Energikartläggning och driftoptimering genom behovsstyrning i befintlig fastighet
Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.
Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project
The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations.
The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.

Nytt ventilationssystem till djurstallar :
There is two dairy farms in Sweden with ability to be opened on both long sides, one outside
Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results
or not enough literature about natural ventilation and especially on this kind of air inlet, makes
my tests very interesting not only on Alnarp, but among other companies.
I would like to find out if there is any air movements direct on the cows, how high/low
temperature, air humidity, light intensity and noise standard inside the barn. Does
Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could
this system become the new dairy barn instead of the conventional barns in Sweden?
I am going to focus on the animals environment, after all they are the one who is going to
spend the most of the time in the barn.
I used five electrical loggers distributed inside the barn to measure the temperature and one of
the loggers measured the air humidity, every 15th minute. One logger were placed on the
outside which measured both temperature and air humidity.
Naturlig förekomst av arsenik och avskiljning av arsenik från grundvatten : test av olika filtertekniker avsedda för enskilda brunnar
During the last few years the presence of high arsenic (As) concentrations in ground water has been of major concern both internationally and in Sweden. Much evidence has been reported about toxic effects caused by arsenic. The carcinogenic effects and the possibility to measure the toxic impacts at low concentrations made the World Health Organisation (WHO) to reduce the guideline value from 50 to 10 ?g l-1 in 1993. In Sweden the corresponding reduction was implemented in 2003.
Several surveys in Sweden have shown that high arsenic concentrations may occur in ground water.
Askgödsling och dess lämplighet i torvmarksskogar tillhörande Sveaskog Förvaltnings AB : en litteraturstudie
During whole-tree harvesting, there is a risk that the soil will become impoverished of nutrients. To prevent this, nutrients are returned to the harvested site as wood ash. This action also reduces the risk of soil acidification. Nevertheless, the ash does not result in any increase of tree growth if it is added on mineral soils, which is where the measure is most commonly used in Sweden. Due to the lack of growth response, the interest from landowners is small, which is why ash amendment today is not done enough to compensate for the need.
Hur tillgänglig är staden? : fallstudie av Kungsgatan och Föreningsgatan i Malmö
How accessible is the city? Is there more factors than merely the strictly physical that affect how accessible the city is perceived? These questions are the starting point of this study. The greatest emphasis, in this study, is placed on the perceived parameters that affect us humans when we move in our cities. Experiences and internal images can change our behaviour and prevent free movement in the city. The result from this study shows that a city can not be seen as fully accessible unless both the physical and the perceived accessibility are fulfilled.
Vattentäta och ?andande? textilier
Rapporten innefattar en jämförande studie mellan olika typer av membran och beläggningar.Främst sker en jämförelse mellan materialens förmåga att andas. Vattentäthet testas på nyamaterial och efter olika sorters nötning så som martindale, flexing och tvätt för att få en ökadförståelse för materialen. Verktyget som används i studien för att mätaånggenomsläppligheten är hudmodellen. Resultatet presenteras med ett Ret-värde vilket är enförkortning på Evaporative resistance of a textile. Metoden används för att på ett bra sättsimulera hur huden svettas.Projektet har utförts på Swerea IVF som är ett forskningsinstitut beläget i Mölndal.Hudmodellen är en av de senaste stora investeringarna på Swereas textil och plast avdelning.Resultatet av studien visar att laminat andas bättre än beläggningar, dock har bärarmaterialetstor inverkan på resultaten.
Rätt från skogsbruket: En fallstudie enligt DMAIC vid Sveaskog
Människan står inför en rad olika miljöproblem och skogen spelar en central roll som ett hållbart alternativ. Detta ställer i sin tur krav på skogsindustrin att leverera produkter till konkurrenskraftiga priser. För att göra skogsindustrins produkter attraktiva krävs ett starkt skogsbruk som kan tillgodose industrin med de råvaror den behöver i form av timmer och massaved. Sågverken är idag utsatta av hård global konkurrens och har därigenom behövt anpassa och effektivisera sin produktion vilket således ställt nya krav på skogsbruket. Skogsbruket klarar i dagsläget inte av att fullt nå sågverkens längdkrav på grund av en alltför stor längdvariation på kapade stockar.
Ligghall för utegångsdjur ? en sammanställning och analys av domar i djurskyddsärenden som handlar om ligghall till utegångsdjur åren 2007-2013
There is currently an ongoing discussion in Sweden about the need for weather shelter for farm animals being kept outdoors during the winter season. Currently, the national animal welfare legislation requires weather shelter providing the animals? with access to a dry and clean place to rest, but under certain conditions exemptions can be granted. The Swedish Board of Agriculture has put forward a hypothesis that there is a difference between judicial decisions in animal welfare cases dealing with weather shelters, as to whether the animal has shown to be suffering or not. The aim of the study was to highlight any weaknesses or difficulties when assessing animal welfare issues associated to the absence of or design of weather shelters.
Use of feline TK1 as a biomarker in disease monitoring
Serum thymidine kinase 1 (TK1) activity is used as a tumor marker in disease monitoring in veterinary and human medicine. TK1, an intracellular enzyme, is involved in a salvage pathway of DNA precursor synthesis.
TK1 is used in DNA precursor production by catalyzing the transfer of the gamma-phosphate-group from a phosphate-donor to the 5?- hydroxyl-group of thymidine forming thymidine-monophosphate. Nucleoside monophosphosphates are finally converted into thymidine-triphosphates. TK1 activity significantly rises in the G1 and the S phase of the cell cycle.
Påverkar järninjektioner risken för ledinflammationer hos smågrisar? :
Hemoglobin is built up from protein and heme groups which give the blood its red colour . Hemoglobin transports oxygen and carbon dioxide between the lungs and other tissues in the body. Normally, a piglet has a hemoglobin value of 130-150 gram per liter blood, and the lower limit before anaemia appears is 80 grams per liter blood. The immune defense is also dependent upon the presence of iron in hemoglobin, since iron participates in different enzyme systems. When the piglet develops anaemia, it becomes pale and thicker around the neck.
Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :
Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization.
It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared.
During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.
RURIX - ny mätmetod och nytt mått för befolkningstäthet och tillgänglighet : utvecklad och utvärderad med GIS och nätverksanalys
En svår och ständigt aktuell fråga är hur landsbygd och glesbygd ska definieras och avgränsas. För att utföra sådana avgränsningar har en stor mängd olika definitioner och mätmetoder tagits fram. Problemet med många av dem är att de ger mycket grova och statiska indelningar och att de ibland bygger på subjektiva eller svårpreciserade kriterier. Samhällsstrukturen har förändrats, exempelvis är tillgången till bil stor idag vilket ökar tillgängligheten och tillåter att människor bosätter sig längre från arbete och service. Det i sin tur bidrar till att gränsen mellan landsbygd och tätort suddas ut och blir mer diffus.
WIKILEAKS; en spark i rumpan för journalistiken? : Svenska journalister och Wikileaks
Wikileaks is using the new technical solutions to mount big leaks, consisting of secret or sensitive information from the government, institutions and business. This might profoundly change the media reality and it certainly means both new opportunities and new challenges for traditional media; the conditions for the journalists, the sources and the news reporting are changing. In this thesis the relationship between Swedish journalists and Wikileaks has been the focus; they both affect each other but the conditions for this relationship is not yet clear. Clearly there is an interdependence, but who really is dependent on the other and to which degree they are dependent on each other is still a question without a given answer.The aim of this thesis has been to discern a new journalism, and how this responds to the theories of Public Journalism and Journalistik 3.0. The main aim has been to examine what Swedish journalist thinks about Wikileaks, what their attitude towards Wikileaks are, if and how they think that Wikileaks have affected the Swedish journalism.
