Background: Paranasal sinus disease is one of the most common problems of patients that refer to ENT centers. Adding to clinical examination imaging plays an important role in diagnosis and treatment. Also the imaging of paranasal sinuses is necessary before surgery. Although computed tomography is the modality of choice for these areas, it has some disadvantages which the most important one is...

central granular cell odontogenic tumor) cgcot) of the jaw is an exceedingly rare benign odontogenic neoplasm with 35 reported cases in the literature. among these, very few studies have focused on the cone-beam ct features of cgcot. here, we report a case of an asymptomatic cgcot in a 16-year-old girl and focus on the cone-beam ct features. only 36 cases of this lesion, including this one, hav...

In this paper, some categorical properties of the category ${bf Cpo}_{{bf Act}text{-}S}$ of all {cpo $S$-acts}, cpo's equipped with actions of a monoid $S$ on them, and strict continuous action-preserving maps between them is considered. In particular, we describe products and coproducts in this category, and consider monomorphisms and epimorphisms. Also, we show that the forgetful functor from...

PURPOSE It has not been clarified whether early age-related macular degeneration (AMD) is associated with cone photoreceptor distribution. We used adaptive optics fundus camera to examine cone photoreceptors in the macular area of aged patients and quantitatively analyzed its relationship between the presence of early AMD and cone distribution. METHODS Sixty cases aged 50 or older were studie...

درک رنگ پاسخ قشر مغز در برابر محرک فیزیکی خاصی است که توسط شبکیه دریافت میشود. باند باریکی از طیف الکترومغناطیسی (طول موج 400-700nm) توسط رنگدانه های بینایی واقع در گیرنده های نوری سلولهای مخروطی (cone) قابل جذب است . این سلولها مخروطی 3 گیرنده آبی، سبز، و قرمز هستند و دید رنگ طبیعی نیاز به هر 3 رنگدانه دارد. نقایص دید رنگ بطور کلی به دو دسته اکتسابی و مادرزادی تقسیم می شوند که نقایص دید رنگ ما...

Let $X$ be a  Banach  space, $Csubset X$  be  a  closed  convex  set  included  in  a well-based cone $K$, and also let $sigma_C$ be the support function which is defined on $C$. In this note, we first study the existence of a  bounded base for the cone $K$, then using the obtained results, we find some geometric conditions for the set  $C$,  so that ${mathop{rm int}}(mathrm{dom} sigma_C) neqem...

Huang and Zhang cite{Huang} have introduced the concept of cone metric space where the set of real numbers is replaced by an ordered Banach space. Shojaei cite{shojaei} has obtained points of coincidence and common fixed points for s-Contraction mappings which satisfy generalized contractive type conditions in a complete cone metric space.In this paper, the notion of complete cone metric ...

We study the representation theory of increasing monoid. Our results provide a fairly comprehensive picture category: for example, we describe Grothendieck group (including effective cone), classify injective objects, establish properties and projective resolutions, construct derived auto-duality, so on. work is motivated by numerous connections this to other areas, such as stability, commutati...

Ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. A number of algorithms such as floating or moving cone method, floating cone method II and the corrected forms of this method, the Korobov algorithm and the corrected form of this method, dynamic programming and the Lerchs and Grossmann algorithm based on grap...
