PBO Fibres: from saliling design towards architectural performance

p. 3013-3023PBO fibres, also called "high-performance" polymer fibres, are a group of materials known as "rigid rods". Through this work it is pretended to make some considerations about the use of these new generation fibres. Poly (p-phenylene-2.6-benzobisoxazole)(PBO) is rigid-rod isotropic crystal polymer. PBO fibre is a high performance fibre developed by TOYOBO (Japan) PBO fibre is quite flexible and has very soft handling, in spite of its extremely high mechanical properties. Over the past ten years Future Fibres Company has pioneered the use of PBO for yacht rigging and has proven it to provide remarkable performance and longevity. Their method of producing these PBO cables delivers the lightest, smallest cables available on the market today. The PBO cable is formed by combining the incredible properties of PBO (poly(p-phenylene-2,6- benzobisoxazole)) fibre with the simple yet undeniably reliable process of continuous winding. A PBO cable is dry fibre tightly compacted and does not rely on a resin matrix that, if impacted, can be compromised. The cover of the cable is a vital component and whilst PBO is an excellent material for yacht rigging purposes, due to its extreme strength, low elongation and general robustness it must be protected from sunlight and seawater. Future Fibres has perfected its cover design that comprises a consolidating film, environmental protection layer and a customizable braided cover that can be tailored to suit any specific application. PBO has great potential to be used in construction or rehabilitation applications. At the same time the fibres, following further testing, would open up several design opportunities for high quality architectural projects.Gough, CE.; Pobo Blasco, M.; Ruiz Checa, JR. (2009).

Decisions of refusal Intensive Care Units' admission as a measure of limitation of life support treatments: geographical variability in Spain

From a post hoc analysis of the ADENI-UCI study (multicenter, observational, cohort, prospective study, with a follow-up period of 13 months, in 62 Intensive Medicine Services in Spain. geographical differences in the reason for denial of income in UCI as a LTSV measure are analyzed. A total of 2284 with an average age of 75.25 (12.45) years were included. 59.43% male. By means of multinominal regression adjusted by age, sex, APACHE and SOFA, was evident (by choosing the northern for reference) that age in the south was a less significantly exposed reason (OR: 0.48 (IC95%: 0.35-0.65). p

Análisis comparativo de dos bases de bracket. Un estudio in vitro

El objetivo de este estudio ha sido evaluar las diferencias en la fuerza de adhesión entre dos brackets con bases diferentes: una base presenta la malla fina sin microarenar (bracket de American Orthodontics®) y el otro una malla profundamente ranurada y microarenada (bracket de Olmos®). Todos los brackets fueron soldados a barras de acero, se cementó en la base un composite fotopolimerizable (Eagle®) y se probaron para detectar el punto de fractura entre la base y el composite, mediante un esfuerzo de cizalla, en una máquina universal Instron. Se hallaron diferencias estadísticamente significativas entre ambos tipos de brackets. La malla rugosa (Olmos®) resultó tener una fuerza de adhesión bastante superior en comparación a la fina (American®)
