Assessment of Ground Penetrating Radar for Pyrite Swelling Detection in Soils
Authors: KhoderAgha Nabil , Assaf Gabriel 
Published: March 2024

Pyrite swelling in soils below buildings is a major issue. It leads to severe deformations in floor foundations. A survey is carried out at a selected site in the city of Laval, Quebec, to assess the usefulness of ground-penetrating radar (GPR) to detect deformations that may be indicative of the presence of pyrite. Four soil samples are taken from the aforementioned site to determine the soil type below the concrete slab. The results indicate the presence of limestone, moor clay, and shale sediments, which are prone to pyrite swelling. The GPR data were collected using the GSSI SIR 4000 with a high frequency antenna and processed using RADAN software. The GPR data indicate the presence of severe deformation in many locations of the concrete slab. The most important wave reflections indicative of pyrite swelling are the rebar reflections, showing interesting pushed-up and dropped-down reflections. These reflections appear in two forms. The first is the attenuated reflections that may occur due to pyrite-rich materials. The second is the high amplitude reflections that occur because of the air void, which can be formed due to heaving the concrete slab because of pyrite swelling. As a result, GPR appears to be an effective method for assessing and mapping the effect of pyrite swelling below concrete slabs. Doi: 10.28991/CEJ-2024-010-03-05 Full Text: PDF

Published: March 2024

Artificial intelligence systems have gained access to various scientific and research fields, especially in the construction industry. The study seeks to confirm the vital role of introducing Knowledge Management (KM) integrated with Artificial intelligence (AI) applications in the projects. It requires qualifying engineers and imposing their current qualifications to achieve the benefits of Integration of AI Applications based on KM processes to perform their professional roles and recognize the need to develop their capabilities through training and development. The field survey was intended only for 85 engineers working on construction projects (public and private sectors). Three axes were clarified to allocate the extent of the sample response and determine the benefits of using the KM process and AI applications for the success of construction projects. The results showed a positive relationship between the demographic variables of the response and the benefit of using the KM process and AI applications and explaining the variance in the regression relationships. Therefore, the study suggests integrating AI applications based on the KM process to achieve business goals and effectively benefit and exchange management, as its use leads to faster and more effective decision-making, especially if the project strategy approves it.

Increasing the efficiency of technical information technologies implementation at various stages of the capital construction project life cycle
Authors: Shilov Leonid , Adamcevich Lyubov' 
Published: March 2024

The article analyzes the existing experience in introducing information modeling technology for a capital construction project at various stages of the life cycle. It is noted that the use of technology is considered at individual stages of the capital construction project life cycle , but there is no mechanism for transition from one information model to another. It was revealed that the rules for maintaining as-built documentation, reflecting not only the actual execution of design and working documentation decisions, but also the actual state of the building structure or its individual elements, are regulated, and the existing approach assumes that the operation of the building will be based on working documentation with changes made to reflect the current state object, i.e. on the basis of as-built documentation.
The feasibility of information model developing with a different set of detail and attribute coating, corresponding to various types of documentation: design, working and executive, is substantiated.
A universal roadmap for the information modeling technologies implementation in a design company has been developed, a proposed structure for storing information models of a construction project has been given, and further steps have been proposed for the implementation of information modeling technologies at subsequent stages of the life cycle of a capital construction project to increase the efficiency of its application.

Published: March 2024

AbstractBlood collection is frequently used for neonatal and juvenile mice in toxicology, developmental, and immunology studies and is often a terminal procedure. However, the use of nonterminal blood collection techniques, including the submandibular and the submental collection techniques described for adult mice, may offer opportunities to reduce animal numbers and refine current methods. The use of the submental technique has not been described for neonatal or juvenile mice. In this study, we compared the submental and submandibular blood collection techniques to determine their suitability for use in neonatal and juvenile mice. Male and female CD1 mice, ages 7, 14, 21, and 28 d, were randomized by sex into submental (n = 16), submandibular (n = 16), or control (n = 8) groups. Each mouse was weighed, bled per its assigned group (or only restrained in the case of control mice), and then decapitated without anesthesia for terminal blood collection. Blood collection volume and corticosterone concentrations were measured. The 2 methods showed significant differences in the volume of blood collected at ages 14 and 28, with the submandibular technique yielding significantly higher volumes. No significant differences were detected in corticosterone levels between the 2 techniques based on age or sex. A subset of mice (n = 8, 2 per age group) were bled via submental or submandibular technique and were evaluated 48 h later for gross and histopathologic evidence of trauma. Seven of the 8 mice showed expected inflammation and healing at the collection sites, with 4 mice having embedded strands of fur in the tissue. These data indicate that the submental blood collection is a viable method for nonterminal blood collection method in neonatal and juvenile mice, especially when smaller amounts of blood are needed.

Мета. Системний пошук раціональних та ефективних рішень по створенню пристроїв для контролю положення та орієнтації плоских деталей взуття за асиметрією поверхонь для організації середовища роботи промислових роботів.
Методика. У роботі використано метод системного, теоретичного та порівняльного аналізів. Теоретичні дослідження ґрунтуються на базових положеннях фізики та технології виробництв легкої промисловості.
Результати. Встановлено, що процес орієнтування об'єктів роботизації один із елементів упорядкування середовища, завдання орієнтування включає елементи контролю положення. Тому контроль положення об'єктів роботизації є невід'ємною частиною упорядкування середовища.
Для орієнтації плоских деталей взуття, поряд з контролем положення деталей за геометричними ознаками, необхідний контроль їхнього положення за асиметрією властивостей поверхонь. Існуючі в приладобудуванні та машинобудуванні прилади для контролю положення плоских деталей по асиметрії властивостей поверхонь неможливо застосувати для більшості плоских деталей взуття, оскільки властивості поверхонь цих деталей мають свою специфіку. Досліджені раніше способи контролю положення взуттєвих деталей по асиметрії властивостей поверхонь складні та ненадійні в роботі, оскільки всі вони є багатоступеневими системами, в яких сигнал, отриманий від датчиків контролю, перш ніж дати команду виконавчому механізму, повинен пройти велику трасу через елемент, що порівнює, підсилювач, виконавчий елемент. Кожен із цих ступенів є складним пристроєм і збій у роботі одного з них призводить до порушення працездатності всієї системи.
Тому необхідно створити нові, більш досконалі та надійні способи контролю, провести їх дослідження, спрямовані на одержання чітких рекомендацій та типових методик розрахунку контролюючих пристроїв.
Наукова новизна. Проведено системний аналіз способів контролю положення плоских деталей за асиметрією поверхонь в різних галузях промисловості, Запропоновано класифікацію способів контролю положення плоских деталей в залежності від їх фізико механічних властивостей. Встановлено, що існуючі способи є малоефективними для плоских деталей взуття і є потреба створити нові, більш досконалі та надійні способи контролю.
Практична значимість. Одержані результати досліджень можуть бути використані при проектуванні пристроїв для контролю положення та орієнтації плоских деталей взуття при їх автоматичній подачі на технологічну обробку.
Pensamiento crítico en la docencia y la práctica de la medicina
Authors: Peguero Rodríguez Eva , Borrell i Carrió Francesc 
Published: March 2024

El presente artículo explica y ejemplifica la definición de pensamiento crítico en medicina y su relación con el modelo científico.
Pensamiento crítico, o mejor aún, cognición educada, consiste en saber identificar un conocimiento basado en evidencias de otro que no lo es, en saber gestionar la incertidumbre en situaciones como la aún actual pandemia de COVID-19. Consiste en buscar la veracidad como método. Y requiere una capacidad de crítica con dosis de escepticismo.
La segunda parte del artículo argumenta la importancia de tener conocimientos basados en modelos. Conocimientos que no creencias. El modelo científico consiste en enmarcar el conocimiento científico en un modelo explicativo que no un modelo mágico ni un modelo justificativo. El modelo científico reconoce sus fortalezas y debilidades, es decir, se aplica de manera crítica, y está obligado a explicar y predecir parcelas de la realidad física, psíquica o social.
En general se asocia el pensamiento crítico a un camino para llegar a la verdad, pero, tal como describimos en el presente artículo, resulta mucho más apropiado considerarlo un camino para rectificar y perfeccionar nuestros hábitos motores y de reflexión, y una metodología para pensar conforme a modelos que expliquen lo mejor posible la realidad y para rectificar sin apenas dolor moral.

Published: March 2024

SCIENTIFIC RELEVANCE. The complexity of standardising immunobiologicals, including bacillus Calmette–Guérin (BCG) vaccines, requires improving the approach to statistical analysis of consistency in their quality indicators. Quality analysis tools include Shewhart control charts, which can be used for real-time and retrospective identification and analysis of trends in the processes of interest.AIM. This study aimed to analyse quality indicators of a BCG vaccine for bladder cancer immuno­therapy using Shewhart control charts to monitor consistency in manufacturing processes and quality testing of vaccines.MATERIALS AND METHODS. The study involved a retrospective analysis of the bacterial concentration, dispersity index, loss-on-drying, and potency data obtained during the quality control of Imuron-vac, a BCG vaccine for bladder cancer immunotherapy, in the past 5 years. As part of the statistical data analysis, the authors calculated the means, investigated the corre­lation between the test results provided by the manufacturer and the quality control results obtained at the testing centre (TC), and checked the distributions for normality. Individuals and moving range control charts were plotted and analysed for each quality indicator.RESULTS. The correlation coefficients (r) ranged from 0.34 to 0.70 for the data submitted by the manufacturer and the data obtained at the TC. Pearson’s goodness-of-fit test showed that the distribution of the quality control results obtained at the TC was normal, with χ² = 14.03 for the dispersity index values and χ² = 4.93 for the loss-on-drying measurements. Shewhart control charts for loss-on-drying and potency data suggested that the production process and/or the testing process deviated from the state of statistical control. Consistency monitoring of the bacterial concentration and the dispersity index showed that the state of statistical control was achieved. The authors established control limits for further real-time monitoring of the dispersity index consistency.CONCLUSIONS. Shewhart control charts are applicable to the quality control of BCG vaccines for bladder cancer immunotherapy at the TC. Continuous monitoring of consistency in quality indicators is needed to improve the standardisation of vaccine production processes and testing methods, as this standardisation will result in high product quality.
Notes on the Hebrew Names of the Planets, as Transmitted by Epiphanius of Salamis
Authors: Rendsburg Gary A. 
Published: March 2024

Abstract
The article analyzes the names of the Hebrew planets, as transmitted by Epiphanius (4th century C.E.). The names for Sun, Moon, Jupiter, and Saturn are self-evident, but the names for Mars, Venus, and Mercury are more difficult to ascertain. The article engages in philological analysis in an effort to elucidate the underlying Hebrew forms of the terms written in Greek characters. Since these forms are not the ones used in rabbinic literature, the author further suggests that these terms may reflect a non-rabbinic stream of Judaism in late antiquity.
