A new criterion is applied for characterization of the kinetic design of enzymes that should be favoured by a selective pressure in the direction of increased metabolic reaction flux. According to this criterion, the selectively favoured state of a metabolic sequence of enzyme reactions conforming to Michaelis-Menten kinetics is identical with the uniform one which is known to optimize reaction fl
This paper presents a 1MHz bandwidth, ΔƩ fractional-N PLL as the frequency synthesizer for LTE. A noise cancellation path composed of a novel hybrid ΔƩ DAC with 9 output bits is incorporated into the PLL in order to cancel the out-of-band phase noise caused by the quantization error. Further, a re-timing circuit is proposed to reduce the nonlinearity in the Charge Pump and provide pulse shaping si
Our main purpose with this study is to examine and elucidate the recovery process that occurs when women choose to break up from destructive relationships. Our aim is also to clarify what, by the women themselves, is considered to be efficient help in relation to what in fact is offered in actuality. The idea of this selection was that we, in the study of the recovery process, would make a compili
The semiconductor industry is one of the most technologically advanced and complex industries in the world, not only because of the extreme development pace, but also because of the necessary production processes to create the finished product. The value increase from silicon as raw material, to integrated circuits (IC), is equivalent to the transformation of sand into a product worth more than it
Backgrund Product development (PD) in the plant breeding industry is characterized by long development cycles and decisions framed with uncertainty concerning key questions such as likely future competitor actions or the market outlook 10-15 years from now. In many ways the contemporary picture of the industry is changing rapidly; new technologies are developed to shorten the length of PD cycles a
This master thesis was conducted at Volvo Car Corporation, VCC, in Gothenburg within the Manufacturing Engineering department. It is based on the P11-project (the new model S40) where the process verification has been examined and analyzed. The purpose of the thesis is to investigate the reasons behind remaining and new problems at late stages in the development process, as well as possibilities f
This study investigates the impact of a 10-week Arts on Prescription (AoP) program in Denmark designed for young adults aged 18–30 who were disengaged from education and unemployed. Eighteen participants took part in four semi-structured focus group interviews, and four completed a survey; most reported experiences of anxiety, depression, and stress, with some describing chronic pain, ADHD, or aut
Problem formulation: Traditional accounting and financial reports do not provide sufficient information today. New reports like the Intellectual Capital Statements are one answer to this problem. They systematically report on Intangible Assets that create value in the company. We found that external stakeholders do not use Intellectual Capital Statements in their evaluation processes. This made us
This article focuses on the ways in which women employed in Vietnam’s heavy industry, mitigate and cope with crises at the workplace and in social life. Drawing on ethnographic fieldwork, which I have conducted in the Industrial Zones of northern Vietnam in the international corporations called Xylan and Yate, I examine how women who are working on the floor manage crises entanglements as an unde
In nuclear medicine, radiopharmaceuticals can be administered for both diagnostic and therapeutic purposes. In recent years, there has been an increasing interest in theragnostics, a strategy that combines both diagnosis and therapy. This can be achieved by using similar radiopharmaceuticals for imaging and radionuclide therapy, which enables highly personalised disease management. One theragnosti
Ever-increasing global water shortages necessitate more advanced and cost-effective water purification methods. Herein, a novel slow filtration system using natural raw zeolite is proposed as an alternative to traditional quartz sand as a filter medium. The system demonstrates excellent performance in reducing turbidity and removing methylene blue (MB). The natural zeolite-based filtration system
Popular Abstract in Swedish Syftet med denna avhandling är att utforska fenomenet vetenskapligt kritiskt tänkande, när det gäller dess olika innebörder, villkor och utveckling. Kritiskt tänkande studeras genom att analysera olika filosofiska och pedagogiska texter, utifrån ett hermeneutiskt-fenomenologiskt perspektiv. Avhandlingen som är skriven på engelska erbjuder läsaren en inblick i hur min egThe purpose of this thesis is to explore the phenomenon of critical thinking in scholarship as regards its meanings, conditions, and development using a hermeneutic-phenomenological approach. This exploration takes its departure in ancient Greece, following a historical movement of the phenomenon up to present day perspectives on critical thinking, revealing a range of different meanings and condi
Laterally grown InxGa1-xAs nanowires (NWs) are promising candidates for radio frequency and quantum computing applications, which, however, can require atomic scale surface and interface control. This is challenging to obtain, not least due to ambient air exposure between fabrication steps, which induces surface oxidation. The geometric and electronic surface structures of InxGa1-xAs NWs and conta
The aim of this work is to develop a method for detection of brief episode paroxysmal atrial fibrillation (PAF). The proposed method utilizes four different features: RR interval irregularity, absence of P waves, presence of f-waves and noise level. The obtained features are applied to the Mamdani-type fuzzy inference method for decisionmaking. The performance was evaluated on one hundred 90 s lon
The Arctic is warming at twice the global average speed, and the warming-induced increases in biogenic volatile organic compounds (BVOCs) emissions from Arctic plants are expected to be drastic. The current global models' estimations of minimal BVOC emissions from the Arctic are based on very few observations and have been challenged increasingly by field data. This study applied a dynamic ecosyst
This paper deals with the enactment of power in and through a sharing economy business model. The objective of research is to understand business models as a kind of narrative performance that mobilise labour, capital and users on a startup platform within adventure tourism. The paper elaborate on the dynamics between performances and power in terms of how the narratives performed by the platform
Class Ib ribonucleotide reductases (RNR) utilize a di-nuclear manganese or iron cofactor for reduction of superoxide or molecular oxygen, respectively. This generates a stable tyrosyl radical (Y·) in the R2 subunit (NrdF), which is further used for ribonucleotide reduction in the R1 subunit of RNR. Here, we report high-resolution crystal structures of Bacillus anthracis NrdF in the metal-free form
We study the process gg → bb̄H+H- at large tanβ, where it represents the dominant production mode of charged Higgs boson pairs in a Type II 2-Higgs doublet model, including the minimal supersymmetric standard model. The ability to select this signal would in principle enable the measurements of some triple-Higgs couplings, which in turn would help understanding the structure of the extended Higgs
