Nutrient effects on microorganism communities in nutrient poor soils
Better, more efficient fertilizers with great productivity and economic returns are needed, but it is important today to find fertilizers that are also sustainable. It is also important to carefully monitor their impact on the environment, including potential side-effects. In this context, the microbial communities that carry out numerous essential functions contributing to a functional ecosystem are of particular interest.
The present study is a complement to a pot experiment that investigated the potential of different waste products for use as fertilizers and how they affect the microbial community. In the pot experiment, the clearest treatment change in microorganism community function was found in the fully fertilized treatment used as a positive control. The question was whether this was indirect, i.e.
Det queera Japan: Genusföreställningar och normbrytande konst i det samtida Japan
This paper discusses some concerns about Japanese gender identity as a construct and the subversive means to overthrow it. In my paper I claim that the eastern influences on Japan has created a gap between old and new gender- traditions and norms. This interspace is what the philosopher Judith Butler claims as the site for a possible gender transformation. As Butler claims gender identity to be a construct, I use her methods of understanding and subsequently queertheory, to investigate the construct of Japanese gender identity and also the norms that constitute a national identity. As I elaborate on this theory I use specific artworks from Morimura Yasumasa, Yoshiko Shimada and Bubu de la Madeleine and also the all-male theatre kabuki vs.
GPS- & GIS-användning i drivningsprocessen hos Stora Enso SKog AB :
GPS (Global Positioning system) and GIS (Geographical information system) has been used for planning and inventory in the forest sector for more than ten years. The last years the development has come to equip harvesters and forwarders with GPS and GIS (GIT).
The goal with this study was to reach a basis for decision, how Stora Enso Skog should continue its investment in GPS and GIS in harvesters and forwarders. To reach this basis for decision, possible advantages and benefits, disadvantages and problems in the harvesting process was evaluated. The study was made as an interview study with four harvesting managers and ten machine teams. To secure the quality of the results an interview questionnaire was made before the interviews were done.
The results showed that GIT will make the harvesting managers work easier.
Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd
Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT.
The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.
VÄRDEFLÖDESANALYS AV PW1000G 30k TEC
The thesis work has been carried out at Volvo Aero Corporation (VAC) in Trollhättan. VAC has entered a partnership as developing and producing partner with engine manufacturer Pratt & Whitney and is currently at the starting phase of producing the turbine rear frame (TEC) to the engine PW1000.The purpose of this study was to create a report on process level that describes the conditions and the potential with PW1000 TEC to reach the product cost calculation taking into account lead times and describe alternative method solutions.The report describes a comparison between the present flow (2012), a flow based on product cost calculation (2016) and a potential flow (2016). The work has mainly been based on acquiring the knowledge and information available to inspect the present flow; this has been done by workshop observations, meetings and gathering of the information that is available on the work site for the PW1000 TEC.The information obtained has been merged into an Excel document, called Roadmap. It serves as a roadmap with current situation as the start and the potential flow for 2016 as the goal. With the roadmap as a tool, assumptions have been taken considering the flow and how it will change, where processes have been eliminated, reduced or marked as a problem..
Nätverk på nätet: Innovativt värdeskapande genom samarbete
A constantly increasing number of magazines are using the Internet as a business channel. One of these is Allt om Mat (All about Food). Together with expressen.se, Allt om Mat developed a food website, alltommat.se, which was introduced at the beginning of 2008. In this essay we investigate how alltommat.se developed its service concept. Further, we look at how this development has influenced and been influenced by relations among the three actors and the users.
Proxyserver för passiv informationssökning
In today?s society the average person is flooded by information from everywhere. This is in particular the case when using the Internet; consider for a moment the fact that a decent search engine at this moment scans 8 058 million homepages. For a user that repeatedly comes back to the same site, the case is often that they know what they are looking for. The problem is to isolate the important information from all the other information embedding it.We would like to state that we have found one possible solution to this problem, where the user himself can define what information he is looking for at a specific server, then scan the server when visiting it with his browser.
Heliga sopor : skärvstenshögen utifrån ett polynesiskt perspektiv
In Scandinavia the general idea of the Bronze Age society is that it was organised as chiefdoms. The model for what they looked like is taken from the anthropological studies of the Polynesian chiefdoms. The aim of my study is to investigate a Scandinavian Bronze Age feature, known as cairns mainly containing fire-cracked stone. This is compared with how people in different Polynesian chiefdoms, looked at similar remain. This is done to get a background for new ways of interpretation of such remains.
Elektrifiering av jordbruksmaskin : Direktkoppling till solföljare och elnät
The agricultural sector is currently highly dependent on fossil fuels, with diesel beingmost prominent. There are however both historical and modern alternatives thathave not been subject to enough evaluation to disregard them as suitable alternative.This report aims to theoretically investigate the feasibility of converting aconventional diesel driven tractor to run on electricity, delivered via a cableconnected to either the main power grid or on-site electric production, such asphotovoltaic. Delivering electricity to the machine via a cable is a method withhistorical roots in the early 20th century and in the present day mining industry.The economic and technological potential of the technique are evaluated, along withthe examination of several different motor powers, voltages, losses and constructionideas. The report finds the technique to be both possible as well as long termeconomically and environmentally beneficial. To realise this method however, somedeviations from the present methods of agricultural farming must be made,considering the more advanced driving patterns, the limited mobility and therequirement for extra driver awareness.
Gömt bakom symbolen : en studie om gropkeramisk dekor på Gotland
This thesis analyses the decoration on the pots of the Pitted Ware Culture on Gotland. The pottery from this period is richly decorated with various ornaments, the most common are the pits but other types of decoration occur. The purpose of this study is to get an insight into what the patterns meant to the people that made and used them and what role these may have played in their lives. The author will analyse the decoration on potsherds found from the three Pitted Ware sites of Visby, Ajvide and Hemmor on Gotland. This will be used in a comparative analysis to investigate if differences and/or similarities of the pattern occur between and among the sites.
Adaptive Charging System : Anpassningsbart laddningssystem för elbilar
This is a master thesis from Uppsala University in collaboration with B Locket AB (more known as www.blocket.se). B Locket AB is a large ad-company from Sweden, located in Stockholm.Search engines on the market today are becoming more and more complex. When they were first introduced, they only had one function and that was to produce search results containing the string that the user had typed. Today, users want it to be able to spellcheck, produce more results and sort search results on specific fields as well. Preferably, all these features should not affect the performance as a whole.The reason to why these demands have come up is that users are getting more and more used to internet services as a whole and they want everything to be as easy as possible.The user ability has become a substantially more important area in the computer industry and this needs to be taken into account when it comes to B Locket AB and its search engine.
BIM-PROJEKTERING FÖRFÖRBÄTTRAD LOGISTIK
The construction industry depends on functioning logistics; if the logistics isn?tworking the construction site will risk to be interrupted due to material shortages orproblems with deliveries. Despite this, the construction industry is battling logisticproblems daily. This problem is very time consuming and costly for the companies.These theses are written for Peab Bostadsproduktion and investigate if it is possibleto focus on logistics earlier in the building planning process to reduce the problemsthat occur. Peab has partnerships with three companies that could be helpful for themin the work of reducing logistic problems.
Utstationering av utländska arbetstagare i Sverige : Är Lex Britannia och Sveriges sätt att implementera utstationeringsdirektivet (96/71/EG) förenliga med EG-rätten?
The Latvian building company Laval un Partneri Ltd (Laval) posted Latvian construction workers at the rebuilding of a school in Vaxholm in autumn 2004. Because the company refused to sign a collective agreement with Svenska Byggnadsarbetareförbundet (Byggnads), which is the Swedish trade union for constructions workers, Byggnads put the construction site under a boycott. Next Laval sued Byggnads for damages in the Swedish Labour Court (AD) because Laval considers the boycott as well as Byggnad´s demand that Laval signs a collective agreement incompatible with EC Law. AD has now demanded a preliminary ruling from the European Court of Justice (ECJ). While waiting for the preliminary ruling from the ECJ, several important questions of principle stand unanswered.

10 000 nya invånare till Luleå! : En studie om en kommuns platsmarknadsföring i sociala medier
Today, nine out of ten municipalities are active on social media and it has become increasingly popular among municipalities that make use of placemarketing to promote their particular region. A problem that is raised in this study is that the population of the municipalities in northern Sweden often is in decline. The purpose of this study is to investigate how a democratic-controlled organization such as Luleå Municipality uses the social media Facebook in its placemarketing, to highlight a place of scale and to attract new residents and stakeholders to move to or visit the city. In order to answer the purpose I have with the help of a critical discourse analysis examined how Luleå Municipality using social media Facebook in their marketing of Luleå as a place. The results were then analyzed using theories of placemarketing, Norrland and the market-oriented municipality.
