  1. 21. Pearls as bycatch mitigation strategy for Harbour porpoise (Phoecena phoecena)

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Sara Gustafsson; [2020]
    Keywords : harbour porpoise; bycatch mitigation; acoustic reflector; pearl; gillnet; F-POD; click rate; click behaviour; inter-click-interval; terminal buzz; diel phase; GAM;

    Abstract : One of the major threats to harbour porpoise population sustainability is thought to be the high incidence of bycatch specifically in gillnets. This study aims to examine the use of acrylic class pearls developed in an earlier study as acoustic reflectors on gillnets in an effort to increase their visibility to echolocating harbour porpoises in the lumpsucker fishery in Kattegatt.

  3. 22. The European Environment Agency in International Relations - From a Passive Respondent to an Active Participant and Influencer in International Relations

    University essay from Malmö universitet/Fakulteten för kultur och samhälle (KS)

    Author : Kyösti Mäkelä; [2020]
    Keywords : European Environment Agency; EEA; European Commission; Environmental Policymaking; European Union; Directorate-Generals;

    Abstract : Unlike environmental non-governmental organisations and other knowledge producers, the European Environment Agency (EEA) seems to attract seemingly little academic interests among scholars of international relations. With this in mind, this thesis seeks to discuss how knowledge institutions such as the EEA may be seen as active participants in IR, while simultaneously seeking to extend academic discussion considering the EEA itself.

  4. 23. Method development for the analysis of PFAS and neutral precursors in active and passive air samplers

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Pascal Camoiras González; [2019]
    Keywords : ;

    Abstract : Poly- and perfluoroalkyl substances (PFAS) are a chemical class of global concern because of their persistence, toxicity and widespread presence in the environment. This work aimed to develop a robust and reliable method to analyse perfluorohexane sulfonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), as well as the neutral volatile PFOS precursors, namely perfluorooctane sulfonamides and perfluorooctane sulfonamidoethanols (FOSAs/FOSEs).

  5. 24. A Linear, Wide-band, Low-Power Receiver for Narrowband- Internet of Things (NB-IoT)

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Rohan Raghunath; Ghanashyam Ravindranath Prabhu; [2018]
    Keywords : NB-IoT; FTNC; Harmonic rejection; N-path filtering; RX Front End; Low power; Wide-band; Passive mixer; Current mode; Technology and Engineering;

    Abstract : Advancement of technology with the aid of new application, wireless communication has grown rapidly in the past two decades. Recently, in the wireless communication industry, Narrowband- Internet of Things (NB-IoT) is being discussed by everyone, as the most important emerging technology of the day. READ MORE

  6. 25. Analytical and Numerical Study of a Passive Self-Tuning Resonator

    University essay from Lunds universitet/Mekanik

    Author : Majeed al Tmizi; [2018]
    Keywords : Energy harvesting; mechanical vibrations; passive self-tuning; beam resonators; string resonators; sliding proof-mass; MEMS; actuators; Technology and Engineering;

    Abstract : Energy harvesting, from ambient vibrations, can be a very effective method for solving the problem with powering electronics were the need for constant power or regular battery replacements is a trouble or an inconvenience. But, since all energy harvesters, using mechanical vibrations, need to operate in resonance in order to generate maximal electrical output, and ambient vibrations usually do not have a constant vibration frequency, this results in the need for efficient self-tuning systems.
