  1. 1. Biopolymers processed and used as enzyme carriers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Dániel Mészáros; [2023]
    Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. LÄS MER

  3. 2. Metacaspase type II : Biochemical studies of the activation anddegradation process of calcium-independentmetacaspase type II from Arabidopsis thaliana

    Master-uppsats, Uppsala universitet/Nationellt resurscentrum för biologi och bioteknik

    Författare :Anna Vikhagen; [2023]
    Nyckelord :;

    Sammanfattning : Proteases are found in all living kingdoms and are absolute essential for a functional cell to beable to break down peptide bonds. Metacaspases are proteases with the ability to cleave afterarginine and lysine residues. LÄS MER

  4. 3. A new generation ofsmart food packaging : A combination of releasing anti-microbial and generation carbon dioxide inmeat packaging

    Master-uppsats, Karlstads universitet

    Författare :samar salahieh; [2023]
    Nyckelord :adsorption isotherms; desorption kinetics; benzoic acid; thymol; modified calcium carbonate; silica gel; carbon dioxide; food pad.; adsorptionsisotermer; desorptionskinetiken; bensoesyra; tymol; modifierat kalciumkarbonat; kisel gel; koldioxid; food pad.;

    Sammanfattning : Abstract Food sustainability depends significantly on packaging since it helps maintainfood safe and fresh throughout its shelf life, resulting in the least amount ofwaste and the least negative environmental impact. The main objective of thisstudy is to determine the adsorbed and released amount of antimicrobial agents(benzoic acid and thymol) on modified calcium carbonate (MCC) by investigating adsorption isotherm at 25°C and desorption kinetics at both 22°C and5°C of anti-microbial to identify potential solutions to enhance the long-termsustainability of fresh products such as meat.

  5. 4. Predicting and classifying atrial fibrillation from ECG recordings using machine learning

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Carl Bogstedt; [2023]
    Nyckelord :Bioinformatics; Machine Learning; Electrocardiogram; Classification; Rough Sets; XGBoost; Atrial Fibrillation;

    Sammanfattning : Atrial fibrillation is one of the most common types of heart arrhythmias, which can cause irregular, weak and fast atrial contractions up to 600 beats per minute. Atrial fibrillation has increased prevalence with age and is associated with increased risks of ischemia, as blood clots can form due to the weak contractions. LÄS MER

  7. 5. Valpars näringsbehov - vad blir konsekvenserna av felaktig utfodring

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Kristina Thune; [2022]
    Nyckelord :Feeding; growth; nutritional requirements; nutrition; pediatric nutrition; improper feeding; skeletal and joint problems;

    Sammanfattning : The nutrient requirement for puppies is affected by the age and size of the dog. The nutritional requirements for growing individuals are higher than for adult dogs. They have a higher requirement of energy, protein, calcium, and phosphorous to be able to grow and develop. LÄS MER
