Large isoparametric macroelements with closed-form cardinal global shape functions under the label ‘Coons-patch macroelements’ (CPM) have been previously proposed and used in conjunction with the finite element method and the boundary element method. This paper continues the research on the performance of CPM in conjunction with the collocation method. In contrast to the previous CPM that was b...

Linear-constant velocity-pressure elements are enriched with residual-free macro bubbles. Static condensation prompts a stabilized method for this element, where mesh-dependent jumps of the normal stress are added across internal edges of the underlying macroelements. This procedure renders the SIMPLEST element stable.

We construct trivariate macro-elements of class Cr for any r ≥ 1 over the Alfeld refinement of any tetrahedral partition in R3. In our construction, the degree of polynomials used for these macro-elements is the lowest possible. We also give the dimension formula for the subspace of consisting of these macroelements.

The biological value of fodder is estimated on the basis of its content of particular macroelements (N, P, K, Ca, Mg). Concentration of these components in fodder depends on many factors, mainly on the properties of soil, type of land use and growth phase of crops. The aim of this paper was to estimate the effect of soil properties, land use and species composition of a sward mixture on the con...

abstract common bean (phaseolus vulgaris l.) is one of the most important crops in lorestan province with about 23000 ha. in this area, two spotted spider mite (tssm) tetranychus urticae koch is the key pest of this crop. to study the effect of macroelements (npk) fertilizers, on controlling tssm and their effect on some agronomic characters of derakhshan bean cultivar, two same trails (1. trea...

We develop a conservative cut finite element method for an elliptic coupled bulk-interface problem. The is based on discontinuous Galerkin framework where stabilization added in such way that we retain conservation macroelements containing one with large intersection the domain and possibly number of elements small intersections. derive error estimates present confirming numerical results.

The paper presents chemical and nutritional information on the underutilised seeds of M. chrysanthum. Chemical analyses show that the seeds are not rich in lipids and hence have a low energy value. The seeds were found to be rich in some essential amino acids (especially lysine), macroelements (Na, K, Mg) and ascorbic acid. The antinutrient levels of tannin, phytic acid and hydrogen cyanide wer...
