The lymphoid system normally mounts damaging responses to infectious pathogens while avoiding equally damaging responses to self. A notable number of antibodies to self antigens are formed but normally remain at levels below the damaging threshold, only temporarily rising to damaging levels during protective responses against infectious nonself. Many mechanisms regulate the level of autoantibod...

membrane technology is used to separate water or solvents from salts or pollutants. this technique could be used for water treatment. for using of polyether sulfone (pes) hollow fiber membranes in water treatment processes, the pes hollow fiber membranes were prepared by dry-wet spinning method and heated in an oven at: 120°c, 150°c and 180°c. the effect of heating on performance of membranes w...

large unilamellar liposomes and multilamellar vesicles consisting of dmpc interacted with cationic phosphorus-containing dendrimers cpds g3 and g4. dsc and ζ -potential measurements have shown that liposomal-dendrimeric molecular recognition occurs due to the interaction between the complementary surface groups. calorimetric studies indicate that the enthalpy of the transition of the lipids tha...

Shape optimisation is utilised to generate damage resistant structures. By means of a variational approach, the analytical gradients for an elasto-plastic material model with regularised properties are derived. Due complexity underlying model, application approach requires additional handling history field. The then used Sequential Quadratic Programming (SQP) which applied shape and thus genera...

This study reports on the influence of nitrogen plasma exposure H-diamond (100) adsorption adventitious oxygen, bonding, and thermal stability studied by X-ray photoelectron spectroscopy. The nitrogen-plasma exposures include microwave (MW) radio frequency (RF) (at pressures: 3×10-2 (damaging) 7×10-2 Torr (non-damaging)) plasmas. largest amount oxygen ambient occurs damaging RF(N2) (O=2.8 at.%)...
