Punica granatum (Pg), commonly known as pomegranate (Pg), is a member of the monogeneric family, Punicaceae, and is mainly found in Iran which is considered to be its primary centre of origin. Pg and its chemical components possess various pharmacological and toxicological properties including antioxidant, anti-inflammatory (by inhibiting pro-inflammatory cytokines), anti-cancer and anti-angiog...

We find all minimal blocking sets of size 32 ðpþ 1Þ in PGð2; pÞ for p < 41. There is one new sporadic example, for p 1⁄4 13. We find all maximal partial spreads of size 45 in PGð3; 7Þ. 1 Minimal nontrivial blocking sets in PG(2, p) A blocking set in a projective plane is a set of points meeting all lines. It is called nontrivial when it does not contain a line. An m-secant of a set is a line me...

Let V be a 2m-dimensional vector space over a field F (m ≥ 2) and let k ∈ {1, . . . , 2m − 1}. Let A2m−1,k denote the Grassmannian of the (k − 1)-dimensional subspaces of PG(V ) and let egr denote the Grassmann embedding of A2m−1,k into PG( ∧k V ). Let S be a regular spread of PG(V ) and let XS denote the set of all (k − 1)-dimensional subspaces of PG(V ) which contain at least one line of S. T...

در این پژوهش، اثر جوشکاری اصطکاکی-اغتشاشی بر مقاومت به خوردگی فولاد زنگ‌نزن دوفازی کم‌آلیاژ بررسی شده است. برای این منظور، آلیاژ مذکور در سرعت چرخشی rpm 800 و سرعت پیشروی mm/min 150 جوشکاری شد. ریزساختار نمونه‌های فلز پایه و جوش با استفاده از پراش پرتو ایکس (XRD) و میکروسکوپ الکترونی روبشی (SEM) مورد مطالعه قرار گرفت. رفتار خوردگی این نمونه‌ها با استفاده از آزمون‌های      اندازه‌گیری پتانسیل مد...

In this paper, we introduce $(p,q)g-$Bessel multipliers in Banach spaces and we show that under some conditions a $(p,q)g-$Bessel multiplier is invertible. Also, we show the continuous dependency of $(p,q)g-$Bessel multipliers on their parameters.

This study aimed to improve delivery of lomustine as a chemotherapeutic agent and to increase its uptake by U87-MG cancer cells via synthesizes LN-FA-PG-SPIONs (lomustine loaded polyglycerol coated superparamagnetic iron oxide nanoparticles conjugated with folic acid). Nanoparticles were synthesized by thermal decomposition method and characterized using TEM (transmission microscope), FTIR (Fou...

Let and B̄ be a subset of = PG(2n − 1, q) and a subset of PG(2n, q) respectively, with ⊂ PG(2n, q) and B̄ ⊂ . Denote by K the cone of vertex and base B̄ and consider the point set B defined by B = (K\ ) ∪ {X ∈ S : X ∩ K = ∅}, in the André, Bruck-Bose representation of PG(2, qn) in PG(2n, q) associated to a regular spread S of PG(2n − 1, q). We are interested in finding conditions on B̄ and in order...

A full classification (up to equivalence) of all complete k-arcs in the Desarguesian projective planes of order 27 and 29 was obtained by computer. The resulting numbers of complete arcs are tabulated according to size of the arc and type of the automorphism group, and also according to the type of algebraic curve into which they can be embedded. For the arcs with the larger automorphism groups...

Two high galactic latitude B-type stars, PG 1323−086 and PG 1704+222, are analysed from low and medium resolution optical spectra and Strömgren photometry. A differential abundance analysis for He, C, N, O, Mg, Al, and Si reveals that the He abundance is close to solar while metal underabundances relative to the solar value of typically 1.3 and 1.2 dex for PG 1323−086 and PG 1704+222, respectiv...
