This paper presents a new Modified Cam Clay (MCC) type yield function, that is designed for robust and efficient use with implicit stress integration algorithms. The proposed function attains non-elliptical (e.g. tear bullet) shapes, as well the typical elliptical shape of MCC model. Like MCC, unlike most other functions shapes available in literature, it non-singular unique throughout space. e...

This study aimed to evaluate the grain yield of soybean cultivars as a function different sowing seasons and soil types, in Western region São Paulo state. Two experiments were performed district Gardênia, municipality Rancharia-SP two types (Red Argisol with medium sandy texture Red Nitosol very clayey texture). For both studies, randomized block design 5 x 2 factorial scheme arranged strips w...

the objective of this study was to estimates the genetic and environmental components for the lactation curve parameters, milk yield, age at first calving (afc), calving interval (ci) and somatic cell count (scc) in iranian holstein cows. the dataset consisted of 210625 test day records from 25883 cows with milk yield in the first parity recorded from july 2002 to september 2007 in a total of 9...

Much effort has been devoted to the synthesis of gold nanoparticles with different shapes, including the zero-dimensional nanospheres, one dimensional nanorods, and two-dimensional nanoplates. Compared to zero or one dimensional nanostructures, the synthesis of two-dimensional nanostructures in high yield has always been more involved, often requiring complex and timeconsuming steps such as mor...

This work presents information on the patterns of yield determination by yield components as a function of the level of management of the crop. The data used for the analyses were obtained from 8 field experiments located across Poland in 2009 and 2010. 25 winter wheat cultivars were evaluated at two management levels, i.e., at a low input of nitrogen fertilisation and pesticides and at a h...

The yield function is very important in establishing the plastic constitutive relation and analyzing the plastic deformation. Hence this article derives the yield function on isotropic metals included one to six-order plastic tensor, expanded of the general yield function in its Taylor. As well, the plastic tensors are analyzed by traceless, totally symmetric and objectivity in this article. An...
