Comparative analysis of three bait types in deep-set pelagic longline gear in the Equatorial Atlantic Ocean

open access: yesBoletim do Instituto de Pesca, 2022
The choice of bait is one of the fisheries tactics used to increase selectivity for particular target species. The performance of three bait types (mackerel, sardine, squid) was evaluated with a commercial vessel operating in the Equatorial Atlantic ...

Hansen Solubility Parameters (HSPs): A Reliable Tool for Assessing the Selectivity of Pristine and Hybrid Polymer Nanocomposites in the Presence of Volatile Organic Compounds (VOCs) Mixtures

open access: yesMacromolecular Materials and Engineering, 2023
Polymeric materials are widely employed for monitoring volatile organic compounds (VOCs). Compared to other sensitive materials, polymers can provide a certain degree of selectivity, based on their chemical affinity with organic solvents. The addition of

To the problem of owls’ (Strigiformes) diet selectivity

open access: yesБіологічні студії, 2012
A large body of literature covers the trophic connections of owls nowadays, but detailed studies of the diet selectivity are rather race. Any attempt to determine the cha­racter of owls’ diet selectivity, its influence on prey-species assemblages ...

The selectivity, voltage-dependence and acid sensitivity of the tandem pore potassium channel TASK-1 : contributions of the pore domains [PDF]

open access: yes, 2007
We have investigated the contribution to ionic selectivity of residues in the selectivity filter and pore helices of the P1 and P2 domains in the acid sensitive potassium channel TASK-1.

The effect of addition of a third component on the behaviour of the lithium doped magnesium catalysts for the oxidative dehydrogenation of ethane [PDF]

open access: yes, 1992
The oxidative dehydrogenation of ethane was studied with the use of promoted Li/MgO catalysts at temperatures of 600¿650°C. The addition of known promoters, cobalt and tin, gave a slight Increase In activity but a strong decrease in selectivity to ...

Selection on selected records [PDF]

open access: yesGenetics Selection Evolution, 1983
On considère le problème de la sélection d’individus pour leurs valeurs génétiques additives et de l’estimation de ces valeurs. La sélection est basée sur un vecteur d’observations faites sur un ensemble d’individus eux-mêmes issus d’une sélection sur un certain vecteur d’observations.

Investigating the selectivity of weed harrowing with new methods [PDF]

open access: yes, 2008
In six field experiments it was investigated whether row spacing, timing, direction and orientation of post-emergence weed harrowing in spring barley influenced the selectivity and whether it is important that increasing intensities of harrowing are ...

Selecting Selective Suppressors of Selective Uptake [PDF]

open access: yesChemistry & Biology, 2003
Scavenger receptor BI (SR-BI) is a high-density lipoprotein (HDL) receptor that mediates the selective uptake of HDL cholesteryl ester (CE) and the bidirectional flux of free cholesterol (FC). The identification of selective uptake inhibitors holds promise for mechanistic studies of SR-BI and for discovery of pharmaceuticals useful in therapy of ...
