Published: January 2023

Handball performance is a team-sport characterized by high intensity efforts interspersed with recovery periods. Due to high demands of handball performance, the use of ergogenic aids is a common strategy of handball players with the aim of enhancing handball performance, to allow more effective training, and to increase the rate of recovery. Although the use of ergogenic aids is generalized in the whole spectrum of competitive handball (e.g., from recreational to professional players), only a few ergogenic aids have been investigated to test their effectiveness to increase handball performance. In addition, no previous study has summarized the scientific literature on this topic to determine the ergogenic aids with good level of evidence regarding their effectiveness to increase handball physical performance. Thus, the aim of this narrative review was to describe the prevalence in the use of ergogenic aids in handball players and to analyse this information to identify which of these substances may increase physical performance in an intermittent sport such as competitive handball.

Published: January 2023

Antecedentes: Estudio que surge como consecuencia del proyecto SCIENCE-IES (UJA) dirigido por el Grupo de investigación HUM-653 y desarrollado por un grupo de estudiantes de 4o de la ESO de la SAFA de Úbeda. Se trata de acercarlos a la lucha libre, deporte olímpico no agresivo y poco conocido por los estudiantes, así como iniciarlos en la investigación alrededor de la violencia escolar (bullying).

Objetivo: Acercar al alumnado de Educación Secundaria a la metodología de investigación cualitativa, diseñando y aplicando un cuestionario para medir la violencia escolar y el entorno en el que se produce.

Material y Método: Estudio de carácter descriptivo y corte transversal, en el que participaron 185 alumnos de la SAFA de Úbeda con edades comprendidas entre 12 y 17 años (ESO y Bachillerato). El instrumento utilizado fue el cuestionario 4XBULLYING, elaborado ad-hoc por el grupo de estudiantes citado, con ayuda de los investigadores que firman este manuscrito. El cuestionario, de cuatro dimensiones (agresor presencial y virtual, víctima presencial y virtual), se difundió a través de Google Forms entre el alumnado de la SAFA.

Discusión y Conclusiones: En general se observa que son superiores los casos de bullying presencial que los de virtual, aunque parece frecuente que estas situaciones de acoso escolar empiecen con manifestaciones presenciales y posteriormente produzca el acoso en la red. Los agresores que actúan cara a cara optan por la invención de apodos sobre el físico de sus víctimas, mientras que los que lo hacen a través de las redes prefieren difundir información personal sin previo consentimiento del afectado. Por último, el alumnado participante destaca haber adquirido conocimientos sobre la lucha libre y la elaboración de un instrumento elemental de investigación como el cuestionario 4XBULLYING.

Evaluating Students’ Satisfaction with Their University and City: A Case in Turkey
Authors: YAZGAN Çağdaş Ümit
Published: January 2023

University satisfaction is not limited to academic processes, pedagogical interactions, or on-campus experiences. The city environment in

which students live outside the university can also affect students’ satisfaction levels. This research aims to define the city and university

satisfaction levels of students enrolled in a state university in Turkey, and to determine the relationship between students’ city and university

satisfaction levels. The research was designed with a descriptive and relational design within the scope of quantitative research methods,

and the sample consists of 1071 university students. A significant difference was found between city and university satisfaction and gender,

education level, size of the family residence, and geographical region. The research concluded that city satisfaction is a significant variable

in explaining university satisfaction. As students’ city satisfaction increases, university satisfaction also increases. City satisfaction explains

33% of the total variance in university satisfaction. Services and facilities that will increase university students’ city satisfaction positively

affect university satisfaction. This result shows that the city and the university have complementary qualities. At the same time, the results

show that university satisfaction of students cannot be reduced to pedagogical and academic activities and on-campus experiences. In this

context, it is possible that the university satisfaction level of the young people who study in a city is high, where the level of city satisfaction

is high in terms of basic needs, social and cultural interactions, feeling of safety, entertainment opportunities, sports activities, adequate

transportation, and travel services.

Published: January 2023

Objective: The aim of this study was to investigate the efficacy of intraoperative indocyanine green videoangiography (ICG-VA) and intraoperative neuromonitoring (IONM) to prevent postoperative ischemic complications during microsurgical clipping of unruptured anterior choroidal artery (AChA) aneurysms.Methods: We retrospectively reviewed the clinical and radiological records of all patients who had undergone microsurgical clipping for unruptured AChA aneurysms at our institution between April 2001 and December 2019. We compared the postoperative complication rate of the group for which intraoperative ICG-VA and IONM were utilized (group B; n=324) with that of the group for which intraoperative ICG-VA and IONM were not utilized (group A; n=72).Results: There were no statistically significant differences in demographic data between the two groups. Statistically significant differences were observed in the rate of overall complications (p=0.014) and postoperative ischemic complications related to AChA territory (p=0.039). All the cases (n=4) in group B who had postoperative infarctions related to AChA territory showed false-negative results of intraoperative ICG-VA and IONM.Conclusions: Preserving the patency of the AChA is essential to minimize postoperative complications. Intraoperative monitoring tools including ICG-VA and IONM can greatly contribute to lowering complication rates. However, their pitfalls and false-negative results should always be considered.

Published: January 2023

Epifluorescence miniature microscopes (‘miniscopes’) are widely used for in vivo calcium imaging of neural population activity. Imaging data are typically collected during a behavioral task and stored for later offline analysis, but emerging techniques for online imaging can support novel closed-loop experiments in which neural population activity is decoded in real time to trigger neurostimulation or sensory feedback. To achieve short feedback latencies, online imaging systems must be optimally designed to maximize computational speed and efficiency while minimizing errors in population decoding. Here we introduce DeCalciOn, an open-source device for real-time imaging and population decoding of in vivo calcium signals that is hardware compatible with all miniscopes that use the UCLA Data Acquisition (DAQ) interface. DeCalciOn performs online motion stabilization, neural enhancement, calcium trace extraction, and decoding of up to 1024 traces per frame at latencies of <50 ms after fluorescence photons arrive at the miniscope image sensor. We show that DeCalciOn can accurately decode the position of rats (n = 12) running on a linear track from calcium fluorescence in the hippocampal CA1 layer, and can categorically classify behaviors performed by rats (n = 2) during an instrumental task from calcium fluorescence in orbitofrontal cortex. DeCalciOn achieves high decoding accuracy at short latencies using innovations such as field-programmable gate array hardware for real-time image processing and contour-free methods to efficiently extract calcium traces from sensor images. In summary, our system offers an affordable plug-and-play solution for real-time calcium imaging experiments in behaving animals.
Identifying and Mitigating Flaws of Deep Perceptual Similarity Metrics
Authors: Sjögren Oskar , Pihlgren Gustav Grund , Sandin Fredrik , Liwicki Marcus
Published: January 2023

Measuring the similarity of images is a fundamental problem to computer vision for which no universal solution exists. While simple metrics such as the pixel-wise L2-norm have been shown to have significant flaws, they remain popular. One group of recent state-of-the-art metrics that mitigates some of those flaws are Deep Perceptual Similarity (DPS) metrics, where the similarity is evaluated as the distance in the deep features of neural networks.However, DPS metrics themselves have been less thoroughly examined for their benefits and, especially, their flaws. This work investigates the most common DPS metric, where deep features are compared by spatial position, along with metrics comparing the averaged and sorted deep features. The metrics are analyzed in-depth to understand the strengths and weaknesses of the metrics by using images designed specifically to challenge them. This work contributes with new insights into the flaws of DPS, and further suggests improvements to the metrics. An implementation of this work is available online: https://github.com/guspih/deep_perceptual_similarity_analysis/

Finding and amending contradictions in a financial report is crucial for the publishing company and its financial auditors. To automate this process, we introduce a novel approach that incorporates informed pre-training into its transformer-based architecture to infuse this model with additional Part-Of-Speech knowledge. Furthermore, we fine-tune the model on the public Stanford Natural Language Inference Corpus and our proprietary financial contradiction dataset. It achieves an exceptional contradiction detection F1 score of 89.55% on our real-world financial contradiction dataset, beating our several baselines by a considerable margin. During the model selection process we also test various financial-document-specific transformer models and find that they underperform the more general embedding approaches.
Questionable Practices in Methodological Deep Learning Research
Authors: Trosten Daniel J.
Published: January 2023

Evaluation of new methodology in deep learning (DL) research is typically done by reporting point estimates of a few performance metrics, calculated from a single training run. This paper argues that this frequently used evaluation protocol in DL is fundamentally flawed -- presenting 8 questionable practices that are widely adopted in the evaluation of new DL methods. The questionable practices are derived from violations of statistical principles of the scientific method, and from Hansson's definition of pseudoscience. A survey of recent publications from a top-tier DL conference indicates the widespread adoption of these practices in state-of-the-art DL research. Lastly, arguments in favor of the questionable practices, possible reasons for their adoption, and measures that have been taken to remove them, are discussed.
Signal and Visual Approaches for Parkinson's Disease Detection from Spiral Drawings
Authors: Gil-Martín Manuel , Luna-Jiménez Cristina , Fernández-Martínez Fernando , San-Segundo Rubén
Published: January 2023

The development of medical decision-support technologies that provide accurate biomarkers to physicians is an important research area. For example, in the case of Parkinson's Disease (PD), the current supervisions of patients become intrusive, occasional, and subjective. However, new technologies such as wearable devices, signal processing, computer vision, and deep learning could offer a non-intrusive, continuous, and objective solution to help physicians with patient monitoring. The Parkinson's Disease Spiral Drawings public dataset was selected to face PD detection in this work by comparing four representation methods of the X, Y, and the pressure time series: signal, visual, hand-crafted, and fusion. The signal approach uses the Fast Fourier Transform of recording windows and a Convolutional Neural Network for modeling; the visual strategy employs visual transformer features from gray-scale images; the hand-crafted technique utilizes statistics calculated from temporal signals, and the fusion combines the information from the previous approaches. In these procedures, a Random Forest classifier was used for PD detection using the attributes extracted from each type of representation. The best results showed an F1 score of 93.33% and 93.06% at the user level using a signal approach with the three signals for the Static Spiral Task and an image-based proposal with X and Y coordinates for the Dynamic Spiral Task, respectively.

Published: January 2023

Deep learning is proven to help with common medical image processing procedures, namely segmentation. Labeling data is a core requirement for training a deep learning model; this is time-consuming and expert annotators are in short supply. Strategies that lower data annotation requirements are highly desirable. In this study, we adapt cross-pseudo supervision (CPS) for 3D medical segmentation, a state-of-art semi-supervised deep-learning method where labeled and unlabeled data are used in conjunction to further improve the resulting model. Using the 2021 BraTS dataset, a fully labeled publicly available brain tumor dataset, we train CPS-based networks using a varying number of labeled and unlabeled samples and compare the resulting models against the fully-supervised baseline. The results show that CPS improves performance scores across all combinations of dataset sizes, with an increase in the Dice similarity coefficient (DSC) of 2.6-4.2% and a decrease in the 95th percentile Hausdorff distance (95% HD) of 24-27%.
Semi- and weak-supervised learning for Norwegian tree species detection

Published: January 2023

Tree species mapping of Norwegian production forests is a time-consuming process as forest associations largely rely on manual interpretation of earth observation data. Deep learning based image segmentation techniques have the potential to improve automated tree species classification, but a major challenge is the limited quality and availability of training data. Semi-supervised techniques could alleviate the need for training label and weak supervision enables handling coarse-grained and noisy labels. In this study, we evaluated the added value of semi-supervised deep learning methods in a weakly supervised setting. Specifically, consistency training and pseudo-labeling are applied for tree species classification from aerial ortho imagery in Norway. The techniques are generic and relevant for the wider earth observation domain, especially for other land cover segmentation tasks. The results show that consistency training gives a significant performance increase. Pseudo-labeling on the other hand does not, potentially this is due to varying convergence speeds for different classes causing confirmation bias or a partial violation of the cluster assumption.

Published: January 2023

Background

A multitude of Cry toxins (secreted by Bacillus thuringiensis or Bt) has been deployed globally either via transgenic mean or bio-pesticidal formulations in order to manage insect pests. However, Bt resistance development in insects is emerging as a major concern. To avoid this problem, multiple gene pyramiding or protein-engineered chimeric toxin-based strategy has been analyzed.

Methods

In the present study, one such chimeric toxin Cry1AcF (contain the swapped domains of Cry1Ac and Cry1F) was used to investigate its in vivo pathogenesis process in lepidopteran pests Spodoptera frugiperda and S. litura. A number of biochemical and molecular analysis were performed.

Results

Oral ingestion of Cry1AcF caused greater toxicity in S. frugiperda than S. litura with larvae displaying increased hemolymph melanization. Histopathology of the midgut transverse sections exhibited Cry1AcF-induced extensive gut damage in both the test insects followed by cytotoxicity in terms of reduced hemocyte numbers and viability. Elevated hemolymph phenoloxidase activity indicated the immune-stimulatory nature of Cry1AcF. In order to analyze the role of gut receptor proteins in Cry1AcF intoxication in test insects, we performed RNAi-mediated silencing using bacterially-expressed dsRNAs of individual receptor-encoding genes including CAD, ABCC2, ALP1 and APN. Target-specific induced downregulation of receptor mRNAs differentially altered the insect susceptibility to Cry1AcF toxin in our study. The susceptibility of ALP1 and APN dsRNA pre-treated S. frugiperda was considerably decreased when treated with Cry1AcF in LD50 and LD90 doses, whereas susceptibility of CAD and ABCC2 dsRNA pre-treated S. litura was significantly reduced when ingested with Cry1AcF in different doses. CAD/ABCC2-silenced S. frugiperda and ALP1/APN-silenced S. litura were vulnerable to Cry1AcF alike of control larvae. In conclusion, our results indicate ALP1/APN and CAD/ABCC2 as the functional receptor for Cry1AcF toxicity in S. frugiperda and S. litura, respectively.

Published: January 2023

The majority of global sectors were affected by the pandemic caused by a Coronavirus outbreak. This includes the academic world, which consists of millions of enrolled students and active teachers who previously had regular classes in their institutions but were forced to stay home due to the pandemic. To continue the educational process, most countries implemented online classes. Both teaching and learning take place in this mode using electronic devices and different online platforms relatively new to the teaching-learning community. The study used a quantitative method where the researcher surveyed the IBEd Faculty at St. Mary’s College of Baliuag to determine the frequency of educational technology tools such as Google Workspace for Education. A survey was conducted to evaluate the frequency of utilization and problems encountered by the Faculty in utilizing the Google Workspace Educational Tools. Results showed that the faculty were unfamiliar with some of the tools in Google Workspace and rarely used them in their classroom discussion. Teachers' responses revealed that they still need time to explore more of the different tools in Google Workspace and attend different pieces of training that will teach them how to use the tools. The results of the survey will provide valuable information in the design of professional training programs.

Authors: Wang Hao , Wang Xinyuanrui , Wu Junfei
Published: January 2023

The separation and recovery of lignin in black liquor is a hot topic in current research. Ceramic membrane technology has become the main method of lignin separation in black liquor due to its advantages of green environmental protection, high efficiency and high recovery rate. However, in the separation process, the problem of ceramic membrane fouling has always existed and has become the key to hinder its continuous separation. Aiming at the problem that the existing filtration methods can not meet the continuous separation of lignin in black liquor, this paper proposes to apply the blade dynamic cross-flow filtration device to the separation process of lignin in black liquor, and the influence of blade rotation speed on the separation performance is studied experimentally. The results showed that increasing the rotating speed of the blade could effectively reduce the accumulation of filter cake on the membrane surface and achieve the purpose of improving the filtration flux.

Authors: Koppad Anand , Chintamani Geeta C , Krupahree G , Shetty Sushma
Published: January 2023

Introduction: Chronic Obstructive Pulmonary Disease (COPD) is associated with right ventricular overloading and pulmonary hypertension. In COPD patients co-morbidities determine the outcome and quality of life. Cardiac Troponins (cTn) are suspected to be elevated in right ventricular failure. Aim: To find the incidence of cardiac Troponin-I levels and association of elevated cTnI levels with clinical outcome in acute exacerbation of COPD. Materials and Methods: The cross-sectional study comprised of 102 patients with acute exacerbation of COPD. These patients were admitted in medical wards and Intensive Care Unit (ICU) in the Department of General Medicine, Karnataka Institute of Medical Sciences Hospital, Hubli, Karnataka, India, from 2018-2020. Investigations included complete blood count, renal function tests, serum electrolytes, liver function tests, Electrocardiography (ECG), ECHO and chest X-ray. Association of cardiac troponin I and acute exacerbation of COPD was evaluated. The cTnI level ≥0.01ng/mL was considered positive. Results: The serum cTnI was found to be positive in 43 (42.2%) patients with acute exacerbation of COPD. The patients with cTnI levels ≥0.01 ng/mL had significantly higher need for Non Invasive Ventilation (NIV) 32 (74.4%), invasive ventilation support 5 (11.6%), prolonged duration of hospital stay 33 (76.7%), and higher mortality 15 (34.9%) rate as compared to patients having cTnI <0.01 ng/mL. Conclusion: The cTnI is elevated in a significant subset of patients with acute exacerbation of COPD. cTnI elevation was associated with higher need for NIV and invasive ventilator support. Levels of cTnI ≥0.01 ng/mL may be considered as a biomarker to predict morbidity and mortality in acute exacerbation of COPD patients.

Authors: Jani Sagar , Khare Pushkar , Kumar Sanjay , Khatri Bhavya
Published: January 2023

Introduction: Chronic Otitis Media (COM) refers to a chronic infection of mucosa lining the middle ear cleft and is the leading cause of conductive hearing loss in adults. The erosion or disruption of ossicular chain is determined while during the surgery. Complete disruption of ossicular chain can lead up to 60 dB hearing loss. Preoperative High-Resolution Computed Tomography (HRCT) scan of temporal bone can give a clue of ossicular integrity. Aim: To determine the association of preoperative audiological and radiological findings with the peroperative findings in cases of chronic otitis media. Material and Methods: This prospective clinical study was conducted in the Department of Otorhinolaryngology at Subharti Medical College and associated Chhatrapati Shivaji Subharti Hospital, Meerut, Uttar Pradesh, India, from October 2019 to August 2021. Seventy five patients of unilateral uncomplicated chronic otitis media (mucosal or squamosal), with conductive hearing loss, aged between 10 to 50 years were included in the study. Audiological assessment was done in form of pure tone audiometry using Alps 2100 instrument to measure hearing loss in decibels (dB). Radiological assessment was done using bilateral X-ray mastoid Schuller’s view, and HRCT temporal bone. Association of audiological and radiological findings was determined with intraoperative findings using Statistical Package for Social Sciences (SPSS) version 24.0. Results: The mean age of the study population was found to be 26.34±9.14 years. Females 42 (56%) were found to be affected more than males 33 (44%). Significant association was found between severity of hearing loss and necrosed ossicles seen peroperatively as p-value <0.05 in mucosal type of CSOM. Chances of peroperative ossicular necrosis (mucosal) were more in sclerosed (76.47%) and diploic (84.61%) mastoid as compared to pneumatized mastoid (7.69%) with statistically significant difference as p-value<0.01. Maximum accuracy of reporting for HRCT was found for the involvement of part of Incus. Conclusion: There was a significant association of audiological findings and number of ossicles necrosed peroperatively. hence, it can be concluded that greater the degree of hearing loss, more the chances of ossicular necrosis peroperatively.

According to the World Health Organisation (WHO), in the year 2018, more than 140,000 deaths occurred globally due to measles and its complications; most common in children <5 years of age. Aim: To evaluate the clinical profile of measles and its complications leading to death in children for better immunisation coverage and prevention of the disease. Materials and Methods: This was a prospective, observational study carried out in the Department of Paediatrics, New Civil Hospital (tertiary care hospital), Surat, Gujarat, India. Patient data was collected from January 2021 to December 2021 and data was analysed from January 2022 to June 2022. Study was done on all children with history of fever with rash and laboratory confirmed positive patients for measles Immunoglobulin M (IgM) antibody titer. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) software version 27.0. Results: During the study period only, 42 children with fever and rash had laboratory confirmed measles IgM positive antibody titre. Out of total, 42.86% of the study participants belonged to 1-4 years age group and 50% were unvaccinated. Males were more affected than female. Majority (81%) of cases occurred during late winter and spring seasons and most (78.57%) of the patients belonged to urban slum areas. Most common presenting complaint observed was maculopapular rash in all the children. Majority (95.24%) of the children were in eruptive stage of the disease. A total of 31 patients out of 42 developed complications with pneumonia as most common 38.71% children. All the patients recovered completely and were discharged from the hospital. Conclusion: There was decreasing trend of measles in young children. It can be due to recent immunisation campaigns and better coverage. Half of the patients in study were unvaccinated which indicates, there’s still work left to be done to immunisation scheme for better coverage.

The supply chain begins with acquiring fundamental raw materials and ends with delivering the finished product to the consumer. The growing interest in Agricultural Supply Chain Management (ASCM) can be attributed to two main factors: agricultural industrialization and the uncertainty brought on by differences in product quality and safety. The study objective was to identify different marketing channels of banana in Vadodara city, to estimate the price spread of banana and to identify problems faced by producers and intermediaries. Primary data were collected from 40 farmers, 15 wholesalers and 25 retailers to accomplish these objectives. Secondary data were collected from different private and government publications, review papers, literature, and journals. For the study descriptive type of research design was used. In the research sampling method was non-probability sampling method and sampling technique was convenience sampling technique were used. Channel-IV was the most effective way to reach consumers because it has the shortest route. Channel-I was less effective than the others because its marketing cost was the highest. The study reveals that the existing supply chain has a serious problem of lower prices faced by farmers. A significant problem for wholesalers is the lack of a ripening chamber. The major problem for retailers is that they suffer from higher post-harvest losses due to the lack of storage facilities, forcing them to sell products quickly to maximize profits and minimize losses. After doing certain changes like developing a ripening facility in marketing channel IV company may adopt this channel because its channel has the highest marketing efficiency and more share of producer in consumer rupee. To overcome these problems, there is a need to develop infrastructures, cold storage facilities, set up ripening chambers, processing facilities and use refrigerated vehicles for long-distance transportation, etc.

Published: January 2023

The Dagum distribution is a great tool for survival analysis as well as representing the distribution of actuarial, meteorological, and income data. Additionally, it is frequently thought to be the best option when compared to the other three parameter distributions. The inverse Burr distribution is a generalised Beta distribution that is produced from generalised beta-II by taking shape parameter one into consideration. The many characteristics and several techniques for estimating the unknown parameters of parameter Dagum distribution are covered in this article. Although we are able to estimate the parameter of the Dagum distribution using Bayesian methods with both informative and noninformative priors, the methods used to produce the estimators are different. Risk functions are used to compare these estimators.

Agricultural advisory services inform urban consumers about milk safety and quality information through diverse media channels. Communication about milk is vital in educating consumers to make informed, healthy food choices. However, knowledge gaps exist on whether the dominant message theme by media targets educating consumers. This study sought to fill these knowledge gap. Thematic content analysis of newspaper articles was used (n=215) and researcher-administered questionnaires (n=131) was used in Nairobi city. The respondents involved in the study were 131.The frequencies of text data were determined, and the dominant message themes were identified using Chi-square test statistics. The respondents rated media sources for educative value, on a Likert scale (1 to 5). Results revealed that the dominant print media message themes were innovations for enhancing good quality milk (36.7%), causes of poor-quality milk (43.7%), benefits of quality milk (10.7%), and risks of poor-quality milk (8.8%). The relative consumer trust for information disseminated by agricultural advisors through different media channels was in the order of television (20.2%), radio (19.5%), product advertisement (16.7%), social media (13.5%), newspapers (12.4%), public extension (7.5%), research by university (6.8%), and lastly extension magazines (3.4%). Consumers placed greater trust on messages disseminated through television, which in their perception was of greater educative value to them.

Published: January 2023

The overall estimated burden of Inflammatory bowel disease in India in 2010 came out to be 1.4 million. Aim of our study was to focus on histomorphological findings of rare Crohn’s disease  and  discuss the role of serum Antisaccharomyces cerevisiae (ASCA) antibody level and short standard anti-tubercular therapy for 15 days. We reported 4 cases on histopathology at our institute between june 2021 to march 2022. Both intestinal tuberculosis and Crohn’s disease are chronic granulomatous lesion , but the absence of well defined microgranuloma and caseous necrosis  on histopathology are clinching point against Intestinal tuberculosis, favouring Crohn’s disease. Microbiological findings and serum ASCA antibody level were of no use in differentiating Crohn’s from tuberculosis. Early diagnosis of both entities are important as management differs from one another.

Published: January 2023

AZ91D, a die‐casted alloy, offers several benefits (better saltwater corrosion resistance, suitable castability, and good atmospheric stability) over other grades of magnesium alloy. However, it cannot overcome the challenging requirements of advanced applications in its current form. Extensive research in coating technologies is crucial in enhancing the performance of AZ91D alloy in highly corrosive environments (coastal and marine, industrial, farm, etc.). The high corrosion resistance of AZ91D for various applications is achievable through the deposition of different materials. Developments in coating materials and techniques, with their influence on the corrosion protection behavior of AZ91D alloy, over the last decade (2012–2022), are focused on in this study. It is observed that composite, biodegradable, and self‐healing coatings are gaining popularity. The transition in the coating technology, from conventional to self‐healing coating materials and from conventional to environment‐friendly coating techniques, is a vital part of this discussion. This review further explores how different additives, pre‐treatments, post‐treatments, and corrosion inhibitors affect the corrosion performance of coatings. This study helps select the optimum coating material for AZ91D magnesium alloy to fulfil a specific application requirement and guides toward technological developments in this segment.
