  1. 1. Acoustic Characterization of Catalyst

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Surachit Dokson; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Nationalekonomiska institutionen

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

    Abstract : 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. READ MORE

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

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Ida Vartia; [2022-09-28]
    Keywords : ;

    Abstract : 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.

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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Martin Asuquo; [2022]
    Keywords : ;

    Abstract : 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.

  6. 5. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

    University essay from Lunds universitet/Kemiska institutionen

    Author : Andras Szanthoffer; [2022]
    Keywords : Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

    Abstract : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. READ MORE
