We discuss models of energetic particle acceleration, interactions and nonthermal emission in active starforming regions at different stages of their evolution. Powerful stellar winds and supernova explosions with intense energy release in the form of strong shock waves can convert a sizeable part of the kinetic energy release into energetic particles. The starforming regions are argued as a fa...
Abstract. This study represents the first detailed analysis of multi-year, near-surface turbulence observations for an urban area located in highly complex terrain. Using 4 years eddy covariance measurements over Alpine city Innsbruck, Austria, effects surface, orographic setting and mountain weather on energy mass exchange are investigated. In terms surface controls, findings Innsbruck accorda...
Alfvén waves have been invoked as an important mechanism of particle acceleration in stellar winds of cool stars. After their identification in the solar wind they started to be studied in winds of stars located in different regions of the HR diagram. We discuss here some characteristics of these waves and we present a direct application in the acceleration of late-type stellar winds.
[1] Abundant wind-related features occur along Spirit’s traverse into the Columbia Hills over the basaltic plains of Gusev Crater. Most of the windblown sands are probably derived from weathering of rocks within the crater, and possibly from deposits associated with Ma’adim Vallis. Windblown particles act as agents of abrasion, forming ventifacts, and are organized in places into various bed fo...
In mud houses in Wakara, Upper Volta, dichlorvos dispensers installed at the rate of one dispenser per approximately 500 cubic feet (14 m(3)) produced 70% or higher average kills of adult Aëdes aegypti, exposed overnight in screen wire cages suspended at levels of 6 feet (1.8 m) and 2 feet (0.6 m), for approximately three months during the wet season and four months during the dry season. Avera...
In this study, we have assessed the skill of decadal prediction boreal spring (March–May) and summer (June–September) Surface Air Temperature (SAT) over India its relation with Sea (SST) in National Centers for Environmental Prediction (NCEP) Climate Forecast System Version 2 (CFSv2) coupled model. The CFSv2 is compared CNRM (Centre de Recherches Météorologiques) model, which best among selecte...
conclusions in order to diminish the health impacts of particulate matter in khorramabad, health training for the public, especially for persons with chronic lung and heart diseases, the elderly, and children, should be conducted by health systems to encourage them to reduce their activities during dusty days. materials and methods the pm10 sampling was carried out with a high-volume sampler at...
Weather affects wildland fires at scales frommultiseasonal precipitation patterns and anomalies, through synoptic and mesoscale weather patterns, to convective scale motions including fire-induced winds. This work analyzed the first day’s growth of the 2012 High Park fire, which occurred in Colorado’s Front Range during widespread drought and an unseasonal June windstorm, assessing to what exte...
different patterns of pressure systems together with local factors, leads in generation, risingand spread of dust in west of iran. in this study, to investigate the factors causing the occurrence of dust inkermanshah province, 132 cases of dust phenomena (code: 06) were selected and analyzed using kermanshahsynoptic station data for the spring and summer seasons in a period of 5 years (2005-200...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
