Surfactant Responsive Cross-Linked Polymer Hydrogels

The focus of the thesis is on chemically cross-linked hydrogels which drastically change their volume when immersed in solutions of different ionic surfactants (with or without added salt). The two main questions addressed are: (1) How useful are simple gel swelling experiments to the study of polymer-surfactant interactions?, and (2) How does the volume of a cross-linked polymer gel change when i

A Digital Baseband for Low Power FSK Based Receiver in 65 nm CMOS

The design of a digital baseband for a low power wireless receiver in 65 nm CMOS is presented. It consists of decimation filtering, matched filters for data detection, and preamble based synchronization. The circuit was designed using low threshold devices in both low power (LP-LVT) and general-purpose (GP-LVT) domains. The fabricated circuits were functionally verified, and silicon measurements s

Handel och mission hos kanadensiska mi’kmaqindianer under 1600-talet

Exempel från 1600-talet på förändringar av mi'kmaqs traditioner visar att mötet med den europeiska kulturen inte var konfliktfritt och mötte motstånd från mi'kmaq. Beskrivningarna om missionens snabba framgång ger inte en helt rättvisande bild. Det var missionärerna som skrev historien och de ville också framstå i en fördelaktig dager inför sina överordnade. För de mi'kmaq som samlades kring missi

On the development of interpolation - instead of a history three letters

This compilation should be viewed as a kind of prolegomena to a history of interpolation. Three letters from Mischa Cotlar, Antoni Zygmund and Olof Thorin from c. 1980 are reproduced. Thorin's letter is given in translation. These letters were written as a reply to an inquiry by the editor/translator. It is remarkable that while Thorin spent his whole professional life as an actuary, neither of hi

Experimental Studies of the Interaction of Atmospheric Aerosol Particles with Clouds and Fogs

Popular Abstract in Swedish I atmosfären finns förutom olika gaser, såsom kväve, syre, vattenånga och en mängd gaser i låga koncentrationer, även partiklar. Dessa partiklar kallas aerosolpartiklar och de kan hålla sig svävande upp till flera veckor innan de deponeras till marken igen. Moln- och dimmdroppar bildas i atmosfären genom att vattenånga kondenserar på aerosolpartiklar. Detta kan ske då lIn this work, cloud and fog droplet formation was studied in three joint field experiments. The instrument, the droplet aerosol analyser (DAA), has also been further developed and verified as part of this work. The DAA is an instrument especially developed for studies of cloud and fog droplet formation and growth. It measures the ambient size of individual droplets and interstitial particles in a

Maximal capacity partial response signaling

In this paper we investigate partial response signaling (PRS) systems that are intended to operate close to capacity. We show that finding PRS systems with maximal capacity is a rather easy optimization task. We give an alternate way of defining bandwidth for PRS systems based on capacity considerations; this differs considerably from the traditional method based on transmission power. Practical P

After Capitalism: Cyborgism

This second digital edition includes my research from 2013 until November 2015. There are many important changes from de first version. This version introduces the Technocratic Mode of Production based on the exploitation of the consumers. It includes a complete description of the cyborg society as it is today, the new castes that constitute it and the economic acts that regulate the new Mode of P

Tourists and Global Environmental Change: A Possible Scenario in Relation to Nature and Authenticity

The aim of this chapter is to discuss global environmental change (GEC) through the social construction of nature and notions of authenticity. We will discuss the social construction of nature in a specific context, namely that of different kinds of nature-based tourism. The argument will revolve around what we perceive as a shift in focus from the image of nature as thing to nature as experience,

Human Glandular Kallikrein 2

Human glandular kallikrein 2 (hK2) is a serine protease, which is predominantly expressed by the prostate gland and found in seminal plasma at mean levels of 6 mg/ml. It has 79% amino acid sequence identity with prostate-specific antigen (PSA or hK3). The aim of this work was to produce hK2 by recombinant expression technologies in order to study its biochemical and biological properties and its

Bioenergy in Ukraine: Sustainable pathways for bioenergy development

Ukraine has significant potential for bioenergy. Biomass can supply 1 EJ/year or 18% in the country’s energy balance. The major part of this is formed by agricultural residues and energy crops. Annually nearly 175 PJ can be derived from straw, which is currently not used elsewhere. At present the biofuels sector in Ukraine is not established although a number of initiatives have emerged. Biomass s

Cost-Effectiveness and Heterogeneity: Using Finite Mixtures of Disease Activity Models to Identify and Analyze Phenotypes

Heterogeneity in patient populations is an important issue in health economic evaluations, as the cost-effectiveness of an intervention can vary between patient subgroups, and an intervention which is not cost-effective in the overall population may be cost-effective in particular subgroups. Identifying such subgroups is of interest in the allocation of healthcare resources. Our aim was to develop

Plant community assembly during succession from arable fields to semi-natural grassland

Popular Abstract in Swedish Vi vill bevara naturbetesmarker och deras skönhet, vilken bland annat utgörs av de olika växtarter som förekommer där. Men idag finns det tyvärr inte många betesmarker kvar. Naturbetesmarkerna har under de senaste två sekelerna försvunnit på grund av ökad eller minskad markanvändning, där betesmarker blivit omvandlade till antingen åkermark eller skog. Bristen på betesmLarge areas of grazed, species rich semi-natural grassland were lost in Europe during the last two centuries and as a consequence led to decreases in grassland specialist species. Therefore, today the “restoration” of grassland on previously arable fields is recommended for the protection of grassland specialists. Even “substitute habitats” for lost grasslands are discussed as temporary alternativ
