A set C of vertices in a graph G = (V,E) is total dominating in G if all vertices of V are adjacent to a vertex of C. Furthermore, if a total dominating set C in G has the additional property that for any distinct vertices u, v ∈ V \ C the subsets formed by the vertices of C respectively adjacent to u and v are different, then we say that C is a locating-total dominating set in G. Previously, l...

Although chemotherapy is designed to eradicate tumor cells, it also has significant effects on normal tissues. The platinum-induced fatty acid 16:4(n-3) (hexadeca-4,7,10,13-tetraenoic acid) induces systemic resistance to a broad range of DNA-damaging chemotherapeutics. We show that 16:4(n-3) exerts its effect by activating splenic F4/80+/CD11blow macrophages, which results in production of chem...

Let (R,m) be a Noetherian local ring, M be a finitely generated R-module of dimension n and a be an ideal of R. In this paper, generalizing the main results of Dibaei and Jafari [3] and Rezaei [8], we will show that if T is a subset of AsshR M, then there exists an ideal a of R such that AttR Hna (M)=T. As an application, we give some relationships between top local cohomology modules and top f...

One of the important and basic topics in general topology and several branches of mathematics which have been researched by many authors is the continuity of functions. In this paper, we study (δ-pre, s)-continuous functions as a new weaker form of continuity. In 1996, Dontchev [3] introduced contra-continuous functions, and Jafari and Noiri [10] introduced contra-precontinuous functions (in 20...

according to previous studies, the genus rheum in iran includes four species: r. turkestanicum janisch., r. persicum losinsk., r. ribes l. and r. khorasanicum baradaran & jafari. during the long-term study, based on field and many herbaria specimens, three new species including r. iranshahrii taheri & assadi sp. nov., r. kordestanicum taheri & assadi sp. nov. and r. austro-iranicum taheri & ass...

Motivated by the importance of diffusion equations in many physical situations general and plasma physics particular, therefore, this study, we try to find some novel solutions fractional-order explain ambiguities about phenomena other fields. In article, implement two well-known analytical methods for solution equations. We suggest modified form homotopy perturbation method Adomian decompositi...

Breast cancer is one of the leading causes of death in women all over the world and its prevalence is increasing in many countries. It’s the most common cancer in Iranian women with a mortality rate of 2614 cases per year (Jafari et al., 2014; Sharifian et al., 2015). Early detection of that would be helpful for its successful treatment. Nowadays some techniques such as X-ray mammography, ultra...
