Propiedades mecánicas y acústicas de hormigones con áridos reciclados y neumáticos fuera de uso
Industrial progress used to be linked to the produce of large waste volumes. These industrial by-products are deposited in landfills despite these ones could be used to manufacture others. In fact, the construction industry could incorporate these materials to contributing to greater environmental balance.
This paper studies the manufactured of concrete using as aggregates two kind of different wastes: construction and demolition wastes as well as recycled tires rubber (NFU). Natural fine fraction is replaced by a 10% by volume of industrial products analyzed. The mechanical behaviour and the acoustic properties of concrete made with recycled aggregates are studied. Results show a reduction in mechanical properties by using recycled aggregates and NFU. Nevertheless, it is observed that concrete made with fine recycled aggregate fraction of NFU could be employed with all the guarantees to produce concrete for non-structural applications.El progreso industrial lleva asociado la generación de grandes volúmenes de residuos que, en la mayoría de los casos, acaban en los vertederos, desperdiciando su potencial como materias primas para otros sectores industriales, como es el sector de la construcción, por lo que debe considerarse su reutilización en nuevas aplicaciones e incorporación como subproducto en el campo de los materiales de construcción, dando lugar a materiales más ecoeficientes y respetuosos con el medioambiente.
Este trabajo estudia el empleo de áridos reciclados procedentes de residuos de construcción y demolición, y caucho procedente de neumáticos fuera de uso (NFU) en la fabricación de hormigones. La fracción fina natural ha sido sustituida por un 10% en volumen de los subproductos industriales analizados. El comportamiento físico, mecánico y las propiedades acústicas de los hormigones ha sido comparado con los hormigones de referencia. En los resultados se observa una reducción de las resistencias mecánicas y del modulo de elasticidad por el empleo de áridos reciclados
y NFU. Se muestra que los hormigones fabricados con la fracción fina de áridos reciclados y NFU podrían ser empleados con todas las garantías en hormigones para aplicaciones no estructurales
What format of treatment do patients with emotional disorders prefer and why? Implications for public mental health settings and policies
Objective
We analyzed the preference of three psychological intervention formats—individual, group,
and online—in a sample of 267 patients with a primary diagnosis of emotional disorder in
Spanish public mental health settings.
Method
We studied patients’ preferences considering sociodemographic characteristics, diagnoses,
history of psychological treatments, number of sessions, and satisfaction with past
interventions.
Results
Most participants (85.4%) preferred psychological treatment in an individual format, 14.2%
in group, and 0.4% online. When comparing the people who chose individual and group
treatment, no demographic or clinical differences were found. The arguments against group
format were the lack of privacy and expression difficulties. Regarding online format, these
included being considered impersonal and ineffective.
Conclusion
The rejection of group and online psychotherapy formats allows us to define the actions we
should carry out in public mental health settings to improve the acceptance of more costeffective therapy formats
Efficacy of the unified protocol for the treatment of emotional disorders in the Spanish public mental health system using a group format: study protocol for a multicenter, randomized, non-inferiority controlled trial
Background:
Emotional disorders, which include both anxiety and depressive disorders, are the most prevalent
psychological disorders according to recent epidemiological studies. Consequently, public costs associated with their
treatment have become a matter of concern for public health systems, which face long waiting lists. Because of their
high prevalence in the population, finding an effective treatment for emotional disorders has become a key goal of
today
’
s clinical psychology. The Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders might serve
the aforementioned purpose, as it can be applied to a variety of disorders simultaneously and it can be
easily performed in a group format.
Methods:
The study is a multicenter, randomized, non-inferiority controlled clinical trial. Participants will be 220
individuals with emotional disorders, who are randomized to either a treatment as usual (individual cognitive
behavioral therapy) or to a Unified Protocol condition in group format. Depression, anxiety, and diagnostic criteria are
the primary outcome measures. Secondary measures include the assessment of positive and negative affect, anxiety
control, personality traits, overall adjustment, and quality of life. An analysis of treatment satisfaction is also conducted.
Assessment points include baseline, post-treatment, and three follow-ups at 3, 6, and 12 months. To control for missing
data and possible biases, intention-to-treat and per-protocol analyses will be performed.
Discussion:
This is the first randomized, controlled clinical trial to test the effectiveness of a transdiagnostic
intervention in a group format for the treatment of emotional disorders in public settings in Spain. Results obtained
from this study may have important clinical, social, and economic implications for public mental health settings in
Spain.

Cool pavements for climate change adaptation
Trabajo presentado en: R-Evolucionando el transporte, XIV Congreso de Ingeniería del Transporte (CIT 2021), realizado en modalidad online los días 6, 7 y 8 de julio de 2021, organizado por la Universidad de BurgosIn the framework of road infrastructures, CHM has led a study that investigates
construction products in order to combat the heat that is accumulated and released by urban
surfaces, such as asphalt, especially in summer, seeking to minimize the "island of urban
heat".
This project is the result of having developed reflective pavements (cool pavements) than
have passed through the first phase at the laboratory level, manufacturing on an industrial
scale and their small-scale testing to ensure proper implementation, as well as their
implementation by means of a large-scale demonstrator, operating on 24.000 m2 of
pavement in the city of Murcia (LIFE HEATLAND).
This mixture has a series of benefits with respect to conventional mixtures, leading to an
improvement in the urban environment and quality of life of the citizens of the
implantation environment and which are mainly:
- Saving energy in air conditioning and in the consumption of public lighting.
- Saving energy consumption and raw materials.
- Improves air quality.
- Improves noise pollution.
- Improves comfort and health of pedestrians.
- Economic and environmental benefits.
To date, the demonstrator has been monitored and the following conclusions have been
obtained, validating this type of pavement as a mechanism to reduce the urban heat island
effect:
- Initial luminance of reflective pavement 2.5 cd / m2 under the lamppost, 150%
higher than in the conventional asphalt street.
- Solar reflectance is almost four times higher than conventional asphalt.
- Average surface temperature for reflective pavement of 7-11 ºC lower than
conventional.
- Asphalted areas where tire rubber has been deposited as a result of the rolling of
vehicles are heated 1-3 ºC more than clean areas.
- Environmental noise level of the area: 3 dB (A) lower.Centro para el Desarrollo Tecnológico Industrial (CDTI). - Programme LIFE. - CHM Obras e Infraestructuras, S.A. - CTCON: Julio López, Gloria Motos, Francisco Moral, etc. - Ayuntamiento de Murcia. - XIV Congreso de Ingeniería del Transporte (CIT 2021)

Increasing size and abundance of microbialities (oncolds) in connection with the K/T boundary in non-marine environments in the South Central Pyrennees
A layer rich in giant microbialites, developed within continental deposits of the Tremp Formation (South-Central Pyrenees) in the aftermath of the end-Cretaceous mass extinctions, is here reported for the first time. Its stratigraphic location just above the Latest Maastrichtian Reptile Sandstone unit, and a characteristic 13C anomaly, are clear proofs linking this so-called �z� layer to the K/T boundary. The great abundance of microbialites, their outsized dimensions (oncoids with coating thickness up to 1.2m; average >50mm), and the great lateral continuity of the �z� layer in the study zone, support the hypothesis that these giant microbialites may represent disaster forms linked to the latest Mesozoic crisis. To our knowledge, this is the first time a record of this type is reported in continental realms. Other large continental oncoids and stromatolite constructions (e.g., in the Late Palaeogene deposits of the Pyrenees, Ebro basin, and Mallorca island) differ from those of the �z� layer in occurring in carbonate rocks and in having less lateral continuity, but they could also have been favoured by palaeoenvironmental crises, such as the global Eocene hyperthermals, Early Eocene Climatic Optimum, Middle Eocene Climatic Optimum, and the climatic cooling of the Eocene-Oligocene transition. It is thus possible that some layers of microbialites may record biotic crises in continental series, as they do in the marine record

Agricultura y clima : retorno a Hortaleza
Con este proyecto se quiere mostrar las implicaciones del clima en la agricultura y las actividades rurales del antiguo pueblo de Hortaleza. Los objetivos son promover actitudes de tolerancia y respeto a los demás, al medio ambiente y a las distintas formas de vida, mediante la convivencia y la participación en actividades en grupo; y conocer de forma directa el trabajo agrícola y meteorológico. Las actividades se centran en la Estación Meteorológica y el Huerto. Se realizan grupos pequeños de alumnos que preparan la tierra, buscan los productos idóneos, hacen semilleros, recolectan y consumen; miden datos meteorológicos cada mañana, observan las nubes, recopilan datos y elaboran gráficos. La evaluación, continua, se realiza a través de reuniones donde se analizan los diarios del alumno y las encuestas a padres y alumnos. Se valora la curiosidad despertada, las relaciones entre alumnos y profesores-alumnos y la consecución de rigor y método científico en la toma de datos y en la observación.Madrid (Comunidad Autónoma).
