Newly Designed HNO Triggered Prodrugs
Nitric oxide (NO) is an important species in many biological processes. The one-electron reduced and protonated derivative of NO, HNO has also been determined to play important biological roles. Because of HNO’s high reactivity, its detection has been difficult and many methods including …

Calcium Triggered Synaptic Vesicle Exocytosis
Neurotransmitter release is triggered by the action potential induced influx of Ca 2+ into nerve terminals. One of the central questions in neuroscience is how Ca 2+ promotes synaptic vesicles from rest to fusion leading to release of neurotransmitters. In this thesis, I first addressed if …

Preschoolers' endogenously triggered self-regulation
… was to explore children's self-regulation when triggered by both internal and environmental factors. The majority of participants were able to demonstrate regulation in at least one domain. For almost half of the participants however, the ability to demonstrate regulation depended on whether the …

Reductively triggered internal cyclisation reactions
Reductively triggered internal cyclisation reactions have been investigated as a prodrug system for the hypoxia selective release of aromatic nitrogen mustards. The observed pseudo-first-order rate coefficients of cyclisation of several model 2-aminoaryl-acetamides and propanamides have been …

Microwave Triggered Laser Ionization of Air
In this thesis the measurements and analyses of high power electromagnetic wave interaction with a laser-induced plasma (LIP) have been investigated. The laser-induced breakdown processes in air generated by focusing a 600 mJ, 7 ns pulselength, 1064 nm wavelength Nd:YAG laser onto a 30 μm spot size …

pH-Triggered Membrane Insertion of Proteins
… in unraveling the molecular mechanisms of pH-triggered insertion of membrane proteins, many aspects of this process remain unknown. In this study we used two proteins that share structural similarities as model systems: the diphtheria toxin translocation domain (T domain) and the …

Optically triggered thyristor for capacitor discharge applications
An investigation of the use of light to trigger semiconductor thyristors for capacitor discharge applications has been conducted. The investigation consisted of a technical literature and background search, design and analysis of optically silicon thyristors, and simulations of a capacitor …

CO2-Triggered Switchable Solvent Systems and Their Applications
This thesis begins with the introduction of solvents and their classification. The two solvent system studied here are switchable polarity solvents (SPS). A switchable polarity solvent is a liquid where its polarity can change between two forms by a trigger. These two solvent systems have several …

Time-Lapse Polymerizations Triggered by pH clock Reactions
… theme of this work is time-lapse polymerizations triggered by pH clock reactions. The first chapter is the introduction and gives a long overview of the different chemistries studied here. The second chapter focuses on the bromate-sulfite clock reaction. Based on some simplified and accepted …

Characterisation of potential regulators of PAMP-triggered immunity
… and pie knock-down lines display reduced PAMP-triggered responses, indicating that an optimal PIE expression level is required for proper induction of signalling. All together, these results imply that PIE is a novel regulator of the EFR and FLS2 signalling pathway.

Tetrazine-Triggered Bioorthogonal Decaging Reactions for Prodrug Activation
… describes the application of the tetrazine-triggered IEDDA reaction to cleave protecting groups from carboxylic acid- and alcohol-containing molecules. The first project relates to the development of both vinyl and trans-cyclooctene (TCO) protecting groups to mask a carboxylic …

Detection of Polypeptide Interactions Via Periodate Triggered Dopa Crosslinking
Protein-Protein interactions mediate most biological function, yet elucidation of the molecular architecture within a cell still remains a formidable challenge for molecular biologist. We have developed a novel, bioorthogonal cross-linking chemistry based upon periodate mediated oxidation of the …

Event-triggered near optimal adaptive control of interconnected systems
… nonlinear interconnected systems with event-triggered feedback. Distributed NN identifiers are introduced both for approximating the uncertain nonlinear dynamics and to serve as a model for online exploration. Next, the control policy and the event-sampling errors are considered as …

The Diversity of TLR4-triggered Responses in Mouse Microglia
Mikroglia repräsentieren den vorherrschenden Immunzelltyp im ZNS. Während der steten Überwachung der Mikroumgebung sind diese Zellen jederzeit bereit, vom ruhenden in einen aktivierten Status zu wechseln. Dies geschieht insbesondere nach dem aufspüren von "Gefahr"-assoziierten Signalen, wie dem …

PH-responsive polymeric materials for encapsulation and triggered release
… polymeric materials for encapsulation and triggered-release. As a release trigger, pH is attractive because of the prevalence of environments with specific pH levels. In the first part of the dissertation, a diester diacid chloride monomer, PDDC, was utilized in the preparation of a novel …

A self-triggered readout for a time projection chamber
A self-triggering readout for a time projection chamber (TPC) is presented, with applications to novel forms of data acquisition for high energy physics application. The construction and initial testing of the readout electronics are described, as well as the readout implementation in a prototype …

Enediynylacridans: design and synthesis of oxidase triggered diyl progenitors
In 1972, Bergman reported cycloaromatization via 1,4- benzenoid diradicals of enediyne systems. Since 1985, five enediyne fungal products with anticancer antibiotic activity have been structurally elucidated, namely, neocarzinostatin chromophore, the calicheamicins, the esperamicins, the …

Numerical modeling of resonant internal seiche triggered by unsteady withdrawal
… lake or reservoir. The resonant internal seiche triggered by unsteady withdrawal is studied numerically in this thesis using the C/C (Cloud-In-Cell) method. The investigation is concerned with internal seiches in a viscous, incompressible and weakly stratified fluid which is confined within a …
