  1. 1. Chromatin accessibility analysis of spaceflight mouse brains using ArchR

    University essay from KTH/Genteknologi

    Author : Raphaël Mauron; [2023]
    Keywords : Single nuclei ATAC-sequencing; Space Biology; DNA Chromatin accessibility; Neurodegenerative; ArchR; ATAC-sekvensering av enskilda kärnor; rymdbiologi; tillgänglighet av DNA kromatin ; neurodegenerativa sjukdomar; ArchR;

    Abstract : Mänsklig utforskning av månen och Mars innebär stora utmaningar för människans fysiologi och hälsa på grund av de unika miljöfaktorer som följer av långvariga rymduppdrag. Rymdbiologiska experiment har blivit ett viktigt verktyg för att studera effekterna som mikrogravitation och rymdstrålning har på levande organismer, i syfte att förstå och minska dessa utmaningar.

  3. 2. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Alexina Brännlund; [2023]
    Keywords : Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

    Abstract : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

  4. 3. Long-Term Behavioral Effects of Exposure to Imprinting Stimuli in Chicks(Gallus gallus domesticus)

    University essay from Linköpings universitet/Biologi

    Author : Irem Babaoglu; [2023]
    Keywords : Auditory Stimuli; Domestic Chicks; Filial imprinting; Imprinting Procedure; Learning; Novel Object; Social Isolation;

    Abstract : Filial imprinting is a type of early developmental learning in which certain species buildstrong and mostly irreversible connections to objects or individuals. These connections couldbe shaped by the contribution of several stimuli including the fragments of auditory and visual components. READ MORE

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Grisna Isabel Prensa; [2023]
    Keywords : ;

    Abstract : The airborne pathogen Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB) and claims about 1.6 million deaths annually (WHO, 2022). READ MORE

  6. 5. Investigation of Ion Extraction Anomalies at TwinEBIS

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Niek van Woudenberg; [2023]
    Keywords : CERN; ISOLDE; Ion Source; EBIS; REXEBIS; TwinEBIS; Ion losses; Charge Breeding; Ion Extraction; CST Studio Suite; Physics and Astronomy;

    Abstract : The electron beam ion source REXEBIS at CERN-ISOLDE delivers highly-charged ra- dioactive ions for post-acceleration in the HIE-ISOLDE LINAC. Research and develop- ment of components for electron beam ion sources is carried out at the TwinEBIS test stand, currently equipped with a Brillouin electron gun called MEDeGUN. READ MORE
