1. 1. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ivana Pia Saric Söderholm; Erik Readwin; [2023]
   Keywords : Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

   Abstract : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

4. 3. Total proteolysis in bovine raw bulk milk of Northern Sweden

   University essay from SLU/Department of Molecular Sciences

   Author : Elina Toss Ekmyr; [2020]
   Keywords : total proteolysis; plasmin; SDS PAGE; total bacteria count; somatic cell counts;

   Abstract : Proteases are enzymes that catalyze protein breakdown. The major indigenous protease is plasmin, that together with proteases originating from somatic cells and bacteria, accounts for most of the proteolytic activity in bovine milk. In many dairy products, the key characteristics depends on the concentration and composition of the milk proteins. READ MORE

   Abstract : This paper investigates correlation between energy consumption 24 hours ahead and features used for predicting energy consumption. The features originate from three categories: weather, time and previous energy. The correlations are calculated using Pearson correlation and mutual information. READ MORE

6. 5. Evaluating a Novel, Scalable Natural Language Processing Heuristic for Determining Semantic Relatedness

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Mattias Bergström; Per Fahlander; [2019]
   Keywords : ;

   Abstract :  Distributional semantics is a recent research field aiming to quantify how close one text is to another in terms of contextual meaning. In this study we propose and evaluate a novel distributional semantics model on how much agreement its predictions can yield with a set of 12,227 human opinions. READ MORE
