Populärvetenskaplig sammanfattning: Conodonter är stratigrafiskt användbara, fosfatiska mikrofossil, som påträffas i marina sediment mellan senkambrium till slutet av trias (520-210 Ma). Olika formtyper av conodonter, eller conodontelement, byggde tillsammans upp käkapparaten hos det lilla ål-liknande conodontdjuret, som numera räknas till chordaterna. Jag har undersökt förekomsten av conodontsläkSeven taxa of the conodont genus Ctenognathodus (Fay, 1959) sensu Viira, 1982b in the Silurian of Gotland have been described and their occurrence mapped geographically, stratigraphically and related to facies. In addition to C. murchisoni (Pander, 1856) three new species were found; C. n. sp. D, C n. sp. E and C n. sp. I with two subspecies, I and G. Two taxa formerly known as subspecies of Ligon

Premise: Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia. Methods: We measured floral traits, reflectance of petals and nectar-guide

Eco-roofs are becoming popular for aesthetic reasons and also as units of stormwater systems. It is thought that such roofs with soil cover and vegetation reduces the total runoff, the peak flows and improves the quality of the roof water. Here are reported investigations of runoff from thin, 3-4 cm soil, extensive green roofs with sedum-moss in southern Sweden. The two-year study was performed on

Background: Physical activity (PA) in childhood is critical for establishing a healthy lifestyle across the lifespan, particularly to treat and prevent obesity. This study aimed to explore PA and sedentary behaviour (SED) in 6–12-year-old children with obesity and their parents, and possible associations in these behaviours between children and parents. Methods: Children referred to outpatient pae

Background The dura mater has a permeable vasculature similar to that of peripheral organs, and is separated from the brain, which is enclosed within the arachnoid barrier. Fluid and solute transport across the arachnoid barrier between the subarachnoid space (SAS) and dura is crucial for brain waste clearance and immune surveillance, but few neuroimaging approaches can capture this dynamic proces

Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.The purpose of this thesis is to examine the physiological role of

Long-term stability of endosseous implants depends on successful bone formation, ingrowth and adaptation to the implant. Specifically, it will define the mechanical properties of the newly formed bone-implant interface. 3D imaging during mechanical loading tests (in situ loading) can improve the understanding of the local processes leading to bone damage and failure. In this study, titanium screws

The novel method of modification of polyethersulfone (PES) ultrafiltration membranes is proposed. This method involves the use of aqueous solutions of polyacrylic acid (PAA) of different molecular weights (Mn=5.1×103 g·mol–1, Mn=490×103 g·mol–1) as a coagulant in non-solvent induced phase inversion process (NIPS). Addition of PAA (0.05–1.5 wt%) to the coagulation bath leads to marked changes in pe

BACKGROUND One of the most challenging tasks of modern biology concerns the real-time tracking and quantification of mRNA expression in living cells. On this matter, a novel platform called SmartFlareTM has taken advantage of fluorophore-linked nanoconstructs for targeting RNA transcripts. Although fluorescence emission does not account for the spatial mRNA distribution, NanoFlare technology has g

Introduction: Monoaminergic activity modulates nociceptive transmission in the central nervous system (CNS). Although pain is the most disabling symptom of osteoarthritis (OA), limited knowledge exists regarding the CNS mechanisms that amplify pain and drive sensitization processes in humans.Objectives:The main objective of this study was to evaluate associations between cerebrospinal fluid (CSF)

The Central Valley of Cochabamba is located in the Andes mountain range, Bolivia. This region experiences several water related challenges such as a scarcity of surface water, an increasing water demand, a growing urbanization in groundwater recharge areas, and a declining water table due to intensive groundwater extraction. The valley has been influenced by both alluvial and fluvial depositions t

Sammanfattning Bakgrund: Stroke är en av de vanligaste folksjukdomarna i Sverige där 27 000 - 35 000 personer drabbas varje år. Stroke är ett samlingsnamn på vaskulära skador i hjärnan, vilka kan vara ischemiska eller till följd av blödning. En vanlig nedsättning hos personer drabbade av stroke är balansproblematik. Balansen är väsentlig för en självständig vardag och påverkar även den drabbades

The positive correlation between elevated expression of wingless-type mammary tumor virus integration site family member 5A (WNT5A) and metastatic potential in melanoma has been extensively explored. However, detailed mechanistic aspects regarding how WNT5A promotes increased melanoma aggressiveness remains unknown. Myristoylated alanine-rich C-kinase substrate (MARCKS), an intracellular protein c

This thesis is a concept study performed at Caran AB by order of Volvo Car Corporation, VCC. The background is a market research performed by VCC. From the research, a need for a product that facilitates reaching the trunk level in Volvo’s SUV, XC90, was recognized. It was also found, that dogs seem to find it difficult to get up in the trunk, why dogs have been accounted for during the developmen

2010 års straffrätts reform initierades som en reaktion på att straffen för de grövsta formerna av misshandel endast dömdes ut i den nedre fjärdedelen av straffskalan. Reformen medförde bl.a. att straffskalan för grov misshandel i 3 kap. 6 § delades upp i två stycken, där andra stycket med en strängare straffskala på fyra till tio år skulle vara tillämplig för synnerligen grova fall. De grövsta faThe criminal reform of 2010 was initiated as a reaction to sentencing levels being concentrated to the lower quarter of the range of punishment for serious cases of assaults. The reform led to the division of the range of punishment for aggravated assault in chapter 3 article 6, to two separate subsections. The second subsection would apply a range of punishment between four to ten years applicabl

Aktivt kol har identifierats som en av de mer effektiva metoderna när det kommer till att avlägsna organiska mikroföroreningar (OMF) från avloppsvatten. Aktivt kol är ett poröst material med stor ytarea som kan adsorbera andra ämnen. Det är inget som existerar naturligt utan behöver framställas. Framställningen kan ske från i princip vilket material som helst som har en hög kolhalt. En stor del avActivated carbon has been identified as one of the more effective methods of removing organic micropollutants (OMP) from wastewater. Activated carbon is a porous material with a large surface area that allows adsorption of other substances. The material does not exist naturally and therefore has to be produced. The production can be done from any carbon-rich material and today the precursor is mai

Molnens roll i klimatsystemet har studerats och deras påverkan på solens inverkan på jordens energibalans. Jordens albedo påverkar energibalansen genom att den påverkar hur mycket av solens instrålning som reflekteras eller absorberas. Moln påverkar jordens albedo och spelar därför en viktig roll i denna balans. Molnbildning sker till nära 100% i troposfären och där finns allt det vi kallar väder.The role of clouds in the climate system has been studied and their impact on the Sun's impact on the Earth's energy balance. The Earth's albedo affects the energy balance by influencing how much of the Sun’s radiation is reflected or absorbed. Clouds affect the Earth's albedo and therefore play an important role in this balance. Cloud formation occurs almost 100% in the tropospher

Among the main objectives there is the estimation of the water b

Mellan cirka 30-50 procent av den mat som produceras i världen årligen kommer aldrig människan tillgodo som föda. Att mat slängs eller på annat sätt går förlorad i livsmedelskedjan är ett stort problem, framför allt för att många människor i världen inte har tillgång till mat men också för att produktionen av livsmedel medför en betydande miljöpåverkan. Vad gäller statistiken över matsvinnet är deIt is estimated that between 30 and 50 percent of the food produced in the world annually will never be consumed by humans. The fact that significant amounts of food are lost or thrown away in the food supply chain is not just an environmental issue; above all it is a huge problem because many people in the world do not have access to food. Lost food and waste appears throughout the whole food sup

Framväxten av digitala plattformar håller för närvarande på att förändra hur kulturarbete förmedlas och utförs. Trots detta finns det en brist på forskning, inte minst i en svensk kontext, som studerar kulturarbete som ett typexempel på det som kommit att kallas gigarbete. Den här avhandlingen analyserar frilansande kulturarbetares erfarenheter av att navigera den digitala plattformsekonomin för aCultural industries are currently being transformed by processes of platformization and precarization. Despite being among the sectors where platformization has already had the most pronounced effects, there remains a lack of research on cultural work as a prototypical example of so-called gig work.
