    Crystallization of beta-FEF3.3H2O in mixtures of nitric and hydrofluoric acid2005In: VDI-Berichte 1901, V D I Verlag GmbH , 2005, p. 17-22Conference paper (Refereed)
    Abstract [en]

    The solubility of β-heh 3·3H 2U has been measured in solutions with a range of different hydrofluoric acid concentrations (2, 4 and 6 mol/kg) and constant nitric acid concentration (3 mol/kg) in order to calculate a solubility constant applicable at the present ionic strength and temperature. Crystal growth of β-FeF 3·3H 2O has been measured in 3molal hydrofluoric acid and 3molal nitric acid solutions at 50°C by performing seeded isothermal desupersaturation experiments (1 < S < 3). The supersaturation was recorded by taking out solution samples which were analysed for total iron concentration with inductively coupled plasma atomic emission spectrometry (ICP-AES). The true supersaturation driving force was estimated by a proper speciation to account for the complexation, using the software SSPEC and relevant stability constants. Parameters of a desired growth rate equation were estimated by fitting the supersaturation balance equation directly to the supersaturation measurements. The results show that growth of β-FeF 3·3H 2O follows a parabolic rate law (g= 2,0 ±0,2). The growth rate at S= 2 was found to be 4,6×10- 11 m/s (50°C). The growth order and the low value of the growth rate suggest that the rate is surface integration controlled.

    Solubility of beta-FeF3 center dot 3H(2)O in mixtures of nitric and hydrofluoric acid2006In: Journal of Chemical and Engineering Data, ISSN 0021-9568, E-ISSN 1520-5134, Vol. 51, no 1, p. 223-229Article in journal (Refereed)
    Abstract [en]

    The solubility of beta-FeF(3) center dot 3H(2)O has been measured in solutions with different concentrations of nitric acid (0 to 7 in) and hydrofluoric acid (1 to 6 m) at the temperatures of (30, 40, and 50) degrees C. The total iron concentration at equilibrium was measured with inductively coupled plasma (ICP) spectroscopy. The solubility was evaluated in terms of the stepwise complexation of iron by fluoride ions at different ionic strength and temperature. The solubility of beta-FeF3-3H(2)O increases with decreasing concentration of HF and HNO3 and increasing temperature.

    Team: hur och varför?2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Under de senaste decennierna har det blivit allt populärare att organisera olika typer av verk­samheter i team. Vår avsikt med detta examensarbete var att skapa en förståelse för vad ett team är, när team är det bästa arbetssättet, hur man förankrar ett team samt vilka faktorer organisationer bör ta i beaktande i strävan att skapa ett väl fungerande team. I vår empiriska undersökning genomfördes semistrukturerade intervjuer med ledningen och teamledarna inom en organisation som nyligen infört en teambaserad organisation. I resultaten speglas ledningens och teamledarnas upplevelser av denna process. Våra resultat visar att det finns många faktorer som bör tas i beaktande då man organiserar verksamheten i team. Det som ter sig mest problematisk i den här skildrade processen är att hitta en balans mellan tillräckliga riktlinjer för teamen samtidigt som att ge dem tillräcklig autonomi för att de ska känna sig delaktiga. Ett sätt att hantera problematiken skulle kunna vara att ledningen försöker se till de individuella behoven hos respektive teamledare för att utifrån dessa komma fram till vilket stöd och vilken typ av riktlinjer som skulle kunna vara lämpliga. Teamledarna skulle också kunna ta hjälp av varandra för att tillsammans definiera rollen, få en klarare bild av vad upp­giften innebär och vilka behov de har för att kunna leva upp till egna och andras förvänt­ningar.

    Kost, kön och prestation: En studie om årskurs nio elevers kostvanor i olika inkomstområden2010Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med detta examensarbete är att undersöka årskurs nio elevers matvanor, och betyg i ämnet i idrott och hälsa utifrån genus. Studien genomfördes på två stycken skolor den ena i ett område med lågt socioekonomiskt index och den andra i ett område med högt socioekonomiskt index. Examensarbetet genomfördes med hjälp av information sammanställt från 77 stycken enkäter, betyg och relevant litteratur. Resultat av undersökning visar att det finns viss korrelation mellan elever som lever i områden med högt socioekonomiskt index har högre betyg i ämnet idrott och hälsa och god kosthållning i jämförelse med elever som bor i områden med lågt socioekonomiskt index som har lägre betyg och sämre kosthållning, dock går sambandet inte att säkert fastslå. Resultaten av studien visar att eleverna på skolan med lågt socioekonomiskt index äter mer onyttig mat och betydligt mindre frukost i jämförelse med eleverna på skolan med högt socioekonomiskt index. Resultaten visar också att flickornas och pojkarnas kostvanor skiljer sig på båda skolorna.

    Slow sand filtration as a water treatment method: An inventorying study of slow sand filters purification rates in rural areas in Colombia2015Independent thesis Basic level (university diploma), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Clean water is essential for health and the living in general for humans. For some people the access of clean and fresh water is a simplicity but for others, the lack of clean water, especially in rural areas creates one of the biggest humanitarian problems in the world today. For example a child under the age of five dies every 20 seconds today, due to water-related diseases. For areas with widespread poverty and poor living conditions it has shown that the access of clean water is a fundamental factor in order to increase the living situation and for the area to start develop. UNESCO claims that is possible to extinguish about 10 % of all diseases worldwide by implementing water treatment methods and sanitation facilities in vulnerable areas in order to improve the water quality. And reports from WHO and UNESCO shows that there is a clear connection between access to clean water and economic growth for a developing country.

    One of the oldest methods of water treatment is slow sand filtration (SSF) also known as biological sand filtration (BSF). The method is adapted from nature’s own way of treating water by filtration and has been used artificially by humans since the beginning of the nineteenth century. The SSFs in this study is a simple two-tank system where one tank is filled with sand and gravel and the other tank is working as a water reservoir tank. Under suitable circumstances this type of slow sand filters is a very effective water treatment method purifying the water with both mechanical and biological processes.

    In a rural area where Rio las Ceibas is flowing in the region Huila in Colombia, an environmental authority called La CAM is running a project where SSFs is implemented as a water treatment method at individual households. La CAM is in need of a pre-study in order to inventory some filters in the valley, to find out the purification rate of the filters and to get recommendations for further development of the SSF project. The purpose of this study was to examine the general status of the SSFs, find out about the households maintenance routines and knowledge of the SSF and to evaluate if the water quality produced by the SSFs is at drinking standard according to chemical and biological parameters. The methods used for achieving this purpose was by practical examinations, performing interviews and analysing water samples from the SSF system.

    In general the filters purified the water very poor and some filters even made the drinking water more contaminated than the raw water inlet. The study showed that many filters could reduce some of the chemical and biological parameters but no filter produced water according to the recommended drinking standard. The filters was most effective against turbidity and some filters reduced coliform bacteria very effectively. The filters general status was good but almost no filter had the required sand height or grain size. The interview study showed that the households considered clean water to be important in their homes and consider the SSF to have facilitated their lives. The households had some knowledge how the SSF function but had in general no routines on cleaning or maintaining the filter.

    For continued development of the SSF project it’s recommended to fill the filters with finer sand grains (0,2 – 0,45 mm), to at least a sand height of 40 cm, to spread more knowledge about maintenance of the filters and to continue to keep a regularly contact with the households to monitoring the status of the filters and also to maintain the relation between the household and the authority.

    Water treatment at personal level: An examination of five products intended for a small scale, personal point-of-use2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Water, and particularly clean water is essential for humans with a profound effect on health and has the capacity to reduce illnesses. Paradoxical, water is a medium where disease causing agents could be transmitted into the human body. Water can cause illness both from distribution of pathogenic organisms into the human system and also if not consumed in a required amount, leading to dehydration and other complications. Today catastrophes and disasters hit different areas in various forms. When such an event occurs, infrastructure is often disturbed or destroyed, and the supply of fresh water may be threatened.

    The Swedish Civil Contingencies Agency (MSB) is a government agency in Sweden, with a task to developing the community’ssocietal ability to prevent and handle emergencies, accidents and crises. The agency support various actors when a crisis or an accident occurs, both abroad and at a national level. The personnelal supporting at a crisis zone is sometimes working under extreme conditions where basic needs, such as access to food and fresh water can be a deficiency. To ensure that the personnel working at these sites can continue to solve problems without risking their own health caused by dehydration or other waterborne diseases, different methods can be used to treat water for personal use.

    Five different products intended for personal water treatment are chlorine dioxide pills, chlorine dioxide liquid, the Katadyn filter bottle, the Lifesaver filter bottle and the UV-lamp SteriPEN. These products use different water treatment techniques to purify water and secure the access to fresh water during exposed conditions. The aim with this study is to create an information basis in order for MSB to choose water treatment product for their future international missions. This is done by examine four parameters of these different products; purification capacity, manageability, environmental impact and economic aspects.

    The study showed that there is no product that pervading is best according to all parameters, they all have their pros and cons. The product that was best on average throughout the whole study is the SteriPEN but only if used during 10 or more missions. If a product should be used for only five or fewer missions, the chlorine dioxide liquid is recommended to use.

    At sites where the raw water is heavily contaminated a combination of two products could be an option, as a result of this thesis it is recommended to combine the chlorine dioxide liquid and the SteriPEN.

    This study is done qualitative and the result is based on literature, laboratorial reports and own measurements and calculations. Actual field tests are needed to further evaluate the products. The importance is that the product functions practically during MSBs working conditions, so relief workers really applicate the product to purify water and not refrain because it is not compatible with the working situations. If the product isn’t used because of these reasons it shouldn’t be used because it puts the relief workers at health risks.

    Sex utan lust till samlevnad. En kvalitativ studie om bedrivande av och problematik i sex- och samlevnadsundervisningen2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Ämnen kopplade till sexualitet och relationer är populära att diskutera i samhället, och i och med kampanjen ”Metoo” så synliggörs också vikten av kunskap om jämställdhet och respekt. Mycket ansvar ligger på skolan att utbilda demokratiska medborgare med sunda värderingar som kan ta kloka beslut. Sex och samlevnad är ett ämnesövergripande ämne, och i biolog och i naturkunskap har ämnet en viktig plats i kursplanen. Studier visar att sex- och samlevnads-undervisningen varierar på svenska skolor. De visar också att sex och samlevnad är ett känsligt ämne att prata om både för lärare och elever, och även att lärare inte alltid får verktyg från lärarutbildningen i hur de ska bedriva undervisningen. Därmed uppfylls inte målet om att Sverige ska ha en likvärdig skola. Denna studie syftade till att ta reda på vad lärare fokuserar på i sin sex- och samlevnadsundervisning samt vilka didaktiska val de gör. Vidare undersöktes hur lärarna bedömer elevernas kunskaper i ämnet, och slutligen har eventuella problem i sex- och samlevnadsundervisningen undersökts och hur de i så fall hanteras.

    Studien visade att sex- och samlevnadsundervisningen inte var likvärdig mellan och inom skolorna samt att lärarnas kunskaper om hur undervisningen ska bedrivas är bristfällig då de inte alltid följer de styrdokument som finns. Flera lärare var också omedvetna om att deras sätt att undervisa utgick från traditionella perspektiv på genus och sexualitet. Ingen av lärarna hade fått några verktyg i hur sex och samlevnad kan bedrivas på sin lärarutbildning, och ett annat problem som framkom var att det inte heller fanns någon närvarande rektor som ansvarade för att sex- och samlevnadsundervisningen höll hög kvalitet. Eftersom ämnet är så pass viktigt i samhället kommer det därför att behöva prioriteras mer. Lärarna behöver mer utbildning i hur man kan ta upp ämnet och få bättre didaktiska verktyg för att öka elevers inlärning och förståelse, och sex och samlevnad behöver få större plats i hela skolan.

    Friskt vågat, hälften vunnet: En kvalitativ studie om hur lärare i idrott och hälsa tolkar och undervisar om psykisk hälsa2019Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Idrott och hälsa syftar till att ge elever kunskaper i att kunna ansvara för sin egen hälsa. För att eleverna ska kunna ansvara för sin egen hälsa efter skolans år måste de bli förberedda för det samhälle som väntar. Den psykiska ohälsan har ökat dramatiskt i samhället, trots det har studier påvisat att psykisk hälsa är det som lärare i idrott och hälsa lägger minst vikt vid i hälsoundervisningen. Studien syftar därför till att undersöka hur lärare tolkar styrdokumenten samt hur de bedriver undervisning kopplat till psykisk hälsa. Studien undersöker också vilka verktyg lärare har fått från bland annat lärarutbildningen för att bedriva en hälsoundervisning och då med fokus på psykisk hälsa. Resultatet visar att lärare är medvetna om vad som krävs för att bedriva undervisning som ger elever kunskap att ansvara för sin psykiska hälsa. Dock visar resultatet även att lärarna inte är förmögna att praktisk genomföra undervisningen utifrån sina visioner. De verktyg som lärarna har fått på lärarutbildningen är inte längre relevanta vilket tyder på att hälsoundervisningen utbildar elever till ett samhälle som inte längre är aktuellt

    Informationskompetens i det svenska och bayerska gymnasiet: En jämförande analys av det svenska och det bayerska gymnasiets läro- och ämnesplaner2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study is a comparative study of the occurrence and function of information literacy in the curricula of the Swedish and Bavarian Gymnasium and investigates the occurrence of the term ”information literacy” and shows through what other linguistic means the notion of information literacy is expressed in the curricula. The study also wishes to analyze how the notion of information literacy manifests itself in the different school systems. Relevant textual passages of both curricula are compared to each other through the theoretic lens of Bruce’s phenomenographic model of information literacy. This study shows that although the term of ”information literacy” is absent in the analyzed texts several other terms are used in both curricula to express similar notions.

    The study further shows that although all seven of Bruce’s conceptions of information literacy are represented in the curricula some major differences exist between the two educational systems. Thus the analysis shows differences in the use of information technology which in the Swedish curriculum is seen as an educational goal in the individual subjects whereas according to the Bavarian curriculum training in the use of information technology takes place in the subject of Informatik. Other differences concerning information literacy are shown through the notion of the control concept. Here it is shown that in the Bavarian curriculum emphasis has been put on the training of the memory capacity of the student as a form of information organization. Bruce’s wisdom conception is further used to show that the Bavarian curriculum emphasizes the use of subject knowledge for democratic purposes. This is shown most clearly in the syllabi of the humanities to be seen.

    Through the use of Bruce’s conceptions it can also be shown that both in a Swedish and a Bavarian context information retrieval is partly absent in the natural science syllabi, whereas it plays a major part in the syllabi of the humanities. This can be connected to a common lack of faith in the value of information retrieval in the natural sciences. This is a two years master’s thesis in library and information science.

    Kritik, vad innebär det?: En studie som kartlägger kvinnors upplevelser av kritik på arbetsplatsen2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to create an understanding of how women in female dominated workplaces are experiencing criticism. The study will be a field study which is examining women who are active in preschool, when previous research has demonstrated a clear majority of women in this profession.

    The intention of this study is not to create any objective truth of reality, however, relate this study to interpret and describe any phenomena related to the topic, and create an understanding of the individual's perception of the concept.

    The informants were chosen strategically, further characterized the informants' participation of self-selection. It will not take into account, variables other than gender in terms of selection.

    Theories that the study rests on is the symbolic interactionism, which, among other things, its view of rationality is treated. Furthermore the theory of Johan Asplund, social responsivity, is taken into consideration and, finally, Erving Goffman's theory of identity formation.

    The conclusions to be drawn, in and of this study is that the relations between individuals in a group seems to have a major impact on how people perceive criticism. To avoid misunderstandings about the chosen topic appears public opinion, advise that the "definition of the situation" is something you should take into consideration, so where the spontaneous reaction of criticism is negative.

    En förståelse för begreppet hållbar utveckling2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I skollagen står ingenting om hållbar utveckling eller undervisning för hållbar utveckling.Däremot står det klart och tydligt i läroplanen för grundskolan, förskoleklassen ochfritidshemmet 2011 (Lgr11) att eleverna ska få kunskaper om vad som behövs för att skapa engod miljö och en hållbar utveckling (Skolverket, 2011 s. 14). Vidare finns det i kursplanerna förde samhällsorienterade ämnena att alla elever efter årskurs tre, ska besitta kunskaper om hur manskapar en god miljö och en hållbar utveckling (Skolverket, 2011 s. 204). Ingenstans står det dockvad en god miljö är och vad en hållbar utveckling innebär. Det är i den här otydligheten som dethär arbetet har vuxit fram och syftet är att ta reda på vad forskare säger om begreppet samt hurdet har förändrats och förändrat skolan. Det visade sig dock att begreppet är väldigtsvårdefinierat och av denna anledning går det heller inte att slå fast vid en definition eller ett rättsätt. Målet har istället varit att se på förändringar i styrdokument och skapa en struktur av alla deutsagor om hållbar utveckling som forskare har bidragit med.

    Planet Rendering Using Online High-Resolution Datasets2008Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    A large amount of image datasets are publicly available online through the web map service standard. The contents of the datasets span from satellite imagery of the earth and other planets of our solar system to various scientific data.

    This thesis presents an implementation of a planet renderer streaming high resolution image and height data from online datasets. The planet renderer uses a level of detail technique based on nodes connected by a quad tree data structure. The level of detail is determined by the size of the nodes in screen coordinates which ensures a sufficient texel to pixel ratio of the image data and a reasonably consistent polygon size in screen space.

    The project will be implemented in Uniview which is an application developed by SCISS AB and is primarily used in planetarium domes to visualize the Universe. Being able to visualize the high resolution image data and scientific measurements in a dome environment will provide the viewers a greater perspective of the data.

    Extending IMS specifications based on the charging needs of IPTV2006Independent thesis Basic level (professional degree), 20 points / 30 hpStudent thesis
    Abstract [en]

    With the standardization of IP Multimedia Subsystem (IMS), the telecommunications scene becomes more and more converged and in the future we will most likely access our services from all kinds of devices and link them together. One important future access method that has so far been left out of the standardization is television. There is a need for Internet Protocol Television (IPTV) to work together with IMS and this thesis focuses on one aspect of that convergence, namely charging.

    The problem explored in this thesis is if there is an efficient way of charging for IPTV services while taking advantage of the IMS charging functionality and this is done for two aspects of the problem. First, the possiblilty of an efficient Session Initiation Protocol (SIP) signaling schema is investigated and then a good charging Application Programming Interface (API) to be used when developing applications is investigated. The findings of these two investigations are then tested and improved during the implementation of a demo application.

    This thesis delivers specifications for a signaling schema that enables a Set-Top Box (STB) to pass charging information to an IMS network via INFO requests inside a special charging session. The schema is small and extendable to ensure that it can be modified further on if necessary. The thesis also delivers an encapsulating and intuitive charging API to be used by developers who want to charge for their services.

    Long-term retention of neurotoxic ß-carbolines in brain neuromelanin2003In: Journal of neural transmission, ISSN 0300-9564, E-ISSN 1435-1463, Vol. 111, no 2, p. 141-157Article in journal (Refereed)
    Abstract [en]

    beta-Carbolines show structural resemblance to the neurotoxic N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and are metabolized to mitochondrial toxicants. Humans are continuously exposed to low levels of beta-carbolines through cooked food, coffee, alcoholic beverages and tobacco smoke. beta-Carbolines have previously been detected in higher levels in the pigmented substantia nigra than in the cortex of humans. The distribution of 3H-labelled harman and norharman in the brain of pigmented and albino mice and in frogs (a species having neuromelanin) was studied by tape-section and light-microscopic autoradiography. Furthermore, the binding of these beta-carbolines to dopamine-melanin and melanin granules from Sepia officinalis was examined. The results revealed a high affinity binding to melanin and a long-term retention (up to 30 days) in pigmented tissues, including neuromelanin-containing neurons of frogs after a single injection. The role of long-term exposure to food-related beta-carbolines and a retention of these compounds in pigment-containing neurons in the induction of idiopathic Parkinson's disease should be further considered.

    Investeringsrådgivare och finansiell risktolerans: - En studie om svenska investeringsrådgivares rutiner kring bedömning av individuella kunders finansiella risktolerans2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Inledning: Den explosionsartade ökningen av nya, mer komplexa finansiella instrument har ökat kravet på de enskilda investerarnas kunskaper. Detta har i sin tur ökat efterfrågan på investeringsrådgivning från professionella rådgivare. Som ett resultat av den ökade efterfrågan har även antalet aktörer som ägnar sig åt investeringsrådgivning ökat på senare år. Ett grundläggande krav för att rådgivaren skall kunna förse individuella kunder med individanpassade investeringsråd är en korrekt bedömning av kundens finansiella risktolerans. En bedömning som i sin tur är starkt beroende av hur rutinerna kring insamling av nödvändig information från kund ser ut; bakgrundsanalysrutinen. Till följd av dagens form av reglering har individuella bolag ett stort eget ansvar och utrymme att utveckla sina egna rutiner. Eftersom investeringsrådgivning erbjuds av allt ifrån multinationella finanskoncerner till lokala rådgivningsbolag samt av rådgivare med många olika egenskaper finns det många olika faktorer som potentiellt kan påverka hur rutinerna ser ut. I takt med att antalet aktörer ökat kan även antalet rutiner ha ökat, potentiellt med varierande kvalitet.

     

    Problemformulering:

    Hur ser svenska investeringsrådgivares rutiner ut för att kategorisera sina kunder i termer av finansiell risktolerans inför investeringsrådgivning?

     

    Hur effektiva är svenska investeringsrådgivare på att bedöma individuella kunders finansiella risktolerans i jämförelse med vad befintliga teorier och empiriska studier inom området förespråkar?

     

    Vilka bolagsspecifika och rådgivarspecifika faktorer ligger bakom potentiella rutinvariationer?

     

    Syfte: Syftet med denna studie är att bidra till att överbrygga det kunskapsgap som existerar i befintlig litteratur samt tillfredsställa efterfrågan på studier kring hur och hur effektivt, i jämförelse med en modell härledd från befintliga teorier och empiriska studier, investeringsrådgivare först bedömer och sedan kategoriserar individuella kunder i termer av finansiell risktolerans inför investeringsrådgivning. Vidare ämnar denna studie att utröna vilka bolagsspecifika och rådgivarspecifika faktorer som ligger bakom potentiella variationer i investeringsrådgivares rutiner gällande bedömning och kategorisering av kunder, i termer av finansiell risktolerans, inför investeringsrådgivning.

     

    Metod: Denna studie har anammat en kvantitativ undersökningsmetod där det empiriska materialet är insamlat med hjälp av en webbenkät riktad mot svenska investeringsrådgivare.

     

    Resultat och slutsatser: Resultatet av denna studie påvisade att två tredjedelar av respondenterna innehar rutiner som kan betraktas som någon grad av effektiv, samtidigt som resterande (en tredjedel) inte har det. Vi kunde också urskilja ett positivt samband mellan både rådgivarens erfarenhet av rådgivaryrket samt rådgivarens kunskapsnivå och en mer effektiv eller grundligare bedömning av individuella kunder

    Sex- och samliv för personer med multipel skleros: en litteraturöversikt2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund

    Att ges möjligheter att bejaka sin sexualitet är en mänsklig rättighet som kan komma att äventyras vid sjukdom. Multipel skleros är en kronisk och degenerativ sjukdom i centrala nervsystemet som påverkar kroppens normala funktioner. Många personer med multipel skleros lider av sexuell dysfunktion, fatigue, känselrubbningar och ångest. Sjuksköterskans personcentrerade förhållningssätt ska utgå ifrån hela människan och dennes livsvärld.

    Syfte

    Syftet med litteraturöversikten var att belysa faktorer som påverkar sex- och samlivet för personer med multipel skleros.

    Metod

    Allmän litteraturöversikt valdes som metod. Databassökningar gjordes i PubMed, CinAHL och PsychINFO. Resultatet baserades på 16 inkluderade artiklar. Dessa artiklar bearbetades, kvalitetsgranskades och sammanställdes i en matris. Dataanalys omfattade granskning, sammanställning av artiklarnas resultat, identifiering av essens och en jämförande analys som resulterade i beskrivande kategorier.

    Resultat

    Flera faktorer påverkade sex- och samlivet för personer med multipel skleros. Resultatet presenteras i fem kategorier: "en förändrad kropp" , "att inte uppleva lust", "en förändrad självbild", "sjukvårdens bristande engagemang" och "anhörigas stöd".

    Slutsats

    Sex- och samlivet för personer med multipel skleros påverkades negativt av deras förändrade kropp, självbild och upplevelse av lust. Sjukvården tenderade att ignorera området vilket också var en faktor som påverkade tillvaron. Personernas närmast anhöriga hade möjligheter att främja sex- och samlivet genom en god kommunikation och stöd. Belysta faktorer ger en bredare förståelse för patientgruppen och deras tillvaro. Denna förståelse förväntas utveckla sjuksköterskans möjligheter att tillämpa ett personcentrerat förhållningssätt i omvårdnaden för dessa personer.

    Järv, lodjur och varg i renskötselområdet: inventeringsresultat 20012001Report (Other academic)
    Abstract [sv]

    För sjätte året i rad har länsstyrelserna i Norrbottens-, Västerbottens-, Jämtlands- och Dalarnas län i samarbete med samebyarna i Sverige inventerat renskötselområdet påförekomst och föryngring av järv, lodjur och varg. Inventeringsmetoderna har under tiden sedan 1996 reviderats och förfinats och samma metodik används i alla län i renskötselområdet(och även i Norge).Resultatet av arbetet skall användas i följande hänseenden:1. Underlag för Sametingets beslut om fördelning av ersättningar för rovdjur till samebyarna.2. Underlag för Naturvårdsverkets beslut om var och hur stor omfattningen ska vara av eventuell skyddsjakt.3. Uppföljning av effekterna av beviljad skyddsjakt.4. Möjliggöra ansvarsfull förvaltning genom ökad kunskap om de stora rovdjuren i renskötselområdet.5. Uppföljning av de nationella målen om rovdjursförekomst och beståndsstorlek.År 2001 dokumenterades 50 föryngringar av järv i renskötselområdet i Sverige. Dessutomdokumenterades sex järvföryngringar inom 5 km in på norsk sida och ytterligare fem i konventionsbetesområden i Norge. Alla dessa är ersättningsberättigande i det svenskaersättningssystemet. Antalet järvföryngringar har ökat något sedan år 2000 efter att fram till dess ha uppvisat en starkt minskande trend. Uppgången har skett i Norrbotten. Trots detta är det ändå tydligt att antalet järvföryngringar har minskat sedan 1996. Det finns nu drygthälften av de 90 järvföryngringar som utgör det nationella etappmålet. Det totala antalet järvar i renskötselområdet år 2001 uppskattas grovt till drygt 300 individer(exklusive årsungar).Antalet familjegrupper av lodjur som dokumenterades i renskötselområdet i Sverige var 131 stycken. Dessutom dokumenterades ytterligare sex i konventionsbetesområden i Norge. Antalet familjegrupper av lodjur har ökat i Norrbotten och i Västerbotten jämfört med ifjol. IJämtland har dock lodjuren fortsatt att minska vilket gjort att det totala antalet familjegrupperi princip är detsamma år 2001 som år 2000. Sedan 1996 har dock lodjursbeståndet i renskötselområdet minskat. Det har bedrivits en omfattande skyddsjakt på lodjur vilketbedöms vara en orsak till minskningen. Det totala antalet lodjur i renskötselområdet år 2001uppskattas grovt till ca 800 individer (inklusive årsungar).Tillfällig vargförekomst har dokumenterats i totalt nio samebyar fördelat på samtliga län.Förekomst av björn och kungsörn rapporteras i samtliga samebyar.Den minskade medelstilldelningen till länsstyrelserna under de senaste åren har medfört attdet varit svårt att bibehålla kvaliteten på inventeringarna. Främst gäller detta lodjursinventeringen. År 2001 anvisades 3 miljoner kronor till länsstyrelserna i fjällänen för inventeringsverksamheten. Samebyarna tilldelades år 2001 via Sametinget 3 miljoner förinventeringsarbetet kopplat till ersättningssystemet.

    Selective Retention of β-Carbolines and 7,12-Dimethylbenz[a]anthracene in the Brain: Role of Neuromelanin and Cytochrome P450 for Toxicity2005Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The ß-carbolines norharman and harman structurally resemble the synthetic compound 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) that is known for its ability to damage neuromelanin-containing dopaminergic neurons of the substantia nigra and thereby induce parkinsonism. MPTP is, however, not normally present in the environment whereas the ß-carbolines are present in cooked food and tobacco smoke.

    In this thesis it was demonstrated that norharman and harman had affinity to melanin and were retained in neuromelanin-containing neurons of frogs up to 30 days post-injection (the longest survival time examined). It was also demonstrated that norharman induced neurodegeneration, activation of glia cells and motor impairment in mice. Furthermore, this compound induced ER stress and cell death in PC12 cells. An in vitro model of dopamine melanin-loaded PC12 cells was developed in order to study the effect of melanin on norharman-induced toxicity. In this model, melanin seemed to attenuate toxicity induced by low concentrations of norharman. After exposure to the highest concentration of norharman, melanin clusters were disaggregated and there was an increased expression of stress proteins and caspases-3, known to be involved in apoptosis.

    The polycyclic aromatic hydrocarbon, 7,12-dimethylbenz[a]anthracene was demonstrated to have a CYP1A1-dependent localization in endothelial cells in the choroid plexus, in the veins in the leptomeninges and in the cerebral veins of mice pre-treated with CYP1-inducers.

    These results demonstrate that the distribution of environmental compounds could be influenced by the presence of neuromelanin and expression of CYP enzymes in the brain and that norharman may induce neurotoxic effects in vivo and in vitro.

    Norharman-induced motoric impairment in mice: Neurodegeneration and glial activation in substantia nigra2006In: Journal of neural transmission, ISSN 0300-9564, E-ISSN 1435-1463, Vol. 113, no 3, p. 313-329Article in journal (Refereed)
    Abstract [en]

    The beta-carboline norharman is present in cooked food and tobacco smoke and show structural resemblance to the neurotoxicant 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. C57BL/6 mice were injected subcutaneously with norharman (3 and 10 mg/kg) twice per day for five consecutive days. Eighteen hours after the last dose an increased expression of glial fibrillary acidic protein and fluoro-jade staining were demonstrated whereas the number of tyrosine hydroxylase positive cells were unchanged in the substantia nigra. Two weeks after the last treatment a decreased motor activity was observed whereas cognitive functions remained intact. In cultured PC12 cells norharman treatment induced mitochondrial dysfunction and increased the number of caspase-3 and TUNEL-positive cells. The results demonstrate that norharman induced apoptosis in cultured cells as well as early neurodegeneration, glial activation and sustained motor deficits in mice and suggest that exposure to norharman may contribute to idiopathic Parkinson's disease.

    Differential effects of dopamine melanin on norharman-induced toxicity in PC12 cells2007In: Journal of neural transmission, ISSN 0300-9564, E-ISSN 1435-1463, Vol. 114, no 7, p. 909-918Article in journal (Refereed)
    Abstract [en]

    The food contaminant norharman structurally resembles MPTP a compound that selectively damages pigmented brain areas. Both compounds are sequestered and retained in melanin-containing neurons. The aim of the study was to examine whether intracellular melanin can modulate the toxicity of norharman in melanin-loaded PC12 cells. Dopamine melanin protected against norharman-induced upregulation of grp78, activation of caspase 3 and necrosis at low concentrations (5 and 50 µM). In contrast, at a high conentration (500 µM) there was a significantly increased expression of grp78, hsp90 and caspase and a disassociation of melanin aggregates and dispersal of melanin granules to swollen neurite terminals. In human populations, a long-term low-level exposure to toxicants with a high affinity to melanin will probably result in accumulation in melanin-containing neurons in vivo. Our data suggest that accumulation of a neurotoxicant in melanin-loaded cells may lead to increased cell stress, apoptotic signaling and disassociation of melanin aggregates.

    Dopamine melanin-loaded PC12 cells: A model for studies on pigmented neurons of substantia nigra2005In: Pigment Cell Research, ISSN 1755-1471, E-ISSN 1755-148X, Vol. 18, no 4, p. 306-314Article in journal (Refereed)
    Abstract [en]

    The most conspicuous feature in idiopathic parkinsonism is the degeneration of pigmented neurons in the substantia nigra. A major problem for the study of the significance of neuromelanin for the development of parkinsonism is that common experimental animals lack neuromelanin in substantia nigra. The aim of this study was to develop an in vitro model that could be used to study the role of neuromelanin in chemically induced toxicity in dopaminergic cells. Cultured neuron-like PC12 cells were exposed to synthetic dopamine melanin (0-1.0 mg/ml) for 48 h, resulting in uptake of dopamine melanin particles into the cells. The intracellular distribution of dopamine melanin granules was similar to that found in neuromelanin-containing neurons. Dopamine melanin, up to 0.5 mg/ml, had negligible effects on ultrastructure, induction of the endoplasmic reticulum-stress protein glucose regulating protein 78, activation of caspase-3 and cell viability. The decreased cell viability in response to the cytotoxic peptide amyloid-beta25-35 was similar in melanin-loaded cells and in control cells without melanin. The results of the studies suggest that melanin-loaded PC12 cells can serve as an in vitro model for studies on the role of neuromelanin for the toxicity of chemicals, in particular neurotoxicants with melanin affinity, in pigmented neurons.

    Naturvärdesbedömning av Utanåfladen; En inventering av vårlekande fisk, bottenfauna och vegetation2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    There are several thousands shallow bays along the Swedish east coast. Most of them are disturbed by different human activities, and undisturbed bays can be considered as quite unique. In the sheltered shallow bays water warms up more rapidly than adjacent water favoring the growth of vegetation, which in turns is beneficial to spring spawning fish species like perch and pike. It is nowadays more common that coastal habitats are inventoried to facilitate future preservation and planning. The aim of this study was to investigate the shallow bay Utanåfladen (59° 53`31.38 N 19°00`44.90 E) in the north Stockholm archipelago and evaluate its habitat value. The study includes an inventory of vegetation, benthic fauna and spawning fish in the spring of 2014. Results show that Utanåfladen will be evaluated as a high valued area. The bay seems to be a good spawning area for both pike and perch. Stoneworts that are sensitive to eutrophication were also found in the area.
