The rise of PAMPA

Expert Opinion on Drug Metabolism and Toxicology, 2005
The parallel artificial membrane permeability assay (PAMPA), as a passive-permeability screen, is a possible low-cost alternative to cellular models for the earliest ADME primary screening of research compounds. Its popularity in the industry has risen rapidly. This review examines state-of-the-art PAMPA methods.

Potential of grazing management to improve beef cattle production and mitigate methane emissions in native grasslands of the Pampa biome.

Science of the Total Environment, 2021
We tested the hypothesis that improving sward structure through adjustments in forage allowance results in greater forage intake and live weight (LW) gains by beef cattle and lower CH4 emissions per unit LW gain and unit area in a native grassland ...

Hydrogeochemical controls on the mobility of arsenic, fluoride and other geogenic co-contaminants in the shallow aquifers of northeastern La Pampa Province in Argentina.

Science of the Total Environment, 2020
Elevated Arsenic (As) and Fluoride (F) concentrations in groundwater have been studied in the shallow aquifers of northeastern of La Pampa province, in the Chaco-Pampean plain, Argentina.

Experimental catchments in the Pampa biome: Database on hydrology in grasslands and eucalyptus plantations in subtropical Brazil

Hydrological Processes, 2021
The introduction of exotic, fast‐growing forest species in the Pampa biome (Southern Grasslands) is a controversial topic, considering the potential effect on water and soil resources.

Protected Areas of the Pampa biome presented land use incompatible with conservation purposes

, 2021
Currently, only 40% of Brazil’s Pampa still is covered by original vegetation; however, there is a clear underrepresentation of regional biodiversity in protected areas (PA).

Bound preserving Point-Average-Moment PolynomiAl-interpreted (PAMPA) scheme: one-dimensional case

Communications in Computational Physics
We propose a bound-preserving (BP) Point-Average-Moment PolynomiAl-interpreted (PAMPA) scheme by blending third-order and first-order constructions. The originality of the present construction is that it does not need any explicit reconstruction within ...

Modern pollen source and spatial distribution from surface lake sediments in the southwestern Pampa grasslands, Argentina: Implications to interpret Holocene pollen records

Review of Palaeobotany and Palynology, 2020
In the Pampa grasslands of Argentina nothing is known about the transport, deposition and spatial distribution of pollen in lakes. To analyze and understand how well lake surface sediment pollen assemblages reflect the contemporary vegetation in relation
