Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Gudsbilder i svenska visor Fröding/Karlfeldt/Vreeswijk

Charles Hartshorne (1897-2000) was a religious philosopher. He adopted and developed the cosmologic thinking and concept of God from the philosopher Alfred North Whitehead, he was also influenced by Heidegger, Spinoza and other philosophers. According to Whiteheads religious philosophy Hartshorne claimed that there is a dualistic transcendence within the Godhead. A dualistic transcendence where one unity/transcendence of God is abstract, outside the creation and time and therefore is eternal. The other unity (or transcendence) is inside time and creation and closely in process to it .

Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

ATP bioluminescence to establish a test procedure for hygiene testing of liners and tubes on farm level : an investigation of the effect of ageing on the hygienic status of rubber liners and tubes

When rubber equipment in a milking system ages, physical and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly. Formation of biofilm in milking equipment could in turn cause bacterial contamination of bulk tank milk. ATP bioluminescence is a fast and easy way to determine the hygienic status of a surface based on its ATP content, and results are given in relative light units (RLU). The method measures both bacterial contamination as well as residues from other organic material.

Vi tror på Gud Fader allsmäktig. En studie av Charles Hartshornes processteologi i jämförelse med luthersk teologi

Studier av koppar i mjölk : en prooxidant med negativa effekter på mjölkkvaliteten

The taste of the dairy product is probably the main factor determining consumer?s dairy products choice. Consequently it is of great importance that the product tastes good and as expected every time. Off-flavors in milk can be caused by for example oxidation of the milk fat. Since copper is a prooxidant, a high copper content in the milk can cause oxidation.

Kvinnan i historien?

Bedömning av estetiska ämnen har varit ifrågasatt gällande dess kvalité, rättvisa, funktion och hur det påverkar ämnet och individen. Studien syftar till att beskriva bedömning av det estetiska ämnet Visual Arts vid en lärarutbildning i Sydafrika presenterat ur ett lärarperspektiv. Forskningsfrågorna utgår från ämnesdidaktikens teori gällande Vad bedöms, Hur kommuniseras bedömningen och Varför görs bedömningen. Metoden som använts är ett två månaders fältarbete vid en bildlärarutbildning där jag följt tre lärare och deras arbete genom deltagande observation, samtal, intervjuer och insamling av vissa dokument.Det empiriska materialet har analyserat från de tre didaktiska frågorna. Resultatet visar att lärarna, som var utbildade konstnärer lade ned mycket tid och engagemang på bedömning.

Mångkulturell bibliotekariekompetens - En litteraturstudie och intervjuer med bibliotekarier och chefer vid Malmö stadsbibliotek.

The title of this Master´s thesis is Multicultural librarian competence - a literature study and interwievs with librarians and managers in Malmö Public Library.Every fifth Swede is born abroad or has at least one parent who are. The migration flows of today reach out longer, there are more efficent ways of communication and travel. This has made previously ethnic homogeneous populations as the swedish more and more hetergeneous. Library services to inmigrant users started out as a specially directed activities. The political view of migration has changed over the years and the current perspective is the one of mutual integration and cultural diversity.

Det obetydliga : om fiskhuvudformiga hängen, sociala praktiker och förändring, 600-1200 e. Kr.

Fish-head pendants are one of the characteristic Gotlandic Late Iron Age artefacts. This object has been rather neglected and mainly considered as an insignificant embellishment, normally worn as a neck-collar and seen as an artefact include in the typical Gotlandic set of female jewellery.The fact that the fish-head pendant has a very long life span, which stretches from grave-finds in the Early Vendel Age to hoards in Viking Age as well as secondary usage as brooches in the Early Middle Ages, makes the artefact an excellent starting point for discussions on social practices and change through material culture. It's shown in this study that, contrary to previous beliefs, the normal usages for fish-head pendants is as solitary pendants and not as neck-collars. Neck-collars is shown to have an intricate relation to inhumations for young individuals, whereas solitary pendants are found in cremation deposits for adult individuals, something that relates to a fixed social practice mainly in the period 700-900 AD and that develops from the cremation funeral practice. This particular social practice relates to aspects of attraction and protection and continues in to the 10th century outside of funeral structures, which is shown by the composition of hoard-finds from the 10th century, but is totally absent when the pendants is given a secondary usage as brooches in the end of the 11th and beginning of the 12th century.

Kan ett ökat intag av omega-3- fettsyror påverka testosteronnivåer hos kvinnor med PCOS?

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Can an increased intake of omega-3 fatty acids have an effect on testosteronelevels in women with PCOS?Author: Ylva Dernbrant och Helene HagenborgSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundPolycystic ovary syndrome affects women of fertile age and consists of elevated testosterone levels and increased insulin resistance along with effects on ovulation and fertility. The elevated level of testosterone often leads to problem with acne and hirsutism, and it is also common with overweight and metabolic syndrome. The nutrition treatment has mainly consisted of energy restriction, together with exercise and drugs to reduce insulin resistance and consequently reduce androgen levels. However, an in-depth knowledge about how the components of our diet can affect further, is lacking.Omega-3-fatty acids can affect insulin resistance and testosterone levels within other groups but today knowledge is lacking if these findings can be transferred to women with PCOS.

Alternativa levnadssätt - Moderna nomader ? Travellers ? det irländska resandefolket

Are different ways of life possible in a world that increasingly becomes "Westernized" or globalized? This study examines and analyzes the diverse and complex way of life that includes socioeconomical nomadism as the Irish Traveller community are availing themselves of on the island of Ireland. In a broader perspective the study of the Travellers is put in context to how modern society emerged, and what characterizes the contemporary western societies. This is to understand the way Travellers nomadic lifestyle has been constrained and how the interrelationship between the dominant society and the extended family group constituting Travellers social composition has affected their livelihoods. Their social role is considered from two identification points ? home and work.Nomadism as a phenomenon, its history, expression and possible motives are being described in this work.

Miljöarkeologi i Umeå stads hamn och slagfältsarkeologi på Krutbrånet : Två fallstudier inom historisk arkeologi i Umeås 1800-tal

This master thesis deals with two case studies in environmental archaeology and battlefield archaeology focusing on two major events in the late history of the Swedish coastal town Umeå and its nearby village Sävar. Established in the early 1600's, Umeå was known for its export of timber and import of cereals. The town has suffered from numerous fires, the fire in 1888 being the most devastating. Few written records of the town remain from before the 1900's. The latest war in Sweden's history is documented in historical sources and took place at Krutbrånet, Sävar where the Swedish troops suffered defeat against the russian forces in 1809.
