Magnesium is an abundant element in the environment. Magnesium ion sensing by fluorescence spectral method is of importance due to the need for the detection of the metal in the human body and the environment. In this paper, we report the Mg2+ ion sensing behavior of the phenylhydrazone derivative of a difluorenylpiperidin-4-one. The preparation method of this compound is simple. The compound s...

New results about the simulation of Resistive Plate Chambers are reported; particular enphasys is put in the understanding of charge spectra in regions where deviations from the pure avalanche mode of operation can be present. Presented by M. Abbrescia at the International Conference on Advanced Technology and Particle Phyisics, Villa Olmo, Como, Italy, 5-9 October 1998 Submitted to Nucl. Phys....

AIM To examine the possible influence of the MHC class II antigens alleles in the formation of the multinucleate aggressive giant cell tumour of bone. METHODS HLA class II antigen alleles were investigated in eight white patients from north east England with confirmed diagnosis of giant cell tumour of bone. All had locally aggressive, immunophenotypically HLA-DR negative giant cell tumours. ...

We examine the impact of population distribution on fertility in a nationally representative sample. We exploit detailed life-history data to conduct an event-history analysis of transition to first birth, examining mechanisms that might link migration and fertility: socialization, adaptation, selection, and disruption. Our multivariate analysis examines various socio-demographic traits, the pl...

We present mid-infrared imaging at 11.7 μm for the quadruple lens systems, PG1115+080 and B1422+231, using the cooled mid-infrared camera and spectrometer (COMICS) attached on the Subaru telescope. These lensed QSOs are characterized by their anomalous optical and radio flux ratios as obtained for (A1, A2) images of PG1115+080 and (A, B, C) images of B1422+231, respectively, i.e., such flux rat...

effects of atp and mg2+ concentrations on bioluminescence reaction of luciferase (photinus pyralis) were investigated by home-made luminometer. the michaelis constants of the enzyme for atp and mg2+ obtained from the lineweaver-burk graph, were 61.9 mm ±3.3 mm and 251.6mm ± 39.0mm respectively. optimum concentration of mg2+ for maximum luminescence was 0.004 m.
