Cost competitiveness of a novel PVT-based solar combined heating and power system: Influence of economic parameters and financial incentives
No full textThe cost competitiveness of an optimised solar combined heating and power (S-CHP) system based on a novel PVT collector is assessed in three different locations (Zaragoza, London and Athens). A series of sensitivity analyses are undertaken to evaluate the extent of the influence of the several economic parameters on the cost competitiveness of the proposed solar solution, and evaluate the need for financial incentives to boost the installation of this technology, in particular in the residential sector. From the different systems components’ costs, the results show that the PVT collector price is the one that influences more the system economics, as it responsible of the highest share of the total investment (~38%). High market discount rates and/or low inflation rates significantly and negatively affect the system cost competitiveness, leading to higher payback times (PBTs). Government incentives, if correctly applied, have the potential to improve the system economics in the short-term. However, in low latitude locations these incentives might not be necessary as high irradiance levels and energy prices lead to reasonable PBTs. Finally, the analysis of potential future scenarios, considering a combination of several economic parameters, demonstrates that the S–CHP system cost competitiveness is feasible in the short termPeer ReviewedPostprint (author's final draft

A comprehensive assessment of new absorber-exchanger designs for hybrid PVT-water collectors
No full textIn this paper, 26 alternative absorber-exchanger designs for hybrid PV-Thermal (PVT) solar collectors are proposed and compared against a reference-case, commercial sheet-and-tube PVT collector. The collectors involve different geometric design features based on the conventional sheet-and-tube configuration, and also on a newer flat-box structure constructed from alternative polymeric materials with the aim of maintaining or even improving heat transfer and overall (thermal and electrical) performance while achieving reductions in the overall weight and cost of the collectors. The main contributions of this research include: (i) the development and validation of a detailed 3-D computational finite-element model of the proposed PVT collector designs involving multi-physics processes (heat transfer, fluid dynamics and solid mechanics); (ii) results from comparative techno-economic analyses of the proposed PVT designs; and, (iii) further insights from thermal stress and structural deformation analyses of the proposed collectors, which are crucial for ensuring long lifetimes and especially important in the case of polymeric collectors. The results show that, in general, the flat-box designs (characterised by a thin absorber plate) are not sensitive to the flow-channel size or construction material, at least within the range of investigation. A PVT collector featuring a polycarbonate (PC) flat-box design with 3¿×¿2¿mm rectangular channels appears to be a particularly promising alternative to commercial PVT collectors, achieving a slightly improved thermal performance compared to the reference case (with a 4% higher optical efficiency and 15% lower linear heat-loss coefficient), while also lowering the weight (by around 9%) and investment cost (by about 21%) of the collector. The structural analysis shows that the maximum von Mises stress experienced in the absorber-exchanger of the PC flat-box collector is considerably lower than that in the copper sheet-and-tube collector (<13% vs. 64% of the material’s yield stress), which is attributed to the larger thermal expansion of the PC absorber-exchanger, that leads to lower stresses. Therefore, the proposed PC flat-box design is not expected to suffer higher strains than the commercially-available PVT collector.Peer Reviewe

Restoration of 19th Century oil on canvas.Portrait of magistrate joseph bernard falquet (1776 – 1836) by the french painter jacques guille (1814 – 1873) .
No full text[ES] Este Trabajo de Fin de Grado en Conservación y Restauración de Bienes Culturales (Universidad Politécnica de Valencia, España) se centra en un retrato al óleo sobre lienzo de la Francia del siglo XIX. El proyecto se ha realizado gracias a una estancia de prácticas en la empresa australiana Artlab, en dos fases de trabajo: (1) una investigación sistemática sobre la procedencia del retrato, y (2) y la concepción e implementación de un protocolo de restauración de la obra.
La pintura carecía de firma, y presentaba una nota escrita a mano, en el reverso del bastidor, que indicaba que el retrato representaba a un varón adulto de la familia Falquet de la localidad francesa de Chambery (Saboya, Francia). En base a la literatura primaria y comunicaciones con expertos, se llegó a la conclusión de que el teatro fue creado por Jacques Guille (artista francés especializado en pintura religiosa), y el hombre retratado era el Barón Joseph Bernard Falquet (magistrado que ocupó importantes cargos institucionales en la región de Saboya en tiempos posteriores a Napoleón). El estilo del retrato se encuadra dentro de la corriente neoclásica.
En general, la obra se encontraba en mal estado de conservación. El soporte textil presentaba un desgarro en la esquina inferior izquierda, se localizaron pérdidas de estrato pictórico en los bordes, y la superficie pintada estaba cubierta de suciedad superficial. Además, se identificaron zonas con abundante repinte como resultado de una intervención previa que había rellenado con estuco varios agujeros en el textil del lienzo.
La obra fue analizada mediante fotografía y reflectografía, y la intervención adoptó los protocolos establecidos por Artlab con los principales objetivos de realzar la estabilidad de la obra con un nuevo bastidor, restablecer la integridad del soporte textil, eliminar los parches de la vieja restauración, restaurar los estratos pictóricos y dotar a la pintura de protección para preservarla en el futuro.
La ejecución del proyecto se enriqueció por la interacción con procedimientos modernos de restauración dentro de un equipo profesional, y porque pudo contrastarse la formación teórica adquirida durante la licenciatura con la práctica de completar de principio a fin la restauración de una obra de arte.[EN] This Final-Year Project of the Bachelor¿s Degree in Conservation and Restoration of Cultural Heritage (University of Valencia, Spain) focuses on an easel oil-on-canvas portrait from 19th Century France. The project has been undertaken through an internship with ArtLab Australia, and consists of (1) a research component to identify the provenance of the portrait, and (2) a technical component to elaborate and implement a protocol of restoration.
The painting lacked author signature, and had a hand-written annotation on the backside of the stretcher indicating that the painted character was an adult male with the surname Falquet from the town of Chambery (Savoy, France). Based on a review of the primary literature and personal communications with international experts, it was concluded that the portrait was painted by Jacques Guille (a French artist who specialized in religious paintings), and the portrayed man was Baron Joseph Bernard Falquet (a French magistrate who played important institutional roles in post-Napoleon Savoy). The style of the portrait falls in the range of neoclassicism and realism.
Overall, the portrait was in poor condition. The canvas had a tear in the lower-left corner and had lost paint layers mostly along its edges, and the pictorial surface was entirely covered with superficial dirt. Repainted areas from a previous intervention were found over a stucco that filled several holes in the fabric of the canvas.
The restoration protocol applied to the portrait was based on photographic and reflectographic analyses and followed Artlab¿s canonical procedures with the major goals of enhancing structural stability with a new stretcher, re-establishing canvas integrity, removing old-restoration patches, restoring the paint layers and providing protection for long-term preservation.
Throughout, the project benefited from the exposure to the modus operandi of a professional team and from contrasting the theoretical fundaments provided by a Bachelor¿s Degree with the true process of restoration of a piece of art.José Herrando, C.

Hereditary Cancer Program (ProCanHe): 21-years of experience at a referral registry in Argentina
No full textRegistries in South America were initiated in the early 90´s with thehelp of Henry T. Lynch. The Programa de Cancer Hereditario (Pro.Can.He), is a multidisciplinary program established in 1996 at theHospital Italiano, Argentina. The aim of the study is to update our 21-year experience to determine the applicability of genetic testshighlighting the most informative molecular findings in relation toLynch syndrome mostly.Materials and methods: Families undergoing genetic testing aftergenetic counselling between1996-2018 were included. Data were obtainedfrom a prospective IRB approved database. Clinicalepidemiologicaland molecular variables were analysed. Genetic testswere carried out after a genetic counselling session and obtainingthe informed consent of the patient.Molecular testingUntil 2015, the search for variants was carried out by PCR and Sangersequencing of exons and adjacent intronic regions of MLH1 andMSH2. Then, sequencing of MLH1/MSH2/MSH6/PMS2/EPCAM geneswas performed by NGS and large rearrangements were detected byMLPA. The variants were classified according to international databases.Variants with uncertain or unreported clinical significancewere analysed In-silico using the PolyPhen, SIFT and/or Human Splicingfinder 3.0 software.ResultsA total of 83 families (49 fulfilled Amsterdam Criteria [AC] and 34 BethesdaCriteria [BC]) were analysed. Pathogenic variants were foundin 26 out of 83 (31.3%) families, been 23 pathogenic and 3 likelypathogenic.Splice site and large rearrangements represented 19.2% (5/26) and11.5% (3/26) of the variants.23% (6/26) of them were originally describedin this series and 1 was a founding mutation from Piedmont,Italy. Affected genes include MSH2, MLH1, MSH6 and PMS2 (12, 11, 2and 1 cases respectively). Mutation detection rates in AC and BT familieswere 48.9% (N=24) and 5.9% (N=2), p<0.01. Among AC families,those with identified mutation had a lower median age of cancer onset and higher incidence of extra-CCR cancer than those withoutidentified mutations. Additionally, we have also studied other genesin patients with different clinical conditions included in the registry.We identified mutations in APC, MUTYH, BMPR1A, SMAD4, CDH1,BRCA1-2, CHEK2.ConclusionThe multidisciplinary approach and the international collaborationsallowed the correct implementation of the genetic tests. To ourknowledge, this study is the first Characterization of AC families accordingto genetic tests in South America. This allowed the identificationof AC families with different ages of onset and prevalence ofextra-CRC cancers, as well as several significant variant not previouslyreported in international databases.Fil: Piñero, Tamara Alejandra.
