Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in theevent of rainfall. An increased level of radioactivity in the plants may occur due tointerception and retention of the radionuclides. If the content of the plants is above thethreshold limit value, entire yields may have to be destroyed. In order to preventcontamination or decrease the content countermeasures can be taken. The impact of thebiomass, leaf area index (LAI) and growth stage of the plant on the interception andretention is important to know in order to decide which countermeasures to use.Weather may also be an important factor.In this work the interception and retention of 134Cs and 85Sr by spring wheat, ley andspring oil-seed rape was studied.

Metan är en stark växthusgas som är viktig att ta med i beräkningarna när det gäller klimatförändringar. Feedback från myrmarker vid en ökad temperatur i samband med klimatförändringar har diskuterats, bland annat eftersom myrmarker är en källa för metan till atmosfären. Det finns många faktorer som påverkar metanemission, och en av dom är vegetation. Olika sorts vegetation tros bidra olika mycket till avgivningen av metan. Syftet med denna studie var att undersöka hur stor betydelse det har att ta med olika växtsamhällens sammansättning i beräkningarna för att uppnå korrekta uppskattningar av metanemission från myrmark på ekosystemnivå.

Hemp is an ancient cultivated plant that came to Sweden in the 1st to 2nd Century and was particularly interesting for use for food, clothing and building materials. Over time, other applications have been developed for hemp, e.g. in energy and health products. Interesting new uses for hemp continue to be identified and this fascinating plant has incredibly versatile applications.In this project, seed production of industrial hemp in Sweden was studied and evaluated. Five different methods are described, four of which are proven under Swedish conditions.

Underdrainage is a costly investment but often a necessity to maintain rationalized plant cultivation, one can also see underdrainage as insurance to successful plant cultivation. Late ripening crops, low yield and difficult tillage cultivation are examples on an insufficient drainage. (Kvarnemo 1983) A drained field rise in land price and the scheme of the tiled drains is seen as a value item. The interest for underdrainage among the farmers follows with shifting economic situations within agriculture and has for long time been low. A big part of the Swedish tiled drainage systems is since 1930 and ahead. Many of these tiled drainage systems need to be replaced or complemented. The life length of one tiled drainage system varies with maintenance but can still remain in good function after 75 years with correct management.

The common warthog (Phachocoerus africanus) is a relatively long-legged pig with noticeable curved tusks, a short neck and three pairs of facial warts. It has four recognized subspecies. The common warthog is a non-migratory ungulate living on the African savannah. It is a hindgut fermenter and predominantly dependent on high-quality foods. It prefers open areas for grazing but use bushes for cover.

Problem: Utfallet av att vara infekterad i sepsis a?r beroende av tidigt insatt behandling. Pa? grund av det snabba sjukdomsfo?rloppet a?r det avgo?rande fo?r patientens o?verlevnad att adekvat behandling ges tidigt i fo?rloppet, detta kra?ver att sjuksko?terskan har kunskap om de tidiga tecknen som uppvisas vid sepsis. Syfte: Syftet var att underso?ka vilka a?tga?rder sjuksko?terskan ska vidta fo?r att tidigt uppta?cka sepsis hos patienter.

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.

Time of harvest affects nutritional value and digestibility of haylage since plants are in different developmental stages. The aim of this study was to examine the effect of plant maturity of haylage cut in June, July and August on digestibility and faecal particle size in horses.Forage and faecal samples used for the analysis of apparent dry matter digestibility (DMd) and particle size distribution in faeces were from a feed-study performed in the autumn of 2009. Twelve horses were used in the study, divided into three groups in a change-over experiment. Each group was fed haylage harvested in June, July or August during three periods. Faecal grab samples were taken from each horse and pooled so that one sample represented one horse during one period.

Kundomd?men har blivit v?sentligt f?r att best?mma vilket f?retag man vill best?lla varor och tj?nster fr?n (Pollach 2006:2). Positiva kundomd?men kan vara avg?rande f?r ett f?retags ?verlevnad. Men det ?r n?st intill om?jligt att bedriva verksamhet utan att l?mna en enda kund otillfredsst?lld.

Bakgrund: Patienter som st?r p? v?ntelistan f?r en hj?rttransplantation befinner sig i en utmanande och unik situation d?r en transplantation ?r deras enda chans till ?verlevnad. Andra behandlingsalternativ har testats utan att ge bot. Den tid som patienterna tillbringar p? v?ntelistan upplevs ofta som betungande och har en p?taglig p?verkan p? livskvaliteten. Syfte: Att unders?ka patienters upplevelser av att v?nta p? en hj?rttransplantation. Metod: Denna litteratur?versikt inkluderar ?tta kvantitativa och kvalitativa studier som beskriver upplevelserna hos patienter som v?ntar p? en hj?rttransplantation.

It has been shown that moose can affect plant community composition and structure. Selective browsing with other damages of large herbivores on tree species with different tolerance to disturbance could reshape the tree layer in both managed and natural forests. Rowan Sorbus aucuparia is widely distributed throughout Sweden and Europe. Research has shown that browsing by moose may prevent rowan from reaching browsing safe heights. The goal has been formulated that, where rowan is indigenous, it should have a good competition status and be able to reach tree level.

There are two species of potato cyst nematode (PCN), the yellow, Globodera rostochiensis, and the white, Globodera pallida. Each of them can appear in different pathotypes. These are separated by testing the nematode ability to multiply on a number of potato cultivars with different resistance properties. The aim of this project was to examine the virulence of Swedish and foreign PCN populations and to compare two test methods. Biotests are today the only available tests used to study virulence.

Bakgrund: Sepsis ?r ett potentiellt livshotande tillst?nd som kr?ver snabb identifiering och behandling. Sjuksk?terskan har en central roll i det initiala omh?ndertagandet p? akutmottagning, d?r tidig identifiering ?r avg?rande f?r patientens ?verlevnad, lidande och h?lsa. Flera faktorer kan dock f?rsv?ra sjuksk?terskans f?rm?ga att identifiera sepsis.
