In recent years, the awareness of potential radiation damage of metal centers in protein crystals during crystallographic data collection has received increasing attention. The radiation damage can lead to radiation-induced changes and reduction of the metal sites. One of the research fields where these concerns have been comprehensively addressed is the study of the reaction intermediates of the

An NMR technique to measure exchange kinetics at thermal equilibrium in dispersions of moderately soluble crystalline material is presented. By monitoring the exchange of molecules between pools in solid and dissolved form, one can characterize the surface specific exchange rate. Illustrative experiments were performed in a model system with b-type crystals of tripalmitin as the solid phase and tr

Ptychography has evolved as an important method for nanoscale X-ray imaging with synchrotron radiation. Recently, it has been proposed to work with multiple beams in parallel. The main advantage of so-called multi-beam ptychography is that larger areas can be imaged much faster than with a conventional single beam scan. We introduce adaptive multi-beam ptychography performed with two Fresnel zone

Background: Expiratory flow limitation (EFL) during tidal breathing and lung hyperinflation have been identified as major decisive factors for disease status, prognosis and response to therapy in obstructive lung diseases. Aim: To investigate the delta values between expiratory and inspiratory resistance and reactance, measured using respiratory oscillometry and its correlation with air trapping a

Inom det nordisk-baltiska projektet SPEDUCULT skickades det ut en enkät till personer och verksamheter som arbetar med multisensoriska miljöer/sinnesrum i Sverige. De som svarade arbetade huvudsakligen inom verksamheter för personer med intellektuell funktionsnedsättning, såsom särskilda centra för sinnesstimulering, daglig verksamhet, habilitering eller skola. Svaren kom från 27 olika orter i Sve

Peace negotiations and their outcomes have long-term repercussions for post-conflict politics and societies. Yet, one of the most striking patterns of contemporary peace diplomacy is the gross underrepresentation of women at the negotiation table, which reflects the gendered nature of diplomacy as an institution. The research question raised in this chapter concern how gender impacts peace negotia

Purpose: Prostate specific antigen (PSA) exists in the serum in several molecular forms that can be measured by immunodetectable assays: free PSA, PSA complexed to alpha 1-antichymotrypsin (complexed PSA) and total PSA, which represents the sum of the free and complexed forms. We determined the normal distribution of values and established the appropriate reference ranges for these 3 molecular for

The formation of TiO2 films on clean and pre-oxidized Si(1 1 1) through chemical vapor deposition of titanium(IV) isopropoxide (TTIP) in ultra-high vacuum has been examined by synchrotron radiation photoelectron spectroscopy, X-ray absorption spectroscopy (XAS) and scanning tunneling microscopy. In both cases, TTIP deposition at 500 °C eventually results in an anatase TiO2 film with a carbon-free

Eugenics and race played significant roles in Ukrainian interwar nationalism, yet remain largely unstudied. The Ukrainian nationalists’ understanding of the racial makeup of their imagined community was contradictory as they struggled to reconcile their desire for racial “purity” with the realities of significant variations between the populations inhabiting the enormous territories which they sou

Popular Abstract in Swedish Många människor tillbringar en stor del av dygnet på en arbetsplats, vilket innebär att det är en plats och en tid inte bara för arbete utan också för sociala relationer samt för mat och dryck. Maten, vare sig det handlar om lunchen klockan tolv, eftermiddagsfikan klockan tre eller chokladbiten under nattskiftet, bidrar till att skapa pauser i arbetet. Arbetsplatsen kanMany people spend hours in a workplace every week and food and drink play a central role in providing nutrition and energy and help to create breaks during the working day. However, meals are something more than the food consumed. This dissertation focuses on the meal at work, where the meal is surrounded by special circumstances when it comes to time, place and social relations, as well as the fo

We report on measurements of the light absorption efficiency of InSb nanowires. The absorbed 70 fs light pulse generates carriers, which equilibrate with the lattice via electron-phonon coupling. The increase in lattice temperature is manifested as a strain that can be measured with X-ray diffraction. The diffracted X-ray signal from the excited sample was measured using a streak camera. The amoun

Popular Abstract in Swedish Arbetsplatsens positiva sidor kan förbättras genom ett nytt dialogverktyg! Nu går det att mäta medarbetares positiva upplevelser av arbete. Vanligtvis kopplas människors upplevelser av arbete samman med stress och ohälsa. Men det går att tänka tvärtom, att istället fokusera på allt det positiva som arbete kan ge. När människor mår bra av sitt arbete, blir de också mer The aim of this thesis was to develop and make a quality assessment of a tool, which includes a questionnaire and a dialogue process that could be useful for workplace health promotion from a salutogenic point of view. The studies have been performed within two health care organizations between 2005 and 2009, together with hospital staff. Two questionnaire studies were conducted (n=446 n=505, resp

Popular Abstract in Swedish Lars Ahlin har en central position i den svenska litteraturen. I forskningen framträder bilden av hans författarskap som ett litterärt projekt präglat av en jämlikhetsvision, ett motstånd mot språkliga, existentiella och politiska hierarkier. Det ahlinska berättandet är ett sällsynt gott exempel på hur ett litterärt projekt också kan vara etiskt bestämt. Detta samband bAs my title indicates, this dissertation is oriented towards two academic subjects: Ethics and Literature. Of late, the borderland between these two disciplines has attracted international scholarly attention. Within ethics, literary works are becoming a primary material; conversely, the study of literature has taken on ethical issues. As a result, the potentially referential character of fiction

The fact that the debate concerning copyright in a digital society has been both intense and filled with polemic conflicts ever since the late 1990s makes it clear that it is a most complicated issue to solve, or even grasp. Basically, both the legal and societal discussion and development are explicitly dependent on a greater understanding of the on-going processes surrounding copyright. This pre

Large scale, homogeneous quasi-free standing monolayer graphene is obtained on cubic silicon carbide, i.e., the 3C-SiC(111) surface, which represents an appealing and cost effective platform for graphene growth. The quasi-free monolayer is produced by intercalation of hydrogen under the interfacial, (6 root 3 x 6 root 3)R30 degrees-reconstructed carbon layer. After intercalation, angle resolved ph

We consider the problem of approximating a given function in two dimensions by a sum of exponential functions, with complex-valued exponents and coefficients. In contrast to Fourier representations where the exponentials are fixed, we consider the nonlinear problem of choosing both the exponents and coefficients. In this way we obtain accurate approximations with only few terms. Our approach is bu
