Представленырезультатыэкспериментальныхисследований процессашлакованиясоплового тракта газогенератора (ГГ) ракетно-прямоточного двигателя (РПД) при осаждении конденсированных продуктов сгорания (КПС) на стенки сопла в зависимости от рецептурных факторов, давления и температуры продуктов сгорания, а также конструктивных факторов. Установлено, что КПС, осевшие на стенки сопловой крышки и входной части сопла, образуют вязкую пленку, которая под действием газодинамических сил способна течь по поверхности соплового вкладыша. Установлено, что процесс шлакования соплового тракта имеет пороговый характер в зависимости от температуры продуктов сгорания. При температурах ниже 1500 К шлакование сопловых отверстий практически отсутствует. При температурах, превышающих 1520 К, интенсивность шлакования сопловых отверстий резко возрастает, достигает максимума при 1600-1800 К.

Разработано аналитическое уравнение состояния (УрС) реального газа для азота. Проведена проверка области применимости УрС в широком диапазоне плотности (от 0 до значения в тройной точке) и температуры (от 100 до 5000 К). Полученное УрС внедрено в газодинамическую программу для расчета многомерных турбулентных реагирующих течений. С использованием нового УрС проведены расчеты истечения плотной затопленной турбулентной струи криогенного азота в камеру, заполненную азотом при нормальной температуре. Проведено сравнение результатов расчетов с экспериментальными данными по изменению плотности вещества в струе. Получено удовлетворительное согласие результатов. Разработанное УрС позволяет разделять области жидкости и газа по локальным мгновенным значениям плотности и температуры в струе без применения модели двухфазного течения.

Экспериментально определены энергии сгорания ряда новых мезоионных пятичленных гетероциклических соединений арилазасиднонов и арилазасидноиминов, содержащих донорные и акцепторные заместители в разных положениях фенильного кольца. Калориметрические измерения энергий сгорания выполнены на прецизионном автоматическом калориметре сжигания с изотермической оболочкой (конструкции лаборатории термодинамики энергоемких соединений ФИЦ ХФ РАН), разработанном специально для сжигания энергоемких соединений. При достаточно большом объеме бомбы (210 см64 ) калориметр имеет невысокий энергетический эквивалент (550 кал/К), что позволяет использовать небольшие количества высокоэнергоемких веществ в опыте и тем самым снизить опасность перехода горения во взрыв. На основе полученных величин рассчитаны энтальпии сгорания и образования в стандартном состоянии потенциально энергоемких нитроарилпроизводных 1,2,3,4-оксатриазолий-5-олатов и 1,2,3,4-оксатриазолий-5-аминидов. Оценено влияние электронных свойств арильного заместителя. Установлено, что вклад азасидноиминового фрагмента дифенильных производных составляет -189 ккал/моль. Расчетные величины для вклада азасиднонового цикла зависят от положения и природы заместителявбензоле,ипоэтомузначениевкладалежитвинтервалеот-105до-126ккал/моль.Наосно-ве полученныхданных по энтальпиям образования производных 1,2,3,4-оксатриазолов и установленных из них величин по вкладам фрагментов возможно прогнозирование термохимических характеристик гипотетических соединений с азасидноновыми и азасидноиминовыми фрагментами.
Geodata collection and visualisation in orchards: interfacing science-grower data using a disease example (European canker in apple, Neonectria ditissima)
Authors: Buhrdel Juliane , Walter Monika , Campbell Rebecca E.
Published: December 2020

The collection and visualisation of data in orchards are important for management of many orchard processes, including pests and diseases. We present methods combining visualising data with efficient, accurate, standardised data collection, using European canker in apple orchards as an exemplar. Using grower-collected current and historical disease data, we investigated Environmental Systems Research Institute (ESRI) ArcGIS tools to analyse and visualise data. Historical data were collected by growers on paper and current data, also collected by growers, using Survey123. ArcGIS Pro was the operating software for analysis, and ArcGIS Online, Web Maps and ArcGIS Dashboards, for visualisation. Data collection, summarising and visualisation were more efficient using Survey123, than paper collection and subsequent data entry. Higher quality data, including spatial location of the disease, informed disease patterns. A standardised geodatabase enabled efficient data querying and analytics to understand disease distribution and temporal dynamics. This study exemplars a standardised disease and pest database to benefit both scientific and industry data management. Geodata collection, combined with visualisation, facilitates the use of data to understand disease and pest dynamics. These techniques offer opportunity for a cohesive industry approach to area-wide disease and pest monitoring and management, integrating previously disparate datasets by using location.

The introduction of monographs on new types of herbal substances, which were not included in the previous editions of the State Pharmacopoeia of the Russian Federation (Ph. Rus.), and the introduction of the new powder dosage form of herbal medicinal products require alignment of requirements for the degree of fineness of medicinal products. The aim of the study was to compare Russian and foreign pharmacopoeial requirements for the degree of fineness of herbal substances and herbal medicinal products. The analysis demonstrated that in the case of cut herbal substances and powder, the Ph. Rus., XIV edition, establishes limits for the percent of particles that pass through and particles that are retained by a sieve with a specified pore diameter. In the case of whole herbal substances, the Ph. Rus. establishes limits for the percent of particles that pass through a sieve with a specified pore diameter. The monographs of the world leading pharmacopoeias include general requirements for the size of particles in all powders produced from chemically synthesized substances, as well as from naturally occurring and mineral substances, while individual monographs have no requirements for the degree of fineness of herbal substances. The national pharmacopoeias of the Eurasian Economic Union member states also include requirements for the degree of fineness of herbal substances, but they are not sufficient. The results of the analysis of the established limits demonstrate the need to change the controlled size of small and large particles for some types of herbal substances.
Validation Parameters as Applied to Methods for Quantification of Microorganisms in Medicinal Products
Authors: Buylova I. A. , Gunar O. V
Published: December 2020

Validation/verification of microbiological methods is a prerequisite for quality control of non-sterile drugs. However, the use of existing procedures for validation/verification of analytical methods is challenging, since a number of factors, such as microorganism distribution in the sample, cell morphology, and metabolic activity of microorganisms contribute to the error in microbiological testing.

The aim of the study was to assess the feasibility of using the microbiological method validation parameters for validation/verification of the agar plate method.

Materials and methods: 18 non-sterile medicinal products were used in the study. Experiments included determination of antimicrobial activity. The quantification of viable bacteria, yeasts and moulds was performed using the modified pour plate method. The statistical processing of the obtained results was performed using Microsoft Excel 7.0 and Statistica 8.0.

Results: the paper provides the results of quantitative determination of test microorganisms inoculated into non-sterile drugs. The results were obtained as part of validation/verification of the agar plate method of the State Pharmacopoeia of the Russian Federation, XIV ed.

Conclusions: the validation/verification of the test method for isolation and quantification of microorganisms revealed no deviations of the study results from the established acceptance criteria. This proves the feasibility of using the following validation parameters: accuracy, precision, robustness, and limit of quantitation when validating new methods for quantitative determination of microorganisms or verification of previously validated methods.

O PROCEDIMENTO DE CONSTRUÇÃO DAS VARETAS DO PROMPTUARIO DE JOHN NAPIER (1550-1617)
Authors: Sales Ribeiro Pedro Henrique , Souza Cavalcante Davi , Costa Pereira Ana Carolina
Published: December 2020

Ao longo de diversos períodos históricos, o desenvolvimento do conhecimento matemático se deu, entre outros motivos, a partir das carências de determinados povos e culturas, e um dos momentos históricos em que isso ocorreu, foi na Idade Moderna que, ao romper com os padrões estabelecidos anteriormente, impôs novas necessidades, incluindo, entre tantas outras, a de se conseguir calcular de forma mais ágil e eficaz. Assim, durante a revolução cientifica, diversos tratados que continham instrumentos matemáticos focados em resolver essa questão, foram publicados. Entre estes tratados, podemos destacar o Rabdologiae, Seu Numerationis Per virgulas..., publicado em 1617 pelo matemático escocês John Napier, e que aborda três instrumentos para cálculos, incluindo o Promptuario. Dessa forma, essa pesquisa tem o objetivo de apresentar o processo realizado pelo autor, para a construção física de uma parte importante deste instrumento, e para esse propósito, nos valemos de uma metodologia qualitativa adjunta a uma pesquisa documental, já que utilizamos um documento original, em sua versão traduzida para o inglês por William Frank Richardson em 1990 e que está contida no livro The Life and Works of John Napier, publicado no ano de 2017. A partir disto, podemos apresentar as etapas de construção das varetas do Promptuario descritas por Napier, bem como compreender o motivo de determinadas exigências que foram postas por ele. Portanto, após compreender o procedimento de construção do instrumento, e reconhecer os aspectos e conhecimentos matemáticos, especialmente geométricos, que são mobilizados, concluímos que é possível incorporar essa operação em uma proposta de interface entre ensino e história da matemática.

Traffic-spatial analysis of road-rail crossings on state roads in the Republic of Serbia
Authors: Obradović Marijana , Jevremović Sreten , Trpković Ana , Milosavljević Miloš
Published: December 2020

The crossings of railway and road can represent a great danger, especially in the case of poor design of these crossings, lack of management measures and inadequate provision of road crossing. Such situations are common on the road network of the Republic of Serbia. Namely, more than 50% of all road crossings on state roads in the Republic of Serbia are not adequately equipped and provided with traffic signalization and road equipment. It is evident that this problem requires timely measures and finding an adequate solution in order to efficiently implement road and rail traffic and reduce the risk of negative effects. This situation also results in the occurrence of traffic accidents at road-level crossings, the number of which has not decreased over the years. In this paper, the traffic-spatial analysis of road-rail crossings on state roads in the Republic of Serbia is performed, which includes a total of 245 road-rail crossings. The analysis was conducted in order to determine the existing situation and identify deficiencies in the network, on the basis of which adequate design and management measures will be proposed to improve the existing condition.
ANALISIS EKSTENSIFIKASI BARANG KENA CUKAI TERHADAP KANTONG PLASTIK DI INDONESIA
Authors: Gultom Eva Nikita
Published: December 2020

The consumption of plastic bags in modern life is growing very rapidly, causing a high level of dependence. In fact, this increase does not go hand in hand with the handling of plastic waste. Indonesia is statistically ranked second as a producer of plastic waste heading to the sea after China. As anticipation, the Government through the Ministry of Finance has proposed a policy of collecting excise on plastic bags. Based on these things, with a qualitative approach, this study aims to analyze the extensification of excisable goods in plastic bags and provide input on the policy of using plastic bags that will be implemented in Indonesia. The results of the study concluded that the idea of extensification of excise on plastic bags is feasible to be considered considering the use of plastic bags that meet the characteristics of excisable goods and the potential revenue generated. In this case, the government can benchmark the implementation of plastic excise levies in other countries. The data collection method uses secondary data through literature studies which cause limitations in the study so that further research is needed.

An Examination of the Links between Technology, Culture, and Reading Proficiency: A Study of the Programme of International Student Assessment (PISA)
Authors: Schenck Andrew
Published: December 2020

This study was designed to
investigate the relationship between culture, technology, and reading. Reading scores
from the Programme of International Student Assessment (PISA) were obtained
from 41 countries and compared to: digital device use in the classroom, method
of digital device use in the classroom, and digital device use outside the
classroom. Results suggest that either no use or extensive use of technology improves
overall reading scores. Cultural characteristics such as assertiveness or low institutional
collectivism in some countries appear to mitigate this effect, decreasing the impact
of technology on reading. Teacher control of technology had the highest impact
on reading performance. Finally, as the use of technology
outside the classroom increased, reading proficiency tended to decrease, with
the exception of the Anglo cultural group.
Know Thyself: Insight Moderates the Relationship between Goal-Concordant Motivation and Positive Emotions
Authors: Kirk Robert , Oetjen Danielle
Published: December 2020

Motivation is a fundamental component of human development. Psychologists have examined the link between motivation and emotion for decades. To our knowledge, this study is the first of its kind to focus on potential moderation effects of private self-consciousness on the relationship between goal-concordant motivation and subjective well-being. We surveyed 433 participants between the ages of 18-89. Findings extend previous research showing age differences in goal concordance (specifically, introjected motivation) and that goal concordance predicts all aspects of subjective well-being. Novel findings demonstrate that private self-consciousness (specifically, insight) successfully moderated the association between goal-concordant motivation and positive emotions.

Published: December 2020

The use of a computer and internet connection allows high school and university students to access more relevant information. However, there is no consensus on the effects of the use of these tools on academic results. This work evaluates the impact of computer and internet at home on the results of the Saber 11 test, a national exam taken by all students finishing their secondary education in Colombia, between 2017 and 2019. This impact was estimated from a pooled two-stage least squares (pooled 2SLS) model, applied to data from 1.578.460 Colombian high school students. We found that computer and internet at home had a positive impact on English language performance in the Saber 11 test in Colombia. This work allows a better understanding of the technological effects on educational achievement and provides information for the design of public policies for education in developing countries.

Deconstructing Cervantes and Dickens in Kathy Acker's Don Quixote and Great Expectations
Authors: Gattan Shannan Dijla
Published: December 2020

السرقة العلمية و الاصالة هما قوتان متعاكستان في اي مجال وخاصة المجال الاكاديمي, و لطالما كانتا الشغل الشاغل للكتاب  والباحثين و الدارسين. وهناك دراسات عدة سلطت الضوء على هذه المسألة. لكن الكاتبة كاثي اكر قلبت الموازين في كتاباتها وخاصة في روايتيها  "دون كيشوت"   وتوقعات عظيمة"

  إن نقطة الانطلاق في هذا البحث هي ما الذي يجعل كاتبة لامعة مثل كاثي اكر "تسرق" عنوانين لأثنين من أشهر النصوص لأشهر كتاب مثل سرفانتس و ديكنز, لماذا فككت تلك الروايات لكي تشكل رواياتها.

      وبما ان اللغة  تعد وسط غير ثابت فليس للنص الأدبي معنى خاص وهذا يعني ان التفكيكين لا يركزون على ما الذي قيل بل على كيف قيل .

      ركز هذا البحث على الطريقة  والغرض وراء تناول روايتين  لكتاب ذكور على يد روائية معروفة على الصعيد الشخصي بعذابها من الرجال فضلاً عن كونها معروفة  بكفاحها المطول كي تنال حقوقها  (حقوق المرأة)  في مجتمع ذكوري.

1960  هي ولادة الحركة التفكيكية وفي 1970  أصبحت مذهب نقدي بارز في الأدب. ومن أهم زعماءها هم جاكوز دريدا وبول دي مان و رولاند بارث و مايكل فوكولت . قد اعطت التفكيكية الدور الرئيس للقارئ  (في اي مجال  وليس الادب فقط) كي يقرأ النص بغض النظر عن الغاية المقصودة للمؤلف.

    بالنسبة لما بعد التركيبة post - stracturalist  لا يوجد هناك حقيقة قطعية . بناءً على ذلك ليس هناك قراءة واحدة , بل هناك عدة قراءات وتأويلات  كتعدد القراء. وهذا تحديدا الذي حدث مع قراء كاثي اكر . فهم لم يجدوا سرفانتس او دكنز كما يدعي عنوان رواياتها بل وجدوا فهم وتوظيف كاثي اكر للنصوص الاصلية لأولئك الكتاب الذكور.

Bevacizumab treatment of patients with breast cancer is associated with induction of MYLK.
Authors: Mamoor Shahan
Published: December 2020

Bevacizumab (Avastin) is an approved treatment option by the European Medicines Agency (1) for more than a quarter billion women in the European Union, and despite having its indication withdrawn by the Food and Drug Administration in 2011 is still utilized in clinical trials in the United States (2, 3). We mined published microarray data (4) from the PROMIX trial to understand in an unbiased fashion genes most transcriptionally perturbed by bevacizumab administration and how this interacted with a standard anthracycline and taxane chemotherapeutic regimen, epirubicin and docetaxel. We report here the induction of the myosin light chain kinase MYLK (5) in the primary tumors of women with breast cancer treated with bevacizumab.

Klotho is differentially expressed in primary tumors and brain metastases in humans with breast cancer.
Authors: Mamoor Shahan
Published: December 2020

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes to discover genes associated with brain metastasis in patients with metastatic breast cancer. We report here the differential expression of Klotho, encoded by KL, in the primary tumors and brain metastases in humans with breast cancer. KL mRNA was present at significantly reduced quantities in both primary tumors and brain metastatic tissues as compared to normal breast tissues. These data combined suggest that down-regulation of Klotho is a conserved event during transformation of breast tissues and progression to central nervous system metastasis and further point to potential importance of Klotho repression during progression of human breast cancer.

Language Dysfunction in Schizophrenia: Assessing Neural Tracking to Characterize the Underlying Disorder(s)?
Authors: Meyer Lars , Lakatos Peter , He Yifei
Published: December 2020

Deficits in language production and comprehension are characteristic of schizophrenia. To date, it remains unclear whether these deficits arise from dysfunctional linguistic knowledge, or dysfunctional predictions derived from the linguistic context. Alternatively, the deficits could be a result of dysfunctional neural tracking of auditory information resulting in decreased auditory information fidelity and even distorted information. Here, we discuss possible ways for clinical neuroscientists to employ neural tracking methodology to independently characterize deficiencies on the auditory–sensory and abstract linguistic levels. This might lead to a mechanistic understanding of the deficits underlying language related disorder(s) in schizophrenia. We propose to combine naturalistic stimulation, measures of speech–brain synchronization, and computational modeling of abstract linguistic knowledge and predictions. This orthogonal assessment may be exploited for an objective and differential diagnosis of schizophrenia, as well as a better understanding of the disorder on the functional level—illustrating the potential of neural tracking methodology as translational tool in a range of psychotic populations.
Opening Doors to Open Science and Scholarship for School Psychology Research, Training, and Practice
Authors: Roberson Anthony J. , Farmer Ryan L. , Shaw Steven , Upton Shelley , Zaheer Imad
Published: December 2020

Trustworthy scientific evidence is essential if school psychologists are to use evidence-based practices to solve the big problems students, teachers, and schools face. Open science practices promote transparency, accessibility, and robustness of research findings, which increases the trustworthiness of scientific claims. Simply, when researchers, trainers, and practitioners can ‘look under the hood’ of a study, (a) the researchers who conducted the study are likely to be more cautious, (b) reviewers are better able to engage the self-correcting mechanisms of science, and (c) readers have more reason to trust the research findings. We discuss questionable research practices that reduce the trustworthiness of evidence; specific open science practices; applications specific to researchers, trainers, and practitioners in school psychology; and next steps in moving the field toward openness and transparency.

By using its visual interface, stimuli can be designed and integrated into experiments and surveys without programming, though it can be also customized using HTML, CSS, and JavaScript code. This software would be beneficial for many students and scientists to build and run their experiments and surveys under the situations of homeschooling and remote working. In this tutorial article, we introduce the functions of lab.js Builder and easy-to-use method for it, and also demonstrate the method of building and conducting the practical experiment at the class of the university.
Geometric correction for satellite image of Mosul city using 3D methods
Authors: Hussein Israa , K.Ghazal Nawal
Published: December 2020

The important preprocessing techniques for remote sensing data and geometrical alteration is the geometric correction. In this paper ,it covers two  models which are used in to  three dimensions  the physical model and the projective Transformation for SPOT 2 to determine the geometric correction  of study region of Mosul city. The ground control points are located on SPOT 2 satellite image. These  models are producing  the X residual, Y residual and root mean square error (RMSE) and then comparing the effects of two models.  The X residual for SPOT 2 physical model is lower than X residual for projective transformation at 0.1420, while the Y residual for physical model has higher comparing with Y residual for projective transformation at 0.1143and Total RMSE for SPOT 2 physical model is lower than Total RMSE for projective Transformation at 0.1823. The physical model is superior to Projective model, so that, it is highly recommended to be used for very precise application and not to be replaced by these non-physical models.    For the physical model, it is clearly that, the altitude of the Ground Control Points (or Check Points) does not effect on its individual RMSE, when using  Projective  model  the RMSE for high altitude  was high  ,where at low  altitude it was low too(extreme relationship).

Bartonella quintana infective endocarditis in northern Alberta: A case report
Authors: Kleinman David Ryan , Lam John C , Bacani Julinor , Tyrrell Gregory , Turvey Shannon Lee
Published: December 2020

We present a case of Bartonella quintana infective endocarditis requiring valvular surgery in an Indigenous patient from northern Alberta that was identified months after initial presentation to hospital with undifferentiated laboratory abnormalities. Syndromes caused by B. quintana are often challenging to diagnose due to their non-specific presentation and the difficulty in detecting this organism using traditional culture methods. Additionally, risk factors for B. quintana include marginal housing and alcohol use disorder, which often impede access to health care. Indigenous patients in northern Canada often face worse health outcomes compared with other regions owing to poor economic conditions, substandard housing, and limited access to health care resources. Given that risk factors for B. quintana are prevalent throughout northern Canada and that this infection is difficult to diagnose, we surmise that the prevalence of B. quintana infection is underestimated in northern Canada.
