J This note on the purification of the watersupply of the Lawrence Military Asylum, Sanawar, may prove useful to medical officers, by reminding them of the ease with which even very large quantities of water can be rendered fit for drinking purposes at a very low cost, and with the most primitive of apparatus, by means of bleaching powder. The water-supply of the Asylum is derived from a spring...

The student lead group Ecoalition secured a grant to promote water harvesting efforts around the University of Arizona (UA). One of the objectives of this grant was to create a georelational database of potential water harvesting sites around the UA campus. Students, faculty, and staff worked together to collect field data around the University to include in this database. Those involved in the...

Water Erosion Prediction Project (WEPP), a process based erosion model that computes spatial and temporal distributions of surface runoff, soil loss and sediment deposition from overland flow on hillslopes and soil loss and sediment deposition from concentrated flow in small channels. In the present study, surface runoff and soil loss were simulated in a mini watershed (57 ha) of Sitlarao water...

To obtain fundamental information for assessing water resources and predicting natural hazards caused by heavy rains, rain precipitation data in central Japan have been analyzed statistically and geostatistically using data of AMeDAS (Automated Meteorological Data Acquisition System) established by Meteorological Agency of Japan. The study area is the mountainous Chubu and plain Kanto districts...

[1] We examined the effects of snow, event size, basin size, and forest harvest on floods using >1000 peak discharge events from 1953 to 2006 from three small (<1 km), paired‐watershed forest‐harvest experiments and six large (60–600 km) basins spanning the transient (400–800 m) and seasonal (>800 m) snow zones in the western Cascades of Oregon. Retrospectively classified rain‐on‐snow events de...

We present light harvesting of aqueous colloidal quantum dots to nonradiatively transfer their excitonic excitation energy efficiently to dye molecules in water, without requiring ligand exchange. These as-synthesized CdTe quantum dots that are used as donors to serve as light-harvesting antennas are carefully optimized to match the electronic structure of Rhodamine B molecules used as acceptor...

4 Abstract — Satellite communication systems operating at Ku (12/14 GHz) and Ka band (20/30 GHz) frequencies are used for broadband multimedia and internet based services. At these frequencies, the signal will be affected by various propagation impairments such as rain attenuation, cloud attenuation, tropospheric scintillation, ionospheric scintillation, water vapour attenuation, and rain and i...
