background: among diverse protein purification systems, affinity chromatography is the most attractive one in the purification process of coagulation factors. coagulation factor vii is a plasma serine protease that has a significant role in natural human hemostasis and its recombinant form such as aryoseventm, has been applied in clinical treatment of bleeding disorders. immunoaffinity chromato...

A bstract We introduce a new phenomenological tool based on momentum region indicators to guide the analysis and interpretation of semi-inclusive deep-inelastic scattering measurements. The tool, referred as “affinity”, is devised help visualize quantify proximity any experimental kinematic bin particular hadron production region, such that associated with transverse dependent factorization. ap...

The staining affinity of electron dense stains to mouse palatal elastic fibers and periodontal oxytalan fibers was assessed and compared. Tissues were stained routinely with uranyl acetate and lead citrate or with elastic tissue stains including: (1) silver tetraphenylporphine sulfonate, (2) tannic acid technique, and (3) a high iron diamine sequence. Staining results were assessed with an elec...

Nitrous oxide (N2O) is known as an important "greenhouse gas" but also a scavenger of hydrated electron and a source of OH radical. While there has been considerable interesting research on the electron attachment to N2O in the gas phase, the presence of solvent molecules will significantly alter the electron affinity, molecular structure and chemical reactivity of N2O. Ab initio calculations o...
