Comparative study of mathematical and experimental analysis of spark ignition engine performance used ethanol-gasoline blend fuel
(Pergamon-Elsevier Science Ltd, 2007)
This study consists of two cases: (i) The experimental analysis: Ethanol obtained from biomass can be used as a fuel in spark ignition engines. As renewable energy source ethanol, due to the high octane number, low emissions ...
Elucidating vegetation controls on the hydroclimatology of a mid-latitude basin
(Elsevier, 2007)
The rote of vegetation controls on the hydrological response to climatic variability of a mid-latitude watershed characterized by complex terrain and complex geology was assessed using a coupled surface-groundwater ...
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), ...
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 ...
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 ...
Chitosan-grafted poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) membranes for reversible enzyme immobilization
(Wiley, 2007)
Epoxy group-contain g poly(hydroxyethyl methacrylate/glycidyl methacrylate), p(HEMA/GMA), membrane was prepared by UV initiated photopolymerization. The membrane was grafted with chitosan (CH) and some of them were chelated ...
An adaptive control application in a large thermal combined power plant
(Pergamon-Elsevier Science Ltd, 2007)
In this paper, an adaptive controller was applied to a 765 MW large thermal power plant to decrease operating costs, increase quality of generated electricity and satisfy environmental concerns. Since power plants may ...

(Natl Med Assoc, 2007)
Objective: The objective of this study was to investigate the relationship between occupation and head and neck cancers. Patients and Methods: In this case-control study, 206 Turkish patients with head and neck cancers ...
Structure and Energetic of Bn (n = 2–12) Clusters: Electronic Structure Calculations
(Wiley, 2007)
The electronic and geometric structures, total and binding energies, first and second energy differences, harmonic frequencies, point symmetries, and highest occupied molecular orbital-lowest unoccupied molecular orbital ...
