Timing of return to the breeding area presumably optimizes breeding output in migrants. How timing affects the other components of fitness — survival, has been comparatively little studied. Returning too early in spring is expected to be associated with high mortality in insectivorous migrants when weather conditions are still unsuitable. Yet, males in particular arrive early to get access to the
Membrane-bound water channels known as aquaporins (AQPs) facilitate water transport across biological membranes along osmotic gradients. Since all living cells depend on their ability to maintain water homeostasis, this must be tightly regulated. In eukaryotes, this is achieved by gating, which involves a conformational change of the protein, thereby physically blocking water transport, or by traf
Nitrogenase is the only enzyme that can convert N2 into NH3. The reaction requires the addition of eight electrons and protons to the enzyme and the mechanism is normally described by nine states, E0–E8, differing in the number of added electrons. Experimentally, it is known that three or four electrons need to be added before the enzyme can bind N2. We have used combined quantum mechanical and mo
Wild waterfowl are important reservoir hosts for influenza A virus (IAV) and a potential source of spillover infections in other hosts, including poultry and swine. The emergence of highly pathogenic avian influenza (HPAI) viruses, such as H5N1 and H5N8, and subsequent spread along migratory flyways prompted the initiation of several programs in Europe, North America, and Africa to monitor circula
Background: To determine the feasibility and efficacy of a retinal telephotocoagulation treatment plan for diabetic macular edema. Methods: Prospective, interventional cohort study at two clinical sites. Sixteen eyes of ten subjects with diabetic macular edema underwent navigated focal laser photocoagulation using a novel teleretinal treatment plan. Clinic 1 (King Khaled Eye Specialist Hospital, R
Objective: To identify reliable predictors of outcome in comatose patients after cardiac arrest using a single routine EEG and standardized interpretation according to the terminology proposed by the American Clinical Neurophysiology Society. Methods: In this cohort study, 4 EEG specialists, blinded to outcome, evaluated prospectively recorded EEGs in the Target Temperature Management trial (TTM t

Studier av olika material och deras egenskaper har en lång historia. Från de fyra elementen till alkemi och slutligen till modern fysik. Modern forskning ägnar mycket tid åt att undersöka exotiska material som beter sig på annorlunda sätt än metaller och endast existerar under extrema förhållanden. De exotiska materialens beteende kommer ifrån hur elektronerna, de minsta av atomernas byggstenar, pThe subject of this work is the simulation of photoemission spectra of simple metals. The simulation is performed using a model based on a dynamical exchange correlation potential. Angle-resolved photoemission spectra at the Γ point, and valence band photoemission spectra are simulated for Li, Na, K, Rb, Cs, Mg, Al and Si. The predicted bandwidths show good agreement with experimental results, wit
This thesis involves phenomenological models for describing high energy particle collisions. One class of these models, multiparton interactions (MPI), deals with the fact that when colliding two hadrons, it is possible for more than one pair of their constituents to interact. The other deals with parton showers, which are used to fill enhanced regions of phase space and give fully exclusive final
PURPOSE: Prostate-specific antigen (PSA) defined biochemical recurrence (BCR) of prostate cancer is widely used for reporting the outcome of radical prostatectomy (RP). A standardized BCR definition is lacking, and overall progression-free probability and risk of subsequent metastatic disease progression may vary greatly depending on the PSA criterion used. Ten definitions of BCR were evaluated to
The purpose of the study was to examine counselors experiences and challenges regarding the work with the child perspective within child and adolescent habilitation in relation to the obligation to report. The study was conducted through interviews with seven counselors from various habilitation clinics in Region Skåne. The results indicate that counselors have an advisory and supportive role towa
Vårdnadsreglerna, framför allt regleringen om gemensam vårdnad, har gjort en omfattande utvecklingsresa från 1970-talet och framåt. Uppsatsen syftar till att belysa, med en rättsdogmatisk metod, vilka förändringar som gjorts och vilket perspektiv som ligger bakom dem. Regleringen har gått från att gemensam vårdnad enbart var aktuellt för gifta föräldrar, till en presumtion om att gemensam vårdnad The Swedish custody regulations can be found in the Children and Parents Code. These rules have gone through a huge development during the modern times. This essay aims to illustrate which changes has been made and the perspectives behind them. The regulation has gone from joint custody for married parents only, to a presumption that joint custody always shall apply and on to that the custody shal
Patent law has been prevalent in climate change discussions, as a factor linking technology, Intellectual Property Rights (IPRs) and the climate crisis. The inventive step, its set threshold and the environmental benefits for the assessment of its current state, are one of the paths where patent law can act as a potential promoter of green technologies. This paper aims to asses how patent law can
The purpose of this essay is to closer study the narrative of Saint Lucy in Jacobus de Voragine’s work Legenda Aurea to be able to contribute to the present lack of research regarding Lucy of Syracuse. The essay uses the theories of cultural memory and the theoretical narratological framework of Mikhail Bakhtin to answer the question on how Lucy is portrayed in the Legenda Aurea. Furthermore, the
Små parker med vatteninslag och blandad struktur är bäst för Malmöbor Den rådande stadsplaneringstrenden är att förtäta städer. Detta har många fördelar, men städer med mycket hårdgjord yta är också känsligare för klimatförändringar. Genom att planera för gröna ytor på platser som inte är lämpade att bygga hus på kan man hjälpa till att klimatsäkra staden. Målet med detta arbete var att identifie
Special Purpose Acquisition Companies are surging in popularity as a way for companies to go public. As half of the initial public offerings on US stock exchanges were SPACs in 2021 there seems to be no indication of SPACs slowing down. This thesis examines the performance of companies that went public via a business combination with a SPAC in the year 2020 compared to companies that decided to ta
Purpose: The purpose of this study is to increase the understanding of how factors related to knowledge in itself, the environment, the sender, the receiver, and the sender and receiver affect knowledge transfer between departments in different business sectors. We also intend to clarify differences between sectors and to map these differences. Methodology: As we have aimed to clarify what factor
I Sverige lever många barn i hem präglade av våld och övergrepp, trots att de har en ovillkorlig rätt till skydd. Umgänge med en våldsutövande förälder, även kallat tvångsumgänge, kan få allvarliga konsekvenser för barnet. När domstolen beslutar om umgänge ska barnets bästa vara avgörande. Vid bedömningen av barnets bästa ska risken för att barnet far illa särskilt beaktas. Syftet med uppsatsen ä
