The selection efficiency of the most desirable safflower genotypes can be improved by incorporating the graphical methods and statistical analysis. This experiment was carried out to determine grain yield stability of safflower genotypes using the graphical and statistical methods. Twenty safflower genotypes were evaluated in Chachsaran, Choram, Behbehan and Dehdasht using randomized complete b...

Asian slow lorises are found in zoos and rescue centres worldwide with Nycticebus pygmaeus, the pygmy slow loris, boasting the largest population in captivity. Diet are reportedly high in fruit and concentrates and low in insects and exudates. Wild feeding studies place insects, nectar, and gums as the most important diet components. Captive populations also show high incidences of health affli...

Purpose: The aim of this study was to investigate the role of individual and collective components on the formation of social trust in high school students. Methodology: The present study was applied in terms of purpose and mixed in terms of implementation method (qualitative and quantitative). The research population was in the qualitative part of experts, experts and specialists in the field...

Computation of high frequency solutions to wave equations is important in many applications, and notoriously difficult in resolving wave oscillations. Gaussian beams are asymptotically valid high frequency solutions concentrated on a single curve through the physical domain, and superposition of Gaussian beams provides a powerful tool for generating more general high frequency solutions to PDEs...

This paper describes a hybrid approach for unsupervised and unrestricted relation discovery between entities using output from linguistic analysis and semantic typing information from a knowledge base. We use Factz (encoded as subject, predicate and object triples) produced by Powerset as a result of linguistic analysis. A particular relation may be expressed in a variety of ways in text and he...

The natural forest and range stands of Zanjan province are located in mountainous areas. Inventorying and mapping of natural forest and range stands in mountainous areas are difficult and costly. Satellite data are suitable for this purpose. The Landsat ETM+ image data of 2002 are used for classification and mapping of natural forest stands in Zanjan province. For the purpose of data reduction ...

2014 This is the first part of a structural study of the modulation in thiourea. The modulation is described by a normal mode Qq of 03C44 symmetry along with harmonic modes Q2q, Q3q, ... Corresponding displacements are derived in view of structure refinement. In commensurate phases, these give access to the space group; in incommensurate phases, to the supersymmetry. The superspace approach to ...

This paper deals with a new framework in analyzing the formal mathematical correspondence between quantum mechanics and time-frequency representations of a signal. It is also shown that joint time-frequency distributions have a close link with Heisenberg uncertainty relations if the observables are taken as fuzzy entities. This result contradicts the arguments of Cohen [IEEE Proc. 77(7):941 (19...
