Water connects heaven and earth. Water is the most obvious element of nature. To move in water is for me more than cooling of on a hot summer?s day. It is about freedom and the feeling of being above the state of things.

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.

This report consists of  an anlysis of the imapct of a dam failure at Tjärnviksdalen in Ragunda, Sweden. The analysis is conducted using the EU model for environmental impact assessments, as well as a group interview. The presentation of the results in the form of a map  where the water level has been raised to the level that the County Board  of Jämtland considers to be possible in case of a dam failure.The result of this work is a detailed analysis of the consequenses that a dam failure would cause, the result consider everything from the direct consequences of the water column to an analysis of the chemical changes that the water would undergo.Parts of the analysis have shown that the purification centre and the old deposits will have the biggest impact on Hammarstrand. Both the purification centre and the deposits will realise chemicals to its nearest environment and because of the flooded purification centre the city will not have the ability to clean the water. .

More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).

This Diploma work investigates internal air ventilated crawl-space in respect to construction and damp. The Diploma work assumes from a general description of crawl-space and general dump problems in ground construction. An internal air ventilated crawl-space is a construction where you take the ventilation air from the building and bring it down to the crawl-space and lets the air circulate before it passes through a retaining aggregate on the way out from the crawl-space. In this matter you get a worm space under the building and a lot less dump problems in form of · Ground damp · Build damp The ground dump reduces through draining around the building, different layer of gravel between the ground and the building and ventilation of the crawl- space. The build dump reduces through ventilation of the crawl-space as fast as possible.

Animal art is one of the more mystical aspects of Scandinavian Iron Age culture. It has foremost been regarded in the light of art and style history. Interpretation has also ? mainly from the 1990s and onwards ? been made through iconographic analysis. But the problem here is that iconography requires textual analogy, something that the Scandinavian Iron Age lacks.The purpose of this paper is to lift some of the ?mystical fog? that engulfs the scandinavian animal art, by developing a method for interpretation of pre-historic images that evades the flaws in the iconographic method.

By using pollen analysis and 14C-dating, the history of vegetation and land use at the old shieling place (Sw: fäbodställe) Öjingsvallen in Ängersjö parish, central Sweden, was studied. The aim of the study was to answer the following questions: 1) When was Öjingsvallen established as a shieling place? 2) What was the land use at Öjingsvallen? 3) Was the use of Öjingsvallen as a shieling place affected by the agricultural crisis in the 14th and 15th centuries? 4) Is there any relation between the establishment and land use of Öjingsvallen as a shieling place and the historically known increase in the number of shieling sites known to have taken place in the 16th and 17th centuries? 5) Was the use of Öjingsvallen as a shieling place affected by the iron production in the area? According to the study, Öjingsvallen was probably established as a shieling place during the period A.D. 300-700. The main land use at this time was forest grazing.

Alnarp?s Healing Garden is a place for rehabilitation as well as an ongoing multidisciplinary scientific research experiment. The garden is built on research results from the disciplines of Landscape architecture, Environmental Psychology and Garden Therapy. In the garden, people diagnosed with burnout syndromes are being rehabilitated. The participants need safe and calm environments which activate their bodies self healing systems. Theories show that water as an element, per se, increases the observer?s preference for an environment.

Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Coconut water as a rehydration fluid. - Can coconut water be recommended as a better choice than water or sports drink after moderately intense training?Author: My Green, Joakim LundSupervisor: Henriette PhilipsonExaminer: Frode SlindeProgram: Dietician study program, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 26th, 2014Background: Already in the 1960s an alternative to water as a rehydration fluid occurred, the so-called sports drink. Coconut water has in recent years been claimed as the "natural sports drink" in media. Coconut water is sold in shops and fitness centers around the world and has established itself as an alternative to water and sports drink in terms of rehydration after a workout.Objective: To investigate whether there is scientific evidence to recommend coconut water as a rehydration drink after moderately intense exercise ahead of water or sports drink.Search strategy: The search for articles in this systematic review was performed in the databases PubMed, Scopus, Cochrane and GUPEA.

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

What is located on the bottom in the water outside of Birka? Remains of a water palisade or jetties and other constructions.Birka a Viking Age town that existed between AD 750 and 975 was located on the northwestern part of the small island of Björkö, in the Mälar archipelago of the Baltic Sea in Sweden. The Town was protected onshore by a hill fort and a town rampart. It is a widely spread assumption that Birka had a water palisade as a part of its defense. There are logs and other remnants on the bottom of the lake dating back to the Viking age.

Hunting ground graves were distinguished as a separate category during the 1930s.         There is however no clear definition of what a hunting ground grave is. They have been constructed over a large area over a long period of time (200 BC-1200 AD) and their morphology varies.This paper investigates how the archaeologists have discussed the hunting ground graves since they were distinguished as a separate category until today. It investigates what concepts that have been used to define and categorize the graves as a group. It also investigates if the choices of concepts are depending on a broader societal perspective.To find the answers to these questions two surveys have been done.

This paper deals with prehistoric charred organic material, interpreted as bread, found in graves and in the underlying settlement at Kalvshälla, Järfälla parish in Uppland. The aim was to categorize the organic material morphologically and with the help of Fourier transformed Infrared spectroscopy (FT-IR) to see whether it was bread or not. Material from 13 graves (dated to Late Roman Iron Age until Viking Age) and 3 finds from the settlement have been analysed. Differences were noted both in shape, porosity and structure. Some of the material has been interpreted as cereal based foodstuff instead of bread due to morphological discrepancies.

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.
