Hur landskapskvalitet påverkar humlors födosök efter pollen Under de senaste århundradena har det skett en nedgång i både antal arter och individer av humlor. Den förmodligen viktigaste anledningen till detta är den förändrade landskapsstrukturen som uppstått till följd av intensifieringen av jordbruket. Detta har lett till större och mer enformiga fält, samtidigt som naturliga (och halvnaturligaBumblebee abundance and diversity have been declining in the last few decades. Habitat change, mainly due to intensified agricultural practices, has been pointed out as the main driver in this process. Being central place foragers bumblebees are highly dependent on the landscape surrounding the nest and the resources available there. According to the optimal foraging theory bumblebee individuals i

After hatching, bird chicks are inevitably exposed to the thermal conditions of their environment. For the first stage of development chicks are not yet fully capable of maintaining a stable body temperature. During this time, their thermal environment can cause morphological and physiological priming. The plasticity of these responses and the extent to which they persist in the long-term is not w

Self-recognition is an advanced cognitive ability that is traditionally investigated by the mirror mark test. However, it has been argued that this test might not be a reliable measure of self-recognition ability, as it may be affected by the mirror understanding of the species. The great tit (Parus major) is one of the many avian species that did not succeed in this test. However, it has never be

Bumblebees are essential pollinators of wild and cultivated plants. They have experienced global declines over the last decades mainly due to habitat loss and fragmentation caused by agricultural intensification and land use changes. Haplodiploid hymenopterans with single-locus complementary sex determination (CSD), such as bees and bumblebees, are likely to experience partly different consequence

Allelopathy is a term first introduced by Hans Molisch in his 1937 book titled The Influence of One Plant on Another: Allelopathy and, as it stands, it is defined as the biological phenomenon through which growth, development, reproduction or survival of an organism are altered by the release of biochemicals from another. In this study, we investigate the allelochemical potential of leachates coll

The primary (acute) haemosporidian infection has the greatest negative effect on an individual’s fitness. Weak individuals are most likely eliminated from the population, while those that survive, develop a chronic infection when parasite infection intensity is kept at low levels with minor effects on the condition of the host’s life history traits. It is still unknown whether low levels of haemos

In a standard mass spectrometry workflow, acquired mass spectra are searched against a library of peptides to extract peptide spectra matches (PSMs). Peptides are normally quantified by aggregating the intensities of fragment ions extracted from MS/MS spectra. However, quantifying peptides by summing up the intensities of all fragment ions in PSMs can resulting in inaccurate results due to the fac

Abstract Bakgrund Telefonsjuksköterskan i primärvården i Region Skåne huvudsakliga arbetsuppgift är att triagera patienten till rätt vårdnivå. 2010 utformandes kompetensbeskrivningen för telefonsjuksköterskor i ett steg för att belysa telefonsjuksköterskans behov av kompetens och kompetensutveckling. Trots att kompetensbeskrivningen har funnits i 12 år visar forskning på att telefonsjuksköterskan

Bakgrund: Ohälsosamma levnadsvanor ökar i samhället vilket kan leda till hjärt- och kärlsjukdom, cancer samt diabetes typ- 2. Tidigt förebyggande arbete kan förhindra uppkomst av sjukdom. Motiverande samtal (MI) är en metod som används för att motivera patienter med ohälsosamma levnadsvanor till förändring. Region Skåne initierade nyligen riktade hälsosamtal till 40-åringar för att förebygga ohäls

Death is a universal human experience, yet the ecological impact of the care and disposition of dead bodies is rarely considered, due in part to cultural taboos surrounding the physical reality of death and decomposition. If negative environmental consequences are to be limited, deathcare will need to adapt. Utilizing interviews with funeral directors from the United Kingdom, the United States and

Bakgrund: Trots hälsofördelar hos både mamma och barn sjunker amningsfrekvensen. Tidigare forskning har visat att trots intentionen var att helamma, så minskade amningen eller avslutades helt innan barnets sexmånadersdag p g a att föräldrar saknar stöd från barnhälsovården och att det emotionella amningsstödet ansetts otillräckligt. Studier om barnhälsovårdssköterskor erfarenhet av att ge emotione

A common problem in access control is piggybacking. This is when a person without authorized access sneaks closely behind another with access through a door. This thesis seeks to answer whether using radar is a viable solution when attempting to detect piggybacking. Detection will be made by classifying sequences of point clouds generated by the radar, using neural networks. The thesis compares tw

The aim of this study is to investigate how staff who work with persons with mental impairment living in supportive housing describe and reflect on the clients´ self-determination and which options and challenges they experience with respect to putting the intent of the Swedish act concerning support and service for people with certain functional impairments (LSS) regarding self-determination into

Abstrakt Bakgrund: Ohälsa bland barn och unga har ökat under de senaste åren och skolan är en betydelsefull plattform med möjlighet att identifiera elevers ohälsa i ett tidigt skede. Hälsosamtalet mellan skolsköterskan och eleven syftar till att främja hälsa och förebygga ohälsa hos eleven. Syfte: Syftet med studien var att belysa hälsosamtalet mellan eleven och skolsköterskan i årskurs fyra ur s

Lignin is found in all biomass and is an abundant natural source of aromatic compounds. It has the potential to serve as a renewable raw material for a variety of chemicals currently derived from fossil fuel sources such as muconic acid, an important platform chemical. Kraft lignin is a waste stream from the pulp and paper industry. Upon depolymerization of softwood-derived lignin, aromatic compou

Bakgrund: Klimakteriet är en fas som drabbar kvinnor mitt i livet med varierande symtom. Kvinnorna upplever klimakteriet olika beroende på kvinnans bakgrund, erfarenhet, kultur och sociala kontext. Klimakteriet är inte ett område som har så stort fokus i utbildningen till distriktssköterska, men som är ett viktigt område för den verksamma distriktssköterskan, utifrån hur vanliga symtomen på klimak

Limiting the global average temperature rise to 1.5°C above pre-industrial levels is a major task that that requires profound societal changes. Many agree that changes in culture are the way to tackle environmental problems. Several social movements and environmental activists have tried to use art as a tool to educate, engage community in participation of decision making, and strengthen community

The following paper examines the production of memory in Berlin Global, an exhibition housed at the Humboldt Forum in Berlin, through employing methods of discourse and narrative analysis. The analysis aims to deconstruct memories of the German Democratic Republic present in the exhibition and how these are integrated into greater national and international historical narratives through the use of

Kubernetes is a container orchestration platform growing ever more popular, and as the software industry shifts into the container cloud, security will become paramount. The Common Vulnerabilities and Exposures (CVEs) systems cata- log and provide references to known vulnerabilities. The goal of this thesis is to systematically evaluate the security situation of Kubernetes through common mitigatio

I dagsläget ligger byggbranschen efter många andra industrier när det kommer till effektivisering av metoder. Branschen är väldigt beroende av materialleveranser och att dessa sker utan störreproblematik. Det är viktigt att arbeta för att material anländer i rätt tid, rätt mängd och på rätt plats för att undvika förseningar och onödiga kostnader. Med ett stort intresse för effektivisering av byggIn the current situation the building industry is behind other industries when it comes to making methods more effective. The industry relies on deliveries of material and that these happen without trouble. It’s important to work towards material being delivered at the correct time, correct quantity, and the correct place to avoid delays and unnecessary costs. With a great interest in making the
