The Science of Stroke

Join us for our May Café, as Dr. Tanya Warwick discusses the Science of Stroke.

Dr. Warwick works at the Community Regional Medical Center as Medical Director of the Stroke Program, and is currently researching prevention techniques for people who have already experienced a subcortical stroke and prevention of the onset of heart attacks and strokes by targeting insulin resistance among patients who have experienced a stroke or TIA.

As with previous Café Scientifique presentations, we will be at Café Via, with dinner beginning at 6pm and the presentation at 7pm. Below is a pdf link and jpeg poster of May’s presentation.

Chemical-weathering rates of aquifers and soils: using sediment-age-dating and geochemical mass-balance techniques to understand how groundwater gets its geochemistry

Hey Cafénistas…this is not an April Fool’s joke!

Come join us for Café Scientifique April 1, 2013 with Beth Weiman as she discusses her research that examines how groundwater attains its geochemistry. An important aspect of sourcing and maintaining our water supply deals with understanding how usable fresh-water resources gain their natural geochemistries.  In not knowing from exactly where groundwater is gaining its geochemistry, the goal of this work tries to identify from where groundwater is gaining most of its geochemistry.  In South and Southeast Asia, where many developing countries have natural arsenic contamination in their groundwaters, some work suggests that arsenic is sourced from an aquifer’s overlying soils, while others surmise it to be due to weathering of the underlying aquifer matrix. Based on past research showing that “younger” material weathers faster than “older” material, one objective of this work was to test whether aquifer age was a determinant parameter in arsenic groundwater chemistry.

We will continue to meet at the Cafe Via, near Herndon and Blackstone, where dinner will be served from 6:00 PM onwards, with the talk to begin at 7:00 PM.

ALPR1-SL1: The Accident that Never Should Have Happened

Hey Cafénistas…Forget March Madness!

Come join us for Café Scientifique March 4, 2013 as Owen Gailar discusses the first nuclear reactor accident in the U.S. The  SL-1  reactor,  originally  named  Argonne  Low  Power  Reactor,  ALPR,  was designed  for  the  USA  Army  as  a  prototype  of  a  low-power,  300  kWe  boiling-water reactor plant to be used in geographically remote locations.  The SL-1 was accidentally destroyed in a prompt criticality accident caused by the accidental  ejection  of  a  control  rod  during  maintenance  operations,  followed  by a steam explosion causing the death of four people on January 3, 1961.

We will continue to meet at the Cafe Via, near Herndon and Blackstone, where dinner will be served from 6:00 PM onwards, with the talk to begin at 7:00 PM.
