A Laboratory Study Attempt of Flow and Energy Dissipation in Stepped Spillways
Journal of Engineering, 2016 A new laboratory study conducted on stepped spillways in order to investigate their efficiency of dissipating flow energy. All previous study on stepped spillway indicated that the flow energy dissipation decreased as increasing in discharge.

Public Safety and Unauthorized Extreme Activities at Spillways
, 2018 One very important purpose for reservoirs is the recreational opportunities they provide to the general public. Unfortunately, some people engage in highly dangerous or extreme activities at dams and spillways that occasionally result in severe injury or

Embankment dam spillways and energy dissipators
, 2013 For the last fifty years, the design floods of a number of embankment dams were re-evaluated and the revised spillway outflows are often larger than the original design discharges.

A high‐fat diet with vitamin D and propylthiouracil produces a pro‐atherogenic phenotype in rats
Animal Models and Experimental Medicine, EarlyView.Male Sprague–Dawley rats received a cholesterol‐rich high‐fat diet supplemented with vitamin D and propylthiouracil for 11 weeks. The model induced dyslipidemia (increased total cholesterol/low‐density lipoprotein, decreased triglycerides), inflammation (increased interleukin‐6 and serum amyloid A), hypercalcemia, and reduced circulating endothelial ...

By-wash spillways for farm dams
, 1966 Model studies formed a basis for investigating the hydraulics of bywash spillways for farm darns When constructed in natural earth such spillways are trapezoidal in cross section The surface of the spillway needs protection from scour and this protection

British Educational Research Journal, EarlyView.Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.
