To determine the potential benefit of Dacron prostheses impregnated with silicon polymer, an elastomer-coated prosthetic graft (Intervascular [I]) was implanted in 30 patients with aortic occlusive arterial disease or infrarenal abdominal aortic aneurysm. These patients were compared with two other groups who underwent vascular reconstruction with either a knitted double-velour prosthesis (Meadow [M] or a knitted prosthesis (Bard-USCI [U]). The different prostheses were randomly allocated just prior to their insertion. Average blood loss was 1063.33 +/- 1065.69 ml for the I group, 888.33 +/- 575.85 ml for the M group, and 908.33 +/- 471.80 ml for the U group (NS). The duration of the operation was 160 +/- 56 minutes for the I group, 142 +/- 37 minutes for the M group, and 153 +/- 65 minutes for the U group (NS). The average follow-up was 12 months. As calculated by the actuarial method, primary patency at 36 months was 71.5% for the I group, 100% for the M group, and 98.2% for the U group (p < 0.001). Secondary patency was 73.7% for the I group and 100% for the M and U groups, respectively (p < 0.001). This study shows that the thrombogenicity of the elastomer-coated aortofemoral vascular prosthetic graft was significantly higher than that of the two other prostheses. Increased intraoperative blood loss and longer duration of operation were related to the aortic abnormality being treated (aneurysm or occlusion) rather than to the type of prosthetic graft being used.

Photovoltaic module measurements are predominantly taken by using pulsed solar simulators. However, significant errors can be generated when the existing simulators are applied to current high-efficiency crystalline silicon photovoltaic modules. This paper presents the design and implementation of a novel solar simulator featuring reflection-type light source and single long-pulse flash. The analysis and experimental study of the capacitance effect and the technical details of the simulator including reflection-type lamp house, xenon flash lamp power supply, and source-measure unit are introduced. The results show that the complete system achieves Class AAA performance in accordance with the international standard. The proposed simulator outperforms other similar products on the market and has been adopted by some well-known photovoltaic module manufacturers. The practical application demonstrates that this high-performance and cost-effective simulator is quite suitable for photovoltaic module production line.
