Gas Sensor Based on Large Hollow-Core Photonic Bandgap Fiber

One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...

On the Square Submodule of a Mixed Module

The notion of the square submodule of a module M over an arbitrary commutative ring R, which is denoted by RM, was introduced by Aghdam and Najafizadeh in [3]. In fact, RM is the R−submodule of M generated by the images of all bilinear maps on M. Furthermore, given a submodule N of an R−module M, we say that M is nil modulo N if μ(M×M) ≤ N for all bilinear maps μ on M. The main question about t...

Histological and Histochemical Study of Large and Small Intestine of Hydrophis cyanocinctus in Minab Beaches

The aim of the current study was to investigate the histological and histochemical characteristics of large and small intestines of sea snake, Hydrophis cyanocinctus. Six adult sea snakes were collected from Minab beaches, located near the sea of Oman, in November, euthanized with chloroform, dissected and alimentary canal removed, tissues preparaed for sectioning and staining with Hematoxylin ...

Relation between adenocarcinoma of stomach,bile ducts,small and large intestine with appendectomy

considering the structure of appendix,its great blood supply and lymphatic tissue,and its anatomical location it seems to have an immunologic role.there are no clear studies regarding the relation between appendectomy and cancer of digestive system.therefore,this stuty proposed for to clarify the relation between previous appendectomy and present gastrointestinal (GI)adenocarcinoma.the cancer g...
