Ground-level ozone (O3), formed via complex photochemistry involving nitrogen oxides (NOx) and volatile organic compounds (VOCs), is a critical secondary pollutant and oxidant. Therefore, understanding whether the formation of O3 is NOx- or VOC-limited is essential for effective air quality management. Recently, we demonstrated that the distribution of highly oxygenated organic molecules (HOMs) ca

Centre for Retail Research at Lund University ANNUAL REPORT | 2021 2 ANNUAL REPORT CENTRE FOR RETAIL RESEARCH AT LUND UNIVERSITY 2021 Introduction Centre for Retail Research – the eighth year For us, just as many others, 2021 was yet another special year. The coronavirus has challenged us in many ways. However, this year we were somewhat better prepared and well-versed in finding online solutions

We show that the undular stray light, diffusely scattered by the optical system of a synchrotron beamline, can play an important role in the formation of high-resolution resonant photoelectron (RPE) spectra. The influence of the stray light is mediated through the Stokes doubling effect, with the Lorentzian tail of the spectral function being replaced by a more complicated form. This effect is sho

Excited states of the neutron deficient Ag-101 nucleus have been investigated via the Cr-50(Ni-58, 3rho1alpha) heavy-ion induced reaction at 261 meV by use of in-beam spectroscopic methods. On the basis of the measured gammagamma-cincidence relations and angular distribution ratios high-spin bands have been extended up to I-pi = 35/2(+), 45/2((-)) and (49/2(-)). The negative parity states at the h

The book contains editions and studies of texts produced by Swedish academics active at the University of Leipzig in the fifteenth century. Academic texts from the Middle Ages are difficult to digest; the editions, translations and studies presented in this book and its companion volumes make them as accessible to the modern reader as one can possibly ask.

Crises narratives surrounding the societal challenges of biodiversity loss, climate change, and human health and well-being dominate current debates in global environmental politics. These challenges are deeply interconnected and require transformative and integrated change. Marine and coastal Nature-based Solutions (blue NbS) are an opportunity to minimise harmful human impacts on these ecosystem

This paper investigates a behavioral-feedback SIR model in which the infection rate adapts dynamically based on the fractions of susceptible and infected individuals. We introduce an invariant of motion and we characterize the peak of infection. We further examine the system under a threshold constraint on the infection level. Based on this analysis, we formulate an optimal control problem to keep

Background & Aims Microscopic colitis (MC) is a leading cause of chronic diarrhea, particularly in older adults. Although many patients respond to budesonide, refractory and dependent cases pose major therapeutic challenges. Although the off-label use of advanced inflammatory bowel disease therapies is expanding, robust real-world data remain scarce. Methods Through the ECCO CONFER network, we

Lactic acid bacteria (LAB), including Lactococcus lactis, are abundant in nature. These bacteria convert carbohydrates into mainly lactate by a rather uncomplicated metabolism. An improved understanding of the physiological and genetical mechanisms involved in carbohydrate metabolism and its regulation will improve the industrial use of LAB. The aim of this study was to investigate the maltose an

There are many benefits offered by integrated enterprise computer systems. There are a growing number of options available to obtain such management information system support. A major problem when selecting Enterprise Information Systems, in special ERP systems, is how to deal with the great diversity of options as well as the number of criteria used to evaluate each alternative. There is an impl

Popular Abstract in Swedish I litteraturen kring marknadsföring av tjänster har det i flera sammanhang diskuterats hur tjänster baserade på kombinationer av kundmedverkan och teknologi kan erbjudas till kunden. Exempel som behandlats är bankers uttagsautomater, självbetjäning på bensinstationer och automatiska banktjänster över telefon. Innan man kan presentera sådana rekommendationer behövs det gThis doctoral thesis deals with consumers’ attitudes towards serving them-selves with machines rather than being served by personnel. Its aim is to contribute to the theory of perceived service quality by providing a better understanding of customers’ attitudes and preferences when using technology-based self-service. In addition to aspects of service dealt with by traditional service-quality rese

Objective: The prognostic influence of neuroendocrine (NE) differentiation in prostate cancer patients is not yet properly established. In a series of primary hormone-naive prostate cancers from a patient population that underwent radical prostatectomy, we wanted to determine the relationship between NE phenotype expression and Gleason sum, disease stage, and serum PSA concentration. Methods: Ch

Popular Abstract in Swedish Mycken möda har under de senaste årtiondena lagts ner på forskning om försurande utsläpp och dess skadliga effekter på skogar, vattendrag och människor. Kritiska belastningsgränser, i folkmun kallat "vad naturen tål", har tagits fram och använts i europeiska förhandlingar om utsläppbegränsningar. För skogsekosystem baseras de kritiska belastningsgränserna för försurandeAcidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.g. for Swede

Excited states in (196)AU, populated in the Pt-196(p,n) and (d,2n) reactions, were investigated by in-beam gamma -ray and conversion-electron spectroscopy. Two only weakly connected level structures, built on the 2(-) ground state (negative-parity level scheme) and on the 5(+) isomer at 84.7 keV (positive-parity level scheme), are observed. The point of main effort of the present work was the inve

Excessive sweating is a major ergonomic concern in bicycle helmet use and low wearing rates are suspected to originate, at least partly, from impaired thermal comfort due to accumulated sweat increasing skin wettedness at the head region. As a development from COST Action TU1101 WG4, we introduce a modelling framework for assessing the thermal comfort of bicy-cle helmet use. We predicted local swe

Popular Abstract in Swedish Fantasygenrens många främmande och fantastiska platser ger inte bara handlingen en exotisk kuliss utan är tätt knutna till hur berättelserna är uppbyggda. I Stefan Ekmans doktorsavhandling Writing Worlds, Reading Landscapes: An Exploration of Settings in Fantasy visas hur miljön i fantasy är lika viktig som persongalleriet och intrigen. Fantasy är en genre som sätter väIn fantasy literature, the setting is as important to the story as are characters and plot; but although many fantasy scholars have pointed this out, there is very little criticism that explores the role of the setting in fantasy. The aim of this study is to use a topofocal (place-focused) perspective to examine four aspects of the fantasy setting, including the way in which settings function in t
