Fossilfria godstransporter : En undersökning av alternativ till diesel som drivmedel för lastbilar

Our modern society is in many ways built with and dependent on fossil fuels, which are used for energy production as well as for transporting humans and goods. Without the oil, many of the things we take for granted would not be possible. During the last century, the use of oil has increased steadily and will probably keep increasing as the world population and the economic well-being for many people increase. Since the oil is a finite resource, we will have to find other fuels that can replace it if we want to keep the same rate of development in the future as the availability of petrol fuels will decrease with rising prices as a result. Furthermore, fossil fuels have the disadvantage that they produce harmful emissions when combusted and thus affect the climate and air quality locally and globally.

Bevarande av svensk låglandsboskap

Sweden signed, in 1992, the Convention on Biological Diversity (CBD) and has thus assumed responsibility for the indigenous biodiversity. That also means that Sweden has a conservation responsibility for the Swedish Friesian (SLB) (SJV, 2007a). In a survey conducted by the Board of Agriculture (SJV) in 1996, it appeared that there were around 780 cows and heifers of the SLB breed (SJV, 1997). SJV did in 2006 a plan for the development of livestock genet-ic resources and the number of cows of SLB was estimated at approximately 200. This meant that the SLB was in need of being conserved and SJV assumed it would be categorized as threatened.The primary objective of conservation of a breed is to reduce the loss of the original genetic variation (Lacy et al., 1995).

Behandlingseffekter av barn med dissociativ problematik

Studier på barn med en dissociativ problematik utifrån ett familje- eller gruppterapeutiskt perspektiv är ovanliga. Enligt Waters (1998) bör familjeterapin fokusera på rak och tydlig kommunikation. Silberg (1997) anser att barngruppsterapin bör ha ett psykopedagogiskt förhållningssätt. Denna studie studerade behandlingseffekterna av familjeterapi, barngruppsterapi och ingen terapi alls för barn med en dissociativ problematik Studien gjordes på en barnpsykiatrisk mottagning och pågick under sex månader, behandling och uppföljning. Urvalet baserades på mottagningens population och egna kriterier.

Vapenhandel : En kontradiktion till EU:s utvecklingspolitik?

Arms trade is a multi-faced issue, it can increase the state's economic revenue; however also endanger the human security. The European Union's member state United Kingdom is one of the five largest arms traders in the world. The EU promotes human security in its work, especially in the union's development policies. These circumstances address the main question of the study: is there a contradiction between the UK's arms trade and the EU development policies. The objective of this study is to research the stately weapon use in three of the UK's trading partners, and how it could affect the EU development policies.

Mobbning i vuxenlivet

Bullying is a widespread problem that currently exists in many places and in different age groups. In our paper we intend to focus on bullying in adult life. As many as 340,000 adult persons are subjected to victimization in the form of bullying, which is about 9 % of the working population. Between 100 and 300 cases of all suicides committed in Sweden can be linked to bullying. Bullying is a social problem that should be taken more seriously than it does.

Mätning av träddelar och flis på Dåvamyran, Umeå energi :

The moisture content in 10 deliveries of tree parts and 10 deliveries of wood residues were measured with different methods to analyze the quality of procedure used at Dåvamyran today. At the same time a survey was made on the measure procedures used at heating plants in Sweden The majority of the heating plants in Sweden use weight and moisture content as base for payment but at some plants only volume. The moisture content is usually estimated by drying wood chips in an oven but few plants a visual estimation is used. At few plants moisture content is estimated spectroscopicily. The techniques using near infra read light and other electromagnetic are still at a test stage. The methods of measurement used today are quit unreliable for the individual deliveries and there is a risk for systematic mistakes.

Kvinnors copingstrategier vid bröstcancer - en litteraturstudie med systematisk ansats

Syftet med denna litteraturstudie var att beskriva vilka copingstrategier kvinnan använder sig av när hon har bröstcancer. Metoden som användes för denna litteraturstudie var Goodmans modell med sju steg för ett systematiskt tillvägagångssätt. Litteratursökningen utfördes i databaserna PsycInfo, Cinahl, PubMed Cochrane, SveMed+ och Medline. Oberoende av varandra har 10 artiklar kvalitetsgranskats enligt Carlsson & Eimans (2003) bedömningsmall som modifierades till den population som undersöktes. Resultatet av tio inkluderade studier visade att det fanns ett flertal olika copingstrategier som kvinnor använder sig av när de har bröstcancer.

Utvecklingspotential till en mer attraktiv bostadsmarknad : En teoretisk värderingsanalys av stadskvaliteter och dess relevans för bostadsbyggandet

Stockholm has in recent years experienced a strong population increase but despite that fact, the demand for housing has not been followed by enough housing contracts. According to forecasts, growth in population will further be continued upward. With more condominiums than rental units on the market, new apartments are too expensive to live in. This creates unsustainable problems for those in lower classes of society. Creating a housing market in the periphery of Stockholm is not sustainable from a social perspective.

Israel, en etnisk demokrati-En studie om Israels demokratiunderskott.

Förekomst av Lawsonia intracellularis och Brachyspira spp. hos häst i Sverige :

Proliferative enteropathy (PE) caused by Lawsonia intracellularis has been reported in horses in the USA, Canada, Australia and Great Britain. Diarrhoea caused by Brachyspira antigen-containing spirochaetes has been diagnosed in a horse in Japan. The presence of Lawsonia intracellularis or Brachyspira spp. have neither been investigated in healthy nor in sick horses in Sweden. The purpose of this study was to survey the occurrence of the two bacteria in Swedish horses. Faecal samples were gathered from 108 foals without any clinical signs of illness in the age of four to eight months.

Bedömning av ögats ackommodativa respons- en jämförelse mellan aberrometri och dynamisk retinoskopi

Syfte: Syftet med denna studie var att undersöka om det finns några skillnader i den ackommodativa responsen när den fastställs med tre olika mätmetoder. De utvalda metoderna för denna studie var dynamisk retinoskopi i form av Nott och Monocular Estimation Method (MEM) samt en COAS-HD VR aberrometer.Metod: 29 personer (7 män och 22 kvinnor) deltog i studien, vars medelålder var 23,6 ± 3,1 år. På varje enskild patient gjordes en subjektiv refraktion med en efterföljande mätning av dess ackommodativa respons med tre olika mätmetoder på ett 40 centimeters arbetsavstånd. Resultaten av studien analyserades med hjälp av Repeated Measures-ANOVA och ett post-hoc test i form av Sidak´s. Överensstämmelsen mellan metoderna redovisades därefter visuellt i form av ett Bland-Altman plot.Resultat: Det visade sig att alla tre metoder gav liknande värden på den ackommodativa responsen, vilket resulterade i att det inte fanns en statistiskt signifikant skillnad mellan metoderna (p = 0,1103) enligt Repeated Measures-ANOVA.

OTEC-Ett energialternativ för enhållbar ö

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.
