The effect of additional nitrate and sulfur in the diet on the methane production in cattle

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

Målgruppsanalys inför en samhällsintervention riktad till förskole- och skolbarn: Intag av livsmedelsgrupper som utgör fokus i interventionsåtgärder

Denna kartläggning ingår som en del i ett större forskningsprojekt, Idefics (Identification and prevention of Dietary and Lifestyle?induced Health Effects in Children and Infants) som har tagits fram för att förebygga övervikt och fetma bland barn mellan 2?4? och 6?8 år i Europa. Syftet med vår kartläggning är att utifrån ett stickprov bestående av 100 barn ur Idefics population kartlägga livsmedelsintag. Detta som underlag för deras kommande intervention där två av nyckelbudskapen är att öka konsumtionen av vatten samt frukt och grönsaker. Även skillnader i livsmedelsintag mellan interventions? och kontrollgrupp, flickor och pojkar samt förskole? och skolbarn studeras.

Aktiv rehabilitering med fokus på isokinetisk träning för nyopererade knäprotespatienter : En pilot studie på en rehabiliteringsklinik i Schweiz

En knäprotes förbättrar ofta livskvalitén för de som har levt med långdragna smärtor. Oftast är det patienter med artros eller reumatiska besvär som får en ny knäled, i synnerhet de som har hotad gångförmåga. Operationsresultaten är ofta mycket goda utifrån smärtlindringsaspekter men många patienter har bestående kraft och funktionsnedsättningar i den nya leden. Aktiv rehabilitering har visat goda resultat för dessa patienter. Vad gäller tidig styrketräning däremot finns det mycket få studier.

Visualisering av basalcellscancer med Tissue Viability Imaging - ett icke-invasivt diagnostiskt alternativ

Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer. It can be divided in different subtypes. The most common type is superficial and is most frequently occurring on the trunk and on the face. In severe cases it can be difficult to differentiate basal cell carcinoma from other skin tumors, therefore a skin biopsy is conclusive diagnostic method. In terms of treatment, curettage is a common non-surgical treatment of basal cell carcinoma.

Avledning av öringsmolt (Salmo trutta) från turbinintag

Vattenkraftstationer, med dammar och turbiner, utgör hinder för nedströmsvandrande smolt. Syftet med denna studie var att undersöka turbindödligheten för öringsmolt (Salmo trutta) vid två kraftstationer, de befintliga ytlänsarnas avledningseffekt och om effekten kunde förstärkas genom mörkläggning i form av övertäckning av kraftkanalen med en presenning vid turbinintaget. Utöver detta var avsikten även att undersöka om det fanns något samband mellan smoltgrad och smoltens förmåga att förflytta sig mot havet. I Emån i Småland fångades 46 öringsmolt som radiomärktes och sattes ut vid två kraftstationer och pejlades dagligen i sex veckor. Det var en större dödlighet vid den övre stationen än vid den nedre.

Sjuksköterskors upplevelser och attityder av att vårda kvinnor som gör planerad abort

Bakgrund År 1974 framförde svensk författningssamling abortlagen som gav kvinnan rättighet att genomgå en legal abort fram till graviditetsvecka 18. Abort innebär avbrytande av havandeskap som genomförs av två metoder, medicinsk och kirurgisk abort. Sjuksköterskan har en stor roll inom abortprocessen som innefattar tidsbokning, rådgivning, administrering av läkemedel, smärtlindring och efterkontroller.Syfte Syftet var att beskriva sjuksköterskors upplevelser och attityder av att vårda kvinnor som gör en planerad abort.Metod En litteraturstudie har gjorts för att kunna göra en sammanställning om de studier som finns inom ämnesområdet. De tillämpades elva artiklar varav nio av dessa var kvalitativa och två av dessa var kvantitativa. Artiklarna som valdes till studien kvalitetsgranskades enligt Forsberg och Wengströms (2008) beskrivningar och analyserades med hjälp av deras beskrivningar på hur man analyserar vetenskapliga artiklar.

Utilization of different habitatsin Colobus angolensis palliatus in the forests of Diani Beach, Kenya

The Angolan black and white colobus monkey (Colobus angolensis palliatus) is an arboreal primate that inhabits coastal forest fragments on the south cost of Kenya and is consequently vulnerable to forest fragmentations. The study was carried out in March and April 2011 in Diani Beach in Kenya where two of the largest populations of the species are distributed. This study is a pilot study to test methods for a Master?s thesis. The aim was to investigate any variations in use of two habitats of C.a.

Utvärdering av AOT för ett pilotskaligt, recikulerat akvakultursystem för fiskodling

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Utveckling av ett frågeformulär för delaktighet : En pilotstudie

Background: The need for structured practice has in recent years appeared in connection with the request for a more evidence-based nursing. In psychiatric care with its complex disabilities, it is important to have methods to identify these. Research has demonstrated the importance of patient participation in nursing that has been shown to affect their mental health. It is essential to get to know how patients with mental illness are capable of involvement in their life situation. The ICF emerged as a useful theoretical framework for development of questionnaires of patient participation.Aim: The aim of the present pilotstudy was to develop and test a questionnaire for participation, based on ICF.

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.

Torkningstekniker i den preoperativa handdesinfektionen - en experimentell studie

ABSTRACTIntroduction: Preoperative hand disinfection aims to prevent surgical site infections. After the preparing hand wash, drying is performed using an aseptic technique. It?s important to dry hands thoroughly in order to achieve the full effect of the alcohol based hand disinfection. Due to the lack of a evidence-based guideline on this procedure, the hand drying techniques differ among operating theatre nurses, depending on which technique seen as the most appropriate.

Carbon Critical Masterplanning tool : klimatpåverkan från samhällsplaneringsprojekt

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area. The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle perspective is applied.

Utvärdering av Di35M-PrLO-projektion av armbågsleden för utlinjering av mediala processus coronoideus hos hund :

The aim of this study is to evaluate an alternative projection of the Medial Coronoid Process (MCP) of the canine elbow joint. The projection (Di35M-PrLO) was, to my knowledge, first mentioned in an article by Haudiquet et al in 2002. In that article the projection was tested in vitro, and a good sensitivity was showed for the Medial Coronoid Process. The projection might be helpful in cases of suspected Fragmented Coronoid Process (FCP) . This study is divided into three parts. The first part is an in-vivo test of the projection, including technique and subjective evaluation of the outlining of the MCP.

Optisk undersökning av dieselsprayer från en höghastighetsroterande insprutare

There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.

Sjuksköterskans erfarenhet vid omvårdnad av familj vars nyfödda just fått diagnosen Downs syndrom

Introduction: About 160 children with Down syndrome are born each year in Sweden. They will spend their first time in life at the neonatal departments around the country. Previous research has shown that parents in these situations have experienced an unsatisfying behaviour from the caregivers and that they are not getting the care they desire. However the research that reflects the nurses? role in these situations is sparsely studied.
