Optimering av blandning och lagerhållning av avfallsbränsle : Optimering av avfallsbränsleblandning och lagerhållning av importerat avfallsbränsle vid Vattenfalls fjärrvärmeverk i Uppsala
Fjärrvärmebranschen i Sverige har sedan mitten av 1990-talet varit i en stagnationsfas, där mängden producerad och förbrukad energi i stort sett varit konstant, trots stora investeringar i fjärrvärmenätet. Samtidigt har den höga andelen återvinning gjort att det råder brist på avfallsbränsle till energiåtervinning i Sverige. I kombination med hög konkurrens om avfallsbränslet har detta medfört att aktörerna på marknaden tvingats se sig om efter nya vägar att tillfredsställa behovet av bränsle, vilket lett till att det idag importeras stora mängder avfall för energiåtervinning från utlandet. Vid Vattenfalls fjärrvärmeverk i Uppsala har det mellan åren 2006-2013 återvunnits i snitt drygt 360 000 ton avfall per år. En stor del av detta hämtas in från lokala kunder, både kommuner och privata aktörer, men man har på senare tid även behövt börja importera avfall för att tillfredsställa energibehovet.
On the hunt for improvements : possibilities of increasing welfare in captive cheetahs through hunting enrichment
The cheetah (Acinonyx jubatus) is one of the big feline species kept in zoos worldwide. The wild populations are quite small and therefore the captive population make up an important part of the total population of the world. Although life in the wild is not always easy and a captive environment provides shelter and food it does not come without problems. In captivity cheetahs become chronically ill and also develop stereotypic behaviours. Neither of these are problems in wild populations and both can be linked to stress in captivity.

Metod för beslutsstöd vid formulering och uppföljning av en kommuns klimatmål : fallstudie Uppsala kommun
The purpose of this study is to create a method that can be used to produce decisionsupport data for the climate goals of a municipality. The method should be able to demonstrate
the potential for reducing energy use and greenhouse gas emissions for measures aimed at the stationary energy system in the municipality. It will be used to make longterm
projections of energy use and greenhouse gas emissions in order to be able to demonstrate the ability to reach climate goals.
The aim was also to test the method's applicability by using the municipality of Uppsala and the Uppsala climate protocol project in a case study. Uppsala climate protocol is a project consisting of participants from business, government and organizations that voluntarily want to commit to reducing their carbon footprint by reducing their energy use and thus work to achieve the municipality's overall climate goal.
Public reporting of energy use and climate impact has been studied in order to examine the nature of indicators and accounting figures that are commonly used in the field and
how long-term forecasts are formulated. In connection to this, the type and sources for the kind of data needed was also examined.

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.
Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.
Utvärdering av VAV i nybyggt kontorshus
VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.
Kommunalt klimatarbete : Jämförande studie mellan tre kommuner med avseende på drivkrafter och framgångsfaktorer
The crucial factor for successful municipal climate work is that there are driving forces. Most importantly is that the senior officials and politicians in the municipality are dedicated to the cause considering that they have the power to influence and make a change. Besides proactive and committed individuals, it is necessary that the work is organized and anchored by clear and concrete documents and control systems. It is also important that the work is continuously monitored and evaluated. To collaborate with other municipalities, authorities or participate in various networks is another factor contributing to the improved climate work in the form of exchange of information, knowledge and experience.A major driving force for municipalities to improve themselves is the distribution of state aid and grants.

Stress och otillräcklighet upplevs av allt fler yrkesverksamma inom vård och omsorg idag. Lång tids stress ökar risken för en rad olika besvär och sjukdomstillstånd och därmed också risken för långvariga sjukskrivningar. Sjuksköterskeyrket som profession innebär många olika potentiella stressfaktorer på arbetsplatsen då det är ett yrke som efterfrågar hög kompetens, samarbete i många olika situationer, ständig tillgänglighet och emotionellt engagemang. I ICN:s etiska kod anges att ?Sjuksköterskan sköter sin hälsa så att förmågan att ge vård inte äventyras?.
Energiberäkningar för passivhus
AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.
Fuktkvotens inverkan på oljeupptag och pigmentinträngning i tall (Pinus sylvestris L.) och gran (Picea abies L. Karst) vid impregnering med Linotechmetoden :
Wood has always been an important material for people, and it is used for many applications. As for example, fuel for cooking and heating houses, construction materials and for constructing means of transport. Since wood also is a material that with time biologically degrades due to activity by micro organisms and wood fungi it is important to find ways to protect and further lengthen the life span of the material when in service. One method is to decrease the amount of water in the material by impregnation with an hydrophobic oil. The Linotech method which uses only pure linseed oil is one such possible method.
The aim of this study was to investigate the possibility to at the same time impregnate and stain/colour wood samples of pine and spruce by using the Linotech method.
Optimering av produktionstidsplan : Studie baserad på implementering av ny planeringsteknik i Peab Sverige AB
Now a day?s there is dramatic change from traditional to digital information processing in construction industry. This change can be visualized in the project concept stage where it now has accessibility to join all the data in one place. Location-based planning technique simplifies scheduling by visualizing the schedule efficiently and has many advantages such as might shortened the project period by about 10 - 20 % if the company uses location-based technology, reducing risks in many ways by maintaining production continuity and identify collisions between things etc. Vico Office software has been used for Location based planning technique and in this thesis.The purpose of this thesis work was to demonstrate how location -based planning technology change the scheduling stage in Peab, potentially reducing the project time.
Välfärdsproblem hos mjölkkor i stora besättningar
The aim with the literature study is to inform about the risks that exists in large dairy farms(with focus on mastitis and hoof health) and to inform about the milk industry in Sweden.Personal comments from two study visits (Nötcenter Viken and Vadsbo Mjölk AB) arelinked together with the literature and forms into a discussion regarding sustainableagriculture versus the milk cow's welfare.The profitability for Sweden's milk farmers have decreased because of the decreased milkprice and current inflation. This leads to an increase in herdsize in order to make a profit.The milk cow herds in Sweden becomes fewer year by year and the herdsize increases. Theincreased herdsize can cause a decrease in the time the farmer spends per animal. This canaffect early disease detection and prolong the animals suffering.Swedish Board of Agriculture published (2008) statistics showing that today's milk cow ismedicated primarily because of two reasons; mastitis or hoof problems. Mastitis is thereason to two thirds of all treatments that are carried out.
