Schwarzer Feminismus der Grenze. Die Refugee-Frauenbewegung und das Schwarze Mittelmeer
Authors: Barry Céline
Published: December 2021

Im dominanten neoliberalen Kontext gerät die Frage der Dekolonisierung – im materiellen Sinn – oft in den Hintergrund antirassistischer Politiken. Wie radikale Schwarze feministische Zusammenhänge historisch sowie gegenwärtig einfordern, ist die Frage der Dekolonisierung in Kämpfen gegen Rassismus jedoch zentral. In diesem Sinne behandelt mein Artikel die Frage der antikolonialen Ausrichtung der Schwarzen Frauenbewegung in Deutschland: An welchen Stellen werden vergeschlechtlichte Manifestationen anti-Schwarzen Rassismus mit der Frage neokolonialer Grenzregime, die an der Basis heteropatriarchaler anti-Schwarzer Strukturen ist, in Verbindung gebracht? Es zeigt sich, dass das panafrikanische Erbe des transnationalen Schwarzen Feminismus antikoloniale Praxis fest in die Schwarze feministische Bewegungsgeschichte in Deutschland einschreibt. Insbesondere der Feminismus der Grenze, den Schwarze geflüchtete Frauen, Lesben, Non-Binarys, Queers, Inter und Trans aus afrikanischen Kontexten praktizieren spielen hier eine tragende Rolle. Ihre situierte Kritik Grenzregime erweist sich für eine antikoloniale Schwarze feministische Praxis als richtungsweisend und befördert die Entfaltung des widerständigen solidarischen Raums des Schwarzen Mittelmeers.
Die Orte, an denen wir heilen. Für Schwarze Communities of Practice, Dialogue and Care

Published: December 2021

Weltweit waren 2020 2,3 Millionen Frauen weltweit von Brustkrebs betroffen, 685.000 starben daran. Dies macht Brustkrebs zu einer der am weitesten verbreiteten Krebserkrankung. Laut US-Studien haben Schwarze Frauen – im Vergleich zu weißen Frauen – relativ höhere Inzidenzen von und Risiken für schwerere Verläufe und tödliche Formen von Brustkrebs. Dies ist alarmierend angesichts der Tatsache, dass die frühzeitige Erkennung und adäquate Behandlung von Brustkrebs enorm wichtig und lebensrettend sind. Die Gründe für die unterschiedlichen und erhöhten Inzidenzen und Risiken sind vielfältig. In Deutschland existieren spezifische Analysen der Auswirkungen von Rassismen und anderen Formen intersektionaler Diskriminierungen im medizinischen System einerseits und deren multiple Wirkweisen (Traumata, Erkrankungen, Ausgrenzung u.v.m.) andererseits nicht. Vor dem Hintergrund der Erfahrung mehrfacher Traumata, durch Diskriminierung, Ausgrenzung und möglichen Auswirkungen historischer Dimensionen auf den Körper, plädiert der Artikel einerseits dafür, Schwarze Communities und Individuen ernst zu nehmen und hier eine Gestaltung von Communities of Practice, Dialoge and Care für Schwarze Frauen und LGBTIQA+ zu gestalten. Anderseits zielt er auf grundlegende Transformationen des Medizinsystems, die die intersektionalen Realitäten Schwarzer Frauen und LGBTQIA+ reflektieren und integrieren und so eine diskriminierungs- und rassismusbewusste inklusive gendergerechte gleichberechtigte und chancengerechte Medizin für alle ermöglichen.

Authors: Dash Prosanta K. , Chase Carlene A. , Agehara Shinsuke , Zotarelli Lincoln
Published: December 2021

BACKGROUND:

Earlier planting under subtropical climatic conditions has been proposed as a means of increasing strawberry ( Fragaria× ananassa Duch.) profitability but exposes transplants to heat stress.

OBJECTIVE:

Therefore, physical and chemical methods of ameliorating heat stress on the establishment, growth, and yield of containerized strawberry transplants were evaluated.

METHODS:

We used a split-plot design with white-on-black (white) mulch and black mulch as main plot treatments; and a factorial arrangement of transplant type and stress-prevention application was randomly assigned to the subplots. ‘Florida Radiance’ Jiffy plug and tray plug transplants were treated either with s-abscisic acid or with kaolin.

RESULTS:

White mulch resulted in greater plant vigor and vegetative growth than black mulch. Kaolin plus white mulch provided protection against heat stress as indicated by increased photosynthesis rates. At 4 weeks after transplanting, plant vigor and shoot growth were higher and flowering occurred earlier with Jiffy plug transplants than with tray plug transplants. Early marketable yields were higher with white mulch than with black mulch in three of the four site years.

CONCLUSIONS:

A combination of white mulch, Jiffy plug transplants, and kaolin application appears to have the best potential for alleviating heat stress during early-season strawberry establishment under subtropical conditions.
BRCA1-Associated Protein 1 (BAP-1) as a Prognostic and Predictive Biomarker in Clear Cell Renal Cell Carcinoma: A Systematic Review
Authors: Gulati Shuchi , Previtera Melissa , Lara Primo N.
Published: December 2021

BACKGROUND:

The gene that encodes BRCA1-associated protein 1 (BAP1) has been reported to be dysregulated in several human cancers such as uveal melanoma, malignant pleural mesothelioma, hepatocellular carcinoma, thymic epithelial tumors, and clear-cell renal cell carcinoma (ccRCC). The gene is located on the human chromosome 3p21.3, encoding a deubiquitinase and acts as a classic two-hit tumor suppressor gene. BAP1 predominantly resides in the nucleus, where it interacts with several chromatin-associated factors, as well as regulates calcium signaling in the cytoplasm. As newer therapies continue to evolve for the management of RCC, it is important to understand the role of BAP1 mutation as a prognostic and predictive biomarker.

OBJECTIVE:

We aimed to systematically evaluate the role of BAP1 mutations in patients with RCC in terms of its impact on prognosis and its role as a predictive biomarker.

METHODS:

Following PRISMA guidelines, we performed a systematic literature search using PubMed and Embase through March 2021. Titles and abstracts were screened to identify articles for full-text and then a descriptive review was performed.

RESULTS:

A total of 490 articles were initially identified. Ultimately 71 articles that met our inclusion criteria published between 2012–2021 were included in the analysis. Data were extracted and organized to reflect the role of BAP1 alterations as a marker of prognosis as well as a marker of response to treatments, such as mTOR inhibitors, VEGF tyrosine kinase inhibitors, and immune checkpoint inhibitors.

CONCLUSIONS:

Alterations in BAP1 appear to be uniformly associated with poor prognosis in patients with RCC. Knowledge gaps remain with regard to the predictive relevance of BAP1 alterations, especially in the context of immunotherapy. Prospective studies are required to more precisely ascertain the predictive value of BAP1 alterations in RCC.

Published: December 2021

The article examines the properties of the colored surface of the Art object as a means of creating a harmonious architectural environment. The question was raised about the relevance of increasing the comfort, functionality, ergonomics, environmental friendliness and aesthetics of the design of the architectural environment, which is associated with global problems caused by the deterioration of the environment and unprecedented measures in connection with the pandemic. Taking into account the fact that the introduction of elements of fine art into the architectural space is always accompanied by only positive emotions, the necessary design of various types of Art objects in the modern architectural space has been determined. It is indicated that the artistic material is the main factor in the objects of fine art, capable of participating in the formation of the aesthetic perception of the environment. The analysis of the existing sources of theoretical and practical experience has shown the relevance of this problem.

Based on the results of the analysis, the main properties of the colored surface were systematized, identified and determined, which affect the perception of the texture of colored surfaces of different types of art forms of Art objects, depending on the following factors: 1) color saturation and lighting; 2) distance from observer; 3) property of the surface of the material and the nature of its processing; 4) the color tone of the material surface, its saturation and lightness. Methods of its use in different types of Art objects are proposed. Typical examples of the practical implementation of the use of Art objects using the possibilities of a colored surface in a modern architectural space, made by the authors of the study and modern examples of world art, are presented in a visual table.

Based on the results of the study, the main tools were identified that may be necessary in the design practice of architects, designers, artists to create a harmonious architectural environment.
SPATIAL PLANNING OF TERRITORIES AS A NEW TYPE OF URBAN PLANNING ACTIVITY. PROBLEMS AND PROSPECTS
Authors: Stepanyuk Andriy , Kiuntsli Romana
Published: December 2021

Administrative and territorial reform in Ukraine is coming to an end. In the socio-economic life of the country, this reform contributed to the establishment of local self-government, in urban planning activities began spatial planning, the main task of which is the development of comprehensive plans for spatial development of the territories of united territorial communities.

According to the current legislation, the main subject of local self-government in Ukraine is a united territorial community. Adoption of the Law 711-IX "On Amendments to Certain Legislative Acts of Ukraine on Land Use Planning" provides for the development of special urban planning documentation, which extends its effect to the community, which in turn allows the united territorial community to determine the planning and development of its own territory. Law 711-IX also introduces a new type of urban planning documentation - a comprehensive plan for the spatial development of the territory of the united territorial community. In order to successfully implement this project, it is necessary to assess all the challenges and risks in the field of administrative services, medicine, education, road and engineering infrastructure, environmental protection and cultural heritage when drawing up a community spatial development plan in modern conditions.

The main problem in drawing up comprehensive plans is the spatial organization of agricultural areas and the interests of the peasant farmer, a representative of the middle class, whose opinion should be taken into account through surveys and analysis of his social and industrial activities, including taking into account his domestic and economic interests.

When drawing up comprehensive spatial development plans, the project team should involve community specialists (architect, land surveyor), as well as community proxies (priests, teachers) who know regional issues, history and traditional crafts of the territories and will defend their development. As many community residents as possible should participate in the discussion and approval of project proposals for a comprehensive plan, in order to prevent resistance and understand the need to implement it.
Recent Developments of Recombinant Protein Expression for Therapeutic Purposes
Authors: Amir Anam
Published: December 2021

In the most recent seven to eight years, the therapeutic recombinant proteins have rapidly expanded in the biotechnology domain due to its wide variety of needs. There has been significant development in the mammalian expression system for fine purification and increased level of expressed recombinant proteins [1,2]. Many drugs like tetracycline have been demonstrated on the Chinese Hamster Ovary cell line for promising multi control strategies and effective cytotoxicity. Mammalian expression system improves the proper glycosylation of recombinant proteins which are very helpful to increase solubility of product [3-6].

            Meanwhile on the prokaryotic expression system, E. coli has proven to be an easier to handle, friendly and economical strain [2]. Recently these expression systems are using to work on antibody fragment productions and their proper folding with co-expression of chaperones [7]. Moreover E. coli has been used for the production of cancer cell penetrating peptides which promises the targeted delivery of drugs to specific effector cells only.  Yeast systems are also being used for the antibody fragments production and the high level production of insulin. Interestingly cell free expression systems are also participating in this game and that would be very fascinating to see in the coming years about cell extract medium for production of high level recombinant protein [8, 9]. Purification and optimization of recombinant protein has always been a challenging situation for scientists and they paid more attention to increase the overall yield of the product. Many affinity chromatography techniques has been introduced for efficient purification of protein of interest [10].

Despite these research and developments in methodologies to produce and purify the recombinant therapeutic protein, scientists still face the hurdles and challenges with all expression systems. Rationally E. coli produces inclusion bodies and many mammalian cell types do not show the same results with the same recombinant protein. [11]. So there is a requirement for adding the appropriate features to the expression systems focused to better improvising recovery, production and purification of recombinant protein.

GASTRONOMICAL CODE AS ELEMENT OF EVERYDAY LIFE POETICS IN DRAMA TEXTS (ANTON CHEKHOV’S THREE SISTERS AND BETH HENLEY’S CRIMES OF THE HEART)
Authors: Vysotska Natalia
Published: December 2021

The paper sets out to explore the functions of food discourse in the plays Three Sisters by Anton Chekhovand Crimes of the Heart by Beth Henley. Based on the critically established continuity between the two plays, the paperlooks at the ways the dramatists capitalize on food imagery to achieve their artistic goals. It seemed logical to discuss thealimentary practices within the framework of everyday life studies, moved to the forefront of literary scholarship by theanthropological turn in the humanities. Enhanced by semiotic approach, this perspective enables one to understand foodproducts and consumption manners as performing a variety of functions in each play. Most obviously, they are instrumentalin creating the illusion of «everydayness» vital for new drama. Then, for Chekhov, food comes to epitomize thespiritless materiality of contemporary life, while in Henley’s play it is predominantly used, in accordance with the play’sfeminist agenda, as a grotesque substitute for the lack of human affection. Relying upon the fundamental cultural distinctionbetween everyday and non-everyday makes it possible to compare representations of festive occasions in the twoplays seen through the gastronomical lens of «eating together». Despite substantial differences, the emphases on alimentarypractices in the plays serve to realize the inexhaustible dramatic potential inherent in the minutiae of quotidian life.
DANCE AS A MARKER OF NATURAL CYCLES CHANGE IN TERRY PRATCHETT’S FANTASY NOVELS
Authors: Kanchura Yevheniia
Published: December 2021

Against the background of a widespread tendency to diminish the sacred meaning of ritual actions, Terry Pratchett’s strive to shed light on the archetypal principles of mythological consciousness in contemporary folklore makes it possible to restorethe connection of the old rites, which have lost their original sense, with the worldview bases of modern society and to reacralize the profane. The Elements of mythological consciousness, manifested in ritual actions inherent in the modern functioning of English folklore, play a meaningful and compositional role in Terry Pratchett’s novels «The Reaper» (1991), «Lords and Ladies» (1992) and «Wintersmith» (2006). In Pratchett’s novels, Morris dance, which traditionally heralds the summer beginning, is balanced by a dance that marks the beginning of winter, indicating the natural cycles change. This manifests the functions of a sacred act: a dialogue between the world and a human, extracting the last from the flow of everyday life, and finalizing the routine work of a farmer. The study suggests the analysis of artistic means describing the Morris dance ritual as a marker of natural cycle changes and as evidence of a human establishing contact with natural forces, enshrined in the narrative and embodied in the dynamic form of dance. A common harvest festival turns into a Dance of the Death and a Maiden, which moves the process of harvesting and preserving the harvest into the realm of the sacred. The motive of the Death and a Maiden dance is being developed in the same compositional plane with the Morris dance motive, as an element of the narrative about the natural balance of life and death,fertility and harvest, about the cycle of the universe based on the love drive. The article examines the compositional elements of choreographic ekphrasis, highlights the significant elements of such a description, indicates the markers of the sacred and the profane, intrinsic to ritual dance in Pratchett’s novels. The conducted research allows to determine the role of dance in Pratchett’s literature work as a marker of the transition from one state to another, as well as season cycle changes.

Published: December 2021

Introduction: Non-melanoma skin cancer (NMSC) is the most common among all malignancies. Objective: To describe trends in NMSC mortality rates in Brazil and its macroregions from 2001 to 2018. Method: Adjusted mortality rates stratified by sex were estimated and presented per 100,000 person-years. An autoregressive analysis was implemented to assess temporal trends, annual percent change (APC) and 95% Confidence Intervals (95% CI). Results: There were 27,550 NMSC deaths in Brazil with higher frequency in males (58.1%) and among individuals aged ≥70 years (64.3%). The overall rates were 2.25 (males) and 1.22 (females) per 100,000 person-years. The trends followed an upward direction in Brazil for males (APC: 2.91%; 95% CI: 1.96%; 3.86%) and females (APC: 3.51%; 95% CI: 2.68%; 4.34%). The same occurred in the North Region, in males (APC: 9.75%; 95% CI: 7.68%; 11.86%) and in females (APC: 10.38; 95% CI: 5.77%; 15.21%), as well as in Northeast Region, in males (APC: 9.98%; 95% CI: 5.59%; 14.57%) and in females (APC: 8.34%; 95% CI: 3.29%; 13.64%). Conclusion: NMSC deaths are not rare in Brazil. Upward mortality trends were observed for the whole country and in the North and Northeast regions, which are the closest to the Equator line and also the least developed socioeconomically. A synergism between different types of inequalities and environmental exposure in these macroregions may be promoting an increase in the number of NMSC deaths, a type of cancer which is considered completely preventable.

Peripheral Arterial Disease (PAD) is the narrowing of peripheral blood vessels which prevalence is high in the elders. In 2010, it was estimated that 202 million people were suffering from PAD, most of which are in developing countries, especially the Southeast Asia region. Inflammation markers such as leukocyte and C-Reactive Protein (CRP) can predict the incidence of PAD but their use in determining prognosis remains unclear. Complications in PAD include amputation, increased cardiovascular events, and even death. Aim: This study aims to determine the relationship between leukocyte and CRP level on complications in PAD, in the forms of amputation, cardiovascular events, and mortality. Methods: This is a meta analysis study which uses online literature sourced from Pubmed, Science Direct, Cochrane, and Google Scholar. Results: Based on the data analysis, there is a significant relationship between CRP with the incidence of amputation (HR 1.24, 95%CI: 1.02-1.49, p=0.03) and hs-CRP with cardiovascular events (HR 1.33, 95%CI: 1.10-1.60, p=0.003). Leukocyte on the other hand shows no significant relationship with the incidence of amputation (OR 1.10, 95%CI: 0.98-1.23, p=0.10) and mortality (OR 1.14, 95%CI: 0.97-1.35, p=0.12)

The development of technologically efficient and economical methods of using liquid pyrolysis products is a task of current interest. Despite the apparent variety of developments, the proposed methods are reduced either to obtaining a set of fractions, which are subsequently used as technical products, or to obtaining a wide range of individual compounds. The complexity and wastelessness of oil refining and petrochemistry, which has become especially acute due to the increasing negative impact of human activities on the environment, provides for the complete utilization of all material flows with the maximum extraction of useful components, the use of technologies, catalysts and reagents that exclude the formation of harmful emissions and waste. Currently, one of the most common methods for producing lower olefins (ethylene, propylene, butylenes) is the pyrolysis of hydrocarbons of various origins (gas, straight-run gasoline, a broad fraction of light hydrocarbons, etc.).

Fractions 85-180 °C, 180-360 °C of thermolysis oil are characterized by a high content of organosulfur compounds, which necessitates their hydrotreating before use. After desulfurization, gasoline and diesel fractions can be used in the composition of gasoline and diesel fuels, respectively. The diesel fraction of 180-360 °C of thermolysis oil has a high cetane number and can be considered as a cetane-increasing component. Fraction 360-КК оС thermolysis oil is a potential component of catalytic cracking feedstock. The highest degree of conversion and the yield of valuable components (gasoline, propylene, butane-butene fraction) are achieved during cracking of feedstock containing 30 wt. % of the heavy part of thermolysis oil.

Harezmi Educational Model, a national model first piloted in 2016, is based on the inclusion of multi-disciplines, use of computational skills in the problem-solving process, development of life skills, and using robotics, coding, and game designs in learning. Teachers interested in implementing this model are expected to attend in-service training for several weeks to gain theoretical knowledge and practical skills. The purpose of the present study is to explore how the whole process, from the training to implementation in class stages, has affected teachers’ beliefs, perceptions, and attitudes regarding teaching. Sixteen teachers participated in this study. Data came from an online survey with 11 open-ended questions and online focus group interviews. In the analysis, the recurring themes were determined through content analysis, and themes that emerged at the beginning and end were compared. The results suggested that besides developing a critical eye on their own teaching, teachers improved their collaboration skills and observed an increase in their autonomy. This study is an attempt to address a gap in the field concerning this model and how this model has the potential to contribute to the professional development of teachers.

Authors:   Santiago de Compostela University, Spain, Abbas Suraa A.
Published: December 2021

This paper sheds light on e-learning, whose importance has swiftly grown over the past year by learners after the closure of schools and universities in more than 100 countries worldwide due to the rampant Coronavirus disease (COVID-19), and the problems and solutions that must be followed to facilitate the educational process. This study is mainly quantitative. It will use quantitative research methods to collect data by distributing questions to the research community consisting of 10 teachers and 30 undergraduate students in the medical, technical faculty at Al-Kitab University. The data were analyzed by content analysis technique and divided into themes, sub-themes, and codes. The paper found that both students and teachers used technology to ensure the continuity of the educational process. In addition, both teachers and learners have different positive and negative opinions about the distance education platforms and the conditions facing them from the weakness of the Internet and the liability of electronic skills for both parties. Ideas were put forward on developing equipment and methods used for distance education activities using artificial intelligence to simulate the natural educational environment. This study recommends educational institutions restructure the curriculum and make it compatible with the electronic environment, just like the real academic environment.

Authors: Hachour K. , Talmat–Chaouchi N. , Moula R.
Published: December 2021

In 2018 and 2019 thirteen species of raptors, with 407 individuals, were found nesting in Great Kabylia in Algeria. During this period, 196 raptor nest sites were located (Falco tinnunculus is not included as it thrives in many biotopes and tolerates anthropization). We noted a decrease in specific richness and abundance of raptors in the region compared to data for 1992. Some raptors were not seen during our study: Gypaetus barbatus, Pandion haliaetus, Falco biarmicus, Circaetus aeruginosus, and Falco eleonorae. We classified nesting diurnal raptors into 3 classes according to their relative abundance: (1) widespread species (10-26 %): F. tinnunculus, Hieraaetus pennatus, and Buteo rufinus cirtensis; (2) common species (5-10 %): Elanus caeruleus, Falco peregrinus, Circaetus gallicus, Falco naumanni, Gyps fulvus, and Milvus migrans; and (3) uncommon species (1-5 %): Neophron percnopterus, Accipiter nisus, Aquila fasciata, and Aquila chrysaeto. With the exception of N. percnopterus, which is classified as an endangered species, the raptors of Great Kabylia are mainly classified in the category of species of least concern (IUCN, 2020).

Мета. Визначення щільності деревини та кори гілок крони дерев сосни звичайної в умовах Північного Степу із перспективою подальшого розроблення нормативного забезпечення визначення фітомаси крони сосняків досліджуваного регіону. Методи. Задля визначення природної і базисної щільності деревини та кори гілок закладено тимчасові пробні площі у кількості 25 штук, де для встановлення зазначених параметрів зрубано 25 модельних дерев. Дослідні зрізи деревини та кори проведено на трьох модельних гілках із різних частин крони. Вимірювання зрізів модельних гілок здійснено у 4-х точках периметру за двома взаємно перпендикулярними напрямками. Якісні показники щільності деревини та кори гілок ми визначали із використанням методики проф. П. І. Лакиди та із залученням пакету прикладного програмного забезпечення ZRIZ і PLOT. Результати. За результатами дослідження встановлено, що розраховані середні значення природної і базисної щільності деревини гілок є вищими за показники щільності кори. Порівняння показника середньої щільності гілок із тим самим показником в інших природних зонах України (Полісся та Лісостепу) виявило більш істотну розбіжність за показником природної щільності порівняно із базисною. Наведено основні статистики таксаційних показників дерев та показники базисної щільності компонентів гілок сосни. Крім того, представлено результати кореляційного аналізу тісноти зв’язків якісних компонентів фітомаси крони з основними таксаційними показниками дерев, тобто віком, діаметром та висотою дерева. Визначено, що показники щільності компонентів крони мають слабкий обернений кореляційний зв’язок із усіма таксаційними характеристиками дерев. Установлено, що на відміну від природної базисна щільність кори залежить насамперед від віку дерева. Висновки. За результатами дослідження якісних показників компонентів крони дерев сосни звичайної, середня природна щільність деревини гілок становить 850 кг·(м3)-1, кори гілок – 727 кг·(м3)-1; середня базисна щільність деревини та кори гілок дорівнюють відповідно 436 кг·(м3)-1 й 338 кг·(м3)-1. Зі збільшенням віку, діаметра та висоти дерев спостерігається зниження значень як природної, так і базисної щільності компонентів фітомаси крони. Частка кори гілок сосни звичайної зменшується із віком.

Мета. Метою роботи було вивчення асортиментуі стану використання мікробіологічних препаратів у землеробстві, вивчення властивостей препарату «ЕМ-А»і Сяйво 2.Методи. Експериментальну частину дослідженняпроводили протягом 2019–2020 рр. в умовах Уманськогонаціонального університету садівництва. Особливостіпроходження періодів онтогенезу та фенологічних фазрослин вивчали за методиками І. М. Бейдеман. Польовіта лабораторні дослідження проводили за загальноприйнятими методичними рекомендаціями.Результати. Вивчення динаміки наростання площілистків рослин васильків справжніх до початку першогоцвітіння (першого збирання) показало, що застосування мікробіологічних препаратів шляхом обприскування самої рослини значно вплинуло на цей показник.Зокрема, найбільшу площу листків сформували рослини варіанту обробки розчином ЕМ-А, яка становила61,6 тис. м2/га (у фазу бутонізації) та 65,5 тис. м2/га (передзрізуванням зеленої маси), що є більшим за показникиконтрольного варіанту на 16,3 та 14,1 тис. м2/га відповідно. Найменшу площу листків мали рослини контрольного варіанту досліду (45,3 тис. м2/га) у фазубутонізації. Надалі приріст площі листків рослин цьоговаріанту був також меншим на 6,1 тис. м2/га порівняноіз показниками періоду першого скошування зеленоїмаси. Рослини варіанту досліду із обприскуваннямрозчином Сяйво-2 були більш облистяними, площаповерхні листків на момент першого цвітіння в них була56,6 тис. м2/га, різниця із показником контрольного варіанту становить 5,2 тис. м2/га. Висновки. ЕМ-А сприяє інтенсивному росту і розвитку рослин завдяки збільшенню їхньої надземної біомаси, стимулює ріст кореневої системи і загалом урожайність рослин. Ефективні мікроорганізми покращуютьфізичний, хімічний і біологічний склад ґрунту. ТомуЕМ-технологія із використанням ефективних мікроорганізмів є перспективним напрямом підвищення кількостіта якості врожаю, поліпшення родючості ґрунту.

Published: December 2021

In this study, we utilized a random forest model to predict the “L” train’s daily ridership in the Chicago downtown area during the pandemic based on environmental, transportation, and COVID-19-related factors. The results indicated that the model accurately predicts ridership one month in advance. However, its accuracy degraded over time. Moreover, average temperature, stay-at-home order status, and percentage of home renters were found to be the most important factors contributing to ridership.

Allergy to bovine serum albumin is the main predictor of beef allergy associated with cow’s milk proteins allergy. We report a case of a 3-year-old child with cow’s milk proteins allergy since the age of 6 months who, after some ingestions of beef, developed episodes of irritability, urticaria and syncope. Specific IgE to beef, oral food challenge with medium rare cooked beef and specific IgE to bovine serum albumin were all positive, but an oral food challenge with well cooked beef was tolerated. Allergy to bovine serum albumin is not usually associated with severe reactions, since it is a thermolabile protein, however, the process of cooking meat may be insufficient to have an effect on the complex matrix of meat and associated serum albumins. The irregular pattern of the episodes and the previous diagnosis of cow’s milk proteins allergy may act as confounding factors leading to a delayed diagnosis.
