OBJECTIVE: To investigate the diagnostic significance of lingual flange protrusion for liver metastasis of patients with malignant ***: The data of 191 patients with malignant neoplasia were analyzed. All photos of patients' tongue image were recorded and lingual flange protrusion was the positive standard. χ~2 test for paired data and Kappa test were used to determine the diagnostic value of lingual flange protrusion for metastatic liver cancer. Mann-Whitney U test was used to compare the levels of liver serolog-ical markers. The area under receiver operating characteristic curve(ROC) and logistic regression model were used to analyze the predictive values of lingual flange protrusion, alkaline phosphatase(ALP), and lactate dehydrogenase(LDH) ***: Patients with lingual flange protrusion had a higher risk of liver metastasis than those without it(P flange protrusion and traditional diagnostic criteria(P = 0.541). Kappa was 0.738(P flange protrusion was significantly correlated with increased serum ALP and LDH levels(P flange protrusion is better than ALP, LDH and the combination of ALP and LDH(P flange protrusion and ALP,lingual flange protrusion and LDH, and lingual flange protrusion, ALP and LDH are not better than lingual flange protrusion alone(P > 0.05).CONCLUSION: Lingual flange protrusion is a potential diagnostic marker for liver metastasis of patients with malignant neoplasia.

Three Dimensional FE Analysis on flange Bending for TC4 Alloy during Shear Spinning

引用

Journal of Materials Science & Technology 2006年第6期22卷 855-859页

作者： Xinyu LU Shihong ZHANG Hongliang HOU Jizhen LI Lixin ZHOU Zhiqiang LI Institute of Metal Research Chinese Academy of Sciences Shenyang 110016 China Beijing Aeronautical Manufacturing Technology Research Institute Beijing 100024 China

In this paper, the 3D elastic-plastic simulation was carried out by using finite element （FE） code according to the phenomena of flange keeping straight, bending towards headstock and bending towards tailstock in the shear spinning experiments for TC4 alloy. The simulation results for the three kinds of deformations of the flange agree well with the experimental results. So it is possible to explain the reason of flange bending by analyzing the strain vectors in the flange for the three kinds of deformation, which shows that it is important to apply the FE simulation technology for predicting the defects and optimizing the spinning process of TC4 alloys.

Maxillary denture flange and occlusal discrepancies of Vertex ThermoSens in comparison with conventional heat-cured denture base materials

引用

The Journal of Biomedical Research 2019年第2期33卷 139-144页

作者： Hanadi A.Lamfon Ibrahim M.Hamouda Maxillofacial and Oral Rehabilitation Department Umm Al-Qura University Conservative Dentistry Faculty of Dentistry Umm Al-Qura University Dental Biomaterials Faculty of Dentistry Mansoura University

This study was conducted to investigate the maxillary denture bases and occlusal discrepancies using the Vertex Thermosens in comparison with the conventional polymethyl-methacrylate materials. Twenty maxillary denture bases were prepared from the Vertex ThermoSens and a conventional heat-cured denture base materials. Acrylic maxillary second molars were arranged in their respective positions on the ridge. After curing of both types of denture bases, they were deflasked with their respective master casts. Reference points were prepared for measurements of the antero-posterior and cross-arch dimensions at the denture borders using caliper device. Furthermore, the teeth discrepancies were measured between reference points in the ligual aspect of the second maxillary molars. The recorded data was analyzed using SPSS statistical software version 20. The results showed initial shrinkage of both denture bases in the antero-posterior and cross-arch dimensions immediately after decasting. This contraction was compensated gradually during storage in water up to 2 weeks. Regarding the variable time, there was a significant difference between the tested materials. Moreover, the results revealed occlusal discrepancies and shifting of teeth inward immediately after decasting, followed by outward movement after storage in water for 2 weeks. Regarding the variables time and materials, there were significant differences. Both materials exhibited inward shrinkage in the antero-posterior and cross-arch dimensions immediately after decasting. Both denture bases showed inward shifting of teeth immediately after decasting, followed by outward movement after storage in water up to 2 weeks.

Plastic Deformation Mechanism in Double-Roller Clamping Spinning of flanged Thin-Walled Cylinder

引用

Chinese Journal of Mechanical Engineering 2018年第3期31卷 76-84页

作者： Shu-Qin Fan Sheng-Dun Zhao Chao Chen School of Mechanical Engineering Xi’an Jiaotong University

Double?roller clamping spinning(DRCS) is a new process for forming a thin?walled cylinder with a complex surface flange. The process requires a small spinning force,and can visibly improve forming quality and production e ciency. However,the deformation mechanism of the process has not been completely understood. Therefore,both a finite element numerical simulation and experimental research on the DRCS process are carried out. The results show that both radial force and axial force dominate the forming process of DRCS. The deformation area elongates along the radial direction and bends along the axial direction under the action of the two forces. Both the outer edge and round corner of the flange show the tangential tensile stress and radial compressive stress. The middle region shows tensile tangential stress and radial stress,while the inner edge shows compressive tangential stress and radial stress. Tan?gential tensile strain causes a wall thickness reduction in the outer edge and middle regions of the flange. The large compressive thickness strain causes material accumulation and thus,an increase in the wall thickness of the round corner. Because of bending deformation,the round corner shows a large radial tensile strain in addition. The inner edge of the flange shows small radial compressive strain and tensile strain in thickness. Thus,the wall thickness on the inner edge of the flange continues to increase,although the increment is small. Furthermore,microstructure analysis and tensile test results show that the flanged thin?walled cylinder formed by DRCS has good mechanical properties. The results provide instructions for the application of the DRCS process.

Compared with general circular flanges, flanges on conical shells have different configurations. In the Chinese national code GBISO, however, there are no related contents about flange design of this kind of type. So, it needs to study loads of flanges of this kind of type. This paper takes the flange connection of a wide angle diffuser in a transonic and supersonic wind tunnel as the background, according to the principles of flange design in Chinese national code GB150, combining the characteristics of flanges of a wide angle diffuser, the loads of flanges have been analyzed, and the equations of loads and their locations have been presented.

In order to establish the design method for T-shaped tensile connector with high strength bolt,the theoretical analysis is carried out. Firstly,it analyzes the performance of the connector and establishes prying force calculation model. Based on the model,prying force equation and function between bolt prying force and flange thickness is derived,and the min and max thickness requirement of flange plate under a certain tension load is then obtained. Finally,two simplified design methods of the connector are proposed,which are bolt pulling capacity method and flange plate bending capacity method.

Prosthodontic management of hemimandibulectomy patients to restore form and function-A case series

引用

World Journal of Clinical Cases 2017年第10期5卷 384-389页

作者： Deenadayalan Lingeshwar Rajendran Appadurai Ujjayanthi Sswedheni Challa Padmaja Government Royapettah Hospital

Surgical resection of mandible owing to benign,malignant neoplasm,osteoradionecrosis is common. The resection can be total or segmental depending on the lesion. Loss of mandibular continuity causes deviation of remaining mandibular segment towards the resected side and rotation inferiorly due to muscle pull and scar contracture affecting mastication and esthetics. Surgical reconstruction may not be always possible. Prosthetic rehabilitation plays a major role in these patients. This case series describes different types of guiding flange(GF) prosthesis with modifications for three hemimandibulectomy patients at different time interval after surgery. The article details GF prosthesis combined with physiotherapy to correct deviation of mandible thereby improving mastication,esthetics and speech and thus enhancing the quality of life.
