Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

Screens, Teens, and Sleep: Is the Impact of Nighttime Screen Use on Sleep Driven by Physiological Arousal?

Journal of Sleep Research, EarlyView.
ABSTRACT Few studies have objectively measured both screens and sleep in real‐world settings. This study uses repeated measures to assess heart rate during evening screen use, providing new insights into how these behaviours relate to adolescent sleep. Screen use was recorded using wearable cameras over four nights in 70 youth (37% indigenous Māori, 42%

Temperature Acclimation of Chlorophyll Fluorescence and Carboxylation Capacity From Near‐Instantaneous to Weekly Time Scales

Plant, Cell &Environment, EarlyView.
ABSTRACT We studied near‐instantaneous temperature responses of light‐saturated photosynthesis (Asat) and the operating efficiency of photosystem II (ΦPSII) in relation to acclimation of photosynthetic biochemistry to temperature at the timescale of 1–8 days. We grew two closely related Brassica oleracea L.

Synthesis of New Hyperbranched Phosphorus-Containing Polyesters Starting from Boltorn H20

Proceedings, 2019
Upon gentle treatment with SOCl2, hyperbranched polyester Boltorn H20 afforded a mixture of terminal polychlorides. The latter react with an excess of triphenylphosphine in boiling toluene or with pyridine to give a mixture of polyesters with terminal ...

Evolution of Crematogaster sordidula (Hymenoptera, Formicidae) Ants in the Mediterranean Region During Plio‐Pleistocene Climatic Changes

Zoologica Scripta, EarlyView.
ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

The Crystal Structure of the Complex [Y(H20)s(N03)2] [Y(H20)2(N03)4]

Croatica Chemica Acta, 1984
The title compound was prepared by thermal d'ecomposition of crystals of Y (H20)4(N03)s · 2H20. The structure was solved by. Patterson and Fourier methods and isotropically refined to R=0.12. The unit cell is orthorhombic; the space group is C2221 The crystal contains two crystallographically and chemically different complex ions, with yttrium atoms as

Molecular Evidence for the Placement of Microcerberidae (Crustacea: Isopoda) Within the Suborder Asellota and Invalidity of the Suborder Microcerberidea

Zoologica Scripta, EarlyView.
ABSTRACT Since their discovery, the question of the phylogenetic position of Microcerberidae within Isopoda has been widely debated. Initially perceived as close relatives of the Anthuridae, the debate has shifted towards considering them either as a sister group of Asellota or positioned within the Asellota in their own right.
