Buntning av grot med lastbilsmonterad utrustning :

During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.

Dagbrottsdesign med IPCC

Mager är ett fiktivt gruvprojekt i planeringsfas och utvärderingar har gjort över projektet som visade att projektet är lönsamt. Boliden vill se om Mager kan stärkas ekonomiskt genom att tillämpa fullt mobil In-Pit Crushing and Conveying (IPCC). IPCC avser att förkorta ledtiden mellan grävare och kross genom att placera en kross innanför dagbrottets gränser och sköta materialtransporten ut ur gruvan med hjälp av ett transportband. Förkortningen sker antingen genom att förkorta körtiden för truckarna från grävare till kross eller genom att helt eliminera truckarna. Det finns tre stycken IPCC-system, stationär, semi-stationär samt fullt mobil IPCC.

Fixering av suggor ? så påverkas välfärd och smågrisdödlighet

Piglet survival is a problem of great significance in pig production, affecting both animal welfare and economic aspects negatively. In Sweden it is illegal to use farrowing crates for sows on regular basis. To encounter this problem there is a proposal of an animal welfare program to allow the use of crates for sows during, and a number of days after, farrowing. The proposal aims to reduce piglet mortality and improve pig welfare. This present review aims to analyse how crating affects the welfare of sows, gilts and piglets as well as piglet mortality.

The genetic background of oxytocin and its importance for maternal behaviour of sows

Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.

När och varför dör smågrisarna under diperioden?

The purpose of this study was to compile when and why piglets die during the suckling peri-od. Piglet mortality is an important factor influencing the profitability of piglet production. There are many factors that play a role and interact whit each other. This study summarizes when the piglets die during the suckling period and reasons why the piglets die. The infor-mation given is crushed, illness, management/environmental, genetic influence and piglet birth weight/farrowingprocess.

Katten i Bilderboken - Hur gestaltas katten i bilderboken och vad säger det oss?

The purpose of this essay is to look at how the depiction of cats is performed in childrens? picture books. I will analyze eight pictures from four different books, two from each. The books are from two different decades: from the 1960s and from the 2000s.My ambition is to see if there are any artistic or cultural differences when comparing the two decades? depictions of cats to each other.

Konstruktion och utvärdering av Current Conveyors

Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required performance. A component that use current as the signal conveying part is the current conveyor. In this report a comparative study between two current conveyor structures of second generation (CCII) is performed.

TV- produktion i ett förändrat mediesamhälle : En fallstudie på Go?kväll på SVT

The media society of today is changing. Because of a media convergence, traditional media distributers like television, radio and newspapers have to rethink their place and their purpose in the world. This paper brings a new angle to this area of research, conveying how creativity, workflow and media convergence is related to each other. A deeper understanding of these relationships gives us a clue about how media convergence can change the practice of TV- production. In this paper, a case study at Go?kväll in SVT is presented.

Prehospital omvårdnad vid risk för crush syndrom

Sammanfattning.Bakgrund:Crush syndrome eller traumatisk rahbdomyolys är vanligt vid större naturkatastrofer som tex jordbävningar. Det kan också uppkomma när personer utsätts för tryck mot musklerna vid tex stroke, intoxikationer, byggnadsras, industriolyckor. Inom ambulanssjukvården i Sverige har vi inte någon behandlingsplan för detta tillstånd och därför kan det finnas en risk att dessa patienter inte får rätt omvårdnad.Syfte:Studiens syfte var att belysa ambulanssjuksköterskans omvårdnad vid risk för Crush syndrome.Metod:En litteraturstudie gjordes för att granska redan publicerat forskningsmaterial. Sökningarna gjordes i databaserna Cinahl och Pubmed. Fem artiklar inkluderades och innehållet analyserades med manifest innehållsanalys.Resultat:De patienter som riskerar att få Crush syndrom har följande symtom: skada på muskelmassa, förlängd kompression, komprimerad lokal cirkulation, puls >120 och onormal urinfärg.

Att läsa mellan raderna : En studie i grafiska elements roll som identitetsbärare på magasinomslag.

Hard competition amongst the editorial world of magazines today has led to increased differentiation of the content as well as the visual communication. In this study, the graphic elements of the magazine cover was analyzed to establish how the magazines character is being conveyed by the cover design. In a case study the covers of the Swedish publications of fashion magazine BON and ELLE was semantically analyzed.The conclusion was made that the logotype plays the biggest part in conveying the magazine?s character. Secondly, the front cover headlines shape and size matter a great deal for the overall impression.

Exponera mera : ett arbete om skyltning på bibliotek

This Master s thesis deals with the display of library media, whether it is conceivable and desirable to draw inspiration from the retail business when displaying articles. The questions asked are: are there, in the retail sector, well established display ideas and - if so - what do they look like? Are the similarities in conditions, between the branches, sufficient? In conveying the ideas to libraries, are the potential differences not obstructive? Is there, among librarians, a positive attitude towards further development of library display techniques? The results were achieved by interviewing shop window dressers and librarians. In addition, a survey was sent to the library managers of 65 public libraries in southern Sweden. The results show that there are established ideas and methods of displaying materials, and that the ideas are manifested in frequently used techniques.

Brandgravar : Yngre järnålder i Broe, Halla socken, på Gotland : en studie i olika metoder, med fokus på kremeringen

This essay concerns the osteological cremated skeletal remains from Broe, Halla parish, Gotland of  The Late Iron Age.The focus of this essay is to determine the position of the corpse on the pyre, whether the cremated bones were crushed after or prior to the cremation and if the individual was buried in the pyre. In addition the species, age, sex and skeletal abnormalities of the bones in question will be studied.The result of the research has yielded that the cremated bones did not need to be crushed to result in the small fragment sizes. Crushing of the bones may have happened during the cremation, this conclusion has been drawn through the comparison of a pyre experiment were bone fragmentation is evident with cremated foxes, and dogs in the cremation graves from Broe. The construction of the pyre and the position of the corpse could not be determined through colouring and fragmentation of the bones.The human's were commonly buried in the pyre, and in some cases it is possible that the "grave" in fact is the remainder of a pyre. The species found are dog, horse, cow, sheep/goat and bear.

Metafor - Tao : En komparativ studie i metaforik mellan prekonfuciansk tanketradition och svensk nutid

Metaphors and their use as a rethorical vehicle are examined. Two texts, one in Chinese and one in Swedish, are compared and analyzed to determine the extent to which the associations they create successfully capture the author's intent. Seecondarily, a shift from the assumptions that rhetorical analyses often assume (read: antiquity and Aristotles) to a more abstract internal human platform is suggested. Neurological and cognitive research is cited in support of this shift.The essay examines the question: How can metaphoric contribute to conveying the communicator's intention? By comparing metaphorics used by an historical Chinese rhetor with those used by a contemporary Swedish rhetor.

In the light of increasing work- related ill-health in our society, it is important today to work with health-promoting initiatives in order to improve the well-being of people. It is advisable that an appointed key person at the work place works with health-promoting efforts.

Jakten på talang : En studie i hur employer branding kommuniceras effektivt till studenter

Purpose/Aim: To identify which channels of communication are most effective in conveying consumer brands to students. The main areas of research are social media, brochures , employees, and face-to-face interaction as with job fairs, study visits and lectures.Material/Method: Group interviews, literature, electronic sources, Internet sources.Main results: The results of the study show that employees are seen as the most trustworthy source since they are thought of as the most honest. Social media are seen as the communication channel with the broadest range of information but with the possibility of appearing unproffesional. Brochures were considered to be the least effective communication channel as these are rarely read and when they are, often seem contrived and give an overly rigid impression of the company. Face-to-face communication was considered to be the most effective way to gain a professional connection but was as viewed upon with certain skepsis due to the companies tendencies to at times present a false projection of themselves at events such as job fairs.
