Rock fracture under static stress conditions
… of rock fracture, particularly under compressive stress conditions, is of fundamental importance. This thesis contains details of an investigation into the applicability of Griffith's brittle fracture theory, modified to account for the effects of crack closure in compression, to the prediction of …

Numerical Simulation of Reinforced Concrete Subjected to Multiaxial Stress Conditions
… (2) crack modeling in concrete; (3) interface stress and stiffness transfer across the crack; and (4) finite element implementation of the findings into an integrated program. Comparison of numerical results with actual test results are presented to verify this proposed algorithm.

Pressure, temperature, and stress conditions of Southern Alpine Fault (New Zealand) mylonites
… 𝜇m in mylonitic quartz indicating differential stress values in the south of ~100 MPa, roughly twice the stress values observed in the central Alpine Fault. Constraints from Ti-in-quartz thermobarometry and Raman Spectroscopy of Carbonaceous Material (RSCM) indicate mylonitization occurred at …

Failure Criteria and Cumulative Damage in Fatigue Under Multi-Axial Stress Conditions
… investigations into fatigue under multiaxial stress, and also cumulative damage under uniaxial stress, are discussed in conjunction with the parameters relevant to the present experimental investigation. A biaxial fatigue machine is described which can subject thin wall tubes to combinations …

Investigating the response of the NEDD8 ubiquitin-like molecule to diverse stress conditions
… roles, we showed that NEDD8 responds to various stress conditions, such as inhibition of the 26S proteasome, heat shock and oxidative stress.<br/>Modification of proteins with ubiquitin and ubiquitin-like molecules is involved in the regulation of almost every biological process. Historically, …

Investigating the molecular mechanism whereby auxin modulates Arabidopsis thaliana growth under salinity stress conditions
… land. Salinity imposes both an osmotic and ionic stress on plants, the latter of which is unique to salt stress. Previous work has indicated that the plant growth hormone auxin could play an important role in ionic stress tolerance: transcriptome profiling revealed that the genes differentially …

An Approach to Demand Response for Alleviating Power System Stress Conditions due to Electric Vehicle Penetration
… distribution networks will face more and more stress conditions, especially as electric vehicles (EVs) take a greater share in the personal automobile market. This may cause potential transformer overloads, feeder congestions, and undue circuit failures. Demand response (DR) is gaining …

The Role of Nucleolin Phosphorylation by CK2 in Regulating Cellular Fate Under Normal and Stress Conditions
… (NCL or C23) is an abundant genotoxic stress-responsive RNA binding phosphoprotein. NCL constitutes 10% of total nucleolar protein that has functions in multiple biological processes, including ribosome biogenesis, DNA/RNA metabolism, cellular response to DNA damage, cell growth, …

Critical Erosion/Corrosion Piping Wall Thicknesses Under Static and Fatigue Stress Conditions According to ASME Guidelines
… additions to be implemented are four alternating Stress-to-Number of cycles curves: Aluminum 1100, Aluminum 3003-0, Aluminum 6061-T6, and Nickel 200. In addition, procedures of the ASME for fatigue curve analysis and implementation of fatigue data were investigated. These four stress-to-number of …

Exploration of the transcriptomes and functional contributions of Listeria monocytogenes plasmids during food production-associated stress conditions
… when cells were exposed to FPE-associated stress conditions. Much is known of the chromosomally-encoded molecular mechanisms of L. monocytogenes that increase tolerance to FPE-associated stress conditions. However, our understanding of the stress response roles of L. monocytogenes plasmids …

Role of BTG2/TIS21/PC3 in differentiation of myeloid leukemia cells and its regulation under stress conditions
… in Btg2 transcription in response to cell stress challenges such as serum deprivation and oxidative stress i.e. H2O2, or doxorubicin treatments. We observed close interrelation between generation of reactive oxygen species (ROS), enhanced IκBα degradation, nuclear translocation of …

The effect of seaweed concentrate on turfgrass growth, nematode tolerance and protein synthesis under moisture stress conditions
… determine the effects of salinity and moisture stress on the pathogenicity of root-knot nematodes (RKN) in turfgrass plants. The results indicated that RKN infection adversely affected both visual and functional parameters of bentgrass. Salinity and moisture stress further exaggerated the damage …

PTEN regulates the BMI1-mediated self-renewal of long-term hematopoietic stem cells in developmental and stress conditions
… to resist the threats posed by various types of stress. However, our understanding of LT-HSCs under stress is still limited. It has been observed in our laboratory that the deletion of Pten in the LT-HSCs of VE-cadherin-cre+;Ptenfl/fl mice does not lead to the loss of HSC self-renewal, raising …
