Crystals of Organic Acid-Bases Complexes Defy the pKa Rule Under Compression
Authors: Das Shovan , Pratik Saied , Datta Ayan
Published: May 2024

Crystals of organic acid-base adducts are major components in the active pharmaceutical ingredients (API). These 1:1 adducts either form a co-crystal with a hydrogen-bonded motif or a salt by transfer of proton from the acid to the base. As a rule of thumb if the difference in pKa between the protonated base and the acid (ΔpKa) is ≤ 1, a co-crystal is expected while ΔpKa > 3 leads to a salt. The preferred crystalline form for 1:1 adducts of pyridine, pyridazine, pyrazine and furan with formic acid are elucidated using genetic algorithm assisted first-principles crystal structure predictions (CSP). In agreement with the ΔpKa rule, all the adducts stabilize as H-bonded co-crystals under ambient pressure. However, under isotropic pressure formic acid transfers the protons to the three nitrogenous bases forming salts of pyridinium formate, pyridazinium formate and pyrazinium formate. External pressure is found to dictate the co-crystal – salt equilibrium. The critical pressure (Pc) required to induce co-crystal → salt conversion for formic acid… pyridine/pyridazine/pyrazine is 3 GPa, 5 GPa and 15 GPa respectively. Compression is shown to enhance the electrostatic interactions between the molecules leading to additional stabilization of the ionic configurations namely, N+-H…O- in salts vis-à-vis the neutral N-H…O motifs in the co-crystals. Violating the ΔpKa rule, Pc overcomes the free-energy required for the proton-transfer (ΔGPT) to stabilize the salts. The very high ΔGPT = 177.9 kcal/mol for the furan…formic acid adduct prevents salt formation even at 30 GPa. Apart from the thermodynamic and kinetic control during crystallization, pressure acts as a key control for organic acid-base adducts.

Assessment of mBEEF and RPBE exchange-correlation functionals for describing the adsorption of C2H2 and C2H4 on transition-metal surfaces
Authors: Miyazaki Ray , Faraji Somayeh , Levchenko Sergey V. , Foppa Lucas , Scheffler Matthias
Published: May 2024

Describing the interaction between reactive species and surfaces is crucial for designing catalyst materials. Density-functional approximation is able to quantitatively model such interaction, but its accuracy strongly depends on the choice of exchange-correlation (XC) functional approximation. In this work, we assess the performance of mBEEF and RPBE functionals for describing the interaction of C2H2 and C2H4 with (111) surfaces of Cu, Pt, Pd, and Rh face-center-cubic transition metals. In particular, we study the geometry and the vibrational frequencies associated with the adsorbed molecules, as well as the adsorption energies. Crucially, experimental values for vibrational frequencies of molecules adsorbed on the metal surfaces are available for more system compared to physical quantities typically used to benchmark of XC functionals, such as adsorption energies. Thus, vibrational frequencies can be utilized as reference to assess the reliability of the exchange-correlation functionals. We find that the mean percentage errors (MPEs) of RPBE and mBEEF with respect to reported experimental values of vibrational frequencies are 0.64% and -3.88 %, respectively (36 data points). For adsorption enthalpy, RPBE and mBEEF provide MPEs of 27.61 and -59.81%, respectively, with respect to reported experimental values (7 data points). Therefore, the performance of RPBE is superior to that of mBEEF for the considered systems.
Electrolyte stability and instability in lithium-ion batteries
Authors: Terreblanche Jason S. , Luo Tongjun , Piper Louis F. J. , Dose Wesley M.
Published: May 2024

The development of stable electrolyte solutions is critical for improving the lifetime and performance of lithium-ion batteries. Electrolyte instability is a prominent issue with many next-generation electrode materials, such as Ni-rich cathodes, with recent reports identifying ethylene carbonate (EC) as a bad actor at the cathode surface. In this letter, electrochemical methods, operando pressure measurements, and post-mortem X-ray and solution NMR studies were combined to investigate electrolyte degradation phenomena in Ni-rich NMC/graphite full cells with EC-containing and EC-free electrolytes. One key finding is that the mechanism for improved performance in EC-free electrolyte arises from improved stability at both electrode-electrolyte interfaces. Suppressed solvent oxidation reactions at the cathode, and hence less formation and cross over of acidic species, combined with a graphite SEI more resilient towards acid-mediated decomposition, are shown to be important to improve capacity retention. These insights are helpful to understand and mitigate degradation in cells with Ni-rich cathodes.

O texto aponta para as noções de polifonia e de musicalidade como alicerces de uma experiência cênica que abarque a multiplicidade de vozes operadas por atores em cena, de modo a superar fronteiras entre as linguagens.
Daqui do Cariri
Authors: Barbosa Maria Lucivania de Lima
Published: May 2024

Aborda-se no texto a discussão sobre a atuação polifônica na perspectiva da prática de encenadoras do Cariri, sul do Ceará, que exercem mais de uma função na composição cênica e veem o processo criativo como um lugar de ampliação dos saberes, exercendo com isso a função como mediadoras do fazer teatral, potencializando a formação de artistas para o desempenho da atuação polifônica. A pesquisa dialoga com a ideia de atuação polifônica defendida por Ernani Maletta (2016), que implica na busca por um fazer artístico que responda a própria imagem polifônica do teatro, em que o indivíduo, ao assumir o seu papel na criação, possa se apropriar dos demais discursos que compõe a materialidade cênica.
Encenação polifônica
Authors: Maletta Ernani
Published: May 2024

O autor, inicialmente, apresenta seu entendimento sobre o Teatro, que considera uma arte de natureza polifônica, fruto da simultaneidade equipolente de quatro instâncias discursivas: imagem, palavra, movimento e som. Ressalta incoerências entre essa natureza e os processos criativos dos quais participou, destacando a maior valorização de algumas dessas instâncias durante a montagem, bem como da voz do diretor. Em seguida, o autor apresenta sua proposta de criação teatral fundamentada no conceito de polifonia, denominada encenação polifônica e organizada em oito momentos cujos princípios e procedimentos são descritos e analisados.

PIX AND INFORMAL INSTALLMENT SALES: THE IMPACT ON THE ACCOUNTING AND MANAGEMENT OF MICRO-ENTREPRENEURS
Authors: Silva Lincoly Leandsson Fernandes da , Macêdo João Marcelo Alves , Cabral Luiz Marcelo Martins do Amaral Carneiro , Moura Ariane Silva
Published: May 2024

Objective: To analyze the adoption and use of the instant payment system, in parallel with informal installment sales, and its impact on the accounting and management of microentrepreneurs.
Theoretical Framework: Microentrepreneurs face a major challenge in the business environment, which is the management of receipts. Since many of these do not occur at the time of sale, they use installment sales. Especially the informal ones, which in some places are called "fiado" or "pendura", as well as the "caderninho" (little notebook), alluding to the note for later payment.
Method: The methodology involved a literature review covering PIX and its impact on informal commerce and business management. It also involved field research with microentrepreneurs and consumers using an electronic form.
Results and Discussion: The findings highlight that the adoption of Pix has provided a more convenient and agile payment experience for consumers, especially in informal installment transactions. This has positively influenced consumer behavior, increasing the propensity to make installment purchases and generating greater loyalty. However, the implementation of PIX also presents challenges for microentrepreneurs, especially in terms of adapting accounting systems and financial management. The need to guarantee the security of transactions and comply with additional tax obligations is also highlighted as a concern for microentrepreneurs.
Research Implications: This study has demonstrated that the adoption and use of PIX in informal installment sales has a significant impact on the accounting and management of microentrepreneurs, albeit with a limited scope of analysis.
Originality/Value: These findings contribute to a more comprehensive understanding of the effects and encourage further research into this technological innovation in the contemporary business context.

Якість є одним із факторів, що забезпечують комерційний успіх та безпеку використання програмного забезпечення. Під якістю розуміють відповідність явним і неявним вимогам різних зацікавлених сторін. Необхідно забезпечити спільне взаєморозуміння між розробниками та користувачами, інженери повинні розуміти значення поняття якості, характеристики та важливість якості для розробленого або підтримуваного програмного забезпечення. Основою забезпечення якості є вимірювання. Вони є основним інструментом керування життєвим циклом програмних продуктів, оцінки виконання планів і моніторингу. Для кількісного визначення якості необхідно виміряти характеристики програмного забезпечення. Стандартизація передбачає уніфікацію вимог до якості, її вимірювання та оцінки. Використання стандартів дає безліч потенційних переваг для будь-якої організації, особливо у таких ключових областях, як вимірювання якості програмних продуктів, інформаційних та вимірювальних систем. Визнані міжнародні організації із стандартизації опублікували серію стандартів ISO/IEC 25000 щодо вимог та оцінки якості систем та програмного забезпечення SQuaRE, яка набуває широкого практичного застосування.

CIDER : ASSISTED AUTOMATION TOOL FOR C++ LIBRARIES TESTING
Authors: Hulevych Mykhailo
Published: May 2024

Software testing is one of the most important parts of a product development lifecycle (PDL). Companies face significant risks associated with program failures, including financial and reputational ones, having an interest in investing time and money in new testing and quality assurance practices. The programs written in C++ are known as high performant, but complex due to the language specifics. At the same time automated tools that are available mostly for GUI programs can't help with native modules regression testing. Thus, even partial automation of such processes can have a positive effect on PDL in terms of regression testing effectiveness. The article considers a testing technique of recording and playback of program execution on the component level. The proposed tool generates testing scenarios during the execution of a program, giving the ability to perform manual testing and extend the automated component tests execution database. The experiments showed that such scenarios' code coverage results are at a high level and tend to improve when applying optimization algorithms.

Favorable Lifestyle Behaviors as Reverse Risk Factors and Treatment for Postpartum Depression
Authors: Brunson Abigail , McLean Marnie K. , Parker-Brown Jasmin , Whitney Jamie , Lane Abbi
Published: May 2024

Background. Lifestyle behaviors such as sleep, sedentary behavior, physical activity (PA) or exercise, and diet may influence risk for postpartum depression (PPD) or serve as treatment options for those diagnosed with PPD. The purpose of this review was to summarize existing research about four key lifestyle behaviors (sleep, sedentary behavior, PA and exercise, and diet) and their potential influence on PPD. Methods. Studies that were published in English after 2000 were drawn from the PubMed database. Observational studies, systematic reviews, meta-analyses, and randomized, controlled trials that enrolled >50 participants were considered for inclusion. Results. Quality sleep and PA or exercise during pregnancy and the postpartum period may reduce PPD risk or help improve PPD symptoms. Data regarding the utility of intervening on diet patterns or specific nutrients for lessening PPD risk or serving as PPD treatment are inconsistent. Evidence for vitamin D supplementation is extensive, while evidence supporting other vitamins, nutrients, and minerals remains inconclusive. Research linking sedentary behavior and PPD is extremely limited. Conclusion. Sleep quality and PA or exercise may reduce the risk of PPD or mitigate its symptoms. Further high- quality research studies examining the relationship between sedentary behavior and PPD risk are necessary. Healthy lifestyle behaviors, alone or in conjunction with other evidence-based strategies recommended by healthcare providers, may serve as effective preventive measures and treatments for PPD in the pregnancy and postpartum periods.

Topicality. One of the most important aspects in the field of sports is determining the appropriateness of the loads used for the adaptation capabilities of the athletes' bodies. This is a key element in both the training and competition process, which requires immediate correction and the development of effective training systems with long-term prediction of results, not only in mixed martial arts, but in all other sports as well. The Purpose of the Research. To study the peculiarities of the correlation between the parameters of the working weight of the projectile and adaptive changes in the body of mixed martial arts (MMA) athletes in the process of special strength training. Methods. 50 shock style MMA athletes aged 19±0,7 took part in the study. Two research groups were formed. The representatives of the examined groups used experimental regimens of training sessions during 3 months of strength training. Correlation analysis was carried out between parameters of projectile working mass (m) and biochemical indicators of blood, anthropometry, bioimpedancemetry, control testing of the development of maximum strength of athletes. The Results. In the athletes of the first group at all stages of the study, it was found that a constant strong positive relationship (r>0,70) is observed between the indicator of the working mass of the projectile (m=56–59 % of 1 RM) in the conditions of the regime of type A training loads (Ra=0,56) and the development of the maximum strength of leg muscles during the exercise «leg press on the block» (r=0,73), as well as the basal level of lactate dehydrogenase enzyme concentration in blood serum (r=0,72). The analysis of the results of the study obtained after 3 months of special strength training by the athletes of the second group of C-type training loads (Ra=0,74) indicate that the number of strong correlations has increased 9 times compared to the data found at the beginning of the experiment. It was established that the largest change in the level of correlations from moderate at the beginning of the study (on average r=0,57) to high after 3 months of training (on average r=0,87) occurred between the projectile working weight indicator and the results of the control testing the development of maximum muscle strength (chest muscles, shoulder and hip muscles) during control exercises. Findings. It was established that only among the athletes of the second group, who in the process of special strength training use the mode of training loads of type C (Ra=0,74), the correlations increase during 3 months of training, which indicates pronounced processes of long-term adaptation.

Topicality. In the modern system of training in mixed martial arts, in particular in the sport of horticulture, the search for optimal models of training programs aimed at improving strength capabilities and body composition of athletes is actively investigated. The Purpose of the Research. To study the peculiarities of the influence of different models of strength training in horting on the indicators of the body composition of athletes.. Methods. 60 athletes who have been involved in horting for 3–4 years took part in the study. 3 research groups were formed. The representatives of the examined groups used experimental training models during 3 months of strength training. Using the non-invasive method of bioimpedance measurement during all stages of the study, the nature of changes in parameters of body composition indicators was assessed. The Results. It was established that only representatives of the 2nd group showed a positive increase in parameters of active cellular body mass (ACM, %) by 3,7 % (p<0,05) during the 3 months of the study compared to the initial data. A significant decrease in the parameters of this body composition indicator was found in the athletes of the other two groups. The greatest increase in BJM among the participants was found in athletes of group 3. At the same time, in representatives of group 1, the level of the studied indicator is almost half as low as compared to the results that were found in athletes of group 3 during the three months of the experiment. The greatest dynamics towards a decrease in the BM indicator (%) by 2,8 % (p<0,05), over the entire period of the study, is observed in athletes of group 1. At the same time, in the representatives of the other two groups, during the entire period of the experiment, we observe identical dynamics of the investigated body composition indicator, the level of which differs by only 0,7 % from the results demonstrated by the athletes of the 1st group. Findings. The use in the process of strength training in horting of variations of exercise complexes effective in strength fitness on simulators under the conditions of the principle of “premature fatigue” of agonist muscles due to exercises of an isolating nature, allows to maximally influence the parameters of body composition compared to the results that were found in other conditions of training activities.

Bu araştırmada, Ti6Al4V alaşımının ortogonal tornalama işleminde ilerleme hızının kesme kuvveti ve talaş morfolojisi üzerindeki etkilerinin sonlu elemanlar analizi gerçekleştirilmiştir. Enerjiye dayalı sünek hasar kriteri kullanılarak ortogonal tornalama sürecini modellemek için iki boyutlu (2B) sonlu elemanlar (FE) modeli oluşturulmuştur. Daha sonra, ilerleme hızının kesme kuvveti ve talaş morfolojisi üzerindeki etkileri tartışılmıştır. Tahmin edilen kesme kuvvetinin deney sonucuyla iyi uyum sağladığı ve karakteristik uzunlukla kontrol edilen hasar enerjisi kriterinin, kesme kuvvetlerini kabul edilebilir bir doğrulukla hesaplamak için kullanılabileceği bulunmuştur. Ti6Al4V alaşımının tornalanmasında testere dişli talaş şeklinde gözlemlenen talaş morfolojisi üzerinde ilerleme hızının büyük bir etkisi vardır. İlerleme hızının artmasıyla kesme kuvvetinin dalgalanma genliğinin keskin bir şekilde arttığı, ancak frekansın azaldığı gözlemlenebilir.

This multiple case study examines less-proficient Intermediate EFL students' attitudes toward the use of Grammarly's free version in writing. The study explored the participants' behavior, cognition, and affect, aiming to provide detailed insights into their experiences and perspectives. Utilizing Zoom recordings, stimulated recall, and semi-structured interviews, the study reveals that the less-proficient learners were product-oriented in revising their writing, showing low cognitive engagement with Automated Written Corrective Feedback (AWCF). Although one participant did not fully trusted Grammarly’s accuracy, all of them accepted its suggestions quickly and uncritically. The desire to increase the scores seemed to play a significant role in their engagement with AWCF. Despite this, the study primarily highlights how inadequate linguistic knowledge posed challenges for the students in effectively utilizing the technology. Nonetheless, the students expressed overall satisfaction with Grammarly's assistance, recognizing its ability to improve their drafts. To optimize the technology's benefits for less-proficient EFL students, the study the need for providing metalinguistic knowledge and user training to enhance their language learning through its feedback.

The past decade has witnessed the global rise of policy innovation labs (PILs), many of which are nonprofit organizations. Policymakers have promoted PILs as a novel approach to addressing pressing economic and social issues. Concurrent with the growing importance of PILs has been the shift to public value management (PVM), which focuses on policy outcomes that benefit the public and the needs and problems in society. One relatively new process raised in the public managementliterature is co-experience, which considers stakeholders' engagement with public policies or programs within the broader context of life experience. This, the authors argue, is an important contribution to public value creation. Social media platforms such as Twitter (now X) are one tool that PILs can employ to assess and develop stakeholder co-experience. The authors analyzed 13,009 Twitter messages largely generated by stakeholders relating to 42 U.S.-based PILs.

Maros-Pangkep karst formation in South Sulawesi is one of the largest karst environments in the world.  One cave located in the area is Leang Londrong and is a part of the management of Bantimurung-Bulusaraung National Park. The Leang Londrong area is known as tourism spot with water-based tourism as the main attraction and it is also known as the main ecosystem service provider in particular as water sources for many areas. This cave is inhabited by some species of bats. Even now the area is designated for water-based tourism, other potential tourism object such bats roosting inside the cave for tourism development has not been explored. Therefore, this study attempts to examine the perception of local community and tourists visiting the area towards nature, cave, bats and its conservation, as well as cave-bats tourism development.  The study was conducted between January-April 2022 by distributing questionnaires to 86 respondents consisted of local community, tourists, and government’s representatives.  The results indicated that in general the respondents had limited knowledge on nature, cave, bats and its conservation. In particular with bats, the majority of the respondents have not yet been familiar with bats, understood the roles of bats for the environment, and tended to ignore the existence of bats. However, in relation with nature and conservation, bat conservation, and the development of cave and bat tourism in Leang Londrong, all respondents from the tourist’s side agreed to support (>85%) and for the locals, the number was even higher (>90%).  Therefore, from the perspectives of local community and tourists, the chance in developing cave and bat tourism in Leang Londrong can be considered possible.
