I detta arbete kommer vi att visa några entydighetssatser för Helmholtz' ekvation. Området begränsas av en yta S som är oändlig. Främst kommer satser som visar entydigheten hos material med förluster att tas fram, men för vissa speciella ytor S kan även rent förlustfria medier behandlas.Randvillkoren kommer att vara av Churchills typ eller mot svarande för permeabla medier. Som ett led i beviskedj
A previously developed formalism for calculation of the scattering from a buried inhomogeneity is taken as a starting point for an iterative scheme for treating the influence of a deviation from a flat interface. This deviation can be a hill, or a depression, of finite extent on an otherwise flat surface. Each iteration takes into account all the multiple interactions between the hill and the inho
The T matrix method (also called the "extended boundary condi tion method" or "null field approach") introduced by Waterman, has recently been generalized to interfaces of infinite extent (G. Kristensson and S. Strom, J. Acoust. Soc. Am. 64917936 (1978) and G. Kristensson, Electromagnetic Scattering from Buried Inhomogeneities - a General Three Dimensional Formalism", Rep. 78-42, Inst. of Theoreti
The T-matrix method (also called the "extended boundary condition method" or "null field approach") is a formalism, which applies to scattering of linear classical waves (i.e. acoustic, electromagnetic and elastic waves). The object of this thesis is to extend the T-Matrix formalism to a geometry consisting of twohalf-spaces, one of which contains a three-dimensional inhomogeneity. The two half-sp
Background and objectives: Beans (Phaseolus vulgaris L.) are widely consumed, but the bioaccessibility of their phenolic compounds (PCs) may be affected by different factors. Within this framework, an in vitro gastrointestinal digestion of two bean varieties: “Azufrado” and “Negro Jamapa,” was performed and the bioaccessibility and in vitro release kinetics of PC was evaluated. Mashed beans were p
Exhaled breath temperature has been suggested to reflect airway inflammation, and it would be plausible to measure the peripheral airway temperature as a correlate to peripheral airway inflammation. This study aims to explore the relative peripheral airway temperature in patients with asthma, chronic obstructive pulmonary disease (COPD) or systemic sclerosis (SSc) compared to healthy controls, and
Background: A psychosocial dementia care programme for challenging behaviour (DEMBASE®) was developed in collaboration with a Swedish BPSD-registry team for in-home care services use in Japan. The programme consisted of a web-based tool for the continued assessment of challenging behaviours and interdisciplinary discussion meetings. Effectiveness of the adapted programme was verified through a clu
The article examines the relationship between third-party countermeasures and the Security Council's powers to adopt measures under Chapter vii of the United Nations Charter in response to breaches of obligations erga omnes. It is shown that the resort to third-party countermeasures is neither precluded nor subject to limitations as a result of the relationship to the Security Council's Chapter vi
Purpose: The study aimed to investigate expression of epithelial-to-mesenchymal transition (EMT)-related proteins and phenotypes during breast cancer progression and to relate this to patient outcome. Methods: Protein expression patterns of E-cadherin, N-cadherin, twist, and vimentin were examined by immunohistochemistry on formalin-fixed paraffin-embedded samples from primary tumors (PTs) (n = 41
Background: Basal cell carcinoma (BCC) is the most common skin cancer form, and one first-line treatment is surgical excision. Complete excision is vital to minimize risk of recurrence. Studies on occurrence of incomplete excisions have given diverse results and seldom include large populations from a dermatological setting. Objectives: The rate of positive surgical margins in primary surgery of B
Background: In emergency department (ED) chest pain patients, it is believed that the diagnostic accuracy of the electrocardiogram (ECG) for acute coronary syndrome (ACS) is higher during ongoing than abated chest pain. Objectives: We compared patient characteristics and the diagnostic performance of the ECG in ED patients presenting with ongoing, vs. abated, chest pain. Methods: In total, 1132 un
Purpose: Three-dimensional, time-resolved blood flow measurement (4D-flow) is a powerful research and clinical tool, but improved resolution and scan times are needed. Therefore, this study aims to (1) present a postprocessing framework for optimization-driven simulation-based flow imaging, called 4D-flow High-resolution Imaging with a priori Knowledge Incorporating the Navier-Stokes equations and
We have made a systematic combined quantum mechanical and molecular mechanical (QM/MM) investigation of possible structures of the N2 bound state of nitrogenase. We assume that N2 is immediately protonated to a N2H2 state, thereby avoiding the problem of determining the position of the protons in the cluster. We have systematically studied both end-on and side-on structures, as well as both HNNH a
The synthesis of a new unsymmetrical PCN ligand bearing tert-butyl groups on the phosphorus atom and isopropyl groups on the nitrogen donor atom is presented. It reacts with the commercially available Ni(DME)Br2 precursor to offer the corresponding t-BuPCNi-Pr pincer nickel bromide complex 1 together with a paramagnetic species, which was characterized as a tetrahedral nickel complex. Complex 1 re
Memory, Intermediality, and Literature investigates how selected literary works use intermedial strategies to represent and perform cultural memory. Drawing on the theoretical perspectives of cultural memory studies, this engaging, reader-friendly monograph examines new materialism and intermediality studies, analyzying works by Alexander Kluge, W.G. Sebald, Jonathan Safran Foer, Anne Carson, Mett
