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.

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.

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.

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.

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.

Dolda resurser : Att synliggöra icke materiella tillgångar

Background: Once upon a time the most important resources in an economy were tangible goods. Historically, Swedish company culture has been dominated by engineering and techni-cal innovation has been the focal point. Today, Intangible values drive product development and form a company?s differentiation. Intangibles have therefore become the most prominent resources in a company.

Nässvalgsond på hund ? djursjukskötarens område?

The aim was to identify if the veterinary nurse is as competent as the veterinaian in placing a nasoesophageal feeding tube. The aim was also to identify the complications with malnutrition and the advantage and disadvantage of the procedure. This essay is based on several interviews with both veterinary nurses and veterinaries. 16 persons were asked 4 short questions in conjunction with an intensive care/emergency and surgery congress in Gothenburg in February 2013. In addition 4 major hospitals that provided intensive care were asked to answer 5 more detailed questions, one answer from a veterinary and one answer from a veterinary nurse was requested.

Stem injection of different nitrogen forms into young Norway spruce

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).
