Aromatic amino acids play an important role in ultraviolet (UV)-induced photochemical reactions in proteins. In this work, we aim at gaining insight into the photochemical reactions induced by near-UV light excitation of aromatic residues that lead to breakage of disulfide bridges in our model enzyme, Fusarium solani pisi cutinase, a lipolytic enzyme. With this purpose, we acquired transient absor

The European Union boasts free movement of workers as one of its fundamental freedoms for all citizens. However, this freedom does not exist free from controversy or challenging issues. Professional workers raise unique problems when considering the exercise of this freedom. Member States in which the professionals wish to practice are reasonably concerned with assuring that the professionals prac

Today’s supply chains have become more global than ever before, which has brought out an enormous increase in environmental damage such as CO2 emissions. In an initiative to become more environmentally friendly, Swedish Food Federation has launched a joint sustainability manifest. 41 food producers in Sweden have joined this initiative and The Company is one of them. The manifest consists of five

We show that conformational entropies calculated for five proteins and protein-ligand complexes with dihedral-distribution histogramming, the von Mises approach, or quasi-harmonic analysis do not converge to any useful precision even if molecular dynamics (MD) simulations of 380-500 ns length are employed (the uncertainty is 12-89 kJ mol(-1)). To explain this, we suggest a simple protein model inv

Några av de stora mysterierna inom fysik idag handlar om vad mörk materia egentligen är och varför det finns så mycket mer materia än antimateria i universum. Två av de planerade instrumenten vid ESS i Lund, HIBEAM och NNBAR, har som mål att försöka besvara dessa frågor genom att studera hypotetiska fria neutronoscillationer. I detta arbete har optiska guidesystem för neutroner på HIBEAMs strålstrIn this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe. This will be

Popular Abstract in Swedish Vid extern strålbehandling används en s.k. linjäraccelerator för att producera och leverera den önskade strålningen till cancertumörer. I linjäracceleratorn accelereras elektroner till nära ljusets hastighet och styrs sedan mot en metalplatta där de bromsas upp och genererar bromsstrålningsfotoner (högenergetisk röntgenstrålning). Intensiteten av den strålning som sändsThe aim of this work was to investigate the dosimetric effects of removing the flattening filter from conventional C-arm medical linear accelerators. In conventional linear accelerators used for radiotherapy, a flattening filter is positioned in the beam line to provide a uniform lateral dose profile at a specified depth in water. However, for some radiotherapy treatments, a uniform lateral dose p

BACKGROUND: Patients with severe aortic stenosis (AS) often have coronary artery disease. Both the aortic valve and the coronary disease influence the blood flow to the myocardium and its ability to respond to stress; leading to exertional symptoms. In this study, we aim to quantify the effect of severe AS on the coronary microcirculation and determine if this is influenced by any concomitant coro

ConclusionsPaper I: Complications in Extracorporeal Shock Wave Lithotripsy (ESWL): A cohort study, conclusion: We conclude that there are few complications to modern ESWL treatment. 1 Hz should be used to reduce complications (p=0.025). As there is no indication that 1Hz is less effective than 1.5 Hz, this strongly implies that 1 Hz should normally be the frequency used.Success rate with ESWL alon

Background: Dietary carbohydrates are a major source of energy in the Nordic and Baltic countries. The health effects of different types of carbohydrates vary and there is a need to update the evidence regarding specific carbohydrates and their effects on health-related outcomes. Objective: The aim of this scoping review was to describe the evidence for the role of total carbohydrates (fiber exclu

In order for your publications to be made freely accessible in LUCRIS you need to own the copyright to them. Presented below are a few copyright-related starting points based on a rough classification of different types of publications. The purpose of copyright law is to balance the author’s protection needs against the user’s access needs. Therefore, the law is combined with reasonable exceptions

Several research studies have shown the importance of physical exercise. The global gym and fitness industry faced a transition from traditional gyms to virtual fitness training during the pandemic lockdowns. A proliferation of applications is available to provide different digital gym experiences. Advagym is one example that uses sensors to track and give feedback to gym goers. Sony's R&D Cen

Adsorption onto chromium surfaces during heat treatment (65–68°C) of β-lactoglobulin A and B in phosphate buffer, pH 6.88, was investigated byin situellipsometry. Thermal unfolding andin situheat-induced aggregation under the same conditions were studied by differential scanning calorimetry and dynamic light scattering, respectively. A lag phase was observed for buildup of the thickness of the

Formation of metal hydrides is a serious complication that occur when hydride forming metals such as zirconium, niobium, vanadium and magnesium are exposed to long term hydrogen environment. The main concern is that the hydride, as being a brittle material, has very poor fracture mechanical properties. Formation of hydride is associated with transportation of hydrogen along the gradients of increa

The physical origin of sub-band gap photoluminescence in Ruddlesden-Poppers two-dimensional (2D) lead halide perovskites (LHPs) is still under debate. In this paper, we studied the photoluminescence features from two different facets of 2D LHP single crystals: the in-plane facet (IF) containing the 2D inorganic layers and the facet perpendicular to the 2D layers (PF). At the IF, the free carriers

Cell-Free networking is one of the prime candidatesfor 6G networks. Despite being capable of providing the 6Gneeds, practical limitations and considerations are often neglectedin current research. In this work, we introduce the conceptof federations to dynamically scale and select the best set ofresources, e.g., antennas, computing and data resources, to servea given application. Next to communica

The formation of polar nanoregions through solid-solution additions is known to enhance significantly the functional properties of ferroelectric materials. Despite considerable progress in characterizing the microscopic behavior of polar nanoregions (PNR), understanding their real-space atomic structure and dynamics of their formation remains a considerable challenge. Here, using the method of dyn

In this work, we present Monte Carlo simulations of mixtures containing negatively charged latex particles and positively charged dendrimers. We focus on the interaction between two latex particles as salt concentration, dendrimer dose, and generation number are varied. Interaction free energies and corresponding stability ratios are calculated. Minimal stability is found near the isoelectric poin

Nigella damascena seeds were extracted by cold press, in a Soxhlet apparatus and with CO2 The yield obtained with liquid CO2 was only 10.57%. EtOH (1%) increased the yield by 50%. CO2-extracts were separated into the 2 fractions. The yield in the first fraction increased 2 times by increasing the pressure from 150 to 350 bar. EtOH (1%) increased the yield 2 times at 150 bar. Linoleic acid was the
