumens (1,76fach) beobachtet. In unbestäubten Fruchtknoten traten keine Volumenvergrößerungen der Eizellkerne und der sekundären Embryosackkerne auf. 4 d nach dem Aufblühen begannen die unbefruchteten Eizellen zu degenerieren. Unter Berücksichtigung der am Tag des Aufblühens herrschenden Temperaturen hat die Befruchtung 12-24 h nach dem Öffnen der Blüten stattgefunden. Development of the embryo sac and fertilization in grapevine The development of embryo sacs has been described. At the beginning of flowering they consist of two synergids, the egg cell and the secondary embryo sac nucleus. Investigations with the cvs. Gewürztraminer, Weisser Burgunder and a hybrid Müller-Thurgau x V. armata showed equal volumes of the nuclei of the egg cells at the beginning of flowering. 24 h thereafter, the volume of the egg cell nuclei was 1.53 times enlarged in the pollinated ovaries. This enlargement can be explained by the· duplication of the DNA content which is due to fertilization. An increase of the volume (1.76 times) was also observed in the secondary embryo sac nuclei of the pollinated ovaries. On the other hand, the ovaries which were not pollinated showed no enlargement of the volume of the egg cell nuclei and the secondary embryo sac nuclei. 4 d after the beginning of flowering, the unfertilized egg cells began to degenerate. In consideration of the temperatures during the day when flowering began, fertilizatlon occurred 12-24 h after the opening of the flowers.

description: L'étude du type sexuel dans la descendance S1 (lère génération d'autofécondation) de 6 variétés de l'espèce Vitis vinifera L. traditionellement cultivées en Alsace, nous a permis d'observer des types morphologiquement mâles, ceci chez une seule variété, le Muscat Ottonel. Ces observations ne se conforment pas aux schémas classiques d'interprétation de l'hérédité du type sexuel chez la vigne. Le rôle des cytokinines, dont le taux chez la plante peut être modifié par l'action du milieu, influençant ainsi l'expression phénotypique du type sexuel ne semble pas en cause dans notre cas. C'est plutôt dans la structure génotypique elle-même du Muscat Ottone! qu'il faut rechercher l'explication de telles observations. Observation of male sexual types in the self-fertilized progeny of the variety Muscat Ottonel (Vitis vinifera L.) Studying sexual segregation in self-fertilized lst generation progenies among 6 varieties of Vitis vinifera L. showed that one of them, Muscat Ottonel, exhibited morphologically male types. These observations do not agree with the classical genetic patterns of sexual segregation in grapevine. The observed facts do not seem to be due to cytokinins, but rather are to be attributed to the genom of the cultivar Muscat Ottonel.

description: Organogenesis was studied in cultured internodes of grapevine cultivars, hybrids and species. Adventitious root formation occurred with a wide range of media and genotypes. Adventitious buds were formed in explanrts grown in ag1tated liquid culture with NITscH medium supplemented with benzyladenine (1 μM) and 2,4-D (5 μM} or a mixture of 2,4-D and ß-naphthoxyacetic acid (5 μM). Bud formation occurred only in cultures derived from seedlings of Muscadinia rotundifolia, Gloryvine (Vitis vinifera L. x Vitis rupestris ScHEELE) and V. vinifera x Gloryvine, i.e. (Grenache x Cabernet Sauvignon) x Gloryvine and (Sumoll x Cabernet Sauvignon) x Gloryvine. Cuttings from mature vines of V. vinifera cultivars, or from clonal Gloryvine, gave explants which failed to produce buds. Results are discussed in relation to effects of composition of media, origin of explant, maturity of the mother plant and genotype. Organogenese bei Internodienexplaotaten von Reben Bei Kalluskulturen aus Internodien verschiedener Rebsorten, -kreuzungen und -arten wurde die Organogenese untersucht. Adventivwurzeln bildeten sich auf zahlreichen Nährmedien und bei vielen Genotypen. Adventivknospen entstanden an Explantaten in Schüttelkulturen auf einem flüssigen Medium nach NITSCH mit einem Zusatz von Benzyladenin (1 μM) und 2,4-D (5 μM) oder einem Gemisch von 2,4-D und ß-Naphthyloxyessigsäure (5 μM). Knospen bildeten sich nur in Kulturen aus Sämlingen von Muscadinia rotundifolia, Gloryvine (Vitis vinifera L. x Vitis rupestris SCHEELE) sowie V. vinifera x Gloryvine, nämlich (Grenache x Cabernet Sauvignon) x Gloryvine und (Sumoll x Cabernet Sauvignon) x Gloryvine. Aus ausgereiftem Holz von V. -vinifera-Sorten oder einem Gloryvine-Klon hergestellte Stecklinge ergaben Explantate, die keine Knospenbildung zeigten. Die Ergebnisse werden im Hinblick auf die Zusammensetzung der Nährmedien, den Ursprung des Explantats, den Reifezustand der Mutterpflanze und den Genotyp diskutiert.

description: A series of new imidazolium salts (1–4) as N-heterocyclic carbene (NHC) precursors have been synthesized by successive N-alkylation method. Reactions of these salts with Ag2O by varying the metal to salt ratio forms a series of new Ag(I)–NHC complexes (5–8). All compounds were characterized by physico-chemical and spectroscopic techniques. The molecular structures of 1 and 5 were characterized by single-crystal X-ray diffraction analysis. A comparative investigation of the bacterial growth inhibition potential of the salts and respective complexes indicates that 5–8 displayed good antibacterial activities on Staphylococcus aureus (ATCC 12600) and Escherichia coli (ATCC 11303) compared with the salts. Furthermore, it was observed that with increase in chain length at N-positions, the antibacterial activities also increased. Nuclease activity of the reported salts and Ag(I)–NHC complexes with nucleic acids (DNA and RNA) were also studied using agarose gel electrophoresis; the results show that the compounds do not have any apparent interaction with nucleic acids in the absence of hydrogen peroxide (H2O2). However, 5 and 8 were efficient in promoting the cleavage of nucleic acids in the presence of H2O2.

description: In order to promote pedagogically informed use of technology, educators need to develop an active, inquisitive, design-oriented mind-set. Design Patterns have been demonstrated as powerful mediators of theory-praxis conversations yet widespread adoption by the practitioner community remains a challenge (Goodyear et al., 2004). Over several years, the authors and their colleagues have facilitated many workshops in which participants shared experiences, captured these as design narratives, extracting design patterns, and applied them to novel teaching challenges represented as design scenarios. This paper analysis the value of design narratives, patterns and scenarios in scaffolding co-design processes in light of previous work in this area.

description: Background There are attempts to increase community access to misoprostol in Kenya. However, several factors may hinder such health-seeking behaviour. And to date, there is no documented evidence examining individual-level factors that may influence self-administration of the drug in Uasin Gishu County or any other part of Kenya.
 Objective This study examined the socio-demographic characteristics associated with self-induced abortion with misoprostol among women presenting themselves with abortion related complications in public health facilities in Uasin Gishu County in Kenya.
 Material and Methods From the sample, the study identified women who had induced their pregnancy with misoprostol. The association between self-induced abortion and the socio-demographic variables was then analysed using the Pearson Chi-square test. Significant variables were subjected to regression analysis after controlling for confounding. Odds Ratio (OR) with confidence interval (CI) was used where possible to ascertain the extent of the association.
 Results The prevalence of self-induced abortion with misoprostol in the County was 25.6% (137). Women who had not completed primary school were .292 times more likely to self-induce their pregnancy with misoprostol, (OR, .292; 95% CI = .10, .83; p = 0.021).
 Conclusion The prevalence of self-induced abortion with misoprostol was relatively low. The study also observed that women who had not completed primary school were more likely to self-induce their pregnancy with misoprostol.
Madanidinium loirii gen. et sp. nov. (Dinophyceae), a new marine benthic dinoflagellate from Martinique Island, Eastern Caribbean

description: A new benthic phototrophic dinoflagellate is described from sediments of a tropical marine cove at Martinique Island and its micromorphology is studied by means of light and electron microscopy. The cell contains small golden-brown chloroplasts and the oval nucleus is posterior. It is laterally compressed, almost circular in shape when viewed laterally. It consists of a small epitheca tilted toward the right lateral side and a larger hypotheca. In the left view, the cingulum is more anterior and the epitheca is reduced. The cingulum is displaced and left-handed. This organism is peculiar in having no apical pore and its thecal plate arrangement is 2′ 1a 7′′ 5c 3s 5′′′ 1′′′′. The plates are smooth with small groups of pores scattered on their surface. An area with 60–80 densely arranged pores is found near the centre of the 2′′′ plate, on the left lateral side. Morphologically, these features are different from all other laterally compressed benthic genera. In addition, molecular genetic sequences of SSU and partial LSU form a distinct and well-supported clade among dinoflagellates and support the erection of a new genus. However, molecular phylogenies inferred from ribosomal genes failed to confirm any clear relationship with other benthic taxa and affinity with other laterally compressed dinoflagellates has not been demonstrated. Hence, the taxonomic affinity of Madanidinium loirii with a defined order and family is unclear at the moment.
