Different actors identified the circular economy (CE) as a solution to tackle global environmental challenges and foster sustainable growth. Transitioning to CE requires new circular business models (CBM), which create, capture, and deliver value, based on the principles of the CE. It is, however, a challenging process for companies see through the wide variety of CBM types and to identify which C

This thesis explores a video phenomenon called “Let’s Play”, that allows people to share their gaming experience with an online audience, for example on YouTube. Let’s Play-videos are a favorite pastime with children. Yet, the knowledge about the information in these videos is sparse. The aim of this study is to contribute with knowledge about how Swedish Let’s Play-producers on YouTube, targeting

En radar använder elektromagnetiska vågor för att kunna skicka och motta signaler. Precis på samma sätt som att våra öron, ögon och tungor är mottagare och vår röst och vårt kroppsspråk är sändare av signaler till världen omkring oss. För både människan och för radarn så behövs det skydd mot omgivningen. Till exempel, har våra ögon ögonlock och vår röst är dold inne i halsen. Utan ögonlock skulle The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. Radomes come in many different shapes, materials and thicknesses, where each of these parameters are decided based on the need for the given radar applicati

När man pratar om industriellt underhållsarbete är mänskliga fel ett viktigt ämne att hantera. Olika typer av mänskliga misstag till följd av farliga tillstånd i vissa speciella parametrar, s.k. Performance Shaping Factors (PSFs) introducerar nya och oförutsägbara risker. Detta examensarbete presenterar en metod som, till skillnad från många metoder som finns tillhands idag, är tänkt som en enkel When discussing industrial maintenance, human error is a topic that easily comes to mind. Slips, lapses and mistakes due to hazardous settings of critical conditions referred to as Performing Shaping Factors (PSFs) introduce unforeseen and unanticipated risks. Unlike several tools to date, the methodology presented in this master thesis is thought to serve as an easy and fast way to identify risks

MIMO (Multiple Transmit and Multiple Receive) antenna techniques are widely used in the most recent wireless communication standards. For example, LTE (Long-Term Evolution), WiMAX (Worldwide Interoperability for Microwave Ac- cess) and IEEE 802.11n have recently been rolled out across the world. In any communication system, the ML (Maximum Likelihood) receiver provides optimal error rate performan

In this work, which is to be used as a supplementary example to the educational literature in Automatic Control, at LTH, I have chosen one reactor, in the group of chemical reactors, for the examination. The chosen reactor is the continuos-flow, autothermic, nonadiabatic stirred-tank reactor. Required cooling of the reaction mixture is achieved by letting the reactor-tank be surrounded by a coolin

Backlash is common in mechanical and hydraulic systems. It severely limits the overall system performance. Many mechanical solutions have been developed to overcome backlash, for example by using spring-loaded split gear assemblies or dual motor systems. These mechanical solutions can satisfactorily handle the backlash problem but they give rise to other problems like decreased accuracy and reduce

In this study, Dissolved Organic Matter (DOM) quality was analysed through its optical properties. Samples from the estuarine waters of the Beagle Channel and oceanic ones of the Burdwood Bank were examined in order to understand how DOM quality was changing. The focus of the study was to determine whether the environmental variables or the microbial community were the main driver in DOM compositi

This thesis work is on the theoretical description of dilute Bose-Einstein condensates (BEC) that are non-uniform, meaning that more than one single-particle state is occupied. This phenomenon is usually called quantum depletion. A common model for the ground state of a dilute and weakly interacting BEC is the mean-field (MF) approximation leading to the Gross-Pitaevskii (GP) equation. However, fo

What does Candida have in common with vaginal microbiota? We share our body with millions of microbes, which share a common space and interact tightly. All the interactions between them are important for keeping a good microenvironment. However, there is always a disruption of what should be otherwise a comfortable place to live. Such changes can be subtle or can affect entire communities of micr

Denna studiens syfte var att undersöka och försöka precisera vad för specifika egenskaper och förmågor hos en psykoterapeut som forskare och teoretiker hitintills har beskrivit vara eftersträvansvärda för att kunna ge en god terapeutisk effekt i psykoterapeutiska behandlingar. Syftet var också att i möjligaste mån skapa en tydlig översiktlig kartläggning och sammanfattning genom att samla ihop mycThe aim of this study was to investigate and try to specify what specific characteristics and abilities of a psychotherapist that researchers and theorists have so far described to be desirable in order to provide a good therapeutic effect in psychotherapeutic treatments. The aim was also to create, as far as possible, a clear overview and summary by collecting as much of material that is currentl

After the major populist events such as Trump and Brexit, the media politicians turned their attention to the socio-economic and political division between big cities and small countryside communities. Rural areas where right-wing populist parties have found a large part of their support have besome “left-behind places", described as forgotten and misunderstood. The question of why these popu

A prerequisite for the effective conservation of species, is the accurate assessment of a species’ distribution and numbers. In order to look into the population sizes of birds, a quantitative atlas project from 1981 included a total count of the inland birds in the Faroe Islands. The aim for my thesis was to look at the population changes from 1981 until 2020, by repeating the 1981 atlas project,

There is a need for harmonisation of stability study designs of monoclonal antibodies. Monoclonal antibodies (mAbs) are widely used in treatments for various diseases. Like all drugs, their quality must be verified through stability studies. The ICH guidelines give general recommendations regarding stability studies of antibodies, and specifications should often be determined on a case-by-case bas

Title: “Language is access to everything” - A qualitative study of SFI-teachers' experience of the transition to digitalized distance education. Authors: Rania Elwan and Fitore Mehmeti Supervisor: Karin Kullberg Assessor: Maria Bergendal Arvidsson The purpose of the study is to investigate from teachers for Swedish for immigrants (SFI) perspective how the transition to digitalized distance ed

The cost of developing and researching novel molecular compounds in the pharmaceutical industry is very high today. If an actor accidentally releases too much information about a novel molecule to the public the molecule becomes prior art, and as an effect, can not be patented. This has resulted in a fragmented space where collaboration across organizations is virtually non-existent. We propose a

Food insecurity is a reality faced by millions of people worldwide. Poor access and availability to food markets, poverty, and uncertain global system futures all exacerbate this issue. In seeking to combat food insecurity for South Carolina residents and improve the viability and resilience of local food markets around Greenville County, South Carolina, this assessment determines optimal potentia

The thesis aims to understand if seed saving practiced by oppressed small-scale farmers and peasants who are affiliated with Navdanya can be seen as a technology of resistance against the dominant agri-food industrial paradigm. Another aim is to find out how political and cultural meanings are attached to seed saving. It also aims to challenge this aforementioned paradigm. The inquiry is exemplifi

The copolymer of N-isopropylacrylamide (NIPAM) and methacryloyl derivative of spirobenzopyran (MSBP) with a molecular weight of 21 000 g/mol and the average molar MSBP content of 1.9% was prepared by free radical polymerization. The copolymer displayed its phase transition in water in the temperature range of 30-50 degreesC. UV irradiation of its aqueous solution caused photoinduced transformation
