Naturlig selektion i vilda skalbaggspopulationer Naturlig selektion är en nyckelfaktor för evolutionen. Även om vi vet att mängden variation i egenskaper (fenotyper) ger råmaterial för selektion och om den är genetisk påverkar evolutionens hastighet, har vi fortfarande mycket att lära om hur naturlig selektion påverkar specifika egenskaper över tid. I min examensuppsats undersökte jag hur naturliNatural selection is an important force behind evolution. It is well known that phenotypic variation provides opportunity for evolution, but research into how selection acts on specific traits over time is lacking. In this thesis, I studied how selection acts upon the shape and body size of the beetle Cassida viridis. Across three populations, I measured size (length and area), shape, and lifespan

Aims. In this work, we aim to make a differential comparison of the neutron-capture and p-process element molybdenum (Mo) in the stellar populations in the local disk(s) and the bulge, focusing on minimising possible systematic effects in the analysis. Methods. The stellar sample consists of 45 bulge and 291 local disk K-giants observed with high-resolution optical spectra. The abundances are dete

This invention comprises, on one hand, a method of detecting and quantifying components separated by capillary electrophoresis or other technique using thin capillaries in the separation, and on the other hand, an apparatus for performing this detection. The method comprises irradiating the whole or large parts of the capillary at short time intervals and detecting the fluorescence originating fro

On the face of it, Hume’s understanding of the relationship between virtue and moral sense seems clear enough. According to Hume, a virtue is a quality of mind or character trait that produces approval, and vice a quality of mind that produces blame ( T 614; cp. 473,575). This relationship between virtue and vice and our moral sentiments is described and analysed by Hume as part of his wider and m

The present invention relates to a method of isolating a desired nucleic acid from a biological solution, which method comprises to selectively precipitate the desired nucleic acid by adding a polycationic precipitating agent to the solution and allowing it to form a complex with said nucleic acid, wherein the precipitating agent is a highly charged linear polymer that comprises quaternary amino g

The invention concerns a method for determining the concentration of a constituent in an assay system within a capillary tube from which light is emitted, the light being proportional to the amount of the constituent to be assayed. The light from the system is detected and quantified, and the detection takes place from substantially the longitudinal direction of the capillary tube.

The rise of water-based electromagnetic devices opens up new possibilities for controlling electromagnetic performance due to the liquid state of crucial parts of the device. This letter proposes the siphon mechanism as a novel way to achieve reconfigurability in these types of electromagnetic devices. To demonstrate this, a simple polarization-reconfigurable device based on a siphon is introduced

We are interested in rationalizing the phenomenon of like-charge attraction between charged bodies, such as a pair of colloids, in the strong coupling regime. The two colloids are modelled as uniformly charged parallel plates, neutralized by mobile counterions. In an earlier work [Palaia et al., J. Phys. Chem. B 126, 3143 (2022)1520-610610.1021/acs.jpcb.2c00028], we developed an effective-field th

Involving a controlled reduction of body temperature (lowering of 3 - 10 °C), nocturnal hypothermia is a common strategy among birds to manage the high energy expenditure required for body temperature regulation, particularly during periods of elevated metabolic demands. In this study, I investigated whether migrating passerines generally use controlled nocturnal hypothermia as a migratory strateg

This paper focuses on the development of a machine design environment for numeric modelling and analysis of radial flux machines. The design environment is based on Matlab/(Octave) environment, which calls numeric field analysis by FEMM/(Opera-2D). The analysis tool is intended for educational purposes; however it has proved to be a powerful research tool especially at early design stages.

In this manuscript, we illustrate how to use the newly proposed τ re-clustering algorithm to select jets with different degrees of quenching without biasing their initial transverse momentum spectrum. Our study is based on Z+jet simulated events using the JEWEL Monte Carlo event generator to account for jet quenching effects. We apply the τ re-clustering algorithm to extract a proxy for a time axi

We present performance studies of the Time-of-Flight (ToF) subdetector of the ATLAS Forward Proton (AFP) detector at the LHC. Efficiencies and resolutions are measured using high-statistics data samples collected at low and moderate pile-up in 2017, the first year when the detectors were installed on both sides of the interaction region. While low efficiencies are observed, of the order of a few p

A deep understanding of double-directional wireless channels is imperative for wireless system design. This necessitates the development of precise channel models through channel sounding. Given the dynamic nature of wireless channels, a short measurement time is highly desirable. In this paper, we present and validate a dual-polarized millimeter-wave channel sounder that uses a rotating mirror me

The minimization of the total variation is a well-established technique of preservingedges and discontinuities. Therefore it has wide applicability in image processing,where one is interested in recovering a corrupted image while preserving edges inthe image. In the last decades, in the literature, there have been introduced manydifferent approaches and algorithms for minimizing the total variatio

Soloexhibition in Berlin.A conditional sentence is formed by a main clause (the consequence), a conjunction (if), and a conditional clause (the condition). There are four standard types of conditionals. Cesarco’s exhibition proceeds from the given to the not given, comparing what is with what could be or might have been. In some ways, this is equivalent to what happens in the studio, or what happe

Chosen Memories brings together contemporary works by Latin American artists who have been investigating history as source material for their work.

Collaboration across disciplines and stakeholders is important in handling complex societal problems. Even if collaborating is acknowledged as contributing towards societal change and innovation, collaborators’ emotional experiences during development, consolidation and completion of a given project are underexplored. This article discusses emotional labour in three cross-sectoral collaborations u

Importance: Repeat expansion of CGG in LRP12 has been identified as the causative variation of oculopharyngodistal myopathy (OPDM). However, to our knowledge, the clinicopathologic features of OPDM with CGG repeat expansion in LRP12 (hereafter referred to as OPDM_LRP12) remain unknown. Objective: To identify and characterize the clinicopathologic features of patients with OPDM_LRP12. Design, Setti

The role of magnetic fields for the formation of planets is reviewed. Protoplanetary disc turbulence driven by the magnetorotational instability has a huge influence on the early stages of planet formation. Small dust grains are transported both vertically and radially in the disc by turbulent diffusion, counteracting sedimentation to the mid-plane and transporting crystalline material from the ho
