No full textThe study was carried out in two species (Acromitus maculosus and A. flagellatus) in order to check whether the collected species are only morphologically distinct or indeed congeneric species of Acromitus as reported by earlier authors/previous reports. The samples (72 nos.) are collected during the pre-monsoon seasons (mid-February to end May) of 2019, 2020, 2021 and 2023 from the stake-net fishery operating in the Kumbalam estuary (Lat. 9054' 14" N;Long. 760 18' 17" E) of Vembanad lake, Kerala India. The Scyphozoan jellyfish Acromitus maculosus and A. flagellatus are considered to be valid species under the genus Acromitus. In laboratory, following morphometric measurements of each specimen were taken for analysis such as Oral Arm Length, Oral Arm Stalk, Oral Arm Wing, Radius of Oral Disk, Ring Canal Radius, Inner Muscle, Outer Anastomosing Canal System and weight of the specimens. On analysis, specimens of A. maculosus and A. flagellatus from Kochi backwaters, India indicate that the two putative species differ only in their morphologic features and that there are no significant variations in their morphometric and genetic traits except for the medusa diameter- stabilized wet weight relation. On DNA analysis, the genetic distance in the CO1 gene sequence of the putative species A. maculosus and A. flagellatus (0.4%) were below the threshold value suggesting that the two species are similar in their genetic traits. As the observed variations in two species were limited to morphologic features with transitional morphologic forms in between and the lack of significant morphometric and/ or genetic variations among the two putative species necessitate a through recheck on the species status of A. maculosus and A. flagellatus

Towards the lava flow physical modelling using Olson's dynamical analogies, similarity criteria and dimensional analysis implemented for the melting polymers in SEM or ESEM sub-chambers
No full textThe "lava flow modeling" is known to be a very extensible term covering different processes from the analog experiments of the lava flow emplacement and direct digital simulations (such as 3D modeling of lava flows using smoothed particle hydrodynamics and FEM-based modeling including finite-difference numerical approximations) to SCIARA- and MAGFLOW-based cellular automata lava flow modeling and its applications for hazard predictions. Despite this fact the physical basis of all the above models includes the rheology of the underlying substance. Consequently, it is possible to simulate the effects/phenomena of lava distribution, including bifurcation-determined ones, using the unified principles, explicated from the physical chemistry and rheology of viscous polymers, including reaction-diffusion mechanisms and nonlinear wave's physics. Our study was focused on reconsideration of the analog modeling based on physical similarity conditions and criteria, which made it possible to simulate such phenomena using uniform or similar equations, which can be explicated not only for linear scales, but also for nonlinear systems and non-stationary boundary conditions. The aim of our work is physical modeling of the lava flow based on chemically different media using hydrodynamical and hydraulical similarity criteria and principles of the unified interpretation of the wave phenomena in the framework of nonlinear physics. Also we apply the scaling principles for microscopic simulation of the effects, observed on either mesoscopic or macroscopic levels, for direct observation of them at the microscopic level using complex electron microscopy instrumentation
