Förekomst av Helicobacter spp. hos hund : samband med hepatit/pankreatit?

To date, the genus Helicobacter consist of 26 different species and even more species are yet to be characterized. Helicobacter has been detected in connection with diseases in the liver and pancreas in humans and animals. Helicobacter spp. are gram negative, curved, S-shaped or spiral shaped bacteria. They are microaerophilic and have flagella that make them motile. Helicobacter, present in the gastric mucosa neutralize the gastric acid through production of urease that hydrolyses urea to ammonia and bicarbonate.

Effekt på mark och gröda av olika bearbetningssystem, med och utan CTF

Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.

?Vem behöver anledningar när man har heroin?? ? En kvalitativ studie om socialsekreterarens erfarenheter av motivationsarbete med heroinmissbrukare ur ett förändringsperspektiv.

The purpose of this essay was to examine the different aspects of motivational work with active heroin-using clients from a social workers point of view. The further purpose of this essay is to also examine what the advancements and discouraging factors in such a motivational work might be. To attain this purpose we focused on these following questions:What might motivational work with active heroin-using clients look like?According to the social worker, what factors constitutes for a beneficial progress in the engagement of motivational work with active heroin-using clients?According to the social worker, what constitutes for discouraging factors in the engagement of motivational work with active heroin-using clients?We chose to do a qualitative study by conducting separate interviews with six social workers working in a social services agency, all of whom are working with drug-addicted adults. We then analyzed the answers by using an abductive research strategy, testing the collected empirical data against our chosen theoretical perspectives.

Sexualiserade rykten - en del av vardagen? : En studie av några unga kvinnors förhållningssätt till rykten.

The purpose of this thesis is to understand the ways in which rumors affect the everyday lives of a few young women. The questions are: What kinds of rumors do the young women find are the most common? How do they respond to these rumors? Do the rumors affect their everyday lives and if so, how do they react to them? Do they resist them? Do they feel limited by them?The empirical data was collected through unstructured interviews (focus groups) with three groups. The groups discussed different themes without prompting questions by the interviewer and it was clear that rumors played an important role, in multiple ways, in the lives of the young women. The most common rumors were sexualized and were mostly concerned with the view that the young women should not engage in ?too many? heterosexual relations ? preferably none.

Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua

Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.

Det ligger i luften - en enkät undersökning om kvalitetssäkring av ventilation på oprationssalen

ABSTRACTIntroduction: Postoperative wound infection is the third most common nosocomial infection in Sweden. The ever-growing problem of antibiotic resistance provides surgical departments a big challenge when it comes to preventing the spread of infection. Operating theatre nurses have a vital role in the prevention of infection. In addition, correct ventilation in the operating theatre is of great importance. The caregiver is responsible for quality assurance of ventilation in the operating theatre, but the work can be delegated to other staff within the department.

Breeding practices of Red Maasai sheep in Maasai pastoralist communities

A survey was undertaken to understand sheep management, breeding practices and selection criteria for Red Maasai sheep in Maasai pastoralist communities in Kajiado District, Kenya. Differences between North and South Kajiado District were investigated to gain knowledge about farmers having different prerequisites and how it can affect the sheep production. The reason for keeping sheep and the specific breeds show the multiple objectives of the Maasai farmers. Adaptive traits, such as resistance to diseases and droughts, and productive traits, such as increased growth and carcass weight, were both ranked highly. In addition to this, the sheep has a social and traditional value in Maasai culture.

Klövform och klövsjukdomar hos intensivt uppfödda köttrastjurar :

The top selection of Swedish beef bulls are evaluated yearly by Svensk Köttrasprövning AB at Gismestad. The bulls are selected from six different breeds; Angus, Blonde d´Aquitaine, Charolais, Hereford, Limousin and Simmental, and are kept on straw bedding apart from a concrete alley in front of the feeding area during the six months of evaluation period. The bulls are evaluated according to their fertility scores, growth, exterior and temperament and the exterior, body posture and claw conformation reflect important qualities for their longevity. In spite of good values for fertility, it has been noticed in the last years that the fertility results and longevity have been unsatisfactory and claw and/or bone disorders have been suspected as a contributory cause. Persson et al. (2007) studied breeding bulls from Gismestad and other places, which had been slaughtered due to poor fertility (no pregnancies in the herd during their last year in service).

Järnåldersgården som försvann : En studie av produktion, tafonomi och brända ben från möddingen vid gården Långåker från romersk järnålder

This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).

Projektledarutbildningar på svenska universitet och högskolor : Innehåll och relevans för yrkesrollen

One year Master's thesis, Degree of master in Business and Economics, School ofBusiness and Economics at Linnaeus University, Management, 4FE10E SpringSemester 2014.Author: Johanna Björklund and Sarah Gustafsson.Mentor: Magnus Forslund.Title: Lean in the public sector - Potential barriers to a long-term Lean work.Background: Organizational changes are something that is constantly done inorganizations, and in the last decade, there has arisen a plethora of different changemodels. A reorganization that is popular among companies today is Lean. Lean is aconcept that was developed within the Japanese automotive industry, but has evolvedfrom the Japanese shop floor and is now a concept that can be found in, for example,several Swedish municipalities.Purpose: The purpose of this study was to create an understanding of why the conceptLean may have difficulty getting a hold in the in the long term.Methodology: The study was done with a qualitative research approach and through anabductive approach. As we intended to create an understanding, of what potentialbarriers that may affect that a Lean work, in some cases, does not become a long-termcondition, it seemed natural to choose a hermeneutic approach to knowledge. Theempirical data collected via individual unstructured interviews, through a groupinterview, and by non-participant observations.

Delaktighet och motstånd i samband med organisationsförändringar: en studie av två fall på Kappa Kraftliner i Piteå

För att dagens företag ska klara av den föränderliga omvärld och den globala konkurrensen är företagens förmåga att genomföra organisationsförändringar en mycket viktig faktor. I förändringsarbeten kan företagens förmåga att skapa delaktighet och bearbeta motstånd vara det som avgör huruvida förändringen blir framgångsrik eller inte. På Kappa Kraftliner i Piteå har det de senaste åren genomförts flera förändringsarbeten. Vi har i den här uppsatsen undersökt två stycken förändringar som genomfördes på andra halvan av 1990-talet. Den första kan sägas ha genomförts för att nyansera och bryta ned företagets övergripande mål på grupp- och individnivå samt öka engagemanget och få de anställda att ta mera egna initiativ i den dagliga driften.

Hur påverkar gummigolv i grisningsboxen suggans liggtider, liggbeteende och hennes tid för att lägga sig?

In the farrowing pens the amount of bedding material and the quality of the concrete floor has a huge impact on both the sow and the piglets. In this study imbedding of rubber flooring on the solid area in the farrowing pen was used to see if it had any effects on the sows lying behaviour when compared to concrete. Another important aspect was to evaluate if the rubber floorings had a high enough durability to resist the normal wear in a farrowing pen. Concrete flooring is assumed to have a higher thermally conductive effect then rubber which can affect the sow?s chance to cool down.

Överlevnad och tillväxt för nyplantersade barrots- och täckrotsplantor : en studie av 42 bestånd i södra Sverige

The choice between bare-rooted and containerized seedlings in southern Sweden affects the investment costs as well as growth and survival. It is important to take these differences into account when choosing seedling type for reforestation. The most important differences between the two seedling-types is that bare-rooted seedlings has open root systems whereas the roots of containerized seedlings are grown in a container which may contain water and nutrients that are available for the seedling during the first period after planting. Moreover, bare-rooted seedlings are often older which results in thicker stembase and better resistance to attacks of pine-weevil (Hylobius abietis). In order to study differences in survival and growth between bare-rooted and containerized seedlings a survey study of newly planted clearcuts in south-western Sweden was made. In the study tree seedling types was included, one bare-rooted and two containerized with different ages. The population of pine weevils was probably low during the studied period which resulted in lower pine-weevil damage than normally found in this area.

Att delta och förändra, trots kaos! - En studie om Försäkringskassans organisationsförändringar.

Earlier the regional social insurance office was exposed to critisism because of bad administration and a lack of providing public service. Among other things the regional social insurance office was attacked because of long investigation hours and indinstinct working methods and was blamed for not being able to solve the unhealth in the society. This lead to the reformation of the previous regional social insurance office into a government authority agency on the first of Januari, 2005. Extensive organizational changes were made so that regional social insurance office could handle the demands and become a uniform public administration. I have made a qualitative study where the purpose was to se how the changes affected the public administrators and I focused on their participation and willingness to change.
