| 1 | DETERMINATION OF THE PARAMETERS OF SUPERPLASTIC FORMING FOR LONG RECTANGULAR THIN SHEET TITANIUM ALLOY Ti-6A1-4V显示文摘A method for determining the value of the strain rate sensitivity parameter m, of a thin sheet superplastic material, which is based on the results of constant gas pressure tests, has been developed in this paper. Unlike the conventional procedures the method involved provides the test conditions similar to those occurring during an industrial technological process. Such an approach enables one to estimate reliable the superplas- tic properties of the material under study. Theoretical analysis is based upon use of the standard equations of the membrane theory. The experimental investigations have been carried out for Ti-based alloy VT6 (Ti--6Al-4V). Theoretical predictions show satisfactory agreement with experimental data. The results obtained are compared with those measured by means of standard procedures (constant cross-head velocity experiments and load relaxation tests). It is shown that the use of specimens having reduced gage length (which is less than specimen’s width) could lead to considerable errors in experimental estimation of the m value which, in its turn, leads to inaccurate calculating the technological parameters. | R.

| 4 | Low-grade fibromyxoid sarcoma of the liver: A case report显示文摘BACKGROUND Low grade fibromyxoid sarcoma(LGFMS)is a rare and benign mesenchymal tumor with indolent course,most commonly found in young or middle-aged men.The majority of the LGFMSs are located in the trunk and deep soft tissue of the lower extremities.They appear as well circumscribed,although not encapsulated,which often leads to incomplete surgical resection.Despite their seemingly benign appearance,these tumors have aggressive behavior with high metastatic and recurrence rates.Accurate histopathologic examination of the specimen and its immunohistochemical analysis are mandatory for a precise diagnosis.CASE SUMMARY We report a case of a 38 year-old-man who presented with jaundice and upper abdominal discomfort.Multi-detector computed tomography and magnetic resonance imaging showed a large left liver tumor mass,extending to the hepatoduodenal ligament.Left hepatectomy was performed with resection and reconstruction of hepatic artery and preservation of middle hepatic vein.Histopathologic examination confirmed the tumor being a low-grade fibromyxoid sarcoma.Three and a half years after surgery,the patient died after being diagnosed with spine metastasis.CONCLUSION Due to poor response to all modalities of adjuvant treatment,we consider that the focus of treatment should be on surgery as the only option for curing the disease. | Vladimir Dugalic Igor I Ignjatovic Jelena Djokic Kovac Nikola Ilic Jelena Sopta Slavenko R Ostojic Dragan Vasin Marko D Bogdanovic Igor Dumic Tamara Milovanovic | 2021 | World Journal of Clinical Cases2021，9，1： | 1 |
