PERFORMANCE - LIGHT SATURATION CURVE FOR GRAPEVINE PHOTOSYNTHESIS [PDF]

open access: yesScientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2021
Performance - Light saturation curve for photosynthesis is determined by the genetics of grapevine genotypes, through the physiological element - the degree of penetration of leaves by solar radiation, photosynthesis intensity, leaf structure ...

The luminous late-time emission of the type Ic supernova iPTF15dtg - evidence for powering from a magnetar? [PDF]

open access: yes, 2018
iPTF15dtg is a Type Ic supernova (SN) showing a broad light curve around maximum light, consistent with massive ejecta if we assume a radioactive-powering scenario.

Starspot signature on the light curve: Learning about the latitudinal distribution of spots [PDF]

open access: yes, 2016
Quasi-periodic modulations of the stellar light curve may result from dark spots crossing the visible stellar disc. Due to differential rotation, spots at different latitudes generally have different rotation periods.

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Modeling of the Super-Eddington Phase for Classical Novae: Five IUE Novae

open access: yes, 2006
We present a light curve model for the super-Eddington luminosity phase of five classical novae observed with IUE. Optical and UV light curves are calculated based on the optically thick wind theory with a reduced effective opacity for a porous ...

The Orbital Light Curve of Aquila X-1 [PDF]

open access: yes, 2000
We obtained R- and I-band CCD photometry of the soft X-ray transient/neutron- star binary Aql X-1 in 1998 June while it was at quiescence. We find that its light curve is dominated by ellipsoidal variations, although the ellipsoidal variations are ...

Characterization of variability in blazar light curves [PDF]

open access: yesAstronomische Nachrichten, 2020
AbstractBlazars represent the dominant population of the extragalactic γ‐ray sources in the universe. These sources exhibit some characteristic properties such as strong and nonthermal continuum emission over the entire electromagnetic spectrum, from radio to Tera electron Volts (TeV) γ‐rays, with rapid variability on all timescales.

THE LIGHT CURVE OF THE MACRONOVA ASSOCIATED WITH THE LONG–SHORT BURST GRB 060614 [PDF]

open access: yes, 2015
The Swift-detected GRB 060614 was a unique burst that straddles an imaginary divide between long- and short-duration gamma-ray bursts (GRBs), and its physical origin has been heavily debated over the years.

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.
