The need for unified approaches to determining the phenological phase of a reliable indicator vegetative index is one critical problems early forecasting crop yields using satellite monitoring. Several works domestic and foreign researchers formulate different estimates correlation relationship between NDVI yield. This study aimed obtain predictive models product winter wheat spring barley indi...

The paper presents the results of analysis performed to reveal chemical features life forms aboveground mass plant species predominating in geosystems Onon-Argun steppe on Kharanor transect testing area. On basis biogeochemical studies plants, possibility analyzing patterns geosystems’ functioning has been revealed. choice area was determined by landscape structure, forming a landscape-ecologic...

Rheumatoid factor (RF) antibodies are directed against the Fc part of IgG. Raised levels are found in most patients with rheumatoid arthritis (RA), but sometimes also in other connective tissue diseases, chronic infections, malignancy, and even in a small proportion of apparently healthy subjects.' Rheumatoid factor has mostly been measured by agglutination techniques, such as the RoseWaaler an...

An attempt is made to summarize the different ways of modelling the anisotropy of a polycrystalline material. At the single crystal level, the formulation based on Schmid law or viscoplasticity shows clearly the microscopic anisotropy due to the hardening and the orientation changes. It is also shown how viscoplasticity leads to a unique slip system activity irrespectively of the rate sensitivi...

The Swift test was originally proposed as a formability test to reproduce the conditions observed in deep drawing operations. This test consists on forming a cylindrical cup from a circular blank, using a flat bottom cylindrical punch and has been extensively studied using both analytical and numerical methods. This test can also be combined with the Demeri test, which consists in cutting a rin...

The current study has been carried out to determine the effect of mineral and organic fertilizers, as well a growth regulator on productivity promising winter durum wheat varieties, under irrigation conditions meadow-chestnut heavy loamy soil in Terek-Sulak subprovince Republic Dagestan. In 2019–2021 there were laid two trials experimental plot. first case, studied four variants fertilizers var...

The article presents the results of research on peculiarities spelled yield formation and grain quality depending humate plant growth regulator use in conditions unstable moisture Forest Steppe Ukraine. purpose was to identify influence elements technology growing varieties productivity grain. During 2019–2022, conducted at experimental field educational production centre Bila Tserkva National ...

The levels of 26 mycotoxins were determined in 147 samples of the grain of cereals cultivated in five regions of Poland during the 2014 growing season. The HPLC-HRMS (time-of-flight) analytical technique was used. An analytical procedure to simultaneously determine 26 mycotoxins in grain was developed, tested and verified. Samples from eastern and southern Poland were more contaminated with myc...
