  2. 1. Synthesis and Reactivity Studies of Zwitterionic Silenes and 2-Silenolates

    Author : Tamaz Guliashvili; Henrik Ottosson; Kim M. Baines; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Silicon; Zwitterionic Silene; 2-Silenolate; Diels-Alder Reaction; Silacyclohexene; X-ray Crystallography; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes synthesis and reactivity studies of 2-amino-2-siloxysilenes and 2-silenolates, species that are strongly influenced by reversed Si=C bond polarization, i.e. an Siδ-=Cδ+ polarization as compared to the natural Siδ+=Cδ- polarization. READ MORE

  4. 2. Deep Learning for Active Fire Detection Using Multi-Source Satellite Image Time Series

    Author : Yu Zhao; Yifang Ban; Andrea Nascetti; Josephine Sullivan; Cartalis Constantinos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wildfire; Remote Sensing; Active Fire Detection; GOES-R ABI; Suomi-NPP VIIRS; Image Segmentation; Deep Learning; Gated Recurrent Units GRU ; Transformer.; Vilda Bränder; Fjärranalys; Aktiv Branddetektering; GOES- R ABI; Suomi-NPP VIIRS; Bildsegmentering; Djupinlärning; Gated Recurrent Units GRU ; Transformer; Geoinformatik; Geoinformatics;

    Abstract : In recent years, climate change and human activities have caused increas- ing numbers of wildfires. Earth observation data with various spatial and temporal resolutions have shown great potential in detecting and monitoring wildfires. READ MORE

  5. 3. Prediction, Design and Determination of Protein Structures

    Author : Sebastian Rämisch; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein design; Rosetta; Fold-and-Dock; leucine rich repeat proteins; coiled-coils; molecular replacement; ab initio phasing; temperature stability; fluorescent proteins;

    Abstract : The three-dimensional structure of protein is encoded in its amino acid sequence. Modern structure prediction algorithms make it possible to predict the structure of small proteins using sequence information alone. READ MORE

  6. 4. Probing the effect of UV radiation on the chemistry in circumstellar envelopes around evolved stars

    Author : Maryam Saberi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stars: abundances - Stars: AGB – Stars: individual: R Scl – Stars: binaries – Stars: carbon – Stars: circumstellar matter – Stars: chromospheres – Ultraviolet: stars;

    Abstract : Low to intermediate mass (0.8 - 8 M⊙) stars lose a substantial amount of their mass in the last phase of stellar evolution, the asymptotic giant branch (AGB) phase. Hence, they are one of the main suppliers of dust and gas in the interstellar medium and important for the enrichment of galaxies. READ MORE

  7. 5. Alkoxide complexes of rhenium - precursors of nanomaterials

    Author : Olesya Nikonova; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The thesis presents the work constituted by two major parts: (1) – synthesis of new mono-, bi- and trimetallic complexes based on Re, Nb and Ta and their physical-chemical characterization, and (2) – preparation of nanostructural functional materials derived from these complexes. The precursors and materials were characterized by FTIR, NMR, MS, SEM–EDS, TEM and X-ray diffraction. READ MORE
