| 1 | The relationship between viscosity and glass forming ability of Al-(Ni)-Yb alloy systems显示文摘The dynamic viscosity of Al-Yb and Al-Ni-Yb superheated melts was measured using a torsional oscillation viscometer. The results show that the temperature dependence of viscosity fits the Arrhenius law well and the fitting factors are calculated. The amorphous ribbons of these alloys were produced by the melt spinning technique and the thermal properties were characterized by using a differential scanning calorimetry (DSC). E (the activation energy for viscous flow), which reflects the change rate of viscosity, has a good negative relation with the GFA in both Al-Yb and Al-Ni-Yb systems. However, there is no direct relation between liquidus viscosity (ηL) and GFA. The superheated fragility M can predict GFA in Al-Yb or Al-Ni-Yb alloy system. | JIA Ran, BIAN XiuFang, Lü XiaoQian, SONG KaiKai & LI XueLian Key Laboratory for Liquid-Solid Structural Evolution and Processing of Materials (Ministry of Education), Shandong University, Jinan 250061, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，3： | 6 |
| 2 | Can tranexamic acid change preoperative anemia management during total joint arthroplasty?显示文摘AIM: To investigate the postoperative transfusion and complication rates of anemic and nonanemic total joint arthroplasty patients given tranexamic acid(TXA).METHODS: A cross-sectional prospective study was conducted of primary hip and knee arthroplasty cases performed from 11/2012 to 6/2014. Exclusion criteria included revision arthroplasty, bilateral arthroplasty, acute arthroplasty after fracture, and contraindication to TXA. Patients were screened prior to surgery, with anemia was defined as hemoglobin of less than 12 g/d L for females and of less than 13 g/d L for males. Patients were divided into four different groups, based on the type of arthroplasty(total hip or total knee) and hemoglobin status(anemic or nonanemic). Intraoperatively, all patients received 2 g of intravenous TXA during surgery. Postoperatively, allogeneic blood transfusion(ABT) was directed by both clinical symptomsand relative hemoglobin change. Complications were recorded within the first two weeks after surgery and included thromboembolism, infection, and wound breakdown. The differences in transfusion and complication rates, as well as the relative hemoglobin change, were compared between anemic and nonanemic groups.RESULTS: A total of 232 patients undergoing primary joint arthroplasty were included in the study. For the total hip arthroplasty cohort, 21%(18/84) of patients presented with preoperative anemia. Two patients in the anemic group and two patients in the nonanemic group needed ABTs; this was not significantly different(P = 0.20). One patient in the anemic group presented with a deep venous thromboembolism while no patients in the nonanemic group had an acute complication; this was not significantly different(P = 0.21). For nonanemic patients, the average change in hemoglobin was 2.73 ± 1.17 g/d L. For anemic patients, the average change in hemoglobin was 2.28 ± 0.96 g/d L. Between the two groups, the hemoglobin difference of 0.45 g/d L was not significant(P = 0.13). For the total knee arthroplasty cohort, 18%(26/148) of patients presented with preoperative anemia. No patients in either group required a blood transfusion or had an acute postoperative complication. For nonanemic patients, the average change in hemoglobin was 1.85 ± 0.79 g/d L. For anemic patients, the average change in hemoglobin was 1.09 ± 0.58 g/d L. Between the two groups, the hemoglobin difference of 0.76 g/d L was significant(P < 0.001). CONCLUSION: TXA administration results in low transfusion and complication rates and may be a useful adjunct for TJA patients with preoperative anemia. | Duy L Phan Joseph B Rinehart Ran Schwarzkopf | 2015 | World Journal of Orthopedics2015，6，7： | 5 |
| 3 | Correlation between liquid structure and glass forming ability in glassy Ag-based binary alloys显示文摘The atomic structures of liquid Ag-based binary alloys have been investigated in the solidification process by means of X-ray diffraction. The results of liquid structure show that there is a break point in the mean nearest neighbor distance r1 and the coordination number Nmin for glass-forming liquid, while the correlation radius rc and the coordination number Nmin display a monotone variational trend above the break point. It means glass-forming liquids have a steady changing in structure above liquidus and more inhomogeneous state at liquidus. We conclude that there is a strong correlation between liquid structure and glass forming ability in Ag-based binary alloys. | Lü XiaoQian, BIAN XiuFang, XIANG Nan & JIA Ran Key Laboratory for Liquid-Solid Structural Evolution and Processing of Materials (Ministry of Education), Shandong University, Jinan 250061, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，3： | 2 |
