Impact of Eucalyptus plantations on pasture land on soil properties and carbon sequestration in Brazil
Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.
Svenska som andraspråk : En kvalitativ studie av utformningen av undervisningen inom andraspråksinlärning
The purpose of this qualitative study is to understand and examine the problem andreason why second language pupils have difficulties reaching the goals of thecurriculum in ?Swedish as a second language?. The study is based on interviews withtwo second language teachers and Vygotskijs and Antonovskys theories. The interviewswith teachers gave a broader view on why these difficulties exist and whatconsequences might occur. This analysis shows that there can be different reasons as towhy pupils can not reach the goals in their second language that are set for them.
Framtagning av ett nytt recept för clear-coat batter av pommes frites : En teknisk och sensorisk utvärdering
The requirements of good quality and appetizing fast food increases continuously as a consequence of a community where food is always available. The crispiness of French fries is an issue that must be considered in this context, since it tends to decrease and give the fries a soft surface not appreciated by the consumer. To prolong the crispiness, the fries can be coated by a batter, a mix of starches. The batters used often consists of modified starches, e.g. cross-linked, acetylated and dextrinizated to increase and prolong crispiness, flour to stabilize the batter and sodium bicarbonate to make the batter ?rise?.The cross-linked starch keeps the granules in a swelled state and prevents them from breaking when exposed to heat or processing: therefore, it delays the gelatinization and decreases the stickiness of the batter.
Utvärdering av ramverket JQuery for mobile
Examensarbetet har utförts på Lawson, som idag gör en satsning mot de mobila användarna. Då det idag finns många olika typer av enheter, webbläsare och operativsystem utvecklas det mobila applikationer till varje plattform vilket medför stora kostnader och längre utvecklingstider. Den här rapporten är skriven i syfte att se över vad det finns för möjligheter att använda ny teknik som HTML5 och CSS3 tillsammans med ramverket jQuery for mobile för att utveckla webbapplikationer.För att visa på funktionaliteten och vad man kan göra så har två exempelapplikationer tagits fram och testas på flera olika plattformar/enheter, bland annat en iPad och en Samsung Galaxy Tab 8.9. Koden för dessa applikationer finns som bilaga i rapporten.Målet var att se över vad det fanns för stöd för swipes, enhetlig native-design/känsla, kunna använda enhetens kamera och GPS. En hel del, bland annat swipes, GPS och lokal lagring, går att lösa med HTML5 och jQuery for mobile.
Genetic variation of ASIP and MC1R in past and present sheep of Gotland
Ovine black coat colour is determined by the MC1R (Melanocortin 1 receptor) and ASIP (Agouti signalling peptide) genes at the Agouti and Extension loci. The black phenotype is caused by production of eumelanin by melanocytes, whereas yellow-tan or light phenotype is the result of phaeomelanin synthesis. The ovine MC1R gene has two known alleles: the wildtype (E+) and the dominant black (ED) alleles. Two missense mutations (c.218T>A and c.361G>A) constitute ED. The presence of a third allele, the e allele, is proposed and believed to give rise to phaeomelanic phenotype.
Detektion av kolvläge i hydraulcylinder med elektromagnetisk metod
The purpose of this study was to examine what students themselves think about using computers in school. The study was conducted in a school in central Sweden. The students in focus were students with reading and writing difficulties, dyslexia or language difficulties such as an other native language. A total of eight students were interviewed. The interviews were analyzed using thematic analysis.
Studier av alkaliskt fosfatas och kollagen samt deras betydelse för skelettets mineralisering
There is convincing research which shows that the enzyme alkaline phosphatase (ALP) has a central role in the mineralization of bone, more precisely that its catalytic activity is needed in the process. ALP is found on the surface of matrix vesicles where the mineral is formed. One theory about the function of the enzyme is that it binds to fibrous collagen in the bone and thereby incorporating the mineral into the bone. The purpose of this study is to establish whether ALP binds to collagen. If this is the case, more elaborate studies around this will be performed.
Arbetslöshet bland utrikes födda på den svenska arbetsmarknaden : En empirisk analys av vilka kommunala faktorer som kan påverka den höga arbetslösheten bland utrikesfödda
Unemployment amongst Swedish citizens is higher within the group which falls under the designation foreign-born. The aim of this thesis is to examine which municipal factors that can explain the differences in unemployment amongst foreign-born relative to native born.The empirical models are examined with both cross-sectional data for the year of 2010 and panel data for the years of 2002-2012. The examination is implemented through a linear regression analysis of the type Ordinary Least Squares (OLS) and Fixed Effect regressions. A theory section will be presented where the theory on Non-Accelerating Inflation Rate (NAIRU), theories on discrimination and country-specific human capital are illustrated.The result from the cross-sectional data shows that the amount of foreign-born, the level of foreign-born immigrated from Nordic countries have a significant negative effect on unemployment amongst foreign-born. The general unemployment shows a significant positive effect on the unemployment amongst foreign-born.
"Är en omogen människa grön?" : Lärares strategier och tankar kring ordinlärning för elever med svenska som andraspråk.
Learning words have shown to be a very crucial part of learning a second language and the one most important factor to make pupils with Swedish as a second language succeed in school. To make sure that all pupils get the right conditions to learn from all subjects and their entire content a wide vocabulary is necessary. Even so it is found that there are shortcomings regarding this kind of teaching in Swedish schools.Through interviews and observations of two teachers that teach pupils with Swedish as a second language, and also with a short reading test for the pupils, the possible strategies that these teachers use for learning words have been studied. The result shows that the teachers are using several strategies and that they are actively working with transmitting these to the pupils, but there are some areas that need developing..
Applikationsutveckling i Responsive Web Design
Responsive Web Design (RWD) har på kort tid gått från ett koncept till en av de största trenderna inomwebbutveckling. Det är nästan underförstått idag att nya webbsidor ska vara i RWD. Trots det är inte RWD detsjälvklara alternativet som löser alla problem dagens utvecklare står inför när det gäller den stora floran av surfandeenheter.I examensarbetet djupdyker vi i tekniken, både praktiskt och teoretiskt, för att kunna dra slutsatser om RWDs styrkoroch svagheter. Detta åstadkoms genom att ta fram en applikationsplattform och en första applikation(semesterplanering) åt konsultföretaget Sigma AB, där ett av grundkraven var att det vi utvecklade skulle kunnaanvändas varsomhelst.Utifrån våra resultat lämnas rekommendationer på när RWD är alternativet att satsa på och när det behöverkompletteras av andra tekniker, så som Native- eller HTML5 applikationer..
Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry
Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.
Challenges and Opportunities in Swedish Apiculture
Bees are of importance for the global food security. In Europe 84% and in the World 35% of all the agricultural crops are dependent of animal pollination (Winfree et al., 2011:1). In agricultural production there is a huge lack of pollinators (Azien & Harden, 2009). A problem that is widely spread. In Sweden the problem becomes clear when looking at the statistics of the number of bee colonies during the last 20 years, where it has been a decline with 63 % (Statistiska Centralbyrån & Jordbruksverket, 2011).

Den ociviliserade "norrlänningen" - en studie om social kategorisering och stereotyper
In this thesis we have tried to show the problems that the categorisation of ?norrlänningar? generates. We have also tried to describe what the stereotypes of ?norrlänningar? are by examining what people say on web logs. The method we have used to find the stereotypes in our empirical material is the discourse analyse.
Modersmålsstöd i förskolan/Native Language support in the kindergarten
Syftet med arbetet är att undersöka modersmålsstöd i förskolan, vilka reflektioner det finns kring modersmålsstöd samt hur modersmåltränare, förskollärare och barn upplever att det fungerar i förskolans verksamhet i Malmö stad. För att få en djupare förståelse av ämnet har vi valt att använda oss av en kvalitativ metod, detta genom att intervjua tre förskollärare och tre modersmålstränare. Vi har även varit ute och observerat barn i verksamheten under tillfällen då modersmålsträning skett.
Resultatet av undersökningen visar att modersmålsstöd i förskolan överlag fungerar bra men att det finns områden som kan förbättras. Modersmålstränarna upplever att de blir bättre bemötta idag och förskollärarna anser att samarbetet fungerar bättre nu än det gjort tidigare.
