In this paper, we have tried to analyze and asses the process of formation and spatial – structural evolution of Iranian-Islamic cities through Tehran case study as well as how to organize and effecting different factors specially modernism on urban elements. Also we have discussed about formation and emergence of Tehran and the effect of different pre modernism and postmodernism socio-economic...

Asymptotically exact and nonlocal third order nonlinear evolution equations are derivedfor two counterpropagating surface capillary gravity wave packets in deep water in thepresence of wind flowing over water.From these evolution equations stability analysis ismade for a uniform standing surface capillary gravity wave trains for longitudinal perturbation. Instability condition is obtained and g...

Introduction: The selection of suitable beam angles and weights in external-beam radiotherapy is at present generally based upon the experience of the planner. Therefore, automated selection of beam angles and weights in forward-planned radiotherapy will be beneficial. Material and Methods: In this work, an efficient method is presented within the MATLAB environment to investigate how to improv...

The data set represents the Regional Meteoric Water Line (RMWL) for Yucatan Peninsula (Mexico), a region with karstic aquifers but little knowledge of isotopic composition meteoric water. This paper comprises water collected from November 2018 to 2019 as monthly composite samples expressed weighted mean precipitation 16 locations across Peninsula. RMWL was δ2H = 7.803 δ18O + 12.075, slope and i...

There are many proposed models for protein domain evolution. The main contention [1], however, is between divergent [2] and convergent [3] models of evolution. Divergent evolution proposes that there was an ancestor to all domains that we see today and consequently all domains are historically related to each other. Convergent evolution claims that chance is largely responsible for the appearan...

Important karstic aquifers exist in west and southwest of Iran. Mansour-Abad Karstic region is located in Shiraz, southwest of Iran. It supplies the drinking water for the whole area by 4 pumping water wells, some of which have water turbidity problem. The present research aims to assess the hydrogeochemistry and turbidity problem in the karstic water production wells. The EC varies between 703...

Today, humans inhabit most of the world's terrestrial habitats. This observation has been explained by the fact that we possess a secondary inheritance mechanism, culture, in addition to a genetic system. Because it is assumed that cultural evolution occurs faster than biological evolution, humans can adapt to new ecosystems more rapidly than other animals. This assumption, however, has never b...
