Influence of Mandibular Fixed Retainers on Diagnostic Quality of Cranial MRI
… scans with each of the five test trays in place. T1 sagittal (T1), T2 axial (T2), gradient echo (GRE), and diffusion weighted imaging (DWl) were evaluated independently by three neuroradiologists for degree of distortion and diagnostic ability. The Freidman test, a repeated measures one-way ANOVA …

Characterising Adsorption and Mass Transfer in Porous Media
… of simulating 2D signal attenuation data for T1-T2, D-T2 and T2-T2 experiments. Common artefacts were also discussed by means of experimental and simulated examples and, where appropriate, methods have been introduced for their prevention. The NMR relaxation behaviour of water saturating the …

NMR Studies of Enhanced Oil Recovery Core Floods and Core Analysis Protocols
… relaxation time measurements (L-T1-T2) have been applied to studying a special core analysis laboratory (SCAL) protocol, used for simulating reservoir oil saturations following initial oil migration (primary drainage) and characterising core samples (capillary pressure curves). …

Ultra-high field (7T) magnetic resonance fingerprinting
… parametric mapping produces maps of tissue T1, T2 and other parameters in standard units rather than the weighted images normally produced in MRI. This has advantages by facilitating multi-site studies, long-term investigations, and making it easier to detect diffuse disease. At 3T, the …

Soil-Geomorphology and Soil-Stratigraphy in the Lower Pomme De Terre River Valley, Southwestern Missouri
… 4 distinct terraces or terrace complexes, T0, T1, T2, and T3. Soils found on these terraces show a chrono-sequence with entisols dominating T0, inceptisols and alfisols with weak argillic horizons dominating T1, mollisols and alfisols with strong argillic horizons dominating T2, and a surface …

Role of adsorption in catalysis: applications of NMR relaxometry
… programmed desorption (TPD) as well as 13C T1 NMR and 1H 2D T1-T2 relaxometry methods were employed. Energies of adsorption as a function of coverage were obtained via adsorption isotherms and the particular surface adsorbate interactions were described with IR spectroscopy. For example, …

Tissue Parameter Mapping in Children with Fetal Alcohol Spectrum Disorders
… clearly understood. MRI relaxation parameters T1, T2, T2* and proton density (PD), are basic tissue properties that reflect the underlying biology. The present study aims to advance our understanding of how PAE alters the microstructural properties of tissue by examining PAE-related changes in …

The effect of Fast Eccentric Squats on measures of strength, power and speed
… and decreased DJ flight time (FT) from BL to T1, T2 and T3. The findings from this study suggest that training with an increased eccentric movement velocity during isoinertial barbell back squats, leads to no added benefit to strength, power or speed compared to traditional training.
