Die Verstärkung von Spritzgussteilen mit Faserhalbzeugen gewinnt immer mehr an Bedeutung. Für die Einsatztauglichkeit derartiger Bauteile ist die Verbundhaftung zwischen den angespritzten Strukturen und den Faserhalbzeugen essentiell. Der Vortrag befasst sich mit den äußeren und prozesstechnischen Einflüssen zu Erhöhung der Verbundhaftung auf Faserhalbzeugen. Zudem wird ein Einblick in die Prüf und Anlagentechnik in diesem Bereich gegeben.
Differences in road infrastructure, such as capacity, congestion, speed limits affect the productivity and the costs of short-distance freight operations. This article introduces a novel methodology that is based on navigation service data to measure the effects in terms of cost per kilometer using navigation and shipment data. The methodology is applied to five terminals of a forwarding cooperation and has been able to document significant differences in cost per kilometer across the terminals. The research results can be used by logistics service providers to better understand how productivity and thus profitability is affected by the quality of the transportation infrastructure in the particular areas they operate in. Furthermore, the insights will help these companies for better, i.e. cost-based pricing and will allow to document why and where prices need to be adapted.
This research explores logistics-related leverages in the responsibility of retailers for improving the environmental performance of a Fast Moving Consumer Goods (FMCG) distribution network. We examine opportunities for modifying the network carbon footprint by changing network design variables. To do so, a quantitative distribution network model is established, and 150 scenarios are calculated by modifying real-world shipment data from an existing multinational FMCG manufacturer. Four distribution variables are identified for a many-to-many and a hub-and-spoke network structure. Two variables affect the distribution network and two interfere in the shipment structure by manipulating weight and/or the delivery date. This research sheds light on the extent of the changes in greenhouse gas (GHG) emissions of the distribution network that result from modifications in the logistics variables. The greatest effect on the quantity of GHG emissions can be observed when an anticipation horizon for orders is introduced. When shipments are consolidated and delivered only weekly or biweekly from the manufacturer to the retailers, GHG emissions drop significantly. Another opportunity for retailers to cut down GHG emissions is based on the concept of minimum order quantities where shipments to a retailer location are bundled until a certain weight is reached. Additionally, total GHG emissions of distribution may be reduced by raising the tonnage limit, thereby triggering direct shipments between the manufacturer’s facilities and the retailer locations, or by raising the tonnage limit, which triggers direct shipments in the logistics service provider network. The extent of GHG reduction is assessed for all investigated variables.

Numerous studies from the past five decades have shown that selective retrieval of some studied items can impair recall of other items. This chapter reviews more recent work, in which it is demonstrated that selective memory retrieval has two faces and that it can both impair and improve recall of other items. In this recent work, participants' access to study context during selective retrieval was experimentally manipulated and it was examined whether such manipulation influences the effects of selective retrieval. Access to study context was manipulated using listwise directed forgetting, context-dependent forgetting and time-dependent forgetting. The results consistently showed that selective retrieval impairs recall of other memories if access to study context during retrieval is largely maintained, but that selective retrieval can improve recall if study context access is impaired. The findings are explained by a two-factor account, which claims that, in general, selective retrieval does not only trigger inhibition and blocking but also triggers context reactivation processes. The proposal is that primarily inhibition and blocking operate when study context access during selective retrieval is largely maintained, whereas primarily context reactivation processes operate when study context access is impaired. Current findings on the two faces of selective retrieval are well consistent with this theoretical view.
