All the geophysical phenomena including river networks and flow time series are fractal events inherently and fractal patterns can be investigated through their behaviors. A non-linear system like a river basin can well be analyzed by a non-linear measure such as the fractal analysis. A bilateral study is held on the fractal properties of the river network and the river flow time series. A movi...

In this study, we conducted flood mapping of a hypothetical dam break by coupling the Hydrologic Engineering Center’s Modeling System (HEC-HMS) and River Analysis (HEC-RAS) models under different return periods inflow. This study is presented as case on Kesem embankment in Ethiopia. Hourly hydrological meteorological data high-resolution land surface datasets were used to simulate design floods...

This paper provides information on the geographic distributions of two cyprinid species: Hemiculter leucisculus (Basilewsky, 1855) and Alburnus caeruleus Heckel, 1843, in the world and the entire drainage systems in Iran. The new distribution records were taken from Maroon River (Jarrahi River system) and Chardaval River (Karkheh river system), both in Tigris River basin showing wide and narrow...

Blockade of the renin-angiotensin system (RAS) is well recognized as an essential therapy in hypertensive, heart, and kidney diseases. There are several classes of drugs that block the RAS; these drugs are known to exhibit antifibrotic action. An analysis of the molecular mechanisms of action for these drugs can reveal potential differences in their antifibrotic roles. In this review, we discus...

The renin-angiotensin system (RAS) has mainly been categorized as a circulating and a local tissue RAS. A new component of the local system, known as the intracellular RAS, has recently been described. The intracellular RAS is defined as synthesis and action of ANG II intracellularly. This RAS appears to differ from the circulating and the local RAS, in terms of components and the mechanism of ...

Considering characteristics of high river density, special underlying surface in plain river network region, and municipal drainage system function, river network drainage unit model is proposed, which is defined as a region surrounded by main river or embankment. Flood storage variety and control projects regulation of small rivers in each unit is simulated. With drainage catchment as an objec...

Background and purpose: Metadiscourse markers (MDMs) play a significant role in academic witting. They act as a bridge between writers and readers and make a text more understandable. Therefore, this study aimed at investigating the use of MDMs in introduction, methods, results, and discussion (IMRaD) sections of English medical research articles (RAs) published in Iranian and American ISI jour...
