اثر زمان انباشت در تغییر ساختار نانوذرات نقره ساخته شده در بستری از کربن شبهالماسی به روش RF-PECVD
Silver nanoparticles embedded in DLC matrix, were prepared by co-deposition of RF-Sputtering and RF-PECVD method from acetylene gas and sliver target. The RF power and initial pressure of chamber were fixed. Variations of morphology, optical and electrical properties of these films over time were investigated
The scenario of multi-sector SUSY breaking predicts pseudo-goldstinos which are not absorbed by the gravitino and their mass can be as low ${{\cal O} (0.1)}$ GeV. Since interactions so weak gravitino, a produced higgsino decay to pseudo-goldstino plus Higgs boson insider detector at LHC, thus pair production lead signal missing energy. For natural requires rather light higgsinos, such events ma...
Introduction & Objective: Acute promyelocytic leukemia (APL) is a kind of acute leukemia characterized by a balanced t (15, 17) translocation which fails to develop into mature cells and proliferate in an unregulated fashion. In the recent years, in addition to combinatoral chemotherapy to treat unmature cancerous cells, differentiation therapy by differentiating agents as a novel procedure ...
Background and aims: Health literacy (HL) can affect individual health, health communication anderror in taking medicine. The aim of this study was to determine the level of HL and associated factorsamong Iranian adults.Methods: In this cross-sectional study, 240 participants over 18 years of age referring to health centersin Hamadan, west of Iran in 2015 were selected b...
The HL-60 leukemia cell line derived from a human acute promyelocytic leukemia is stimulated to differentiate into macrophages within 24-28 hr after exposure to the phorbol ester, 12-O-tetradecanoylphorbol-13-acetate (TPA). We studied early alterations (within 90 min of exposure to TPA) in phosphatidylcholine metabolism in HL-60 cells and found that phosphatidylcholine synthesis by methylation ...
Biometrics is a technology that has been widely used in many official and commercial identification applications. The extracted features from the biometric sample is called biometric template which is used during a biometric authentication process. The security of templates is the critical part of biometric system and one of the most crucial issues in designing a secure system. The proposed app...
INTRODUCTION Radiofrequency (RF) pulse angle inhomogeneity is a significant problem in breast MRI at 3T. Dynamic contrast-enhanced (DCE)-MRI of the breast with FLASH is susceptible to this RF inhomogeneity, and results in errors in the measurement of tumour enhancement ratio (ER) [1], where ER is a function of changes in relaxation rate (ΔR1) and represents contrast agent concentration in the t...
Retinoic acid is known to cause the cell cycle arrest and myeloid differentiation of HL-60 myeloblastic leukemia cells. Evidence suggesting the possible involvement of the Fc RII immunoglobulin receptor in mediating retinoic acid-induced growth arrest and differentiation of HL-60 cells is presented. HL-60 cells stably transfected with the 205 mutant polyoma middle T antigen, a largely debilitat...
A review of radio frequency microelectromechanical systems (RF MEMS) technology, from the perspective of its enabling technologies (e.g. fabrication, RF micromachined components and actuation mechanisms) is presented. A unique roadmap is given that shows how enabling technologies, RF MEMS components, RF MEMS circuits and RF microsystems packaging are linked together; leading towards enhanced in...
Background: Rheumatoid factor (RF) is an IgM antibody against the Fc portion of IgG, which together form an immune complex. RF is an important criterion in the diagnosis of early-stage rheumatoid arthritis (RA) and prognosis of RA pathogenesis, as higher levels of RF indicate a higher possibility of more damage. Although 2/3 to 3/4 of patients that undergo ordinary standard tests and have final...
