Vill EU vända på steken? : En kritisk analys av EU-kommissionens ställningstagande i frågan om animalieproduktionens klimatpåverkan

This thesis examines the ongoing European political debate on the links between livestock production and climate change. In the end of 2006 the UN Food and Agriculture Organization (FAO) released their report Livestock?s long shadow, showing that livestock production represents some 18 % of the total global greenhouse gas emissions. The purpose of this paper is to explore the European Commission?s position and response to this question since the release of the report.Using Arne Naess? argumentation analysis, statements made by the Commission will be systematically organized and broken apart.

Reduktion av föroreningar i processvatten från en äggfabrik i Brasilien : Kväve- och fosforrening i anlagda våtmarker.

A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes. The wastewater from the factory consistedof process water from manufacturing and water used for cleaning, no stormwater or sewagewater entered the system. Tests were taken three times a month from October 2013 ?til April2014.

Påverkan på elektronik och sensorer i radiologisk miljö

The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..

Diakoni och Välfärd - en kvantitativ studie av ekonomiskt stöd inom Svenska kyrkan

The aim of this thesis was to study financial support within the Church of Sweden and the view of the church?s diaconal work. This was done with a quantitative method where a survey sent to a number of churches containing questions about financial support within the church and how they, the respondents, looked at the church?s role as a welfare agent. Of the almost 200 congregations only 23 congregations responded.

E-handel : En studie kring betallösningar, säkerhetslösningar och certifieringar för små e-handelsföretag

Syftet har varit att på uppdrag av Periallo identifiera vad kunder tycker är viktigast ur ett säkerhetsperspektiv. Detta har skett genom att besvara frågorna vad som är viktigt för konsumenterna ur ett säkerhetsperspek-tiv när de handlar av små e-handelsföretag och vilka säkerhetslösningar samt betallösningar som är relevanta för små e-handelsföretag. Vi har även undersökt om det är värt för ett litet e-handelsföretag att investera i en certifiering. Arbetet har kartlagt betallösningar, säkerhetslösningar och certifieringar med hjälp av en kritisk litteraturstudie och med en enkät, det vill säga en kvantitativ metod. Resultatet av undersökningen har visat att de flesta kunderna känner sig trygga när de handlar på Internet.

Ödet i omvärldens händer : - En kvalitativ studie av humanitära hjälparbetares motiv och riskuppfattning

The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.

Flavan-3-oler och endotel -dysfunktion

Background: Flavan-3-ols are polyphenolic phytochemicals belonging to the flavonoids. Flavan-3-ols are present in many higher plants and are particularly concentrated in e.g. Camellia sinensis (tea) and Theobroma cacao (cacao) and have got attention due to their antioxidative capacity. Many studies have been able to associate flavan-3-ol-rich foods to improved endothelial function. The aim of the present work is to review the scientific literature and evaluate the evidence for positive effects of flavan-3-ols on endothelial dysfunction in humans. Method: Scientific articles describing intervention and observational studies about flavan-3-ols and endothelial dysfunction, were searched for on http://www.pubmed.org.

Praktiska råd gällandeBusiness Intelligence-projekt : En studie av hur fyra organisationerhanterade problem och vilka erfarenheter dekan dela med sig.

This study concerns how organizations manage various problematic areaswhen implementeing Business Intelligence and experiences from BusinessIntelligence project failures on management level. In order to highlightthese questions, we have carried out interviews with four organizationswhich have great experience in working with Business Intelligence on adaily basis.The result of the study shows that all organizations deal with difficultiesregarding cost-benefit issues and justification concerning BusinessIntelligence investments. The result also showed that the organizationsfaced difficulties with integration concerning time and cost. Documentingand securing support systems presented different attitudes between theorganizations, primary in the question about sub complements to BusinessIntelligence and in the way that they were documented. In the discourse oflegal issues and privacy the majority of the organizations chose not to storepersonal information relative to legal security demands.

Statsförfall ? Transnationellt terroristskydd eller temporärt gömställe?

Many theories describe failed states as potential threats to international security due to the breeding ground they constitute for transnational terrorism. Ken Menkhaus believes however that transnational terrorists are dependent on a state for their own protection in order to be able to operate.This essay seeks out the relevance in Ken Menkhaus? theory which states that transnational terrorists rather exploit corrupted states than operate in countries where there is a state collapse. His theory will be applied on a case study on post-Libya after Gadhafi?s fall.

Private-Public Partnerships (PPP) : collaborating for a sustainable business in Sweden

In theory, the logic behind partnerships is simple: All organisations have strengths, but no organisation has all the strength required to do everything. Triggered by global perspectives and challenged by sustainability objectives, the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992 pointed out needs for corporate responsibility. In this conference, Private-public partnership, PPP, was identified as a potential way to work towards sustainability, especially as a way to emphasize a corporate responsibility commitment. Nowadays, organizations exist to satisfy the needs and interests of all their stakeholders, such as customers, markets, shareholders, as well as secondary stakeholders such as media, NGOs, and society at large. Addressing all stakeholders and working towards a sustainable business development makes PPP a potential solution, but also a source of challenges.

"Jag brukade skoja och säga att de hade vuxit en skostorlek varje gång jag träffade barnen : " (Sagt av en pappa då han beskrev hur sällan han såg sina barn)- En studie kring frihetsberövade pappor och deras barn.- An essay about incarcerated fathers and

ABSTRACTTo be a incarcerated parent and separated from your children can awake difficult thoughts and feelings of being powerless and burdened with debt. When it gives possibilities to maintain connections between the parent and child it can make a feeling of belonging and security. Children and families have long struggled with the difficulties created when a parent goes to prison. The aim with this essay has been to look into how fathers in prison, professionals from correctional institutions and social workers experiences of the connections between children and their incarcerated fathers. We reached our aim through interviews with fathers who had been incarcerated, professionals from correctional institutions, social workers and by literature studies.

Barnen som inte fanns : En kvalitativ studie baserad på självbiografier med fokus på individers upplevelse av omsorgssvikt

The aim of this study was to describe and understand how individuals in adulthood experienced a childhood with neglect, and how they handled neglect. In order to reach the perspective of the individuals who grew up with neglect, we chose to use autobiographical books as our empirical material. The criteria the autobiographies had to meet in order to fall within the scope of this study was that the biographies had to display the experience of neglect during childhood, and thereto the books had to be written by individuals who themselves experienced neglect. Based on the aim of this study we sought answers to three questions: How do the individuals describe their upbringing with a mentally or socially disabled parent? How have the individuals coped with the neglect they?ve been exposed to? What consequences have the neglect supposedly led to? The findings of this study show that the extent to which the individuals experienced neglect were profound and comprising.

Konsumenters attityder kring livsmedel och livsmedelssäkerhet

Konsumenters attityder till livsmedel och olika aspekter av livsmedelssäkerhet undersöktes i en intervjustudie i Upplands län, i vilken olika frågor kring attityder till livsmedel med fokus på livsmedelssäkerhet ingick. Resultatet visade att det absolut viktigaste för konsumenter när de väljer varor är att livsmedlet smakar gott, då samtliga respondenter uppgav att detta var viktigt. Att konsumenter oroar sig mer för toxiska restsubstanser såsom läkemedelsrester och bekämpningsmedelsrester än för livsmedelsburen smitta framkom, liksom att få uppfattar sitt eget hem som en plats där man kan bli matförgiftad, trots att tidigare studier visat att en stor andel av matförgiftningsfall smittas i sitt hem. Oroande stora andelar av konsumenterna kunde tänka sig att äta olika livsmedel med förhöjd risk att drabbas av matförgiftning såsom otillräckligt upphettad kyckling, och ett flertal enkla men viktiga hygienåtgärder för att undvika korskontaminering uppfattas inte av konsumenterna som viktiga att utföra, vilket kan leda till onödigt många matförgiftningsfall. Djurvälfärd och livsmedelssäkerhet är beroende av varandra och aktuellt arbete visar att svenska konsumenter anser att djurvälfärd är viktigt..

Animaliska restprodukter vid köttproduktion : Effektiv användning och livsmedelspotential

This master thesis aims to investigate and quantify the potential associated with increasing the usage of edible by-products as food for human consumption on the Swedish market. The main emphasis is on the Swedish production of offal and the obstacles that currently inhibit greater usage of these products as foods.The results indicate that the Swedish market for offal is limited. Only a small amount of the edible by-products that are produced in Sweden every year are consumed as foods and a considerable amount seem to be downgraded into animal feed or thrown away. The utilization of these products is restricted by economical, technical, legal, and cultural factors that all need to be taken into consideration. On the whole, large-scale slaughter plants seem to be more inclined to utilize these products effectively, as the profit from doing so increases proportionately to the produced volumes.
