Sjuksköterskeyrket är ett mångfacetterat arbete som kräver och stimulerar till livslångt lärande. Vården som bedrivs idag är i ständig, pågående förändring med nya behandlingar, högteknologiska tekniker och ett arbete i komplexa vårdmiljöer. Ett kontinuerligt lärande är väsentligt för att upprätthålla kompetensen. Syftet med litteraturstudien var att belysa faktorer som påverkar sjuksköterskans lä

Functional food (FF) is a relatively new sector in the food industry. FF are products that have an added nutritional value for consumers that is communicated through nutritional and health claims, and act as preventive agents of chronic diseases. Innovation of new FF products has grown to become an important impact in research towards preventing welfare diseases. The rate of innovation in this fie

I denna studie undersöker jag hur några studerande inom miljövetenskap, hanterar den problematik som råder mellan att försöka vara miljövänlig och upplevelser av de krav och begränsningar som innebär att leva i ett konsumtionsinriktat samhälle. Intresset ligger i att skapa en förståelse för hur denna problematik uppfattas av intervjupersonerna på en individnivå. Med hjälp av intervjuer undersöks d

The Vision Zero was initiated in 1997 with the aim that no loss of life or seriously injured are acceptable in the transportation system. To improve the traffic safety the National road administration in Sweden, Trafikverket, has defined two areas with considerable potential to change the traffic safety situation and reduce number of people killed in traffic. These are lower “average speed” and hi

With estuarine bacterioplankton as a key player in the nutrient cycle and the amount of DOC transported to sea increasing, it is important to gain a better understanding of how the processes within the catchment and estuary control the degradation of DOC by bacterial communities. Future climate change scenarios add a new dimension to this question, with predicted precipitation increases translatin

Background For a long time, Axis has mainly focused on network cameras. But lately Axis is turning its focus towards a different kind of approach, looking more at the customers and their needs, which has given end-to-end solutions and customer segments increased attention in different departments within Axis. A sustainable portion of Axis’ offering is its accessories, but this branch of products h

Bakgrund: Den industriella eran har kommit till sitt slut och med en ny epok kommer nya förändringar. Nya generationer växer upp i en allt mer digitaliserad värld och deras digitala kunskap, tillförlitlighet och sätt att leva påverkar hur vi kommer att arbeta och leva i framtiden. Digitalisering håller på att skriva om spelreglerna för hela branscher och organisationer. Företag med ledare som välj

Felaktiga mätresultat vid användning av pulsoximeter under patientövervakning En felaktig diagnos är ju inget kul att få av sin läkare. I sjukhusmiljö samt kliniska omgivningar eller under akuttransport kan pulsoximetern, som bland annat mäter syremättnaden i blodet via fingret, ge felaktiga mätresultat på grund av frivilliga eller ofrivilliga rörelser hos patienten. Under de senaste åren har bioThe aim of this thesis was to investigate methods for artifact removal in PPG signals and to implement and evaluate a few existing algorithms claiming that the amplitude information is recovered when removing motion artifacts from photoplethysmographic signals (PPG) captured from pulse oximeters. We developed a new proposed method that uses a two-stage based approach with singular value decomposit

This paper seeks to develop an understanding of how configurations of masculinity were shaped and represented by the Swedish Ballet in the 1920s through the use of a symbolic language of signs. With in-depth analysis of storylines, roles and scenography I aim to show how certain symbols, signs and metaphors where tied together to display masculinity. Further, by applying theory on space/place, thi

Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e., the Kronecker model and the Weichselberger model, and a cluster-based m

In this thesis two methods are investigated to solve a multi-objective optimization problem for voyage planning. The first method, grid search, is a brute force search in a three-dimensional graph while the other uses the Lipschitzian algorithm DIRECT to do a continuous search along a nominal route. The grid search method gives a computation time of 7.6 minutes for a route from Gothenburg to New

How tight junctions are affected in a Multiple Sclerosis model In Multiple Sclerosis (MS), unusual immune cells of unknown origin, which are supposed to protect us from infections, attack the central nervous system (CNS). Their main target is the myelin shield surrounding neuronal axons, which is essential for proper transmission of neuronal signals. These autoreactive cells can enter the CNS thr

Models of physical systems are often expressed as a system of mathematical expressions derived from first principles. However some of the relationships present in a model are more conveniently expressed as a table, i.e. for certain values of independent variables the values of dependent variables are known. This imposes a limitation on the optimization software to be used, since optimization softw

We describe the Fourier-Gauss-Laguerre and Fourier cosine series method and test them extensively in four models: Black- Scholes, Black-Scholes with discrete dividends, Heston and Bates. While both methods mostly achieve good accuracy and high computational speed, problems may arise with respect to the optimal choice of the method-specific parameters and the extension of the methods to other model

This essay is about digital addiction as a relevant mass media discourse in today’s information society. The purpose of the essay is to study this alleged digital addiction to see if it is reasonable, and then analyse how it can affect people’s relationships with technology and each other. The essay also strives to highlight the different opinions depending on generation and the discussion of digi

This master thesis is part of the development of a new industrial machine. The machine is a fully automated transplanting machine for the forest industry and will be used by nurseries around the world. Nurseries grow seedlings and sell them when they have grown enough to be planted in the ground. The machine being developed moves plants from a tray with small cells to a tray with bigger cells. Thi

Equal capacity in the activities of a production line is of great importance when a good material flow is desired. This is one of the basic ideas of the Lean philosophy, a mindset every modern company strives to follow. In a production with unequal capacity, the company might have to build up inventory to be able to meet the costumer demand. Inventory is a recognized waste in a production and a co

This thesis explores the experience of being young, Egyptian, supportive of the 2011 revolution, and active in civil society in the post-revolutionary period in Cairo and Alexandria. It draws from 5 in-depth interviews, and aims to understand the reasons behind youth’s engagement in the revolution beyond the framework of youth economic exclusion. It looks into their expectations from the revolutio

This thesis investigates word order patterns in spoken Basque for two dialects, Navarrese-Lapurdian and Gipuzkoan. The data for the analysis was elicited with stimuli pictures in an experiment in dialogue form. The 26 participants were from Hazparne (Lapurdi), Donostia, and Andoain (both Gipuzkoa). The data consists of transitive main clauses, both questions and declaratives with nominal subject a
