- Description:
- Díky optické mikroskopii mohla vzniknout buněčná biologie. Významnou roli hraje tato mikroskopie též v materiálovém výzkumu a dalších vědních oborech, jakož i mnoha praktických činnostech. Od konce 19. století je zásluhou Lorda Rayleigha a Ernsta Abbeho známo, že rozlišovací schopnost standardních optických mikroskopů je rovna zhruba polovině vlnové délky použitého světla. V uplynulém čtvrtstoletí však vzniklo několik převratných metod, které zlepšily rozlišovací schopnost optických mikroskopů natolik, že místo o mikroskopii můžeme dnes již mluvit o nanoskopii., The invention of light microscope belongs to one of the most fundamental contributions ever made to the advancement of biology. This imaging technique played also an important role in material science and other disciplines, as well as in many practical applications. Before the end of the 19th century. Lord Rayleigh and Ernst Abbe recognised that the resolution limit of optical microscopes is about half the wavelength of the light used. In the past two decades, however, several revolutionary methods were established which improved the resolution of optical microscopes to such an extent that, instead of microscopy, we can now talk about optical nanoscopy., Jaromír Plášek., and Obsahuje seznam literatury

4. Weak chain-completeness and fixed point property for pseudo-ordered sets
- Creator:
- Bhatta, S. Parameshwara
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- pseudo-ordered set, trellis, complete trellis, fixed point property, and weak chain completeness
- Language:
- English
- Description:
- In this paper the notion of weak chain-completeness is introduced for pseudo-ordered sets as an extension of the notion of chain-completeness of posets (see [3]) and it is shown that every isotone map of a weakly chain-complete pseudo-ordered set into itself has a least fixed point.
