Enzymatisk modifiering av fiskolja - jämförelse mellan olika lipaser.I detta arbete studerades tre olika lipaser som katalyserade en metanolysreaktion i fiskolja.Målet med arbetet var att finna ett specifikt lipas för produktion av en EPA/DHA fraktioner från fiskoljan i en metanolysreaktion få högt utbyte av Sn-2 monoglycerider av EPA och/eller DHA och med detta kunna möjliggöra uppkoncentrering av hälsoviktiga fettsyror jämföra reaktionen i normal och superkritisk atmosfär.Metanolysen ägde rum i normal och superkritisk atmosfär genom att oljan, enzymet och metanol blandades i respektive reaktorn.Sn-1,3 specifika lipaser var isolerade från Thermomyces lanuginosa (Lipozym TL IM från Novozymes, Danmark) och Rhizomucor miehei (Lypozym RM IM från Novozymes, Danmark ) och ospecifik lipas från Pseudamonas sp.(Amano-C från Amano Enzyme Inc. Japan). Alla enzymer var immobiliserade på jonbytare.I försöken användes ?Ledins? fiskolja som var köpt i en lokal affär. Oljan var en blandning extraherad från oceanernas olika fiskklasser.

Aim: To examine the reaction of extreme preterm infants with regarding to body temperature and transepidermal water loss during skin-to-skin care according to Kangaroo Mother Care (KMC) during the infant?s first week of life. Method: This was a descriptive quantitatively designed study, which was a pilot study within the framework of a larger project. Nine children, with a median gestational age of 24.91 weeks, were examined by measuring body temperature (axilla and skin temperature) as well as transepidermal water loss before, during and after KMC. Results: The study showed that skin temperature tended to rise during KMC, especially for those children who were nursed with KMC for more than 60 minutes.

Being able to predict the future had been an invaluable competitive advantage for any corporation. Forecasting is a vital part of any business, hence a good forecast allows enterprises to invest in a beneficial way. However, there are several ways to prepare forecasts and the forecast methodology can vary. An industry that is dependent on forecasts is the energy industry. By predicting consumers' energy consumption, Swedish energy companies can hedge on the Nordic power market Nord Pool.

The aim of this study was to investigate how selected municipalities? use social media, with a focus on how they are working to increase the dialogue between municipalities? and residents. To answer the purpose of the study three questions has been formulated: how do the communicators use social media in their daily work? What opportunities and challenges are the municipalities? experiencing with Facebook? How do they work with Facebook to increase dialogue with citizens?The theories that has been used in this study is Cutlip?s and Grunig?s public relations theories, Shannon and weavers communication model, Cutlip?s and Heath?s theory of issue management and Jenkins theory of convergence culture. The method that has been used in this study is qualitative semi-structured interviews and the analysis is done with a thematic text analysis.

This qualitative study aims to study how sexuality is constructed in web articles on the movie Fifty Shades of Grey. The study is based on a social constructivist perspective where language is seen as constitutive of reality. The study is based on a Foucauldian discourse analysis which is used in order to see what is excluded and included in the articles? construction of normal sexuality. The result shows that there are similarities in how the web articles produce normal sexuality.

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

AbstractIntroductionWedged shoe insoles are used as a treatment for different problems in order to change the ground reaction force. They can secondary cause different loading patterns under the foot compared to normal. No previous study has, to the author?s knowledge, clinically evaluated the plantar foot pressure with different full-length wedges in normal persons.PurposeThe purpose was to evaluate the plantar pressure with different degrees of full-length wedges in normal persons.MethodTwenty persons with normal feet have participated in this single blind study. Wedges were produced clinically in four different shapes, 3° valgus, 0° flat, 3° varus och 6° varus.

Hypertrophic cardiomyopathy (HCM) is the most common heart disease in cats. Maine coon is one of the breeds where the disease is overrepresented. Studies have shown that HCM is inherited as an autosomal dominant trait in Maine Coon cats. This finding has led to cardiac screening using ultrasound in the breed. The results of the screening are used in a national breeding program constructed to reduce the spread and incidence of HCM in Maine Coon cats.

This study describes the intellectual ability of a cohort consisting of 120 young women in compulsory care at a SiS institution in Sweden, tested and analyzed between January 2001 and May 2005. The women have been tested with the intelligence tests WISC-III or WAIS-R, as well as the personality trait tests BCT, CMPS and SCL-90, and the personality disorder test SCID-II. This material has been analyzed to investigate how these women's intellectual ability relates to other factors. The analyses show that the main difference between the women of this study and the normal population is their level of intelligence and presence of personality disorders. The IQ level of these women is statistically proven on an average one standard deviation lower than the normal population.

Benign Childhood Epilepsy with Centrotemporal Spikes - BCECTS is a common neurological syndrome but the possible cognitive effects are still relatively unknown. In the study 12 children with the diagnose BCECTS, 9 boys and 3 girls between the ages of 5,5 and 13,5 years, were examined. An extensive battery of neuropsychological tests were administered. The results indicates normal cognitive functioning as compared to the normal population, with one exception; an aspect of attention. But the results also indicate several negatively effected performances when compared to the cognitive g-factor of each child.

A Scenario Analysis Authors: Mellberg Ola, Technology Management, Lund UniversityMårtensson Jens, Technology Management, Lund University Tutors: Andersson Jens A, Faculty of Engineering LTHKarlberg Johan, Sony Ericsson Mobile Communication ABSvensson Claes, Lund University Discussion: The most significant impacts on the telecom industry over the past decades have been the rapid growth of the Internet and mobile telephone services. Currently these two worlds are converging. Moreover, the fast expansion of wireless high capacity Internet access, increased distribution of local/public hotspots and rapid development of wireless network cards have opened new opportunities for the mobile telecom industry. Research Questions:To what extent could the explosion of local and public wireless networks, using WiFi technology, affect the future telecom industry? Who will ultimately master the WiFi innovation and to what degree could this innovation open new possibilities for external players to enter the mobile voice industry? Purpose: The purpose of the Master Thesis is to provide Sony Ericsson Mobile Communication AB with the most transformational scenarios, which will enable employees to recognise patterns and interpret the meaning of WiFi-related events as they unfold.

It?s been noted that cows held at the section of ruminant medicine and epidemiology, Swedish University of Agricultural Sciences (IME), used for the education of veterinary students, have a lower heart rate than what is considered normal for ruminants. In this investigation the heart rates of seven lactating cows were recorded continuously during the period around drying off. The first recording took place at the farm from where the cows were bought, and then their heart rate was monitored after their arrival at IME and further on until they were completely dried off. The results were then compared to the heart rate of seven already dried off cows from the same farm.

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.

In this paper the rate of convergence, speed of execution and symplectic properties of the time-integrators Leap-Frog (LF2), fourth order Runge-Kutta(RK4) and Crank-Nicholson (CN2) have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). The results show that RK4 is the fastest in achieving higher tolerances, while CN2 is the fastest in achieving lower tolerances. Fourth order corrections of LF (LF4)and CN (CN4) were also studied, though these showed no improvements overLF2 and CN2. All methods were shown to exhibit symplectic behavior..

The cell cycle is the time a cell spends between two cell divisions. The cell cycle includes several parallel processes, all of which must be completed before a cell is mature for dividing. In the first place, all subcomponents (RNA, protein and membrane lipids) need to double in quantity and this occurs continuously through the cell cycle. Furthermore, the genome and some chromosomal proteins must double and this take place during a limited interval in the middle of the cell cycle (S-phase). On either side of the S-phase are two "gaps" which is called G1 and G2. When the cell has passed a point in the G-phase they are irreversibly programmed to progress through the remaining of the cell cycle and will undergo the next cell division. When a cell have passed a point in the G1 phase, approximately four hours after mitosis, a normal cell is in a state of indecision.
