The purpose of this study was to evaluate the profitability of hatchery litter recycling into poultry feedstuff supplement. The data were collected in 2011 in 4 provinces, by direct interviewing of all hatcheries which used the hatchery litter drying machine. Net Present Value (NPV), Benefit-Cost Ratio (BCR), and Internal Rate of Return (IRR) methods were applied for this analysis. In the studi...

Crop canopies and residues have been shown to intercept a significant amount of rainfall. However, rainfall or irrigation interception by crops and residues has often been overlooked in hydrologic modelling. Crop canopy interception is controlled by canopy density and rainfall intensity and duration. Crop residue interception is a function of crop residue type, residue density and cover, and ra...

Litter, LS, is the organic material in which locates top A soil horizon, playing key ecological roles forests. Models, contrast to common allocation factors, must be used LS assessments as they are currently absent scientific literature. Its evaluation assess mass, input and flux of several bio-geo-chemicals, rainfall interception one component local hydrology, wildfire regimes, among others, h...

While graphs are normally defined in terms of the 2-place relation of adjacency, we take the 3-place relation of interception as the basic primitive of the definition. The paper views graphs as an economic scheme for encoding interception relations, and establishes an axiomatic characterization of relations that lend themselves to representation in terms of graph interception, thus providing a ...

Developing applications that support evolution in a seamless way is not an easy task; in an early design stage, some concepts may be confused or some potential functionality not foreseen, resulting in bad separations of concerns. In this kind of designs, future changes may imply huge modifications if a highquality object-oriented model is the desired product. In theory, object oriented programm...

This study was designed to define the characteristics of eye-hand coordination in a task requiring the interception of a moving target. It also assessed the extent to which the motion of the target was predicted and the strategies subjects used to determine when to initiate target interception. Target trajectories were constructed from sums of sines in the horizontal and vertical dimensions. Su...

in order to study of the radiation interception and red to far red light ratio variations in sunflower hybrids under drought stress, nine sunflower hybrids in three separate experiments were compared as randomized complete block designs with three replications at the research station of seed and plant improvement institute in karaj in 2006. first experiment (control) was irrigated based on 60 m...
