AbstractDegree thesis Solid content in Lime Mud By Andre Flodin Process operator program ? Umeå University 17/6 ? 2014 Pages: 21A thesis was made on Billerudkorsnäs production unit in Karlsborg where lime kiln in the causticising department of chemical recovery plant does not meet the required production. Causticising department is the final step in the chemical recycling unit. There, the filtered green liquor is mixed with lime to recover the cooking chemicals used in the pulp factory. The cooking liquid is called white liquor.
Strömmar av vatten och politik - en studie om policyprocesser och anpassning.
One of the distinguishing features of successful societies is the ability to adapt to change, bothsocial but also natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and highly built up coast line along with factors like deficient handling ofsurface runoff and a large usage of ground water leads to an increasingly vulnerable society. Italso puts a greater pressure on the society to have preventive measures in place.The number of actors working with preparing society to the expected impacts of climatechange and variability is increasing. However more than half of Sweden?s municipalities donot consider changing climatic conditions when planning, and many times even allow theconstruction of new living areas in known climatically vulnerable areas.
Lämna inte slumpen åt slumpen - En studie om hylloptimering i den digitala butiken
This paper examines the impact of conscious shelf management on online grocery stores. An S-O-R framework is used to unveil if some established shelf management techniques from physical stores are applicable in an online context. We also explain some of the cognitive processes customers experience as they get exposed to online buying situations. A main study with two data sources is conducted: one quantitative website experiment with 168 participants who got exposed to five different organisation patterns within five different categories; and one more qualitative eye tracking experiment with 20 participants. The results indicate that a disorganised product page evokes not only different scan paths and cognitive patterns but also generates higher sales.
Ledarskap och etik : En studie om Strukturellt etiskt klimat & Situationsbaserat etiskt beslutsfattande i fastighetsmäklarbranschen
AbstractTitle: Leadership and ethics in the Real estate agent-industry Level: Final assignment for Bachelor Degree in Business Administration Authors: Paula Massamiri & Therese Delmar Supervisor: Lars-Johan Åge, Jonas Molin & Jens Eklinder Frick Date: 2014 ? May Purpose of study: The aim of this study is to create an understanding of how leaders trough a Structural ethical climate can contribute to a Situation-based ethical decision-making of their employees. Method: We have used a qualitative method and conducted semi-structured interviews with respondents from real estate agent firms. When we studied our phenomenon, our overall research deign was qualitative interviews. Our data has been analyzed with an abductive method of analysis, influenced by Grounded theory. Results and conclusions: The study shows that leaders in the real estate agent-business trough a Structural ethical climate contributes to a Situation-based ethical decision-making of their employees by acting as role models, leads by example, highlighting the office values and rewards & punishes behaviors to control their employees? ethical decision making. Suggestions for further research: We believe that future studies can be conducted through observations to study both leaders and employees, to pay attention to employees? opinions and reflect on what affects them.
Carbon Critical Masterplanning tool : klimatpa?verkan fra?n samha?llsplaneringsprojekt
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.
Detaljminne vid påverkan av emotionell arousal
Forskning visar att människor huvudsakligen återger starkt emotionellt laddade händelser väl. Information och detaljer runt omkring händelsen har dock visat sig vara betydligt svårare att rapportera, jämfört med centrala detaljer som är kritiska för den känslomässiga upplevelsen. Syftet med föreliggande studie var att undersöka effekter av emotionell arousal beträffande minne för central respektive perifer detaljinformation. Hypotesen var att negativt känsloladdad information påverkar minnet positivt beträffande centrala detaljer, men negativt för perifera detaljer. Två experiment utfördes, där kontrollgruppen i båda experimenten förevisades 15 neutrala färgbilder föreställande vardagliga situationer.
Leanuppgift för industriprogrammet
The government regulations for energy use in buildings will be tightened in the future. At the same time the interest in environmental classifications and certifications of buildings is increasing. This has meant a new situation for solar energy. The designs of solar heating systems are often based on experience and/or rules of thumb, rather than calculations and simulations. This thesis examines whether simulation tools, in this case Polysun, are useful in this work.
Phycoremediation of pesticides using microalgae
Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and
mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity
in biosorbing heavy metals.
Energieffektivisering på Vista
Sweden has distinct seasons with cold winter and temperatures down to minus 25 ?C andpleasant summers with temperatures above 20 ?C. During spring and autumn there could becomechallenges with precipitation. The diverse climate in Sweden affects many homeowners. For thepeople living in leisure boats and permanent housing boats the seasonal changes are clearlyimpacting their economy and the indoor climate.
Utdragshållfasthet av inlimmade skruvar i limträ
In this thesis tests has been performed on the pull strength of screws glued into glulam beams.The experiment is based on the already approved method whereby the diameter of the drilled holes is the same as the screw outer diameter of 1 mm or bigger. The screws strength class shall not be less than 4.6 (EN ISO 898-1:1999, 1999).The difference in the experiments that were performed where that the drilled diameter were 1 mm smaller than the outer diameter of the screw so that the screw thread was worked into the wood.In the tests the gluing where made on M8 glulam beams. The screws where drilled at and angel of 90°tangental to the fiber direction with a diameter of 7 mm. The gluing of the screws where made in three different depths and where later exposed to pulling forces. The results showed both pulling breaks and screw breaks when they reached their maximum capacity.
Studie av glasfasader för kommersiella byggnader
Den klassiska approachen till navigering innefattar att agenten håller en intern representativ modell av omgivningen. Denna approach har emellertid många nackdelar, speciellt för dynamiska miljöer. En modernare approach är att förlita sig på den faktiska omgivningen istället för en modell av denna. Detta arbete presenterar en undersökning av navigeringsproblemet och hur väl det löses av agenter vars kontrollmekanismer utgörs artificiella neurala nätverk. Tillförlitligheten hos de två neurala arkitekturerna Extended sequential cascaded network och Self-organized recurrent network bestäms genom experiment.

Audiovisuell kontra skriftlig stimulans: En jämförande studie mellan effekten av video och text på gymnasieelevers kort- och långsiktiga minnesförmågor.
Denna studie har genomförts för att belysa skillnader i olika mediers roll för minnet och lärandet hos elever i gymnasieskolan. Syftet har varit att jämföra audiovisuell stimuli i form av utbildningsfilm med motsvarande information i skriftlig version utifrån ett kort- och långsiktigt perspektiv, då båda dessa medium används inom skolan utan några egentliga kunskaper kring deras för- och nackdelar. Två jämförande experiment med andra- och tredjeårselever på gymnasiet har genomförts där eleverna har indelats i olika testgrupper. Hälften av eleverna har vid experiment 1 sett på en utbildningsfilm, medan resterande har läst motsvarande information i skriven text. Därefter har ett omgående kunskapsprov med fasta svarsalternativ genomförts, följt av ett liknande prov tre veckor senare.
Klimatsäkrare städer : klimatförändringar, stadsplanering och översvämningar
The numbers of natural disasters caused by extreme weather are increasing through out the world. A large majority of the research concerning the climate shows that this is a trend that can be expected to continue. At the same time the urbanisation is increasing more than ever and for the first time in history more than fifty percent of the population lives in a city. How we build these cities will have a crucial importance for our adaption to the new climate. In Sweden, our capacity for an adaption are high because of our economic situation as well as our rather well built society.
Fisk- och fågelpredations påverkan på den bentiska makroevertebratfaunans sammansättning under tidig vår i Tåkern
Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).
