Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern
Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.
Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet
There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes.
District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption
Research), which has focused on climate adaption in the Nordic countries.
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.
Förbättrad kommunikation kan ge bättre resultat på medarbetarenkäter
En chef använder olika färdigheter i sin vardag t ex kommunikation,relationsskapande och beslutsfattande. Likväl som chefen agerar med olikaledarstilar utifrån kontexten och medarbetarna. Kvaliteten på chefensfärdigheter och agerande kan bedömas i en medarbetarenkät därmedarbetaren även bedömer sitt och gruppens välbefinnande. Enmedarbetarenkät ska vara ett stöd för chefen att utveckla sitt ledarskap ochsin verksamhet. Denna uppsats analyserar de tio bästa och de tio sämstaenheterna från en medarbetarenkät i ett landsting.
Ett kvalitativt arbete på väg : - En kvalitativ undersökning för att öka kunskapen gällande systematiskt arbetsmiljöarbete inom en organisation som arbetar med vägservice.

The study adds weight to the relationship between the purchaser of the work and the organization as a prime contractor due to the compexity of the organization.
Vikten av ett välskött arbetsklimat: En kvantitativ studie av arbetsklimatets påverkan på ekonomiskt resultat
The well-being of employees has become a key concept in the rhetoric of the company boards and business literature of today. There is however not much statistic evidence of a connection between economic results and the perceived working climate. This thesis sets out to investigate whether there is a positive correlation between economic results and working climate on a work group level. It also aims to study which specific working climate factors influence the results. In order to meet its purpose this thesis analyzes employee satisfaction questionnaire data and economic results from more than 300 work groups.
Yrkeskulturen i hotell och restaurangbranschen.En fara för lärlingar och elever? :
English abstract The culture of hotel and restaurant work.Dangerous for apprentices and students?The study is based on a survey targeting 50 teachers at chef schools with good geographic distribution of 9 schools. Teachers answer questions on bullying and sexual harassment in the hotel and restaurant sector, and students practice shock in the meeting with the industry. Students face a hard and tough environment where it is expected that it will suffer a great deal of harassment and degrading treatment as part of a tradition. There seems to be a general but erroneous belief that the professional climate has improved.
Gruppens betydelse för inlärning
In today?s individualistic society, I experience a need to bring forward the importance of collaboration. From a sociocultural perspective, I have chosen to highlight the positive and negative aspects of collaborative learning, with the intention of illustrating the effects for the individual learning and development. I have therefore made an interview with an educationalist, who?s been a teacher all her grown up life, with the intent of illustrating her thoughts on collaborative learning.

Att finna den positiva avvikelsen : En fallstudie av en väl fungerande arbetsplats
AbstractDuring recent years the climate in recruiting new personnel has hardened as a result of high levels of employment and increasing competition in labour market. In order to resolve this problem, organisations have to adapt new strategies to attract and meet the demands of potential employees who have the required competence to meet job requirements.The aim of this study has been to examine a well functioning work place in order to elucidate explicit examples of what employees consider positive, and what can be ascertained as positive deviations. Narratives emanating from the unit manager and personnel illustrate their views on the positive influences found in their working place. Another ambition is to increase awareness and understanding about the factors that promote satisfaction in the workplace and positive deviation; and to utilise this knowledge.Traditional research on organisations has frequently focused on problems. The theoretical point of departure of this study is based on Positive Organizational Scholarship, abbreviated as POS.
Klimatanpassning kring Vänern : om ansvar och problem med att minska risken för översvämningar
Generellt går det att hantera klimatförändringar på två sätt. Dels genom att minska utsläppen av växthusgaser och dels genom att anpassa sig till de klimatförändringar som kommer. I denna uppsats kommer jag att fokusera på klimatanpassning. Ett av de områdena i Sverige som beräknas drabbas värst är runt Vänern, framförallt då sannolikheten för översvämningar väntas öka på grund av klimatförändringarna. Syftet är att ta reda på vilka problem det finns med att genom klimatanpassning minska risken vid översvämningar kring Vänern, samt undersöka vem som har ansvaret att lösa dessa problem.
