Purpose. It consists in establishing the influence of continuous fibers and a sufficiently plastic matrix of heat-resistant alloy in the structure of a composite intended for work at elevated temperatures, and providing recommendations on the optimal type of structure to achieve optimal strength of this composite at temperatures of 20...1300 °С.
Research methods. Theoretical analysis of the possible destruction of products when using continuous fibers was carried out, as well as an analysis of composite samples based on a heat-resistant matrix reinforced with a wire made of tungsten-rhenium alloy. The research was conducted using the metallographic method. The strength of the composite was determined by carrying out tensile tests using the IMASH-20-75 device.
Results. The regularities of the influence of the structure on the strength of fibrous composites have been established, on their basis it is possible more thoroughly analyze the processes that occur both during the destruction of the composite and during its formation and, if necessary, to adjust them in such a way as to ensure the maximum possible strength of the material as a whole.
Scientific novelty. The regularity of the effect of the general structure of the composite and the matrix surrounding the fibers on the strength of the heat-resistant alloy – tungsten-rhenium fiber composite is established, which allows quantitative analysis of the influence of structural and technological factors of the forming process on the strength of the specified material.
Practical value. The work can be useful to designers when choosing the composition of the composite, focusing on the expected mechanism of destruction, as well as to technologists for more productive use of production equipment and reducing the consumption of materials for the production of products.

Published: March 2024

Purpose. The aim of the study is to establish the patterns and mechanisms of pitting of the 06ХН28МДТ alloy in model recycled waters with a pH of 4-8 and a chloride concentration of 350 up to 600 mg/l, which are most often used in industrial enterprises.
Research methods. A mathematical model based on regression trees to establish the relationship between the critical pitting temperatures (CPT) of the 06ХН28МДТ alloy and its chemical composition, structure components, and parameters of model recycled water (pH, chloride concentration) has been developed. Metallographic analysis, energy dispersion analysis, regression analysis.
Results. Based on the results of the analysis of the developed mathematical model, chemical composition, structural heterogeneity of the alloy, and known literature data, it was found that in model recycled waters with a pH of 4.5 up to 7.5, the CPT of the 06ХН28МДТ alloy has a constant value of about 48.3 °C, which does not depend on its chemical composition, structural components, and chloride concentration in the model recycled waters. In model recycled waters with a chloride concentration of 350 up to 600 mg/l, the alloy’s CPT increases, on mean, to 59 °C, with an increase in their pH from 7.5 up to 8, but it decreases to 39 °C, with its decrease from 5 to 4. It has been found that the pH of the media has a more significant effect on the CPT of the alloy than the concentration of chlorides in it. It was found that the pH of the media has a more significant effect on the CTE of the alloy than the concentration of chlorides in it.
Scientific novelty. Based on the established patterns between the critical pitting temperatures of the 06ХН28МДТ alloy and its chemical composition, structure components, and parameters of recycled water, the mechanisms of its pitting has been determined, in particular, in low acidic media with pH 4.5, its CPT is minimal, which is due to a decrease in the hydrogen ionisation overvoltage on the carbide phase (Cr, Mo, Ti, Si, Mn, C) in the vicinity of titanium nitrides, where pitting occurs, and in close to neutral model recycled waters, the alloy’s CPT is higher in a wide pH range, which is associated with the formation of an oxide film from a monolayer of Cr atoms on its surface due to its solid-phase diffusion under the influence of Mn, but in low alkaline model recycled waters, the alloy’s CPT is the highest, which is due to a decrease in the activity of chlorine ions and their adsorption on the imperfections of the alloy structure.
Practical value. The developed mathematical models are proposed to be applied to the selection of the most resistant melts to pitting in recirculating industrial waters of the alloy 06KhN28MDT melts and prediction of its pitting during the operation of heat exchangers.

Published: March 2024

The objective of the research was to investigate the utilization of oropharyngeal throat pack during maxillofacial surgeries at various institutions in Maharashtra.A randomized prospective survey was conducted using a total of 139 anonymous questionnaires to investigate the utilization, attitudes, experiences, and mindsets of anesthesiologists (n = 53) and surgeons (n = 86). The study solely relied on questionnaire-based observations and did not involve any clinical research.46.33% of individuals provided their responses. The utilization of Throat Pack (TP) is infrequent or non-existent among less than 33% of surgeons and slightly more than 33% of anaesthesiologists. Around 50% of the participating surgeons acknowledged being aware of 1 to 4 nonfatal adverse events. Notably, there exists a notable disparity in viewpoints concerning the removal of Throat Pack and the ultimate responsibility for its removal.Throat packs are commonly employed in maxillofacial surgeries. Moreover, it seems that despite recent advancements, there might still exist a divergence of viewpoints among the surgical and anaesthesiology teams concerning specific responsibilities.

Published: March 2024

O Compliance Fiscal está no cerne do funcionamento saudável das sociedades. O objetivo deste ensaio é analisar as fraudes e conformidade tributária no Brasil, objetivando identificar possíveis contribuições para estes temas. A relevância deste estudo está em aprofundar o debate sobre o desenvolvimento do conhecimento em conformidade tributária, o que muito provavelmente acarretará em um desenvolvimento dessa ciência. A metodologia de pesquisa é revisão de literatura para sabermos o estado da arte do tema e em um segundo momento uma análise crítica sobre a conformidade tributária no território brasileiro. O custo das fraudes é 3,77 vezes o valor das operações fraudulentas, fica evidente o que a sociedade brasileira está perdendo com as fraudes. Será que somente compliance, controles internos, auditoria, atos regulatórios serão suficientes para mitigar as fraudes no contexto brasileiro? Sabemos que essas medidas são fundamentais, mas não irá mitigar 100%.

Erratum to: Progress Note 2024: Curing HIV; Not in My Lifetime or Just Around the Corner? doi: 10.20411/pai.v8i2.665
In the original publication, the comments provided by Santiago Ávila-Ríos were mistakenly omitted. In this version, his comments are included in the “Comments by Leaders” section, and his name has been included in the list of authors. ---Once a death sentence, HIV is now considered a manageable chronic disease due to the development of antiretroviral therapy (ART) regimens with minimal toxicity and a high barrier for genetic resistance. While highly effective in arresting AIDS progression and rendering the virus untransmissible in people living with HIV (PLWH) with undetectable viremia (U=U) [1, 2]), ART alone is incapable of eradicating the “reservoir” of resting, latently infected CD4+ T cells from which virus recrudesces upon treatment cessation. As of 2022 estimates, there are 39 million PLWH, of whom 86% are aware of their status and 76% are receiving ART [3]. As of 2017, ART-treated PLWH exhibit near normalized life expectancies without adjustment for socioeconomic differences [4]. Furthermore, there is a global deceleration in the rate of new infections [3] driven by expanded access to pre-exposure prophylaxis (PrEP), HIV testing in vulnerable populations, and by ART treatment [5]. Therefore, despite outstanding issues pertaining to cost and access in developing countries, there is strong enthusiasm that aggressive testing, treatment, and effective viral suppression may be able to halt the ongoing HIV epidemic (ie, UNAIDS’ 95-95-95 targets) [6–8]; especially as evidenced by recent encouraging observations in Sydney [9].
Despite these promising efforts to limit further viral transmission, for PLWH, a “cure” remains elusive; whether it be to completely eradicate the viral reservoir (ie, cure) or to induce long-term viral remission in the absence of ART (ie, control; Figure 1). In a previous salon hosted by Pathogens and Immunity in 2016 [10], some researchers were optimistic that a cure was a feasible, scalable goal, albeit with no clear consensus on the best route. So, how are these cure strategies panning out? In this commentary, 8 years later, we will provide a brief overview on recent advances and failures towards identifying determinants of viral persistence and developing a scalable cure for HIV. Based on these observations, and as in the earlier salon, we have asked several prominent HIV cure researchers for their perspectives.

Ideal Timing of Reimplantation in Patients with Periprosthetic Knee Infection Undergoing 2-Stage Exchange
Authors: Ascione Tiziana , Balato Giovanni , Festa Enrico , Pandolfo Giuseppe , Siciliano Roberta , Pagliano Pasquale 
Published: March 2024

Background:
This study evaluated appropriate thresholds for serum biomarkers, synovial fluid white blood cell (SF-WBC) count, and synovial fluid neutrophil (polymorphonuclear leukocyte [PMN]) percentage to predict infection in a patient group who underwent definitive reimplantation after receiving a continuous course of antibiotic therapy for chronic knee periprosthetic joint infection (PJI). These thresholds were then used to generate a scoring system to predict recurrence (or persistence) of infection.

Methods:
The study included 153 patients with a median age of 73 years (range, 46 to 91 years) who underwent 2-stage revision for chronic knee PJI. Staphylococci were identified at baseline in 107 (70%) of the patients. After the 96-week follow-up period, 12% (19) of the 153 patients had recurrence of the PJI. A receiver operating characteristic (ROC) curve analysis was used to assess the predictive value of common serum biomarkers and SF aspiration before reimplantation, and the area under the curve (AUC) was evaluated. Variables that were significantly different between patients with and without infection recurrence were evaluated using a multivariable logistic regression model. A half-integer-point scoring system was created based on the final beta coefficients.

Results:
Regarding the prediction of recurrent infection, a D-dimer level of >1110 ng/mL yielded a sensitivity of 74%, specificity of 61%, and AUC of 0.69; an SF-WBC count of >934 cells/µL showed a sensitivity of 68%, specificity of 90%, and AUC of 0.79; and an SF-PMN percentage of >52% showed a sensitivity of 73%, specificity of 90%, and AUC of 0.82. The beta coefficients were approximated to 1.5 for the D-dimer level and to 2 for the SF-WBC count and SF-PMN percentage. A total score of >2 was used to classify patients with a high risk of infection recurrence. The ability to discriminate infection recurrence was demonstrated by an AUC of 0.90 (95% confidence interval: 0.82 to 0.99).

Conclusions:
Patients with a score of >2 on our proposed scoring system based on serum biomarkers, SF-WBC count, and SF-PMN percentage should not undergo reimplantation, as they are at a high risk for recurrent PJI. Patients with a score of ≤2 can undergo definitive reimplantation with the lowest risk of recurrence.

Level of Evidence:
Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Groundwater rivals aridity in determining global photosynthesis
Authors: Giardina Francesco , Seneviratne Sonia I. , Liu Jiangong , Stocker Benjamin D. , Gentine Pierre 
Published: March 2024

Abstract

Understanding the role of groundwater in regulating photosynthesis is key in land-climate interactions. However, the impact of groundwater on terrestrial ecosystem productivity remains poorly understood. Here, we use satellite observations of solar-induced fluorescence as a proxy for photosynthesis, together with estimates of water table depth (WTD) and aridity as quantified by the annual moisture index with reanalysis data, to investigate the relationships between groundwater and photosynthesis. Using explainable machine learning (Shapley additive explanations or SHAP), we demonstrate that groundwater plays a crucial role in determining the spatial patterns of global photosynthesis, with varying importance across different ecosystem types, and that this effect is comparable to aridity. We show that in forests across the contiguous USA (CONUS), the relative importance of groundwater represents 89% of the effect attributed to the moisture index in modulating photosynthesis, and this impact is even more pronounced globally (105% relative importance). The relative importance of groundwater compared to the moisture index remains substantial in grasslands (37%), savannas and shrublands (25%), and croplands (15%) in CONUS. Global analysis confirms these trends for grasslands (41%) and croplands (15%) but indicates a 60% importance in savannas and shrublands. Our findings highlight the key global role of groundwater in driving ecosystem productivity.

Authors: Sinha Gaurav R. , Power Shannon R. , Kursuncu Ugur 
Published: March 2024

Abstract
Purpose
The purpose of this study was to explore underlying patterns in the users’ discussions in an online community on the darker effects of COVID-19. Understanding these patterns is critical as they can provide new information in tailoring support to individuals facing specific post-pandemic issues.
Methods
A mixed-method approach was used to identify patterns in large volumes of publicly available responses (n = 23,957 posts; ~1,061,825 words) from an online community. Qualitatively, 1,000 random responses were manually coded by two coders and vetted by an investigator. As it was difficult to manually code such a big dataset, a quantitative approach building a topic model was employed with a language model.
Results
Qualitative analyses revealed 20 themes, including mental health (13%), impacts of direct and indirect deaths on socio-economically vulnerable groups (e.g. children and elderly, 10.4%), increasing sociopolitical divide and vaccination debate (6.8%), and work-related issues (e.g. burnout and layoffs, 6%). Topic analyses resulted in similar categories (n = 30), including physical health, loss experiences during COVID-19 & suicide; sociopolitical impact & adaptations in pandemic lifestyle; mental health & vaccination; pandemic restrictions, youth & behavioral expectations; distrust for institutions & resource scarcity; staffing issues & personal crisis; disrupted careers; and childcare challenges & economic shifts.
Conclusion
As researchers are harnessing vast amounts of real-time human interaction data to study a variety of public health issues, our study provides insights into the specific challenges that people experienced when it became convenient to share concerns online amid an overloaded healthcare system during the pandemic.
Machining Induced Damages in the Drilling of CFRP under Dry and Cryogenic Environments
Authors: Mathiyazhagan Vijayathithan , Meena Anil 
Published: March 2024

Abstract

Carbon Fiber-Reinforced Polymers (CFRP) present machining challenges due to inherent properties such as inhomogeneity and anisotropy, which make them vulnerable to damage during drilling. This study investigates the machining-induced damage caused by drilling CFRP composite laminates under dry and cryogenic conditions, considering the impact of cutting speeds, feed rates, and tool coatings on thrust force, delamination, and surface roughness. Acoustic Emission (AE) measurements are also performed to investigate machining-induced damage at different stages of the machining process. The experimental results show that machining-induced damage is significantly reduced under cryogenic conditions compared to dry drilling. Under cryogenic conditions, the combination of high feed rates and cutting speeds resulted in a 13.2% reduction in average delamination factor, a 10.5% improvement in surface roughness, and a 43.4% decrease in acoustic emission RMS compared to dry drilling. A scanning electron microscope (SEM) and a 3D surface profilometer are also used to assess machining-induced damage to the hole wall surface under dry and cryogenic conditions.
