Reformierakonna esimees Kaja Kallas ütleb, et vastuse, kas Eesti Energia maksis Nelja Energia eest liiga kõrget hinda, saab teada börsilt. Kaja Kallas ootab Nelja Energia tehingu kohta tõde - Majandus
ABSTRACT. In this study, a new vanadium extraction process from vanadium titano-magnetite(VTM) featuring calcification roasting and (NH 4) 2 C 2 O 4 solution leaching has been proposed. Compared with the traditional sodium roasting, the calcification roasting can avoid the production of waste gas and the sodium free tailings can be used for iron …

Kui energia tootmine ületab tarbimise (nt. tugev tuul) tekib vajadus ülejäänud energia salvestamiseks, et hoida seda ajaks mil tuulevaikusest või tarbimise kasvust tingituna on vaja rohkem energiat kui turbiinid antud hetkel toota suudavad. Väiksemate ja autonoomsete turbiinide puhul sobivad salvestamiseks akud, kuid võrku ühendatud ...
The release of V from vanadium titano-magnetite, a predominant natural source of V, was studied under light irradiation. The release rate of V from vanadium titano-magnetite was accelerated by light irradiation, and the oxidation of V was detected. The essence of the photopromoted release of V is that the immobile low valence V is transformed to the …
The Ecoinvent database provided the reference life cycle inventory (LCI) datasets for materials used (Wernet et al., 2016), including primary extraction (mining), refining, and fabrication.
Methods of chemical analysis, XRD, and pH monitoring are adopted in order to study wet extraction of Fe, V and Ti based on activated reduction, and the control conditions as well as the degree of recovery are determined. The primary-leaching in NaHCO3 saturated solution followed by final-leaching via carbonization is possible, and the leaching ratio for Na …
Päikesepatarei süsteemide projekteerimisel tuleb arvestada mitmete oluliste teguritega, et tagada optimaalne jõudlus ja tõhusus. Akusalvestussüsteemidel on ülioluline roll päikeseenergia süsteemide eeliste maksimeerimisel, kuna need võimaldavad koguda ja salvestada kõrge päikesekiirguse perioodidel tekkivat üleliigset energiat.
"Tõde ja õigus" on A. H. Tammsaare kirjutatud romaan. Kõik aimasid, et sõnu ei kuulutata tõe ja õiguse pärast, vaid selleks, et neist oleks kasu. Tõde ja õigus isegi pole muud kui see, mis kasulik. (III, XXIV ptk)

Soil is a vital contributor to the production of nitrous oxide (N 2 O), a potent greenhouse gas, through the nitrogen cycle, which can be influenced by accumulated vanadium (V) in soil but it is less pronounced. This work investigated the response of soil N 2 O fluxes along with major nitrogen cycle products (ammonium, nitrate, and nitrite) to different vanadium …
