in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
BACKGROUND White matter lesions in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) are underlaid by severe ultrastructural changes of the arteriolar wall. Although chronic ischemia is presumed to cause the tissue lesions, the pattern of perfusion abnormalities and hemodynamic reserve in CADASIL, particularly within the white matter, remains u...
In formal verification, we verify that a system is correct with respect to a specification. Cases like antecedent failure can make a successful pass of the verification procedure meaningless. Vacuity detection can signal such “meaningless” passes of the specification, and indeed vacuity checks are now a standard component in many commercial model checkers. We address two dimensions of vacuity: ...
The idea of fostering CAM in terms of an EU-funded project was influenced by SST’s research and EU project work in the field of occupational health. At the Viennese Academy of Integrative Medicine it was Wolfgang Marktl and Bettina Reiter who searched for potential international partners willing to support a CAM project at EU level. The first meeting for ‘CAM in FP 7’ (European Research Frame P...
There is evidence for a genetic component in caries susceptibility, and studies in humans have suggested that variation in enamel formation genes may contribute to caries. For the present study, we used DNA samples collected from 1,831 individuals from various population data sets. Single nucleotide polymorphism markers were genotyped in selected genes (ameloblastin, amelogenin, enamelin, tufte...
BACKGROUND The aim of this study was to establish the sputum inflammatory profile and changes in levels of leukotriene B₄ (LTB₄) and a panel of Th1/Th2 cytokines in subjects with suspected occupational asthma (OA) following specific inhalation challenge (SIC) to high-molecular-weight (HMW) and low-molecular-weight (LMW) agents. MATERIAL AND METHODS Fifty-one consecutive subjects undergoing SI...
results according to the results there is a significant statistical difference between average numbers of models before and after educational intervention (p < 0.001). also hba1c and fbs after educational intervention were lower (p < 0001). conclusions applying the hbm model proved is very effective in developing an educational program for diabetics, to control their blood sugar. besides such p...
