Abstract. We introduce deformation theoretic methods for determining when a curve X in a nonhyperelliptic Jacobian JC will deform with JC to a non-Jacobian. We apply these methods to a particular class of curves in the second symmetric power C of C. More precisely, given a pencil g1 d of degree d on C, let X be the curve parametrizing pairs of points in divisors of g1 d (see the paper for the p...

In the remainder, we call such a variety a convex symplectic variety. A convex symplectic variety has been studied in [K-V], [Ka 1] and [G-K]. One of main difficulties we meet is the fact that tangent objects TX and T 1 Y are not finite dimensional, since Y may possibly have non-isolated singularities; hence the usual deformation theory does not work well. Instead, in [K-V], [G-K], they introdu...

BACKGROUND BK virus nephropathy (BKVN) is one of the complications of renal transplantation that causes graft loss in renal transplant recipients. OBJECTIVE To determine the incidence of BKVN after renal transplantation in Hasheminejad Hospital, Tehran, Iran. METHODS In this analytical cross-sectional study, we evaluated 31 consecutive kidney transplant recipients (21 men and 10 women) for ...

Glioblastoma multiforme (GBM) is the most aggressive of the gliomas, a collection of tumors arising from glia in the central nervous system. Possible associations between the human cytomegalovirus (HCMV) and the JC virus with GBM are now attracting interest. Our present aim was to investigate the prevalence of the two viruses in Iranian patients from Kerman’s cities in the south of Iran. In add...

Many second phase additions to YBa₂Cu₃O7-x (YBCO) films, in particular those that self-assemble into aligned nanorod and nanoparticle structures, enhance performance in self and applied fields. Of particular interest for additions are Ba-containing perovskites that are compatible with YBCO. In this report, we discuss the addition of Ba₂YRuO₆ to bulk and thick-film YBCO. Sub-micron, randomly ori...

Previously explored combination therapies mostly involved the use of bioactive molecules. It is believed that herbal compounds containing multiple plant products have synergistic hepatoprotective effects and could enhance the desired actions. To investigate the combination of ethanolic fruits extract of Solanum xanthocarpum (SX) and Juniperus communis (JC) against Paracetamol (PCM) and Azithrom...

A new modified Johnson-Cook model is developed to capture the non-linear thermal softening behaviour below austenite transformation temperature (723°C) in C45 ferritic-pearlitic steel, which not captured by original (JC) model. The physical mechanisms responsible for this are also studied. experimental quasi-static and high strain rate axisymmetric compression testing from 20°C 720°C implemente...
