In Europe poplar plantations has been planted for more than one hundred years. In the first plantation was made in 1940. The interest for poplars has since then shifted over the years and has for long periods been very low but is now slowly increasing again. The main reasons why poplars are becoming more interesting are because of their great production potential. Nevertheless, the knowledge of how to mange poplars in Sweden are very low and very little research has been done concerning management of the species. The objective for this study was to; 1) investigate and document experience and results obtained in practical Swedish forestry, 2) to give a fair picture of the perceived advantages and disadvantages that the poplars has for the forestry, 3) document what the foresters that has experience and those who has no experience of poplar plantations thinks about the potential of poplars.

Syftet med studien är att öka vår förståelse för hur slöserier påverkar ett internt material och produktionsflöde i en producerande verksamhet, för att kunna ge förslag på effektiviseringar av denna process. Studien är utförd på företaget Växjöfabriken Produktions AB som är beläget i Växjö och utför skärande bearbetning på gjutgods. Efter att ha studerat befintliga teorier skapade vi vår teoretiska utgångspunkt med det urval av teorier som vi ansåg vara viktiga för studien. Från dessa genererade vi en analysmodell som sedan låg till grund för det fortsatta arbetet. Analysmodellen gav ett strukturerat arbetssätt för att samla in empirisk fakta från företaget som vi sedan använde för att göra en analyserande jämförelse med vår teoretiska utgångspunkt.

The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.

The biodiversity of the Swedish forest has degenerated since the beginning of the 19th century when fire suppression and large scale logging first occurred. Together with a changed land use, these actions today have had a negative influence on many forest dwelling species, due to gradual reduction of natural processes, successions and different structures from the forest ecosystem. The Swedish Forest Act, together with different environment certifications, have today encouraged private persons and forest companies, among them Holmen Skog, to work actively to improve nature conservation. The aim of this study was to, by field inventories of already existing nature values, literature studies, recommendations from scientific reports and ecological gap analysis as a basis, make a management plan, for a non-production area, to conserve or improve the prerequisites for biodiversity. ?Storskogsberget? is located in the coastal area of Västerbotten County, 35 km from the city of Umeå.

Bakgrund: De flesta inomhusbadanläggningar är idag 30-60 år gamla och många anläggningar har stora problem med skador på både byggnader och bassänger. Skadorna är ofta så pass allvarliga att det inte längre är lönsamt att renovera utan på många platser planerar man att bygga nya bad. För att undvika framtida problem är det viktigt att dra lärdom av vilka skador och problem som har inträffat samt hur man vid nybyggnation och renovering ska kunna undvika dem. Vid byggande av dagens inomhusbadanläggningar tillämpas främst tidigare branscherfarenheter. Det faktum att så stora brister och omfattande problem förekommer, tyder på att kunskapen är otillräcklig.

SyfteSyftet med studien är att undersöka hur projektledare självskattar sitt ledarskap och projektmedlemmar upplever motivation i pre-development projekt på Karolinska Universitetssjukhuset och Scania.MetodStudien är kvantitativ och deduktiv. För att undersöka förekomst av transformellt ledarskap hos projektledare och inre motivation hos projektmedlemmar har vi valt att använda två frågeformulär, Multifactor Leadership Questionnaire Leader Form respektive Work Preference Inventory. Båda formulären är undersökta av forskare vad gäller validitet och reliabilitet.ResultatResultatet i vår undersökning visade att projektledare på Karolinska hade en högre förekomst av transformellt ledarskap än de på Scania. I båda organisationerna fanns även transaktionellt ledarskap i ganska stor utsträckning medan förekomsten av passivt undvikande ledarskap var lägre. I analysen av underfaktorerna i MLQ Leader Form (5x-Short) visade våra data för transformellt ledarskap att idealiserade inflytandet och intellektuell stimulans låg högre på Karolinska.

Today, there are few industries left in our cities. Industrial areas thatare located in urban settings close to water or city centers are oftenreplaced by housing. In my thesis I want to explore how such industrialsite located in an urban setting can be transformed into anindustrial park where the industrial structures are saved. By approachingthis type of environment in a positive manner, I wish tohighlight the potential aesthetic and functional value in the existingindustrial structure. Through the transformation and design of anexisting industrial site I will convey the previous use and history ofthe place.The wastewater treatment plant, Kungsängsverket, is located in thedistrict of Kungsängen in the southern part of Uppsala.

Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last 50 years, with clear-cuts, have contributed to a fragmented forest landscape.

Outdoor advertising is not very often discussed within city planning even though the commercial messages occupy much of public space. The advertising signs affects not only the physical environment but also social life. In this report I would like to acknowledge and question the presence of advertising in our everyday environment. Outdoor advertising is not a new phenomena, technical progress however, results constantly in new expansions in the environment. Today advertising occurs in all sorts of shapes in the cities, both as free standing signs and as signs attached to facades, incorporated in city furniture such as bus shelters and on vehicles moving along the city streets. Grouping advertising into two categories; local and national, reveals that the different categories have different impact on public space.

In the tropics, logging and wild fire can result in degraded secondary forests with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. However, there is a lack of knowledge concerning the ecology of tropical tree species and further studies would be advantageous for future rehabilitation efforts of degraded rainforest. The objective of this study was to investigate how mother trees in secondary forest and different site factors affect the abundance and spatial distribution of natural regeneration of non-pioneer tree species in a tropical rainforest in Sabah, Malaysia. The study took place in the INIKEA Forest Rehabilitation Project area, which suffered from wild fire in 1983 and has been selectively logged over both before and after the fire. Natural regeneration and site variables were inventoried in plots, while mother trees were inventoried in the whole survey area.

This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.

Sammanfattning Ensilerat vallfoder är ett av de absolut viktigaste fodermedlen för att förmå korna att producera en stor mängd högkvalitativ mjölk. En hake är dock att ensilaget ska vara av god kvalitet och med bästa möjliga näringsvärde, samtidigt som man även vill ha volymmängder. För att få detta gäller det att skörda vid rätt tidpunkt, vilket kan vara svårt att veta när det infaller. Till detta finns ett hjälpmedel som kallas skördetidsprognos. Detta går ut på att man klipper prover i vallen upp till tre gånger innan första skörden för att analysera gräset och därigenom kunna avgöra när bästa tiden är för att skörda för att få den mest optimala kombinationen av mängd och näringsvärde. Syftet med detta arbete är att undersöka hur bra hjälpmedel jordbrukare i norra Sverige tycker att skördetidsprognosen är för att få en ökad kvalitet på ensilaget, samt att jämföra variationen i näringsvärde och mängd biomassa inom och mellan olika fält.

Holmen Paper is one of Sweden?s leading manufacturer of paper, with two Swedish production facilities located in Norrköping and Hallstavik. The European continent constitutes the company?s largest customer base which makes the company?s distribution system an integral part of the business. Historically, much of the produced paper has been transported by vessels, as vessels allow large volumes of goods and deliveries to markets which are difficult to reach with other modes of transportation.

The development of our time, is due to great progresses in technology and an enormous ex-plosion of knowledge, has lead to an increased effort of our attention as a result of a boundless torrent of information . Higher productivity and efficiency in our workplaces and homes crea-tes fewer opportunities for rest, leading to a community where stress has become a national disease. Recreation is an important part of our lives in order to be able to deal with stress and is now considered to be an essential resource when it comes to sustainable development. Green spaces are therefore today viewed to play a considerable roll for the national health. Nature has proven to have positive influence on man which leads to a decrease in blood pressure, an increase in power of concentration and lowered production of stress hormones.

The following thesis is a study of the forest history on the island of Ängsön-Marskär concentrating on the last three hundred years. The island is located in the administrative province of Stockholm, the local community of Haninge and it is situated approximately seven kilometres east of the island Ornö in the south of the Stockholm archipelago. The questions this thesis attempts to answer are: How where the natural resources on Ängsön-Marskär used through the centuries? How has the state of the forests developed since the 16th century? How will the nature develop onwards? The thesis is based on archival sources for Ängsön-Marskär and the surrounding areas. A field study was conducted where the entire island was investigated using an objective forest inventory method. The first map material existing over Ängsön-Marskär is from the year 1711.
