Published: April 2022

Teff is the most dominant staple cereals in Ethiopia, but yield levels are extremely low (1.2 t/ha) because of declining soil fertility, resulting in widespread national food insecurity. The aim of this study was to explore the effect of potassium (K) fertilization on teff yield and nutrient uptake in Vertisols in the central highlands of Ethiopia. Five levels of K (0, 30, 60, 90, and 120 K2O kg/ha) were applied as muirate of potash (KCl) arranged in RCBD with three farm fields as replicates. At crop maturity, a plot of 3 m × 3 m was harvested to measure teff yield and yield components and subsampled for laboratory analysis to determine nutrient uptake. Results showed a highly significant (p< 0.01) response of teff to K fertilizer application and significant differences among locations. When averaged across locations, the highest mean grain (1,875 kg/ha) and straw yields (6,774 kg/ha) were obtained with the application of 90 and 120 kg K2O/ha, respectively. However, the lowest grain (1,576 kg/ha) and straw (5,798 kg/ha) yields were harvested from control plots. This is about a 20% increase over the control. When averaged for all treatments, the highest mean grain (2,641 kg/ha) and straw (7,794 kg/ha) yields were obtained at Moretina Jiru and the lowest grain (1,280 kg/ha) and straw (4,210 kg/ha) yields were obtained at Sululta. Contrary to the popular view that Ethiopian Vertisols are rich in K, there are sites in the central highlands where K deficiency is limiting teff production. In sites where K-soil level was low and rainfall distribution was adequate, the application of K fertilizer along with the government recommended zinc blend fertilizer – NPSZn: 17.7 N + 35.3 P2O5+ 6.5 S + 2.5 Zn – significantly improves nutrient uptake, agronomic efficiency, and teff yields.

Kielė, D and Solianik, R. Four-week application of kinesiotaping improves proprioception, strength, and balance in individuals with complete anterior cruciate ligament rupture. J Strength Cond Res XX(X): 000–000, 2022—Kinesiotaping (KT) is common in musculoskeletal rehabilitation, but whether it is efficacious for surgically untreated anterior cruciate ligament (ACL) ruptures is unknown. Therefore, we evaluated whether a strategy of physiotherapy plus KT would be superior to a strategy of physiotherapy alone on subsequent proprioception and motor function. Men aged 28.1 ± 6.7 years with complete ACL ruptures were randomized to either a control (physiotherapy) or an experimental group (physiotherapy + KT) for a 4-week period. Changes in balance were assessed on the injured leg using a force platform. Knee angle reproduction, maximal voluntary contraction (MVC), and rate of force development (RFD) were measured using dynamometry, and pain was recorded using a visual analog scale. Decreases in knee pain and improvements in angle reproduction were observed in both groups (p < 0.05), with a greater effect on angle reproduction in the experimental group (p < 0.05). Both groups demonstrated increased isometric knee flexor MVC and RFD values (p < 0.05), but an increase in RFD of the knee extensors was observed only in the experimental group (p < 0.05). Furthermore, the MVC of concentric knee flexors at 60°·s−1 increased only in the experimental group (p < 0.05), whereas concentric MVC at 180°·s−1—resulting in greater hamstring-to-quadriceps ratios—increased in both groups (p < 0.05). Balancing ability on the injured leg increased only in the experimental group (p < 0.05). Thus, KT plus physiotherapy was beneficial in the treatment of proprioception, strength, and static balance in these individuals with an ACL rupture.
Paralympians Are Stronger Than You Know: A Comparison of Para and Nondisabled Powerlifting Bench Press World Records

van den Hoek, D, Garrett, J, Howells, R, and Latella, C. Paralympians are stronger than you know: A comparison of para and nondisabled powerlifting bench press world records. J Strength Cond Res 37(2): 452–456, 2023—This investigation explored the absolute and relative strength of bench press world record holders for World Para Powerlifting (WPPO) and International Powerlifting Federation (IPF) athletes. Athlete data (mass [in kilograms], competitive weight class, and bench press mass [in kilograms]) for world record holding male and female athletes were extracted from public databases. Absolute and relative strength (kg·kgbw
−1) of athletes was compared using IPF competitive weight classes. On an individual basis, WPPO world record holders demonstrated greater absolute strength than their IPF counterparts in 5 of 8 weight classes for women and 6 of 8 weight classes for men when classified using standard IPF competitive weight classes. Overall, effect sizes for relative strength were greater in WPPO male (19.6%, g = 0.75) and female (9.24%, g = 0.38) athletes but did not reach statistical significance. The greatest relative strength observed was 3.88 kg·kgbw
−1 (under 49-kg WPPO) for male and 2.72 kg·kgbw
−1 (under 50-kg WPPO class) for female athletes. For IPF athletes, the greatest relative strength was reported in the under 66-kg class for male athletes (3.35 kg·kgbw
−1) and under 63-kg class for female athletes (2.29 kg·kgbw
−1). The physical impairments experienced by WPPO world record holders do not appear to compromise bench press strength compared with able-bodied athletes. Indeed, WPPO world record holders often possess greater relative and absolute strength than their IPF counterparts. Superior para powerlifting bench press records may be, at least in part, the result of training and biomechanical factors and seem to be the only anaerobic strength-based sport where para records exceed that of able-bodied athletes.

Published: April 2022

Drug use and HIV are key issues for public health interventions in the Philippines. We examined associations of problematic drug use among 320 Filipinx transgender women (trans-WSM) and cisgender men who have sex with men (cis-MSM). The prevalence of exhibited problematic drug use in this sample was 29.38%. Greater odds of problematic drug use were observed among Filipinx participants who recently engaged in sex work (adjusted OR [aOR] = 2.79, 95% CI [1.08, 7.18]), reported having HIV positive and unknown status vs. negative status (aOR = 3.61, 95% CI [1.39, 9.39], and aOR = 13.99, 95% CI [2.04, 29.69], respectively), exhibited low HIV knowledge (aOR = 4.15, 95% CI [1.82, 9.44]), and displayed hazardous drinking (aOR = 2.77, 95% CI [1.21, 6.33]). Given its correlates of HIV-related indicators, integration of HIV and harm reduction services as a public health intervention could potentially decrease problematic drug use.
Coupling of Mouse Olfactory Bulb Projection Neurons to Fluctuating Odor Pulses
Authors: Dasgupta Debanjan , Warner Tom P. A. , Erskine Andrew , Schaefer Andreas T.
Published: April 2022

Odors are transported by turbulent air currents, creating complex temporal fluctuations in odor concentration that provide a potentially informative stimulus dimension. We have shown that mice are able to discriminate odor stimuli based on their temporal structure, indicating that information contained in the temporal structure of odor plumes can be extracted by the mouse olfactory system. Here, usingin vivoextracellular and intracellular electrophysiological recordings, we show that mitral cells (MCs) and tufted cells (TCs) of the male C57BL/6 mouse olfactory bulb can encode the dominant temporal frequencies present in odor stimuli up to at least 20 Hz. A substantial population of cell-odor pairs showed significant coupling of their subthreshold membrane potential with the odor stimulus at both 2 Hz (29/70) and the suprasniff frequency 20 Hz (24/70). Furthermore, mitral/tufted cells (M/TCs) show differential coupling of their membrane potential to odor concentration fluctuations with tufted cells coupling more strongly for the 20 Hz stimulation. Frequency coupling was always observed to be invariant to odor identity, and M/TCs that coupled well to a mixture also coupled to at least one of the components of the mixture. Interestingly, pharmacological blocking of the inhibitory circuitry strongly modulated frequency coupling of cell-odor pairs at both 2 Hz (10/15) and 20 Hz (9/15). These results provide insight into how both cellular and circuit properties contribute to the encoding of temporal odor features in the mouse olfactory bulb.

SIGNIFICANCE STATEMENTOdors in the natural environment have a strong temporal structure that can be extracted and used by mice in their behavior. Here, usingin vivoextracellular and intracellular electrophysiological techniques, we show that the projection neurons in the olfactory bulb can encode and couple to the dominant frequency present in an odor stimulus. Furthermore, frequency coupling was observed to be differential between mitral and tufted cells and was odor invariant but strongly modulated by local inhibitory circuits. In summary, this study provides insight into how both cellular and circuit properties modulate encoding of odor temporal features in the mouse olfactory bulb.

Grčki i latinski frazemi s toponimskom i etnonimskom sastavnicom
Authors: Mijić Linda , Bartulović Anita
Published: April 2022

Mnogi frazemi motivirani nekim antičkim događajem ili ličnošću, koji mogu biti ili povijesni ili mitološki, postali su općeeuropski te je njihovo značenje kao i pozadinska slika posve jasno (npr. trojanski konj, gordijski čvor, Ahilova peta, Pirova pobjeda itd.). Međutim, zbog fragmentarne sačuvanosti antičkih književnih i leksikografskih izvora frazemima s toponimskom i etnonimskom sastavnicom ponekad je teško u potpunosti odrediti kontekst pozadinske slike motivirane nekim manje poznatim kulturnim i geografskim osobitostima, mitološkim prizorima ili povijesno-političkim događajima i odnosima. U radu se na temelju leksikografske građe kontrastivno analiziraju grčki, latinski i njima podudarni hrvatski frazemi s navedenim sastavnicama. Semantičkom i konceptualnom analizom objašnjavaju se sličnosti i razlike u motivaciji, pozadinskoj slici i značenju pojedinih frazema grupiranih u različite koncepte, tj. predodžbe o određenoj izvanjezičnoj stvarnosti. Kontrastivna je analiza pokazala da većina frazema u analiziranome korpusu ima potpunu desemantizaciju i antropocentričnu usmjerenost te da su motivacijski neprozirni nacionalni frazemi s etnonimskom i toponimskom sastavnicom uglavnom negativno konotirani.
Cakavizam u viškim govorima
Authors: Šimičić Lucija
Published: April 2022

Cakavizam je specifična realizacija palatalnih suglasnika geografski ograničena na lokalne varijetete duž istočne obale Jadrana. Unatoč prijeporima i različitim hipotezama vezanim uz porijeklo cakavizma, od onih koji ga tumače kao posljedicu egzogenog (mletačkog) (Małecki 2007 [1929]; Hraste 1962), endogenog (slavenskog, odnosno čakavskog) (Hamm 1957; 1960; Moguš 1977), odnosno kombiniranog podrijetla (Muljačić 1966), autori se mahom slažu da se radi o isključivo čakavskom obilježju. Kao izrazito istaknuto obilježje cakavica je već dugo izložena postepenom napuštanju i to ponajviše u ranije cakavskim obalnim govorima, a zatim i u izoliranijim otočnim govorima. Govor Komiže smatra se najjužnijim cakavskim govorom (Małecki 2007 [1929]), a danas su viški govori među rijetkima koji cakavizam još uvijek čuvaju. Na temelju sociolingvističkog istraživanja na otoku Visu, koje se većinom temelji na uzorcima govorenog jezika prikupljenim intervjuiranjem govornika različite dobi, u radu se analizira jezična varijabilnost i promjena u pojavi cakavizma kako u stvarnom vremenu u odnosu na podatke prikupljene Upitnikom za Hrvatski jezični atlas tako i u prividnom vremenu među govornicima različite dobi. Iako je još uvijek prisutan, cakavizam je u svom punom obliku potvrđen još jedino kod najstarijih govornika. Prikupljeni uzorci govora pokazuju, naime, da se većina cakavskih realizacija svodi na depalatalizirani izgovor /č/, dok se tzv. srednji glasovi /ś/ i /ź/ čuvaju tek iznimno. Cakavizam je među mlađima i govornicima srednje dobi također posvjedočen, no u reduciranom i petrificiranom obliku. Osim toga, cakavizam je u viškim govorima danas često leksikalizirano i ne više produktivno obilježje.

Published: April 2022

Kastavski govori već više od stotinu godina intenzivno privlače pažnju mnogobrojnih domaćih i inozemnih slavista. Premda su se jezikoslovci ponajviše bavili akcenatskim osobitostima toga tipa govora jer je riječ o najstarijemu naglasnom sustavu zabilježenu na čakavskome terenu, neki su dijalektolozi svoju pažnju usmjeravali i na književno stvaralaštvo pisano kastavskom čakavštinom, uspoređujući izričaj pojedinih autora s podatcima dobivenima terenskim istraživanjima. U ovome se radu donosi pregled i analiza fonoloških i morfoloških jezičnih značajki potvrđenih u dvjema pjesničkim zbirkama Đurđe Grujičić pisanima čakavskim idiomom, Jubav od furešta i Dih. Cilj je istraživanja dokazivanje pripadnosti jezika kojim se ta autorica u navedenimzbirkama služi kastavskomu tipu govora, pri čemu je primijenjena metodologija temeljena na dijalektološkoj teoriji razlikovnosti, a koja obuhvaća jezične značajke triju hijerarhijskih rangova (alijetete, alteritete te arealne i/ili lokalne značajke) potvrđene u ekavskim čakavskim sustavima. Iako kastavska čakavština nije materinski govor Đurđe Grujičić, rezultati istraživanja pokazuju da se ona u dvjema analiziranim dijalektalnim zbirkama dosljedno služi autentičnim, izvornim oblikom toga idioma.

Abstrak. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pengetahuan dan keterampilan guru bidang studi bahasa Indonesia di Kabuaten Blora dalam penulisan artikel ilmiah dalam rangka meningkatkan profesionalitas guru. Metode yang digunakan dalam kegiatan ini bervariasi antara lain penyuluhan yang meliputi ceramah, diskusi (tanya jawab) dan pelatihan. Peserta kegiatan berjumlah 80 orang guru. Dari kegiatan tersebut terlihat bahwa para guru bidang studi Bahasa Indonesia dan bidang studi lain di  Kabupaten Blora masih banyak yang belum paham penulisan artikel ilmiah hasil penelitian. Hal ini bisa dimaklumi karena para guru belum pernah mendapat arahan dan pelatihan cara mengubah hasil penelitian menjadi sebuah artikel hasil penelitian yang siap dikirim ke jurnal tertentu. Dengan kegiatan ini, tentu ada pengetahuan baru tentang penulisan artikel ilmiah yang diperoleh oleh para guru di Kabupaten Blora.

Abstract. This activity aims to improve the knowledge and skills of teachers in the field of Indonesian language studies in Blora Regency in writing scientific articles in order to improve teacher professionalism. The methods used in this activity vary, including counseling which includes lectures, discussions (questions and answers) and training. The participants of the activity were 80 teachers. From these activities, it can be seen that there are still many teachers in the field of Indonesian language studies and other fields of study in Blora Regency who do not understand writing scientific research articles. This is understandable because the teachers have never received direction and training on how to turn research results into research articles that are ready to be sent to certain journals. With this activity, of course there will be new knowledge about writing scientific articles obtained by the teachers in Blora Regency.

Witchcraft Past and Present at the Peabody Essex Museum in Salem
Authors: Berger Helen A.
Published: April 2022

“Reckoning and Reclaiming,” an exhibition at the Peabody Essex Museum, located in the center of Salem, Massachusetts, ran from September 2021 through March 2022, bringing together materials from the Salem witch trials of 1692 with Frances F. Denny’s photographs of contemporary Witches and a video of Alexander McQueen’s’ haute couture fashion show that he claimed was inspired by the trials. The mix of old and new witchcraft was visually jolting. Although the new materials provided some relief from the main part of the show that documents the horror of the state supported terror that was the trials, the mixing and matching of the two did neither full service. It further-more served as its own form of commercialization of witchcraft; something that in the past that the museum has avoided.

Published: April 2022

Obesity is considered a global public health problem. Cesarean section has been associated with high body mass index (BMI) and increased obesity throughout life. However, this association has been challenged by some studies. This study aims to assess the causal effect of cesarean section on the BMI of children aged 1-3 years. This is a cohort study of 2,181 children aged 1-3 years, born in 2010, obtained from the BRISA Birth Cohort, in São Luís, state of Maranhão, Brazil. Sociodemographic variables, maternal characteristics, type of childbirth, morbidity, anthropometric measurements, and BMI were assessed. Marginal structural models with a counterfactual approach were used to check the causal effect of the type of childbirth on obesity, weighted by the inverse probability of selection and exposure. Out of the 2,181 children assessed (52% female), 50.6% were born by cesarean section, 5.9% of the newborn infants were large for gestational age, and 10.7% of them had excess weight. No causal effect of cesarean section on BMI was observed (coefficient = -0.004; 95%CI: -0.136; 0.127; p = 0.948). Cesarean section did not have a causal effect on the BMI of children aged 1-3 years.
O subsistema é nosso: mobilizações indígenas e a coletivização do cuidado no Brasil
Authors: Magalhães Aline Moreira
Published: April 2022

Resumo O artigo visa esboçar um panorama histórico e político sobre a relação entre indígenas e Estado no Brasil à luz do processo da Reforma Sanitária ocorrida a partir da década de 1970. Recupera e problematiza, com base em pesquisa e literatura em torno do tema, as concepções políticas subjacentes à diretriz participação, conforme prevista pela Constituição de 1988 e pela Lei Arouca de 1999, que implementa o subsistema de saúde indígena (SASI-SUS), assim como, em contrapartida, as operacionalidades efetivas da participação. À diferença do SUS, o SASI-SUS priorizou o aspecto federativo da gestão e a incorporação sistemática do debate sobre práticas e estratégias de cuidado indígenas no âmbito do atendimento cotidiano do subsistema, ambos apropriados pelo movimento indígena. Argumenta-se que a incorporação desses princípios constitui um elemento importante das relações entre movimento indígena e Estado.
Performance evaluation of green mortars developed from a ternary eco-cement of industrial solid wastes
Authors: Vo Duy-Hai , Hwang Chao-Lung , Huynh Trong-Phuoc
Published: April 2022

The performance of green mortars (GMs) incorporating an eco-cement made from various proportions of rice husk ash (RHA), ground granulated blast-furnace slag (GGBFS) and circulating fluidised bed combustion fly ash (CFA) was evaluated. Different RHA contents (15 wt%, 30 wt% and 45 wt%) were used to replace GGBFS (by weight) and these mixtures were activated by 15 wt%, 20 wt% and 25 wt% CFA by the total weight of GGBFS and RHA. The engineering properties of the mortars were examined by compressive strength, splitting tensile strength, water absorption, porosity and dynamic Young's modulus tests. Sulfate resistance tests and scanning electron microscopy (SEM) were conducted to evaluate the durability and microstructure of the GMs. The test results demonstrated that the content of RHA and CFA strongly impacted the properties of the GMs. The mortars with 20 wt% CFA and <30 wt% RHA showed the best performance at later ages. CFA decreased the sulfate resistance of the GMs, while RHA increased sulfate resistance and significantly reduced thermal conductivity. SEM images of the samples showed amorphous gels and the ettringite crystal-like phase, leading to a dense microstructure of the mortars.
Centrifuge modelling of ultra-thin high strength steel fibre reinforced concrete pavements
Authors: Smit Martha S. , Kearsley Elsabe P.
Published: April 2022

Ultra-thin continuously reinforced concrete pavement (UTCRCP) is an innovative pavement type that consists of a 50 mm high strength steel fibre reinforced concrete (HS-SFRC) layer overlain on a pavement substructure. The thickness results in a flexural stiffness significantly smaller than for conventional concrete pavements. In this paper, the conceptual understanding of the response of UTCRCP to traffic loading was investigated using centrifuge modelling. Simplified pavement models were subjected to a bidirectional moving axle load. The results indicated that axle loading, and not single wheel loading, should be used to investigate the response of UTCRCP as there is significant interaction in substructure deformation caused by the wheels on the ends of an axle. Due to the flexural toughness of the highly reinforced concrete layer, a gap forms between the ultra-thin HS-SFRC overlay and its substructure. Brittle, cemented bases between the HS-SFRC overlay and subgrade should be used with caution, as the flexible nature of the layers above and below the stabilised layer may result in rapid degeneration of the brittle layer.

Implications of credit constraint on the formalization of artisanal and small-scale mining (ASM) in sub-Saharan Africa
Authors: Eniowo O.D. , Meyer L.D. , Kilambo S.R. , Gerber L.J.
Published: April 2022

Artisanal and small-scale mining (ASM) operations continue to grow across sub-Saharan Africa and serve as a source of livelihood to many rural communities. Owing to safety, health, environmental, and social concerns, the occupation has been regarded as a menace in several sub-Sahara African countries. Recent studies in the field of ASM prescribe formalization as a way to tame its excesses while enhancing its potential. This paper explores the concept of formalization as it relates to ASM and how it is being affected by the funding situation. The paper seeks to address the question as to whether formalization of artisanal mining operations can achieve the desired results in view of the lingering credit constraints in this mining subsector. It is recommended that, as a way of extending the scope of formalization, focus should be placed not only on access to credit in ASM but also towards optimizing the creditworthiness of ASM firms, with the goal of improving the viability of the operations.
Рециклинговая экономика в постковидный период
Authors: Романенко Мария Игоревна
Published: April 2022

Цель: обоснование необходимости внедрения бизнес-модели, направленной на комплексную переработку отходов в новый материал с заданными параметрами и эксплуатационными свойствами, пригодный для дальнейшего использования. Обсуждение: в настоящее время человечество потребляет больше природных ресурсов, чем когда-либо. При этом количество отходов различных производств растет, что способствует образованию свалок и негативно влияет на окружающую среду. Это отрицательно сказывается на экономической, социальной обстановке регионов и страны в целом. Возникает необходимость отделить экономический рост производств от деградации и уничтожения окружающей среды, повысить эффективность использования ресурсов и содействовать устойчивому уровню жизни. Возврат в производственный цикл различных отходов и некондиционных материалов может внести существенный вклад в развитие экономики за счет перехода к низкоуглеводной и зеленой, рециклинговой экономике. Для этого требуется совершенствование методов использования природных богатств и отходов производств, налаживания сотрудничества между различными секторами экономики, заинтересованными сторонами и ветвями власти. Результаты: обоснован результативный эффект повторного использования материалов после окончания их жизненного цикла, а также различных видов строительных отходов и низкосортного сырья в качестве новых материалов с заданными свойствами. Выделенные группы описывают материалы, на которые следует первостепенно обратить внимание в связи с высоким уровнем возможного их дефицита. Сформированы направления приоритетного развития строительной отрасли в постковидный период. Проведенный опрос руководителей предприятий позволил сформулировать возможные риски предлагаемой бизнес-модели, базирующейся на развитии рециклинговой экономики.

Цель: уточнение значения сельской экономики для развития данного региона, а также доказательство такого факта, что для общего исследования места сельского хозяйства в территориальном народнохозяйственном комплексе необходимо, помимо роли отрасли в создании ВРП, необходимо уделять внимание ее доле в совокупности основных фондов, в количестве наемных работников и в структуре бизнес-единиц по отраслевой принадлежности. Обсуждение: агропромышленный комплекс для Воронежской области выступает крупной социально-экономической подсистемой, включающей несколько отраслей большого масштаба и распространения их предприятий практически по всей территории страны, отличающейся существенной долей в ВРП, предоставляющей тысячи рабочих мест, обеспечивающей ряд других социальных вопросов. Авторами статьи уточнено значение сельской экономики для развития данного региона. Результаты: проведенная оценка роли и важности сельского хозяйства для экономики и социальной жизни Воронежской области еще раз доказывает необходимость формирования и неуклонной реализации продуманной и четко скоординированной региональной аграрной политики, в том числе и в форме оказания финансовой помощи сельским товаропроизводителям.
Patterns of Knowledge-Intensive Business Services Use Across Europe
Authors:   National Research University Higher School of Economics, Chichkanov Nikolay
Published: April 2022

This paper examines the structure and the relevance of knowledge-intensive business services (KIBS) consumption for different industries. The research is based upon the analysis of national input-output tables for European countries presented in the last release of the World Input-Output Database (WIOD). The dataset allows for the identification of both the largest and the most intensive sectoral users of KIBS among different manufacturing, market services, and all other industries. The results confirm that the KIBS subsectors are very heterogeneous; patterns of consumption substantially differ across the six different types of KIBS that the data distinguish. It is suggested that these differences may be explained by the existence of specific synergies between each type of KIBS and some of the consuming industries.

We studied tussock communities with Eriophorum vaginatum attributed to the class Oxycocco-Sphagnetea Br.-Bl. et Tx. ex Westhoff et al. 1946 and predefined class Carici arctisibiricae–Hylocomietea alaskani class. prov. (Matveyeva & Lavrinenko 2021) Two new associations – Ledo decumbentis–Eriophoretum vaginati Lapshina ass. nov. (with 3 variants) and Pleurozio schreberi–Eriophoretum vaginati Lavrinenko et Lavrinenko ass. nov. (with subassociations typicum, shagnetosum lenenses, and sphagnetosum russowii) have been described in the bog class. The first association is confined to the southern tundra subzone of the West Siberian sector of the Arctic, while the second one to the East European sector of the Arctic, where the subassociations alternate along a gradient from the north of the typical tundra subzone to the south of the southern tundra subzone. The new association Arctagrostio latifoliae–Eriophoretum vaginati Lavrinenko O. et Lapshina ass. nov. has been categorized as zonal tundra vegetation. We compared these associations with syntaxa of the communities with Eriophorum vaginatum that were previously described in bog and zonal positions in the Siberian Arctic and Alaska.

Based on the solutions of contact problems for fibrous materials and coatings of composite materials, the article considers the implementation of the method of calculating the pliability of gears of composite materials, determining the contact parameters of coatings of fibrous materials. To calculate the contact deformations of gears made of metals and composites, a program was developed in the Delphi environment, which makes it possible to calculate the coefficients of contact deformation of the gear tooth, as well as the calculation of contact deformations for a tooth with a fibrous coating. An integral equation is presented, which gives a solution of the contact problem of pressing a stamp into an orthotropic coating. To study the influence of the properties of the material and the thickness of the coating on the contact parameters, a computer program was compiled, which was used to calculate for different thicknesses.
Children’s Narratives as a Space for Manifestation and Way of Diagnostics of Creative Abilities of Senior Preschoolers
Authors: Shiyan O.A. , Baranova A.A.
Published: April 2022

This paper discusses the approbation of an assessment tool for the creative abilities of preschoolers — dialectical structures and symbolic images — on the basis of children's narratives. Fifty-seven preschoolers of 6—7 years old from two preschool groups in Moscow took part in the approbation of the “Three Stories” technique. The groups contrasted in the quality of education, The significance of differences between the classrooms was defined using ECERS-3 and CASRS (Creative Ability Support Rating Scale). We analyzed whether there is a connection between the success of creating narratives and the results of diagnosing dialectical thinking, symbolic realism of imagination and creativity. In the approbation of the “Three Stories” technique, significant correlations were revealed between successful use of dialectical structures in a story-making and the results of diagnostics of dialectical thinking. The latter was executed with two corresponding tools: "What can be simultaneously?" (p=0,01) and "Dialectical stories" (p=0,05). Both dialectical structures and symbolic images in children's narratives demonstrated significant differences in contrasting groups (p=0,05). This approbation substantiated the validity of the technique for the study of creative abilities on the ground of children's narratives. The study allows us to consider children's narratives in terms of their resource for understanding and diagnosing (and, in the future, developing) the creative abilities of preschoolers.
