Authors: (Kadam) Swati P Bhusari , Gajbe Dr. Mrs. Ujwal , Shinde Sharda C , Bhusari Dr Prashant A
Published: December 2024

The study aims to use computed tomography (CT) to investigate sinonasal pathology and anatomic variants in Functional Endoscopic Sinus Surgery (FESS), enabling the exclusion of concomitant pathologies from anatomic variations and related pathologies.

Material and methods: The patients included in this study were individuals with diagnosis of paranasal sinus or any related diseases. This is a prospective observational study. The 100 patients identified for inclusion in the study and detailed history was taken.

Results: A total of 100 patients were included in the study, with a gender ratio of approximately 2:1, favouring males (69 males, 69.00%; 31 females, 31.00%).The predominant age group among patients was 30-40 years, constituting 24% of the total cohort. A significant majority of patients (79%) presented with DNS. Among DNS-positive individuals, right-sided DNS was observed in 44.0%, and left-sided DNS in 35.0%. Concha Bullosa was a common finding in this patient cohort, occurring in 90% of cases. A right-sided predominance was noted, with 40% of patients presenting with right-sided involvement. The highest proportion of patients (36%) displayed grade 4 CT severity. When the clinical diagnosis was compared to the final diagnosis, chronic sinusitis exhibited a sensitivity of 89% but a specificity of only 71.4%, resulting in an accuracy of 87%

Conclusion:

This investigation emphasizes the pivotal role of MDCT in the diagnosis and management of paranasal sinus pathologies. MDCT's superior spatial resolution and ability to distinguish between anatomical variants and disease processes render it the optimal imaging modality compared to conventional radiography. The results indicate a high prevalence of maxillary and anterior ethmoid sinusitis, with significant anatomical variations such as deviated nasal septum and concha bullosa being frequent occurrences among the study population.

Published: December 2024

The advent of ICT in education has allowed teachers to introduce the use of learning resources in new formats, such as video. While this has many advantages, some of the information about how students learn that is obtained by instructors when teaching face to face is lost with the new format. In this paper, we present a visualization and analysis tool to minimize this loss, collecting and then visualizing the digital footprint left by students while learning from video resources, pointing to the existing evidence found in the literature about such data. We also provide an instrument to collect feedback from teachers and other stakeholders regarding both the data and the provided evidence presented to them by the tool. We carry out a limited test to validate its working and present a proposal to expand the analysis and improve on its design. We conclude that the developed application presents a clear picture of the available data, together with interpretations from the literature about what is happening in the learning process, which can lead to improvements in the process. Additionally, the feedback collected from the tool presents opportunities to complement the available knowledge in the field, and thus lead to a better understanding of how students learn from resources in video format and how we can improve on their design and creation.

Authors:   South-West University “Neofit Rilski”, Stamenova Iva
Published: December 2024

The topic of creative skills arouses the interest of a number of methodologists and researchers, developing and testing in practice their ideas aimed at stimulating the development of creative skills in primary school. In the course of working with the students, the urgent need for the implementation and application of specific methodical steps in the performance of tasks on pre-selected works of art was noticed. It is these difficulties, related to the inability to work expediently with the creative task set by the teacher, that necessitated the identification of a didactic model with practical applicability in reading classes. The model was first tested with students in the fourth grade. The stages and sub-stages of which it consists are intended to significantly ease the written creative activity of fourth-graders in working with literary works. Therefore, the article is aimed at tracking creative skills in older students, in order to generally test the usefulness of the model in the performance of individual or group tasks with a creative focus. At a later stage, it is planned to modify it in order to apply it to students from first to third grade, taking into account their age and cognitive characteristics, as well as their literary interests in working with works of art of different genres.

Authors: Ahmad Soran Abdrahman , Mahmood Hersh F. , Fqi Kawa Omar
Published: December 2024

Foam concrete is a significant engineering research topic considering its lightweight, high homogeneity, low cost, and low thermal conductivity (<0.5 W/mK). These reasons enhanced good property become an important achievement and modify the use of foamed concrete. This paper includes a review of the effect of added material to the foamed concrete (coarse fly ash, fine fly ash, and fiber reinforcement) on the elastic modulus of concrete. The results show that the addition of fly ash as a fine aggregate decreases the elastic modulus value (E-value) by 20% compared to specimens without fly ash, while reducing dry shrinkage by 35% when 30% of cement is replaced with fine fly ash of density equal to 1400 Kg/m3, also reducing the heat of hydration by adding 0.15 % polypropylene fiber, increasing the E-value by 14.41 % for a density of 1600 Kg/m3 and increasing the E-value by 65.6% for a density of 1800 Kg/m3. The E-value of foamed concrete is equal to about 0.25 of the E-value of normal weight concrete, and the value of static modulus of elasticity typically varies between 1000 and 8000 MPa in foamed concrete. Also, proposed models given in the literature to predict modulus of elasticity in different situations with different additional materials are given in this paper.

Published: December 2024

This study analyzes the influence of maternal education level on child development, focusing on nutritional status, motor development, and child health. Based on a review of 15 relevant journals, it was found that mothers with higher education levels have better knowledge about nutrition, developmental stimulation, and the importance of immunization, which contributes to more optimal child growth. Conversely, mothers with lower education levels often lack knowledge about healthy eating and disease prevention, which increases the risk of child health issues, such as stunting. Additionally, family economic factors also affect the mother's ability to apply that knowledge. Overall, the increase in maternal education has a positive impact on the quality of children's health and development, which can help reduce the prevalence of nutritional problems and stunting.

Authors: Lawand Jad , Ghali Abdullah , Hauck Jeffrey , Trejo Corona Stephanie , Gonzalez Roberto , Deveza Lorenzo
Published: December 2024

Introduction:

Cervical fusion surgeries are commonly performed to stabilize the spine and relieve pain from various conditions. Recent increases in nontobacco nicotine product use, such as electronic cigarettes, present new challenges because of their unknown effects on spinal fusion outcomes. Our study aims to explore the effect of nontobacco nicotine dependence (NTND) on the success of cervical spinal fusions.

Methods:

We analyzed TriNetX database data for patients undergoing primary anterior cervical diskectomy and fusion, identified by specific Current Procedural Terminology codes, and categorized into cohorts based on a preoperative diagnosis of nicotine dependence, excluding those with tobacco use or dependence. Propensity matching in the ratio of 1:1 was done to control for demographics and body mass index. We analyzed 90-day medical and 2-year implant complications using chi-squared exact tests and univariate regressions within the matched cohorts.

Results:

The NTND and control cohorts comprised 5,331 and 43,033 patients, respectively. Five thousand two hundred thirty-two matched pairs of patients were included from each cohort as shown in Table 1. Our results indicate notable disparities in complications within 90 days postoperation between the cohorts. The NTND cohort had higher risks for opioid use (85.6% vs. 80.3%, P < 0.001), emergency department visits (13.0% vs. 8.40%, P < 0.001), opioid abuse (0.4% vs. 0.2%, P < 0.001), inpatient hospitalizations (20.0% vs. 17.4%, P < 0.001), and sepsis (1.40% vs. 0.80%, P = 0.01). At the 2-year follow-up, increases were observed in pseudarthrosis (14.0% vs. 9.60%, P < 0.001), adjacent segment disease (3.70% vs. 2.20%, P < 0.001), dysphagia (8.90% vs. 6.3%, P = 0.001), and revision surgery (2.00% vs. 1.40%, P = 0.02).

Conclusion:

This study highlights notable postoperative complications in patients with NTND undergoing cervical spinal fusion.

Published: December 2024

This paper discussed the digitization of some analytical solutions of the fundamental equation of non-relativistic quantum mechanics, the Schrödinger equation, in the Python programming environment. The main objective of the work is to automate the solution of several known analytically solvable problems of quantum mechanics and ensure their use in more complex problems. For this purpose, the Python programming environment was chosen, which, due to the large number of libraries and flexibility, is currently widely used in solving physical and mathematical problems. In the program we propose, which is available on the GitHub platform, it is solved easily. The problem of determining the probability of the spatial distribution of an electron in a hydrogen-like atom is discussed. The Schrödinger equation is presented in the spherical coordinate system. The wave function, describing the electron's state, quantized energy values, and probability density, is derived analytically. A recursive function was written in Python to handle the series coefficients defining the wave function. Utilizing relevant libraries, the resulting program constructs electron spatial distribution functions for different excitation levels. The paper then examines two one-dimensional tunneling scenarios and provides the tunneling coefficients in analytical form. A Python program was developed to plot the dependence of these coefficients on the particle's coordinate and energy. All the code is available on GitHub.

No Bose-Einstein Condensation in Closed Systems with Linear Dynamics
Authors:   Physics Institute, Yerevan State University, Stepanyan Varazdat
Published: December 2024

Recently Bose-Einstein condensation has gathered a popularity and interest. An
interesting theoretical phenomenon closely related to BEC and condensation is Frohlich's dynamic
condensation phenomenon, proposed as a reoccurring mechanism in biophysics. This phenomenon
studied classically brings forth a hypothesis that dynamic emergence of condensation requires
nonlinear interactions. Working in the purely quantum regime I show the correctness of the
hypothesis for a broad class of initial states as well as show a way for condensation to emerge
from linear dynamics if the initial state has very large or very long-range quantum correlations.

Tutors' perspectives on the integration of information and communication technology in early-grade teacher colleges in Tanzania
Authors: Kambona Winfrida
Published: December 2024

This study aimed to explore college tutors' perspectives on the integration of Information and Communication Technology (ICT) in teaching pre-service early-grade teachers in teacher colleges in Tanzania. The study was guided by two research objectives: (1) to investigate the professional learning support tutors receive and (2) to examine the factors impeding the integration of ICT in teaching pre-service early childhood teachers in the classroom. The purposive sampling technique was employed in sampling the four teacher colleges and four principals, while the convenience sampling technique was used to sample the 41 tutors who participated in this study. A collective case study design was used to explore participants' perspectives on the deployment of ICT integration in their daily teaching. Data collected from the participants were thematically analysed. The study findings show that the majority of tutors had limited regular professional training opportunities on the integration of ICT in teaching. The study findings revealed several factors hindering tutors from integrating ICT in their teaching, including limited technological resources, lack of technical support, unreliable internet, absence of integration guides, insufficient digital security knowledge, lack of familiarity with learning management systems, low digital competence, and outdated technological devices. The study, therefore, concludes that inadequate integration of ICT among tutors exacerbates limited acquisition of the necessary digital literacy skills among early-grade pre-service teachers. In this regard, the study recommends that the government should engage tutors in regular training on the use of ICT in classroom practices. Furthermore, ICT tools and devices should be available in teacher colleges for tutors to utilise in their instructional practices for pre-service early childhood teachers.
