Implementation of a global P-recovery system in urban wastewater treatment plants
2019
[EN] Current wastewater treatment plants (WWTPs) paradigm is moving towards the so-called water resource recovery facilities in which sewage is considered a source of valuable resources. In particular, urban WWTPs are crucial systems to enhance phosphorus (P) recycling. This paper evaluates the implementation of a P-recovery system in Calahorra WWTP combining the operation of a new sludge line configuration coupled to a struvite crystallisation reactor at demonstration-scale. This new configuration consisted in the elutriation in the gravity thickener of the mixed sludge contained in the mixing chamber in order to reduce the phosphate load to the anaerobic digestion. The results indicated t…

2021
Raksts tapis sadarbībā ar LU Fonda stipendiāti Anniju Pozņaku, lai popularizētu LU vēsturi studentu vidē. Raksta centrā ir izcils sportists, leģendārs latviešu basketbolists, latviešu studentu korporācijas "Beveronija" loceklis Rūdolfs Jurciņš, kurš bija Latvijas Basketbola izlases kapteinis 1935. gada Eiropas pirmajā Basketbola čempionātā Ženēvā, Šveicē. Basketbola izlases kapteinis aizveda Latviju līdz pirmajam Eiropas Basketbola čempiona titulam, uzvarot Spāniju finālā. Abi autori analizē divus aspektus - Annija sporta, Rūdolfs korporatīvo aspektu.
“Sentir el cuerpo”: subjetividad y política en la sociedad de masas en España (1890-1931)
2018
El artículo reflexiona sobre las condiciones de aparición de los sujetos en la acción política asumiendo la centralidad del cuerpo como categoría de análisis. Partimos de la hipótesis de que el lenguaje de la política necesita un cuerpo en el que materializarse. Hay dos partes muy marcadas. En la primera, de carácter teórico, se repasan algunos hitos en la renovación del concepto de cuerpo y sus consecuencias en la conformación de la subjetividad. Se propone un concepto spinozista de cuerpo entendiendo este como espacio afectado en el que las emociones se materializan y, a la vez, como espacio activo en la producción del significado. En la segunda parte, se analiza un estudio de caso. La te…
Temporality of Maternity, Chronic Pain, and Ethics: Challenging Current Narratives on Pain and Health
2021
This chapter aims to articulate new ethical possibilities made apparent during experiences of chronic pain, and suggest an ethics of temporality apparent in the mother–child relation. I also aim to bring an understanding of the complexity and diversity of subjectivities in pain and its impact on its social, intersubjective environment. The narratives of mothers who have experienced chronic pain for more than three months help articulate a gap found in the Western model of medical knowledge. I hope to shift attention from the perspective of a patient understood as an objectified object of pain and from pain as a separate object of study to a study of the concrete embodied experiences of moth…
Plan d’action suffragiste en faveur de la cause féminine: femmes rédactrices, catalyseurs des réformes sociales et politiques dans l’Angleterre victo…
2019
National audience; La suppression du droit de timbre en 1855 et des taxes sur le papier en 1861, en Angleterre, favorise la création de plusieurs organes de presse dont le magazine féministe The Englishwoman’s Journal (1858-1864). Sa stratégie éditoriale consiste à promouvoir les analyses critiques des journalistes de sexe féminin contre les politiques conservatrices anglaises concernant la condition féminine. Les co-fondatrices du groupe de Langham Place, Barbara Leigh Smith (1827-1891) et Bessie Rayner Parkes (1829-1925), donnent la parole à la communauté féminine qui n’a de véritable possibilité d’expression et de communication que l’écriture. Se dégageant de toute restriction d’expressi…
Molecular Search of New Active Drugs AgainstToxoplasma Gondii
1999
Molecular connectivity has been applied to the search of new compounds with activity against the protozoan Toxoplasma gondii, using a stepwise linear discriminant analysis (SLDA) which is able to classify a compound according its activity either as active or as inactive. Among the selected compounds, andrographolide and dibenzotiophene sulfone stand out, both with IC50 values lower than 1 microgram/ml, which are comparable to these of drugs such as sulfamethoxazole, pyrimethamine and trimethoprim, with IC50 values equal to 1.1, 0.04 and 2.31 micrograms/ml, respectively. These results confirm the usefulness of our topological approach for the selection and design of new-lead drugs active aga…
Diode laser spectroscopy of the nu(8) band of the SF(5)Cl molecule.
2003
Abstract Diode laser spectra of SF 5 Cl have been recorded in the ν 8 band region at a temperature of ca. 240 K, a pressure of 0.25 mbar and an instrumental bandwidth of ca. 0.001 cm −1 . Four regions have been studied: a first one in the P -branch (906.849–907.687 cm −1 ), a second one in the Q -branch (910.407–910.944 cm −1 ), and two other ones in the R -branch (913.957–914.556 and 917.853–918.705 cm −1 ). The whole ν 1 / ν 8 dyad of SF 5 35 Cl has been previously recorded in the group of Professor H. Burger in Wuppertal, thanks to a Fourier transform infrared spectrometer [J. Mol. Spectrosc. 208 (2001) 169]. These data have thus been combined with our diode laser ones in the aim of refi…
Multiple band crossings and Fermi surface topology: Role of double nonsymmorphic symmetries in MnP-type crystal structures
2019
We use relativistic ab-initio methods combined with model Hamiltonian approaches to analyze the normal-phase electronic and structural properties of the recently discovered WP superconductor. Remarkably, the outcomes of such study can be employed to set fundamental connections among WP and the CrAs and MnP superconductors belonging to the same space group. One of the key features of the resulting electronic structure is represented by the occurrence of multiple band crossings along specific high symmetry lines of the Brilloiun zone. In particular, we demonstrate that the eight-fold band degeneracy obtained along the SR path at (kx,ky)=(Pi,Pi) is due to inversion-time reversal invariance and…
Spin–orbit coupling effects on the electronic properties of the pressure-induced superconductor CrAs
2019
We present the effects of spin-orbit coupling on the low-energy bands and Fermi surface of the recently discovered pressure-induced superconductor CrAs. We apply the L\"owdin down-folding procedure to a tight-binding hamiltonian that includes the intrinsic spin-orbit interaction, originating from the Cr 3d electrons as well as from As 4p ones. Our results indicate that As contributions have negligible effects, whereas the modifications to the band structure and the Fermi surface can be mainly ascribed to the Cr contribution. We show that the inclusion of the spin-orbit interaction allows for a selective removal of the band degeneracy due to the crystal symmetries, along specific high symmet…
Evidence for eight node mixed-symmetry superconductivity in a correlated organic metal
2015
We report a combined theoretical and experimental investigation of the superconducting state in the quasi-two-dimensional organic superconductor $\kappa$-(ET)$_2$Cu[N(CN)$_2$]Br. Applying spin-fluctuation theory to a low-energy material-specific Hamiltonian derived from ab initio density functional theory we calculate the quasiparticle density of states in the superconducting state. We find a distinct three-peak structure that results from a strongly anisotropic mixed-symmetry superconducting gap with eight nodes and twofold rotational symmetry. This theoretical prediction is supported by low-temperature scanning tunneling spectroscopy on in situ cleaved single crystals of $\kappa$-(ET)$_2$…
