The Small Head Criterion in Hydropower and understanding the Dimensions of Renewable Energy with Water Resources
The Habilitation thesis unravels the questions in defining the head parameter for small hydropower in order to meet the challenges of diverse end use applications with electricity on one side and water supply on the other. The thesis sets a limiting criterion between 1.5 and 5 meters to explore both conventional and unconventional turbomachinery. However, with respect to water supply as end use, it strongly advocates non turbine technologies like ram pump that are more efficient at lower flows
18F-FDG avid Sclerosing Angiomatoid Nodular Transformation (SANT) of spleen on PET-CT β a rare mimicker of metastasis
Sclerosing Angiomatoid Nodular Transformation (SANT) is a rare benign vascular tumor of spleen. It consists of multiple angiomatoid nodules surrounded by dense fibrous tissue that often coalesces centrally to form a scar, which is considered to be a characteristic feature. These are usually asymptomatic and incidentally detected on imaging for other underlying pathology. SANTs can be 18F-Fluorodeoxyglucose (18F-FDG) avid on positron emission tomography-computed tomography (PET-CT) and thus can lead to false positive finding in oncological patients
