0051: Acute coronary syndrome and diabetes mellitus in elderly patients

Coronary heart disease is the first cause of morbidity and mortality in diabetic patients. Its incidence in elderly patients increases with the increase of their life expectancy. The aim of our study was to evaluate the characteristics and the management of elderly patients with diabetes and compared this with non- diabetics patients.This is a comparative retrospective study of 204 elderly patients (>75 years) admitted for ACSin haguenau Hospital center in France, between August 2012 and August 2013. We compared 63 elderly patients diabetics (GI), with 141 elderly patients non-diabetic (GII)The mode age: 80years (GI), 82years (GII). A male predominance noted in the both groups. More risk factors in (GI): hypertension (p=0.002), dyslipidemia (p=0.034), while (GII) is more smoker (p=0.003). More comorbidities for (GI), especially high frequency of renal failure (p<0.001). Predominance of atypical pain in both groups. NSTEMI was predominant in the both groups. At coronary angiography, three-vessel involvement was more frequent in (GI). Percutaneous coronary intervention (PCI) is less used in theGI (62.7%) toGII (69.5%). Hospital complications were higher in diabetics particulary: renal failure (p=0.04). Evolution at6and12month ago shows a more predominance of complications in diabetics. The quality of life of nondiabetic is better than in diabetics. On the other hand, the quality of life of the diabetics after PCI was better to conventional therapy. Elderly diabetic patients are very high cardiovascular risk, characterized by the severity of coronary artery disease. Diabetics are treated less aggressively than non-diabetics yet that diabetics quality of life improves better with angioplasty in comparison with the conventional treatment

Monitoraggio ambientale e biologico dell’esposizione ad idrocarburi mono-aromatici ed a metil tert-butil etere in un gruppo di lavoratori addetti all’erogazione di carburanti

Lo studio è stato condotto per valutare gli indicatori biologici di esposizione a vapori di benzina in lavoratori addetti all’erogazione di carburante tramite un approccio combinato di monitoraggio ambientale e biologico. L’esposizione personale a benzene, toluene, etilbenzene e xilene (BTEX) e l’escrezione urinaria di BTEX, metil tert-butil etere (MTBE-U), degli acidi trans,transmuconico (t,t-MA) ed S-fenilmercapturico (S-PMA) e della cotinina sono stati valutati con tecniche cromatografiche accoppiate alla spettrometria di massa. I livelli di MTBE-U erano influenzati dalla sola esposizione professionale a vapori di benzina, mentre quelli di B-U ed S-PMA dipendevano da abitudine tabagica ed esposizione professionale

A high stability semiconductor laser system for a 88^{88}Sr-based optical lattice clock

We describe a frequency stabilized diode laser at 698 nm used for high resolution spectroscopy of the 1S0-3P0 strontium clock transition. For the laser stabilization we use state-of-the-art symmetrically suspended optical cavities optimized for very low thermal noise at room temperature. Two-stage frequency stabilization to high finesse optical cavities results in measured laser frequency noise about a factor of three above the cavity thermal noise between 2 Hz and 11 Hz. With this system, we demonstrate high resolution remote spectroscopy on the 88Sr clock transition by transferring the laser output over a phase-noise-compensated 200 m-long fiber link between two separated laboratories. Our dedicated fiber link ensures a transfer of the optical carrier with frequency stability of 7 \cdot 10^{-18} after 100 s integration time, which could enable the observation of the strontium clock transition with an atomic Q of 10^{14}. Furthermore, with an eye towards the development of transportable optical clocks, we investigate how the complete laser system (laser+optics+cavity) can be influenced by environmental disturbances in terms of both short- and long-term frequency stability.Comment: 9 pages, 9 figures, submitted to Appl.

49Cr: Towards full spectroscopy up to 4 MeV

The nucleus 49Cr has been studied analysing gamma-gamma coincidences in the reaction 46Ti(alpha,n)49Cr at the bombarding energy of 12 MeV. The level scheme has been greatly extended at low excitation energy and several new lifetimes have been determined by means of the Doppler Shift Attenuation Method. Shell model calculations in the full pf configuration space reproduce well negative-parity levels. Satisfactory agreement is obtained for positive parity levels by extending the configuration space to include a nucleon-hole either in the 1d3/2 or in the 2s1/2 orbitals. A nearly one-to-one correspondence is found between experimental and theoretical levels up to an excitation energy of 4 MeV. Experimental data and shell model calculations are interpreted in terms of the Nilsson diagram and the particle-rotor model, showing the strongly coupled nature of the bands in this prolate nucleus. Nine values of K(pi) are proposed for the levels observed in this experiment. As a by-result it is shown that the values of the experimental magnetic moments in 1f7/2 nuclei are well reproduced without quenching the nucleon g-factors.Comment: 13 pages, 8 figure

Rethinking the Building Envelope as an Intelligent Community Hub for Renewable Energy Sharing

The widespread use of electric vehicles is hampered by the lack of an adequate charging points network. Likewise, and depending on the use, there could be a lack of correspondence between energy use and production in buildings equipped with renewable energy production systems. For these reasons, a modular device, which could be fully integrated into the building envelope, has been developed. The aim of the project was both to regenerate the existing building envelope and to enhance the newest one, adding new functions. The main goal will be the support of the growth of an electric power-sharing attitude capable of promoting the widespread use of electric vehicles of electric vehicle (EV), supporting strategic actions to retrofit/convert a private building in shared spaces for EV mobility, ensuring enough coverage for charging devices and reducing costs for public administration
