Geosynteter för hållbara vägar : Modell för jämförelse av vägöverbyggnader med eller utan geotextiler och/eller geonät

The different material layers as part of a road construction fill all a function so theroad becomes durable, safe, comfortable and aesthetically pleasing. Recently, anew group of construction materials started to play an important role in roadconstruction ? geosynthetics.This thesis addresses the two most common types ofgeosynthetics used in modern road construction, namely geogrids and geotextiles.The most common use of geogrids is reinforcement of poor subgrade by usinggeogrid soil reinforcement, which occurs when road material particles wedge inthe geogrid?s mesh. Geotextiles act partly as a barrier that prevents the finermaterial in the below ground from being mixed with coarser upper material andalso act as a load spreader.Road contractors often face a choice of whether geogrids and/or geotextiles areappropriate in a particular road project and also how much profit the choice mightbring. This phase in the tender calculation process is the intended scope of thisthesis.The thesis deals with both the "hard" cost-function aspects and the "softer" values e.g.

Transnationell kooperation : en studie av DLA Agro

Farmers Cooperative has in recent years developed from national markets to cross-border, international, collaborations. One example is the merger between the Swedish dairy company Arla and Danish MD Foods, where the companies collectively are sought to reduce transaction costs and thus improve efficiency. The Swedish market for commodities (fertilizers and pesticides) in agriculture has for many years been dominated by a few large players, with little opportunity for grain associations and local grain companies to offer their customers a varied range of commodities with a competitive pricing.To change this state, a majority of Swedish and Danish grain associations and local grain companies have established a trans-national cooperation. Through the establishment of the organization DLA Agro, they offer their customers a good variety of products with competitive prices. This study investigates thus according to the theory of cooperative models to what extent and how the DLA Agro helps to create benefits for the Swedish member companies.

Förskrivning av antibiotika till hund vid veterinärhögskolan i Nantes, Frankrike :

The purpose of this retrospective study was to investigate the prescription of antibiotics to dogs at the small animal clinic at Ecole Nationale Vétérinaire, Nantes, France. The purpose was also to compare the possible prescription patterns in France with those seen in a similar study by Petersson (2003) at the small animal clinic at the Swedish University of Agricultural Sciences, Uppsala. Antibiotics are very important in veterinary medicine and are used both to treat infections and to prevent them. The use of antibiotics however is not without complications and the risk of developing antimicrobial resistance is of most concern. Resistance has been shown to exist against all currently known antibiotics and potentially all pathogenic bacteria could develop resistance to one or more antibiotics. This study analysed the case records for all dogs presented to the small animal clinic at Ecole Nationale Vétérinaire, Nantes, France during October 2001 and March 2002 to identify patients which were treated with systemic antibiotics. For these cases the antibiotic used, classified according to the ATCvet system, and the indication for use was noted. A total of 292 cases (146 per month) resulted in administration of systemic antibiotics.

Svartrost, Puccinia graminis f. sp. avenae, epidemiologi och bekämpningsstrategier i Mälardalen

Stem rust, Puccinia graminis, has caused enormous yield losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.

Sjuksköterskans möte med anhöriga efter ett trauma med dödlig utgång : En litteraturstudie utifrån både sjuksköterskors ochanhörigas perspektiv. / The nurses? meeting with relatives after a trauma with lethal consequences: A literature review according to

Bakgrund: trauma är en svår kroppslig skada som uppkommit genom yttre våld. Eftersom sorg visar sig olika hos olika individer är det viktigt att kunna se sorgens olika uttryck. Anhörig är den person som patienten anger som sin närmaste. När någon som står en nära plötsligt avlider genom trauma, hamnar de anhöriga i en kris och reagerar och handlar utifrån den. Syfte: är att belysa akut- och intensivvårdssjuksköterskors bemötande av anhöriga vid oväntat dödsfall i ett trauma utifrån sjuksköterskors och anhörigas perspektiv.

Indelning av trakter inför gallring på Holmen Skog : en utvärdering av svårigheter och möjligheter

A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.

Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie

Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.

Kv. Tvättstugan, ett flerbostadshus med massiv trästomme : Ett examensarbete om akustik- och brandkrav samt en jämförelse av energi- och fuktaspekter

Title: Kvarteret Tvättstugan, an apartment building with massive wood construction. A thesis about acoustic and fire requirements and a comparison of energy and moisture aspects. Earlier restrictions in the Swedish legislation have resulted that only a small percentage of the apartment buildings that have been built are designed with a massive wood construction. It has been allowed to build unrestricted with wood since 1994 as long as the function of requirements are fulfilled. This change in the rules together with the great environmental benefits of wood has led to that more companies choose to build apartment buildings with wood. One of these companies is Folkhem Production AB.

Skydda så långt möjligt : den lokala kulturmiljövårdens hantering av kulturvärden i kulturlandskap och kulturmiljöer - en analys av fyra kulturmiljöprogram

The responsibility to identify, protect, look after and develop cultural and historical values in our surroundings - urban as well as rural - falls on the local authorities. This essay focus on local preserve programs for cultural landscapes in Sweden?s municipalities. Programs for preserving cultural landscapes are important tools in the aim to reach a sustainable development of these values. The object of the essay is to delineate how the municipalities handle cultural landscapes in terms of how cultural and historical values is identified, how the landscape is divided and assessed and how different aspects of intangible and tangible values are taken into consideration.

Städer och planetära gränser : En utvärdering av Stockholms ochNorra Djurgårdsstadens påverkan påde planetära processerna

The concept of planetary boundaries was introduced in the year 2009 by a group ofresearchers led by Johan Rockström and Will Steffen. The group presented a draft of thelimits of the planet regarding nine Earth System processes concerning climate change, oceanacidification, stratospheric ozone depletion, atmospheric aerosol loading, interference with Pand N cycles, global freshwater use, land-system change, rate of biodiversity loss andchemical pollution. The starting point for the study presented in this report was that asustainable development only can be achieved if humankind stays within the boundaries. It istherefore, based on the ongoing urbanization, relevant to evaluate how cities affect the EarthSystem processes. The aim of the study was to investigate if Stockholm Royal Seaport (NorraDjurgårdsstaden), a district in the northeast of Stockholm with a clear environmental profile,affects the Earth System processes less than Stockholm in general does.

Utvärdering - till vilken nytta? : En studie om hur utvärderingar användas och vad som gör dem användbara

Syftet med denna studie är att göra en metaanalys kring användningen av utvärderingen Aktiveringspolitikens Janusansikte. Utvärderingen har genomförts i fyra stadsdelar i Malmö inom ramen för storstadssatsningen.Fokus har legat på att undersöka om resultatet av utvärderingen Aktiveringspolitikens Janusansikte har använts i de utvärderade verksamheterna, samt vilka faktorer som påverkar användande eller icke-användande av utvärderingar.För att analysera vilken typ av användning som har förekommit har Carol H Weiss modell för användning av utvärderingsresultat används. Denna har kombinerats tre förklaringsfaktorer för att försöka förstå varför det sker eller varför det inte sker någon användning av utvärderingsresultat. Dessa faktorer är den personliga faktorn, den kontextuella faktorn och utvärderingsfaktorn.Undersökningen visar att användningen av Aktiveringspolitikens Janusansikte inte varit så utbredd i de undersökta stadsdelarna. Däremot framkommer det en generellt positiv inställning till utvärderingar.
