Authors: Modarresi-Alam Ali Reza , Pakseresht Maryam , Khamooshi Ferydoon
Published: January 2024

In this research, the synthesis of novel conductive composites and nanocomposites of the polyaniline (PANI) is reported by the chemical and oxidative insitu polymerization of aniline in the presence of silica- and nanosilica-supported perchloric acid as well as ammonium peroxy disulfate without using a solvent (solid-state condition) at room temperature and Also, changes in polaron mutations under changing conditions are analyzed. The structure, size, and morphology of all samples were identified using FT-IR, UV-Vis, SEM, AFM, and XRD, spectroscopy methods. The conductivity of the samples was determined by using the four-probe technique, Cyclic Voltammetry, and their values were in the range of conductive polymers. According to AFM and SEM images, silica particles have been thoroughly coated by PANI, and the particle sizes of composite and nanocomposite were in the range of 0.5-4μm and 60-90nm, respectively. Also, the X-ray diffraction (XRD) shows that the nanosilica-supported perchloric acid was crystalline whereas the synthesized nanocomposite was semi-crystalline. Furthermore, the SEM, AFM, and XRD results confirm strong core-shell morphology in obtained nanocomposites. The size of the polymer particles is directly related to the conductivity of the polymer. The UV Visible study showed that the effect of polar solvents with high dielectric constant such as DMF and MeOH is more for smaller particles such as nanocomposite. Due to more interaction of solvent with polymer chromophores groups, their effect is stronger. They reduce energy levels and increase energy gap transfer. They increase the number of polaronic transitions. Chloride anion, compared to perchlorate anion (multi-atomic), due to more connection centers and a specific type of connection, remains in the salt polymer structure after work-up with H2O and causes the formation of a two-layer coating and an increase in the coating surface. This issue in XRD causes the broadening of the peak and the amorphous appearance compared to the NSSPA spectrum and prevents the emergence of separate and sharp peaks. Due to the increase in the surface and size of polymer particles in the structure of the composite, the conductivity is slightly higher than that of the nanocomposite. Due to the increase in the surface and size of polymer particles in the structure of the composite, the conductivity is slightly higher than that of the nanocomposite. Therefore, it can be concluded that in resistors that are used to limit a certain amount of electric current, the nanocomposite structure is preferable to the composite structure.

Published: January 2024

We show the existence of families of periodic polyhedra in spaces of constant curvature whose fundamental domains can be obtained by attaching prisms and antiprisms to Archimedean solids. These polyhedra have constant discrete curvature and are weakly regular in the sense that all faces are congruent regular polygons and all vertex figures are congruent as well. Some of our examples have stronger conformal or metric regularity. The polyhedra are invariant under either a group generated by reflections at the faces of a Platonic solid, or a group generated by transformations that are reflections at the faces of a Platonic solid, followed by a rotation about an axis perpendicular to the respective face. In particular, suitable quotients will be compact polyhedral surfaces in (possibly non-compact) spaceforms.

Published: January 2024

Pollution in industrial areas around the world is a significant problem that is worsening day by day. Islamabad is the capital city of Pakistan with a dedicated industrial zone. This study evaluated the heavy metal pollution levels in the soil and water of Islamabad’s industrial area using statistical, geospatial tools as well as their subsequent health and ecological hazards The results show that the soil of Islamabad’s industrial area is highly polluted with heavy and toxic metals. The risk posed by heavy metals to the eco-system was calculated using Ecological risk factor and was found to be above recommended level. Principal component analysis (PCA), Pearson’s correlation and inverse distance weighting interpolation (IDW) revealed that the soil near the steel mills, landfill and marble processing plants is extremely polluted with heavy metals. Health hazards from heavy metal exposure through ingestion, inhalation, and dermal contact were also calculated. The average daily dose for both adults and children follows the trend, ADDING>ADDDER > ADDINH for soil. The hazard quotient and index follow the trend; HI > HQING > HQDER > HQINH except for Co and Ba. Cr posed a moderate carcinogenic risk to children via the three exposure pathways with the value being 4×10− 4. Natural radioactivity levels for Ra-226, Th-232 and K-40 were found to be 25.96 ± 12.50, 15.84 ± 2.59, 469.48 ± 52.38 Bq/kg respectively. The risk to human health from gamma exposure was also evaluated using various radiation hazard indices. Elemental analysis of water samples coupled with geospatial analysis showed that water samples collected near the industrial complexes have elevated levels of metals. The water quality for irrigation was assessed and the water from Islamabad’s industrial area was found to be suitable for irrigation. This study also quantified the health hazards of heavy metals in water through ingestion and dermal contact. The non-carcinogenic health hazards were highest for cadmium, with children having 10 times higher exposure than adults. This study found that the soil of Islamabad’s industrial area is highly polluted with lower levels of natural radioactivity and the water near the industries also has elevated levels of heavy metals.

Authors: Barajas-Solano Andres F. , García-Martínez Janet B , Contreras-Ropero Jefferson E , Lavecchia Roberto , Zuorro Antonio
Published: January 2024

Biomass harvesting and drying represent the most energy-intensive stages in algal biomass processing. Despite the availability of various technologies at the laboratory scale, certain methods, such as centrifugation or freeze-drying, become prohibitively expensive when scaled up. The primary objective of this study was to identify the optimal method for harvesting and drying algal biomass while minimizing the impact on metabolite content, encompassing carbohydrates, proteins, and lipids. To achieve this goal, an I-optimal design incorporating four variables and two levels was employed to determine the most efficient methods. These findings revealed that electroflotation surpasses chemical flocculation as the preferred method for harvesting, while dewatering is more efficient than convective oven drying is. Further optimization efforts indicated that employing low temperatures and extended durations (56°C and 41 hours, respectively) constitute the optimal strategy for reducing moisture in the biomass while simultaneously enhancing the extraction of metabolites. These results present a more sustainable and economically viable approach to harvesting and drying substantial quantities of algal culture, with a diminished impact on metabolite composition.

Published: January 2024

Background: This study investigates the impact of structured patient education and dietary counselling on the quality of life and prevalence of nutritional anaemia in Type 2 Diabetes Mellitus (T2DM) patients. The significance of patient education in chronic conditions and the Health Belief Model's role in influencing behaviour forms the theoretical basis.
Methods: Conducted at a single tertiary care hospital in Jaipur, India, this case-controlled trial involved 200 T2DM patients aged 30 to 65. Participants were divided into intervention (n=100) and control groups (n=100). The intervention group received tailored education on diabetes management and nutritional counselling, while the control group received standard care. Baseline and three-month follow-ups assessed quality of life, perceptions, and nutritional status.
Results: The intervention group demonstrated significant improvements in quality of life, perceptions related to T2DM, and a reduction in nutritional anaemia prevalence. Glycemic control notably improved in the intervention group. Statistical analyses showed significant differences between groups (p<0.05) for various measured parameters.
Conclusion: Structured patient education and dietary counselling significantly enhanced quality of life, mitigated nutritional anaemia, and improved glycemic control in T2DM patients. The Health Belief Model provided a theoretical framework for understanding the impact of interventions on perceptions and behaviours. These findings underscore the importance of incorporating educational and dietary components into comprehensive T2DM management, especially in tertiary care settings, to optimise patient outcomes and quality of life.

Published: January 2024

Background:Recent advancements in tumor microenvironment analysis have significantly impacted immunotherapy strategies, particularly in thyroid papillary carcinoma. This study focuses on the value of habitat-based radiomics for predicting lateral lymph node metastasis, a crucial factor in treatment planning and prognosis.
Methods:The study selected participants with thyroid papillary carcinoma undergoing their first surgical treatment. Criteria included complete clinical data and enhanced CT imaging. Medical images were normalized and resampled for fixed-resolution pixel values. Radiomics features, classified into geometry, intensity, and texture, were extracted using the pyradiomics tool. Feature selection involved Intraclass Correlation Coefficient (ICC) and LASSO regression. Machine learning models such as Support Vector Machine (SVM), RandomForest (RF), and ExtraTrees (ET) were used to construct radiomic and habitat signatures with a specific focus on identifying lateral lymph node metastasis.
Results:The habitat-based models demonstrated high efficacy in predicting lateral lymph node metastasis. The Habitat Signature showed higher accuracy (94.6% for SVM, 94.6% for RF, 91.9% for ET) and Area Under the Curve (AUC) values (0.988 for SVM, 0.961 for RF, 0.982 for ET) compared to the Radiomics Signature, specifically in identifying metastatic nodes. The Habitat model also had superior calibration performance, as evidenced by Hosmer-Lemeshow test statistics in training, validation, and test cohorts. Decision curve analysis indicated the Habitat Signature's potential for significant clinical benefit in predicting lateral lymph node involvement.
Conclusion:Habitat-based radiomics analysis provides an accurate and efficient approach for predicting lateral lymph node metastasis in thyroid papillary carcinoma. This method enhances the predictive accuracy, facilitating better personalized treatment strategies in immunotherapy settings. It offers a promising tool in personalized medicine, especially for planning targeted treatment and assessing prognosis in thyroid cancer patients.

Published: January 2024

The speed of implementation of electric vehicles depends on the level of development of the charging infrastructure, which is subject to ever new requirements, including increasing ease of use and reducing charging time. A solution to the problem could be an introduction of wireless charging of electric vehicles (inductive charging device – WPT). However, in order to produce an effective WPT (without preliminary calculation and modeling the efficiency of the device may not reach 10 %), it is necessary to select the parameters of the coils and simulate the frequency characteristics of the voltage. For this purpose, as part of the implementation of the project to create a mobile charging installation for electric vehicles, the problem of modeling the operation of the WPT has been solved. In accordance with the technical specifications, a coil has been built in Excel, which was used as geometry in Comsol to evaluate the distribution of magnetic fields. To study the frequency characteristics, the CST Studio program has been used. Using these programs, we simulated various methods for implementing the WPT with obtaining frequency characteristics. It has been confirmed that the coupling coefficient increases with decreasing distance between parts of the WPT. Calculations of resonant circuits and the expected efficiency for both types of resonant circuits have been carried out, and it has been concluded that decreasing the distance leads to a decrease in the resonant frequency of the system of connected circuits. The developed model allows us to obtain the values of the circuit capacitances for the formation of resonance, move on to practical implementation and verify the resulting models.
Neural networks as a tool for improving the mathematical model of ship motion
Authors: Pashentsev S. V.
Published: January 2024

Using neural networks opens up great opportunities for studying mathematical models of ship motion. Correction by a network of identified parameters of the selected model should be as adequate as possible to the results of standard full-scale tests defined by the IMO Resolution N 137 of 2002. A mathematical model in displacements is considered, containing 16 parameters that determine the hydrodynamic forces acting on the ship's hull and steering gear, and is the source of a data set for training the network by randomly varying the parameters and subsequent computer testing. The standard maneuver is a steady-state circulation with fixation of the maneuvering elements: diameter, linear velocity, drift angle and angular velocity of rotation. Improving the quality of the model has consisted of changing its parameters and minimizing the mean square errors of the values of the maneuvering elements obtained during testing. For these purposes, a neural network with 16 inputs (model parameters) and four outputs (maneuvering elements for steady-state circulation) has been built. The data set for training the network was obtained using a program developed by the authors and intended for calculating parameters and conducting maneuver tests. A tanker with a displacement of 30,000 tons was chosen as a test object. Various options for network architecture and tools for working with it have been considered; the Statistica Neural Nets (SNN) software environment and the ANN package in the SciLab environment have been used. Comparative assessments of the results of working with these tools have been given.

Authors: Kandrokov R. Kh. , Erina Ju. S. , Burmatnov V. V.
Published: January 2024

The biochemical composition, physical and technological properties of amaranth grain determine the possibility of its use to improve the consumer properties and nutritional value of bakery products. The obtained experimental results of the acidity and moisture content of samples of dough pieces with the addition of wheat-amaranth bran (5–15 %) and a control sample of wheat dough with 5 % content of wheat bran are within the normative values established in the standards. The addition of 5, 10 and 15 % wheat-amaranth bran improves the nutritional value of the finished product due to the high content of protein, micro- and macroelements, and highly unsaturated oil in the seeds, which contains squalene. Adding wheat-amaranth bran does not change the structure and properties of bread. The resulting samples of tin bread containing 5, 10 and 15 % wheat-amaranth bran have a smooth surface without any special deformations, a soft, elastic crumb, uniform thin-walled porosity without breaks; the taste and smell correspond to this type of wheat bread. The most pronounced taste and smell of wheat bread with 5 % wheat bran content is in tin bread containing 15 % wheat-amaranth bran. The physicochemical parameters of wheat-amaranth test samples, with the exception of moisture and acidity, do not exceed the values of the control sample. Based on the results of the research, technology for preparing enriched wheat pan bread with the addition of wheat-amaranth bran in amounts of 5, 10 and 15 % has been developed.

Published: January 2024

Lipases have been used in industrial processes as biocatalysts for transesterification reactions. The synergism between enzymes and magnetic properties may be reached by using magnetic nanoparticles (MNPs) as support to immobilize them in aggregate structures, denominated by magnetic crosslinked enzyme aggregates (MCLEA). One of the advantages of such supports is the possibility of using magnetic separation for enzyme recovery, reducing costs and allowing reuse in continuous systems. Here, porcine pancreatic lipase (PPL) was immobilized onto functionalized magnetite support (Fe3O4-APTS) with a protein binding efficiency of 78.84%. Physical and chemical properties of the nanoparticles and immobilized lipase were characterized by X-ray diffraction (XDR), transmission electron microscopy (TEM), infrared spectroscopy (FTIR), dynamic light scattering (DLS), zeta potential, vibrating sample magnetometer measurements (VSM), and 57Fe Mössbauer spectroscopy. The immobilized lipase additionally exhibited improved stability across wide pH and temperature ranges compared with free lipase. The immobilized derivate also attained good reusability, maintaining 61.37% of its initial activity after 6 reaction cycles. Through magnetic behavior and also because of its surface modification to crosslinking the enzyme, the MCLEA produced in this work has enhanced the biocatalytic activities of PPL.

THE CASE OF SCHELLING’S LIBERTARIAN ANARCHISM. A PHENOMENOLOGICAL ANALYSIS OF INSURMOUNTABILITY OF THE PARTICULAR WILL IN THE YEARS 1809-1810
Authors:   Charles University, RODRÍGUEZ JUAN JOSÉ ,   University of Wuppertal
Published: January 2024

This paper refers to the connection between the metaphysical duality of ground and existence and inner dynamic of the particular will of man. We will analyse how the metaphysical monism, which Schelling attributes to Spinoza and later to Hegel, is responsible for the abolition of the freedom of the human individual, because it does not account for the existence of evil, and consequently reduces it to the existence of a higher order reference system that over and predetermines the individual (1). We will first scrutinise the principles of separation and union, ground and understanding from the human point of view, namely as the will of ground and love, as particular and universal will (2). The will of man reveals itself as the culmination and model of the will that permeates nature, an essential aspect of the process of God’s revelation and becoming. The link between the principles of separation and union shows us the difference that Schellingian thought establishes between man and God, the real and the ideal. While God, or the purely ideal principle, precedes the separation in a logical-ontological sense, the will of man remains always in an indissoluble tension between the principles, since it is unable to overcome the opposition between good and evil that is characteristic of freedom. The good remains one of the results of human freedom and thus of the particular will of man. The good lies for Schelling not in the simple actualization of the general, but in the moment ineradicable particularity needed for the attainment of a real and effective principle (3). It is to this insurmountability of the particular will in the process of the constitution of man that our proposal of Schelling’s libertarian anarchism refers. The connection of this thesis with the critique of the State is also discussed (4).

PET/CT Examination of Teratomas after Stem Cell Transplantation for a
Spinal Cord Injury: A Case Report
Authors: Chi Xiao-tong , Tian Jun , Zhao Xiu-yi , Zhang Xiao-yan , Xu Chen , Deng Kai
Published: January 2024

Background::

In clinical practice, stem cell transplantation has become an effective method for treating spinal cord nerve injury. Up to now, there has been no
report on teratoma caused by transplanted stem cell’s abnormal differentiation in the clinic, especially in the analysis of imaging manifestations.
Therefore, this article aims to analyze the PET/CT imaging manifestations of teratoma caused by stem cell transplantation to improve the imaging
diagnosing capability.

Case Presentation::

A patient with a spinal cord injury who had received a stem cell transplant was examined by PET/CT on September 10th, 2020. The PET/CT
images of the lesion showed irregular mixed low density on the right side of the erector spinae muscle area at the level of the cervical 3-5 vertebral
body, with a maximum cross-section of 9.1×3.9 cm. The 18F-FDG metabolism of the lesion was increased, and the maximum standard uptake value
(SUVmax) was 10.7. The boundary was unclear with the third cervical vertebra and cervical 3 and 4-level vertebral plates. Based on the patient’s
medical history, the lesion was diagnosed as an abnormal proliferative tumor, which was consistent with the pathological examination results.

Conclusion::

To date, there have been no clinical reports on teratomas caused by stem cell transplantation for spinal cord injury at home or abroad. This case
report enhances the knowledge of the diagnosis and treatment methods of this type of disease and confirms the diagnostic value of PET/CT
examination.
Neural Phonology A Multisensory, Multicognitive Approach to its Enhancement in Teaching Pronunciation
Authors: Odisho Edward Y.
Published: January 2024

As a reaction to the pedagogical needs of adult learners in mastering speech sounds and sound phenomena unfamiliar to their L1 phonology, there surfaced a pressing need for a radical change in the overall approach to teaching them. A transition had to be gradually implemented in the form of a multisensory (auditory, visual, tactile-kinesthetic) strategies to be propped up with a set of multicognitive ones (e.g. think, associate, analyze, synthesize, memorize) in lieu of the traditional audiolingual one. During the implementation of such strategies for a few years, a fully-fledged approach emerged and titled as: Multisensory, Multicognitive Approach to Teaching Pronunciation (MMA). Further classroom experience with MMA, led to the reconsideration of the linguistic domain of phonology for theoretical and applied purposes and recognizing it in two sections i.e., linguistic phonologyvs. neural phonology. Below are a few reasons for introducing neural phonology. First, traditional phonology barely refers to the role of the brain in internalizing additional phonological constituents when targeting L2/FL as adults. Second, teaching phonology and the mastery of unfamiliar sound units/features to learners of L2/FL has been conventionally attempted in a unisensory(monosensory) manner, the auditory sense in this case, which tends to be less efficient and effective with many adults. Third, in real classroom situations there seems to be greater need to diversify and refine the sensory and cognitive strategies/techniques in teaching both sections of phonology, especially the neural one. Fourth, emphasizing the two sections further enhances the overall pedagogical and didactic worth of MMA.

This paper provides an overview of gratitude as a concept and as a mind-body-spirit practice, impacting health and human functioning throughout the lifespan, that can be integrated into daily life to great benefit at no cost. Current society is rife with increases in stress, anxiety, depression, lifestyle-related diseases, and social isolation. The practice of gratitude and its interrelated pro-social, health-enhancing, resilience-building effects suggest that promoting gratitude from childhood through adulthood may provide much-needed, accessible reinforcement towards optimal health and wellbeing.KeywordGratitude; health; resilience
The Sukaribit Smartphone App for Better Self-Management of Type 2 Diabetes: Randomized Controlled Feasibility Study
Authors: Josefsson Cecilia , Liljeroos Thea , Hellgren Margareta , Pöder Ulrika , Hedström Mariann , Olsson Erik M G
Published: January 2024

Background

A new app, Sukaribit, was designed to enable contact between the caregiver and the patient with the intent to improve self-care and glycemic control (hemoglobin A1c [HbA1c]).

Objective

This study investigated the feasibility of the study methodology and the intervention in preparation for a larger effectiveness study.

Methods

Adults with type 2 diabetes were recruited in this randomized controlled feasibility study with a mixed methods design. The intervention group (n=28) tried Sukaribit for 2 months. They were encouraged to report blood glucose levels and medications, and they received feedback from a physician. The control group (n=31) received standard care. Both groups were evaluated with pre and postmeasurements of glycemic control (HbA1c), diabetes distress, physical activity, and self-care. Feasibility was evaluated against 5 progression criteria regarding recruitment, study methods, and active participation.

Results

Of the 5 progression criteria, only 2 were met or partially met. The recruitment process exceeded expectations, and data collection worked well for self-reported data but not for HbA1c measured with a home testing kit. The participants were less active than anticipated, and the effect sizes were small. Only the number of blood glucose tests per day was positively affected by the intervention, with 0.6 more tests per day in the intervention group.

Conclusions

Recruitment of participants to a future fully powered study may work with minor adjustments. The collection of HbA1c using home testing constituted a major problem, and an alternative strategy is warranted. Finally, the app was not used as intended. In order to proceed with a larger study, the app and study procedures need improvement.

Mobile health (mHealth) apps can play an important adjuvant role in preventing and treating chronic diseases and promoting positive health behavior change among people with obesity, and eHealth literacy skills have the potential to impact mHealth app use.

Objective

The purpose of this study was to explore the associations between the 2 dimensions, access and application, of eHealth literacy skills and mHealth app use among US adults (≥18 years of age) with obesity (BMI ≥30 kg/m2).

Methods

Data were obtained from February to June 2020 using the Health Information National Trends Survey 5. A total of 1079 respondents met the inclusion criteria of adults with obesity and owners of smartphones. Individual associations between mHealth app use and sociodemographic variables were explored using weighted chi-square and 2-tailed t tests. A multivariable weighted logistic regression model was fitted, and adjusted odds ratios (ORs) of using mHealth apps with corresponding 95% CIs were reported across multiple sociodemographic variables. An Ising model-weighted network visualization was produced. A receiver operating characteristic curve was calculated, and the area under the curve was reported with the corresponding Delong 95% CI.

Results

A majority of respondents were female (550/923, 59.6%) or non-Hispanic White (543/923, 58.8%). Individuals in households earning less than US $50,000 comprised 41.4% (382/923) of the sample. All sociodemographic variables were found to be univariately significant at the 5% level, except employment and region. Results from the multivariable weighted logistic regression model showed that the adjusted odds of using an mHealth app are 3.13 (95% CI 1.69-5.80) and 2.99 (95% CI 1.67-5.37) times higher among those with an access eHealth literacy skill of using an electronic device to look for health or medical information for themselves and an application eHealth literacy skill of using electronic communications with a doctor or doctor’s office, respectively. Several sociodemographic variables were found to be significant, such as education, where adjusted ORs comparing subgroups to the lowest educational attainment were substantial (ORs ≥7.77). The network visualization demonstrated that all eHealth literacy skills and the mHealth app use variable were positively associated to varying degrees.

Conclusions

This work provides an initial understanding of mHealth app use and eHealth literacy skills among people with obesity, identifying people with obesity subpopulations who are at risk of a digital health divide. Future studies should identify equitable solutions for people with obesity (as well as other groups) and their use of mHealth apps.
Prediction of Mild Cognitive Impairment Status: Pilot Study of Machine Learning Models Based on Longitudinal Data From Fitness Trackers (Preprint)

BACKGROUND

Early signs of Alzheimer disease (AD) are difficult to detect, causing diagnoses to be significantly delayed to time points when brain damage has already occurred and current experimental treatments have little effect on slowing disease progression. Tracking cognitive decline at early stages is critical for patients to make lifestyle changes and consider new and experimental therapies. Frequently studied biomarkers are invasive and costly and are limited for predicting conversion from normal to mild cognitive impairment (MCI).

OBJECTIVE

This study aimed to use data collected from fitness trackers to predict MCI status.

METHODS

In this pilot study, fitness trackers were worn by 20 participants: 12 patients with MCI and 8 age-matched controls. We collected physical activity, heart rate, and sleep data from each participant for up to 1 month and further developed a machine learning model to predict MCI status.

RESULTS

Our machine learning model was able to perfectly separate between MCI and controls (area under the curve=1.0). The top predictive features from the model included peak, cardio, and fat burn heart rate zones; resting heart rate; average deep sleep time; and total light activity time.

CONCLUSIONS

Our results suggest that a longitudinal digital biomarker differentiates between controls and patients with MCI in a very cost-effective and noninvasive way and hence may be very useful for identifying patients with very early AD who can benefit from clinical trials and new, disease-modifying therapies.

The concepts of retention and adjustment emerge as strategies to overcome the challenges associated with cultural transfer in metaphor translation. Metaphor retention is necessary because it ensures the retention of the imagery and meaning conveyed in the original text. Metaphor adjustment aims to translate culturally appropriate metaphors to the target text and avoid misunderstandings. This study seeks to explain the patterns of metaphor retention and adjustment in English novels translated into Indonesian, focusing on analyzing the form and meaning of metaphors. This research relies on the theory of translation retention proposed by Venuti (2008) and the theory of translation adjustment proposed by Eco (2013). The methodology used in this study is based on the theoretical framework proposed by Williams and Chesterman (2014), which places significant emphasis on the examination of linguistic elements contained in the source text as the main stage in translation research, followed by a comparative analysis conducted between the source text and the target text. The data used in this study consists of phrases, clauses, and sentences that have metaphorical features. The data were collected using the Metaphor Identification Procedure VU University Amsterdam (MIPVU). The data were categorized based on Halliday's (1985) grammatical metaphor framework, which focuses on noun, verb, and adjective metaphors. The collected metaphor data were then analyzed using the notions of retention and translation adjustment derived from Sajarwa's (2021) research. The study's findings show that noun metaphors dominate metaphor retention and adjustment. Metaphor retention occurs when the form and meaning of the metaphor do not change, while metaphor adjustment occurs when the metaphor's form changes and the metaphor's meaning does not change.

Objective: Abnormal uterine bleeding (AUB) is defined as any bleeding from the uterus that is deviated from normal in terms of regularity, duration, frequency, and amount of blood loss. It interferes with the woman’s physical, emotional, social, and material quality of life. The prevalence of AUB ranges between 11% and 13% rising to 24% in perimenopausal women. The aim of this study is to analyze the demographic profile and risk factors of AUB in perimenopausal women, to classify the causes of AUB based on PALM-COEIN classification, and to correlate the clinical and sonological findings with post-operative histopathology findings.
Methods: A cross-sectional study was conducted in the Department of Obstetrics and Gynecology at GIMSR hospital, Visakhapatnam, for 1 year from September 2022 to September 2023. A total of 151 perimenopausal women with complaints of AUB in the age group of 41–50 years who underwent hysterectomy were included in the study.
Results: The most common clinical presentation was heavy menstrual bleeding (HMB) seen in 96 cases (63.5%). Clinically, the PALM component accounted for 61% of cases and the COEIN component accounted for 39% of cases. Ultrasonographically, the PALM component was detected in 76.8% of cases. We calculated the sensitivity, specificity, positive predictive value, and negative predictive value of ultrasound for detection of PALM lesions.
Conclusion: Leiomyoma was the most common cause clinically, sonologically, and pathologically. Correlation was good for leiomyoma. USG has good specificity for diagnosis of AUB-A and AUB-P but low sensitivity.
