The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties. This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

Stockholmsregionen växer och utvecklas i hög takt. Bostadsbristen är ett faktum när fler ochfler vill bo i en urban miljö, dessutom ställer detta högre krav på att regionenslogistikförsörjning hanteras korrekt. Mot denna bakgrund uppstår konkurrens kringmarkanvändningen i citynära verksamhetsområden. Idag omvandlas verksamhetsområden tillattraktiva bostadsområden, exempelvis Liljeholmskajen och Norra Djurgårdsstaden. Syftet medrapporten är att undersöka möjligheten att omvandla tre verksamhetsområden (Lunda,Slakthusområdet och Västberga) och vilka regleringar samt investeringar som är nödvändigaför att verksamheterna ska kunna omlokaliseras till perifera verksamhetsområden i regionen.Första steget till omvandling är att omlokalisera den befintliga verksamheten, som i de angivnaområdena klassificeras som logistikintensiv, till perifera verksamhetsområden i regionen.Logistikintensiv verksamhet karaktäriseras av att transporter till och från fastigheten ärnödvändiga för verksamhetens framgång, det kan vara allt från ett tryckeri till en globaltransportör.

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

The pig is unique in the way that it gives birth to a large number of newborns in each litter. Because of this the sow has developed a special behaviour during suckling to ensure that not only a part of the litter gets all the milk. Milk is only available during milk letdown. The piglets have to massage the udder for a long time before letdown and the more piglets at the udder the sooner the milk comes. The sow has developed a special grunting pattern to let the piglets know when she is ready for suckling and to signal milk letdown. Our aim with this study was to investigate if sows have individual grunting patterns repeated over time. We also wanted to know if sows with a more distinct grunting pattern have better growth in their litters.

Travelling by train has increased during the last decades in Sweden. This has put pressure on the existing infrastructure and has created problems with delays and cancelled departures. The railway is a complex system with mutual dependencies and high vulnerability for disruptions. The situation for the railway system in the Stockholm region is today strained. The capacity is fully used.

I have studied how human networks can affect decision-making and different constellations. The primary purpose is to clarify the possibility to affect the decision to move the infrastructure investments from Region Skåne to Region Västra Götaland. The study starts at the EU-level and continues to the Government and on to the region. Region Skåne is studied especially since it was from there the infrastructure investments were moved.The conclusion is that there is no specific representation in the government that represents regional topics, in spite of the fact that almost 30% of the members of the Parliament come from these regions. There is no discussion between the members that could be considered a networking-activity beneficial for the regions.

Uppsatsens syfte är att öka kunskapen om de faktorer som bestämmer efterfrågan på lokal och regional kollektivtrafik. För att uppfylla syftet estimeras efterfrågemodeller med hjälp av data från Linköpings tätortstrafik och Sveriges länstrafikbolag. Modellerna formuleras med utgångspunkt från ekonomisk teori och tidigare studier innom området. Bland annat konstateras att resenärens tid är en viktig produktionsfaktor vid produktion av transporttjänster. I modellerna som formuleras förklaras resandet med den monetära avgiften för en resa, realinkomst, bilinnehav per person, petroleumpris och utbudskilometer per innevånare.

In this paper I argue that the development of innovation ideas within the financial system of scientific research might have a counterpart within the financial system of the social sciences and the arts. The ideas of innovation share a common way to evaluate science in terms of how well it can contribute to economic growth. In the past two decades a similar development can be observed within Riksbankens Jubileumsfond (RJ), one of the largest external financiers of the social sciences and the arts in Sweden. The idea of evaluating research used by the innovation ideas has grown popular within RJ, only it seems they evaluate research in terms of how well it fits into an international research community rather than how much it can contribute to economic growth as is the case within the innovation ideas. By examining the different ways of financing research that RJ has used during the last 2 decades, this paper aims to introduce a new perspective in which it is possible to understand the development within this type research funding as a part of a bigger system of development..

This thesis has been made on behalf of SCA Skog AB to assess the need of boron in Swedishforest fertilization. Boron has been added to Swedish forest fertilizers since the beginning of the1980s. This makes the fertilizers more expensive and therefore has the necessity of boron inSwedish forest fertilization been raised.The Swedish bedrock generally contains small amounts of boron. The boron in the bedrock istightly bound to the mineral tourmaline and mostly unavailable for plants. This leads to that thecontribution of boron to the soil from weathering is very low besides soils with marinesediments.

I Sverige är kommunerna ansvariga för planeringen genom det kommunala planmonopolet. I och med att människor blir allt mer rörliga suddas gränserna också ut allt mer. Kommunerna tvingas ändra sina rutiner och se på exempel, för att lära sig hur planeringen över gränser går till. Flera faktorer och aktörer på lokal, regional, och nationell nivå påverkar hur den regionala planeringen ser ut.I landskapssammanhang är det en nödvändighet att planera över gränser, och efterfrågan av planeringsstrategier över gränser väcker behovet av större regioner, där gemensamma strategier kan ange ramarna.Genom studier av litteratur som tar upp exempel på regionalplanering i olika skalor och definitioner av aktörer och begrepp, ges i den här uppsatsen en bild avhur regional planering fungerar idag. Litteraturen är hämtad från EU?parlament, Sveriges Regering och Riksdag samt både statliga verk och andra organisationer som beskriver sina och andras roller inom planering som försiggår över gränserna..

The proportion of women entrepreneurs in Sweden is, as in many countries, smaller than the proportion of men entrepreneurs. Sweden has therefore created political measures with the ambition to increase women entrepreneurship. However, knowledge about the determinants of women entrepreneurship is needed in order to enable the promotion of it and, at the same time one can question the treatment of women entrepreneurs as a homogenous group. The purpose of this thesis is to investigate the determinants of women entrepreneurship and whether these determinants fluctuate regionally. If this proves to be the case, a more spatial/individual approach should be used, when creating measures to promote entrepreneurship.

Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.

Every plan and program decided on by an authority or municipality, where the environmental impact can be considerable, must be environmentally assessed according to Environmental Code, the Planning and Building Act (PBA) and the Regulation on Environmental Impact Assessment.The purpose of this study is to examine the Environmental Impact Assessment (EIA) for The Region Development Plan for the Stockholm Region, RUFS 2010. The plan was approved by at that time the Regional Planning Office (Regionplanekontoret), which procured the process by consultants. RUFS 2010 includes two merged plans ie. a regional Development Plan (RUP) and the Regional Spatial Plan for Stockholm. It was necessary to establish an environmental assessment of RUP, but not for the regional plan.

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.
