Transition at the EPA

Risk assessment at the EPA: an agency self-exam.

The relation between the omega-3 index and arachidonic acid is bell shaped: synergistic at low EPA+DHA status and antagonistic at high EPA+DHA status.

INTRODUCTION The relation between docosahexaenoic (DHA) and eicosapentaenoic (EPA) vs. arachidonic acid (AA) seems characterized by both synergism and antagonism. MATERIALS AND METHODS Investigate the relation between EPA+DHA and AA in populations with a wide range of EPA+DHA status and across the life cycle. EPA+DHA and AA were determined in erythrocytes (RBC; n=1979), umbilical arteries (UA...

Measurements at Epa of Vacuum and Electron-cloud Related Effects

In the LHC, in addition to the molecular photodesorption due to synchrotron radiation, an electron cloud will produce a significant gas load due to electron stimulated desorption. This electron cloud build-up is strongly dependant on the primary photoelectrons, secondary electron production and on the reflectivity of photons and electrons. The dependence of these phenomena on surface properties...
