Does attachment removal damage enamel? Influence of adhesive, resin, and bur on surface integrity

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 3, June 2026.
Abstract To evaluate the combination of composites, adhesive systems, and burs considering artificial accelerated aging (AAA), influence enamel roughness and morphology after attachment removal. One hundred ninety‐two bovine enamel specimens were divided according to composite type (Transbond XT, flowable, bulk‐fill flowable), adhesive system (Single ...

Wage Differentials, Firm Investment, and Stock Returns

open access: yesInternational Review of Finance, Volume 26, Issue 2, June 2026.
ABSTRACT This study investigates the effects of labor costs on firms' capital investments and stock returns. I estimate wage premia across US industries and show that the negative investment‐return relation implied by q$$ q $$‐theory is steeper for firms paying high wage premia than for firms paying low wage premia.

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.
