In this report the balconies? abutments for a property in Bo01-area in Malmö has been studied. The property which is called Vitruvius contains four build-ings where two of them have corbelling balconies with intermittent abutments. With intermittent abutment means that the 50 mm thermal bridge insulation that the balconies is equipped with, is broken regularly by a 300 mm concrete heel. The reinforcement bar that holds the balcony runs through this heel.

The application of the LSS law and how the public organization (Municipality of Hudiksvall) later had to reform their organization to fit the new demands is the foundation to this master's thesis. An internal evaluation was performed due to this reorganisation process within the social care department (LSS unit). The aim was to investigate and evaluate if the reorganization resulted in a better working environment and if the work load (distribution of work) became more evenly divided between the different unit managing directors. The primary empirical information to this master's thesis is collected from that evaluation report. The main aim of this master?s thesis is to answer if the organisational choice between specialised or de-specialised working tasks has an effect (experienced and measured) on the level of stress among the unit managing directors.

På dagens fönsterglasmarknad har produkter med samma funktioner och utseende fått olika namn. Detta är förvirrande och gör det svårt för en person som ska beställa fönsterglas att jämföra olika tillverkares produkter med varandra. Rapporten är tänkt som en översikt på de olika fönsterglasen som finns på marknaden idag och även på sådant som kan bli aktuellt i framtiden. Den berör också sådant som kan vara av värde att veta vid användning av fönsterglas. Målgruppen är alla som kan tänkas ha intresse i ämnet - alltifrån hobbybyggaren till fackmän i byggbranschen.

Intresset kring lågenergibyggnader blir allt större och så kallade passivhus, med god isolering, hög lufttäthet och värmeåtervinning, byggs i allt större utsträckning i Sverige och andra europeiska länder. Vissa frågetecken har dock uppkommit kring inomhusklimatet i husen och risken för både under- och övertemperaturer. En annan viktig aspekt är hur husens egenskaper påverkar värmelasterna och hur detta i sin tur påverkar energiförsörjningssystemet. I detta examensarbete undersöks dessa båda aspekter ? värmelastegenskaper och innetemperaturer ? i fyra likadana nybyggda flerbostadshus i Falkenberg.

The chow-chow breed is considered to have a low fertility and this report is an in depth study of the reproductive functions of this breed in Sweden. Only 53 % of the Chow-chow matings results in litters. Previous studies of other breeds in commercial kennels shows mating results around 85-90 %, but this has not been investigated in hobby kennels and most Chow-chows which are bred from in Sweden, are kept as family pets. Contrary to most other breeds, Chow-chows show a seasonal reproductive pattern and most litters are born in the autumn. The influence of the month of mating on pregnancy rate and litter size was found to be not significant, but can be considered a trend. Thirty-nine females with previous known fertility problems where studied. Some of them had reached puberty extremely early, at an age between 4-5 months, and many of the bitches showed great fluctuations in intervals between oestrus cycles. Some of the females showed abnormalities such as very short oestrus intervals of only 2-3 months, probably without ovulating.

Långtidsbehandling med ventilator utan tillräcklig befuktning kan torka ut en patients luftvägarmed olika komplikationer som följd. Målet för detta examensarbete var att utveckla en ny teknikför att befukta och värma inandningsgasen. Ett fungerande koncept och en prototyp som styrkerkonceptet skulle tas fram.Marknaden för befuktare studerades och de vanligast använda befuktningsmetoderna granskadesför att hitta svagheter som behövde åtgärdas. De två vanligaste befuktartyperna är HeatedHumidifier och Heat and Moisture Exchanger. Den främsta nackdelen med Heated Humidifiervar dess tendens att övermätta luften med kondensutfällning som följd, och med Heat andMoisture Exhanger att inte tillräckliga fukt- och temperaturnivåer nåddes.Därför togs en ny design fram med målet att kunna styra fukt och temperatur oberoende avvarandra.

Denna rapport bygger på den kommande solcellsfasaden på kvarteret Frodeparken i centrala Uppsala. Projektet genomförs genom ett partneringavtal mellan Skanska Sverige AB och Uppsalahem. Syftet med detta examensarbete var att skapa en underhållsplan samt en investeringskalkyl för projektet. En teknisk bakgrund för solcellsanläggningar har sammanställts för att förstå hur systemet fungerar. Underhållsplanen grundas på fakta från solcellsleverantören och uppgifter från referensobjekt. Det har visat sig att solcellsanläggningar kräver väldigt lite underhåll. För att få en bred syn på investeringen har ett antal simuleringar på investeringskalkylen genomförts.

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.

Lining techniques such as nap bonding and mist lining were developed in the late 20th century and have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced, which can be advantageous for more sensitive paintings. These lining techniques have been included in several studies where reversibility, minimal intervention and respect for the individual requirements and problems of each object have been the focus. The adaptability of the methods has been confirmed and to further explore the adaptability, this study consists of three simpler application techniques with the adhesive Lascaux 303 HV on mockups.

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.

SUMMARY Several studies have shown that weaning pigs are in great need of heat. The reason for this is mainly because the pigs are given very little feed just after weaning. Some of the pig producers of today have tried to get along with these problems by building some kind of hut for the pigs. Some of these pig houses have been included in this study.The study has shown shortcoming functions for the pig cottage. The expected heat increase has not occurred.

This thesis has been carried out on behalf of IV Produkt AB and intends to set an average ratio of thermal energy losses in apartment buildings that were built during the 1960-1990. This shall be derived by analyzing the total district energy consumption that has been divided into three parts: heat energy losses (the actual heating requirements), the heating of domestic hot water and heating energy consumption for the controlled ventilation.Three different residential areas that were built during the years 1962-1966 and one that was built in 1993 has been analyzed. All residential areas are located in Växjö urban and contains between four and six apartment buildings.The analyzed objects have a mechanical exhaust ventilation systems and district heating as the heating method. No own laboratory work or experiments have been done in this thesis, the calculations have been done on the basis of parameters from VEAB, interviews with property managers, and literature studies. By calculations, we have got a result that is reported in Chapter 6.

Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.
