We present a study of high-order-harmonic generation (HHG) assisted by extreme ultraviolet (XUV) attosecond pulses, which can lead to the excitation of inner-shell electrons and the generation of a second HHG plateau. With the treatment of a one-dimensional model of krypton, based on time-dependent configuration interaction singles (TDCIS) of an effective two-electron system, we show that the XUV-
In this letter, the fading statistics of wireless channels in high-speed railway cutting scenarios are characterized based on measurements. A multiple scattering model called second-order scattering fading (SOSF) is used to model the small-scale fading considering the influence of cuttings and bridges. The SOSF model can offer the possibility of analytical estimation for different fading severitie
Diagnostic reference levels are the main and the most effective tools of optimization of the radiation protection of patients from medical exposure. Diagnostic reference levels should be established based on theresults of dedicated dose surveys, allowing evaluating typical patient dose distributions in a selected dose quantity for the selected X-ray examinations. The aim of the current study was t

På grund av sin natur behövdes kompletterande bestämmelser införas i svensk nationell On January 11th, 2015, Directive 2011/99/EU of the European Parliament and of the Council of 13 December 2011 on the European protection order and Regulation (EU) No 606/2013 of the European Parliament and of the Council of 12 June 2013 on mutual recognition of protection measures in civil matters entered force in the European union. Due to the complex nature of the regulation, supplementary legis
När jord avlastas kan denna svälla, något som kan ge tryck och således skador på konstruktionsdelar som har kontakt med den svällande jorden. Det är därför av stor vikt att ha kunskap om hur jorden beter sig vid avlastning och detta undersöks vanligtvis i geotekniska laboratorier. I detta examensarbete studerades svällningen av lera, erhållen från Göteborgområdet, som avlastas med hjälp av en modiThe unloading modulus, together with the permeability, are responsible for the swelling process of a soil that is subjected to unloading. Studies to examine the unloading modulus of clay has previously been performed and several relationships describing this parameter has hence been developed. The methods to study the unloading modulus has previously been both laboratory studies and field measurem
Idag kopplas allt fler enheter upp på Internet, vilket effektiviserar såväl enhetshantering som kommunikation mellan enheter. I hemmiljöer kan användare styra enheter genom att förse dem med beskrivande namn, som till exempel "högtalare vardagsrum". Så länge antalet enheter är begränsat är en sådan lösning ofta tillräcklig. I ett fall med ett stort antal enheter måste användaren dock hålToday, an increasing amount of physical devices are obtaining Internet connectivity for more efficient management and device communication. In home environments, users may manage devices by providing them descriptive names such as "living room speaker". For a limited set of devices such a solution is often sufficient. However, in a case where one wants to individually manage a very high
Gräsrotsfinansiering är ett relativt nytt digitaliserat finansieringsalternativ, som växer snabbt både på den svenska och den globala marknaden. Gräsrotsfinansieringsplattformarna syftar till att förmedla kontakten mellan kapitalsökande bolag och investerare. Den snabba tillväxten har dock bidragit till att lagstiftningen har hamnat efter, vilket antas ha påverkat investerarna på plattformarna negCrowdfunding is a new digitized alternative to find capital, compared to other traditional financing methods. The process involves a platform that simplifies for capital seeking companies to find investors. During these past years, the growth of crowdfunding has increased significant, but the legislation hasn’t followed the process. This assumed to have a negative impact on the investors of the pl
Beräkningsmodeller för konsumtionsbaserade utsläpp, vad är vitsen? Julia Nordström i juni 2018 År 2015 skrev Sverige tillsammans med andra nationer under det internationella klimatavtalet - Parisavtalet. För att nå de mål som Parisavtalet satt upp måste de globala utsläppen av växthusgaser minska drastiskt de kommande åren. Sverige är ett av de mest framstående länderna i världen när det kommer tIn recent years, it has become increasingly recognized that the traditional production-based methods for calculations of greenhouse gas emissions have shortcomings. This is justified by the fact that such inventories only include emissions that occur within a particular geographical area. As major emissions also arise as a result of imports of goods and services and from international travel, such
Contemporary Russia is among some of the most unequal countries. After the fall of the Soviet Union, economic inequality has rapidly increased, and social discontent is rising as demonstrated by the continuous protests that culminated in opposition rallies during March 2017. Despite these events, political stability characterizes the current conditions of the Russian regime. What are the forces ma
It is well established that bumblebees play a vital role in the ecosystem, not only as pollinators but as providers of other ecosystem services. Thus, it is important to have a good understanding of their habitat requirements and ecology. Bumblebees can learn to associate floral cues with rewarding and unrewarding flowers. The availability of resources in flowers is very dynamic as it varies durin
I en undersökning från 2012 som publicerats av Statskontoret uppgavs det att Sveriges markanvisningssystem hade fått kritik för att vara för oförutsebart och det ifrågasattes om dåvarande system gynnade konkurrens och likabehandling av byggherrar. För att öka transparens och konkurrens samt för att hitta ett verktyg som kan utgöra ett bra stöd för kommunerna, infördes 1 januari 2015 lag (2014:899)This master thesis evaluates the outcome of the Law (2014:899) on guidelines for municipal land use that were adopted in 2015. According to this, all the municipalities who work with the land allocation processes, must adopt guidelines for this process. The law does not regulate in detail and it is therefore open for interpretations. The reason to adopt the law was to increase transparency, predic
Att tvångsomhänderta ett barn enligt LVU (Lag om vård av unga (1990:52) innebär en inskränkning av de enskilda fri- och rättigheterna och innebär ett av de mest långtgående ingripandena i en familjs liv, vilket följaktligen ställer höga krav på rättssäkerheten och på förutsebarheten i lagarna. Rekvisiten i LVU redogör för när beredande av vård är motiverat. Ett av dessa är att det ska föreligga The Swedish social services are the authorities that have the right to take a minor into custody without the consent of either the minor or its parents. In order to do so, thorough investigations have to show that there are deficiencies in the child’s home environment or in his or her behavior. Nor the less, there also must be a significant risk that the minor’s health and development will be
The aim of this study was to investigate how people who have been on sick leave due to fatigue syndrome, reason about the interaction with authorities, the employers and health care, and how they describe their experiences of the sick leave procedure and their way forward from there. We conducted a qualitative study with nine semi-structured interviews. For our theoretical approach we applied the
Is the management of Type 1 Diabetes best left to the medical sciences, or do the social sciences have a stake as well? In ‘Sweet Blood Surveillance,’ I push back against the perceived domination of scientific objectivity to make space for the subjective experience of diabetes in the maintenance of glucose levels through a collaboration with medical technical objects. To accomplish my task, I crea
