Faktorer som påverkar Vänerns öppna sandstränder och möjligheterna för hög biologisk mångfald ? med mossor som indikatorer på igenväxning
The sandy beaches of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of the beach, wear and grade of exposure. The purpose of the investigation is to control the beaches grade of overgrowth and find out which external factor is of most importance for the maintenance of the biotope. The results show that the beaches environment is affected by the slope of the beach, grade of exposure, size, wear and overgrowth.
Är reducerad jordbearbetning ett alternativ? :
Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage.
In this paper we have tried to find out if reduced tillage is an alternative for farmers.
Värdepapperisering av samhällsfastigheters hyresflöden : En attraktiv finansierings- och investeringsmöjlighet för att bygga vård- och äldreboenden till en åldrande befolkning?
The number of elderly people has been steadily rising in Sweden for a long time and as a proportion of the population, the increase has been even greater. The population structure in the country means that in the not too distant future, there will be a sharp rise in demand for care and elderly accommodation.A tighter credit market as a consequence of new rules and regulations with a stricter capital and liquidity requirements combined with market turbulence, has made financing property developement more difficult and more expensive which has resulted in many companies using alternative sources of finance.DEmand for safe investments with low risk is high as the market is volatile and banks, pension funds, fund management and life insurance companies are looking for investments outside the stock market that can deliver a safe return in the longer term. There has also been a debate about whether institutional investors as the AP pension funds really should own properties directly.As properties for care and elderly accommodation are definable assets with predictable payment flows, long leases and often a local authority as tenant that would not risk cancelling payments, these would be highly appropriate for securitisation, i.e. to issue bonds or other tradable securities based on the cash flows from the assets.In other words, the securitisation of rent flows would offer the opportunity to create an attractive investment product of the type being demanded, well suited to institutional investor requirements, while at the same time, it can provide an attractive financing opportunity to meet the need for more care and elderly accommodation..
Havsöringens (Salmo trutta) och laxens (Salmo salar) lekområden och lekvandring i Vindelälven och Piteälven :
The population of seatrout and salmon are threatened by over-fishing in the sea
and loss of spawning and growing habitats caused by logging activities in many swedish
rivers. The knowledge of the spawning migration and the habitat use of the seatrouts
and salmon are limited. This study analyse the upstream spawning migration of Atlantic
salmon and sea-running brown trouts from the lower part of the rivers to their spawning
sites in the rivers Vindelälven and Piteälven. A knowledge about the distribution of
spawning sites in the rivers will help these fish population in future restoration programs.
In the fishladder at Norrfors in the river Umeälven were 29 sea trout and 20
salmon radio tagged and subsequently released and followed during their spawning
migration upstream Vindelälven. They were tracked on their position in the river once a
week.
En man och hans ?pplen: en fallstudie av Carl Str?mbergs ?ppeltr?dg?rd
This bachelor?s thesis studies Carl Str?mbergs ?ppeltr?dg?rd, a private garden consisting of a large number of apple trees and varieties. The garden is located outside ?rebro, in N?rke, and is owned by a unit owner association whose goal is to preserve and determine the varieties. Through interviews, articles, site visits and documents from Carl Str?mberg, the purpose have been to get an understanding of who Carl Str?mberg was, how he collected the apple varieties and how that process was affected by the climate amongst apple growing and pomology during that time.
Sverige 2112 : Ett narrativ om hur arkitekturen kan utvecklas om världen går igenom stora förändringar på grund av klimatförändringarna. En linjär och vertikal stad.
Om världen till följd av klimatförändringarna blir mycket varmare kommer förutsättningarna för hur vi planerar städer, infrastruktur och jordbruk helt att vändas upp och ner. De delar av världen som idag står för världens livsmedelsproduktion kommer vid bara några graders förändring bli obrukbara som betes och odlingsmark. Dessa förändringar kan komma att starta konflikter, och stora flyktingströmmar som tillsammans med förändrade klimatzoner helt kommer att rita om världskartan. i Skandinavien är det då troligt att vi behöver bygga samhällen och städer för miljontals nya immigranter, och detta samtidigt som vi befinner oss mitt i den mest fruktbara jordbruksmarken i världen. Om hundra år måste vi dessutom, oavsett detta, dubbla livsmedelsproduktionen globalt sett.Vårt samhälle blir allt mer rörligt och infrastrukturen utvecklas i allt snabbare takt.
Faktorer som bidrar till respektive hindrar nytta vid elektronisk journalföring
This study was carried out in the purpose of investigating the factors in the electronicmedical records system in Procapita that contributes to utility for the users and the factorsthat prevents the experience of utility for the users. The study was done within KalmarCounty and its employees within the field elderly care. The problem that we brought upwas that the elderly part of the population is growing quite rapidly whilst the gap betweensupply and demand on nurses and physiotherapists is increasing. This creates a problem ofits own in regards to how we are going to care for the elderly when there?s not enoughstaff for it.
Ayatollah Khomeini : De rättslärdas styre
A large part of the Iranian population resented the west, in particular USA and Great Britain, during the Islamic revolution in Iran 1979. The people were also resenting the adverse effects of the trumped up frame made in Iran. The last shah of Iran, Mohammad Reza Pahlavi was detested by many in Iran for its west-oriented regime. The resentment among many Iranians is a consequence of the violations of e.g. the lack of political and civil rights, there were no existing legal security in the society, there were no economic distribution and the regime of Mohammad Reza Shah violated the human rights.The resolution from an Iranian perspective for riot is not new, during the last centuries the abomination against the despotic kings have been existing varyingly and big riots have been raised. The Islamic revolution in 1979 was new because the revolution added adverse effects of west, the population detested west and expressed it by protesting through demonstration. The significance of the revolution in 1979 was also attributable to Islam.
Barns flerspråkighetsutveckling : Hur föräldrar till flerspråkiga barn tänker kring flerspråkighet i hem och förskola samt hur deras tankar och upplevelser tas tillvara på förskolan
The purpose of our study is to interpret and understand the experiences that parents to multilingual children have towards multilingualism in pre-school. We are also interested in finding out what these parents think about their children?s development in multilingualism both in pre-school and at home. Our study is based on qualitative interviews. We interviewed nine families that have multilingual children in pre-school. The data we collected from our interviews has been analyzed using socio-cultural and inter-cultural theories along with previous research. The result of our study showed that parents to multilingual children have both positive and negative opinions about the multilingual concept. Most of our informants had positive opinions about multilingualism in general.

Subjektiv och objektiv bedömning av underlag på svenska hopptävlingar på elit- och nationell nivå
Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.
Powerplay En studie om de stora sporternas numerära överläge i svensk press

In the analysis we have studied the two national Swedish newspapers Dagens Nyheter and Aftonbladet. In doing so we have created two synthetic weeks in each of the years 1986, 1999 and 2012.
Republicans in the White House - Hard times for Soft Power? En teoriprövande studie om skillnaderna i soft power mellan demokratiska och republikanska administrationer
According to many scholars America's soft power is in decline, a power resource whose importance has been increasing in world politics. This makes it interesting to examine if there is a difference between how Democratic and Republican administrations wield their soft power.This thesis is a hypothesis-testing study and the purpose is to test the hypothesis that Democratic administrations, to a greater extent than Republican, can create, utilize and defend soft power. My thesis is based on Joseph Nye's theory of soft power and the focus of this study is the aspects of the foreign policy resources. In order to measure this concept I have made my own operationalization where five different indicators serve as my guidance. I use the method of least likely-cases to select and motivate the administrations being tested, which gives me a comparative study of the Democratic administrations of Lyndon Johnson and Bill Clinton and the Republican administration of George H.
Grödans kontra odlingssystemets effekt på frilevande nematoder
Nematodes are perhaps the most common animals in the world. Nematode populations can reach densities up to several millions per square meter in the soil. There are many factors which affect nematode communities in arable soil with respect to diversity and population size. Factors like tillage, crop, fertilization, nutrient status and moisture in the soil all have an impact on soil biology and in this way also have effects on the nematode community. This study is based on three different parts, soil samples taken in March 2012 and March 2013, soil samples taken monthly during the growth season of 2013 in bare fallow plots and a pot experiment.
Sambanden mellan inandningsbara, grova och fina partiklar i luften och strokeanfall i Malmö
In the western world, strokes are the third most common cause of death, hitting mainly the elderly population. Smoking, high blood pressure, diabetes and overweight are known risk factors for causing strokes. Previous studies show that an increased level of particulate matter, PM, is also related to an increased number of strokes. The population in this study consists of patients over 65 years old who live in Malmö. Levels of particulate matter were measured from October 2004 to April 2005 at a central outdoor monitoring site in Malmö.
