Acidification of musts in warm regions with tartaric acid and calcium sulfate at industrial scale [PDF]

open access: yes, 2015
Acidification of musts is necessary in warm areas where high temperatures during ripening accelerate breathing combustion of tartaric acid and, in particular, malic acid in the berries.

Effect of Crown Design, Cement Type and Margin Depth on the Removal of Cement Remnants Around Single Implant‐Supported Restorations. An In‐Vitro Study

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To assess the influence of crown design, cement type, and margin depth on the removal efficiency of residual cement around single implant‐supported restorations. Methods Twelve mandibular models with a missing first molar were fabricated and provided with single implant analogs (centrally/distally placed) and two different crown ...

Preparation and Characterization of Lime Activated Unfired Bricks Made with Industrial Wastes [PDF]

open access: yes, 2013
Utilization of fly ash can reduces the solid waste disposal problem and minimization of pollution also. Conventional production of bricks usually utilizes clay and shale as the source material and requires high temperature (900– 1000 °C) kiln firing ...

Biomechanical Analysis of 3D Printed and Thermoformed EVA Custom‐Made Mouthguard: Experimental and Finite Element Analyses

open access: yesDental Traumatology, EarlyView.
ABSTRACT Background/Objective 3D printed materials have been evaluated for fabricating mouthguards; however, little is known about their biomechanical performance in preventing dental trauma. This study aimed to compare two 3D printed polymers and three ethylene vinyl acetate (EVA) sheets used for mouthguard fabrication regarding their mechanical ...

Wall Compensation for Ultra Wideband Applications [PDF]

open access: yes, 2012
Due to their low frequency contents, ultra wideband (UWB) signals have the ability to penetrate walls and obstacles. As the signal propagates through these obstacles, it gets attenuated, slows down, and gets dispersed.

Noise Exposure in a Dental Teaching Hospital: Investigations and Recommendations for Dental Personnel

open access: yesEuropean Journal of Dental Education, EarlyView.
ABSTRACT Introduction Exposure to excessive noise is a highly preventable occupational risk, with irreversible side effects that may negatively impact an individual's quality of life, such as noise‐induced hearing loss and tinnitus. Dental personnel may be at particular risk due to their exposure to high levels of noise from dental equipment.

Modeling Assessment of Aquifer Contamination by Sulfate and Uranium in the Upper Arkansas River Corridor in Kansas

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Groundwater in the upper Arkansas River corridor has been contaminated by elevated concentrations of dissolved solids in Arkansas River water. Most of the dissolved solids originate from the soils and bedrock in eastern Colorado, where river water is diverted for irrigation and storage systems, and evapotranspiration significantly increases ...

Isotopy, micromorphology and composition of pedogenic gypsum in loess-palaeosol sequences in the Ebro Valley as a combined paleoenvironmental proxy

open access: yesGeoderma
The loess palaeosol sequences in the Ebro valley are associated with arid and semi-arid climates in the past, where the main pedogenic process is the mobilisation of carbonate and gypsum through the soil, resulting in secondary accumulations.
