In this paper, we establish a priori estimates for the three-dimensional compressible Euler equations with moving physical vacuum boundary, the γ-gas law equation of state for γ = 2 and the general initial density ρ0 ∈ H6(Ω). Because of the degeneracy of the initial density, we investigate the estimates of the horizontal spatial and time derivatives and then obtain the estimates of the normal o...
Background and purpose: Emergency medical services (EMS) are among the major concerns in health care. Documentation of patient care in medical records format is of great importance since they are used in further treatments, assessment of care, medical-legal reports, and medical educations. Materials and methods: This descriptive cross-sectional research was performed by studying the emergenc...
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
Yeast mutation accumulation experiment supports elevated mutation rates at highly transcribed sites.
Because mutation is the ultimate source of genetic variation, understanding mutational patterns and mechanisms is of fundamental importance. Previous studies provided geno-mic evidence that, in the bacteria Escherichia coli and Salmonella typhimurium, yeast Saccharomyces cerevisiae, and human germ line, the mutation rate of a gene generally increases with the expression level of the gene, likel...
طراحی و سنتز پلیمر های کئوردینانسیونی متخلخل یا چارچوب های فلز- آلی به علت ساختارهای جالب این ترکیبات و قابلیت های کاربردی آنها برای ذخیره و جداسازی گاز، کاتالیز، تشخیص و جداسازی انانتیومرها، خواص مغناطیسی، تنظیم لومینسانس و غیره توجه زیادی را به خود جلب کرده است. اخیرا مشخص شده است که برخی لیگاندهای آلی مسطح صلب مثل ایمیدازول-5،4-دی کربوکسیلیک اسید (h3idc) برای تشکیل چارچوب های فلز- آلی مناسب ...
