Transmission Electron Microscopy of Nanowires: Influence of Doping and Etching on Polytypism in InP

Semiconductor nanowires have many properties which makes them interesting for future electronic devices. The fact that they have very small diameters allow them to combine different III-V materials into heterostructures, and makes it possible to grow them on Si substrates which are the basis of nearly all current semiconductor technology. It also allows them to adopt the wurtzite crystal structure

Characterization of Chlamydia trachomatis omp1 genotypes among sexually transmitted disease patients in Sweden.

A method for detection and genotyping of genital Chlamydia trachomatis infections based on omp1 gene amplification and sequencing was developed. DNA was extracted from urogenital or urine samples using a Chelex-based method, and an approximately 1,100-bp-long fragment from the omp1 gene was directly amplified and sequenced. Genotyping was performed by BLAST similarity search, and phylogenetic tree

Species interactions govern evolutionary and ecological effects of population harvesting

Popular Abstract in Swedish FISKETS EFFEKTER BEROR PÅ SAMSPELET MELLAN ARTER Fiske och jakt, så kallad populationsbeskattning, påverkar den fiskade eller jagade populationen på en rad olika sätt. Den direkta effekten är uppenbar: dödligheten ökar, och antalet individer i populationen minskar. I förlängningen påverkar denna minskning också andra arter, som t ex äter eller äts av individerna i den bHarvesting changes population abundance and can affect adaptation of several life-history traits. Harvesting can also have indirect effects ? effects on non-target species and secondary effects on target species ? because interactions between species in a community determine the relevant ecological and evolutionary feedback environment. Species interactions therefore influence the effect of harves

Problem Gaming in an everyday perspective (Research Panel)

In this panel we take a critical look at problem gaming. We question existing approaches that tend to draw on concepts from clinical psychology and we introduce everyday life and the general wellbeing of youth as an alternative perspective.

Reading achievement : Its relation to home literacy, self-regulation, academic self-concept, and goal orientation in children and adolescents

Popular Abstract in Swedish Doktorsavhandling undersöker hur förutsättningar i hemmet, självreglering, akademisk självbild och målorientering påverkar läsförmåga. Att kunna läsa bra är grundläggande för att kunna fungera väl i det moderna samhället där man måste kunna läsa komplicerade texter. Då larmrapporter, kring hur många ungdomar som slutar skolan utan att kunna läsa och skriva, regelbundet The studies in this doctoral thesis investigated how home literacy, self regulation, academic self-concept, and goal orientation influence reading ability. Study 1 investigated the effect of family-based prerequisites, reading attitude, and self-regulated learning on reading ability. Students (n= 4,018) in the eighth grade answered the IEA reading literacy test and the SRLQ. Structural Equation Mo

Structure and Interactions of the Extracellular Matrix Protein PRELP

Popular Abstract in Swedish Bindväv är ett samlingsnamn för vävnader som ger form och struktur i olika organ i kroppen. I brosk och ben utgör bindväven hela eller stora delar av organet, medan i andra organ, t.ex. muskel, är bindväven endast en liten del. Bindväv karaktäriseras av ett nätverk av proteiner och polysackarider (extracellulär matrix), som omger och produceras av en relativt liten andeThis thesis describes the structure and interactions of a novel extracellular matrix protein - PRELP (proline arginine-rich end leucine-rich repeat protein). The amino acid sequence of PRELP showed that it belonged to the leucine-rich repeat (LRR) protein family in connective tissues. The main part of PRELP is composed of 10 LRRs flanked by disulfide bridges at the amino- and carboxy-terminal end

Environmentally Responsive Surface Coatings of Polyion-Surfactant Ion Complex Salts

Popular Abstract in Swedish Polymerer och tensider är molekyler vi stöter på i vårt vardagliga liv, när vi bär hem våra matvaror i plastkassar, tvättar håret, målar huset eller tar en värktablett. Klassificeringen polymer är väldigt bred och innefattar allt från naturliga polymerer som cellulosa, till syntetiska polymerer som polystyren. Polymerer består av små, repeterande enheter, kallade monomeComplexes formed between oppositely charged polyions and surfactant ions are known to have very rich phase behaviour in bulk solution. The work in this thesis investigates the possibilites of using such complexes as surface coatings. Stoichiometric polyion-surfactant ion complexes “complex salts” (CS) consisting of alkyltrimethylammonium surfactant ions and polyacrylates are typically insoluble i

On entropies of occupancy distributions

Occupancy models for equal or unequal objects distributed into equal or unequal cells can be represented by random partitions of integers or sets and also by randomly colored and labeled graphs. Applications of occupancy models to statistical disclosure control and to cluster inference in random graphs motivate an interest in entropies of occupancy distributions. We determine and compare entropies
