Abstract

In recessions, depository institutions accounted for most declines in mortgage flows. Recently, they partially offset their withdrawals from primary markets with accumulations of mortgage-backed securities. Increases in direct flows into agency and private pools also countered the declining flows elsewhere. As the less-procyclical secondary mortgage markets grew and matured, they increasingly s...

Fluid flow and heat transfer of viscoelastic materials in noncircular duct are complicated subject because of nonlinear behavior of rheological properties. In this paper flow and heat transfer of CEF fluids are studied with numerical modeling. Numerical solution is based on the artificial compressibility method and by using staggered mesh. The effect of secondary flows on the forced and natural...

BACKGROUND Cough is part of life in patients with cystic fibrosis (CF). Weak coughing may add to increased respiratory disease that affects the mechanical properties of cough in these patients. In this study, we investigated cough characteristics in relation to forced expiratory flow/volume indices in CF. METHODS This prospective study included 54 subjects (26 ± 10 y old) with CF. Similar ind...
