Geospatial analysis of specific degradation in South Korea
… upland erosion, rills and valleys, aggradation/degradation, and flood plain sediment deposition. These problems vary in space and time, therefore a reliable and consistent approach to model sediment processes is desirable. In contrast to sediment yield at the basin scale, Specific Degradation …

Addressing electrode-specific degradation in the production and performance of electrochemical energy storage systems
… and climate change by examining the life cycle (degradation) of electrochemical energy storage devices. Specifically, it investigates a green synthesis technique for high-performance pseudocapacitor electrodes and uses machine learning algorithms to predict and prevent degradation mechanisms in …

Theory of mRNA degradation
… in 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 …

Engineering Cell Lines to Investigate the Function of Mammalian SWI/SNF Complexes
… aim, we have developed a conditional protein degradation approach in mouse embryonic stem cells. This enables substantial depletion of the target subunit within two hours. Immunoprecipitation of complexes depleted for SWI/SNF components showed specific degradation of the targeted subunit. The …

Chemical Characterization of the Degradation of Necromass from Four Ascomycete Fungi: Implications for Soil Organic Carbon Turnover and Storage
… thought, very little is known about the specific degradation patterns of fungal necromass, and subsequently its potential chemical contributions to long-lived SOM pools. This study addresses these knowledge gaps through a time-series analysis of the degradation patterns of fungal tissue …

In vitro proteolysis of ovine lens crystallins by calpain II : A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Science with Honours
… worldwide and it is thought that calpain-induced degradation of the major lens proteins, the crystallins, is an important component in many types of cataract.. At Lincoln University, a heritable cataract in sheep is being studied. The aim of this project was to set up an in vitro system to …

Statistical Modeling, Learning and Computing for Stochastic Dynamics of Complex Systems
… the probability that a system fails due to a specific degradation process when degradation processes are independent dependent. It also explains how to model the degradation of each process when they subject the system to constant but varying rate failure. The second goal is to model the …

Diacylglycerol lipaseα-dependent endocannabinoid signaling in neural stem cells
… and we investigated the possibility of a specific degradation pathway being involved. DAGLα has a consensus motif for a putative destruction (d-) box that might target DAGL for ubiquitin-proteasome mediated degradation. No evidence was found to support that the d-box is involved in DAGLα …

Vestibular Evoked Myogenic Potentials and Postural Control in Adults with Age-Related Hearing Loss
… attributed to, through histopathological study, specific degradation of the sensory, supporting, and afferent structures of the cochlea. Vestibular function, as measured through vestibular evoked myogenic potentials (VEMPs) also show decreases with age. VEMPs are a measurement of evoked …

An investigation of the factors affecting the degradation of cellulose acetate artefacts in museum collections
… These plastics are already exhibiting signs of degradation, which raises the question of how they should be stored and treated. However, little is known about the specific degradation processes which occur. Further research is required because the lack of information is hindering the correct …

Morphological and Neuroanatomical Changes Associated with the Induction of Neurodegeneration and Life Span Reduction in Drosophila melanogaster by Glia Targeted Expression of Cdh1/Rap/Fzr, An Activator of the Anaphase Promoting Complex
… (APC/C). APC/C facilitates the cell cycle stage-specific degradation of cyclins and other mitotic regulators, resulting in the inactivation of Cdk (Cyclin Dependent Kinase) complexes, thus promoting completion of mitosis. Previous studies from our laboratory have shown that Rap/Fzr (the …

The Role of a Neuron-Specific V-ATPase in Synapse Specification, Function, and Maintenance
… for this includes a null allele for the neuron-specific a subunit in the Drosophila Vo sector, v100, which leads to defects in synaptic function that are unrelated to pH regulation. My project emerged from the need to explain why v100 has two additional phenotypes that are absent in other …

Proteolysis of mammary secretion proteins during involution of bovine mammary gland
… in all fractions after isoelectric focusing, but specific degradation products of lactoferrin were apparent only at certain times during the dry periods. Plasmin, plasminogen and plasminogen activator activities were significantly higher ($P <$ 0.05) on d 7, 14 and 21 of involution compared to d 7 …

Copolymerisation of polyesters using reactive extrusion
… such as undesirable colour waste and material degradation after repeated cycles, which limit its long-term effectiveness. Meanwhile, bioplastics such as polybutylene adipate-co-terephthalate (PBAT) offer sustainable alternatives but are constrained by their high costs and reliance on a specific …

Materials and biological approach to gene delivery in human embryonic stem cells
… a system that uses the combination of a cell specific and materials approach. Plasmid DNA was condensed with PVBLG-8 to form nanocomplexes, which were further coated with hyaluronic acid. PVBLG-8 has proven to be an effective gene delivery material in certain cell lines, due to its membrane …

Investigation of Diverse CARF Effectors in Type III CRISPR - Cas Immunity
… create an RNA-guided nuclease that mediates site-specific degradation of invader DNA or RNA that is complementary to the crRNA. The type III CRISPR-Cas system is also able to synthesize a cyclic small molecule from ATP through the cyclase domain of Cas10. This molecule, termed cyclicoligoadenylate …

Synthesis of internal amide bond short interfering RNAs (siRNAs) and investigation of their gene silencing properties
… The next generation of cancer therapeutics will specifically target processes responsible for the growth and survival of cancer cells. Among the most promising of these molecularly-targeted therapeutics are short interfering RNAs (siRNAs). These siRNAs serve as the effectors of RNA interference, …
