Hypergel is a novel material that uses a combination of several chemical structures which thus together create a relatively complex copolymer. It provides many improvements to contact lenses wearers related to comfort and biomechanical properties influence on the corneal tissue without the presence of silicone. This material uses knowledge coming from biomimetics. Thanks to its innovations this material is very positive evaluated by clients. and Hypergel je nový materiál využívající kombinaci několika chemických struktur, které dohromady tvoří relativně složitý kopolymer. Ten nabízí nositelům mnohá zlepšení týkající se komfortu při nošení kontaktních čoček a vlivu biomechanických vlastností na rohovkovou tkáň, a to bez přítomnosti silikonu. Tento materiál využívá poznatky z biomimetiky. Díky svým inovacím je klienty velmi kladně hodnocen.
In 2019, a metal-detector find of an exceptionally well-preserved weapon was made in the complex of Ždánice Forest. We can classify it as a long-sword of Type XVIa, H1, 1b (according to Oakeshott 1964; Głosek 1984, 39–40, Fig. 4) and date it to the turn of the 15th century. Its blade was marked on both sides with three marks taking the form of a forked cross, a diagonal consisting of three equilateral crosses and, finally, a bishop's crosier. The weapon was assembled from a blade of Passau provenance and hilt-components characteristic of the wider Central European region. These and other facts concerning the sword were obtained through detailed analysis, which this study introduces.
