Экспериментальные исследования аэродинамических моделей в аэрохолодильной трубе являются основой для получения данных о влиянии обледенения на аэродинамику летательного аппарата (ЛА). Полученные в результате эксперимента льдообразования на модели необходимы как для оценки несущей способности крыла в условиях обледенения, так и для проверки и верификации физико-математических моделей и программ, описывающих процессы обледенения в различных условиях.Другим важным фактором использования аэродинамических моделей в аэрохолодильной трубе является имитация работы противо-обледенительной системы (ПОС) и выработка рекомендаций по ее рациональной работе применительно к разрабатываемому летательному аппарату.В работе представлена разработанная универсальная аэродинамическая модель отсека крыла гражданского самолета, предназначенная для проведения исследований по изучению форм льдообразований, а также для отработки алгоритмов работы ПОС.

Experimental studies of aerodynamic models in an air-cooling tunnel are the basis for obtaining data on the effect of icing on the aerodynamics of an aircraft. Ice formation on the model obtained as a result of the experiment is necessary both for assessing the wing bearing capacity under icing conditions and for checking and verifying physical and mathematical models and programs describing icing processes under various conditions.Another important factor in the use of aerodynamic models in an air-cooling tube is the imitation of the operation of the ice protection system (IPS) and the development of recommendations for its rational operation in relation to the aircraft being developed.The paper presents the developed universal aerodynamic model of the wing compartment of the civil aircraft, intended for research on the study of forms of ice formation, as well as for working out the algorithms for the operation of the IPS.

Manganese (Mn) is ubiquitous in the environment due to both geological and human activities. It is essential for plants, as for most other living organisms, but can also be toxic when it is present in excess. Some plant species, referred to as Mn hyperaccumulators, can accumulate over 10000μg/g of Mn in their shoot tissues without showing any phytotoxicity. Approximately 24 Mn hyperaccumulators are currently known worldwide. However, ample data is available the Mn hyperaccumulator species and biological significance of Mn hyperaccumulation and tolerance mechanisms. To give new insights, this review highlights the current knowledge of Mn hyperaccumulation and tolerance mechanisms in hyperaccumulators, which include root uptake, xylem loading, transport, sequestration, and detoxification processes. Hyperaccumulators uptake Mn mainly accumulates as Mn2+ into the xylem, from which it is then transferred to the shoots. Foliar Mn2+ is mainly stored in vacuoles, the endoplasmic reticulum, and the Golgi. It is sequestered by organic ligands and some transporter proteins at a subcellular level in the root and shoot, which can allow the plants to exhibit great tolerance. From the in-depth examine the published literature; the main knowledge gap and future research are highlighted. In addition, Mn hyperaccumulator biomass disposal methods and applications also discussed.

Primary Chronic Basophilic Leukemia (CBL) is an extremely rare disease and thus knowledge of this disease remains limited. There are no universal diagnostic criteria nor has the underlying pathogenetic mechanism been elucidated. In this peculiar case, we present a 93-year-old woman with an acute symptomatology of fatigue compounded by a manifest leukocytosis with 43% basophils in peripheral blood. The bone marrow aspirate also showed basophilia, 56% specifically. Interestingly, Next Generation Sequencing (NGS) on the bone marrow sample revealed three possible driver mutations, namely in the IDH2, DNMT3A, and BCOR gene. To date, NGS has never been performed on samples of patients with primary CBL. Our findings could be of great value in the search for the pathogenetic mechanism of this rare disease and to help find a successful treatment. Our patient was palliated with hydroxyurea to lower the white blood cells. Initially, this had a good effect, but unfortunately, she died two months after the diagnosis.

Published: February 2022

На показатели жирнокислотного состава яичного масла может влиять сбалансированность и полноценность питания самой курицы, поэтому количественное соотношение качественного состава этих показателей у разных пород домашней курицы и кур промышленного содержания явление не стабильное. Кроме того, на жирнокислотный состав яичного масла может оказывать влияние способ его получения (химическая экстрация, термическая дегидратация, условия хранения и т.д). Предложенный способ получения яичного масла - термическая дегидратация до обугливания - исключает использование экстрактивных веществ, таким образом, полученное масло не содержит искусственных компонентов.

The indicators of the fatty acid composition of egg oil can be influenced by the balance and nutritional value of the chicken itself; therefore, the quantitative ratio of the qualitative composition of these indicators in different breeds of domestic and industrial chicken is not stable phenomenon. In addition, the fatty acid composition of egg oil can be influenced by the method of its production (chemical extraction, thermal dehydration, storage conditions, etc.). The proposed method for producing egg oil - thermal dehydration before charring - excludes the use of extractives; thus, the resulting oil does not contain artificial components.

Authors: Мейсурова Александра Федоровна , Борисова Екатерина Алексеевна , Тарасова Екатерина Михайловна
Published: February 2022

Проведена оценка содержания пигментов в образцах лишайника Parmelia sulcata Taylor, собранных в рекреационных зонах города Твери разного уровня антропогенной трансформации и загрязнения. Выявлены существенные различия в содержании хлорофиллов a и b, что свидетельствует о высокой пластичности фотосинтетической системы. Уровень содержания Хл a в рекреационных зонах выше, чем в фоновых условиях. Высокая вариабельность значений концентраций Хл b свидетельствует о приоритетном значении пигментной системы при адаптации к изменению характеристик местообитания. При оценке уровня воздействия городской среды на биологические объекты информативным может быть соотношение содержания хлорофиллов. В ненарушенных природных экосистемах содержание Хл a больше, чем Хл b, а в антропогенно трансформированных - концентрация Хл a меньше, чем Хл b.

The content of pigments in the samples of the lichen Parmelia sulcata Taylor, collected in the recreational zones of the city of Tver at different levels of anthropogenic transformation and pollution, was assessed. Significant differences in the content of chlorophylls a and b were revealed which indicates a high plasticity of the photosynthetic system. The chlorophyll a content in recreational areas is higher than in background. The high variability of the chlorophyll b concentration indicates the priority value of the pigment system in adaptation to changes in habitat characteristics. When assessing the level of impact of the urban environment on biological objects, the ratio of the content of chlorophylls can be informative. In undisturbed natural ecosystems, the content of chlorophyll a is higher than that of chlorophyll b, while in the anthropogenically transformed ecosystems the opposite situation is observed.
The Effect of Natural Therapies in Combination with Usual Care for Depression: A Narrative Review
Authors: Chohan Prabhjot , Gratton Adam
Published: February 2022

Introduction: Major depressive disorder (MDD) is the most common and debilitating form of depression with a 12-month prevalence of 4.7% and a lifetime prevalence of 11.2% in Canada. Various classes of antidepressants are commonly used treatments for MDD; however, high failure rates occur due to adverse events and discontinuation of use. Non-drug and alternative interventions are commonly sought by people when drug treatment fails. The purpose of this investigation was to analyze the evidence on the effect of natural therapies in combination with pharmaceutical standard of care for the management of MDD
Methods: The following inclusion criteria were defined before conducting the literature search: 1) population of adults with major depressive disorder, 2) intervention of lavender, folic acid or acupuncture, combined with standard treatment, 3) comparison group of a placebo, standard treatment or natural therapy used alone, 4) changes to Hamilton Depression Rating Scale (HAM-D) as the primary outcome. PubMed, APA PsycARTICLES and Google scholar were used for the research. The articles were limited to randomized clinical trials (RCTs), and systematic reviews with meta-analyses. The different therapies were used as key words in the literature search.
Results: The literature search for ‘lavender’ yielded 214 studies, of which 3 RCTs met the criteria. ‘Folic acid’ yielded 680 studies of which 2 RCTs and 1 systematic review with meta-analysis met the criteria. ‘Acupuncture’ yielded 2240 studies of which 2 RCTs and 2 systematic reviews with meta-analyses met the criteria. Only the RCTs not summarized in the systematic reviews and meta-analyses were summarized in this review.
Discussion: All ten studies using natural interventions showed a statistically significant decrease in the mean score change versus comparison groups, however, the magnitude of the effect varied between the studies. Sample sizes were small and there was significant heterogeneity between studies.
Conclusion: Evidence suggests that natural therapies can be used adjunctively to the pharmaceutical care of MDD, however, the overall research quality is low and substantial heterogeneity exists between studies. Further, additional research using more rigorous methodologies and standardized interventions is needed.

The aim of this pilot study is to determine the kinematic elements of the free throw shooting technique among wheelchair basketball players from various classes. Three wheelchair basketball players from the wheelchair basketball club “Nais” took part in the study. The players were classified from IWBF classification 1, 3 and 4.5. All of the participants were right-handed. Free throw shooting recording were made with a fixed camera with a 1920 x 1080р resolution, 30 frames per s, positioned at a height of 1.20 m on the right side of the players facing the basket, at a distance of 7.5 m and 25 cm behind the free throw line. The “Kinovea” video program was used to process the results and the kinematic data for the free throw shooting technique of wheelchair basketball players. The kinematic parameters indicate differences in the performance of the free throw shooting technique among wheelchair basketball players from class 1, 3 and 4.5. A difference in successful throws between the participants from class 1, 3 and 4.5: the angle of ball release 50°, 52° and 47°, velocity of ball release 7.58 m/s, 6.25 m/s and 7.27 m/s, and height of ball release 164.49 cm, 180.71 cm and 190.86 cm, while the temporal parameters and angles of the elbow had the same values. We can conclude that for the successful performance of the free throw shooting technique a basketball player needs to achieve greater height of ball release in the final position.

What Factors Influence Physicians' Billing Accuracy?
Authors: J Champagnie Samantha
Published: February 2022

Every year, medical billing errors cost the United States government billions in public funds wrongfully or erroneously paid out. While recent reports indicate modest decline in hospital billing errors, the rate of physician evaluation and management billing errors show no signs of improvement. Opinions vary on the causes of these billing errors and consequently on the appropriate countermeasures. Despite this national crisis, to date, no strategies have proven to improve physician billing accuracy. This research examines the existing literature to explore theories and constructs that explain causal factors of physician billing errors and to illuminate gaps in the research which if explored, may result in potential strategies for improving billing accuracy.
Rise of the Citizen Developer

Published: February 2022

A worldwide shortage of developers has made low- and no-code platforms important and necessary. This paper investigates the use of these platforms in organizations, along with the role of workforce automation tools. A survey was conducted to find out how prevalent low- and no-code platforms and workforce automation tools are within companies. These platforms are used by citizen developers, employees who are working outside of the Information Technology (IT) department and are not professional programmers. With low- and no-code platforms citizen developers can create the applications that are needed by their work units or even their entire organizations. These platforms are seen as key to the demands of digital transformation. The results of this study are that companies both large and small are making use of low- and no-code platforms, as well as workforce automation tools. In addition, the majority of organizations have employees outside of the IT department who are creating technology solutions. The broad implication of this research is that citizen developers using low- and no-code platforms to create technology solutions may be the solution to the current shortage of developers. By using low- and no-code platforms, the citizen developer can create the applications that the manager needs for their team. This increases the technology available to the organization while at the same time reducing the pressure on the IT department.
Production Data Analysis Techniques for the Evaluation of the Estimated Ultimate Recovery (EUR) in Oil and Gas Reservoirs
Authors: Elmabrouk Saber Kh. , Mahmud Walid Mohamed
Published: February 2022

The calculation of oil reserves (estimate ultimate recovery, EUR) is required for reservoir management. It is important to differentiate between oil reserves and oil resources. The latter is roughly defined as the sum of recoverable and unrecoverable volumes of oil in place; whereas, the oil reserves can be defined as those amounts of oil anticipated to be commercially recoverable from a given date under defined conditions. However, there is always uncertainty when making reserve estimates, and the main source of uncertainty is the lack of available geological data. Depending on the quantity and quality of the available data, different methods are used for the evaluation of the EUR. A number of essentially straight-line extrapolation techniques (production data analysis) have been proposed to estimate the EUR for oil and gas wells. Thus, a detailed analysis of past performance of oil and water production data is required in order to predict the future performance of the oil and gas wells. This work utilized seven straight-line extrapolation techniques to estimate and compare the values of EUR of three oil wells from the same reservoir. The comparison shows very similar estimated EUR. Doi: 10.28991/HIJ-2022-03-01-09 Full Text: PDF

Published: February 2022

An ethnopharmacological study is an initial step for the development of jamu, which has been simultaneously conducted throughout Indonesia. This study aimed to explore the utilization of medicinal plants in Baturraden, a region with relatively rich plant biodiversity in Java. Our research is a quantitative ethnobotanical study reporting the utilization of medicinal plants as a single plant botanical preparation in the studied area. The data were collected through semi-structured interviews with 36 informants on the local names, indications, parts used, method of preparation, and application of the plants. The species use-value (SUV), relative frequency citation (RFC), and the fidelity level (FL) of each species were calculated accordingly. The study recorded the utilization of 47 species of medicinal plants, which were employed to treat 32 ailments. Leaves, decoctions, and oral were recorded as the most commonly used plant part, herbal preparation, and application. There were 24 botanical preparations with the FL value of 100%, which were indicated for the treatment of fourteen diseases/symptoms. Curcuma longa, Zingiber officinale, Piper betle, Cymbopogon citratus, Andrographis paniculata, Syzygium polyanthum, Citrus aurantiaca, and Zingiber montanum were considered as the most important and valuable plants by the local community. Hence, those plants should be evaluated further for their pharmacological activity and developed into standardized botanical preparations.

Temulawak (Curcuma xanthorrhiza Roxb.) is a medicinal plant for the raw material of traditional medicine in Indonesia. Temulawak can be a source of antioxidants and natural sunscreen because of its curcumin content. This study was conducted to determine antioxidant and sunscreen activity on Curcuma rhizome extract and nanoparticles extract and making cream preparations. Extraction using the maceration methods with 96% ethanol solvent, concentrated with a rotary evaporator and the thick extract of Curcuma rhizome was made into nanoparticles by ionic gelation methods. Spray drying methods dried the nanosuspension of Curcuma rhizome extract. The nanoparticles formed were evaluated for particle size, zeta potential and particle morphology. The dry powder nanoparticles and extract of Curcuma rhizome were tested for antioxidant activity by DPPH (2,2-diphenyl-1-picrylhydrazyl) methods and sunscreen using a UV-Vis spectrophotometer at λ = 290-340 nm. The antioxidant activity showed the IC50 value of the Curcuma rhizome extract was 78.30 μg/mL and nanoextract was 116.51 μg/mL. The sunscreen testing result showed that the SPF (Sun Protective Factor) value of Curcuma rhizome extract at a concentration of 0,012% was 14.14 and nanoextracts at a concentration of 0.04% was 7.73. Curcuma rhizome extract has relatively strong antioxidant activity, while the nanoextract was moderate. The sunscreen activity of Curcuma rhizome extract and nanoextract has maximum protection and extra protection.

This study aimed to evaluate the effect of water stress on some properties of roasted Big Jim chile. A flooded furrow irrigation system for chile peppers was performed with 4 treatments with different frequency days of irrigation: every 7, 9, 11 and 13 days for W1, W2, W3 and W4, respectively in a completely randomized design. Capsaicinoids were increased by water stress (P<0.05) showing increases about 160%; however, roasting process reduced the capsaicinoids content (P<0.05). Contents of linoleic, palmitic and arachidonic acids were not affected (P>0.05). Water stress reduced hexanal and linalool in about 64 and 72%, respectively (P<0.05), whereas 2-isobuthyl-3-methoxypyrazine increased (P<0.05). Water stress increased pungency and capsaicinoids content in chile, whereas the roasting process reduced pungency and no recatogarization on pungency is made.
LEARNERS’ PROBLEMS IN TRANSCRIBING WORDS IN CONNECTED SPEECH
Authors: Silalahi Pininta Veronika
Published: February 2022

This study is intended to investigate the difficulties encountered by the students of English department in transcribing words in connected speech where assimilation occurs. The assimilation investigated is limited to alveolars /t, d, n) to the neighbouring sound palatal /j, k,g/. Pronouncing words in connected speech is one of the problems that show up in learning EFL. The way words are spoken in isolation and in connected speech may differ significantly. Dealt with the difference, there are two questions to answer in this study. Question one is how students transcribe words in connected speech where assimilation occurs; question two is to describe what sound is assimilated to what sound. To answer the question of the study, descriptive qualitative design is applied. Data were collected from 50 students by giving 7 sentences to transcribe where assimilation occurs in a part of the sentences. Students were asked to transcribe the whole sentences and describe what sound has been assimilated to what sound. The result shows that 18 students can transcribe correctly the phonetic transcription of the assimilated sounds and describe what sound is assimilated to what sound. There are 32 students who transcribe the sentences as isolated words and cannot show where assimilation occurs. Thus, there is no description of the assimilation by these students. It leads to say that knowledge of pronouncing words in connected speech is poor. This suggests improvement by giving more practices in pronouncing not only individual words but words in connected speech. Students also need listening exercises to crosscheck the transcription they make while listening.

Published: February 2022

Since 1975, researchers have conducted interventions to improve the word-problem performance of elementary school students facing mathematics difficulties. The current study reports a meta-analysis of 52 studies that examined the effect of these interventions. We estimated multivariate, random-effects models (REM) with robust variance estimation (RVE) with and without outliers. Results showed a large, positive, and significant mean weighted effect size ( g = 1.01 for the model with outliers; g = 0.81 for the model without outliers). Findings of meta-regression analyses showed several moderators, such as sample composition, group size, intervention dosage, group assignment approach, interventionist, year of publication, and dependent measure type, significantly explained heterogeneity in effects across studies. A sensitivity analysis showed these results were generally robust to outliers. We offer possible explanations for the findings and discuss study limitations. Finally, we propose recommendations for future research and classroom practice.

Sediment phosphorus composition controls hot spots and hot moments of internal loading in a temperate reservoir
Authors: Albright Ellen , Wilkinson Grace
Published: February 2022

Phosphorus (P) flux across the sediment-water interface in lakes and reservoirs responds to external perturbations within the context of sediment characteristics. Lentic ecosystems experience profound spatiotemporal heterogeneity in the mechanisms that control sediment P fluxes, likely producing hot spots and hot moments of internal loading. However, spatiotemporal variation in P fluxes remains poorly quantified, particularly in the context of sediment chemistry as a controlling variable. We measured P flux rates and mobile sediment P forms along the longitudinal gradient of a temperate reservoir every two months from February to October of 2020. Both aerobic and anaerobic processes mobilized sediment P throughout the year. High flux rates at littoral sampling sites (8.4 and 9.7 mg P m-2 day-1) occurred in late summer under oxic conditions in the overlying water and mobilized labile organic P. High fluxes at the profundal site coincided with hypolimnetic anoxia under ice cover and in mid-summer (11.2 and 17.2 mg P m-2 day-1, respectively) and released redox-sensitive P. Several high fluxes substantially skewed the flux rate distribution, providing evidence of hot spots and hot moments of internal loading. We further scaled the measured sediment P flux rates to representative areas of the lakebed to estimate internal P loads at an ecosystem scale. We found that P release from littoral sites under oxic conditions in the overlying water had an outsized impact on total loads. Our findings demonstrate the importance of considering spatial and seasonal variation in sediment P pools and fluxes in order to more accurately estimate internal loads and identify the dominant biogeochemical mechanisms involved.

Tidal flood and erosion are familiar phenomena in coastal areas that have an impact on the destruction of facilities and infrastructure (water, waste management, drainage) as well as environmental damage which is marked by a decrease in the quality of life of the community. However, the community persisted and chose to stay in the area and the population was increasing from year to year. Community resilience can be seen from several aspects: economic, social, infrastructure, and health. Building community resilience depends on social relationships, networks, and connectedness among communities. This paper reviews and compares the level of community resilience in Portsmouth (UK) and Semarang (Indonesia) to the erosion and flood disasters that hit these regions. With the descriptive comparative method, it is studied how the community's resilience to floods and abrasion is studied. The analysis results show that despite adequate defenses, Portsmouth’s resilience faces a higher economic risk of disasters and the resulting residual risks. Changes that occur on the coast of Semarang City have made people have to carry out a learning process to maintain their lives in the context of adaptation to the social, political, economic, and ecological environment in which the population lives.

Published: February 2022

In production and in everyday life, various heating systems are used. Alternative heating methods have also been used in recent years. One of the sources for the heating system is the Sun. The use of solar energy is of great importance for objects cut off from centralized heat and power supply systems: small villages and auls, farm formations, distant pasture breeding, mobile houses. Heating from the sun, created on the basis of solar panels, is carried out by installing an electric heater. Currently, more and more attention of consumers is drawn to the electrically conductive carbon-based fuel material (carbon). The aim of the study was to study the use of an alternative energy source in the form of solar radiation and carbon thermal flexible material as a heater for heating mobile living quarters of farmers. To carry out the research, a solar station and a heater with a carbon fiber heat-emitting flexible material were installed on the farmer's mobile house. Studies have shown that the proposed system is efficient and in comparison with other systems, such as solar collectors, the system has a number of advantages.
