  1. 1. Attitude and orbit control analysis of a solar sail spacecraft for Space sunshade missions in the vicinity of the sub-Lagrange 1 point

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Benjamin Jouanneau; [2022]
    Keywords : ;

    Abstract : This Master thesis report contains a complete attitude and orbit control analysis for solar sail spacecraft in the Circular-Restricted-3-Body-Reference frame. The overall goal of the project is to drive one solar sail from the edge of the Earth Sphere of Influence to a vicinity of the sub-Lagrange1 point. READ MORE

  2. 2. Evaluating LOAd703 in combination with chemotherapeutic agents in ovarian cancer

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för immunologi, genetik och patologi

    Author : Jonas Härdin; [2022]
    Keywords : Clinical Immunology; Immunotherapy; LOAd; Ovarian Cancer; Oncology; Virus;

    Abstract : Ovarian cancer is a disease with a high rate of mortality where the need for novel treatments will increase in the near future as older and populous generations reach the age where the cancer is usually diagnosed. Once treated, ovarian cancer tends to recur and display a newfound resistance against the platinum-based chemotherapeutic drugs that are used to treat the disease. READ MORE

  3. 3. A Generic Software Architecture for PoE Power Sourcing Equipment

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Andreas Mäkilä; [2022]
    Keywords : power over Ethernet; software architecture; real-time requirements;

    Abstract : The IEEE Power over Ethernet (PoE) protocol is currently the most used standard for allowing Power Sourcing Equipment (PSE) to distribute power to Powered Devices (PD) through standard Ethernet cables, permitting devices to be added to a network without needing extra power cables.There exist many PSE manager circuits which can be used to easily distribute power to a handful of PDs, but a problem arises when more are desired, since very few of these circuits can communicate with other circuits, and thus can't coordinate power distribution with each other.

  4. 4. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Center for Nanoscience

    Author : Qianhui Liu; [2022]
    Keywords : Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Abstract : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  5. 5. Immunological Cross-Reactivity : Construction of a Workflow That Enables Cross-Reactivity Predictions

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Alexander Blomlöf; Alvin Unge; Petter Byström; Erika Lindberg; Torbjörn Fries; [2022]
    Keywords : Cross- reactivity; Immunology; Epitope; Paratope; Antibody; Prediction; Substitution analysis; Proximity Extension Assay; Bioinformatic tools;

    Abstract : Cross-reactivity occurs when an antibody binds to the epitope of a protein that is not the targeted antigen. This is problematic in the analysis of immunoassay diagnostics. Detecting a protein incorrectly might cause issues such as incorrect mapping of metabolic conditions for research or diagnosis. READ MORE
