1等径角挤压制备超细生物医用纯钛的静态力学性能和塑性(英文)显示文摘等径角挤压是制备超细晶和纳米晶材料最有效的工艺之一。由于工业纯钛具有极佳的生物相容性,因此它可用作生物植入体材料。然而,较低的静/动态强度是纯钛类材料的不足之处。利用等径角挤压工艺可消除此类缺陷。本文作者在室温和通道角为135°条件下进行3道次挤压得到2级工业纯钛试样(2级CP-Ti)。对经等径角挤压3道次的CP-Ti样品进行显微组织分析及拉伸、硬度、三点弯曲和夏比冲击等力学性能测试。样品的显微组织演变结果表明,经等径角挤压工艺后样品的粗晶组织转变成超细晶或纳米晶组织。此外,力学性能测试结果表明,等径角挤压工艺能显著提高工业纯钛的屈服强度、抗拉强度、弯曲强度、硬度和断裂韧度,因此用该工艺制得的钛可以作为金属合金的替代品用作生物医用材料。Reza NASERI Mehran KADKHODAYAN Mahmoud SHARIATI 2017Transactions of Nonferrous Metals Society of China2017,27,9:7

5Spatial optimization of soil and water conservation practices using coupled SWAT model and evolutionary algorithm显示文摘Soil and water conservation practices have been extensively used in effective watershed management.The impact of each conservation practice is site specific and dependent on the implementation site in the watershed.In order to select cost effective placement of conservation practices with high impact,a large number of spatial combinations is needed to be compared.In this study,an optimization model framework is presented to find cost effective solutions for sediment yield and runoff control in the Fariman dam watershed in the Northeast of Iran.This was accomplished by integrating soil and water assessment tool(SWAT)for simulation of watershed hydrology and multi objective genetic algorithm(NSGA-II)for spatial optimization of soil and water conservation practices.The optimized solutions provided a trade-off between the two objective functions.The final Pareto-optimal shows that the impact of soil and water conservation practices on sediment yield is more than stream flow.The trade-offs between the objective functions show that the implementation of the median cost can lead to a significant decrease of 22.1%in the amount of sediment yield,and 10%in stream flow.Also,percent change achieved through median cost is very close to percent reduction with the highest cost.Results of low cost solution show that the vegetative practices are a suitable economic scenario for soil and water conservation.The introduced framework can be adapted as a suitable tool for selecting cost effective conservation practices in different regions.Farzaeh Naseri Mahmood Azari Mohammad Taghi Dastorani 2021International Soil and Water Conservation Research2021,9,4:3
6Comparisons between glucose analogue 2-deoxy-2-(^(18)F)fluoro-D-glucose and ^(18)F-sodium fluoride positron emission tomography/computed tomography in breast cancer patients with bone lesions显示文摘AIM: To compare 2-deoxy-2-(^(18)F)fluoro-D-glucose(^(18)FFDG) and ^(18)F-sodium(^(18)F-NaF) positron emission tomography/computed tomography(PET/CT) accuracy in breast cancer patients with clinically/radiologically suspected or known bone metastases.METHODS: A total of 45 consecutive patients with breast cancer and the presence or clinical/biochemical or radiological suspicion of bone metastatic disease underwent ^(18)F-FDG and ^(18)F-fluoride PET/CT. Imaging results were compared with histopathology when available, or clinical and radiological follow-up of at least 1 year. For each technique we calculated: Sensitivity(Se), specificity(Sp), overall accuracy, positive and negative predictive values, error rate, and Youden's index. Mc Nemar's χ~2 test was used to test the difference in sensitivity and specificity between the two diagnostic methods. All analyses were computed on a patient basis, and then on a lesion basis, with consideration ofthe density of independent lesions on the coregistered CT(sclerotic, lytic, mixed, no-lesions) and the divergent site of disease(skull, spine, ribs, extremities, pelvis). The impact of adding ^(18)F-Na F PET/CT to the work-up of patients was also measured in terms of change in their management due to ^(18)F-Na F PET/CT findings. RESULTS: The two imaging methods of ^(18)F-FDG and ^(18)F-fluoride PET/CT were significantly different at the patient-based analysis: Accuracy was 86.7% and 84.4%, respectively(Mc Nemar's χ~2 = 6.23, df = 1, P = 0.01). Overall, 244 bone lesions were detected in our analysis. The overall accuracy of the two methods was significantly different at lesion-based analysis(Mc Nemar's χ~2 = 93.4, df = 1, P < 0.0001). In the lesion density-based and site-based analysis, ^(18)F-FDG PET/CT provided more accurate results in the detection of CT-negative metastasis(P < 0.002) and vertebral localizations(P < 0.002); ^(18)F-Na F PET/CT was more accurate in detecting sclerotic(P < 0.005) and rib lesions(P < 0.04). ^(18)F-Na F PET/CT led to a change of management in 3 of the 45 patients(6.6%) by revealing findings that were not detected at ^(18)F-FDG PET/CT. CONCLUSION: ^(18)F-FDG PET/CT is a reliable imaging tool in the detection of bone metastasis in most cases, with a diagnostic accuracy that is slightly, but significantly, superior to that of ^(18)F-Na F PET/CT in the general population of breast cancer patients. However, the extremely high sensitivity of ^(18)F-fluoride PET/CT can exploit its diagnostic potential in specific clinical settings(i.e., small CT-evident sclerotic lesions, high clinical suspicious of relapse, and negative ^(18)F-FDG PET and conventional imaging).Selene Capitanio Francesca Bongioanni Arnoldo Piccardo Claudio Campus Roberta Gonella Lucia Tixi Mehrdad Naseri Michele Pennone Vania Altrinetti Ambra Buschiazzo Irene Bossert Francesco Fiz Andrea Bruno Andrea DeCensi Gianmario Sambuceti Silvia Morbelli 2016World Journal of Radiology2016,8,2:3
