Research ArticleOpen accessIn the abstractPetrology, Geochemistry and Magnetization of Remah Volcano North Eastern JordanMazen AL-AmairehPeridotite ultramafic mantle xenoliths are occurring abundantly in the Harrat Al-Shaam basaltic province. Jabal Remah volcano is located in the Jordanian parts of the plateau and contains considerable amounts of mantle xenoliths within its pyroclastic successions. Mineralogical investigations show that the xenoliths are mostly of the spinel Iherzolite type, which are characterized by a protogranular texture. Modally, the xenoliths are … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroduction of Three Complementary Technologies into Clinical Medicine: Development of New Diagnostic and Prognostic ParametersGernot P. Tilz, Marco Wiltgen, Ulrike Demel et al.Molecular medicine leads us to understand some diseases at the molecular level. Examples are the analysis of immune complexes and receptor - anti receptor compounds used in clinical medicine. Structural changes of some serum proteins occur in inflammation, neoplasie and autoimmunity. The detection and analysis of such structural modifications may offer a new field for the diagnosis, prognosis and therapy … …American Journal of Immunology, Vol. 2, Issue 1 · 31 Mar 2006 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractCyclic Volta Metric Study of Alizarin Yellow R and Some Analogous Arylazo Compounds in DMF and in Aqueous MediaHossnia MohranThe Cyclic Voltammetry (CV) was used to investigate the electrochemical behavior of alizarin yellow R and some analogous arylazo compounds having almost the same central azo group. For this purpose, the substances chosen for the measurements are Alizarin Yellow R (AYR), Eriochrome Black T (EBT) and Sudan II (SUD II). The investigations were carried out at room temperature (298 K) … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 7,235 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Application of Electrochemical Impedance Techniques in Analyzing the AC Response of Some Two-electron Transfer Dye SystemsFarouk RashwanThe Electrochemical Impedance Spectroscopic techniques (EIS) were used to investigate the behavior of some dye compounds (quinoid systems) characterized with 2e-transfer processes. For this purpose, Alizarin Red S (ARS), Alizarin Cyanine (AC), Alizarin Viridin (AV) and carminic acid were chosen for the measurements. The EIS experiments were performed using a small AC amplitude (10 mV p-p) in addition to a … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractFurther Improvements in Temperature Calculation During Cooling of Fish PackagesF. A. Ansari, K. A. Abbas, J. Bakar et al.In an earlier study, it was demonstrated that the empirical approach used to calculate the surface film conductance resulted into a higher value compared to those obtained from the other methods available in the literature. During further investigations, surface film conductance values were found to gradually decrease with a fall in temperature. When this non-linear variation was used to develop … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,848 accessesView PDFCite
