Water quality and metal contents of sediments were measured in Zayandeh-Rood River. Zayandeh-Rood is one of the most important rivers of Iran. The river water is used for drinking, industrial and agricultural purposes. The anthropogenic impact on the river over the last three decade has proven to be extremely negative due to the quick development of industry. Physico-chemical parameters of wate...

Advances in electronics nowadays facilitate the design of smart spaces based on physical mash-ups of sensor and actuator devices. At the same time, software paradigms such as Internet of Things (IoT) and Web of Things (WoT) are motivating the creation of technology to support the development and deployment of web-enabled embedded sensor and actuator devices with two major objectives: (i) to int...

Diatoms samples in Zayandeh Rood Dam Lake were taken in four stations from surface, 0.5 and 3 m depths of water in three replicate by Nansen sampler. Additional samples were taken from the surface with plankton net. Diatoms samples fixed with 4% formaldehyde and were concentrated and identified using microscope at 400 x. Salinity, NO3, PO4 and SO4 were measured using standard methods (APHA). In...

A Steiner triple system (STS) (a twofold triple system (TTS)) is a pair (V, B) where V is a v-set, and B is a collection of 3-subsets of V called blocks or triples such that every 2-subset of V is contained in exactly one [exactly two] blocks. The number v is called the order of the STS or TI'S. It is well-known that an STS of order v exists if and only if v 1 or 3 (mod 6), and a T r s of order...

Jon was born on April 7, 1926 in Scheveningen, a town situated on the coast of the Netherlands. At the end of the Second World War, he began his medical studies at Leiden University. After finishing these, Jon was active as a ‘house doctor’, and visited many of his patients in the country areas. He considered this as one of the best medical learning experiences of his early career, as he was co...

The purpose of this study was to manage the risks of Paveh Rood Dam at constructional phase by integrating TOPSIS & RAM-D techniques. After investigating the environmental conditions of the study area and the technical specifications of the dam, the risks of the dam construction were listed in a questionnaire. After analyzing the given scores by Preliminary Hazard Analysis (PHA), Technique for ...
