so far a number of works on the heat flux anomalies of the earth surface based on the satellite images and underground water as seismic precursors have been carried out. in this paper the soil temperature data at 1m depth (deep enough to filter temperature variation due to high frequency meteorological forcings) has been considered to see if there are connections between earthquakes in bam and ...

the variability of temperature and precipitation is regarded as one of the main characteristics of the climate.precipitation and its results, especially results such as droughts, vary on different temporal and spatial scales. thepurpose of this paper is to determine the frequency of the inter-annual variability of the driest month in north-westiran. in order to obtain the best results, we used ...

abstract in this study we have used the monthly data resulted from the calculation of temperature and precipitation for a 52-year period (1951-2003). the doubling effect of carbon dioxide ( ) on temperature and precipitation was modeled as the most important climatic parameters. the resulting hythergraph and ambrothermic models for tabriz indicate monthly increases of temperature and precipitat...

background: with regard to the high prevalence of schizophrenia, research on brain structural changes in this disease has been one of the interesting issues among the medical scientists. in this research, brain mri findings of schizophrenic patients have been compared with non-schizophrenic ones. methods: this study was an analytic-comparative one in which two groups of schizophrenic and non-sc...

In this perspective paper, we examine possible premises of plasticity in the neural substrates underlying cognitive change. We take the special role of the medial temporal lobe as an anchoring point, but also investigate characteristics throughout the cortex. Specifically, we examine the dimensions of evolutionary expansion, heritability, variability of morphometric change, and inter-individual...

Research on the biology of aging seeks to enhance understanding of basic mechanisms and thus support improvements in outcomes throughout the lifespan, including longevity itself, susceptibility to disease, and life-long adaptive capacities. The focus of this review is the use of rats as an animal model of cognitive change during aging, and specifically lessons learned from aging rats in behavio...
