Skladateljski proces se praviloma ne konča z izdelavo avtografa. Kopije, ki so jih pripravljali profesionalni pisarji, so Beethovnu pogosto služile kot osnova za včasih tudi obsežne revizije; pogosto ...dokončni avtorjev notni zapis iz avtografa niti še ni razviden. Razveseljivo je, da imamo zdaj na voljo obsežen kopistov prepis neke celotne simfonije, ki ga je Beethoven tudi sam pregledal, in sicer kljub temu da je ohranjen tudi avtograf – tako v tiskani faksimilirani kakor v digitalizirani lahko dostopni spletni obliki – in kljub temu da prepis niti nima veliko Beethovnovih pripisov. Gre za prepis partiture Pastoralne simfonije, ki jo je kopist Joseph Klumpar izdelal kot tretjo kopijo simfonije (pred tem je prepisal že orkestrske glasove in partituro za založnika Breitkopf & Härtel) in je pri prvi javni izvedbi decembra 1808 služila kot izvajalska partitura. Danes jo hrani Narodna in univerzitetna knjižnica v Ljubljani.
Between 1929 and 1930 the
Der Kreis
journal hosted a debate among art historians and museum directors on how art copies were changing the museum landscape. The so-called
Hamburger Faksimile-Streit
...constitutes a crucial moment in the Weimarian theoretical debate on the categories of copy and original, culminating a few years later in Benjamin’s well-known essay on the work of art. After examining the theses of the main participants in the debate, this article focus on the position of curator and museum director Alexander Dorner – the only one advocating for the non-superiority of originals over copies in art museums – and on his relationship with Walter Benjamin’s later theories.
Zusammenfassung Thermopapiere werden zum schnellen Ausdruck von Belegen eingesetzt. Sie enthalten ein thermochromes Dreikomponentengemisch aus Leukofarbstoff und einem sauren phenolischen Entwickler, ...eingearbeitet in einen langkettigen Alkohol, das Solvens. Der Entwickler ist wegen der Verkapselung des Leukofarbstoffs im Solvens nicht in der Lage, diesen zu protonieren und damit in seine farbige Form überzuführen. Erst durch Einwirkung von Hitze schmilzt das Solvens, wodurch die Farbreaktion des Entwicklers mit dem Leukofarbstoff ermöglicht wird. In diesem Beitrag werden thermochrome Dreikomponentengemische aus Kristallviolettlacton (CVL) als Leukofarbstoff, Alkylgallat als Entwickler und 1‐Tetradecanol als Solvens vorgestellt, die sich sehr gut dazu eignen, den Einfluss der Löslichkeit vom Entwickler im Solvens in Abhängigkeit der Alkylkettenlängendifferenz ihrer Moleküle auf das thermochrome Verhalten experimentell zu zeigen. Auch der Einfluss hoher bzw. geringer Solvensanteile auf den Farbkontrast wird deutlich. Wir untersuchen, weshalb heißes Wasser Thermopapier schwarz färbt, heißes Öl hingegen keine Farbreaktion auslöst, womit die Thematik um thermochrome Gemische für die Schule in einen interessanten Kontext mit starkem Alltagsbezug gesetzt wird.
Summary Facsimile paper, so‐called thermal paper, is an example for thermographic recording material which is utilised for fast printing of receipts and tickets. These papers consist of a thermochromic three‐component mixture of a colourless leuco dye and a weak acidic developer mixed with a high melting long‐chain alcohol solvent. The developer is encapsulated in the solvent and therefore not able to protonate the pH‐sensitive leuco dye molecules to build the coloured state of the mixture. A striking colour change occurs upon heating the composition and melting the solvent whereby the developer is free to react with the leuco dye. Thermochromic composites formulated from the colour former Crystal Violet lactone (CVL), an alkyl gallate as developer and 1‐tetradecanol as solvent are presented in this article. The simple contact with hot water leads to colour reaction on thermal paper, whereas no colour change occurs after contact with hot oil. Based on these phenomena on thermal paper, we have found an interesting concept to demonstrate thermochromic behaviour for science education in school.

The key roles played by phospholipids in many cellular processes, has led to the development of model systems, to explore both lipid-lipid and lipid-peptide interactions. Biomimetic giant unilamellar ...vesicles represent close facsimiles of in vivo cellular membranes, although currently their widespread use in research is hindered by difficulties involving their integration into high-throughput techniques, for exploring membrane biology intensively in situ. This paper presents an integrated microfluidic device for the production, manipulation and high-throughput analysis of giant unilamellar vesicles. Its utility is demonstrated by exploring the lipid interaction dynamics of the pore-forming antimicrobial peptide melittin, assessed through the release of fluorescent dyes from within biomimetic vesicles, with membrane compositions similar to mammalian plasma membranes.
The main objective of this paper is to reduce the timing of higher officials to sign in large number of same documents. Manual signing of documents adds time shortage in Public Work Department. ...Moreover, the manual process is time consuming and not suitable for signing a greater number of documents. The proposed model involves the arrangement of documents, positioning of facsimile, stamping the facsimile and take out the printed documents to distribute station. Thus, this model signs a greater number of documents within a short time. Pneumatic power is fruitfully utilized in this paper and the system is controlled by an Arduino controller. Positioning of facsimile is done by the lead screw arrangement with the help of sensors. The finished documents are then sucked by vacuum cup and taken out simultaneously. Our real time implementation helps them in unveiling such condition. The paper consists of two sections namely mechanical section and control section. The control section consists of Arduino controller and Relays. Arduino controller is used to control the DC motor and the relays are used to actuate the mechanical sections. The mechanical section consists of lead screw arrangement, pneumatic piston, suction cup and facsimile.

This volume offers detailed studies into the Physiologus, a Greek manuscript probably written in Egypt in the 2nd century CE. The Physiologus was the first Christian text to sum up a general ...understanding of nature using biblical and pagan sources and it has an extensive reception history throughout the medieval period. Its symbolic use of animals and plants, etc., has deeply influenced visual arts, literature, and heraldry, but this visual language often remains enigmatic. This book, going back to a project of the Swiss National Foundation ( Das ‹Evangelium der Natur›. Der griechische Physiologus und die Wurzeln der frühchristlichen Naturdeutung) offers new insights into the origins and the interpretation of this symbolic language.

Office machines (such as printers, scanners, facsimile machines, and copiers) can consume significant amounts of power. Most office machines have sleep modes to save power. Power management of these ...machines is usually timeout-based: a machine sleeps after being idle long enough. Setting the time-out duration can be difficult: if it is too long, the machine wastes power during idleness. If it is too short, the machine sleeps too soon and too often—the wake-up delay can significantly degrade productivity. Thus, power management is a tradeoff between saving energy and keeping response time short. Many power management policies have been published and one policy may outperform another in some scenarios. There is no definite conclusion regarding which policy is always better. This article describes two methods for office equipment power management. The first method adaptively reduces power based on a constraint of the wake-up delay. The second is a hybrid method with multiple candidate policies and it selects the most appropriate power management policy. Using 6 months of request traces from 18 different printers, we demonstrate that the hybrid policy outperforms individual policies. We also discover that power management based on business hours does not produce consistent energy savings.
Zusammenfassung Carlos Montúfar (1780-1816) war ab Quito das dritte ständige Mitglied der amerikanischen Humboldt-Expedition zusammen mit Aimé Bonpland. Das Tagebuch, das er vom 9. Juni bis zum 10. ...September 1802 kurz vor Cajamarca führte, ist von Interesse für Humboldt-Forscher, zumal Bonpland scheinbar keine Zeugnisse weder in Brief- noch in Tagebuchform überlieferte. Recherchen am Original des Montúfar-Tagebuchs ergaben, dass die 1888 veröffentlichte Transkription durch Marcos Jiménez de la Espada aus verschiedenen Gründen problematisch ist. Es muss deshalb ein Desiderat der Humboldt-Forschung sein, eine korrigierte und kommentierte Transkription vorzulegen. Das geschieht hier zusammen mit einer digitalisierten Kopie des Originals.

Resumen Carlos Montúfar (1780-1816) fue, junto con Aimé Bompland, el tercer miembro permanente de la expedición de Humboldt a Suramérica cuando partió de Quito. El diario de Montúfar abarca la porción del viaje entre el 9 de junio y el 10 de septiembre de 1802, hasta justo antes de llegar a Cajamarca. Es de particular interés para los estudios sobre Humboldt, ya que Bompland no parece haber dejado ningún relato sobre la dicha expedición ni en forma de cartas ni de diario. La transcripción del diario de Montúfar publicada en 1888 por Marcos Jiménez de la Espada resulta problemática por diversas razones. Este artículo contribuye a los Estudios Humboldtianos con una transcripción corregida y anotada del diario de Montúfar, junto con una copia digitalizada del original.
