Computer Graphics (CG) and Virtual Reality (VR) technologies have rapidly improved in recent years. It enabled us to develop some useful systems such as air hockey, catch ball, tennis and horseback riding for sports field, surgical simulations and support systems for medical field, calligraphy and flower arrangement for educational field. The good training systems have force feedback for users ...

in iran, more than 90% of raw materials including oils and oil seeds are provided through import. camelina sativa l. as an oilseed crop, belongs to brassicaceae family, has been shown in several experiments that need very little water and resistant to chilling injury than other plant oils, especially canola. this experiment was conducted at research station of campus of agriculture and natural ...

to study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and oil percentage of goldasht spring safflower cultivar, an experiment was carried out in 2012 in the agricultural research farm station of islamic azad university, roudehen branch as split plot in a completely randomized blocks design with three replications. in ...

in order to comparison the foliar application of biological, biostimulator and chemical fertilizers on growth characteristics and yield of saffron, a factorial experiment was conducted in a completely randomized block design with four replication in 3- year field of saffron in dargaz, khorasan razavi province from 2010 to 2011. the first factor had 5 levels included biostimulator fertilizer bio...

The influence of scoring during the flower induction phase was investigated. Pear trees, Pyrus communis L. cv. Doyenne du Comice, Forelle and Rosemarie were used in the study, conducted in the Western Cape, South Africa. The yield of ‘Doyenne du Comice’ increased by 38% in scored trees compared to the control. The increase in yield was due to 50% more fruits on the scored trees than on the cont...

Larger floral displays increase pollinator visitation as well as among-flower self-pollination (geitonogamy) in self-compatible species. Dichogamy (temporal separation of gender expression) can limit geitonogamy and increase outcrossing but this depends on pollinator behavior within inflorescences. Declining nectar volume from lower to upper flowers is a hypothesized adaptation to increase outc...

This research had conducted to investigate light intensity effects on the lucky bamboo growth in Islamic Azad University, Abhar Branch. The experiment arranged as a complete randomized block design with five treatments (0.75, 1.14, 1.89, 2.29 and 4.09 mmol m-2 s-1) in ten replications. Results showed that 1.89 mmol m-2 s-1 had significant differences than other treatments. The higher level of r...
