1软骨母细胞瘤:射频消融术在部分病例中替代外科手术切除显示文摘目的证明射频(RF)消融可以安全有效地治疗有选择的软骨母细胞瘤(selected cases of chondroblastoma)。方法本研究得到机构伦理委员会批准,并符合HIPPA的要求。由于为回顾性研究,故未签署知情同意书。回顾性分析了1995年7月-2007年7月2个医学中心行射频消融治疗后经活检证实为软骨母细胞瘤的病例。在CT引导下进行单极RF消融,同时获得病变影像学资料。记录术前和术后1d症状。由病历记录获取长期随访情况。结果13例男性和4例女性经RF治疗(平均年龄17-3岁)。L.D.

2原发性恶性甲状腺淋巴瘤的诊断与治疗(英文)显示文摘原发性恶性甲状腺淋巴瘤是一种罕见病,约占甲状腺恶性疾病的1%-3%,甚至不到非何杰金氏淋巴瘤的1%。根据改良的Ann-Arhor分类法对原发性甲状腺淋巴瘤所下的定义,此类淋巴瘤或局限于甲状腺(ⅠE期),或累及甲状腺与其邻近的膈上淋巴结(ⅡE期)。原发性甲状腺淋巴瘤是一种异源性疾病,它包括许多淋巴瘤的特性。本文的重点在于原发性甲状腺淋巴瘤的诊断和治疗。Peter Meusers Britta Elo Andrea Wittig 2003The Chinese-German Journal of Clinical Oncology2003,2,4:3
3Woody species composition,diversity and structure of riparian forests of four watercourses types in Burkina Faso显示文摘Riparian forests are classified as endangered ecosystems in general,particularly in sahelian countries like Burkina Faso because of human-induced alterations and civil engineering works.The modification of this important habitat is continuing,with little attention being paid to the ecological or human consequences of these changes.The objective of this study is to describe the variation of woody species diversity and dynamic in riparian forests on different type of watercourse banks along phytogeographical gradient in Burkina Faso.All woody species were systematically measured in 90 sample plots with sides of 50 m × 20 m.Density,dominance,frequency and species and family importance values were computed to characterize the species composition.Different diver-sity indices were calculated to examine the heterogeneity of riparian forests.A total of 196 species representing 139 genera and 51 families were recorded in the overall riparian forests.The species richness of individuals with dbh ≥ 5cm increased significantly from the North to the South along the phytogeographical gradient and varied significantly between the different types of riparian forests.Similarity in tree species composition between riparian forests was low,which indicates high beta diversity and reflects differences in habitat conditions and topography.The structural characteristics varied significantly along the phyto-geographical gradient and between the different types of riparian forests.The diameter class distribution of trees in all riparian forests showed a reverse 'J' shaped curve except riparian forest of stream indicating vegetation dominated by juvenile individuals.Considering the ecological importance of riparian forest,there is a need to delineate and classify them along watercourses throughout the country.Oumarou Sambaré Fidèle Bognounou Rüdiger Wittig Adjima Thiombiano 2011Journal of Forestry Research2011,22,2:2

5Insights into the radial water jet drilling technology-Application in a quarry显示文摘In this context, we applied the radial water jet drilling(RJD) technology to drill five horizontal holes into a quarry wall of the Gildehaus quarry close to Bad Bntheim, Germany. For testing the state-of-the-art jetting technology, a jetting experiment was performed to investigate the influence of geological heterogeneity on the jetting performance and the hole geometry, the influence of nozzle geometry and jetting pressure on the rate of penetration, and the possibility of localising the jetting nozzle utilizing acoustic activity. It is observed that the jetted holes can intersect fractures under varying angles, and the jetted holes do not follow a straight path when jetting at ambient surface condition. Cuttings from the jetting process retrieved from the holes can be used to estimate the reservoir rock permeability. Within the quarry, we did not observe a change in the rate of penetration due to jetting pressure variations.Acoustic monitoring was partially successful in estimating the nozzle location. Although the experiments were performed at ambient surface conditions, the results can give recommendations for a downhole application in deep wells.Thomas Reinsch Bob Paap Simon Hahn Volker Wittig Sidney van den Berg 2018Journal of Rock Mechanics and Geotechnical Engineering2018,10,2:2
