Safe retrieval of nutrients to improve food security
Safe retrieval of nutrients from human excreta to fertilize crops in order to gain adequate yields will increase food security and sustainability in agriculture areas with nutrient-poor fields. Safe and nutritious food will meet the dietary needs of the individual which promotes public health and the ability of an active life. Human excreta should be considered as a resource instead of being assumed as waste. Human faeces and urine is excellent fertilizers which may close the nutrient loop if utilized properly. However, sanitation of the excreta is required to prevent disease transmission by reducing the content of gastrointestinal pathogens such as bacteria, viruses and parasites.
The objective of this study was to in small scale evaluate the sanitation in a combined liquid compost and urea treatment by monitor the inactivation of bacteria and viruses at the combination three start temperatures, 45, 40 and 35 °C, and three additions of urea, 0.5, 0.75 and 1 % and reference, 0 % urea addition.
Dokumentation av ensilering med fokus på clostridiesporer i mjölk :
To produce milk of good standard the feed for the animals kept for milk production is an important part in the work of quality. This makes it important to feed them with good forage, especially when feeding with silage. The process of making silage is very complex and requires a careful handling to be successful. The fundamental idea is to create an anaerobic environment in the herbage to favour the desirable micro-organisms, in this case the lactic acid bacteria. This environment is created by careful handlings were the importance is to pack the crop well and cover it as soon as possible to exclude oxygen.
Test av litiumheparinplasma fo?r analys av folat med Siemens Advia Centaur® XP samt effekt av inomhusbelysning o?ver tid
Background: Folate is a water - soluble vitamin necessary for normal DNA synthesis among other mechanisms. Folate deficiency can cause megaloblastic anemia resulting from abnormal erythrocyte d evelopment. At the Department of Clinical Chemistry, Linköping, analysis of folate is performed with Siemens ADVIA Centaur® XP which uses an immunochemical method with chemiluminimetric detection. Currently, the assay is conducted on serum, is poured off and frozen after 48 h and treated with light protection because folate is considered to be light sensitive.Methods: This study tested lithium heparin plasma for analysis of folate with Siemens ADVIA Centaur® XP with the aim to be able to perform a package of analyzes in anemia investigation from the same collection tube. Furthermore, the stability of folate was studied for up to 168 h and examined regarding light sensitivity.Results: Statistically significant higher values were obtained in the analysis of folate in lithium heparin plasma than folate in serum (p < 0,001).
Konstruktion och byggnation av testfixtur för 10Gbit/s transpondermoduler
This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems. The basic elements for the test fixtures are: Test board, switch board and DC/DC board. The main function of the test board is to handle communication between the transmitter and receiver modules and supply voltage to these modules. The test board was insufficient and modified with a microprocessor to handle the communication between the PC and the receiver module.

Ekologi som kommersiell vara
Organic cotton has been in the medias field of vision for quite some time. This interestalso reflects in a growing awareness in the textile industry where more and morecompanies today offer organic cotton in their product range. With this in mind wequestion whether organic cotton has become a viable commercial product. We alsoacknowledge there is a lacking of understanding the complex problems that organiccotton manufacture involves, for example the huge effort and cost required for a transitionfrom conventional to organic cotton farming.The purpose of this paper was to study how textile, ecology and competition today arebeing combined by companies. We wanted with our investigation to find out whethercompanies in the textile industry use ecology as a competitive advantage.
Hej Litteraturen! : En studie av ett läromedel i litteraturhistoria ur ett genusperspektiv
The purpose of this study is to examine, from a gender perspective, Utbildningsradions TV-program Hej Litteraturen! in the light of feminist literature studies conducted during the last twenty years. I want to examine if the feminist literature studies have had any impact on contemporary teaching material regarding the question of how much space in time is given to men versus women and which female authors are included in the literary canon. Hej Litteraturen! is a TV program produced in 2010 intended for high school teaching of literature history. By conducting a content analysis in which I divide the study in a quantitative and a qualitative component, I have investigated how much space and time is given to female writers and how they are presented. My analysis draws on use Yvonne Hirdman?s theory of the gender system. The result shows that the female authors get 37 percent of the total reference space and 42 percent of the time-space. The program has sought to describe male and female authors equally and gives them weight and relevance to the sections in a similar manner. In conclusion, Hej Litteraturen! is a tutorial which embraces parts of the criticisms that have existed in historical literature review papers in general and literary history textbooks in particular. Hej Litteraturen! has worked on gender aspects of the program and by picking up contemporary authors as reference points for literary history in the present, the program contributes not only not only in renewing the literary canon, but also in balancing out the dominance of male writers in the history of literature..
Bevarande av webbplatser : En kartläggning bland statliga myndigheter i Sverige
The purpose of this thesis was to investigate if Swedish agencies preserve their websites according to the Swedish archival legislations and guidelines. As a theory the OAIS Reference Model (Open Archival Information System, developed by US Consultative Committee for Space Data Systems, CCSDS) has been used as a model to show how important it is to develop strategies for public digital information which has to be preserved for long term. The ingest function in the OAIS Reference Model demands that files are prepared for long term preservation and requires that the digital information fulfils established technical requirements.In the study the Swedish National Archive and their advices about preserving websites to archivists on the Swedish agencies are being studied. To control if the agencies meet the requirements for their management and preservation of their websites a survey was sent out to investigate if Swedish agencies preserve their websites. According to the survey result, 84 of 113 agencies preserve their websites in some way. If the technical requirements really was met could not be verified in this thesis, the results was relied on the responses from the authorities.
Riskerar allmänhetens tillit till den svenska sjukvården / till svensk läkarkår att lida allvarliga men vid en legalisering av aktiv dödshjälp i Sverige?
In this essay I have tried to come close to a probable answer to the following question: Is there a risk that the trust between the Swedish public and the Swedish medical services staff, including the doctors, will be severely damaged if euthanasia is legalized in Sweden.In order to try to answer that question, and some other relevant questions that has corresponding interest in the context that euthanasia marks, I have done like this: I have investigated experiences from the Netherlands and from Oregon. Since euthanasia is legalized - though partly in different forms - in both these sites. I have then tried to relate the most relevant parts of these experiences to a theoretical frame. This frame had been set up by three concepts: the sanctity of life, autonomy and trust.I have also tried to come close to understanding the impact that demands for autonomy has in this context. And I have tried to understand if the trust that the public has for a country´s medical services staff and the actual doctors is a form of trust that ought to be understood as a form of trust incorporated in social capital.I have come to the conclusion that there is no great risk that the trust between the Swedish public and the Swedish medical services staff, including the doctors, will be severely damaged if euthanasia is legalized in Sweden.
Dietary intake of zinc and iron within the female population of two farming villages in the Red River Delta, Vietnam
In many developing countries, among them Vietnam, contamination of agricultural land is a major issue that has public health implications. A fast growing population, rapid urbanization and industrialization have led to air and water emissions of potentially toxic elements (PTEs), such as cadmium (Cd). Earlier studies have shown that individuals with low iron (Fe) and zinc (Zn) status absorb larger quantities of Cd than those of adequate nutritional status.
The purpose of this study was to investigate and compare the Fe and Zn intake from the foods consumed by women (15-45 years) in selected households in two agricultural villag-es in the Red River delta in Vietnam. In one of the villages the residents were involved in metal (mainly Fe) recycling activity, whereas in the other village the residents had agricul-tural production as main source of income. Interviews, followed by food intake calcula-tions, were performed.
Jönsaplan blir Östra torget : ett torg för sin tid
This project is about Jönsaplan in Landskrona. Jönsaplan is situated at the center of Landskrona in a part called Södra centrum which the municipality is developing, mainly by building new residential buildings. Today, Jönsaplan is not a functioning square. This is due to a ferry terminal and its many fences that block the way for people. In this project, I have assumed that the ferry terminal will be moved somewhere else so that Jönsaplan can be a real square.
By studying The Concise Townscape by Gordon Cullen and Byens uttrykksformer by Thomas Thiis - Evensen and three reference places, Daniaparken, Raoul Wallenbergs torg and Norr Mälarstrand, I came up with a number of guidelines for my design proposal for Jönsaplan.
