26. Antiparticle identification studies for the PAMELA satellite experiment
Abstract : The PAMELA satellite experiment will soon be launched and during its 3 year mission perform measurement of charged particle fluxes in the cosmic radiation. PAMELA is specifically designed to identify antiprotons and positrons in the vast background of other charged particles. READ MORE

27. Light-dependent magnetoreception in zebra finches : - from behaviour to receptor
Abstract : It is well known that animals can use a wide variety of information sources to help them orient and navigate asthey move over short or long distances. Birds can rely on information from the sun, the skylight polarizationpattern, the stars, landmarks and the Earth’s magnetic field for orientation and navigation. READ MORE

28. A Simulation Approach to Plasma Waves
Abstract : Electrostatic waves in the form of Broadband Electrostatic Noise (BEN) have been observed inthe Earth’s auroral region associated with high geomagnetic activity. Their broad frequencyspectrum consists of three electrostatic modes, namely electron plasma, electron acoustic andbeam-driven modes. READ MORE

29. O+ heating, outflow and escape in the high altitude cusp and mantle
Abstract : The Earth and its atmosphere are embedded in the magnetosphere, a region in space dominated by the geomagnetic field, shielding our planet as it acts to deflect the energetic solar wind. Even though the atmosphere is protected from direct interaction with the solar wind it is indirectly affected by significant magnetosphere-solar wind interaction processes, causing constituents of the upper atmosphere to flow up into the magnetosphere.

30. Radar Signatures of Auroral Plasma Instability
Abstract : Incoherent scatter radars are powerful ground based instruments for ionospheric measurements. By analysis of the Doppler shifted backscatter spectrum, containing the signature of electrostatic plasma waves, plasma bulk properties are estimated. READ MORE
