We report about testing a new mobile and sustainable water sample digestion method in a preliminary field trial in Ethiopia. In order to determine heavy metals at the ultra-trace level by stripping voltammetric techniques in water samples from Awash River, we applied our new method of solar UV-assisted sample pretreatment to destroy the relevant interfering dissolved organic matter. The field t...

Among the major sources of energy supply systems, hydroelectric power plants are more common. Energy supply during peak hours and less environmental issues are some of the most important advantages of hydroelectric power plants. In this study, designing parameters to supply maximum amount of energy was determined by using the simulation-optimization perspective and combination of IWO-WEAP model...

This paper examines the effects of increased intermittency, caused by climate change, on strategic hydroelectric production when wind power is integrated with hydroelectricity. It is shown that increased uncertainty in water inflows caused by climate change raises hydroelectric output and increases the probability of overflow in future periods. The increased variability of wind speeds due to cl...

it is expected that, compared with other power plants, changes in fuel cost for power plants in the deregulated electricity market leads to changes in the generation capacity of wind power plants. to quantify this effect, this article aims at modeling energy generation capacity and supply or distribution of different power plants as opposed to those of wind power plants. the proposed model was ...

water hammer is one of the destructive hydrodynamic phenomena which is established in most pumping stations, transmission lines and hydroelectric power plants. this phenomenon gives rise to abnormal pressures, cavitation occurrence and finally pipe explosion and disturbance of the whole system. to control the maleffects of this event, different methods are devised. one of which is sometimes eno...
