  3. 2. 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. Evaluation of liver and fur copper concentrations in dairy cows : in relation to dietary intake of copper and molybdenum

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Ida Hansen; [2023]
    Keywords : copper; copper status; dairy cow; fur; liver; molybdenum; ruminant;

    Abstract : Koppar (Cu) har en avgörande roll i flera viktiga metaboliska funktioner och är en essentiell mineral för idisslare. Kopparbrist kan resultera i ett flertal problem som påverkar djurets hälsa och produktion, men även överutfodring av Cu kan resultera i allvarliga kliniska symptom på grund av ackumulering av Cu i levern.

  5. 4. Dairy cow copper status in molybdenum rich areas : focus on copper excretion in faeces, urine and milk

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Lisa Stensson; [2023]
    Keywords : dairy cow; ruminant; copper; molybdenum; antagonist; excretion;

    Abstract : Koppar (Cu) är ett essentiellt spårämne med flertalet funktioner hos idisslare men både över- och underutfodring kan ha negativa effekter på djurets hälsa och produktion. Utöver det interagerar Cu med andra mineraler i våmmen vilket minskar tillgängligheten av Cu i tunntarmen. READ MORE

  6. 5. Possibilities of Reducing Internal Scrap Rates and Increase Scrap Recyclability of Dilute Copper Alloys from Vertical Upwards Continuous Cast (VUCC) Process

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Minna Olsson; [2023]
    Keywords : metallurgy; copper; alloy; continuous casting; materials chemistry; Technology and Engineering;

    Abstract : Copper and copper alloys are important material systems for the electrification of society. The high workability of the materials makes them appropriate in numerous different applications which require highly conductive properties. READ MORE
