this paper aims at investigating evidentiality in contemporary persian from a typological point of view. first the category of evidentiality and its types in the languages of the world is introduced. gathering and analysing data of spoken and written form of this language as well as classic texts,  an attempt was made to see whether evidentiality exists in this language as a grammatical categor...

Calcium (Ca⁺²) is a ubiquitous messenger in eukaryotes including Caenorhabditis. Ca⁺²-mediated signalling processes are usually carried out through well characterized proteins like calmodulin (CaM) and other Ca⁺² binding proteins (CaBP). These proteins interact with different targets and activate it by bringing conformational changes. Majority of the EF-hand proteins in Caenorhabditis contain C...

In this paper, we are interested in the study of right polycyclic codes as invariant subspaces Fnq by a fixed operator TR. This approach has helped one hand to connect them ideals polynomials ring Fq [x]/?f)X)?, where f (x) is minimal polynomial On other hand, it allows prove that dual code adjoint Hence, when TR normal also code. However, isn?t equivalent Finally, cyclic case, BCH-like and Har...

background and purpose: hand contamination is an important factor of infection transmission from dental staff to patients and vice versa. the aim of this study was to determine the effect of hand washing training on dental students’ knowledge, attitude, and clinical practice at the shahid beheshti university of medical sciences dental school in 2010. methods: this quasi-experimental study was c...

Traditional hand geometry-based systems use low-resolution cameras or scanners to capture users’ hand images with the help of peggies or by forcing them to touch a screen. Those systems measure a hand shape to extract its features, like lengths and widths of fingers, and hand contour, for recognition. Unfortunately, traditional techniques face unsolved problems: low discriminability due to low-...
