In the present paper, an experimental assessment was performed on the transient thermal performance of a heat sink filled by a phase change material (PCM) and PCM embedded with carbon nanofibers (CNFs) and titania (TiO2) nanoparticles as nanostructured materials. In order to enhance the thermal conductivity of PCM, CNFs and TiO2 nanoparticles at different loadings (0.5wt. % and 2 wt.% of CNFs a...
Background and Objective: Poly D,L-lactic-co-glycolic acid (PLGA) is known as biodegradable and biocompatible polymer. These polymers have recently received much attention in tissue engineering. The aim of this study was to investigate the biological behavior of the bone marrow stromal cells (BMSCs) in culturing with PLGA nanofibers coated with poly-L-lysine or gelatin. Materials and Methods: I...
abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...
The paper presents equivalent substitution circuits (ESCs) describing nanogranular composite films (Fe0.45Cо0.45Zr0.10)x(Al2O3)1 – x and (Fe0.45Cо0.45Zr0.10)x(PZT)1 with a concentration of metal-containing granules in the range 0.3 < х 0.8. Films 2–7 μm thick were obtained by ion-beam sputtering targets pure argon or Ar O2 mixture, followed stepwise (with step 25 K) isochronous (15 min) anne...
an investigation into oral interaction in language classes: a conversation analytic point of view the aim of this thesis is to analyze the interaction between language teachers and students in english language institutes. this work is done in the context of yasuj city. learning another language, which is in most cases english, involves many variables. one of these variables is the linguistic...
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
Shock compression experiments achieving ≥100 GPa pressures are available for seven silicate liquid compositions in the system CaO-MgO-FeO-Al2O3-SiO2. Especially when liquid states have been sampled along multiple Hugoniots, these data are sufficient to evaluate the dependence of Grüneisen γ on volume in silicate liquids. The increase in γ upon compression in these liquids is a surprising featur...
Introduction: Knowledge of the surface mineralogy and chemistry of the crust is central to understanding the evolution of the lunar crust. Using the 5-band ultravioletvisible (UVVIS) Clementine data set, Tompkins and Pieters [1] showed that approximate mineralogy could be determined from Clementine data and analyzed 109 impact craters detailing the approximate mineralogy, or rocktypes, of their...
Background and Objectives: Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of nosocomial and community acquired infections. Detection of MRSA in laboratories is very important for treatment and appropriate infection control. The aim of this study was to evaluate cefoxitin disk diffusi...
The binding behavior of nanoaggregates of pentacenequinone derivative 1 having thiophene groups has been investigated toward various cations (Fe(3+), Fe(2+), Pd(2+), Mg(2+), Cd(2+), Hg(2+), Ni(2+), Zn(2+), Cu(2+), Pb(2+), Co(2+), K(+), Na(+) and Li(+)) using UV-vis and fluorescence spectroscopy. Among the various cations tested, nanoaggregates of compound 1 show a selective and sensitive respon...
