the persian walnut (juglans regia l.) is one of the most important horticultural crops grown in iran. this research was conducted to determine the variation in walnut germplasm grown in the arak region of iran during the 2007-2008 growing seasons. all of the selected genotypes originated from seed, and their phenological and pomological characteristics were evaluated. results indicated that the...

Seed dispersal is a key ecological process in tropical forests, with effects on various levels ranging from plant reproductive success to the carbon storage potential of tropical rainforests. On a local and landscape scale, spatial patterns of seed dispersal create the template for the recruitment process and thus influence the population dynamics of plant species. The strength of this influenc...

The ability of Multi-Layer Perceptron (MLP) and Neuro-Fuzzy neural networks to classify corn seed varieties based on mixed morphological and color Features has been evaluated that would be helpful for automation of corn handling. This research was done in Islamic Azad University, Shahr-e-Rey Branch, during 2011 on 5 main corn varieties were grown in different environments of Iran. A total of 12...

Maize is one of the most important crops worldwide and is strongly dependent on arbuscular mycorrhiza (AM) fungi, organisms that form a mutualistic association with land plants. In maize, AM symbiosis enhances spike dry weight, spike length, spike circumference, and the dry weight and dimensions of the grain. Notwithstanding its ubiquitous nature, the detailed relationship between AM fungal col...

Computers are by their definition predictable. The problem of obtaining good-quality random numbers is well known. There is a great need for entropy in the running kernel, as well as in user-space. The kernel needs to randomise TCP sequences, seed keys for IPSec, randomise PIDs, and so on. Starvation of these random numbers is a critical problem. Users need random keys, random filenames, nondet...

Apricot is a fruit demanded and consumed in variety of ways by consumers. has kernel inside it. Due to limited knowledge bioactive compounds, apricot kernels were predicted as food waste the past, they had no economic value. Awareness nutrition compounds increased recently, idea emerged that healthy its fruit, therefore science research focused on examining properties kernels. In this study, sw...
