Black carbon is an ever-growing global problem and one of the most important environmental issues of this generation. Black carbon, also known as soot, is a highly polluting substance and it is the second-largest polluter after carbon dioxide. BC consists of pure carbon in various forms and is produced by the incomplete combustion of fossil fuels, biofuels, and biomass. It is transported by air mo
Programmable shading provides artistic control over materials and geometry, but the black box nature of shaders makes some rendering optimizations difficult to apply. In many cases, it is desirable to compute bounds of shaders in order to speed up rendering. A bounding shader can be automatically derived from the original shader by a compiler using interval analysis, but creating optimized interva
The International Union of Geological Sciences (IUGS) announced the list of The Second 100 IUGS Geological Heritage Sites at the 37th International Geological Congress (IGC) in Busan, Republic of Korea.

Particulate methane monooxygenase (pMMO) is one of the few enzymes that can activate methane. The metal content of this enzyme has been highly controversial, with suggestions of a dinuclear Fe site or mono-, di-, or trinuclear Cu sites. Crystal structures have shown a mono- or dinuclear Cu site, but the resolution was low and the geometry of the dinuclear site unusual. We have employed quantum ref
Mobiloperatörer har under en längre tid haft en stark fokusering på konsumentmarknaden och i flera avseenden försummat företagsmarknaden för mobila tjänster. Detta har till viss del förändrats under de senaste åren i takt med utvecklingen av mobil e-post som primärt riktas mot företag och organisationer. Vi har uppmärksammat denna förändring och därmed intresserat oss för organisationers användnin
An exhibition of the fossil era It is 2053. The Swedish government has just opened its landmark museum FOSSIL with its first exhibition Carbon Ruins. The exhibition and its grand opening is a celebration of the fact that global net-zero emissions of carbon dioxide were reached in 2050. Sweden, in line with its 2017 targets, reached net-zero emissions of greenhouse gases already in 2045, being the

Black Carbon Black Carbon – Formation, life cycle, impacts, co-benefits, policy, mitigation and response measures The Soot theme at the Pufendorf Institute This initiative develops a multi- and cross-disciplinary research program centered on soot from domestic and industrial combustion processes. Also called black carbon or elemental carbon, soot is a major driver of climate change and contributor

Popular Abstract in Swedish Ett stort antal fåglar flyttar vår och höst mellan sina häckningsplatser hos oss i norr till “övervintringsområden”. Många flyttar över stora avstånd, till södra Europa eller till Afrika. Ofta är flyttfåglarnas mål väl definierat, det händer att en fågel häckar på exakt samma plats år efter år. Det finns observationer från t.ex. Afrika att fåglar kan vara lika trogna siBirds are generally capable of accurate orientation. In this thesis I present studies about the external cues and the ecological factors that influences bird orientation. A multitude of environmental cues are used to select and maintain a proper direction. These are visual cues, like the sun and the starry night sky, but other cues like the geomagnetic field, wind and odours also play important ro
This paper valuates two different financial contracts, the European Call and the Spread option using the Fourier transform. In the European Call case the underlying asset is modelled by the geometric Brownian motion stochastic differential equation. All necessary conditions in order for the transform to exists are examined and it turns out that the payoff needs to be scaled by an exponential facto
The soot emissions from diesel engines are much higher in transient operation than during steady state operation. In this thesis, a method for estimating the soot mass flow emission in transient drive cycles is presented. The proposed method uses stationary emission maps in combination with step responses. Bandpass filters are used to filter the engine torque/power to provide transient detection a
We present new coarse resolution (0.5° × 0.5°) vegetation height and vegetation-cover fraction data sets between 60° S and 60° N for use in climate models and ecological models. The data sets are derived from 2003–2009 measurements collected by the Geoscience Laser Altimeter System (GLAS) on the Ice, Cloud and land Elevation Satellite (ICESat), the only LiDAR instrument that provides close to glob
Below some helpful tips to consider when working in a digital environment. If you have headsets / headphones - feel free to use them as you hear and are heard better. Regardless if you´re using headphones or mobile / computer: Test the sound related to what you hear (the speaker) and what you say (the microphone). If possible, do it well in advance of a meeting. When connecting to a meeting, ha

En människa exponeras och angrips varje dag av virus och bakterier och immunförsvaret skyddar oss från dessa angrepp. Immunförsvaret utgörs av vita blodkroppar som bildas i benmärgen och sprids vidare ut i kroppen. De vita blodkropparna finns i många olika varianter och varje variant har en specifik uppgift. Lymfocyter är en typ av vita blodkroppar och kan dela in i två huvudgrupper: Blymfocyter oToday antibodies are an important part in the treatment of diseases such as cancer and Guillain–Barré syndrome. It is of course important to be able to regulate the levels of the antibodies in the treatment. In this study a general method for antibody production were investigated. The antibody construct was made for transportation out of the cell. Four different tagged variants of an antibody wer

Bees, ants, and wasps are well known to visually navigate when traveling between their nests and foraging sites. When leaving their nest, landmarks in the vicinity are memorized and used upon return to locate the nest entrance.1,2 The Neotropical nocturnal sweat bee Megalopta genalis navigates under the forest canopy at light intensities ten times dimmer than starlight.3 Despite these dim conditio
