The role and genetic control of non-coding RNAs in bacterial infection
Promoters are genetic elements that facilitate the transcription of a gene and they have been found in front of non-coding RNA (ncRNA) genes in different organ-isms, e.g. the model plant Arabidopsis thaliana. A similar element, DUSE, has been found in front of ncRNAs in the social amoeba Dictyostelium discoideum and a part of this project has been to analyze the function of this putative promoter element through cloning and expression studies. A construct to analyze the func-tion of DUSE was successfully designed and introduced into D. discoideum but full expression studies were not finished because of shortage of time.
På uppdrag av Allah - En studie av legitimiteten i den saudiarabiska statsapparaten
Since 2003 Saudi Arabia is under attack from domestic Al Qaida-cells which, by random shootings of westerners and bombings of compounds and official state buildings, is trying to challenge the stability of the royal regime. According to Al Qaida, the Royal family is attacked because of their friendly relations to the US and for not implementing Islam in the Saudi society as profound as they ought to. Political analyst finds it obvious that the Islamic Al Qaida-cells by terrorism is trying to erode the stability in the kingdom.An important foundation for stability for any government is legitimacy. The aim of this thesis is to examine the royal legitimacy strategy in the state bureaucracy of Saudi Arabia. The question at issue is: how has the royal family constructed the civil, military and religious bureaucracies to maintain and promote stability and legitimacy?The thesis focuses on the on three different units within these three bureaucracies and it surveys the way they are staffed and organized to strengthen and maintain legitimacy for the royal family.

Solenergi på Nya Karolinska Solna
In today?s society climate change has grown to one of the largest global issues. To reduce emissions of greenhouse gases, large changes of the energy system are required. An increasingly popular solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction of solar energy has been studied, solar thermal collectors to meet the need of heating and solar cells to satisfy the need for electricity linked to operating the hospital building.
En retrospektiv fallstudie av konservativ behandling av intraartikulära hovbensfrakturer, typ II och III, hos rid- och körhästar :
Hospital records of 32 non-racehorses referred to Skara Animal Hospital and Halland Animal Hospital, Sweden, between January 1995 and September 2001 for intraarticular fractures of the third phalanx, were reviewed, and follow-up information on final outcome was collected to determine whether any injury or treatment factors could be associated with the outcome. Mean age of the horses was 8.3 years (range, 1-20 years), and follow-up time ranged from 1 to 7 years after injury. In 11 (34%) of the horses, injury involved the front limbs. Twenty-two (69%) horses returned to their original level of use. There was no statistically significant correlation between outcome and elapsed time from injury to treatment, treatment variables, or bony union in the present study.
Rangordningens inverkan på beteendet hos nötkreatur (Bos taurus) och dess konsekvenser för djurtillsynen :
Extensively kept animals for meat production have the right to live in a good
environment. Cattle (Bos Taurus) as social animals live in small herds in the
wild. When holding animals extensively new problems have arisen regarding
human ? animal interactions. One welfare problem is to be able to come close
enough to the animals to investigate their health condition.

Inga hästar men gärna fred : Nationell norm och lokal kulturpolitik, exemplet Växjö 1975-1996
The aim of this paper is to analyze the influence that aristocrats in Sweden had on the Swedish movement for the prevention of cruelty to animals, and why especially aristocrats started it. The sources I have been using are speeches and texts written by persons who were involved in the movement. I have also studied rapports from the three largest societies for the prevention of cruelty to animals. In the sources I looked for terms, expressions and opinions that can be paralleled whit the aristocratic ideal and opinion. Things that can relate to aristocratic urban people.
Advantages and disadvantages of different observation methods on a troop of wild olive baboons at a river in Southern Kenya
Every observation method has its advantages and disadvantages and a well-adopted method gives more reliable results. Factors affecting the choice of the most appropriate methods for recording foraging behaviours include species, group size, environment, seasons and age. The focus for this study was to determine which method is most appropriate for studying the foraging behaviour of a troop of 89 olive baboons (Papio anubis) living in a riverine forest by the Southern Ewaso Ng'iro River by Lale'enok Resource Centre in Kenya. To determine this, a literature study was carried out to compare methods from monkeys and apes. I found instantaneous sampling was the most common method with intervals of 5 minutes in most cited studies.

Med hunden i fokus - en metod att identifiera hundars användningsområde utifrån det postkraniala skelettet
AbstractThis is a study of present day dogs with the purpose to establish a method to investigate archaeological dogs and determine their use in the past. The study has focused on measurements of five bone elements, scapula, humerus, radius, ulna and femur. A principal component analysis has been applied in order to decide which measurements to be further used in the analysis. Different proportions have been calculated on these measurements.A test to try the method has also been done on bones of a wolf and a dog without known background. The results from the different elements are positive, and they narrow the field down to two dog types of which one is more likely to be true than the other.The final results show that, although over lapses between the four different dog groups; hunting dogs, guard/work dogs, sled dogs and shepherd's dogs exists, it is possible to distinguish different dog usage from the proportions of the bones..
Hund i vården : Fysiska, Psykiska och Sociala effekter av arbete med vårdhund
Background: Pet therapy has existed as a concept since 1964 when the American child psychologist Boris Levinson coined the term. Nowadays Animal Assisted Activity (AAA) and Animal Assisted Therapy (AAT) are both recognized concepts, and with progressed research the science of pet therapy increases.Purpose: To summate the most recent science in pet therapy (therapy dog) research with focus on physical, psychical, and social effects.Methods: Literature study/review with descriptive design, research on 21 articles published from year 2003 and onward. Articles used in the study were chosen through beforehand decided criteria, subject to quality rating, and summated in an overview. The main results were summated and presented in similarities and differences.Results: The main result of the summation was that important results could be measured in each of the three fields of research. Physical/physiological effects: pain relief, differentiated results on vital signs, and increased activity.
Hundar som hjälpmedel i vård och terapi. En studie om djur som hjälpmedel i behandlingsarbete.
Syftet med denna studie var att undersöka hur djur, med fokus på hundar, används som
hjälpmedel i behandlingsarbete samt vilka effekter användningen av hundar anses ha. Vi
fördjupade oss i de metoder som finns med djur som hjälpmedel samt studerade ett
exempel på ett behandlingshem där hundar används i vård- och terapisyfte. Genom en
litteraturstudie och en kvalitativ intervjuundersökning har vi fått svar på följande
frågeställningar: Hur kan hundar användas som hjälpmedel i behandlingsarbete och vilka
arbetsmetoder finns? Vilka fysiska och psykiska effekter kan användningen av hundar
som ett hjälpmedel i vård- och terapisyfte ha? Vad gör en hund till en bra vård- och
terapihund? Hur används hundar på en missbruksinstitution för äldre män? Resultatet
pekar på att hundar kan användas i vård- och terapisyfte genom användning av de
metoder som finns, det vill säga Animal-Assisted Activity, Animal-Assisted Therapy
samt Animal-Assisted Therapy in Counseling. Vad som gör en hund till en bra vård- och
terapihund är att den tränas på adekvat sätt, har ett bra temperament samt har en
hundförare som ser till klientens och hundens bästa.
Kraftanalys och framtagning av mätanordning för vertikala vindkraftverket Lucias bärarmar
The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.
Solenergi på Kvarnholmen
In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.
