Objective: To study the outcome of normothermic beating heart pulmonary thromboendarterectomy (PTE) performed in patients with chronic pulmonary thromboembolism. Methodology: A retrospective analysis of 15 patients who underwent PTE under normothermic beating heart cardio-pulmonary bypass from July 2009 to September 2018 was done. The patients were followed up with clinical assessment, transthoracic echocardiography and computerized tomographicangiography (cTA) for 1 month to 82 months. Results: Data were analysed for 15 consecutive patients. Mean age of the patients was 35.28 years and 10 patients were male. Pre-operatively 6 (40%) patients presented with New York Heart Association (NYHA) class II dyspnoea on exertion symptomatology, 7 (47%) were in NHYA class III, and 2 (13%) were in NYHA class IV. The preoperative and postoperative mean pulmonary artery pressures (mPAP) (mmHg) were 36.50 ± 11.3 and 20.21 ± 7.19, the systolic PAPs (mmHg) were 73.35 ± 14.12 and 35.21 ± 7.89 and the diastolic PAPs (mmHg) were 19.28 ± 8.60 and 12.85 ± 7.26 respectively. 2 (13%) patients had Jamieson’s type I and 12 (87%) had Jamieson type II disease. One patient (7%) expired on 9th postoperative day. All the patients had improved pulmonary gas exchange and did not require oxygen supplementation from 5th postoperative day;symptoms improved to NYHA class I & II in 12 (80%) & 3 (20%) of patients respectively. There was no reperfusion pulmonary edema or any neurologic complications. Postoperative echocardiogram showed improved right ventricular function and computerised Tomographic Angiogram showed completeness of the procedure. conclusion: Pulmonary thromboendarterectomy under normothermic beating heart cardiopulmonary bypass has good immediate postoperative results with significant progressive improvement in hemodynamics and quality of life during the course of follow-up. The results were not only comparable to those of the procedure done under deep hypothermic circulatory arrest by ot

钢管混凝土(cFST)是由混凝土和钢管组成的复合结构。核心混凝土防止钢管局部屈曲,钢管对核心混凝土进行约束,钢管与核心混凝土之间的复合作用比空心钢管或钢筋混凝土柱具有良好的结构性能。钢管和混凝土的复合作用增加了构件的刚度。然而,即使此类结构具有高刚度和高承载能力,也发现cFST构件的寿命由于腐蚀效应而降低。不锈钢有耐腐蚀性、高的耐火性和延展性的特点。将混凝土填充到不锈钢管(cFSST)中,形成不锈钢管混凝土结构。但不锈钢管较普通的碳素钢材料价格高。为了降低工程成本,选择薄壁性不锈钢管,并采用加劲肋措施防止不锈钢薄壁管的屈曲。此外,再生骨料作为绿色环保性材料。将再生混凝土灌注与带有加劲肋的薄壁不锈钢管中,以其为对象进行试验研究,以研究其在轴向压缩中的行为和失效模式。共进行了16个带肋的薄壁不锈钢管再生混凝土试件在轴心荷载作用下(ScFSST)的力学性能,其中2个为无加劲肋试件,再生混凝土粗骨料替代率(r)取50%,2个试件为普通混凝土。宽厚比在75至125之间变化,不锈钢的加劲肋的宽度在25至60mm之间变化。管的厚度均为2mm,横截面为150mm至250mm,长度分别为450mm至750mm。使用c40的混凝土强度。所有加劲肋的厚度保持恒定(4mm)。本研究的主要目的是研究带肋的薄壁不锈钢管再生混凝土柱轴向压缩下的性能。得到其在轴向荷载作用下的破坏模式并获得其轴心受压承载力。结果表明,加劲肋的存在显着延迟了薄壁不锈钢管的局部屈曲,并且轴压承载力平均增加了6.94%,但试件延性略有降低,再生骨料取代率为50%的试件较普通混凝土试件承载力平均提高了10.9%。加劲肋的长度对试件承载力影响较小。本文选用了不同规范和文献对带肋薄壁不锈钢再生混凝土短柱进行了轴压承载力计算,并于试验实测的承载力进行对比。结果表明计算结果与实测结果均偏于安全,在后续的研究中,可以尝试推导适合于带肋薄壁不锈钢再生混凝土短柱轴压承载力的计算公式。

GaN/InGaN based violet light emitting diodes (LEDs), emitting at 430 nm, have been grown on conventional single side polished (SSP) and patterned sapphire substrates (PSS). characteristics of the epitaxial wafers and subsequently fabricated LEDs have been analyzed. The photoluminescence (PL) peaks have been observed at 428.1 nm 426.1 nm for the epitaxial layers on SSP and PSS respectively. The PL intensity is 2.9 times higher in the case of PSS. The electroluminescence (EL) peaks have been observed at 430.78 nm and 430.35 nm for the LEDs on SSP and PSS respectively. The light output from LED fabricated on the PSS is 2.15 times higher than that of the LED on SSP at a forward current of 100 mA.

Aims: To determine whether central corneal thickness (ccT) is a significant pr edictor of visual field and optic disc progression in open angle glaucoma. Metho ds: Data were obtained from a prospective study of glaucoma patients tested with static automated perimetry and confocal scanning laser tomography every 6 month s. Progression was determined using a trend based approach called evidence of ch ange (EOc) analysis in which sectoral ordinal scores based on the significance o f regression coefficients of visual field pattern deviation and neuroretinal rim area over time are summed. Visual field progression was also determined using t he event based glaucoma change probability (GcP) analysis using both total and p attern deviation. Results: The sample contained 101 eyes of 54 patients (mean (S D) age 56.5 (9.8) years) with a mean follow up of 9.2 (0.7) years and 20.7 (2.3) sets of examinations every 6 months. Lower ccT was associated with worse baseli ne visual fields and lower mean IOP in the follow up. In the longitudinal analys is ccT was not correlated with the EOc scores for visual field or optic disc cha nge. In the GcP analyses, there was a tendency for groups classified as progress ing to have lower ccT compared to nonprogressing groups. In a multivariate analy ses accounting for IOP, the opposite was found, whereby higher ccT was associate d with visual field progression. None of the independent factors were predictive of optic disc progression. conclusions: In this cohort of patients with establi shed glaucoma, ccT was not a useful index in the risk assessment of visual field and optic disc progression.
