Popular Abstract in Swedish Mycorrhiza är en samexistens mellan trädrötter och svampar i jorden. Svampen förser trädet med mineralnäringsämnen från jorden och i utbyte får den socker från trädet. Sockret produceras via fotosyntesen och transporteras sedan ner till rötterna där de förs vidare till svamphyferna. Det har visats att mycorrhizasvampar kan ta upp näringsämnen direkt från mineraler i jEctomycorrhiza are a symbiosis between trees and soil inhabiting fungi. The fungal hyphae ensheath the fine roots creating a mantle and grow in between root cells to create the Hartig net, where the exchange of carbon and mineral nutrients occurs. The ectomycorrhizal fungus is dependent on the host tree to receive the carbon it needs to grow. Trees with different nutrient deficiencies differ in t

Popular Abstract in Swedish Hos djur är det vanligt att hannarna slåss om att få para sig med honorna, medan honorna är mer kräsna i sitt val av partner. Är det möjligt att växter gör på samma sätt? I min avhandling har jag visat hur pollen tävlar om att få befrukta de honliga fröämnena i pistillen hos styvmorsvioler (Viola tricolor). Det ligger även i honans intresse att välja en partner som prodAccording to the theory of sexual selection, traits can evolve because they confer a mating advantage in competition with members from the same sex. In animals, sexual selection is considered as an important evolutionary force. In this thesis I have investigated the potential for sexual selection in plants. I have concentrated on the phase of reproduction that occurs after pollinators have deposit

The book gathers a number of articles devoted to new approaches towards research into freemasonry as a socio-cultural phenomenon in British society.

Background: The Clubfoot Assessment Protocol (CAP)is a multi dimensional instrument designed for longitudinal follow up of the clubfoot deformity during growth. Item reliability has shown to be sufficient. In this article the CAP's validity and responsiveness is studied using the Dimeglio classification scoring as a gold standard. Methods: Thirty-two children with 45 congenital clu

This paper explores the idea that abstract Agree is a precondition on Merge and an integrated part of it. That is, an element F merges with the structure X only if the relation of Agree holds between the two (the Agree Condition on Merge). The relation of Agree holds between F and X iff X contains an active feature fx that matches F. Move is forced by an inactive intervener ?x between F and fx, wh

Present power system will face great challenges in several areas depending on the market economy, extensive global integration and constant need for more electric power, which will force the system to operate much closer to its stability limits. Meeting these challenges may involve improving and complementing or even total restructuring of the power systems.New technologies are emerging such as re

It has been proposed that the EU Ecodesign Directive can promote resource efficiency through relevant ecodesign requirements. This paper examines the potential for rare earth element (REE) resource efficiency improvements in the event the current regulation for electric motors under the Ecodesign Directive is to be extended to comprise REE-based permanent magnet motors. The research is based on li

Det grundläggande problem som denna bok behandlar är en till synes växande klyfta mellan världsvida relationer och människors behov av geografisk närhet och ögonkontakt. Författaren behandlar frågor som rör tekniken och den sociala kommunikationens villkor, eller uttryckt på annat sätt, människans förmåga och möjligheter att bemästra det geografiska rummet. Europas geopolitiska karta känneteckna

This thesis addresses; (1) the microdialysis experiment, application and methodology to maximise its performance when sampling from enzymatic bioprocesses, (2) electrochemical detection and electrochemical oxidation of carbohydrates on Au as well as Cu electrodes in alkaline solutions, and (3) coupling and maximising the performance of a microdialysis sampling based high performance anion exchange

Popular Abstract in Swedish I flera tusentals år har människan använt sig av naturen till hjälp för att bota åkommor och krämpor. Det som hon har dragit nytta av då är att alla växter och plantor producerar flertalet små föreningar till skydd eller nytta för plantan. Dessa som föreningar kan då interagera med andra växter och organismer till exempel som ett skydd mot att bli uppäten, som en lockelNatural products have until recently provided the only remedy for treatment of diseases. The development of modern chemistry in the last centuries has opened the door for tapping into the chemical diversity found in nature. Synthetic natural products, together with analogues, are an important piece in the puzzle towards curing many ailments. In this thesis, synthetic endeavors towards different bi
