Our understanding on how organisms evolutionarily cope with simultaneously occurring, multiple threats over generations is still elusive. In a long-term experimental study, we therefore exposed clones of a freshwater cladoceran, Daphnia magna, to threats from predation and ultraviolet radiation (UVR) during three consecutive parthenogenetic generations. We show that Daphnia can adapt to different
Birds have been observed to have dietary preferences for unsaturated fatty acids during migration. Polyunsaturated fatty acids (PUFAs) may increase the exercise performance of migrant birds; however, PUFAs are also peroxidation prone and might therefore incur increased costs in terms of enhanced oxidative damage in migratory individuals. To shed light on this potential constraint, we analyzed plas
Adiabatic laminar burning velocities and post-flame NO concentrations for flat, non-stretched, premixed C2 H 4 /air flames were experimentally determined with a heat flux burner of improved design, over equivalence ratios ranging from 0.7 to 2, at atmospheric pressure and initial temperature of 298 K. Recognizing that C2 H 4 is a main intermediate in high-temperature oxidation pathways of heavy hy
We report accurate in-situ optical measurements of surface temperature, volatile gas temperature, and polycyclic aromatic hydrocarbon (PAH) emission over the whole burning history of individual biomass pellets in various combustion atmospheres. Two biomass fuels, wood and straw, were prepared in cylindrical pellets of ~300 mg. The pellets were burned in a well-controlled combustion atmosphere prov
Aim: To describe the experiences of peer learning in psychiatric inpatient settings during clinical placement of undergraduate nursing students and to highlight the possibility for peer learning in psychiatric outpatient settings. Design: A qualitative inductive design. Method: Questionnaires with 14 students and 12 preceptors in inpatient and outpatient care and interviews with one student and on
Social learning, especially triple-loop social learning involving institutional and governance changes, has great potential to address urban water issues such as flooding, drought, and pollution. It facilitates urban transition and the adoption of more systemic approaches and innovations. Social learning in water governance is a growing field, but the triple-loop learning concept remains vague and
Gerard Quinn advances the proposition that there is a ‘legal culture’, which consists of unstated values and institutional expectations that underpin legal orders and constitute a ‘morality’ which enables law to be possible. He focuses on the United Nations Convention on the Rights of Persons with Disabilities (CRPD 2006), in particular on Article 12-Equal recognition before the law, to discuss th
The integration of 3D city models with Building Information Models (BIM), coined as GeoBIM, facilitates improved data support to several applications, e.g., 3D map updates, building permits issuing, detailed city analysis, infrastructure design, context-based building design, to name a few. To solve the integration, several issues need to be tackled and solved, i.e., harmonization of features, int
In this paper, the interaction between different organic and inorganic K/S/Cl compounds in the solid structure of biomass is studied and a model is presented to predict the temporal release of Kg, HCl, CH 3 Cl, KCl, KOH, K2 SO4 and SO2 from biomass devolatilization. Four types of pulverized biomass are chosen from literature, two of which have no chlorine content and two with chlorine content in l
Objectives: This study aims to test the feasibility of the Fracture and Mortality Risk Evaluation (FAME) Index. Patients and methods: Two academic centers in Lithuania and Turkey participated in this retrospective study conducted between November 2018 and July 2019. A total of 100 consecutive patients (22 males, 78 females; mean age 78.9 years; range, 45 to 100 years) with low energy proximal femu
En antologi med artiklar om dels filmhistoria, dels film och historia.
Artikel om relationen mellan film och historia med betoning på den forskning som Erik Hedling, professor i filmvetenskap vid Lunds universitet, har bedrivit.
Artikel om slaget vid Alamo 1836, hur det har hanterats i amerikansk och mexikansk historieskrivning, hur platsen har förändrats från slagfält till museum och analyser av filmer och tv-serier om bataljen.
Diffusion tensor distribution (DTD) imaging builds on principles from diffusion, solid-state and low-field NMR spectroscopies, to quantify the contents of heterogeneous voxels as nonparametric distributions, with tensor “size”, “shape” and orientation having direct relations to corresponding microstructural properties of biological tissues. The approach requires the acquisition of multiple images
Purpose: To develop a treatment model of rhegmatogenous retinal detachment (RRD) in which the effects of various vitreous tamponades can be explored. Methods: In a primary session, detachment was produced in the right eye of 24 rabbits using vitrectomy, posterior vitreous detachment, retinal break induction, and subretinal injection of viscoelastic solution. The following day, detachments were tre
There is a growing body of literature concerning the social construction of crisis. This study aimed to clarify inconsistencies regarding the social constructionist perspective by examining how the key terms of social constructionism are applied in crisis communication and crisis management studies. Through an analysis of 65 scholarly works in both communication and business journals, this study p
It is unclear whether 12-lead ECG employing standard criteria for left ventricular hypertrophy (LVH) provides similar information with respect to long-term cardiovascular risk as echocardiography. The authors performed a retrospective cohort study of 1376 individuals without cardiovascular disease, who underwent ECG (LVH defined using the Sokolow-Lyon voltage combination (>35 mm) or the Cornell vo
In a recent study, Bai (2013) proposes a new factor analytical (FA) method for estimation of stationary dynamic panel data models with fixed effects. Our interest in this method originates with the fact it does not require explicit demeaning of the data, a practice that is known to cause problems of bias and low power in near unit root panels. The purpose is to study the properties of FA when appl
BACKGROUND: Previous research has shown that Common Mental Disorders (CMD) are unequally distributed between population subgroups, but we know less about how labour outcomes following such disorders are distributed. Our aim is to investigate how the labour outcomes following a CMD diagnosis differ over sex, age, schooling and country of birth.METHODS: We use a population sample from southern Swede
Woody pastures represent keystone habitats for biodiversity in agricultural landscapes, contributing to increased resource availability, landscape heterogeneity and structural variability. High taxonomic diversity is closely linked to vegetation structure in woody pastures, but examining functional characteristics of species assemblages can shed more light on the ecological mechanisms driving dive
