translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
background: despite demonstration of molecular and biochemical changes induced by heat shock on leishmania , the immunological importance of such changes has not been elucidated. objective: studying the effect of two excretory factors prepared under heat shock and ambient temperature from leishmania major on balb/c splenocytes function. methods: the parasites were cultured at 25 ° c and the...
objective neuromuscular characteristics in down syndrome result in generalized muscular hypotonia, developmental delays and sensory integration deficits. the aim of this study was to compare the effects of simultaneous sensory stimulations and current occupational therapy approaches on motor functions development of infants with down syndrome. materials & methods eighteen infants with down synd...
Marchenko methods are based on integral representations which express Green's functions for virtual sources and/or receivers in the subsurface terms of reflection response at surface. An underlying assumption is that inside medium wave field can be decomposed into downgoing and upgoing waves evanescent neglected. We present a new derivation function circumvents these assumptions, both acoustic ...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
Sliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency
In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...
The effect of an addition of 0.37 Wt % Won the overall transformation rate of the austenitepearlite reaction in a eutectoid steel is examined. Pearlite growth rates and interlamerllar spacing are measured as a function of transformation temperatures. Tungesten raises the Ael temperature, for most transformation temperatures, decreases the overall reaction rate, the growth rate and the interlame...
the mir-383-ldha axis regulates cell proliferation, invasion and glycolysis in hepatocellular cancer
objective(s): to explore the correlation between expression patterns and functions of mir-383 and ldha in hepatocellular cancer (hcc). materials and methods: we detected the expression of mir-383 and ldha in 30 hcc tissues and their matched adjacent normal tissues using qrt-pcr. then we performed mtt assay, foci formation assay, transwell migration assay, glucose uptake assay and lactate produc...
