In this paper, we present a general scheme to produce interactive and static orthogonal drawings of graphs. As opposed to most known algorithms, we do not restrict ourselves to graph with maximum degree 4, but allow arbitrary degrees. We show here how, with one speciic implementation of the scheme, we can obtain an m+n 2 m+n 2-grid for all simple connected graphs without nodes of degree 1. Furt...
Background: Fear of dental care prevents dental cleaning behavior and increases the prevalence of dental caries. This study was conducted to determine the effect of Trans-Theoretical Model constructs and fear of dental care on the dental cleaning behavior of students. <span style="font-family...
مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...
Introduction: Biliary tract injury is a major complication of laparoscopic cholecystectomywhich can be very challenging. But, the important part is to know the accurate anatomy of the ducts and site of the injury before any surgical attempt for ligation or repair. In this case a disaster might happ...
عامل های فرآیندی بسیاری بر چگونگی عملکرد نانوفیبر سلولز به عنوان یک تقویت‌کنندۀ سلولزی دوست‌دار محیط زیست تأثیرگذارند. یکی از عامل های بالقوه تأثیرگذار، دمای اختلاط سوسپانسیون خمیر با نانوفیبر سلولز بوده که در این تحقیق به آن پرداخته شده است. به منظور بررسی تأثیر این مشخصه شتاب آبگیری اختلاط به دست آمده و ویژگی های مقاومتی کاغذ نهایی تولیدشده مورد آزمون و بررسی ...
Background: Green tea polyphenols (GTP) are known to have several health benefits. In spite of these benefits, its application as a therapeutic agent is limited due to some of its limitations such as stability, bioavailability, and biotransformation. To overcome these limitations, liposomal nanoparticles have been used as a carrier of the GTP. <spa...
The perovskite-type oxides strontium-substituted lanthanum nickelate (LSNO) were prepared by a coprecipitation method in the present of octanoic acid as surfactant. The phase composition, morphology,lattice parameters and size of nanoparticles in these materials were characterized through Fourier transform infr...
Methods for small area estimation have been received great attention in recent years due to growing demand for reliable small area estimation that are needed in development planings, allocation of government funds and marking business decisions. The key question in small area estimation is how to obtain reliable estimations when sample size is small. When only a few observations(or even no o...
background: estimating dosimetric parameters for small fields under non-reference conditions leads to significant errors if done based on conventional protocols used for large fields in reference conditions. hence, further correction factors have been introduced to take into account the influence of spectral quality changes when various detectors are used in non-reference conditions at differen...
