The present text is based on a set of lectures given as part of a post graduate course in fluid mechanics at the Department of Mechanics, KTH School of Engineering Sciences. The topic of kinetic gas theory was chosen as to broaden the students knowledge in the field of fluid mechanics in general. In particular the students should get a new perspective on the contiuum theory approach applied in ...

We solve the problem of a Bose or Fermi gas in d-dimensions trapped by δ ≤ d mutually perpendicular harmonic oscillator potentials. From the grand potential we derive their thermodynamic functions (internal energy, specific heat, etc.) as well as a generalized density of states. The Bose gas exhibits Bose-Einstein condensation at a nonzero critical temperature Tc if and only if d+ δ > 2, and a ...

background: the aim of this study was assessment the risk management status of waste anesthetic gases in academicals hospitals in iran to prevent from harmful effects of these gases on employees' health. methods: a descriptive-analytic study was designed in 2011. standard structured checklist developed by ecri institute (emergency care research institute) was applied. checklists were filled ons...

til very recently, scientists still deliberated whether human activity was altering the global climate. Specifically, was the release of greenhouse gases, which trap heat radiating from the earth’s surface, to blame? With scientific evidence mounting in favor of the affirmative, the discussion is now turning to what steps society can take to protect our climate. One solution almost certainly wi...
