Scattering of stationary waves from buried three-dimensional inhomogeneities

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

Bioaccessibility of phenolic compounds in common beans (Phaseolus vulgaris L.) after in vitro gastrointestinal digestion : A comparison of two cooking procedures

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

Fractional exhaled breath temperature in patients with asthma, chronic obstructive pulmonary disease, or systemic sclerosis compared to healthy controls

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

Facilitators and barriers associated with the implementation of a Swedish psychosocial dementia care programme in Japan : a secondary analysis of qualitative and quantitative data

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 Relationship between Third-party Countermeasures and the Security Council's Chapter vii Powers : Enforcing Obligations erga omnes in International Law

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

Expression of epithelial-mesenchymal transition-related markers and phenotypes during breast cancer progression

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

Surgical treatment of basal cell carcinoma : a case series on factors influencing the risk of an incomplete primary excision

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

Emergency Department Chest Pain Patients With or Without Ongoing Pain : Characteristics, Outcome, and Diagnostic Value of the Electrocardiogram

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

Blood flow imaging by optimal matching of computational fluid dynamics to 4D-flow data

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

N2H2 binding to the nitrogenase FeMo cluster studied by QM/MM methods

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

Carboxylation of the Ni-Me Bond in an Electron-Rich Unsymmetrical PCN Pincer Nickel Complex

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, Literature : Something to hold on to

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

FragHAR : Towards ab initio quantum-crystallographic X-ray structure refinement for polypeptides and proteins

The first ab initio aspherical structure refinement against experimental X-ray structure factors for polypeptides and proteins using a fragmentation approach to break up the protein into residues and solvent, thereby speeding up quantum-crystallographic Hirshfeld atom refinement (HAR) calculations, is described. It it found that the geometric and atomic displacement parameters from the new fragHAR
