<p>Plasticine is an artificial material made from solids such as gypsum, lime, mixed with petroleum jelly or micro wax and acid fat. The properties of plasticine are likely similar to natural clay influenced by oil content. information about mechanical still very rare, the study on it riquired must be conducted intensively. preliminary laboratory has been understand behaviour plasticines....

This paper describes an MPM formulation using linear quadrilateral elements suitable for soil-structure-interaction problems. The volumetric locking and stress-oscillations are mitigated a reduced integration technique the Gauss scheme, respectively. can be used with both structured unstructured computational meshes. In addition, improved calculation scheme is proposed to obtain accurate contac...

Agriculture land shows soil compaction problems due to long-term agricultural cultivation activities. Soil indicator can be seen from the value of penetration resistance at different depths (0 - 60 cm). This research aimed determine coffee plantation ages with and analyze relationship between physical characteristics productivity. The survey activities include observation minipits, measuring 0-...

The Red Delicious has for many years represented the ideal apple and has been a symbol of consistent crispness and delicious flavor. However, changes in the way Red Delicious varieties are bred, distributed, and sold threaten to displace the Red Delicious apple from its central role in the industry. One important component in this shift is the trend in the last decade of breeding Red Delicious ...
