Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.

Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.

Background: Delirium is a common condition among elderly patients who are being treated in a hospital environment. However, a large number of patients are wrongly diagnosed. The highest risk categories to develop delirium are elderly people and postoperative patients. By understanding the patients´ experiences the nurse can formulate the care to make it easier for the patient. Aim: The aim of the literature review was to illuminate elderly patients´ experiences of delirium in connection with a hospital visit.

Magnetic resonance imaging (MRI) is a safe and painless diagnostic method. The patient may become concerned, suffer from anxiety and experience the examination as unpleasant. Detailed information and a good treatment can reduce anxiety and distress for the patient. The purpose of this study was to illuminate the patient?s experiences in connection to MRI, and to describe the patients needs for information and treatment.

AbstractThe purpose of this paper is to examine how the religious education is implemented in junior and grammar school. As a base for my examination I used two private schools and two municipal schools. My main goal was to get a better view of the content of the education, the treatment of the students and the conditions for the students to get a greater understanding and respect for others? religious beliefs and opinions through education. To reach this goal I did interviews and field studies which means that the paper has a qualitative approach.The examination showed clearly that the private schools spend a lot more education time on their respective religions while the municipal schools have a more comprehensive education.

These days, schools are obliged by the law to prepare an annual plan for the prevention of bullying and degrading treatment. The purpose of my work is to investigate the 2 schools efforts to prevent bullying and abuse and how they live up to legal standards. But I have also examined how students in school are experiencing anti-bullying work in their school. I have also examined how much funding schools put on to prevent bullying I school. In this study, I have done interviews with school principals and students to have a clear picture about the school?s anti-bullying work.

The WT1 gene is a complex gene originally known to suppress cancer in kidneys. Studies of WT1 knockout mice have confirmed the important role of WT1 in the pathogenesis of Wilms? tumour, a tumour which counts for 95% of all childhood renal tumours. In that case the WT1 gene acts as a tumour suppressor gene. Subsequent research has shown that the WT1 gene in many other cases acts as an oncogene, e g in leukemia or lung cancer (even though these cancer forms can emerge as a result of many other aetiological factors).

Today evidence exist that environmental chemicals deteriorate male sperm quality and that testicular cancer is increasing. Bisphenol A (BPA) is a chemical with estrogenic effects used in the manufacture of polycarbonate plastic and are found in, for instance, plastic boxes, feeding bottles and food containers. Much of the research on how men's reproductive ability is influenced are performed on rats. This review article complies how male rat reproduction is affected by BPA as a model for humans. Studies have investigated how sperm are affected, hormonal changes during reproduction and how reactive oxygen species (ROS) affects sperm.

The purpose of this study is to make a qualitative evaluation of the MTFC-program (Multidimensional Treatment Foster Care) on the basis of six youth´s experiences of the program. The study will investigate what the youth experienced as positive and negative about the program as well as finding out what has helped them or inhibited them from the aim of getting out of their criminal lifestyle. A secondary purpose of this study is to make the youth´s voices heard in the research world. The research question is: Which factors in the MTFC-program have helped or inhibited the youth towards the aim of getting out of their criminal lifestyle? For this purpose, a qualitative research method has been used where semistructured interviews have been performed on six youth who have gone through the MTFC-program.

The Swedish mental hospitals existed for about one hundred years, the period around 1880-1980. The research is intended to be from a local setting perspective to study the local approach used to meet requirements from Furunäsets mental hospital principals 1960 - 1972, the effect this had on the care and treatment of mentally ill patients and how Swedish society's changing approach to mental health influenced the process. The results of the research showed that Furunäset searched for ways to meet the principals' requirements which often went against the patients? personal best. Furunäsets mental hospital strove to fulfill its institutional goals in them selves rather than giving patients the care and treatment they needed.

Denna studie syftar till att beskriva patienters upplevelse av läkemedelsassisterad behandling för opiatberoende (LARO), även kallad underhållsbehandling. I studien undersöks hur upplevelsen av LARO är och hur den beskrivs utifrån två olika patientgrupper; de patienter med en mindre välfungerande behandling som dagligen går till mottagningen för att ta medicin övervakat och som lämnar urinprov två gånger i veckan, samt de patienter med en välfungerande behandling som går till mottagningen två gånger i veckan för att lämna urinprov men hämtar medicin på apoteket. I uppsatsen har sex patienter intervjuats om hur de upplever LARO. Uppsatsens resultat illustrerar bland annat upplevd brist på delaktighet och empowerment i behandlingen samt vikten av en god relation mellan patienter och personal på LARO-mottagningen. Studiens slutsats är att Patient empowerment bör vara grundstenen i all arbete med omvårdnad och behandling..

Hormonersättningsterapi (HRT) används för att lindra vasomotoriska och urogenitala symtom associerade med klimakteriet. Eftersom behandling med enbart östrogen förknippats med endometriell hyperplasi och livmodercancer, tillsätts progestagener till östrogen-beredningar i HRT hos kvinnor med intakt livmoder för att motverka den proliferativa effekten av östrogen och förebygga cancerutveckling i livmodern. Sådan kombinerad HRT har emellertid associerats med ökad risk för bröstcancer. Vid kombinerad HRT används olika typer av progestagener och olika behandlingsregimer (kontinuerlig eller sekventiell tillförsel).Syftet med detta arbete var att undersöka vad som ökar risken för bröstcancer vid kombinerad HRT: valet av progestagen-typ eller vilken behandlingsregim (kontinuerlig/sekventiell) som används.Metoden som användes var en litteraturstudie som omfattade sju studier om HRT och bröstcancerrisk, vilka hämtades från databasen PubMed.Utifrån undersökta studier kan man dra slutsats att ökad risk för bröstcancer associeras med kombinerad östrogen-progestagen HRT jämfört med HRT med enbart östrogen och framför allt om man jämför kontinuerlig kombinerad HRT med sekventiell kombinerad HRT med ett dos-responsförhållande som bakomliggande grund. Progestagen-typ kan ha effekt på risken för bröstcancer men detta behöver undersökas ytterligare..

SammanfattningSyftet med den här litteraturstudien var att ta reda på vad det finns för möjligheter och svårigheter att producera ål i fångenskap. Med nya hållbara metoder att föda upp konsumtionsål skulle utfiskningen av glasålar minska i världen och man skulle kunna fortsätta äta den goda rökta ålen med gott samvete.Det finns välutvecklade metoder för att inducera könsmognad hos han- och honålar. Detta utförs genom att injicera hormoner och man kan därför fråga sig om det är hållbart i en produktion för framtiden. Efter kläckning av larverna finns flera viktiga faktorer att ta ställning till, så som utfodring och optimal hållning av ålarna. Även ägg- och mjölkekvaliteten spelar en stor roll när det gäller att hålla ålarna vid liv.Abstract The aim with this study was to find out how far we have come to develop reproduction strategies in eel culturing.

Background: Many elderly are feeling lonely and insecure in their homes; it?s difficult for them to cope with their life situation after discharge from hospital. There is therefore a need to get a deeper understanding of their situation and the need for action, thus possibly preventing a new hospital admission. Recent research shows that a better coordination is necessary when elderly are discharged from hospital and that the quality of the discharge is essential for how they cope at home afterwards.Purpose: To get a deeper knowledge of older people´s experiences associated with frequent readmissions to hospital.Method: A qualitative research approach was used trough interviews with open questions. Ten persons with an age of 75 years and older who had a readmission to hospital within one month was interviewed.

Diabetes mellitus is an endocrine disorder affecting a range of different mammals, including dogs, cats, horses and humans. Worldwide, 347 million people have diabetes, and the disease is an increasing burden on the world?s poorest countries. The disease is characterised by chronic hyperglycaemia and afflicted individuals experience increased thirst, polyuria and weight loss, sometimes despite increased appetite. Diabetes mellitus is either insulin dependent or non-insulin dependent.
