Diel vertical migration (DVM) is performed by various zooplankton taxa. The general movement pattern of DVM has been well studied while the possible clonal differences of this movement largely remain unknown. My master thesis focus on investigating the effects of environmental stressors on Daphnia magna strains isolated from natural populations. Here I maintained 11 strains of Daphnia magna origin
The social network analysis is a method on studying social relations which is becoming more and more popular on the arena of social science. This thesis examines, in the perspective of sociology of law, how well the above mentioned method can be used on studying criminal networks which are specialized on narcotic crimes. The basic idea for this thesis is that criminal networks are often based on t
According to the Convention on the Rights of the Child (CRC) in all actions concerning children, whether undertaken by public or private social welfare institutions, courts of law, administrative authorities or legislative bodies, the best interests of the child should be a primary consideration (CRC article 3 p. 1). However, it is not regulated in the law or in CRC what is considered to be the ch
The purpose of our essay was to examine what treatment women have had, who in their teenage years had eating disorders, how they have experienced this treatment and how they live today. Our central questions were; what was their experience of the treatment, how are their lives today, has the eating disorder and the treatment affected how the women live today and what kind of treatments are there?
Good insect monitoring is important for both disease vector control and e?cient usage of pesticides in farming. Entomological lidar has been proven useful for detecting and monitoring insects. For every insect that transit the laser beam a backscatter signal containing species-specific information is obtained. Esti- mating the fundamental wing beat frequency of an observation is important for dete
Detta examensarbete behandlar en energieffektivisering av Örebrogatan 2A-C i Kv. Hallonet som Helsingborgshem äger och förvaltar. Genom att ge förslag på olika åtgärder för att få en sänkt energianvändning på den idag energislukande byggnaden är förhoppningen att arbetet ska kunna användas som underlag i en framtida renovering av byggnaden. Byggnaden från 1954 består idag av 20 lägenheter fördeladThis thesis is about an energy efficiency improvement of Örebrogatan 2 in Kv. Hallonet that Helsingborgshem owns and manages. By giving suggestions for different actions to get a reduced energy consumption on the today energy-wasteful building is the hope that the work and the conclusions can be used for a future renovation of the building. Whilst Sweden is growing with many new buildings, there a
Tidewater glaciers on Svalbard are sensitive indicators of climate change and play a crucial role for Arctic ecosystems. The widespread retreat of tidewater glaciers across Svalbard highlights the need to quantify retreat rates and project when these glaciers will become land-terminating. This study investigates tidewater glacier retreat during historical (1936–1990) and present (2012–2024) period
Migration does have a time, energy or mortality cost, and the strategy to minimise the costs shapes the migration behaviour. Depending on the relative influence of these costs in shaping the migration, an animal is expected to undertake these journeys in different ways, depending on their morphology and migration ecology. I investigated if five Tringa-type waders minimise their migration time, and
Krig och konflikter världen över har lett till ett ökat intresse för och behov av försvar. Förhörssituationer har tidigare färgats av inhumana tillvägagångssätt och tortyr för att bryta motstånd hos den förhörde och få relevant information trots att tidigare forskning har visat att dessa metoder är ineffektiva. Denna studie syftade till att undersöka hur effektiv användning av olika förhörsteknikeWar and conflicts worldwide have increased both the interest in, and the need for defence. Historically, interrogation contexts have been characterized by inhumane approaches, such as torture, aimed at breaking resistance and obtaining information, despite previous research, demonstrating the ineffectiveness of such methods. The aim of this study was to examine how the effective use of different i
The purpose of our study was to explore what it is like to have a distressing near-death experience (NDE) and the aftereffects that follow. Positive NDEs have previously been more extensively studied, whereas research about distressing NDEs is still lacking. There have only been a handful of studies that have used qualitative methods to study both distressing and positive NDEs. We accessed all dis
Sweden is considered one of the most prominent countries for gender equality, with relatively high levels of female board members at publicly listed companies. However, the EU Law on Gender Balance on Boards implemented in 2022 adds pressure for Sweden to maintain, and improve, gender distribution on boards since Sweden was able to opt out of the law. There is a lack of research on the topic for S
Brain Computer Interfacing is a sprawling scientific field, with many competing designs in use or being tested. The goal of this project was to compile information about Utah Arrays, Michigan Probes, Neural Lace (also known as Mesh Electronics), Neuralink and Stentrode, and compare the positives and negatives of each design. Of especial interest were the parameters of material, number of electrode
Studien undersöker på vilket sätt pedagoger och barn i förskolan kommunicerar kring musik. Syftet med undersökningen är att ta reda på vilka ord och begrepp som används i musikarbetet på förskolan och primärt i sångsamlingen och hur sångsamlingen organiseras. Genomförandet av studien utgår från två olika sätt att samla in data, observationer och kvalitativa intervjuer. Sångsamlingarna på förskolanThe study investigates how educators and children in preschool communicate about music. The purpose of the survey is to find out what kind of language and which words are used in the music work at the preschool, primarily when they sing together in Singing time and how Singing time is organized. The implementation of the study is based on two different ways of collecting data, observations and qua
This study was done to gain an understanding of the importance of 12 water sources that are in the Vomb biosphere reserve. To do so, an ecosystem services analysis that included the four following types of ecosystem services: provisioning, supporting, regulating, and cultural services, was conducted. The ecosystem services analysis was done by using indicators for each service. A final score base
Within the software industry it is now common to use the freemium business model; giving away the core product for free while charging for additional premium features. A risk for companies adopting the freemium business model is that the percentage of paying customers is not high enough to both subsidize all the free users and make profit for the company. This thesis investigates how the design o
Despite the fact that there are established networks that reach far beyond the ¨last mile¨, there are still difficulties encountered by the distribution networks of necessities in Uganda. The purpose of this thesis is to study how successful networks in Uganda operate, what characterizes them and under what possible conditions they could be used for distributing humanitarian supplies. The method f
This essay conducts a semiotic analysis of four Walt Disney Pictures films, two from the 1990s and two from the past decade. The films were selected based on their release periods and shared narratives. The first two films analyzed are Vaiana from 2016 and Pocahontas from 1995, chosen for their focus on independent female protagonists. The other two films, En annorlunda värld from 2022 and Lejonku
Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. These regions may be identified by hypoxia, given that radiobiological research has demonstrated a significant correlation between oxygen leve
This thesis explores how Salesian Institutes are related to religious peace-building in post-colonial and post-conflict Cambodia. It examines if and how the Catholic-Salesian multi-religious educational mission system is able to peacefully co-exist in a Buddhist Cambodian society, and collaborate with other minority religions present – Protestant, Muslim, and non-religious in promoting education f
