1. 1. The implications of heavy fuel oil ban in arctic waters for sustainable arctic shipping

   University essay from Göteborgs universitet/Institutionen för marina vetenskaper

   Author : Kaung Thu; [2023-01-23]
   Keywords : Arctic region; heavy fuel oil; shipping; Sustainable;

   Abstract : The increased temperature in the polar regions is one of the significant impacts of global warming and consequential climate change. In the Arctic, regional warming leads to the accelerated loss of sea ice caps, which has opened up new international shipping routes. READ MORE

3. 2. Critical elements scavenged by secondary gypsum and HFO : Determined by sequential extraction combined with mineralogical studies

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Emma Flodin; [2022]
   Keywords : Geochemistry; gypsum; HFO; adsorption; scavenged; critical elements; beryllium; Yxsjöberg; mine waste; Sequential extraction; XRD; SEM-EDS;

   Abstract : The demand for metals is great for the purpose of developing green technologies, and EU has listed 30 metals and minerals that are of critical importance for the maintenance and evolving of today’s society, so called critical materials. However, mining of raw materials generates mine waste which can have adverse effect on human health, ecosystems, and surrounding areas. READ MORE

4. 3. Development and validation of sample clean-up using solid phase extraction prior oil spill fingerprinting

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Cheryl Loorents; [2022]
   Keywords : Oil spill; chemical fingerprint; solid phase extraction SPE ; development; validation.;

   Abstract : In a forensic investigation involving oil, a comparative analysis named oil spill fingerprinting between a source and an oil spill is normally performed. It is based on detecting a certain selection of biomarkers with gas chromatography (GC) coupled to mass spectrometry (MS) which are later divided into diagnostic ratios (DRs). READ MORE

5. 4. Optimization of solid-phase extraction (SPE) as sample preparation for oil samples in forensic investigations.

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Aamanda Chang; [2021]
   Keywords : Solid-phase extraction SPE ; heavy fuel oil HFO ; fingerprint; polycyclic aromatic hydrocarbons PAHs ; biomarkers.;

   Abstract : Oil spills, especially in water have happened throughout the years. The consequences from this kind of incident have always been a threat to marine life and take a lot of money and time to clean up. READ MORE

6. 5. HIGH-FREQUENCY OSCILLATIONS IN A MOUSE MODEL OF PARKINSON’S DISEASE

   University essay from Umeå universitet/Institutionen för psykologi

   Author : Love Zachrisson; [2020]
   Keywords : 6-OHDA; Parkinson s Disease; Basal Ganglia; LID; Gamma oscillation; 80Hz; HFO; Multichannel electrode array; Parkinsons sjukdom; 6-OHDA; LID; HFO; Gamma oscillering; 80Hz; Basala Ganglierna; Elektrodimplantat;

   Abstract : Dopamine replacement therapy is the main method of treating Parkinson’s Disease (PD), however over time this treatment causes increasingly abnormal, involuntary movements. This symptom, known as Levodopa-Induced-Dyskinesia (LID) is associated with aberrant, high frequency oscillations (HFOs) in the motor cortex and basal ganglia, as demonstrated with implanted electrodes in human Parkinson’s patients as well as in a rat model of Parkinson’s Disease.
