It has been known that the fi rst reference of the word Bioethics in the twentieth century was due to German theologist Fritz Jahr in 1927. In that surprising paper Jahr, a protestant Lutheran university professor, proposes humble catholic deacon, Saint Francis of Assisi (1181-1226), as the fi rst discoverer of Bioethics in Western Civilization. At the same time, Jahr quotes K.C.F Krause, a Mas...

We use detailed income, balance sheet, and cash flow statements constructed for households in a long monthly panel in an emerging market economy, and some recent contributions in economic theory, to document and better understand the factors underlying success in achieving upward mobility in the distribution of net worth. Wealth inequality is decreasing over time, and many households work their...

Deep brain stimulation (DBS) leads with radially distributed electrodes have potential to improve clinical outcomes through more selective targeting of pathways and networks within the brain. However, increasing the number of electrodes on clinical DBS leads by replacing conventional cylindrical shell electrodes with radially distributed electrodes raises practical design and stimulation progra...

The R&D process in the pharmaceutical industry has a long and dynamic life then it is an ideal field of application for ROA. Actually, ROA implementation, as widely demonstrated in literature, is narrowed to very limited cases because its perceived complexity. This research wants to suggest a simplified method, respect the ones available in literature, that could foster the use of ROA: we built...

Raman optical activity (ROA) is a relatively new method combining the variability of scattering experiments with the structural sensitivity of chiral spectroscopy. Typically, ROA can be employed to determine absolute configuration (AC) of organic compounds, chiral metal complexes, and conformation of biologically relevant chiral molecules in solution. The present review covers the latest theore...

OBJECTIVE Anatomical stages of digital osteoarthritis (OA) have been characterized radiographically as progressing through sequential phases from normal to osteophyte formation, progressive loss of joint space, joint erosion and joint remodelling. Our study was designed to evaluate a physiological parameter, joint surface temperature, measured with computerized digital infrared thermal imaging,...

OBJECTIVE To describe the association between sex, age and rate of change in knee cartilage volume in adults. METHODS A total of 325 subjects (mean age 45 yrs, range 26-61) was measured at baseline and approximately 2 yrs later. Knee cartilage volume and bone size were determined using T1-weighted fat saturation magnetic resonance imaging (MRI). Height, weight, body mass index and radiographi...

By looking back on the history of Raman Optical Activity (ROA), the present article shows that the success of this analytical technique was for a long time hindered, paradoxically, by the deep level of detail and wealth of structural information it can provide. Basic principles of the underlying theory are discussed, to illustrate the technique’s sensitivity due to its physical origins in the d...

We propose a calculus, cCOA, combining, thus more expressive than each of, two orientation calculi well-known in QSR: Frank’s projection-based cardinal direction calculus, CDA, and a coarser version, ROA, of Freksa’s relative orientation calculus. An original constraint propagation procedure, PcS4c+(), for cCOA-CSPs is presented, which aims at (1) achieving path consistency (Pc) for the CDA pro...

Mid-IR vibrational circular dichroism (VCD) and the corresponding Raman optical activity (ROA) spectra of 1-amino-2-propanol and 2-amino-1-propanol in neat solution are compared to yield insight into the dominant structural sensitivity of each technique. The ROA spectra for these isomeric compounds are quite similar while their VCD spectra are substantially different. The contrast between the r...
