Analys av blått och grönt vattenfotavtryck för nötkött från ICA:s sortiment
ICA vill utveckla sitt miljöarbete i vattenfrågor. Denna rapport syftar till att öka medvetenheten hos ICA om verksamhetens miljöpåverkan genom att analysera vattenfotavtrycket ? vanligen kallat Water Footprint ? för ett livsmedel. Vattenfotavtryck är ett verktyg inom miljösystemanalys som används för att kartlägga sambandet mellan produktion och konsumtion av produkter och vattenanvändning. Studien visade att vattenfotavtrycken är ungefär 14 500 liter/kg och 16 500 liter/kg för svensk respektive irländsk nötfärs.
En j?mf?rande studie mellan tv? v?treng?ringsmetoder p? papper
Amongst the published literature researching wet cleaning of paper there is a limited amount of
studies conducted researching the method simmering water treatment. There are even less studies
conducted on how simmering water affects the paper being treated when used as a cleaning method.
Despite the limited research, there are literary reviews describing the method and suggesting it as an
alternative for conservation of paper with iron-gall ink. The following study will therefore be
examining, the somewhat unusual method, simmering water treatment, and comparing it to one of
the more common wet cleaning methods: immersion washing. This is done to compare how the
different temperatures of the water affect the paper.
The types of paper used in this study consists of three dyed and four undyed papers. All of the papers
are new, apart from one sample originating from 1847.
Driftoptimering av torkmaskin : Driftoptimering av torkmaskin 3 vid Billerudkorsnäs Karlsborg AB
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Energieffektivisering genom förvärmning av flis till kokare med sekundärvärme
The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.
Stadsnära hav : en intervju/enkät om upplevelsen
The environment that surrounds us affects us all. Research
has shown that we feel physically and emotionally best in
natural environments with greenery or water elements. Urban
environments are likely to be more stressing then natural
environments. How we experience specific elements, as water,
of an environment is not as much investigated. There is a need
of further knowledge for us to fully understand the interplay
between our senses and the environment.
Human beings have always been depending on water and the
search for it has characterized our deeds and doings through
out evolution.
Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.
DEHP - från mjukgörare till hormonstörande
Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.
Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :
The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.
Rederiers hantering av nya miljökrav : En studie om Birka Cruises, Tallink Silja och Viking Lines arbete med ekonomisk och miljömässig hållbar utveckling
The purpose of this study is to examine how Viking Line, Tallink Silja and Birka Cruises work with economic and environmental sustainability, and also to see how they work with new environmental legislations. In 2015 a new environmental legislation will be introduced, by the name Sulphur directive. The Sulphur directive entails a reduction in Sulphur dioxide emissions from ships where the emissions cannot exceed 0,1 percent. There are three alternatives to achieve the new environmental legislation, the use of Marine Gas Oil, LNG or scrubbers. All three alternatives will lead to increasing costs for the shipping industry.
Sambandet mellan revisionskvalitet och längden på revisionsuppdraget : empirisk undersökning av Going Concern varning
That an auditor brings good quality to the work he is performing is of great importance, not only for the company in question but also for its stakeholders. The information that the company disclose gets more credibility because of the auditor quality assurance. That the auditor tenure would affect the quality has been researched with different results, dependent on the legislation in the current country or region. In this paper we study how audit quality is affected of the audit tenure in Sweden. Based on research made in Belgium we have formulated hypothesis with factors that can affect the audit quality.

"Det blir vad man själv gör det till" : -En kvalitativ studie om ensamhet och livskvalitet bland äldre.
Abstract This is a qualitative study of elderly people's experiences of loneliness and quality of life. Also the relationship between loneliness and quality of life are examined. Previous research has shown that social loneliness is about when the social context are lost while emotional loneliness can occur with the loss of close relationships. Quality of life is about a sense of connection but also the quality of life arises in the difference between the expectation of what one is and what one wishes to have. This study has shown that the interviewees preferences, activities, social networks and low expectations on their life situation makes interviewees perceive themselves to be less lonely and have a good quality of life.
För naturens bästa : en studie av svensk kvalitetsmärkning av ekoturism
Nature?s Best is a quality-label for Swedish Eco-tourism. It is one of very few active ecotourism labels and the only one that claims quality as its main focus. The objective of this thesis is to evaluate the certification scheme Nature?s Best with regards to the values the certification creates for the companies that certify their products.
Nitrat i grundvattnet : Modellanalys av vattenflöde till Hörviks vattentäkt
A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.
Kvalitetsbegreppet i äldreomsorgen : En idé som speglar samhället
The purpose of this study was to understand how the concept of quality as an idea was spread to and translated in municipal elderly care. A central question was: How does literature, policy documents and key people describe the function and meaning of the concept of quality? The method of analysis was a qualitative case study with a critical discourse. The theoretical framework of the study is mainly what is known as institutional theory and a line of thought describing how ideas are transferred and spread. The theoretical focus is on how original ideas are interpreted and why they gain a foothold in new contexts.
