this paper gives an account of the implementation of geomorphological, hydrogeological, hydrochemical and isotopic techniques to understand groundwater-surface water interactions in a multiple use area, los padres-la brava corridor (se of buenos aires province, argentina). the isophreatic map reveals a regional flow from the sw to ne sector, and allowed us to define the effluent-influent behav...

Climate change poses significant challenges in terms of water scarcity, environmental crisis, and economic uncertainty. This situation drives an increasing need to pursue more sustainable futures conserve maximise the use resources whenever possible. The EU-funded H2020 NextGen project aimed boost sustainability using new novel technologies approaches implemented within cycle, efficient water-e...

A sizing algorithm for a photovoltaic water pumping installation composed of photovoltaic panels, battery' bank, DC/AC converters and a water pump is presented. Considering criteria related to the battery' bank safe operation, fulfilling the water volume needed by the crops and ensuring a continuous operation of the pump, the algorithm decides the size of the installation' compon...

combined cycle performance can be improved by improving the performance of gas turbine based topping cycle. amongst various options the effective cooling of gas turbine blade for realizing the higher turbine inlet temperatures is one of the attractive options. the present paper deals with the thermodynam-ic analysis of advanced technology gas/steam combined cycle based power plant having closed...

Abstract The objective of this work was to determine the accumulation silicon in plant components cauliflower (Brassica oleracea var. botrytis) grown with different levels water replacement and rates Si. experimental design a randomized complete block three conditions (40, 70, 100% evapotranspiration), four Si (0, 50, 100, 150 kg ha-1), replicates. Daily evapotranspiration determined constant t...

dynamic economic load dispatch is one of the most important roles of power generation’s operation and control. it determines the optimal controls of production of generator units with predicted load demand over a certain period of time. economic dispatch at minimum production cost is one of the most important subjects in the power network’s operation, which is a complicated nonlinear constraine...

Impedance spectroscopy (IS) is a non-destructive testing (NDT) method [4,5,7] ranking in the electrical engineering measuring method group. It outputs data providing information on material electric and dielectric properties. Microscopically inhomogeneous materials are frequently used in the building industry. Unfortunately, the impedance spectroscopy results and their characterization on the b...
