Beef meat promotion of dimethylhydrazine-induced colorectal carcinogenesis biomarkers is suppressed by dietary calcium [PDF]

open access: yes, 2007
Red meat consumption is associated with increased risk of colorectal cancer. We have previously shown that haemin, Hb and red meat promote carcinogen-induced preneoplastic lesions: aberrant crypt foci (ACF) and mucin-depleted foci (MDF) in rats.

Time-Dependent Invariants and Green's Functions in the Probability Representation of Quantum Mechanics [PDF]

open access: yes, 1998
In the probability representation of quantum mechanics, quantum states are represented by a classical probability distribution, the marginal distribution function (MDF), whose time dependence is governed by a classical evolution equation.

Investigating the CO2 laser cutting parameters of MDF wood composite material [PDF]

open access: yes, 2011
Laser cutting of medium density fibreboard (MDF) is a complicated process and the selection of the process parameters combinations is essential to get the highest quality of the cut section.

Photometry and the Metallicity Distribution of the Outer Halo of M31 [PDF]

open access: yes, 2001
We have conducted a wide-field CCD-mosaic study of the resolved red-giant branch (RGB) stars of M31, in a field located 20 kpc from the nucleus along the SE minor axis. In our (I, V-I) color-magnitude diagram, RGB stars in the top three magnitudes of the

Biomass-derived carbon materials for energy storage applications [PDF]

open access: yes, 2021
Energy storage systems are an essential link in the implementation of renewable energies and in the development of electric vehicles, which are needed to reduce our dependence on fossil fuels and the emission of greenhouse gases.

Electrical properties of biomorphic SiC ceramics and SiC/Si composites fabricated from medium density fiberboard [PDF]

open access: yes, 2011
A study has been made of the dependences of the electrical resistivity and the Hall coefficient on the temperature in the range 1.8–1300 K and on magnetic fields of up to 28 kOe for the biomorphic SiC/Si (MDF-SiC/Si) composite and biomorphic porous SiC ...

Modelling chemical abundance distributions for dwarf galaxies in the Local Group: the impact of turbulent metal diffusion [PDF]

open access: yes, 2017
We investigate stellar metallicity distribution functions (MDFs), including Fe and ${\alpha}$-element abundances, in dwarf galaxies from the Feedback in Realistic Environments (FIRE) project.

Application of CrAlN coatings on carbide substrates in routing of MDF [PDF]

open access: yes, 2007
This study deals with the development of Chromium Aluminium Nitride (CrAlN) hard coatings (by varying the nitrogen content in the plasma, the target bias voltage, the working pressure and the deposition time) and their characterization by physical and ...

The Metallicity Distribution Function of Field Stars in M31's Bulge

open access: yes, 2005
We have used Hubble Space Telescope Wide Field Planetary Camera 2 observations to construct a color-magnitude diagram (CMD) for the bulge of M31 at a location ~1.6 kpc from the galaxy's center.

Modelling the chemical evolution of the Galaxy halo [PDF]

open access: yes, 2013
We study the chemical evolution and formation of the Galactic halo through the analysis of its stellar metallicity distribution function and some key elemental abundance patterns.
