Featured in this issue is an article by Jiří Wiedermann, the director of the Institute of Computer Science of the ASCR, on periodical research assessment in the field of Computer Sciences in the Netherlands from 2002-2008. All publicly funded research in the Netherlands is evaluated once every six years. The evaluation system aims at three objectives regarding research and research management: improvement of the quality of research through an assessment carried out in accord with international standards of quality and relevance; improvement of research management and leadership; seeking higher levels of accountability by research organizations and funding organizations, government and the society at large. and Jiří Wiedermann.
Painting the Jungle, the amply illustrated publication of an excellent Czech author of scientistific drawings, Jan Dungel, brings together fascinating photos and drawings of the jungle from his journeys through South America - Amazonian rainforests, savannahs (grassland with widely spaced trees), Llanos (extensive systems of grasslands on flat plains) or in Pantanal (the world´s largest wetland area in Brazil, Bolivia and Paraguay). and [autor recenze] Jan Zima.
Již od sklonku 19. století se k záznamu astronomických pozorování používaly tzv. fotografické desky. S cenným odkazem svých předchůdců pracuje doc. René Hudec z Astronomického ústavu AV ČR v Ondřejově již od roku 1973, kdy jako student astronomie a astrofyziky Matematicko-fyzikální fakulty UK praktikoval na observatoři Sonneberg v bývalé NDR. Právě zde se nachází největší evropský archiv čítající téměř 300 000 kusů. Ostatně, i první odborná práce doc. Hudce zahrnovala výzkum H-alfa hvězd v mlhovině Severní Amerika na fotografických deskách Schmidtovy kamery v Sonnebergu, na jehož základě později vznikla i jeho první vědecká publikace. and Luděk Svoboda.
Professor Pavel Zemanek and his colleagues at the Institute of Scientific Instruments (1St) of the ASCR built a laser that moves tiny spheres of polystyrene floating in water While in science fiction programs such as "Star Trek," tractor beams are used to move massive objects, the unique research published in Nature Photonics (2013, 7, 123-127) is limited to moving microscopic particles. Changing the way the light is polarized changes the direction the spheres move. The ISI scientists also found that at certain sizes, the spheres arrange themselves into neat rows as they move, bound by the light itself. The practical applications could be diverse. The tractor beam is very selective in the properties of the particles it acts upon, so one could pick up specific particles in a mixture. For example, this laser could be used to separate white blood cells. and Luděk Svoboda.
