I denna studie undersöks hur vattenmiljön förändrades i ett område av västra Yoldiahavet, idag sjön Myssjaren i östra Mellansverige. Syftet med undersökningen har varit att återskapa hur vattnets salthalt förändrades i området genom att studera förekomsten av fossil från saltvattenkrävande bentisk kalkskalsfauna i lera från perioden.Fossil hittades från sju år, 10 395-10 388 lervarvsår BP, av den 31 år långa period, 10 410-10 379 lervarvsår BP, som har undersökts. Utifrån fossilförekomsten kunde det konstateras att vattnet var bräckt under dessa sju år. Eftersom att fossil inte hittades från tidigare och senare perioder Därför är det möjligt att vattnet var bräckt både före och efter denna period.Det som begränsade de undersökta arternas utbredning i området var halten suspenderat sediment i vattnet. Det var en konsekvens av att mycket sediment transporterades till området i och med att området befann sig mellan två större utlopp av glacialt smältvatten.Därför har denna studie, förutom att konstatera att vattnet var bräckt under den undersökta perioden, även visat en succession av arter i Yoldiahavet.I studien identifieras också en 4 år lång kallperiod som varade mellan 10 393-10 389 lervarvsår BP.

The purpose of this study is to map out and to analyze the spatial variation of female representation at the national level in established democracies. The aim is also to explain the variation in the female representation. The main questions that the paper tries to answer are:1.How does women representation in established democratic parliaments vary?2.Why does women representation in established democratic parliaments vary?This study is a comparative and statistic study, i.e. a study that includes a bigger number of countries and where quantitative analysis methods are used in order to achieve comparative analyses.

Elephants are hindgut fermenters, which affects their diurnal rhythm. To reach their nutrient demands, elephants must eat almost constantly throughout the light part of the day. Sexual dimorphism may also affect their behavioral patterns. To understand the elephants' normal living habits and foraging behaviour, we conducted a pre-study in the Mara Triangle, the north-western part of the Maasai Mara National Reserve. Each of four to six observers randomly chose a focal animal within the group of elephants by the criteria that they were adults and visible.

The main aim of this research is to survey the general colour scheme for private dwellings inVisby, built 1860?1930. During this period the visual appearance of the town of Visby changedsubstantially, since the increased local production of lime led to the plastering of many woodenbuildings. Which colour schemes were chosen for the different building types of the historic centreof Visby, and which colours came to dominate the time period? The methods used for answeringthese questions have partly been field studies on site and sampling of selected buildings, andpartly critical reading and observation of iconographic material (paintings, drawings, aquarelles,postcards and photographs).

Depression är en vida utbredd sjukdom. Kognitiv träning skulle kunnavara en kostnadseffektiv och lättillgänglig intervention att bemötasjukdomen i ett tidigt skede. Tidigare forskning tyder på att kognitivträning har effekt på depression och kognitiva nedsättningar. Dennastudie ämnade undersöka om träning hemma skulle leda tillförbättringar av depression, och om dessa berodde på träningen i sig.Fyra deltagare med depressionssjukdomar genomförde träning medPaced Auditory Serial Addition Task (PASAT). Studien hade en n=1-design med för- och eftermätningar, och kontroll genompseudointervention.

Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.

The aim of this work is to examine methodologies at remedial lessons for children with weak mobility, in a common Swedish municipal school in an attempt to determine if a connection to theoretical learning exists.Kadesjö describes how difficulties in concentration can arise as a result of problems with mobility and perception, and according to Piaget very young children develop cogitation through physical movements. These connections are not news but always current.At the meeting with Lasse the question was born whether learning problems in school that are a result of concentration difficulties, could be countered with mobility training.By the selection of Life history as method, it?s possible to follow a physical educator's experiences through his 30 years of work, and to some extent even his private life. Experiences and results are notified from a historical perspective from 1976 until 2006.He is bringing us on a journey that shows the changes in methodology and results after his contact with Sensomotoriskt Centrum..

The intention of this study is to compare difficulties of Swedish pronunciation of five  second-language learners with Thai as mother tongue. Thereafter make a comparison with previous research in pronunciation difficulties in people with the same primary language to see if the deviations are similar. I used both recorded material/recordings which I analyzed as well as experiences from pronunciation training that I observed at SFI. The pronunciation difficulties were documented and entered in tables. The recordings consist of 25 Swedish words and a text performed by five informants. In my study, you can distinguish a pattern in my five informants pronunciation difficulties complying with Bannert informants who also have Thai as primary language.

Syftet med litteraturstudien var att utreda vilka kunskaper som finns rörande sambandet mellan högt hull hos kvigor innan könsmognad, och deras senare mjölkavkastning i första laktationen. Ekonomiskt sett så är uppfödningsperioden för kvigor en stor kostnad för mjölkföretaget och stora finansiella förbättringar skulle kunna göras på området. Stallplats och omvårdnad och kostnader för kvigan, foder är dock den största utgiften och står för 60 % av totala kostnaden för kviguppfödning. Genom en sänkning av ålder för könsmognad skulle även inkalvningsåldern kunna sänkas och föra med sig en kortare period som kvigan inte är produktiv. Könsmognadens start är sammankopplad med kroppsvikt och hull, inte ålder, så genom att höja utfodringsnivån kan inkalvningsåldern sänkas.

Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level. The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.

Background: 2007 there was 42 000 fall related accidents in Sweden and they are expected to increase the next few years. Fall among elders results in both increasing economically costs and suffering, but they can be prevented. For example has physical exercise shown an increasing effect on the risk for falls. Aim: The aim of this literature review was to investigate what influence Tai Chi has on the risk for falling among elder. Method: A literature review was conducted where eleven scientific articles were analysed with inspiration of the content analysis.

Undersökningen syftar till att jämföra två olika urvalssystem för officersprogrammet. För detta syfte ställs det gamla respektive det nya urvalssystemet mot kadetternas studieresultat. Urvalskriterierna till dessa urvalssystem korreleras mot studieresultatet i en korrelationsmatris. Därefter undersöks de uppmätta sambanden medelst semi-partiala korrelationsmått och konfidensintervall. Detta skapar belägg för att det föregående urvalssystemet var effektivare än den nya för att välja ut kadetter med förmåga att tillgodogöra sig utbildningen.

The aim of this study is to describe and analyse the knowledge of three of the treatment methods used in youth welfare and this is accomplished through a knowledge review. This study contains an analysis of three different treatment methods described in eleven different peer reviewed articles. The articles are all internationally published between the years 2006 to 2012 and they are all effectiveness evaluations. The articles deal with treatment methods concerning Motivational interviewing (MI), Aggression Replacement Training (ART) and Cognitive behavioural therapy (CBT) and these are three of the most common in youth welfare in Sweden. There is not much knowledge of Swedish conditions and that is why this study focuses on international research.

The spruce bark beetle (Ips typographhus) is one of the 25 000 species of insects in Sweden, an insect of great economic importance because it can alone terminate forest of high value. During the past decade, insights of climate change received with increasing attention. If the future brings a milder climate in the north and therefore a longer growing season, one would think that it would only affect the forestry to the better? Yet in recent time, outbreaks after storm felling seems to occur more frequently. The Spruce bark beetle ruins millions of cubic meter of Norway spruce (Picea abies) in Sweden alone, with more frequent storm felling and a larger amount of wind thrown threes in the forests there will also be room for an advancing reproduction.

This review paper summaries scientific research about horse thermoregulation and the consequences of using a blanket. Horse owners put blankets on their horses to protect them when they are clipped, to protect them from bugs, to keep them clean and so on. This can have consequences for the horse which their owners might be unaware of. I have tried to answer following questions by searching the available scientific literature; ? How can the horse maintain thermoregulation? ? Is there a risk of suffering when horses wear a blanket? ? Is there a risk of suffering when horses do not wear a blanket? ? How can animal inspectors estimate the welfare of horses when they wear or do not wear a blanket? My result shows that horses who wear a blanket have an increased risk of becoming overheated, develop a chafing, have an increased exposure hazard and have a restrained natural behaviour.
