In search of Umbilicaria subglabra In Sweden Umbilicaria subglabra has its only known occurrence in Lybergsgnupens nature reserve in the county of Dalarna where it has been found only once in 1936. It was found on the east-facing rock spur, approximately 650 meters above sea-level. The lichen is now red-listed as Regionally Extinct (RE) in Sweden. The aim of this study was find U. subglabra.

Sweden has been a member of the European Union since 1995 and the power of the organisation to make decisions has increased over the years in a rate which hasn?t been followed by an equally increase in democratization. This is partly due to the lack of participation in the decision making process and at the national level the citizens don?t possess enough channels to compensate the loss of influence. To solve this democratic dilemma, more and more countries are turning to the referendum.

Bakgrund: En kombination av olika riskfaktorer och ett yttre tryck bidrar till att patienter drabbas av trycksår. Sjuksköterskor i samarbete med undersköterskor ansvarar för att förhindra risken för trycksår hos patienter. Tidigare studie påvisar att femton procent av inneliggande patienter på sjukhus drabbas av trycksår. Syfte: Syftet med studien är att belysa varför patienter får trycksår trots att sjuksköterskan i samarbete med undersköterskan bör ha kunskaper för att förebygga vårdrelaterade trycksår. Metod: Författarna använder sig av metoden allmän litteraturöversikt.

Syftet med denna litteraturstudie var att undersöka om nutritionstillskott, tryckavlastning och typ av förband har någon påvisad effekt på läkningen av trycksår. Litteraturstudien grundar sig på Goodmans systematiska tillvägagångssätt. Litteratursökningen gjordes i CINAHL, PubMed och The Cochrane Library samt att artiklar som inte var tillgängliga i fulltext via någon av databaserna söktes via Samsök. Granskning och kvalitetsbedömning av artiklarna gjordes individuellt utav författarna oberoende av varandra utefter ett modifierat granskningsprotokoll. Elva artiklar av varierande kvalitet inkluderades i litteraturstudien.

Vattenfall Heat Uppsala runs the waste incineration plant in Uppsala, which produces district heating, process steam, district cooling and electricity. Vattenfall Heat Uppsala has decided to introduce an energy management system with the aim to increase the energy efficiency of the plant. The basis in such a system is to make an energy mapping.In this thesis an energy mapping has been performed at the waste incineration plant with the aim to identify and determine the size of energy flows. The investigated energy flows are used fuel, produced and used steam, produced district heating and cooling. Also the use of electricity to run the processes has been investigated.

Syftet med denna litteraturstudie var att beskriva hur sjuksköterskor arbetar med preventiva åtgärder vid trycksårs uppkomst samt vilka omvårdnadsåtgärder som ges till patienter som utvecklat trycksår. Vetenskapliga artiklar söktes i databaserna Medline via Pubmed och Cinahl med sökorden nursing, pressure ulcer, prevention, treatment, therapy, intervention. Endast artiklar från år 2003- mars 2008 användes i studien. Både kvantitativa och kvalitativa artiklar användes, dessa artiklar granskades utifrån två modifierade granskningsprotokoll. Resultatet påvisade variationer av dessa preventiva insatser som sjuksköterskor använde sig av.

In the assembly process of airframe structures there are many drilled holes and on some parts the holes are mainly drilled manually with pneumatic handheld drilling machines. During conventional drilling in metal, burrs appear. To remove these burrs the parts of the structure must be separated and deburred before they can be put together for fastening. This is a time consuming measure and therefore expensive. To facilitate this process and lower production costs some parts of the process needs to be automated.A part of this thesis was a project in co-operation with Saab, Novator, Specma Automation and the University of Linköping.

WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. The question was raised whether thenegative correlation between extractable ammonium and biochar specific area reflects the amount ofammonium present in the soil or its extractability from the biochar, and whether methods forextracting soil mineral nitrogen, like KCl-extractions, have to be modified for application on biocharamended soils. There was a tendency of increased nitrate retention and KCl-extractable nitrate withbiochar and KCl-extractable nitrate was positively correlated with the specific area of the biochar. pHwas higher for all biochars compared with control, although the differences were not significant, andWFPS was lowered by biochar addition, significantly in one case.

The popularity of vegetated, or green roofs, has grown over the past years due to their potential function of maintaining urban environment quality. The aim of this study was to investigate if substrates with different organic material, peat and charcoal, with two contents (3 or 6 weight%) influenced the growth of the cuttings during the first critical period of the establishment. Biochar is used as amendment to agricultural soils and has, theoretically, many of the properties suitable as organic content in green roof-substrates. Peat is one of the materials that is commercially used in green roof industry. The substrate has been treated with different amounts of water.

Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.

Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

 The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.

The aim of this review was to examine scientific literature to determine what kind of physiological and psychological benefits derive from human-dog interaction, as well as attempt to uncover a possible mechanism behind these benefits and whether or not they are mutually beneficial. A growing body of research indicates there are physiological and psychological benefits associated with human-dog interaction. Significant cardiovascular benefits have been linked with human-dog interaction, as have lowered blood pressure, cortisol and heart rate. Interaction with dogs is often associated with a feeling of social support and well-being, and dogs also seem to facilitate social interaction between people. Dogs? ability to buffer and reduce stress is also well documented. A strong indication was found regarding a relationship between physical contact and benefits associated with human-dog interaction.
