The hack is to use the total reflection from the low density material (which do not suffer much the photoelectric absorption) at low energy, while the photons at high energy are reflected by the high density material. Now for several future projects like e.g. ATHENA and eXTP it is foreseen the use of low density overcoatings that will importantly increase the effective area at low energy. In this poster we will discuss about the use of materials different from the ones considered so far, in particular based on a thin layer of Chromium followed by another layer of a Carbon-like material, and of novel approaches for their application.

T2 - Weidener Diskussionspapiere Nr. 67 N2 - This paper conducts a thorough data analysis using cross-sectional data from a study carried out in Mexico including over 16,500 observations. In the study, clusters were selected in areas Compartamos Banco, a Microfinance institution (MFI), has not lent in before. The clusters were randomly assigned to either the treatment or the control group. The analysis suggests that Microfinance has a significant positive effect on school and food expenditure but no apparent effect on entrepreneurship. Using regression analysis, a significant positive effect on women’s empowerment and its positive effect on total consumption is found.

Konzertiert. Aktiv - Die Transformation der Arbeitswelt gemeinsam gestalten N2 - Der vorliegende Text basiert einerseits auf den Ergebnissen von studentischen Arbeiten, welche im Sommersemester 2018 und im Wintersemester 2018/2019 am IMI erstellt wurden. Weiter trafen sich die Autoren Prof. Dr. Georg Rainer Hofmann und Meike Schumacher (beide TH Aschaffenburg) über ein Jahr ca. alle zwei Monate zu jeweils zweistündigen Gesprächen mit Vertretern der KAB (Herr Joachim Schmitt, Herr Peter Hartlaub) und der IG Metall (Herr Percy Scheidler, Frau Manuela Lüft, Herr Simon Kruppa), sowie Herr Rudi Grossmann, ehemaliger Kreisvorsitzender des Deutschen Gewerkschaftsbundes (DGB), der auch Mitglied der KAB ist. Es wurden in diesen Gesprächen eine Vielzahl von Erkenntnissen und Perspektiven zum Thema der „Neuen Arbeitswelt“ identifiziert. Frau Lucia Falkenberg, Chief People Officer (CPO) und Leiterin der Kompetenzgruppe New Work des eco – Verband der Internetwirtschaft e. V. vertritt in der vorliegenden Studie die Perspektive der Arbeitgeber in der Digitalen Transformation (Kap. 2.4); die Arbeitgeber haben das Problem der hinreichenden Attraktivität ihrer Unternehmen bei der Gewinnung qualifizierter Fachkräfte zu gegenwärtigen. Die Beteiligten fanden diese neuen Aspekte – insbesondere weil sie aus verschiedenen Bereichen des Bemühens um eine Humanisierung der Arbeitswelt stammen – einer Dokumentation wert. Aus diesem Grund wurde eine Ausarbeitung – als Diskussionsangebot und -beitrag – vorgenommen, in die sowohl die veränderten Rahmenbedingungen der Arbeitswelt, als auch einige Überlegungen zu politischen Handlungsoptionen geflossen sind.

At the same time as (erroneously) treating them like conventional cartel prices, they have also mandated an upper ceiling for them — effectively legitimising the concept. As this paper demonstrates, classifying MIFs with standard cartel pricing is a categorical error. A capped MIF is simply one ingredient of a well-functioning card payment system. Indeed, without MIFs, payments markets suffer free-rider problems and high transaction costs. To illustrate how MIFs curtail the tendency of prices to move upward, the paper examines the German ATM system before 2011. Finally, the paper argues that the current regulatory approach may lead to the demise of those European card schemes that are currently under pressure from MasterCard and Visa.

Durch Kombination dieser fluktuierenden Erzeugung zum Beispiel aus Photovoltaik oder Windenergie mit flexibler Erzeugung aus Biogas in einem virtuellen Kraftwerk können diese Herausforderungen jedoch gelöst werden. Geeignete Technologien und IKT-Infrastrukturen vorausgesetzt, können erneuerbare Energien damit künftig zu einer verlässlichen Stromerzeugung werden.

Due to the high heterogeneity degree in a digester the sampling errors are larger than the analysis error, making representative sampling a prerequisite for successful process control. In our system, samples are automatically processed, generating a higher density of data and avoiding human error by sample manipulation. The combination of a representative sampling system with a commercial automate titration unit generates a robust online monitoring system for biogas plants. The system was successfully implemented in an operating biogas plant to control a feeding-on-demand biogas system.
