  1. 1. An Infrared Stellar Thermometer: Exploiting IGRINS Spectra

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Emelie Sandved; [2022]
    Keywords : Effective temperature; K-giants; surface gravity; oxygen abundance; carbon abundance; CO lines; OH lines; line sensitivities; Physics and Astronomy;

    Abstract : Using the infrared (IR) spectral range when measuring stellar spectra is beneficial compared to using the optical range mainly when observing distant stars through the dust dense interstellar regions in the Galactic mid-plane. Methods to determine stellar parameters from IR spectra are, however, not fully developed yet because technological difficulties in creating reliable IR detectors have slowed the advance of such methods.

  3. 2. Pilotstudie av hästars termiska komfort med olika tjocka täcken : mätning av temperatur och relativ luftfuktighet under täcket

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Matilda Hagelsten; [2022]
    Keywords : Nedre kritisk temperatur; täcke; termisk komfort;

    Abstract : Det är vanligt att både klippta och oklippta hästar täcks stor del av året för att öka hästens isolering och vissa hästar täcks redan vid 10C. Problemet som uppstår är att hästägare inte har tillräckligt med kunskap och att det finns begränsat med vetenskaplig information om hur temperaturen under täcket påverkas av tjockleken på täcket.

  4. 3. An Infrared Stellar Thermometer

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Ieva Puspure; [2021]
    Keywords : Infrared Spectroscopy; Infrared; Red giants; Stellar Temperature; Spectroscopy; Physics and Astronomy;

    Abstract : Infrared (IR) spectroscopy has many advantages over optical, one of which is allowing us to see through intergalactic dust, letting us probe deeper into space and dust-dense regions such as galactic centers. However the investigating the IR spectral range is a relatively new field, owing to recent developments in detector technology, and stellar parameter determination in IR is not well researched.

  5. 4. In-vivo assessment of unwanted tissue heating during near infrared laser light emission

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Martin Molin; [2020]
    Keywords : tissue heating; laser heating; NIR window; biophotonics; spectroscopy; Medicine and Health Sciences;

    Abstract : In this work, potential adverse tissue heating in conjunction with near infrared (NIR) laser spectroscopy was studied. The tissue heating from laser light within the NIR optical window is currently a relatively unexplored field. READ MORE

  6. 5. Changes in dairy cows’ temperature

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : jessica isaksson; [2017]
    Keywords : dairy cows; core body temperature; rectal temperature; skin temperature; infrared camera;

    Abstract : Lactating cows have a higher heat production due to the milk synthesis compared to dry cows. In the regulation and general advice regarding animal husbandry (SJVFS 2010:15) it is stated that animals should be kept in thermal comfort. READ MORE
