We generalize a size-biased distribution related to the Riemann xi function using work of Ferrar. Some analysis and properties this more general are offered as well.

in our previous work, the effect of use of a water soluble cdi/nhs system as nontoxic cross-linking agent on fabrication of gelatin nanoparticles was investigated. in this research, the effect of variation in some synthetic parameters of gelatin nanoparticles cross-linked by cdi/nhs system such as type of gelatin and formulation of cross- linking agent on their size and distribution was examine...

Predicting population extinctions is a key element of quantitative conservation biology and population ecology. Although stochastic population theories have long been used to obtain theoretical distributions of population extinction times, model-based predictions have rarely been tested. Here I report results from a quantitative analysis of extinction time in 281 experimental populations of wat...

in suspension polymerization, particle size distribution of polymer is the outcome of dynamic equilibrium between the break up and coalescence phenomena. the rates of break up and coalescence and consequently polymerization stability depend on several parameters, the most important of which are type and concentration of stabilizer. in this study, the effects of type and concentration of stabili...

The determination of the required sample size is always an important step during planning quality research for a quantitative study. researchers need to have sound prerequisite knowledge inferential statistics concept determining minimum requirement and its estimation because insufficient may not be able answer questions large wastage resources, add complexity, take more time Both situations ar...
