On ocean beds around the world sinking particles of residual biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth?s past climate, information that can be used to predict future climate change and to estimate natural vs. human causes of today?s global warming.The Institute of Geosciences at Stockholm University studies sediment cores that have been acquired with an apparatus called piston corer.

Introduktion: Suicidala patienter är en patientgrupp som väckte känslomässigt engagemang hos vårdpersonalen.  För att kedjan av vårdinsatser mellan den somatiska och psykiatriska vården skulle fungera optimalt behövdes ett väl utvecklat samarbete. Syfte: Syftet med studien är att belysa vårdpersonalens upplevelse av att vårda en patient som utfört en suicidal handling samt samarbetet mellan psykiatrisk och intensivvårdsavdelning vid vård av dessa patienter. Metod: Studien gjordes med en kvalitativ metod med intervjuer i fem fokusgrupper där resultatet tolkades med hjälp av en manifest innehållsanalys. Resultat: Studien visade att vårdpersonalen upplevde den suicidala patienten som en komplext och resurskrävande patientgrupp. Resultatet visade även att man önskade ett mer utarbetat samarbete runt dessa patienter mellan intensivvården och psykiatrin.

The Open Access (OA) movement came to be as a reaction against the enclosure of information resources, facilitated by new distribution technologies. The purpose of the OA movement is to make research results freely available. The aim of this master´s thesis is to increase the understanding of how libraries outside of the academic sphere and within research institutes relates to OA. As a theoretical framework I created two different ideologies, the OA ideology and the nonsharing ideology. I also conducted six interviews with librarians.

The functionalism started in southern Europe after world war one and got its breakthrough in Sweden with the Stockholm Exhibition in 1930. Poverty caused many people living in overcrowded conditions which the functionalists wanted to change by using less expensive materials and giving healthier living conditions to the people. The industrialization brought new materials and working methods which made this possible. The Swedish functional style is recognised by its light plaster facing and nearly horizontal roofs. Also the garden design of that time was influenced by the functionalistic ideas. The garden was now introduced as a pleasure garden for not only the rich but for everyone.

Oron för miljön och hållbarhet har ökat dramatiskt under de senaste åren. Men problem och frågor som rör kommunikation av hållbarhetsarbetet har förblivit obesvarade. Kritik har gjorts att hållbarhetsredovisning är vagt kopplat till verksamheten och att det inte finns ett samband mellan hållbarhetsredovisning och redovisningssystem. Som ett resultat av detta har en ny form av hållbarhetsrapporter utformats. Det underliggande syftet med den nya rapporteringsstrukturen är att integrera rapporteringen i företagens årsredovisning.Studien har ett jämförande perspektiv och kommer att fokusera på fyra branschledande företag.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

Denna uppsats behandlar ett populärt sätt att bruka historia på. Den riktar sig mot samlare av historiska ting och hur de aktiverar en historiekultur. Uppsatsen belyser interaktionen mellan människa och ting. Med utgångspunkt i ett interaktionistiskt perspektiv påvisar resultatet att en människa - ting - människa relation kan utvecklas i takt med att samlandet gör det. Samlandet följer också ett visst mönster och är av en processartad form som rör sig från ett naivt och lekfullt samlande mot en allt större systematik allteftersom samlandet utvecklas.

This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.

There are several different methods of assessment of functional communication in individuals with aphasia. However, these are not very established in Sweden. A number of assessment methods are not translated and adapted to Swedish. The views about what functional communication means are scattered. The purpose of this study was to, with the help of a questionnaire survey, identify how Swedish speech and language therapists assess functional communication, to what extent and what they want that an assessment method should contain to be clinically useful.The study involved 54 clinically active speech and language therapists in the area of aphasia.

The main purpose of this thesis was to examine the collection management at five different hospital libraries´ children and youth?s section to discern different roles of the collections. We made qualitative interviews with five hospital librarians. The purpose was also to see how the collection development affected the different roles of the collections. We used two theories.

Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.

The purpose with this work that is the basis for this thesis was to help Nattavaara Economical association to develop a program for handling invoices, customer information, and storage. The program and this thesis have been done in cooperation with the economical association in Nattavaara. Some of the demands on the program are that it shall handle customer information, storage status, invoices and diesel consumption. The program must be able to printout invoices, reminders, delivery notes, a customer list and a storage list. All information will be stored in a database.

For an outdoor environment to function optimally as a playarea requires that it is flexible, that is, contains places and elements that give room for the imagination and for own interpetretations, and also that the children in some way can influence and change their surroundings. It is also important to have variety, both in the sense that the playground has a unique character that distinguishes it from other places, and that it allows many different games and activities. There should for example be room for both wild games of running and moving around where many children can participate, and calm corners to withdraw to for rest or quiet play. A good playground should surprise, challenge and encourage children to discover their surroundings. One way to achive this is to use plants and materials from nature, whose irregular forms and structures can become interesting elements to explore. Vegetation also gives sence-experiences of various kinds, materials like twigs and leafs to play with and a place to play house.

Quality assurance for Scania engine componentsScania engines have become one of the world?s most renowned corporations in themanufacturing of engines.
