Etiologi för sporadisk hepatit E i industriländer
Det finns många olika typer av bromerade flamskyddsmedel. De är alla stabila i miljön men graden av toxicitet och bioackumulering varierar. Att bromerade flamskyddsmedel är
endokrinstörande är känt men min hypotes är att de även är neurotoxiska och att de kan orsaka neurologiska störningar hos människa.
Människor exponeras för bromerade flamskyddsmedel via damm och föda. Barn och foster som är känsligare än vuxna kan även exponeras via modersmjölk respektive placenta. Barn
har högre serumkoncentrationer av bromerade flamskyddsmedel än vuxna.
Återhämtningsprocessen hos en svensk livsmedelsproducent efter ett allvarligt produktfel : En studie av Findus hantering av ?Hästköttsskandalen? under våren 2013
This study deals with a Swedish company in a food industry that got affected by product failure, which led to consumer trust crisis followed by media and was needed to be managed. Situation had a negative impact on company?s trademark, which acquired long recovery work by the company. Study is following a case example of Findus problems with having horse meat in their meat product that was supposed to contain beef meat. Study aims to research how the company dealt with situation, through crisis communication and recovery strategies.
Mineral composition of New Zealand monofloral honeys
The objective of this study was to determine the mineral content in ten New Zealand monofloral honeys, in order to distinguish whether New Zealand monofloral honeys are a good source of minerals compared to honeys from other parts of the world. The ten monofloral honeys were collected from a local honey factory (Airborne Honey Ltd, Leeston), Clover, Honeydew, Kamahi, Manuka, Nodding Thistle, Rata, Rewarewa, Tawari, Thyme and Vipers Bugloss honeys were been investigated. The water content, water activity, pH, conductivity, colour and mineral content were evaluated. The water activity was averaged for all the ten New Zealand monofloral honeys and set to 0.59 aw, which indicates a high stability and long shelf life as a food stuff. A strong correlation between total mineral content, pH, conductivity and colour was obtained.
Personlig hygien på stycknings- och charkanläggningar : hur personalen på tre anläggningar följer och ser på rutiner för personlig hygien
Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition.
This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking.
The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.
Det litterära spädbarnet ? en undersökning av folkbibliotekens program för de allra yngsta barnen
The objective for this Master?s thesis is to study literary programs for infants at six Swedish public libraries, their relevance and importance for infants and how the infant?s perspective in the program design and implementation is taken into consideration. The questions I pose are: In which way do the programs take the infants need for development and their literary prerequisites into consideration? Which functions can the programs have for infants? I have used a qualitative method, based on deep interviews with six library staff, working with literary programs. A model was developed based upon Daniel Stern?s theories of the interpersonal world of the infant together with Joseph Appleyard?s reading development theory.
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..
Zoonotic Pathogens at the Interface between Humans and Animals in Cambodia, a Rural Approach
A zoonosis is a disease or infection that is naturally transmitted between vertebrate animals and humans. The majority of infectious diseases that affect humans are zoonoses. Environments where wild animals, domestic animals and humans live in close proximity with no or small boundaries in the ecological system favor the transmission of diseases between animals and humans. The above described situation is more common in low income countries, where humans and animals live in high density and zoonoses are generally more common. The study was conducted in Cambodia.
Barns inflytande, delaktighet och intresse : En studie om samspel och förhållningssätt i förskolans vardag
The aim with this study was to give and receive an insight of children?s participation during one day in a preschool. Answers we were interested in finding out were how pedagogues act in relation to children´s influence, participation and interests and how this shows in the pedagogical context. Our own interest of children´s participation was influenced by the new revised curriculum that took place in 2010. Nowadays the pedagogues? have to be more active and reflect and document children´s influence and participation, and therefore we wanted to use this opportunity to create a picture of how pedagogues deal with these new guidelines.We have with an ethnographic inspired approach performed a qualitative study with data collected during one day with focus on children´s influence, participation and interest in one preschool section.According to the result children?s participation and influence this day were controlled by the pedagogue.
Genomförande av e-handelsdirektivet i svensk rätt
Along with the development of technology, the cross-border trade is increasing and therefore there is a need for greater consumer protection. A good consumer protection creates a feeling of safety for the consumer and that by itself may help to increase cross-border trade. This is one of the reasons for why the EU has established regulatory framework for electronic commerce, for example the Directive2000/31/EC. The direc-tive strives to create a similar law for electronic commerce within the European Union. This paper?s main purpose is to ensure that the directive is implemented properly in Swedish law, and if there are other possible ways to achieve the objective, other than the ones that the Swedish legislator has chosen.

Ståndort och växtval på takterrasser
In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.
Hur kan måltiders klimatpåverkan minska? : Hinder och mo?jligheter fo?r va?xtbaserad kost vid offentliga matserveringar.
Människans utsläpp av miljö och klimatpåverkande växthusgaser har ökat i snabb takt de senaste hundra åren. Fler varor produceras, konsumeras och transporteras över hela jorden för att uppfylla de krav människor har på sin levnadsstandard. Livsmedelsindustrins roll i utsläppen är betydande, speciellt köttproduktionen, som står för 18 procent av världens totala växthusgasutsläpp. Genom att minska den mängd kött som ingår i människors måltider och gå mot att äta mer växtbaserat, som inte innehåller köttprodukter, kan matens miljöpåverkan minska. Ett viktigt område är offentliga matserveringar, vad som serveras där har en inverkan på människors matvanor och deras syn på mat.
Bones are Beautiful : En etnografisk studie av ungdomars användning och behov av Pro-anakulturen på Internet
There are several possibilities for those with an eating disorder, who wishes to get treatment and recover to get help and support. But for those who are not ready to recover, there are not any help to receive. Pro-ana is a youth culture where individuals who want to achieve the anorectic ideal help and support each other. The purpose of this study was to describe and analyse the content and the need for the Pro-ana community on Internet, among young people with eating disorders. More specifically the aim was to find out how young Swedish people uses the Pro-ana communities on Internet.
