Life cycle assessment of the fluids used in a concentrated solar power plant

AIP conference proceedings (2018)

F.J. Pérez Esperanza Batuecas V. Encinas-Sánchez María Isabel Lasanta María Teresa de Miguel

In the present work, the environmental damage of two types of molten salts and synthetic oil has been evaluated with the aim of deciding whether the use of molten salts is more suitable than synthetic oil from an environmental point of view. To this end Life Cycle Assessment has been used, since it offers numerous advantages in the assessment of aspects associated with the development of a product and its potential impact throughout the life of a given product from raw material acquisition, processing, manufacturing, use and finally its disposal. According to the results, the replacement of the VP-1 like thermal oil by molten salts is absolutely recommended from an environmental perspective, since the environmental impact of molten salts appear to be reduced in comparison to Therminol®VP-1. Thus, direct systems, in which thermal storage and heat transfer fluid are unified using molten salts, emerge to improve the power cycle performance, these being a good option not only from the known technical point of view, but also from the environmental point of view. Life Cycle Assessment seems to be a suitable and necessary methodology to quantify the environmental impacts of fluids, materials, and O&M in CSP plants.

Conocimientos, actitudes y prácticas sobre la enfermedad de Chagas en población escolar de una zona endémica del Perú

Cadernos de Saúde Pública (2003)

Rufino Cabrera C. Mayo Nicolas A. Suarez César Infante César Náquira

El objetivo del estudio es presentar los resultados obtenidos sobre conocimientos, actitudes y prácticas acerca de la enfermedad de Chagas, en 241 escolares de educación primaria en La Tinguiña, Ica, Perú (diciembre 2000 - enero 2001). Menos del 1% de los encuestados reconoce que los triatomas trasmiten la enfermedad de Chagas, y casi la cuarta parte reconoce la enfermedad por la formación de "ronchas" en la piel; el 35,27% sabe que la infestación por el vector se controla con insecticidas. El 26,56% reconoce a los estados adultos del vector y el 21,16% a las ninfas; el 14,11% lo conoce con el nombre de "chirimacha"; el 82,57% aceptaría una encuesta entomológica; el 66,80% permitiría un estudio serológico y el 63,90% participaría en la búsqueda de triatominos. Este estudio revela que la población, a pesar de tener conocimientos muy limitados sobre la enfermedad y su vector, muestra interés en colaborar. Por lo tanto, se recomienda que las estrategias de vigilancia y control de esta enfermedad, incluyan necesariamente programas educativos y de participación comunitaria, en la implantación de futuros programas de control.

Peripatric speciation in an endemic Macaronesian plant after recent divergence from a widespread relative

PLoS ONE (2017)

Francisco J. Valtueña Tomás Rodríguez‐Riaño Josefa López C. Mayo Ana Ortega‐Olivencia

The Macaronesian Scrophularia lowei is hypothesized to have arisen from the widespread S. arguta on the basis of several phylogenetic studies of the genus, but sampling has been limited. Although these two annual species are morphologically distinct, the origin of S. lowei is unclear because genetic studies focused on this Macaronesian species are lacking. We studied 5 S. lowei and 25 S. arguta populations to determine the relationship of both species and to infer the geographical origin of S. lowei. The timing of S. lowei divergence and differentiation was inferred by dating analysis of the ITS region. A phylogenetic analysis of two nuclear (ITS and ETS) and two chloroplast (psbJ-petA and psbA-trnH) DNA regions was performed to study the relationship between the two species, and genetic differentiation was analysed by AMOVA. Haplotype network construction and Bayesian phylogeographic analysis were conducted using chloroplast DNA regions and a spatial clustering analysis was carried out on a combined dataset of all studied regions. Our results indicate that both species constitute a well-supported clade that diverged in the Miocene and differentiated in the Late Miocene-Pleistocene. Although S. lowei constitutes a well-supported clade according to nDNA, cpDNA revealed a close relationship between S. lowei and western Canarian S. arguta, a finding supported by the spatial clustering analysis. Both species have strong population structure, with most genetic variability explained by inter-population differences. Our study therefore supports a recent peripatric speciation of S. lowei-a taxon that differs morphologically and genetically at the nDNA level from its closest relative, S. arguta, but not according to cpDNA, from the closest Macaronesian populations of that species. In addition, a recent dispersal of S. arguta to Madeira from Canary Islands or Selvagens Islands and a rapid morphological differentiation after the colonization to generate S. lowei is the most likely hypothesis to explain the origin of the last taxon.

Effects of different abiotic and biotic factors on spatial primary seed dispersal in the semachorous species Scrophularia canina

Plant Species Biology (2019)

Tomás Rodríguez‐Riaño José Luis Pérez‐Bote Josefa López C. Mayo Francisco J. Valtueña

Abstract Seed dispersal is one of the most important steps in the plant life cycle. However, there is, generally, a lack of fieldworks focused on wind dispersal and especially on semachorous dispersal (seeds spread when the fruits are shaken by wind and other vectors, such as animals), including boleochorous dispersal. Therefore, we aimed to determine how different types of wind and animals affected seed dispersal under natural conditions in the widespread species Scrophularia canina . We evaluated the effects of wind gusts (simulating them using a leaf blower) and wild animals (using differently sized dogs) on seed dispersal in a population located in south‐western Europe. We found that S. canina is a semachorous species, and its spatial seed dispersal was affected by wind gust speed and direction, plant structure and vector type. The results also revealed the presence of xerochasy, individual anisotropy with strong winds, and primary short‐distance dispersal associated with successional processes independent of the vector. Additionally, there was a masking effect of plant structure on the seed shadow outline. It is essential to conduct fieldworks to reveal what actually happens in nature, taking into account the characteristics determining seed dispersal. In addition, in these works it is important to find out what factors affect seed distributions of anemochorous and semachorous species.
