  1. 6. On the superconducting critical temperature in Eliashberg theory

    University essay from KTH/Fysik

    Author : Max Oliveberg; [2021]
    Keywords : Eliashberg; Superconductivity; Mathematical Physics; Eliashberg; Supraledning; Matematisk Fysik;

    Abstract : This thesis presents a brief synopsis of the derivations of the BCS and Eliashberg equations. An analytic formula for the critical temperature $T_c$ in Eliashberg theory is derived, which contains a sum of iterative integral corrections. READ MORE

  3. 7. Scheme Theory & Weak Mordell-Weil for Elliptic Curves Over Number Fields

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Carl-Fredrik Lidgren; [2021]
    Keywords : algebraic geometry; schemes; scheme theory; elliptic curves; Mordell-Weil; weak Mordell-Weil; algebraic number theory; arithmetic geometry; number theory; geometry; Mathematics and Statistics;

    Abstract : We provide an introduction to scheme-theoretic algebraic geometry, which studies spaces that are in essence locally solutions to systems of polynomial equations, and prove the weak Mordell-Weil theorem. The weak Mordell-Weil theorem states that for an elliptic curve $E$ over a number field $K$, the quotient $E(K)/mE(K)$ is finite for all $m\geq 2$. READ MORE

  4. 8. Long-term effects of a synbiotic intervention in ADHD-patients : 18-month follow-up

    University essay from Linnéuniversitetet/Institutionen för psykologi (PSY)

    Author : Jaqueline Fricke Palmell; [2020]
    Keywords : Synbiotic intervention; probiotics; prebiotics; microbiota; ADHD; autism; emotion regulation; functional impairment; lactic acid bacteria; inflammation; anti-inflammatory; Synbiotika; probiotika; prebiotika; mikrobiota; intervention; ADHD; autism; emotionsreglering; funktionsnedsättning; mjölksyrabakterier; inflammation; anti-inflammatorisk;

    Abstract : A link between the gut and the brain has been proposed to influence psychiatric disorders. Probiotics have been suggested to modify the gut microbiota and thereby improve autism symptoms in children. Attention deficit hyperactivity disorder (ADHD) has high comorbidity with other neuropsychiatric diagnoses, including autism. READ MORE

  5. 9. Movement initiation and execution in 6 - 8 year old children born preterm: effects of gestational age and physical activity

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Klara Stjernholm; Lisa Wennergren Gros; [2020]
    Keywords : Prematurity; movement planning; kinematics; physical activity; cognitive abilities; Prematuritet; rörelseplanering; kinematik; fysisk aktivitet; kognitivförmåga;

    Abstract : The purpose of this study was to explore differences in movement initiation and execution, and their associations with amount of physical activity (PA) and cognitive abilities, in 6 to 8 year old children born PT compared to peers born at term. The sample consisted of in total 78 children divided in subgroups, 16 born very preterm (VPT), 24 born moderate preterm (MPT) and 38 age matched controls born at term (FT) with no diagnosed cognitive or motor impairments.

  6. 10. Estimating Risks of Pharmaceutical NSAID Mixtures in Surface Waters through Risk Cups : – Implications for Sustainability

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Per Mandahl; [2020]
    Keywords : Sustainable Development; Ecotoxicology; Risk Cup; Pharmaceuticals; Surface Water; MEC PNEC;

    Abstract : Background: Use of pharmaceuticals can lead to unchanged or metabolite residues in surface water that may result in negative environmental effects. Sweden has adopted the Generational goal defining direction and changes needed to become a sustainable nation, these align with the UN Sustainable Development Goals (SDGs). READ MORE
