Fate of nickel and calcium in seedlings of the hyperaccumulator Berkheya coddii during germination

Biologia Plantarum, 2015
Little is known about Ni storage in seeds of hyperaccumulating plants and its possible role in the first stages of plant development. The aim of this study was to determine Ni distribution in seeds and seedlings during germination and to test its role ...

Application of laser produced ion beams to nuclear analysis of materials

EPJ Web of Conferences, 2013
The ion beam driven nuclear analysis has been developed for many years by using various electrostatic accelerators. A proton micro-beam with the beam diameter of ∼1.5 μm at Takasaki Ion Acceleration for Advanced Radiation Application (TIARA), JAEA was ...

Zinc allocation to and within Arabidopsis halleri seeds: Different strategies of metal homeostasis in accessions under divergent selection pressure

Plant-Environment Interactions, 2020
Vegetative tissues of metal(loid)‐hyperaccumulating plants are widely used to study plant metal homeostasis and adaptation to metalliferous soils, but little is known about these mechanisms in their seeds.

EVALUATION OF THIN SECTION STANDARDS FOR LOCAL ANALYSIS OF LIGHT ELEMENTS BY MICRO-PIXE ANALYSIS

, 2011
For quantitative measurements of light elements by micro-PIXE (particle-induced X-ray emission) analysis, suitable external standards have been expected. In this paper thin sections of polyvinyl alcohol solution containing phosphorus ( P ) and potassium

The Fiery Eyes of a Maenad: Origin Determination of Faceted Garnet Eye Inlays in a Roman Bronze Bust From Southern Tyrol

Archaeometry, EarlyView.
ABSTRACT In 1837, the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria, purchased a Roman bronze statue of a maenad from the 2nd century ce with red garnets as facetted eye inlays found near Brixen, Southern Tyrol. These garnets were investigated using optical microscopy, a portable hand‐held and a stationary micro‐X‐ray fluorescence device, as

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.
