Concept papers outlining parameters for further development of Organic Food Processing - Crucial topics for the revision of the EU regulation 2092/91

Four concept papers outline parameters for the further development of organic food processing. They are based on other work already executed in the subproject 5 Processing in the QLIF-project, in particular the literature survey on “Underlying Principles in Organic and "Low-Input Food“ Processing – Literature Survey” published in 2004 by Schmid, Beck and Kretzschmar, as well as the “Approaches used in Organic/Low Input Food Processing - impact on food quality and safety” results of a Delphi survey from an expert consultation in 13 European countries.“ (Kretzschmar, Schmid, 2006). The four crucial topics highlighted in concept papers that have been chosen are summarised below: - 1rd Concept paper on the chances for a concept of “quality of origin” and on criteria and procedures for the evaluation of additives for organic food processing -2nd concept paper on environmental orientation of organic foods producing processing companies -3rd concept paper on processing methods and their labelling -4th concept paper on the improvement of separation practice by parallel processing of conventional and organic product

Zusatzsstoffe in ökologischen Lebensmitteln: Wie können die Zulassungsverfahren verbessert werden?

Derzeit existieren verschiedene Konzepte für die Zulassung von Zusatzstoffen und technischen Hilfsstoffen für ökologische Lebensmittel. Ihre Weiterentwicklung im Rahmen der EG-Öko-Verordnung ist dringend notwendig - eine aktuelle Studie zeigt, wie

The Efficiency of Adjusted Least Squares in the Linear Functional Relationship

A linear functional errors-in-variables model with unknown slope parameter and Gaussian errors is considered. The measurement error variance is supposed to be known, while the variance of errors in the equation is unknown. In this model a risk bound of asymptotic minimax type for arbitrary estimators is established. The bound lies above that one which was found previously in the case of both variances known. The bound is attained by an adjusted least square estimator

Öko-Verarbeitung: Traditionell? Schonend? Umweltgerecht?

Über die Grundprinzipien der ökologischen Landwirtschaft findet ein breiter Diskurs in der Gesellschaft statt. Bei der Öko-Verarbeitung ist jedoch noch unklar, welche Prinzipien ihr zugrunde liegen. Ein EU-Projekt soll Leitlinien für Verarbeiter formulieren

A Functional Reference Model for Manufacturing Execution Systems in the Automotive Industry

Being confronted with IT strategic questions of how to constantlyreduce IT operating costs and at the same time live up to everincreasing manufacturing demands, automobile manufacturers areencountering problems to find appropriate IT support forproduction planning and execution. Moreover, they are facing thechallenge to clearly define and demarcate Enterprise ResourcePlanning (ERP) and Manufacturing Execution Systems (MES)functionality. Despite the existence of a number of standardizationefforts addressing MES functionality, automobile manufacturersare still struggling to reach a common understanding for the termMES and a clear functional design. The paper addresses this needby developing a functional reference model for MES in theautomotive industry based on a multiple case study approach. Thecase studies examine the design and implementation ofmanufacturing-related functionality in four leading automotivemanufacturing companies

Identifying suitable substrates for high-quality graphene-based heterostructures

We report on a scanning confocal Raman spectroscopy study investigating the strain-uniformity and the overall strain and doping of high-quality chemical vapour deposited (CVD) graphene-based heterostuctures on a large number of different substrate materials, including hexagonal boron nitride (hBN), transition metal dichalcogenides, silicon, different oxides and nitrides, as well as polymers. By applying a hBN-assisted, contamination free, dry transfer process for CVD graphene, high-quality heterostructures with low doping densities and low strain variations are assembled. The Raman spectra of these pristine heterostructures are sensitive to substrate-induced doping and strain variations and are thus used to probe the suitability of the substrate material for potential high-quality graphene devices. We find that the flatness of the substrate material is a key figure for gaining, or preserving high-quality graphene.Comment: 6 pages, 5 figure
