The system would also attract new inhabitants and businesses to the municipality.This report deals with various issues that podcar stations may face. Also, suggestions for possible track laying at the stations and station design are presented. Two areas are investigated. Eds allé which is a neighborhood that is planned for housing and where the station may be planned into the cityscape from the start.

The purpose of this thesis is to examine the relationship between the elderly at a retirement home and their professional caretakers with focus on the perspective of the elderly. Chosen method, a qualitative interview analysis has been conducted to describe how the relationship affects the elderly in their everyday lives. The total amount of interviews were four. The relationship between the elderly and their professional caretakers has rarely been examined in previous research from an elder?s perspective.The results indicate that the elderly often are satisfied with the way the professional caretakers treat them.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

Over 90% of forestry work is carried out today by contractors, thereforeclear agreements between the client and the contractor it is of utmostimportance. Contract Packages for work within the forest sector (APSE) is acollection contract templates that the industry jointly developed for thispurpose. The purpose of this thesis is to examine how forest contractors doto keep themselves updated of the current laws and government regulations,which channels are available to accomplish this and what possible obstaclesmay occur. 20 interviews were conducted with contractors engaged inlogging. The results show, among other things, the availability of and whichchannels most contractors use out of which aggravating circumstances existand how strong they are perceived and what is expected of the client in thisregard..

Storm water causes a number of problems in our country, particularly in city environment with its surfaces of non-absorbing ground materials. At heavy rain falls there are floods due to lack of capacity in the drain system when meeting heavy water masses over a short time. When the drain system is overloaded huge water masses reach the recipient untreated and there causing disturbances in the aquatic ecosystem. Due to emissions from mainly traffic, industries and other human activities the storm water is polluted. Earlier the problem used to be solved technically, by increasing the capacity of the tubes and by construction of reservoirs to delay the floods peaks.

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.

The degree project was made forZetterbergs Industri AB. The company is market leading in Europe in the heavyvehicle industry, designing and building body systems for trucks.In their line of products is the hook lift called Livab, a flexible and uniqueproduct. The hook lift is often demanded by customers because its special ability tobe able to operate in situations with low roof clearance. The main operation principleof the hook lift can be described as a truck stand, laid down.There are two main versions of the hook lift Livab, AL 26 and AL 32. These are ofdifferent load capacity, 17 and 25 metric tons of gross weight respectively.

To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.

Thoroughbred racehorses have suffered from exercise-induced haemorrhage for over 300 years. Almost all competing horses develop exercise-induced pulmonary haemorrhage (EIPH) at some point but most horses don?t suffer from reduced competing capacity due to the disease. The cause of the exercise-induced haemorrhage is unknown. The most believed theory today is that EIPH is induced by pulmonary stress failure caused by pressure over 100 mmHg in the pulmonary arteries during exercise.

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.

The aim of this thesis is to examine the institutional effectiveness of the environmental institutions Helcom and the Mediterranean regime, by using Haas, Levy and Keohane's "the three Cs"; governmental concern, contractual environment, political and administrative capacity. The method used is a comparative analysis.This study takes into consideration the specific structural and economic factors that are prevailing in each region where the environmental regime operates. This study also takes into account the influence of the European Union as a factor that affects the environmental progress.By focusing the study on the line of conduct concerning hazardous substances by respectively regime this study shows that the institutional effectiveness is fulfilled in neither Helcom nor the Mediterranean Regime, although Helcom has been more successful. The lack of state capacity is the most restraining factor for both developing countries and countries in the transition towards being developed, to achieve a good environmental status of the sea. This study also shows that the European Union sometimes has a greater impact on the environmental progress in states, rather than the environmental regime in countries that were/are aspiring members, thus showing the ineffectiveness of the regime..
