21. Methyl halide emission estimates from domestic biomass burning in AfricaM Iqbal Mead, M Anwar H Khan, Iain R. White, Graham Nicless, Dudley E Shallcross, 2008, izvirni znanstveni članek Opis: Inventories of methyl halide emissions from domestic burning of biomass in Africa, from 1950 to the present day and projected to 2030, have been constructed. By combining emission factors from Andreae and Merlet [2001. Emission of trace gases and aerosols from biomass burning. Global Biogeochemical Cycles 15, 955-966], the biomass burning estimates from Yevich and Logan [2003. An assessment of biofuel use and burning of agricultural waste in the developing world. Global Biogeochemical Cycles 17(4), 1095, doi:10.1029/2002GB001952] and the population data from the UN population division, the emission of methyl halides from domestic biomass usage in Africa has been estimated. Data from this study suggest that methyl halide emissions from domestic biomass burning have increased by a factor of 4-5 from 1950 to 2005 and based on the expected population growth could double over the next 25 years. This estimated change has a non-negligible impact on the atmospheric budgets of methyl halides.

29. High Energy Emission from Gamma Ray BurstsLili Yang, predavanje na tuji univerzi Opis: Gamma Ray Bursts (GRBs) are the most energetic explosions in the universe, and they have been proposed as the most promising candidate sources of ultra-high energy cosmic rays (UHECRs). As a result of interactions of UHECR within the host environment and during their propagation towards Earth, high energy neutrinos and photons are also expected from both prompt and afterglow emission. In this talk, I will review the standard theory of particle acceleration and production in a GRB fireball, and multi-wavelength and multi-messeger observations of GRB emission. I will present the prediction of PeV — EeV neutrino production and evidence of GeV gamma ray radiation, and the expected detection in IceCube, Pierre Auger Observatory and CTA (the next generation of Imaging Atmospheric Cherenkov Telescopes). The investigation of high-energy particles will provide insight into the nature and complicated mechanisms of GRBs.
