the present article deals with the inter specific competition and intra-specific competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. the behaviour of the system near the biologically feasible equilibria is thoroughly analyzed. boundedness and dissipativeness of the system are e...

sowing date and plant density are important factors in grain yield of cow pea. in order to study effect of sowing date and plant density on yield and yield components of cow pea, an experiment was conducted in research farm of ramin university of agricultural and natural resources in 2008. the experimental design was split plots in randomized complete design with four replications. the experime...

poplar trees are becoming extremely important as fast growing species due to the increasing need for wood and decreasing productivity of some lands in iran. the present study aimed to find the effect of canopy of poplar clones as one of the most important effective factors on soil properties compared to the distances inter-row trees. five poplar clones and species included: populus euramericana...

This work proposes a novel algorithm for performing robust feature-based stereo-matching, without the ordering constraint. The calculation of the disparity map is decomposed to a set of disjoint intra-row subproblems, each one having two objectives: the search for a high con"dence intra-row matching and the enforcement of "gural continuity at the inter-row level. A separate genetic algorithm (G...

Typically, low-pressure sprayers are used to uniformly apply pre- and post-emergent herbicides to control weeds in crop rows. An innovative machine for weed control in inter-row and intra-row areas, with a unique combination of inter-row cultivation tooling and intra-row band spraying for six rows and an electro-hydraulic side-shift frame controlled by a GPS system, was developed and evaluated....

purposes: the aim of this study was to evaluate the intra and inter-examiner reliability and reproducibility of linear measurements in cone-beam tomography (cbct) images taken by calibrated radiologists and periodontists. materials and methods: the alveolar ridge dimensions in selected cbct images were measured by two calibrated radiologists and two periodontists. intra and inter-examiner relia...

objectives: the main purpose of this research was to study and contribute to an accurate test of spastic limb. the intra, inter rater reliability of the test was examined. methods: the present study was carried out in two parts in the first part of the study, the modified ashworth scale with intermediate scores (asis) was studied. during the second part of the study the intra, inter rater relia...
