GaxIn(1−x)P nanowires with suitable bandgap (1.35-2.26 eV) ranging from the visible to near-infrared wavelength have great potential in optoelectronic applications. Due to the large surface-to-volume ratio of nanowires, the surface states become a pronounced factor affecting device performance. In this work, we performed a systematic study of GaxIn(1−x)P nanowires' surface passivation, utilizing A
This ethnographic research on ‘Workaway’ investigates new forms of mobility experiences, in between travel and migration, which are used by a plethora of types of people (both hosts and guests) with different motivations (learning new skills and experiences), needs, ambitions, dreams, as well as/or life-time crisis, and different types of problems (e.g. lack of finances, no opportunity or prospect
Endoscopy is not a modern invention but the history of endoscopy goes back to ancient times in Egypt and Greece when speculums were used to inspect the nose cavity, vagina and anorectum. The modern era of endoscopy started in the 19th century with the development of straight metallic tubes with primitive light sources, such as Bozzini´s »lichtleiter« and Desormeaux´s »endoscope«. The first gastros
The extensive discussions of the relationship between the history of science and the philosophy of science in the mid-20th century provide a long history of grappling with the relevance of empirical research on the practices of science to the philosophical analysis of science. Further, those discussions also touched upon the issue of importing empirical methods into the philosophy of science throu
This study presents a 2-yr follow-up of 281 patients, aged 15-34 yr, diagnosed with diabetes between 1992 and 1993. At diagnosis, 224 (80%) patients were positive for at least one of the following autoantibodies: islet cell antibodies (ICAs), glutamic acid decarboxylase antibodies (GADAs), or tyrosine phosphatase antibodies (IA-2As); the remaining 57 (20%) patients were negative for all three auto
A tandem solar cell consisting of a III-V nanowire subcell on top of a planar Si subcell is a promising candidate for next generation photovoltaics due to the potential for high efficiency. However, for success with such applications, the geometry of the system must be optimized for absorption of sunlight. Here, we consider this absorption through optics modeling. Similarly, as for a bulk dual-jun
Background: The knowledge about air pollution effects on birth weight, prematurity and small for gestational age [SGA] in low-exposure areas is insufficient. Objectives: The aim of this birth cohort study was to investigate if low-level exposure to air pollution was associated with prematurity and foetal growth and if there are gender specific effects. Method: We combined high quality registry inf
Numerical schemes and stability criteria are developed for solution of the one-dimensional fractional advection-dispersion equation (FRADE) derived by revising Fick's first law. Employing 74 sets of dye test data measured on natural streams, it is found that the fractional order F of the partial differential operator acting on the dispersion term varies around the most frequently occurring value o
One of the more puzzling aspects of Kant’s political thought is his insistence on the duty to obey even oppressive rulers combined with his belief in the republic as the only rightful constitutional form. In arguing that resisting oppressive power is as wrong as seizing it, Kant seems committed to the awkward position of denouncing as unrightful any attempts made by the people to establish the onl
Cancer patients diagnosed with type 2 diabetes mellitus (T2DM) are at an increased risk of death due to cancer. However, whether T2DM comorbidity increases other causes of death in cancer patients is the novel theme of this study. Patients with T2DM were identified from the nationwide Swedish Hospital Discharge Register and linked with patients with cancer recorded from the Swedish Cancer Registry
ABSTRACT: BACKGROUND: It is well known that physicians' night-call duty may cause impaired performance and adverse effects on subjective health, but there is limited knowledge about effects on sleep duration and recovery time. In recent years occupational stress and impaired well-being among anaesthesiologists have been frequently reported for in the scientific literature. Given their main focus o
Kontinuitetsprincipen och fångesklassificering har ofta ett direkt samband. Att en överlåtelse klassificeras som gåva medför i regel att inkomstbeskattning kan underlåtas när en tillgång överlåts och att mottagaren övertar obeskattat värde i enlighet med kontinuitetsprincipen. Vid underprisöverlåtelser enligt reglerna i 23 kap. IL finns visserligen en lagstadgad kontinuitetsbestämmelse som är till
The aim of this study was to examine what the preventative operation Family mobilization, that involves both social service and school, contributes with for the families and the pedagogues that are involved. This regarding similarities and differences between the intentions and the realization of the operation, together with the cooperation between the home and the school focusing on participation
Stora mängder miljögifter har läckt ut i Braån i snart 50 års tid – men hur dåligt mår ån, egentligen? År 1975 uppdagades vad som kom att kallas Sveriges största miljöskandal i Teckomatorp, Skåne. Upp till tusen tunnor innehållande miljögifter hade grävts ner i marken på den växtgiftsproducerande fabriken BT Kemi:s fabriksområde, något som resulterat i extrema föroreningshalter i mark och läckageAs things stand there are almost 24,500 risk classified contaminated sites in Sweden. One of the most well-known is the BT Kemi area in Scania. BT Kemi was an herbicide producing factory that in the 1970s buried a total of 1000 barrels containing toxic waste on their factory grounds. A few years later the toxins started to leach into soil and water. Today, 50 years later, the area is still pollute
Syfte: Studiens ändamål är att utreda de externa värderarnas syfte för användarna av fastighetsbolagens finansiella rapporter. Vi ämnar även undersöka till vilken grad de externa värderarna är oberoende i sina värderingar och analysera den informationsasymmetri som råder i branschen. Metod: Uppsatsen är en kvalitativ intervjustudie av explorativ karaktär och ämnar undersöka externa värderares syfPurpose: The study's purpose is to investigate the external appraisers purpose for the users of real estate companies' financial statements. We also intend to investigate to what extent the external appraisers are independent in their valuations and analyze the information asymmetry that exists in the industry. Methodology: The thesis is a qualitative interview study of a comparative natu
As a result of the official report on democracy (Demokratiutredningen), the Swedish government decided in 2002 to prescribe by law the right of initiation for common citizens in city councils (medborgerlig förslagsrätt). All citizens are therefore now entitled to submit a proposal which then will be dealt with by the city council as a motion. In this paper the handling of the citizen proposal is s
Models for dynamic simulation of a parabolic trough concentrating solar power plant were developed in Modelica for the simulation software Dymola. The parabolic trough power plant has a two-‐tank indirect thermal storage with solar salt for the ability to dispatch electric power later in the evening and during the night when little or no solar irradiation is present. The complete system consists
Arbetstagare som presterar upphovsrättsliga verk inom ramen för en anställning omfattas av två huvudsakliga regelverk: det arbetsrättsliga och det immaterialrättsliga. Inget av regelverken innehåller uttryckliga bestämmelser för sådana verk som uppkommer under en anställning, med undantag för bestämmelsen i 40 a § URL avseende datorprogram.

This thesis examines the effects of a low real interest rate environment on household savings. It specifically analyses whether there can be an increased importance of the income effect relative to the intertemporal consumption substitution effect and whether there can be an increased potency in the wealth effect of the stock market due to the financial assets substitution effect in this environme
