Punktmolnshantering i anläggningsprojekt : Utvärdering av programvaror för framtagande av markmodell
An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.
A screening for Schmallenberg virus among sheep, goats and cattle in Zambezia province, Moçambique : and preparations for a metagenomic survey of virus in mosquitoes
As the world´s population increases and people's living conditions are improving, larger areas are needed for houses as well as food production. This means that
new areas are exploited and that people, livestock, blood sucking insects and wild animals are forced to live close together. In combination with the global warming,
leading to extreme weather such as floods and storms, this allows both new and old pathogens to emerge. The number of "emerging infectious diseases", EIDs, has increased in recent years and many of them have their origin in poor, tropical countries. Moçambique is therefore considered to be a high risk area for EIDs.
Schmallenberg virus, SBV, was discovered in 2011 as an "emerging infectious disease" in dairy cows in Germany.
Periodisk fasta i kombination med styrketräning ökar muskelmassa och minskar fettvikt hos yngre vuxna
SammanfattningBakgrund: Dagens stillasittande livsstil med ökat intag av energigivande ämnen resulterar i ett konstant anabolt hormonellt påslag. Detta leder till ökad övervikt och andra välfärdssjukdomar. Det rekommenderas att individer håller sig till en hög måltidsfrekvens med jämna mellanrum under dagen. Detta har börjat ifrågasättas med konkurrerande alternativ som involverar en tidigare samhällslivsstil så långt som 10 000 år sedan, då måltidsfrekvensen inte kunde planeras på samma sätt som idag.Syfte: Syftet är att under sju veckor undersöka effekten av två stycken veckovisa 24-timmars periodiska förbud mot intag av energigivande ämnen, med implementering av fysisk styrketräning och dess effekt på lean body mass (LBM) och fettvikt hos yngre individer.Metod: Två separata 24-timmars perioder av fasta i samband med tre separata styrketräningstillfällen genomfördes per vecka under sju veckor. Kroppsmått gällande kroppsfett i procent, fettvikt i kilogram (kg), kroppsdimensioner i centimeter (cm), LBM och total kroppsvikt i kg togs innan och efter studiens genomförande.
Kylning och torkning av ett högtryckskompressorinlopp
Examensarbetet utfördes på University of Florida vid Department of Mechanical and AerospaceEngineering i deras Energy and Gas Dynamics Systems Laboratory. Laboratoriet forskar på enny gasturbincykel som producerar kraft, värme, kyla och vatten. Cykeln är kallad High PressureRegenerative Turbine Engine (HPRTE) och kombinerat med gasturbincykeln är ettabsorptionskylsystem (VARS). Kylsystemet drivs av spillvärme från avgaser som cirkuleras igasturbinen, den producerade kylan används för att kyla ned högtryckskompressorinloppet.Syftet med det här examensarbetet är att undersöka möjligheten till att kyla ned inloppet tillkompressorn till temperaturer långt under fryspunkten för vattnet i den fuktiga gasen. Om gasenskall kylas till nivåer under fryspunkten måste vattnet föras bort från gasen.
Metodutveckling för analys av PBDE och HBCD i sediment
Brominated flame retardants (BFRs) has for many years been used in products to reduce their
flammability, mainly in electronic products, textiles and construction materials.
In 2003, Sweden imported 300 tons of brominated flame retardants.
Leakage of these compounds has polluted natural environments. Fishes has shown increased
contents of these substances, especially fat fish, since brominated flame retardants tends to
accumulate in fatty tissues.
They are also regarded as persistent and that gives them the ability to travel long distances.
What also is really scary is that increased levels of brominated flame retardants have been
detected in human breast milk.
The knowledge of the brominated flame retardants is limited and not so much research has been
done in this field. There are many reasons though, to keep the research going. Partly their
structural resemblance to well-known toxics as PCB, but also their ability to accumulate in
biological systems and enrich in food chains.
In which way they affect humans we really don?t know yet.
KORTSIKTIG PRODUKTIONSPLANERING I MINDRE FJÄRRVÄRMESYSTEM : En studie vid Strängnäs Energi AB
District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.
Avloppsvattenbehandling med membranbioreaktor : En jämförande systemanalys avseende exergi, miljöpåverkan samt återföring av närsalter
In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).
Fosforprocesser i Bornsjön, Stockholms reservvattentäkt - dynamisk massbalansmodellering med LakeMab
Bornsjön är Stockholms viktigaste reservvattentäkt och kan tillgodose staden med dricksvatten i flera månader om Mälaren skulle slås ut. Det är därför viktigt att Bornsjön håller en god vattenkvalitet. Under de senaste åren har vattenkvaliteten avseende totalfosfor i Bornsjön försämrats. Hög belastning av fosfor kan leda till övergödning i en sjö. När en sjö är övergödd uppstår ökad syreförbrukning som kan leda till syrebrist.
Methane production from dairy cows : relations between enteric production and production from faeces and urine
Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.
Finska immigranter i Katrineholm : Politiska hegemoniers och sociala relationers betydelse för immigranters politiska integration och aktörskap i ett svenskt lokalsamhälle 1944-1991
The present memorandum outlines the structure, theoretical starting points and disposition of a thesis about the activities of Finnish immigrants in a Swedish local community, more specifically their political integration. The intention is to study the municipality of Katrineholm in the years 1944 to 1991.Previous research about the actorship of immigrants in spheres such as politics, labour unions, immigrant associations, educational associations and mass-education, as well as churches and religion, is presented to give an overview of possible areas connected to political integration that can be studied. The overview of previous research also covers local immigrant politics.The intended theoretical starting points for the proposed thesis are political economy and hegemony. The latter is intended to be investigated through its expression in the social relations class, gender, ethnicity, nationality and generation. It is suggested in this memorandum that hegemonies and social relations within a local political economy can be operationalised fruitfully in a study of political integration.
Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor
In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.
Skolsköterskans erfarenheter av tillväxtkurvan som arbetsredskap: ?Kurvan är en del i allt det andra?
I skolsköterskans uppdrag ingår att erbjuda hälsobesök till eleverna. Där ingår ett hälsosamtal samt kontroll av bland annat vikt, längd och Body Mass Index (BMI) enligt riktlinjer från Socialstyrelsen. Längd och vikt ses i relation till barnets genetiska, sociala och psykologiska förutsättningar. En avvikande tillväxtkurva kan påvisa förekomst av ohälsa av somatisk, psykisk och/eller psykosocial karaktär. Skolsköterskan gör den primära bedömningen av tillväxtkurvan och en felaktig bedömning kan få konsekvenser för eleven i form av en utredning i onödan eller uteblivna åtgärder.
Implementering av Patientsimulator för Anestesimaskiner
In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.
Emigration och Amerikabild - Om utvandrarens bildvärld och världsbild med utgångspunkt i emigrationen från Västernorrland till Amerika 1901-1909
I uppsatsen undersöks bildens betydelse för den svenska utvandringen till Amerika vid 1900-talets början. Utgångspunkten är i Västernorrland och en analys av Örnsköldsviks Allehanda,Allers Familj-Journal och Hvita Stjern-Liniens rederibroschyr. Under antagandet att varjebild fick ett större nyhetsvärde i en mer bildfattig kultur än den vi har idag och sparades underen längre tid är syftet att undersöka den blivande emigrantens bildvärld och världsbild. Frågorsom behandlas är: I vilket källmaterial förekom bilder, vilken funktion fyllde de och vilkenkunskap om Amerika kan den blivande emigranten tänkas ha haft? Vidare behandlasemigrantens bildbiografi, emigrationsbildens ontologi och bilden som emigrationspåverkandefaktor.
Trädgårdsergonomi : om konsten att undvika de vanligaste riskfaktorerna för hälsan i små trädgårdsföretag med krukodling
This paper is based on a literature review and interviews made with managers in small-scale nurseries for pot plant production. The review helped to identify the worst occupational hazards in pot plant production. The interviews provided a way to investigate how the nurseries act so as to avoid the worst hazards and what they do to even out work intensive periods during the season in order to get a more even distribution of work over the year.
According to available statistics problems with back and shoulders are the most common of the physical disorders and the risk for occupational accidents are high for greenhouse workers. Most of the occupational injuries are connected to musculoskeletal problems. The handling of material is often manual and involves frequent lifting and carrying of heavy loads, the strenuous work postures and static muscular tensions these repetitive tasks are associated with causes straining and overloading.
