THE EFFECT OF ULTRAFILTRATION TRANSMEMBRANE PERMEATION ON THE FLOW FIELD IN A SURROGATE SYSTEM OF AN ARTIFICIAL KIDNEY

The effect of ultrafiltration transmembrane permeation on the flow field in a surrogate system of an artificial kidney

Renal Replacement Therapies generally associated to the Artificial Kidney (AK) are membrane-based treatments that assure the separation functions of the failing kidney in extracorporeal blood circulation.Their progress Drinks from conventional hemodialysis towards high-flux hemodialysis (HFHD) through the introduction of ultrafiltration membranes c

Alterations in articular cartilage T2 star relaxation time following mechanical disorders: in vivo canine supraspinatus tendon resection models

Abstract Background The role of altered joint mechanics on cartilage degeneration in in vivo models has not been studied successfully due to a lack of pre-injury information.We aimed 1) to develop an accurate in vivo canine model to measure the changes in joint loading and T2 star (T2*) relaxation time before and after unilateral supraspinatus tend

Effect of gradient of stress intensity factor at a crack tip on fatigue crack growth and correction method for the effect

The stress intensity factor can be applied as an evaluation parameter of crack growth under small-scale yielding conditions.Moreover, the stress intensity factor corrected by the plastic zone correction can potentially be used as an evaluation parameter of crack growth for small-scale yielding criteria or beyond these criteria.In the previous study
