Calculation for the thermodynamic properties of an alternative refrigerant (R508b) using artificial neural network
(Pergamon-Elsevier Science Ltd, 2007)
This study proposes a alternative approach based on artificial neural networks (ANNs) to determine the thermodynamic properties - specific volume, enthalpy and entropy - of an alternative refrigerant (R508b) for both ...
Release characteristics of diclofenac sodium from poly(vinyl alcohol)/sodium alginate and poly(vinyl alcohol)-grafted-poly(acrylamide)/sodium alginate blend beads
(Elsevier, 2007)
In this study, acrylamide (AAm) was grafted onto poly(vinyl alcohol) (PVA) with UV radiation at ambient temperature. The graft copolymer (PVA-g-PAAm) was characterized by using Fourier transform infrared spectroscopy (FTIR), ...
Preparation and characterization of sulfonyl-hydrazine attached poly(styrene-divinylbenzene) beads for separation of albumin
(Elsevier Science Bv, 2007)
Novel sulfonyl-hydrazine carrying poly(styrene-divinylbenzene), poly(S-DVB)-S-NH2 ion-exchange beads (size between 210 and 425 mu m) were prepared via suspension polymerization and, were first used as an ion-exchange support ...
Exergy analysis of an ejector-absorption heat transformer using artificial neural network approach
(Pergamon-Elsevier Science Ltd, 2007)
This paper proposes artificial neural networks (ANNs) technique as a new approach to determine the exergy losses of an ejector-absorption heat transformer (EAHT). Thermodynamic analysis of the EAHT is too complex due to ...
The role of sensory nerve conduction study of the palmar cutaneous nerve in the diagnosis of carpal tunnel syndrome in patients with polyneuropathy
(Neurol Soc India, 2007)
Background: Conventional methods in the diagnosis of carpal tunnel syndrome (CTS) in patients with polyneuropathy (PNP) are insufficient. Aims: We suggest that the comparison of the conduction of the median nerve with that ...
Reconstruction of mandibular defects using autografts combined with demineralized bone matrix and cancellous allograft
(Lippincott Williams & Wilkins, 2007)
Facial bone defects can be managed by a variety of means, such as inlay or onlay applied nonvascularized bone grafts, local pedicled/distal free osteocutaneous/osseous flaps or distraction osteogenesis. Although each method ...
A New Comparison of Empirical and Semi-empirical Formulae for the (n, 3He) Reaction Cross-sections at 14–15 MeV
(Springer, 2008)
New empirical and semi-empirical formulae have been suggested for the (n, He-3) reaction cross-sections with dependent on asymmetry parameter, S = (N - Z)/A. The (n, He-3) reaction cross-sections at the energy of 14-15 MeV ...
Calculation of 14-15 MeV (n, d) reaction cross sections using newly evaluated empirical and semi-empirical systematics
(Springer, 2008)
In this study, we have investigated the asymmetry term effect for the (n, d) reaction cross sections at 14-15 neutron incident energy. It has been discussed the odd-even effect and the pairing effect considering binding ...
q-generalizations of the Picard and Gauss-Weierstrass singular integrals
(Mathematical Soc Rep China, 2008)
Introducing a higher order modulus of smoothness based on q-integers, in this paper first we obtain Jackson-type estimates in approximation by Jackson-type generalizations of the q-Picard and q-Gauss-Weierstrass singular ...
Equilibrium and pre-equilibrium calculations of neutron production in medium-heavy targets irradiated by protons up to 100 MeV
(Pergamon-Elsevier Science Ltd, 2008)
In this study, by using equilibrium and pre-equilibrium reaction mechanisms, the (p,xn) cross-sections of the spallation neutron target nuclei Cr-50,Cr-52,Cr-53,Cr-54 and Cu-63,Cu-65 were investigated for incident proton ...
