Leak rate

Leak-before-break assessments of piping in nuclear power plants require an accurate prediction of leakage rates through thin slits and the understanding of uncertainties. Two test rigs at the University of Stuttgart are dedicated to the measurement of flow rates in the order of the typical leak monitoring specification of 1 gal/min.

Laryngeal mask UNIQUE® (LMAU) is supraglottic airway device with good clinical performance and low failure rate. Little is known about the ideal position of the LMAU on the magnetic resonance imaging (MRI) and whether radiological malposition can be associated with clinical performance (audible leak) in children.

Systemic capillary leak syndrome is a rare disease with a high mortality rate. This syndrome is characterised by generalised edema, hypotension, hemoconcentration, and hypoproteinemia. The cause is the sudden onset of capillary hyperpermeability with extravasations of plasma from the intravascular to the extravascular compartment.

Urinary tract infections (UTI) are the second most common infections encountered in clinical practice and is associated with a high rate of morbidity and economic burden. Knowledge of the local antibiotic resistance patterns will help in providing empirical therapy and helps in prevention of resistance. This was a retrospective study conducted from January 2017 to December 2018 at a medical college in South India. Samples received included mid-stream clean catch urine, Catheterized urine, suprapubic aspirate.

The current water shortage in Egypt is 13.5 Billion cubic meter per year (BCM/yr) and is expected to continuously increase. Currently, this water shortage is compensated by drainage reuse which consequently deteriorates the water quality. Therefore, this research was commenced with the objective of assessing different scenarios for 2025 using the Water Evaluation and Planning (WEAP) model and by implementing different water sufficiency measures. Field data were assembled and analyzed, and different planning alternatives were proposed and tested in order to design three future scenarios.
