In this paper we derive semi-empirical Cepheid period-luminosity (P-L) relations in the Sloan ugriz magnitudes by combining the observed BV I mean magnitudes from the Large Magellanic Cloud Cepheids (LMC) and theoretical bolometric corrections. We also constructed empirical gr band P-L relations, using the publicly available Johnson-Sloan photometric transformations, to be compared with our sem...

Digital topology was first studied in the late 1960's by the computer image analysis researcher Azriel Rosenfeld[9]. The digital plane is a mathematical model of the computer screen. In this paper we investigate explicit forms of GαO-kernel and g-closed sets in the digital plane. Also we prove that the digital plane is an T1/2 ** space.

Scientific reference management has become crucial in rapidly expanding fields of biology. Many of the reference management systems currently employed are reference centric and not object/process focused. BrainSnail is a reference management/knowledge representation application that tries to bridge disconnect between subject and reference in the fields of neuropharmacology, neuroanatomy and neu...

The paper deals with pedagogical heritage of A.V. Usova (1921-2014) that yields insights into problems interdisciplinary relationship in the school science education system. Her fundamental works were used as teaching guides preparation physics teachers all universities Soviet Union and Russia. In this study, professor is not an researcher; she a researcher interdisciplinarity. Here provided sh...
