57. Ionization in Earth’s atmosphere near polar regions following the solar storm on January 20, 2005

Dr Achara Seripienlert (Division of Physics, Faculty of Science and Technology, Rajamangala University of Technology Thanyaburi, Pathum Thani 12110, Thailand, National Astronomical Research Institute of Thailand (NARIT), Chiang Mai 50200, Thailand)

Oral presentaion

Cosmic-ray induced ionization in the lower atmosphere (below ~ 15 km) is mainly caused by Galactic cosmic rays. However, some strong solar events can produce high energy ions with large intensity, which can penetrate to the lower atmosphere and produce significant ionization. We have modeled this effect for the solar storm of 20 January 2005, one of the strongest solar particle events ever...

Oral presentaion

It is required equipment and technique for measuring of global solar radiation and its component in many regions. There are financial difficulties in limited solar radiation measurement especially in developing countries. In this study, Angstrom-Prescott model could be employ to estimate solar radiations for 11 stations in Thailand. The empirical coefficients have been determined by five...

Oral presentaion

The Princess Sirindhorn Neutron Monitor at Doi Inthanon, Thailand provides important information about high-energy cosmic rays from space. Both the neutron monitor (NM) and Bare (lead-free) neutron counters detect the variation of intensity in the interplanetary cosmic rays. In addition, the bare detector to neutron monitor count rate ratio (Bare/NM) provides information on the particle...

Oral presentaion

Effects of recurrent geomagnetic storms (RGSs) induced by high-speed solar wind streams (HSSs) and corotating interaction regions (CIRs) on variations in daytime equatorial electric field (EEF) during 2007-2010 have been investigated. The EEF data as derived from magnetometer data together with the solar wind plasma data reveal many events of striking long duration of oscillating (short-lived)...

186. Northern Thailand velocity structure from azimuthal tele-seismic receiver function studies

Oral presentaion

Northern Thailand (NT) can be classified as the earthquake prone area, there are many active faults cutting through the area. The largest earthquake in Thailand modern history was also occurred on one of the active fault zones in the area on May 5th, 2014. In order to correctly estimate the epicenter and magnitude of the local earthquake, seismic velocity profile of the area is necessary which...

161. Synthesis of Nitrogen-Rich Carbonaceous with High Porous Volume for Supercapacitor Application

Oral presentaion

The nitrogen (N)-rich carbonaceous material has gained remarkable interest fueled by their potential use as high energy density materials for electrical storage. Using this materials as primary components in supercapacitor electrode gives a superior ability to form double-layer charge coupling, therefore capacitance increase significantly. In this work, we introduce a novel method to convert...
