Czy powstanie międzynarodowa definicja obszaru wiejskiego w Europie?

open access: yesWieś i Rolnictwo, 2008
Teoretyczna definicja obszarów wiejskich stanowi klasyczny temat studiów akademickich w dziedzinie geografii. Pojawia się jednak również jako coraz bardziej potrzebne narzędzie przy ocenie polityki i rozwoju obszarów wiejskich na szczeblu krajowym i ...

Tidal evolution of planetary satellites [PDF]

open access: yes
Early in the history of the Solar System, Europa and Ganymede may have evolved through a 3:1 mean-motion commensurability, which would have been encountered prior to the establishment of the current Laplace resonance involving Io, Europa, and Ganymede ...

Pebble accretion at the origin of water in Europa

open access: yes, 2017
Despite the fact that the observed gradient in water content among the Galilean satellites is globally consistent with a formation in a circum-Jovian disk on both sides of the snowline, the mechanisms that led to a low water mass fraction in Europa ...

Susceptibility to cyflumetofen in populations of the citrus leprosis mite, Brevipalpus yothersi, from Brazilian citrus orchards

open access: yesPest Management Science, EarlyView.
Brevipalpus yothersi, the vector of citrus leprosis virus, showed high susceptibility to cyflumetofen. Its low resistance suggests it is effective, but should be rotated with other acaricides with different modes‐of‐action for sustainable management.

Infrared observations of small solar-system bodies [PDF]

open access: yes
A major accomplishment during last year is the recongition of and modeling of the solid-state greenhouse effect for icy satellites. Recent observations of eclipse reappearances suggest that this effect may in fact be observed on Europa and Ganymede. Also

Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...
