RISPhysiological indices of weed species effects at different density on corn (Zea mays L.) growth
Crop density is one of the usage tools in sustainable agriculture to carry out integrated weed management. This study was conducted in research field of Ferdowsi University of Mashhad, Iran. Four levels of corn densities (5, 6, 7 and 9 plant /m2...
First principle study of Lithium impurity effect on energy gap of trans-polyacetylene chain
In this work we have calculated the electronic states of the trans-polyacetylene (t-PA) molecule within the
framework of Density Functional Theory (DFT). For this purpose we have used SIESTA code based on the DFT
within the Local...

Some approximations of the logistic distribution with application to the covariance matrix of logistic regression
wavelet based estimators for density
the wavelet estimator for density and regression functions are introduces and the rate of convergence derived....
Intercropping soybean cultivars under different plant densities

Saffron corm: Science and Technology
of the corm. The number of buds is strongly associated with corm size and hence the number of flower produced per corm. Therefore corm size is crucial to flower production and economic yield. Second factor associated with corm and yield is the density...
