Volume and bond length dependences of the electronic structure of 6-fold and 8-fold coordinated Co2+ in pressure transformed CoF2

This work reports an optical absorption study on CoF2 under high-pressure conditions in the 0-80 GPa range. A recent structural study1 performed on the pressure-induced phase-transition sequence of CoF2 reveals that this compound undergoes a structural transformation associated with a change of Co2+ coordination from 6 (rutile type) to 8 (fluorite type) at 15 GPa, what implies a profound change in the Co2+ electronic ground state associated with the inversion of d orbitals from (t 2g 5 e g2) to (e g 4 t 2g 3). This allows us to explore the Co2+ electronic structure, and hence 10Dq, as a function of the density and the Co-F bond length in both CoF6 (rutile phase) and CoF8 (fluorite phase) coordinations. The results are compared with those obtained in KCoF3 (perovskite) in a wide range of Co-F distances (from 2.04 to 1.83 Å).Financial support from the Spanish Ministerio de Economía y Competitividad (Project No. MAT2015-69508-P) and MALTA INGENIO-CONSOLIDER 2010 (Ref.

Study by DTA/TG of the formation of calcium aluminate obtained from an aluminium hazardous waste

A Spanish hazardous waste from tertiary aluminium industry was used as a raw material for the synthesis of calcium aluminate. An amorphous precursor was obtained by a hydrothermal method at different values of pH. The transformation of the precursor in a crystalline aluminate was followed by TG/DTA up to 1300 C. At temperatures between 719 and 744 C, the precursors evolve towards the formation of C12A7 which becomes CA at circa 1016 C. Mass spectrometry coupled to thermal analyser allowed the identification of the decomposition productsMEC for financing project CTM2005-01964 and the company Recuperaciones y Reciclajes Roman S.L.

Cuatro altares de La Vera, Cáceres

This paper describes four Roman altars recently found in La Vera, which is the name given to the country lying between Tiétar river and Sierra de Gredos, in the Spanish province of Cáceres. Of the nine inscriptions, three epigraphs are dedications to local deities: Band(-) Vortiacius, a new divine couple, Ulisus and Ulisona; and Quangeius, this one being placed in fano, which is the second occurrence of that word in Spanish epigraphy. The last piece is a tombstone so dilapidated that it is difficult to tell apart even the normal features of an ancient epitaph.Se describen cuatro altares inscritos recientemente descubiertos en La Vera, comarca cacereña situada en la orilla septentrional del río Tiétar. De las nuevas inscripciones, tres son altares dedicados a lo que se han llamado “dioses indígenas”: Band(-) Vortiacius, lo que parece una nueva paredría (Ulisus y Ulisona) y Quangeius; nótese que este se colocó in fano, la segunda mención epigráfica del término aparecida hasta ahora en la Península. La última pieza es un epitafio, pero tan estropeado por la erosión, que apenas se reconocen los elementos característicos de esta clase de epígrafes

Descriptive and Quasi-Experimental Studies about Moral Emotions, Online Empathy, Anger Management, and Their Relations with Key Competencies in Primary Education.

BACKGROUND: Antisocial behaviours make social interactions difficult among students. Moral emotions, online empathy, and anger management are social and emotional variables related to prosocial and antisocial behaviours and health problems. This research aims to assess the impact of Cooperative Project-Based Learning intervention on these three variables for Primary Education students. Additionally, the relations of these variables with key competencies, such as social and emotional competencies and literacy competence, were studied. METHOD: This research is made up of two studies, descriptive and quasi-experimental, during regular school hours. The descriptive study was carried out with a sample of 516 primary school students and aimed to assess the development of the three variables, taking into account personal and ethnic-cultural factors. The quasi-experimental study, with pre-test and post-test data, had the participation of 145 students to study the incidence of these variables after Cooperative Project-Based Learning intervention in Primary Education. RESULTS: The results show the relation among the cited variables and the positive impact of the intervention on moral emotions and anger management in the experimental group compared to the control group. Experimental group girls presented higher scores in moral emotions than control group girls. CONCLUSION: These results open new research lines in relation to the intervention as a programme to prevent the appearance of antisocial behaviours and health problems at school

Seroprevalencia de las infecciones por el virus Diarrea Vírica Bovina en ganado bovino en Andalucía

Se ha realizado un estudio seroepidemiológico frente al virus de la Diarrea Vírica Bovina (vDVB) en la cabaña bovina andaluza, utilizando para ello un ELISA indirecto para la detección de anticuerpos frente a una proteína altamente conservada (p80). Después de eliminar los animales vacunados, la encuesta se realizó sobre 4.768 individuos pertenecientes a 227 colectivos no vacunados frente al vDVB, mediante muestreo estadístico para un nivel de confianza del 95 por ciento. La seropositividad obtenida ha sido del 42,3 por ciento de los individuos analizados, mientras que la prevalencia estimada de rebaños seropositivos alcanzó el 70,9 por ciento. La proporción de bovinos persistentemente infectados (IP) encontrada en la muestra (0,063 % de los individuos y 1,32 de los colectivos), ha sido más baja de la esperada en función de la alta seroprevalencia detectada, hecho que demuestra que la supervivencia de estos animales lógicamente está condicionada

Autologous Human-Derived Bone Marrow Cells Exposed to a Novel TGF-β1 Fusion Protein for the Treatment of Critically Sized Tibial Defect.

https://v2.sherpa.ac.uk/id/publication/12308We report the first clinical case of transplantation of autologous bone marrow-derived cells in vitro exposed to a novel recombinant human transforming growth factor (rhTGF)-β1 fusion protein bearing a collagen-binding domain (rhTGF-β1-F2), dexamethasone (DEX) and β-glycerophosphate (β-GP). When such culture-expanded cells were loaded into porous ceramic scaffolds and transplanted into the bone defect of a 69-year-old man, they differentiated into bone tissue. Marrow cells were obtained from the iliac crest and cultured in collagen gels impregnated with rhTGF-β1-F2. Cells were selected under serum-restricted conditions in rhTGF-β1-F2-containing medium for 10 days, expanded in 20% serum for 22 days and osteoinduced for 3 additional days in DEX/β-GP-supplemented medium. We found that the cell number harvested from rhTGF-β1-F2-treated cultures was significantly higher (2.3- to 3-fold) than that from untreated cultures. rhTGF-β1-F2 treatment also significantly increased alkaline phosphatase activity (2.2- to 5-fold) and osteocalcin synthesis, while calcium was only detected in rhTGF-β1-F2-treated cells. Eight weeks after transplantation, most of the scaffold pores were filled with bone and marrow tissue. When we tested the same human cells treated in vitro in a rat model using diffusion chambers, there was subsequent development of cartilage and bone following the subcutaneous transplantation of rhTGF-β1-F2-treated cells. This supports the suggestion that such cells were marrow-derived cells, with chondrogenic and osteogenic potential, whereas the untreated cells were not under the same conditions. The ability for differentiation into cartilage and bone tissues, combined with an extensive proliferation capacity, makes such a marrow-derived stem cell population valuable to induce bone regeneration at skeletal defect sites

Estudio del proceso de retención de 2,4-D en un carbón activo procedente de cáscara de almendra. II.-Isotermas de retención

Se han estudiado las isotermas de retención de 2,4-D, en disolución acuosa a las temperaturas de 10, 20, 30, 40 Y 50ºC, en un carbón activo preparado a partir de cáscara de almendra. Los datos obtenidos se han ajustado a las ecuaciones de Langmuir, B.E.T. y López-González, las cuales fueron adaptadas adecuadamente a procesos de adsorción en disolución. Se ha calculado la capacidad de retención del carbón activo utilizado, que es del orden de 10-3 moles de 2,4-D por gramo de carbón. Asúnismo, se han determinado la superficie del mismo accesible a las moléculas de 2,4-D, así como las magnitudes termodinámicas aparentes del proceso.Retention isotherms of 2,4-D in aqueous solution on an activated carbon at 10, 20, 30, 40 and 500C have been obtained.
