We compute a spectrum of parametric x-ray radiation inside crystal from bunch electrons, which is periodically modulated in density. consider that the electrons exiting an free-electron laser (XFEL) channel. demonstrate case resonance between frequency and modulation electron bunch, sequence strong quasimonochromatic pulses formed---superradiant emission (SPXE) with frequencies are multiples fr...

grapevine is one of the very important fruit crops in iran the fruit of which is used as table grape and/or raisins. in this study, some genetic parameters (phenotypic and genetic correlation, heritability and repeatability), of some important traits in table grape (date of ripening, weight, length and width of berry as well as attachment to cluster strength) were evaluated. results showed high...

In this study, it was aimed to determine the physical changes of seven different colored table grape varieties in samples taken at periods until ripening time. The cultivars used study are Alphonse Lavallée, Royal, Tekirdağ Çekirdeksizi, Michael Palieri, Karaerik, Bilecik İrikara and Horoz Karası. Grape were harvested for four weeks (20.08.2019, 27.08.2019, 02.09.2019 09.09.2019) every week app...

A comparative mathematical analysis of economically important ampelographic indicators was performed in 32 local, introduced and newly bred white wine vine varieties. It found that depending on the similarity remoteness values studied indicators, varieties are grouped into three generalized clusters. In first, characterized by a longer budding period relatively lower productivity. second, they ...
