A comprehensive method for the elastic calculation of the two-point wheel-rail contact

This work shows the method developed to solve the wheel-rail contact problem via a look-up table with a three-dimensional elastic model. This method enables introduction of the two contact point effect on vehicle movement using three-dimensional analysis of surfaces including the influence of the angle of attack. This work presents several dynamic simulations and studies the impact that the introduction of the two contact points on three dimensions has on wear indexes and derailment risk against traditional bidimensional analysis. Furthermore, it studies advantages and disadvantages of using a look-up table against an on-line resolution of the problem.

Evidence for classification of c.1852_1853AA > GC in MLH1 as a neutral variant for Lynch syndrome

Background: Lynch syndrome (LS) is an autosomal dominant inherited cancer syndrome characterized by early onset cancers of the colorectum, endometrium and other tumours. A significant proportion of DNA variants in LS patients are unclassified. Reports on the pathogenicity of the c.1852_1853AA>GC (p.Lys618Ala) variant of the MLH1 gene are conflicting. In this study, we provide new evidence indicating that this variant has no significant implications for LS. Methods: The following approach was used to assess the clinical significance of the p.Lys618Ala variant: frequency in a control population, case-control comparison, co-occurrence of the p.Lys618Ala variant with a pathogenic mutation, co-segregation with the disease and microsatellite instability in tumours from carriers of the variant. We genotyped p.Lys618Ala in 1034 individuals (373 sporadic colorectal cancer [CRC] patients, 250 index subjects from families suspected of having LS [revised Bethesda guidelines] and 411 controls). Three well-characterized LS families that fulfilled the Amsterdam II Criteria and consisted of members with the p.Lys618Ala variant were included to assess co-occurrence and co-segregation. A subset of colorectal tumour DNA samples from 17 patients carrying the p.Lys618Ala variant was screened for microsatellite instability using five mononucleotide markers. Results: Twenty-seven individuals were heterozygous for the p.Lys618Ala variant; nine had sporadic CRC (2.41%), seven were suspected of having hereditary CRC (2.8%) and 11 were controls (2.68%). There were no significant associations in the case-control and case-case studies. The p.Lys618Ala variant was co-existent with pathogenic mutations in two unrelated LS families. In one family, the allele distribution of the pathogenic and unclassified variant was in trans, in the other family the pathogenic variant was detected in the MSH6 gene and only the deleterious variant co-segregated with the disease in both families. Only two positive cases of microsatellite instability (2/17, 11.8%) were detected in tumours from p.Lys618Ala carriers, indicating that this variant does not play a role in functional inactivation of MLH1 in CRC patients. Conclusions: The p.Lys618Ala variant should be considered a neutral variant for LS. These findings have implications for the clinical management of CRC probands and their relatives.

Diseño estructural de un basculante de moto de competición

[ES]En este trabajo se plantea una propuesta de diseño estructural de un basculante de una moto de competición de 250cc y 4T adecuado a las normas de la competición MotoStudent entre universidades. En primer lugar se estudian los distintos tipos de basculante existentes y se ponderan sus ventajas e inconvenientes. Posteriormente se elige uno de los tipos en base a las características de la moto y se desarrolla. La herramienta utilizada para el desarrollo es el programa PTC Creo 2.0. Primero se realiza el diseño en CAD de la pieza y después se estudia el diseño con el método de elementos finitos y se modifica hasta alcanzar los requisitos necesarios. Finalmente se añaden elementos auxiliares necesarios y se realizan los planos de la pieza.

Hidrogenoaren ekoizpena hiri hondakin plastikoen pirolisi eta erreformatuaren bidez

Material plastikoen kontsumoak izugarri gora egin du azken mendean. Hori dela eta, material hauek erabiltzearen ondorioz sortutako hondakinak asko handitu dira. Europar Batasuneko herrialdeetan 250 milioi tona baino gehiago hiri - hondaki n solido ( RSU ) sortzen dira urtero, urteko %3ko hazkunt zarekin. K antitate honen %7a plastiko hondakinei dagokie, hots, 17.5 milioi tona. Itsasoko uretan ere aurki daitezke plastikoak, urtero sei milioi tona eta erdi botatzen baitira itsasora, mediterraneo itsasoa izanik munduko plastiko biltegirik handiena. Itsasoan 90 urteraino iraun dezake te eta urte hauetan zehar distantzia handiak egin ditzakete aldatu gabe. Horregatik esaten da plastikoak iraunkorrak direla. Egun, hondakin plastikoen portzentaia txiki bat bakarrik birziklatzen da eta bai biltegiratzea bai erreketa bidezko eliminazioak ingurumen arazoak dituzte . Gainera, plastiko gehienak degradaezi nak dira, urte luzez ingurugiro kalteak eraginez . Hori dela eta, material hauen balorizaziorako teknologia berrien sustapena beharrezkoa da, eskala handian eraginkorrak, ekonomikoki bideragarriak eta ingurugiroa errespetatuko dutenak. Hondakin plastikoetatik abiatuz hidrogenoa lortzeko prozesua interesgarria eta bideragarria da, hidrogenoaren kontsumoaren igoe ra kontuan hartuz. Gaur egun erregai fosilen prozesaketatik lortzen da hidrogenoa, CO 2 - a ren emisio handiak sortzen direlarik. Emisio hauen murrizketa beharrezkotzat hartu da. Hau guztiagatik, Gradu Amaierako Lan honen helburu nagusia plastikoen balorizazio a ikertzea da, konkretuki hiri - hondakin solidoetan aurkitzen diren plast ikoena . Pirolisi eta ur baporearen bidezko erreformatua erabili dira hidrogenoa lortzeko, azken hau balio handiko produktua izanik. Horretarako lehenengo etapa iturri ohantze konikoan, 500 ºC - tan, buruturiko pirolisia izan da eta bigarrenik ohantze fluidizatu batean ur baporearen bidezko erreformatua burutu da , 700 ºC - tan . Helburu nagusi hau betetzeko bestelako helburu zehatzak ezarri dira, hiri - hondakin solidoetan aurkitzen diren HDPE, PP, PS eta PET plastiko nahaste baten bideragarritasuna aztertu delarik aurrez aipatutako bi etapen bidez:  Plastiko nahastearen pirolisian sorturiko konposatu hegazkorren erreformatua era jarraian burutzea.  Zero denboran e rreakzio indizeak (konbertsioa et a etekinak) eta lortutako gasaren konposizioa determinatze a .  Erreformatuan erabilitako katalizatzailearen desaktibatzeak erreakzioa ren konbertsio eta etekina n duen eragina aztertzea.
