Pulse Pressure: An Independent Predictor of Coronary and Stroke Mortality in Elderly Females from the General Population

The aim of this paper is to evaluate whether pulse pressure is an independent risk factor for coronary and stroke mortality in 3282 subjects (1281 males and 2001 females) aged +/- 65 years, taking part in the CArdiovascular STudy in the Elderly (CASTEL). After dividing subjects into tertiles of pulse pressure, adjusted relative risk (RR) and confidence intervals (CI) for 14-year coronary and stroke mortality was evaluated for each tertile. Among females, coronary mortality rate was 2.7% in the first tertile of pulse pressure, 4.7% in the second (RR 1.38, 95% CI [1.15-2.66]) and 6.2% in the third (RR 2, CI [1.20-3.51]). Stroke mortality was 3.6%, 4.1% (RR 1.23, CI [1.02-2.23]) and 8.3% (RR 2.27, CI [1.37-3.74]), respectively. This trend was recognizable in normotensive, borderline and sustained hypertensive women, where mortality increased with rising pulse pressure. No relationship was found between pulse pressure and mortality in males. In elderly women, pulse pressure was a good predictor of coronary and stroke mortality, even superior to the label of hypertension. No matter how any given pulse pressure level was obtained, it was more predictive of both coronary and cerebrovascular mortality than belonging to a normo- or hypertensive category

INTEGRATING SPHERE DEVICE FOR ATTENUATING RADIATION

A radiation attenuation device, particularly for measuring the radiations themselves. The device consists of at least two integrating spheres reciprocalkly connected by means of respective communication ports preferably of variable dimension; one of the integrating spheres is an input integrating sphere presenting at least one input opening, also preferably of variable dimensions, for inputting an incident radiation beam in the sphere, and another one of the integrating spheres is an output integrating sphere presenting at least one output opening to allow the output of the appropriately attenuated incident radiation and where appropriate measuring instruments can be housed

Dispositivo a sfere integratrici per l’attenuazione di radiazioni

Un dispositivo di attenuazione per radiazioni, in particolare per fini di misurazione delle radiazioni stesse. Il dispositivo è costituito da almeno due sfere integratrici connesse tra loro mediante rispettive porte di comunicazione preferibilmente di dimensioni variabili; una delle sfere integratrici è una sfera integratrice d'ingresso presentante almeno una apertura d'ingresso, anch'essa preferibilmente di dimensioni variabili, per l'ingresso nella sfera di un fascio di una radiazione incidente, ed un'altra delle sfere integratrici è una sfera integratrice di uscita, presentante almeno una apertura di uscita per consentire l'uscita della radiazione incidente opportunamente attenuata e dove possono essere alloggiati degli opportuni strumenti di misura

Bulk heteojunction solar cells using a novel polybithiophene polymer

In this work we describe the preparation of BHJ organic solar cells using blend films of poly[4,4’-bis(alkylsulfanyl)-2,2’-bithiophene] (PST) and 1-(3- methoxycarbonyl)-propyl-1-phenyl-(6,6)C61 (PCBM). Photovoltaic cells were prepared with a layer sandwiched between electrodes with different work functions. We made a comparative study of the electrical behaviour of different devices to investigate the influence of different fabrication conditions (donor/acceptor ratio, solvent, layer thickness, device annealing, etc.)
