Mjölkningsfrekvensens påverkan på mjölkproteinets sammansättning och kvalitet :

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.

Jämförelse mellan sådd och naturlig föryngring av tall i Härjedalen

The purpose of this study was to compare naturally regenerated Scots pine (Pinus sylvestris (L.)) against seeded Scots pine in terms of benefits and differences. An inventory was performed at a number of different sites, 4 ? 6 years after soil scarification and data on the number of new established plants, their height growth as well as ground-line diameter was collected. Information about site conditions such as altitude, quarter exposure and frost risk was also collected. A review of previous studies was conducted in addition to the field study.

Cassava as an additive in biomass fuel pellet production :

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

COMPARATIVE STUDY OF HYDROLYSIS PERFORMED WITH MODERN MICROWAVE TECHNIQUE AND THE TRADITIONAL METHOD

Proteins are vital to all cells in the body. They consist of long chains of amino acids. To be able to study the amino acid composition of a protein it is necessary to hydrolyse it, followed by separation and quantification. When the protein is hydrolysed, in this case ß-lactoglobulin, the protein is divided into individual amino acids. The method that traditionally has been used to hydrolyse proteins takes 24-72 hours to complete.

Tree species traits response to different canopy cover for 34 tree species in an enrichment planted tropical secondary rain forest in Sabah, Malaysia

Tropical rain forests only cover around six percent of the world?s land area and contain around 70 % of the world´s animals and plants. Tropical rainforests have been, and still are, negatively affected by human activities. These activities lead to forest degradation which has negative impacts on production and biodiversity. Between 1970-1980 forests in Borneo, Sabah, Malaysia, was subjected to intense logging.

Förändras mjölkens proteinsammansättning i separata juverdelar i samband med höga celltal (SCC)? :

Today the milk production per cow is increasing but the milk delivered by the Swedish farmer contains less amounts of fat and protein than earlier. The contents have decreased since 1993. In average the milk contain 4,2 percent fat and 3,4 percent protein. Earlier the fat content in milk was important. Nowadays the dairy?s attention has turned to the milk?s valuable proteins, principally the caseins, which have a considerable nutritional value and are important for several dairy products like cheese and yoghurt.

Flottledsåterställning i norra Sverige: : effekter på habitatkvalitet och populationstätheter av juvenil öringar (Salmo trutta L.)

In an effort to evaluate the effects of restorations of float ways on population density of stream dwelling fish in relation to the changes in habitat, I studied the physical habitat restored and channalized sites and their population density of brown trout (Salmo trutta L.) in three streams in the municipality of Sorsele. The differences between the channalized and the restored sites where most noticeable regarding substrate which where generally coarser in the restored sites. The analyses showed that the proportion of habitat that where suitable to the age class 0+ where significantly lower in the restored sites compared to the channalized sites. Regarding age class ?2+, no statistical differences in habitat quality were found.

Adiponektins inverkan på lipidackumulation hos makrofager och skumceller

Bakgrund- Ateroskleros är idag den främsta orsaken till kardiovaskulär sjukdom och orsakar mycket lidande för individen och stora kostnader för samhället. Cytokinet adiponektin utsöndras av fettcellerna och har en bred anti-aterogen effekt. I den aterosklerotiska sjukdomsutvecklingen är lipidackumulation och prolifiering av makrofager till skumceller av avgörande betydelse. Syftet med detta litteraturarbete är att undersöka adiponektin inverkan på lipidackumulation och makrofagprolifiering samt se genom vilka verkningsmekanismer detta kan vara möjligt.Metod och resultat- Artiklarna till denna studie har hämtats från artikeldatabasen PubMed. Resultaten visar att adiponektin framgångsrikt hämmar lipidackumulation via adiponektinreceptorerna AdipoR1 och AdipoR2.

Utvärdering av ett mikroalbuminuritest till hund :

The occurrence of small amounts of albumin in urine, microalbuminuria (MA), is used both in human- and veterinary medicine as an indicator for patients who have developing proteinuria. Proteinuria can be prerenal, renal or postrenal which is important to establish during an investigation. With conventional methods decreased renal function is not detected until 70 % of renal function is lost. The ability to detect and start a treatment earlier might reverse or slow the progression of disease. The purpose of this study was to investigate the reliability of Heska® E.R.D.-Health Screen?, a test for microalbuminuria in dogs, to detect albuminuria.

Akustisk mätning av U-värde

This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions: ? Can U-value theory be combined with acoustic theories? ? Can the coefficient of heat be affirmed trough an acoustic measurement? The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units. The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory. The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

Trastuzumab som adjuvant behandling avbröstcancerpatienter med HER2-positivitet : Hur effektivt är det?

Breast cancer is the most common tumor disease among women in Sweden. About 7000persons, having a median age of 65, are diagnosed each year with this disease. Withmammography screening, breast cancer can be detected in an early stage which improves theoverall survival (OS). 20-30 % of the breast cancer tumors are overexpressing humanepidermal growth factor receptor 2 (HER2), which is a protein that stimulates cell proliferation.Trastuzumab (Herceptin®) is a humanised monoclonal antibody that targets the HER2-proteinand prevent the signals for cell proliferation.Trastuzumab has earlier been used for treatment of metastatic breast cancer. In the year of 2007trastuzumab was approved for adjuvant treatment of patients who has been medicated withsurgery and/or radiation.The aim of this study was to investigate the effects of adjuvant treatment with trastuzumab inHER2-positive breast cancer patients.

Visuell utvärdering av frekvensmodulerat raster på obestruket papper.

This thesis investigated if a combination of increased under colour removal (decreasing the total ink limit), normal andincreased density and modern FM-screening could be used to provide a visually better print on uncoated and coated paperin comparison with AM-screening using the same conditions.Two different test groups (one with graphic background, the other with no graphic background) were asked to a visuallyassess the quality of the prints presented in a pair comparison using a reference image.The results show that the FM-screening did not obtain any significant visual difference in comparison with AM-screening,regardless of paper types and density levels. In general however, prints on coated paper were graded higher..

Inverkan av SPC på induktion av protein AF och produktionsresultat hos slaktkyckling

This study was a degree in Master of Science in agriculture with specialization in animal science for the Department of animal nutrition and management at SLU. The subject was created by AS-Faktor, a small company for science and development within the company Lantmännen AB. It was a test of the effect of SPC (Special Processed Cereals) on induction of the endogenous protein AF (an antisecretory factor) in plasma and intestinal lumen in broilers. Previous results have shown positive effects on different intestinal diseases in pigs, horses, dogs as well as in humans. Beside the induction we also studied the effects on results in a conventional slaughter chicken production, including the ability of SPC to compete with or be affected by the coccidiostat, Salinomax.When diarrhoea occurs, it's because there is an imbalance between the secretion and the absorption and it can be caused by for example toxins.

Fåglar i urbana miljöer : kvaliteten på urbana habitat och om beståndstäthet är ett bra mått på habitatkvalitet

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

Skattningar i gallringsskog med hjälp av flygburen laserskanning : beräkningar med massaslutenhet

This master?s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The study area was in the municipality of Älvsbyn (Latitude 65° 40´ N, Longitude 21° 00´ E), in northern Sweden.The Swedish authority Lantmäteriet is currently laser scanning most parts of Sweden, providing new opportunities and applications. The primary aim of the national laser scanning is to create a new elevation model, useful in consequence analysis of climate changes.
