Trafficking is a growing problem in the whole world, also in Asia. Additionally, more attention has been drawn to the problem due to the ill treatment of many women, especially in the sex sector. Despite the huge amounts of people, mostly women and children, being trafficked every year and the attention drawn to the problem, there has not until recently been a universal definition of trafficking,

Bacteria: Building the Future from Thin Air Imagine what would happen if you could make nylon and other things that are needed to create everything from clothes to plastic containers with the use of microorganisms. It may seem far-fetched, but it’s getting closer to becoming reality. All you would need to get started is to help a few species of very special bacteria get even better at something t

With the aim to understand prolonged and repeated marine anoxia after the Triassic-Jurassic massextinction event, a continuously cored, 338 metre thick succession of Rhaetian to Toarcian sediments was retrieved close to the village of Schandelah near Braunschweig (Lower Saxony, northern Germany). Here, preliminary biostratigraphical, lithological, sedimentological, geochemical, and geophysical bor

För en utförlig populärvetenskaplig sammanfattning, vänligen följ länken till höger på denna sidan. De svenska utbildningsmyndigheterna står inför ett seglivat problem. Lärare har under många år uttryckt missnöje över alltmer utbredda och genomgripande krav på dokumentation. En hel del dokumentation stjäl tid som annars skulle kunna läggas på elevers lärande och att utveckla undervisningen, lyder The Swedish education authorities are up against a tenacious problem. Teachers have for years expressed dissatisfaction over increasingly prolific and pervasive demands for documentation that hijacks time that could have been invested in pupils’ learning. Over the past 15 years different Swedish governments have sought to remedy this problem but to no avail. The ‘burden of documentation’, as it is

By combining acoustic fields and liquid flows in microchannels we develop tools to chart and separatebiological particles based on their bio-mechanical properties. I will present an overview of three ongoingprojects where acoustic forces are utilized to separate blood cells.We studied the packing behavior of whole blood in a sound field. We discovered that cells self-organizesuch that red blood cells

Denna avhandling handlar om hur arkitektur producerar normer genom hållbar stadsutveckling, från formulering av visioner och strategier till materialisering och design. Den handlar också om arkitekturens potentiella roll i att omförhandla och utmana den normativt utstakade vägen framåt, till förmån för alternativa förhållningssätt. Hållbar stadsutveckling beskrivs i avhandlingen som en typologi avArchitecture, planning and urban design are some of the professional practices that contribute to the spatial aspects of societal organization and enable everyday life to run smoothly. The urgent and intertwined challenges of climate change and social injustice have introduced new dimensions to these tasks, frequently framed as working towards ‘sustainable development.’ In this doctoral thesis, I

Visualisering är ett viktigt verktyg för förståelsen av olika fenomen inom mekaniken. Vid datormodellering med finita elementmetoden utförs flera steg som med hjälp av visualisering kan underlätta förståelse och inlärning. CALFEM är ett finita elementverktyg utvecklat vid LTH, med fokus på utbildning. För att verifiera att en finita elementmodell är korrekt utformad är det viktigt att kunna visualVisualizing results is an important part of Finite Element (FE) modeling. Many tools exist for visualizing these results, they are often part of complete software packages for FE analysis. These packages often rely on the user being familiar with FE analysis, making them unsuitable for use in teaching the FE Method. CALFEM (Computer Aided Learning of the Finite Element Method) is an FE toolbox de

Det finns en stor potential för ett ökat utnyttjande av biomassa för energiändamål i Sverige. En ökad användning av biomassa skulle kunna bidra till att minska utsläppen av koldioxid från förbränning av fossila bränslen, minska beroendet av importerade fossila energibärare samt påverka den regionala och lokala miljösituationen såväl positivt som negativt. Föreliggande studie behandlar framför alltThere is a large potential for increasing the use of biomass for energy purposes in Sweden. Increasing the use of biomass can reduce emissions of carbon dioxide (CO2) from fossil-fuel combustion and dependence on imported fossil fuels. Furthermore, increased biomass use will affect emissions of other air pollutants than carbon dioxide as well as environmental impacts from land use. The study deals

Popular Abstract in Swedish Runt 1750 upptäckte en tysk kemist vid namn Marggraf att det var möjligt att utvinna socker från betor. Ett par decennier senare började en av hans studenter, Archard, att selektera betor utifrån deras sockerhalt och öppnade också världens första sockerbetsfabrik år 1801. Mängden utvunnet socker per rot låg runt 4 %. Sedan dess har förädling och förbättrade jordbruksmetAround 1750 a German chemist discovered it to be possible to extract sugar crystals from beet juice. Since then, breeding and improved agricultural practices have increased the concentration of sucrose per root from around 4% to around 18%. Sugar content is still one of the most important characters in sugar beet breeding, but breeders of today are also faced with many more characters, many of a c

Extensive research has demonstrated a tumor-promoting role of increased WNT5A expression in malignant melanoma. However, very little light has been shed upon how WNT5A expression is up-regulated in melanoma. A potential regulator of WNT5A expression is the pro-inflammatory cytokine Interleukin (IL)-6, which shares the ability of WNT5A to increase melanoma cell invasion. Here, we investigate whethe

This study investigates particulate matter (PM) and regulated emissions from renewable rapeseed oil methyl ester (RME) biodiesel in pure and blended forms and contrasts that to conventional diesel fuel. Environmental and health concerns are the major motivation for combustion engines research, especially finding sustainable alternatives to fossil fuels and reducing diesel PM emissions. Fatty acid

Visual cues provide an important means for aerial creatures to ascertain their self-motion through the environment. In many insects, including flies, moths, and bees, wide-field motion-sensitive neurons in the third optic ganglion are thought to underlie such motion encoding; however, these neurons can only respond robustly over limited speed ranges. The task is more complicated for some species o

Sprays are commonly found in, among other, combustion, agriculture and food processing. For each of these applications, the understanding of spray liquid dynamics is crucial for optimization of efficiency, accuracy, and robustness of the spray­-system in use. Sprays are also found as a collection of respiratory droplets ejected when people are speaking, yelling, coughing etc. that is one of the ma

Bridging the pressure gap between surface science studies and industrial processes requires a combination of well-studied reactions, model systems as catalysts, and advanced techniques capable of detecting structural changes under realistic pressure conditions. Observations from such studies provide helpful insight into the present phases of the gas-surface boundary and transitions that happen dur

This project is an investigation in atmosphere, and an attempt to create a new architectural idiom through the vernacular Japanese building style minka, the ambiance and context of the woods, and, importantly, by exploring whether it is possible to keep the crookedness from the first sketches throughout the whole process, into the completed building. Minka are traditional preindustrial homes for

Businesses today need to recognize that they have to be fast at realizing and exploiting new competitive advantages before the opportunity is lost. Instead of the traditional focus on price and quality, there is a shift towards the delivery of value to customers. This is strongly connected to the reduction of downtime of production and high reliability. Here the spare parts supply chain plays an i

During the Devonian, 377 Ma ago, the Earth was impacted by a large celestial body, striking ground in the Siljan area in Dalarna, Sweden. The impact created what is today the largest confirmed impact structure in western Europe. Since its formation, the structure has however been heavily eroded, leaving no trace of the original crater. Today, it is instead recognizable due to the central plateau a

The large-scale expansion of wind energy is an important element of the energy transition in Germany and a necessary tool to mitigate climate change. Yet, it is contested in many rural settings across the country. This thesis builds on the argument that rural areas are a crucial factor for the energy transition. They serve as the sites that host most of the infrastructure needed in the transition

The Swedish national library has collected nearly all Swedish printed materials for more than three centuries. Regarding digital material, the digital legal deposit act was enacted about nine years ago. According to the law, a selection of digital publications must be sent to the national library for preservation. The Swedish digital legal deposit act has been heavily criticized, mostly because it
