Influence of Mineral Particle Films and Biomaterials on Guava Fruits and Implications for the Oviposition of Anastrepha obliqua (Macquart) (Diptera: Tephritidae)

open access: yesInsects, 2021
Anastrepha obliqua (Macquart, 1835) is an important pest of tropical fruits, especially Anacardiaceae and Myrtaceae, in the Americas. The objective of this study was to evaluate the influence of mineral films and biomaterials on the coloring of guava ...

Luminosity- and morphology-dependent clustering of galaxies [PDF]

open access: yes, 2000
How does the clustering of galaxies depend on their inner properties like morphological type and luminosity? We address this question in the mathematical framework of marked point processes and clarify the notion of luminosity and morphological ...

The Stars of Low Luminosity [PDF]

open access: yesProceedings of the National Academy of Sciences, 1952
A search has been made among the faint stars with large proper motion found on the Palomar Survey plates for objects that, statistically—judging from their magnitude, color, and proper motion—would appear to be fainter than one ten-thousandth of the sun's luminosity.

Nitrogen supply and shading affect morphology and composition of the essential oil in marigold (Tagetes erecta L.)

open access: yesFolia Horticulturae, 2020
Terrestrial plants are constantly exposed to multiple environmental signals that influence their metabolism. Among these signals, nitrogen (N) nutrition and light affect importantly diverse metabolic and physiological processes. Herewith the effects of N

How cutting types and shading levels influence the vegetative propagation of Pereskia aculeata?

open access: yesBrazilian Journal of Biology, 2023
Information from Pereskia aculeata Miller (Cactaceae) responses regarding the portion of the stem cuttings branch parental plants and the shading level need to be investigated in order to establish techniques for their producing seedlings.

Thermal Energy and Luminosity Characterization of an Advanced Ignition System Using a Non-Intrusive Methodology in an Optically Accessible Calorimeter

open access: yesEnergies, 2023
To restrain the environmental impact of modern SI engines, igniters must guarantee stable combustions with low cycle-to-cycle variability in extreme operating conditions (high EGR, ultra-lean), via high energy release in the combustion chamber.
