Interdependence between seed age and aerated steam treatment intensities
Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities.
Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.
Återvinning av industriell restvärme som värdeskapande process : En fallstudie på SSAB EMEA i Borlänge
The industrial sector accounts for a large share of greenhouse gas emissions. To reduce its negative impact on the environment is crucial in the quest for a sustainable future. In discussions of the industrial sector's impact on the environment guidelines have been highlighted as a tool to assist the industries in their efforts to change the relationship between the consumption of energy and production. This by improving energy efficiency and a shift to the best available technology. During the past 30 years the steel industry has reduced its energy consumption per ton of steel produced by 50 percent.
Du tysta, ej glädjerika sköna. Betydelsen av kommunikationsutbildning för att utbilda bättre ledare.
Every year, reports are published that shows how universities fail to meet the demand from companies who are looking to hire students with solid communication skills. At the same time, the importance of communication for effective leadership is constantly increasing. Today, many business schools around the world states that they strive to educate future business leaders and have therefore realized the importance of teaching the skills of communications to its students. The majority of Swedish business schools, however, have not yet made communications an essential part of their curricula. This indicates that most business students in Sweden today, do not receive the toolkit needed to take on leadership roles.

Spridning av släckvattenpartiklar : En studie på spridning av partiklar genererade från brand
During a fire large amounts of particles and unhealthy agents occur. Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.
Innovationskommunikation i börsnoterade företags årsredovisningar: En fallstudie av Europeiska IT-företag
IT-branschen karakteriseras av snabb teknisk utveckling och kräver externt finansiellt kapital för att driva forsknings- och utvecklingsverksamheten. För att innovativa IT-företag ska lyckas få tillgång till extern finansiering är transparens angående innovationsverksamheten i årsredovisningen av stor betydelse. På grund av hög konkurrens på marknaden uppstår dilemmat att hitta rätt balans mellan transparens och sekretess i årsredovisningen. Företaget behöver uppnå transparens för att minska informationsasymmetrin mellan företaget och dess investerare för att få tillgång till externt kapital, men samtidigt kan detta också utnyttjas av konkurrenterna vilket kan försvaga företagens konkurrensfördelar. Årsredovisningen är en av de viktigaste kanalerna för kommunikation av innovationsinformation till investerare.Syftet med denna studie är att öka förståelsen för kommunikation av innovationer i extern redovisningsinformation avsedd att minska informationsasymmetri hos företag med hög- respektive låg barriär mot imitation genom att (1) beskriva kommunikation av signaler om innovation i börsnoterade innovativa företags årsredovisningar och (2) identifiera och analysera signaleringens betoning och karakteristik (3) samt att utveckla en modell för signalering av innovation förhantering av informationsasymmetri.
Barkar det åt skogen för svenskt tidningspapper? : empirisk analys av efterfrågan och företagsstrategier på den svenska marknaden
According to Food and Agriculture Organization newsprint is defined as: Uncoated paper, unsized (or only slightly sized), containing at least 60 percent of mechanical wood pulp. The consumption of newsprint in Sweden was just over 798 000 tonnes in 2009, which represents approximately 90 kg per person. Although there are studies that predict a drastic reduction in newsprint consumption in the Western world, there seems to be a clear difference between forecasts for the future given by statistical analysis of newsprint consumption and forecasts given by experts in the industry. The former predict a continuing increase while the experts see a coming decrease in consumption.In this report, both demand and business strategies of newsprint in Sweden are studied. The study also presents a forecast of the future which is based on historical data and qualitative interviews.
Kostnader vid gallring med flerträdshanterande aggregat, från skog till industri
Profit in first commercial thinnings of today is hard to achieve. This is because of prevailing pulpwood prices and because of high costs of logging and transport. To reduce these costs higher productivity is advocated. One way to increase the productivity is the use of multi-tree handling harvester heads. The aim of this study was to calculate logging and transport costs in first thinnings, where multi-tree handling has been used.
Identifiering av konfliktbestånd med hjälp av laserskanning
The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.
Ägarlägenheter : en jämförelse mellan omvandling av hyresrätt till ägarlägenhet och ombildning av hyresrätt till bostadsrätt
Bakgrund och problem: Konsultbranschen kännetecknas av en hög omsättning av aktörer. En anledning till att det ständigt alstras nya mindre aktörer till branschen är att den kan vara lukrativ med låga inträdesbarriärer. Men varför försvinner många aktörer lika fort som de kommer upp? Är det en brist på strategi och styrverktyg som ligger till grund för problemet? Kan det bero på svårigheten för småföretag att skapa sig en solid varumärkeslegitimitet, och finns det en möjligt att med hjälp av styrverktyg stärka företagets varumärkeslegitimitet? Fallföretaget som använts i den här studien är ett litet konsultföretag som vill stärka varumärkeslegitimiteten med hjälp av differentieringsstrategi på marknaden.Syfte: Syftet med den här studien är att med hjälp av en egenarbetad utvärderingsmodell utvärdera olika långsiktiga styrverktyg inriktade mot små konsult- och tjänsteföretags. Genom att utvärdera för- och nackdelar för tre utvalda styrverktyg och sedan applicera de på ett litet konsultföretag är förhoppningen att studien kan leda fram till rekommendationer gällande styrverktygens nytta och möjlighet till anpassning.Metod: I metodavsnittet förklaras vilka metodiska val som har använts i studien.
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.
Minskad trädtillväxt under Lilla sitiden? : En dendroklimatologisk jämförelse mellan nutid och 1600-talet invid trädgränsen i norra Skandinavien
During the period called Little Ice Age (1400 ~ 1900) the climate of northern Europe was in an annual year-basis overall colder than it was before and after that period. The numbers of short, cold and rainy summers and long, bitter-cold winters where often repetitive under the approximately 500-years the period lasted. In Scandinavia, the coldest time during this period is estimated to have started around the end of the 16th century and lasted to the beginning of the 18th century. Trees growing at the tree-line are limited by temperature for their annual growth and hence showing differences of growth during changes in the climate, a method called dendroclimatology. The variations of growth can be read in the tree-rings either by analyze the width of the ring or by look into the density of the wood and is used to reconstruct past climates.
Kvalitetsarbete i grotskotning
This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.
Flerskiktat papper : en sammanställning av historia, teknik och forskningsresultat
Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.
Språk- och kulturella barriärer i mötet mellan dietist och patient : En kvalitativ studie ur ett dietistperspektiv
Bakgrund: I Sverige ökar immigrationen för varje år; därmed söker sig fler individer som härstammar från andra länder och kulturer till den svenska sjukvården. Sverige har lagstiftat att hälso- och sjukvårdspersonal skall ge varje individ likvärdig sjukvård.Kommunikation utgör en viktig del i kontakten mellan patient och hälso- och sjukvårdspersonal. Språk- och kulturella barriärer kan leda till bristande sjukvård för patienten. Detta medför att sjukvårdspersonal kan uppleva att de gör ett sämre jobb vilket kan leda till frustration.Syfte: Syftet med studien var att belysa och utforska dietisters upplevelser av språk- och kulturella barriärer vid mötet med patienter med annat modersmål än svenska.Metod: Utifrån en kvalitativ forskningsmetod intervjuades sex kliniska dietister. Vid intervjuerna användes en semistrukturerad frågeguide.
