In modern military operations the requirements of transmitting large amounts of information have increased substantially during the last decade. This increases the demand for high-capacity radio networks. It is also very important that military decisions are made on recent and correct information and this implies that low and known delays are required. The existing military radio ommunications, within the Swedish army, do not meet the requirements for capacity and delay. We have investigated how the capacity and average delay can be improved in an Ad Hoc network with STDMA by using antenna arrays.

The goal of this work has been to search historical materials, to identify the park's historical development, to prepare proposals on measures and that work should be the basis for further research. The aim has been to train us in searching for and use of materials and to gain an understanding of the process of work with older plants. In the process we have sought and found materials in archives, through literary and oral sources, and email contacts. Because of its excellent location perched on an islet in the low landscape Näsbyholm was long a fortress. The old castle on Näsbyholm was from the late 1400s but the site was fortified much earlier. The islet was at this time completely surrounded by water and there was a drawbridge over the narrow waterline. The owners are liable since the late 1200s.

Introduktion: Depression, ångest, stress och ätstörningsproblematik har visat sig ha en hög prevalens hos personer som lider av obesitas. Syfte: Att undersöka om och i så fall hur ångest och depression mätt i HADS förändras i en grupp som genomgått överviktskirurgi. Av intresse var också att undersöka om viktnedgång samt om preoperativa symtom på stress, hetsätning och känslomässigt ätande predicerar utfallet av symtom på ångest och depression postoperativt. Metod: 30 patienter som genomgått överviktskirurgi på Akademiska sjukhuset i Uppsala under våren 2011 inkluderades i studien. Dessa patienter hade innan genomgången operation och vid en uppföljning sex månader postoperativt besvarat olika screeningformulär avseende psykiskt välmående, ätstörningar och stress.

Selenium (Se) is an essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px?s), are important as antioxidants and protects against free radicals. The activity of GSH-Px is strongly regulated by Se storage in the liver.

Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.

This paper is a degree project on the C-level, 15 points at University West, Department of Business and IT dept. Informatics. This study is about agile methodology and its impact on IT projects. Requirements management is a process within an IT project, where customer has certain requirements that must be met by an IT system. The difference between the traditional and agile development is in the requirements management process and it can cause problems in a project.

Rapid population growth and the fact that phosphorous is a limited resource implies that the question regarding an efficient use of phosphorus is of great importance, and consequently,that the phosphorous use efficiency should be as high as possible. The view on phosphorous use efficiency, and how this is calculated, has varied over time. This has had great implications on what type of research that has been conducted, which have resulted in an inconsistency between the academic?s view on the subject and recommendations received by farmers. The purpose of this paper is to calculate the phosphorus use efficiency in the Swedish long term fertility experiments.

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.

Bakgrund: Med anledning av Sveriges ökade ekologiska konsumtion så kommer denna uppsats vidare undersöka ekologisk konsumtion som fenomen och hur företag bör arbeta för att på bästa sätt lyckas nå långsiktig överlevnad med just ekologi som grund.Problem: Vilka faktorer är viktiga för företags beslut om marknadsföringsstrategier gällande ekologiska varor, för att nå långsiktig överlevnad?Syfte: Syftet med den här uppsatsen är att analysera och utvärdera konsumentbeteende med avseende på ekologisk konsumtion. Metod: Undersökningen är kvalitativ och kommer att bearbetas utefter en hermeneutisk och systemteoretisk ansats. För att kunna svara till problem och syfte kommer befintliga teorier att användas. Teoretiska perspektiv: Utbytesperspektiv, utvecklingsperspektiv Teorier: Mervärdesteorin, involveringsteorin, marknadsföringsmixen, konsumentbeteende, totalkommunikation, värdekedja och värdestjärna.Empiri: För det empiriska underlaget har sju stycken konsumenter och en branschrepresentant intervjuats.Analys: Empirin har analyserats utefter de faktorer författarna givit som centrala för att svara till problem och syfte. Författarna har efter operationalisering kunnat dela in respondenterna i en matris baserad på involveringsgrad till ekologi. Detta för att göra det enkelt att följa uppsatsens röda tråd.Resultat: Författarna menar att det är involveringsgraden till ekologi, om den är hög, som är avgörande för konsumtion av ekologiska varor.

Sewage sludge contains plant nutrients and has earlier been utilised as fertilizer to cropland. Unfortunately not only plant nutrients but also heavy metals, pathogens and organic contaminants tend to accumulate in sludge. The suitability to use sewage sludge in agriculture has therefore been subject to several discussions over the years. The Swedish food industry does no longer accept sludge as fertiliser for Swedish producers. In 1999 the Swedish parliament accepted several objectives for environmental protection. In order to prevent environmental pollution and further exploitation of the earth crust, one of these objectives confirm that phosphorous from sewage shall be recirculated to arable land.

Considering that the price and demand for energy gradually has risen over the past decade and a wider discussion about the human impact on the environment has become increasingly more important and given a clearer role in modern society. This has contributed to increased incentives to reduce the use of fossil fuels and increase the use of renewable energy.The agriculture currently accounts for 20 % of Sweden's total greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy audit of Wapnö?s existing energy system and how it changes with a future biogas plant in operation. The energy audit is used to illustrate how the company?s climate footprint could change.

The project is carried out in cooperation with the company Kinnarps AB.The objective of this project was to develop a new chair for café and lunch rooms, which should satisfy the markets expectations and demands and match Kinnarps AB?s assortment today. The project has contained everything from identification of user and customer needs and requirements to evaluation and building of a prototype.The result is a chair with a frame of tubular steel and there is nothing like it in Kinnarps AB?s assortment today.

In the Swedish author, poet and critic Hanna Nordenhöks (1977-) novels Promenaderna iDalbyhage (2011) and Det vita huset i Simpang (2013) the literary characters are often portrayed asdiffuse shapes with a subtile closeness to other organic bodies, places and times. While the novelsaddress themes such as colonialism and subjects becoming, they also explore the act of narratingthrough letters, journals, photographs and, in particular, fabrication. What emerge are two aesthetic,literary works that, on different levels, trouble our notion of borders between human and more-thanhumanbodies, an issue that?s essential for our understanding of human - environmentalrelationship.The purpose of this thesis is to show how the prose of Nordenhök can be read in the light of theterm porosity, where matter is understood as elastic and open for both creating and de-creatinginteractions. I will argue that the novels contribute to a deepened understanding of the relationshipbetween human subjects and more-than-human matter as elastic, and that they incorporate thisdynamic porosity within the narration itself.

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Bakgrund: Fysisk beröring är en central del i omvårdnad och ingår i arbetsuppgifterna dagligen. Under hela livet är fysisk beröring ett grundläggande behov. Patienters reaktioner av fysisk beröring bör omvårdnadspersonalen möta på ett respektfullt och ödmjukt sätt och det är skillnad mellan att bry sig om och ta hand om patienten. Det är för männen näst intill tabubelagt med det kroppsliga vårdarbetet. Syfte: Syftet var att beskriva patienters och omvårdnadspersonals upplevelser av fysisk beröring inom omvårdnad. Metod: Metoden var litteraturstudie med strukturerad litteratursökning med beskrivande design.
