Mineral physics dictate the appearance of rocks and soils across the electromagnetic spectrum. In the Visible/Near-Infrared (VNIR) and Short Wave Infrared (SWIR), many materials absorb radiation at specific wavelengths, allowing their identification by the position and character of absorption features. Electronic processes at wavelengths less ~1.0 micrometers allow (in addition to others) ident...

The analysis of minerals on Mars may yield some clues to the geologic processes that formed its current surfaces. Two main theories exist to explain the dichotomy in terrains on Mars, a large impact to the Northern hemisphere, or the previous existence of an ocean in the Northern hemisphere. Impact craters in the Northern hemisphere unearth buried compounds, and may show a difference in mineral...

In this study, the bone structures, nanomechanical properties and fracture behaviors in different groups of female C57BL/6 mice (control, sham operated, ovariectomized, casein supplemented, and fermented milk supplemented) were examined by micro-computed tomography, scanning and transmission electron microscopy, and nanoindentation. The control and sham operated mice showed dense bone structure...

Roasted and non roasted full fat or partially defatted flaxseed flours (Linum Usitatissimum) were evaluated for their proximate composition, mineral profile and functional properties. Significant increase in the crude protein, crude fiber, ash and mineral contents in the partially defatted flaxseed flours (both roasted and non-roasted) was observed. Partial defattening improved the foam capacit...

The concept of bone quality describes the sets of the characteristics of the osseous tissue that influence bone strength. The aim was to explore the influence of anthropometric parameters and age on the parameters of the bone architecture and bone mineral properties in the lumbar vertebral bone of men and women. Vertebral bone samples underwent bone histomorphometry, bone densitometry and atomi...

Selenium is an essential mineral element to humans and animals because it is an important component of selenoproteins that are important for functioning of the metabolism. Because of poor soil conditions in various regions of the world, the enrichment of edible plants with selenium via the biofortification strategy has been implemented. However, selenium in the context of plant mineral nutritio...

The reflectance model developed by Kubelka and Munk was evaluated for agreement in color prediction of thick pigmented samples and for linearity of optical absorption and scattering coefficients with concentration of colorant in maxillofacial elastomer. The colorants tested were generic opacifiers, dry mineral earth pigments, and fibrous colorants. Significant linear relationships were commonly...

Mass specific optical absorption coefficients of mineral dust components measured by a multi wavelength photoacoustic spectrometer N. Utry, T. Ajtai, M. Pintér, E. Tombácz, E. Illés, Z.

On the basis of atomic absorption spectrophotometry rat teeth and mandible magnesium levels in experimental postmenopausal osteoporosis and after administration of 17 βestradiol were measured. The results showed that estrogen deficiency after ovariectomy decreased the magnesium content in rat teeth and mandible and administration of 17β-estradiol influences in good way the mineral components of...
