Das ‚effiziente Museum‘ im Widerstand gegen die ‚Diktatur der Wand‘
(2020-05-12)
Der vorliegende Beitrag geht von der Annahme aus, dass es sich bei der innovativen Ausstellungspraxis der Nachkriegszeit um eine ‚zweite Museumsreform‘ handelt, einen theoretischen Neuansatz, der die gegenüber der Vorkriegszeit abweichende Ausstellungspraxis der Epoche erst verständlich werden lässt. Zur Überprüfung dieser These liegt der folgenden Studie eine systematische Erfassung von museumstheoretischen Stellungnahmen in den Kulturzeitschriften der Nachkriegszeit in mehreren westeuropäischen Ländern zugrunde, ...

Dimensioning of Heat Pump Systems Based on Pinch Analysis and Energy Monitoring Data
(2018)
In this paper, typical process chains of metal processing/gear manufacturing are examined according to the pinch method with regard to their potential for heat recovery and their suitability for heat pump applications. The focus is on machine tools and parts washing machines as fluctuating heat sources and sinks. Heat sources at a low temperature level, such as the cooling of machine tools, are becoming increasingly important in contrast to conventional fossil waste heat sources due to the electrification of energy ...

How real are adjective order constraints? Multiple prenominal adjectives at the grammatical interfaces
(2019)
Adjective order restrictions on attributive adjectives (AORs) have been subject to debate in modern linguistic research for a long time. Most generally, the question whether AORs can be located in grammar as such in rule-based fashion is still unsettled. In the current paper, we largely argue against this view and claim that several of the core data to be explained are preferences based on norms rather than rules. A pragmatic explanation is offered to account for marked or apparently ungrammatical examples. First, ...

Evaluation of a Stratified Tank based Heat Recovery Loop via Dynamic Simulation
(2018)
Prerequisite for hot water recovery in the dairy and beverage industry is the use of heat storage, such as stratified tanks. Total Site Heat Integration enables the targeting of heat recovery potential, the concrete identification of suitable sinks and source profiles and the dimensioning of intermediate circuits and storages. For a cost and energy efficient storage, the aim to maintain stratification by suitable thermocline control management. Dynamic simulation enables a reliable estimation of energy savings and ...

Influence of the degree of crystallinity and the surface free energy on the adhesion properties of different PLA/PBS blends in multicomponent injection molding
(2020-01-10)
Biocomposites made of biodegradable polymers have grown in interest due to their environmentally friendliness, considering that non-biodegradable polymers waste conduces to pollution, displaying high environmental impact in climatic changes. Therefore, in the presented study, biodegradable Poly (lactic acid) (PLA) and poly (butylene succinate) (PBS) were investigated as a series of PLA/PBS melt-blending compounds with the weight ratios of 50/50, 60/40, 70/30, 80/20 and 90/10. In a two-component injection molding ...

Relaxation properties of polyoxymethylene and ethylene–octene copolymer blend in solid and melt states
(2012-08-30)
Rheological properties of polyoxymethylene (POM) and ethylene–octene copolymer (EOC) in solid and melt states were investigated. Blends were prepared with a twin screw extruder at broad component wt-to-wt ratios (10, 30, 50, 70, 90 wt% of EOC). The morphology as well as calorimetric, rheological, and elastic properties of the blends were studied. The investigation showed that POM/EOC blends were heterogeneous in nature and had a broad phase transition region between 30 and 70 wt% of POM. Because during processing ...

Predictive Simulation-based Optimisation of Cooling System Including a Sprinkler Tank
(2018)
Prerequisite for an efficient cooling energy system is the knowledge and the optimal combination of different operating conditions of individual compression and free cooling chillers. The performance of cooling systems depends on its part load performance and its condensing temperature, which are often unknown. Recorded energy data remains unused and manufacturers' data significantly differs from the real performance. For this purpose, manufacturer and real data are combined and continuously adapted to form partial ...

Carbon footprint for wheat and corn under Egyptian condition
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-12-26)
Egypt agriculture is facing a great joint challenge of ensuring food security and mitigating greenhouse gas emissions under climate change. Characterizing the carbon footprints of crop production by life cycle analysis is be critical for identifying the key measures to mitigate greenhouse gas emission while sustaining crop productivity in the near future. Agriculture contributes a significant share of greenhouse gas emissions and concurrently represents a carbon dioxide (CO2) sink; it thus has two fold opposing impacts ...

Entwicklung und Potentiale digitaler Raumforschung
(2018)
A rise of digital methods paves the way for new opportunities but also poses risks for spatial planning and research. Academic training of planners rarely supports the testing and understanding of digital research tools. In this article we analyze best-practice examples, review questions of data ethics and provide recommendations for incorporating the digital-turn in the academic teaching practices.
