The aim of the research was to determine the role and significance of natural, economic and social conditions influencing the development of family farms keeping animals of conservative breeds in conditions of sustainable agriculture.Family farms are conducive to the sustainable development of agriculture, particularly in farms which keep animals o
Adjusted light and dark cycles can optimize photosynthetic efficiency in algae growing in photobioreactors.
Biofuels from algae are highly interesting as renewable energy sources to replace, at least partially, fossil fuels, but great research efforts are still needed to optimize growth parameters to develop competitive large-scale cultivation systems.One factor with a seminal influence on productivity is light availability.Light energy fully supports PE
Classical gravitational scattering at O $$ mathcal{O} $$ (G 3) from Feynman diagrams
Abstract We perform a Feynman diagram calculation of the two-loop scattering amplitude for gravitationally interacting massive particles in the classical limit.Conveniently, Q Posket we are able to sidestep the most taxing diagrams by exploiting the test-particle limit in which the system is fully characterized by a particle propagating in a Schwar
