Salmonellos hos småfåglar har blivit ett ökande problem de senaste åren och studier har visat att det är den infektionssjukdom som orsakar flest dödsfall bland småfåglar. Salmonellos hos katter är ovanligt men utbrott har satts i samband med infektion hos småfåglar. Denna litteraturstudie tar upp vilka serotyper av Salmonella spp. som finns hos småfåglar respektive katter, hur bakterien sprids mellan småfåglar, och från småfåglar till katter samt vad som kännetecknar bakterien. Den serotyp som sprids mellan småfåglar och orsakar infektion är Salmonella Typhimurium och de fagtyper som dominerar är DT40 och DT56. S.

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

Man har förr trott att fågelpar inom många arter, t ex albatrosser och kungspingviner, är varandra trogna livet ut. Syftet med denna litteraturstudie är att ta reda på om det finns något vetenskapligt stöd för sexuell eller genetisk monogami hos någon fågelart. Uttrycket ?monogami? kan ha flera betydelser. Social monogami är att en individ lever i ett parförhållande med endast en partner åt gången. Sexuell monogami innebär att ett par kopulerar bara med varandra, och detta baseras på observationer.

To work with environments outdoors for people, animals and plants is the main topic for the landscapearchitect. On several occasions the work is about public places that is to be in relation with other parts of the town. It is about the activities and the life that take place. The physical environment and the interpretation of it gives possibilities or obstructions for people who moves around or spend time in it.Since public places, parks and places for movement are used in daily life they strongly effect the people who use the places. The concequences of this effect can be positive or negative experiences.A positive example is a passage over a brook on the way to school while a negative one is to be afraid while passing a tunnel when it is dark outside. Other examples of concequences are stress effect from traffic noice or calming environments with twitter of birds. The physical environment is also a part of the total interpretation of a town.

Försäljningen av smartphones och mobilapplikationer är något som de senaste åren har haft en stadig tillväxt och inget verkar minska expansionen, snarare tvärtom. Idag står smartphones för en tredjedel av all försäljning av mobiltelefoner och det laddas årligen ned miljarder av tillhörande mobilapplikationer till dessa mobiltelefoner. Att konsumenter väljer att ladda ned mobilapplikationer är tydligt, men vilka faktorer påverkar konsumentens val av mobilapplikationer?  Syftet med denna studie är att ur ett företagsperspektiv beskriva vilka faktorer som påverkar kvinnor och män i deras val vid nedladdning av mobilapplikationer till sin mobilenhet. Tidigare studier inom ämnet har inte vidrört eventuella samband/skillnader av påverkande faktorer mellan kvinnor och män vilket väckt ett intresse hos oss att undersöka detta.

Ljud och trädgård är kanske inte det första par man tänker sig som gifta men de tus historia kan spåras längre tillbaka i tiden än man kan föreställa sig. När jag bestämde mig för att skriva min kandidatuppsats om akustisk trädgårdskonst trodde jag att ljudinstallationer i trädgårdar och parker var ett nytt fenomen. En helt ny värld öppnade sig framför mina ögon då jag insåg att så inte var fallet. Konstgjorda ljudkällor, såsom gyllene fåglar och vattenorglar, har kommit och gått genom tiderna medan naturliga ljud, såsom vind och fågelsång, bestått. När det kommer till vår egen tid är trädgårdsljud, även om moderna material och tankesätt används, en konstform som starkt präglas och inspireras av sin historia. Du kan skapa olika sorters ljudmiljöer i din trädgård beroende på vad du väljer att använda för material.

Society?s interest for environmental issues was reinforced in the 1960:s when the book by Rachel Carson, ?Silent Spring?, came out. She described a picture of a world without birds singing and this got the environmental debate going. Today, this debate has reached the corporate world since stakeholders are putting pressure on companies to show greater environmental awareness. Many companies show uncertainty when they are faced with these new market demands.

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).

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

The bacterium Lactobacillus reuteri, which natural habitat is in the intestine of mammals and birds, uses glycerol as a substrate for production of the antimicrobial compound reuterin. Glycerol has been shown to decrease the number of Escherichia coli in human feces and it is believed to be due to in situ production of reuterin. E. coli belongs to the large family of Enterobacteriaceae, naturally occurring in the intestine, and pathogenic strains of E. coli have been shown to be one of several bacteria causing diarrhoea in calves.

Vid Masugn 3, SSAB Tunnplåt AB i Luleå, pågår arbete för att vidareförbättra råjärnets kvalitet genom minskad variation av Si och för att ytterligare minska förbrukningen av reduktionsmedel. För att få en ökad kunskap om tillståndet i den nedre delen av Masugn 3 utfördes i april 2004 en koksborrning ur tre av masugnens 32 formor. Försöken ingår i ett forskningsprojekt inom Jernkontorets forskningsprogram. Syftet med examensarbetet var att karaktärisera raceway och den döde mannen genom att studera borrkärnorna, processdata, koks från forma provtagen genom koksrakning, manuell mätning av racewaydjup och racewaydjupsmätning med radiometrisk utrustning. Till sist undersöktes bottentemperaturen tillsammans med andra parametrar, såsom råjärns- och slagganalyser och råjärnstemperatur, för att fastslå om den döde mannen var aktiv eller inaktiv.

Stormwater is surface runoff water that originates from precipitation or snowmelt and that on hardened surfaces prevents to infiltrate the ground. In city areas stormwater can consists of major amounts pollutants and when reaching a lake or watercourse it can cause damages on vegetation and animals. Therefore it is important to treat polluted stormwater before it reaches the recipient. The municipality of Örebro have since the 90ies an extensive work with treatment of stormwater in sedimentation ponds. A new stormwater treatment project is planned in an industrial estate in Skebäck, Örebro.

As we travel more and more by train it becomes increasingly important that the time we spend traveling, is of great quality. This has been the foundation of this master thesis and has shaped the outcome of it. The traveling experience, that is, the experience of the landscape that flashes by outside the train window, is an important aspect in railway planning and an aspect that should be taken into greater consideration. The purpose of this master thesis has been to examine how to compose or improve the travel experience for an already planned high speed railway and how the travel experience can be combined with other aspects, which have claims on the landscape. This thesis is based on a literature study and a case study of Ostlänken. The work describes Ostlänken, a planned high speed railway in Sweden between Järna and Linköping, with top speeds at 300-320 kilometers per hour.

The aim with this thesis was to investigate what characterises an English Arts and Crafts garden how they could be modernised in Sweden. My research was limited to 20 weeks of full-time writing and worth 30 ECTS. Through literature studies, interviews and site visits I could analyse my findings which resulted in a concrete garden design project. The Arts and Crafts was a movement that started in England during the 1880?s and evolved as a reaction towards the industrialisation. The influence came from the writings and practices of John Ruskin (1819-1900) and William Morris (1834-1896) who advocated the importance of craftsmanship. The Arts and Crafts movement also became a ?recipe for life? and was associated with a healthy and morally pure way of living.
