Sesquiterpene lactones and lignans from Artemisia arborescens
1997
The aerial parts of Artemisia arborescens yielded, in addition to several known compounds, a new guaianolide, a new homoditerpene endoperoxide, a new lignan of the sesamin type and a new azulene derivative.
Influence of Bacteria <i>Pseudomonas fluorescens</i> on the Properties of Latvian Clay
2014
Wide varieties of bacteria are able to produce extracellular polymeric substances (EPS) which are mostly composed of polysaccharides. It is suggested that EPS substances can alter certain clay soil properties due to their ability to adhere to the surface of mineral particles. Most common used microorganisms by the researchers for this purpose are of either genus Bacillus or genus Pseudomonas. In this study growth of bacteria P. fluorescens AM PS11 culture in locally obtained clay is studied for the purpose of establishing their influence on rheological properties of clay. An attempt to evaluate it has been made using FT-IR and XRD. Change in plasticity of clay using Atterberg limits method …
Dracoside, a New Steroidal Saponin fromHelleborus purpurascens
1994
Abstract A new steroidal saponin, 1-O-[6-O-acetyl-β-D-galactopyranosyl]-24-O-[β-D-apiofuranosyl-(1→3)-4-O-acetyl-α-L-rhamnopyranosyl-(1→4)-β-D-xylopyranosyl-(1→3)-α-L-arabinopyranosyl]-dracogenin, was isolated from the roots of Helleborus purpurascens and named dracoside. Structure elucidation was performed by chemical transformations and various spectroscopic methods, mainly 2D NMR techniques (COSY, HMQC, HMBC).
Succinate dehydrogenase functioning by a reverse redox loop mechanism and fumarate reductase in sulphate-reducing bacteria.
2006
Sulphate- or sulphur-reducing bacteria with known or draft genome sequences (Desulfovibrio vulgaris, Desulfovibrio desulfuricans G20, Desulfobacterium autotrophicum [draft], Desulfotalea psychrophila and Geobacter sulfurreducens) all contain sdhCAB or frdCAB gene clusters encoding succinate : quinone oxidoreductases. frdD or sdhD genes are missing. The presence and function of succinate dehydrogenase versus fumarate reductase was studied. Desulfovibrio desulfuricans (strain Essex 6) grew by fumarate respiration or by fumarate disproportionation, and contained fumarate reductase activity. Desulfovibrio vulgaris lacked fumarate respiration and contained succinate dehydrogenase activity. Succi…
Conrad Under Polish Eyes - or: is Conrad still "one of us"?
2015
This article discusses the attitude of Polish Conrad scholars towards Conrad and his works from the very beginning of his literary career to the present day, discussing the way they have perceived Conrad’s national identity and his cultural belonging. Although I aim to present a review of Polish criticism over the years, I pay particular attention to modern criticism, i.e. that of the period since the end of the Second World War, which includes the years of de facto communist rule (1945-1989). I try to determine whether Conrad is still “one of us”, whether he can be perceived as a moralist in the twenty-fi rst century and whether there is a need for such a moralist in present-day Poland.
The long duration of the census reservativus. Credit forms and agrarian contracts between the middle ages and the modern era
2008
The census reservativus is a form of rent or annuity often misunderstood in historiographical researches; the difficult of the argument consist, generally, in the questions studied by the linguistic turn and in the plasticity of a institution swinging between the agrarian contracts and the supply of money. This form of rent has been associated for a long time with another contract, known as census consignativus, that recently has been traduced with the ambiguous term consignative emphyteusis; the evolution of the census reservativus belong to a history of longue durée and has been particularly distinguished by the fusion of locals customs with the revival of the principles of roman right in…
Deute públic i renda censalista al País Valencià en el segle XV. Una proposta d’interpretació
2018
L’emergència de la nova fiscalitat –de la Corona, de les ciutats i del regne– va ser, sens dubte, una de les grans transformacions polítiques i econòmiques del final de l’edat mitjana. Amb l’impost va aparèixer un deute públic consolidat que, en la Corona d’Aragó, es va desenvolupar mitjançant el censal, un instrument financer semblant a les rentes constituées franceses o les perpetual annuities angleses. A partir del cas del País Valencià, pot assajar-se una estimació del volum de rendes generat pel deute públic i de com es distribuïen des del punt de vista geogràfic i social. Així doncs, en aquest article s’estudia en quins nivells de la xarxa urbana es concentraven aquests recursos i qui…
La Pequeña Edad de Hielo en el Golfo de València. Procesos en deltas y sistemas de restinga-albufera. La desestabilización reciente
2023
En este proyecto de Tesis, se ha pretendido caracterizar formas, procesos y dinámica de sistemas de delta-laguna-barrera a escala de tiempo histórica relacionados con el episodio climático histórico de la Pequeña Edad de Hielo (PEH, siglos XIV-XIX) en el Golfo de València. Finalmente, también se aborda el análisis de la desestabilización de estos sistemas ante la acción antrópica y el Calentamiento Global. Los deltas, las barreras (o restingas) y los humedales (o albuferas) mediterráneos constituyen ambientes altamente sensibles a los cambios tanto de origen natural como antrópico. La franja costera del Golfo de València, formada por un conjunto prácticamente ininterrumpido de sistemas de d…
Els censos
2021
El document forma part dels materials docents programats mitjançant l'ajut del Servei de Política Lingüística de la Universitat de València. Power-point on s'expliquen els trets fonamentals dels censos, en la seua regulació al Codi civil espanyol, amb algunes referències a diversa normativa autonòmica.
«SENS E RAZOS D’UNA ESCRIPTURA». IL VANGELO OCCITANO DI NICODEMO
2018
Il poema Sens e razos d’una escriptura, noto anche come Vangelo occitano di Nicodemo, è uno dei più interessanti della letteratura religiosa in lingua d’oc, eppure è stato fino a oggi sorprendentemente trascurato. Attingendo a diverse fonti, anche di natura apocrifa, il testo prende avvio dalla passione di Gesù e dai fatti che la seguirono – tra cui lo spettacolare spaccato della Discesa agli inferi del Signore – e prosegue tracciando una storia completa della salvezza, fino al Giudizio Finale. Malgrado la pluralità di materiali eterogenei usati dall’autore, il poema presenta una chiara unità stilistica. Ma si possono soprattutto riconoscervi precise finalità politico-religiose, che ci ripo…
