Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.

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.

Phosphorus is essential to all plants and is taken up from the soil as the ion H2PO4 - (and to some extent HPO42-). Plant availability depends on, among other factors, the soil pH. In order to provide for plant available phosphorus, it is applied as mineral fertilizers and farmyard manure. However, that causes phosphorus leaching from arable land to surrounding surface waters and lakes and contributes to the eutrofication. There are three types of soils in Sweden that are at higher risk of contributing to phosphorus leakage.

The study investigates questions and considerations emerging when stone in historic buildings needs to be replaced. The focus is on the surface treatment of stone in sandstone façades in pre-industrial buildings. That means buildings constructed by traditional methods and craftsmanship without the use of modern technology.The research issue originates from the extensive stonework that is planned for the façades of the Stockholm Palace. The project includes the replacement of large quantities of damaged stone to newly cut stone. This raises the questions about the use of modern and rational methods for surface treatment on the replacement stone.

Syftet med denna studie är att undersöka hur poliser inom den ingripande verksamheten hanterar de emotioner som uppstår i arbetet. Vidare avser studien även att undersöka vilken påverkan de emotionella aspekterna av arbetet får för poliserna.  Detta görs med hjälp av en kvalitativ metod i form av sex semistrukturerade intervjuer med poliser inom ett polisdistrikt. Studiens teoretiska ramverk består av begrepp inom emotionssociologin och socialpsykologin.Följande frågeställningar behandlas:Hur hanterar poliserna de känslor som uppstår i arbetet och hur kan detta karaktäriseras?Hur påverkar de emotionella aspekterna av arbetet poliserna, har det konsekvenser? Sammantaget visar resultatet att poliserna följer informella känsloregler som finns inom yrkesrollen och att dessa regler skiljer sig beroende på den situation poliserna befinner sig i. De hanterar även känslor i arbetet på ett sätt som kan beskrivas med Hochschilds begrepp surface acting och deep acting.

Introduction: This study aimed to investigate the validity and reliability of the 20m multistage shuttle run test (MST) for elite ice hockey players as a predictor of the maximal aerobic capacity and the how the result is affected by the players age, aerobic and anaerobic capacity, body composition and test surface. The purpose of this was to find out the potential of the 20-m shuttle run test as a measuringtool for the maximal aerobic capacity in frequent testing periods during the season. It is very interesting to be able to administer this easily because the competative phase of the season is very long compared to the pre-seasonal phase and earlier studies have shown that the aerobic capacity is being lowered during this competative phase of the season for elite icehockey players.Methods: 34 elite ice hockey players participated in this study (20.0±3.6 yrs, BMI 24.2±1.6 and VO2-max 58.0±4.8 ml O2?kg-1?min-1). During 3-5 days they underwent 2 MST tests (wood and rubber surface), treadmill running with VO2-max assessed with open-circuit technique, Wingate10% and FFM-assessment with underwater-technique.

This bachelor thesis discusses various difficulties with architectural paint research. The difficulties are exemplified through a case study ? a paint research on a furrowed string-course in the southern vault of the Royal Palace of Stockholm, which was carried out November ? March 2009-2010 on behalf of Statens Fastighetsverk. The paint research was made in order to receive information about the string-course and to get inspiration for a renewed color scheme on it. The base material of the string-course is Gotlandic sandstone and the surface of it is furrowed.

To be a farmer and have suckler cows is a difficult combination especially considering the economy. Because of the increased feed costs, the margins have become tighter. The meat price from beef cattle has increased a little when this text is written (spring, 2008), but not so much that it covers the cost for feed etc. I have a small suckler cow production on approximately 30 cows and 2 bulls plus followers as a part-time business. The herd is tied in the old dairy stable built in the late seventies.

Syndecan-1 is a cell surface proteoglycan which participates in cell adhesion, differentiation, motility, morphogenesis and intracellular signaling. The two glycosaminoglycans heparan sulfate and chondroitin sulfate are covalently attached to the ectodomain of syndecan-1 via a tetra saccharide linkage sequence. However, the ectodomain can be modified having only one or neither of the glycosaminglycans attached. The glycosaminoglycans are capable of binding ligands such as fibroblast growth factors (FGFs) and support activation of receptors. The ectodomain is proteolytically cleaved from the cell surface by metalloproteinases in a process known as shedding.

The aim of this study is to find information about what to do when riding arena footings are worn-out. Especially, the surface layer of riding arena footings is very interesting because of its importance of giving grip in every step for the horse, as well as shock ab-sorption. Generally, surface layers are containing several different parts in order to achieve desirable properties. These different parts can consist of organic material or in-organic material (mostly gravel). Gravel and many other materials in the top-layer are environmental friendly, and therefore, easy to get rid of.

Mellan år 1987 och 2000 fanns ett beväpnat helikopterförband inom arméflyget. Dessa två pansarvärnshelikopterkompanier användes för att bekämpa stridsfordon. Efter nedläggningen har Sverige inte haft en helikopter med beväpning för annat än egenskydd.Uppsatsen syftar till att utifrån William S. Linds teori om manöverkrigföring utvärdera om pansarvärnshelikopterkompanierna framgångsrikt bidrog till att besegra motståndaren.Det framkommer att pansarvärnshelikopterkompaniernas taktik väl stämmer överrens med Linds teori vilket pekar på att bestyckade helikoptrar är ett mycket användbart instrument inom manöverkrigföringen.  .
