Characterisation of humic acids in fen peat
2020
Fens store significant amounts of organic matter and thus are of high importance from the perspective of the organic carbon biogeochemical cycle. Fen peat comprises moderately to highly decomposed higher plant remains with relatively high mineral matter content. Humic acids form the major part of fen peat organic matter; they are also the most refractory and recalcitrant natural substances to degradation, and thus they contain essential information regarding mire and peat development over large periods of time as well as the organic carbon biogeochemical cycle. Moreover, humic substances in fen peat are a prospective resource for applications in agriculture and other sectors. The aim of thi…
Mimonoside D: a new triterpenoid saponin from Mimosa diplotricha Sauvalle (Fabaceae)
2021
A new triterpenoid saponin (Mimonoside D: 3-O-��-L-arabinopyranosyl-3��-hydroxyolean-12-en-28-oic acid 28-O-��-D-xylopyranosyl-(1���2)-��-D- glucopyranoside ester (1)) was isolated from the aerial parts of Mimosa diplotricha Sauvalle together with nine known compounds: 7,4���-dihydroxyflavone (2), kaempferol (3), lupeol (4), betulinic acid (5), ��-sitosterol (6), ��-sitosterol-3-O-��-D-glucopyranoside (7), lutein (8), 5,2���-dihydroxy-7,4���,5���-trimethoxyflavone (9) and vitexin (10). Their structures were elucidated on the basis of spectroscopic (1 D and 2 D nuclear magnetic resonance) and high-resolution mass spectrometric data as well as by comparison of their spectral data with those o…
Orientation-Dependent Handedness of Chiral Plasmons on Nanosphere Dimers: How to Turn a Right Hand into a Left Hand
2016
Optical activity, which is used as a discriminator of chiral enantiomers, is demonstrated to be orientation dependent on individual, and nominally achiral, plasmonic nanosphere dimers. Through measurements of their giant Raman optical activity, we demonstrate that L/R-handed enantiomers can be continuously turned into their R/L-handed mirror images without passing through an achiral state. The primitive uniaxial multipolar response, with demonstrable broken parity and time reversal symmetry, reproduces the observations as resonant Raman scattering on plasmons that carry angular momentum. The analysis underscores that chirality does not have a quantitative continuous measure and recognizes t…
Orgānu un audu izņemšana no cilvēka - cilvēktiesību pārkāpums?
2017
Darbā “Orgānu un audu izņemšana no cilvēka – cilvēktiesību pārkāpums?” tiek izpētīta likumīga cilvēka orgānu un audu transplantācija, kā arī nelikumīga orgānu un audu izņemšana, kas ir neatļauta un noziedzīga darbība. Orgānu un audu izņemšanas cilvēktiesību jautājums saasinājās pēdējo 40 gadu laikā, sakarā ar zinātnes attīstību transplantācijas jomā un cilvēktiesību lomas pieaugumu medicīnas un pacientu tiesībās. Tāpēc bakalaura darbā autore apskata orgānu un audu izņemšanas juridiskās īpatnības un tas rezultātā radītos cilvēktiesību aizskārumus. Orgānu un audu izņemšanas problēma mūsdienās ir ļoti svarīga un izplatīta, jo orgānu un audu pieprasījums ir lielāks nekā orgānu piedāvājums, tāpē…
L’educazione familiare e il consumo del cinema negli anni Cinquanta tra Nord e Sud d’Italia
2017
In questo articolo, il cinema degli anni Cinquanta viene indagato come mezzo di consumo e come strumento di socializzazione delle masse italiane, in un confronto tra il Nord industrializzato e il Sud ancora prevalentemente agricolo, ma anche tra le zone urbane e quelle rurali, tra classi e tra generi differenti. Seguendo la storia del cinema italiano nel «decennio più lungo del secolo breve», dal neorealismo al melò alla commedia, emerge che il cinema entrava nella vita delle famiglie italiane plasmandole, ridisegnando identità e costruendo nuovi immaginari. Nonostante il diverso approccio con cui le famiglie italiane andavano al cinema, questo fu vissuto come una fonte di istruzione che co…
The good, the bad and the ugly: images of the foreigner in contemporary criminal law
2018
Since the end of the Second World War, the criminal law of Western states has tried to legitimate itself, in basically democratic-republican terms, as primarily addressed towards citizens. During approximately the last 20 years, however, new dimensions of criminal law have emerged, which refer paradigmatically (not to the citizen, but) to the foreigner and subject him/her to worse legal treatment than that which is considered legitimate when either citizens or ‘good’ foreigners are concerned. Next to the ideal-type of the citizen criminal law (also applicable, by assimilation, to the ‘good’ foreigner) a criminal law for ‘ugly’ mass-foreigners (crimmigration) and one for ‘bad’ foreigners (en…
Análisis de la expresión de miRNA circulantes en pacientes con infarto agudo de miocardio y su relación con citoquinas. Repercusión funcional en cult…
2019
Las enfermedades cardiovasculares, en concreto el síndrome coronario agudo (SCA), son la principal causa de muerte en hombres y mujeres en todo el mundo. El SCA es la manifestación clínica de la isquemia miocárdica, producida por la reducción del aporte sanguíneo al miocardio como consecuencia de una disminución del calibre de las arterias coronarias. La enfermedad subyacente al SCA más frecuente es la aterosclerosis, un proceso inflamatorio iniciado por la acumulación de lipoproteínas de baja densidad (LDL) en el espacio subendotelial en arterias de mediano y gran calibre a lo largo del sistema cardiovascular. El primer cambio funcional detectable en la lesión aterosclerótica es la disfunc…

AMBIENTE COSTRUITO E SOSTENIBILITÀ – Materiali riciclati e Design for Disassembly tra ricerca e buone pratiche
2020
In the context of environmental emergency of which the construction sector is one of the main causes – since it consumes 40% of the (embodied and operational) energy and produces about a third of the total waste – and due to the ambitious objectives set by the international community and by many countries to reduce the environmental impact of buildings during their whole life cycle, this paper wants to make a contribution to the understanding of the state of the art on cycle-based research activities, sustainable experiments and good practices that the building industry and the academy have implemented in recent years. In particular, it refers to cycle-based theoretical and experimental act…
