Prefabricerade passivhusväggar

Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

The role of FGFs in the elicitation of different cellular responses

Fibroblast growth factors are signaling peptides that controls important cellular processes such as proliferation, differentiation, migration, adhesion and survival. Through binding to different types of receptors on the cell surface, these peptides can have different effect on the target cell. Which effect that is achieved depends on many factors. Thus, each of the 24 known FGFs different biological responses. The FGF receptors (FGFR 1-4) initiates different intracellular pathways which in turn leads to different biological responses.

Automatisk plastlisthanterare

Today a lot of goods is transported on wood pallets because it?s practical and enabels a fast way to load cargo. The drawbacks with pallets are that they weight a lot, are big and are relatively expensive. Therefore IKEA has developed plastic lists that can replace the europallet in some applications. In this examwork an automatic handling equipment for plastic lists are design from a requirement specification to a finished machine.

Procedurellt genererade provinskartor för strategispel : En jämförelse mellan Voronoidiagram och Cellular Automata

Procedurell generering är ett område som vuxit mycket på de senaste åren men som också är ett gammalt område. Kända koncept inom detta område är kart- och terränggenerering. Koncepten används för att skapa både verklighetstrolig terräng och för att skapa spelkartor för spelaren att utforska.Detta arbete använder sig av procedurell generering för att undersöka skillnaden mellan två kända metoder; Voronoidiagram och Cellular Automata vid skapandet av en provinskarta. Tre kartor från varje metod evalueras genom att importeras i spelet Crusader Kings 2 och sedan spelas med hjälp av spelets artificiella intelligens. Kartorna evalueras genom att titta på tre olika faktorer för hur intressant kartan är och prestandan för att skapa en karta.

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.

Kundlojalitet : En studie om hur man skapar lojala kunder inom mobiloperatörsbranschen

The cellular market is today suffering from great customer dissatisfaction. Simultaneously, the services offered by the different cellular providers are very homogenous, causing strict competition where various price strategies have been the main mean of battle. From a business perspective, implementing pricing strategies, to keep up with increased network investments, is a short term solution.In a market characterized by lacking customer satisfaction and harsh competition, research has shown the importance of highlighting customer relations in marketing. This type of marketing, which one could refer to as relationship marketing, is considered an efficient, economic, and strategic method of showing the importance of customer loyalty. To get insight in the relationship between the customers and the cellular providers, as well as to show the importance of relationship marketing, this study has used qualitative interviews to find what develops strong customer loyalty.The results showed that increased customer loyalty is achieved when an emotional bond is created.

EN TOTALKOSTNADSJÄMFÖRELSE MELLAN CELL-, SKUM- OCH LECA-BETONG

This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.

Grundläggning med cellglas : En studie av byggtid och lönsamhet

This report describes a new foundation method and compares it with a traditional founding of concrete. This new method is called the Koljern technique and uses cellular glass which is called Foamglas. The Foamglas is compounded to founding elements by lightweight steel beams. Foamglas is an insulation material with high compressive strength, and is rot, insect, vermin and acid proof. The cellular glass is also fire proof and watertight, which makes it a very good construction material.The report contains a study of a number of cases for which the Koljern technique is compared with a foundation of concrete.

Micro plastics in the oceans and their effect on the marine fauna

Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.

Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor

In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.

Täckning av plansilo :

With the increasing costs in concentrate the importance in producing ensilage with a high quality is becoming more and more important. To succeed with this goal it is of importance not only to harvest in the right period, but also to be able to store the ensilage without a decrease in quality and nutrional values. To maintain a good ensilage the covering of the ensilage must be carefully made. An unsuccessful covering causes mould to grow in the ensilage, which both increases the work load and also increases the amount of feed which is wasted. A bigger amount of spoiled feed also increases the risk of feeding spoiled feed to the cattle.

Metallersättning inom byggbranschen

In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.
