Katalog zur gleichnamigen Ausstellung im alten Gasometer in Oberhausen. "Ein starkes Stück Deutschland" - mit diesem Motto hat Nordrhein-Westfalen in den letzten Jahren für sein im Umbruch befindliches Kernland, das Ruhrgebiet, geworben. Die Ausstellung zeichnet ein facettenreiches, umfassendes Bild von Geschichte und Gegenwart des "Reviers" und seiner Menschen. Dunkle Punkte werden dabei nicht ausgeklammert. Der Katalog bietet neben informativen Einführungsartikeln ausführliche Beschreibungen aller Exponate mit Abbildungen in Auswahl. Ein bleibendes Dokument über die Ausstellung hinaus. (LK/AC: Krause)

Assessing the chronic toxicity of a compound to developing honey bees (Apis mellifera L.) has proven to be a challenge since the mid-2000s. Such data are requested by global regulatory authorities so they can evaluate the risk of compounds to larval honey bees when exposure is likely to occur in the environment. Poor test performance has led to frequent study failures and data uncertainty. Here we highlight a recent effort by the Pollinator Research Task Force (PRTF)1 to validate the use of a method for evaluating the chronic toxicity of a compound (e.g., a pesticide) to an immature honey bee for use in a risk assessment. A ring test protocol was selected and based upon the current OECD guidance document No. 2392 with amendments developed at the University of Florida (Schmehl et al. 2016)3. Fifteen independent laboratories on three continents representing government, academia, and industry followed the same testing protocol to: 1) determine if test performance is robust across different geographic regions and different laboratory personnel and 2) identify limitations associated with the methodology. The control performance criteria for a valid test according to OECD GD 239 is ≥ 85% survival at the end of the larval development and ≥ 70% survival through adult emergence. Thirteen trials (81.3%) satisfied the validity criteria and the test design's performance was determined adequate for regulatory testing. The toxic reference chemical (dimethoate) had a consistent response with a 22-day EC 50 range of 8-22 μg active substance (a.s.)/g diet. An acetone concentration at the maximum concentration allowed by the OECD GD 239 (2% acetone) was observed to be problematic to test performance. In conclusion, the ring test methods based upon the OECD GD 239 demonstrated that the repeat (chronic) exposure of a compound on developing bees can be successfully conducted.

La evolución de la ciudad postindustrial se reestructuró a partir de nuevas actividades, generalmente de servicios, en espacios donde previamente se habían desarrollado procesos de desindustrialización. El objetivo de este artículo es analizar como el patrimonio industrial se convierte en un elemento competitivo de la ciudad del conocimiento, dónde el sector público presionado por los movimientos ciudadanos, introduce políticas de protección de este patrimonio en favor de la construcción de la ciudad cultural. La pregunta estructural es analizar cómo se produce el patrimonio industrial, cómo se consume, y cuáles son los agentes que participan en ambos procesos; y cómo el patrimonio deviene un elemento básico del proceso de revitalización económica y de compacidad urbana en el Poblenou-22@Barcelona; finalmente se postula como esta estrategia representa un Nuevo Modelo Barcelona. La política de clústeres en el área del Poblenou, donde se localiza el plan 22@Barcelona, representó una propuesta innovadora para la transformación urbanística, económica y social de la ciudad de Barcelona ; Poblenou's intense development has been a result of the urban project 22@Barcelona (2000); which revitalized urban morphology and the area's previous economic downturn, during period 2000-2013. This article analyzes how the industrial heritage remaining in Poblenou becomes a competitive element of the project Barcelona city of knowledge, where civil society forced the public sector to introduce policies to protect this heritage for the cultural construction of the city. The structural question is to analyze how the industrial heritage was produced, how it was consumed, and which agents were involved in both processes. In addition, the focus of this paper would be to study how heritage becomes a basic element of the process of economic revitalization, of symbolic projection and of urban compactness in the Poblenou-22@Barcelona. In that, there remains an unanswered question which is the focus of this paper of whether this process represents a New Barcelona Model. The economic cluster's political approach in this area represents an innovative strategy for the urban, economic and social transformation of the whole City of Barcelona
