Popular Abstract in Swedish Polyaminer finns i alla levande celler, såväl i bakterier som i växter, djur och människor, och utgör en mycket viktig beståndsdel i dessa. Utan dessa polyaminer kan inte cellerna växa och dela sig. Polyaminerna putrescin, spermidin och spermin bildas i cellen från aminosyran ornitin. Till sin hjälp för denna bildning har cellerna ett enzym vid namn ornitindekarboxylas The polyamines putrescine, spermidine and spermine have been shown to be involved in cell growth and differentiation, and are considered to be crucial components of the living cell. The synthesis of polyamines in the cell is strictly regulated. The first and rate-limiting step in the biosynthesis of polyamines is catalysed by the enzyme ornithine decarboxylase (ODC). Mammalian ODC has a very fast

An experiment was conducted to concentrate on the rainfall interception process of individual trees for four common species in Beijing, China, which included needle species (Platycladus orientalis and Pinus tabulaeformis) and broadleaf species (Quercus variabilis and Acer truncatum). Two types of interception storages, the maximum (Cmax) and the minimum interception storage (Cmin), were examined a

Nanowires are important candidates for use in future electronics, photonics and thermoelectrics applications. We focus here in particular on nanowires for use in thermoelectric power generation and present a method of fabricating dense uniform InAs nanowire arrays amenable to future incorporation of advanced heterostructures that could further increase the thermoelectric performance of these nanow

Denna uppsats syftar till att utreda vilken betydelse erkännandet har i brottmålsprocessen i Sverige. Uppsatsens fyra frågeställningar utgör ramen, och innefattar såväl en allmän del om bevisprövning som en djupdykning i erkännandets prövning och styrka som bevis. I uppsatsen används huvudsakligen rättsdogmatisk metod. Dock görs även en undersökning av sex omtalade tingsrättsdomar för att se hur pThis essay aims to study the importance of confessions in Swedish criminal law procedure. The essay consists of a general overview of the court’s evaluation of evidence as well as an examination of how the courts perceive confessions and the strength of a confession as evidence. Six renowned district court rulings have been analyzed to see how the law is applied. Since this area is largely unregul

The world is currently facing a number of large environmental challenges, and cleantech is pointed at to be one of the best potential answers. However, in the winds of a financial crisis, shifting capital markets and rapidly growing information technology sector, the cleantech segment currently finds itself in a disadvantaged situation where the direly needed early-stage capital is not finding its

III-V nanowire transistors might provide a mean for extending Moore’s law, by overcoming the scaling limitations ultimately facing planar silicon CMOS. These high frequency capable transistors with cut-off frequencies in the terahertz regime are suitable for radio communication. In this project an active double-balanced gilbert cell mixer consisting of nanowire field-effect transistors (NWFETs) wa

Sedan urminnes tider har man vetat om att det finns ljusa kroppar på himlen som rör sig ovanligt fort. Grekerna döpte dessa till vandrare, ett ord som på grekiska uttalas väldigt likt planet. Planeterna har studerats i århundraden och bara de senaste två decennierna har vi ökat från våra egna åtta planeter till flera tusen nya planeter kallade exoplaneter, planeter runt andra stjärnor än våran egeData from NASA's Kepler space telescope, which searches for exoplanets via the transit method, produced 1108 new planetary candidates in 2013 with a total of 91% being smaller than Neptune in size. These were mostly super-Earths, terrestial planets between Earth and Neptune in size, with orbits around 10 days. In order for any theory of planet formation to be valid it must be able to account

För att dömas till straffansvar enligt svensk rätt krävs att gärningspersonen uppvisar skuld antingen i form av uppsåt eller oaktsamhet. Straffrättsligt ansvar för våldtäkt förutsätter enligt svensk rätt att gärningspersonen begår gärningen med uppsåt. I våldtäktsbrottmål kan en gärningsperson som misstar sig om en relevant omständighet och alltså begår gärningen utan uppsåt inte dömas till straffTo be held liable for a crime under Swedish law, the offender has to show guilt, either intentionally or through negligence. According to Swedish law, criminal liability for rape presupposes that the perpetrator has committed the act intentionally. In rape crime cases, an offender cannot be convicted if he or she is mistaken about a relevant circumstance and hence commits the act through negligenc

Förståelse av dynamiken i interaktionen mellan proteiner och olika molekyler kan underlätta designen av nya läkemedel mot till exempel cancer. Detta kan man studera i stora magneter med så kallad magnetresonansspektroskopi. I kroppen finns en proteinfamilj, Galektiner, som deltar i många biologiska processer. Ett av dessa protein, Galektin-3, är involverat i utvecklingen av cancer vilket gör att This master thesis consists of two parts, which both deal with NMR studies of the carbohydrate-binding domain of the protein galectin-3 (Gal3C). In the first part, 19F relaxation of two difluorinated diastereomeric ligands bound to Gal3C was analyzed with the model-free approach to extract information about the dynamics. The second part reports the assignments of the backbone amide 1H/15N resonanc

The purpose of this thesis is to examine whether active fund management gives higher risk adjusted returns in comparison to index funds. This will be done by the use of three different performance measures, Sharpe ratio, Treynor ratio, and Jensen’s Alpha, the aim is to examine 116 mutual funds in the Swedish fund market over the time period of 2016-2021. By using Ordinary Least Squares, with a dum

Since 1990, international election observers have been travelling the world to monitor and assess close to 1 500 elections in developing democracies. Although often championed as the primary tool of democracy promotion, little is still known about its immediate consequences. In this research, therefore, I explore the relationship between election observers' assessments and domestic electoral r

This paper estimates and simulates a New-Keynesian small-scale DSGE macro model. The model consists of the hybrid forms of the Phillips curve and the IS curve, and is closed with a Taylor-type feedback rule allowing partial adjustment of the monetary policy instrument. We estimate the three-equation system simultaneously on Swedish data 1995:Q1 to 2014:Q4 with the FIML estimator. The empirical par

Several strategies can be used to mitigate flood risks, many of them involves construction of embankments around threatened locations or attempts to spread the flood wave in time and space. In this thesis, the effects of a mitigation strategy called eco-flooding are studied in the catchment of Lake Mälaren. The methodology involves a hypothetical storage in the terrain used as an off-line detentio

Purpose: The main purpose of this research is to gain a better understanding of how communication messages can be created more effectively in order to increase the intention to participate in VCO schemes. Furthermore, this study seeks to investigate if and how VCO and public transportation as part of a low carbon footprint vacation could be communicated. Method: A quantitative method with an expe

Commercial finite element codes are designed with a wide variety of tools and options to suit the needs of many different applications. However, in a teaching setting this is not always desirable as the effort required to learn the software draws focus and time from the teaching of the theoretical concepts. Using fully developed solvers might also allow solving of exercises without fully understan
