We present a mass transport model based on surface diffusion for metal-particle-assisted nanowire growth. The model explains the common observation that for III/V materials thinner nanowires are longer than thicker ones. We have grown GaP nanowires by metal-organic vapor phase epitaxy and compared our model calculations with the experimental nanowire lengths and radii. Moreover, we demonstrate tha
This paper proposes a new dynamic mode of generating bioanalytical arrays in microfluidic systems, based on ultrasonic trapping of microbeads using acoustic forces in standing waves. Trapping of microbead clusters in an array format within a flow-through device is demonstrated for the first time using a device with three integrated ultrasonic microtransducers. The lateral extension of each trappin
The growing field of biotechnology is in constant need of binding proteins with novel properties. Not just binding specificities and affinities but also structural stability and productivity are important characteristics for the purpose of large-scale applications. In order to find such molecules, libraries are created by diversifying naturally occurring binding proteins, which in those cases serv
Context: Estrogens regulate bone mass by binding to the estrogen receptor (ER)-alpha as well as ER-beta. The specific ER -cofactor retinoblastoma-interacting zinc finger protein (RIZ)-1 enhances ER alpha function in the presence of estrogen. Objective: The objective of the study was to determine whether a RIZ P704 insertion (+)/ deletion (-) (indel) polymorphism modulates the impact of estradiol o
We have identified a novel von Willebrand factor/fibrinogen/selectin-independent, platelet adhesion-promoting function of vascular PG-M/versicans that may be relevant in normal venous thrombosis and critical in atherosclerotic conditions. A purification scheme was devised to obtain vascular versicans, which by biochemical, immunochemical, and ultrastructural means were asserted to be 1) composed p
A methodology for the rapid and quantitative analysis of phosphorylation sites in proteins is presented. The coupling of capillary high-performance liquid chromatography (HPLC) to electrospray ionization mass spectrometry (ESI-MS) allowed one to distinguish phosphorylation sites based on retention time and mass difference from complex peptide mixtures. The methodology was first evaluated and valid
Background: We evaluated the efficacy and safety of low-dose budesonide/formoterol, 80 mug/4.5 mug, bid in a single inhaler (Symbicort Turbuhaler; AstraZeneca; Lund, Sweden) compared with an increased dose of budesonide, 200 mug bid, in adult patients with mild-to-moderate asthma not fully controlled on low doses of inhaled corticosteroid alone. Methods: All patients received budesonide, 100 jig b
As the child grows up it becomes more and more a part of the adult world of communication and understanding. Semiotic studies of the development of signs in children are remarkably few, as if the mere existence of signs were taken for granted. The studies in the child’s cognitive development conducted by Piaget and Vygotsky in the last century still have the capacity to influence theoretical claim
Popular Abstract in Swedish Svenska Pommerns historia är en del av den svenska historien. Mellan 1648 och 1815 hörde den tyska Östersjöprovinsen till det svenska väldet. Denna avhandling skildrar människorna och deras syn på Sverige under de sista hundra åren av svensk tillhörighet mellan 1720 och 1815. Hur påverkades provinsens invånare av att å ena sidan räkna sig till den tyska kulturen och å aBetween 1648 and 1815, Swedish-Pomerania, at the Baltic shore, belonged to the crown of Sweden. It was both a part of the Holy Roman Empire of German Nation and the Swedish realm. The port town of Stralsund played a key roll in the Swedish economy at the Baltic Sea, whereas the university town of Greifswald was the intellectual centre. On a cultural level, this situation opened up for a double ins

In the present thesis the development and application of a novel laser diagnostic system for high speed spectroscopic imaging of turbulent combustion phenomena is presented. The system is capable of recording sequences of up to 8 images with a separation between consecutive images as short as microseconds. The system allows a number of established laser diagnostic techniques to be used, extending
Popular AbstractLandsbygdens landskap förändras ständigt. Ekonomi, teknik och politik används ofta för att förklara det som sker, men ingen av dessa krafter verkar direkt i landskapet. I praktiken är det beslut som fattas lokalt av enskilda brukare och markägare som sätter spår. Landskapet är där sammanvävt med den sociala miljön, och markanvändningen en integrerad del av den enskildes liv. Hur seFarmers and Landscape. Owners and farmers relations to their land, and the prospects for sustainable land use. In a transition towards sustainability, rural land use is of certain interest, owing to the environmental impact of modern farming and forestry, and also to its potential role in a recycling society. The prospects for sustainable land use depend on the farmers. Their conception of sustai
