The focus of this work has been to implement a generic netlist reduction engine to speed up circuit simulations. The netlist reduction techniques are further optimized for Static Random-Access Memory (SRAM), wherein we exploit the repetitive pattern of the circuit. There are many driving factors for developing a netlist reduction engine for SRAM simulations. In today's System on Chip (SoC), S
In the midst of a global shift in world politics induced by the rise of emerging powers, the outdated and unequal international financial institutions (IFIs) that were set up after World War II are increasingly being challenged and scrutinized. International actors can use IFIs in numerous ways to enhance their position in the world system. For instance, they can be used as a vehicle to launder st
There is an ongoing discussion in information retrieval research regarding the merits of subject indexing with controlled vocabularies as opposed to relying on free-text descriptions. Earlier research has compared subject headings with other metadata, such as document titles or tables of contents, to determine the relative value of subject headings as subject access points in an information search
Allting är uppbyggt av atomer, inte bara träd, djur eller bläcket i dessa bokstäver, utan även astronomiska objekt så som stjärnor och planeter. Stjärnor är i princip extremt varma och kompakta moln av atomer, som skickar ut ljus i alla riktningar. Astronomer är intresserade av vilken sammansättning av atomer som bygger upp stjärnor eftersom detta hjälper dem att förstå hur stjärnor och galaxer biStellar abundances are important for understanding the chemical evolution of galaxies and provide us with constraints on stellar evolution and supernova nucleosynthesis. To determine stellar abundances accurately, atomic data is crucial. This data is incomplete for many elements, especially in the infrared region. In particular, hyperfine structure (hfs) data in the near-infrared region is lacking
Highly glazed spaces are continuously increasing in popularity due to architectural attractiveness. However, increased use of glass often jeopardizes thermal comfort in several ways and problem of overheating is one of them. A way to face this problem is to appropriately use solar control mechanisms. However, a proper selection of solar control mechanisms from an early design stage is a complex ta
Vid marktekniska undersökningar i finkorniga jordar är det av stor vikt att korrekt kunna bestämma den odränerade skjuvhållfastheten. Detta görs idag vanligtvis ute i fält med en uppsjö av sonderingsmetoder som ger olika mått på hur fast jorden är. För homogena leror och sand finns det en stadig empirisk grund för hur dessa sonderingsparametrar räknas om till odränerad skjuvhållfasthet, men hur seThe undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt
Cationic liposome-DNA (CL-DNA) complexes, are regarded as promising materials for safe and efficient delivery of genes for therapeutical applications. In order to be used in vivo, these complexes may be coated with a hydrophilic polymer (e.g. polyethylene-glycol, PEG) that provides steric stabilization towards adhesion of proteins and removal by the immune system. In this work we study the influen
Background: B-vitamins are essential for one-carbon metabolism and have been linked to colorectal cancer. Although associations with folate have frequently been studied, studies on other plasma vitamins B2, B6, and B12 and colorectal cancer are scarce or inconclusive. Methods: We carried out a nested case-control study within the European Prospective Investigation into Cancer and Nutrition, includ
The main purpose of this thesis was to examine various factors influencing starch retrogradation. The reassociation events of starch, which are closely linked to the staling of bakery products, were mainly studied by thermal analysis. Some aspects of starch gelatinization are also included. The gelatinization and retrogradation were described as non-equilibrium processes where the phase transition
Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. The Ca2+ gradients are used by the cell to transmit information in a variety of physiol
The objective of this thesis is to propose a way to introduce social and cultural aspects of environmental degradation to the sustainable development debate. This is done by a reflexive and critical examination of environmental research as it has been applied to different spatial levels (and thus levels of social complexity). The spatial categories discussed are the city, the household and the lan
This paper presents a front-end architecture for fully integrated 60 GHz phased array receivers. It employs LO-path beamforming using a phase controlled phase-locked loop (PC-PLL). To demonstrate the architecture a circuit is implemented featuring a two stage low noise amplifier, two cascaded active mixers, and a PC-PLL. The receiver downconverts the 60 GHz signal in two steps, using LO signals fr
Vitreoscilla is an obligate aerobic bacterium found in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla induces the production of a homodimeric hemoglobin (VHb) when subjected to oxygen-limiting conditions. It is thought that VHb facilitates oxygen delivery to the respiratory apparatus of its host by increasing the local oxygen concentration under oxygen-
Popular Abstract in English Airborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes. In order to understand completely the role of aerosols in atmosphere, their chemical composition is of basic importance. Chemical analysis of aerosols involves broadly two steps, extraction step and detection/quantification of chemical constituents
The sialyl Lewis x (SLex) tetrasaccharide is the smallest recognizable ligand for selectins. The selectins constitute a vital part of the inflammatory cascade for recruitment of leukocytes to a site of tissue damage or microbial infection. If too many leukocytes are recruited, normal, not injured, cells can be damaged; a process known from chronic inflammatory diseases such as reumatoid arthritis,
The partly hot-water driven CO2 capture plant offers a significant potential for improvement in performance when implemented in a combined-cycle power plant (CCPP). It is possible to achieve the same performance with a dual-pressure steam cycle as in a triple-pressure unit. Even a single-pressure plant can attain an efficiency competitive with that achievable with a triple-pressure plant without t

A first research development progress report of the Chromosome 19 Consortium with members from Sweden, Norway, Spain, USA, China and India, a part of the Chromosome-Centric Human Proteome Project (C-HPP) global initiative is presented (http://www.c-hpp.org). From the chromosome 19 peptide-targeted library constituting 6159 peptides, a pilot study was conducted using a sub-set with 125 isotope-labe
The calcium-sensitizing Rho A/Rho kinase pathway has been suggested to play a role in the control of nongenital vascular smooth muscle. Rho-associated kinases (ROKs) cause calcium-independent modulation of smooth muscle contraction, and have been demonstrated in the bladder, prostate, and corpus cavernosum. Until now, it is not known whether ROKs and related proteins play a role in the control of
