The role of lipid metabolism in the acquisition of desiccation tolerance inCraterostigma plantagineum: a comparative approach
2013
Summary Dehydration leads to different physiological and biochemical responses in plants. We analysed the lipid composition and the expression of genes involved in lipid biosynthesis in the desiccation-tolerant plant Craterostigma plantagineum. A comparative approach was carried out with Lindernia brevidens (desiccation tolerant) and two desiccation-sensitive species, Lindernia subracemosa and Arabidopsis thaliana. In C. plantagineum the total lipid content remained constant while the lipid composition underwent major changes during desiccation. The most prominent change was the removal of monogalactosyldiacylglycerol (MGDG) from the thylakoids. Analysis of molecular species composition rev…
Inferring Phytoplankton, Terrestrial Plant and Bacteria Bulk δ¹³C Values from Compound Specific Analyses of Lipids and Fatty Acids.
2015
Stable isotope mixing models in aquatic ecology require δ13C values for food web end members such as phytoplankton and bacteria, however it is rarely possible to measure these directly. Hence there is a critical need for improved methods for estimating the δ13C ratios of phytoplankton, bacteria and terrestrial detritus from within mixed seston. We determined the δ13C values of lipids, phospholipids and biomarker fatty acids and used these to calculate isotopic differences compared to the whole-cell δ13C values for eight phytoplankton classes, five bacterial taxa, and three types of terrestrial organic matter (two trees and one grass). The lipid content was higher amongst the phytoplankton (…
Regional metacommunities in two coastal systems: spatial structure and drivers of plant assemblages
2014
Aim Biogeographical patterns in metacommunities are still poorly understood, and different processes are expected to occur in different habitats. We analysed the regional plant metacommunities of coastal habitats to test whether (1) the influence of space and climate differs between two habitats differentiated along the seashore–inland gradient, and (2) regional variation in species composition of these habitats can be ascribed to different metacommunity paradigms. Location The entire coast of the Iberian Peninsula, south-western Europe. Methods We collected data on the plant species composition of coastal sites on sand dunes across 3000 km of coastline. The sites were classified into two h…
EFFETTI LOCALI E D’AREA GENERATI DALLE MISURE DI MODERAZIONE DELLA VELOCITÀ. UN BILANCIO DA CONSIDERARE IN SEDE DI PIANIFICAZIONE
2008
Le strategie finalizzate al miglioramento della sicurezza stradale si muovono, in generale, secondo due finalità distinte: - da un lato, di contenere la gravità delle conseguenze di comportamenti di guida a rischio attraverso l’installazione di dispositivi utili per limitare i danni agli occupanti del veicolo in caso di urto; - d’altro lato, di impedire (o quanto meno scoraggiare) comportamenti di guida imprudenti attraverso l’adozione di misure idonee ad allertare gli utenti e ad indurli a comportamenti non trasgressivi. Alla seconda finalità sono riconducibili i dispositivi di moderazione della velocità, i quali, agendo sui comportamenti di guida, mirano a prevenire l’insorgere di inciden…

Tulkinta empirismin tieto-opista : tietoteoreettinen analyysi David Humen, A.J. Ayerin ja Eino Kailan empiristisistä tietokäsityksistä
2011
Tämä pro gradu -tutkielma käsittelee empirismin tieto-oppia. Analysoitavina ovat tietoteoriassa vaikuttaneiden David Humen (1711–1776), A. J. Ayerin (1910–1989) sekä Eino Kailan (1890–1958) tietokäsitykset. Tulkintakulma on maltillisen valistushistoriallinen. Tutkimuksessa noudatetaan alkuperäistekstejä luettaessa suopeuden periaatetta, mutta esitetään myös kriittisiä huomioita itse oppeja kohtaan sekä pohditaan itse empiristisen tieto-opin mahdollista kehityskelpoisuutta. Tutkielma koostuu kahdesta pääluvusta. Ensimmäisessä luvussa tarkastellaan käsiteltävien filosofien metafysiikkakriittisiä ja verifikationistisia tietokäsityksiä. Niin Hume, Ayer kuin Kailakaan eivät katso metafysiikan ol…

The Broker in Pornography and Violence: Lou Reed in Lulu’s World
2020
The article analyses the literary and cultural layers of Lulu, the album published by Lou Reed in collaboration with Metallica, based on Frank Wedekind’s two modernist dramas: Earth Spirit (1895) and Pandora’s Box (1904). In Reed’s reinterpretation, the two plays become his means through which he enters the area of disturbing perversion and graphic pornography. Consequently, Reeds seems to follow Susan Sontag’s diagnosis according to which the goal of pornographic literature is to disorient and to disturb mental balance. In the case of Lulu, it demonstrates Reed’s strategies of crossing the borders between what is commonly accepted and what is rejected because of its non-normative quality. …
