Consider a measurable space with an atomless finite vector measure. This measure defines a mapping of the σ-field into an Euclidean space. According to the Lyapunov convexity theorem, the range of this mapping is a convex compactum. Similar ranges are also defined for measurable subsets of the space. Two subsets with the same vector measure may have different ranges. We investigate the question...

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...

in this study, response surface methodology was used to determine the optimum raw sugar beet juice purification process conditions using bentonite to produce inverted liquid sugar. for this purpose, impact of factors on the purification process such as bentonite concentration (1-5 gr/li), ph (3.5-6) and temperature (35-95 ˚c) was investigated. for each response, a second-order polynomial model ...

the histone-like protein hu is the most-abundant dna-binding protein in bacteria. the hu protein non-specifically binds and bends dna as a hetero- or homodimer, and can participate in dna supercoiling and dna condensation. it also takes part in dna functions such as replication, recombination, and repair. hu does not recognize any specific sequences but shows a certain degree of specificity to ...

lactide was synthesized by reverse polymerization of low molecular weight poly(lactic acid) with two different molecular weights:1500 and 2500. two different lactide purification processes such as: recrystallization in ethyl acetate and washing the crude lactide with ether before recrystallization in ethyl acetate were evaluated. it has been demonstrated that increasing the molecular weight of ...

There has been a lot of news coming out of Iraq in recent decades, but most of it ignores the situation for people on the ground: ordinary men, women and children who continue trying to live their lives in spite of wars, economic sanctions, violence, and social, political and cultural collapse. The challenges of maintaining and sustaining health in an environment where everything-the human spir...

As a strong oxidizer, ozone has much damage to a variety of things. So when using ozone to execute purification, we need to monitor and control its concentration strictly. The monitoring and control of the ozone concentration can greatly reduce the damage caused by ozone concentration. Thus, multi sensor information fusion technique is applied, and then fuses the gathered multi-sensor data info...
