پرستاری رشته ای مبتنی بر عمل است. نقش عمده ای که کار در بالین در توسعه مهارت های پرستاری دارد، دانشجویان این رشته را ملزم می سازد که یاد بگیرند چگونه در محیط بالینی به عنوان فردی حرفه ای عمل کنند. مطالعات زیادی در زمینه محیط یادگیری بالینی دانشجویان پرستاری و مشکلات مربوط به آن انجام شده است، اما تجربه بالینی دانشجویان پرستاری کمتر به عنوان یک کل مورد توجه قرار گرفته است. روش مورد استفاده در ...
in this paper, a monotone positive solution is studied for buckling of a distributed model of multi walled carbon nanotube (mwcnt) cantilevers in the vicinity of thin and thick graphite sheets subject to intermolecular forces. in the modeling of intermolecular forces, van der waals forces are taken into account. a hybrid nano-scale continuum model based on lennard–jones potential is applied to ...
ellis van creveld یا دیس پلازی کندرواکتودرمال یک بیماری نادر با وراثت اتوزوم مغلوب است که شامل تتراد کندرودیس پلازی، دیس پلازی اکتودرمال، پلی داکتیلی و بیماری مادرزادی قلب است که معمولاً به صورت دهلیز منفرد تظاهر می کند. کندرودیس پلازی در استخوان های بلند، شایع ترین یافته بالینی است؛ در حالی که آنومالی های سیستم عصبی مرکزی و دستگاه ادراری از موارد نادر مرتبط با آن می باشد. گزارش مورد یک دختر با ...
A six year old child with symmetric polydactyly of both hands and genu valgum deformity was referred for radiographic assessment. On physical examination, there were six digits in both hands with dysplastic finger nails. The upper and lower extremies were shortened out of proportions to the trunk with genu valgum deformity. Radiograph of hands revealed bifid 5th metacarpals and complete duplica...
In this work it was developed a Van de Graaff generator that we design and built and that is intended to be used in secondary schools for teaching basic principles of electrostatics, electromagnetic as well as a number of other applications. Today many schools laboratories and museums use this kind of generator for electrostatic demonstrations. Electrostatics was first noticed by the Greek phil...
Many cognitive activities are irreducibly social, involving interaction between several different agents. We look at some examples of this in linguistic communication and games, and show how logical methods provide exact models for the relevant information flow and world change. Finally, we discuss possible connections in this arena between logico-computational approaches and experimental cogni...

Background: Postexercise muscle glycogen synthesis is an important factor in determining the time needed to recover from prolonged exercise. Objective: This study investigated whether an increase in carbohydrate intake, ingestion of a mixture of protein hydrolysate and amino acids in combination with carbohydrate, or both results in higher postexercise muscle glycogen synthesis rates than does ...
the one-dimensional model of lippincott and schroeder for hydrogen bond has been re-examined and it has been shown that o-h bond distance depends on repulsive van der waals and attractive electrostatic potentials.it has been shown that constant b in the van der waals repulsion potential is not transferable to all hydrogen bonds. the possibility of obtaining the semi-empircal parameters in the l...
