Utredning av överföringsledning : Förstudie av ledningsdragning för framtida VA-försörjning i Malungsfors
Introduktion: I nuläget är Röntgenmammografi det första valet vid bröstcancerdiagnostik och har en genomgående sensitivitet på 78- 85 %. Vid avbildning av tätare bröstvävnad sjunker sensitiviteten och specificiteten för Röntgenmammografi och antalet falska positiva resultat ökar, vilket leder till onödiga biopsier, Under 1990-talet utvecklades Breast Specific Gamma Imaging (BSGI) (Aktolun et al. 1992). BSGI är en teknik utvecklad för bröstavbildning. Tanken var att BSGI skulle komplettera Röntgenmammografi vid avbildning av tätare bröstvävnad. Studier från Palmedo et al.
Konsumtion av livsmedel rika på järn och folsyra samt attityd till de näringsämnena & en hälsosam kost under graviditeten
BAKGRUND: Folsyra och järn är två viktiga ämnen som under graviditeten har olika betydelser dels för mamman och dels för fostret. Brister på dessa ämnen kan således leda till skador av olika slag och därför rekommenderas ofta kosttillskott till gravida kvinnor. Kvinnornas matvanor kan påverka om de får i sig tillräcklig mängd av dessa ämnen.SYFTE: Syftet med denna studie var att se hur gravida förhåller sig till att ha en hälsosam kost under graviditeten samt inställningen till kosttillskott med järn och folsyra. Studien syftade till att undersöka eventuella hinder samt se användningen av järn och folsyra.METOD: Studien är av kvantitativ typ med en enkät som inför denna undersökning har modifierats, Health and Taste Attitude Scale. Enkäten består av 7 frågor och 21 påståenden varav 6 st är från HTAS och resterande tillagda.
Förekomst av Helicobacter spp. hos hund : samband med hepatit/pankreatit?
To date, the genus Helicobacter consist of 26 different species and even more species are yet to be characterized. Helicobacter has been detected in connection with diseases in the liver and pancreas in humans and animals.
Helicobacter spp. are gram negative, curved, S-shaped or spiral shaped bacteria. They are microaerophilic and have flagella that make them motile. Helicobacter, present in the gastric mucosa neutralize the gastric acid through production of urease that hydrolyses urea to ammonia and bicarbonate.
Granskning av drycker med hälsoprofil : påståenden och hälsomärkning
The aim of this study was to survey the labelling of drinks with pronounced healthbenefits found on the Swedish market today and to evaluate whether they are inaccordance to EU and national regulations or not. Especially the nutrition and healthclaims were looked into. This study shows that there are several drinks with claimedhealth effects being sold today. The process of approaching full functioningregulations in the EU on nutrition and health claims is proceeding slowly. A snapshotof today??s market of drinks with pronounced health effects shows that there aremultiple cases of misleading statements and interfering labelling on the products.Often it concerns nutritional labelling or health claims.
INVERKAN AV HAVSF?RSURNING P? PROTONERBARA ORGANISKA F?RORENINGARAS EKOTOXICITET
Resulting from anthropogenic carbon dioxide emissions, average surface seawater pH is estimated to decline from today's approximately 8.05 to between 7.78 and 8.03 towards 2100. For ionisable organic pollutants, changes in pH can lead to a change in the degree of ionisation, which could influence the ecotoxicity of a compound by altering its bioavailability. In this study, potential changes in ecotoxicity of ionisable organic compounds resulting from ocean acidification are examined. This is achieved partly by conducting a literature review, analysing existing literature that investigates this relationship. Potential changes are also evaluated by examining marine ecotoxicity data for ionisable organic compounds on the watch list pursuant to Directive 2008/105/EC of the European Parliament and of the Council, as well as on the list of priority substances according to the 2022 proposal for amending the Water Framework Directive (2000/60/EC).
Evaluation of transgenic lines of field pepperweed (Lepidium campestre L.)
The worldwide industrial demand of energy, often in form of fossil fuel, is continuously growing and at the same time these resources are coming to an end (Hamamre, 2013). The interest and focus in renewable sources are then more important than ever and plants are suggested to be a good
alternative for production of raw material for industrial purposes (Nilsson et al., 1998). But the world is also facing an increasing world population which also increase the nutritional needs, plants therefore need to be suitable for both industrial and nutritional purposes. To achieve this, common plants need to be improved but it also need new potential crops to be developed and introduced
(Carlsson et al., 2009). Modern technology like gene engineering is an important tool to achieve these challenges (Carlsson et al., 2011).
This work focused on analyzes and evaluation of different transgenic lines of field pepperweed (Lepidium campestre L.).
Genomförbara önskemål : kan elevernas önskemål gestalta skolgården?
Den intracellulära protozoon Neospora caninum är en viktig orsak världen över till abort hos nötkreatur. De exakta bakomliggande mekanismerna till abort är omdiskuterade och sambanden verkar vara komplexa. Immunförsvar hos såväl moder som foster har en roll i patogenesen. Denna litteraturstudie syftar till att se vilken roll immunförsvaret har under dräktigheten och vid uppkomst av abort till följd av en neosporainfektion. Många olika hypoteser kring aborterna har lagts fram och merparten av dessa visar att tidpunkten för när infektion sker är avgörande för utfallet av dräktigheten.

Emissioner i slutna utrymmen Med speciell inriktning på emissioner av formaldehyd och organiska syror
This study aimed to evaluate the levels of formaldehyde and organic acids that can build up within enclosed spaces. Another goal was to compare two types of paints that can be used as coating barriers within showcases and in turn compare them to the modern, and by many highly recommended, material of Marveseal®. A low volatile waterborne alkyd/acrylate paint and a two component polyurethane paint was compared to Marveseal® in two series of experiments. One series measured the level of formaldehyde, and thus the effectiveness of the three chosen barriers, and the other series measured the level of volatile organic acids, both the acids emitted from the paint itself, and that of the wood. One box in each series were not treated at all and was used as a reference.The fact that different types of materials emit volatile organic compounds have long been known.
Barley starch, structure and properties
Starch is a naturally occurring substance in most plants and is used as energy storage. It is a component that mainly consists of amylose and amylopectin. Together they build a complex pattern which gives starch its specific properties. The proportion of amylose and amylopectin varies in different plants but generally starch consists of 25 % amylose and 75 % amylopectin. There have been discoveries of barley varieties containing 100 % amylopectin called ?waxy starches? or ?waxy barley? as well as varieties that have a high content of amylose, around 70 % and these are called ?amylotypes?.
Fermented sausage : product development at Lindell's Gårdsslakteri
Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company?s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer?s needs and expectations and thereby be more likely to succeed. Lindell?s Gårdsslakteri AB is a local slaughter and meat processor in Västergötland.

The sample was specified by using specific keywords.Selection criteria: The criteria for inclusion of studies required that flaxseed oil was compared with a control and that blood pressure was measured as an endpoint.
Är kolrika jordar en källa till fosforläckage? : en sammanställning av data från 130 åkerjordar
Phosphorus (P) is an essential nutrient but a surplus could lead to eutrophication. Furthermore,
the minerals used to produce the mineral phosphate is a non renewable resource.
There are in other words several reasons to reduce the leakage of P and the agriculture is one important area to attend. The aim of this work has been to investigate if carbon-rich arable soils content contain more P than arable soils with low carbon content. Moreover it has been calculated if the carbon-rich soils could pose a risk of P leakage by comparing their delivery of P with the plant uptake. The work has consisted of compiling the results from former gathered and analysed soil samples of 130 Swedish arable soils.
The fractions of P considered are water soluble P (Pw), ammonium lactate-extractable P (P-AL), hydrochloric acid-soluble P (P-HCl), organic ammonium lactate-extractable P (Porg-AL) and inorganic ammonium lactate-extractable P (Porg-HCl).
The legacy of the mill : a metal polluted forest soil in Gusum
Soils in a metal contaminated site on Stångberget in Gusum in southeastSweden were investigated and compared to relatively unaffected soils a fewkilometres away. Pollution came from historical release of untreated flue gasesfrom a brass mill. The objective was to find information on how high the metalconcentrations are, if metals from the polluted soil affect the surroundings andif the metal contamination affects the microbial community. The soil wasinvestigated using several different methods, such as field XRF measurements,chemical analysis of metal, carbon and nitrogen content, pH, acid neutralizingcapacity, texture, soil depth, field leach tests, sequential extraction and microbialfunctional profiles. The study showed that copper and zinc concentrationswere above Swedish Environmental Protection Agency guidelines for lesssensitive land use on the entire investigated area.
Foderbetor och kogödsel som substrat för biogasproduktion; anaerob mesofil samrötning i labbskala
One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.
