Avfallsdirektivets påverkan på efterbehandling av förorenad mark
The purpose of this report is to increase the awareness about the problem that occur when the waste hierarchy is applied to management of contaminated land. The work with remediation of contaminated land in Sweden is part of the efforts towards reaching the national environmental objectives. Therefore a subsidiary aim is to analyze how this influences the prospects of reaching the objectives. The work consists of two parts; a case study and a comparative literature study that focus on England, the Netherlands and Sweden. The case study is intended to provide a practical perspective through a comparison of the climate impact from two methods.
Energianvändning i serverhallar: energiflöden och kylning
This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.
Value Stream Mapping över brevets väg i Uppsamlingsprocessen : En fallstudie på Postens brevterminal i Alvesta
Background: The demand for sending letters, in the traditional aspect, has decreased because of electronic sources which have replaced a big part of letter communication. The Postal Service constantly strives for lowering costs and due to the changeable demand, a greater awareness is required regarding recourses and their usage. The previously mentioned measures in combination with commonly occurring quality issues during the collective process at the letter terminal in Alvesta would be improved by applying a lean-perspective to the process. A first step towards saving of time is to apply the ?value stream mapping?-method on the collective process for small and large letters.Purpose: To map the process of collection for small and large letters to be able to identify waste of recourses and furthermore give suggestions on how the Postal Service would be able to reduce the waste of recourses identified.
Ämnestransport med grundvatten i hydrogeologiska typmiljöer
Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.
Vitvarueffektivisering med hjälp av värmelagring : Simuleringsstudie kring energiförsörjning av vitvaror med hjälp av värmepump & ackumulatortank
The constant need of energy is something that affects us all no matter our current situation. Whether we are driving our car to work, taking the elevator or using the oven to cook dinner we end up relying on energy. Our whole society is continuously striving to achieve a higher grade of efficiency and the process of supplying ourselves with energy is no exception. The importance of appliances in our everyday life cannot be exaggerated and thus the importance of their high efficiency.Efficiency is already a keyword in the appliance industry with labels, stars and numbers helping us choosing the most suitable option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source.
En lärande organisation? - Kompetensutveckling inom en Polismyndighet
This essey discuss competence development for the employees in a unit of the Swedish police authorities. The purpose with this survey has been to show an understanding for how this unit within the Swedish police authorities works with competence development and what kind of competence investments they carry out and also why competence development is important in their organisation. To answer the purpose of the survey and the questions a qualitative method has been used remaining interviews with five involved respondents working in the investigated unit. The result shows that needs for competence development are made clear during meeting for personal development and during the local educational council inventories. Competence development for the employees is prioritated for the policemen comparing to the civil employees on account of that the policemen have a demanding work and they have to develop their work all the time because of the resisting circumstances.
Materialavfall som resurs : En studie av hur man samarbetar i en region fo?r ha?llbar utveckling
The concept of sustainable development has been pervasive in recent years and many organizations choose to implement sustainability and adapt their activities accordingly. The purpose of this study have been to explore how a collaboration on the use of waste materials may look to analyze what influences cooperation. A case study has been carried out examining a Swedish state regional project aimed at creating partnerships between actors and utilizing textile waste with the help of design. The study was conducted using qualitative methods and the collection of data has been done through interviews and by examining documents. The results show that there are seven key factors that affect cooperation: expectations, commitment, internal communication, a strong non-profit actor, individual treatment, personal networks and the diversity of actors.
Nerver i karpala flexorretinaklet på häst
The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.

PLASTHANTERINGEN I SVERIGE En kvalitativ studie om storstadskommunernas plasthantering utifr?n EU:s Plastdirektiv (EU) 2019/904
The aim of this essay is to examine the handling of plastic waste on a local level in the three
municipalities of Gothenburg, Malm? and Stockholm. This is achieved with the help of
guidance within the theory of Multi-level Governance. By applying the EU directive
2019/904, about disposable plastic, and examining the global plastic problem, the efforts to
promote sustainable use, and recycling of plastic, is analyzed. The method involves a
qualitative content analysis, where the 2022 waste plans of the three municipalities, ?Sveriges
handlingsplan f?r plast? by the Government Office, and the 2019/904 EU directive constitutes
the base of the study.
Den moderna flerenhetsfranchisetagaren: En studie i utformandet av kontrollsystem hos växande franchisetagare
Franchise theorists have to a large extent failed to keep up with the actual development in global franchise chains. The recent emergence of fast growing multi-unit-franchisees has fundamentally been ignored, and it has been claimed that the new phenomenon can be regarded as a mere replication of the franchisors? structure and control system into sub hierarchies. This study however, suggests that the reality is more complex. Through conducting case studies of two Nordic multi-unit-franchisees, new theories are built explaining how and why control systems are designed the way they are.

MATSVINN FÖRSVINN - En kvantitativ studie om hur ett CSR-argument kan involvera konsumenten i kampen mot matsvinn i butik
Every year 67000 tons of food is wasted by Swedish retail stores. The waste implies financial losses for the retailer and it has a huge impact on the global environment. Reducing in-store food waste is thus a win-win situation for both retailers and society. The most effective way to reduce waste is primarily by optimizing the logistics of supply, but customers expect a store with a wide range of products and stuffed shelves. Thus there will always be products about to expire.
Fysikalisk modellering av klimat i entreprenadmaskin
This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.
