Charging Station Allocation for Electric Vehicle Network Using Stochastic Modeling and Grey Wolf Optimization
Authors: Shabbar Rawan , Kasasbeh Anemone , Ahmed Mohamed M.
Published: March 2021

Optimal placement of Charging stations (CSs) and infrastructure planning are one of the most critical challenges that face the Electric Vehicles (EV) industry nowadays. A variety of approaches have been proposed to address the problem of demand uncertainty versus the optimal number of CSs required to build the EV infrastructure. In this paper, a Markov-chain network model is designed to study the estimated demand on a CS by using the birth and death process model. An investigation on the desired number of electric sockets in each CS and the average number of electric vehicles in both queue and waiting times is presented. Furthermore, a CS allocation algorithm based on the Markov-chain model is proposed. Grey Wolf Optimization (GWO) algorithm is used to select the best CS locations with the objective of maximizing the net profit under both budget and routing constraints. Additionally, the model was applied to Washington D.C. transportation network. Experimental results have shown that to achieve the highest net profit, Level 2 chargers need to be installed in low demand areas of infrastructure implementation. On the other hand, Level 3 chargers attain higher net profit when the number of EVs increases in the transportation network or/and in locations with high charging demands.

Published: March 2021

The existing literature evidences the potential of the e-learning methodology, although some call it into question. Our study aimed to analyse the real scope of applying this methodology type to a lockdown situation like that caused by COVID-19. It could provide the scientific and educational community with useful novel information on e-learning and its real adequacy for schools in pre-university educational stages. This qualitative study was designed using questionnaires with open-ended questions for students and semistructured interviews for teachers, management board members, and families of students of Primary and Secondary Education. The scripts of data collection tools were made ad hoc. The thematic analysis was carried out in accordance with the study dimensions by relating the access and use of technological resources in classrooms, implementing the e-learning methodology during face-to-face teaching, and finally knowing the effects of its application during remote teaching in the lockdown situation. The results clearly show a need to adapt and adjust the implementation of this methodology by considering not only its specificities, but also a combination of e-learning and traditional teaching methodologies can help to introduce information and communication technologies (ICT) into classrooms. To conclude, including such a methodology in the educational context can be argued for, provided that specific training is received to allow the potential of both online and traditional teaching to be leveraged.
Green Synthesis of Ag-Au Bimetallic Nanocomposites Using Waste Tea Leaves Extract for Degradation Congo Red and 4-Nitrophenol
Authors: Kang Chun-Won , Kolya Haradhan
Published: March 2021

A sustainable supply of pure water is a great challenge in most developing and third-world countries. Nanomaterial-based technology offers technological development for wastewater purification. Nanocatalysis hydrogenation of nitroarene and dye molecules is a hot model in many research fields. Herein, we report eco-friendly and facile technology to synthesize Ag-Au bimetallic nanocomposites. The synthesized nanocomposites are characterized by ultraviolet–visible spectroscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy and high-resolution transmission electron microscopy. The synthesized nanocomposite can efficiently degrade Congo red and 4-nitrophenol in water and in the presence of sodium borohydride. The results show that it degrades Congo red and 4-nitrophenol entirely within 6 and 7 min, respectively. These results could be useful for the green synthesis of Ag-Au bimetallic nanocomposites and help to remove organic dye molecules and nitroaromatics from wastewater.

Authors: Gambelli Danilo , Solfanelli Francesco , Orsini Stefano , Zanoli Raffaele
Published: March 2021

Given the increasing complexity of the agro-food sector, the analysis of financial performance alone may not be sufficient to assess the economic sustainability of farmers. This paper presents a practical method to measure the performance of farm businesses by combining the Balanced Scorecard (BSC) theoretical framework and Importance–Performance Analysis (IPA). The proposed model of Business Performance Indicators (BPI) measurement allows identification and validation of the indicators that consistently measure the latent dimension of the BSC framework while allowing identification Buin of the BPI areas where farm businesses need to concentrate their efforts to assure economic sustainability. The method was applied to small ruminant farm businesses across Europe through visits and interviews. The case study application showed that the model could help measure the performance of small farms while allowing detection of the areas of fragility and intervention. The case study results showed that finance and internal business management were the most relevant farmers’ weaknesses, alongside low priority given to innovation. In conclusion, to prevent the potential long-term decline of the sector, the study provided evidence for policy changes to support the farmers’ innovation potential and a higher level of integration in the supply chain.
Integrating a High-Reliability Multicriteria Trust Evaluation Model with Task Role-Based Access Control for Cloud Services
Authors: Alshammari Salah T. , Albeshri Aiiad , Alsubhi Khalid
Published: March 2021

Cloud data storage is revolutionary because it eliminates the need for additional hardware, which is often costly, inconvenient, and requires additional space. Cloud data storage allows data owners to store large amounts of data in a flexible way and at low cost. The number of online cloud storage services and their consumers has therefore increased dramatically. However, ensuring the privacy and security of data on a digital platform is often a challenge. A cryptographic task-role-based access control (T-RBAC) approach can be used to protect data privacy. This approach ensures the accessibility of data for authorized consumers and keeps it safe from unauthorized consumers. However, this type of cryptographic approach does not address the issue of trust. In this paper, we propose a comprehensive trust model integrated with a cryptographic T-RBAC to enhance the privacy and security of data stored in cloud storage systems, and suggests that trust models involve inheritance and hierarchy in the roles and tasks of trustworthiness evaluation, where this study aims to identify the most feasible solution for the trust issue in T-RBAC approaches. Risk evaluations regarding other possible flaws of the design are also performed. The proposed design can decrease risk by providing high security for cloud storage systems and improve the quality of decisions of cloud operators and data owners.
A Review in Ermakov Systems and Their Symmetries
Authors: Cerveró Jose M. , Estévez Pilar G.
Published: March 2021

A review of the mathematical and physical aspects of the Ermakov systems is presented. The main properties of Lie algebra invariants are extensively used. The two and tridimensional Ermakov systems are fully analyzed and the correspondent invariants found. Then, we go over quantization with special emphasis in the two dimensional case. An application to Nonlinear Optics is hereby developed. We also treat the so-called “one dimensional” case, which is easily solved in the classical case but offers special interest in the quantum realm, where one can find exactly the Feynman propagator. We finish with the stationary phase approximation which contains also some interesting features when compared with the exact solution. Some prospects for future research are also discussed.
In-Vitro and In-Silico Assessment of Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Film-Forming Foam (AFFF) Binding to Human Serum Albumin
Authors: Li Wenting , Hu Yuhong , Bischel Heather N.
Published: March 2021

Drinking water contaminated by fluorosurfactant-based aqueous film-forming foams (AFFF) is a source of human exposure to poly- and perfluoroalkyl substances (PFAS). However, assessment of bioaccumulation potentials of diverse PFAS in commercial products such as AFFF have been insufficient and challenging, especially due to a lack of analytical standards. Here we explore the value of suspect screening, equilibrium dialysis, and molecular-docking simulations to identify potentially bioaccumulative PFAS. We exposed human serum albumin (HSA) protein to dilutions of a legacy AFFF produced by 3M in 1999 using equilibrium dialysis and screened in-vitro protein-binding affinities using high-resolution mass spectrometry (HRMS). Through suspect screening, we identified 32 PFAS and 18 hydrocarbon surfactants in the AFFF that bound to HSA. Quantification of noncovalent association constants for 26 PFAS standards confirmed that many PFAS, including the short-chain perfluoropropane sulfonic acid (log Ka= 4.1 ± 0.2 M−1), exhibit strong binding affinities with HSA. At least five PFAS in AFFF (including three PFAS with less than five perfluorocarbons) remained bound to the precipitated HSA pellet after extensive solvent washing—an indication of high PFAS binding potential. Three PFAS (PFBS, PFOS, and PFOA) were confirmed in the protein pellet with analytical standards and quantified after acid digestion—this sample fraction accounted for 5 to 20% of each compound mass in the sample. We calculated pseudo-bioconcentration factors (BCFpseudo) for PFAS that suspect screening flagged as noncovalently bound or potentially covalently bound. Most PFAS exhibiting high BCFpseudo, especially those with seven perfluorocarbons, contained a carboxylic acid or a sulfonic acid. Finally, we used molecular docking to simulate HSA binding affinities for 62 ligands (26 PFAS targets, 18 PFAS qualified in AFFF, and 18 hydrocarbon surfactants qualified in AFFF). We found that molecular docking can effectively separate HSA-binding and -nonbinding compounds in AFFF. In-vitro and in-silico approaches described in this study provide replicable, high-throughput workflows for assessing bioaccumulation potentials of diverse PFAS in commercial products.
High-Throughput Screening of Psychotropic Compounds: Impacts on Swimming Behaviours in Artemia franciscana
Authors: Kohler Shanelle , Parker Matthew , Ford Alex
Published: March 2021

Animal behaviour is becoming increasingly popular as an endpoint in ecotoxicology due to its increased sensitivity and speed compared to traditional endpoints. However, the widespread use of animal behaviours in environmental risk assessment is currently hindered by a lack of optimisation and standardisation of behavioural assays for model species. In this study, assays to assess swimming speed were developed for a model crustacean species, the brine shrimp Artemia franciscana. Preliminary works were performed to determine optimal arena size for this species, and weather lux used in the experiments had an impact on the animals phototactic response. Swimming speed was significantly lower in the smallest arena, whilst no difference was observed between the two larger arenas, suggesting that the small arena was limiting swimming ability. No significant difference was observed in attraction to light between high and low light intensities. Arena size had a significant impact on phototaxis behaviours. Large arenas resulted in animals spending more time in the light side of the arena compared to medium and small, irrespective of light intensity. The swimming speed assay was then used to expose specimens to a range of psychotropic compounds with varying modes of action. Results indicate that swimming speed provides a valid measure of the impacts of behaviour modulating compounds on A. franciscana. The psychotropic compounds tested varied in their impacts on animal behaviour. Fluoxetine resulted in increased swimming speed as has been found in other crustacean species, whilst oxazepam, venlafaxine and amitriptyline had no significant impacts on the behaviours measured. The results from this study suggest a simple, fast, high throughput assay for A. franciscana and gains insight on the impacts of a range of psychotropic compounds on the swimming behaviours of a model crustacean species used in ecotoxicology studies.

Charcoal- or wood-cooked chicken is a street-vended food in Burkina Faso. In this study, 15 samples of flamed chicken and 13 samples of braised chicken were analyzed for 15 priority polycyclic aromatic hydrocarbons (PAHs) with a high-performance liquid chromatography-fluorescence detector. A face-to-face survey was conducted to assess the consumption profiles of 300 men and 300 women. The health risk was assessed based on the margin of exposure (MOE) principle. BaP (14.95–1.75 μg/kg) and 4PAHs (BaP + Chr + BaA + BbF) (78.46–15.14 μg/kg) were eight and five times more abundant at the median level in flamed chickens than in braised ones, respectively. The contents of BaP and 4PAHs in all flamed chicken samples were above the limits set by the European Commission against 23% for both in braised chickens. Women had the highest maximum daily consumption of both braised (39.65 g/day) and flamed chickens (105.06 g/day). At the estimated maximum level of consumption, women were respectively 3.64 (flamed chicken) and 1.62 (braised chicken) times more exposed to BaP and 4PAHs than men. MOE values ranged between 8140 and 9591 for men and between 2232 and 2629 for women at the maximum level of consumption of flamed chickens, indicating a slight potential carcinogenic risk.

Published: March 2021

The internal microbiome of common cat and dog fleas was studied for DNA evidence of pathogenic bacteria. Fleas were grouped in pools by parasitized animal. DNA was extracted and investigated with 16S metagenomics for medically relevant (MR) bacteria, based on the definitions of the International Statistical Classification of Diseases and Related Health Problems (WHO). The MR bacterial species totaled 40, were found in 60% of flea-pools (N = 100), and included Acinetobacterbaumannii, Bacteroidesfragilis, Clostridiumperfringens, Enterococcusfaecalis, E. mundtii, Fusobacteriumnucleatum, Haemophilusaegyptius, Kingellakingae, Klebsiellapneumoniae, Leptotrichiabuccalis, L. hofstadii, Moraxellalacunata, Pasteurellamultocida, Propionibacteriumacnes, P. propionicum, Proteusmirabilis, Pseudomonasaeruginosa, Rickettsiaaustralis, R. hoogstraalii, Salmonellaenterica, and various Bartonella, Staphylococcus, and Streptococcus species. B. henselae (p = 0.004) and B. clarridgeiae (p = 0.006) occurred more frequently in fleas from cats, whereas Rickettsiahoogstraalii (p = 0.031) and Propionibacteriumacnes (p = 0.029) had a preference in fleas from stray animals. Most of the discovered MR species can form biofilm, and human exposure may theoretically occur through the flea-host interface. The fitness of these pathogenic bacteria to cause infection and the potential role of fleas in the transmission of a broad range of diseases should be further investigated.
Resurrection of a Viral Internal Ribosome Entry Site from a 700 Year Old Ancient Northwest Territories Cripavirus
Authors: Wang Xinying , Vlok Marli , Flibotte Stephane , Jan Eric
Published: March 2021

The dicistrovirus intergenic region internal ribosome entry site (IGR IRES) uses an unprecedented, streamlined mechanism whereby the IRES adopts a triple-pseudoknot (PK) structure to directly bind to the conserved core of the ribosome and drive translation from a non-AUG codon. The origin of this IRES mechanism is not known. Previously, a partial fragment of a divergent dicistrovirus RNA genome, named ancient Northwest territories cripavirus (aNCV), was extracted from 700-year-old caribou feces trapped in a subarctic ice patch. The aNCV IGR sequence adopts a secondary structure similar to contemporary IGR IRES structures, however, there are subtle differences including 105 nucleotides upstream of the IRES of unknown function. Using filter binding assays, we showed that the aNCV IRES could bind to purified ribosomes, and toeprinting analysis pinpointed the start site at a GCU alanine codon adjacent to PKI. Using a bicistronic reporter RNA, the aNCV IGR can direct translation in vitro in a PKI-dependent manner. Lastly, a chimeric infectious clone swapping in the aNCV IRES supported translation and virus infection. The characterization and resurrection of a functional IGR IRES from a divergent 700-year-old virus provides a historical framework for the importance of this viral translational mechanism.
SARS-CoV-2 Infections in Animals: Reservoirs for Reverse Zoonosis and Models for Study

Published: March 2021

The recent SARS-CoV-2 pandemic has brought many questions over the origin of the virus, the threat it poses to animals both in the wild and captivity, and the risks of a permanent viral reservoir developing in animals. Animal experiments have shown that a variety of animals can become infected with the virus. While coronaviruses have been known to infect animals for decades, the true intermediate host of the virus has not been identified, with no cases of SARS-CoV-2 in wild animals. The screening of wild, farmed, and domesticated animals is necessary to help us understand the virus and its origins and prevent future outbreaks of both COVID-19 and other diseases. There is intriguing evidence that farmed mink infections (acquired from humans) have led to infection of other farm workers in turn, with a recent outbreak of a mink variant in humans in Denmark. A thorough examination of the current knowledge and evidence of the ability of SARS-CoV-2 to infect different animal species is therefore vital to evaluate the threat of animal to human transmission and reverse zoonosis.

Since the emergence of coronavirus disease (COVID-19) in late 2019, domestic cats have been demonstrated to be susceptible to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) under natural and experimental conditions. As pet cats often live in very close contact with their owners, it is essential to investigate SARS-CoV-2 infections in cats in a One-Health context. This study reports the first SARS-CoV-2 infection in a cat in a COVID-19-affected household in Switzerland. The cat (Cat 1) demonstrated signs of an upper respiratory tract infection, including sneezing, inappetence, and apathy, while the cohabiting cat (Cat 2) remained asymptomatic. Nasal, oral, fecal, fur, and environmental swab samples were collected twice from both cats and analyzed by RT-qPCR for the presence of SARS-CoV-2 viral RNA. Both nasal swabs from Cat 1 tested positive. In addition, the first oral swab from Cat 2 and fur and bedding swabs from both cats were RT-qPCR positive. The fecal swabs tested negative. The infection of Cat 1 was confirmed by positive SARS-CoV-2 S1 receptor binding domain (RBD) antibody testing and neutralizing activity in a surrogate assay. The viral genome sequence from Cat 1, obtained by next generation sequencing, showed the closest relation to a human sequence from the B.1.1.39 lineage, with one single nucleotide polymorphism (SNP) difference. This study demonstrates not only SARS-CoV-2 infection of a cat from a COVID-19-affected household but also contamination of the cats’ fur and bed with viral RNA. Our results are important to create awareness that SARS-CoV-2 infected people should observe hygienic measures to avoid infection and contamination of animal cohabitants.

Universal vaccines can be prepared with antigens common to different pathogens. In this regard, the glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a common virulence factor among pathogenic bacteria of the genera Listeria, Mycobacterium and Streptococcus. Their N-terminal 22 amino acid peptides, GAPDH-L1 (Listeria), GAPDH-M1 (Mycobacterium) and GAPDH-S1 (Streptococcus), share 95–98.55% sequence homology, biochemical and MHC binding abilities and, therefore, are good candidates for universal vaccine designs. Here, we used dendritic cells (DC) as vaccine platforms to test GAPDH epitopes that conferred protection against Listeria monocytogenes, Mycobacterium marinum or Streptococcus pneumoniae in our search of epitopes for universal vaccines. DC loaded with GAPDH-L1, GAPDH-M1 or GAPDH-S1 peptides show high immunogenicity measured by the cellular DTH responses in mice, lacked toxicity and were capable of cross-protection immunity against mice infections with each one of the pathogens. Vaccine efficiency correlated with high titers of anti-GAPDH-L1 antibodies in sera of vaccinated mice, a Th1 cytokine pattern and high frequencies of GAPDH-L1-specific CD4+ and CD8+ T cells and IFN-γ producers in the spleens. We concluded that GAPDH-L1 peptide was the best epitope for universal vaccines in the Listeria, Mycobacterium or Streptococcus taxonomic groups, whose pathogenic strains caused relevant morbidities in adults and especially in the elderly.
An Intelligent Adaptive Neural Network Controller for a Direct Torque Controlled eCAR Propulsion System
Authors: Banda Gururaj , Kolli Sri Gowri
Published: March 2021

This article deals with an intelligent adaptive neural network (ANN) controller for a direct torque controlled (DTC) electric vehicle (EV) propulsion system. With the realization of artificial intelligence (AI) conferred adaptive controllers, the torque control of an electric car (eCAR) propulsion motor can be achieved by estimating the stator reference flux voltage used to synthesize the space vector pulse width modulation (SVPWM) for a DTC scheme. The proposed ANN tool optimizes the parameters of a proportional integral (PI) controller with real-time data and offers splendid dynamic stability. The response of an ANN controller is examined over standard drive cycles to validate the performance of an eCAR in terms of drive range and energy efficiency using MATLAB simulation software.

Published: March 2021

In this paper, the major factors that affect the performance of wireless power transfer systems, such as coil inner radius and coil number of turns, are discussed. A comparison of three coil shapes covering the coreless case, the case with ferrite, and the case with ferrite and aluminum is also carried out. Another comparison is proposed by addressing the combination of different coil shapes in the wireless power transfer (WPT)system. The analysis covers the coupling coefficient, the mutual inductance, and the self-inductance. Due to the complexity of calculating these parameters, the finite element analysis (FEA) method is adopted by using the Ansys Maxwell software. An introduction to the typical WPT system for electric vehicle charging is also presented.

Investigating the limits of legal anti-racist struggle
Authors: Sebastiani Luca
Published: March 2021

This paper focuses on the articulation between knowledge(s), practices and devices emerging from the Spanish policy framework against racial or ethnic discrimination. Based on the fieldwork done in Madrid and other Spanish localisations during 2019, I delve into the problematisations of racism fostered by situated actors (both institutional and “non-governmental”) that participate in this space, focusing on how such problematisations affect the legal notions being adopted and the “daily” legal struggle against discrimination. By addressing three specific situations, I point to the following results: a) a prevailing individualist and abstract notion of equality/discrimination, which ends up underestimating the collective dimension of racism and is traversed by “institutional whiteness”; b) the denial/downplaying of institutional/structural/governmental racism; c) the blurring of anti-racism within a legalist approach, not able to deal with the social, political, and historical dimensions of racial discrimination.
Effect of the Chaotic Crossover Operator on Breeding Swarms Algorithm
Authors: Demirci Hüseyin , Yurtay Nilüfer
Published: March 2021

In this paper we present effect of the chaotic crossover operator with different chaotic maps on the metaheuristic search algorithm Breeding Swarms algorithm which is the Particle Swarm Optimization’s one of the genetic algorithm hybrid form. Some of the many optimization problems could have too many local extrema. Most of the time optimization algorithms could stuck on these extrema therefore these algorithms could have trouble with finding global extremum. To avoiding local extrema and conduct better search on search space, a chaotic number generator is used on Breeding Swarms algorithm’s most of the random procedures. To test efficiency and randomness of the chaotic crossover operator, different chaotic maps are used on the Breeding Swarm algorithm. Test and performance evaluations are conducted on Multimodal and unimodal benchmark functions. This new approach showed us that modified Breeding Swarms algorithm yielded slightly better results than Particle Swarm Optimization and original Breeding Swarms algorithms on tested benchmark functions.

The article has already analyzed the problem of ensuring the competitiveness of vegetable products in the European market. We have already revealed the need to integrate EU quality standards into Ukrainian legislation. It was determined that one of the mechanisms for increasing the competitiveness of vegetable products is the harmonization of national quality standards with European ones. The aim of work - to reveal the existing problems regarding the quality of vegetable products, to justify the need to integrate EU standards into Ukrainian legislation, to give a comparative description of the quality standards of fresh vegetables in Ukraine and the EU. The quality standards for fresh vegetables in Ukraine and the EU countries are now being analyzed in the context of our country's aspiration to join this organization. In Ukraine, the quality of fresh vegetables is established by national standards (DSTU), as well as harmonized with European ones (DSTU UNECE FFV). Presented were the comparative characteristics of the quality requirements for fresh cabbage, carrots and onions. On the basis of the analysis, obvious differences between national standards and those harmonized with European quality standards for vegetables were outlined.
Conclusions. Consequently, the harmonization of national quality standards with European ones is one of the mechanisms for increasing the competitiveness of Ukrainian vegetable products in the European market. From the examples given earlier, common and opposite features of the classification of product standards in Ukraine and the EU countries, an analysis of domestic and foreign regulatory and technical documentation for fresh vegetables, it was found that the quality of vegetable products was assessed according to the same organoleptic properties (appearance, shape requirements, dimensions products, color, taste, smell), as well as physicochemical (content of harmful substances), contained requirements for packaging, labeling, transportation and storage, but there were differences in the norms of individual indicators. In addition, the EU marketing standards do not contain storage requirements, as it is mandatory for the manufacturer/seller. Ukrainian standards for fresh white cabbage, carrots and onions set maximum levels for heavy metals like lead, cadmium, mercury, copper, zinc. For EU producers, maximum levels of pollutants have been given in separate EU regulations.

Keywords: fresh vegetables, quality, harmonization, marketing standard, national standard, white cabbage, onion, carrots.

Published: March 2021

The article presents the results of the research conducted during the 2015–
2017 years. On the experimental field of the Department of Horticulture and Storage of V.V. Dokuchaev KNAU was determined the influence of the plant growth regulators on the formation of a marketable yield and the content of some components of the cauliflower hybrids chemical composition.
The early ripening hybrids of cauliflower Livingstone F1 and Kul F1 were studied. The Humisol-super, Vympel, and Megafol were taken for the study. The experience was a two-factor: factor A was the features of the hybrid, factor B was drug treatment. The repetition was four-fold. Field experiments were carried out according to generally accepted methods. The cauliflowers` soil preparation and the plant care were carried out according to the generally accepted recommendations.
Treatment with growth regulators was carried out by spraying plants during the growing season according to the manufacturers' recommendations. The first spraying was carried out after planting seedlings in the open ground; the subsequent spraying had been carried every 14 days. An option without treatment was taken as a control.
As a result of the studies, it was found that treatment of cauliflower plants with growth regulators during the growing season significantly affects the yield of hybrids. Over the years of research, the highest yield of the Livingston F1 hybrid was obtained with the Megafol treatment, – 12,9 t/ha (+1,6 t/ha to control). The highest yield of the Kul F1 hybrid was 13,4 t/ha (+1,0 t/ha to control) during Humisol-super treatment.
It has been proved that the usage of the growth regulators influenced the physical indicators of the commercial yield of hybrids. During the 2015–2017 years, the average weight of cauliflower heads increased by 2,1–11,8 % compared to the control, depending on the treatment. The Megafol had a greater effect on the hybrids. Plants` treatment with growth regulators increased the average volume of the hybrid head by 1,3–11,3 % compared to the control. In terms of influence on this indicator, Megafol and Humisol-super were the best drugs.
It has been established that plant growth regulators affect the components of the cauliflowers' heads' chemical composition. The Vympel and Megafol increased the dry matter content in the Kul F1 hybrid by 1,0 and 1,4 %, respectively, compared with the control. The treatment of plants with the Humisol-super increased the ascorbic acid content in the heads of the Livingston F1 hybrid by 4,3 % compared to the control.
It is recommended to apply the treatment of plants during the growing season with Humisol-super (1,5l/ha) and Megafol (2,3 l/ha) every 14 days to increase the yield and improve the physical parameters of cauliflower heads.

Published: March 2021

In increasing the yield and improving the quality of safflower products, the primary importance belongs to the agronomic requirements for cultivation, which are based on the biological and physiological characteristics of the culture. The aim of the research was to determine the economic efficiency of growing safflower varieties with the use of additional mineral nutrition and microbiological preparations. The research was conducted in 2017–2019 in the fields of the Institute of Oilseeds of NAAS.Safflower was sown in the first decade of April with a sowing rate of 240,000 similar seeds per hectare. The system of the main tillage: classical. As research factors were selected: varieties – Zhyvchyk and Dobrynya; application of mineral fertilizers – without fertilizers, N60P50 under the main cultivation, P50 – under the main cultivation + N60 – at sowing; application of growth regulators – control (without treatment), Rost-concentrate + Chelatin oil, Chelatin forte + Chelatin mono bor, Chelatin mono bor + Chelatin phosphorus-potassium, Chelatin phosphorus-potassium + Chelatin multimix + Chelatin mono bor. Technical and economic evaluation of safflower cultivation with the use of additional mineral nutrition and microbiological preparations was performed using conventional methods. As a result of our three-year research, the influence of additional mineral nutrition and the use of microbiological preparations on the yield of safflower varieties Zhyvchyk and Dobrynya was established. The highest yields of safflower cultivar Zhyvchyk – 1.71 and 1.70 t/ha and Dobrynya cultivar – 1.84 and 1.85 t/ha were obtained against the background of mineral fertilizers at a dose of N60P50 under the main tillage with the use of Rost-concentrate + Chelatin oil and Chelatine mono bor + Chelatin phosphorus-potassium. The largest conditionally net profit – 22603 UAH/ha for the variety Zhyvchyk and 23837 UAH/ha for the variety Dobrynya was obtained on the background without mineral fertilizers with the use of drugs Chelatin mono bor + Chelatin phosphorus-potassium. The level of profitability, depending on the system of mineral fertilizers and the option of growth stimulants was: for the variety Zhyvchyk 143–524%, for the variety Dobrynya 161–551%. The highest yield of gross energy 38646 MJ/ha in the variety Zhyvchyk and 41509 MJ/ha in the variety Dobrynya was obtained against the background of the main application of N60P50 with treatment of crops with drugs Rost-concentrate + Chelatin oil. The highest indicators of energy coefficient for both varieties were in control (without fertilizers): in Zhyvchyk 3.0–3.1, in Dobrynуа 3.1–3.2.

Published: March 2021

The article analyzes the current state and improvement of elements of the technology of growing valuable forage and food crops, spring barley in Ukraine. It is noted that in recent years the area under large crops and the yield of this crop have decreased significantly. It is emphasized that further improvement of technologies should be focused on the transition to more use of biological agents to increase yields. Researchers have shown that the effectiveness of the use of humid preparations GK-6M, GK-4MK, GK-MK - on crops of spring barley Dokuchaivsky 15, due to foliar feeding of plants in the tiller ring phase. The main justification of the article is the results of field research conducted in 2015–2019. Maximum indicators, namely: increase in leaf area by 46–38 %, stem height by 8,3 cm; the number of grains in the ear – 4,8 pieces; ear lengths – 1,9 cm; mass of grain in the ear – 0,33 g; masses of 1000 grains – at 12,0 %; nature of grain – 34,9 g – was obtained by treating plants with humid preparation GK-6M. Foliar feeding of plants in the tiller ring phase with the studied drugs provided the largest increase in the yield of spring barley grain – 1,08 t/ha, provided the use of growth stimulant GK-6M. A slightly smaller effect of foliar fertilization of plants on the yield of spring barley was observed from the growth stimulator GK-4MK – the increase in grain yield was 0,83 t/ha and from the growth stimulant GK-MK – the increase in grain yield – 0,66 t/ha. The obtained increments are significant, mathematically proven. Further improvement of agrotechnologies due to wider use of biological means of increase of productivity and quality of production is offered.
