Abstract of chapter 1 For n >= 2 the number of mixing n-step subshifts of finite type (sft) over the alphabet {0, 1} is proven to be at least 15/16 times the number of transitive n-step sfts. A conjecture assumes the latter to be at least 2^(3*2^(n-1)-n). Abstract of chapter 2 The alternating colouring function is defined. Strings over the alphabet {0, 1} are divided in colourable and non-colouraImagine an of characters A and B. Such can be thought of as a paper strip with As and Bs written on it, one end of which one holds in the hand while the other stretches over the horizon without ever ending. Or as a calculator that displays a new character each second. Or as a printer with an infinite amount of paper and ink that unfortunately only prints As and Bs. In contrast to infinite strings

Purpose The purpose of this study is to better understand online anonymity in the global file-sharing community in the context of social norms and copyright law. The study describes the respondents in terms of use of Virtual Private Networks (VPNs) or similar services with respect to age, gender, geographical location, as well as analysing the correlation with file-sharing frequencies.

With a worldwide increase in climate-related disasters and the global temperature on the rise, the effects of climate change are already being felt. Among those most at risk are the poor in developing countries, often living in informal settlements or „slums‟. In order to reduce associated risks and strengthen people‟s own coping capacities, there is an urgent need for knowledge about the factors

The halotolerant bacterial strain BU-4, isolated from a hypersaline environment, was identified as an exopolysaccharide (EPS) producer. Pretreatment liquids of steam-exploded quinoa stalks and enzymatic hydrolysates of Curupaú sawdust were evaluated as carbon sources for EPS production with the BU-4 strain, and the produced EPS was characterized using FTIR, TGA, and SEM. Cultivation was performed

Matrester i Chiles huvudstad kan driva bussar och ge landet skjuts i klimatfrågan. Två tredjedelar av stadsbussarna i Santiago de Chile skulle kunna drivas av biogas, om det organiska avfallet i landets kärnregion tas tillvara på. Förändringen hade dessutom minskat Chiles totala klimatpåverkan med 2%. I Sverige är vi vana vid att åka stadsbuss där det glatt annonseras att den drivs av matavfalle

In order to reduce the net climate impact of concrete production, it is necessary for the industry to undertake several actions. Among these is to include fly ash and slag as supplementary cementitious materials. Accordingly, this project has studied concrete containing low-calcium fly ash or ground-granulated blast-furnace slag. In incorporating fly ash or slag as supplementary material, the ceme

The Krüppel-associated box (KRAB) domain is a transcriptional repression module responsible for the DNA binding-dependent gene silencing activity of hundreds of vertebrate zinc finger proteins. We previously exploited KRAB-mediated repression within the context of a tet repressor-KRAB fusion protein and of lentiviral vectors to create a method of external gene control. We demonstrated that with th
