Geometry Impact on Flow Characteristics Inside River Intakes [PDF]

The Egyptian International Journal of Engineering Sciences and Technology
Intake is an open channel that usually has a non-uniform flow along its length. The pattern of the flow in lateral intakes is fully three-dimensional. Velocity and direction change in lateral intakes lead to non-consistency and recirculation of the flow.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Numerical comparison between the Boltzmann and ES-BGK models for rarefied gases [PDF]

, 2000
Projet M3NRarefied gas flows obey to the Boltzmann equation, but numerical simulations of this equation are not always possible, so that simpler models have been introduced. The ES-BGK equation is one of these models.
