This report is an assessment of the feasibility of using aerial photographs to estimate number of stems per hectare in young forest stands, used together with upper height to determine the need for pre-commercial thinning or ordinary thinning cutting. Aerial photo-interpretation was conducted in 2007 on assignment of Stora Enso Skog AB. A mean height function based on stand age produced with data from Bergvik Skog AB?s 2006 forest inventory assessment was used as a proxy for upper height and used together with photo-interpreted number of stems per hectare to determine the need for thinning cutting according to Bergvik Skog AB?s definitions. The test area is located north of Falun on Bergvik Skog AB?s land.Flight altitude was approximately 900 m above ground and the aerial photos were taken by L&L Flygbildteknik AB.

Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s.s. (Fr.) Bref.) and the S-type (Heterobasidion parviporum Niemelä & Korhonen). Therefore a lot of research has been carried out in this topic to find a solution and reduce this problem, one alternative that have shown to be profitable is stump treatment in thinnings.

Bringing back the nutrients from the city to the country is becoming increasingly important, as the world?s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden today. Sewage sludge may contain large amounts of pathogens, such as Campylobacter and Salmonella, why use can cause severe spreading of infections, both to animals and humans. These pathogens have the ability to survive for a long time in soil and water and therefore some sort of treatment of the sludge is recommended before use.

In theory, the logic behind partnerships is simple: All organisations have strengths, but no organisation has all the strength required to do everything. Triggered by global perspectives and challenged by sustainability objectives, the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992 pointed out needs for corporate responsibility. In this conference, Private-public partnership, PPP, was identified as a potential way to work towards sustainability, especially as a way to emphasize a corporate responsibility commitment. Nowadays, organizations exist to satisfy the needs and interests of all their stakeholders, such as customers, markets, shareholders, as well as secondary stakeholders such as media, NGOs, and society at large. Addressing all stakeholders and working towards a sustainable business development makes PPP a potential solution, but also a source of challenges.

The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.

International Marine Group, IMG AB, was established in year 2000, and became the parent company of the three sister companies, Momec AB, Isolamin AB and Premec AB. The IMG ? group supplies complete marine/offshore interior accommodation and tailor-made system supplies to the Building/Industrial sector. With a starting point to develop IMG AB?s logistic and distribution the company has decided to survey the present logistic at their subsidiaries, mainly concentrated on the goods for delivery.

In June 2013 a debate concerning the consumers? right to a label of origin on food packages was held in the Swedish parliament (www, Riksdagen, 2014). The debate was sparked by some food scandals where labelling was falsely used, claiming something that was not true ? the horse-meat scandal, frozen strawberries infected by Hepatitis A, pork sold as beef, etc. These cases were not only wrong in terms of food safety, but also fraudulent and threating consumers? right to fair origin labelling.

Syftet med studien har varit att dekonstruera FN:s förståelse av hot över tid för att diskutera organisationens möjligheter att bekämpa dessa hot i relation till de förväntningar som FN har och har haft på framtiden. Det analysen har visat är att hoten mot internationell fred och säkerhet inte längre konstrueras som dispyter eller konflikter mellan nationer. Istället är det ekonomiska hot, hot mot global goods, internationell terrorism, spridningen av massförstörelsevapen och individer i nöd som Ban Ki-moon konstruerar som hotbilder mot internationell fred och säkerhet, det vill säga det FN syftar till att motverka.Lösningen har alltid varit att hot emot internationell fred och säkerhet ska lösas inom ramen för FN, men själva lösningen har skiftat i karaktär. Från att FN kan ses som en arena där nationer får möjlighet till samtal, till att FN ska verka som en neutral eller oberoende aktör, och slutligen att FN ska ta ledarskapet genom att hantera hoten genom organisationens komparativa fördelar och ingå partnerskap med både statliga och icke-statliga aktörer för att bekämpa hoten. Vilket analysen visar då de aktörer som är involverade för att åstadkomma internationell fred och säkerhet har förändrats över tid.

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

The interest for locally produced food is increasing due to consumer concern about the environment, distrust of industrial foods and a demand for high quality products. Apple is the predominant fruit crop in Sweden, and by processing apples into cider and vinegar, these products could significantly contribute to the development of the market of local foods.In this study different yeast types and different bacterial cultures were evaluated for their suitability in cider and vinegar production from cloudy apple juice. Ten apple cultivars (Aroma, Baldwin, Belle de Boskoop, Bramley, Cortland, Gravensteiner, Ingrid-Marie, Jonathan, Rubinola and Spartan) were also evaluated for their suitability for production of juice, cider and vinegar. Chemical analyses including total soluble solids, titratable acidity and total phenols were performed on the products along with sensorial evaluation by taste panels.The yeast strains were shown to have an effect on fermentation rate and the resulting content of total phenols in ciders fermented from cloudy apple juice. Dry commercial starter strains gave a higher appreciated cider compared to cider that was spontaneously fermented, and the ale yeast Safale S-04 was concluded to be the most suited for fermentation of cloudy apple juice.For vinegar production, the bacterial culture had an effect on TSS, but not on any other chemical or taste characteristics.

Digitala läromedel blir ett vanligare inslag i skolgången då ny teknologi erbjuder tidigare okända pedagogiska möjligheter. Denna uppsats undersöker hur elever som använder ett digitalt läromedel i form av en virtuell lärmiljö för matematiklärande upplever denna lärmiljö. Dessutom undersöks elevernas prestation i lärmiljöns matematiska uppgifter. Skillnader mellan elever i olika årskurser samt elever som är matematiskt låg- eller högpresterande studeras. Matematisk prestation beskrivs utifrån Goods (1981) passivitetsmodell som innebär att lågpresterande elever är mindre risktagande i klassrumsmiljön.Elevernas upplevelse av digitala läromedel studerades i en virtuell lärmiljö bestående av två moduler, en spelmodul och en modul för skriven dialog.

Under ett samarbete med underklädesbutiken Bornevings har information om textila materialtagits fram. Butiken erbjuder alltid god service när det gäller utprovning av plagg men saknarbaskunskaper om textila material och hur de tillverkas. Textil informationen har tagits framför att underlätta detta problem. Kunskapsbristen kommer nu att eliminerats så personalen kanerbjuda den bästa servicen.För att få reda på hur informationen på bästa sätt skulle redovisas för butiken studeradespedagogik. Inlärning fungerar olika för alla, vissa tar till sig bilder medan andra lättare kanregistrera text.

About 80 % of all Swedish dairy cows are kept in tie-stalls, but loose housing is increasing, probably because it is more profitable for the farmer. The design of the floors is of cruicial importance to the cows well-being. Traditionally, the most common type of floor in the alleys of a cubicle system still is a slatted manure-draining floor made of concrete. The typical Swedish design has 125-mm slats and 40-mm slots, maximally. With too wide slots, there is an increased risk of injuries to the claws when the cow makes a hasty move.

In our globalized society massconsumption is widespread. However there is a trend showingthat people are starting to re-use clothes instead of buying newly produced garments. Reasonsfor buying secondhand clothing are many. During the 1950s people strived to look likeeveryone else but in the 1960s this changed. Subcultures grew stronger.
