Introduction: Thesinonasal tract is an area that may be affected by various types of neoplastic lesions with more variety than what is encountered in other parts of the upper airway and food passage.   Case Report: An elderly gentleman of 65 years complained of nose block on both sides for 3 months. On examination, he had firm polypoidal masses arising from the middle me...

A fast and simple modified QuEChERS extraction method was developed for determination of Benzo[a]pyrene (BaP) in 137 traditional (Sangak), semi-industrial (Sangak) and industrial bread samples using spiked calibration curves by GC/MS. Sample preparation includes extraction of BaP into acetone followed by cleanup with dispersive solid phase extraction. The limit of detection and limit of quantif...

the mode of heat and mass transfer during baking of bakery products is an important factor determining the quality of the final product. the heating rate could alter the starch properties during gelatinization and affect the quality of products after baking and during aging. sangak is a kind of iranian flat bread baked on the hot pebble gravels. the aim of this study was to evaluate the impacts...

background: consistency, backing process and content differences could influence cariogenic potential of foods. the aim was to compare plaque ph changes following consumption of two types of bread with different physical characteristics. methods: in this clinical trial, interproximal plaque ph of 10 volunteers with high risk of dental caries (saliva streptococcus mutans > 10 5 , high dental car...

Symbol-pair codes, introduced by Cassuto and Blaum [1], have been raised for symbol-pair read channels. This new idea is motivated by the limitations of the reading process in high-density data storage technologies. Yaakobi et al. [8] introduced codes for b-symbol read channels, where the read operation is performed as a consecutive sequence of b > 2 symbols. In this paper, we come up with a me...

Recently, Yaakobi et al. introduced codes for b-symbol read channels, where the read operation is performed as a consecutive sequence of b > 2 symbols. In this paper, we establish a Singleton-type bound on b-symbol codes. Codes meeting the Singleton-type bound are called maximum distance separable (MDS) codes, and they are optimal in the sense they attain the maximal minimum bdistance. Based on...

Consider a system of asynchronous processes that communicate among themselves by only executing read and write operations on a set of shared variables (also known as shared registers). The system has no global clock or other synchronization primitives. Every shared variable is associated with a process (called owner) which writes it and the other processes may read it. An execution of a write (...
