Sealing ability of materials used as protective cervical barrier in internal tooth bleaching [PDF]

open access: yes, 2017
The use of a protective cervical barrier (PCB) is very well established to perform a safe internal bleaching; however, there is still no consensus on which material has the best sealing ability. Objective: This in vitro study aimed to evaluate the apical

Modelling and simulation of acrylic bone cement injection and curing within the framework of vertebroplasty [PDF]

open access: yes, 2013
The minimal invasive procedure of vertebroplasty is a surgical technique to treat compression fractures of vertebral bodies. During the treatment, liquid bone cement gets injected into the affected vertebral body and therein cures to a solid. In order to investigate the treatment and the impact of injected bone cement, an integrated modelling and ...

Technical Measures, Environmental Protection, and Trade

open access: yesReview of International Economics, EarlyView.
ABSTRACT Technical regulations are increasingly numerous, complex, and often less transparent than traditional price‐based measures. Widely employed to achieve nontrade policy objectives, these measures are frequently adopted for environmental protection purposes. However, the trade effects of environmental measures remain underexplored. Using a unique

Comparative Environmental Impact Assessment of a Daily Electricity Restitution Operated by Advanced Adiabatic Compressed Air Energy Storage Systems (A‐CAES)

open access: yesEnergy Storage, Volume 7, Issue 4, June 2025.
ABSTRACT Renewable energy storage is essential to address the intermittent nature of renewable sources. Beyond widely used Li‐ion batteries and Pumped Hydro Energy Storage (PHES), Advanced Adiabatic Compressed Air Energy Storage (A‐CAES) offers promising potential, although it is not yet commercially available in Europe.

Fertilizer usage and cadmium in soils, crops and food [PDF]

open access: yesarXiv, 2018
Phosphate fertilizers were first implicated by Schroeder and Balassa in 1963 for increasing the Cd concentration in cultivated soils and crops. This suggestion has become a part of the accepted paradigm on soil toxicity. Consequently, stringent fertilizer control programs to monitor Cd have been launched. Attempts to link Cd toxicity and fertilizers to

Establishing detailed chemofacies of depositional environments in an epeiric seaway using high‐resolution (500 μm) micro X‐ray fluorescence core scanning data

open access: yesSedimentology, Volume 72, Issue 4, Page 1316-1342, June 2025.
ABSTRACT Establishing depositional environments in ancient mudstone successions from epeiric seas is difficult due to the lack of obvious lithological changes, leaving long, largely undifferentiated mudstone intervals that complicate their correlation to near‐shore environments.
