A bstract The $$ T\overline{T} T ¯ deformation can be formulated as a dynamical change of coordinates. We establish and generalize this relation to curved spaces by coupling the undeformed theory 2d gravity. For space coordinates is supplemented Weyl transformation. a...
امروزه ساخت و مطالعه نانوکامپوزیتهای زمینه آلومینیم با مقاومساز نانوتیوب کربن مورد توجه بسیاری از پژوهشگران قرار گرفته است. روشهای مختلفی برای فرآوری این نوع نانوکامپوزیتها استفاده شده است. اما، روشهای بر پایه متالورژی پودر با توجه به پایینتر بودن دما و کنترل بهتر فرآیند، بیشتر مورد توجه بوده است. در تحقیق حاضر با هدف ساخت نانوکامپوزیت با زمینه آلومینیم 2024 و افزودن CNT wt.% 5/1، از روش ...
sarcoidosis is a systemic granulomatous disorder of unidentified etiology, with a heterogeneous clinical presentation. it is characterized by a reduced delayed-type hypersensitivity to tuberculin and common antigens. the balance between th1, th17 and regulatory t(treg) cells controls t-cell proliferation and activation.the th17/treg ratio in the peripheral blood and bronchoalveolar lavage fluid...
Introduction: IL-8 is one of the pro-inflammatory cytokines which can play an essential role in the pathogenesis of chronic rhinosinusitis (CRS) as well as nasal polyposis (NP). The ability of individuals in producing IL-8 is partially determined by IL-8-251 A/T polymorphism. Hence, the aim of the present study was to investigate the association between IL-8-251 A/T and CXCR2 +1208 C/T genes ...
Background and Objective: Asthma is a common respiratory disease caused by acute and chronic bronchial inflammation. Clinical manifestations of the disease are closely related to genetics. IL-4 is a cytokine of TH2 lymphocytes, polymorphism in prompter region, C-589T, is associated with IL-4 production, while IFN-γ, is a cytokine of TH1, and A+874T polymorphism in interon 1 of IFN-γ is associat...
Let $T$ be a non-trivial tournament. An arc is emph{$t$-pancyclic} in $T$, if it is contained in a cycle of length $ell$ for every $tleq ell leq |V(T)|$. Let $p^t(T)$ denote the number of $t$-pancyclic arcs in $T$ and $h^t(T)$ the maximum number of $t$-pancyclic arcs contained in the same Hamiltonian cycle of $T$. Moon ({em J. Combin. Inform. System Sci.}, {bf 19} (1994), 207-214) showed that $...
A bstract We generate a class of string backgrounds by sequence TsT transformations the NS1-NS5 system that we argue are holographically dual to states in single-trace $$ T\overline{T} T ¯ + J\overline{T} J T\overline{J} -deformed CFT 2 . The new incl...
