Loyalty Program in the Alcohol Beverage Industry: A Preliminary Look
In the United States the alcoholic beverage industry has created one of the largest markets in the world. Alcohol is a taxed and well-regulated product most profitable for large chain retailers who continuously dominate the industry. This research paper reports the story of loyalty programs throughout the beverage industries. Additionally, by analyzing a database of 107 top alcohol beverage retailers, this research paper provides a profile of the market trends for alcohol beverage retailers in the United States. Secondly, this research aims to shed light on how loyalty programs form a part of the current market trends in the alcohol beverage industry
HIGH RESOLUTION MASS SPECTROMETRIC STRATEGIES FOR DETECTION OF PROTEINS AND PEPTIDES COVALENTLY MODIFIED BY ELECTROPHILIC XENOBIOTICS AND ENDOGENOUS INTERMEDIATES
Non enzymatic protein covalent modifications are involved in the toxic effects induced by electrophilic xenobiotics as well as by endogenous cytotoxic oxidation by-products. Aim of my Ph.D work was to set-up MS methods for the identification, characterization and quantification of non-enzymatic covalently modified proteins and peptides in biological matrices. To reach this goal both tandem MS and high resolution approaches were employed due to the wealth of structural and molecular information that these techniques can provide.
As a first step the MS methods were applied for understanding in both in vitro and ex vivo conditions the mechanism of protein haptenation induced by amoxicillin (AX). The MS approach was then focused to study in ex vivo condition the covalent reaction between histidine dipeptides, such as carnosine, and toxic endogenous intermediates like reactive carbonyl species (RCS).
Distribution of red clump stars does not support the X-shaped Galactic bulge
CONTEXT. Claims of an X-shaped Galactic bulge were based on the assumption of
red clump stars as standard candles in some lines of sight crossing the
off-plane bulge. However, some doubts have been cast on whether the two peaks
in star counts along the line of sight really represent a double peak in the
density distribution, or whether there is something wrong with the assumption
of a unique constant absolute magnitude for all of these stars.
AIMS. With the advent of Gaia-DR2 parallaxes in combination with
near-infrared VISTA-VVV data, we are able to check which of the hypotheses is
correct.
METHODS. We calculated the median absolute magnitude corresponding to
both peaks of putative red clumps in seven lines of sight with the lowest
extinction in the interesting coordinates' range.
RESULTS. The difference between the absolute magnitude of the bright and the
faint peak is . The selected stars in both peaks cannot
be represented by the same red clump giants with constant .
CONCLUSIONS. The hypothesis that the bulge contains an X-shape is based on
the assumption that the faint and bright peaks of the density distribution
towards the bulge are dominated by standard red clump stars. However, we show
that both the faint and bright peaks cannot be dominated by standard red clump
stars simultaneously.Comment: 5 pages, accepted to be published in A&
A photometricity and extinction monitor at the Apache Point Observatory
An unsupervised software ``robot'' that automatically and robustly reduces
and analyzes CCD observations of photometric standard stars is described. The
robot measures extinction coefficients and other photometric parameters in real
time and, more carefully, on the next day. It also reduces and analyzes data
from an all-sky camera to detect clouds; photometric data taken
during cloudy periods are automatically rejected. The robot reports its
findings back to observers and data analysts via the World-Wide Web. It can be
used to assess photometricity, and to build data on site conditions. The
robot's automated and uniform site monitoring represents a minimum standard for
any observing site with queue scheduling, a public data archive, or likely
participation in any future National Virtual Observatory.Comment: accepted for publication in A
A simplified scheme for piezoelectric anisotropic analysis in human vertebrae using integral methods
This paper outlines a computational model for the analysis of the piezoelectric behaviour of the vertebral body remodelling process. Particular attention is paid to the algorithms for the simulation of the stress energy density for each point of the geometry and the distribution of the density in the bone. In addition, the model takes into account the piezoelectric effect and the anisotropy (transversal isotropy) of the bone. A model for internal anisotropic piezoelectric bone remodelling of a human vertebra is discussed in detail. The model consists of the implementation of an algorithm which includes the elastic and electric variables in a single equation using boundary element method. The presented results show a good agreement with biological data and the model does not include any electric additional charge.Peer ReviewedPostprint (published version
Performances of multi-gap timing RPCs for relativistic ions in the range Z=1-6
We present the performance of Multi-gap timing RPCs under irradiation by
fully stripped relativistic ions (gamma*beta=2.7, Z=1-6). A time resolution of
80 ps at high efficiency has been obtained by just using standard `off the
shelf' 4-gap timing RPCs from the new HADES ToF wall. The resolution worsened
to 100 ps for ~ 1 kHz/cm2 proton flux and for ~ 100 Hz/cm2 Carbon flux. The
chambers were operated at a standard field of E=100 kV/cm and showed a high
stability during the experiment, supporting the fact that RPCs are a convenient
choice when accommodating a very broad range of ionizing particles is needed.
The data provides insight in the region of very highly ionizing particles (up
to x 36 mips) and can be used to constrain the existing avalanche and
Space-Charge models far from the usual `mip valley'. The implications of these
results for the general case of detection based on secondary processes (n,
gamma) resulting in highly ionizing particles with characteristic energy
distributions will be discussed, together with the nature of the time-charge
correlation curve.Comment: 31 pages, 19 figures, submitted to JINS
