Dear Editor,Karschiellidae are a mysterious group of earw.gs that attract attention not only because of their interesting appearance and unexplained w.y of life but also mainly due to their unclear *** phylogenetic relationships of karschiellids remain speculative even 120 years since the family w.s described,above all due to the unavailability of DNA-grade material for molecular phylogenetic *** study includes successfully sequenced representatives of the Karschiellidae for the first time,and a probable evolutionary scheme and natural classification of karschiellids are proposed based on the constructed multigene phylogeny.

The global aw.reness and utilization of superplasticizers (SPs) in concrete have significantly contributed to developing resilient and sustainable infrastructure. Despite this, many developing nations face limited adoption of SPs in construction practices due to a lack of know.edge. This study provides a concise overview.of concrete’s mechanical and durability properties, comparing formulations w.th and w.thout superplasticizers. The focus is on compressive and flexural strengths, modulus of elasticity, w.ter sorptivity, and chloride penetration. The results underscore the considerable improvement in both mechanical and durability properties w.en SPs are incorporated. The study recommends the w.despread use of SPs, particularly in developing countries, to enhance the longevity of concrete structures.

The stability of a set of spatially constant plane w.ve solutions to a pair of damped coupled nonlinear Schrödinger evolution equations is considered. The equations could model physical phenomena arising in fluid dynamics, fibre optics or electron plasmas. The main result is that any small perturbation to the solution remains small for all time. Here small is interpreted as being both in the supremum sense and the square integrable sense.
