Efficiency of different doses of mineral fertilizers for winter wheat

The regulated use of various types of mineral fertilizers in crop production directly affects the size and harvest quality of field crops, in particular winter wheat, which makes high demands on the diet. Even the most fertile soils, like chernozems, can be depleted over the years, with their constant use for crops and intense anthropogenic impact. The article presents the issues of mineral nutrition of varieties of winter soft wheat in the soil and climatic conditions of the Republic of Adygea. In the course of the research, it has been found that a high level of increase in the yield of winter wheat grain when using various doses of mineral fertilizer can be ensured due to the formation of timely and friendly seedlings of the culture, an increase in the total tilling capacity – 576 pcs/m2 and the productive one – 313 pcs/m2, in the intensity of accumulation of dry biomass by plants – 328 g/100 plants, in the «full ripeness» phase, ear lengthening – 7,1 cm and an increase in the amount of grain in it – 29 pcs., an increase in the mass of 1000 grains – 45,0 and other quality indicators. On average, according to the experience, the maximum yield of winter wheat is formed due to the introduction of a dose of N90P90K60 mineral fertilizer, where it was 4,60 t /ha for Goryanka and 4,74 t /ha for Maykopchanka. According to the analysis of the grain (protein content, gluten) and flour quality (strength of flour, volumetric yield of bread) of the studied wheat varieties, higher indicators were obtained when using the dose of N90P90K60 mineral fertilizer. Despite the high yield on this option, from an economic point of view, the most effective one was the option with the introduction of N30P30K30 fertilizers. When comparing the most optimal options for the two varieties (application of a dose of N30P30K30 fertilizers), the production of the Maykopchanka variety was more efficient

The Evolution of Artificial Intelligence and the Possibility of its Application in Cyber Games

Artificial intelligence, as a separate field of research, is currently experiencing a boom - new methods of machine learning and hardware are emerging and improving, and the results achieved change the life of society. Machine translation, handwriting recognition, speech recognition are changing our reality. The work of creating unmanned vehicles, voice assistants and other devices using these technologies is in an active process. The article examines the historical context of the artificial intelligence development, it evaluates the possibilities of its introduction into cyber games, as a safe and effective platform for testing new methods of machine learning. The promotion of such projects can increase the reputation of development companies, ensure increased user confidence in other products and, with a competent marketing strategy, cause a significant public resonance among video game fans, providing the developer with economic profit

Hippocampal CA1 gamma power predicts the precision of spatial memory judgments.

The hippocampus plays a critical role in spatial memory. However, the exact neural mechanisms underlying high-fidelity spatial memory representations are unknown. We report findings from presurgical epilepsy patients with bilateral hippocampal depth electrodes performing an object-location memory task that provided a broad range of spatial memory precision. During encoding, patients were shown a series of objects along the circumference of an invisible circle. At test, the same objects were shown at the top of the circle (0°), and patients used a dial to move the object to its location shown during encoding. Angular error between the correct location and the indicated location was recorded as a continuous measure of performance. By registering pre- and postimplantation MRI scans, we were able to localize the electrodes to specific hippocampal subfields. We found a correlation between increased gamma power, thought to reflect local excitatory activity, and the precision of spatial memory retrieval in hippocampal CA1 electrodes. Additionally, we found a similar relationship between gamma power and memory precision in the dorsolateral prefrontal cortex and a directional relationship between activity in this region and in the CA1, suggesting that the dorsolateral prefrontal cortex is involved in postretrieval processing. These results indicate that local processing in hippocampal CA1 and dorsolateral prefrontal cortex supports high-fidelity spatial memory representations

Multidrug-resistance and presence of class 1 integrons in clinical isolates of Salmonella enterica serotype Enteritidis, circulating in Armenia

Abstract. The aim of this work was detection of class 1 integrons and their contribution to the antimicrobial resistance phenotypes in strains of   subspecies enterica serotype Enteritidis. S. Enteritidis strains (n = 29) were isolated from patients with salmonellosis at “Nork” Clinical Hospital of Infectious Diseases, Yerevan, Republic of Armenia. High prevalence of multi-drug resistance (MDR) phenotypes was revealed and isolates with MDR phenotypes which are rare in the S. Enteritidis serotype were observed. Class 1 integrons were detected in 27,6% of isolates, with the prevalence of a variable region of 1000 bp. Occurrence of the MDR phenotype was more frequent in integron-positive isolates compared to integron-negative isolates of S. Enteritidis. Further studies are necessary to reveal the genetic background of MDR phenotypes and to estimate the genetic kinship among the isolates. Our results suggest a rapid and large-scale penetration of antibiotic resistance genes into populations of S. Enteritidis, which complicates infection control. More rigorous regulations should be imposed on antibiotic use, together with a vigilant epidemiological surveillance, to prevent the emergence and spread of MDR S. Enteritidis

Irritable Bowel Syndrome Onset after New Coronavirus Infection COVID-19

Aim. A psychometric comparison in patients with previous irritable bowel syndrome (IBS) vs. those with IBS presenting six months or later since COVID-19 infection.Materials and methods. The study included patients having had COVID-19 infection over 6 months ago and complying with Rome IV criteria (2016). The study cohort was 100 patients with gastrointestinal symptoms. Fourteen patients (cohort 1) complied with the IBS criteria, 5 males and 9 females. A comparison cohort was 40 patients with IBS verified prior to the COVID-19 pandemic (cohort 2), 12 males and 28 females. Data were obtained from the SIPSITEST 9.0 DBMS resource. The control cohort comprised 50 healthy respondents (cohort 3), 23 males and 27 females. Depression was scored with the Beck Inventory, anxiety — with Spielberger—Khanin (adapted STAI) questionnaire; childhood psychogeny has also been assessed.Results. In statistical analysis of cohort 1, mean depression, personality and reactive anxiety scores were 11 ± 2.27, 43.8 ± 1.93 and 46.7 ± 2.05, respectively. Mean values in cohort 2: personality anxiety 47.3 ± 1.46, reactive anxiety 50.7 ± 1.96 and depression 12.85 ± 1.13. With childhood psychogeny, positive answers to at least one question were reported in 9 of 14 (65%) patients in cohort 1 and 33 (82.5%) — in cohort 2. No study inter-cohort differences have been observed for personality or reactive anxiety and depression, nor for the history of childhood psychogeny.Conclusion. The new coronavirus infection entails postinfectious IBS in 6 months after COVID-19
