Macro-elements of smoothness Cr are constructed on PowellSabin-12 splits of a triangle for all r ≥ 0. These new elements complement those recently constructed on Powell-Sabin-6 splits and can be used to construct convenient superspline spaces with stable local bases and full approximation power that can be applied to the solution of boundary-value problems and for interpolation of Hermite data.

INTRODUCTION The objective was to assess the quality of pregnant women's diet in Poland concerning macro-elements and to analyze reasons for low or high quality diets. MATERIAL AND METHODS Five hundred and twelve pregnant women in their 20(th) to 30(th) week of pregnancy took part in the research conducted by means of a 7-day observation of diet. Consumed products were analyzed by means of DI...

Water is one of the most stable and abundant complexes on nature that can be polluted with natural and human factors. Therefore, it is necessary to ensure a timely warning for possible accumulation of polluting metal in natural waters in order to protect public health. One of the economic and rapid methods for elements removal is displacement of metals by biosorption. The purpose of this study ...

A variant of the classical C Powell-Sabin-12 macro-element is defined that has the same approximation power, but has fewer degrees of freedom and only requires vertex data. The same idea is then applied to a related C trivariate macro-element. §

abstract in order to investigate correlation between the rate (amount) of micro and macro elements and protein percentage in pistachio kernels of six cultivar including: akbari, abbasali, kaleh gouchi, ahmadaghaie, ouhadi and khanjari with aspergillus flavus growth and aflatoxin b1 production, the amount of micro and macro elements were measured using atomic absorption, micro-kjeldhal digestion...

The present study provides the dietary intakes of macro elements (Ca, Mg, Na, K, P) and trace elements (Fe, Zn, Cu, Se) from the Italian total diet. The contribution of the most representative food groups of the total diet (cereals and cereal products, vegetables, fruit, milk and dairy products, meat and meat products, fish) to the daily intakes of these nutrients was also evaluated. The Italia...

Reductionism assumes that causation in the physical world occurs at the micro level, excluding the emergence of macro-level causation. We challenge this reductionist assumption by demonstrating that, once causal power is properly defined and measured, it is possible for a macro level to “beat” the micro level. Here, this was done through a principled, well-defined measure of intrinsic cause-eff...
