The Swedish forest industries' view on the future market potential of nanocellulose

General concerns about environmental issues may mean that the demand for bio-based products will increase. Opportunities that arise on markets, together with the declining demand for newsprint, may trigger firms in the Swedish forest industry to increase their development of new products. One product that has received a lot of attention during recent years (and is a contender) is nanocellulose. The purpose of this master thesis was to examine the Swedish forest industry?s view on the market potential of nanocellulose.

Perkolationsfilter : En undersökning av reningseffekt med avseende på järn och mangan

This master thesis has been done in cooperation with Sweco Viak AB in Sundsvall. The aimwith the project is to investigate the purifying effect of percolation filter due to iron andmanganese. The overall goal was to investigate how the parameters surface load,sandfractions, and burden time affect the purifying effect. The expectation is to optimize thedesign and find a demouldning of the filter that gives sufficient purifying with a highersurface load. As an attempt to accelerate the curing of the filter, experiments with a layer ofsand which surface has been covered with manganese ore (MnO2) on top of the filter havebeen done.As test filters 10 L bars were used and the experimental work was performed at thewaterworks in Hassela and Munkbysjön.In Hassela different sandfractions were tested.

Folkbibliotekens webbplatsers grafiska användargränssnitt Kvalitativa intervjuer med webbansvariga

The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.

Förändringar i markanvändning över tid och dess påverkan på vattenkvalitet

The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.

Nitrogen flow in Scania : substance flow analysis on a regional level

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

Att aktivera deltagande : Design av ett crossmediakoncept

In this thesis we present the procedures and outcomes of adopting two roles in a study: the role of a researcher and the role of a designer. The subject is crossmedia design. Crossmedia is a growing and changing trend for media producers of today its design is of great importance. The purpose is to create a concept from scratch that stands out from the crowd and engage people with the use of cross media as the approach. We also aim to investigate if a cross media designer can rely on previous research made within this subject or if the scene has changed.In order to test and to fully understand the process of the subject, we designed a crossmedia concept, based upon previous and related research.

Identifiering av designriktlinjer lämpade för integrerade videouppladdningstjänster

There is a lack of published material regarding designing graphical user interfaces of so called integrated video uploading services. The term integrated video uploading services refers to homepages that do not have video uploading as its primary purpose but which still offers that service to its visitors. The aim of this thesis was to improve the amount of published material about designing graphical user interfaces for integrated video uploading services. This was done by performing a literature study to find general design guidelines which can be applied to design of integrated video uploading services. Thereafter the functionality and design of dedicated video uploading services was analyzed.

Uthållig sanitet : en förstudie i staden Picota, Peru

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.

Automatiserad konstruktion av analoga förstärkare

The last few decades the development in the field of electronics has been huge. The components performance gets better at the same time as the manufacturing cost decreases. Many of the design moments that have to be done, are done automatically today, but it can get better. Especially for analog circuit design.At Electronic System in Linköpings universitet, research is in progress to develop a tool that can design analog circuits in reasonable time. It means that it has to size the components (transistors, resistances, capacitances etc), so that the circuit can fulfill the performance requirements.

Studenters hälsa vid Växjö universitet : ? en studie med KASAM, symtom och krav-kontroll-socialt stöd som utgångspunkt

The aim of this study was to examine the relationship between gender and self reported symptoms (physiological and psychological) and sense of coherence (SOC) and Job Demand-Control-Social support (JDCS). The sample consisted of 360 respondents (nfemale= 261, nmale= 99), in the ages between 19-53 (M=25,57, SD=5,77), all students from Växjö University. A quantitative work method was used in the study; data was collected using questionnaires that consisted of self-reported questions, based on three parts: A modified symptom checklist, SOC 13 and a modified JDCS questionnaire. The result of our study showed that both SOC and JDCS had an effect on self-reported symptoms but there were no interaction between SOC and JDCS. No significant gender differences were found regarding the level of SOC.

BRISTER I MÄRKNING AV LIVSMEDEL? HUR PÅVERKAR DET OSS?

An organisation in Skåne, Miljösamverkan Skåne, presented a project in 2011 concerning food labeling. All municipalities in Skåne, audited certain products in several stores, in order to determine if they were labeled correctly according to law. Stores who produced their own food where also audited. As Swedes generally have an interest in buying and cooking food from different countries, the demand is increasing, which makes stores provide the customers with a large range of different products to accommodate the demand. This essay will discuss the results of the project and how incorrect food labeling can affect human health.

Djurskyddsinspektörer : - Behovet av kunskap om exotiska djur

Psittacines and reptiles are exotic animals that are difficult to care for and it requires extra knowledge to make a correct assessment of their wellbeing. An animal welfare inspector, with an education in general animal welfare, may not have a deep enough knowledge of exotic animals to do a proper assessment of the animal?s general condition and its environment. In this paper it was therefore examined if animal welfare inspectors have enough knowledge to do a satisfying inspection of establishments working with selling of exotic animals. A literature study was used to examine difficulties with each species.

Water balance and nitrate leaching from arable land in a changed climate : a model study

This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.
