Nonlinear optical response of Au metallic nanoparticles, synthesized and embedded in sapphire by using ion implantation, as a function of their size and shape is studied. The size of the Au NPs was varied by controlling the annealing time of the gold-irradiated sapphire in a reducing atmosphere. Their shape was changed from approximately spherical to prolate by swift heavy-ion irradiation using Si
Portugal's real income per head grew by a factor of eight during the second half of the twentieth century, a period of fast convergence towards Western European living standards. We use a new sample of about 3,400 infants and children living in Lisbon to document trends in the prevalence of stunting and wasting between 1906 and 1994. We find that stunting and wasting fell quickly from around 1950,
We systematically fabricate devices and analyse data for vertical InAs/(In)GaAsSb nanowire Tunnel Field-Effect Transistors, to study the influence of source dopant position and level on their device performance. The results show that delaying the introduction of dopants further in the GaAsSb source segments improved the transistor metrics (subthreshold swing and the ON-current performance), due to
Of concern is the fractional Kadomtsev–Petviashvili (fKP) equation and its lump solution. As in the classical Kadomtsev–Petviashvili equation, the fKP equation comes in two versions: fKP-I (strong surface tension case) and fKP-II (weak surface tension case). We prove the existence of nontrivial lump solutions for the fKP-I equation in the energy subcritical case α>45 by means of variational method
The present study explores the value and role of the physical space of the public library from the perspective of the visitors in the context of digitalization. The qualitative research was based on semi-structured interviews with regular visitors of Idé A Drottninghög (Helsingborg, Sweden), Idé A library staff members, and collaborative organizations of Idé A that make use of the library’s physic
Spel om pengar utgör en riskfylld del av dagens samhällshandel. Överdrivet spelande och de negativa konsekvenserna av spelande ämnas motverkas genom spelansvarsåtgärderna i spellagen (2018:1138). En av dessa ansvarsåtgärder är kreditförbudet, 14 kap. 8 § spellagen, som förbjuder licenshavare och spelombud från att själva erbjuda eller lämna kredit för spelinsatser. Regeringen har nyligen i prop. 2Gambling constitutes a risky aspect of today’s modern economy. Excessive gambling and the negative consequences of gambling are indented to be countered through the gambling responsibility measures in the Swedish Gambling Act (2018:1138). One of the responsibility measures is the credit ban, Chapter 14 Section 8 of the Gambling Act, which prohibits license holders and gambling agents from offering
This report evaluates a newly made investment in FIB, First Response Crew manager in Medelpad´s Rescue service Association (MRF). The focus is to by interviews and statistics present a picture of the current situation of how well FIB is working. The results of the interviews were categorized into different themes from which the results were later discussed together with the results from the statis
En betydande andel av Sveriges företag utgörs idag av fåmansföretag, vilka spelar en avgörande roll för den svenska samhällsekonomin. Det är av stort värde att skapa goda förutsättningar för ägarskiften i befintliga fåmansföretag som möjliggör att upparbetade värden i företag med tillväxtpotential tillvaratas. Fåmansföretag omfattas idag av ett särskilt fördelningssystem, de s.k. 3:12 – reglerna. A significant proportion of Sweden's business currently consists of small companies with few employees, but these companies play a critical role in the Swedish economy. It is crucial to create good conditions for the transfer of ownership within existing private businesses and safeguard growth potential. These close companies are subject to a special regulation, the so called 3:12- rules. The
As the climate warms, the timing of plant phenology around the world is changing in response. Herbarium records offer a wealth of data that can be used to analyze phenological trends over time. While much research has been done on early spring flowering species, there is still a dearth of knowledge of climate change effects on summer and autumn flowering species. This study uses herbarium data to
Studiens fokus är på skogsbränderna i Sverige år 2018, då tio gånger mer markyta påverkades av bränder än genomsnittet under föregående år. Syftet med studien är att undersöka en bred forskningsfråga: har vägar en påverkan på storleken hos den brända ytan i en löpeld? Studien bygger på tidigare forskning om hur spridningen av löpeld påverkas av vägar. Bland olika statistiska metoder valdes slutligThis study focuses on the Swedish wildfire season of 2018, when the country incurred ten times more than the average burnt area that occurred in previous years. The study aims to address a broad research question: Do roads influence the size of the burned area? This study fills the gap in research on the effects of roads in the spatial patterns of wildfires. Moreover, the research hopes to include
Vi rör oss ständigt i offentliga rum som på olika sätt är utformade för att påverka oss. Denna studie undersöker om människors känslor, syn på välbefinnande och syn på meningen med livet påverkas av att befinna sig i olika rum, i detta fall en kyrka (N=51) och ett köpcenter (N=51). Två verktyg, semantiska mått och Positive and Negative Affect Schedule (PANAS) används för att undersöka om det finnsWe are constantly moving between environments that are designed to affect us in one way or another. The purpose of this study is to investigate if the room has an influence on people's feelings, and their views on well-being and meaning of life. In a randomised experiment, the study explores whether there is a measurable difference in the participants’ feelings and thoughts in a church (n=51)
Plattektoniska processer formar idag vår jord genom vulkanism, relaterad till divergenta och konvergenta plattrörelser. Hur länge har plattektoniken existerat och hur kan vi spåra plattektoniska processer bakåt i tiden? Detta kandidatarbete behandlar och diskuterar olika typer av plattektoniska indikatorer, hur de går att koppla till moderna processer och hur tillförlitliga de anses vara. Moderna Plate tectonic processes shapes our earth due to volcanism, related to divergent and convergent plate motions. When did plate tectonics begin and how can we trace plate tectonic processes throughout time? This Bachelor thesis address and discuss different plate tectonic indicators and their reliability. Modern analogues are indicators that can be linked to modern plate tectonic processes, and does
According to traditional trade theory, trade reduces inequality between the rich and the poor. However, since the beginning of the 1980s, a constantly rise in within-country inequality has been observed in many developed and developing countries. With the rapidly increasing globalization during the same period in mind, a natural question to ask is whether the two phenomenon are linked. In this pap
The European Corn Borer (ECB) has the potential to markedly reduce the yield from corn plants and in turn affect the economy of farmers. The human world population is increasing and there is consequently an increased number of mouths to feed on a limited area, the Earth, and this makes this an important topic to study. It is thus important to find out whether the ECB likely will be an important pe
With the continuous increase of rapid urbanization and population growth, sustainable urban land-use planning is becoming a more complex and challenging task for urban planners and decision-makers. Multi-objective land-use allocation can be regarded as a complex spatial optimization problem that aims to achieve the possible trade-offs among multiple and conflicting objectives. This paper proposes
