Genom att utvärdera Skochparametern och skapa tre konceptkompressorer har examensarbetet försökt komma till en slutsats om hur bladens längdförhållande påverkar en kompressors verkningsgrad och stabilitet. Skochparametern visade sig fungera mindre bra som ett verktyg och det visade sig att ett lägre längdförhållande innebar en liten minsking i verkningsgrad, men en betydande ökning i stabilitet. The design of an axial compressor is mainly the trade-off between efficiency, stability and cost. A parameter that affects all of these three aspects is the blade aspect ratio. Due to the intricacy and complexity of the flow in a compressor, solely the effect of the blade aspect ratio variation is difficult to obtain. A parameter that supposedly is a gauge of the combined airfoil and end wall loa

This study has examined the relationship between the increase in consumption of white snus among Generation Z in Sweden and the branding strategies used by the nicotine brand LYFT. The purpose of this research has been to gain an understanding of how a brand can market a regulated product to a young consumer segment by conducting strategic communication prefered by these young individuals. The bac

The energy sector in the world today is in the middle of a huge challenge regarding grid development and power production. Whilst a significant part of the world's population are struggling without access to electricity, the more developed part of the world is trying to replace existing energy sources into renewable ones, and are also facing the challenge of an aging grid which is in desperate

In this paper I have investigated the construction of the professional social worker in Swedish journals and newspapers. My empiric material is a collection of major articles published in Sweden between 2002 and 2012. The thirteen articles analyzed in this paper is a selection from 1250 relevant articles found between these years. When analyzing the empirical material I have been working with a di

Detta arbete handlar om en behandlingsteknik för hudterapi där lågenergetiska elektroner utnyttjas för strålbehandling där patienten står eller sitter på en roterande plattform. För att behandlingen skall få ett lyckat resultat krävs en viss stråldos (den absorberade energin per massenhet) till patientens hud. För att kontrollera att dosen är rätt används normalt mätningar med olika detektorer. DeBackground and purpose: This study refers to a rotational radiotherapy technique for the treatment of mycosis fungoides. Patients are irradiated by a high dose-rate low-energy electron beam while they stand on a rotating platform. This report presents a first effort to use the Geant4 simulation program to calculate the relation between the stationary and rotational depth dose distributions in an e

Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter. Plotting these stars as [C/O] vs [O/H], it is revealed

Formulating and implementing agricultural policies are important for the development of the agricultural sector and the rural population. The process of policy making is a political bargain between politicians and citizens. The outcome of this process, the policies, cannot be expected to be Pareto efficient resource allocations since altruistic behaviour is not very likely. All participants in the

What are the social positions of adults who were in long-term foster care as children, compared with the general population and with adults who grew up at home in families similar to foster children's birth families? How common is it to have been in foster care? Four approaches are used in this study: - A systematic review of around 50 studies on adult foster children. Conclusions are more pessim

Context: Scope management is a core part of software release management and often a key factor in releasing successful software products to the market. In a market-driven case, when only a few requirements are known a priori, the risk of overscoping may increase. Objective: This paper reports on findings from a case study aimed at understanding overscoping in large-scale, market-driven software dev

Popular Abstract in Swedish Många forskningsprojekt inom materialvetenskap, medicin eller grundläggande fysik kräver smala strålar av laddade partiklar som fungerar som provtagare för att undersöka materiens egenskaper. Dessa partiklar kan vara protoner, elektroner lättare joner. Relativt ofta, behöver de accelereras nästan upp till ljusets hastighet för att kunna tränga in tillräckligt djupt i prLaser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the

Objectives To determine which endometrial morphology characteristics as assessed by gray-scale ultrasound and which endometrial vessel characteristics as assessed by power Doppler ultrasound are useful for discriminating between benign and malignant endometrium in women with postmenopausal bleeding (PMB) and sonographic endometrial thickness > 4.5 mm and to develop logistic regression models to ca

While preterm contractions occur almost as often extremely preterm as they do closer to term, birth due to spontaneous preterm labour before 27 weeks of gestation is rare, accounting for 0.05–0.7% of all births in different populations. Although the likelihood that uterine contractions before 27 weeks of gestation represent true preterm labour is low, the risk of adverse outcome in such cases is h

Background: It is well known that women suffer from negative consequences following breast cancer (BC) treatment and that their largely varying needs for rehabilitation are often unmet. Up to 43% of these women are at risk of developing chronic distress requiring complex interventions; however, how to early identify and meet these women's needs is unknown, leaving them with suboptimal chances of r
