We report the first measurement of charged particle elliptic flow in Pb-Pb collisions at root s(NN) p = 2.76 TeV with the ALICE detector at the CERN Large Hadron Collider. The measurement is performed in the central pseudorapidity region (vertical bar eta vertical bar < 0.8) and transverse momentum range 0.2 < p(t) < 5.0 GeV/c. The elliptic flow signal v(2), measured using the 4-particle correlati
The joint Swedish-Russian “Tundra Ecology-94” expedition during 1994 used the large Russian ice-breaking research vessel R/V Akademik Fedorov a platform and went along a coastline of 3500 km-from the Kola Peninsula 10°E to Kolyuchinskaya Bay 173°E. Radioactivity in air, seawater and sediment was explored at various locations along the route. The average of 7Be activity concentration in air over th
Neutral Pb clusters in the size range from a few tens of atoms up to similar to 100 atoms are studied using synchrotron-based photoelectron spectroscopy. The electronic structure is seen to differ increasingly from that of the solid when the cluster size decreases. The valence band narrows gradually - down to about one fifth of the solid-state band width at the smallest size of few tens of atoms.
Photovoltaics based on nanowire arrays could reduce cost and materials consumption compared to planar devices, but have exhibited low efficiency of light absorption and carrier collection. We fabricated a variety of millimeter-sized arrays of p-i-n doped InP nanowires and found that the nanowire diameter and the length of the top n-segment were critical for cell performance. Efficiencies up to 13.
We use a scanning gate microscope (SGM) to characterize one-dimensional ultra-thin (diameter approximate to 30 nm) InAs/InP heterostructure nanowires containing a nominally 300 nm long InAs quantum dot defined by two InP tunnel barriers. Measurements of Coulomb blockade conductance versus backgate voltage with no tip present are difficult to decipher. Using the SGM tip as a charged movable gate, w
This paper describes a pre-screening procedure that was carried out with a number of candidate Human-Machine-Interaction solutions in three different modes (visual, auditory and haptic) for the concepts of “safe speed and safe distance” (referred to as SASPENCE) of an Advanced Driver Assistance System (termed as ADAS). This procedure was performed simultaneously in two European countries, Sweden a
We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions coll
Glass sheets investigated regarding their Po-210 signal originating from indoor radon exposure will have a depth distribution down to about 100 nm. The geometrical probability of implantation into glass of glass-attached radon daughter activity in one alpha recoil event is 50%. A particulate layer on the glass sheet (dust, grease or other particles) will stop the alpha recoil nucleus partly or tot
This study maps reactions activated in peacekeeping personnel by life-threatening situations and explores how these reactions affect psychological functioning. In-depth interviews were carried out with 30 informants from the Swedish peacekeeping force serving in Bosnia between 1993 and 1995. All participants had experienced shooting incidents or other highly threatening events. Two models were for
The main objective was to assess knowledge, practices, and restrictions faced by young women regarding their menstrual hygiene. The views of adult women having young daughters were also included and both views were compared. In addition, the factors influencing the menstrual hygiene practices were also studied. The study was carried out during 2008 in Mumbai, India. The mixed methods approach was
Purpose: The purpose of this study is to develop a model for business process improvement that integrates national culture aspects to achieve sustainable performance improvement. Research questions: * How can national culture aspects be combined into a business process management model? * What is the difference between mapping methods? * How do they relate to each other and their intended scope?
I inköpsfunktionen för indirekt material och tjänster finns, för fallstudieföretagen, en kategori som ofta benämns Professionella tjänster eller dylikt. I denna övergripande kategori är konsult- och bemanningstjänster ofta underkategorier. Gränsdragningen mellan konsulttjänsterna och bemanningstjänster har dock visat sig otydliga och problematiken verkar främst finnas för konsult- och bemanningstjIn the purchasing funktion of indirect materials and services there is, for the case study companies, a category often referred to as Professional Services. In this overall category consultancy and temporary labour services are subcategories. Drawing the line between consultancy and temporary labour services has been proved unclear and the problems seem to mainly concern IT services. A proposal on
I mål om intrång i förfarandepatent finns särskilda svårigheter med bevisningen. Uppsatsens syfte är därför att utreda bevisproblematiken i mål om förfarandepatentsintrång. Utöver detta ska uppsatsen besvara frågeställningar kring huruvida ett processrättsligt medel kan lösa problemet och även hur man vinner framgång i mål utan att avslöja affärshemligheter. I mål där materialet är ofullständigtIn the case of infringement of method patent there is special difficulty regarding the evidence. The purpose of this essay is therefore to investigate the problem of evidence in cases of infringement of method patent. In addition, the essay is going to answer questions about whether a procedural legal remedy can solve the problem and also if it is possible to achieve success in such a case without
Detta examensarbete handlar om Building Information Modelling, även förkortat BIM, i järnvägsbranschen. BIM är ett relativt nytt arbetssätt som börjar implementeras allt mer men samtidigt används traditionell projektering. Med bakgrund av detta ämnar detta examensarbete undersöka i vilka uppdrag som det är mest lönsamt att implementera BIM. Frågeställningarna som togs fram var: ● Vilken ekonomisk This thesis deals with the subject Building Information Modelling (BIM), in the railway industry. BIM is a relatively new way of working that is beginning to be implemented more and more at the same time as traditional design is used. This study aims to investigate in which projects it is most profitable to implement BIM. The aim of this thesis to study is the following questions: ● What are the f
In recent years, the use of childcare especially in rich countries, has gone through a huge development. Well-established theories and previous research suggest that the social infrastructure has a positive impact on economic growth and that there is a positive relationship between childcare and equality. However, studies about how childcare affects economic growth are scarce. The aim of the study
Varje år drabbas ca 30.000 personer av stroke, vilket kan påverka såväl deras som de anhörigas hela vardag. Syftet var att undersöka hur anhöriga till strokedrabbade skattar sin upplevda aktivitetsbalans, samt att kartlägga eventuella olikheter beroende på demografiska faktorer. Metoden var en kvantitativ tvärsnittstudie med deskriptiv analysmetod. Datainsamling skedde genom enkäter med bedömnings
A voltage controlled galvanic simulator has been constructed for experiments on human balance. The aim is to gain knowledge about the human body's balancing behaviour and implementation for diagnostic purposes. The purpose is to stimulate the vestibular nerve in the inner ear, with a defined stimulus, measuring the resulting body sway, analysing the input and output signals with mathematical m
