During 2007, a legal reform in Sweden took place, this change led to complications in interpreting the needs of individuals and the application of the laws by the governing social authorities. The aim of the thesis is to explore the underlying norms that influence social workers interpretation of young offenders needs, aged 15 to 17 years, and if the interpretations are consistent. The aim was ach
In today´s society it seems to be increasingly hard to make long-term relationships last. Divorce statistics in Sweden show that almost half of the marriages today end in divorce (SCB, 2012). Why then is it so difficult to make love work? Are we just harder to please, or can the trend be understood on the basis of the modern society we live in, where self-fulfilment and individuality clash with th
A Bose-Einstein condensate is a type of gas consisting of one or more types of particles called bosons which are cooled to a temperature very close the absolute zero. Under these conditions the particles all start to occupy their lowest quantum state. Once in these states it is necessary to use quantum physics to describe the behaviour of the particles by the means of a wave function which describ
With the transistor being the workhorse in modern electronics it has been vastly improved since its invention. However, the previous go-to improvement method of scaling it down has reached a dead end. Power dissipation has become a large concern and is in need of a solution. In the pursuit of further improving the transistor structure and its performance new approaches are being evaluated. A very
The RF power amplifier is one of the most critical blocks of transceivers, as it is expected to provide a suitable output power with high gain, efficiency and linearity. In this paper, a 60-GHz power amplifier based on an injection locked structure is demonstrated in a standard 65 CMOS technology. The PA core consists of a cross-coupled pair of NMOS transistors with an NMOS current source. This st
Fynd vid brottsplatser av vävnadsprov som kan användas för DNA-profilering har fått en ökande betydelse vid såväl utredning av brott som i efterföljande rättsliga processer. Genom en kombination av förfinad genetisk teknologi och förbättrade möjligheter att via datoriserade register jämföra DNA-fynd från brottsplatser med tidigare insamlade DNA-profiler från kända eller misstänkta brottslingar kanThe securing at crime scenes of tissue samples that can be used for DNA-profiling is gaining increasing importance in criminal investigations, as well as in lawsuits. Thanks to the combination of refined genetic technologies and markedly improved means to compare DNA profiles detected at crime scenes with those stored in various forensic registries through computerized database searches, both Swed
Background and purpose: Stroke is one of the world’s most common diseases and the second leading cause of death worldwide. From 1996 to 2006 the treatment of acute ischemic stroke (AIS) was limited to intravenous fibrinolytic therapy; a treatment often associated with risk and insufficiency. In 2006, treating AIS by mechanical clot removal, known as thrombectomy, was approved by the U.S. Food and
The purpose of the numerical study was to investigate the influence of three different natural gas compositions on the combustion behaviour of an Advanced Environmental Vortex (AEV) burner. The flow conditions apply to the AEV burners installed in the Siemens gas turbine SGT-800. Numerical simulations were carried out using the software Chemkin 4. Ignition temperatures, adiabatic flame temper
The majority of the deaths when a fire takes place are due to the smoke. The fire gases can easily spread through the ventilation system if it is not properly designed and some safety measures are taken. The current legislation suggest as solution to install independent ventilation systems or smoke barriers. However, the new Swedish legislation will offer new possibilities base on smoke dilution
This report is a study on the effects pyrotechnically generated aerosols, PGA, has on electrical components and our health. Experiments were conducted in small and full scale at Lunds tekniska högskola and the Swedish rescue service’s school at Revinge. The experiments were conducted using only one type of PGA with exception for the full scale experiments in wich two types were used. The experimen
This thesis aim is to explore the role of Ukraine on Eurasia ‘chessboard’ on which the struggle for power has being played, since the continent started to act politically, up to day. Master thesis elaborate on the introduction and theoretical framework that investigate the role of Ukraine as a critically important geopolitical pivot whose importance is derived not from it power and motivation but
Measurements of four-lepton differential and integrated fiducial cross-sections in events with two same-flavour, opposite-charge electron or muon pairs are presented. The data correspond to 139 fb−1 of s = 13 TeV proton-proton collisions, collected by the ATLAS detector during Run 2 of the Large Hadron Collider (2015–2018). The final state has contributions from a number of interesting Standard Mo
AimImpaired vibrotactile sense, mirroring diabetic peripheral neuropathy, is present among children and adolescents with type 1 diabetes. This study aims to re-examine the vibrotactile sense of paediatric type 1 diabetes subjects in order to evaluate any alterations in the vibrotactile sense over time.MethodsA VibroSense Meter I device was used to determine the vibrotactile perception thresholds (
The conversion of technical lignin into valuable chemicals is important for the complete utilization of lignocellulose. The kraft process dominates the pulp industry, and large amounts of kraft lignin are produced worldwide. However, the complexity of lignin limits its valorization. In this study, a kraft lignin, Indulin AT, was depolymerized under base conditions, and the effects of substrate loa
