  1. 1. Simulations of the Tenuous Upper Atmospheres of Exoplanets

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Lucian Spitzner; [2023]
    Nyckelord :astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

    Sammanfattning : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. LÄS MER

  2. 2. Study of the Non-Thermal Escape ofDeuterium on Mars : Collisions between Suprathermal Oxygen and Deuterium

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Sorcha Mac Manamon; [2022]
    Nyckelord :Atmospheric Escape; Mars; Deuterium; Modelling; Non-thermal Escape; suprathermal oxygen;

    Sammanfattning : Mars’ climate has undergone many massive changes over the course of it’s lifetime. In order toestablish how Mars lost the vast majority of its water, we must be able to understand how Marsis losing its atmosphere today. LÄS MER

  3. 3. Knowledge and Data Driven Approaches for Hydrocarbon Microseepage Characterizations: An Application of Satellite Remote Sensing

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Ali Al Farid; [2020]
    Nyckelord :Geography; Geographical Information Systems; Hydrocarbon Microseepage; PCA; Crosta; Band Ratio; MTMF; Weight of Evidence; SVM; Methane Fluxes; Remote Sensing; Satellite Image Classification; Earth Observation; Mineral Classifications; Machine Learning; Earth and Environmental Sciences;

    Sammanfattning : Methane is a potent greenhouse gas that plays a major role in climate change. Significant uncertainty exists in the estimates of emissions from natural methane sources. This uncertainty in data is one of the primary scientific challenges in climate model. LÄS MER

  4. 4. Study of the effect of vacuum impregnation with different substances on respiration and color of packed baby spinach leaves.

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Ahmad Husain; [2017]
    Nyckelord :modified atmosphere; Spinach; minimal processing; metabolic activity; quality; GABA.; Agriculture and Food Sciences;

    Sammanfattning : In this study, vacuum impregnation (VI) was used to investigate the effect of different solutions: sucrose 21 % (w/v), calcium lactate 1 % (w/v), ascorbic acid 0.1 % (w/v), and GABA 0.075 % (w/v) on atmospheric composition, color, and shelf life of packed baby spinach leaves. VI was performed at two different temperatures: 21 C and 7. LÄS MER
