Background. Interest in the study of microwave metamaterials is associated with possibility using them to achieve required frequency and polarization selective properties interaction electromagnetic radiation, which can’t be obtained for structures based on homogeneous media. Aim. The mathematical model a chiral metamaterial periodic matrix arbitrarily oriented conducting thin-wire cylindrical ...

natural organic wastes contain considerable amounts of nutritional elements. the availability and uptake of nutrient elements in soil) especially in alkali and calcareous soils) increase due to high content of organic matter, and reduce the micro-elements deficiencies. organic wastes have pathogenic contaminations that come from waste type and transmitted by microorganisms such as bacteria, fun...

Geochemical anomalies are geochemical features different from what is considered normal. They can be the result of: 1. unusual or uncommon processes concentrating particular elements (e.g. an ore-forming process, weathering and element dispersion from an unusual element concentration such as an orebody); 2. element accumulation or concentration by common processes acting over long periods (e.g....

the chemical extraction of twenty-nine elements in a washing aggregate sludge, a clay-richsediment, a sewage sludge, the mixtures of these materials and the artificial lightweight aggregates (lwas)manufactured with them was determined by applying the optimized european community bureau of reference sequential extraction procedure in order to establish the effect of the thermal treatment on the ...

INTRODUCTION In any field of investigations new ideas in combination with newly developed equipment can provide advance results. In view of arising interest to cold nuclear fusion (CNF) [1] and searches for consequences of its occurrence the study of the interaction of hydrogen with metals has coincided with the wide spread of the micro-probe X-ray spectrum analysis. This analysis is performed ...
