Borexino is a solar neutrino experiment located under the Gran Sasso mountain in Italy. It is currently in the commissioning phase and will start taking data in 2007. Its main goal is to detect low-energy neutrinos coming from the sun in real-time, via the scattering reaction ν e − → ν e−. Borexino exploits 300 tons of liquid scintillator as active target for neutrinos and 2200 photomultiplier ...

Abstract Recent efforts coupling our Sun-to-Earth magnetohydrodynamics (MHD) model and lower-corona magnetofrictional (MF) are described. Our Global Heliospheric MHD (GHM) uses time-dependent three-component magnetic field data from the MF as boundary values. The data-assimilation techniques to introduce vector Solar Dynamics Observatory/Helioseismic Magnetic Imager, hence a whole this simulati...

We discuss features of coronal mass ejections (CMEs) that are specific to heliospheric observations at large elongation angles. Our analysis is focused on a series of two eruptions that occurred on 2007 January 24-25, which were tracked by the Heliospheric Imagers (HIs) onboard STEREO. Using a three-dimensional (3-D) magneto-hydrodynamic simulation of these ejections with the Space Weather Mode...

Solar energy is one of the greatest assets human kind has ever got. It’s free of cost and available abundantly over the earth surface. Today peoples are looking for alternate source of energy which can fulfill our demands and can satisfy our day to day needs. In developing countries like India we need energy to cope up with industrial requirement and increasing population. Still many parts of I...

For over 4 billion years, solar radiation has played a profound role in driving the physical circulation of the atmosphere, the oceans, and the biological processes responsible for sustaining life on Earth. The angular distribution of, and diel and seasonal changes in, solar radiation are dictated by the relation of Earth’s axis to the Sun, the orbital angular velocity of Earth, and the gravita...

background: adverse effect of sun rays mainly uv ray on the human eye documented and protection of eyes is necessary using different methods such as, sun glasses. sunglasses are designed in different colors. the aim of this study was evaluation of the effect of different colors of sunglasses on the visual acuity, contrast sensitivity, stereopsis and color vision. methods: 81 normal subjects wer...
