Rabeprazole sodium (RAB) is an anti-secretory agent which inhibits the enzyme H+/K+ ATPase, present in the stomach parietal cells. The aim of this work is to develop and validate a simple and fast ultraviolet spectrophotometric method (UV) for quantification of RAB in pharmaceutical formulation and compare it with a capillary electrophoresis (CE) one, previously validated. The UV technique was ...

Introduction During the last few years, our group has been interested in taking advantage of the wealth of knowledge on aryl ketone photochemistry with the goal of developing functional solid state materials. We envision the use of robust crystalline solids with tunable photochromic properties and adjustable lifetimes as valuable elements for the construction of optical switches, information st...

Question 1 First, we have that λ − λ − 2 = (λ + 1)(λ − 2). Therefore, it is true that the eigenvalues of the corresponding adjacency matrix come in pairs of additive inverse. However, notice that ± √ −1 are eigenvalues, and therefore the associated matrix cannot be symmetric (there would only be real eigenvalues). We conclude that no undirected graph can have the above characteristic polynomial...

The Planck mission François

These lecture notes discuss some aspects of the Planck1 mission, whose prime objective was a very accurate measurement of the temperature anisotropies of the Cosmic Microwave Background (CMB). We announced our findings a few months ago, on March 21st , 2013. I describe some of the relevant steps we took to obtain these results, sketching the measurement process, how we processed the data to obt...
