Telaranea europaea (Lepidoziaceae, Hepaticae), new for Turkey
(Adac-Cryptogamie, 2007)
Telaranea europaea (Lepidoziaceae, Hepaticae) is reported for the first time in Turkey, based on specimens collected in Kiyicik Village (Rize, Turkey). This is also the first record of the genus Telaranea in Turkey and ...
Bleimann, Butzer, and Hahn Operators Based on the q-Integers
(Hindawi Publishing Corporation, 2007)
We give a new generalization of Bleimann, Butzer, and Hahn operators, which includes q-integers. We investigate uniform approximation of these new operators on some subspace of bounded and continuous functions. In Section ...
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), ...
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 ...
