Stokastiska processer f?r modellering av cellpopulationer: Simulerad cell?ldrande och f?ryngring p? populationsniv?
I den h?r rapporten till?mpas tv? f?rgreningsprocesser, en diskret tid Galton-Watson och en
kontinuerlig tid Markov f?rgreningsprocess, i syfte att studera hur en population av ?ldrande
celler utvecklas beroende p? populationens celldelningsf?rm?ga och delningshastighet, d?r
?ldrandet ?r direkt kopplat till ackumulering av defekta proteiner. Vi kollar ?ven p? effekten
hos cellens ?ldrande baserat p? hur k?nsliga de ?r f?r defekta proteiner. Populationens delningsf?rm?ga
har en avg?rande effekt p? hur v?l populationen v?xer och bibeh?ller ett l?gre
antal defekta proteiner hos cellerna, med dessa f?ruts?ttningar ses ytterligare effekt baserat p?
delnigshastigheten hos cellerna.
Idiopatisk epilepsi hos hund
ABSTRACT
Epilepsy describes a neurologically caused condition which involves seizures. Epilepsy can be classified according to different types of causes and the nature of seizures can vary. Medication for epilepsy in dogs is limited in comparison with human medicine.
Idiopathic epilepsy is the most common neurological disease and one of the most common genetic diseases in dogs. Because epilepsy has a higher prevalence in certain breeds, there is reason to suspect that it is a hereditary disease.
The inheritance of idiopathic epilepsy is for most breeds not determined, except for a few variants of the disease.
Vad görs? : En studie om föräldrasamverkan på språkintroduktionen på två gymnasieskolor i Stockholms län
The purpose of this examination paper has been to examine the situation for Swedish as a Second Language Programs in relationship to their interaction with the parents of the stu-dents. This case study was performed at two schools in the county of Stockholm. A com-parative analysis of both national and local documents for school governance was used to analyse the contents for incidents of parental involvement in schooling. Furthermore, qualitative semi-structured interviews were carried out with five staff-members holding key positions. The findings of the study are that schools tend to practice parental involve-ment only to the level that it is recommended in the national documents.
Användande av avskjutningsstatistik i förvaltning : påverkar tidigare jakt CPUE?
In fisheries, there is a long tradition to use catch data when evaluating changes in the stock and effects from harvesting. It is a common practice to use Catch Per Unit Effort (CPUE) as an index of population size, and several studies have investigated the properties of CPUE in relation to population abundance, spatial distribution and efficiency of gear. In research, catch rate on trap-transects is used as an index of abundance for wildlife species but CPUE is rarely applied as a tool in harvest management.In 1993, more than 60 000 km2 of the state managed mountain range in Sweden was opened to the public for small game hunting, under the responsibility of the county administrative boards in Jämtland, Västerbotten and Norrbotten. The total area is now divided into 332 hunting units (median=73 km2) and an internet based system is used to administer licences and reporting bag statistic. Each hunter has to register the results within two weeks after the hunt.

Undersökningen sträckte sig över veckorna 41 ? 47, 2003 och genomfördes via enkäter i utvecklingsarbetet ?Processkrivning?. Som bakgrundsmusik användes de två genrerna: populär- och klassisk musik.
Non-Identity. Att undkomma ett moralfilosofiskt moment 22
Can we harm future people? According to our commonly used contractarian theories, it seems we cannot. This is because our actions of today not only influence what they are supposed to influence, but also who mates with whom and when, and thus which particular persons will ever live in the future. Had we not performed a particular action, the future people born as a result of that same action, would not have been born. It therefore seems they cannot reasonably reject our actions.
Åldrande i ett mångkulturellt samhälle : En kvalitativ studie av äldre invandrares tillgång till samhällsinformation och deras deltagande i aktiviteter riktade till äldre medborgare.
In light of the European Union`s 2012 theme year: Active aging and solidarity between generations I wished to gain an understanding of weather elderly immigrant are provided with equal possibilities and access to local community information as the majority population and their participation in activities arranged for senior citizens in the municipality where they live. I have done this by meeting with those who work in this capacity. I also chose to meet with representatives for immigrant organizations in the local community to enquire of their work with senior citizens within their own ethnic group. This is a qualitative study on a phenomenological ground based on nine interviews and four observations. I have had two theories to help me analyze my empirical material.
En r?rspis: och hur den ?r uppbyggd
This thesis researches the construction of the Swedish masonry heater called r?rspis.
A r?rspis has an inner smoke channel system that stores heat and it was developed in the
early 19th century alongside the Swedish kakelugn (tiled stove). Unlike the tiled stove,
the R?rspis was commonly found in simpler environments and is part of the cultural her itage of the rural population.
Ett vikande befolkningsunderlag i en kommun : ett problem eller...

Informanterna som medverkar är politiker, tjänstemän samt representanter från näringslivet. En kommun ingår i studien, det är Finspångs kommun i Östergötland. Uppsatsen undersöker hur dessa ser på frågan om ett vikande befolkningsunderlag. Hur man resonerar kring fenomenet och hur samspelet och samverkan mellan aktörerna uppfattas.
Hur långt bär cykeln? : Gång och cykling i Västerbottens län - en studie av pågående arbete med regional gång- och cykelplanering
The craft of planners are planning for a better future. Knowledge about climate change, environment, health and availability effects the trend towards less car dependent societies in favour of public transport and active transport like walking and biking. This study takes place in Västerbotten, one of Sweden?s most north provinces with a population of 260 000 inhabitants. It is a sparsely populated area with two dominant cities, the other municipalities are largely unpopulated.
CANNABIS - EN KVALITATIV STUDIE OM HUR ANVÄNDNING AV CANNABIS KAN UPPLEVAS
The purpose of this paper was to examine how people experience the practice of Cannabis in daily life. The study was based on interviews with five individuals who have experience with cannabis use. They do not represent a bigger population only themselves. We chose these particular individuals because all of them began using cannabis at a young age- everyone before they were twenty. But they have been using cannabis because of different reasons.
Wetland development in the context of ecotourism : a conceptual design proposal for a wetland site in Lake Victoria, Kenya
The travelling sector is expanding worldwide, which puts all destinations under pressure to have a functioning
social system and good resources to manage the problems and take advantage of the opportunities that the
tourism sector can offer a community. The area around Kisumu in Kenya, like much of Africa, tourism can
simultaneously ensure a stable financial future while it removes, as a result of a growing population, more and
more of the scenery that many tourists want to experience. Responsible travel to natural areas that promotes
conservation of the environment and improves the welfare of local people is what defines ecotourism. A
concept that implies a closed cycle, where visitor?s needs are met in balance with what can be given back,
without risking creating imbalances in society.
Along the coast of Lake Victoria, valuable papyrus wetlands provide Kisumu vital ecosystem services
such as water purification, climate adaptation while it also serves as a reservoir for biodiversity.

Hur hanterar främlingskritiska partier främlingen inom statsgränsen? : En jämförande undersökning av partiernas minoritetspolitik och deras syn på nationella minoriteter
The debate about affirmative action for ethnic minorities in countries with another majority culture is growing bigger in many parts of the world. However, it is often the debate misses the aborigines within the countries? borders. The aim of this paper is to investigate the possible conflict in opinions for xenophobic political parties when managing an aborigine population. I will use a qualitative method to study the ethnic minority Sámi in Sweden, Norway and Finland, and afterwards xenophobic parties view on them.To reach a result will I present a scale over Xenophobia ? Cosmopolitanism, which is described as a political cleavage.
Hur påverkasogräsuppkomsten av jordbearbetning :
Today it is common to spray against most weeds by using very expensive weed-killers.
The goal for every farmer is to have as low costs as possible for their use of machines and weed-killers.
Therefore it is in everyones interest to find other methods to fight the weeds.
Finding a way to reduce the rise and growth of weeds already at the preparation of the soil would lower the number of laps over the field and also decrease the amount of weed-killing dose.
Tests show that by harrow in the dark it is possible to reduce the population of weeds with up to 60%, but the normal reduction would be about 20-30%.
To verify the results above we made tests by using two different methods of preparing the soil. We tested ploughing and harrowing in daylight and during night. Later we checked the number of different weeds in areas prepared in daylight and during night.
By studying the results from the different methods used we found a considerable reduction of some kinds of weeds in areas prepared during night..
