THE INTERPLAY BETWEEN CATION ORDERING AND ELASTICITY OF OMPHACITES TO UNRAVEL PTT PATHS OF METAMORPHIC ROCKS
Omphacite, a clinopyroxene stable across a diverse range of pressure and temperature conditions, is one of the main rock-forming minerals of eclogites and is also found in blueschist facies and ultra-high-pressure rocks. Its widespread occurrence makes it a valuable candidate for Raman elastic …

The Use of Expert Pilot Performance Models to Facilitate Cockpit Visual Scan Training
… II, we therefore examined a range of ADI PTT training regimes that explicitly varied the extent to which this training is dynamic, and also which explicitly considered the training of pursuit movements. An additional feature of Experiment II, missing from Experiment I, was a systematic …

Genetic and Biochemical Analysis of Phosphinothricin Tripeptide Biosynthesis in Streptomyces Viridochromogenes
… this thesis work established that step III of PTT biosynthesis is the reduction of phosphonoacetaldehyde to hydroxyethylphosphonate by PhpC, an alcohol dehydrogenase with a previously unrecognized role in PTT biosynthesis. We also demonstrated that step IV of PTT biosynthesis is the conversion …

Flow of viscoelastic fluids through banks of cylinders: an experimental and numerical investigation
… equations, the Phan-Thien and Tanner (PTT) model and the Rivlin-Sawyers (RS) model with the Pap ana sta siou, Scriven, and Macosko (PSM) damping :function. The constitutive equations were fit to the steady shear viscosity of a LLDPE melt and a LDPE melt. The PTT and RS models were also …

The Relationship Between State Dissatisfaction and the Level of Conflict In State Dyads: the Revised Power Transition Theory
… of the occurrence? Power Transition Theory (PTT) argues that power parity and state dissatisfaction are the two necessary conditions for a state to initiate a war. However, it can only explain wars among major power states. This study aims to expand the explanatory and predictive power of PTT …

Pulmonary diffusion limitation, V̇ /Q̇ mismatch and pulmonary transit time in highly trained athletes during maximal exercise
… (VA/Q) mismatch, pulmonary transit times (PTT) and pulmonary gas exchange during exercise, 10 highly trained male athletes (age=26.4±4.4 years, Height=185.5±5.3cms, Weight=78.2±8.6 kg, V 02max=5.15±0.521-min-1) under went exercise testing at rest (R) and 150W, 300W and maximal exercise …

Comparison of anaerobic and aerobic fatigue on visual skills
… a prolonged incremental maximal treadmill test (PTT) immediately followed by the sports vision test battery. In the SCT, significant (p ≤ 0.05) changes were found for five of the six sports vision performance measures (p = 0.000), except visual memory (p = 0.242). In turn, following the PTT, …

Single-site, noninvasive, blood pressure measurements at the ear using ballistocardiogram (BCG), and photoplethysmogram (PPG), and a low-power, reflectance-mode PPG SoC
… be obtained, known as the pulse transit time (PTT), from a single site of measurement. The ear-worn device is wirelessly connected to a computer for real-time data recording. A clinical test involving hemodynamic maneuvers is performed on 15 subjects. The results demonstrate a linear …

Linear regression model for continuous non-invasive blood pressure estimation for an ICU setting
… and contraindicated. Current pulse transit time (PTT)-based BP estimation methods are validated on healthy subjects using intermittent cuff-based BP measurements. Research indicates significant differences in invasive and noninvasive BP recordings in critically ill patients. Research also …

The development of an algorithm to track blood pressure accurately based on the pulse transit time method
… been developed based on the Pulse Transit Time (PTT) method, which would allow non-invasive and continuous BP measurement. PTT is defined as the time it takes the BP wave to propagate from the heart to a specified point on the body. After an initial BP measurement, PTT algorithms can track BP …

Investigation of the biosynthesis of the phosphonate antibiotics bialaphos and dehydrophos
… their metabolic pathways. One of such compounds, PTT, contains unusual amino acid phosphinothricin attached to two alanine residues. The peptide bond formation and methylation on phosphorus in PTT are key steps in PTT biosynthesis, however, the exact timing of these transformations was not known. …

NANOPARTICLE BASED MULTI-MODAL THERAPIES AGAINST TRIPLE-NEGATIVE BREAST CANCER
… can be enhanced by using photothermal therapy (PTT) and ionizing radiation in combination with the AgNP. We show that AgNPPs can be used to develop a selectively cytotoxic multimodal therapy against TNBC cells line without affecting non-tumorigenic cells. Combining the cytotoxicity of the …

Predicting rejection rates of electric distribution wood pole assets
… wood utility poles. The Pole Test & Treat (PTT) program at PG&E is responsible for inspecting these poles, prolonging their service life through the use of chemical treatments or structural reinforcements, and identifying poles that need to be replaced. Following industry best practices and …

Induction of Immunogenic Cell Death via Nanoparticle-Mediated Dual Chemotherapy and Photothermal Therapy
… for combinatory chemo-photothermal therapy (PTT) to induce immunogenic cell death (ICD) and target the medication to the tumor site. ICD overall causes the activation of dendritic cells (DC) and T cells to initiate an antitumor immune response and is characterized by the presentation of …

Design strategies and application of stimuli-responsive nanoparticles for cancer diagnosis and therapy
… nanoparticles (NPs) for photothermal therapy (PTT) of melanoma. Results showed that 5 kDa polyethylene glycol (PEG) coated gold nanorod provided the highest colloidal stability and maximum photothermal efficiency compared to the low (2 kDa) and high mass of PEG (10 kDa) used when treated with …
