Employing non-conventional water resources using treatment and recycling is considered as the main resource in addressing future water scarcity. Although non-conventional water recycling has been investigated in details in the literature, its impacts on irrigation-fertilizing systems have not been discussed using thermoeconomic analysis.  In this case study, using a hydroponic greenhouse system...

INTRODUCTION Estimating groundwater inflow into a tunnel before and during the excavation process is an important task to ensure the safety and schedule during the underground construction process. CASE DESCRIPTION Here we report a case of the forecasting and prevention of water inrush at the Jinping II Hydropower Station diversion tunnel groups during the excavation process. The diversion tu...

There is a pressing need to improve food security and reduce environmental impacts of agricultural production globally. Two of the proposed measures are diet change from animal-based to plant-based foodstuffs and reduction of food losses and waste. These two measures are linked, as diet change affects production and consumption of foodstuffs and consequently loss processes through their differe...

Water footprints and virtual water flows have been promoted as important indicators to characterize human-induced water consumption. However, environmental impacts associated with water consumption are largely neglected in these analyses. Incorporating water scarcity into water consumption allows better understanding of what is causing water scarcity and which regions are suffering from it. In ...

Introduction: Due to water scarcity and increased water consumption during the past years, the importance of water in terms of transmission of diseases, as well as Iran's climate, groundwater aquifers are known as the most important resources of drinking water supply. Using the Water Quality Index (WQI) is considered as strong managerial tool for decision making in water resource management. Th...

uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...

The optimal management of ground water consumption is impossible without proper knowledge of water distribution, aquifer territories, and water table fluctuations. Humans are faced with the problem of water scarcity, due to various reasons such as population growth, droughts and reduced rainfall, and industrial progress and its impact on water resources. The purpose of this study was to determi...

Freshwater scarcity is increasingly perceived as a global systemic risk. Previous global water scarcity assessments, measuring water scarcity annually, have underestimated experienced water scarcity by failing to capture the seasonal fluctuations in water consumption and availability. We assess blue water scarcity globally at a high spatial resolution on a monthly basis. We find that two-thirds...

Introduction: The main aim of this study was quality and quality analysis of electronic and chemical industrial wastewater in the mega city of Tehran. This research was conducted in two phases, first: water consumption and second: quantity and quality analysis of wastewater in such industries. Methods: Right now there are 59 chemical and electronic industries with over 50 personnel in Tehran....

abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
