Partikelformulering av fluider. Flödessimulering utifrån en partikelbaserad beräkningsalgoritm.

I fo?ljande arbete underso?ks en partikelbaserad simuleringsmetod som kallas Fluid-partikelmetoden, FPM. FPM a?r designad fo?r att simulera komplexa fluiders beteenden pa? mesoskalan, vilken sammanla?nkar kontinuumskalan med den molekyla?ra skalan. Metoden utvecklades av Pep Espan?ol i slutet av 1990-talet och a?r en vidareutveckling och generallisering av Dissipative Particle Dynamics som togs fram av Hoogerbrugge och Koelman under tidigt 1990-tal.

Optimization of Burner Kiln 7, Cementa Slite

In this report focus is put on the combustion process at a cement plant. Combustion is the heart of the cement making process and absolutely crucial to have under full control and well optimized. The fuel is put into the process through a burner pipe and this burner pipe is modified to reach a more efficient combustion. The primary target is to enable burning of heterogeneous alternative fuels and increase the production level. Other positive effects from this type of optimization is lowered specific fuel consumption and lowered CO2 emissions. A redundant burner is chosen for the project and overall the project steps are the following: 1. Installing a Jet air nozzle ring in a way so it can move both axially and radially due to temperature changes. 2.

Klinisk gradering av hästens luftvägsstatus : en jämförande studie av kliniska graderingsprotokoll samt deras relation till luftvägshälsa och neutrofilförekomst i BAL-vätska

Respiratory disease with airway inflammation as main characteristic is common in the horse. It is a syndrome that is not yet fully understood. The etiology, pathogenesis and classification into different disease states are subjects for discussion and under continuous revision. Despite a number of modern techniques, the diagnostic procedure is challenging. There is no test considered to be gold standard when diagnosing these diseases.

Molekylärgenetisk analys av dilaterad cardiomyopati hos hund :

Canine dilated cardiomyopathy (DCM) is a disease with high morbidity and mortality and with a high prevalence in certain breeds. Predominatly large breeds are affected, such as Great danes, Newfoundlands, Deerhounds and Dobermanns. One exception is Cocker spaniels, where both American and English Cocker spaniels are affected in a quite high frequency. Cardiomyopathy is characterised as a disease that affects the myocardium and gives an impaired heart function. To diagnose DCM following criteria have to be observed: 1. Dilation of the left ventricle. 2. Reduced systolic heart function. 3. Increased sphericity of the left ventricle. To be certain of the diagnosis, alternative reasons for the symptoms such as lung- and heart diseases with other etiologies have to be excluded Two different types of DCM have been found upon histological examination.

Vätskepreferenser hos unga kalvar

Den vanligast förekommande sjukdomen hos unga kalvar med infektiös orsak i Sverige är diarré. Enterit kan leda till uttorkning, acidos, rubbningar i elektrolytbalansen och i värsta fall dödsfall. Snabbt insatt behandling är avgörande. Till kalvar med fungerande digestionssystem rekommenderas i första hand behandling med oral vätsketerapi. Endast lite forskning har utförts om hur kalvar helst dricker sitt vatten.

Man och kvinna till salu : En studie av manliga kontra kvinnliga modemagasins framställning av genus och konsumtion

Due to the developments in today's gender discussions, this essay aimed at investigating the gendered constructions and encouragements to consumption. As a former fashion student I have a special interest in the commercial constructions featured in fashion magazines, especially since advertising, fashion and perceptions of gender have long walked hand in hand. Just as feminism studies have shown femininity being a fluid identity, recent studies of masculinities, media and culture are also showing changes in the depictions of men.The aim was to clarify how fashion magazines encourage men and women to consume products and ideals, and also discuss the gender constructions occurring in the junction of editorial and commercial text (articles and advertisements). The analysis was thereof based on three main questions:-       How is consumption encouraged in male and female fashion magazines?-       What kind of gendered pattern appears in the junction of advertisement and editorial text?-       With regard to the gender constructions, what is the reader encouraged to consume?The theoretical framework of the analysis was based on gender studies and political economy, mostly describing a commercial perception of feminine journalism and a new metrosexual expression in men?s fashion and lifestyle magazines.By using a combination of quantitative (content analysis) and qualitative (semiotics) approach two fashion magazines, Elle and King Magazine (published in May 2013) were used as representatives of fashion magazines in general.The results showed clear differences between the sexes.

Simulering av värmeförluster för kopparrör : En studie av värme- och strömningsparametrar för rörströmning

Att använda fjärrvärme till lågenergihus kan vara olämpligt pga. höga kulvertförluster jämfört med kulvertförluster för traditionella hus. Detta beror på att det låga värmebehovet i lågenergihusen ger en hög returtemperatur i ledningarna. Ett steg för att öka värmebehovet och göra fjärrvärme mer attraktivt för lågenergihus är att börja värma upp vitvaror (tvätt-, diskmaskin och torktumlare) med fjärrvärme istället för att använda traditionella eluppvärma vitvaror. Vid installation av dessa vitvaror tillkommer en rördragning vars värmeförluster är önskvärda att hålla nere för att dels säkerställa önskad temperatur till vitvarorna men även för att hålla nere internvärmen i huset.I studien har olika rördimensioner och isoleringstjocklek analyserats för att se hur värmeförlusterna beror på strömningsparametrar.

Patogenes för prostatacarcinom hos hund : en jämförelse med människan

This thesis investigates the possibilities offered to a working landscape architect by anincreased and altered use of digital 3D environments. A basic assumption is that increased useof digital three-dimensional environments promotes the creative processes and presentationoptions of landscape architects.The thesis is based on literature studies and communication with working landscapearchitects, and includes an investigation of the visualization methods available in the Blender3D modelling software. The thesis provides a thorough survey of what it means to model inthree dimensions, as well as of what modelling methods are feasible for a landscape architectto use. As landscape architects, we work with human and unique processes, and thus it isdifficult to develop standardized and automatic software for our profession. One possiblesolution is to turn to open source development, where software and models are shared andanyone can contribute.

Injektion till katt ? injektionsassocierad smärta samt injektioner i praktiken

Intramuscular injections to cats can generate strong reactions in some individuals while reactions of the same extent, according to the author, not always are recognized when using the subcutaneous route. The reactions are probably caused by fear, stress and/or pain. When the injection can generate pain one has to take that into account, which can be a limitation in treatment. It is well known that injections generate pain, but knowledge about the cause and processes of the injection-associated pain is limited. This is mainly due to the difficulty in finding objects to study pain on, high cost of use of laboratory animals and difficulty to obtain objective measurements. Although there is evidence that there may be a local muscle injury by intramuscular injection, it is not always that the extent of damage is related to the pain experienced. Facts about the causes of injection-associated pain have been studied in a literature review.

Syntes av hydroxyapatit/ nanocellulosa kompositer

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.

Energianalys av rörledning med överhettad vattenånga

Värmetransport är ett viktigt fysikaliskt fenomen med många olika industriella tillämpningar, till exempel värmning eller kylning av en fluid som strömmar i en rörledning. Den viktigaste mekanismen för värmetransport i strömmande eller stillastående fluider är konvektion. En bättre kunskap och förståelse för den bakomliggande fysiken skulle innebära att designen av systemen skulle kunna optimeras för att erhålla en ekonomisk process genom att minimera energiförluster och kostnader för material.En ångturbin i ett kraftvärmeverk producerar elektricitet genom att vattenånga strömmar igenom turbinen. Den överhettade vattenångan transporteras sedan från turbinen i en rörledning för att användas till uppvärmning av processer i ett närliggande massabruk.  I detta arbete har en energianalys genomförts på rörledningen med överhettad vattenånga efter turbinen för att bestämma temperaturfördelningen. Valet av material i rörledningen är beroende på tryck och temperatur och med för dålig kunskap om temperaturfördelningen längs röret riskerar konstruktionen att bli onödigt kostsam.En matematisk modell ställdes upp med de energibalanser som verkar på rörledningen.

Industriella avloppsvatten i Chile : Identifiering av problem samt förslag på åtgärder

Chile and Santiago are struggling with heavy environmental problems as a consequence of urbanisation and industrialisation. In the Santiago region the air is seriously contaminated and most of the rivers are classified as heavily polluted.The aim of this thesis is to survey the industrial fluid waste situation in the Santiago region and to make suggestions on technological improvements or process changes. The purpose is also to study five different enterprises more closely and to give more detailed suggestions for improvement. Another purpose is to summarize relevant Chilean legislation.Information, provided by the supervisory authority, about the release of industrial wastewater to rivers has been analysed. Deep interviews have been made with authorities and consultants.

Askans inverkan på beläggningstendensen i ett biobränsleeldat kraftvärmeverk och växtplatsens påverkan på askegenskaperna :

This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.
