Composite Solutions for Construction Sector

FRP composite materials have been successfully used for several decades in the aerospace industry, while their use in Civil Engineering is relatively recent and generally in the form of sheets and strips employed to strengthen existing reinforced concrete structures. Since the construction of the first all‐FRP‐composite bridge in 1982, in Miyun, China, FRP composites have been gradually gaining acceptance as a new construction material for bridges and footbridges with some notable applications in Spain. Their use offers a number of advantages with respect to traditional materials:Since FRP composite members are lighter than those built using concrete and steel, they need less powerful equipment for their transport and installation;Their lightweight fosters prefabrication, speeding up construction processes, thus helping in the reduction of the impact of worksites on their surrounding areas;FRP composites can curb maintenance cost of infrastructures since they do not suffer from galvanic corrosion

Predicción de la reincidencia delictiva en menores infractores

XVI Congreso INFADI Internacional Congreso ICARO de temática: "Psicología y Sociedad en el siglo XXI. Competencias Relacionales"The criminal recidivism is one of the main worries of our society and its prediction is an important need in the research field, mainly in minors (Andrews & Bonta, 2006). This study tries to analyse the internal consistency of the IGI-J questionnaire (Garrido et al., 2003), used by the psychologists and social workers of the Juvenile Court in Castellón. This study tries to determine the risk of recidivism of each young offender as well as the percentage of correct classification, assessing the questionnaire accuracy. In order to achieve this goal, 210 young offenders that have committed any kind of crime, were selected for the questionnaire. A follow up study of six months was carried out to assess the recidivism through their files, focusing in the ones who recidivate. Results showed good internal consistency of the scales, as well as a good percentage of accurate classification in predicting future criminal conduct.La reincidencia delictiva es una de las grandes preocupaciones de nuestra sociedad y la predicción de ésta, sobre todo en menores, conlleva una clara utilidad (Andrews y Bonta, 2006). Este estudio pretende analizar la consistencia interna del cuestionario IGI-J Inventario de Gestión e Intervención para jóvenes (Garrido et al., 2003), utilizado por el Equipo Técnico del Juzgado de Menores de Castellón, para determinar el riesgo de cada menor de reincidir, así como el porcentaje de clasificaciones correctas que predice el cuestionario, valorando su eficacia. Para ello, se han seleccionado 210 menores acusados de cometer algún tipo de delito o falta en Castellón, a los que se administró el citado cuestionario. Para valorar la reincidencia se realizó un seguimiento de los expedientes de los menores, durante un periodo de 6 meses, diferenciando a los menores que reincidían de los que no. Los resultados mostraron una buena consistencia interna de las escalas, así como un buen porcentaje de clasificación correcta de los casos en la predicción de la reincidencia del cuestionario

Consensus document for the detection and management of chronic kidney disease.

Chronic kidney disease (CKD) is a major public health problem that, in its different stages, may affect up to 10% of the Spanish population and results in high morbidity and mortality, as well as high consumption of National Health System resources. Ten scientific societies involved in the management of kidney patients agreed to update the 2007 CKD consensus document. The current version is an abridged edition of the detailed general document, which can be consulted on the webpages of each signatory society. It includes the following aspects: CKD definition, epidemiology and risk factors and criteria on diagnosis, assessment and staging of CKD, albuminuria and glomerular filtration estimation. Progression factors and concept. Criteria for referral to Nephrology. Patient follow-up, attitudes and objectives by specialty. Prevention of nephrotoxicity. Detection of cardiovascular damage. Attitudes, lifestyle and treatment: management of high blood pressure, dyslipidaemia, hyperglycaemia, smoking, obesity, hyperuricaemia, anaemia and mineral and bone metabolism disorders. Coordinated follow-up by Primary Care - other specialties - Nephrology. Management of renal replacement therapy, haemodialysis, peritoneal dialysis and renal transplantation patients. Palliative treatment of terminal uraemia. We hope that this document will be very useful in the multidisciplinary management of CKD patients, in view of the updated recommendations

Association of Candidate Gene Polymorphisms With Chronic Kidney Disease: Results of a Case-Control Analysis in the Nefrona Cohort

Chronic kidney disease (CKD) is a major risk factor for end-stage renal disease, cardiovascular disease and premature death. Despite classical clinical risk factors for CKD and some genetic risk factors have been identified, the residual risk observed in prediction models is still high. Therefore, new risk factors need to be identified in order to better predict the risk of CKD in the population. Here, we analyzed the genetic association of 79 SNPs of proteins associated with mineral metabolism disturbances with CKD in a cohort that includes 2, 445 CKD cases and 559 controls. Genotyping was performed with matrix assisted laser desorption ionizationtime of flight mass spectrometry. We used logistic regression models considering different genetic inheritance models to assess the association of the SNPs with the prevalence of CKD, adjusting for known risk factors. Eight SNPs (rs1126616, rs35068180, rs2238135, rs1800247, rs385564, rs4236, rs2248359, and rs1564858) were associated with CKD even after adjusting by sex, age and race. A model containing five of these SNPs (rs1126616, rs35068180, rs1800247, rs4236, and rs2248359), diabetes and hypertension showed better performance than models considering only clinical risk factors, significantly increasing the area under the curve of the model without polymorphisms. Furthermore, one of the SNPs (the rs2248359) showed an interaction with hypertension, being the risk genotype affecting only hypertensive patients. We conclude that 5 SNPs related to proteins implicated in mineral metabolism disturbances (Osteopontin, osteocalcin, matrix gla protein, matrix metalloprotease 3 and 24 hydroxylase) are associated to an increased risk of suffering CKD

Canagliflozin and renal outcomes in type 2 diabetes and nephropathy

BACKGROUND Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium–glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to <90 ml per minute per 1.73 m2 of body-surface area and albuminuria (ratio of albumin [mg] to creatinine [g], >300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P=0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P<0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P=0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P=0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years

Estudi històric artístic i proposta de conservació del manuscrit Aureum Opus de la ciutat d'Alzira (València)

[ES] El siguiente Trabajo de Fin de Grado se centra en el estudio de las miniaturas que se integran en el Aureum Opus o Libro de Privilegios del Archivo Municipal de Alzira. Se trata de un códice que presenta dos partes claramente diferenciadas. Por una parte, el manuscrito del siglo XIV, en el que se localizan 6 folios con decoración miniada y, una segunda parte, con la recopilación de documentos de archivo hasta el siglo XIX. El actual estudio se centra en la parte medieval que recoge una serie de concesiones que los monarcas de la Corona de Aragón desde Jaime I hasta Pedro IV el Ceremonioso, otorgaron al Reino de Valencia. Para ello este estudio expone la documentación de la obra, así como su estudio material y técnico. Así mismo, y a partir de la documentación consultada se plantea una posible hipótesis acerca de los pigmentos utilizados en la elaboración de las miniaturas que presentan, distinguiendo la técnica utilizada para la escritura de los textos, de la empleada en las miniaturas que adornan las diferentes páginas. El estudio técnico y material se completa con un pormenorizado estudio del estado de conservación y de las condiciones de almacenamiento en las que se encuentra actualmente la obra. Todo ello ha permitido poner en valor la obra y establecer una serie de recomendaciones para su conservación y estabilidad a largo plazo.[EN] The following BA Project focuses on the study of the miniatures present in Aureum Opus or Book of Privileges of the Municipal Archive of Alzira. Aureum Opus is a codex that presents two clearly differentiated parts. On the one hand, the manuscript of the 14th century, in which six pages with illumination can be found and, a second part, with the collection of archival documents until the 19th century. The present study focuses on the medieval part that collects a series of concessions that the monarchs of the Crown of Aragon -from James I to Peter IV the Ceremonious-, granted to the Kingdom of Valencia. For this purpose, this study is aimed to document the book and to gain an insight into the materials and techniques used in it¿s manufacture. Likewise, after a literature search, a possible hypothesis about the pigments used in the elaboration of the miniatures is presented, distinguishing the technique used in the texts, from the one used in the miniatures in the different pages. The technical and material study is completed with a detailed study of the state of conservation and storage conditions in which the work is currently found. All this has made it possible to enhance the value of the work and to establish a series of recommendations for its long-term preservation and stability.Górriz Guillén, AP. (2022).
