From trash to treasure – detta är återbruk Vi lever idag i ett samhälle där ”slit och släng” är vanligt för bland annat kläder, möbler och leksaker. När något går sönder eller en nyare modell finns ute på marknaden slängs många föremål som hade kunnat användas (återbrukas). Att slänga föremål som fungerar eller hade kunnat lagas, skadar miljön. Det finns en tro om att återbruk av föremål inte är fToday we wear and tear objects and materials, in line with the linear economy. By instead reusing, the need for new production decreases, and so the extraction of raw materials, greenhouse gas emissions and generation of waste. By increasing the reuse rate, we can strive towards a circular economy and climb EUs waste hierarchy. The aim of this master’s dissertation was to study different business

Shared Reading is a reading promotion concept that originated in the United Kingdom and has, over the past three years, begun to engage various actors in Sweden including the Swedish hospital library. In the use of the method, health-promoting effects have also been identified, which is why Shared Reading has interested research in so-called medical humanities in a Swedish as well as an internatio

Light Detection and Ranging (LiDAR) is a technique that can change the way automated systems interact with their environments. The most common LiDAR systems used in industry today are based on the concept of Time-of-Flight (ToF) and utilizes pulsed lasers. Coherent LiDAR, such as Frequency-Modulated Continuous- Wave (FMCW) LiDAR, which operates with a chirped continuous-wave laser, offers advantag

The principle of fiscal neutrality is the essence of the EU VAT system. It aims at relieving taxable persons of the burden of VAT through the deduction mechanism provided for by the VAT Directive. In its another aspect, the principle is a means of reflecting the equal treatment of taxable persons. The equal treatment of taxable persons ensures that taxable persons in a comparable situation are not

Den sydatlantiska anomalin (SAA) är området med svagt magnetfält som sträcker sig från Afrikas västra kust in över Brasilien. Under det senaste 160 åren har området som omfattar den SAA växt i storlek samtidigt som området långsamt har rört sig västerut. Då SAA sammanfaller med en generell avsänkning i magnetfältets intensitet har det spekulerats i att den SAA kan vara inledningen på ett större skThe South Atlantic Anomaly (SAA) is the area with a weak magnetic field that extends from the western coast of Africa to inland Brazil. During the last 160 years, the area that covers the SAA has had an increase in size with a simultaneous, slow westward movement. The development of the SAA coincides with a generally decreasing intensity of the magnetic field. This has led to speculations that the

Dagens samhälle präglas av en omfattande arbetslöshet. Arbetslöshet är stigmatiserat ur allmänhetens perspektiv. Vissa grupper av personer drabbas hårdare av denna stigmatisering då de redan bär på ett annat stigma. En sådan grupp är ex-kriminella personer med en missbruksbakgrund, så kallade ex-missbrukare, vilka utsätts för fördomar och exkludering i arbetssökande sammanhang. Denna uppsats under

Retailbranschen har under de senaste åren genomgått en radikal förändring där allt större fokus har flyttats mot e-handeln. E-handelskonsumenter upplever ofta en osäkerhet och en känsla av risktagande på grund av orealistisk produktexponering, inkorrekt produktinformation, osäkerhet kring betalning, datainsamling samt produkternas kvalitet och material. Det är därför av yttersta vikt att e-handels
