Sensitivity Study of design Parameters of a Railway Route under Vertical deformations

Journal of Civil Engineering and Architecture 2014年第5期8卷 663-672页

作者： Luiz Fernando de Melo Correia Cassio Eduardo lima de Paiva department of Civil Engneering Universidade Estadual de Campinas (UNICAMP) Campinas 13083-970 Brazil

Studying the interaction of components is basic for a railroad project, which is also very important for creating maintenance procedures based on predictions from a model that assumes adequate performance. To determine these interactions, which can have a great number of combinations, the use of a computational model is of vital importance, in this case, the program FERROVIA 1.0 （RAILROAD 1.0） was used. A critical study developed the program FERROVIA 1.0, and its variables were characterized based on values observed in the literature. After initial characterization was carried out, a comparative study was performed on the sensitivity between these variables and the indications of significant behavior for a railway deformed by the known load of a wheel. A statistical program was used to correlate the elements. The intention was to launch the program FERROVIA 1.0 and later use it for 2,187 combinations. The data used in these correlations corresponded to the normal values for the elements used in railroad engineering practice. Our main goal is to understand the behavior of the track vertical deflection according to the variation of the scaling of the various elements of the railway,

Objective: To report atypical morphological features of Trichophyton(T.) tonsurans strains associated with tinea capitis. Methods: Eighty-two T. tonsurans strains isolated in Ceará, Brazil, were analyzed regarding macro and micromorphological features and nutritional patterns. Results: Fifty-two samples presented abundant chlamydoconidia, which were produced in chains. Macroscopically, these strains developed small glabrous colonies that were firmly attached to the surface of the culture medium, with few or no aerial mycelia and intense rusty yellow pigmentation. Seven strains did not grow with stimulus from thiamine. Samples were heterogeneous regarding urease production and none presented in vitro hair perforation. Conclusions: The observation of T. tonsurans strains with distinct phenotypic features indicates the need to revise the taxonomic criteria for routine identification of this dermatophyte.

在药物研发领域,野生动物的毒液正被广泛研究,许多基于毒液组分的研究以生物技术应用和专利申请形式被报道。巴西拥有丰富的生物多样性,公布的科研论文和专利申请数量显示了该资源是多么重要。本文报道了一份研究最透彻的巴西有毒动物物种清单及从2000年到2013年的专利申请情况,包括源自巴西有毒物种的毒液成份、毒素及其衍生物。分析了涉及物种的数据、产品类型与发明者的国籍。55个专利申请涉及8个种属,响尾蛇、南美巨蝮蛇、矛头蝮蛇、斜蛛占其中78%。其余22%的专利来自巴西游走蛛、巴西金幽灵蝎、巴西捕鸟蛛、叶水蛙的毒液研究。大多数的发明(42%)包括抗癌、免疫调节剂或抗菌的药物,13%的发明为抗毒血清和疫苗,11%为降压成分,9%为镇痛及抗炎成分,其它25%为一些技术和试剂盒。巴西发明家占专利申请比重的49%,而其它国家如美国、德国、俄罗斯和法国同样发表了巴西动物毒液、毒素或衍生物的专利。虽然巴西拥有着大多数有毒物种的专利,但这些专利主要属于其学校和研究机构,药物工业在这方面依然薄弱。迄今为止,在世界范围内,已将巴西的有毒物种运用于药物研发,但大多数的物种可否作为研发的重要工具,仍然需要作进一步的勘探。
