Abstract A new method is given for mathematical modeling of the coupled heat and mass transfer through porous media. The behavior moisture level function in vicinity critical value conductivity probability discussed, at general initial-, boundary conditions. Instead usually applied two partial differential equations parabolic type, a system hyperbolic containing also explicitly relaxation time constants used. solution presented function, when constant relevant temperature changes tends to...

Abstract A twofold refinement of the basic mathematical model for describing a coupled heat and mass transfer taking place in porous media is presented. The common application irreversible thermodynamics fluctuation theory phase transitions proposed calculating moisture level temperature. Instead parabolic partial differential equations, hyperbolic type equations are used. relaxation time constants, whose percolation state-dependence also taken into account, incorporated this formalism. Some...

After a brief overview of most important general features the nonclassical diffusion on base extended irreversible thermodynamics, relevant mathematical formulae are incorporated into formalism simultaneous convection–diffusion processes taking place in porous media. Then, using simplest variant equation, novel-type analytic solutions derived for transport with both subdiffusion and superdiffusion characters Lagrangian representation.

Abstract According to global inventories the agricultural field production contributes in a significant measure increase of concentration greenhouse gases (CO 2 , N O, CH 4 ) atmosphere, however their estimated data emissions soil origin differ significantly. Particularly estimates on nitrogen-oxides show great temporal and spatial variability while formations microbial processes are strongly influenced by biogeochemical physical properties (eg species, texture, water, pH, redox-potential...

Due its practical importance engineering applications, possibilities necessary refinements proposed and justified for general case simultaneous convection-anomalous taking place through porous bulk materials.

E-mobility is rapidly growing because of its clear economic and environmental benefits compared to conventional vehicles. This rapid deployment presents new challenges, such as peak demand charging losses, that need be minimised using energy management strategies. Smart a commonly used strategy manage in an office building. paper investigates EV losses for onboard chargers operated by three different methods, namely uncoordinated (dumb) charging, smart load balancing key performance...

Background: The use of escape rooms in education has gained traction as an innovative pedagogical approach to enhancing student engagement and alleviating learning-related anxiety. This study explored the effectiveness instructional tool geography education, with a particular focus on Generation Z students, who are known for their preference practical learning opportunities active engagement.Results: conducted educational experiment involving Hungarian 7th grade comparing room methodology...

Estimation of hydraulic conductivity in soils is challenging. The primary aim this study to demonstrate that such predictions may be improved if grading curves are appropriately quantified and described, as well by including density-related values relationships. Various saturated models were tested with the assumption would improve different curve statistics used. A unimodal database was elaborated using old new data. Three types permeability examined. One traditional variables consisting...

Tenyészedény-kísérleteket végeztünk egy szántóföldi tartamtrágyázási kísérletre épülve, hogy összehasonlítsuk a szerves- és ásványi trágyázás, valamint ezek kombinációjának hatását kukoricanövények szárazanyag-produkciójára N-felhalmozására, talajlevegő CO 2 -koncentrációjára.A Keszthelyen, Ramann-típusú barna erdőtalajon, 1963-ban beállított kísérlet alábbi kezeléseinek parcelláiról töltöttünk meg nagyméretű, 40 literes tenyészedényeket: a) kontroll; b) növekvő adagú istállótrágyázás (FYM)...

Az utóbbi időben az atmoszférába irányuló folyamatosan növekvő üvegházhatású gázok kibocsátása fokozott figyelmet érdemel. Míg a talaj felszínéről történő gázemissziót széleskörűen tanulmányozzák, viszonylag kevesen vizsgálják talajprofilon belül transzportját és koncentrációváltozását. Vizsgálatunk célja ezeknek folyamatoknak tanulmányozása volt bolygatatlan talajoszlopokban. Mivel talajlevegő mintavétele gyakran körülményes, különösen vízzel átitatott nedves talajokban, egy szilikoncsöves...
