Highly-Educated Immigrants in Sweden

Purpose: The purpose of this thesis is to provide the reader with insights regarding what Syrian highly-educated immigrants (HEI) in Sweden think are the underlying prerequisites and actions needed to facilitate their entrance into the Swedish job market. Key Research Question: What are the key requirements needed to expedite the employment of HEI in the Swedish job market, and take up relevant jo

Cloning, Purification and Characterization of Ribonucleotide Reductases from Pseudomonas aeruginosa and Chlamydia trachomatis

Ribonukleotidreduktaser (RNR) är livsviktiga enzymer som är involverade i nästan alla levande organismer. Enzymernas uppgift är att omvandla ribonukleotider (NTPer) till deoxyribonukleotider (dNTPer), byggstenar som är essentiella för såväl DNA-syntes som DNA-reparation. Enzymernas aktivitet baseras på en radikal-mekanism som skiljer sig, vilket gör att RNRerna är uppdelade i tre olika klasser. UtRibonucleotide reductases (RNRs) are important enzymes that convert the building blocks of RNA (NTPs) into building blocks of DNA (dNTPs). dNTPs are used for synthesis of DNA as well as repair of mutated and damaged DNA. These cellular processes are critical to an organism. That is why these processes are found in various organisms. Since these processes are so essential, their allosteric regulati

Survival of patients with kyphoscoliosis receiving mechanical ventilation or oxygen at home

Background: Home mechanical ventilation (HMV) and long-term oxygen therapy (LTOT) are the two treatment alternatives when treating respiratory insufficiency in patients with kyphoscoliosis. We aimed to study the effect on survival with regard to HMV or LTOT alone in patients with respiratory insufficiency due to kyphoscoliosis. Methods: Swedish patients with nonparalytic kyphoscoliosis (ie, scolio

What a hawkmoth remembers after hibernation depends on innate preferences and conditioning situation

Nectar-feeding insects find flowers by 2 means, innate preferences and learned associations. When insects that hibernate as imagos (i.e., adults) start foraging after a long winter break, what guides them to new nectar rewards? Are innate preferences kept over such a long period? And are learned associations useful after long breaks? In a series of experiments I show here that, depending on previo

Waiting management at the emergency department - a grounded theory study

Background: An emergency department (ED) should offer timely care for acutely ill or injured persons that require the attention of specialized nurses and physicians. This study was aimed at exploring what is actually going on at an ED. Methods: Qualitative data was collected 2009 to 2011 at one Swedish ED (ED1) with 53.000 yearly visits serving a population of 251.000. Constant comparative analysi

Chimpanzee (Pan troglodytes) and orangutan (Pongo abelii) forethought: self-control and pre-experience in the face of future tool use.

Planning for future needs has traditionally been considered to be restricted to human cognition. Although recent studies on great ape and corvid cognition challenge this belief, the phylogenesis of human planning remains largely unknown. The complex skill for future planning has not yet been satisfactorily established in any other extant primate species than our own. In humans, planning for future

Energy efficiency in residences - Challenges for women and men in the North

In a Northern country such as Sweden, energy use in the home may be reduced by 20% through changes in behaviour. However, little is known about how households respond to policy instruments encouraging such change or to what degree this in turn may affect the workload of women and men in such communities. The current study presents findings from interviews with 30 households in Sweden that particip

Socialsekreteraren genom andras ögon - poliser, lärare och psykologer om socialtjänsten

The aim of this study was to examine how social workers are described by actors of other professions’ who regularly cooperate with social workers. Social work with children is an area that involves several professions. The questions we intended to look at were: How do these actors describe and view the social worker and his or her work? How do other professions look at their collaborations with so

Autonomy and International Law in the Context of the Nisga'a Final Agreement

The Nisga'a Final Agreement (NFA) is a legal agreement between the Nisga'a Nation of the Nass Valley, the government of British Columbia and the Canadian government. For the Nisga'a it is the culmination of over a 100 years of efforts to arrive at a mutually agreeable legal framework of land ownership, resource management and self-government. This paper evaluates the Nisga'a Final

Investerarskydd vid venture capital-investeringar

This essay is devoted to quite a special form of investment - venture capital. More precisely the purpose is to map out, describe and analyse the most fundamental parts of investment protection in connection with venture capital investments. Venture capital is part of the market of risk capital, which refers to investments occuring on the receipt of, or possibility to receive ownership in a compan

Endometriomas: their ultrasound characteristics

Objectives To describe the ultrasound characteristics of endometriomas in pre- and postmenopausal patients and to develop rules that characterize endometriomas. Methods All patients included in the International Ovarian Tumor Analysis (IOTA) studies were used in our analysis. Patients with an adnexal mass were scanned by experienced sonologists using a standardized research protocol. The gold stan

Between love and fear - determinants of sexual behavior among Ugandan university students

Background: More than half of all new HIV infections in sub-Saharan African countries, including Uganda, occur among young people between the ages of 15 and 24, the most sexually active period of their lives. Understanding the contextual determinants of sexual behavior in this group is crucial in combating the pandemic. Aim: The overall aim of this study was to assess the impact of demographic, r

Who decides the position for birth? A follow-up study of a randomised controlled trial

Background: Physical benefits are suggested for women and their babies when women adopt an upright position of their choice at birth. Available care options during labour influence women's impressions of what intrapartum care is. This indicates that choice of birth positions may be determined more by midwives than by women's preferences. Question: The aims of this study were to investigate factors

Driver Experience and Acceptance of Driver Support Systems - A Case of Speed Adaptation

Substantial research and development efforts are being made to add driver support systems to the arsenal of traffic safety measures. Obviously, the system cannot reduce fatalities and trauma until it is actually used. Hence, drivers’ experiences and acceptance of the system are of paramount importance. A driver support system (ISA) has been investigated by means of real life trials in Sweden, Hung

On improving NLO merging for t t ¯ W production

We introduce an improvement to the FxFx matrix element merging procedure for pp →tt¯ W production at NLO in QCD with one and/or two additional jets. The main modification is an improved treatment of jets that are not logarithmically enhanced in the low transverse-momentum regime. We provide predictions for the inclusive cross section and the tt¯ W differential distributions including parton-shower

Formation of nanogaps in InAs nanowires by selectively etching embedded InP segments

We present a method to fabricate nanometer scale gaps within InAs nanowires by selectively etching InAs/InP heterostructure nanowires. We used vapor-liquid-solid grown InAs nanowires with embedded InP segments of 10-60 nm length and developed an etching recipe to selectively remove the InP segment. A photo-assisted wet etching process in a mixture of acetic acid and hydrobromic acid gave high sele

In the wake of a bird - Quantifying aerodynamic performance of avian flight

Flight is an expensive form of locomotion, but also offers the ability to travel great distances at relatively low cost. Birds have developed various adaptations for optimizing flight performance. The main aim of this thesis is to identify how morphological variables in birds affect aerodynamic drag and flight performance. To this end I studied the aerodynamic performance of a jackdaw (Corvus mone
