Classical bulges are centrally-concentrated, high surface density, three-dimensional stellar systems. Their high density could arise either because significant gaseous dissipation occurred during their formation, or could simply reflect formation at very high redshift (or some combination of these two, depending on the density). For illustration, equating the mean mass density within the lumino...

It was shown experimentally that ACTH causes an increase of cytoplasmic RNA and subcellular granules of the adrenal cortex shortly after administration. This effect was found to be concentrated primarily on the basophilic cytoplasmic granules and to be largely independent of cell division. The increase of nuclear RNA, DNA, and nuclear mass followed that of the cytoplasm. The observations indica...

An analytical method for the determination of N-nitrosodimethylamine (N-NDMA) in environmental aqueous samples has been developed using isotope dilution gas chromatography/mass spectrometry in the selected ion monitoring mode (GC/MS-SIM). After deuterated N-nitrosodimethylamine (d6-N-NDMA) as surrogate standard was added to the samples, the analytes were extracted with methylene chloride, dried...

Synopsis We are developing a software capable of aiding in evaluation of complex cluster mass spectra. Theoretical knowledge of characteristic isotopic pattern of each fragment is used to create a matrix of all fragments contained in the mass spectrum. Least squares routine is employed to find abundances of these fragments. Currently, efforts are concentrated on making the software efficient en...

This application note illustrates the advanced analytical performance and robustness of the Agilent 7700s/7900 ICP-MS for the direct determination of metallic impurities in high purity concentrated hydrochloric acid (HCl). The 7700s/7900 incorporates an Octopole Reaction System (ORS), which effectively removes polyatomic interferences, allowing ultimate detection limits to be achieved for eleme...

This application note illustrates the advanced analytical performance and robustness of the Agilent 7700s ICP-MS for the direct determination of metallic impurities in high purity concentrated hydrochloric acid (HCl). The 7700s incorporates a third generation Octopole Reaction System, the ORS3, which effectively removes polyatomic interferences, allowing ultimate detection limits to be achieved...

Vibration analysis for a cable with concentrated loads (mass) has been studied by many researchers under certain assumptions (e.g. see [1], [2]). This paper is to present an analytic method for analyzing sagged cables which have small equilibrium curvature and horizontal supports under both distributed and concentrated loads. The loads are applied at vertical as well as horizontal directions. C...

The graphene oxide (GO) is widely used as a graphene precursor. It has been recently evidenced that this object can form different lyotropic liquid crystals phases observed in highly anisotropic colloids. The confinement of GO sheets, a two-dimensional (2D) crystal is herein aim of study. The binary GO water is studied to describe the liquid crystallinity of concentrated dispersions, characteri...

Major problems can occur when liquid sloshes in a tank, such as storage tanks during an earthquake, and this is important engineering problem to address. To analyze phenomenon, the finite-element method generally used but involves many degrees of freedom tank large. In paper, nonlinear numerical model with relatively few established for vertical horizontal two-dimensional sloshing rectangular e...
