Two distinctive features of Sasanian bridges are their designation as weir-bridges and function in the facilitation irrigation. This has often been used to emphasise a specific administrative centralisation. The author stresses continuity investments infrastructures, from Arsacids Islamic period via Sasanians. It is presented that members elite governing classes well private entrepreneurs provi...

Sasanian’s imperial policy aimed to construct new towns, massive irrigation infrastructures, and land modification bydepopulating rural areas in order to carry out massive agriculture projects particularly in Khuzestan. Shushtar with itsancient relics presents a unique chance to investigate some of these development activities, mainly in terms of irrigation.Several chief irrigation organs have ...

The improvement of irrigation systems in the Nile Delta is one of the most important attempts in Egypt to implement more effective irrigation technology by improving the existing irrigation networks. Demand delivery system in the existing irrigation network is using of mechanical gates structures to automatically divert water from one portion of an agricultural field to another in the desired a...

The coinage of the Sasanian Empire (224-651 CE) is not only the most important primary source for its monetary and economic history, but also of greatest relevance for its history and art history.Coin hoards are of pivotal importance for studying Sasanian coinage. On August 29,2007,two jars were unearthed during the construction work for the new border sentry post of “Havār-Barxāh-loh” in the P...

INTRODUCTION The aim of this study was to compare the efficiency of a sonic device (Vibringe), syringe irrigation, and passive ultrasonic irrigation in the removal of debris from simulated root canal irregularities. METHODS Root canals with 2 standardized grooves in the apical and coronal parts were filled with dentin debris. Three different irrigation procedures were performed with NaOCl (1%...

Site-specific irrigation is defined as delivering different prescribed depths of water to specific areas in irrigated fields. Since the 1990s, site-specific irrigation research has been expanded to include the delivery of water and nutrients to specific field areas based on soil type, soil moisture status, crop needs, and other user-defined objectives. A site-specific center pivot irrigation sy...

Objectives/Goals An enormous amount of real-time information that is available on the Internet can be accessed and used in traditional control systems to improve performance. The objective of this project is to design and build an autonomous control system that manages an irrigation system to save water using Internet-obtained weather forecasts and local-obtained rainwater level information. Me...
