Core-level photoelectron spectroscopy measurements have been performed of aqueous solutions of NaCl codissolved with NaClOn (n=1-4). Each species has a distinct Cl 2p electron binding energy, which can be exploited for depth-profiling experiments to study the competition between Cl-and ClOn- anions for residing in the outermost layers of the solution/vapor interface. Strongest propensity for the s
The main goal of this paper is to establish general constitutive relations for the electromagnetic fields EBAR, DBAR, BBAR, and HBAR in a time domain setting. The four basic assumptions of the medium are linearity, invariance to time translations, causality, and continuity. These four assumptions imply that the constitutive relations are convolutions of the Riemann-Stieltjes type. A review of the
C4b-binding protein (C4BP), an important inhibitor of complement activation, has a unique spider-like shape. It is composed of six to seven identical alpha-chains with or without a single beta-chain, the chains being linked by disulfide bridges in their C-terminal parts. To elucidate the structural requirements for the assembly of the alpha-chains, recombinant C4BP was expressed in HEK 293 cells.
Abstract in UndeterminedThe report is an evaluation of five years of Linnaeus-Palme exchange programme between the chemistry departments at University of Gothenburg, Sweden and University of the West Indies, Jamaica. The exchange programme gives students and teachers at the two universities the possibility to study and teach at the partner university to better understand the international implicat
A stochastic model based on a probability density function (PDF) approach was developed for the investigation of spark ignition (SI) engine knock conditions. The model is based on a two zone model, where the burned and unburned gases are described as stochastic reactors, and the movement of the turbulent flame front is expressed with a Wiebe function. Using a stochastic particle ensemble to repres
Popular Abstract in Swedish Olika former av ljus har använts i åtminstone 5000 år i medicinska sammanhang. Man har i många tidiga kulturer använt solljus för att behandla olika sjukdomar. Under det senaste århundradet har användandet av ljus introducerats i den västerländska medicinen. Nya former av ljusterapi har införts. Med utvecklingen av lasern på 1960-talet dök nya användningsområden upp. LaSome aspects on the use of light for tissue characterization and treatment of malignant tumours are discussed within this thesis. The work presented aims at improving optical techniques for tissue characterization, especially to detect malignant and pre-malignant lesions. A knowledge on the interaction between light and tissue is of utmost importance to understand and improve the various technique
Analytic expression for the exact bit error probability of the (7,5) convolutional code was discussed. Recursive systematic encodes which became especially important as component encoders in concatenated coding schemes were also studied. This technique can calculate the probability distribution of the output log-likelihood ratios of the Max-Log-MAP algorithm in analytic form.
This thesis is a study of social life, addressing issues concerning how and by what means people meet in urban public space. The main aim of this thesis is to is to investigate how certain artefacts and architectural features support the formation and temporal stabilisation of heterogeneous clusters and collectives, and thus, in order to the development of conceptual tools that can contribute to a
Pulmonary diseases are known to be largely inhomogeneous. To evaluate such inhomogeneities, we are testing an image-based method to measure gas flow in the lung regionally. Dynamic, spin-density-weighted hyperpolarized (3)He MR images performed during slow inhalation of this gas were analyzed to quantify regional inflation rate. This parameter was measured in regions of interest (ROIs) that were d
p90 ribosomal S6 kinases (RSKs) respond to various mitogen stimuli and comprise two distinct protein kinase domains. The C-terminal kinase domain (CTKD) receives signal from ERK1/2 and adopts an autoinhibitory mechanism. Here, the crystal structure of human RSK1 CTKD is reported at 2.7 Å resolution. The structure shows a standard kinase fold, with the catalytic residues in the ATP-binding cleft or
This is an exploration, in dialogue with Nikolas Rose’s conceptualization of the neurochemical self, of how people taking antidepressants through in-depth interviews make sense of their experiences of using selective serotonin reuptake inhibitors. Theneurochemical self, according to Rose, is a self understood as regulated by neurochemical processes, where how we feel is mapped onto the body, more
In this paper the Poisson bracket algebra for the open massless relativistic string in the one-space-and one-time-dimensional case is considered. In order to characterize the orbit of the system the directrix function, i.e., the orbit of one of the endpoints of the string, is used. It turns out that the Poisson bracket algebra is of a very simple form in terms of the parameters of the directrix fu
Potential doubling time (Tpot), DNA synthesis time (TS), and labelling index (LI) are fundamental growth kinetics parameters in clinical and experimental cancer research, which may be of further practical importance regarding prognosis and treatment prediction of cancer. They can be measured by bromodeoxyuridine(BrdUrd)/flow cytometry (FCM) methods, where BrdUrd, an analogue of thymidine, is incor
Prediction of the in-plane biaxial strength of paper by the Tsai-Wu failure criterion has in general proved to be in good agreement with experimental data. However, the Tsai-Wu criterion overestimates the strength in some parts of the biaxial tension region. This shortcoming can be corrected by adding a pair of cubic terms to the existing Tsai-Wu criterion. The modified Tsai-Wu criterion presented
The concepts of ‘transparency’ and ‘evidence of what works’ are key features in the implementation and success of the open public service policy. This paper explores, from the perspective of the third sector, the meaning of these concepts and how we can expect them to be operationalized. Initially, an implementation guided by evidence and transparency seems reasonable and ethical. The practical me
BACKGROUND: The objective of this study was to assess, in a large data set from Swedish Medical Health Registries, whether maternal obesity and maternal morbid obesity were associated with an increased risk for various structural birth defects. METHODS: The study population consisted of 1,049,582 infants born in Sweden from January 1, 1995, through December 31, 2007, with known maternal weight and
