The fractal Toda oscillator with sunflower horse halter an exponentially nonlinear term is extremely difficult to solve; Elias-Zuniga et al.(2020) suggested the equivalent power-form method.In this paper, first, the fractal variational theory is used to show the basic property of the fractal oscillator, and a new form of the Toda oscillator is obta
The feeding habits of sand smelt, Atherina boyeri Risso, 1810 in the mouth of the Mala Neretva River were studied by examining the stomach contents of 1236 fishes collected from March 2001 to February 2002.Thirteen different food categories were identified.The greatest diversity was recorded in winter, especially in January, when 11 categories were
In alpine Australia, Orthoptera are abundant, dominant herbivores, important prey species, and hosts for parasites and parasitoids.Despite the central role of orthopterans in alpine ecosystems, the impact of parasites on orthopteran populations is under-explored.In this study we describe the relationship between parasite prevalence and host sex, bo
The paper presents its contribution to tracking control design of mechanical systems in underactuated mode conditions, i.e.when the number of actuators is less than the number of possible control inputs.Fully actuated mechanical systems are quite well-researched and 3mzfe engine for sale controller designs are well-developed for them as well.Howeve
