Theoretical and empirical studies have shown that species radiations are facilitated when a trait under divergent natural selection is also involved in sexual selection. It is yet unclear how quick and effective radiations are where assortative mating is unrelated to the ecological environment and primarily results from sexual selection. We address this question using sympatric grasshopper species
Contaminated ground is a severe problem which is present in many countries, and it is of great importance to find efficient solutions to deal with it. In Sweden, there is a trend in the industry to move towards alternate remediation methods and on that scope in-situ bioremediation has received a lot of attention. The main challenge with in-situ bioremediation is to verify that the treatment has th
The PreProcessor of the ATLAS Level-1 Calorimeter Trigger prepares the analogue trigger signals sent from the ATLAS calorimeters by digitising, synchronising, and calibrating them to reconstruct transverse energy deposits, which are then used in further processing to identify event features. During the first long shutdown of the LHC from 2013 to 2014, the central components of the PreProcessor, th
The PHENIX experiment has measured the spin alignment for inclusive J/ψ→e+e- decays in proton-proton collisions at s=510 GeV at midrapidity. The angular distributions have been measured in three different polarization frames, and the three decay angular coefficients have been extracted in a full two-dimensional analysis. Previously, PHENIX saw large longitudinal net polarization at forward rapidit
The ammonia oxidation reaction over a PtRh binary alloy has been studied with a surface science approach by operando techniques such as near-ambient pressure X-ray photoemission spectroscopy (NAP-XPS) and surface X-ray diffraction (SXRD) combined with mass spectrometry. The article will explore the surface evolution across five different oxygen to ammonia ratios in the millibar regime for two diff
This chapter briefly reviews how bibliometric indicators are used for allocating resources in academia. How these measures can be understood in relation to different evaluation systems is discussed, and various types of applications - including individual level use - are outlined. Furthermore, attention is given to the effect of evaluation in terms of incentives and possible adverse effects. The i
Introduction: due to increasing coverage of antiretroviral therapy (ART), more women living with HIV have improved health condition which also increases their chances of getting pregnant. However, the knowledge about pregnancy among women receiving ART in resource-constrained settings, like Ethiopia, is limited. The aim was to assess factors associated with pregnancy among women living with HIV in
The digital transformation of the retailing industry in recent years has had a profound effect on consumers’ behaviour on a global scale. When shopping and browsing online, consumers are not able to “touch and feel”, which means that product returns are inevitable. The fashion industry has particularly suffered from high return rates, which fluctuate between 30% and 50%. The industry has been stru
Solen har lyst konstant på vår värld i fyra och en halv miljard år. Strålarna som värmer vår hud idag har känts av varenda person som någonsin levt. Solens strålar har rört vid dinosaurier, och hälsat på de första varelser som lämnade havens vatten för ett liv på land.Solen har varit vittne till allting som skett här på Jorden. Men den är ingen passiv iakttagare. Solen är vår planets kraftverk, deThe Sun has shone on our world for four and a half billion years. The light that warms our skin today has been felt by every person who has ever lived.It is our nearest star and our planet’s powerhouse, the source of the energy that drives our winds, our weather and all life.The passage of the Sun’s fiery disc across the sky — day by day, month by month — was the only way to keep track of time for
The demand for better methods for condition control and monitoring of embankment dams will increase in a near future as a result of expected more extreme weather situations. Furthermore the availability demand on hydropower will increase as a result of switching from fossil fuels to wind and solar power, in some countries in combination with decommissioning of nuclear power. Temperature monitoring
The current range and volume of research evaluation-related literature is extensive and incorporates scholarly and policy/practice-related perspectives. This reflects academic and practical interest over many decades and trails the changing funding and reputational modalities for universities, namely increased selectivity applied to institutional research funding streams and the perceived importan
In order to electrify commercial distribution vehicles, an easy to use charging infrastructure with minimum driver interaction is needed, as managing time is essential to maximize profit for this type of vehicles. This paper proposes the use of a piece of a conductive Alternating Short-Segmented Electric Road System (ASSE) as an automatic charger for lightweight distribution vans. Since the ASSE i
Background: Middle Eastern immigrants to Europe represent a high risk population for type 2 diabetes. We compared prevalence of novel subgroups and assessed risk of diabetic macro- and microvascular complications between diabetes patients of Middle Eastern and European origin. Methods: This study included newly diagnosed diabetes patients born in Sweden (N = 10641) or Iraq (N = 286), previously in
Aims and objectives: To obtain the current perception of the knowledge and competence of pre-hospital emergency specialist nurses (ambulance) in attending patients with psychiatric symptoms. Background: Psychiatric illnesses have increased throughout the population. Consequently, pre-hospital emergency services frequently attend individuals with suspected or known mental illnesses. Design: We empl
Context: White matter lesions (WML) are caused by obstruction of small cerebral vessels associated with stroke risk. Craniopharyngioma (CP) patients suffer from increased cerebrovascular mortality. Objective: To investigate the effect of reduced HT volume and cranial radiotherapy (CRT) on WML in childhood-onset CP patients. Design: A cross-sectional study of 41 patients (24 women) surgically treat
Background: Fragrances are the most common cause of cosmetic contact allergy. Up-to-date information on contact allergy frequencies and relevance aids primary and secondary preventive measures. Objectives: To determine the prevalence, associated factors, and concomitant reactions in fragrance allergy among Thais. Methods: This retrospective study collected data from 2012 to 2019. The patient chara
Lund presenteras som en medeltidsstad, och visst har staden sitt ursprung i medeltiden, men periodbeteckningen är en eftermedeltida konstruktion och de bevarade spåren är färre än man kan förledas tro. I artikeln genomgås vad som finns kvar av från medeltiden – domkyrkan, Liberiet, Klosterkyrkan, ruinen av sockenkyrkorna Maria Minor och Drotten, Krognoshuset, Dekan- och Kanikresidenset, stadsvalleLund in Scania is perceived as a medieval town. It has its origin in the Middle Ages for sure, however the concept of such a period is a later invention and the preserved traces are fewer and more transformed than one might believe. The article presents what remains from the Middle Ages – the cathedral, the nearby library, the monastery of S:t Peter and Mary, the moved ruins of the parish church M
Denna vägledning vänder sig till personer som behöver tips och idéer på hur man kan sammanställa sina samverkansmeriter. Målgruppen är i första hand lärare och forskare vid svenska universitet och högskolor. Vägledningen baseras på erfarenheter från det praxisnära arbetet som har utförts inom projektet MerSam – Meritvärde av samverkansskicklighet (2018–2020).1 I MerSam har elva svenska lärosäten d
Type 1 diabetes (T1D) and celiac disease (CD) share common genetic loci, mainly within the human leukocyte antigen (HLA) class II complex. Extended genotyping of HLA class II alleles and their potential risk for developing both diseases remains to be studied. The present study compared extended HLA-class II gene polymorphisms in children with T1D, CD, and a subgroup diagnosed with both diseases (T
