Článek uvádí posloupnost vývoje aplikací laserů v různých oblastech prostřednictvím vědecko-pedagogických pracovníků fyzikálního pracoviště Fakulty strojního inženýrství Vysokého učení technického v Brně. Těžištěm jejich činnosti byla holografie, holografická interferometrie, skvrnková interferometrie a měření přímosti a přímočarosti využitím vlastností základního modu laserového svazku. V článku je rovněž uveden vliv moderní optiky na vývoj studijních programů technického vzdělávání na této fakultě., Progress in development of different laser-based scientific applications carried out by researchers and lecturers at the Physics Department of Faculty of Mechanical Engineering, Brno University of Technology is presented in this article. Their activities included the development of various holography techniques, holographic interferometry, speckle interferometry and measurements of rectilinearity using the fundamental mode of the laser beam. The influence of modern optics on the development of study programs of technical education at this faculty is discussed as well., Miroslav Liška., and Obsahuje bibliografii
Bothitrema bothi (MacCallum, 1913), a monopisthocotylean monogenean (Bothitrematidae) found on gills and occasionally on the olfactory rosette within the nares of the bothid flounder, Scophthalmus aquosus (Mitchill, 1815), is distributed along the Atlantic coast of the USA from Woods Hole, Massachusetts to Delaware Bay. This study details aspects of the morphology, microecology and biology of the oncomiracidium, juvenile and adult. Adult worms occur almost exclusively between rakers on the first and second gill arches while juveniles occupy secondary gill filaments. Analysis of variance revealed significant arch, side and position effects. Worm attachment and position is maintained largely by suction generated by a circular seal using its 54 radially arranged accessory haptoral sclerotised elements and a marginal valve. A small anterior appendix with two marginal hooks lies dorsal to a deep anteromedian cleft in the haptor, which, together with wall muscles, creates and releases the negative pressure required for attachment. Four pairs of gland openings in the ventrolateral margins of the anterior adhesive area produce secretions for attachment. Operculate eggs with four rounded protuberances and a filament are laid individually at four-minute intervals at 22ºC. Hatching occurs in five days at 20°C. Oncomiracidia have two pairs of eyes, with the posterior pair fused, show both positive and negative phototaxis and swim at a mean rate of 5.2 mm/s at 22°C. Larvae have a circle of 16 hooks and a pair of hamulus primordia. Other accessory haptoral sclerotised structures arise de novo in juveniles after attachment to the host. These data will help to resolve more clearly the relationships of the Bothitrematidae within the Monopisthocotylea.
