Fintrådiga alger – husligt eller kusligt för djuren? Som många säkert vet har Östersjön varit (och är!) utsatt för många påtryckningar från oss människor. Näringsämnen från åkermark, utlopp, bekämpningsmedel har fått åka rakt ut i havet vilket har lett till övergödningen av Östersjön. Utöver det har det bedrivits ett överfiske under en lång tid som bland annat har minskat antalet stora rovfiskar.Macroalgae are important habitats which can be found almost all over the world. An alteration has been observed from perennial species to annual filamentous algae during the last decades. This change has affected the abundance, diversity and composition of the invertebrate fauna living in these habitats. This study observes how the increasing amounts of epiphytic, filamentous algae growing on the

I Sverige avlider över tusen personer varje år till följd av en fallskada och cirka 70 000 personer skadas såpass allvarligt att de behöver vård. Fallolyckor kostar Sverige 11.1 miljarder kronor per år och är en av de största utmaningarna för sjukvården och äldreomsorgen idag. Då risken att råka ut för en fallskada ökar med ålder samt att en stor del av befolkningen i Sverige beräknas nå pensionsåMore than a thousand people die each year in Sweden due to fall injuries and approximately 70,000 people injures themselves so seriously that they need care. Falling accidents cost Sweden 11.1 billion SEK a year and is one of the biggest challenges for healthcare and elderly care today. Since the risk of fall injuries increase with age and a large part of the population in Sweden is expected to re

Abstract Purpose: The purpose of this paper is to investigate the extent to which a strongly identity driven (brand oriented) organization in the not-for-profit sector can meet the expectations of the market’s wants and needs and still stay true to its identity. Methodology: Literature review, case studies Findings: The paper finds that brand oriented organizations that are fully aligned with

Purpose: The purpose of this paper is to investigate the influence of pop-up stores on brand equity of online retailers from the consumer's point of view. The theoretical approach aims at highlighting the most crucial parameters when measuring brand equity regarding the use of pop-up stores. This will be further analysed in the empirical part. Furthermore, the objective is to develop a theoret

In forest biomass estimations, three dimensional (3D) canopy structure data derived from images captured by unmanned aerial vehicles (UAVs), also known as drones, has shown potential due to the flexibility and cost efficiency of the method. However, little research has been done for its applicability in bioenergy forest. In this study, a method was developed with the purpose of remotely estimating

Surface roughness is one of the main challenges for the growing industry of additive manufacturing. Not only are surfaces rougher than on components produced by conventional means, but there is also a great variation within a single component as well. In this thesis, we have studied the surface roughness of AM components using focused variant microscope and X-ray computer tomography. This is used

Despite aiming for more civic engagement in tourism industry, The Indonesian Tourism Board effort to transform more citizen to become government-version of travel bloggers was faced by a protest since some travel bloggers didn’t feel common values exist. Therefore, this thesis identifies travel blogger’s intrinsic and extrinsic motivations by recognizing the transformation process that develops re

Akustisk infångning kan bli ett värdefullt verktyg i medicinsk forskning Från ett enda blod- eller urinprov kan läkare få massvis med information om en patient - information som ger ledtrådar om allt från det allmänna hälsotillståndet till eventuell förekomst av infektioner eller inflammationer, eller huruvida patienten lider av en viss sjukdom. Detta beror på att provet innehåller massor av så kaMicrofluidic systems allow for fast and precise manipulation of small volume samples in a highly controlled environment. In such a system, acoustic trapping is a powerful tool, enabling non-contact isolation of cells and microvesicles from complex media. In this technique, an ultrasonic standing wave is introduced in the microchannel. The standing wave exerts size-dependent acoustic forces on part

The purpose of this thesis has been to shed light upon, and create an understanding of, social forces that can hamper or enable the establishment and future development of the needle exchange program in Helsingborg. More specifically, the thesis has investigated how different discourses of drug abuse and the external organizational environment, in terms of imitation and legitimization, have influe

Purpose: The purpose of this paper is to see what luxury brands gain from a limited-edition collaboration in terms of segment, positioning and target group and based on the identity prism, see what characteristics that are transferred from and to the brands in the collaboration. Design/methodology/approach: First a literature review is presented with relevant theories for the purpose of the paper

Purpose: The purpose of this paper is to investigate how brand activism in advertisements (specifically femvertising in this case) affects male consumers’ attitudes towards the brand behind the advertisement Methodology: The study is of qualitative nature, using primary and secondary data. Secondary data were gathered from academic journals forming the foundation for the theoretical framework. Pr

Numerous broad insights have emerged in the last decades concerning the invasive non-indigenous round goby (Neogobius melanostomus) and its expanding presence in the Baltic Sea. The waters surrounding the Danish isles are the final frontiers separating the Baltic Sea from the North Sea, and although they offer highly favourable habitats, the biotic resistance in Öresund by native competitors might

Sweden today is suffering from a housing shortage. Not least among young adults, students in particular. One reason to why the supply of housing is insufficient and unable to meet the demands most likely has to do with the slow construction rate that occured between the years of 2008 and 2012. The slow construction rate combined with an increased demand in proportion to the growing population has

Bumble bee compound eye sizes in different climates Bumble bees are important pollinators with over 250 species spread over the world. One could even argue that they are the cornerstones of life as we know it, considering their immense task of pollinating almost everything we eat, as well as everything that what we eat eats. But how does the bumblebee do all this, in all these vastly different p

Suitability of Dynamic Latches for Sub-VT Operation Sina Borhani Soc11sbo@student.lu.se Department of Electrical and Information Technology Lund University In the past the major concerns of VLSI designers were the performance and area of electronic devices but right now because of technology scaling in CMOS and also with the substantially growth in portable computing gadgets like smart phones

Understanding neoliberalism as a many-headed heterogenous global tendency, this thesis aims to investigate, analyse and gather lessons in the global resistance against it. It is particularly focused on Pirin National Park in Bulgaria, where government changes to its management and development have sparked year-long protests. I ask how neoliberalism manifests itself in Bulgarian environmentalism an

The purpose of this work was to use spatial-temporal analysis for the prevention and mitigation of disease spread. A prototype application was specifically designed to detect territories with a high incidence of cases and a second was used to validate the results. The first algorithm tried to find clustered cases territories and compare them to the smooth average of the previous two years of data

Can Machine Learning Provide more Insights in Cardiovascular Disease? Cardiovascular (CV) disease is the main cause of morbidity and mortality all over the world and the number of people suffering from CV complications is growing as the population is getting older. Despite of knowing several risk factors such as age, hypertension, body mass index (BMI) and genetics associated to CV complication,

Sweden has the reputation of being one of the most sustainable and innovative countries in the world, when it comes to environment-related technology. However, the ecological footprint rates indicate, that Swedes are currently living lifestyles that would require the equivalent of four Earth-like planets to sustain. Most carbon foot-print emissions are closely connected to household activities, wi
