  • Well known and established techniques, which allow obtaining intense laser pulses, have led to the development of advanced laser system used in science and various industries. Often at times, they combine Q-switching and mode-locking techniques in a single device to achieve unprecedented average pulse powers (e.g. HiLASE, HiPER, ELI, NIF, LiFE) for scientific applications, such as secondary sources of EUV, X-ray or particles, or as inertial confinement fusion (ICF) drivers.

  • Over the next 100 years, climate models suggest that warmer temperatures will very likely lead to greater climate variability and an increase in the risk of hydrologic extremes, i.e., floods and droughts. Perhaps the most significant and likely impact is a change in the timing of runoff in watersheds with large amounts of winter snowfall as higher temperatures lead to an increase in the ratio of rain to snow, faster snowmelt runoff, and earlier loss of snow.

  • Desai et al. (2004) provide a meta-analysis of health effects from household solid fuel air pollution. Health effects were categorized by level of evidence from the research literature. Relative risk ratios associated with solid fuel use, relative to clean fuels such as LPG, were derived for each health outcome (table 3.1). 11 The national and global mortality and DALY estimates presented by WHO (2007) reflect the relative risk ratios in Desai et al, limiting the health effects to ALRI in children u5, and COPD and lung cancer in adult women and men. ALRI...
