Background: In this study, we aimed to compare the results of endovenous laser ablation (eVLA) and radiofrequency ablation (RFA) in patients with lower extremity venous insufficiency due to great saphenous vein (GSV) reflux on efficiency, patient comfort and postoperative morbidity. methods: endovascular approach in treatment of GSV insufficiency was performed in 283 patients between 2011 and 2014 at our clinic. In group 1, eVLA was performed on 149 patients (42 male, 107 female;mean age 46.90 ± 11.43) and in group 2, RFA was performed on 134 patients (41 male, 93 female;mean age 47.02 ± 12.58). The results were compared in terms of local pain, ecchymosis, paresthesia, venous clinic severity score (VCSS), length of GSV that process performed, efficiency and Clinical etiology Anatomy Pathophysiology (CeAP) classification data. Results: GSV diameter at saphenofemoral junction level was 10.65 ± 3.72 mm and 11.29 ± 3.78 mm in group 1 and 2, respectively. Length of GSV that process performed was 38.97 ± 6.88 cm in group 1 and 41.83 ± 4.82 cm in group 2. Postoperatively burn, pulmonary embolism (Pe) and deep venous thrombosis (DVT) were not observed in both groups. Postoperative complications in group 1 were hematoma formation in 2 (1.3%) patients, ecchymosis in 13 (8.7%) patients, edema in 21 (14.1%) patients and paresthesia in 10 (6.7%) patients. Postoperative complications in group 2 were hematoma formation in 1 (0.7%) patient, ecchymosis in 8 (6%) patients, edema in 12 (9%) patients and paresthesia in 6 (4.5%) patients. The efficiency of the process was 96.6% in eVLA group and 98.5% in RFA group. Conclusion: We conclude that both RFA and 1470 nm radial fiber eVLA procedures are effective and reliable techniques in treatment of GSV insufficiency. No significant difference was found between two techniques in terms of efficiency and postoperative morbidity.

Reliable and basic information on fish are required for the sustainable management of a fishery. For this reason, the fish fauna of the future reservoir of Ouessa in the low section of the mouhoun River, Burkina Faso is studied. In order to describe the fish community, the fish were sampled in march 2020 thanks to cast nets and gill nets. They were sorted into species and each fish was weighted at the nearest 0.1 g and its total length measured at the nearest mm. The landings of commercial fishermen were also observed. In total, 1059 fishes were collected and grouped into 42 species, 27 generas and 16 families. The dominant species were Synodontis nigrita, Synodontis schall, marcusenius senegalensis, Schilbe intermedius, Brycinus nurse and Alestes baremoze. However, the compilation of diverse sources suggests the presence of nearly 70 species. The index of Shannon-Weaver (3.97), the values of the condition factor, the fish size and the presence of intolerant species indicate the relatively good conditions of the aquatic ecosystem. Among the 24 dominant species, 54% have a positive allometric growth, 42% a negative allometric growth and 0.04 an isometric growth. This study builds the basis of sustainable management of the future reservoir of Ouessa that is planned to be the largest one of the country (40,000 ha large).

High spin states of the odd proton nucleus 123I have been populated in the reaction 116Cd(14N, 5n2p) at a beam energy of 65meV. Two previously known positive-parity ΔI = 2 sequences have been extended up to 31/2+ and 41/2+. In addition, a number of ΔI = 1 transitions linking the two ΔI = 2 sequences have been observed. It is suggested that both the ΔI = 2 sequences are built upon the oblate πg7/2[404]7/2+ Nilsson configuration.

本文探讨对压阻式加速度计所测得的人体加速度信号进行处理以估计人在体力活动中能耗的方法。受试者为12名青年女子。试验是在电动实验台上以3.7～5.9公里的时速步行。加速度计成对安装在后腰部,分别处于X轴(前后)和Z轴(上下)方向上。受试人步行中消耗的氧气被同步测得作为能耗的度量。数据采集与处理由一台386微机完成。实验表明运用压阻式传感器作为运动传感器可望在测能耗的同时估计身体的方向及其他运动特征。比较数据处理的方法按其与能耗之间的相关系数γ值来衡量。三种修正方法即基线法、参考法和不修正,当以加速度的RmS值作为测量参数时γ~2值分别为0.79,0.75和0.01,而三种测量参数即RmS、均值和峰值当以基线法对数据修正时γ~2值分别为0.79,0.79和0.70,步行中引入负重及上坡等条件时,加速度相对于能耗γ的~2值呈一致下降之势而不管采用何种测量参数或数据修正方式。比较表明,三种修正方式中以基线法最好;三种测量参数中RmS值和均值都优于峰值。

Three kinds of Al-11%Si (mass fraction) alloy samples with different processes were produced to investigate the effect of microstructures on its superplasticity. Among them, the as-eCAP sample pressed 16 passes has ultrafine grains (300 nm) and the finest secondary particles. The eCAP-T6 sample, with eCAP 16 passes followed by T6 treatment, has fine secondary particles (3 μm) but the largest grains (8 μm). Contrarily, the T6-eCAP sample, with T6 treatment followed by eCAP 16 passes, has ultrafine grains and the large secondary particles (7 μm). The tensile testing results show that the as-eCAP sample exhibits superplasticity at high strain rate of 5.75×10-1 s-1 due to its fine secondary particles and ultrafine grains. The eCAP-T6 sample, however, does not exhibit superplasticity at the same high strain rate of 5.75×10-1 s-1 because it has relatively large secondary particles and large grains. Remarkably, the T6-eCAP sample does not have superplasticity even at the lower strain rate of 1.15×10-1 s-1, attributing to its comparatively large secondary particles. When most secondary particles are larger than 7 μm, the high strain rate superplasticity could not be obtained even if this sample has ultrafine grains.

AIm: To determine the tolerability and safety profile of a low-dose maintenance therapy with 6-TG in azathioprine (AZA) or 6-mercaptopurine (6-mP) intolerant inflammatory bowel disease (IBD) patients over a treatment period of at least 1 ***: Database ***: Twenty out of ninety-five (21%) patients discontinued 6-TG (mean dose 24.6 mg; mean 6-TGN level 540 pmol/8×108 RBC) within 1 year. Reasons for discontinuation were GI complaints (31%), malaise (15%)and hepatotoxicity (15%). Hematological events occurred in three patients, one discontinued treatment. In the 6-TG-tolerant group, 9% (7/75) could be classified as hepatotoxicity.

The recently reported hepatotoxicity is worrisome and 6-TG should therefore be administered only in prospective trials.

Rainfall, throughfall and stemflow were measured and canopy interception loss was derived for 14 rainfall events from June 22 to August 30, 2008 within a mature declining hybrid white spruce （Picea glauca （moench） Voss x p engelmannii Parry ex engelm.） - subalpine fir （Abies lasiocarpa （Hook.） Nutt.） - lodgepole pine （Pinus contorta vat. latifolia Dougl. ex Loud.） stand in south-central British Columbia, Can- ada. Stemflow was negligible during the study period, while, respectively throughfall and canopy interception loss accounted for approximately 59.4% and 40.6% of the 50.1 mm of cumulative rainfall. Throughfall variability was assessed with three approaches involving roving and stationary wedge-type gauges, and stationary trough gauges. Throughfall exhibited large spatial variability with the coefficient of variability of study period throughfall sampled using 16 stationary trough gauges being 30.3%, while it was 38.0% and 28.7% for 32 stationary and 32 roving wedge gauges, respectively. Our analysis suggests that a roving gauge method is better than a stationary approach since the errors associated with event mean throughfalls are summed quadratically and a greater portion of the canopy area is sampled. Trough gauges were more efficient than wedge gauges; however, this efficiency was less than expected given their much larger sampling areas, suggesting that spatial autocorrelation lengths of throughfall may be longer than the trough systems. The spatial distribution of throughfall showed a high degree of temporal persistence throughout the study suggesting the existence of stable ＂wet＂ and ＂dry＂ inputs to the floors of these coniferous forests.

加速器驱动次临界系统(Accelerator Driven Sub-critical System,ADS)是最具潜力的下一代核能系统选型之一,准确评估ADS散裂靶内产生的长寿命放射性核素含量是应用研究中的重要课题,利用质子活化法可以有效评价质子与散裂靶材料发生相互作用产生长寿命核素的反应截面。4个质子辐照天然铅样品分别被能量为40 meV、70 meV、100 meV和400 meV的质子照射90 min、75 min、40 min和25 min,在冷却约20 a后,利用中国锦屏地下实验室(China Jinping Underground Laboratory,CJPL)的超低本底γ谱仪GeTHU进行测量,使用SAGe(Simulation and Analysis for Germanium experiments)模拟框架计算了GeTHU的探测效率,测定了能量为40 meV、70 meV、100 meV和400 meV质子与天然铅发生^(nat)Pb(p,x)^(207)Bi和^(nat)Pb(p,x)^(194)Hg反应的总产生截面,并与其他理论及实验工作的结果进行了比较,基于相同样品的实验测量结果在误差范围内保持一致,^(nat)Pb(p,x)^(207)Bi的反应截面与TeNDL的评价截面更为接近,^(nat)Pb(p,x)^(194)Hg的截面结果与INCL++/ABLA的理论预期保持一致,这些截面结果为ADS设施的放射性废物评估提供了实验依据。
