background quince seed mucilage biopolymer (qsmb), famous for ameliorating coughs and controlling asthma symptoms, has not been processed by scientific methods and rules into a local oral tablet. objectives the purpose of this study was to investigate and compare the mechanical properties of qsmb with different size fractions of the mucilage powder, dried by oven or by freeze drying, to achieve...
The Percus-Yevick theory for monodisperse hard spheres gives very good results for the pressure and structure factor of the system in a whole range of densities that lie within the gas and liquid phases. However, the equation seems to lead to a very unacceptable result beyond that region. Namely, the Percus-Yevick theory predicts a smooth behavior of the pressure that diverges only when the vol...
هدف: این مطالعه به منظور مقایسه میزان اثربخشی سوچور سپتوم بینی و packing در بیماران تحت سپتوپلاستی در مراکز جراحی تخصصی شهر تهران و بیمارستان بوعلی طی سال های 89-88 انجام شده است. روش مطالعه: 146 فرد تحت سپتوپلاستی در این مطالعه مورد بررسی قرار گرفتند که به طور تصادفی ساده یک گروه 73 نفره nasal packing از نوع اسپلینت دریافت نمودند و یک گروه 73 نفره بدون nasal packing همراه با سوچور سپتوم بینی ...
This paper addresses the geometric random packing and void fraction of polydisperse particles. It is demonstrated that the bimodal packing can be transformed into a continuous particle-size distribution of the power law type. It follows that a maximum packing fraction of particles is obtained when the exponent (distribution modulus) of the power law function is zero, which is to say, the cumula...
The random sequential adsorption of various particle shapes is studied in order to determine the influence of particle anisotropy on the saturated random packing. For all tested particles there is an optimal level of anisotropy which maximizes the saturated packing fraction. It is found that a concave shape derived from a dimer of disks gives a packing fraction of 0.5833, which is comparable to...
Structures for the ramdam distributions of disks in one dimension are used ta calculate trie packing density of two dimensional random heaps of disks. Trie calculated values are compared with those obtained from computer simulations. Studies bave been done on trie random
Random dense packing of poly-disperse discs and spheres generated under the infinitesimal gravity protocol is investigated by a Monte Carlo simulation. For the binary discs packed in two dimensions, the packing fraction of disc assembly becomes lower than that of the monodisperse system when the size ratio is close to unity. We show that the suppressed packing fraction is caused by an increase ...
This paper addresses the packing and void fraction of polydisperse particles with a lognormal size distribution. It is demonstrated that a binomial particle size distribution can be transformed into a continuous particle-size distribution of the lognormal type. Furthermore, an original and exact expression is derived that predicts the packing fraction of mixtures of particles with a lognormal d...
