Se mig, inte bara min cancer! : En systematisk litteraturstudie om bröstcancerpatienters upplevelser av möten med vårdpersonal.

Aim: The aim is to create a review that examines different forms of massage therapy and their effects on hypertension.Method: Literature review of 10 scientific articles on the subject of massage and its effects on blood pressure. The literature searches were made with PubMed and Cinahl using the keywords "massage therapy", "effects" and "blood pressure".Results: The articles showed that massage had a positive effect in lowering blood pressure. This could be explained by greater extent of relaxation in the participants investigated and an increased activity of parasympaticus and reduced secretion of stress hormones. The articles do not agree on what form of massage therapy is most effective in lowering blood pressure and it is uncertain for how long the effect can remain.Conclusion: Massage is usually seen as a treatment without scientific basis. There is evidence that suggests that massage therapy is an effective treatment for lowering blood pressure.

Teoretiska perspektiv på musik och insomning - En musikvetenskaplig litteraturstudie om möjliga förklarings- och förståelsemodeller

This essay constitutes a literary study investigating how scientific literature within thefield of musicology can benefit to the understanding of how people use music as anaid for sleep and relaxation. Furthermore it aims to answer the question of whatconclusions can be drawn about the music people choose to use in these types ofsituations. The essay depicts the phenomenon of sleep music from several anglesgathered from the literature and investigates several models of understanding howand why people use music as a tool for emotional influence. As a complement to this,and to illustrate the modern usage of music for mind-altering purposes, the essay alsostudies a selection of digital sleeping aids ? apps.The study shows a complexity since the phenomenon can be viewed from severalangles that are not always consistent with each other.

Förhandlingslösning som alternativ till fortsatt militär kamp : en studie av två irreguljära parters val

The Swedish Armed Forces tend to ask themselves if it is sufficiently multinational interoperablefor participation in international operations. An equally valid question today should be whether theSwedish Armed Forces are sufficiently nationally / internally interoperable, between their branchesof service, to be able to conduct independent operations based on the joint warfare theory.The lack of ability to joint warfare in the armed forces in general and the Swedish Armed Forcesspecially constitutes the essay´s fundamental problem. By using Codners and Sjöbloms custominteroperability theory, the Swedish Armed Forces documents were analyzed to highlight anyweaknesses related to joint warfare and national interoperability between Ground and Air Forces.The survey shows weaknesses linked to the custom theory and Swedish Armed Forces governingdocuments. The ability of a national interoperability is limited between Ground and Air Forcestoday, mostly because of weaknesses in the Swedish Armed Forces strategic concept which doesnot describe the importance of joint warfare at all levels sufficiently. This leads to deficienciesreflected in doctrines, regulations, technology, techniques and exercises.

Hur kan Matematisk Problemlösning Definieras?

När Energimyndigheten 2008 frågade ungdomar om förnybar energi kunde 40 % av de tillfrågade inte namnge en enda förnybar energikälla. Användandet av förnybar energi är en del av den strategi som Förenta Nationerna [FN] har lagt fram för att nå en hållbar utveckling i framtiden. FN framhäver även vikten och behovet av att undervisa om hållbar utveckling och förnybar energi.Vi ville studera vilka förnybara energikällor som förekom i läroböcker för grundskolans senare år och gymnasiet. Detta för att få en uppfattning om hur lärare kan använda läroböckerna i framtida undervisning om förnybar energi.Vi har gjort en kvantitativ innehållsanalys av energikapitlet i olika läroböcker där vi har studerat hur området förnybar energi presenterades, bland annat utifrån perspektivet scientific literacy.Våra resultat visar signifikanta skillnader mellan läroböckerna för gymnasiet och grundskolans senare år. Bland annat presenteras många fler energikällor i läroböckerna på gymnasiet, och de presenteras även på ett sådant sätt att de ingriper flera områden av perspektivet scientific literacy.

Varför är Bivarödsånsvatten så brunt?

The river Bivaröd is one of the river Helgeån tributaries which has the highest and the fastest increase in water colour. The reason behind this increase is unclear but several factors have been suggested to affect this pattern. In this work, I studied the role of land use, iron and precipitation for water colour increase in river Bivaröd for the period 1976 -2011. Data from a field study along with data from SRK for river Helgeån were used for the analyses. The results showed that both water colour and iron concentration increase and that there is a strong correlation between these two variables.

New Age och pseudovetenskap i tidskriften Sans -en analys

Critique regarding religious practices has become more and more apparent in today's society.Sans magazine has become a voice in the Swedish debate regarding religions undertakings and have received opposition from various directions. As Sans magazine, issue no.1, is accused of being islamophobic, the critique is focused on the internal discourse within the atheist and agnostic society. As Sans issue no.2 came out, it did not focus on Islam or any of the abrahamic religions but instead it discussed New age and the nature of pseudoscience.I sought to evolve the didactic discource regarding ?truth? and ?reality? by finding if thediscourse within Sans is apparent and if so, what it is based upon. The analysis also focuses onthe terms used to describe new age and pseudoscience.

Hur organiserar forskare sitt material? : Personlig informationshantering i en vetenskaplig forskningsmiljö

The domain of this thesis is Personal Information Management (PIM) which is a sub-domain to human-computer interaction (HCI) that specifically concerns the interaction between human and information. The purpose of the study is to make an exploration of information management in a scientific research setting, to study which tools and strategies for information interaction that are used in the context and to suggest possible improvements of today's practices. Three in-depth interviews with scientific researchers have been conducted followed by a qualitative analysis of the results. The results show that there are great variations among the three respondents and that there can be distinguished as much as 15 different dimensions that when put together forms a unique PIM profile for each individual. The recommendation following this is that tools for PIM have to allow a high degree of individualisation.

Elevers möte med det naturvetenskapliga arbetssättet

Syftet med denna studie är att undersöka hur elever samtalar när de möter en uppgift som syftar till att öva deras förmåga att använda ett naturvetenskapligt arbetssätt. Undersökningen genomfördes genom att fyra grupper om två elever fick en uppgift där de formulerade frågeställningar kring en isballong (en frusen vattenballong). Samtalen spelades in på band. Inspelningarna transkriberades och analyserades med hjälp av en praktisk epistemologisk analys utifrån tre olika kategorier: samtal inom diskursen, samtal om diskursen och samtal utanför diskursen. Resultatet av undersökningen visar att de flesta eleverna har, trots att de har ringa eller ingen erfarenhet av att arbeta med natruvetenskapligt arbetssätt, ganska lätt att ta till sig uppgiften.

Järnets förekomst i grundvattnet i isälvsavlagringar i Dalarna : Bakgrundshalter och rörmaterialets inverkan vid grundvattenprovtagning

A study has been performed that investigates the variation of iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of iron in groundwater. Piper diagrams were used to study the relationship between the chemical composition of the groundwater and the content of iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.

Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp

At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

Guilty until proven? : Nanomaterial i konsumentprodukter som sociovetenskapligt dilemma.

Nano materials can today be found in a wide range of consumer products and the number of new products on the market is expected to inrease. In the shadow of hope for nano materilas potential in various applications, low awareness of its health and environmental risks is hiding. Furthermore, the knowledge about people´s risk perception of nano materials is limited. Parallel to the situation described above, the scholls meet the challenge of incrasing the scientific literacy. To achieve this goal, skills in argumentation in science studies has been emphasized and the concept of socio-scientific issues has been emerged.

Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.
