Published: June 2021

Stabilisation of the functional properties of dispersed and compact metals, as well as the regulation of their reactivity, improvement of water-repellent, antifriction and anti-corrosion properties by creating the protective films on the surface is an urgent problem in relation to obtaining new materials. Previously, research conducted at REC “Nanotechnology” of the St. Petersburg Mining University proved that chemisorption of ethylhydridesiloxane vapours together with surfactants based on quaternary ammonium compounds has a beneficial effect on the water-repellent properties of metals. In order to obtain the physicochemical mechanism of the hydrophobisation of the surface of modified dispersed metals for the firsttime, the study of the electrophilic-nucleophilic properties of the active substances of the surface modifiers of metals was carried out using the methods of quantum-chemical modelling using HyperChem software package. The dipole moment, energy of the highest occupied and the lowest unoccupied molecular orbitals, electrophilic-nucleophilic properties were determined. The series of enhancement of ucleophilic/electrophilic properties and dipole moment for modifiers were obtained. The donor-acceptor properties, the differences in the characteristics of the molecules of alkamon, triamon, and hydrophobic silicone organic liquid were quantitatively and qualitatively established. The regularities of the formation of hydrophobic and antifriction properties in the composition of industrial oil I-20-surface-modified metal with various electrophilic-nucleophilic properties of the applied substances
Youth Participatory Action Research as a Catalyst for Health Promotion in a Rural South African School
Authors: Mathikithela Maite , Wood Lesley 
Published: June 2021

Rural schools in South Africa face many social and environmental challenges which impact negatively on learner wellbeing and performance. Given the severity and history of these problems, the situation is unlikely to change in the near future. Yet, schools are supposed to be enabling environments, providing holistic support to learners from communities plagued by severe economic, health and social challenges. A different strategy is clearly needed to promote the health and wellbeing of learners. Youth participatory action research (YPAR) appears to offer a plausible approach to kick start improved, health-promoting responses from within the school. We facilitated a YPAR process with volunteer learners from Grade10 to find out how they could begin to transform their rural school. Using arts-based methods, the learners were successful in raising awareness of the negative effects they were suffering as a result of the poor social-emotional climate in the school, the unsanitary facilities and the lack of opportunities to engage in physical exercise. The actions they took to address these issues were a catalyst for ongoing positive change in the school. The findings add to literature about how YPAR can make schools more enabling spaces.
Auditory Streaming Complexity and Renaissance Mass Cycles
Authors: Upham Finn , Cumming Julie 
Published: June 2021

How did Renaissance listeners experience the polyphonic mass ordinary cycle in the soundscape of the church? We hypothesize that the textural differences in complexity between mass movements allowed listeners to track the progress of the service, regardless of intelligibility of the text or sophisticated musical knowledge. Building on the principles of auditory scene analysis, this article introduces the Auditory Streaming Complexity Estimate, a measure to evaluate the blending or separation of each part in polyphony, resulting in a moment-by-moment tally of how many independent streams or sound objects might be heard. When applied to symbolic scores for a corpus of 216 polyphonic mass ordinary cycles composed between c. 1450 and 1600, we show that the Streaming Complexity Estimate captures information distinct from the number of parts in the score or the distribution of voices active through the piece. While composers did not all follow the same relative complexity strategy for mass ordinary movements, there is a robust hierarchy emergent from the corpus as a whole: a shallow V shape with the Credo as the least complex and the Agnus Dei as the most. The streaming complexity of masses also significantly increased over the years represented in this corpus.

The aim of this study was to investigate NO- and lipid peroxidation (LPO)-related airway reactivity and its correlation to ventilation disorders in different clinical variants of asthma. NO, malone dialdehyde, IL-4, TNF-α, and IgE were measured in BAL fluid and blood serum of 39 asthma patients and 15 healthy volunteers matched for age and gender.In patients with stable asthma, airflow parameters in small and medium airways were significantly decreased compared to those of healthy persons. Concentrations of key cytokines of atopic inflammation in BAL fluid and serum were increased in asthma patients. Serum IgE tended to decrease and IL-4 and TNF-α in BAL fluid increased in asthma patients while the disease worsened. Inverse correlations were found between NO and TNF-α, malone dialdehyde concentration and parameters of bronchial obstruction.In conclusion, NO production in airways is caused by strong accumulation of inflammatory cells with high metabolic activity resulting in release of inflammatory and pro-inflammatory cytokines which regulate immunopathological reagine-induced inflammation.
Strukturalność a dedukcyjność matematyki: współczesny strukturalizm w filozofii matematyki

Wspólne dla różnego typu strukturalizmów matematycznych jest stwierdzenie, że dla matematyki jako nauki prawdziwa jest koniunkcja: a) matematyka jest nauką o strukturach oraz b) matematyka jest nauką dedukcyjną.
Przedstawiane są odmienne argumenty na rzecz tych dwóch własności matematyki i różnie rozumiane są pojęcia strukturalności i dedukcyjności, co skutkuje powstawaniem różnego rodzaju strukturalizmów. Twierdzimy, że przy pewnym ustalonym sposobie rozumienia tych pojęć możliwa jest ich równoważność. Argumentujemy na rzecz takiego rozumienia strukturalizmu, które streszcza się w stwierdzeniu: a) matematyka jest nauką o strukturach wtedy i tylko wtedy, gdy b) matematyka jest nauką dedukcyjną.
O uporczywej terapii oraz środkach zwyczajnych i nadzwyczajnych w polskim kontekście bioetycznym. Na marginesie dwóch debat Polskiego Towarzystwa Bioetycznego
Authors: Ferdynus Marcin 
Published: June 2021

W artykule rozważam opinię mówiącą o rezygnacji z terminu „uporczywa terapia” i o potrzebie zastąpienia go terminem „terapia medycznie daremna”. Ponadto zastanawiam się nad przydatnością podziału środków medycznych na zwyczajne i nadzwyczajne. Opowiadam się przeciwko odrzuceniu terminu „uporczywa terapia”, jak również staram się pokazać, że klasyfikacja środków medycznych, która łączy pary pojęć „proporcjonalne/nieproporcjonalne” i „zwyczajne/nadzwyczajne”, może stanowić skuteczną pomoc w podejmowaniu decyzji o rezygnacji z uporczywej terapii zarówno dla lekarza, jak i dla pacjenta. Przedmiotem refleksji czynię wypracowaną przez Polską Grupę Roboczą ds. Etyki Końca Życia definicję uporczywej terapii oraz jej zmodyfikowaną wersję. Zasadniczym kontekstem prowadzonych analiz są opinie niektórych autorów biorących udział w debatach zorganizowanych przez Polskie Towarzystwo Bioetyczne na temat uporczywej terapii oraz terapii medycznie daremnej.

Relevance. In the Western Siberia conditions bulb onion is grown mainly from onion sets. With this method of cultivation, large costs are spent on growing and storing the onion sets. In this regard, the cultivation of it through the seeds is of particular importance. This problem has not been studied enough in Priobskaya zone of Altai Territory conditions.Materials and methods. In our research, we studied the influence of cultivation conditions on the formation of economically valuable traits of varieties and a hybrid of bulb onion grown by sowing seeds in the ground in Priobskaya zone of Altai Territory. Three varieties were taken as objects of research: Odnoletniy Sibirskiy, Zolotnichok, Odintsovets, and one Candy F1 hybrid.Results. On average, over the years of research on early maturity, the standard Odnoletniy Sibirskiy variety (87-88 days) showed itself to be the most early maturing. Candy F1 hybrid can be used as a source of early green mass. Leaf regrowth was the earliest of all onion samples studied. The largest leaf apparatus in the conditions of Priobskaya zone of Altai Territory is formed by the varieties Odintsovets (4.1 pieces per plant) and Odnoletniy Sibirskiy (3.8 pieces per plant). The maximum bulb mass was formed by the Candy F1 hybrid (51.5 g). The Candy F1 hybrid also was distinguished by the highest yield in the group of the studied samples. The increase in total yield was 5.1 t/ha, marketable 2.4 t/ha in relation to the standard. The maximum marketability in the experience was in the standard (80.9%).

Relevance. To produce garlic for use both in the domestic and foreign markets, there is no required number of high-yielding varieties with large onions and a small number of cloves, as well as resistant to new growing conditions. In selection with a culture of garlic, in addition to zoned varieties, it is advisable to use local improved forms, however, the morphobiological characteristics of garlic can change depending on the growing conditions and, as a result, plants can die, reduce resistance, productivity and quality indicators, which depend on the breeding and genetic characteristics of the variety.Methods. The research was carried out on the experimental field of the Department of Horticulture, UO BSAA. The 67 samples of winter garlic were studied. The collection material consisted of varieties and clones that were selected from six regions of Belarus. The Belovezhsky variety was used as a control.Results. According to the results of the studies, the best in terms of bulb weight, number of cloves in the bulb, clove weight and yield were selected samples – AM1–18, OR3–18, OP5–18, MM1–18, UG–18, ЮM1–18, 2000–18, MГ1–18, DM–18, MГ4–18, varieties Agaton, Antonik, Gorets, Soyuz, Junior.

Relevance. In Uzbekistan, especially in the south of the republic, in recent years, early ripe varieties of onion Sumbula, Ravnak, Bakhora have become widespread. However, the technology of seed production of early maturing varieties has not been developed. In this regard, several studies were carried out to identify the optimal time for planting the mother plants of the early maturing onion variety Sumbula by using the favorable climatic conditions of southern Uzbekistan.Material and methodology. The material for the research was the early ripe onion variety Sumbula, bred by the Research Institute of Vegetable and Melon Crops and Potatoes. The studies were carried out according to the Methodological guidelines for the ecological testing of vegetable crops in the open field etc. The dates of seed planting were studied.Results. Studies have shown that the highest seed yield (0.97 t/ha) was obtained in the early autumn planting of mother plants on September 1. It was 20% more than in the control variant – September 15. At later planting dates, the seed yield decreases sharply.When mother plants were planted on October 30, the seed yield was only 0,46 t/ha, or 59.7% of the control.The yield of onion seeds increases, mainly due to the more powerful development of plants during early autumn planting – the formation of large leaves, inflorescences, and additional arrows. The more large and powerful leaves, the more plants have the ability to synthesize plastic substances in the process of photosynthesis and accumulate a high yield.

Relevance and methods. Leek is one of the most promising onion crops for industrial cultivation in the Non-Chernozem zone, which has medicinal properties and high nutritional value. The results of studying the technological features of leek cultivation in the open ground of the Moscow region are presented. The studies were carried out in 2019-2020 on the territory of the “Vegetable Experimental Station named after V.I. Edelstein". We studied the influence of the feeding area of leek seedlings on the biometric parameters of plants and the quality of products. The object of the study is the variety Karantansky, experimental options: 1) seedling feeding area – 6 cm2 (control), 2) seedling feeding area – 8 cm2 , 3) seedling feeding area – 10 cm2 . The objects of research to study the content of ascorbic acid were leek varieties: late-ripening – Karantansky (standard), Bandit, Dobry Molodets, mid-ripening – Columbus, Hobot slona.Results. It is noted that the feeding area during the seedling period does not significantly affect the biometric parameters of leek plants: leaf area, plant weight, leek pseudostems diameter. Therefore, during the period of growing seedlings, from the point of view of rational use of the area in the seedling department, it is recommended to use the minimum feeding area – 6 cm2 . It was also found that the studied varieties accumulate ascorbic acid in different ways in various plant organs. The maximum content of ascorbic acid was noted in the leek pseudostems of the control late-ripening variety Karantanskiy – 23.6 mg%. The minimum values are for Dobry Molodets (11.8 mg%) and Hobot Slona (11.9 mg%).
A Policy Agenda for Legal Education and Training and the Fourth Industrial Revolution: The Case of England and Wales
Authors: Le Roux-Kemp Andra 
Published: June 2021

While the full impact of the Fourth Industrial Revolution remains uncertain, it is by now generally accepted that highly intelligent technologies and their applications – such as robotics, artificial intelligence (AI), machine learning, digitialisation, and big Data – will continue to fundamentally transform all aspects of our occupational and personal lives. Yet, in the realm of higher education policy and specifically with regard to non-STEM disciplines like law, thorough-going engagement with this most recent wave of technological development remains lacking. It is the aim of this article to set a policy agenda for legal education and training that is sensitive to the opportunities and potential negative outfall of the Fourth Industrial Revolution (now exacerbated by COVID-19), while also taking into consideration the distinctive nature of legal education and training in England and Wales. Set against the higher education policy landscape of England and Wales, a number of concrete recommendations are made for bringing legal education and training into the age of the Fourth Industrial Revolution. These include, for example, a call for the radical transformation of the traditional, linear, and monodisciplinary LLB degree, addressing current and projected skills gaps and skills shortages by way of, inter alia, curriculum reform, and working towards greater mobility of law graduates between different legal jurisdictions and also within one jurisdiction but amongst different roles. These changes are necessary as legal education and training in England and Wales currently leave law graduates ill-equipped for the future labour market and do not adequately value and build on the job-tasks that legal professionals uniquely supply.

Published: June 2021

Employment has an important role to support a certain economy. The number of female workers have increased every year, due to family welfare fulfillment and female role shifting as a head of households. This paper aims to observe the driving factors of female labor force participation in East Java-Indonesia. Logit model is incorporated to estimate the parameters which involved total sample of 23.218 women in productive age which consist of 13.473 working women and the rest of 9.745 non working women in East Java. On the basis of micro data level from National Labor Force Survey (Sakernas) 2018, the result shows that age, education level, marital status, head of the household status, household size, rural-urban location, and income have a substantial effect on FLFP in East Java.

The effects of low-input training systems on viticultural costs on flat terrain and steep slope sites
Authors: Strub Larissa , Stoll Manfred , Loose Simone Mueller 
Published: June 2021

Low-input training systems, such as minimal pruning (MP) and the semi-minimal pruned hedge (SMPH), require less working hours as a result of fewer viticultural process steps and permit a higher degree of mechanisation. However, their effect on viticultural costs and per litre costs on both flat terrain and steep slopes has not yet been analysed. This study quantifies the viticultural costs of vertical shoot positioning (VSP) and low-input training systems for standard processes on different types of flat terrain and steep slope vineyards. The costs were obtained from a dataset of 1,519 working time records of labour and machine hours from 20 vineyards belonging to five German wine estates over three years. The costs for standard viticultural processes were compared across three pairs of VSP and low-input training site types with different mechanisation intensities. The comparison was carried out by univariate analysis of variance with fixed and random effects, and by descriptive analysis of mean values.On flat terrain, SMPH significantly decreased the costs for the viticultural steps of winter pruning, tying, shoot positioning and defoliation, but it increased the cost for pest control. Hence, the total cost on flat terrain decreased marginally, but still significantly, by 46 %. The cost effects on steep slopes were similar, decreasing by 34 % for SMPH in unsupported steep slope harvester sites and by 46 % for MP rope and winch-supported steep slope sites. The per-litre costs were calculated for different yield levels. Since the yield in low input systems is higher than in VSP, the production costs per litre further decreased.The study confirmed the high cost-saving potential for wine growers of the mechanisation of canopy management and the omission of winter pruning in low-input systems. Combined with higher yields, the cost savings from low-input systems are particularly suitable for producers of bulk wine and market entry and mid-level wine profiles. By converting to low-input systems, the costs associated with mechanisable steep slope vineyards can be reduced to amounts approximating VSP on flat terrain. For certain wine profiles, low-input systems should therefore constitute an integral part of strategies to increase the economic sustainability of steep slope viticulture. The estimated cost benchmarks provide critical input for the cost-based pricing policy of steep slope growers. These benchmarks also give agricultural policy reliable indicators of the subsidies required for preserving steep slope landscapes.
