The importance of the yield components of the spring durum wheat varieties from Russia and Kazakhstan
Published 2020-10-01“…Field trials were carried out for three years (2015, 2016, 2018); the accounting area of the plots was 10.0 m2, with threefold repetition, with random plot placement; the sheaves for laboratory analysis were taken from each repetition (sampling area of 0.63 m2). Using the methods of correlation and path analysis, there has been established a significant correlation between variation of yield and such traits as economic coefficient (К.хозР), nature weight (H), 1000 grain weight (M1000), sterility of heads in the cenosis (Ст), number of grains per spikelet (ЧЗКК) and number of days before tillering (КДК).…”

Published 2025-08-01“…Because of the considerable spectral overlap, six mathematical spectrophotometric approaches were applied, including ratio derivative, ratio difference, mean centering of ratio spectra, area under the curve, Q-analysis, and bivariate calibration, to allow accurate interference-free determination without preliminary separation. The proposed methods were validated as per ICH guidelines, demonstrating excellent linearity over the concentration ranges of 1–15 µg/mL for RDV and 1–10 µg/mL for MFX, with correlation coefficients exceeding 0.999. …”

Improved RFID anti-collision algorithm based on ALOHA Abstract:In order to solve the problem of low efficiency of electronic tag identification in RFID system,a new ALOHA anti-collision algorithm was presented.In this algorithm,the coefficients of the tag estimation were automatically changed by using the dynamic adjustment method,which made the number of tag estimation could be dynamic changed with the number of identified tags,then the number of tags to be identified was estimated.And for the frame length adjustment,it could be determined by the relationship between the length of the frame and the tag number according to the estimated number of tags.With the tool of MATLAB,the results show that the proposed algorithm can significantly improve the throughput and stability of the system.
