Evgeny Nikolaevich Sedov: a leading breeder of pome fruit crops in Russia
No full textAcad. Evgeny Nikolaevich Sedov, Doctor of Agricultural Sciences, Full Member of the Russian Academy of Agricultural Sciences, Full Member of the Russian Academy of Sciences, Professor, Scientist Emeritus, is an outstanding researcher and breeder, author of 90 apple and pear cultivars, founder of a scientific school specializing on priority trends in pome fruit breeding: – development of adaptable triploid apple cultivars with regular fruiting, high marketability of fruits, and increased self-fertility; – development of apple cultivars immune or highly resistant to scab; – development of triploid apple cultivars with immunity to scab; – development of columnar apple cultivars for super-intensive orchards and main technology elements for their cultivation; – development of apple cultivars with improved biochemical composition of fruits with higher content of ascorbic acid (vitamin C) and Р-active substances (vitamin Р)

No full textThe applicability of the Sedov-Taylor scaling during material removal of metals and oxide layers with pulsed CO2 and excimer laser radiation
No full textS.980-989For the removal of material with pulsed laser radiation the distance travelled by the shock or blast wave and the amount of energy released in the plasma state due to the absorption of laser radiation are determined experimentally and theoretically. The distance travelled by the blast wave is detected by schlieren photography, the released energy by monitoring the transmitted laser radiation during the removal process. The theoretical evaluation is performed by numerical simulation using a model incorporating the laser-induced vaporization process and the dynamics of the plasma state. The results obtained from the experiments and the model are compared with that of the Sedov-Taylor scaling. The removal of the oxide layer from austenitic steel is investigated with C02 laser radiation produced by a TEA and a high-power C02 laser device. For the TEA laser with fluences of 5 and 10 J cm(exp -2) 50-80 per cent of the pulse energy is released into the plasma state and the Sedov-Taylor scalin g describes the distance travelled by the blast wave in agreement with data from the experiments and the simulation. For the high-power C02 laser with a fluence of 50 J cm(exp -2), 6 per cent of the pulse energy is released into the plasma state and the Sedov-Taylor scaling does not describe the data of the simulation. The process of removal of copper and aluminium material is simulated for excimer laser radiation with fluences of 15 and 30 J cm(exp -2). For copper 15-30 per cent of the pulse energy is released into the plasma state and the Sedov-Taylor scaling is applicable. For aluminium, less than 2 per cent of the pulse energy is released into the plasma state and the Sedov-Taylor scaling is only applicable for the higher fluence.3

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
