Symmetry Analysis of Some Basic Structural Properties of Incommensurately Modulated Crystals by Projective Representations of Unimodular Groups

Csaba Mészáros, István R. Nikolényi, Ágnes Bálint

physica status solidi (b) > 257 > 3 > n/a - n/a

Projective representations of the unimodular groups are applied in the general symmetry theory of incommensurately modulated crystals. It is demonstrated that the algebraic condition relevant for the existence of line groups can be directly connected to those related to linear projective groups. As a concrete application example, the formalisms of the thermodynamic modelling of the structural phase...

Contribution of Agricultural Field Production to Emission of Greenhouse Gases (Ghg)

Ágnes Bálint, Sándor Hoffmann, Attila Anton, Tibor Szili-Kovács, more

Ecological Chemistry and Engineering S > 2013 > 20 > 2 > 233-245

According to global inventories the agricultural field production contributes in a significant measure to increase of concentration of greenhouse gases (CO₂, N₂O, CH₄) in the atmosphere, however their estimated data of emissions of soil origin differ significantly. Particularly estimates on nitrogen-oxides emissions show a great temporal and spatial variability while their formations in microbial...

Investigation of ultra- and nanofiltration for utilization of whey protein and lactose

Ramadan Atra, Gyula Vatai, Erika Bekassy-Molnar, Agnes Balint

Journal of Food Engineering > 2005 > 67 > 3 > 325-332

Ultrafiltration is one of the most fascinating technologies, which has been introduced for application in the dairy industry. Ultrafiltration makes it possible to improve the quality of traditional dairy products, to create new food staffs, to utilize dairy by-products (such as whey) to a much greater extent for human nutrition and to prepare milk ingredients to be used in the entire food industry...

From teaching towards learning in flowsheeting and simulation in chemical engineering

Ágnes Bálint, Ferenc Tátrai

Computers and Chemical Engineering > 1999 > 23 > Supplement > S619-S622

With the democratisation of higher education the proportion of the relevant age group enrolled into universities and colleges has dramatically increased in the last decades. To satisfy the needs of mass higher education and also of life-long learning, the role of the teacher is gradually changing. The emphasis is shifting from teaching towards learning. The methods of open and distance learning became...

Industrial application of CAD in dairy

Ágnes Bálint

Computers and Chemical Engineering > 1999 > 23 > Supplement > S765-S766

Whey processing alternatives were investigated with the help of Computer Aided Design. Mass and energy balances were calculated, process units were sized, and economic analysis was conducted. Using IRR and ACF methods for calculatind profatibility methods optimum economic strategies were suggested for WPC processes.
