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.

Declining habitat directive butterflies within a major stronghold: Challenges for conservation Rückläufige Tagfalter der FFH‐Richtlinie in einer bedeutenden Hochburg: Herausforderungen für den Naturschutz

open access: yesInsect Conservation and Diversity, EarlyView.
Myrmecophilous Phengaris nausithous and P. teleius are highly specialized grassland butterflies and flagship species for European nature conservation, but they exhibit ongoing population declines. We show strong declines for both species in the Westerwald mountain range, western Germany, since 1994, driven by inappropriate timing of mowing, grassland ...

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

open access: yesJournal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.

Exploring the Association Between Complaints of Sensory Hypersensitivity and Sleep Disturbances After Acquired Brain Injury: A Cross‐Sectional Study

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep disturbances are prevalent after acquired brain injury and negatively affect quality of life. Sensory hypersensitivity may cause or exacerbate sleep disturbances, yet evidence on this relationship after acquired brain injury is lacking. The aim of this study was to investigate the hypothesised positive relationship between the severity ...

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...
