Theory of mRNA degradation
… living cells, biochemists have studied specific degradation mechanisms in detail. In addition to that, modern high-throughput techniques allow to obtain quantitative data on a global scale by parallel analysis of the decay patterns of many different mRNAs from different genes. In previous …

Degradation of Piloting Skills
… The two research questions were to what extent degradation in basic instrument pilot skills occurs, and can this degradation be statistically proven? The study used two groups of pilots (wide-body and narrow body) flying five basic instrument maneuvers. The maneuvers were flown without the use …

Mechanisms of polyphosphate degradation
… exopolyphosphatases degraded polyP. To study the degradation of polyP in vivo and identify putative polyphosphatases, we needed to develop a high-throughput method for measuring polyphosphatase activity. The study of polyP long has been hampered by the paucity of high-throughput methods for …

Modelling Gas Turbine Degradation
In this thesis work will be presented which demonstrates the potential benefits and current obstacles to the creation of a geometry morphing procedure for the computational simulation of hot corrosion and related phenomenon in gas turbines using Reynolds-averaged Navier Stokes (RANS) computational …

Regulation of miRNA degradation
… relatively little is understood about miRNA degradation. Here, I describe the work that I’ve done to address this gap in our knowledge. To understand the extent that degradation rate is individually specified for miRNAs, I measured miRNA dynamics in mammalian cells. Supporting individualized …

Thermal degradation of organophosphorus compounds.
… and isolation of the products of thermal degradation. Infrared, ultraviolet, 1H nuclear magnetic resonance and mass spectra of the isolated compounds are recorded and evaluated. Structures are proposed for the isolated compounds and the spectroscopic properties of authentic samples …

Radiation induced degradation of elastomers.
… of the thermal and combined thermal/radiative degradation of a peroxide cured polydimethylsiloxane elastomer (PDMS), and a vinylidene fluoride-hexafluoropropylene elastomer (Viton E60-C),by chemical stress relaxation measurements. It was observed that the PDMS elastomer degraded thermally by …

Mechanistic Study of Pollutant Degradation
… has been a serious concern worldwide. Many degradation methods have been developed to clean sites contaminated with pollutants. More knowledge and better understanding in this field will help to protect our environment. The goal of the research in this thesis is to gain a better …

The thermal degradation of polystyrene.
A review is made of the thermal degradation of polystyrene. In a theoretical study the importance of intramolecular transfer during degradation is emphasized in the formation of oligomeric volatiles. To account for past experimental results a mechanism is proposed involving biradical cage …

Metal induced degradation of leather
… methods. Since leather is resistant to microbial degradation, direct recycling of leather waste through biodegradation methods are impractical.<br/><br/>In this research, the mechanism and potential application of metal induced oxidative degradation of leather were studied. Experimental work on …

Control of DAPK-1 degradation
… cytokine TNF-α has been reported to induce the degradation of DAPK-1. Here I identified the protease cathepsin B as a novel binding partner of DAPK-1 that protects DAPK-1 from TNF-α induced degradation. Using deletion mutants of DAPK-1, I mapped the cathepsin B binding domain on DAPK-1 to amino …

Microbial degradation of polyester polyurethane
… Vinyzene E.P. reduced the rate and extent of degradation in test material exposed to soil conditions, but was found to be ineffective in preventing degradation when exposed to the marine environment. As a result of these studies, a number of fungi, representing a range of genera, have been …

Catalytic Degradation of Waste Polymers
… readily into their monomer units. Thermal degradation of polymers usually follows a radical mechanism (which is of high energy and requires high temperatures) and produces a large proportion of straight chain alkanes, which have low relative octane number (RON) and so cannot be used in …

Engineered Vesicles for Perchlorate Degradation
This study demonstrates the use of engineered vesicles to reduce perchlorate. Specifically, cell-free extracts containing perchlorate reductase and chlorite dismutase enzymes were encapsulated in a triblock copolymer vesicle functionalized with the outer membrane porin OmpF. The porin allows for …
