Association Between Critical-Care Nurses’ Attitudes, Knowledge, and Barriers of Pressure Ulcers With Their Demographical Variables
Authors: Abd-Alameer Master student: Ali Falih , Kadhim Jihad Jawad
Published: October 2023

When the force applied to a particular place of the body exceeds the pressure that the capillaries there can withstand, a pressure ulcer will develop. In some circumstances, even a negligibly little pressure may be sufficient to obstruct blood flow and reduce oxygenation of the surrounding tissues. In patients who are extremely unwell, this can result in the development of a pressure ulcer in as little as two to six hours To assess knowledge, attitudes, and barriers among critical-care nurses on pressure ulcer prevention with their demographical variables  A non-probability (purposive) sampling of (130) nurses working in the intensive care unit has been conducted. The study employed The researcher employed a 30-item self-administrated questionnaire to gauge nurses' level of expertise in pressure ulcer prevention. Age, gender, degree of education, years of experience, and specific guidelines for pressure ulcers were among the features of the study subjects. The 5-point scale was utilized in the attitudes and barriers questionnaire. However, the scoring mechanism for the Likert scale model is not much different from the three-point scales, with greater scores going to attitudes with higher levels of positivity and obstacles.   The current study features a descriptive cross-sectional quantitative design. The study has been carried out between the 1st of November 2022 and the 1st of June 2023 to the assessment of nurses’ knowledge attitude and barriers toward pressure ulcers in critical care units at Al Najaf hospitals.

Introduction: In the setting of pediatric urolithiasis, it is important to determine the presence of any metabolic disorder to prevent new stone formation and to treat the existing stone. With this aim, the urinary excretions of electrolytes and uric acid are usually obtained. Fractional excretion of urea (FeU) has been demonstrated to be useful in the setting of acute renal injury. However it has not been studied in the setting of pediatric stone disease. The objective of this study is to search the importance of FeU in pediatric stone disease and to compare FeU with other urine electrolyte excretions and uric acid excretion.

Materials and Methods: We retrospectively evaluated the laboratory and medical records of 41 pediatric urolithiasis patients whose FeU percentages were studied together with the etiologic work-up. Patients were divided into two groups as microlithiasis and macrolithiasis. Demographic and laboratory data as well as FeU were compared between the two groups.

Results: Twenty-four patients (59%) had stone size less than 3 mms, seventeen patients (41%) had stones larger than 5 mms. Among all patients 20 of them were boys, 21 of them were girls. M/F ratio was 13/11 in microlithiasis and 7/10 in macrolithiasis group. Mean age was 55.8 months in microlithiasis group, wheras 39 months in macrolithiasis group. Mean serum urea, creatinine, sodium, potassium, phosphorus levels and FeNa, FeU and TRP percentages were similar between the two groups. (p>0.05).

We divided the patients according to their FeU percentages as FeU

Aim: In this study, we aimed to determine the differences by performing voice analysis in men with benign pros-tatic hyperplasia (BPH) and discussing it with the literature

Methods: The study included 77 male patients who came to the urology outpatient clinic and were diagnosed with BPH and consult to us for voice analysis. Patients' ages, testosterone, prostate specific antigen (PSA) levels, prostate volumes (milliliters) were recorded. International prostate symptom scoring (IPSS) was applied to the patients. Mild, moderate, severe patients according to IPSS scoring; were classify as group 1, group 2, group 3, respectively. Voice Handicap Index-10 Turkish version (VHI-10) was realized to the patients and the results were saved.

Results: 77 male patients were accepted to the study. The average age was 60. The mean prostate volume of the patients was 41.1 ml. The IPSS score of the patients was 16 on average. The mean VHI-10 scores were 9.14. The mean PSA levels of the patients were 1.43; testosterone levels were 3.04. F0 Hz (mean pitch) values were 157.74; jitter % values mean 0.26; shimmer % values mean 2.42; The mean HNR dB values were 22.91.

Conclusions: Maybe it would be more logical to think that many local factors, hormones and growth factors are efficient in place of a testosterone.

The article examines the theoretical foundations of using web technologies in the training of chemistry teachers. The factors of preparation of future chemistry teachers for the use of WEB technologies during distance learning have been determined. The use of educational WEB-resources enables teachers to carry out purposeful and more effective interaction with students, organize individual educational work, introduce and deepen methodical materials from educational subjects. An analysis of the theoretical works of domestic and foreign scientists was carried out, which indicates that in the context of the study of the quality of education, there is no unambiguous methodology for the development of WEB-oriented educational systems. The use of WEB technologies is growing significantly in all spheres of human life, in particular, this applies to the sphere of education. One of the main reasons for teachers' intensive attention to the problem of implementing WEB technologies is the convenience and ease of use of existing tools for finding, creating, and using educational WEB resources. Using educational WEB resources, it is possible to greatly increase the effectiveness of the educational process, to activate the educational and cognitive and independent activities of students. In the process of his activity, the teacher has to solve tasks related to the search for available educational WEB resources, analyzing them for the feasibility of using them in the educational process and creating his own. First of all, this affects the chemistry teacher, since his profession is closely related to the use of WEB technologies. Chemistry teachers can use WEB resources for distance learning, in class and in extracurricular work. The introduction of WEB technologies into the educational process requires the development and practical use of scientific and methodological support, the creation and effective use of tools and systems of computer training and knowledge control, the systematic integration of these technologies into existing educational processes and organizational structures.

TWO-COMPONENT TERMS-PHRASES IN THE UKRAINIAN TERMINOLOGY OF SUGAR PRODUCTION
Authors:   Pavlo Tychyna Uman State Pedagogical University, Zadoiana Larysa
Published: October 2023

The article is devoted to the linguistic description of the modern Ukrainian terminology of sugar production in the aspect of term formation. Terms and phrases of sugar production are analyzed according to such a criterion as the number of components. Models of two-component terms-phrases are considered. Based on the results of a sample of two-component terms-phrases, it was found that in the texts on sugar production, these terms constitute the most numerous group and are the most productive. This structural type is represented by the following models: "adjective + noun in the nominative case" (Adj + N n. c.); " participle + noun in the nominative case" (Part + N n. c.); "noun in the nominative case + noun in the genitive case" (N n. c. + N g. c.); "numeral + noun in the nominative case" (Num + N n. c.); "noun in the nominative case + preposition in + noun in the local case" (N n. c. + in + N l.c.); "noun in the nominative case + preposition with + noun in the genitive case" (N n. c. + with + N g. c.); "noun in the nominative case + preposition with + noun in the instrumental case" (N n. c. + with + N i. c.); "noun in the nominative case + preposition from + noun in the genitive case" (N n. c. + from + N g. c.); "noun in the nominative case + preposition in + noun in the accusative case" (N n. c. + in + N a.c.); "noun in the nominative case + adjective" (N n. c. + Adj); "noun in the nominative case + numeral" (N n. c. + Num); "noun in the nominative case + preposition on + noun in the local case" (N n. c. + on + N l. c.); "noun in the nominative case + noun in the dative case" (N n. c. + N d. c.); "a noun in the nominative case + a noun in the instrumental case" (N n. c. + N i. c.). The most productively used is attributive model «adjective + noun in the nominative case" (Adj + N n. c.), which is formed on the basis of the genus-species relationship, i.e., a definition is added to the term, which is a generic concept, representing types of the concept and specifies the generic. The terms of this model serve as expressions of lexical paradigmatic relations in the term system, in particular antonyms. Substantive two-component models "noun in the nominative case + noun in the genitive case" (N + N g. c.), "participle + noun in the nominative case" are also productive. A small number of terms are presented by models of prepositional and prepositional structures. Two-component syntactic constructions can be replaced by single words, most often composites, as a result of linguistic economy. So, among the analyzed two-component structural models, the models "adjective + noun in the nominative case" and "noun in the nominative case + noun in the genitive case" and "participle + noun in the nominative case" dominate. Other structural models are less productive.
RELATIONSHIP INFORMATIONAL AND ORTHOGONAL COMPONENTS OF THE RECEIVING ANTENNA SCATTERING FIELD WITH ITS LOAD
Authors:   Institute of radio and information systems (IRIS), Smirnov Evgeny V.
Published: October 2023

Previously, we established that the total scattering field of the receiving antenna includes the information component of the total scattering field and the orthogonal component. Each of these components consists of a main and an additional component. Moreover, only the main information component of the total scattering field participates in the transfer of energy from a plane wave to the antenna load, despite the fact that both components of the total scattering field component have the same amplitude and phase characteristics and they differ from each other only in amplitudes. This work is devoted to the study of the connection between the components of the total scattering field component and the information component of the total scattering field of the receiving antenna with its load. It is shown that the currents that are created in the antenna load by the additional component of the total scattering field and the orthogonal component of the total scattering field cancel each other out, and the resulting current in the receiving antenna load is determined only by the main component of the total scattering field. This explains that, despite the identical amplitude and phase characteristics of the main and additional components of the total scattering field, only the main component is involved in the transmission of information from the plane wave to the antenna load.
DEVELOPMENT OF A SIMULATION MODEL FOR REGULATION OF THE ANGLE OF ROLL OF A QUADCOPTER USING A PID CONTROLLER
Authors:   Moscow Technical University of Communication and Informatics, Belov Nikita V. , Buyanov Boris Y. ,   Moscow Technical University of Communication and Informatics
Published: October 2023

Autopilot systems typically consist of an “inner loop” that provides stability and control, as well as an “outer loop” that handles mission-level objectives such as waypoint navigation. Unmanned aerial vehicle (UAV) autopilot systems are predominantly implemented using a control system with proportional, integral, and differential controllers that have demonstrated accuracy under stable conditions. A simulation model of the angle of roll of a quadcopter based on a PID controller was developed and investigated. The model reflects in two-dimensional space of the angles of inclination of the quadcopter. Several methods for calculating the coefficients of PID controllers are considered and the choice of the optimal one for solving the set task is made. Simulation modeling was carried out to stabilize the quadcopter in roll. For this purpose, a JavaScript page with a virtual quadcopter was written. The constructed simulation model allows you to visually evaluate the oscillations of the aircraft in space, which significantly reduces the time and cost of setting up the PID controller.

He finished the drawing of it however he did not describe the method he applied. The paper tries to reconstruct in brevity the manner of this historical isochronic map. According to Malík's notes three maps (cartograms) were reconstructed. The final work was drawn very thoroughly to the scale of 1: 500 000. In the Atlas of Czechoslovak History (sheet 24, map h) was the map - together with analogous maps of Moravia and Slovakia drawn by the author of this paper - reproduced in colours to the very small scale of 1 : 4 Millions.
Senatorial Estates in Imperial Asia Minor – State of the Question, Methodological Issues and Perspectives on Future Research
Authors: KLİNGENBERG Andreas
Published: October 2023

The wealth and possessions of Roman senators in the imperial period consisted predominantly in land property, as emphasized by Pliny the Younger (epist. 3,19,8). It is mainly epigraphic documents that give us information about the location and sometimes extent of senatorial land ownership. Especially in Asia Minor there is plenty of evidence, of which Helmut Halfmann already compiled quite some in 1979. Since then many new testimonies have been discovered and published. Apart from that, further, earlier published evidence for the land ownership of senators whose origin was not in Asia Minor can be added. However, a systematic study of senatorial land ownership in Asia Minor as a whole is not yet at hand. The paper provides prolegomena to such a study. I thus give an overview of the extent, distribution and background of senatorial land ownership in Asia Minor. Rarely is this property so clearly indicated as in the land register of Magnesia (I.Magnesia 122, c2). Usually only the combination of different inscriptions confirms the identification of senatorial landowners. Therefore, I outline methodological guidelines on how to obtain reliable findings from such information. Landed properties could change owners, senatorial estates often passed into the possession of the emperors, which is much better researched. Important questions relate to continuity of ownership within a family and to the circumstances of changes of possession. In this context, I also discuss how the senators came to their property. Especially in the case of senators from other parts of the Roman Empire, the question arises as to why and how they acquired landed property in Asia Minor.
Evaluation of Genetic Diversity in Strychnos henningsii Selected from Nine Populations in Kenya Based on RAPD Markers
Authors: Kuria Mary Wahu
Published: October 2023

Strychnos henningsii is a traditional medicinal plant distributed throughout the tropical and subtropical areas. It belongs to the family Strychnaceae but formally in the family Loganiaceae. In order to understand the genetic variation across the populations and geographical regions of this plant, RAPD markers were used to assess the genetic diversity in nine populations of this species in Kenya. Two hundred and seventy samples were randomly selected from the nine populations, each comprising thirty individuals. The genetic variation within and among populations was evaluated using RAPD Primers. RAPD markers detected an average of 38.97% polymorphism in all populations studied. The most polymorphic population revealed was Kitui with 75 (55.15 %) polymorphic loci, while Baringo was the least polymorphic population with 25 (25.74%) polymorphic loci detected. The markers also revealed twenty-five specific population loci, which could be responsible for specific population traits. A higher molecular variance was revealed among the population (54%; p<0.001) than within populations 46%; p<0.001). According to Nei’s unbiased genetic matrix, the most genetically close populations were Taita-Taveta and Kitui with the highest genetic identity of 0.955, while Ngong and Baringo populations were the most genetically distant populations with a genetic identity of 0.836. Clustering analysis grouped the nine populations into two groups. Cluster I comprised Kitui, Taveta, Karura, Marsabit, Ngong, Nyeri and Narok. Cluster II consisted of Jirore and Baringo. These results were supported by the principal Coordinate Analysis. However, the clustering analysis did not correlate to the geographical areas of plant collection. The values for genetic diversity (H) and Shannon index (I) obtained from this study ranged from 0.0867-0.1483 and 0.1289 -0.2337, respectively, indicating that a low genetic diversity exists among the S. henningsii genotypes. It is recommended that all existing populations be conserved and further studied conducted using codominance markers to provide more insight into the genetic variation that exists within and among S. henningsii genotypes

The prevalence of eHealth systems in healthcare facilities has experienced significant growth in many countries. Nevertheless, a significant obstacle that has arisen pertains to the usability of the implemented systems. This paper focuses on assessing the usability metrics that are applicable in evaluating eHealth systems in Tanzania’s contexts. Data were collected through questionnaires and interviews at six health facilities in Tanzania. The main participants were the health workers who were using the eHealth system in their routine healthcare delivery, including pharmacists, laboratory technicians, doctors, and nurses in their different cadres. The analysis of the findings was performed to obtain usability metrics and contextual issues by computing confirmatory factor analysis (CFA) using structural equation modelling (SEM) for quantitative data and thematic analysis for qualitative data. The results revealed that 11 usability metrics constructs with 54 items and 5 contextual issues constructs with 18 items were applicable in evaluating the usability of eHealth systems in Tanzania

The wind tunnel with a long working part, designed for experimental solution of problems of energy, civil, industrial construction, as well as assessment of environmental indicators of projected and existing facilities, has been in operation for 50 years. The issues of wind pressure on the projected main buildings and auxiliary buildings, tower cooling towers, coal conveyor galleries of powerful thermal power plants, supports, phases and garlands of insulators of unique power transmission lines in dimensions of 1150 kilovolts (AC) and 1500 kilovolts (DC), issues of snow drifts of electric conversion complexes, warehouses of thermal coal have been resolved. It is shown that with certain wind directions relative to the studied object, the wind pressure in the local areas of the roof and facades can exceed 4 (four) or more times the values recommended by regulatory documents. The aerodynamic parameters of high-rise and unique buildings and complexes have been studied under the conditions of mutual influence of individual buildings in the complex, and recommendations have been developed for the purpose of wind and snow loads on buildings and structures. The results of model studies in the wind tunnel 3-AT-17.5/3 of the UNICON company are the basis for the Temporary Recommendations of the MDS 20-1.2006. Methods have been developed and proposed to reduce the volume of coal dust removal from the surface of open warehouses of thermal coal, as well as from the surface of rock dumps during open-pit coal mining. During the half-century period of technical operation, all non-metallic components of the wind tunnel have become physically obsolete, nodes with movable elements have worked out their resource, which required a deep modernization of the aerodynamic channel.

Published: October 2023

The paper considers the problem of determining the stress-strain state of a thick-walled cylindrical shell subjected to temperature effects. The shell consists of three layers: two layers of heat-resistant concrete and a steel outer layer. The calculation takes into account the continuous inhomogeneity of materials caused by a stationary temperature field, as well as the non-linear nature of concrete deformation. A nonlinear problem with variable elasticity parameters E and ν, solved by the method of successive approximations, is described in the article.

Published: October 2023

A brief analysis of the main causes of emergencies in construction and relevant regulatory documents concerning emergency design situations, emergency loads and impacts is carried out. The methods of determining emergency situations are proposed, based both on the analysis of each accident that has occurred, and on the theoretical analysis of possible emergency situations, which should be carried out taking into account the requirements for ensuring mechanical safety of Federal Law No. 384-FZ. The concepts of survivability and avalanche-like destruction are analyzed, and it is proposed to introduce into the text of this law a requirement for calculating the survivability of structures instead of a provision on accounting for an emergency settlement situation that may arise after the failure of one of the supporting structures.
INTERACTION OF FROSTY HEAVING OF SOILS WITH RETAINING WALLS IN THE MASSIF
Authors:   JSC Research Center of Construction, Alekseev A.G.
Published: October 2023

Assessment of the stress-strain state of the freezing heaving soil behind retaining walls is an important scientific and practical task. Freezing of the soil leads to the development of horizontal normal pressure of frost heaving and deformation of the walls. The article contains a method for estimating the amount of soil heaving deformation in orthogonal planes. A method for estimating the pressure of frost heaving of the soil using the theory of thermoelasticity, acting with vertical and horizontal conjugate freezing of the heaving soil, is proposed. An analytical formula is obtained for estimating the heaving pressure during horizontal freezing of the soil behind the wall, taking into account the nonlinearity according to the hyperbolic law. The components of the pressure on the walls are determined taking into account the effect of frost heaving and thawing of the soil using the theory of ultimate equilibrium. Comparative calculations of the heaving pressure according to the proposed method and the measured pressure are presented in field conditions in Sergiev Posad Moscow region.

The dependence of the natural oscillation frequency of a pinched rectangular plate on the magnitude of uniformly distributed compressive (or tensile) forces applied to all its faces is investigated. The problem is solved using two hyperbolo-trigonometric series satisfying all the conditions of the boundary value problem. A resolving infinite homogeneous system of linear algebraic equations is obtained with respect to a single sequence of coefficients of a series, which contains the natural frequency and intensity of the longitudinal load as parameters. The natural frequency was calculated for a number of values of the longitudinal load up to its critical value. At the same time, an iterative method of finding nontrivial solutions of the system was used in combination with the frequency sampling method (the “shooting” method). It is established that with increasing compressive load, the natural frequency of the square plate decreases according to the parabolic law. Numerical results are compared with the results of other authors.
