    [EN] The holotypes of three species inquirendae siphonophores collected in Japanese waters and described by Tamiji Kawamura were re-examined. It is considered that Bathyphysa japonica is not a valid species because there are no characters that distinguish it from other Bathyphysa species; Athorybia longifolia is an incorrectly described specimen of A. rosacea; and Forskalia misakiensis is a wrongly described and badly preserved specimen, probably of F. edwardsi[ES] Han sido reexaminados los holotipos de tres sifonΓ³foros species inquirendae recogidos en aguas japonesas y que fueron descritos por Tamiji Kawamura. Se considera que Bathyphysa japonica no es una especie vΓ‘lida porque no se observan caracteres que la distingan de otras especies de Bathyphysa. Athorybia longifolia es un espΓ©cimen de A. rosacea descrito incorrectamente; y Forskalia misakiensis es un espΓ©cimen descrito erroneamente y preservado inadecuadamente, probablemente de F. edwardsiThis study was sponsored by the Japanese Society for the Promotion of SciencePeer reviewe

    In the present study, glass-ceramic material used for hydraulic fracturing technology has been investigated. Density and compression strength depending on the initial composition and firing time have been examined. The resulting material is characterized by high compressional strength, with a low value of bulk density, which is provided by the internal closed porosity created by adding the gasifier
