Wind energy (WE), which is one of the renewable energy (RE) sources for generating electricity has been making a significant contribution to obtaining clean and green energy in recent years. Fitting an appropriate statistical ...

The present paper indicates that hydropower, including small hydropower plants (SHPs), may play a very important role in Poland’s energy transformation in the near future. The development of SHPs may also increase water ...

Every year the interest in biofuels, including biomethane, grows in Poland. Biomethane, obtained from biogas, is widely used in the Polish economy; the most important two applications are as gas injected into the gas grid ...

The bond-graph description of transport processes was applied to analyse all the phenomena related to the sorption of free electrolytes into the internal solution of a polymeric cation-exchange membrane (no cation exchange ...

Network thermodynamic analysis was used for bond-graph representation of simple pertraction in the agitated bulk liquid membrane. The output flux dependence on the membrane volume was analysed and compared with the same ...

Thermodynamic network analysis (TNA) was applied for modeling and theoretical description of the hybrid pertraction of univalent cations in the multimembrane hybrid system (MHS). Some numerical calculations were carried out ...

An analysis was carried out to show whether the Warmińsko-Mazurskie Voivodeship (Poland) could become energy selfsufficient. The technical potential of electricity and heat from renewable sources has been calculated. The ...

Introduction. Collagen is the main structural protein of the various connective tissues in mammals. Collagen, in the form of elongated fibrils, is mostly found in fibrous tissues such as tendons, ligaments and skin. The ...
