temperature and precipitation are among important atmospheric parameters for watershed planning. assessment of temperature and precipitation trends is very important for future watershed planning. in this paper, trends of atmospheric parameters such as seasonal and annual temperature and precipitation were examined for the synoptic stations of bandar anzali, rasht, ramsar, babolsar and gorgan. ...

The subambient heat capacities of three (SrO),(CuO), inter-oxide samples with Y = y = I: I = 7. y=l; and u=l. y=2, were measured as a part of an investigation into the chemical thermodynamics of the high-T, superconducting system (lanthanum + strontium + copper + oxygen). No anomalous contribution to the heat capacity was observed over the experimental region. The heat capacity of the Sr,,Cu,,O...

During the Leidenfrost effect, a thin insulating vapor layer separates an evaporating liquid from hot solid. Here we demonstrate that layers can be sustained at much lower temperatures than those required for formation. Using high-speed electrical technique to measure thickness of water over smooth, metallic surfaces, find explosive failure point is nearly independent material and fluid propert...
