Effects of high‐speed sintering on the translucency and color of dental zirconia with different shades and yttria contents

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated the effects of high‐speed sintering on the translucency and color of various yttria‐stabilized zirconia (YSZ) compositions and identified factors influencing these properties to improve clinical predictability. Materials and Methods A total of 144 disc‐shaped specimens fabricated from 3YSZ, 4YSZ, and 5YSZ pucks in ...

Estimating past fluid pH and evaporative conditions in Gale crater using terrestrial analog samples from Death Valley, CA

Meteoritics &Planetary Science, EarlyView.
Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...

Genetic Analysis of East African Sorghum Genotypes for Yield Components and Iron and Zinc Composition

Plant Breeding, EarlyView.
ABSTRACT Sorghum [Sorghum bicolor (L.) Moench] is a vital cereal crop in dry regions worldwide. However, in sub‐Saharan Africa (SSA), grain yields from currently grown varieties remain low (< 1 ton/ha) and exhibit variable nutrient composition. Therefore, the objective of this study was to undertake a genetic analysis of selected East African‐adapted ...

Physical and chemical characterization of recycled glass sand for environmental restoration

Restoration Ecology, EarlyView.
Abstract Introduction We rely on coastal resources for food, water, and energy. However, over 75% of U.S. coastlines are eroding. Concurrently, the U.S. recycles less glass than other developed countries, landfilling hundreds of millions of tons every year.

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...
