Variationer i normal språklig förmåga hos vuxna jämfört med neural aktivitet

Since the brain is an important prerequisite for human language there is a great interest to gain more knowledge about healthy brain activity during language mediated communication. This study examines variations in high level language ability relating to demographic factors like gender and age and relates language ability to neural activity.Eighteen individuals in ages between 22 and 64 were included and divided into groups in relation to gender and age. The material used to assess language ability was derived from Testbatteri för Bedömning av Subtila Språkstörningar (Laakso, Brunnegård, Hartelius & Ahlsén, 2000), Swedish Lexical Decision Test (Almkvist, Adveen, Henning & Tallberg, 2007) and a reading test (Högskoleprovet). The results were correlated with measured brain activity using functional Magnetic Resonance Imaging (fMRI) and language paradigms. ANOVA was applied to discover possible demographic variances in language ability as well as in brain activity.The results showed no significant differences in language ability.

Posthumanism i förhållande till digitala spel

Detta kandidatarbete undersöker hur digitala spel kan skapas med någon annans synsätt. Vi ville se vad som hände om vi försökte göra spel på ett posthumanistiskt sätt och om detta hade förändrat något. Det har uppkommit speciella möjligheter och konsekvenser under processen, det har även dykt upp frågor. En av dessa frågor är hur skapandet av varelser inom digitala spel kan utföras. Likväl har det under projektet skett diskussioner och tester runt hur ett verktyg för detta ändamål skulle kunna fungera.

Detektering av in- och utandning vil bilkörning med hjälp av Matlab

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

Upplysning enligt IAS 36 : En kvantitativ fallstudie av två branscher

Background: Goodwill has been a hot and debated topic for a longer period of time. Researchers have debated how goodwill should be accounted for and have not come to a solution. In 2005 IFRS standards came which meant that goodwill no longer will be amortized according to plan, but to be put through a yearly impairment test.Problem: A number of disclosure requirements in the financial reports have been made in an effort to avoid companies to account for goodwill differently. Apparently there still is a problem of how companies account for goodwill and there are several studies in the subject. But no one has studied how it is between two different industries, which make this study interesting to execute.Purpose/questions: This study have the purpose to investigate how the industries day to day wares and health care regards the disclosure requirements for goodwill by the impairment tests.

Multipel Skleros En kartläggning av infektionskomplikationer i samband med hematopoetisk stamcellstransplantation

ABSTRACTMultiple sclerosis (MS) is the leading cause of adult disability inSweden. Hematopoietic stem cell transplantation (HSCT) can be used as a treatment option for patients with MS where the disease has an aggressive course. The treatment is preceded by high-dose chemotherapy which lowers the patient's immune system. It is therefore of interest to study infectious complications associated with HSCT in this patient.Aim: The purpose of this study was to identify infection problems in this population associated with HSCT, and to study differences in infectious complications between this group and patients diagnosed with lymphoma who have undergone the same treatment.Method: The study was a retrospective descriptive study with quantitative data. A medical record review was conducted.

Induktiv provning av ferritiskt rostfritt stå

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

Avlastningsarmstöd till Grip-it : Optimal positionering av övre extremitet vid gripstyrkemätningar

In today?s technological society, there are increasingly less physical demands on the locomotor system. However, despite that notion strength and function in the hand?s complex biomechanical system are in fact both needed to cope with daily life. The grip function is a main function in the hand and is used in many examples of scientific research, for instance when assessing physical health and predicting the probabilities of premature mortality.

"Fettpärlan har vi så det räcker till alla!" : En jämförande studie av hur fyra lärare på de studieförberedande och yrkesförberedande programmen tänker och arbetar kring och med litteraturundervisning

On 1 January 2005, IFRS (International Financial Reporting Standards)was mandatory for all listed companies within the European Union. The introduction is to create a transparent and consistent reporting. Mainly to provide companies, investors and financiers the same access to world capital markets. Since the introduction of IFRS, the goodwill value is determined by annual impairment tests. If an impairment of goodwill is a fact the goodwill decreases in value.

Olika typer av täckning och samodling och dess påverkan på antalet skadegörare i en Pak choi odling :

The purpose of this report is to examine the possibilities to decrease the number of insects and other pathogens in a crop of pak choi (Brassica rapa), grown with different types of cover and living mulches. Included in the report is a study of literature where amongst others, a summary on the vegetable pak choi and theories of living mulches and different kind of covers are to be found. To examine the amount of predators in the field, traps were used. During the autumn 2002 the tests were conducted in Alnarp. The pak choi and the living mulches were planted/sawn at the same time, the different covers were also applied at this time. The total experiment was divided into six different treatments (plus control) of which three were with covers and three were with living mulches. Once a week the number of leaves, the height and damages were read on ten of the plants from each parcel.

"Imse vimse spindel klättrar upp igen" : En studie av åtta lärares erfarenheter av att arbeta med att utveckla elevers läsförståelse

My point of origin concerning this thesis was an interest for how school may develop students? reading comprehension. International surveys show that the results for Swedish students? performance regarding reading comprehension have declined and the current curriculum, Lgr-11, emphasizes the importance of incorporating this into all school subjects. The special teacher education programme has raised the awareness concerning the importance of including the students and that learning is achieved in an interactive setting.

Utveckling av substratmixen vid Mosseruds biogasanläggning : Substratkartläggning och rötningsförsök i laboratorieskala

The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.

Injektion till katt ? injektionsassocierad smärta samt injektioner i praktiken

Intramuscular injections to cats can generate strong reactions in some individuals while reactions of the same extent, according to the author, not always are recognized when using the subcutaneous route. The reactions are probably caused by fear, stress and/or pain. When the injection can generate pain one has to take that into account, which can be a limitation in treatment. It is well known that injections generate pain, but knowledge about the cause and processes of the injection-associated pain is limited. This is mainly due to the difficulty in finding objects to study pain on, high cost of use of laboratory animals and difficulty to obtain objective measurements. Although there is evidence that there may be a local muscle injury by intramuscular injection, it is not always that the extent of damage is related to the pain experienced. Facts about the causes of injection-associated pain have been studied in a literature review.

Jämförelse mellan ?Auditory Brainstem Response (ABR) och ?Auditory Steady State Response? (ASSR) för att uppskatta hörtrösklar på barn i narkos. Kan testtiden minska om 500 Hz utesluts vid ASSR-mätning?

ObjectiveThe objective of this study was to investigate the clinical application to use ASSR in anesthetized childrenDesignOne main ambition of the investigation was to compare hearing threshold using ABR with estimated hearing threshold using ASSR. Another aim was to examine if the duration of an ASSR measurement could be reduced by only using the frequencies 1, 2 and 4 kHz and exclude the frequency 0.5 kHz. This is a retrospective study using electrophysiological measurement from a database.ResultResults showed a high correlation between hearing threshold using ABR and estimated thresholds using ASSR, with the frequency 0.5 kHz showing a slightly lower correlation. Result also showed that the test duration was increased when using all test frequencies in ASSR-measurement compared to when 0.5kHz was excluded. ConclusionThe study showed a high correlation when comparing hearing threshold using ABR and ASSR.

Synergonomi och arbetsbelysning för sjuksköterskor inom avancerad hemsjukvård

The main aim of this master thesis was to examine the visual ergonomics and the systematic work environment management concerning lighting issues for nurses within domiciliary care. Further aims were to examine a few existing lighting solutions, to come up with ideas for future possible lighting solutions, and to evaluate if the legal regulations for lighting is satisfying and if the regulations are obeyed in domiciliary nursing.The methods used were a questionnaire completed by 55 nurses, field studies of used lightings in cooperation with a student in industrial esign, test of ten existing lighting solutions in a laboratory environment, and a field test of five existing lighting solutions tested by nine nurses in the home of the patient.The result indicates that 40 % of the asked nurses were dissatisfied with the working light in the patient?s homes. All respondents reported poor working light close to the patient, 50 % reported that this problem occurred daily. One third reported that they had to work in uncomfortable working postures due to insufficient working light, and 15 % reported risk of making mistakes due to the same reason.
