In questo saggio, vengono messe a confronto le recenti riflessioni di Habermas sul ruolo del rito nella storia umana con le teorie antropologiche di Girard
Shade effects on overseeded bermudagrass athletic fields: II. rooting, species composition, and traction
2019
Shade from athletic stadium structures can be a significant detriment to turfgrass performance. The objective of this study was to determine the effects of shade on rooting and playing surface stability, measured as traction, on overseeded or non-overseeded bermudagrass (Cynodon spp.) turf. An experiment was established in 2013 on a mature bermudagrass [Cynodon dactylon (L.) Pers. cv. Riviera] turf that was either overseeded with perennial ryegrass (Lolium perenne L.) or non-overseeded. Shade structures were installed to create four light level treatments, including 0%, 30%, 60%, or 90% light-reducing shade cloth. The light treatments resulted in average daily light integrals (DLI) of 40.8,…
Atomistic modeling of crystal structure of Ca1.67SiHx
2015
The atomic structure of calcium-silicate-hydrate (C-1.67-S-H-x) has been investigated by theoretical methods in order to establish a better insight into its structure. Three models for C-S-H all derived from tobermorite are proposed and a large number of structures were created within each model by making a random distribution of silica oligomers of different size within each structure. These structures were subjected to structural relaxation by geometry optimization and molecular dynamics steps. That resulted in a set of energies within each model. Despite an energy distribution between individual structures within each model, significant energy differences are observed between the three m…
Las Provincias
2012
El diario Las Provincias es el más antiguo de la Comunidad Valenciana (1866). A partir de la entrada en el accionariado del grupo Vocento (2000), y en torno al diario matriz, se ha ido creando paulatinamente un grupo multimedia (Las Provincias Multimedia) que cuenta con la versión web del medio, lasprovincias.es, y con varias licencias de radio asociadas bajo el nombre LP Punto Radio. Las Provincias también contó con una licencia autonómica de Televisión Digital Terrestre, Las Provincias Televisión, que acabó subsumida en la programación genérica de “La 10” (cadena de ámbito nacional de Vocento) y finalmente desapareció. Históricamente, Las Provincias siempre ha mantenido una dura pugna por…

The Structure, Stoichiometry and Properties of C-S-H Prepared by C3S Hydration Under Controlled Condition
1998
Hydrations of tricalcium silicate undertaken by keeping constant lime concentration in solution in an open system and in diluted suspensions for different values of [CaO] ranging between 6.5 and 30 mmol/1 show that the lime concentration in solution is the parameter which determines the main characteristics of the reaction and products. The stoichiometry of C3S hydration products vanes with lime concentration in the same way as synthetic C-S-H until C/S c.a. 1.5 corresponding to about [CaO] =20 mmol/1. Beyond this concentration, single phase C-S-H samples were obtained with 1.8<C/S<2. The discontinuity of the variation of stoichiometry with concentration is characteristic of an invariant po…

Calcium silicate hydrates: Solid and liquid phase composition
2015
© 2015 Elsevier Ltd. This paper presents a review on the relationship between the composition the structure and the solution in which calcium silicate hydrate (C S H) is equilibrated. The silica chain length in C S H increases with the silicon concentration and the calcium content in the interlayer space with the calcium concentrations. Sodium and potassium are taken up in the interlayer space preferentially at low calcium concentrations and thus by low Ca/Si C S H. Aluminium uptake in C S H increases strongly at higher aluminium concentrations in the solution. At low Ca/Si aluminium substitutes silica in the bridging position at Ca/Si. > 1 aluminium is bound in TAH. Recently developed ther…
