Is the free cash flow hypothesis valid in Turkey?
This study tests the validity of the free cash flow hypothesis in the context of firms traded on Borsa Istanbul. The study applies a panel regression to a data set composed of 1267 observations from 227 companies during the period 2008–2014.

Evaluation of the hydraulic behavior of the composite hydraulic structure considering a bed flume with special obstacle [PDF]
The experimental simulation between the composite hydraulic structure and the found obstacles in the downstream region is a challenging process due to the energy losses and kinematic dissipation. The current work focuses on a comparative analysis of free

A Note on the Discharge over Full-width Rectangular Sharp-crested Weirs and Weirs of Finite Crest Length [PDF]
The head-discharge relationship for sharp-crested weirs is developed based on the energy consideration upstream and at the crest of the weir. The discharge for weirs of finite crest length is estimated by correlating the critical depth and total energy ...
