Long-term photometric monitoring of Messier 5 variables: II. Blazhko stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
The light curves of 50 RRab (RR0) stars in M5 collected in Paper I are investigated to detect Blazhko modulation. 18 Blazhko stars are identified, and modulation is suspected in two additional cases. ...
Long-term photometric monitoring of Messier 5 variables: I. Period changes of RR Lyrae stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
The period changes of 86 M5 RR Lyrae stars have been investigated on a one-hundred-year time base. The published observations have been supplemented by archival Asiago, Konkoly and Las Campanas photog...

Design installation a Prototype Geohazard Monitoring System
2010/10/21
The town of Machu Picchu, Peru, serves the >700 000 tourists visiting Machu Picchu annually. It has grown threefold in population in the past two decades. Due to the limited low-lying ground, construc...
Temporal variability of mineral dust concentrations over West Africa: analyses of a pluriannual monitoring from the AMMA Sahelian Dust Transect
Temporal variability mineral dust concentrations West Africa the AMMA Sahelian Dust Transect
2010/10/11
The Sahelian belt is known to be a region where atmospheric levels of suspended mineral dust are among the highest observed on Earth. In the framework of the AMMA (African Monsoon Multidisciplinary An...
Derivation of quantum master equation with counting fields by monitoring a probe
Derivation quantum master equation counting fields monitoring a probe
2010/10/21
We show a microscopic derivation of a quantum master equation with counting terms which
describes the electron statistics. A localized spin behaves as a probe whose precession angle monitors the net ...

Zonguldak Hardcoal Basin is the largest bituminous coal region in Turkey where extensive underground mining activity exists. Because of this activity subsidence effects have been experienced in differ...
Monitoring of temporal and spatial variations in fumarole helium and carbon dioxide characteristics at Poás and Turrialba volcanoes, Costa Rica (2001-2009)
helium isotopes carbon isotopes Central America Costa Rica volcano monitoring
2017/8/9
We report results of a 9-year monitoring program that took place from 2001 to 2009 of the helium and carbon isotope (3He/4He, δ13C) and relative abundances ratios (CO2/3He) of fumarole sites at Poás a...

UV irradiances Aura/Ozone Monitoring Instrument Brewer measurements El Arenosillo parameter influence
2010/8/16
The main objective of this study is to compare the erythemal UV irradiance (UVER) and spectral UV irradiances (at 305, 310 and 324 nm) from the Ozone Monitoring Instrument (OMI) onboard NASA EOS/Aura ...
Preliminary results of land subsidence monitoring project in Konya Closed Basin between 2006–2009 by means of GNSS observations
Preliminary results land subsidence monitoring project Konya Closed Basin
2010/10/20
One of the potential dangers that might arise as a result of bringing excessive amounts of groundwater to the surface of the Earth is land subsidence. Such surface deformations – these velocities may ...
An Online Parallel-Plate Wet Denuder System for Monitoring Acetic Acid Gas
Impinger Ion chromatography Air quality monitoring Acidic gas Indoor air
2016/3/29
In air environments, acetic acid gas may lead to irritations, generate pungent odor, and cause objects to corrode. This
paper examines an online parallel-plate wet denuder system to monitor gaseous a...
