Energy and environmental impact of an anaerobic membrane bioreactor (AnMBR) demonstration plant treating urban wastewater
2020
Abstract In order to assess the environmental feasibility of anaerobic membrane bioreactor (AnMBR) technology for urban wastewater (UWW) treatment at ambient temperature, a demonstration plant was operated within the LIFE MEMORY project ( http://www.life-memory.eu/en/ ). This plant incorporates full-scale hollow-fiber membrane modules and was fed with the effluent from the pre-treatment of the “Alcazar de San Juan” WWTP (Alcazar de San Juan, Ciudad Real, Spain). Because of the dimensions of this plant, the system can be regarded as a previous step to the scale-up of AnMBR technology for full-scale UWW treatment. High-energy recovery potentials were achieved treating medium-/high-loaded UWW …
Towards a converged barrier height for the entrance channel transition state of the N(2D)+CH4 reaction and its implication for the chemistry in Titan…
2011
Abstract The N( 2 D) + CH 4 reaction appears to be a key reaction for the chemistry of Titan’s atmosphere, opening the door to nitrile formation as recently observed by the Cassini–Huygens mission. Faced to the controversy concerning the existence or not of a potential barrier for this reaction, we have carried out accurate ab initio calculations by means of multi-state multi-reference configuration interaction (MS-MR-SDCI) method. These calculations have been partially corrected for the size-consistency errors (SCE) by Davidson, Pople or AQCC corrections. We suggest a barrier height of 3.86 ± 0.84 kJ/mol, including ZPE, for the entrance transition state, in good agreement with the experime…
Excited State N−H Tautomer Selectivity in the Singlet Energy Transfer of a Zinc(II)-Porphyrin-Truxene-Corrole Assembly
2017
International audience; An original corrole-containing polyad for S-1 energy transfer, in which one zinc(II)-porphyrin donor is linked to two free-base corrole acceptors by a truxene linker, is reported. This polyad exhibits a rapid zinc(II)-porphyrin*free-base corrole transfer (4.83x10(10)s(-1); 298K), even faster than the tautomerization in the excited state processes taking advantage of the good electronic communication provided by the truxene bridge. Importantly, the energy transfer process shows approximately 3-fold selectivity for one corrole N-H tautomer over the other even at low temperature (77K). This selectivity is due to the difference in the J-integral being effective in both t…
Formation of meso-1,2-Bis(dimethylamino)-1,2-diphenylethane by Oxidative C-C Coupling Reaction
2005
The title compound was obtained from the reaction of N,N-dimethylbenzylamine with n-butyl lithium and sulfur in tetrahydrofuran at room temperature. Its molecular structure was investigated by means of single crystal X-ray diffraction and quantum chemical DFT methods. The formation of meso-1,2-bis(dimethylamino)-1,2-diphenylethane is likely to be due to an unusual α-deprotonation of N,N-dimethylbenzylamine, instead of the well known ortho-lithiation, with a subsequent oxidative C-C coupling of the anions. Ab initio calculations of the corresponding α- and o-deprotonated anions of N,N-dimethylbenzylamine showed the former to be more stable than the latter, due to delocalisation of the negati…
A Versatile Palladium/Triphosphane System for Direct Arylation of Heteroarenes with Chloroarenes at Low Catalyst Loading
2010
International audience; Put a ring on it: The use of an air-stable, robust palladium/tridentate phosphane catalyst in direct C[BOND]H and C[BOND]Cl activation reactions is reported (see scheme; DMAc=N,N-dimethylacetamide, TBAB=tetra-n-butylammonium bromide). Electron-rich, electron-poor, and polysubstituted furans (X=O), thiophenes (X=S), pyrroles (X=NR5), and thiazoles were arylated with chloroarenes in the presence of the catalyst.
Disciplinārsodu piemērošanas prakse ieslodzījuma vietās
2016
Piemēroto disciplinārsodu skaits ieslodzījuma vietās ir milzīgs. Lai gan katru gadu to skaits samazinās, prakse līdz šim neliecina par būtiskām pozitīvām tendencēm, pastāv samērā novecojusi disciplinārsodu piemērošanas sistēma. Maģistra darba mērķis ir noskaidrot, kāda ir piemēroto disciplinārsodu prakse ieslodzījuma vietā, izvērtēt pārkāpumu raksturu attiecībā pret piemēroto disciplinārsodu un noskaidrot vai disciplinārsodu piemērotājs ievēro vienlīdzības principu attiecībā pret pārkāpumu un disciplinārsodu, kā arī izveidot ieskatu kādai vajadzētu būt mūsdienīgais disciplinārsodu piemērošanas sistēmai. Izanalizējot Ieslodzījuma vietu pārvaldes gada publiskos pārskatus, ieslodzīto lietu mat…
Tiesneša goda un cieņas aizsardzība Latvijas Republikā
2018
Demokrātiskas tiesiskas valsts vērtību sistēmā noteikti principi ,kurus valsts pienākums ir ne tikai ieverot, bet arī nodrošināt, viennozīmīgi šiem principiem pieskaitāmi Cilvēka gods un cieņa ir viena no būtiskākajām konstitucionālajām vērtībām, kas cilvēkam piemīt neatkarīgi no personiskajām īpašībām, kuru saskaņā ar demokrātiskās tiesiskas valsts vērtību sistēmu valstij ir ne tikai jāievēro , bet arī jānodrošina. Tiesnešu goda un cieņas aizsardzības nepieciešamība noteikta ar uzlikto amata pienākumu pildīšanu. Pētnieciskā darba izpētes robežas ir tiesnešu goda un cieņas aizsardzība Latvijas Republikā ,kā demokrātiskā tiesiskā valstī. Autore izpēta tiesu varas vietu un lomu demokrātiskā v…

Alternative Systems: The Interplay between Criminal Groups’ Influence and Political Trust on Civic Honesty in the Global Context
2023
Individuals’ endorsement of standards of civic honesty is necessary for democracies to flourish. A critical driver of civic honesty is the relationship of trust between individuals and institutions. Research has yet to systematically assess the contextual factors that may moderate this relationship. In the present study, we examined the societal influence of organized criminal groups. Criminal groups operate as alternative systems of authority that erode the reliability of institutions' moral standards. We employed a new indicator that quantifies their societal influence to test the hypothesis that the association between individuals’ political trust and civic honesty would weaken in countr…
