J. W. Reiner, L. Klein, A. Kapitulnik, T. H. Geballe, and M. R. Beasley Edward L. Ginzton Laboratories, Stanford University, Stanford, California 94305 (Received 13 March 1998) The reflectivity of the itinerant ferromagnet SrRuO3 has been measured between 50 and 25 000 cm21 at temperatures ranging from 40 to 300 K, and used to obtain conductivity, scattering rate, and effective mass as a functi...

La gestión del recurso hídrico es prioritaria en la agenda de Organización las Naciones Unidas. Tres vectores son esenciales, cantidad, calidad y escenarios cambio climático el hídrico. En región centro Tamaulipas, México, destaca red fluvial cuenca río Soto Marina, con los ríos Corona, Purificación Pilón, como principales tributarios. esta existen importantes volúmenes aguas residuales otros v...

The Mlech Water Treatment Plant (WTP) has produced 2,000 m3/day of drinking water using raw from Mlech, Kampot province. Since demand would be increased in the future, so that extension treatment capacity will main challenges correspondence with development planning PPWSA. balance estimation is also critical point order to make a good decision on WTP at existing area. Therefore, objectives this...

Palaeoclimatology provides our only means of assessing climatic variations before the beginning of instrumental records. The various proxy variables used, however, have a number of limitations which must be adequately addressed and understood. Besides their obvious spatial and seasonal limitations, different proxies are also potentially limited in their ability to represent climatic variations ...

A high-finesse optical cavity was employed to perform highly sensitive spectroscopy of molecular oxygen at wavelengths near 763 nm. An equivalent absorption length of ;1 km was obtained by a 26-cm-long optical cavity with a finesse of 6000. An extended cavity diode laser was frequency locked to the cavity, and pure absorption profiles were recovered by monitoring of the cavity transmission duri...

Here, we compare the ocean overturning circulation of early Eocene (47–56 Ma) in eight coupled climate model simulations from Deep-Time Model Intercomparison Project (DeepMIP) and investigate causes observed inter-model spread. The most common global meridional (MOC) feature these is anticlockwise bottom cell, fed by sinking Southern Ocean. In North Pacific, one (GFDL) displays strong deepwater...
