Hur pusslar man ihop ett liv som gått i tusen bitar? : En litteraturstudie om föräldrars upplevelser av att ha ett barn som drabbats av cancer
Bakgrund: Cancer drabbar cirka 250-300 barn varje år. Föräldrar har fått en alltmer betydelsefull roll i omvårdnaden av sitt barn på sjukhus. Enligt tidigare forskning har föräldrars upplevelser av vården varit beroende av sjuksköterskors bemötande, deras intresse för barnet och tillgänglighet. Familjefokuserad omvårdnad inriktar sig på hela familjen och deras behov. Syfte: Att belysa föräldrars upplevelser av att ha ett barn som drabbats av cancer.
Skolsköterskors användning av MI-metoden
AbstractMI stands for Motivational Interviewing, the Swedish translation of MI is Motiverande Samtal. Adolescence is a period in life when challenges are encountered and pivotal choices are being made. It is during this period adolescents form their lifestyle, which have an impact for their health for the rest of their life. MI has shown to be an effective and appropriate method for school nurses within school health care, to utilize in approaching by adolescents with risk behavior. This is because it gives adolescence to take responsibility and empowers them to make decisions regarding lifestyle-changes.

Metodik för utmattningsberäkning av svets i vibrationsmiljö
In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.
Statusbedömning av asynkronmotorer
Induction motors, often referred to as the workhorse of the industry, play an important role in production today. Therefore, it's important to diagnose any faulty induction motor prior to failure to avoid costly and time consuming production stops.This thesis compares methods for diagnosing induction motors in operation, MCSA, Park's vector approach and the standard method used by Swedish industries today. By simulating broken rotor bars and short-circuit in one of the windings, each method is tested and the results are compared using matlab.The results need further verification due to uncertainties of the condition of the test motor, even though the experiment gives a hint of the different advantages of each method. A combination of the methods should be able to tell if the motor needs further examination..
Reflekterande eller reproducerande matematik : en jämförande studie mellan två undervisningsmetoder i matematik, det laborativa och det traditionella
In each classroom there is a teacher with good intentions wanting what´s best for their pupils. But grades and tests in mathematics from 2009 in Sweden shows there is a crack between the subject being taught and the learning child. The purpose with this research is to find an understanding from a teaching and learning perspective of which teaching method is more suitable for teaching and learning mathematics by doing a comparison between two methods. The main question is:What are the advantages and disadvantages of the traditional and the laboratory method of teaching, supported by the two keywords teaching method and learning?This C-paper is based on a qualitative research aiming to gather an in-depth understanding of human behavior.
Jämförelse mellan MultiScat och konventionell beräkning av intensiteter till koncentrationer vid analys med röntgenflourescensspektrometri
In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.
?Women will never fight in the UFC? : En kvalitativ inneha?llsanalys av kvinnlig MMA?s framsta?llning i media
?Never!? That was the answer UFC President Dana White gave when asked when women would be seen in the UFC. Two years later the first fight between two women took place and now there?s more than 50 female competitors in the UFC - an organisation that earlier was reserved only for men.?Women will never fight in the UFC? ? A qualitative content analysis of the depiction of women?s MMA in media is a study which focuses on how women?s MMA and Ronda Rousey as an individual athlete are portrayed in american internet based MMA media, with a gender research perspective. This study also investigates how the introduction of the first women?s division in the UFC might have affected the depiction women?s MMA in media.The theoretical framework consists of gender theory concepts such as gender performativity, the man as norm, sports and masculinity.
Löpmagsförskjutning hos mjölkkor : en besättningsutredning för att identifiera riskfaktorer för metaboliska störningar
The purpose of this study was to find possible explanations to why the studied herd had an increased incidence of abomasal displacements. The incidence of abomasal displacement in the herd was three times higher than the incidence of an average Swedish herd. The cows in this study were fed a total mixed ration. The different parameters studied were: energy content in food, nutritional content in food, body condition scoring, concomitant other diseases, and blood parameters of glucose, fructosamine, cholesterol, insulin, betahydroxybutyrat and free fatty acids. The author?s suggestions to decrease the problems are to decrease the energy content in the TMR to lower the cows? body condition scores in the dry period and changing the content in the TMR to increase the amount of NDF and adding structure in the form of chopped straw.

A comparison of methods to assess site index in young Norway spruce stands
This study investigates whether the site index curve method (SICM) and the growth intercept method (GIM) can be used for site index predictions in younger Norway spruce (Picea abies (L.) Karst.) stands than recommended by current guidelines. For SICM it was thus investigated whether the method could be used for stands younger than ten years, and for GIM it was tested whether a starting point for the intercept measurements could be used below the recommended
2.5 meter. This was tested based on measurements taken from experimental stands in Tönnersjöheden Research Forest.
For GIM it was found that the method can only be used when the TH-trees of a stand have five complete intercepts above 2.5 meters. For the method to be applicable beyond this, it will be necessary to adapt the underlying equations, perhaps following the Canadian example where a 1.3 meter intercept start is used. In conclusion it is not currently possible to apply the approach beyond the current recommendations.
For SICM, SI predictions are accurate for the study area already form year three.
Evaluation of a selective media for the detection of gram-positive bacteria in leg ulcers and pressure wounds
Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens. The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.
Estimering av GPS pålitlighet och GPS/INS fusion
The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning. An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.
Utveckling av metoder att mäta centrering av skruvhål i skär
There have been, in some rare cases, difficulties with clamping of inserts with U-holesin their tool holder. According to the complaints, the inserts could not be properlyclamped or could fracture when clamped. A study has shown that variations inclamping behaviour are mainly depending by the position of the screw hole in the toolholder and the centering of the screw hole in the insert.The focus of this project has been the centering of screw hole in insert. It has beenshown that the screw holes are not always enough centered in the insert. Theproblem may occur after a certain step in the production, i.e.
