Det här examensarbetet fokuserar på att designa och konstruera en ny typ av instrument för att studera plankton och den miljö de lever i. Arbetet utnyttjar de framsteg som gjorts inom små diod-lasrar och små kamerasensorer tillsammans med innovativ optik för att konstruera ett kompakt och relativt billigt instrument som på avstånd kan upptäcka individuella plankton på flera djup samtidigt och på saThis thesis is oriented around designing the world first inelastic hyperspectral LiDAR(Light Detection and Ranging) system for aquatic use. The system was designed around the task of monitoring zooplankton and environmental indicators in water. Scheimpflug lidar was previously developed for monitoring flying insects, aerosols and gases. Here we extend the concept to inelastic hyperspectral ranging ca

The purpose of the study was to investigate if dynamic way-guidance systems, namely flashing green lights mounted by an exit sign, can be used to increase the usage of lesser known egress routes in department stores. The study consisted of a literature study as well as experiments at Gekås department store in Ullared, Sweden. Two experiments were undertaken, one in the vicinity of the checkout and

With effect of global warming and climate change the electrification of vehicles enables a more sustainable and environmentally friendly alternative to conventional vehicles as it reduces toxic emissions and overall energy consumption. Different extents of electrification is today used. Hybrid and electric vehicles are two examples. Tools to simplify the design of electric vehicles are of value to

Problem: Hållbarhetsredovisning har alltid varit fri från formkrav vilket har inneburit stor flexibilitet för företag både sett till om hållbarhets- rapporter ska upprättas och vilket innehåll dessa ska ha. Då lagreglering blir gällande från och med räkenskapsåret 2017, som gör det tvingande för större företag att hållbarhetsredo- visa, frågar vi oss hur detta lagkrav kan komma att påverka den inf

Klimatförändringar medför ökad risk för översvämningar och kustnära Göteborg är särskilt utsatt. Aktörerna som arbetar med att hantera översvämningsrisker bildar ett socialt nätverk och hur det ser ut kan få stora effekter för riskhantering i samhällsplaneringsprocessen. Via examensarbetet har det nu gjorts försök att kartlägga och analysera effekterna av detta nätverk. Förändringar i klimatet orDue to today’s climate changes, the risk of flooding is increasing, both caused by rising sea levels and as a consequence of heavy rainfall. Urban environments are largely consisting of impermeable surfaces, unable to permeate large amounts of water in the event of a flooding. In the scope of this work, the aim has been to map the social network of actors involved in flood management in Gothenburg

Fruits and leafy vegetables are the major target of pathogenic E.coli outbreaks. Usually soil and other contaminants present in the land provides easy pathway for pathogenic bacteria to enter the plant body. Later upon consumption of such infected food lead to various health problems. To overcome such outbreaks, during our study one of the leafy vegetable spinach was used as a medium to understand

In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. The dynamic range is maximized by using passive topologies for both the a

The thesis provides an overview of the relationship between tax treaties and domestic law and issues that arise if a contracting state uses domestic anti-avoidance rules to prevent the improper use of a tax treaty. Improper use of a tax treaty is an issue addressed in the BEPS Action 6 report. The suggestion is to include a limitation-on-benefits clause in the OECD Model Convention, a principal pu

Humor is a big part of people's everyday life and social interactions, although we don’t consider humor and social work as a natural combination. We have interviewed Swedish social workers and asked them about their perspective on humor and how they use it in their work. We analyzed the material using superiority theory and the dramaturgical perspective to find which functions and norms they r

with the concept of self- determination, how they describe methods they work with and how this can be understood by theories of power. The study was conducted through interviews with eight different personnel from five different group homes, all of them working with individuals with intellectual disabilities. The analysis was based on theories of power – relational power, different ways power can

Hemoglobin är ett viktigt protein. Det återfinns i röda blodkroppar och dess huvudfunktion är att transportera syre genom kroppen. Hemoglobin är komplext till sin struktur, till exempel består proteinet av fyra subenheter. I människor återfinns två varianter: vuxet och fetalt. Förmågan att binda syre, affiniteten, skiljer sig åt mellan dessa. I fetalt hemoglobin är syreaffiniteten högre än i vuxetIn this thesis a preliminary evaluation of the potential of a leghemoglobin (Lb) for the development of a blood substitute in humans, resembling hemoglobin (Hb) in red blood cells, was conducted. Leghemoglobin B (VfLbB), a gene from Vicia faba, was cloned into a pET-DEST42 vector, using the Gateway™ recombination technology. The recombinant vector containing VfLbB was sequenced and confirmed. Then

Bakgrund: Vårdrelaterade infektioner (VRI) utgör ett stort problem, där vanligaste smittvägen är kontaktsmitta via personalens händer. Den viktigaste åtgärden för minskning av vårdrelaterade infektioner är att applicera basala hygienrutiner. Syfte: Syftet med studien var att undersöka om skillnad förelåg i följsamheten av basal handhygien mellan anestesisjuksköterskor och anestesiläkare på kirurgi

This paper consists of a literature study and laboratory experiments of magnesium oxide boards, from Swedish suppliers, that is a part of a larger research project. Lately the boards have become known for the way they absorb moisture which has led to damage on adjacent materials. The boards are inorganic and are marketed as moisture proof. The purpose of the larger research project is to identify

Vi kanske tror att vårt beteende och vår livsstil bara påverkar oss själva. Det stämmer inte. Utsläppen från vår höga levnadsstandard leder till stora problem i hela världen. Världshälsoorganisationen WHO har konstaterat att olika miljöföroreningar dödar tre gånger fler människor i låg- och medelinkomstländer än malaria, AIDS och tuberkolos tillsammans! Dessutom leder våra livsstilsval till växthuThe purpose of this study is to evaluate the effects of behavioral change oriented measures to address climate change problems. Municipalities in Sweden already work with these kinds of measures, but they find it hard to apply for funding since it’s often a requirement to show the emission reductions of each project. The initial part of the study aims to understand how the members of the Climate
