It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. Consumption of water that contains a high concentration of uranium implies a health risk due to the chemical characteristics of uranium. Livsmedelsverket (The National Food Administration) and Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that precautionary measures should be taken when the uranium concentration in ground water exceeds 15 micrograms per litre. In particular, drinking water collected from wells in areas with uranium-rich bedrock may have a harmfully high level of uranium. One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden, contains water that exceeds the guideline of 15 micrograms per litre. One interesting technique for removing uranium from drinking water is adsorption to reactive filter materials.

The conservation of great apes faces many challenges, one of which is the threat of infectious disease outbreaks. Zoonotic transmission of respiratory diseases from humans to wild great apes has recently been confirmed. Since respiratory disease is one of the major causes of death in both gorillas and chimpanzees, this gives reason for major concern. Little is known about the risks of disease transmission from humans to great apes in natural environments, and there is a need for systematic risk evaluation. Researchers, conservation staff and tourists spend time in very close proximity of wild great apes, sometimes during long time periods, which poses a potential risk of disease spillover. However, the presence of researchers and tourists has been shown to decrease the risk of poaching, making the matter increasingly complex.

PurposeThe purpose of this study has been to investigate the documentation process following the guiding principles of the Quality Norms for Fall Prevention concerning fall risk assessment, risk identification, fall preventive measures, information and the making of an individual care plan.MethodThis study is a quantitative, descriptive and retrospective journal review study. There were 100 journals examine the existing documentation concerning fall risk assessment of patients who received treatment in geriatric patient care. The sample was consecutively.ResultsThe results showed that fall risk assessment was documented in 79 of 100 examined journals. 56 (71 %) of the fall risk assessments were made within 24 hours. In 59 of 100 journals the patient, relatives or former caretakers was asked whether the patient had had a fall within the last year, and in 61 of 100 journals it was documented that the nursing staff had made an assessment that the patient was going to have a fall during his or her length of stay if no preventive measures were set in.The majority of fall risk factors and fall preventive measures were documented within the areas of walking and transfer. It was documented that the patient was informed of fall risk, fall risk factors and fall preventive measures in 15 of 100 journals.

In modern dairy production the milking frequency is increased in some herds due to introducing of automatic milking systems or the farmers decision to milk high producing dairy cows more than two times a day. With more frequent milkings the milk yield increases while the content of fat and protein decreases. However, how the composition of protein is influenced is not fully evaluated. The purpose of this study was therefore to see if a higher milking frequency had any impact on the milk production and especially on the protein composition. This study was conducted as a half udder experiment.

Syftet med denna litteraturstudie var att beskriva riskfaktorer som påverkade uppkomsten av trycksår samt de vanligaste förekommande preventiva åtgärderna. Vidare var syftet att beskriva sjuksköterskans roll vid förebyggandet samt behandlingen av trycksår. De vetenskapliga artiklar (n=21) som ingick i studien söktes manuellt samt datoriserat via databaserna Blackwell Synergy, CHINAL, Elin@Dalarna och Elsiever. Inklusionskriterierna var att de skulle vara vetenskapliga samt av kvalitativ och kvantitativ design. Även litteraturstudier inkluderades.

Clinical signs of hypocalcaemia in dairy cows are easily recognized, and a rapid response to treatment generally confirms the diagnosis in the field. However, clinical signs of other disorders in cows, such as toxemia, calving paralysis, or muscoskeletal injury, may mimic those associated with hypocalcaemia. Therefore, making a diagnosis of hypocalcaemia on the basis of clinical signs alone may be difficult. In ambulatory veterinary practices, cow-side tests are useful to make the diagnosis and prognosis easier. Kruuse?s Kalcium Test is a cow-side test based on the principle that calcium ions are necessary for coagulation of blood, and that chelation with EDTA prevent coagulation.

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Livsstilfaktorer som inaktivitet, felaktiga kostvanor och rökning bidrar till utvecklandet av fetma, blodfettsrubbningar, typ 2 diabetes och högt blodtryck, och ökar risken för insjuknande i hjärt- och kärlsjukdomar. Syftet med denna studie var att utvärdera om en kombinerad tränings och kostintervention under 3 månader, följt av regelbunden uppföljning under ett år påverkar motionsvanor, hälsoupplevelse och riskfaktorer hos personer i riskgrupper. 151 medelålders kvinnor och män med riskfaktorer för hjärt- och kärlsjukdom randomiserades till en interventionsgrupp ( n =75 ) och kontrollgrupp ( n = 76 ) och genomgick undersökning vid baslinjen, efter 3 och efter 12 månader. 123 personer fullföljde studien. Efter 12 månader sågs signifikanta förbättringar inom interventionsgruppen av vikt, BMI, midjemått, höftmått, midjehöftkvot, triglycerider, HbA1c, syreupptagningsförmåga, systoliskt och diastoliskt blodtryck till skillnad från inom kontrollgruppen.

Bakgrund: Hot och våld är inom akutsjukvården ett allvarligt arbetsmiljöproblem som ökar såväl i Sverige som i resten av världen. Ambulanssjukvården är ett område inom sjukvården där förekomsten av hot och våld är som mest framträdande. Ambulanspersonalens vårdrum varierar och därför kan det vara en utmaning att skapa en säker arbetsmiljö. Syfte: Syftet var att ur ett prehospitalt perspektiv beskriva vilka åtgärder som kan vidtas för att kunna förebygga hot och våld inom akutsjukvård. Metod: En litteraturstudie med systematisk sökning och beskrivande design användes.

Psykosocial ohälsa är en av de största orsakerna till sjukfrånvaro bland tjänstemän. Få studier syftar till att undersöka förebyggande aktiviteter för stress på organisationsnivå. Europeiska arbetsmiljöbyrån, EU-OSHA, erbjuder råd för att på företag förebygga stress. Syftet med detta examensarbete var att beskriva hur tjänstemän upplevde EU-OSHA:s råd för organisatoriska stressförebyggande insatser. Undersökningen sökte svar på om råden upplevdes genomförbara, om det fanns hinder som försvårade genomförandet och vilka förutsättningar som krävdes.

The progress of the health among the elderly has a major meaning for the needs of care, nursing and social services. The health of the elderly has improved but fall and fall accidents are a major problem. Acute diseases, activities and environment risks are often related to fall accidents. The aim of the study was to describe health care staffs? opinions about fall risk and fall prevention.
