Sequence of activities has evident and objective aspects in the people living environment that depend on subjective and meaningful aspects in their culture and lifestyle. The sequence of activities with two forms of "spatial and temporal", are ways of separation or aggregation of activities in different cultures dwelling, which lie at the origin of the formation of behaviour settings. The theor...
introduction: the accuracy of analyzing functional mri (fmri) data is usually decreases in the presence of noise and artifact sources. a common solution in for analyzing fmri data having high noise is to use suitable preprocessing methods with the aim of data denoising. some effects of preprocessing methods on the parametric methods such as general linear model (glm) have previously been evalua...
Fluoride is found in all water resources at different concentrations and drinking water is the major source of fluoride exposure. Thus, because of the adverse effect of fluoride in low and high concentrations, the evaluation of its content in drinking water is necessary. In the present study, the temporal variations and spatial distribution of fluoride concentrations in the drinking water of vi...
Copepods are the main zooplankton assemblages in most tropical and semi-tropical estuaries. In this research, copepod population dynamics were investigated in Helleh River estuary, Persian Gulf during four seasons beginning from summer 2011 to spring 2012. Samples were taken using plankton net with mesh size of 140 µm and vertical towing from 5 fixed-stations in mid-season. Results showed that...
"> The present study described the diversity of wheat and barley varieties andlandraces available in farmer’s fields in Syria using different indicators. Analysisof spatial and temporal diversity and coefficient of parentage along withmeasurements of agronomic and morphological traits were employed to explain thediversity of wheat and barley varieties or landraces grown by farmers in Syria.Farm...
Spatial-temporal modeling of air pollutants, ground-level ozone concentrations in particular, has attracted recent attention because by using spatial-temporal modeling, can analyze, interpolate or predict ozone levels at any location. In this paper we consider daily averages of troposphere ozone over Tehran city. For eliminating the trend of data, a dynamic linear model is used, then some featu...
To deepen our understanding of object recognition, it is critical to understand the nature of transformations that occur in intermediate stages of processing in the ventral visual pathway, such as area V4. Neurons in V4 are selective to local features of global shape, such as extended contours. Previously, we found that V4 neurons selective for curved elements exhibit a high degree of spatial v...
River Ganga is one of the prime sacred National Rivers of India, closely associated with economic, social, and cultural heritage of Indian people. Recently, it has been subjected to immense degradation and pollution as a result of receiving huge amounts of domestic and industrial wastewater as well as religious ritual activities and surface runoff. The present study attempts to study spatial an...
