Water-hammer is a transient condition which may occur in a network as a result of rapid or slow valve closures, pump failures, changes in turbine loading, etc. It creates high and low pressure waves which travel along the system and decay as a result of wall shear stress. Comparison o experimental and theoretical results revealed the failure of steady or quasi-steady models in correctly predict...

 Production data analysis techniques have been widely used for estimating reservoir properties such as gas in place and average pressure. Knowledge of this information is crucial for proper reservoir management. The present study discusses the roadmap, challenges and uncertainties for analyzing production data in an Iranian gas-condensate offshore field. This work is an integrated study in...

Background and Aim: Spinal manipulation is a treatment modality in the management of patients with pain in the neck, low back or pelvic disorders. The objective of this research was to determine the effects of sacroiliac joint manipulation on selected electrophysiological parameters including pressure pain thresholds (PPT) and Tibial nerve Hoffmann's reflex (H-reflex) amplitude. Materials and M...

a water distribution network is subjected to various abnormal conditions such as pipe breaks, pump failures, excessive demands etc. in the design period. under such conditions, the network may not be able to meet required demands at desired pressures, and becomes deficient. traditional network analysis assumes nodal demands to be satisfied and available nodal pressures are calculated. however, ...
