  1. 21. Biological diversity values in semi-natural grasslands : indicators, landscape context and restoration

    Författare :Mathias Öster; Ove Eriksson; Martin Zobel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; connectivity; Hygrocybe; indicators; landscape history; plants; pollen limitation; species-area effects; surrogate species; Biology; Biologi;

    Sammanfattning : Semi-natural grasslands, which are a declining and fragmented habitat in Europe, contain a high biodiversity, and are therefore of interest to conservation. This thesis examines how plant diversity is influenced by the landscape context, and how plant and fungal diversity can be targeted by practical conservation using indicator species and congruence between species groups.

  3. 22. Applications of ocean transport modelling

    Författare :Hanna Corell; Kristofer Döös; Björn Kjerfve; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ocean transport modelling; connectivity; particle-tracking; sediment transport; Forsmark; marine protected areas; MPA; stream functions; heat flux; wind forcing; Carcinus maenas; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The advective motion of seawater governs the transport of almost everything, animate or inanimate, present in the ocean and those lacking the ability to outswim the currents have to follow the flow. This makes modelling of advective ocean transports a powerful tool in various fields of science where a displacement of something over time is studied. LÄS MER

  4. 23. Es-Clefts und det-Clefts : Zur Syntax, Semantik und Informationsstruktur von Spaltsätzen im Deutschen und Schwedischen

    Författare :Stefan Huber; Tyska; []
    Nyckelord :HUMANIORA; HUMANITIES; generative grammar; German sentence structure; Swedish sentence structure; split CP; relative clauses; expletives; extraposition; connectivity; predication; specification; identification.; topic-comment; projection of focus; background-focus; It-cleft constructions; copular constructions; pseudo-cleft constructions; German language and literatur; Tyska språk och litteratur ;

    Sammanfattning : This study investigates the syntax, semantics and information structure of it-cleft constructions in German and Swedish. The syntactic analysis is presented within a standard framework of generative theory. In defining genuine cleft constructions, both the syntactic and the semantic structures of clefts are taken into consideration. LÄS MER

  5. 24. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition

    Författare :Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; brain plasticity; structural plasticity; magnetic resonance imaging; voxel-based morphometry; tractography; connectivity; motor cortex; posterior parietal cortex; cerebellum; vesicular glutamate transporter;

    Sammanfattning : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. LÄS MER

  7. 25. Quantitative 3D reconstruction of porous polymers using FIB-SEM tomography -correlating materials structures to properties of coatings for controlled drug release

    Författare :Cecilia Fager; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tomography; controlled drug release; 3D; connectivity; insulating material; polymer film; soft material; focused ion beam; scanning electron microscopy;

    Sammanfattning : Porous networks are found in a wide range of different advanced and technologically important materials and influence the materials properties. The networks are active components in for example batteries, food and pharmaceuticals. The interconnectivity of a network strongly influences the transport properties. LÄS MER
