The article discusses the display of computer generated holograms of 3D objects using a binary amplitude spatial light modulator. More precisely, it deals with binarization of a diffractive structure using dithering noise. It concludes that the dithering method is suitable for simple diffractive structures such as diffractive gratings, but fails to provide a good binarization of computer generated holograms of 3D objects., Článek se zabývá zobrazením počítačem generovaného hologramu 3D objektu na binárním amplitudovém prostorovém modulátoru světla, respektive binarizací difraktivních struktur. Rozvíjí myšlenku binarizace difraktivní struktury pomocí techniky ditheringu. Dospívá k závěru, že technika je vhodná pro jednoduché struktury typu difrakční mřížky, ale není vhodná pro počítačem generované hologramy 3D objektu., and Pokračování článku v příštím čísle
Consideration of mass transfer and mass loss processes allows the explanation of the existence of well determined groups of binaries, such as Algols, cataclysmic variables, massive and low masa X ray binaries. The characteristics of these groups are briefly outlined, and evolutionary scenarios are discussed. The importance of detailed observations for advances in evolutionary computations are stressed. It isargued that, although the linka between the mentionned groups of binaries and their progenitors is rather well known, the situation is completely different if the detailed evolutionary history for a given system is required.
The area of biomedicine is one of the fastes developing areas of science and technology. The perception of its possible and wxpected positive or negative impacts results in the growing number of bioethical discussions in scientific community, politics and public. Their intensity, focus and used methods differ from country to country. he authors of the prologue have tried to map the state of the art and expected development of bioethical discussion in the coutnries of Middle and Eastern Europe. In the beginning, they addressed the bioethical experts with short questionnaire from 7 "new" European coutries (Croatia, Czech Republic, Hungary, Poland, Romania, Slovakia and Slovenia) and two "old" European coutries (Germany and Austria). In the end, seven experts have responde their question (Czech Republic, Poland, Romania, Slovakia, Austria and Germany) and expressed their expectations and difficulties of the development of bioethical discussions and institutionalisations in their countries. The authors summarize in the prologue the most interesting results. and Gerhard Banse, Monika Bartíková.
From the bioarchaeological and morphofunctional point of view, a skeletal deformity is described from an individual buried in a settlement pit at an archaeological site Třebčín in Moravia dating from the period of the Great Moravian (AD 800-950). Macroscopic and radiological examinations are employed to diagnose pathological leasions on the skeleton of an adult female. Female was probably affected by a haematogenous form of acute osteomyelitis from early neonatal age., Anna Pankowská., and Obsahuje bibliografii
Unikátní vakcína pro léčbu infekčních onemocnění, historicky první zdokumentování vývoje zubu, které může pomoci v boji proti rakovině, revoluční objev organismu bez mitochondrií neboli „buněčných elektráren“ -i takové jsou aktuální výsledky vědeckých týmů z centra BIOCEV, které za účasti významných hostů zahájilo 16. června 2016 plný provoz., A unique vaccine to treat infectious diseases, tooth development documented the first time in history that might help fight cancer and the revolutionary discovery of an organism without mitochondria, referred to as “cell power plants”. These are some of the current results from the BIOCEV research teams. The centre’s full operation was officially launched on June 16, 2016 in the presence of Czech and foreign guests from different areas of science and politics. The Biotechnology and Biomedicine Centre of the Academy of Sciences and Charles University in Vestec (BIOCEV) was established with substantial financial aid from the European Union. By 2020, 400 researchers and 200 master’s degree as well as postgraduate students are expected to work there. As of today, 56 research groups under five synergic research programmes are focused on obtaining more detailed understanding of organisms at the molecular level. Their results are oriented towards applied research and the development of new medical procedures to combat severe health problems., Isd., and Autor je podepsaný šifrou Isd.
