OVER three-hundred and thirty years ago, just when England was about to be rent apart by the Civil War, Thomas Browne, a student of Padua and Montpellier and a Doctor of Medicine of both Leiden and Oxford, wrote Religio Medici. This contributed little to religion, but in the stately prose of a bygone age ranged far and wide with protestations of piety and a gentle irony. One of the best known p...

Photoelectron-photofragment coincidence ~PPC! spectroscopy has been used to study the dissociative photodetachment of H2O2 2 and D2O2 . The observed partitioning of photoelectron and photofragment translational energies provides information on the dynamics in the transition state region of the reaction between two hydroxyl radicals: OH1OH→O(P)1H2O. The data reveal vibrationally resolved product...

derik geothermal region has area of 242 km2 and is located 10 km to the west of salmas city in west azarbaijan province of iran. the most outstanding surface manifestations of geothermal energy in this region are three warm springs and outcrops of travertine deposits and quaternary basalt outcrops around warm springs. temperature range of warm springs varies from 31 to 32.6 °c. we visited and s...

The development of new practices in nuclear research reactor safety aspects and optimization recent reactors needs knowledge on forced convective heat transfer within sub-channels formed between several fuel rods or exchanger tubes, not only the fully developed regime but also developing laminar flow regime. main objective this was to find a correlation equation for calculating coefficient vert...

9.1 Background to Proton Therapy The use of proton beams for radiation treatment was proposed by Robert R. Wilson in 1946 [286]. Wilson referred to the ballistical aspects of the proton beam dose distribution as a rationale for the new modality. Heavy charged particles such as protons produce an energy deposition profile in tissue which is superior to profiles attainable using photon or electro...
