Populärvetenskaplig sammanfattning: Inflödet av kosmiskt material till jorden har inte varit konstant sedan jorden bildandes, men det är svårt att studera hur inflödet förändrats eftersom meteoriter lätt omvandlas och förstörs på jordytan. En metod för att studera förändringar i inflödet av kosmiskt material till jorden är att titta på förändringar i halten kromit i sediment. Kromit är ett mineralMeteorites are easily altered in the oxygen-rich environment on the Earth surface. Fossil meteorites are thus uncommon and in the ones, which are found, almost all minerals are secondary. However, the spinel group mineral chromite is resistant to alteration and has successfully been used as a proxy for ordinary chondrites in sediment. The frequency and composition range of spinel group minerals in

Populärvetenskaplig sammanfattning: Det aktuella arbetet kompletterar Karolina Bjärnborgs masteruppsats från 2009 (Examensarbete Berggrundsgeologi Nr. 240) i samma ämne. Avsikten med arbetet är att testa och styrka hennes resultat med ytterligare prov och analyser. Syftet med båda projekten är att bestämma vilka malmmineral som finns och deras kemiska sammansättning i en kopparmineralisering i ZinThe Zinkgruvan Mining AB, situated in south-central Sweden in Örebro County, south-east of Åmmeberg, plans to expand their production on a massive, carbonate hosted copper-sulphide ore deposit, the Burkland Cu-mineralization in the eastern part of Knalla. At present mainly Zn-Pb-Ag are mined. The deformed Cu-mineralization belongs to the south-western Bergslagen ore province. It is of Paleoprotero

Under 1990-talet och fram till 2007 uppfördes uppskattningsvis 15 000 – 30 000 byggnader med en så kallad enstegstätad fasadkonstruktion. Konstruktionen innebär att husfasaden byggs i ett enda stycke, utan mellanliggande fuktdränerande luftspalt. Fram till 2007 ansågs konstruktionen vara mycket bra, men i början av 2007 uppdagades det att konstruktionen inte var så bra som branschen trott, utan snDuring the 1990s until 2007, approximately 15,000 to 30,000 buildings were built with a particular construction method known as External Thermal Insulation Composite System Walls, which means that the facade is constructed in one piece with no intervening air gap. Until 2007 the construction was considered to be appropriate, but in 2007 was found that it was not as good as people thought, and was

One of the cleanest ways of transporting goods is at sea. However, the emissions from ships increase and with a wider knowledge about the environmental consequences caused by the emissions, requisite regulations are needed. This thesis deals with air emissions of sulphate (SOx) - and nitrogen oxides (NOx). These emissions cause negative environmental effects both by direct pollution and by forming

Det sen-Triassiska massutdöendet (STM) var ett av de fem stora massutdöenden i Fanerozoikum och inträffade för omkring 201 miljoner år sedan. Forskningen är enig om att utdöendet orsakades av vulkanutbrotten associerade med bildandet av den Centralatlantiska magmatiska provinsen (CAMP), som är kopplade till uppbrottet av superkontinenten Pangea. De omfattande vulkaniska utsläppen av CO2 och SO2 leThe end-Triassic mass extinction (ETE) was one of the five big mass extinctions of the Phanerozoic and occurred ~201 Ma ago. Research agrees that the main triggering factor for the ETE was the eruptions of the Central Atlantic Magmatic Volcanic Province (CAMP), linked to the break-up of the supercontinent Pangaea. The large amounts of CO2 and SO2 released from the volcanic eruptions had a series o

Protected areas (PAs) embody a historical legacy of value contestation and human exclusion. While the rise of community-based conservation in the 1980s sought to reconfigure this mechanism by running a counter narrative arguing that biodiversity conservation and development were mutually reinforcing objectives, exclusionary PAs continue to maintain a strong position in the conservation discourse.

Asylrätten i ett EU-medlemsland består av ett samspel mellan nationell, EU-rättslig och internationell politik samt rättskällor. Dessa tre nivåer ger riktlinjer för hur en asylbedömning ska utföras och vad den ska innehålla. Grunden är att en som asylsökande måste anses uppfylla flyktingkriterierna som uppställs i Genèvekonventionen. Om beslutande myndighet anser detta vara fallet, erkänns personeIn an EU-member state, asylum law is the result of an interplay between national, EU and international policies and sources of law. All three levels give guidelines on the content of and how to carry out an asylum assessment. The basis for any asylum assessment is that the asylum seeker meets the refugee criteria put forth in the Geneva Convention. If this is found to be the case the person is rec

I mars 2015 nådde den globalt genomsnittliga koldioxidhalten 400 ppm för första gången på tre miljoner år. Därför satte den svenska regeringen, år 2017, upp målet att Sverige ska vara klimatneutralt år 2045. Samtidigt står den svenska byggindustrin för 18,1 miljoner ton växthusgasutsläpp, vilket motsvarar 19 procent av Sveriges totala utsläpp. Syftet med denna studie är att undersöka och analyserThe global average carbon dioxide concentration reached 400 ppm for the first time in three million years, in March 2015. This calls for drastic measures so in 2017 the Swedish government set up the goal of making Sweden climate neutral by 2045. Meanwhile, the construction sector in Sweden accounts for 18.1 million tons of green- house gases which is 19 percent of Sweden’s total emissions. The pur

We find ourselves in the midst of a remarkable technological revolution, with rapid advancements in fields such as artificial intelligence, robotics and information technology. Consequently, there is a pressing need for low-power technologies that are not reliant on continuous power supply. The field of spintronics aims to resolve this by coupling electric and magnetic properties. To pave the way

The polska, under lots of different spellings and titles, was the dominant music and dance repertoire in Sweden for nearly 300 years. The main purpose of this thesis has been to clarify some of the principal characteristics in both its dance and music forms. The thesis has both a historical and an ethnomusicological perspective and moves in the intersection between different types of traditional m

Health inequalities are a persistent and growing issue in different countries worldwide. Sweden, despite being one of the scandinavian countries with internationally recognized welfare system is no exception. The issue of health disparities and its increase among some groups, including those who are categorised as migrant have been acknowledged. Emergence of the COVID-19 pandemic, however, reveale

Endoscopic resection of colorectal polyps reduce morbidity and mortality from colorectal cancer (CRC).Endoscopic submucosal dissection (ESD) is a highly efficient and established method for treating advanced colorectal lesions in Asia, but experience of ESD in Western countries is limited. Large non-pedunculated colorectal lesions are prone to malignant transformation and it is therefore important

Olagligt, orapporterat och oreglerat (IUU) fiske är ett av de största hoten mot den marina biologiska mångfalden. Problematiken går hand i hand med farhågorna kring överfiske, något som har anammats av det internationella samfundet under de senaste två decennierna. Stater har uppmanats att på egen hand eller genom gemensamma initiativ, vidta åtgärder för att bekämpa IUU-fiske. Som en utav de störsIllegal, unreported and unregulated (IUU) fishing activities are currently considered to be one of the largest threats to the conservation of marine living resources and biodiversity. Thus, the international community have for the last two decades called upon States to take measures, individually or jointly, to combat IUU fishing. As an important actor on the global market, the European Union (EU)

With a discourse analytical approach, our main theory and premiss for this thesis was to examine how identity is created and reflected in the database Europeana, through election of objects made at national level. The focus of this thesis was primarily on the manufacturing process and the institutions and secondary on the user level. Our intention was to investigate whether it is possible to ident

Skyddet för den personliga integriteten har i takt med tekniska framsteg diskuterats inom en rad områden. Ett sådant område är arbetsrätten och specifikt arbetstagarens rätt till sin personliga integritet. Att dokument överförs till digital form samt att kommunikation flyttas från telefon och brev till e-mail gör det mer praktiskt möjligt för arbetsgivare att kontrollera sina arbetstagare än någonAs technology progress the right to personal integrity has been discussed in several areas. One of those areas is labour law and specifically the employee’s right to personal integrity. As communication becomes more and more digital it has become more practical for employers to monitor their employees. The question regarding employees’ right to protection for their personal integrity is, despite

Den vattenrättsliga regleringen av vattenkraft växte fram i början av 1900-talet för att hantera den stora utbyggnad av vattenkraft som följde industrialiseringen. Den miljörättsliga regleringen av vattenkraft kom dock först vid införandet av MB år 1998, en utveckling som löpt parallellt med en växande miljörättslig reglering inom EU. MB ställer omfattande krav på verksamhetsutövare ur miljöhänsynThe legislation of hydropower emerged in the early 1900s to handle the large expansion of hydropower that followed industrialization. Actual environ¬mental demands were first placed on operators of hydropower after the introduction of the Environmental Code in 1998. The aquatic environ-ment is today one of Europe's most regulated areas and the EU Water Framework Directive set out concrete and

Audiovisual content is heavily prevalent in many modern societies. Film, in particular, is a favourite form of entertainment to many. Film is by nature both multimodal and polysemiotic, employing the modalities of visual and auditive as well as the semiotic systems of language, gesture, depiction and music. Some audiences do not have immediate access to content using either the auditive or visual

I april 2019 utfärdades direktiv 2019/790, mer känt som DSM-direktivet.
