Within insect communities, the population ecology of organisms representing higher trophic levels, for example, hymenopterous parasitoids, may be influenced by the structure of their insect hosts. Using microsatellite markers and ecological data, we investigated the population structure of the specialist braconid wasp parasitoid, Lysiphlebus hirticornis Mackauer attacking Metopeurum fuscoviride, a
This bachelor’s thesis aimed to investigate what drives the conversion of music from TikTok to streaming services amongst TikTok users. The study is based on marketing funnel models, such as AIDA and the simplified funnel including the three steps: awareness, consideration, and conversion. From these three steps, an ACC model was formulated that included awareness and consideration as independent
Reducing plastic waste incineration is crucial for Sweden’s transition to a carbon neutral society in 2045. To achieve this goal, it is essential to increase the material recycling of plastics. The availability of recyclable plastics depends on the private individual’s participation in sorting their plastic waste at the municipal recycling centres. Currently, the sorting quality of the rigid plast
Background: Abdominal surgery for cancer carries a high risk of venous thromboembolism, but the optimal duration of postoperative thromboprophylaxis is unknown. Methods: We conducted a double-blind, multicenter trial in which patients undergoing planned curative open surgery for abdominal or pelvic cancer received enoxaparin (40 mg subcutaneously) daily for 6 to 10 days and were then randomly assi
Cytopore is a bead-shaped, macroporous and easily compressible cellulose-based anion-exchange material intended for cultivation of anchor-dependent animal cells. Reticulated vitreous carbon (RVC) is a strong, non-compressible, high voidage (97%) matrix material that can be cut to desired geometrical shapes. Cytopore and RVC were combined to cylindrical composites (25mm 10mm) fitted inside chromato
There has been much debate on the topic of whether stricter environmental regulations can promote environmental performance and economic performance at the same time. Different researchers have used different indicators to measure environmental performance and economic performance in their empirical studies. However, it is a surprise that few studies have checked the relationship between environme
In this work we investigated the ability of a series of amino acids to act as cloud condensation nuclei using a static thermal gradient diffusion type cloud condensation nucleus counter. Particles of pure dry l-glycine, glycyl-glycine, l-serine, l-methionine, l-glutamic acid, l-aspartic acid, and l-tyrosine were studied as well as internally mixed dry particles containing ammonium sulfate and one
A general introduction to the status of the European Spallation Source ESS AB is given. As well as a general overview, the status of instruments and instrument design is presented. Particular attention is given to the instrument selection process, and how a proposal for a fundamental neutron physics beamline should be submitted. The contents of this presentation closely reflect the recently comple
The Common Cuckoo Cuculus canorus is an obligate brood parasite and many studies have dealt with egg rejection by host species. However, evidence for ejection of Cuckoo nestlings by host parents has not been reported. Here we describe an observation of a Skylark Alauda arvensis pair that probably ejected a young Cuckoo and subsequently raised their own offspring. This was the only case we detected
As intermittent faults in distribution grids continue to cause unplanned outages, grid owners face increasing challenges related to reliability, restoration times, and maintenance planning. These challenges not only affect customers but also result in higher operational costs and resource demands for grid operators. The purpose of this thesis is to develop methods for proactive fault management b
A commonly discussed issue among professionals in human service occupations, such as healthcare workers and social workers, is Secondary Traumatic Stress (STS). This phenomenon occurs when one is exposed to others' trauma and, in turn, becomes secondarily traumatized. The risk of experiencing STS can be reduced through strong organizational support combined with various strategies that individ
Sekundär användning av e-hälsodata är ett viktigt steg i att direkt och indirekt stärka vården, både inom Sverige och EU. Inom kort förväntas den uppmärksammade EU-förordningen om ett European Health Data Space (EHDS) antas. Genom förordningen kommer ett gemensamt hälsodataområde skapas vilket bland annat möjliggör sekundär användning av uppemot 450 miljoner EU-medborgares e-hälsodata för exempelvSecondary use of e-health data is an important step in directly and indirectly strengthening healthcare, both in Sweden and the EU. The anticipated EU regulation on a European Health Data Space (EHDS) will create a common health data space, allowing for the secondary use of the e-health data of up to 450 million EU citizens for research, innovation and decision-making. This has the potential to re
Currently, many Global South countries face an unprecedented debt crisis with large portions of their spending going to debt repayments. This financial restrain hinders their capacity to address basic needs and ecological challenges, particularly as climate change exacerbates vulnerabilities. To provide a solution for this, The Nature Conservancy (TNC) launched their Nature Bonds Program aimed at
The ancient Greek myth of Orpheus and Eurydice has been of interest to readers and writers across the ages. However, Ovid's version and many subsequent retellings have focused on Orpheus' character. H.D.'s poem "Eurydice" and Margaret Atwood's poem "Orpheus (1)" are two of the first revisions of the Orphic myth from Eurydice's perspective. In this essay, I c
