| 1 | 腹的洞的主要恶意的含纤维的 histiocytoma : CT 调查结果和病理学的关联显示文摘 AIM:To study computed tomography(CT)features of abdominal malignant fibrous histiocytoma(MFH)in various rare locations.METHODS:We retroprospectively identified cases of MFH involving the abdominal cavity.Particular attention was paid to details regarding imaging features and histological types.RESULTS:The study population consisted of seven men and one woman,with a mean age of 52.5 years.Seven patients had some physical symptoms,while one was incidentally detected.The sites of origin were liver(n=3),greater omentum(n=1),superior mesentery(n=1),ileum(n=1),right psoas muscle(n=1)and right kidney(n=1).With the exception of the ileum lesion,all were of huge size.The contour of the lesions was more or less clear.Foci of necrosis were present in six lesions(n=6).On plain CT scan,all lesions were hypo to iso dense.The lesion in the greater omentum was cystic.One lesion(n=1)showed significant enhancement and the cystic lesion showed mild peripheral enhancement.An abundance of blood vessels surrounding the mass was seen in two lesions(n=2)and both were of the inflammatory variety.Pathological examination revealed storiform-pleomorphic variety(n=4),inflammatory variety(n=3)and myxoid variety(n=1).Two of the patients with inflammatory MFH had a clinical presentation of fever and one was afebrile,however,blood investigations in all three showed leukocytosis.CONCLUSION:Primary MFHs of the abdominal viscera and gastrointestinal tract are generally huge soft tissue masses containing areas of low attenuation and mild to moderate contrast enhancement. | Bivek Karki | 2012 | World Journal of Radiology2012，4，4： | 15 |
| 2 | 胸导管的磁共振水成像研究显示文摘胸导管是体内最粗大的淋巴管,形态和位置常有变异,可分为多种类型。胸导管结构细长、位置隐蔽,对其成像存在困难。随着磁共振水成像的广泛应用,其在无创性检测胸导管方面显示出良好的前景,现就国内外有关胸导管磁共振水成像的临床应用及其研究进展予以综述。 | 陈朔 许乙凯 Bivek karki 陈杰 | 2012 | 国际医学放射学杂志2012，35，6： | 5 |
| 3 | 颅内动脉瘤的血管内栓塞治疗:历史回顾显示文摘1.Introduction Remarkable evolution of endovascular neurosurgery over the past few decades has brought an excellent transformation in the treatment of cerebrovascular diseases.Though aneurysm treatment was begun from the 19th century by means of Hunterian ligation,the concept of endovascular occlusion was first initiated by Luessenhop and Velasquez in 1964 using balloon catheter[1].Endovascular approach has turned out to be a miracle when Guido Guglielmi pioneered in detachable coils in 1990. | Tamrakar Karuna 段传志 Bivek Karki 龙霄翱 张炘 罗斌 李西锋 何旭英 权涛 | 2012 | 中华神经医学杂志2012，11，6： | 2 |
| 4 | Modelling and analysis of decentralized energy systems with photovoltaic, micro-hydro, battery and diesel technology for remote areas of Nepal显示文摘Remote areas of Nepal suffer from limited or no access to electricity.Providing electricity access in remote areas is one of the foremost challenges of any developing country.The purpose of this study is to develop and propose a reliable and low-cost model for electrification.The study presents an optimized choice between decentralized renewable-energy systems and grid expansion.Opting for an analytical method for the modelling and analysis of electrification options based on life-cycle cost(LCC)and economic distance limit,each energy system for varied load conditions is compared for a better option.A framework for energy-system selection based on available resources is proposed.It compares the grid-expansion option with potential isolated renewable-energy systems to ensure energy access to the area under consideration.Additionally,off-grid configurations that rely on renewable energy sources are also considered for the necessity of backup supply to ensure continuous power to the research area.Techno-economic assessment is carried out for different off-grid and hybrid configurations proposed in this study and their feasibility checks are carefully examined.Commercial efficacy of the proposed hybrid energy systems is assessed by comparing the life cycle and energy cost and by performing different additional sensitivity analyses.The study concludes that reduced generation cost supports the increasing penetration of electrification.The LCC for grid expansion is the most economical under high-load conditions,whereas for the isolated and sparsely settled populations with low-load conditions,photovoltaic power backed up with a diesel generator is the most economical. | Nawaraj Sanjel Bivek Baral | 2021 | Clean Energy2021，5，4： | 0 |
