Актуальность. Для предупреждения обрушений, вывалов угля и породы в подготовительных выработках при ремонтных работах широко применяются специальные скрепляющие материалы и технологии, обеспечивающие повышение устойчивости пород в кровле, угля в боках, заполнение видимых раскрытых трещин, пустот. Технология химического упрочнения успешно применяется на отечественных и зарубежных шахтах уже более 30 лет. Сущность этой технологии заключается в скреплении неустойчивого массива специальными составами. Область их применения является очень широкой. Известно, что наличие вывалов пород из кровли и боков приводят к образованию куполов, значительному увеличению высоты выработок, образованию глубоких отжимов угля в боках. Наличие куполов, вывалов, глубоких отжимов являются местами слоевых скоплений метана в высоких выработках. В связи с этим скрепляющие составы составляют основу новых технологий при ремонте горных выработок, их перекрепке, ликвидации завалов и куполов. Цель: разработка проектных решений и обоснование параметров упрочнения массива горных пород современными скрепляющими составами при ремонте и восстановлении подземных горных выработок. Методы: натурные исследования, статистическая обработка результатов экспериментальных исследований. Результаты. Рассмотрен вопрос применения скрепляющих материалов при ремонте и перекрепке горных выработок. Произведен комплексный анализ различных по основному скрепляющему компоненту скрепляющих составов, учитывающий их характеристики, область применения и требования к оборудованию для производства работ. Выделено восемь основных групп составов. Предложена технологическая схема упрочнения пород кровли и боков на участках сопряжений подготовительных горных выработок с использованием инъекционного упрочнения полиуретановыми составами.

Актуальность исследования обусловлена потребностью в оперативном методе экспериментальной оценки напряженного состояния пласта впереди проводимой выработки, определяемого совокупностью основных факторов выбросоопасности: горным и газовым давлением, а также прочностью угля. Цель: обосновать метод оценки напряженного состояния краевой части пласта в форме отношения текущего и критического значений показателя выбросоопасности с помощью одновременно выполняемых спектрально-акустического и инструментального метода текущего прогноза выбросоопасности. Объекты: склонные к динамическим явлениям угольные пласты подземных шахт. Методы: анализ инструментальных и геофизических методов контроля напряженного состояния призабойного пространства; оценка напряженного состояния с позиций геомеханики твердого тела; инструментальный метод контроля выбросоопасности – по начальной скорости газовыделения и выхода штыба при поинтервальном бурении скважины; геометрическая акустика; геофизический метод контроля выбросоопасности, основанный на спектральном анализе «шума» рабочего органа буровой установки; оценка напряженного состояния краевой части пласта по результатам одновременного контроля инструментальным и геофизическим методом. Результаты. Дана характеристика инструментальных и геофизических методов контроля горного давления и в целом напряженного состояния призабойного пространства подземных выработок. Показано, что для оценки степени выбросоопасности важны не величины горного и/или газового давления, а отношение текущего и критического значений напряженного состояния, которое приближенно определяется тремя основными факторами: давлением вышележащих пород, внутрипластовым давлением газа и прочностью наиболее нарушенной угольной пачки пласта. Обоснована технология такого определения напряженного состояния пласта, включающая поинтервальное бурение скважины в борт выработки на необходимую глубину с длиной интервала в 1 м, на каждом интервале измерение показателя выбросоопасности инструментальным и геофизическим методом. По результатам измерения определяют отношение средних значений текущего и предельного напряжений на участке между фрезой буровой штанги в конце текущего интервала бурения контрольной скважины и геофоном, установленным в борт выработки.

Background: The study of the zootechnical performance of Tilapia cabrae and Oreochromis schwebischi was carried out at the Mbolet fish farm in Lambaréné in Gabon in order to evaluate the growth and reproductive performance of these two species. Methods: For this purpose, 226 fish (113 of T. cabrae with an average weight of 30.55±9.5 g and 113 O. schwebischi with an average weight of 20.64±10.5 g), were distributed in four 6 m2 tanks with two replicates per species for the growing phase which lasted 60 days. For the reproductive phase, 42 selected mature fish, including 6 males and 36 females of each species, were placed in six 2 m2 ponds with three replicates per species for 78 days. Result: The survival rate, the number of reproductions per species and the absolute, relative and system productivities were determined. It was found that the average weight gain, daily individual growth and specific growth rate were significantly (p less than 0.05) higher in T. cabrae, 48.1±5.51 g, 0.8±0.092 g/day and 1.57±0.066% g/day respectively, than in O. schwebischi, 27.11±9.23 g, 0.45±0.15 g/day and 1.38±0.051% g/day respectively. At the end of reproduction, the absolute productivity of T. cabrae (234.75±24.71 larvae/female/egg-laying) was significantly higher (p less than 0.05) than that of O. schwebichi (104.68±46.64 larvae/female/laying). System productivity was significantly higher (p less than 0.05) in O. schwebichi (11.34±2.29 larvae/m2/day) compared to that of T. cabrae (4.12±1.73 larvae/m2/day). Thus, on a fish farm, the use of these species may be possible.
Fullerowski paradygmat (nie)dobrego prawa i jego aktualność „hic et nunc”
Authors: Szadok-Bratuń Aleksandra 
Published: December 2021

The subject of the article is Fuller’s concept of the (not) good law paradigm defined by three notions: “internal morality of law,” “natural law of a formal nature,” and “formal rule of law” — in the perspective of its application in the current legal order of the Republic of Poland. The discourse was conducted in two stages: on a general, theoretical, and axiological levels as well as on a detailed, practical, and praxeological ones.
The epistemological level with its retrospective view bears resemblance of two models: bad law and good law. The first, encapsulated in literary legal fiction, describes eight cases (anti-values) of King Rex’s legislative failures. King Rex is monarch with authoritarian and conservative traits who excludes the system of government based on the proportional cohabitation of three powers — legislative, executive, and judicative — in favour of anocracy, which is a hybrid regime “suspended” between democracy and authoritarianism. The second is a remedy in the form of axiological contours, postulates (values) of good law: generality, promulgation, prospectivity, clarity, non-contradiction, reality, stability, and compliance. These principles of the formal rule of law, contained in the concept of “soft” jusnaturalism, are a specific professional and ethical code for the public authority which constitutes, executes, and applies the law.
The practical-cognitive level refers to subjectively selected examples of abusing the good lawstandard in the Polish legal and administrative order. It shows the omnipotent and simultaneously dysfunctional executive power in the area of governance and administration, aimed at a radical reconstruction of the social and legal system.
Information system for creating a generalized model of complex technical objects
Authors: Konotop Dmytro 
Published: December 2021

Creation of complex technical objects (CTO, such as science-intensive engineering objects, which are characterized by the number of elements and connections equal to 106 and more) – a process containing long subprocesses, complex objects, models, and based on available standards and information technology (IT). It is known from practice that CTO models are created with the help of information systems - components of CALS and PLM-solutions. This process have the following shortcomings: models at different stages of creation of CTO are not completely interconnected; CTO modeling takes place using different components of IT CALS and PLM-solutions, which creates constant difficulties in data conversion and leads to partial or complete loss of model data; there is no automated communication with other CTO models.
A generalized model of complex technical objects is proposed, which based on using the theoretical-multiple approach allows to establish an information connection between the models of the process of creating complex technical objects. The information system of creation of the generalized model of difficult technical objects that allowed automating process of processing and construction of models is developed; to supplement the technology of parallel PLM design and components of information technologies CALS and PLM-solutions for the task of creating models of complex technical objects.
Stabilization of unmanned aerial vehicle on trajectory in high wind conditions
Authors: Burnashev Vitalii 
Published: December 2021

Stationary proportional control laws have been synthesized to ensure stable motion of an unmanned aerial vehicle along a trajectory under the action of a storm wind. We give the values of the regulator coefficients for all sections of the trajectory from the starting point to the landing. Shown are the realizations of wind disturbances and the parameters of the controlled motion of the aircraft under their action. We consider the accuracy of altitude control and the error of the coordinates of the landing site.
The control laws use the values of constant coefficients obtained at five points of the trajectory. Three points are used for the climb phase and one for level flight and one for descent.
We took into account the wind speed as the sum of the three-dimensional turbulent component, the average horizontal component, considering the vertical shear, and discrete vertical gusts. The parameters of the Dryden shaping filters, as well as the vertical shear, are calculated for an average wind speed at a height of 6 m equal to 23.15 m / s. The speed of discrete upward gusts is 40 m/s, and downward -25 m / s.
In such conditions, the unmanned aerial vehicle successfully passes the specified trajectory from the launch to the landing. For thirty realizations of flight simulation, the standard deviation of the landing site error from the wind acting was calculated.

Published: December 2021

Assessment is the process of teachers gathering information about studentsâ€™ learning, including their achievement and behavior in both the cognitive and affective domains enabling teachers to make informed decisions for classroom instruction. The Pre-professional Math Teachers were exposed with various assessment practices during their academic years which were implemented by their Professors across their academic subject and not to exclude Mathematics classes. Assessment was just regarded as a means for â€œgradingâ€ the mathematical skills and knowledge of the students and not to measure what is worth measuring. This study aimed to determine the assessment practices of content faculty, student-teaching supervisors and cooperating mentors of pre-professional mathematics teachers in State Universities in the Cagayan Valley Region in the Philippines It made used of the qualitative-quantitative research method and utilized questionnaires and semi-structured interview. Frequencies, means, standard deviation, and one-way analysis of variance were used. It was found out that Mathematics content faculty used conceptual class discussions or recitations, studentsâ€™ calculator and computer use, routine homework or drills, studentâ€™s use of manipulatives to monitor the learning progress of their students while write up of projects, tests (prelim, midterms, finals), and critique papers are utilized for grading purposes. The Student teaching Supervisors always used standard checklist for demonstration teaching, and post-conference and the Cooperating mentors used formal visit and post conference with the Pre-service Math Teachers for formative assessment in assessing the pedagogical skills of the Student teachers during the practicum period. Formal visits, standard checklists for demonstration teaching, and post-conferences with concerned individuals were utilized by both for summative assessment.

Abstract
Background

Endocytoscopy (ECS) enables microscopic observation in vivo for the gastrointestinal mucosa; however, there has been no prospective study in which the diagnostic accuracy of ECS for lesions that have not yet undergone histological diagnosis was evaluated. We conducted a surveillance study for patients in a high-risk group of esophageal squamous cell carcinoma (ESCC) and evaluated the in vivo histological diagnostic accuracy of ECS.
Methods

This study was a multicenter prospective study. We enrolled 197 patients in the study between September 1, 2019 and November 30, 2020. The patients first underwent white light imaging and narrow band imaging, and ultra-high magnifying observation was performed if there was a lesion suspected to be an esophageal tumor. Endoscopic submucosal dissection (ESD) was later performed for lesions that were diagnosed to be ESCC by ECS without biopsy. We analyzed the diagnostic accuracy of ECS for esophageal tumorous lesions.
Results

ESD was performed for 37 patients (41 lesions) who were diagnosed as having ESCC by ECS, and all of them were histopathologically diagnosed as having ESCC. The sensitivity (95% confidence interval (CI)) was 97.6% (87.7%-99.7%), specificity was 100% (92.7%-100%), diagnostic accuracy was 98.9% (94.0%-99.8%), positive predictive value (PPV) was 100% (91.4%-100%) and negative predictive value (NPV) was 98.0% (89.5%-99.7%).
Conclusions

ECS has a high diagnostic accuracy and there were no false positives in cases diagnosed and resected as ESCC. Optical biopsy by using ECS for esophageal lesions is considered to be sufficient in clinical practice.
