20 p, 378.1 KB The Gendered Duality of Coldness in the Portrayals of Eliza Hayley / Blanch Serrat, Francesca (Universitat Autònoma de Barcelona)
In the eighteenth century, coldness was defined, on the one hand, in relation to the body and the senses (a body that is lacking in heat) and on the other, to emotion (an individual lacking in passion). [...]

47 p, 511.9 KB The inversion height of the free field is infinite / Herbera i Espinal, Dolors (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Sánchez, Javier (University of São Paulo. Department of Mathematics)
Let X be a finite set with at least two elements, and let k be any commutative field. We prove that the inversion height of the embedding k(X) D, where D denotes the universal (skew) field of fractions of the free algebra k(X), is infinite. [...]

50 p, 553.1 KB Relatively big projective modules and their applications to direct sum decompositions / Álvarez Arias, Román (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Herbera i Espinal, Dolors (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Prihoda, Pavel (Charles University. Department of Algebra)
Countably generated projective modules that are relatively big with respect to a trace ideal were introduced by Příhoda, as an extension of Bass' uniformly big projectives. It has already been proved that there are a number of interesting examples of rings whose countably generated projective modules are always relatively big. [...]

9 p, 252.2 KB A Family of Examples of Generalized Perfect Rings / Aydoğdu, Pınar (Hacettepe University. Department of Mathematics) ; Herbera i Espinal, Dolors (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We construct a family of semiprimitive and non von Neumann regular rings satisfying that any right or left module is isomorphic to a quotient of its flat cover (in the sense of Enochs) by a small submodule. [...]

14 p, 8.4 MB Full-scale co-composting of low-biodegradable digestate from the source-selected organic fraction of municipal solid waste with wood-derived biochar : Insights on process performance, gaseous emissions, and engineering implications / Olivera Begué, Elena (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; González Alé, Daniel (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental) ; Kaal, Joeri (Pyrolyscience) ; Camps-Arbestain, Marta (Shell Technology Centre Amsterdam) ; Sanchez, Antoni (Universitat Autònoma de Barcelona. Departament d'Enginyeria Química, Biològica i Ambiental)
A full-scale trial was performed to examine the effect of wood-derived biochar on the composting of digestate from the anaerobic digestion of source-selected organic fraction of municipal solid waste (OFMSW), compared with that of only OFMSW digestate. [...]

64 p, 702.3 KB Big pure projective modules over commutative noetherian rings : Comparison with the completion / Herbera i Espinal, Dolors (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Prihoda, Pavel (Charles University. Department of Algebra) ; Wiegand, Roger (University of Nebraska. Department of Mathematics)
A module over a ring R is pure projective provided it is isomorphic to a direct summand of a direct sum of finitely presented modules. We develop tools for the classification of pure projective modules over commutative noetherian rings. [...]

62 p, 628.7 KB Torsion-free modules over commutative domains of Krull dimension one / Álvarez Arias, Román (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Herbera i Espinal, Dolors (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Prihoda, Pavel (Charles University. Department of Algebra)
Let R be a domain of Krull dimension one. We study when the class F of modules over R that are arbitrary direct sums of finitely generated torsion-free modules is closed under direct summands. If R is local, we show that F is closed under direct summands if and only if any indecomposable, finitely generated, torsion-free module has local endomorphism ring. [...]

13 p, 2.1 MB Long-term comparison shows protected and non-protected forests differ in harvesting, but not in wildfires or drought-driven dieback / Espelta Morral, Josep Maria (Universitat Autònoma de Barcelona) ; Viana-Soto, Alba (Technical University of Munich) ; Molowny Horas, Roberto (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Cáceres Ainsa, Miquel de (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Selwyn, Miriam (Universitat Autònoma de Barcelona) ; Banqué Casanovas, Mireia (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Brotons, Lluís (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Lloret Maya, Francisco (Universitat Autònoma de Barcelona) ; Martínez Vilalta, Jordi 1975- (Universitat Autònoma de Barcelona) ; Piqué Nicolau, Míriam (Centre de Ciència i Tecnologia Forestal de Catalunya (CTFC)) ; Senf, Cornelius (Technical University of Munich)
While disturbances are essential for biodiversity, their escalation driven by climate change may threaten forest ecosystems. Contrasting approaches to adapt forests to disturbances-intensifying management versus encouraging natural succession towards more mature ecosystems-have sparked a debate about whether protection influences forests' vulnerability to disturbance.

36 p, 1.3 MB Arte, ciencia y planeamiento urbano : : de la utopía tecnológica moderna a la ciudad más que humana / Álvaro, Sandra (Universitat Autònoma de Barcelona. Departament d'Art i de Musicologia)
La expansión de las ciudades es otro de los factores que han dado lugar al desdevenir que denominamos Antropoceno. En el avance de la urbs la relación entre ciudadano, tecnología y naturaleza se ha articulado de diversos modos, desde considerar la naturaleza como modelo para el diseño racional del espacio habitado, en los primeros pensadores de la planificación urbana, al descubrimiento de la capacidad generativa de la diversidad en los años 70s y hasta la actual propuesta de una ciudad para la convivencia interespecífica. [...]
Urban expansion is an important factor leading to the unbecoming that we call Anthropo-cene. The urbanization has articulated the relationship between citizens, technology, and nature in different ways, from considering nature as a model for the rational design of the inhabited space by the first thinkers of urban planning, to the discovery of the generative capacity of diversity in the 1970s and the current proposal of an interspecific city.
