Ausgabe- bzw. Serviertemperatur von Kaffeeheißgetränken - Orientierende Untersuchungen als Grundlage für eine Krebsrisikobewertung
No full textDie Internationale Agentur für Krebsforschung (IARC) bewertet „sehr heiß“ (> 65 °C) konsumierte Getränke als „wahrscheinlich krebserregend“. Daher ist es Zweck dieser Studie, einen ersten orientierenden Einblick in die Ausgabe- bzw. Serviertemperaturen von Kaffeegetränken im Haushalt und in der Gastronomie zu bekommen. Insgesamt wurde die Serviertemperatur von 356 Kaffees in der Gastronomie und die Ausgabetemperatur von 110 Kaffees in Haushalten erhoben. Die gemessenen Temperaturen lagen sowohl im Haushalt als auch in der Gastronomie im Mittel 10 °C über der Schwellentemperatur der IARC (Mittelwert aller Messungen: 75 °C, Standardabweichung: 5 °C). Weiterhin ist die Abkühldauer mit und ohne Zugabe von Milch zu berücksichtigen. In der Regel ist eine Mindestabkühlzeit von > 10 min bzw. eine Zugabe von > 20 ml kalter Milch ausreichend, um Kaffee auf Temperaturen von 65 °C) as “probably carcinogenic to humans”. Therefore, the purpose of this study is to obtain an initial insight into the dispensing and serving temperatures of coffee-based hot beverages in the home and in the food service industry. Overall, the study recorded the serving temperatures of 356 coffees in the food service industry and the dispensing temperatures of 110 coffees in private households. The measured temperatures were on average 10 °C above the IARC threshold temperature both in the household and in the food service industry (mean value of all measurements: 75 °C, standard deviation: 5 °C). Furthermore, the cooling period, both with and without the addition of milk, should be taken into account. As a rule, a minimum cooling time of > 10 min or the addition of > 20 mL of cold milk is sufficient to cool coffee to temperatures < 65 °C. Generally speaking, from this study, it can be concluded that the recommendation should be to cool hot beverages before drinking in most cases, either by observing a waiting period or by adding milk

AutomationML in a Continuous Products Life Cycle: A Technical Implementation of RAMI 4.0
No full textThe global market for manufacturing companies is highly competitive, especially the differences between lowwage and high-wage countries lead to various market strategies. The focus of companies in high-wage countries is often on the preservation of a technical advantage, or prime quality products. The technical advantage often come from the core areas of the manufacturers, such as machining technologies, but currently new technologies are increasingly emerging from the information technology sector. In Germany, this trend, which has been going on for several years now, is summarized under the keyword “Industrie 4.0”. By setting the focus on such technologies, there is a high chance of increasing key factors e.g. productivity or flexibility. To maintain an interoperability between the, by information technology enhanced, systems there are currently multiple concepts such as the Reference Architecture Model Industry 4.0 (RAMI 4.0) or the Industrial Internet Reference Architecture (IIRA). While IIRA focuses on interdisciplinary interoperability, the German RAMI 4.0 is particularly suitable for production-intensive industries. The RAMI 4.0 concept requires the introduction of an Asset Administration Shell for each material and immaterial object (asset), which provides several functionalities such as communication or identification. The Asset Administration Shell is connected with the asset throughout the whole product life cycle. Thus it needs to be able to save the heterogeneous data which is generated in each step of the product life cycle. Therefore an approach is necessary which is able to provide such a flexibility within the data structure and also provide the functionality to communicate range of RAMI 4.0. This contribution presents the approach of an AutomationML-based Asset Administration Shell, which is able to handle the heterogeneous data due to the AutomationML basis, provides an RAMI 4.0 compatible communication functionality and is extensible for further features. The implementation of the framework is platform-independent, which enables integration in classic PLC systems (e.g. Beckhoff) as well as several IOT Platforms (e.g. Raspberry PI)

No full textSichere Kommunikation für Industrie 4.0
No full textIndustrie 4.0 schafft mit innovativen Konzepten und Vorgehensweisen völlig neue Möglichkeiten in der Zusammenarbeit – insbesondere auch auf technischer Ebene. Anlagen, Maschinen und Produkte interagieren, tauschen Daten aus und korrespondieren stets. Dabei spielt es keine Rolle, ob mit einer Maschine in derselben Fabrikhalle oder mit einer Anlage in einem Betrieb auf der anderen Seite der Welt kommuniziert wird. Doch das funktioniert nur, wenn technische Kommunikationsmechanismen dafür sorgen, dass Industrie 4.0-Komponenten (Assets) sicher und interoperabel in Kontakt treten können.
Eine solche Industrie 4.0-konforme Kommunikation zu erörtern – das ist Ziel des vorliegenden Diskussionspapiers. Dabei liegt der Fokus klar auf den technischen Aspekten der sicheren Kommunikation. Anforderungen an die Organisation werden weitestgehend nicht betrachtet. Das Dokument richtet sich an Entscheider und Anwender im Industrie 4.0-Kontext. Neben Rahmenbedingungen und Leitprinzipien werden ihnen exemplarisch gewonnene Erkenntnisse zur Industrie 4.0-Kommunikation dargestellt, die die Ansprüche an eine sichere IT-Infrastruktur berücksichtigen
SBML Level 3 package: Render, Version 1, Release
Get PDFMany software tools provide facilities for depicting reaction network diagrams in a visual form. Two aspects of such a visual diagram can be distinguished: the layout (i.e.: the positioning and connections) of the elements in the diagram, and the graphical form of the elements (for example, the glyphs used for symbols, the properties of the lines connecting them, and so on). This document describes the SBML Level 3 Render package that complements the SBML Level 3 Layout package and provides a means of capturing the precise rendering of the elements in a diagram. The SBML Level 3 Render package provides a flexible approach to rendering that is independent of both the underlying SBML model and the Layout information. There can be one block of render information that applies to all layouts or an additional block for each layout. Many of the elements used in the current render specification are based on corresponding elements from the SVG specification. This allows us to easily convert a combination of layout information and render information into a SVG drawing
Effects of film constituents on packaging-relevant properties of sodium caseinate-based emulsion films
No full textThe objective of this study was to examine the effects of the plasticizer type (sorbitol or glycerol) and lipid concentration (oleic acid or oleic acid-beeswax mixtures) on sodium caseinate (NaCas)-based films and to investigate how, and to which extent, these parameters are affecting the technofunctional properties of NaCas-based films. Additionally, we intended to demonstrate the antioxidant potential of quercetin as a component of the described formulations. Films prepared from the different composed emulsions were characterized in terms of selected packaging-relevant properties. The results showed that the type of plasticizer and the lipid concentration had significant effect on the technofunctional properties of NaCas-based films. Contact angle measurement and evaluation of the SFE revealed rather hydrophilic than hydrophobic surfaces. Determination of the WVTR showed a significant influence (p ≤ 0.05) of the type of plasticizer towards WVTR. WVTR was clearly decreased for sorbitol-plasticized films. On the contrary, the influence of the lipid concentration was also significant (p ≤ 0.05), but not as clear as the plasticizer effect. However, at 10% (w/w) beeswax (BW) addition, there was a sharp drop in WVTR visible for glycerol-plasticized films. Measurement of the OP did not yield as clear results as suggested in preliminary test series. Although, we did not conduct systematic studies regarding the effect of the antioxidant towards the OP we showed the antioxidant potential of the described compositions. Results for the mechanical performance showed a significant influence (p ≤ 0.05) of the type of plasticizer and lipid concentration. YM and TS values were clearly higher for sorbitol-plasticized films whereas E% values were lower for sorbitol-plasticized films. Regarding the effect of the lipid concentration on the mechanical performance, no apparently visible trend could be identified. Light transmittance measurement revealed that in terms of UV-absorptivity at wavelengths between 300 nm and 400 nm, the incorporation of quercetin led to promising barrier properties against UV-light
