The Yara N-Tester is a handheld chlorophyll meter which can be used in several different crops as an aid to determine if there is a need of complementary fertilization with nitrogen (N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha. The possibility to assess the need of N depends on the strong relation that exists between chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series ?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters ability to estimate the need of N in winter wheat, will be presented for the years 2008-2011.

Shivering är ett fenomen som uppstår hos patienterna postoperativt. Det innebär att patienten har okontrollerbara muskelskälvningar som gör att patienten darrar, skälver eller huttrar i mer än 15 sekunder. Shivering påverkar kroppen negativt, men är också obehagligt och ett onödigt lidande för patienten. I takt med den tekniska utvecklingen utarbetas nya operationstekniker och idag utförs flera operationer med laparoskopisk teknik. Pilotstudiens syfte var att undersöka före-komsten av postoperativ shivering hos patienter som opererats med laparoskopisk teknik.

Abstrakt All around the world there are a lots of people that suffers from chronic pain. One great factor for the devolopment of chronic pain is the phenomen fear-avoidance/kinesophobia that appear to have negative effects on rehabilitation of chronic painproblems. The aim of the present study was to describe and identify how patient that took part in a rehabilitationprogram in year 2004 and 2005 with focus on behaviourchanges estimate their fear-avoidance/kinesophobia and examine if there was any changes estimate fear-avoidance/kinesophobia respectivly before and after and respecivly before and 12 month after the rehabilitationcourse. The study had a describing prospecitive design. Data was collected by the Swedish version of Tampascale for kinesophobia.

Twitching is frequently used in horse management because of its sedating and pain-relieving effects. In this study, the effects on the horse?s nervous system by twitching were investigated by thermography of the skin temperature. The temperature is regulated by the sympathetic nervous system through postganglionic sfincters at the capillaries of the skin. The effects on the endocrine activity have also been studied by the measuring of ACTH and cortisol in blood plasma.

The background to the study is that within the next ten years about 50 new multi-purposeindoor arenas will be built. These are used for various events such as sports, concerts, etc. In order to achieve a high level of security in the case of danger alarm signals and alarmmessages must be heard well by the visitors. ÅF-Ingemansson wanted to show builders the importance of good speech perception and that it is not observed in arenas today. They conducted technical tests on two large multi purpose indoor arenas to develop parameters that affect speech perception in the arena.To get a subjective view of how these arenas are experienced a survey was created.

Shock absorber units play a key role in establishing the driving dynamics and performance of automobiles. Öhlins Racing has manufactured high-tech automotive shock absorbers for over 30 years. Öhlins Racing?s advanced technology has contributed to over 200 world championships in automobile racing. Öhlin?s manufacturing process has long utilized automated fluid filling equipment during the final shock absorber unit assembly stage. The filling process consists of vacuum pumping the shock absorber unit and subsequent transfer of fluid. Vacuum pumping is necessary to remove residual air from the shock absorber unit prior to initiating the liquid filling stage. The presence of undesirable gases drastically compromises the performance of a shock absorber. The filling degree, defined as the final ratio of air to oil, is determined by the specific filling protocol as well as the specific equipment utilized.The current investigation aims to develop a viable technique to accurately determine residual air content in shock absorber units. If the filling degree can be appropriately quantified for a specific manufacturing process, then the air/oil ratio may be quantitatively related to shock absorber performance. The utilized measurement method must be completely integrated into the manufacturing process to guarantee shock absorber performance specifications according to the manufacturer?s standards. By utilizing the measurement method developed in this work, the manufacturing process, manufacturing equipment and product specifications can all be tailored to provide improved filling conditions.The developed measurement method provides accurate quantification of the filling degree under a wide range of processing conditions. The method establishes the relative quantity of air in the shock absorber unit by performing in-situ compressibility tests. The fill ratio can be controlled and varied by manipulating the vacuum pressure exerted during the filling process. Performance tests, however, indicate no correlation between filling degree and unit performance..

The purpose of this paper was to investigate whether Suzanne Retzinger?s linguistic cues for shame and verbal behaviors for hiding shame could be used to measure shame in surveys based on Thomas Scheff?s theory of shame. I created a measurement instrument consisting of 30 statements, which were all meant to measure general shame.The instrument was administrated to 180 respondents studying at Karlstad University, of whom 4 respondents were removed from the data set due to lack of standardization. With the polytomous rasch model used for the analysis, data from 176 respondents were analyzed, of whom 124 respondents were female and 52 were male.The result showed that the measurement instrument?s statements should not be used together because the analysis indicated multidimensionality.

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines.After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference intervals was questioned. Therefore new reference intervals for both urinary catecholamines and methylated catecholamines were developed by analysis of 46 samples using HPLC.

Studiens övergripande syfte är "Att ur ett livsloppsperspektiv beskriva och analysera äldre personers erfarenheter av och berättelser om psykisk ohälsa och hur de upplever att den påverkar åldrandet". De ursprungliga frågeställningarna var: "Hur upplever äldre personer att åldras med psykisk ohälsa?" och "Hur kan psykisk ohälsa bland äldre förstås ur ett livsloppsperspektiv?". Under studiens gång utkristalliserades en tredje frågeställning som ett analytiskt resultat av datamaterialet. Den lyder: "Vilka livsstrategier använder dessa personer för att hantera sina liv med psykisk ohälsa?"Sex personer mellan 65 och 85 år intervjuades om sin subjektiva erfarenhet av att leva med psykisk ohälsa.

ABSTRACTIntroduction: An increasing number of patients in Sweden receive epidural anaesthesia (EDA) in connection to surgery. Caring for patients with acute pain is a responsibility that is strongly established within the profession of the nurse anaesthetist. If the care provided by the nurse anaesthetist for patients who receive epidural anaesthesia is to evolve then further insight and knowledge is required regarding the individual´s experience.Aim: To describe patients' experiences in receiving epidural anaesthesia based on an earlier perioperative start-up of the EDA.Method: Based on a qualitative approach, the aim is to conduct semi-structured interviews with patients who receive EDA in connection to abdominal or gynaecological surgery. Research subjects' statements in the context of the interviews will be transcribed and then analysed using qualitative content analysis. In order to evaluate the chosen method regarding data collection and analysis model an exploratory pilot study was conducted.
