Bakteriereduktion i diskmaskiner : Studie av olika metoder för att reducera bakterier
Bacteria are a problem that occurs naturally in dishwashers when the dish stands there dirty for an extended period of time. To get rid of the unpleasant smell that the bacteria is causing, the most common solution is to run a regular washingcycle which can cause problems for the environmentally-conscious consumers since this causes unnecessary energy waste and emissions of chemicals in the washwater. To solve the problem in a more environmentally-friendly way by directly attacking the bacteria with an appropriate bacterialreductionmethod can therefore be an attractive feature in a dishwasher. There are many different ways to treat surfaces that have been exposed to the bacteria. Some high-profile methods are UV-radiation, microwaves and oxidant (ozone) that all three have had success in reducing bacteria in different contexts.
Äckellust : En läsning av Eva Sjödins Gränsland utifrån Julia Kristevas teori om abjektion
Gränsland is a poetry collection by the poet Eva Sjödin. One distinct theme among others in Gränsland is repulsion and attraction, disgust and fascination in interaction. There is also a direction inwards and towards something. This essay is an attempt to analyse this theme. I will apply Julia Kristevas theory on abjection, a theory that explains these contradictory feelings and movements of the subject.
Pallaskattens (Otocolobus manul) beteende i två djurparker - påverkan av hägndesign och miljö
The Pallas cat is a small cat living in central Asia. The cat is approximately the size of a domestic cat but the Pallas cat is more stocky build and has a much thicker fur that enables the cat to live in a climate with temperatures plummeting to -50°C. The thick fur is one of the reasons this cat has been a popular game for hunters in the past. Nowadays there are other threats to the Pallas cat. One of the major threats today is the reduction of food sources.
Kungliga bibliotekets fotografiska förvärv : En undersökning av Kungliga bibliotekets förvärv av fotografier under 1958?2008
My master?s thesis is a study of acquisition of photographies during 1958-2008. The questions I proceed from is what patterns lies behind the Royal library's acquisition of photography and how the process of acquisition looks like. The theoretical base which I lean on consists partly of a problematization of the process of cultural heritage and partly of organizational theory. The problematization of the process of cultural heritage is my foundation of this essay.
Comparison of three IVC systems for mice, with focus on growth and nest building in juvenile mice
Today the individual ventilated cage system (IVC-system) is the most commonly used system when housing rodents. IVC systems are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare for two different strains of laboratory mice (NMRI nude mice and C57BL/6NCrl mice) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. 108 mouse pups from each strain (in total 216 mice) were selected after weaning at an age of three weeks and tested during 5 weeks.
Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats
Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

Symptom patienter upplever efter dagkirurgi till följd av anestesi
Ambulatory surgery is common and develops alongside surgery and anesthetic methods. Time admitted is short and aftercare takes place in the home environment.Objective: The aim of the study was to investigate which symptoms patients experience after ambulatory surgery related to anesthesia. Furthermore how strongly symptoms affect the patient. Symptoms appear as a result of anesthesia and surgery and can therefore be interpreted as nursing induced suffering.Method: Participants were recruited at ambulatory clinics at a Swedish university hospital spring, 2015. Prior to the study permission was granted from the clinic managers. The study is a quantitative descriptive longitudinal study. Data collection forms were administered and data collection was performed by phone.
Fällning av kisel från avloppsvatten vid Hellisheidarvirkjun - experimentell studie
This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

The control group needed to be supplied with a placebo product and the participants could not be on any lipid-lowering medication.
Spårning av miljöstörande ämnen i Uppsala stads spillvattennät
To the sewer systems households, industries and other activities are connected. The wastewater is collected at treatment plants where a nutritious sludge is produced. The sludge does not only contain nutrients, but also hazardous substances originating from different activities in society. To reduce the flow of hazardous substances to treatment plants and to create a sustainable recycling of plant nutrients the Swedish Water & Wastewater Association has developed the certificate system REVAQ. This certificate requires a good quality of the sludge but also that the treatment plants maps the origin of the unwanted substances.
The diffusion of minimum tillage in agricultural China : a study of the factors influencing the farmers? choice of tillage system
The Chinese government´s aim to be self-sufficient in food production in combination with the increased food consumption in China has put high pressure on the productivity within the Chinese agricultural sector (He j et al, 2010). In order to increase the productivity, modernization and adoption of new farming techniques are essential. The opportunity to adopt and import foreign technology has lately been possible in China, as more authority and decision rights have been given to the individual farmers and the country has opened up for foreign trade (Zheng, 2012 & Fan, 1991).
A more open Chinese market enables new opportunities for foreign agricultural companies to expand their businesses by introducing their products to Chinese farmers. But to succeed with this strategy the Chinese farmers must be willing to adopt these, for them new innovations.
Minimum tillage is a tillage practice used worldwide that is suitable in northern China where drought and erosion are the main problems in the crop production (pers.com., Arvidsson, 2012).
Potential users? opinion of new innovations such as minimum tillage is closely related to adoption (Rogers, 2003).
