Abstract:
Malaria poses the greatest threat of all parasites to human life. Current vaccines and efficacious drugs are available however their use is limited due to toxicity, emergence of drug resistance, and cost. The discovery of an alternative pathway of isoprenoid biosynthesis, the non-mevalonate pathway, within the malarial parasite has resulted in development of novel anti-malarial drugs. 1-Deoxy-D-xylulose-5-phosphate (DOXP) reductoisomerase, the second enzyme in this pathway, is responsible for the synthesis of 2-C-methyl-D-erythritol 4-phosphate (MEP) in an intramolecular rearrangement step fol

Abstract:
Tese de Doutoramento em Ciências Veterinárias, na especialidade de Sanidade Animal.<br>African swine fever virus (ASFV) is a nucleo-cytoplasmic large DNA virus which infects all members of the family Suidae, causing a fatal disease of domestic swine and wild boar. Since no effective vaccine or treatment is available, ASF is considered a global threat for pig husbandry. The ASFV genome encodes among others, enzymes required for virion assembly, genome transcription and replication, including a putative histone-like protein, pA104R. In bacteria, these proteins perform topological modification of

Abstract:
Nucleic acids have proven to be viable targets for small molecule drugs. While many examples of such drugs are detailed in the literature, only a select few have found practical use in a clinical setting. These currently employed nucleic acid targeting therapies suffer from either debilitating off-target side effects or succumb to a resistance mechanism of the target. The need for new small molecules that target nucleic acids is evident. However, designing a novel drug to bind to DNA or RNA requires a detailed understanding of exactly what binding environments each nucleic acid presents. In an

Abstract:
The aim of this research is to design and implement a program that will be able to manipulate multiple algebraic expressions and transform them to a 'normalised form' . The expression to be manipulated is user defined (the user will be able to input an expression or read it from a file). This expression will be read in by a scanner and checked with a parser using a set of grammar rules which are to be defined later on. The expression will be able to contain constants (both real and imaginary), identifiers (strings or individual characters) and operators which include +, -, *, /, ( ), A (power

The purpose of this thesis will be to defend R. G. Collingwood's claims about the existence, and the significance, of Absolute Presuppositions. This defense will fall into three main sections. In the first section, I will provide a detailed critical examination of the methods of metaphysical analysis prescribed by Collingwood for uncovering Absolute Presuppositions in the first place: the 'logic of question and answer'. In the second section, I will draw attention to what I take to be the main problem with the Essay on Metaphysics: the fact that this method of metaphysical analysis is never ap

Abstract:
Quantitative aspects of systems, like the maximal consumption of resources, can be modeled by weighted automata. The usual approach is to weight transitions with elements of a semiring and to define the behavior of the weighted automaton by mul- tiplying the transition weights along a run. In this thesis, we define and investigate a new class of weighted automata over unranked trees which are defined over valuation monoids. By turning to valuation monoids we use a more general cost model: the weight of a run is now determined by a global valuation function. Besides the binary cost functions im

Abstract:
Swear words are highly colloquial expressions that have the capacity to sig- nal the speaker’s affective states, i.e., to display the speaker’s feelings with respect to a certain stimulus. For this reason, swear words are often called expressives. Which linguistic mechanisms allow swear words display affective states, and, more importantly, how can such ‘affective content’ be character- ized in a theory of meaning? Even though research on expressive meaning has produced models that integrate the affective aspects of swear words in a compositional framework, there is extensive evidence t

Abstract:
Conditional gene expression and conditional mutants provide a means to modulate the expression of specific genes and to control the activity of their protein products in vivo, so as to be able to study their effects on the cell. Conditional mutants are functional under one set of conditions, termed ‘permissive’, while under other conditions that are ‘restrictive’, they become non-functional. The wild-type (Wt) is functional under both these conditions. Conditional mutants are especially useful for studying essential or lethal genes in an organism.

Abstract:
This dissertation thesis deals with the work of three contemporary Czech artists - Josef Bolf, Jakub Špaňhel and Lubomír Typlt. The reason for choosing these three was the fact that all of the artists represent the same generation which entered the art scene in the late 1990s and their canvases can be equally described as expressive, although right at first glance there are noticeable differences in the intervention of the emotional and sense elements which participated in the creation process of the work of art, but also in its content. Contemporary expressive paintings are influenced by the

Abstract:
Modifying milk fat composition to enhance its content of valuable fatty acids (FA) is required to meet the needs of a society which is becoming better informed about the relationship between diet and health. Manipulating the cow’s diet is an effective, natural way to modify the amount and composition of milk fat of cows. The two main factors that affect the cow’s diet concern management system (MS; pasture vs. confinement), and supplementation of diets with lipid supplements. Marine oils specifically are fed to enhance milk with n-3 long-chain polyunsaturated FA (n-3 LC-PUFA). The effects of s
