Kvaliteten hos charkprodukter efter borttagandet av namnskydd, samt införandet av EU:s köttdefinition
Until the 1st of January 2003 there were thirteen processed meat products provided with name protection in Sweden. These products had to contain a certain amount of meat and/or a certain amount of fat to be allowed to carry a recognized name. Among these thirteen products, one could find, for example, meat balls (köttbullar), liver pâté (leverpastej), and Falun sausage (Falukorv). While imports of these products started to increase, the system with name protection lost its ability to guarantee a certain quality for all products sold in Sweden and the legislation was removed on December 31st 2002. At the same time, a common definition of meat was adopted in the European Union.

Injektion till katt ? injektionsassocierad smärta samt injektioner i praktiken
Intramuscular injections to cats can generate strong reactions in some individuals while reactions of the same extent, according to the author, not always are recognized when using the subcutaneous route. The reactions are probably caused by fear, stress and/or pain.
When the injection can generate pain one has to take that into account, which can be a limitation in treatment. It is well known that injections generate pain, but knowledge about the cause and processes of the injection-associated pain is limited. This is mainly due to the difficulty in finding objects to study pain on, high cost of use of laboratory animals and difficulty to obtain objective measurements. Although there is evidence that there may be a local muscle injury by intramuscular injection, it is not always that the extent of damage is related to the pain experienced.
Facts about the causes of injection-associated pain have been studied in a literature review.
Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen
Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

Olof Palme och löntagarfonder : En studie om rörelsesocialism och statssocialism i den svenska arbetarrörelsen
The purpose of this essay is to examine wage-earners' investment funds from the ideological point of view. Were they in any way an integrated part of social democratical democratic socialism and reformism? I emphasize Olof Palme´s ideological idea of democratic socialism and reformism, and how he handled the issue. How did the question of these funds correspondent with the basic ideological points of view, and what was the standpoint of Palme in this issue.My method is built upon a deep study and analyses of SAP board of party and the standing committees protocol in the light of Olof Palme´s and SAP's ideology. I even use information from literature, inquiries and dissertations.
Utveckling och konstruktion av växellåda för elektroniskt styrda ställdon
The task of constructing a transmission has been provided to us by Digital Engineering, which is a company located in Hovmantorp. After meeting with Digital Engineering we started immediately with the brainstorming to find different ideas with pen and paper. After having presented a number of concepts for the company, we had finally chosen a winner. For the gearbox to be able to work in a good way the tension must never exceed the strain limit of the material. A prototype of the gearbox was produced by TKB Modell.
"Det här är inte ett hospice" : Konstruktioner av död och döende på en avdelning för palliativ vård
The study aims to analyze conceptions of death and dying at a clinic for palliative care, using a constructivist perspective and a discourse analytical approach. The empirical material consists of interviews with staff members, documents and photographs of the environment, taking both space and materiality into account. I conclude that the studied practice is mainly characterized by a tension between a caring discourse and a medical discourse..
Bestämning av kroppssammansättning hos överviktiga och obesa ammande kvinnor. Validering av bioelektrisk impedans mot röntgenabsorption.
Introduction: Pregnancy, obesity, aging and certain diseases are examples of conditions thataffect the body, its constitution and composition. Simpler methods to estimate bodycomposition are needed to complement more advanced traditional methods to better identifythe health status without sacrificing accuracy and precision.Objective: To validate the results of body composition from bioelectrical impedancespectroscopy (BIS) against results from the study reference method, dual energy X-rayabsorption (DXA), in overweight and obese lactating women after childbirth.Method: The design of the LEVA-study (Lifestyle for Effective Weight loss during lactation)consisted both intervention and longitudinal follow-up, which gave the opportunity tovalidate the absolute values (accuracy) and the ability to detect changes (precision). Themean difference between methods was tested statistically by paired t-test. Bland-Altman plotsused to examine the degree of agreement between BIS and DXA, but also distribution andany systematic differences. Association between methods was measured by using Pearson´scorrelation coefficient.Results: Between BIS and DXA, absolute measurements of the variables fat-free mass (FFM)and fat mass (FM) showed a statistically significant difference (p < 0.001).
