High Cereal Prices : An analysis of the causes behind the increase in the world market price of corn, rice and wheat.
The purpose of this study is to examine which factors played an important role in the food price crisis of 2007-2008. Theories used are Microeconomic theory, explaining changes in supply and demand, and Macroeconomic theory, explaining the impact of changes in exchange rate on prices. A theory regarding speculation is also used to explain the impact of speculative activities effects on price. The method used is multiple regression analysis in order to determine the effects which ethanol production, oil price and dollar exchange rate had on the surge in the price of corn, rice and wheat.The data used is in monthly observations during the period 2005-2008. However, other factors are taken into consideration during the study, such as production quantity, stock size, economic growth, speculative activity and population growth.
Indirekt blodtrycksmätning hos hund och katt :
The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.
Normativa data för samband mellan subglottalt tryck och ljudtrycksnivå
Syftet med föreliggande studie var att undersöka sambandet mellan subglottalt tryck och ljudtrycksnivå, och undersöka inverkan av kön och tonhöjd. Röststyrkan är starkt beroende av subglottalt tryck och sambandet har analyserats i ett flertal studier, som alla visar på ett linjärt förhållande mellan logaritmen av subglottala trycket och ljudtrycksnivån (SPL). Schutte (1980) analyserade sambandet för 21 kvinnor och 24 män som producerade ett stort antal mätdata med olika SPL och tonhöjd. Tryck mättes med ballong i esofagus. Tanaka & Gould (1982) analyserade 4 kvinnor och 6 män på tre ljudnivåer på bekväm tonhöjd; svag, normal och stark ljudstyrka.
Feta kontra magra mejeriprodukter vid primärprevention av hjärt- kärlsjukdom. En systematisk översiktsartikel
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Whole fat versus low-fat dairy products for primary prevention of cardiovascular disease. A systematic review.Author: Josefine Lindqvist, Robin Järnmark, Mathilde OhlinSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2014-04-09BackgroundResearch indicates that dairy products seems to have a protective impact on the incidence of cardiovascular disease regardless fat content. Paradoxically the Nordic nutrition recommendations recommend an exchange of full fat dairy product to low-fat dairy products.ObjectiveThe aim of this review is to investigate whether the variation in fat content of dairy products have any bearing on the onset of cardiovascular disease. With regard to common risk markers for cardiovascular disease the outcome measures hypertension, hyperlipidemia and weight gain is examined.Search strategyThe searches were made in the databases Medline (23/1-14) and Scopus (6/2-14).Selection criteriaRestrictions: Human Studies, Adults, Randomized Controlled Trials, English.Data collection and analysisTwo RCTs were included. Validation of the separate studies was performed with SBU's review template for individual studies and GRADE was used for summarizing the evidence of outcome measuresMain resultsThe two included studies examined the outcome measures blood pressure, weight and blood lipids.
Torkning av vallfrö :
In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the
fields, this is primarily used as feed for livestock. To get a good seed, you need to
handle the crop carefully from planting to delivery. The part that I have been
interested in, is how to dry the harvested seed with out destroying the growth in the
small seed. This is very easily done if you aren?t careful during the drying period.
Undersökning av metoder för att analysera och modellera efter stora datamaterial, hantering av programmet SPSS samt en studie i Kronoberg läns gymnasieelevers psykiska ohälsa
The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.

The power consumption has grown rapidlyin the last decade. Fossil fuels and theneed for alternative energy sources aregreat. Ocean waves are a renewable andsustainable source of energy that hasbeen relatively untapped. At UppsalaUniversity research and development havebeen done for several years. Severaltypes of wave energy converters (WEC)have been created.
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.
Den lokala lobbyn : En studie om informella kontakters betydelse för kommunala beslut
Forskningen om lobbyism i Sverige har hittills i huvudsak fokuserat på riksdagen. I den här uppsatsen undersöks lobbyism på kommunal nivå utifrån ett mottagarperspektiv med fokus på beslutsfattare och deras erfarenheter av lobbyism. Syftet är att belysa hur beslutsfattare i svenska kommunfullmäktige uppfattar att lobbyism går till i sina egna kommuner. Studiens utgångspunkt utgörs av lobbyismens relation till demokrati och i den kvalitativt genomförda undersökningen används en analysram baserad på tre värden för demokratisk lobbyism, benämnda transparens, jämlikhet och etik. Empirin har samlats in genom intervjuer med åtta kommunala fullmäktigeledamöter.
Om att lära sig prestera under press
I have researched different methods for practicing with the purpose of learning some useful ways to handle my performance anxiety issues, to better understand the phenomenon, and to be able to perform better under pressure. I chose or created nine methods and used each during a decided period of time, each period ending with a performance. Afterwards I analyzed the methods with the help of audio recordings and written concert evaluations to see if it was possible to alter my practicing techniques to be more directly focused on preparing for the concert situation..
Den övertygande reklamen? : En analys av Pripps Blå och Norrlands Gulds reklambilder
Modern societies are generally becoming increasingly capitalist in nature and economies of these societies are thus likely to become more focused on consumer consumption. Advertising plays a vital role in contemporary society where we, as consumers and citizens, are surrounded by it everywhere we look and everywhere we go. This puts pressure on advertisers to become more creative and to explore new ways of marketing their products and services in an already saturated environment. We believe that the added pressure and the already established role of marketing in society make advertisements an interesting and telling object for analysis. This is particularly the case with regards to the concept of selling and marketing products that have qualities that are known to be less than beneficial for our health.This paper analyzes four commercial advertisements marketing beer; a product that we argue has qualities that can be seen as potentially bad for the health of individuals and for societies.
Metoder för blodtrycksmätning hos hund
Tillförlitlig blodtrycksmätning hos hund är viktigt för att kunna upptäcka avvikelser som kan orsaka eller kopplas samman med sjukdomstillstånd. Flera olika former av blodtrycksmätning existerar, men metoderna har utvärderats i varierande grad. Syftet med litteraturöversikten var att undersöka vilka fördelar och nackdelar det finns med olika metoder för blodtrycksmätning hos hund.
Viktigt vid utvärdering är att mätningarna sker simultant, eftersom blodtrycket varierar mycket mellan olika tillstånd och situationer. I huvudsak finns två typer, direkt och indirekt blodtrycksmätning.
Den direkta mätningen är invasiv och innebär att en kateter med trycksensor sätts in i en artär, vilket kräver gott handlag. Direkta mätningar anses bäst återspegla de ?sanna? värdena och används ofta som ?golden standard? vid utvärdering av indirekta metoder.
Neonate mortality in fallow deer (Dama dama) in relation to bed-site selection and habitat use
The level of neonate mortality in a free ranging fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.
Ny huvöppningslösning för Eco-Logs skördare : Från idé till tillverkningsunderlag
This thesis has been made in cooperation with the forestry machinery producerEco-Log in Söderhamn. The focus of the thesis has been to find a cheaper wayto open the large engine hood of the company?s harvesters. The goal was tofind a solution that could increase the value for the customers by being saferand simpler to use, or, at the least, keep these values at an equal level comparedto the previous solution.In order to make it possible to CE-mark the new solution, it was importantMachinery Directive that came into effect from the beginning of 2010.To begin with, a specification of requirements was set up. Thereafter, anumber of different basic concepts was retrieved and evaluated.
Sjukgymnastiska behandlingsmetoders evidens mot smärta vid myofasciella triggerpunkter i nacke, skuldra och ländrygg : En systematisk litteratursammanställning
Myofasciella triggerpunkter (MTrP) är ett relativt vanligt problem hos befolkningen. Det största problemet för de drabbade är smärta men det kan även orsaka rörelseinskränkningar samt ge refererad smärta. Diagnosen ställs enligt Simon och Travell utifrån ett antal olika diagnoskriterier, så som palperbara knölar i muskulaturen och ökad känslighet på och runt dessa. Sjukgymnastiska smärtreducerande behandlingsmetoder kan delas upp i invasiva- eller icke invasiva metoder. Syfte: Syftet var att genom en systematisk litteratursammanställning kartlägga evidensen för olika smärtreducerande sjukgymnastiska behandlingsmetoder vid MTrP i nacke, skuldra och ländrygg.
