The experiment included three factors, fir...

Let G be a simple undirected graph with non-negative edge weights. In this paper we consider the following combinatorial optimization problem : Find, in G, a minimum weight spanning tree having diameter at most D. This problem is trivial for D :S 3 and NP-complete for D :: 4. In this paper we develop and implement a number of Branch and Bound algorithms for this problem. Computational results, ...

the effects of sodium chloride (nacl) salinity (control; canal water with 0.4 ds m-1), 2.5 dsm-1, 5.0 ds m-1, 7.5 ds m-1 and 10.0 ds m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (rosa hybrida l.) cultivars viz. ‘kardinal’, ‘angelique’ and ‘gold medal’ were studied to achieve better management, quality product...

any defects in street trees may cause injuries to human, vehicles and buildings. this research was investigated in the babol city, mazandaran province, in the northern state of iran.used the perfect inventory methods and measured the diameter at breathe height (dbh), height and hazardous criteria (dead woods, cracks or seams, decay, wound or cankers, root problems, weak branch unions and skew f...

The direction and speed of escape locomotion can affect the ability of an animal to evade a predator, and variation in habitat structure often affects speed. Consequently, the escape paths chosen by animals may affect their performance and subsequent survival. Arboreal locomotion is well suited for gaining insight into the choice of escape routes because of the discrete paths formed by branches...

The effect of tree age, size and competition on above ground growth allocation was studied with 69 Pinus sylvestris trees. Competition was described by tree-level indicators (needle density, crown ratio and height-diameter ratio). The stem, branch and needle growth were determined by stem and branch radial increments and tree level biomass analysis. Combined growth of compartments was strongly ...

The location of the opening of the zygomaticotemporal branch (ZTb) of the zygomatic nerve inside the orbit (ZTFIN) has significant surgical implications. This study was conducted to locate the ZTFIN and investigate the variations of the ZTb inside the orbit. A total of 20 sides from 10 fresh frozen cadaveric Caucasian heads were used in this study. The vertical distance between the inferior mar...

The architecture of spray cut chrysanthemum is crucial for the quality and quantity flower production. However, mechanism underlying plant still needs to be clarified. In this study, we measured nine architecture-related traits 195 varieties during a two-year period. results showed that number upper primary branches, lateral buds branch length widely varied. Additionally, height had significant...
