  1. 1. Energy Landscapes for Early T Cell Development

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Yukun Cheng; [2022]
    Keywords : Physics and Astronomy;

    Abstract : T cell lineage development from an early thymic progenitor involves programmed shutoff of progenitor gene expression, upregulation of T cell specification genes, and proliferation. This biological system has been deeply studied and a gene regulatory network (GRN) that can accurately describe the system has been presented. READ MORE

  3. 2. Investigating Brønsted Acidic Deep Eutectic Solvents for Recycling of Lithium Cobalt Oxide

    University essay from Uppsala universitet/Strukturkemi

    Author : Mattias Lindgren; [2022]
    Keywords : Deep eutectic solvents; Recycling; Lithium-Ion Batteries; Cathode Materials; LCO;

    Abstract : Recently, the production of lithium-ion batteries (LIB) has grown rapidly, highlighting the need for efficient and environmentally friendly recycling of LIB waste. In this work, the usage of so-called deep eutectic solvents (DESs) for the leaching of the LIB cathode material lithium cobaltoxide is investigated. READ MORE

  4. 3. Design and Evaluation of a Novel Conveyor Utilizing a Screw Mechanism to Move Objects With Integrated Racks

    University essay from KTH/Mekatronik

    Author : Måns Nilsson; Mathias Nils Edvin Nordqvist; [2021]
    Keywords : Screw Conveyor; Intralogistics; Material Handling; Thread Meshing; Worm rack drive; Brushless motor; Skruvtransportör; Intralogistik; Materialhantering; gängingrepp; Snäckskruv och kuggstång; borstlös motor;

    Abstract : Intralogistics, or material handling, traditionally use roller or chain conveyors to moveo bjects and goods in factories and warehouses. One negative aspect of the traditional types of conveyors is that they are expensive, as they are comprised of many moving parts. READ MORE

  5. 4. Modeling and optimisation of a rotary kiln reactor for the processing of battery materials

    University essay from KTH/Kemiteknik

    Author : Danial Khawaja; [2021]
    Keywords : Granular flow; rolling mode; suspension model; two-fluid model; multiphase flow; Granulärt flöde; rullningsläge; suspensions modell; tvåvätskemodell; flerfasmodell;

    Abstract : Roterugnar är cylindriska kärl som används för att höja materials temperaturer i en kontinuerlig process som kallas för kalcinering. Roterugnar kan tillämpas i olika processer såsom reduktion av oxidmalm samt återvinning av farligt avfall. READ MORE

  6. 5. Evaluation of 25 MHz Ultrasonic Testing for Detection of Non-Metallic Inclusions in Steel

    University essay from KTH/Materialvetenskap

    Author : Henrietta Isaksson; [2021]
    Keywords : Ultrasonic Testing; High Frequency Ultrasonic Testing; Quantification of inclusions; Fatigue Testing; Ultraljudstestning; Högfrekvent ultraljudstestning; Kvantifiering av inneslutningar; Utmattningstestning;

    Abstract : Quantification of inclusions is important since it is correlated to the steel’s fatigue properties. One method that could be further developed for detection of inclusions in steel is ultrasonic testing (UST). READ MORE
