The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

För hälsoarbetet är kosten en av de viktigaste faktorerna för att motverka övervikt ochfetma. Vanor skapas redan i tidig ålder, vilket gör det väsentligt med hälsofrämjandearbete riktat mot unga individer för att på lång sikt gynna folkhälsan. Vidbeteendeförändring är det centralt att se till individers motivation då det påverkarbeteendets utfall. Self-determination Theory (SDT) är en beprövad teori som använtsinom ett flertal domäner för beteendeförändring och som visat sig användbar även ur etthälsoperspektiv. Av tidigare forskning inom SDT har få studier fokuserat på kost ochingen tidigare studie har specifikt applicerats på motivation till att äta grönsaker.

Aim: The aim of the study is to show how a Bildung-oriented biology teaching could be designed, along with providing classroom examples of such teaching. In this study, the term Bildung, is defined based on the German Didaktik tradition as competences for self-determination, constructive participation in society, and solidarity. Theory: The study is based om Englund?s thoughts of teaching as didactic choices that express different views of meaning, socialisation, method, and context. This is referred to as companion meanings. Additionally, the theoretical framework is influenced by Gadamer?s thoughts on understanding through dialogue and Klafki?s didactic analysis of educational content for Bildung-orientated approaches. Method: The empirical qualitative study is based on ten semi-structured interviews of biology teachers at Swedish Folkh?gskola.

Immune stimulating complex (iscom) matrix is a formulation that is used as anadjuvant within research. The capability of the iscom matrix to elicit an immuneresponse when not present together with an antigen has not been extensivelyinvestigated. One way to evaluate the status of the immune system is to measure theamount of cytokines that usually are produced by various cell types during an immuneresponse. The aim of the present study was to evaluate the early immune responses inporcine peripheral blood mononuclear cells (PBMC) after stimulation in vitro with theiscom matrix, AbISCO®-100. The immune response was evaluated by measuring themRNA expression for various cytokines, a chemokine receptor (CXCR4) andregulator of G-protein signaling (RGS16) in porcine PBMC after stimulation withAbISCO®-100 or other inducers like a lipopolysaccharide (LPS) and a CpGoligodeoxynucleotide (ODN 2216) used as controls.

The retrospective part of this study evaluates the susceptibility patterns of bacteria isolated from blood in critically ill foals in Sweden. The most commonly obtained bacteria were Actinobacillus spp. (38 %) and Escherichia coli (27 %). Trimethoprim-sulphonamide (TMS) had good efficacy against most gram negative bacteria with the exception of Klebsiella spp. Among 17 Escherichia coli isolates 94 % were susceptible to trimethoprim-sulphonamide whereas all 24 isolates of Actinobacillus spp.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

This essay is using theories about social norms, and wage determination to evaluate why there is a gender wage gap on the Swedish labour market. To identify the essence of the gender wage gap investigations on specific jobs where the genders are over-, under and equally represented has been made. Also a poll has been sent out to alumni business economics from School of Business, Economics and Law at the University of Gothenburg to evaluate their labor market from a gender wage gap perspective..

Habia Teknofluor AB makes parts of PTFE. With their process they reaches a pressure of 250bar at maximum. For their parts to improve they need to reach 400bar at least. We will give suggestions that can solve their problem. All our suggestions is described in the report with a conclusion.

Syfte och frågeställningar: Syftet med studien var att utifrån teoretiska antaganden om motivation inom Self-determination theory (SDT), undersöka elevers motivation till ämnet idrott och hälsa. Studien har följt en explorativ ansats utifrån frågeställningarna: i) Hur ser sambandet ut mellan typ av motivation hos eleverna för ämnet idrott och hälsa och deras självskattade grad av fysisk aktivitet utanför skoltiden? ii) Hur ser sambandet ut mellan elevernas typ av motivation till ämnet idrott och hälsa och deras uppskattning av föräldrarnas engagemang för ämnet idrott och hälsa? Metod: Deltagarna bestod av 147 gymnasieelever i årskurs ett och två, från en gymnasieskola söder om Stockholm. Eleverna besvarade en enkät i två delar. Den första delen innefattade items för att mäta typ av motivation.

Increased understanding of the mechanisms that operate in conjunction with the welding of metal surfaces may help to improve existing manufacturing processes, and to enable new products and combinations of materials. The purpose of the project has therefore been to acquire a deeper understanding of what is happening in the bond for steel and for the factors that form the basis for a bond to develop between metals in the production of laminates by pressing. The merge has been done by pressing and the surfaces after the experiments have been studied in detail in the scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and with interferenceprofilometry in Wyko, to provide a greater understanding of the mechanisms that influence the bonding in the interface between metals. The project was limited to contain the materials Docol 1000, HyTens 1200, Aluminum AA3003 and a commercial steel. The parameters varied in the experiments to study their influence closer are temperature, pressure, heat treatment and pretreatment. This has been implemented by pressing with varying temperature and pressure.

With this essay we want to enlighten the problems to match the brand image an enterprise has with their determination of prices. The purpose with this study is to examine how customers apprehend when cloth enterprises extend their brand in the same category. Further we want do identify how this kind of brand extension can affect the position on the market the enterprise has. Thereby we want from incumbent relevant theories develop factors which enterprises ought to take into consideration at the time of a brand extension in the same category..

AbstractIn this study, then collaboration agreement impact of the work on 11 and 19 § § MBL are studied. The employer and collective agreements bearing employee union are often involved in collaborative agreements to facilitate cooperation between them. Issues addressed to collaboration areoften questions related to employee participation. The purpose of this study is to investigate two local employers and related collective bearing employee unionsview of the cooperation agreement related to the MBL. The purpose leads to these questions:?How can co-operation agreements affect 11 and 19 § § MBL??What are theadvantages and disadvantages cooperation agreementscan lead to, regardingemployer disclosure and negotiation duty?To try to sort out these issues are interviews conducted to create a greater understanding of the work of the Cooperation Agreement between organizations and how it affects them.Results of the study suggest that collaboration agreement leads to simplifications in the work of the employer's information and bargaining duty.
