Structural Investigation of K-Feldspar KAlSi3O8Crystals by XRD and Raman Spectroscopy: An Application to Petrological Study of Luc Yen Pegmatites, Ye…

2016

K-feldspars in pegmatites from Luc Yen gem mining area, Yen Bai province, Vietnam were studied by X-ray fluorescence, X-ray powder diffraction and the Raman spectroscopy. Chemical analysis determined the K-feldspars in the form of (K0:8909Na0:0388Ca0:002Pb0:0042Cs0:0024Rb0:0338)(Al0:9975Fe0:0053Ti0:0004)Si2:988O8. Both X-ray powder diffraction and Raman spectroscopy indicated Luc Yen K-feldspars as orthoclase phase. Together with the values of Al content of the T1 tetrahedral sites in orthoclase, it is understood that Luc Yen pegmatites are of young ages (Cenozoic) and shallow intrusive types.

Reduction of oxygen to H2O2 at carbon felt cathode in undivided cells. Effect of the ratio between the anode and the cathode surfaces and of other op…

2019

Abstract In the last years, the electrochemical conversion of oxygen to hydrogen peroxide at carbon felt has been largely studied in order to define a new route for the production of H2O2 and to optimize the electro-Fenton process, which is based on the cathodic generation of H2O2. In particular, many studies regarding electro-Fenton process were carried out in undivided cells in order to avoid the costs of the separator and to reduce the cell potentials. Hence, in order to optimize the cathodic conversion of oxygen to H2O2 in undivided cells, the effect of many parameters linked to the anodic process were here evaluated. In particular, it was demonstrated that the performances of the proce…

“Mel” ~ “fel”: il dolce e l’amaro della doppiezza in alcuni testi poetici mediolatini dei secoli XI-XIII

2021

In questa nota viene proposta una rassegna di testi poetici mediolatini dei secoli XI-XIII – in particolare le commedie elegiache e i componimenti misogini – nei quali compare l’opposizione metaforica, ossimorica e paronomastica "mel" ~ "fel", volta a stigmatizzare la doppiezza che sovente caratterizza i comportamenti degli uomini e, soprattutto, delle donne. This note proposes a review of Middle-Latin poetic texts of the 11th-13th centuries – in particular the elegiac comedies and the misogynistic compositions – in which the metaphorical, oxymorical and paronomastic opposition "mel" ~ "fel" appears, aimed at stigmatizing the duplicity that often characterizes the behavior of men and, above…

IRIDE: Interdisciplinary research infrastructure based on dual electron linacs and lasers

2014

This paper describes the scientific aims and potentials as well as the preliminary technical design of RUDE, an innovative tool for multi-disciplinary investigations in a wide field of scientific, technological and industrial applications. IRIDE will be a high intensity "particles factory", based on a combination of high duty cycle radio-frequency superconducting electron linacs and of high energy lasers. Conceived to provide unique research possibilities for particle physics, for condensed matter physics, chemistry and material science, for structural biology and industrial applications, IRIDE will open completely new research possibilities and advance our knowledge in many branches of sci…

Career opportunities and benefits for young oncologists in the European Society for Medical Oncology (ESMO)

2016

The European Society for Medical Oncology (ESMO) is one of the leading societies of oncology professionals in the world. Approximately 30% of the 13 000 ESMO members are below the age of 40 and thus meet the society's definition of young oncologists (YOs). ESMO has identified the training and development of YOs as a priority and has therefore established a comprehensive career development programme. This includes a leadership development programme to help identify and develop the future leaders in oncology. Well-trained and highly motivated future generations of multidisciplinary oncologists are essential to ensure the optimal evolution of the field of oncology with the ultimate goal of pro…

Iberian Distribution of the Freshwater Snail Genus Bithynia Leach, 1818 (Mollusca: Truncatelloidea), Vector of Opisthorchiasis and Metorchiasis

2021

Background: Opisthorchis felineus and Metorchis bilis are trematodes that cause opisthorchiasis and metorchiasis, respectively. The freshwater snails Bithynia hispanica and B. tentaculata are the respective intermediate hosts for these parasites in the Iberian Peninsula, where both parasites are present. Methods: To study the distribution of these snail species, an exhaustive literature review and revision of museum collections was performed. Results: A total of 370 localities were compiled and mapped. B. tentaculata were found throughout the Iberian Peninsula, both in Spain and Portugal, while B. hispanica was found only in the Mediterranean coast of Spain. Conclusion: Knowing the distribu…

Reverse versus Normal Prenyl Transferases in Paraherquamide Biosynthesis Exhibit Distinct Facial Selectivities

1999

Both a face-selective and a non-face-selective mode of formation of quaternary centers of isoprene-derived structural moieties of the natural alkaloid paraherquamide A (1) have been discovered by feeding experiments on Penicillium fellutanum with [U-13 C6 ]-glucose and [13 C2 ]-acetate. The labeling patterns suggest that the methyl groups (C22, C23) are introduced in a non-face-selective manner by a reverse prenyl transferase. The C5 unit comprising the dioxepin moiety retains stereochemical integrity indicative of a single, face-selective addition of the phenolic group to the dimethylallyl group.

Gender Confirmation Surgery: Guiding Principles

2016

Abstract Background At this time, no formal training or educational programs exist for surgeons or surgery residents interested in performing gender confirmation surgeries. Aim To propose guiding principles designed to aid with the development of formal surgical training programs focused on gender confirmation surgery. Methods We use expert opinion to provide a “first of its kind” framework for training surgeons to care for transgender and gender nonconforming individuals. Outcomes We describe a multidisciplinary treatment model that describes an educational philosophy and the institution of quality parameters. Results This article represents the first step in the development of a structure…
