(Wiley-V C H Verlag Gmbh, 2004)
A glass-ceramic Bi1.7V0.3Sr2Ca2Cu3Ox superconductor was prepared by the melt-quenching method. The compound was characterized by scanning electron microscopy, x-ray diffraction, differential thermal analysis, current-voltage ...
A study for estimating solar resources in Turkey using artificial neural networks
(Taylor & Francis Inc, 2004)
Turkey has sufficient solar radiation and radiation period for solar thermal applications since it lies in a sunny belt between 36degrees and 42degreesN latitudes. The yearly average solar radiation is 3.6 kWh/m(2) day, ...
Color Doppler imaging in optic neuritis with multiple sclerosis
(Springer, 2004)
Purpose: To evaluate the retrobulbar hemodynamics in eyes with optic neuritis with multiple sclerosis and to compare these values with those of the unaffected fellow eyes and healthy control eyes. Methods: Thirty-four eyes ...
Permeation and separation characteristics of acetic acid/water mixtures through poly(vinyl alcohol-g-itaconic acid) membranes by pervaporation, evapomeation, and temperature-difference evapomeation
(Wiley, 2004)
In this study, itaconic acid (IA) was grafted onto poly(vinyl alcohol) (PVA) with cerium(IV) ammonium nitrate as an initiator at 45degreesC. The grafted PVA was characterized with Fourier transform infrared spectroscopy, ...
