Published: August 2024

In all Countries, road pavements are recognized as one of the most critical structural components. Attention must be paid to the management of maintenance work and its timely execution in order to keep the pavement in good conditions and acceptable service level. Pavement distress check is very beneficial to the capabilities of Pavement Management Systems (PMS). The objective of this research is to connect the PAVER software database to A GIS software in order to perform spatial analysis of pavement condition and develop location-related heat distress maps based on Pavement Condition Index (PCI) values. A visual survey of the research area was conducted to evaluate the type, level, and amount of defect. The PAVER 6.5.7 software was used to calculate the PCI values for each sample unit based on the data collected from the visual survey. The data obtained by the PAVER program was integrated with ArcGIS software 10.4 in order to create heat maps utilizing spatial analysis tools .

The heatmap shows the type maintenance for the study region based on PCI values, with each category of PCI values represented by different colors. Each color on this map represents a different sort of maintenance, with red indicating that the pavement requires rebuilding, yellow indicating rehabilitation, and green indicating preventative maintenance. PCI values over 85 indicate that the pavement is in excellent condition and does not need to be maintained. Using the heat map . In general, the selected roads in Nasiriya city is quite and in acceptable conditions, although there is some patching and weathering practically everywhere, and the road needs to be covered with overlay asphalt layer.

Authors: Mohammed Hasan Hayder 
Published: August 2024

The axial heat conduction in parallel flow microchannel heat exchanger with rectangular ducts was numerically investigated, for laminar, 3-D, incompressible, and steady state flow of water. The governing equations, continuity, Navier-Stokes equations (momentum equations), and the energy equations for the hot and cold fluids were solved by using SIMPLE algorithm with finite volume method and FORTRAN code to obtain the temperature distribution for the two fluids and the separating wall between them.
The results play an important role of the axial heat conduction on the effectiveness in parallel flow microchannel heat exchanger and the factors affecting the axial heat conduction are; Reynolds number Re, thermal conductivity ratio, aspect ratio ? and channel volume. Increasing of Re, , ? and channel volume each separately leads to increase the axial heat conduction and vice versa.

Background: Detection of axillary metastases in breast cancer is critical for treatment options and prognosis. The aim of this study is to investigate the value of radiomic features obtained from short tau inversion recovery (STIR) sequences in magnetic resonance imaging (MRI) of primary tumor in breast cancer in predicting axillary lymph node metastasis (ALNM).
Methods: Lesions of 165 patients with a mean age of 51.12 ±11 (range 28-82) with newly diagnosed invasive breast cancer who underwent breast MRI before treatment were manually segmented from STIR sequences in the 3D Slicer program in all sections. Machine learning (ML) analysis was performed using the extracted 851 features Python 3.11, Pycaret library program. Datasets were randomly divided into train (123, 80%) and independent test (63, 20%) datasets. The performances of ML algorithms were compared with area under curve (AUC), accuracy, recall, presicion and F1 scores.
Results: Accuracy and AUC in the training set were in the range of 57 %-86 % and 0.50-0.95, respectively. The best model in the training set was the catBoost classifier with an AUC of 0.95 and 84% accuracy. The AUC, accuracy, recall, precision values and F1 score of the CatBoost classifier on the test set were 0.92, 84 %, 89 %, 85 %, 86 %, respectively.
Conclusion: Radiomic features obtained from primary tumors on STIR sequences have the potential to predict ALNM in invasive breast cancer.

Published: August 2024

Background: Breast cancer is the most common cancer in women worldwide and in India. There are very few cases of breast cancer with peripheral blood dissemination having acute leukaemia-like blast cells.
Case presentation: Here we present a 44-year-old breast cancer follow-up patient with the presence of leukaemia-like blast cells in peripheral blood. The specific cytochemical staining and immunophenotyping assays on bone marrow biopsy revealed that atypical cells in her peripheral blood were from breast cancer metastasis. A comprehensive workup confirmed carcinocythemia in the present case and systemic chemotherapy and hormonal therapy were planned. However, she died 15 days after the carcinocythemia presentation. Carcinocythemia patients have a poor survival.
Conclusion: Because carcinocythemia cells can mimic leukemic blasts and share morphological features, the patient's medical history and a careful analysis of the feathery border of the smear are needed to make a definitive diagnosis.

The contribution of trees to human well-being cannot be overemphasized. The study assessed the growth characteristics and Slenderness Coefficient (SLC) of Nauclea diderrichii and Terminalia ivorensis two tree species in Forestry Research Institute of Nigeria (FRIN) Arboretum. A complete sampling of all trees encountered in each plantation were counted and their Diameter at breast height (Dbh) and total height (Ht) were measured using Haga altimeter and girthing tape respectively. Basal area (BA) and Volume (Vol) were computed using allometric formulae. The mean Dbh, Ht, BA and Vol of Nauclea diderrichii (5.870.27; 7.65± 0.87; 0.004±0.00; 0.016 ±0.0011); Terminalia ivorensis (26.18±1.00; 12.4±0.338; 0.06 ±0.004; 0.38 ±0.029), implying that Terminalia ivorensis had more substantial growth and larger size. More trees (97.43%) of the total trees encountered in both plantation were in the low SLC > 70 category while the remaining were in the medium to high SLC Class. The correlation matrix shows negative correlation between DBH, BA, Vol and SLC which implies more stable trees in the arboretum. The study recommends selecting logging of the trees in the high SLC class as they are vulnerable to wind throw.

Published: August 2024

Professional learning communities provide ongoing professional development for teachers, where they become learning leaders and actively participate in school improvement. Continuing professional development (CPD) is vital in improving educational outcomes, as its importance has been proven over the years. This article explores the need for professional development of teacher educators in Myanmar and the utility of professional learning communities in improving teacher quality. This study aims to explore a comprehensive understanding of professional learning communities to support the professional development of teacher educators in improving the quality of education. The research questions are: (1) What are teacher educators' perceptions of PLCs' influence on their professional development? (2) Are there any variations in the teacher educator's professional development in professional learning communities regarding their factors? (3) Is there any significant relationship between professional learning communities and the professional development of teacher educators? Quantitative research methods were used in this study. Survey data were collected from 70 participants (teacher trainers) from seven Education Colleges. The analysis shows that when done well, professional learning communities can impact teacher quality. Some research suggests that teacher professional development is closely related to teacher professional skills and school improvement. The collective learning process helps teachers understand the subject better and broadens their knowledge base. This will help improve student performance and school quality in the future. Teachers' professional development in PLCs were similar based on their position and teaching service as teacher educators. However, teachers were significantly different regarding their age and educational qualifications. In this study, teachers had a high level of collective efficacy. There were significant differences among teachers based on their teaching age, position and educational qualification. Lack of time, teacher accountability, leadership skills, and the negative attitudes of participating teachers were the most frequently cited challenges in implementing PLCs. As a result, educators and stakeholders can use these findings to implement professional learning communities.

Rheological properties of porcine organs: measurements and fractional viscoelastic model
Authors: Mishra Aadarsh , Cleveland Robin O. 
Published: August 2024

The rheological properties of porcine heart, kidney, liver and brain were measured using dynamic oscillatory shear tests over a range of frequencies and shear strains. Frequency sweep tests were performed from 0.1 Hz to a maximum of 9.5 Hz at a shear strain of 0.1%, and strain sweep tests were carried out from 0.01% to 10% at 1 Hz. The effect of pre-compression of samples up to 10% axial strain was considered. The experimental measurements were fit to a Semi-Fractional Kelvin Voight (S-FKV) model. The model was then used to predict the stress relaxation in response to a step strain of 0.1%. The prediction was compared to experimental relaxation data for the porcine organ samples, and the results agreed to within 30%. In conclusion, this study measured the rheological properties of porcine organs and used a fractional viscoelastic model to describe the response in frequency and time domain.
