Recent years have seen an explosion in the number of studies that explore the collective dynamics of biomo-lecular systems using coarse-grained (CG) models along with methods based on principal component analysis (PCA). Among them, elastic network models (ENMs) and normal mode analyses (NMAs) have found wide use in several applications. Recent studies are now providing evidence for the usefulne...

information on nitrate in groundwater resources requires periodic measurements are accurate. despite the measure in some areas due to sensitive social and health community are not reported. therefore, be informed of the status of each area of water quality, modeling is essential. the purpose of this study was the application of artificial neural network method for estimating nitrate and compare...

Today, it is known that formal education models alone are not sufficient for the complexity of design education. Thus, these should be supported by informal methods. In contemporary architectural education, structure various tools such as competitions, workshops, and panels. However, although seen two different models, possible to draw a clear boundary between Because can said today's contains ...

up to now, interactions between method and amount of nitrogen fertilizers application on plant density and variety of wheat under sprinkler irrigation systems have not been studied. thus, this research was conducted during two years in esfehan region with split factorial design. the treatments of this experiment were: three fertilizers application methods (conventional manual application at the...

this research was conducted on determination of better planting distance and better amount of nitrogen and phosphorus for hybrid rice (bahar 1). planting distance were used in this experiment, include 30×15, 30×20 and 30×25 cm as main factor. and also nitrogen fertilizer was used, include four levels, 65, 95, 125 and 155 k/ha and phosphorus fertilizer used include tow levels, 50 and 100 k/ha as...
