We present the results from our ongoing spectroscopic survey targeting low-mass white dwarf binaries, focusing on the southern sky.We used a Gaia DR2- and Diffuser Oil eDR3-based selection and identified 28 new binaries, including 19 new extremely low-mass (ELM) white dwarfs, one short period, likely eclipsing, DABZ, and two potential LISA binaries
Bridge flutter phenomenon presents an important criterion of instability, which should be considered in the bridge design phase.This paper presents different bridge flutter methods which can be used to solve the flutter problem.Most commonly used frequency-domain approach is based on the formulation of aero elastic forces with frequency dependent c
How is human reality presented to us in phenomenological experience? It is the one we see daily in our personal and social life.We are made of matter, we are part of the evolutionary universe.In addition, a psychic life is formed in us: sensation, a system of perceptions, an integrated consciousness, a condition of psychological subject; We produce
Mediterranean macroalgal assemblages in areas invaded and non-invaded by Caulerpa racemosa var.cylindracea were compared and trapped sediments were characterised.Results showed that assemblages invaded by C.racemosa var.cylindracea differed greatly from non-invaded ones: encrusting and erect algae, both articulated and foliose, decreased in invaded
