Bībeles intertekstualitāte Migela de Unamuno romānā “Svētais Manuēls Labais Moceklis”

2018

Šis darbs ir veltīts Migeļa de Unamuno (Miguel de Unamuno) Bībeles intertekstuālu atsauču (tiešu, netiešu) izpētei Migeļa de Unamuno (Miguel de Unamuno) romānā: “Svētais Manuēls Labais moceklis” Pētījumā ir četras nodaļas, kas veido divas daļas: pirmā teorētiskā, kas sastāv no trijām pirmajām nodaļām un definē intertekstualitātes konceptu, parāda Unamuno dzīvi un darbu, īpaši romānu "Svētais Manuēls Labais moceklis". Otrā ir praktiskā daļa, kas sastāv no ceturtās nodaļas, tās mērķis ir atklāt un klasificēt bībliskās intertekstualitātes romānā. Galvenā uzmanība teorētiskajā daļā tiks pievērsta Džulijas Kristeva (Julia Kristeva) un Žerarda Ženeta (Gerard Genette) pētījumiem par to, kā viņi in…

Surface hydrographic changes at the western flank of the sicily channel associated with the last sapropel

2021

Abstract In the eastern Mediterranean Sea, the early Holocene was characterized by major climatic and oceanographic changes that led to the formation of the last sapropel (S1) between 10.8 and 6.1 kyr cal. BP. These hydrographic changes might have altered the water exchange between the eastern and western Mediterranean sub-basins through the Strait of Sicily, but the existing evidences are inconclusive. In the present study we show new evidence from sediment core NDT-6-2016 located at the western flank of the Sicily channel, a key location to monitor the surface/intermediate water exchange between the two Mediterranean sub-basins. We perform paleo-hydrographic reconstructions based on plank…

Macrofungi in Mediterranean maquis along seashore and altitudinal transects

2014

In semi-arid Mediterranean environments, fungal activity is fundamental for buffering biotic and abiotic stress to the plant and for sustaining a vegetation cover. Despite the important role that fungi play in habitats stability, mycological data from Mediterranean ecosystems are scarce and fragmentary. We investigated fungal diversity in several areas characterized by Mediterranean maquis, from continental Italy, Sicily, and Greece in order to contribute to the analysis of distribution, ecology, and diversity of macrofungi in evergreen sclerophyllous shrublands at different elevation and distance from the seashore across the Mediterranean Basin. Several fungal taxa that are remarkable due …

The hemagglutinin of Staphylococcus saprophyticus binds to a protein receptor on sheep erythrocytes.

1997

Staphylococcus saprophyticus, an important cause of urinary tract infections, produces two major surface proteins, the S. saprophyticus surface-associated protein (Ssp) and the hemagglutinin, which mediates fibronectin binding and also functions as the major adhesion of the organism. The hemagglutinating and fibronectin binding functions probably reside on different parts of the molecule. To identify a receptor on eukaryotic cells, binding and inhibition studies with acidic and neutral glycosphingolipids, carbohydrates, and proteins of sheep erythrocyte membranes were conducted. S. saprophyticus did not bind to any glycosphingolipid and no inhibition was observed when hemagglutination assay…

Expression of Staphylococcus saprophyticus surface properties is modulated by composition of the atmosphere.

1995

Expression of two major surface proteins of Staphylococcus saprophyticus, the haemagglutinin and the Staphylococcus saprophyticus surface-associated protein (Ssp), requires carefully defined culture conditions. The Ssp is produced when bacteria are grown on agar, whereas expression of the haemagglutinin requires growth in broth. We sought to identify the environmental signals that are responsible for this modulation. Varying the pH, the osmolarity of the growth medium or the temperature did not influence expression of the proteins. In contrast, growth in an anaerobic atmosphere increased haemagglutination titres and fibronectin binding (both mediated by the haemagglutinin) but suppressed pr…

Conflicting coccolithophore and geochemical evidence for productivity levels in the Eastern Mediterranean sapropel S1

2011

Abstract The cyclic development of anoxic conditions in the eastern Mediterranean deep sea waters is one of the most fascinating research topics in paleoceanographic studies. In combination with bottom water stagnation, enhanced primary production is a common explanation for the deposition of organic-rich layers (sapropels). This is supported by extensive evidence from both geochemical and micropaleontological studies. The correspondence of recent sapropel layers with peaks of the lower photic zone coccolithophore species Florisphaera profunda has been interpreted as a proxy for the development of a deep chlorophyll maximum (DCM), due to the pycnocline/nutricline shallowing into the lower p…
