sahand volcanic-sub-volcanic dome, along with several other magmatic domes in northwest iran and the southern part of tabriz fault show adakitic geochemical characteristics. sahand dome has mainly dacitic composition. the sio2 content and mg number of sahand dome range from 64 to 73 wt% and 27 to 57 respectively. sahand dome can be classified as high silica adakitic (hsa) type. the rocks studie...

in this paper, first the properties of one and two-dimensional differential transforms are presented.next, by using the idea of differential transform, we will present a method to find an approximate solution fora volterra integro-partial differential equations. this method can be easily applied to many linear andnonlinear problems and is capable of reducing computational works. in some particu...

results the results revealed that metal urine concentration in welders was higher than controls but only the difference in chromium concentration was significant (p < 0.002). in the range of metals exposure, induction of oxidative stress for exposed group was observed by increase in urine mda (11.17 ± 4.23 and 4.83 ± 1.82 mm in welders and controls, respectively; p < 0.01). information of the m...

Background and objectives: Anal fissure is a painful wound in the anoderm and distal to dentate line, the chronic fissure leads to hypertrophy and fibrosis. In this study, we compared partial and total sphincterotomy in patients with chronic anal fissure. Methods: In this comparative cohort, 100 patients (52 female and 48 male )mean age 43.34 ± 15.28 year...

recurrent sigmoid volvulus is a clinical entity characterized by recurrent episodes of partial or complete sigmoid volvulus. although it is commonly seen in the elderly, it can be occasionally seen in younger patients. patients with recurrent partial sigmoid volvulus are relatively asymptomatic or present with mild abdominal pain. early diagnosis and treatment is essential to prevent conversion...

This paper reveals some relations between fuzzy logic and quantum on partial residuated implications (PRIs) induced by t-norms as well proposes monoids (PRMs) lattices (PRLs) defining adjoint pairs. First of all, we introduce the connection lattice effect algebra according to concept given Borzooei, together with proof that operation in any commutative quasiresiduated is t-norm. Then, offer gen...

objective: the aim of the present study was to retrospectively evaluate small-diameter (3.3 mm) straumann® dental implants placed in the maxilla or the mandible over a period of 5 years in function. materials and methods: twenty- eight partially edentulous patients received a total of 48 implants over a 5-year period. after the standard healing period (3 to 6 months), the implants were restored...

in this paper, we investigate the zassenhaus conjecture for $psl(4,3)$ and $psl(5,2)$. consequently, we prove that the prime graph question is true for both groups.
