Organic farming is promoted as a sustainable alternative to conventional farming, with positive effects on the diversity of plants and selected animal taxa. Here, we used a literature survey to collect presence/absence data on the composition of farmland bird, ground beetle, spider as well as butterfly and moth communities from 28 independent studies to identify genera and (sub-)families that had
The war in Ukraine in 2022 has caused environmental damages on different scales which come with their own challenges. One of the factors that can cause environmental damage is vegetation fire. As earlier studies have concluded, in conflict regions the amount of vegetation fires can increase due to (forced) migration, change in agriculture and warfare tactics. Not only conflict can change fire occu
Asymmetric warfare has gradually become a common occurrence in an increasingly interconnected world, as the interactions between militarily unequal adversaries grow ever more frequent. Because the strong do not always emerge victorious, which we presume they would, the following question is warranted: how can asymmetric warfare be understood? In other words: how are we to understand the processes
Uppvärmning av byggnader är en betydande del av Sveriges energianvändning, vilket gör värmepumpar till en viktig lösning för att minska både energibehov och klimatpåverkan. Prestandan beror dock på byggnadens utformning, isoleringsnivå och lokalt klimat. Tillverkares COP och SCOP värden är baserade på standardiserade test förhållanden som skiljer från svenska klimatet, vilket kan leda till överskaHeating of buildings is a substantial part of Swedens energy use, making heat pumps an important solution for reducing both energy demand and climate impact. However performance depends on building design, insulation and local climate. Manufacturer COP and SCOP values are based on standardized test conditions that differ from Swedish climates which may lead to overestimated efficiency. This thesi
Rapid population growth, climate variability, and limited hydrogeological data create uncertainty for groundwater decisions in Rwanda. Kadiridimba catchment was selected as a case study to develop a groundwater model, test what can be concluded under these constraints, and identify the measurements that most strengthen confidence in the results and assumptions. The aim was to develop and evaluate
This thesis has investigated the municipal urban project Warszawska Dzielnica Społeczna (WDS) in the district of Wola, Warsaw, Poland. WDS was a city initiated urban project presented in 2019. The project has not been realized. When speaking to city officials, it remained unclear as to why. Therefore, it was found interesting to investigate why the organization that initiated the project, did not
The use of technology, specifically machine learning, to address complex issues in developing regions has become increasingly prominent. In the context of wildlife conservation, combating poaching has emerged as a significant application of such technology. This research project aims to develop machine-learning-based low-cost antipoaching solutions. It presents three case studies, each exploring a
Food availability is known to influence animal distribution and abundance, playing a crucial role in population dynamics. However, this correlation remains somewhat unclear due to interactions with several other factors such as climate, predation pressure, competition, or even human influence. Therefore, understanding the mechanisms underlying these processes is crucial for ecologists to effective
The current Japanese population of 124 million is expected to decrease to 104 million by year 2050 (Takahashi et al., 2003) with a rapid aging population and, thus increasing immigration is one of the responses to this demographic concern. Hereon onwards, it will be relevant to understand the social patterns of foreign residents living in Japan and finding out more about their livelihoods as non-n
Teachers’ experiences of school leadership behaviour and the social contexts in which these have taken place interest me. I aim to identify and understand what Swedish secondary school language teachers’ reflections are on what they require in terms of leadership from their principals in different contexts in order to gain personal job satisfaction. The objective is that this research can then fun
Populärvetenskaplig sammanfattning: Examensarbetet syftar till att undersöka hur klimatiska förändringar och mänskligt utnyttjande av marken har påverkat fluviatila våtmarker (våtmarker i anslutning till rinnande vatten) i Bräkneåns dalgång i mellerst Blekinge. Få liknande undersökningar av fluviatila våtmarker har tidigare gjorts i Skandinavien, varför det är av intresse att ytterligare undersökaThe objective of the present investigation was to study how climatic changes and human impact may have affected fluvial wetlands in a river system. There are few earlier investigations in Scandinavia of that kind. Palaeoecological and palaeohydrological investigations were carried out in two fluvial wetlands located in the valley of the river Bräkneån. The main site Björkeryd is situated somewha
Recent reports focusing on virulence factors of periodontal pathogens implicated proteinases as major determinants of remarkable pathogenicity of these species, with special emphasis on their capacity to modulate complement activity. In particular, bacteria-mediated cleavage of C5 and subsequent release of C5a seems to be an important phenomenon in the manipulation of the local inflammatory respon
The impacts of climate change are likely to exacerbate many problems that coastal areas already face. In this study, we used multinomial logistic regression to examine human perception of climate change based on a cross-sectional survey of 1253 individuals in coastal regions of Tanzania. This was complemented with time series analysis of 50-year meteorological data. The results indicate that self-
III-V Nanowires (NWs) grown with metal-organic chemical vapor deposition commonly show a polytypic crystal structure, allowing growth of structures not found in the bulk counterpart. In this paper we studied the radial overgrowth of pure wurtzite (WZ) GaAs nanowires and characterized the samples with high resolution X-ray diffraction (XRD) to reveal the crystal structure of the grown material. In
Given a capacitated telecommunications network with single path routing and an estimated traffic demand matrix, we aim to determine the routing path of each traffic commodity such that the whole set of paths provide an optimal network load balancing. In a recent paper, we have proposed a column generation based heuristic where, in the first step, we use column generation to solve a linear programm
Abstract The endangered minnow Iberochondrostoma almacai is an endemic Iberian cyprinid with a restricted and fragmented distribution. Here, we describe the genetic structure of the species and infer its demographic history from six nuclear-encoded microsatellite loci and mitochondrial cytochrome b sequences. Genetic diversity was low (microsatellite He<0.45; mtDNA π<0.0015), and both markers reso
The purpose of this paper is to provide insight into how companies work during packaging development to reduce negative environmental impact along supply chains, and to compare their practical approaches with the theoretical concepts presented in the literature. The research approach is explorative and based on nine cases in the food and manufacturing industries in Sweden. Data were collected from
The clitoris contributes to the normal female sexual response cycle. A significance of cyclic guanosine monophosphate (GMP) has been assumed in the control of clitoral vascular smooth muscle. As only a few investigations on the physiology of the vascular and non-vascular clitoral tissue have been carried out, knowledge on the mechanisms controlling this particular female genital organ is still vag
Mucosal pathogens trigger a local innate host response by activating epithelial cells. Bacterial adherence and Toll-like receptor 4 (TLR4) signaling have been implicated as key events in this process. This study addressed the molecular basis of the epithelial response to gram-negative infection in the human urinary tract. Mucosal biopsies were obtained from kidneys, ureters, and bladders of patien
New food products are constantly put on the market. Today the focus often lies in creating nutritional and sustainable products to reduce the environmental impact of the product in question. One example of this is the approval of the yellow mealworm, Tenebrio Molitor, as a novel food in the European union. To efficiently include the protein fraction of the yellow mealworm into food formulations, k
