Using an enriched sample in a high temperature scattering cell we have determined the hyperfine structure of Te 125 in the 5 p 3 6 s 5 S 2 level of the Te I spectrum by the optical double resonance and level crossing techniques. For the magnetic dipole interaction constant a we obtain | a (5 p 3 6 s 5 S 2 Te 125 )| = 1 010.4 (1.3) MHz The spin density at the nucleus, calculated using this value, i

Objectives: To analyze the accumulated fees connected with root filling, permanent coronal restoration and follow-on treatment charged by Swedish dentists over a 10–11-year follow-up period. Furthermore, analyzing these fees with reference to the type of restoration, tooth group, and the root-filled teeth which survived compared to those requiring extraction. Material and Methods: In 2009, the dat

The inclusive top-quark-pair production cross section σtt¯ and its ratio to the Z-boson production cross section have been measured in proton–proton collisions at s=13.6 TeV, using 29 fb−1 of data collected in 2022 with the ATLAS experiment at the Large Hadron Collider. Using events with an opposite-charge electron-muon pair and b-tagged jets, and assuming Standard Model decays, the top-quark-pair

Syftet med denna studie var att undersöka hur en gruppinsats för unga flickor med högfungerande autism fungerade och upplevdes av deltagarna och deras vårdnadshavare. Gruppinsatsen bestod av en integrering av metoder hämtade ur Acceptance and commitment therapy (ACT), compassionfokuserad terapi (CFT), dans och yoga och avsåg att förebygga psykisk ohälsa hos deltagarna. Studien genomfördes genom ob

I juli 2014 föreslog Europakommissionen ett cirkulärt ekonomipaket som skulle bidra till att göra EU mer resurseffektivt genom att recirkulera resurser in i det ekonomiska systemet. En cirkulär ekonomi syftar till att tillvarata värdefulla naturresurser samtidigt som man motverkar behovet av att extrahera nya. Det föreslagna paketet innehöll bland annat ändringar i avfallsdirektiven, höjda återvinIn order to become more resource efficient and circulate resources back into the economic system, the European Commission adapted a circular economy package in 2014. This is in line with the idea of a circular economy. This study investigates how the legislative proposal to review recycling and other waste-related targets in the EU, which was a part of the proposed circular economy package, would

Purpose There is a need to find a quick way to assess the impacts of the growing amount of globally manufactured and emitted chemical substances. This paper evaluates the use of Quantitative Structure Activity Relationships (QSAR) for predicting environmental effects of plastic additives in Life Cycle Impact Assessment (LCIA). It also evaluates the impact on so called Characterization Factors (CF)

The last glacial period is characterized by a number of millennial climate events that have been identified in both Greenland and Antarctic ice cores and that are abrupt in Greenland climate records. The mechanisms governing this climate variability remain a puzzle that requires a precise synchronization of ice cores from the two hemispheres to be resolved. Previously, Greenland and Antarctic ice

The Patient Protection and Affordable Care Act (PPACA) has been debated by both Republicans and Democrats. In spite of clearly expressed opinions, the normative ideas behind the arguments are not evident. My assumption is that the political agenda is normatively framed. Depending on what values a politician builds his or her conception of the world certain aspects of an issue are highlighted at th

Uganda, along with a number of other African states, is a state struggling with the task of bringing together a vast range of ethnic minority groups into one nation-state decided by geographical borders drawn by colonial masters Britain during imperialism. The effects of these colonial decisions and policies are widely known to having plagued the native population during the course of history. Thi

A search for exotic decays of the Higgs boson H into new scalar or pseudoscalar particles that subsequently decay into b-quarks is presented. The search considers ZH production with several decay scenarios for the Higgs boson; first to a pair of identical scalars, H → 2a → 4b, second to a pair of scalars with different masses (ma1 < ma2), either directly, H → a1a2 → 4b, or via a longer decay chain

Time-of-flight mass-spectrometry (TOF-MS) measurements of 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([EMIM][OTF]) vapors have been conducted in order to gain insight into the VUV (vacuum ultraviolet) absorption thresholds. The experimental data were interpreted with hybrid density-functional theory (DFT), time-dependent DFT (TD-DFT), and several flavours of many-body perturbation theor

The current crime debate in Sweden surrounds the overarching issue of criminal networks and children’s exploitation by them. In Sweden, younger children are getting involved in serious criminality, carrying out offences for criminal gangs such as murder and aggravated weapons crimes, which has sparked the government’s interest in possible changes to the youth criminal justice system. One of those

Bismuth-based compounds, such as Bi1-xSbx or Bi2Te3, have outstanding electronic properties especially for advanced quantum devices. However, the potential of low-dimensional group V-Bi materials is largely undetermined. Here, we report the experimental realization of a two-dimensional (2D) BiAs layer with giant Rashba spin splitting, grown on an InAs(111)B substrate via molecular beam epitaxy. AR

Nanochains (NCs) made up of a one-dimensional arrangement of magnetic anoparticles (NPs) exhibit anisotropic properties with potential for various applications. Herein, using a novel self-assembly method we directly integrate single NCs onto desired substrates including devices. We present a nanoscopic analysis of magnetization reversal in 1D linear NP arrays by combining x-ray microscopy, magnet

The associated production of Higgs and W bosons via vector-boson fusion is highly sensitive to the relative sign of the Higgs boson couplings to W and Z bosons. In this Letter, two searches for this process are presented, using 140  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV recorded by the ATLAS detector at the LHC. The first search targets scenarios with opposite-sign couplings o

I denna avhandling undersöks opinionsundersökningens introduktion i Sverige under mitten av 1900-talet. Fokus ligger på Svenska Gallupinstitutet AB, som 1941 etablerades som landets första opinionsinstitut och som introducerade den urvalsbaserade enkätundersökningen som ett nytt medium genom vilket den allmänna opinionen kunde representeras. De hade i princip monopol på området till 1950-talets miThis thesis examines the introduction and impact of opinion polling in Sweden during the mid-twentieth century, focusing on the activities of the Swedish Gallup Institute (Svenska Gallupinstitutet). Established in 1941 as the country’s first polling organization, the institute introduced sample surveys as a new means of representing public opinion and had a near-monopoly on polling until its decli

The unprecedented military and economic support provided by non-participating States to Ukraine following the Russian aggression has reignited the debate surrounding the law of neutrality. The law of neutrality, first codified in the Hague Conventions of 1907, defines the legal relationship between States involved in an international armed conflict (IAC), known as belligerents, and States not taki
