Abstract (German): Bei zunehmender Schiffsgeschwindigkeit und -gröβe müssen viele Fahrtgebiete, wie z.B. die Ostsee, als Flachwasserregionen betrachtet werden. Um ein optimales Schiff für den Durchgangsverkehr im Tief- und Flachwasser entwickeln zu können, ist eine genaue Prognose der wassertiefenbedingten Änderung der Geschwindigkeit sowie des Widerstands und des Leistungsbedarfs erforderlich. Durch eine systematische Analyse der Messungen für Schiffe bei verschiedenen Wassertiefen entsteht ein neues Verfahren zur Umrechnung des Widerstands und der Propulsionseigenschaften. Das Verfahren basiert auf einer sogenannten Effektivgeschwindigkeit, die durch die dynamische mittlere Absenkung und den geometrischen Versperrungseffekt definiert ist. Da einerseits diese Effektivgeschwindigkeit die Zusammenwirkung von Schiffsgeometrie, Bodentopographie und Fahrdynamik repräsentiert und andererseits mit Hilfe von Potentialmethoden ausreichend genau berechnet werden kann, bietet das neue Verfahren gegenüber bisherigen empirischen Abschätzungen vor allem auch die Möglichkeit der Umrechnung der Propulsionseigenschaften zwischen verschiedenen Wassertiefen.

مستخلص: Traditional Chinese medicine (TCM) has more than 2,000 years of history and has gained widespread clinical applications. However, the explicit role of TCM in preventing and treating cardiovascular disease remains unclear due to a lack of sound scientific evidence. Currently available randomized controlled trials on TCM are flawed, with small sample sizes and diverse outcomes, making it difficult to draw definite conclusions about the actual benefits and harms of TCM. Here, we systematically assessed the efficacy and safety of TCM for cardiovascular disease, as well as the pharmacological effects of active TCM ingredients on the cardiovascular system and potential mechanisms. Results indicate that TCM might be used as a complementary and alternative approach to the primary and secondary prevention of cardiovascular disease. However, further rigorously designed randomized controlled trials are warranted to assess the effect of TCM on long-term hard endpoints in patients with cardiovascular disease.

المؤلفون: Tao Jiang

المصدر: Information -- Wissenschaft und Praxis; jan/feb2008, Vol. 59 Issue 1, p32-36, 5p

الملخص (بالإنجليزية): The K3 technical architecture is described with its three main components: K3Forum (discourse), K3Vis (visualization), and K3Wiki (collaborative text production such as summaries). K3 uses free and open software under a LGPL license. This allows free software usage, low development/modification costs and independence from commercial software provider. Due to the component-based development concept, K3 allows to add new features and functions without weakening the stability of the existing system. By documenting the main K3 components and functions and by describing the system requirements needed to transfer K3 in a new environment K3 encourages future developers to build on K3 and keep it alive. [ABSTRACT FROM AUTHOR]

Abstract (German): Die K3-Architektur zur technischen Entwicklung und Realisierung des netzbasierten Wissensmanagement in der Lehre wird dargestellt. Das aktuelle K3-System besteht aus drei zentralen Komponenten; K3Forum (Diskurs), K3Vis (Visualisierung) und K3Wiki (kollaborative Textproduktion, z. B. für Zusammenfassungen). K3 verwendet Open-Source-Software unter der LGPL Lizenz.. Dadurch können freie Verwendung, überschaubare Entwicklungskosten und Nachhaltigkeit garantiert und die Unabhängigkeit von kommerziellen Software-Anbietern gesichert werden. Dank des komponentenbasierten Entwicklungskonzepts kann K3 ñexibel und robust laufend weiterentwickelt werden, ohne die Stabilität der bestehenden Funktionalitäten zu beeinträchtigen. Der Artikel dokumentiert exemplarisch die Hauptkomponenten und Funktionen von K3, so dass nachfolgende Entwickler leicht eine Übersicht über das K3-System gewinnen können. Die Anforderungen an den Transfer des Systems in Umgebungen außerhalb von Konstanz werden beschrieben. [ABSTRACT FROM AUTHOR]

الملخص (بالإنجليزية): The main objective of the K3 research project is to transfer the value-added potentials of asynchronous media (with respect to communication and the production of knowledge) to academic training. Using the paradigm of net-based knowledge management as suggested by Kuhlen, new didactic approaches and a complex collaborative knowledge management software system were developed and continuously improved in real life application, mainly but not only in information science courses at the university of Konstanz. The article outlines the general approach and the main features of the system for a) building knowledge collaboratively in an electronic asynchronous forum environment, b) navigating in existing knowledge structures and visualizing them and c) providing powerful tools for evaluation individual and group performance. Some research results from different evaluation studies are presented. The article is completed by an overview about other possible applications of net-based knowledge management. [ABSTRACT FROM AUTHOR]

الوصف: Im Jahr 2017/18 wurde an der Universität Bremen ein Aufgabenkonzept für Biologielehramtsstudierende entwickelt und evaluiert, das gezielt die fachspezifische Reflexionsfähigkeit in Schulpraxisphasen fördern soll. Die Ergebnisse dieser Studie zeigten, dass die Studierenden die Reflexionsdimensionen Theoriebezug, Perspektivübernahme, Handlungsalternativen und Professionalisierung berücksichtigten, jedoch innerhalb dieser Reflexionsdimensionen nur durchschnittliche Ergebnisse in die Tiefe erreicht wurden. Basierend auf diesen Studienergebnissen wird in einem Folgeprojekt nach dem Design-Based Research (DBR)-Ansatz eine Intervention gestaltet, die über das bisher entwickelte Aufgabenkonzept hinaus durch den Einsatz von authentischen, fremden Unterrichtsvideos die fachspezifische Reflexionsfähigkeit insbesondere in die Tiefe fördern soll. Im Folgenden wird eine Projektskizze vorgestellt.

الوصف: With literature and empirical evidence, this article argues against the existing claim that what if-questions are idioms and proposes that they are the result of the syntactic and semantic combination of what and if-conditionals. With further evidence, it is argued that what can be a propositional anaphor which occurs in different contexts, rather than being restricted to what if-questions. A formal characterization of the syntactic and semantic properties of the propositional what is formulated in the framework of Dynamic Syntax, demonstrating how this word makes semantic and syntactic contributions to the interpretation of utterances in English as a mechanism of interaction between interlocutors.

الوصف: Abstract Background Modern breeding strategies have resulted in significant differences in muscle mass between indigenous chicken and specialized broiler. However, the molecular regulatory mechanisms that underlie these differences remain elusive. The aim of this study was to identify key genes and regulatory mechanisms underlying differences in breast muscle development between indigenous chicken and specialized broiler. Results Two time-series RNA-sequencing profiles of breast muscles were generated from commercial Arbor Acres (AA) broiler (fast-growing) and Chinese indigenous Lushi blue-shelled-egg (LS) chicken (slow-growing) at embryonic days 10, 14, and 18, and post-hatching day 1 and weeks 1, 3, and 5. Principal component analysis of the transcriptome profiles showed that the top four principal components accounted for more than 80% of the total variance in each breed. The developmental axes between the AA and LS chicken overlapped at the embryonic stages but gradually separated at the adult stages. Integrative investigation of differentially-expressed transcripts contained in the top four principal components identified 44 genes that formed a molecular network associated with differences in breast muscle mass between the two breeds. In addition, alternative splicing analysis revealed that genes with multiple isoforms always had one dominant transcript that exhibited a significantly higher expression level than the others. Among the 44 genes, the TNFRSF6B gene, a mediator of signal transduction pathways and cell proliferation, harbored two alternative splicing isoforms, TNFRSF6B-X1 and TNFRSF6B-X2. TNFRSF6B-X1 was the dominant isoform in both breeds before the age of one week. A switching event of the dominant isoform occurred at one week of age, resulting in TNFRSF6B-X2 being the dominant isoform in AA broiler, whereas TNFRSF6B-X1 remained the dominant isoform in LS chicken. Gain-of-function assays demonstrated that both isoforms promoted the proliferation of chicken primary myoblasts, but only TNFRSF6B-X2 augmented the differentiation and intracellular protein content of chicken primary myoblasts. Conclusions For the first time, we identified several key genes and dominant isoforms that may be responsible for differences in muscle mass between slow-growing indigenous chicken and fast-growing commercial broiler. These findings provide new insights into the regulatory mechanisms underlying breast muscle development in chicken.

مستخلص: Ethnopharmacological relevance: Fufangkushen colon-coated capsule (FCC) was a newly developed herbal drug for treating ulcerative colitis (UC) patients with traditional Chinese medicine (TCM) pattern of damp-heat accumulating in the interior. Objective: To explore the efficacy and safety of FCC in the treatment of active UC compared with Huidi (HD, mesalazine enteric-coated tablets) were evaluated in a double-blinded and randomized clinical trial. Materials and Methods: In the double-blind, double-dummy, multicenter, randomized and controlled study, 320 active UC patients with TCM pattern of damp-heat accumulating in the interior were assigned to two groups: 240 treated with FCC plus HD placebo treatment, 80 with HD plus FCC placebo. The drugs and their corresponding placebos were administrated at advised dosage for 8 weeks. The primary endpoint was a positive clinical response at week 8, and Mayo scoring system was employed for assessment of UC activity. Results: At the 8th week, 72.50 % of patients in FCC group (170 of 234) and 65.00 % of patients in HD group (52 of 80) had achieved a clinical response. There was no statistically significance between the 2 groups (P > 0.05). The proportions of patients who had a clinical remission was similar in 2 groups (41.50 % in FCC group, 41.25 % in HD group, P > 0.05), mucosal healing rate at week 8 in the two groups were also without significant difference (55.13 % in FCC group, 55.00 % in HD group, P > 0.05). Mayo scores at week 8 showed no statistically difference in the two groups. No significant differences were observed between the safety profiles of the 2 groups (P > 0.05). No severe AEs were reported in either group. The latent class analysis indicated that FCC was superior applicable for the left hemicolon involved patients than HD. Conclusions: Compared with HD, a mesalamine enteric-coated tablet, FCC is similarly effective and safe in the treatment of active UC with TCM pattern of damp-heat accumulation interior pattern. In addition, FCC indicates superior effect in the treatment of UC with inflamed area of the left hemicolon than HD. [Copyright &y& Elsevier]

الوصف: Smoke taint in grapes and wine is complicated. If a vineyard is exposed to smoke, there are a whole range of factors that determine whether or not the wine eventually made from those grapes will be smoke-affected and to what degree. While many of those factors are now quite well understood (Coulter, 2022; Parker et al., 2023), questions still remain about what consumers think. Do they notice smoke characters in wine? Do they like or dislike them? How strong do smoke characters need to be to cause a reaction in consumers? And are all consumers the same when it comes to smoky wines? Three recent consumer sensory studies at the AWRI aimed to learn more about the answers to these questions. This article presents a summary of the results and conclusions of this work. Full details were recently published by Bilogrevic et al. (2023) as an open access article in the peer-reviewed journal, OENO One (https://doi.org/10.20870/oeno-one.2023.57.2.7261Test).
