It has for long been known that dark matter must exist in our universe. Despite massive efforts to detect dark matter, its constituents remain a mystery. One strategy to unveil this mystery is to produce dark matter by colliding Standard Model particles. The most common signature of dark matter production is an excess of missing transverse energy, MET. Such an event would be very rare, which is wh
Denna uppsats syftar till att analysera förutsättningarna för att förbjuda förflyttningar av asylsökande inom det gällande Dublinsystemet, samt hur kompatibelt den europeiska kommissionens förslag för en Dublin IV Förordning är med mänskliga rättigheter. Dublinsystemet har till syfte att fördela skyldigheten att hantera asylansökningar mellan medlemsstaterna inom EU till en ansvarig medlemsstat. This thesis aims to analyse the prohibitions of transfers of asylum seekers in the Dublin System, and how compatible the Commission’s Proposal for a Dublin IV Regulation is with human rights law. The Dublin System is meant to allocate responsibility between Member States regarding asylum applications. After the responsible Member State has been decided according to certain criteria, the asylum see
This paper investigates receptive knowledge of English lexical collocations among Swedish high school students. The study tests the claim that L2 (second language) learners of English have a low level of collocational competence and tend to recognise high-frequent collocations more than low-frequent since the former have been encountered more. The target items for this study consisted of 40 colloc
Svensk och dansk standard skiljer sig åt vid beräkning av pålars bärförmåga i lermorän, där den svenska metoden i tidigare undersökningar har konstaterats mest konservativ. En av anledningarna till detta är att spetsens inverkan på bärigheten beaktas vid dimensionering enligt dansk standard, men bortses från när svensk standard tillämpas. Svensk standard appliceras idag med utgångspunkt i samma me
En slitsmur är en geokonstruktion som utförs genom att paneler platsgjuts med marken som form. Panelerna bildar tillsammans en samverkande vägg. Tekniken är vanlig utomlands men fortfarande relativt ovanlig i Sverige. Behovet, och därmed intresset, av slitsmurar i Sverige växer dock i takt med förtätningen av städer och infrastrukturprojekt som kräver djup schaktning och anläggning. Kraven på låg A diaphragm wall is a retaining wall which is produced as a cast in-situ concrete wall. The ground itself acts as formwork. The technique is widely used internationally but it is comparably still a rare technique in Sweden. However, the need, and therefore interest in Sweden for diaphragm walls is growing as the number of inner city infrastructure projects requiring deep excavations increases. The
Havsnivån stiger till följd av den globala uppvärmningen. Fastigheter kommer att drabbas av översvämningar och stora fastighetsvärden kommer att påverkas. Länsförsäkringar beslutade 2018 att sluta försäkra nybyggnation av bostäder inom områden som löper risk för översvämning där länsstyrelsen har avrått från byggnation. Flera kommuner planerar för skydd av befintlig bebyggelse, men examensarbe
Meteoriter är indelade i tre huvudsakliga klasser, järn, sten-järn och stenmeteoriter. Stenmeteoriterna är vidare indelade i primitiva akondriter och kondriter. Kondriterna är vidare indelade i fyra grupper, enstatitkondriter, vanliga kondriter, kolrika kondriter och rumurutikondriter. Dessa grupper är i sin tur indelade i undergrupper, enstatitkondriterna är indelade i EH (hög FeO-halt) och EL (lMeteorites are divided into three basic groups, iron, stony-iron and stony meteorites. The stony meteorites are further divided into primitive achondrites and chondrites. The chondrite class is divided into different groups, enstatite chondrites, ordinary chondrites, carbonaceous chondrites and rumuruti chondrites. The enstatite chondrites are divided into EH and EL, which stands for enstatite hig
Populärvetenskaplig sammanfattning: Jag har studerat ungefär 450 miljoner år gammalt material från Cincinnati-området i USA. Materialet består av stenplattor av olika storlek, med fossila rester av olika havslevande organismer. Under tidsperioden Ordovicium låg den amerikanska kontinenten vid ekvatorn och dess inre täcktes av ett hav. Just i området kring Cincinnati avlagrades i detta epikontinentThe study aims to reconstruct the palaeoenvironments and faunas from six different localities in the area of Cincinnati, USA. The Upper Ordovician consists of limestones with intercalating mudstones. The faunas are rich and very diverse. The taxonomic composition and taphonomic indications are briefly described. The palaeoenvironment and faunal communities are reconstructed and compared to Bretsky
Populärvetenskaplig sammanfattning: I försök att producera kontinuerlig data över förändringar i jordens magnetfält använder man sig ofta av sjösediment. Magnetiska mineral, eroderade från den kringliggande berggrunden, förekommer ofta i sjöar. Koncentration av dem beror på hur rik bergrunden är på den typen av mineral, t.ex. magnetit. När de magnetiska mineralen faller till botten riktar de in siThe pseudo-Thellier technique was applied to recover relative palaeointensity (PT-RPI) estimates from four core sections, each 2 m in length, obtained from Lake Gościąż, Poland. The varve chronology from Lake Gościąż, originally constructed by Tomasz Goslar, was transferred to the sediment sequence. The chronology was extrapolated to cover the upper parts containing a less pronounced varve structu
Cellular communication is constantly evolving; currently 5G systems are being deployed and research towards 6G is ongoing. Three use cases have been discussed as enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC). To fulfill the requirements of these use cases, new technologies are needed and one enabler is massive mult

Title. Contested streets. Political marches in Stockholm, 1887–1920.Abstract. Repertoires of contention change. It is clear that during the 19th and early 20th century, swedes learned to stage marches to make political claims, something that was virtually unknown in Sweden before the mid-19th century. At first, the oligarchy that held power in Sweden mostly accepted political marching in the stree

Prosperous cities have constantly changed and their ability to adapt to contemporary commercial demands has always been rewarded, but this may no longer be the case. Delhi residents are now paying a high price for this endeavor with schools closed due to toxic air caused by high levels of carbon dioxide. Although previous urban transformations by drastic demolition had an insignificant climate imp
Choir singing has been suspended in many countries during the Covid-19 pandemic due to incidental reports of disease transmission (Hamner et al. Citation2020). The mode of transmission has been attributed to exhaled droplets, but with the exception of a study on tuberculosis from 1968, there is presently almost no scientific evidence of increased particle emissions from singing (Loudon and RobertsChoir singing has been suspended in many countriesduring the Covid-19 pandemic due to incidental reportsof disease transmission.
