Summary: As large renewable capacities penetrate the European energy system and the climate faces significant alterations, the future operation of hydropower reservoirs might deviate from today.In this work, we first analyze the changes in hydropower operation required to balance a wind- and solar-dominated European energy system.Second, we apply r
Introduction: Recent studies have shown that frozen fruit juices cause a greater drop in dental plaque and salivary pH.Since ice candies contain ingredients such as citric acid, sugar and flavouring substances similar to juices and it in frozen form, they may also have the potency to erode.Aim: To evaluate the erosive potency of commercially availa
This paper describes the analysis and investigation of Tea Towel the causes of the failure of an hydraulic press jaw face grip.Analysis of the fractured surfaces indicated the creation of cracks due to stress concentrators as a result of defective design.On the other hand, metallographic examination revealed the presence of aligned clusters of prim
Primordial black Pajamas S holes (PBHs) from the early Universe constitute a viable dark matter (DM) candidate and can span many orders of magnitude in mass.Light PBHs with masses around 1015 g contribute to DM and will efficiently evaporate through Hawking radiation at present time, leading to a slew of observable signatures.The emission will depo
Considering that the driver and passengers need different display content in the vehicle display, we propose a dual-view and multi-content head-up display (HUD).Based on the angle selectivity of volume holographic grating (VHG), the multiplexed VHGs diffract light beams at different angles to achieve dual-view display.Based on the wavelength select
