the phenomenological model of khossravi and connors (1992) has been adopted to calculate the electrophoretic mobility of drugs at different concentrations of solvents in a binary mixture. the accuracy and predictability of the model have been evaluated employing 14 experimental data sets by using average percentage mean deviation (apmd). the obtained apmd for correlative and predictive studies ...

aims : understanding the experiences of mothers could be as a strategy for the physicians, nurses who are working in nicu and administrators in the care centers in order to provide supports for parents, particularly mothers and an effective step to improve the quality of nursing care of premature infants and their parents.   methods : in this study, one of the qualitative research methods as de...

We propose that under certain conditions the universal open string tachyon can drive topological inflation in moduli stabilised frameworks. Namely, the presence of electric field in the world volume of the D-brane can slow down its decay leading to a phenomenological model of inflation. The conditions for inflation to take place are difficult to satisfy in the standard warped deformed conifold ...

The Jarlskog Invariant Jν−map of the neutrino mapping matrix is calculated based on a phenomenological model which relates the smallness of light lepton masses me and m1 (of ν1) with the smallness of T violation. For small T violating phase χl in the lepton sector, Jν−map is proportional to χl, but me and m1 are proportional to χ2l . This leads to Jν−map ∼= 1 6 √ me mμ +O ( √ memμ m2τ )

Based on a robust, phenomenological model for the growth of a system parameter, a relation is derived to test the evolution of such a parameter through several distinct stages. It is found that data defining the acknowledged major changes in the evolution of earth, the life on it, and cultural and technological growth, conform to this model. The nature of these altering events indicates that in...

We present an extension of the Tappin – Howard (TH) phenomenological model (Tappin and Howard, Space Sci. Rev. 147, 55, 2009) for coronal mass ejection reconstruction to use interplanetary scintillation g-map data. The necessary changes to the model are discussed. We then use the modified model to reconstruct two major interplanetary disturbances observed using the Cambridge 3.6 ha Array in Sep...

A comprehensive particle scale model for pyrolysis of biomass has been developed by coupling the reaction mechanisms and transport phenomena. The model, which also accounts for the combined effect of various parameters such as particle shrinkage and drying, was validated using available experimental data from the literature. The validated model was then used to study the effect of operating tem...
