Techno-Economic Analysis of Packed Bed Type Thermal Batteries for Surplus Renewable Energy Storage
Abstract: Low carbon electricity from renewables will form the bed rock of the energy transition necessary for climate change mitigation. However, variable renewable generators suffer from intermittency and variability – there can be large surplus power available at times which cannot be dispatched to the grid. At many times, the practice is to curtail surplus renewable output, which is wasteful and not economic. There are also phases when generation is not …

Peri-implant Inflammation Defined by the Implant–Abutment Interface
Abstract: An interface of implant-abutment at the alveolar bone crest is allied with sustained peri-implant inflammation; though, whether extent of inflammation is correspondingly reliant on interface position remains unknown. This study compared the distribution and density of inflammatory cells surrounding implants with a supracrestal, crestal, or subcrestal implant-abutment interface. All implants established a parallel pattern of peri-implant inflammation: neutrophilic polymorphonuclear leukocytes (neutrophils) extremely collected at or proximately coronal to the interface. …
