Water Clusters and Health
Fri, Oct 07, 2005 @ 01:00 PM - 02:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Environmental Engineering SeminarSpeaker:Dr. Shui-Yin Lo
Director, Quantum Health Research Institute
Pasadena, CAAbstractDr. Shui-Yin Lo earned his Ph. D. in the department of physics at the University of Chicago in 1966. He is a noted author, inventor, and a faculty member at several major universities. He founded the Quantum Health Research Institute in 2003 and devoted himself to unifying the quantum theory for the advancement of human health.Both East and West acknowledge that water is the source of life. We propose more specifically that stable water clusters are the source of life. Stable water clusters are formed in phase transition from ordinary very dilute solution similar to the phase transition from conductor to superconductor, or iron to magnet. Electron microscope and atomic force microscope pictures are shown. Some novel properties of stable water clusters are discussed. It is further proposed that meridians in Chinese medicine are composed of these stable water clusters. "Qi" another central concept in Chinese medicine, is considered to be quantum oscillations on meridians. Public demonstration will be conducted to show the existence of external qi.Location: Kaprielian Hall (KAP) - 156

Engineering Issues in Watershed Management
Fri, Oct 14, 2005 @ 01:00 PM - 02:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker:Professor Jiin-Jen Lee, Ph.D.,P.E.Professor of Civil and Environmental Engineering
University of Southern CaliforniaAbstractA general overall view will be presented on the engineering issues in watershed management including precipitation, basin recharge, runoff, sediment and debris production, storage reservoirs, detention and debris basins, as well as water quality control of storm water. Some of the special characteristics of the watersheds in the southern California region will be discussed.The key results of a USC study on economic impact evaluation of the proposed storm water treatment for Los Angeles County will be summarized and discussed to illustrate its far reaching implications.Two recent USC graduate research studies on debris production will also be discussed. Results from a statistical model will be compared with results from an artificial Neural Network (ANN) model to show its applicability and limitations in watershed management.Location: Kaprielian Hall (KAP) - 156

Origins of CO2 and Its Accumulation in Sedimentary Basins

Covina, CA Abstract: The content of CO2 in natural gas is in a wide range from less than 0.1% to as high as 99.6%, and high CO2 concentrations (>20%) in natural gas are encountered in many sedimentary basins. The presence of CO2 would reduce the resource value by lowering methane content and increase the infrastructure to remove and dispose it from natural gas to prevent the corrosion. For the risk assessment of encountering high concentration of CO2 gases in natural gas accumulation in a specific sedimentary basin, gas geochemistry provides an effective tool to discriminate the different origins of CO2 in natural gas.
In general, there are four major sources for CO2 generation in sedimentary basins. They are organic matter decomposition (oil, kerogen ), thermal decomposition of carbonate minerals (calcite, dolomite and so on), mantle degassing/ exsolution from magmas and hydrocarbon oxidation by thermochemical sulfate reduction.
A successful model to identify different origins of CO2 in natural gas by means of gas geochemistry approach will be presented from the geological case study of Huanghua depression, China. CO2 content in natural gas has a so wide range from 30ppm to 99.6% in the depression that understanding high-content CO2 origin is of very significant importance both in economic and academic aspects. According to the characterization of gas geochemistry and the fault development, we have determined that CO2 in Huanghua depression has three kinds of origins, i.e. organic matter decomposition, carbonate decomposition and mantle degassing.
Also, it is the first time to successfully simulate petroleum-anhydrite reactions to generate H2S and CO2 in the laboratory and found that the presence of magnesium ions in solution is crucial for sulfate reduction. The complex formation of Mg(OH)2:MgSO4 in the co-existence of magnesium and sulfate ions results in increasing [H+] concentration of the solution at high temperature of laboratory's conditions. With Talc-silica as mineral buffering, we experimentally determined that the yield ratio of CO2/H2S in mole is about 1.33 while CaSO4 is almost totally reduced by octane in the presence of magnesium ion catalyst.Location: Kaprielian Hall (KAP) - 156
