Effect of Different Parameters on Charpy Impact Properties of Quasi-Isotropic Epoxy Composites Reinforced with Basalt and Glass Fibers

open access: yesJournal of Advanced Materials in Engineering, 2015
In this study, the effects of different parameters on charpy impact properties of pure and hybrid composite laminates reinforced with basalt and glass filaments were investigated.

LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Stardust Mine: A 2024 gabbroic shergottite from Arizona, USA

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract This study provides an initial characterization of Stardust Mine, a fresh gabbroic enriched shergottite collected in Arizona, USA, in September 2024 and is the first Martian meteorite to be unequivocably collected on US soil. Analysis was conducted on the type specimen and finds that Stardust Mine is composed of equal proportions of pyroxene ...

Hydrogeochemistry and hydrology of a basalt aquifer system, the Atherton Tablelands, North Queensland

open access: yes, 2004
The Atherton Tablelands basalt aquifer is a major source of groundwater supply for irrigation and other agricultural use. The Tertiary to Quaternary age basaltic aquifer can be regarded as a generally unconfined, layered system, comprising numerous ...

Virtuous Deferral

open access: yesNoûs, EarlyView.
ABSTRACT Virtue epistemology has long struggled with the “Creditability Dilemma”: how can knowledge gained through deference be creditable to the knower if it primarily depends on others’ cognitive work? We propose a novel solution by developing a telic account of doxastic deference as a distinctive kind of social‐epistemic performance.

Studies of Basalt Through Laser Induced Breakdown Spectroscopy (LIBS) for the Manufacturing of Lapilli Blocks

open access: yesMinería y Geología, 2016
Basaltic samples selected from different areas of Tenerife were analyzed by applying laser induced breakdown spectroscopy (LIBS), Raman spectroscopy and X Ray Diffraction (XRD) in order to identify the basic chemical composition and mineralogy. The basic

Organ‐specific terpenoid responses in Tanacetum vulgare are chemotype‐dependent

open access: yesPlant Biology, EarlyView.
Common tansy varieties defend differently: some boost root chemicals against soil pests, while others release stronger leaf scents against aphids. Abstract Specialized metabolites such as terpenoids are known to mediate plant defence mechanisms. However, how terpenoid diversity governs inducible chemistry across organs remains poorly understood.

Restoration age, distance from reference ecosystems, and host plant feeding guilds shape the diversity of frugivorous butterflies in ecological restoration areas in the Atlantic Forest

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction The fragmentation of the Atlantic Forest has caused severe biodiversity loss. In Paraná State, more than 96% of the original vegetation, predominantly semideciduous seasonal forest, has been degraded. Ecological restoration is a key strategy to reverse this scenario, aiming to recover environmental conditions equivalent to the ...
