By comparing the behavior of three Acromyrmex (Hymenoptera, Formicidae) species during foraging on artificial trails of different lengths, we observed the occurrence of task partitioning and its relation to the food distance ...

Erva-mate (Ilex paraguariensis) has an economical and environmental importance to the southern area of Brazil. However, there is no enough technologies of vegetative propagation, which are important to improve yield and ...

Introduction. Pitaya (Hylocereus undatus) is an exotic fruit species little known in Brazil and which needs basic studies about plant nutrition, propagation and physiology. Emphasizing the co-existence of juvenile and adult ...

The aim of this work was to verify the cuttings rooting potential of Sebastiana schottiana as mechanism of vegetative propagation. Cuttings were collected next to the edges of Soturno River, Faxinal de Soturno County, ...

Choosing the best season collection of cuttings is essential to have success with propagation, due mainly to carbohydrate content, since is a source of energy for roots and shoots development. In literature, there are no ...

In mechanized harvesting of wood operations, in a cut-to-length system, occupational noise is emitted by self-propelled forest machines, which compromises the safety and health of operators. Therefore, the occupational ...

This paper deals with the classical one-dimensional integer cutting stock problem, which consists of cutting a set of available stock lengths in order to produce smaller ordered items. This process is carried out in order ...
