Background
Antimicrobial resistance (AMR) is a major global public health crisis and around the last decade, newspapers were one of the main sources of public dissemination of information for so. This study highlights how Bangladeshi mainstream newspapers represented AMR-related news and how they created the narrative of AMR in Bangladesh.

Methods
We conducted both quantitative and qualitative content analysis on 275 AMR-related news articles published in the twelve highest circulated dailies (January 2010 to September 2021). We divided the articles into report, opinion, and editorials and analyzed how their contents built the narrative of AMR in Bangladesh.

Results
Bangladeshi newspapers reported misuse of antibiotics by the consumers the most (32.2%), followed by selling without prescriptions (29%), and over-prescription by the health providers (26.1%). There were hardly any news reports describing the impact of pharmaceutical companies in prescribing and selling antibiotics. Around 45% of the news articles were event-oriented. Moreover, they suggested inadequate recommendations to battle AMR.

Conclusion
Valid, consistent, and reliable AMR news coverage can play a crucial role in creating mass awareness, making providers accountable, and supporting national action plan in mitigating AMR threat. The Bangladeshi journalists interested in reporting AMR-issues should focus on disseminating more Bangla articles with scientific information, and reporting causes and recommendations responsibly.
Development of Motion Graphic Video on Class XI Colloid Materials in Increasing Students' Interest in Learning
Authors: Abd.latif  
Published: May 2024

Colloidal material is an abstract material that causes students to have difficulty learning it. The difficulty of colloidal material causes students' interest in learning to decrease. This research aims to produce motion graphic video-based learning media on colloid system material to increase students' interest in learning. This research uses research and development (R&D) methods with a 4-D model, which consists of four stages, namely define, design, develop, and disseminate. However, this development is limited to the development stage only. The product was reviewed by the supervisor and four peer reviewers and then validated by one material expert and one chemist. The quality of the media was assessed by four reviewers (high school/MA chemistry teachers) and responded to by 10 high school/MA students. The Linkert scale is used as a product quality assessment questionnaire sheet and the Guttman scale is used as a student response questionnaire sheet. The product produced in this research is a chemistry learning video on colloid system material. The assessment results from material experts obtained an ideal percentage of 80% and were included in the good category. The results of the media expert assessment obtained an ideal percentage of 85% and were included in the very good category. The assessment results from the reviewers (four SMA/MA chemistry teachers) obtained an ideal percentage of 91.36% and were included in the very good category. The results of the responses of ten high school students obtained an ideal percentage of 95%. Based on the assessment results, it can be concluded that the motion graphic video developed can be used as an alternative learning media for colloid system material to increase interest in learning
Accelerating String-Key Learned Index Structures via Memoization-Based Incremental Training

Learned indexes use machine learning models to learn the mappings between keys and their corresponding positions in key-value indexes. These indexes use the mapping information as training data. Learned indexes require frequent retrainings of their models to incorporate the changes introduced by update queries. To efficiently retrain the models, existing learned index systems often harness a linear algebraic QR factorization technique that performs matrix decomposition. This factorization approach processes all key-position pairs during each retraining, resulting in compute operations that grow linearly with the total number of keys and their lengths. Consequently, the retrainings create a severe performance bottleneck, especially for variable-length string keys, while the retrainings are crucial for maintaining high prediction accuracy and in turn, ensuring low query service latency.
To address this performance problem, we develop an algorithm-hardware co-designed string-key learned index system, dubbed SIA. In designing SIA, we leverage a unique algorithmic property of the matrix decomposition-based training method. Exploiting the property, we develop a memoization-based incremental training scheme, which only requires computation over updated keys, while decomposition results of non-updated keys from previous computations can be reused. We further enhance SIA to offload a portion of this training process to an FPGA accelerator to not only relieve CPU resources for serving index queries (i.e., inference), but also accelerate the training itself. Our evaluation shows that compared to ALEX, LIPP, and SIndex, a state-of-the-art learned index systems, SIA-accelerated learned indexes offer 2.6× and 3.4× higher throughput on the two real-world benchmark suites, YCSB and Twitter cache trace, respectively.
New database for the estimation of dynamic coefficient of friction of snow
Authors: Aggarwal Rakesh K. , Das Ranjan , Gusain Hemendra S. 
Published: May 2024

Abstract
Knowledge of the Coulomb dynamic coefficient of friction of snow is a vital input parameter for the estimation of run-out distance, velocity, forces, and lateral spread of the snow avalanches in the hilly regions. This parameter is defined as the ratio of the wall shear force to the normal force components of an avalanche. Avalanches are one of the most devastating natural hazards. So, the proper understanding of avalanche flow parameters is vital for the people and the infrastructure in the mountainous regions of the world. Notwithstanding the utmost significance of the Coulomb friction parameter, a few measurements are available for this parameter. In the present work, based on 32 measurements carried out from 2017 to 2020, a new database for the shear force and normal force components of the avalanches and derived values of the dynamic coefficient of friction between the chute steel surface and the flowing snow are presented. The measurements were carried out using a three-component piezoelectric load cells-based dynamometer which in turn was installed on the 12° slope of a 61-m long snow chute, located in the Pir Panjal Himalayan range of India. Based on all the measurements, the average value of the dynamic coefficient of friction for snow-steel surface is estimated to be 0.113 with a standard deviation of 0.032. The results have been exhibited to be in accordance with the published literature. It is expected that the present database will be highly significant for the validation and improvement of avalanche dynamics models especially for high-density wet snow conditions. Further, shear force and normal force components data may be useful for the designing of snow sheds in mountainous regions.
Experimental study on the influence of clay content on the shear strength of silty soil and mechanism analysis

Published: May 2024

Abstract
Shear strengths of silty soil were determined for shallow destruction of the soil sites frequently occurring in the Central Plains area. Specimens were prepared with five different clay contents (5, 10, 15, 20, and 25%) prior to compaction at dry densities of 1.60, 1.70, and 1.80 g/cm3. Soil specimens were saturated and then the consolidated undrained shear test was conducted with eight confined pressures ranging from 1 to 400 kPa. Results indicate that the shear strength increases significantly as the clay content increases from 5 to 25%, and the cohesion c shows bilinear function with the inflection point at the clay content of 10%. The difference of cohesion in the high and low stress sections decreases gradually to almost the same value until 25% of the clay content, while the internal friction angle φ decreases with the increase in clay content. Within the range of dry density and clay content tested, the shear strength of silty soil in the low stress range obtained is higher than the measured value. Therefore, for the shallow damage of soil site, the shear strength parameters should consider the low stress test conditions. The bilinear growth of cohesion c with clay content can be attributed to the changes from “sand-like soil” to “clay-like soil” with the skeleton of soil specimen transitioning from sand particles to “clay grid” when the clay content exceeds approximately 10% combined with the results of scanning electron microscopy.

Abstract
Efforts to increase the number of filters are driven by the demand for miniaturized spectrometers and multispectral imaging. However, processes that rely on sequential fabrication of each filter are cost ineffective. Herein, we introduce an approach to produce at least 16 distinct filters based on a single low-resolution lithographic step with minimum feature size of 0.6 μm. Distinct from grayscale lithography, we employ standard binary lithography but achieve height variations in polymeric resist through a post-development reflow process. The resulting transparent polymeric films were incorporated in Fabry–Perot cavity structures with cavity thickness ranging from 90 to 230 nm to produce transmittance across the visible spectrum. This binary lithography and reflow (BLR) process demonstrates control of the dielectric layer thickness down to ∼15 nm. This new process provides a cost-effective alternative to traditional techniques in fabricating microscopic transmission filters, and other applications where precise thickness variation across the substrate is required.

Abstract

Background
Recent reports highlight the effectiveness of mud therapy in various health conditions. A previous study showed that applying a mud pack (MP) to the abdomen and eyes effectively lowered blood pressure (BP) in healthy individuals. However, there have been no studies investigating the immediate effects of MP on the abdomen and eyes in patients with hypertension. This pilot study aims to determine the immediate impact of MP on cardiovascular parameters in patients with hypertension.

Material and methods
This preliminary study involved 30 adults aged 50 ± 11 years who had hypertension. After obtaining detailed informed written consent from all the patients, a single session of MP application on the abdomen and eyes was administered for a duration of 20 min. BP measurements were taken both before and after the 20-min intervention.

Results
Immediately following the application of MP on the abdomen and eyes, a statistically significant (p < 0.05) reduction was observed in BP variables such as systolic BP, diastolic BP, mean arterial BP, pulse pressure, rate pressure product, and double product among the patients with hypertension.

Conclusion
The outcome of this pilot study showed that MP could be effective in reducing BP among the patients with hypertension. This suggests its potential as a safe and economically feasible adjunctive therapy for hypertension management. However, further studies with large samples are needed to find the duration of the effectiveness.
Salt Production in Central Italy and Social Network Analysis Centrality Measures: An Exploratory Approach
Authors: Fulminante Francesca , Alessandri Luca 
Published: May 2024

Abstract
In this work, we study salt-production settlement in central Italy with an exploratory application of centrality indexes, common in social network analysis: betweenness centrality, closeness centrality, and degree centrality. These methods are not new, but they have never been applied to this type of site and the results are innovative and illuminating. In fact, the closeness and degree centrality do not yield particularly interesting results. However, the betweenness centrality, which indicates the most commonly used routes in a given region, provide powerful insights. By indicating shifting most common routes through time, from the terrestrial and sea route along the coast in the Bronze and Iron Age, to the use of the Tiber River and Tiber valley as route, in the Orientalizing and Archaic Period, they allow us to advance hypotheses about the shift between two different productions. The briquetage salt production technique was used in the Bronze and Iron Age on the costal sites, which was also the most common route used in the region. While the proper marine production at the mouth of the Tiber, both on the Etruscan and Latin side, might develop during the Orientalizing and Archaic Age, together with an intensified use of the Via Salaria, running from the coast to the mountains of Latium, along the Tiber River. It would be interesting to confirm these hypotheses with further analyses and also targeted excavations.
Investigation on flow characteristics and its effect on heat transfer enhancement in a wedge channel with combination of circular, oblong, teardrop, and pencil pin fins

Published: May 2024

Abstract
Gas turbine engines are used extensively in a variety of industries, including power generation, aviation, and marine propulsion. One of the most difficult issues in developing gas turbine engines is dealing with the high temperatures. Internal cooling is a typical strategy for keeping important components, such as turbine blades, at a safe working temperature. Pin-fin cooling is a significant technology used in gas turbine blades to manage severe operating temperatures. This research paper investigates the impact of a new geometry combining two pin fins in cooling channels in gas turbine blades. The study involved testing seven different pin-fin arrays over a Reynolds number varying from 10,000 to 80,000 and a constant heat flux of 3280 W/m2 applied to all the surfaces. The findings indicate that the use of pencil pin fins leads to a notable enhancement in cooling efficiency owing to the existence of a low-pressure drop, 5.2 % compared to pencil and tear drop pin fins and by 1.6 % compared to pencil and oblong pin fins, and it is 1.7 % less than pencil and circular fins.

Published: May 2024

AbstractBackground and aimsIbogaine, an alkaloid extracted from the root of the Tabernanthe Iboga shrub, holds promise in treating addictive disorders. Individuals receiving ibogaine treatment report decreased withdrawal symptoms, cravings, and addiction severity. These changes are often attributed to ibogaine's psychedelic properties: subjectively meaningful, dream-like experiences. Research demonstrates that ibogaine experiences impact multiple social-ecological dimensions and influence addiction and recovery trajectories. No studies have explored the multidimensional experiences of individuals seeking ibogaine treatment for addictions. The current study examines acute and enduring ibogaine experiences at individual, interpersonal, and behavioral health systems levels.MethodsFifteen individuals (5 female, 10 male) who received ibogaine treatment at a medical clinic in Ensenada, Mexico completed semi-structured interviews asking about individual, interpersonal, and behavioral health system experiences post-ibogaine within 12 months of ibogaine treatment (Mdn = 169 days). Transcripts were coded and analyzed using a Consensual Qualitative Research approach.ResultsMany participants reported seeking ibogaine treatment after exhausting other addiction services. Outcomes reported following treatment included alleviated cravings and withdrawal symptoms. Participants indicated that ibogaine experiences prompted insight into their addictions and contributed to their recovery. Self-support and disclosing ibogaine experiences to professional and non-professional supporters were important to participants' recovery post-ibogaine.ConclusionsIntersecting experiences across social-ecological levels had an enduring impact on participants' addiction recovery after ibogaine treatment. Despite negative experiences with behavioral health systems prior to receiving ibogaine treatment, most participants sought the support of mental health professionals post-ibogaine. Findings are informative for mental health professionals and clients interested in ibogaine treatment.
Women in Masculinized Occupations, Men in Feminized Occupations: Experiences of Gender Occupational Minorities and Their Roles within the Occupational Group
Authors: Czeranowska Olga 
Published: May 2024

Horizontal gender segregation divides the labor market into ‘feminine’ and ‘masculine’ occupations. However, some individuals choose occupational paths which are not consistent with the expectations for their gender, thereby becoming a minority in their occupational group. We propose the joint term ‘gender occupational minorities’ to describe their situation. We aim to supplement previous research with a combined analysis of the two gender groups, enabling a more general perspective on the meaning of gender in the labor market as well as a comparison of how similar mechanisms work in opposite gender contexts. Based on Pierre Bourdieu’s practical principles of gender occupational segregation, women working in IT/new technologies and men working in childcare/education were chosen as the project’s target groups. In this paper, we focus on the experience of being a gender occupational minority on the Polish labor market as well as on the role of gender occupational minorities within the occupational group.

Les puits traditionnels à usage domestique constituent une source importante en eau pour une frange de la population du district d’Abidjan. Étudier la qualité de cette eau devient une nécessité. C’est pourquoi ce travail a été initié. Il a pour objectif d’évaluer l’impact des matériaux de protection des puits traditionnels à usage domestique sur la qualité des eaux. Pour mener à bien cette étude nous avons identifié, après enquête, cinq (5) puits traditionnels issus de la même zone géologique. Parmi ces puits choisis, quatre (4) possèdent des matériaux de protection tels que les pneus d’automobiles, les fûts métalliques, le plastique en PVC (polychlorure de vinyle) et les briques de ciment pour leur cuvelage. Quant au cinquième qui représente le puits témoin, il ne possède pas de matériaux de protection ou cuvelage. Les eaux de ces puits ont été soumises à des analyses physico-chimiques sur la base de la norme française et celles décrites par Rodier et al. Les résultats de cette étude montrent que le fer et la silice qui sont des constituants chimiques des pneus d’automobiles, des briques et plastique en PVC sont en concentrations très importantes dans les eaux dont les cuvelages sont confectionnés à partir de ces matériaux. Les différents éléments chimiques (silice et fer) se retrouvent dans ces eaux par les réactions de dissolution et d’oxydation.

Traditional wells for domestic use are an important source of water for part of the population of the Abidjan district. It is essential to study the quality of this water. That is why this study was initiated, with the aim of studying the impact of materials used to protect traditional domestic wells on water quality. To carry out this study, we identified five (5) traditional wells by means of a survey. Four (4) of these wells had protective materials such as car tyres, metal drums, PVC plastic and cement bricks in the casing. The fifth, the control well, has no protective materials. Their water was subjected to physico-chemical analysis. These analyses were carried out using French standard methods and those described by Rodier et al. Iron and silica, which are chemical constituents of car tyres and bricks, and PVC plastic exclusively in the case of silica, were found in very high concentrations in the water whose casings were made from these materials, compared with the control well. In fact, the control well is uncased and shares the same geological nature as the other cased wells. The various chemical elements (silica and iron) are found in this water through dissolution and oxidation reactions. The physico-chemical parameters of the wells with casings were compared with those of the control wells using the non-parametric Mann-Whitney test, and the well waters were divided into groups using Principal Component Analysis (PCA).
