Transition models for turbomachinery boundary layer flows : a review [PDF]

open access: yes, 2017
Current models for transition in turbomachinery boundary layer flows are reviewed. The basic physical mechanisms of transition processes and the way these processes are expressed by model ingredients are discussed.

Surface-bound heparin fails to reduce thrombin formation during clinical cardiopulmonary bypass [PDF]

open access: yesThe Journal of Thoracic and Cardiovascular Surgery, 1996
The hypothesis that heparin-coated perfusion circuits reduce thrombin formation and activity; fibrinolysis; and platelet, complement, and neutrophil activation was tested in 20 consecutive, randomized adults who had cardiopulmonary bypass. Twenty identical perfusion systems were used; in 10, all blood-contacting surfaces were coated with partially ...

Ionizing radiation impact on the mechanical properties of a wood-plastic composite: a review [PDF]

open access: yes, 2020
This paper reviews the effect of radiation on the mechanical properties of WPC. WPC can be defined as mixture of wood in a polymer matrix. Composite that used in this research mainly consists of 40% polyethylene (PE), 50 % wood fiber and the rest is ...

Twisty itsy bitsy topological field theory [PDF]

open access: yes, 2014
We extend the topological field theory (``itsy bitsy topological field theory"') of our previous work from mod-2 to twisted coefficients. This topological field theory is derived from sutured Floer homology but described purely in terms of surfaces with ...

Compressed absorbing boundary conditions via matrix probing

open access: yes, 2014
Absorbing layers are sometimes required to be impractically thick in order to offer an accurate approximation of an absorbing boundary condition for the Helmholtz equation in a heterogeneous medium.

Long-term outcomes of omniflow II biosynthetic vascular graft in lower extremity arterial revascularization [PDF]

open access: yes, 2018
Background: This study aims to evaluate the patency rates and long-term outcomes of femoro-popliteal bypass procedures with Omniflow II biosynthetic vascular grafts in patients with occlusive vascular disease.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Evaluation of a fine-spaced angled rack with surface bypass in providing safe and timely downstream passage for salmon smolts and silver eels

open access: yesKnowledge and Management of Aquatic Ecosystems, 2023
Hydropower production can cause migration delay and fish mortality, impeding the safe and timely downstream migration of diadromous fish, such as Atlantic salmon (Salmo salar) and silver eels (Anguilla anguilla).

Road and bridge construction across gypsum karst in England [PDF]

open access: yes, 2002
Gypsum karst problems in the Permian and Triassic sequences of England have caused difficult conditions for bridge and road construction. In Northern England, the Ripon Bypass crosses Permian strata affected by active gypsum karst and severe subsidence ...

Effects of Graphite Surface Roughness on Bypass Flow Computations for an HTGR [PDF]

open access: yesVolume 5: High-Pressure Technology; Nondestructive Evaluation; Nuclear Engineering, 2011
Bypass flow in a prismatic high temperature gas reactor (HTGR) occurs between graphite blocks as they sit side by side in the core. Bypass flow is not intentionally designed to occur in the reactor, but is present because of tolerances in manufacture, imperfect installation and expansion and shrinkage of the blocks from heating and irradiation.
