Crystal Plasticity Finite Element Modelling of Tin Crystals Using Phase Fields

Tin whiskers have long caused issues to electronic components and made the subject of many articles. According to NASA the oldest reports concerning whiskers date back to the 1940's. The whiskers are single-crystals growing from, for example electronic components. Despite the long history of tin whiskers the actual cause of their growth is still unknown. The hypothesis held by the author is th

Using gallium nitride nanowires as STM probes

Gallium nitride (GaN) nanowires grown using catalyst-free metal organic vapor phase epitaxy were used as scanning tunneling microscope (STM) probes. The probes were prepared by placing a GaN nanowire on a tungsten STM probe using a nanomanipulator in a scanning electron microscope (SEM) and welding them together using an electron beam induced platinum deposition. STM imaging was performed on indiuA microscopy field known as Scanning Probe Microscopy (SPM), uses various methods to get a picture of a sample surface down to such a small scale that individual atoms can be observed. One particular method to perform such microscopy uses the phenomena of quantum tunneling rather than using visible light. This method is called Scanning Tunneling Microscopy (STM) and the way it works is extremely d

"We Are the Land and the Land Is Us" - Analyzing the Construction of Sami National Identity in Sami Political Discourse on Land and Natural Resources

The collective fight for self-determination among indigenous peoples around the world has made headlines over the past few years. The exploitation of indigenous territories by settler-states has revived nationalist feelings among the groups, including the Sami, whose territories spread across four states. This thesis aimed to explore how Sami national identity is constructed, shaped and promoted

Framtiden för Helsingborgs godsbangård

Området Ramlösa station och Helsingborgs godsbangård innefattar bland annat resecentrum, rangerbangård, tågdepåer och kombiterminal för att nämna några. Utöver det är området en del i stadsförnyelseprojekt H+ som ska omvandla en miljon kvadratmeter till en mer blandad stad, för att möta framtidens behov. Inom området har aktörer tillkommit, försvunnit och behovet har förändrats över tid. Det har o

From TV Buddha to Robotic Monk:A Transcultural Question Concerning Techno-Buddhism

From the beginning of the 21st century, there has been a tendency to hybridize Buddhism with modern technology, which embodies rich ambiguities. At the conference AI World 2016, a robotic monk Xian’er with artificial intelligence(AI) premiered in China and was claimed as the icon of the harmony of techno-Buddhism. This paper will explore the ambiguity of Xian’er – why and how the harmony comes int

Purification of Chlamydia trachomatis Ribonucleotide Reductase delta248

Målet med detta arbete var att rena fram proteinet Chlamydia trachomatis ribonucleotide reductase R1 Δ248. För att göra detta effektivt, med en så liten förlust av proteinet som möjligt under processen, så krävs kunskap om proteinets egenskaper. Med vetskapen att denna mutant, som saknar de första 248 aminosyrorna jämfört med den icke-muterade varianten, enbart har en ATP-kon medan den icke-muteraThe enzyme Ribonucleotide Reductase (RNR) reduces ribonucleotides (NTPs) to deoxyribonucleotides (dNTPs), which are then used as building blocks in the synthesis of DNA. In this thesis are reported the expression and purification of a mutant version of Chlamydia trachomatis Ribonucleotide Reductase protein R1 , called Chlamydia trachomatis Ribonucleotide Reductase protein R1 Δ248. The R1 subunit o

Identifiering av riskområden för extremer av markfuktighet med Soil Topografic Index : jordbruksmarken i Helsingborgs kommun i nutida och framtida perspektiv

STI (Soil Topografic Index) är ett hydrologiskt index som beskriver markfuktigheten i ett landskap. Då indexet är baserat på de relativt konstanta faktorerna topografi, jordens textur och jorddjup beskriver det ett generellt markfuktighetsmönster. Indexet applicerades på jordbruksmark i Helsingborgs kommun för att få kunskap om vilka områden markfuktigheten tenderar att vara låg eller hög. Vid extThe index STI describes water flow path in a landscape. Whit the help of STI it´s possible to detect areas where the soil moisture is expected to be very high or low. When comparing the result of the STI for the chosen study-area with interviews for farmers in the same area, where was a similarity between which areas the STI identified as risk for high soil moisture and which areas the farmers ide

The impact of Medicaid expansion in 2014 on prescription second-generation antidepressant utilization in Washington State: An interrupted time series analysis

Background Depressive disorders, specifically major depressive disorder (MDD), is predicted to become the leading cause of disease burden worldwide by 2030. In the United States, MDD is already the leading cause of disability. Yet, less than 50 percent of US adults diagnosed with a mental disorder seek treatment, often due to lack of health coverage or affordability. In 2014, the Affordable Care A

Between Contentment and Curiosity: The Hybrid Femininities of Young Bedouin Women in South Sinai

The drastic changes in infrastructure and arrival of luxury tourism to South Sinai has brought the global world at the doorstep of the region’s nomadic bedouins. The ever-expanding global influence has given birth to a generation of young bedouin women who absorb the surrounding new ideals, behaviors and understandings, blending them with their tribal culture. This has created identity hybridities

Climate Change and Precipitation Variability Influence on the Greenland Ice Sheet

Climate changes have a large impact on precipitation patterns and precipitation variability change. With this in mind, precipitation over Greenland is studied. This is done for present day precipitation model data from 1991-2010 compared to future model simulations of precipitation for 2081-2100. Furthermore, precipitation drives Surface Mass Balance (SMB), which is the sum of accumulation and the
