Accelererat åldrande av produkter Apelsinjuice och hallondryck
Brämhults Juice AB is one of Sweden?s leading producers of fresh fruit juices and drinks. The fruit drinks last 3 days once opened and when stored in a refrigerator kept at 7°C. Since factors that shorten the drinks? best before date are usually not noticed until the entire batch has expired, it would be advantageous to find a way to accelerate the drinks? natural deterioration, so that an unusal short best before date is noticed before more products are shipped off to the stores.
Utveckling av provmetodik för HVAC på lastbil : - Klimatprovning i vindtunneln CD7
I detta examensarbetet undersöks hur provningen av HVAC på lastbilar skall utföras iklimatvindtunneln CD7 som Scania färdigställer till år 2013. HVAC omfattar kupéuppvärmning,ventilation samt AC och har därmed en stor betydelse för klimatkomforten inne i lastbilshytten.Med klimatvindtunneln CD7 kommer olika tester att kunna utföras i en kontrollerad miljö medallt från ökenklimat till snöig vinter. De nya möjligheterna som kommer med klimatvindtunnelnCD7 är även anledningen till att en ny provmetodik behöver undersökas och tas fram.Studien föreslår fyra stycken provmetoder för HVAC samt en struktur för dokumentationen.Provmetoderna som har valts fokuserar på sol-, regn- och snösimuleringar. Dessa provmetoder ärbaserade efter vad som kan samt bör testas i CD7, vilket är en del av syftet med examensarbetet.Solsimuleringar har i empirin visat sig vara bland de mest förekommande proven när det gällertestning av HVAC och klimatkomfort.Provmetoderna syftar till att skapa en utgångspunkt för konstruktörer och testingenjörer vidutformningen av prover. Det gör testningen repetitiv samtidigt som tid sparas genom attdokumenterat underlag finns att tillgå.En av målsättningarna med examensarbetet har varit att studien ska användas förvidareutveckling av provmetoder för HVAC på Scania.
Spridningsmönster och potentiella spridningsytor hos invasionsarten stor bockrot (Pimpinella major) i Tullgarns naturvårdsområde : ett framtida problem för områdets diversitet?
An organism that is transferred from one place to another, causing major problems to the native species is termed invasive. Its natural dispersal across barriers may have been prevented but as man has turned able to rapidly travel all over the world organisms are brought to sites where they were never before observed. Adding the increasing global warming organisms may find it necessary to move around even further. This might cause major disturbance to the biological diversity, and hybridization and homogenization is one of many scenarios that could disturb the native diversity. In Sweden more that 2/3 of all alien plant species have been introduced to disturbed areas and the major introduction mechanism is gardening.
H?llbarhetsprestation och finansiell volatilitet. En studie om sambandet mellan ESG-po?ng och aktievolatilitet
This paper aims to explore the relationship between financial risk and ESG scores in order to assist investors in making investment decisions. We investigate the hypothesis that there is a relationship between the ESG score of a company, and the financial risk in terms of volatility in the relevant company?s share price. The paper is grounded in sustainability reporting and financial risk. With the world facing significant changes and natural disasters, there is an urgent need for action to mitigate environmental impacts to avoid devastating consequences.
?Det är som att lägga ett pussel? Intensivvårdssjuksköterskors upplevelser av kommunikation med lätt sederade, respiratorvårdade patienter
Att vårdas i respirator innebär att den verbala kommunikationsförmågan förloras, vilket kan medföra känslor av frustration och maktlöshet hos patienter. För att uppnå en vårdande relation är samtalet av stor betydelse, vilket försvåras om kommunikationsförmågan är nedsatt. Syftet är att beskriva intensivvårdssjuksköterskors upplevelser av kommunikation med lätt sederade, respiratorbehandlade patienter. En kvalitativ ansats har använts. Halvstrukturerade forskningsintervjuer utfördes med åtta intensivvårdssjuksköterskor från två sjukhus.
"Bloggen är vad man gör den till" : en etnologisk undersökning av vardagsbloggarnas lockelser och konventioner
To many of us blogging is a natural part of our everyday life. Bloggers dedicate hours to writing in blogs, reading blogs, commenting on posts or answering comments on published posts. But what we choose to blog about can differ; this is an important note due to my discovery that what we choose to write about determines what benefits blogging holds to the blogger.This paper discusses the conventions of blogging as well as tries to answer the question of why blogging is so popular: why do we start blogging and why do so many choose to continue? These questions get answered by me analyzing the phenomenon that is blogging.I have studied both blogging as genre and as a kind of performance, as well as I have tried to hold an open dialogue with my informants. Thus I have concluded that blogging is to be considered a tool with many uses.
En undersökning av Bergvik skogs och Skogsstyrelsens gallringsmallar mot en gallringsoptimering på simulerade typbestånd
The purpose of this study was to analyze the two thinning models: Bergvik Skog´s thinning model, which is based on total stems and dominant height, And Swedish forest agency´s thinning model which is based on basal area, habitat index, dominant height and recommended number of stems at final felling in Heureka´s StandWise and PlanWise.
The data we chosen for our study were taken from the Swedish National Forest Inventory and we were creating a simulated stand based on a great number of sample plots in Region three from The Swedish National Forest Inventory. We had chosen to create one stand with low habitat index (T20) and one with high habitat index (T24). Our purpose were to come as close as possible to a natural stand in central Sweden. We performed the thinning in StandWise and analyzed the data I Excel files. Our thinning optimizing´s were performed and analyzed in PlanWise.
There wasn´t any big differences between the thinning on the lower habitat index.

Landskapsarkitektens potentiella roll i arbetet med återuppbyggnad av katastrofdrabbade områden ? samlade synpunkter
Förekomsten av naturkatastrofer runt om i världen tycks intensifieras och drabba allt fler människor. Människor som plötsligt står utan mat, vatten, tak över huvudet och med bristande energiförsörjning. Till synes som en reaktion på detta, växer det runt om i världen upp nationella och internationella organisationer i arkitektvärlden som vill utgöra en roll i återuppbyggnadsarbetet efter dessa katastrofer. Det verkar finnas ett stort engagemang bland både yrkesverksamma och studenter ? en vilja att vara en del av en världsförbättrande verksamhet.
Disciplinen vi delar - En innehållsanalys av magisteruppsatser vid Bibliotekshögskolan i Borås
This study is a statistical content analysis, of masters? theses written in 2005 at the Swedish School of Library and Information Studies in Borås. The relations between their epistemological discourses, theories, methods, themes and chosen alignment within the education, the so-called ?kollegium?/college, are examined. The results are put in relation to the concepts multidisciplinarity and interdisciplinarity to see what kind of discipline Library and Information Science (LIS) can be described as, on the basis of this material.
Flustret : en nattklubb utomhus

During the years the building has had numbers of different owners. The owners of today are running Flustret in a same friendly spirit that has been characteristic from the beginning.
The buldings history is now approaching an age of 165 years. Throughout the years different historical layers have been placed on top of each other, leaving a layer of patches.
Ungdomars läsvanor och hur vi skulle kunna inspirera ungdomar att läsa mer skönlitteratur
AbstractThe purpose of this work is to try to find out how young people's reading habits among students look at different types of secondary school, ie. both theoretical and practical, and what factors might encourage them to read more. My questions have been; do young people read today? Is there any difference between city, gender or program? What can a teacher do to inspire young people to read more? I have made a questionnaire survey among different students at two different high schools in Skaraborg. The first school is a high school located in a medium sized town, where I made inquiries to the scientific program, social program, Business and Administration Program and the Electricity Program.
Åtgärder för att minimera trafikbullers påverkan på ett rekreationsområde
The aim of this inquiry was to investigate the most appropriate measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls.
Plesiomonas shigelloides ? en ovanlig orsak till diarré hos katt? :
Plesiomonas shigelloides is a gram-negative, oxidase-positive rodshaped bacterium of the family Enterobacteriaceae. P. shigelloides is most frequently isolated in tropical and subtropical areas, but has also been isolated in colder areas for instance in Sweden. The primary natural habitat of the bacterium is fresh water and indirectly waterliving animals, but the bacterium can also be recovered from humans, mammals (of which cats are over-represented), birds, insects and poikilothermic animals. P.
Anestesi av ödlor
The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.
