No full textEntrevista a María del Mar Lozano Bartolozzi, por Moisés Bazán de HuertaEntrevista a María del Mar Lozano Bartolozzi.
Me reúno con María del Mar en Cáceres tras un tiempo de separación obligada por la pandemia que nos asola. A lo largo de muchos años hemos compartido en la Universidad de Extremadura Departamento, Grupo de Investigación, labores de gestión, proyectos de trabajo, publicaciones… La sintonía en estas lides ha marcado nuestra relación, pero la misma va más allá del ámbito académico, pues con ella y su familia me unen estrechos lazos de amistad. Por ello asumo con satisfacción esta oportunidad para entrevistarla…Interview with María del Mar Lozano Bartolozzi.
I meet María del Mar in Cáceres after a time of forced separation due to the pandemic that is ravaging us. For many years we have shared a Department, a Research Group, management tasks, work projects, publications... Our relationship has been marked by our harmony in these areas, but it goes beyond the academic sphere, as I have close ties of friendship with her and her family. That is why I am pleased to take this opportunity to interview her...peerReviewe
Radiofrequency ablation of lung tumours
No full textPulmonary radiofrequency ablation (RFA) has become an increasingly adopted treatment option for primary and metastatic lung tumours. It is mainly performed in patients with unresectable or medically inoperable lung neoplasms. The immediate technical success rate is over 95%, with a low periprocedural mortality rate and 8-12% major complication rate. Pneumothorax represents the most frequent complication, but requires a chest tube drain in less than 10% of cases. Sustained complete tumour response has been reported in 85-90% of target lesions. Lesion size represents the most important risk factor for local recurrence. Survival data are still scarce, but initial results are very promising. In patients with stage I non-small-cell lung cancer, 1- and 2-year survival rates are within the ranges of 78-95% and 57-84%, respectively, with corresponding cancer-specific survival rates of 92% and 73%. In selected cases, the combination of RFA and radiotherapy could improve these results. In patients with colorectal lung metastasis, initial studies have reported survival data that compare favourably with the results of metastasectomy, with up to a 45% 5-year survival rate. Further studies are needed to understand the potential role of RFA as a palliative treatment in more advanced disease and the possible combination of RFA with other treatment options

Comparison between hydrogen and electric vehicles by life cycle assessment: A case study in Tuscany, Italy
No full textThe use of hydrogen produced from renewable energy sources is often reported as an attractive strategy to address the issue of urban environmental sustainability in automotive sector, and a potential alternative to fossil fuel-fed vehicles. The project ‘Filiera Idrogeno’ (Hydrogen Chain) has investigated the potential realisation of hydrogen production chains from renewables and its use as automotive fuel in Tuscany Region (Italy). In this context, life cycle assessment was used for evaluating the environmental sustainability of such chains, applied to a fleet of hydrogen vehicles for urban commercial delivery.
From the energy supply side, renewable wind and biomass energy sources were considered for hydrogen production either by electrolysis or direct separation from biomass gasification syngas, according to specific simulations. Benchmarking with hydrogen produced by using Italian electricity mix was carried out. From the transport side, vehicles equipped with either fuel cell or internal combustion engine were evaluated.
A benchmarking analysis with standard electric vehicles supplied with electricity produced from the same renewable energy sources was also carried out.
The results give some indications on the environmental aspects of the different alternatives and on the contribution of the chain phases to the overall impacts

No full textThe environmental impact assessment of Asphalt Rubber: Life Cycle Assessment
No full textMaterial and energy recovery from end of life tires are the two alternatives to accomplish the European legislation, which has progressively banned landfill disposal with EC Directive 1999/31/EC. Therefore, diversified solutions for end of life tires management should be available to provide a concrete way for reuse and to help to solve the problem of the huge amount of old tires to be treated yearly. Among the material recovery alternatives, road construction using crumb rubber modified binders, called Asphalt Rubber, is already world widely used and is considered an excellent solution to recycle old tires.
In order to support a policy disclosure to this recycled material, the evaluation of the environmental impacts connected to the life cycle of the asphalt rubber is essential and Life Cycle Assessment is a holistic tool which allows for the evaluation of the overall impacts of the road life cycle and of its critical spots.
In this paper, the life cycle assessment of a specific case study of a crumb rubber modified asphalt mixture prepared with the wet method, near Florence (Italy) was evaluated.
The results of the study clearly identify the main contributing steps to the environmental impacts in the life cycle of the rubber asphalt road and therefore, together with the technical and economical evaluation of this technology, will be useful for policy makers when setting the reference specifications in public tenders.Material and energy recovery from end of life tires are the two alternatives to accomplish the European legislation, which has progressively banned landfill disposal with EC Directive 1999/31/EC.

Un Quijote de madera para el público infantil español: Pinocho Emperador de Salvador Bartolozzi (1917)
No full textThis paper aims to review the way in which the story written and illustrated by Salvador Bartolozzi titled Pinocho Emperador (1917) represents a recreation or reproduction of some passages from the famous Cervantes’ Don Quixote. Firstly, we will analyze the original work of the italian Carlo Collodi, Le avventure de Pinocchio, which was published at the end of the nineteenth century and had an impact on children's literature at that time. Then, through the analysis of the intertextuality between the character of the wooden puppet and the novel Don Quixote, we will show the influences of Cervantes’ text in Pinocho Emperador by Bartolozzi. This author takes up commonly known passages such as Don Quixote’s love of reading, his trip in search of adventure or his fight against the windmills, to offer his own version of this Spanish literature’s materpiece targeted mainly at children's audience.El presente trabajo pretende revisar el modo en el que el cuento escrito e ilustrado por Salvador Bartolozzi de título Pinocho Emperador (1917) supone una recreación o repropuesta de algunos pasajes de la célebre novela cervantina Don Quijote. En primer lugar, analizaremos la obra original, Le avventure de Pinocchio del italiano Carlo Collodi, aparecida a finales del siglo XIX y que supuso un impacto en la literatura infantil de la época. A partir de ahí, y con un análisis de la intertextualidad entre el personaje del títere de madera y la novela Don Quijote, pasaremos a evidenciar las huellas del texto cervantino en Pinocho Emperador de Bartolozzi. Este autor retoma pasajes comúnmente conocidos como la afición del Quijote por la lectura, su salida a la busca de aventuras o su lucha contra los molinos, para ofrecer una versión propia del clásico de la literatura española dedicado al público eminentemente infantil
