Miljömärkningar och medvetenhet : En studie om unga vuxnas medvetenhet kring miljömärkningar
Dagens samhälle är präglat av materialism och dagens konsumtionsmönster är ohållbara ur miljömässig synpunkt. Konsumtionen skapar därmed miljöproblem och ett viktigt styrmedel för att göra den mer hållbar är miljömärkning. Miljömärkta produkter produceras på ett miljöansvarigt sätt utan kemiska bekämpningsmedel och gödsel som är skadliga för både människa och miljö. Syftet med denna studie var att undersöka den nuvarande medvetenheten kring miljömärkningar hos unga vuxna på Möckelngymnasiet. Metoden för studien var enkätutdelning till skolklasser som går sista året på gymnasiet.
Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Samband mellan anknytning och självkänsla hos ungdomar. En pilotstudie
Background:When the patient is critically ill the family is in a vulnerable position. The nurse's role is to support and help the family to find meaning in the difficult situation and to provide realistic hope. Balancing between the patient's and the family's needs is difficult. Knowledge about how nurses experience difficulties in the interaction with family is required in order to grant good care too critically ill patients and their family-members.Aim:To describe nurses' perceived difficulties in the interaction with family-members of critically ill patients.Method:The study is a qualitative literature-based study based on qualitative research. Results: The analysis resulted in four main themes; difficult disunion, environmental constraints, interpersonal difficulties and communicative difficulties.
Transfetter från idisslare - och dess inverkan på blodlipidprofilen hos friska män och kvinnor
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Trans fatty acids from ruminants - and its effect on blood lipidprofile in healthy men and womenAuthor: Sophie Berg and Sara KarlssonSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundCardiovascular disease is the most common cause of death in Sweden. It is well known that thereis a link between high consumption of industrial trans fatty acids and cardiovascular disease, buthow natural trans fatty acids affect us remains uncertain.ObjectiveThe purpose of this article is to, based on the currently available scientific evidence, concludewhether an intake of trans fatty acids from ruminants generates an effect on the bloodlipid profile of healthy men and women.Search strategyRCT articles were obtained through searches in databases such as PubMed, The CochraneLibrary, and Scopus. Keywords used were "ruminants" AND "Cholesterol" AND "Trans FattyAcids" and "ruminants" AND "Blood Lipids" AND "Trans Fatty Acids".Selection criteriaInclusion criteria were RCT studies conducted on healthy people who did not receive medicationfor hyperlipidemia. Moreover, the results were to be based on fasting blood samples, where atleast ten hours of fasting preceded the analysis of the blood lipids.Data collection and analysisThe search generated eight studies. These were graded according to SBU:s Granskningsmall förrandomiserad kontrollerad prövning, after which four studies were selected.
Personlig integritet på Internet : En studie om attityder
The internet has fundamentally changed the way people communicate. With all the information that we are sharing over the internet, and the ways which companies want to use our information, the importance of keeping our private information secure has increased. This thesis aims to discover what attitudes internet users have against privacy on the internet, and what ? if anything ? they are doing to protect their personal privacy.We distributed an online survey to internet users in the Stockholm area, and conducted three interviews with persons in our target population. The results of these studies show that people in general are very aware of privacy concerns on the internet, but that their attitudes toward how important personal privacy on the internet is, differ somewhat..
Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning
The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Med minskad komplexitet får ett system ökad användbarhet Fallstudie av användbarhet i ett affärssystem
One of our reasons is that we think the subject usability is interesting, is
that we think it is an important. Usability is maybe the most important element
when you develop or choose a system because it can save money for the companies
and give the users a more delightful and better work environment. The aim of
the investigation is to find out if the implementation of a web portal is a
direction to reach higher usability in a complex system that consists of
several different interacting applications.
The objective of our investigation is to show if the implementation of a web
portal is a direction to reach higher usability in a complex system that
consists of several different interacting applications. In our case we will try
to see if Karlshamns AB:s recently implemented web portal is more useful than
their previous application (Movex with interacting programs)
One thought with the report is to give the system developers a perspective of
how the usability can be in-house made applications versus standard
applications. Also companies that not have any computer- or department for
development and which are thinking of get hold of, change, replace or
complement their system and applications, may have some interest in our thesis.
We have used a qualitative investigation method in our study to answer our
hypothesis.
The first Woman born with a Difference : En komparativ queerläsning av Djuna Barnes Ladies Almanack
The aim of this thesis is a comparative study of Djuna Barnes' 1928 book Ladies Almanack and turn of the century sexological texts focusing on Havelock Ellis' studies of 'sexual inversion in women'. The study is based on queer theory concepts from Judith Butler and Fanny Ambjörnson as well as Michel Foucault's studies of the history of sexuality. After a presentation of the theoretical concepts and a short introduction of earlier research on Barnes' works my reading and conclusions are presented in five chapters focusing on different theoretical and thematic aspects of the studied texts. A recapitulation and discussion ends the thesis.In short, my conclusions are that Ladies Almanack contrary to earlier research can be read as a queer text, and a form of counter-discourse to the general one regarding lesbianism in the early 1900's. The text also reveals itself as a pointed critique and a satire of Havelock Ellis' writings on 'sexual inversion in women'.
Att effektivisera ett förvaltarbolag
Executive SummaryThis final thesis has examined the effects of an increased centralization and better coordination of the distribution logistics at ABB in Västerås. The company is today strongly decentralized and there is a minimum of collaboration between the 20 business units. This is why the questions were raised; how could the business units coordinate outbound logistic activities and what effects would that provide. The objective of this final thesis is to provide basic data for a future decision-making which describe these effects.The report has mapped out the factors that are important to ABB in an evaluation of their logistic activities and how the outbound logistics work today. The four factors are cost efficiency, delivery service, environmental impact and logistics capability.
Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften
The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.
Mätning av abrasivflöde för vattenskärningsmaskiner
The content of the following report is the summarized result of three students
thesis at Blekinge Institute of Technology in co-operation with Water Jet
Sweden AB.
This report will give the reader a description of principles how to measure the
abrasive mass flow in a waterjet cutting system.
The work began with a visit to Water Jet Sweden AB to get a closer look at the
problem. When the analysis of the problem was done the criteria were defined in
the form of demands and desires. The main task of the criteria was to guide the
search for the solution. The work proceeded with an extensive search for
abrasive flow meters along with obtaining information about flow measurement in
general. When the search for abrasive flow meters resulted in nothing all the
efforts were concentrated on finding a principle of measurement that could cope
with the criteria.
Hållbar utveckling: Hjärtefråga eller nödvändigt ont? ? Miljöarbete hossvenska SME-företag i konfektionsbranschen.
The aim of this thesis is to give an insight to how work is being pursued within Swedish SMEin the clothing industry. Furthermore we investigate how efforts can proceed withenvironmental questions in a quest for sustainable development and bring clarity in thedifficulties that occur. Through the use of company examples and a description of how theywork we wanted to give stakeholders knowledge in what resources and procedures that areused today on the market. The function of the report is moreover to provide Swedish smalland medium-sized clothing enterprises suggestions and directions of how to advance withinsustainable development.In our theoretical frame we have chosen to administer the theories that we found suitable forour study. Seen from a perspective of sustainability we have thus applied the theories ofstakeholder and legitimacy, an analysis model for a company?s actions in environmentalquestions and the theory of SME which describes a small or middle sized enterprise?s fivecompetitive variables.The empirical frame we acquired for this thesis is presented in three chapters.
Tredjemanskontroll - Säker rätt är säkert rättssäker : En studie med utgångspunkt i betänkandet Förbudet mot dubbla förfaranden och andra rättssäkerhetsfrågor i skatteförfarandet (SOU 2013:62)
SKV and Tullverket have several important tools and methods available in each activity to ensure that taxes and fees are paid and charged rightfully. Among other things they use tax or customs surcharges, targeted and general third party injunctions or targeted and general third party audits. The targeted controls, ergo targeted injunctions and audits, are targeted towards specific persons or documents while during the general controls these are not specified. The methods have repeatedly been the subject of discussions and attempts to simplify the tax procedure and increase the Rule of Law for the individual.The government appointed a commission on March 8 of the year 2012 with the assignment to prepare proposals to increase the Rule of Law in the tax procedure. The assignment was therefore to analyze the areas of tax and customs injunctions, reimbursement because of expenses and agents and also third party controls.
Debattens tvärmediala rörelser - en studie av tre debattformat och deras förutsättningar
This thesis studies three kinds of debate formats. Those are DN Debatt, SVT Debatt and Ring P1. The focus lies in the interrelations between these forums and how they interact with theri audience. Since debate is an essential tool for political and democratic practice, it is vital to study the movements and the realtions between these media formats. Some of the questions in this study are: What happens with a debate topic when it moves between the formats? In which way are the formats democratic and what does their communicative forms mean for political practice and citizen participation? The study shoes how the interpretation of a specific term can expand during a debate.
