Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook (Centropomus parallelus) in the South Atlantic

Fisheries Management and Ecology, EarlyView.
ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicators from recreational fishing championships and artisanal landings along the

Application of Baicalein Solution as a Novel Antioxidant After Bleaching: Analysis of Its Effects on Immediate Color Stability and the Reestablishment of Bond Strength in Bleached Enamel

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the antioxidant capacity of the baicalein solution (BA), as well as its effect when applied for different times to the surface of bleached dental enamel, considering immediate color stability and bond strength. Materials and Methods Bovine enamel/dentin specimens (4 × 4 × 3 mm) were randomly divided into five groups (n ...

Incorporation of Calcium Polyphosphate Sub‐Microparticles in Commercial Toothpastes and Their Effects on Dental Enamel

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Dental bleaching with 35% hydrogen peroxide (HP) can cause deleterious effects on the mineral content of enamel. In this regard, remineralizing submicroparticles of calcium polyphosphate (CaPP) have been investigated for their ability to deposit calcium ions into enamel's hydroxyapatite.

Correlative microstructural analysis of a weathered nantan meteorite fragment

Journal of Microscopy, EarlyView.
Abstract The weathering of iron‐rich phases within meteorites is a multi‐stage process that significantly alters the microstructure and chemical composition based both on the environmental condition at the location of landing and the exposure time since the fall.

Assessing the analytical capabilities of handheld laser‐induced breakdown spectroscopy (hLIBS) on corroded iron objects of possible meteoritic origin

Meteoritics &Planetary Science, EarlyView.
Abstract Despite meteorites having been recognized as the source of iron in some ancient iron artifacts, few archeological irons have been analyzed so far, as invasive methods are precluded. In this work, four iron knives and one axe collected near Guelmime and Imilchil (Morocco) were investigated by advanced analytical techniques, including handheld ...

Thermal history, collisional history, and structure of the CK‐chondrite parent body

Meteoritics &Planetary Science, EarlyView.
Abstract Major chondrite groups (H, L, LL, R, EH, EL, CK) with some members of petrologic type 5 and 6 also have some members of types 3 and 4; they do not have members of type 1 or 2. Their parent bodies had onion‐shell structures and were internally heated by the decay of 26Al.
