The tribe Ithomiini (Nymphalidae: Danainae) includes nearly 400 species of butterflies distributed from Mex-ico to Northern Argentina, and adults of all species are aposematic and the main models in several Neotropical mimicry rings. The subtribe Melinaeina, a small group composed of five genera of large ithomiines, is the sister group of all remaining groups in the tribe Ithomiini. With 14 recogn

PurposeLeucine rich alpha-2 glycoprotein 1 (LRG1) has emerged as a promising biomarker for appendicitis, especially in pediatric patients. However, the currently available data are sparse, and the biomarker must be validated in more settings and compared to standard inflammatory markers. We aimed to evaluate the diagnostic and discriminative utility of serum and urine LRG1 in children with other c

The articles included in this thesis centre on what can be called the normative basis of risk analysis. Since risk analyses are decision procedures, they should adhere to norms of rational decision-making, and this they do. Most risk analysis schemes are built on a notion of the decision theoretic maxim that the goal of every decision is to maximize expected utility. However, for some thirty years

Varg har naturligt förekommit i hela landet genom historien men arten försvann nästan helt ur den svenska faunan under 1900-talet. Nu har vargen återigen etablerat sig i Sverige. Förutsättningarna för att förvalta varg genom jakt, så kallad licensjakt, är strikt begränsat. De bestämmelser som reglerar möjligheten till licensjakt på varg grundar sig på EU:s art- och habitatdirektiv, AHD. Dessa haWolves have occurred naturally across the country throughout history but disappeared almost completely from the Swedish fauna during the 20th century. Now the wolf has again established itself in Sweden. The prerequisites for managing wolves through hunting, known as licensed hunting, are strictly restricted. The provisions regulating the possibility to licensed hunting of wolves are based on the

The Arctic tundra has been considered as one of the most sensitive areas to global climate change. One impact of global warming is that permafrost thawing could result in more waterlogged and anaerobic conditions, and consequently an increasing release of methane (CH4) to the atmosphere. These potential CH4 emissions can further amplify global warming. Therefore, it is important to assess the quan

Åderförkalkning - En undersökning av plackstabilitet Åderförkalkning, eller ateroskleros, är en kärlsjukdom som orsakar förträngningar i kroppens artärer. Hjärt- och kärlsjukdomar är de vanligaste orsakerna till dödsfall globalt - det uppskattas att 17,5 miljoner människor gick bort till följd av dem 2012, vilket motsvarar 31 % av alla dödsfall det året. Det saknas därmed inte anledningar till atAtherosclerosis is a chronic disease of arteries. Cardiovascular diseases, of which atherosclerosis is an underlying mechanism, are the most common causes of death globally. The disease is characterised by lipids having penetrated the intima of the artery wall, accompanied by inflammation, fibrosis and endothelial hyperplasia. Accumulated cells, lipids, connective-tissue elements and debris from t

Abstrakt Bakgrund: Kvinnlig könsstympning definieras som delvis eller totalt avlägsnande av kvinnans könsdelar eller åsamkande av annan skada av icke-medicinska skäl. 2014 beräknades enligt WHO mer än 125 miljoner flickor och kvinnor vara könsstympade. I Sverige uppskattas det leva cirka 38 000 könsstympade kvinnor. Ingreppet kan medföra kronisk smärta, svårigheter i samband med miktion och meAbstract Background: Female genital mutilation (FGM) comprises all procedures that involve partial or total removal of the external female genitalia, or other injury to the female genital organs for non-medical reasons. According to WHO, 2014 more than 125 million women and girls were estimated to be cut. In Sweden, around 38 000 women are thought to have been victims of the procedure. Female g

Purpose: To explore whether the view on Business Models and Value Creation, can explain the lack of Venture Capital investments in green start-ups, by examining how green start-up Entrepreneurs, and Venture Capitalist investors, view these two factors. Theoretical framework: The aim of this thesis is to address some of the key knowledge gaps in research available today, regarding why there is a l

The question of secondary liability of internet intermediaries for illegal content online is closely linked to the enjoyment of freedom of expression that has to be guaranteed both online and offline. The provisions concerning internet service providers’ liability in Europe include ‘notice and take down’ procedure, blocking measures and injunctions against intermediaries, which are all well-desi

In developing countries across the world people are depending on rivers as a source of water for drinking, cooking and bathing. This is also the case in the Indonesian part of the island Borneo where this study was made. The largest river is the river Kapuas which, together with its tributaries, supplies the area with water. The hydrology of these rivers is changing and the quality of the water in

Abstract Today large amounts of macadam are being delivered for the production of asphalt. One of the requirements of the material that´s being used is the adhesion. The adhesion is essential for the performance of the coating. It minimizes the risk of stone chips and makes the construction of the pavement stronger etc. Several studies have been made using the Roller bottle method. The results sho

Freezing injuries usually take place in thawed plant-based food products. To reduce freezing injuries, Pulse Electric Field (PEF) treatment and Vacuum Impregnation (VI) of cryoprotectant were used before the freezing process. The aim of PEF is to provoke electroporation to the membranes of the plant cells, thereby allowing the cryoprotective solution impregnated by VI to penetrate the cells. PEF

Production of Red Blood Cells from Skin Cells Red Blood Cells (RBCs) are most important when it comes to delivering oxygen to different tissues and organs. This is why their production has to be continuously maintained. It is estimated that in humans over two million RBCs are produced every second to replenish the pool. On average their life span is around 120 days before they die and get replace

I takt med att coronapandemin blev mer påtaglig tvingades vårt samhälle till drastiska förändringar. När vi blev uppmanade att isolera oss ställde vi större krav på bostaden. Den skulle vara mer än bara ett ställe att bo på. Aktiviteter som vi tidigare utförde på andra platser, såsom arbete och träning, flyttade in i bostaden, och därmed blev hemmet en plats där vi spenderade både arbete och fritiAs the corona pandemic became increasingly manifest, our society was forced to make drastic changes. When we were told to quarantine, our place of residence had to provide for all the needs that could no longer be taken care of elsewhere, such as our work and workout routines. We looked to our home to fulfill these needs and thus our home became a place for both work and leisure. Our vision of wha

Den digitala utvecklingen under 2010-talet har medfört en möjlighet för personer att dela varor och tjänster bortom den närmaste bekantskapskretsen. ”Delningsekonomi” är hur denna nya företeelse har kommit att benämnas. En rad plattformsföretag, varav Uber är en av de främsta, har introducerat nya affärsmodeller där tjänster erbjuds via digitala plattformar och utförs av privatpersoner. Frågan om Digital development during the 2010s has enabled private individuals to share goods and services beyond their immediate acquaintances. This new economic model has been dubbed as “the sharing economy”. Several platform businesses, of which Uber is leading, have introduced new business models where services are offered via digital platforms but performed by private individuals. The question of how t

Staters rätt till självförsvar är ett undantag till det generella våldsförbudet och utgör ett såväl centralt som flitigt omskrivet område inom folkrätten. Regleringen för rätten kan påstås vara relativt enkel att återge så som den uttrycks i art. 51 av FN-stadgan och i ljuset av den internationella sedvanerätten. Rätten till självförsvar är däremot desto svårare att tillämpa i praktiken och en staThe right of states to self-defense is an exception to the general prohibition of the use of force and constitutes a central as well as a frequently debated subject in international law. The regulation of the right can be said to be relatively simple to pronounce as expressed in Art. 51 of the UN Charter and in the light of international customary law. The right of states to self-defense is howeve

När trapetskorrugerad plåt installeras som tak, skruvas den fast på överflänsen på den fackverksbalk som utgör takets bärverk. Takplåten har hög styvhet i planet, men dess styvhet minskar när deformation uppstår i taket, på grund av andra ordningens effekter. För att avgöra hur stor påverkan som detta har på en strukturs stabilitet, modelleras en byggnad i ett kraftfullt datorprogram där linjära oCorrugated galvanized iron (CGI), or corrugated sheet metal, is a lightweight roofing material that was invented in the early 1800s. The corrugation gives the steel an increased flexural strength in its installed direction and thus increases the amount of load the CGI-plate is able to carry and the span it can be effective at. Thanks to its light weight, corrugated sheet is one of the most commonl

År 2020 anger 212 av 286 kommuner i Sverige att de har ett underskott på bostäder i kommunen som helhet. Sveriges befolkning ökar och bostadsbeståndet hänger inte med. I studien syftar bostadsbristen till definitionen som är skillnaden mellan vad som kollektivt uppfattas som en godtagbar bostadssituation och det faktiska läget på marknaden. Situationer som inte kollektivt anses vara godtagbara bosThe housing responsibility in Sweden is primarily controlled by the municipalities. The municipalities in Sweden have a monopoly on controlling land use with detailed development plans. The population rises every day and the majority of the Swedish municipalities confirms having lack of housing. This study has been made in order to investigate how five municipalities work with their housing respon

Respiratory tract infections (RTIs) are a major global health concern. Several studies indicate that most respiratory bacterial pathogens are capable of asymptomatic colonization and find their primary ecological niche within the nasopharynx of healthy individuals as harmless commensals that form biofilms. However, in response to external factors, such as concomitant virus infections, colonizing b
