Jämförelse av vertikala accelerationer av järnvägsbroar för höghastighetståg.

Under de senaste decennierna parallellt med klimatdiskussionen har det vuxit fram ett stort intresse för höghastighetståg och en förbättrad infrastruktur i Sverige. I delar av Europa men speciellt i Kina och Japan har utvecklingen av höghastighetståg fått ett enormt lyft. Ett problem vid höjda tåghastigheter är att broarna vid en kombination av låg massa och låg egenfrekvens riskerar att orsaka resonans och höga accelerationsnivåer vid passage.Ballastspår är namnet för det traditionella järnvägsspåret i Sverige. Ballastfria spår är motsatsen till ballastspår. Andra namn för ballastfria spår är Fixerat spår eller slab track.

Svensk- eller mångkultur? : En studie av hur lärare förhåller sig till läroplanens begrepp; kulturell mångfald, svensk kultur & gemensamt kulturarv

This essay is a study of how teachers in social studies relate to three central curriculum concepts; cultural diversity, swedish culture and common cultural heritage.Through unstructured interviews, I have taken part of two practicing school teachers interpretations and understandings of the concepts and their practical approach for teaching about identity. An area mentioned in the core content of the courses Social studies 1a1 and Social Studies 1b.The conclusion of my study is that teachers interpret the key concepts in a transparent manner. It is believed that the main task is to problematize the concepts rather than define them. In contrast to this, the practical teaching is largely based on normative values. An open discussion and a normative practice can be said to balance right on the border between the schools values ??and the demands of the curriculum on transposition of the current culture..

Samhället uppmuntrar individer att se över sina hälsovanor för att öka välbefinnandet. Syftet var att undersöka om val av fysisk aktivitet hade effekt på den generella hälsan i ökat subjektivt välbefinnande samt om det fanns könsskillnader i dessa. Sextio män och kvinnor mellan 25-50 år valdes slumpmässigt ut från träningsanläggningar för att besvara the 12-item General Health Questionnaire (GHQ-12) samt Swedish Core Affect Scale (SCAS). Resultatet visade på signifikant ökning av välbefinnande efter fysisk aktivitet samt inga könsskillnader. Dock fanns en signifikant interaktionseffekt mellan kön och fysisk aktivitet, de män som promenerade och kvinnor som konditionstränade hade högst välbefinnande och generell hälsa.

Ekologisk gestaltning : en utvärdering av hur landskapsarkitektur påverkas av ett ekologiskt förhållningssätt

This paper examines and compares several different sites in Sweden in addition to one in Mexico regarding whether the ecological requirements theses sites have had during planning and construction has affected the design in any way. Is it possible that, for different reasons, one thinks ?like nature? when one thinks of ecology and, if true, how does this reflect on the spatial and structural design? This paper tries to identify if some sort of general design expression is used in projects with requirements on ecological sustainability. In total, five projects have been compared in different areas such as choice of materials and their composition. These projects have an ecologically sustainable processing of water in common, although most also have ecological consideration in other areas as well.

This thesis studies the concept of balance in the management control systems (MCS) of a small Swedish company within the IT-sector. The aim is to evaluate the importance of balance and dynamics in MCS and investigate which factors affect them. The frameworks used are Simons (1994) four levers of control, and the five-factor model for balance and dynamics by Mundy (2010). The small IT company - the object of the case study - has grown extensively in the last years and needs to develop more formal MCS without losing efficiency and creativity in their fast-moving industry. The case study reveals that balancing MCS is important also in smaller companies with less formal MCS.
