  1. 1. Undersökning av ljudemission för conveyorsystem enligt standard

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Evin Haddad; Carl Eriksson; [2023]
    Nyckelord :Arbetsmiljö; decibel; ljudemission; standard och testutförande;

    Sammanfattning : I strävan efter en effektiviserad och optimerad produktion har conveyorsystem blivit en betydande del av många industrier. Med ett stort utbud av tillgängliga conveyorsystem uppstår behovet av standarder för dessa system. LÄS MER

  3. 2. Acoustic Characterization of Catalyst

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Surachit Dokson; [2023]
    Nyckelord :;

    Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER

  4. 3. Simulating sustainable futures - Investigating the implications of CO2 emission caps on economic growth in the OECD

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Anja Sophia Theopold; Ulrika Ericson; [2023]
    Nyckelord :Economic growth; Climate change; Absolute caps on emissions; Technological change; OECD; Business and Economics;

    Sammanfattning : The matters of economic growth and climate change are both widely subjected to discussions and policymakers are under immense pressure to make decisions that enhance economic growth and stop climate change. Policies that ensure economic growth have traditionally had a negative impact on climate change and vice versa. LÄS MER

  5. 4. INVESTIGATING THE TOXIC AND ACIDIFYING EFFECT OF SCRUBBER EFFLUENT ON STRONGYLOCENTROTUS DROEBACHIENSIS LARVAE

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Ida Vartia; [2022-09-28]
    Nyckelord :;

    Sammanfattning : To meet the new environmental requirements of reduced sulfur emissions from ships, many shipowners have installed an open-loop scrubber to clean the exhaust. In this scrubbing process, seawater is pumped from the ocean and combined with the emission gas, creating an acidic and toxic effluent that is directly discharged into the ocean, potentially damaging the marine environment.

  7. 5. Tribology of Polymer Composite with Low Load Application for Automotive Industries

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Asuquo; [2022]
    Nyckelord :;

    Sammanfattning : In recent times, there has been an increased interest in replacing conventional metals and synthetic fiber composites in various automobile parts with natural fiber polymer composites. These natural fiber composites offer benefits over conventional materials in terms of reduction in weight, lower cost, comparable high specific properties such as specific stiffness and strength, low abrasion property, and availability of these materials.
