  1. 1. Models for estimating radiation dose and LAR from radioactive fallout: extended dose algorithms for the computational tool LARCalc

    University essay from

    Author : Jonathan Sundström; [2022-09-09]
    Keywords : Medical physics; Nuclear power plant; Radiation dose; Effective dose; Lifetime attributable risk; LAR; Fallout; Inhalation; Strontium-90; Iodine-131; Cloudshine;

    Abstract : Today, emergency preparedness is needed against both nuclear reactor accidents and nuclear weapons fallout. Both scenarios can lead to exposure of ionizing radiation. Upon exposure, radionuclides will incur a radiation dose both internally and externally. READ MORE

  3. 2. Scenario Dose Calculation for Robust Optimization in Proton Therapy Treatment Planning

    University essay from Lunds universitet/Matematik LTH

    Author : Johan Sundström; [2021]
    Keywords : cancer; radiation therapy; proton therapy; treatment planning; robust optimization; dose calculation algorithms; scenarios; patient setup; range error; organ motion; pencil beam scanning; computational efficiency; range-corrected dose-mapping; Mathematics and Statistics;

    Abstract : Robust optimization plays a vital role in proton therapy treatment planning. A monoenergetic beam of protons has a finite range and delivers most of its dose at some specific depth in the patient. This allows the design of treatments that mainly damage the tumor and not any surrounding tissue. READ MORE

  4. 3. Skogliga studenters syn på yrkesrollen virkesköpare – en jämförelse mellan kvinnor och män

    University essay from SLU/School for Forest Management

    Author : Moa Hermansson; Anna Sundström; [2021]
    Keywords : jämställdhet; yrkesstatus; könstillhörighet;

    Abstract : Skogsbranschen i Sverige har under lång tid dominerats av män. Detta på grund av att ett skogligt yrke historiskt sett har varit fysiskt krävande och därmed ansetts passa bäst för män. I dag har andelen kvinnor som är yrkesverksamma inom skog eller som läser en skoglig utbildning ökat. READ MORE

  5. 4. Privata skogsägares preferenser och betalningsvilja vid val av maskinstorlek i gallring

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Linnea Sundström; [2019]
    Keywords : gallring; maskinval; skogsägare; kvantitativ; studie;

    Abstract : Hälften av Sveriges skogsmark ägs av privata skogsägare och resterande halvan fördelas mellan staten, aktiebolag och övriga privata ägare. När dessa skogsägare brukar sin skog är gallring en vanlig skötselåtgärd för att under en omloppstid öka tillväxten i ett givet bestånd. READ MORE

  6. 5. Dynamic Simulation of a One-Cylinder Engine Test Rig

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Per Sundström; [2017]
    Keywords : ;

    Abstract : An engine test rig at AVL was redesigned with new components after a failure. The new system consists of a torsional vibration damper, a cardan axle, a torque flange, and an adapter unit, together with a new dynamometer. To ensure another failure would not occur a study of the new system was conducted. READ MORE
