Dual scattering channel (DSC) schemes generalize Johns’ TLM algorithm in replacing transmission lines with abstract scattering channels in terms of paired distributions. A well known merit of TLM schemes is unconditional stability, a property generally drawn upon passivity of linear transmission line networks. So the question arises, if DSC algorithms remain stable in a neat sense. It is shown ...
A class of high-order lowpass filters, the discrete singular convolution (DSC) filters, is utilized to facilitate the Fourier pseudospectral method for the solution of hyperbolic conservation law systems. The DSC filters are implemented directly in the Fourier domain (i.e., windowed Fourier pseudospectral method), while a physical domain algorithm is also given to enable the treatment of some s...

Thermal analysis (DSC: Differential Scanning Calorimetry and TGA: Thermogravimetric Analysis) of SEBS blends have been studied in this paper. SEBS blends were made using two transparent SEBS commercial grades with extreme hardness values. The first thermal property determined in SEBS blends was the evaluation of the thermal degradation at high temperatures (DSC). Another thermal property of the...
Introduction Dynamic susceptibility contrast (DSC) MR perfusion is based on the indicator dilution theorem for non-diffusible tracers.[1,2] A common misconception is that tracer recirculation cannot occur in order to make use of the underlying theory (i.e., analysis of the tracer kinetics must be “firstpass”).[3-13] As a result, there have been a number of approaches suggested for removing trac...

The improved yield strength of annealed dispersionstrengthened copper (DSC) over conventional OFE copper makes it a possible candidate for use in extremely high potential gradient particle accelerator structures where stability is of critical importance. Test brazes of such structures show that the surface of DSC is not readily wetted by conventional goldbased braze alloys used for copper. Surf...
buccoadhesive drug delivery systems have distinct advantages in comparison with oral administration. plant exudates like gum or mucilage are being studied for their use as pharmaceutical adjuvant. the aim of this study is to evaluate the properties of the plantago major seed mucilage as a mucoadhesive agent and propranolol hydrochloride is chosen as a model drug. mucoadhesive tablets of propran...
سابقه و هدف: پتانسیل سیستم های مایع به جامد (liquisolid) جهت افزایش ویژگی های انحلال داروهای نامحلول در آب، در سال های اخیر مورد بررسی قرار گرفته و به اثبات رسیده است. در این مطالعه تاثیر حلال غیر فرار گلیسرین بر فرمولاسیون های مختلف از قرص های مایع به جامد ایندومتاسین مورد بررسی قرار گرفت.مواد و روش ها: در این پژوهش از آویسل (به عنوان حامل) و سیلیکا (به عنوان عامل پوشاننده) با نسبت 20:1 استفاد...
in this work we sought to determine whether vesicles (liposomes/niosomes) were able to enhance finasteride concentration in the dermis layer, including the pilosebaceous units (psu). such enhancement could be beneficial in the treatment of some androgen-related skin disorders. hamster flank skin was used to study 3hfinasteride permeation via vesicles and a hydroalcoholic solution (ha). the dru...
