Magsår hos gris : förekomst och faktorer som påverkar

Gastric ulcer is a common disease among pigs in the whole world where an intensiveproduction occurs. It is mainly the upper region, the nonglandular region of the stomach thatis affected. Gastric ulceration is a disease with several risk factors. The factor that seems tohave the largest impact on the development of gastric ulceration is a small particle size of thefeed. The reported prevalence of gastric ulceration differs from 5 to 100 % and it is a largeherd-to-herd variation.

Utvecklingsprinciper för eftersatta naturlika dungar och ridåer

Nature-like plantations are areas that, by today?s maintenance procedure usually gains low prioritiy and are forgotten. Most nature-like plantations are currently disadvantaged and have in many cases grown up and formed dense,impenetrable and brushwoody green volumes. These green volumes is rarely used, but usually only fills out gap surfaces. With proper care nature-like plantations can become health promoting environments in the increasinglyhardened urban environments.How vegetation systems work and how trees and shrubs interact is dependent on many factors.

Verktyg för värdering av miljöpåverkan vid investeringar i det svenska elstamnätet

During the period 2009-2013, investments in the Swedish national grid increase by a factor of ten compared to previous years. In order to fulfil their mission to manage the national grid in a safe, efficient and environmentally sound way, Svenska Kraftnät (Swedish National Grid) needs to take all these perspectives into account while planning new investments. To compare and relate perspectives of technology, economy and environment the same yard stick must be used. That yard stick is commonly money. A problem arises however as environmental issues are difficult to price.The purpose of this master?s degree project was to develop a tool for evaluation of environmental impact related to investments in the Swedish national grid.

Naturanpassat bostadsbyggande :

I am in this essay to find out how to successfully combine new development with preservation of natural values, mainly large scale vegetation and ground formations.This is done by studies of three developments. The first development, Engeltofta backe, lies 7 km northeast of Gävle. The expectations of natural preservation were not fullfilled when this area, after the explotation, did not have any vegetation of value left. The second example, Östra Kvarnskogen in the community of Sollentuna, shows, as far as one can tell at the moment, a sucsessful combination of new development and preserved nature. The third example is a development in the community of Kullön. In this area the ambition of combining preservation and development was fullfilled. After studying vital documentation in each planning process, I made interviews with different actors in each of the three processes. I thereafter compared the different documents and answers from the interviewed persons to find out if there were any significant similarities or differences which could be of importence when natural values is to be preserved in new developments. My conclusion of this study is that it is of great importence to define key expressions often used in the process, such as natural values and preservation.

Behovet av blyhandskar som skydd mot sekundärstrålning vid röntgenundersökning av djur

X-rays are a potential risk for animal health care personnel. The present study will examine the risks for scattered radiation to the personnel, if no lead gloves are used when holding an animal during the x-ray examination. Furthermore, how the impact of the exposure values and body parts examined, affect the scattered dose to the hands of the holder. Also, the distance between the animal and the hand that holds it was evaluated to see the impact on scattered radiation exposure. Tested by a survey, to animal health care students, the frequency of the usage of lead gloves in Swedish animal hospitals was studied. According to the results from the analysis, animal health care personnel don't need to use lead gloves every time they hold an animal or a cassette during x-ray examinations.

Branded for life: En kvantitativ studie av hur tatueringar på butiksbiträden påverkar kundnöjdhet

The purpose of this thesis is to evaluate whether or not tattoos have an impact on perceived customer satisfaction. We constructed an experiment where a service worker's physical appearance was manipulated. Our result indicates no significant impact of tattoos on customer satisfaction. However, the thesis succeeds to replicate previous findings on the links between physical attractiveness, attitude and customer satisfaction, and creates a ground for further discussion on the subject of tattoos in a professional environment..

Återvändarna : en undersökning av hur det svenska samhället påverkades av återvändande emigranter 1860-1940

Between 1860 and 1940 approximately 1,1 million Swedish citizens emigrated to North America. But over 200 000 of them returned to Sweden. In this essay I have tried to estimate the impact of these people on the Swedish society. To make a deeper analyze possible, I have studied the parish of Glima?kra in southern Sweden and tried to trace the immigrants? lives after their return to Sweden and thus estimate their impact on society.By statistical analysis of migrants between Sweden and USA and between the parish of Glima?kra and USA I have concluded that the result can be used as a model for Sweden on a national basis.

Outnyttjade resurser inom park- och naturvård

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Utveckling och psychometrisk testning av "Pain Impact Inventory" - en jämförelse mellan två olika ansatser

The aim of this study was to develop and psychometrically evaluate an instrument for measuring the impact from chronic pain on daily life. Traditionally psychometric evaluation is done with parametric methods even if the items are ordinal data. In this study the instrument to be developed is solely based on ordinal data, and the psychometrically evaluation is done with both traditional methods (i.e. parametric statistics) as well as with non-parametric methods. These two different ways of psychometrically evaluation are then compared with each other.

Dagsljusets gestaltande förmåga : en studie av dagsljuset och dess samverkan med vegetation i inglasade miljöer

Det här examensarbetet har som syfte att undersöka dagsljusets gestaltande förmåga i inglasade miljöer. Hur det är möjligt att använda dagsljuset i samverkan med växtlighet samt färg, form och textur hos miljöns fysiska element för att påverka den rumsliga upplevelsen. Ljus i ett rum är påtagligt närvarande, något som inte går att ta på men på samma gång kan dess strålar ibland uppfattas närmast som materia. Ljuset är variationsrikt och en avgörande förutsättning för visuell gestaltning. I det här arbetet har jag fått använda mig av synsinnet som ett mätinstrument genom att visuellt utvärdera upplevelsen och hur dagsljuset beter sig i några inglasade miljöer. I kombination med min personliga upplevelse av platsen har även kvantitativa mätningar av ljusets styrka gjorts.

Hur långt kan man gå? : En kvalitativ studie om fyra pedagogers syn på elevinflytandes omfattning och förutsättningar

Student influence is a well debated subject and all Swedish teachers should let the students influence their education. According to research the student influence is generally low and something that varies from school to school. The school policy documents do not clarify how much impact the students get to have on their education and the impact is therefore something that every individual teacher decides. These individual differences are the reason of this study.This is a qualitative study about four teachers work and thoughts focusing on the subject of school democracy and student influence in the school environment. The study is based on qualitative interviews in order to highlight four different teacher?s thoughts.

Impact Bias och Empathy Gaps : - en studie om skillnader mellan känslor och preferenser.

Syftet med föreliggande studie var att försöka reda i litteraturen kring två välkända begrepp inom Affective Forecasting nämligen Impact Bias, som innebär att människor har en tendens att överskatta i vilken utsträckning de kommer att uppleva en viss känsla i en framtida situation än vad som senare visar sig vara fallet, och Empathy Gaps, som innebär att människor har en tendens att underskatta i vilken grad känslotillstånd kommer att påverka deras preferenser i en framtida situation samt pröva dessa begrepp i en och samma enkätundersökning. Etthundra sextiotvå studenter, slumpvist uppdelade i två grupper, Känslogrupp och Preferensgrupp, deltog frivilligt i undersökningen. Enkätundersökningen var en mixad design med grupp (känsla kontra preferens) som mellangruppsfaktor och förtest kontra eftertest som inomgruppsfaktor. I studien visade samtliga gruppers resultat i linje med Impact Bias teorin, dvs. att deltagarna i både Känslogrupp och Preferensgrupp skattade lägre i eftertest (actual) än pretest (forecasting).

Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.
