X-ray crystallography is the main source of atomistic information on the structure of proteins. Normal crystal structures are obtained as a compromise between the X-ray scattering data and a set of empirical restraints that ensure chemically reasonable bond lengths and angles. However, such restraints are not always available or accurate for nonstandard parts of the structure, for example substrat

INTRODUCTION: A reliable electrocardiographic predictor of ventricular fibrillation (VF) in patients with ST elevation myocardial infarction (STEMI) is lacking so far. Previous experimental/simulation study suggested a terminal T-wave inversion (TTWI) in ischemia-related ECG leads corresponding to anterior infarct localization as an independent predictor of reperfusion VF (rVF). This T-wave charac

Mykorrhiza motverkar läckage av kväve Tillgången på kväve (N) begränsar tillväxt i nästan alla land-ekosystem. Därför förväntas ekosystem optimeras för att hushålla med denna resurs. Förbränning av fossila bränslen och industriell tillverkning har nyligen fördubblat tillgången på N. Jag har undersökt hur träd ingår partnerskap med svampar för att effektivisera sitt upptag av N, och hur deras relaEctomycorrhizal fungi (EMF) mediate nutrient exchange between trees and soil in coniferous forests. Nitrogen (N) currently limits net primary productivity (NPP) in many terrestrial ecosystems but N deposition may alleviate this limitation, inducing limitation of phosphorous (P) instead. Studies have shown reductions in production of EMF mycelia (EMM) when trees are alleviated limitation of N, unle

"Transportation" is believed to be one of the main essential elements for the development of human civilization. From road to rail and from sea to sky. Till now, we human have formed many varied modes of transport that we facilitate in our daily lives. It is inevitable that a place that gathered the more people, the greater consumption of transportation. Many demanding cities like Londo

Agile Management is a management method based on the principles behind Agile Software Development. Compared to Traditional Management, Agile Management is more iterative and is therefore suited for fast paced and unsecure environ-­‐ ments. Even though agile is a fairly old methodology; there are few case studies outside the software industry. There are indi-­‐ cations, though, that Agile Managemen

The purpose with this thesis is to give the reader a holistic view of the 3D-print technology and how it can come to use in the construction industry. The purpose is also to spread knowledge about the technology. During the evaluation of the technology examines four aspects that an innovation needs to establish on the market, the aspects are: geographical resources, economical, law and social impa

Bovine milk contains several enzymes which can affect the quality of milk. One of these enzymes are lipases which hydrolyse the triacylglycerides in milk. In this process off-flavours, odour and product defects are generated. By controlling the enzymes activity, milk quality can be increased and therefore milk and dairy products can be stored for a longer time. This is desirable since the world de

In the fall of 2007 a collective of artists in southern Sweden made waves for themselves by attempting to construct a rather unique ‘club-format’ unlike any other in the [then] current Swedish underground club scene. Guided mainly by a self-proclaimed ‘notion of confusion’ as its foundational principle, the collective behind Klubb Kristallen branded itself as an aspiring anti-club by seeking to ch

When an agitator is in commission for an extended period of time the impellers can become clogged. In order to clean the impeller, the agitator is runned backwards. This is one of the main functions for a product that CG Drives & Automation is developing for a customer in the agitator business. The purpose of this bachelor thesis is to develop and test this product for CG Drives & Automati

I september 2017 fick nazistiska Nordiska Motståndsrörelsen demonstrationstillstånd i Göteborg, vilket orsakade en stor debatt i Sverige. En liknande debatt väcktes i USA 1977 när en nazistisk grupp ansökte om att demonstrera. Händelserna väcker frågor; bör demonstrationsfriheten innefatta nazistiska demonstrationer? Vad är statens förhållningssätt till våldsamma motdemonstranter? Syftet med uppsaIn September 2017, the Nordic Resistance Movement received a permit to march through Gothenburg, which ignited a big debate in Sweden. A similar debate was had in 1977 in the United States (U.S.), when a neo-Nazi group applied for a permit to demonstrate. These events provoke questions; should the right to demonstrate include neo-Nazi groups? What should the state’s approach be to violent counter-

The failure or flourishing of companies in their core businesses can often be attributed to events and developments rooting outside their focus of attention. Many research streams are concerned with early detection, interpretation and acting upon these weak signals from companies’ peripheries - with Peripheral Vision by Schoemaker & Day (2006) being one of the most systematic approaches. Due t

Today’s modern societies are becoming increasingly dependent on the vital societal functions that technical critical infrastructures provide, for example availability of electricity, tap water and internet connectivity. Hence, it is of essence that these infrastructures are resilient to interruptions. The purpose of this thesis is to investigate and contrast resilience levels of different types of

Vilka konsekvenser uppstår till följd av översvämningar och var riskerar de att bli som störst? Det är två frågor som vi bör ställa oss i arbetet med att minimera de negativa effekterna på samhället. De senaste åren har nyheterna om extremväder runt om i världen avlöst varandra. I samband med det förändrade klimatet förväntas både fler skyfall och perioder av torka att bli vanligare. Under sommarThe extreme short-term precipitation in Sweden is expected to increase due to climate change. This means that there will be an increased risk of floodings in urban areas. Several cloudbursts during the past decade have caused major damage to communities all over Sweden with high restoration costs as a result. To prevent further damage, solutions for managing increased amounts of water are needed.

Det är en varm och solig dag. Du ligger på rygg på en grönskande äng och ur ögonvrån ser du ett bi surra av och an tätt ovanför marken, på jakt efter nektar och pollen. Biet tar ett varv runt ängen medan du ligger kvar och funderar ett slag över hur ett sådant bi, som måste flyga hit och dit för att leta upp blommande växter, förmår att hitta hem igen. Dina tankar avbryts av ett surrande: biet närNeuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is stron
