We focus on exclusive production of neutral technipion (pi) over tilde (0) in pp collisions at the LHC, i.e. on pp -> pp (pi) over tilde (0) reaction. The dependence of the cross section on parameters of recently proposed vector-like Technicolor model is studied. Characteristic features of the differential distributions are discussed. For not too large technipion masses the diphoton decay channel
This study deals with the issue of how music can affect the religious experience of people who sing in choirs in the Church of Sweden. It is established that music plays a great importance in people’s every-day lives, and that it has various effects on us, for instance how it can soothe a person who is agitated or the way it can induce fright, compassion, anger or happiness. Music occupies a large
Sammanfattning Syftet med denna uppsats är att undersöka hur EU-rätten påverkar den svenska arbetsrättsliga modellen, särskilt arbetsgivarens generella informationsplikt och om Sverige har levt upp till de krav som EU-rätten ställer vid införlivandet av direktiv 2002/14/EG om införlivande av allmän ram för information till och samråd med i Europeiska gemenskapen, gällande nationella förhållanden. The purpose of this paper is to examine how EU law influences the Swedish labour law model, particularly the general obligation of employers to provide information and concerning, whether Sweden has lived up to the requirements imposed under EU law regarding the implementation of the directive 2002/14/EC establishing a general framework for informing and consulting employees in the European Commun
The future opportunities for high-density QCD studies with ion and proton beams at the LHC are presented. Four major scientific goals are identified: the characterisation of the macroscopic long wavelength Quark-Gluon Plasma (QGP) properties with unprecedented precision, the investigation of the microscopic parton dynamics underlying QGP properties, the development of a unified picture of particle
Principal investigator: Professor Malin Malmsjö This project focus on evaluating and optimizing PA imaging as a method to detect and outline skin tumors. We are investigating the PA spectral signature of different tumor cells to enable automatic measurement of the tumor borders, and test the developed method in the clinical setting, ultimately developing PA imaging into a diagnostic tool for skin

Popular Abstract in Swedish Akut koronart syndrom (AKS) är den största folkdödaren i väst idag. Trots välutbildade läkare och bra diagnostiska verktyg så är det forfarande svårt att ställa en diagnos tidigt på sjukhusens akutavdelningar. I den här avhandlingen undersöker vi möjligheter att i ett tidigt skede förutsäga AKS med hjälp av maskininlärning. Främst användes logistiska regressionsmodellerAcute coronary syndrome (ACS) is the biggest people killer in the western world today. Despite well trained physicians and reliable diagnostic tools, diagnosing ACS early in the emergency departments (ED) remains a challenge. In this thesis we used machine learning, via logistic regression models and artificial neural network ensembles, to investigate the possibility of predicting ACS at an early
Mayafolket har levt i över 3000 år på Yucatánhalvön, i Mellanamerika. I det område som idag tillhör Mexico, Guatemala och Belize, lever Mayakulturen kvar. Precis som människor har gjort i alla tider, så har även Mayafolket tittat upp mot natthimlen och ställt sig frågan: vad gör vi här?I alla Mayafolkets byggnader vördades tid som någonting heligt. Redan för hundratals år sedan föreställde sig MayThe Mayans have lived in central America for over 3000 years. In a region that today belongs to Mexico, Guatemala and Belize the Mayaculture lives on. Throughout history the Mayans have observed the skies above, made up stories and legends and looked to the skies for answers.In a feast of colours and sounds, Mayan Archaeoastronomy: Observers of the Universe makes a tour of 6 Mayan temples: San Ger
Installation of heat recovery system in multi-family houses - A comparison between a central system and an individual system. Energy- efficiency of buildings is a popular subject of discussion. If we are going to reduce the energy consumption in our buildings we need to install more effective ventilation systems that utilize the heat in the exhaust air. Exhaust and supply air ventilation with heat
The quantum cascade laser (QCL) is a semiconductor heterostruc- ture using inter sub-band transitions to generate stimulated emission. The quantum cascade detector (QCD) is a similar to the QCL, but the heterostructure is tailored to absorb radiation and give a read-out current. In this work, three planned or realised QCL:s and two QCD:s have been simulated and analysed using a program based on th
Den krypterade kommunikationstjänsten Encrochat har förut använts i stor omfattning inom kriminell verksamhet. Detta fram till att franska polismyndigheten lyckades dekryptera chattarna och komma åt materialet. Sedan dess har svenska brottsbekämpande myndigheter fått ta del av materialet. I uppsatsen förklaras vad Encrochat är och hur samt med grund i vilken lag materialet har inkommit till svens
Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster. Theoretical studies have indicated that some of these clusters can
Offentlig upphandling är ett ämne där många har synpunkter och ämnet har också debatteras frekvent i media och inom den juridiska diskursen. Inte minst handlar det om miljökrav där också fler och fler använda sig ut av dessa krav i sina upphandlingar. Ett samordnade och stödjande arbete med råd om hur man kan ställa miljökrav har bedrivits, inte minst inom ramen för Miljöstyrningsrådet (MSR). Sam
We have for the first time identified the early stellar disk in the Milky Way by using a combination of elemental abundances and kinematics. Using data from APOGEE DR17 and Gaia we select stars in the Mg–Mn–Al–Fe plane with elemental abundances indicative of an accreted origin and find stars with both halo-like and disk-like kinematics. The stars with halo-like kinematics lie along a lower sequenc
