Preserving the National Blood Supply
Hematology, 2001 AbstractThis paper examines the current state of the blood supply in the US and focuses on the potential for augmenting blood availability by attention to the iron status of donors. Increasing demands are being made upon the national blood supply as rates of blood donation are declining, in part because of the loss of blood donors as a result of ...

Flow competition between hepatic arterial and portal venous flow during hypothermic machine perfusion preservation of porcine livers [PDF]
, 2012 Hypothermic machine perfusion (HMP) is regarded as a better preservation method for donor livers than cold storage. During HMP, livers are perfused through the inlet blood vessels, namely the hepatic artery (HA) and the portal vein (PO.

A new two-dimensional blood flow model with arbitrary cross sections [PDF]
arXiv, 2021 A new two-dimensional model for blood flows in arteries with arbitrary cross sections is derived. The model consists of a system of balance laws for conservation of mass and balance of momentum in the axial and angular directions. The equations are derived by applying asymptotic analysis to the incompressible Navier-Stokes equations in narrow, large ...

Non-uniform force allocation for area preservation in spring network models [PDF]
, 2016 In modelling of elastic objects in a flow such as red blood cells, white blood cells, or tumour cells, several elastic moduli are involved. One of them is the area conservation modulus. In this paper, we focus on spring network models and we introduce a new way of modeling the area preservation modulus.

Gravity influence in one-dimensional blood flow modeling [PDF]
arXiv, 2023 One-dimensional blood flow model accuracy has been verified in many studies. This work is about introducing gravity into a one-dimensional model. For this purpose, gravitational force was introduced into the existing model. The boundary conditions must also be adjusted to account for gravity.
