Populärvetenskaplig sammanftaaning: För 65 miljoner år sedan slog en extraterrestrisk kropp ner på Yucatán-halvön i södra Mexico. Nedslaget orsakade ett av de största massutdöendena i historien, då bland annat dinosaurierna dog ut. Nedslaget kan ha varit en följd av ett tillfälligt ökat asteroidflöde i inre solsystemet som orsakats av att en jätteasteroid i asteroidbältet mellan Mars och Jupiter bAn impact crater is the result of a collision between a large and a smaller body. On Earth most of the cratering record has been erased because of tectonic processes and weathering. The Moon, however, displays a nearly complete record of impact events over the last 2 Gyr, and evidence of impact cratering events nearly 4 billion years old. The same family of impactors is responsible for the formati

Abstract The breeding season of the natterjack toad (Bufo calamita Laurenti 1768), a „prolonged breeder“, lasts up to three months in southern Sweden. However, not all reproducing individuals are present at the breeding sites during the full time span. Thus, some populations can be sub-divided into temporally isolated subpopulations using earlier or later periods of the season for reproduction. T

Abstract The pharmaceutical industry is currently facing a high clinical attrition rate. In order to prevent the late-stage clinical failure, many investigations on compound quality and drug-likeness of compounds have been carried out. It has been widely accepted that molecular size and lipophilicity plays an important role in compound quality. Many attempts have been done to find out other fact

The increased possibilities for geographical separation of the production process have given rise to a growing interest for trade in intermediate goods in the international trade literature. Thanks to trade in parts and components, but also in services and other immaterial products, developing countries have been able to enter the global trade scene to a greater extent than before. This paper anal

This study deals with the acquisition of negation in French second language for Swedish speakers in written production. In fact, numerous studies have been dedicated to this subject, investigating learners with different first languages. However, these studies often examine the acquisition of negation in oral language. Given the difference between speaking and writing in French language, it is als

The Earth System Governance open science conferences are an environmental-political happening in which researchers from all over the world present their studies. Approximately 400 researchers submit an abstract each conference, half of which are accepted. The purpose of this thesis is to investigate which variables increase or decrease an abstract’s probability of getting accepted. The Focus here

With the proliferation of Long Term Evolution (LTE) networks, many cellular carriers are embracing the emerging eld of mobile Voice over Internet Protocol (VoIP). The robust header compression (RoHC) framework was introduced as a part of the LTE Layer 2 stack to compress the large headers of the VoIP packets before transmitted over LTE IP-based architectures. The headers, which are encapsulated Re

Methodology: The thesis has been conducted with a mixture between a systems approach and an actors approach. An abductive research method has been chose

Många forskare lyfter fram fenomenet att gränserna mellan intern och extern kommunikation suddas ut. Det är däremot tämligen outforskat vad detta får för betydelse för organisationers kommunikation, vilket denna studie tar avstamp i. Ett exempel är att medarbetare genom dagens kommunikationsmöjligheter kan lyfta en organisations interna sakfrågor i digitala diskussionsarenor. Syftet med uppsatsen Many researchers express that the boundaries between internal and external communication are being blurred. However, since few studies suggest what communicative implications this has for organizations, our study explores a highly under investigated topic. One way in which the blurring of boundaries is expressed is that employees can bring forth internal organizational issues in online issue arena

EUs anslutning till Europakonventionen har varit föremål för diskussion ända sedan slutet av 1970-talet. På grund av bristande rättslig grund i fördragen, har anslutning dock inte varit möjligt förrän ikraftträdandet av Lissabonfördraget år 2009. Artikel 6(2) FEU föreskriver nu en skyldighet för EU att ansluta sig till konventionen under förutsättning att avtalet om Unionens anslutning avspeglar nAccession of the EU to the ECHR has been subject to discussion since the late 1970s. Due to a lack of legal basis in the treaties, accession has not been possible until the entering into force of the Treaty of Lisbon in 2009. Article 6(2) TEU now stipulates an obligation for the Union to accede to the Convention under the condition that the agreement relating to the accession makes provisions for

Research show that human trafficking is one of the fastest growing criminal industries today, after narcotics and illegal arms trade (The Polaris Project 2014). The most common victims of human trafficking are stated to be women and children (UNODC 2012). According to the UNICEF (2007), 1,2 million children are estimated to be exposed to trafficking for various exploitative purposes every year aro

This research examines the introduction and diffusion of biochar as a soil amendment and biochar producing stoves in Embu County, Kenya, together with its related socio-economic potentials and challenges. The area has seen rapid rates of deforestation together with declining soil fertility during the last couple of decades. Biochar as a soil amendment and biochar producing stoves offers a viable s

Häktning är ett straffprocessuellt tvångsmedel som används i brottsmål för att underlätta polisens och åklagarens utredning av ett misstänkt brott. Häktning innebär att en person misstänkt för ett specifikt brott får sina rättigheter inskränkta med laga stöd. Häktning är en frihetsberövande åtgärd som används trots att den misstänkte personen ännu inte är dömd. De särskilda häktningsgrunder som enThe use of detention in a remand prison is a tool of pre-trial supervision in order to facilitate the investigation of an alleged crime. The grounds for using detention in a remand prison for a person suspected for an alleged crime is the risk of the suspect continuing its criminal acts, the flight risk of the suspect and the risk of the suspect having a unduly effect on the investigation of the a

Green technologies are essential to the development of sustainable economy and environmental protection. Stimulating innovation in green technologies requires environmental policies, regulations, public awareness, and more importantly intellectual property protection such as patents. This thesis explores the significance of patents in the green innovation process, and how patents affect the firms’

This study aims to investigate and map the current production, planning, and scheduling processes within the Swedish healthcare, as well as develop a digital solution. This is done through a user-centered design process, with the goal of designing a d

Memory impairment and prominent hippocampal atrophy are the most recognisable features of Alzheimer’s disease (AD). It has been known that hippocampus and surrounding medial temporal lobe (MTL) structures support memory processes. However, specific function of each MTL subfield remains to be elucidated. Not all MTL subfields are uniformly affected by AD pathology and the spread of AD pathology fol

Uppsatsen är en fallstudie över den svenska implementeringen av PSI-direktivet.4 Direktivet skulle enligt artikel 12 direktivet vara genomförd i svensk rätt senast den 1 juli 2005.

Sedan grundandet har EU vuxit från sex till tjugosju medlemsländer, under totalt sju utvidgningsomgångar. För närvarande är fem länder kandidater för medlemskap: Montenegro, Serbien, Albanien, Nordmakedonien och Turkiet. Kosovo och Bosnien och Hercegovina är potentiellaEnlargement, the process whereby countries join the European Union (EU), has had a key role in the Union’s development. Since its founding, the EU has grown from six to twenty-seven Member States, in a total of seven enlargement rounds. Currently, five countries are candidates for membership: Montenegro, Serbia, Albania, North Macedonia and Turkey. Kosovo and Bosnia and Herzegovina are recognised

Ryggmärgsvätskan, eller cerebrospinalvätskan, är en klar, plasmaliknande vätska som fyller ventriklarna (hålrum i hjärnan) och rummen innanför kraniet och ryggraden. Ryggmärgsvätskan hjälper till att upprätthålla immunförsvaret och balansen av viktiga ämnen. Det agerar även som transportsystem för slaggprodukter ut ur det centrala nervsystemet för lösa ämnen som inte kan passera genom blod-hjärnbaBackground The cerebrospinal fluid (CSF) is involved in several diseases and patho- physiological states, such as Alzheimer’s disease and hydrocephalus. Previous studies CSF dynamics in the brain show that the flow of the CSF depends on cardiac pulsation, time of day and respiration. Methods In this thesis, the validity of using real time phase contrast MRI in order to study CSF flow is evaluated
