Linear projection‐based chemical exchange saturation transfer parameter estimation [PDF]

NMR in Biomedicine, 2022
Isolated evaluation of multiparametric in vivo chemical exchange saturation transfer (CEST) MRI often requires complex computational processing for both correction of B0 and B1 inhomogeneity and contrast generation. For that, sufficiently densely sampled Z‐spectra need to be acquired.

Estimating Base Saturation Flow Rate for Selected Signalized Intersections in Al-Najaf City [PDF]

E3S Web of Conferences, 2023
The correct saturation flow rates for the specific circumstances must be used to calculate delays and the level of Service at intersections. As a result of a lack of local data, practitioners would often use default values from overseas software ...

Mitigation of the Gradient of Chemical Properties in the Rooting Zone of Dystrophic Oxisols by Gypsum and Lime Inputs under a No-Till System

Revista Brasileira de Ciência do Solo
Improvement of soil chemical properties in dystrophic Oxisols managed under long-term no-tillage system (NTS) with surface broadcast lime has been, frequently, restricted to a shallow topsoil layer.

Soil and Vegetation Drive Sesquiterpene Lactone Content and Profile in Arnica montana L. Flower Heads From Apuseni-Mountains, Romania

Frontiers in Plant Science, 2022
Arnica montana L. (AM, Asteraceae) is a perennial, herbaceous vascular plant species of commercial importance. The flower heads’ pharmacological properties are attributed mainly to sesquiterpene lactones (SLs), with phenolic acids and flavonoids also ...

Numerical simulations of the Princeton magneto-rotational instability experiment with conducting axial boundaries

, 2016
We investigate numerically the Princeton magneto-rotational instability (MRI) experiment and the effect of conducting axial boundaries or endcaps. MRI is identified and found to reach a much higher saturation than for insulating endcaps. This is probably

Convective overstability in accretion disks: 3D linear analysis and nonlinear saturation [PDF]

, 2014
Recently, Klahr & Hubbard (2014) claimed that a hydrodynamical linear overstability exists in protoplanetary disks, powered by buoyancy in the presence of thermal relaxation.

Reversal of Forest Soil Acidification in the Northeastern United States and Eastern Canada: Site and Soil Factors Contributing to Recovery

Soil Systems, 2020
As acidic deposition has decreased across Eastern North America, forest soils at some sites are beginning to show reversal of soil acidification. However, the degree of recovery appears to vary and is not fully explained by deposition declines alone.

Relações entre os tipos e indicadores de acidez do solo em lavouras no sistema plantio direto na região do Planalto do Rio Grande do Sul Relationships among acidity types and indicators in soils under no-tillage system in the Rio Grande do Sul Planalto Region

Revista Brasileira de Ciência do Solo, 2008
A recente mudança no sistema de cultivo do solo ocorrida no Brasil, passando do preparo convencional (PC) para o sistema plantio direto (SPD), altera o funcionamento do solo. No solo cultivado no SPD, as relações se estabelecem no tempo e são preservadas
