This paper presents an analysis of technical efficiency and technology gap ratio (TGR) in greenhouse cucumber in Fars Province, Iran. Cucumber production was chosen for this study for the reason that greenhouse productions in this provincemainly have focused on this product. The data used in this study was obtained from a random sample of 127 greenhouses in Fars Province for 2010 to 2011. Metaf...

Cobalt (Co) doped Zinc Oxide (ZnO) thin films, containing different amountof Cobalt nanoparticles as the Co doping source, deposited by the sol–gel spin coatingmethod onto glass via annealing temperature at 400˚C, have been investigated by opticalcharacterization method. The effect of Co incorporation on the surface morphology wasclearly observed from scanning electron microscopy (SEM) images. ...

We examine the validity of the zero duality gap properties for two important dual schemes: a generalized augmented Lagrangian dual scheme and a nonlinear Lagrangetype dual scheme. The necessary and sufficient conditions for the zero duality gap property to hold are established in terms of the lower semicontinuity of the perturbation functions.

We study maximal monotone inclusions from the perspective of (convex) gap functions. We propose a very natural gap function and will demonstrate how this function arises from the Fitzpatrick function — a convex function used effectively to represent maximal monotone operators. • This approach allows us to use the powerful strong Fitzpatrick inequality to analyse solutions of the inclusion. – We...

We tested the hypothesis that focally perfusing carbenoxolone, which blocks gap junctions, into the nucleus tractus solitarius (NTS) would reduce the ventilatory response to CO(2). We measured minute ventilation (V(E)), tidal volume (V(T)) and respiratory frequency (F(R)) responses to increasing concentrations of inspired CO(2) (F(I)(CO(2) = 0-8%) in rats during wakefulness. Focal perfusion of ...

Partial recursive functions which equal the amount of time or space required by computations have special properties which distinguish them from arbitrary partial recursive functions. Our main result illustrates a property of running times similar in interpretation to Borodin's gap theorem. The proof is based on the construction of difficult to compute characteristic functions which take the va...

To consider the origin of a pseudo-gap and a superconducting gap found in the high-Tc cuprates, the momentum dependence of the singlet gap parameter and the superconductivity correlation function are evaluated in the t–J model by using an optimization variational Monte Carlo method. In the underdoped regime, the singlet gap is significantly modified from the simple dx2−y2-wave gap (∝ cos kx − c...

In this work the procedure to the synthesis of Ba2GdSbO6 complex perovskite by the solid-state reaction method is reported. Theoretically a study of the crystalline and electronic structure was performed into the framework of the Density Functional Theory (DFT). The most stable structure is obtained to be a rhombohedral perovskite with a lattice constant a=6,0840 Å.  Due the occurren...

In previous mathematical studies of the BCS gap equation of superconductivity, the gap function was regarded as an element of a space consisting of functions of the wave vector only. But we regard it as an element of a Banach space consisting of functions both of the temperature and of the wave vector. On the basis of the implicit function theorem we first show that there is a unique solution o...

Let F be an algebraic function field in one variable defined over an algebraically closed field K of characteristic p ≥ 0. For any given place P of F , a number s is called a non-gap at P if there exists a function z ∈ F such that the pole divisor of z is (z)∞ = sP . If there is no such function, the number s is called a gap at P . If g is the genus of F , it follows from the Riemann-Roch theor...
