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 ...

ôbjective: presently, the issue of attempted suicide now poses one of the major challenges facing the health-care providers in ïran and other countries. âlthough in previous years, the number of people entering to hospital emergency departments after deliberately taking overdoses or injuring themselves has been steadily increased in ïran, however, there is less attention to the issue of suicide...

Qualitative research comes with various forms and faces, and, fortunately, there now exist numerous books that deal with issues related to qualitative research. Not that many books, however, deal explicitly and extensively with the transformation and application of principles of phenomenology and hermeneutics. Reflective Lifeworld Research is written as a response to this apparent need. It is, ...

Phenomenology questions the basic foundations of Modernity. In particular, it challenges Descartes‘ attempt to found the scientific method with absolute certainty. Phenomenology is defined by the work of Husserl, Heidegger, and Merleau-Ponty. Even though each of them developed their own way within Phenomenology, their theories are determined by a critique of the Cartesian method. For them, Desc...

We discuss the possibility of a smooth transition from the preto the post-big bang regime, in the context of the lowest-order string effective action (without higher-derivative corrections), taking into account with a phenomenological model of source the repulsive gravitational effects due to the back-reaction of the quantum fluctuations outside the horizon. We determine a set of necessary cond...

The paper shows that a phenomenological model of inertial induction based on a proposed extension of Mach’s Principle can produce the observed cosmological red shift in a quasi-static infinite universe. Unlike all other theories (except the Doppler effect) to explain the observed red shift this model can be verified from other local effects predicted by this mechanism. A number of such phenomen...

The spin dynamics of the ferromagnetic pinned layer of ferro-antiferromagnetic coupled NiFe/MnNi bilayers is investigated in a broad frequency range (30 MHz-6 GHz). A phenomenological model based on the Landau-Lifshitz equation for the complex permeability of the F/AF bilayer is proposed. The experimental results are compared to theoretical predictions.

We study light-cone distribution amplitudes of heavy-light systems, such as a B-meson. By an explicit computation, we determine how two-parton distribution amplitudes mix with threeparton ones at one loop: φ+ is shown to mix only into itself, whereas φ− mixes with the difference of three-parton distribution amplitudes ΨA −ΨV . We determine the corresponding anomalous dimension and we check the ...
