Cytoprotective Mechanisms Mediated by Polyphenols from Chilean Native Berries against Free Radical‐Induced Damage on AGS Cells

Oxidative Medicine and Cellular Longevity, Volume 2017, Issue 1, 2017., 2017
The prevalence of cytoprotective mechanisms induced by polyphenols such as activation of intracellular antioxidant responses (ICM) and direct free radical scavenging was investigated in native Chilean species of strawberries, raspberries, and currants.

Bioassay Directed Isolation and Biological Evaluation of Compounds Isolated from Rubus fairholmianus Gard.

BioMed Research International, Volume 2014, Issue 1, 2014., 2014
The in vitro and in silico analysis of Rubus fairholmianus acetone extract for antioxidant, antiproliferative, and anti‐inflammatory activity led to the isolation of six compounds. Amongst all the six isolated compounds tested, 1‐(2‐hydroxyphenyl)‐4‐methylpentan‐1‐one (compound 1) and 2‐[(3‐methylbutoxy) carbonyl] benzoic acid (compound 2) were found ...

Modelling Spatio‐Temporal Relevancy in Urban Context‐Aware Pervasive Systems Using Voronoi Continuous Range Query and Multi‐Interval Algebra

Mobile Information Systems, Volume 9, Issue 3, Page 189-208, 2013., 2013
Space and time are two dominant factors in context‐aware pervasive systems which determine whether an entity is related to the moving user or not. This paper specifically addresses the use of spatio‐temporal relations for detecting spatio‐temporally relevant contexts to the user.

Combined Acquisition and Tracking Methods for GPS L1 C/A and L1C Signals

International Journal of Navigation and Observation, Volume 2010, Issue 1, 2010., 2010
As part of the GPS modernization, the GPS L1 C/A signal will be augmented by the L1C signal. With this improvement, for the first time, several signals from the same constellation will be available at the same frequency. In this paper, an acquisition method is implemented to combine the GPS L1 C/A and L1C signals before correlation.

Forest Fire Risk Assessment: An Illustrative Example from Ontario, Canada

Journal of Probability and Statistics, Volume 2010, Issue 1, 2010., 2010
This paper presents an analysis of ignition and burn risk due to wildfire in a region of Ontario, Canada using a methodology which is applicable to the entire boreal forest region. A generalized additive model was employed to obtain ignition risk probabilities and a burn probability map using only historic ignition and fire area data. Constructing fire

An Oceanographer's Guide to GOCE and the Geoid [PDF]

Ocean Science, 2006
Abstract. A review is given of the geodetic concepts necessary for oceanographers to make use of satellite gravity data to define the geoid, and to interpret the resulting product. The geoid is defined, with particular attention to subtleties related to the representation of the permanent tide, and the way in which the geoid is represented in ocean ...

Geoid model determination for the Hellenic area “Hellas Geoid 2023”

Acta Geodaetica et Geophysica, 2023
AbstractThe latest geoid model "HELLAS GEOID 2023" (HG2023) derived by the Hellenic Military Geographical Service is the most comprehensive model for the entire Hellenic area. Long-term gravity data, orthometric and geometric heights, seabed topography and a high-resolution digital terrain model were implemented in the calculations. Data evaluation and
