IntroductionIndividuals living with acquired brain injury experience numerous psychological, physical, and social challenges. Since the COVID-19 pandemic, many have experienced additional isolation, mental health issues and have had limited access to social and physical activities otherwise available in the community.Materials and MethodsBrain Waves is a 12-week online performance arts programme developed during the COVID-19 pandemic, for people with acquired brain injury (ABI). The research component of Brain Waves is a qualitative study, using Interpretative Phenomenological Analysis (IPA) and ethnographic methods (Observations and Interviews). The study will recruit two distinct populations: individuals living with acquired brain injury (including people who have experienced traumatic brain injury and stroke who are participating in the programme) and stakeholders (facilitators, involved in the delivery of Brain Waves). This paper presents the protocol for a project which aims to gain an understanding of the implementation and experiences of creating and participating in an online community-based performance arts programme.
The Yield and Weed Infestation of Winter Oilseed Rape (Brassica napus L. ssp. oleifera Metzg) in Two Tillage Systems
Authors: Gawęda Dorota , Haliniarz Małgorzata 
Published: April 2022

Results from a four-year field experiment were used to evaluate the effect of conventional tillage (CT) and no-tillage (NT) systems on the yield, selected yield and crop structure elements, weed infestation, and contents of fat and glucosinolates in the seeds of winter oilseed rape (Brassica napus L. ssp. oleifera Metzg). The study proved the beneficial effect of the NT system on the winter rape seed yield only during the precipitation shortage in the growing season. In the years with a sufficient sum of precipitation, a higher seed yield was produced in the CT than in the NT system. Considering the average values from the four-year study period, the seed yield and straw yield, plant density after emergence and before harvest, number of branches and main shoot length, and finally the 1000 seed weight were significantly higher in the CT compared with the NT system. In contrast, the NT system proved more beneficial regarding seed weight per silique and fat content of the seeds. The statistical analysis of the study results showed no effect of the tillage systems on the glucosinolate content of the seeds. In turn, a significantly higher number and air-dry weight of weeds as well as an increased density of Viola arvensis weeds were demonstrated in the NT plot compared with the CT plot of winter oilseed rape. Sonchus asper and Sonchus arvensis were identified in the NT plot but not in the CT plot. A significantly higher density of Chenopodium album and Euphorbia helioscopia weeds was detected in the CT system compared with the NT system. The statistical analysis of study results regarding weed community diversity showed similar values to the Shannon-Weinner diversity index (H’) in both tillage systems and a significantly higher value of the Simpson dominance index (SI) in the NT system compared with the CT system.

The interest of consumers to acquire Tequila has caused an increase in its sales. As demand increases, the Tequila industry must obtain its raw material at a constant rate and agave farmers must be prepared to satisfy this supply chain. Because of this, modernization of the strategies used to ensure a planned, scheduled, timely, and predictable production will allow farmers to maintain the current demand for Tequila. This has been evidenced in official historical records from 1999 to 2020 where there is a fluctuation in the price of agave due to supply and demand. Given this scenario, this research shows the development of a multivariable predictive mathematical model that will permit the agave–Tequila production chain to work based on a smart implementation of planned actions to guarantee the agave supply to the Tequila industry. The proposed model has a goodness of fit (R = 0.8676; R¯2 = 0.8609; F(1,20) = 131.01 > F0.01 (1,20) = 8.10) and demonstrates the impact on agave prices is due to several factors: Tequila exports (α = 0.50) > agave plants harvested “jima” (α = 0.44) > dollar exchange (α = 0.43) > Tequila production (α = 0.06) > annual accumulated precipitation (α = 0.05). Nevertheless, the price forecast can be influenced by climate change or economic crises that affect the supply chain. In conclusion, a prediction of agave price stabilization for five years is shown where authorized producers can evaluate future scenarios so that the agave supply chain can be guaranteed for Tequila production, facilitating the decision making regarding its raw material.
Common Pathogenetic Mechanisms of Ischemic Stroke and COVID-19: the Role of Focal and Systemic Inflammation
Authors: Сидорович Э.К. 
Published: April 2022

В результате аналитического обзора многих клинических и экспериментальных исследований установлены общие патогенетические механизмы развития ишемического инсульта (инфаркта мозга) и COVID-19. Они включают системное и фокальное иммунное гипервоспаление, нейроваскулярную эндотелиальную дисфункцию, эндотелиит, нарушение регуляции ренин-ангиотензин-альдостероновой системы, окислительный стресс, чрезмерную агрегацию тромбоцитов, гиперкоагуляцию, которые могут значительно влиять на исходы инфаркта мозга при COVID-19. Выявлена двунаправленная взаимоотягощающая связь между COVID-19 и инфарктом мозга. Коронавирусная инфекция COVID-19 может выступать как триггер, фактор риска и этиопатогенеза, а также фактор, усугубляющий ишемическое поражение головного мозга, способствующий долговременной отсроченной воспалительной реакции с хронизацией ишемии, развитием когнитивного расстройства. Вероятность развития инфаркта мозга при COVID-19 следует учитывать всегда, особенно у пациентов с тяжелым течением заболевания, что требует динамического неврологического наблюдения за пациентами, проведения соответствующих диагностических процедур. Требуются разработка и применение стратегий, направленных на коррекцию иммунного гипервоспаления у пациентов с ИМ при COVID-19.
As a result of an analytical review of many clinical and experimental studies, common pathogenetic mechanisms for the development of ischemic stroke and COVID-19 have been established. They include systemic and focal immune hyperinflammation, neurovascular endothelial dysfunction, endothelitis, dysregulation of the central nervous system renin-angiotensin-aldosterone system, oxidative stress, excessive platelet aggregation, and hypercoagulability, which can significantly influence the outcome of ischemic stroke in COVID-19. A bidirectional mutually aggravating relationship between COVID-19 and ischemic stroke was revealed. COVID-19 can act as a trigger, risk factor and etiological factor, as well as a factor that aggravates the cerebral ischemic damage, contributing to a long-term delayed inflammatory response with chronic brain ischemia and cognitive impairment. The likelihood of having ischemic stroke in the patients with COVID-19 should always be considered, especially in cases with a severe course of the disease; this requires dynamic neurological monitoring and appropriate diagnostic procedures. The development and application of strategies aimed to correct immune hyperinflammation in the patients with ischemic stroke and COVID-19 is required.

Значительное неравенство в доходах, приводящее к концентрации богатства и бедности, становится характерной чертой российского общества. В статье проведён статистический анализ показателей, характеризующих уровень бедности и дифференциации населения в Ярославской области. Для исследования выбраны основные показатели, принятые на государственном уровне для расчёта индикаторов уровня жизни, – среднедушевые доходы населения, коэффициенты фондов и Джини. Проведено моделирование распределения населения Ярославской области по среднедушевым доходам, а также статистическая оценка на базе этого распределения основных характеристик уровня бедности и дифференциации населения по доходам. Статистический анализ показал, что в 2020 году наблюдается сокращение процента населения с доходами ниже прожиточного минимума, а также снижение коэффициентов дифференциации населения. Это свидетельствует о том, что наметилась тенденция роста уровня жизни населения в Ярославской области.
Significant income inequality leading to a concentration of wealth and poverty is becoming a characteristic feature of Russian society. The article contains a statistical analysis of indicators characterizing the level of poverty and population differentiation in the Yaroslavl region. For the research the main indicators adopted at the state level for calculating indicators of living standards were selected – average per capita incomes of the population, ratios of funds and Gini coefficient. A simulation of the population distribution of the Yaroslavl region by average per capita income was carried out, as well as a statistical assessment based on this distribution of the main characteristics of the poverty level and the differentiation of the population by income. Statistical analysis showed that in 2020 there was a decrease in the percentage of the population with incomes below the subsistence minimum, as well as a decrease in population differentiation rates. This indicates that there has been a tendency to increase the living standard of the population in the Yaroslavl region.
