The last mass-extinction event happened over 65 million years ago when an asteroid collided with earth, resulting in the loss of 76% of all species. Scientists now warn that we are on the precipice of a new mass-extinction, the responsibility of which can be placed entirely on one species, the homo sapiens. While some species of birds, bats, and arthropods are especially vulnerable, we are all int

Insektssamlingar hjälper oss att bevara stävmalarnas okända liv Många fjärilsarter påverkas snabbt och negativt när deras livsmiljöer förändras. Flera arter bland de undanskymda stävmalarna är idag därför mycket ovanliga, såsom hässlestävmalen, vars hemvist i en hasseldunge Öland idag är den enda i hela Norden. För att den biodiversitet de bidrar till ska kunna bevaras till framtida generationer,The historical record is an underutilised resource within many fields of biology, despite its unique uses. In this thesis, I have used information from entomological collections and species observation systems to investigate and elaborate on the distribution, habitat preferences and phenology of some rare and poorly known moths within the family of Gelechiidae. Like many other microlepidoptera, ge

EQUITY: The Center Of Inequality Awareness offers an alternative viewpoint of the Naturum. It'sa way of learning about your surroundings through engaging activities that center on inequity. EQUITY, which is situated next to one of Sweden's greatest lime quarry, feels strongly about its cause, which is the inequality the workers had compared to investors. I was inspired by the uneven and n

Examensarbetet Plats för fler i Lund undersöker möjligheterna och utmaningarna i att ge nytt liv åt en förbisedd urban plats. Projektet utgår från frågor om hur offentlig arkitektur kan främja en social blandning, hur kulturhistoriska värden kan influera en ny gestaltning och hur det omgivande stadsrummet kan användas som inspiration och ge indicier om vad som kan kompletteras i stadens urbana milThe thesis Room for More in Lund examines the possibilities and challenges of giving new life to an overlooked urban space. The project is rooted in questions about how public architecture can promote a social mix, how cultural-historical values can influence a new design and how the surrounding urban space can be used as inspiration and provide indications of what can add to the city’s urban envi

PLC-system (Programmable Logic Controller) är robusta realtidssystem som används för att styra fysiska processer i krävande miljöer. Moderna PLC-system är väldigt kapabla, men skulle systemet mot förmodan gå på knä, kan man alltid installera ännu ett PLC-system i mån av plats. En lyx som inte finns ombord på ubåtar, där man istället behöver hushålla med befintliga system. Med hjälp av två matematiThis master’s thesis is commissioned by SAAB Group with the purpose of developing a model which can be used to estimate the margin for expansion of devices in PLC systems. Although commercial PLC systems are hard real-time systems, they have inherited unpredictable characteristics due to off-the-shelves components. This makes it difficult to measure the impact on performance when a new device is c

Pack-bed framtidens medicintekniska diagnostik? Kroppens celler kommunicerar genom att skicka information till varandra via små partiklar. Genom att fånga in dessa kan man ta del av denna information och olika sjukdomar kan därigenom detekteras. I detta arbete undersöks Pack-bed, en ny teknik där akustik används för sådan infångning.In this master thesis a novel way of trapping nanosized particles were tested. The technology used was based on acoustic trapping with seed particles. In difference to earlier devices the seed particles were held in place by a physical barrier that worked like a filter, stopping the bigger seed particles while allowing the nanosized particles to flow through, a setup that allowed for significantly

Grass pollen allergens, including Phl p 5 from Phleum pratense, are major triggers of seasonal allergic rhinitis, primarily mediated by IgE antibodies. This study investigates the genetic basis and functional characteristics of IgG1 antibodies targeting Phl p 5, possibly derived from type 2 memory B cells predisposed to IgE switching. Using site-directed mutagenesis, we analyzed variants of a high

Simulating the behavior of charged particles in linear accelerators requires calculating the effects of electromagnetic fields on the particles. One source of these fields is the particles themselves, through the so-called space charge self-field. To compute this field, the Poisson equation must be solved using the charge distribution of the particle bunch. In most cases, this cannot be done analy

This bachelor course, Architecture in the Contemporary, focuses on exploring the spatial and communicative aspects of the 'Naturrum' through surface modeling experiments. Throughout the course, various approaches have been used to engage with the core themes of the subject. Utilizing Rhino and Grasshopper, along with a narrative-driven design process, we have been introduced to the concept

The terrestrial ecosystem stores up to 2400Gt of carbon in the upper 1m of the soil profile. However, this carbon storage is not stable and is vulnerable to loss. Agricultural soils with continuous heavy management drive a release of this soil carbon to the atmosphere. Recently, the implementation of perennial crops has been suggested as a method to facilitate a greater carbon sequestration. Howev

Den som har använt GPS under en längre tid med en äldre telefon eller en smart klocka har antagligen märkt att batteriet snabbt tar slut. GPS har dessutom sämre precision om du är inomhus eller i en större stad med höga byggnader. I detta examensarbete så undersöks en alternativ teknik för utomhuspositionering som är mer batterivänlig än GPS. GPS har länge dominerat inom positionering på grund avFor many years, outdoor localization has been dominated by Global Positioning System (GPS) and other GNSS-based methods. While GPS provides global coverage and usually high accuracy, it has its limitations. GPS has lower accuracy in areas with many obstructions, such as buildings or trees, and is power consuming compared to other localization methods. Therefore, GPS may not be the best localizatio

Family oriented design has long been championed by sprawling suburbs and new town developments. Denser urban places have in most cases not been designed to attract or keep families as inhabitants, instead focusing on other qualities and user-groups. This has consequently led to a family flight from urban settings to monofunctional family oriented suburbs, in many chases exhilarating car-depencany

Omvandling av energi har spelat en stor roll i samhällets utveckling: från eldens upptäckt via vatten- och väderkvarnar till kol och olja under industriella revolutionen. Gemensamt för alla dessa energiformer är att de antingen går att lagra, som i bränslenas fall, eller att variationer i vatten- eller väderförhållanden inte har någon stor påverkan på resultatet. I elnätet, däremot, måste det rådaThe subject of energy storage is of increasingly more research interest with a larger share of unpredictable and cheap renewable energy entering the grid. Behind only batteries and pumped hydro in technological maturity, compressed air energy storage stands as a possibility in balancing the grid of the future, with its main benefits being highly efficient utilisation of fuel energy and high flexib

I södra Sverige kan du hitta byn Immeln, som ligger vid södra änden av sjön Immeln. Det är en liten by med cirka 300 invånare. Antalet invånare ökar dramatiskt under sommarmånaderna på grund av den vackra naturen och utomhusaktiviteterna som miljön erbjuder. Detta examensarbete utforskar en industribyggnad och dess tomt som tar upp en stor del av den östra strandkanten av denna by. Genom att utforIn the southern part of Sweden you can find the small village called Immeln, located at the south end of lake Immeln. It’s a small village with around 300 residents, which increases dramatically during the summer months because of its beautiful nature and outdoor activities. This thesis project explores an industrial building and its plot that is taking up a large part of the eastern shoreline of

This study investigates whether a pulley system enrichment can improve the hunting behaviors of European wildcats (Felis silvestris silvestris) in captivity. It was carried out in support of the conservation efforts to reintroduce and preserve the endangered Scottish wildcat population. The research was conducted on four European wildcats at Nordens Ark zoo in Sweden. The enrichment device was des

What makes a beetle attractive? My project looks at how green tortoise beetles (Cassida viridis) choose partners, and which physical traits have a higher success in obtaining a mate. I did this by tracking individuals in three wild populations of Skåne, Sweden, and taking photographs of mating beetles. To document differences between the sexes and populations, see how many partners a beetle has,

Det finns få behandlingar som leder till betydande symptomlindring för patienter som lider av Somatic Symptom Disorder (SSD), men den internetbaserade psykodynamiska terapiformen Emotional Awareness and Expression Therapy (I-EAET), har visat lovande resultat. Dock finns det inte mycket kunskap om patienters erfarenheter av internetbaserade behandlingar på lång sikt. I denna studie intervjuades tolFew treatments lead to significant symptom reduction for patients diagnosed with Somatic Symptom Disorder (SSD), but the internet-based psychodynamic Emotional Awareness and Expression Therapy (I-EAET) has shown promising results. However, little is known about the patients’ long-term experiences of internet-based treatments. In this study, twelve participants who had undergone I-EAET were intervi
