On MHD waves, fire-hose and mirror instabilities in anisotropic plasmas
Temperature or pressure anisotropies are characteristic of space plasmas, standard magnetohydrodynamic (MHD) model for describing large-scale plasma phenomena however usually assumes isotropic pressure. In this paper we examine the characteristics of MHD waves, fire-hose and mirror instabilities in anisotropic homogeneous magnetized plasmas. The model equations are a set of gyrotropic MHD equat...
متن کاملDrinking from the fire hose--statistical issues in genomewide association studies.
T he past 3 months have seen the publication of a series of studies examining the inherited genetic underpinnings of common diseases such as prostate cancer, breast cancer, diabetes, and in this issue of the Journal, coronary artery disease (reported by Samani et al., pages 443–453). These genomewide association studies have been able to examine interpatient differences in inherited genetic var...
متن کاملHellinger and Matsumoto : Oblique Alfvén Fire Hose a 5 - 10 , 521
Two instabilities could take place in plasma with a bi-Maxwellian proton distribution function with Tp‖ > Tp⊥, where Tp‖ and Tp⊥ are proton temperatures, parallel and perpendicular, respectively, to the background magnetic field. The first instability is the fire hose (or whistler fire hose), generating low-frequency whistler waves at parallel propagation. We found a new, second instability, th...
متن کاملThe effect of fire on vegetation diversity indices, a case study: Sirachal research station
Fire affects vegetation and changes plant succession. In this paper, the vegetation of Sirachal Research Station, which burned in the summer of 2014, was studied and compared with the unburnt areas, based on biodiversity indices. The research was implemented as a factorial experiment in a completely randomized design. First, on the basis of physiognomy, the area was divided into three parts: sh...
متن کاملForest Fire Research in Finland
Effective wildfire suppression and diminished use of prescribed burning in forestry has clearly eliminated the role of fire in Finnish forest ecosystems as compared to pristine stands. The reintroduction of fire back to nature has therefore been suggested in various instructions, forest certification and forest conservation programmes. At the same time it is recognized that possible climate cha...
