  • Examining the influence of sludge from municipal wastewater treatment plants processed by Euphore installations on the quantity and quality of rapeseed and soybean production 
    Chiorescu, Esmeralda; Filipov, Feodor (MDPI, 2021-03-24)
    Sludge management is a complex issue due to the environmental standards. It is required that the wastewater treatment activity be in close connection with the controlled recovery and stor age of sludge. Thus, by using ...
  • Expresii analitice pentru coeficienţii de înmagazinare ai unui sol stratificat 
    Chiorescu, Esmeralda; Popescu, Șt. (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2008)
    The paper is defining the average and local soil storage coefficients, for a layered soil, with relatively shallow water table. Then, by means of an adequate law for the suction’s distribution on soil’s level and the ...
  • Fighting water hammer in the pressurized adduction works of hydrotechnical systems 
    Chiorescu, Esmeralda; Filipov, Feodor; Jităreanu, Sergiu (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2014)
    This paper presents an experimentally proven mathematical model of determining theoretically the functional characteristics of an overpressure safety valve of open type, with a spring. These were implemented in a ...
  • Generalization of the fundamental equation of the reservoir 
    Chiorescu, Esmeralda; Jităreanu, Sergiu; Țigaret, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2010)
    In paper (Vâscu V., Gavrilaş G, Chiorescu E., 2001) a differential equation is derived and solved analytically, under certain simplifying assumptions, as the authors called the fundamental equation of the pool, which is a ...
  • Hydrological and hydraulic research for re-equipping an irrigated plot with pressurized pipelines 
    Chiorescu, Esmeralda; Cojocaru, Paula (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2015)
    Considering these factors we have decided that the following basic data are necessary for modernizing an irrigation plot: the climate studies for the last three decades regarding monthly precipitations and potential ...
  • The influence of Acuastoc on soil moisture and some morphophysiological properties in maize crop 
    Galeș, Daniel-Costel; Teodorescu Soare, Eugen-Gabriel; Filipov, Feodor; Țopa, Denis-Constantin; Chiorescu, Esmeralda (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2017)
