Studying bubble–particle interactions by zeta potential distribution analysis

Effective size and zeta potential of nanorods by Ferguson analysis.

The effective hydrodynamic size and free mobility of particles of varying aspect ratio were evaluated by Ferguson analysis of gel electrophoresis. The ligand layer thickness was estimated from the difference between the effective size and the size of the metal core from TEM imaging. The zeta potential of the particles was calculated from the Ferguson analysis result by applying conventional ele...

modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...

Distribution of irrational zeta values

In this paper we refine Ball-Rivoal’s theorem by proving that for any odd integer a sufficiently large in terms of ε > 0, there exist [ (1−ε) log a 1+log 2 ] odd integers s between 3 and a, with distance at least aε from one another, at which Riemann zeta function takes Q-linearly independent values. As a consequence, if there are very few integers s such that ζ(s) is irrational, then they are ...

Potential Drug Interactions in War-Injured Veterans

Drug-drug interaction (DDI) is one of the most important problems in the treatment of patients suffering from different chronic intractable diseases. The war-injured veterans are one of the groups that are prone to chronic refractory diseases. This investigation was conducted on war-injured veterans treated in a multi-disciplinary clinic in Tehran. Using Poisson model, a total of 150 patients w...
