a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Geometrical tests such as the combination of the Hubble parameter H(z) and the angular diameter distance dA(z) can, in principle, break the degeneracy between the dark energy equation of state parameter w(z), and the spatial curvature Ωk in a direct, model-independent way. In practice, constraints on these quantities achievable from realistic experiments, such as those to be provided by Baryon ...
We present a new approach for the fast visualization and evaluation of large point clouds derived from different structured light 3D-scanners. By using the underlying measuring principle, we generate regular quadrilateral meshes in nearly real-time. These meshes are additionally used for a partial NURBS approximation. Based on the derived parameterized surfaces we are able to calculate and meas...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
as the canon is shaped by white male standards rewriting the canonical works of literature is one of the ways through which postcolonial writers subvert the authority of the masters. writing in the language of the masters the colonized writers use the very suppressive tool in the hands of the masters i.e. their language to question the validity of their norms. regarded by most critics to be the...
Assuming axial symmetry, we introduce a surface of revolution approach to model the membrane at equilibrium. We consider a generating curve γ parameterized by arc length s lying in the x− z plane. The curve γ is expressed as γ(0, s1) → R γ(s) = (R(s), 0, z(s)) (S1.1) where s1 is the total arc-length. This generating curve leads to a global parametrization of the membrane expressed as X : (0, s1...
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
The propagation characteristics of a scalar Gaussian beam in a homogeneous anisotropic medium are considered. The medium is described by a generic wave-number profile wherein the field is formulated by a Gaussian plane-wave distribution and the propagation is obtained by saddle-point asymptotics to extract the Gaussian beam phenomenology in the anisotropic environment. The resultant field is pa...
In this paper, the problem of delay dependent robust asymptotically stable for uncertain linear time-variant system with multiple delays is investigated. A new delay-dependent stability sufficient condition is given by using the Lyapunov method, linear matrix inequality (LMI), parameterized first-order model transformation technique and transformation of the interval uncertainty in to the norm ...
