Published: February 2025

Objetivo: Analisar o perfil vacinal infantil no Brasil, com ênfase na Paraíba e nas cidades de Campina Grande e João Pessoa. Métodos: A pesquisa, de caráter ecológico, documental e descritivo, utilizou dados do DATASUS coletados entre maio e dezembro de 2024, com abordagem quantitativa e análise estatística. Resultados: No Brasil, a vacina Tríplice Viral D1 apresentou a maior cobertura, enquanto a vacina contra Varicela registrou a menor adesão. Na Paraíba, a Tríplice Viral D1 também liderou, enquanto a vacina contra Febre Amarela teve menor cobertura. Em Campina Grande e João Pessoa, as taxas de vacinação foram menores entre 2020 e 2022, período marcado pela pandemia da Covid-19. Apesar de algumas vacinas alcançarem boa cobertura, poucas atingiram as metas do PNI. Conclusão: Os resultados destacam a necessidade de estratégias como campanhas educativas e capacitação de profissionais de saúde para ampliar a cobertura vacinal e enfrentar a hesitação vacinal. O programa "Vacina Mais Paraíba" demonstrou que ações estruturadas e colaborativas, envolvendo governo e população, são essenciais para aumentar as taxas de imunização e proteger a saúde infantil.
Der Einfluß der Donorzahl des Lösungsmittels auf chemische und elektrochemische Vorgänge
Authors: Gutmann V.
Published: February 2025

Complex formation in donor solvents is favoured by decreasing donor number of the solvent molecules and by increasing donor number of the ligand to be coordinated. The solvation of metal ions is discussed for both hard and soft ions. It is shown that the solvation entropies are negative and contributing considerably to the free enthalpy of solvation when the metal ions are hard. The ionising properties of a solvent are shown to be related to the donor properties of the solvent molecules.
Zur Herstellung von Malonsäuredinitril
Authors: Zinsstag C. , Peake R.J.
Published: February 2025

When working with cyanacetamide, the usual method of catalytic dehydration of amides to give the corresponding nitriles is unsatisfactory. In this particular case the high temperature and the presence of ammonia causes decomposition to occur. This can be overcome by passing cyanacetamide vapour at < 5 Torr over silicaphosphate catalyst at 350 to 400 °C in the absence of ammonia to produce malonodinitrile. However more recent work shows that triethylphosphate can be used advantageously for the same purpose at 700 °C.
Die elektrochemische Bestimmung des im Wasser gelösten Sauerstoffs in Anwesenheit von Schwefelwasserstoff
Authors: Schmid Marcel , Mangy Khalil H.
Published: February 2025

This paper introduces an electrochemical method for DO measurements in the presence of hydrogen sulfide by means of membrane electrodes. The electrode is covered by a multilayer membrane system. A KOH layer near the electrode surface serves as the electrolyte. Another layer consists of a metal salt, in this case Cd(NO3)2, which is separated from the first layer by a membrane. H2S will react with the metal ion and is thus kept from penetrating through the electrolyte layer to the electrode surface. This electrode system will be helpful for kinetic studies in the H2S-O2 system and for oxygen measurements at the bottom of lakes or in sediments.
Untersuchungen an ternären und quaternären Fluoriden III : Fluortrirutile und weitere Lithiumhexafluorometallate, LiMeIIMeIIIF6
Authors: Viehbahn W. , Rüdorff W. , Hänsler R.
Published: February 2025

Quaternary fluorides of the formula type LiMeIIMeIIIF6 (MeII = Mg, Ni, Co, Zn; MeIII = Ga, V, Cr, Fe) cristallize in the tetragonal trirutile type. Against that LiCuCrF6 has the mono-rutile structure. The formation of solid solutions rutile- trirutile is observed by exploring the system ZnF2–LiZnCrF6 as example.
LiMnCrF6 crystallizes in the Na2SiF6-structure, space group P321 with a = 8,654 Å and c = 4,731 Å. Larger MeII-ions (Ca, Sr and Cd) form another hexagonal structure, probably the K2MnF6-type, space group P63mc.
In the compounds LiMeIIMeIIIF6 containing one paramagnetic cation (Co, Ni) only small deviations from normal paramagnetism are observed, whereas compounds with two paramagnetic cations MeII and MeIII show stronger antiferromagnetic coupling.
The reflection spectrum of Cr3+-ions in CrF3 and in some ternary and quaternary fluorides is surveyed and discussed.

Published: February 2025

Background: Surgical management of a child is a life stage in its own right. It generates anxiety for the child and their parents. The management of preoperative anxiety is a major issue in improving the quality of care and avoiding potential psychological repercussions. Different procedures can partially reduce anxiety, especially the presence of the parents, accompaniment to the operating room with a toy, etc. However, in France, during a surgical procedure, only 4% of parents are present at anesthetic induction. Thus, the development of a comprehensive support procedure including, in particular, parental accompaniment, would appear necessary.Aim: To compare, at the time of anesthetic induction, the level of anxiety of children aged 5 to 12 years between the group having benefited from a comprehensive support procedure and the control group benefiting from the usual care.Method: This was a randomized, open-label, comparative pilot study. One group of children benefited from the overall support procedure including: an explanatory booklet of the patient pathway given to the child during the pre-anesthesia consultation, the viewing of a film showing the places and different stages as well as the explanation of the parental presence in pre-anesthesia and during recovery.Results: 47 children participated in the study, the average age was 8 years. Median anxiety as measured by the Modified Yale Preoperative Anxiety Scale was 22.9 compared to 36.5 for the control group, with no statistically significant difference. It should be noted that a score of less than 25 indicates that the patient has no anxiety.Conclusion: The specific support procedure developed in our study appears to be able to improve child anxiety, despite the low sample size. A larger, multicenter study would yield statistically significant results.
Реализация преобразования удаления приватных переменных в последовательных Fortran-программах для их эффективного распараллеливания на вычислительные кластеры в системе SAPFOR
Authors: Колганов А.С. , Гусев Г.Д.
Published: February 2025

Процесс автоматизированного распараллеливания программ может быть существенно затруднен из-за их структуры и оптимизации под последовательное выполнение. Из-за этого полученная параллельная версия может быть неэффективной, а в некоторых случаях распараллеливание оказывается и вовсе невозможным. Решить указанные проблемы помогают преобразования исходного кода последовательных программ. В данной статье рассматривается разработка алгоритма преобразования последовательных Fortran-программ “удаление приватных переменных” и его реализация в системе автоматизированного распараллеливания SAPFOR (System FOR Automated Parallelization). Применение реализованных преобразований в системе SAPFOR продемонстрировано на четырех прикладных программах, входящих в пакет NAS Parallel Benchmarks.

The process of automated parallelization of programs can be significantly complicated due to their structure and optimization for sequential execution. Because of this, the resulting parallel version may be ineffective, and in some cases parallelization turns out to be completely impossible. Transformations of the source code of sequential programs help to solve these problems. This article discusses the development of an algorithm for transformation of sequential Fortran programs called “removing of private variables” and its implementation in the SAPFOR automated parallelization system (System FOR Automated Parallelization). The application of the implemented transformations in the SAPFOR system is demonstrated on four application programs included in the NAS Parallel Benchmarks package.

Authors: Шахгираев И.У. , Диндигова М.А. , Мукаева Ш.С.
Published: February 2025

В статье проведено исследование сущности понятия «мониторинг» и определено, что большинство ученых используют его, заменяя понятие «анализ». Однако мониторинг – это понятие более широкое, которое сочетает в себе различные направления анализа: производственно-хозяйственный, финансовый, инвестиционный, технический, технологический, социальный, инновационный, экологический и т.д. и выступает его комплексным проявлением. Поэтому целесообразнее использовать понятие «комплексный мониторинг», которое является более полным и разносторонним аналитическим исследованием, учитывающим результаты различных видов деятельности предприятия, которые формируются под влиянием внутренних и внешних факторов и служит базой для определения направлений дальнейшего функционирования и развития, в том числе составляет базу для проведения стратегического анализа. Комплексный мониторинг выполняет задачи ретроспективного и текущего анализа, что является основным отличием от стратегического анализа, который предусматривает проведение аналитического исследования на перспективу для разработки стратегического плана и определения стратегии развития предприятия. Комплексный мониторинг и стратегический анализ занимают важное место в системе управления, поскольку решают одну из главных его задач – качественное формирование стратегического плана и стратегии развития предприятия.

Published: February 2025

The purpose of this article is to understand the perceptions of parent commissioners, elected commissioners, and principals on the political participation of parents in the decision-making process within the councils of commissioners since the adoption of Bill 105 amending the Education Act. A multiple case study was conducted with two school boards in the City of Québec area, and semi-structured interviews were held with 13 participants. A content analysis of the data revealed that greater numbers and the right to vote have brought parent commissioners more legitimacy and recognition, as well as a more egalitarian relationship with the other members of the school governing bodies. The role of parent commissioners is now more decision-making than simply advisory.

Objective to develop an algorithm for the management of patients with VS in combination with HC (occlusive, open with increased pressure, normal pressure).Materials and methods. 76 patients with VS in combination with HC were treated at the subtentorial neurooncology department in 2017‒2023. All patients were examined by an ophthalmologist before surgery, in the early postoperative period and at repea­ted examinations after 3, 6 and 12 months. Standard preoperative procedures included CT scan, MRI brain examination with cont­rast, CT scan on the first day after sur­ge­ry, MRI with contrast in the early postoperative period – before discharge, and MRI with contrast in 3, 6 and 12 months. All patients were distributed in subgroups depending on the severity of symptoms of both hydrocephalus and VS, general somatic condition according to the ASA scale and age, and the most reasonable treatment tactics aimed at preserving the quality of life was used.Results. Depending on the type of HC and treatment algorithm patients were divided into 6 groups: I included 37 patients with VS and occlusive or open HC with increased pressure (OOHCIP) and papilledema. In these patients the 1st stage consisted of ventriculoperitoneal shunting (VPS), 2nd – VS removal; II – 6 patients with OOHCIP: 1st – VS removal, 2nd – VPS in whom HC not regressed; III – 13: 6 of whom OOHCIP and 7 with normotensive HC (NHC) – all VPS and observation in dynamics; IV – 9 with VS and NHC underwent VS removal and given the regression of HC VPS was not performed; V – 7 with VS and NHC in whom there was no HC regression after VS removal therefore the 2nd – VPS was carried out; VI – 4 with VS and vicarious HC underwent removal of VS and dynamic observation. Karnofsky scale increased more then 20 % was in groups I, III (OOHCIP), IV and V.Conclusions. For patients with OOHCIP and papilledema, the optimal tactic is 1st – VPS, 2nd –removal of VS. For elderly patients with VS in combination with normotensive or connective HC with increased pressure and concomitant pathology and predominance of HC symptoms it is recommended to conduct first step or only VPS under the follow up and VS removal in case of tumor/clinical signs progression.

ADVANCES IN THE MEASUREMENT OF FUNDAMENTAL CONSTANTS
Authors: Gurikar Shivaraj G
Published: February 2025

Advances in the measurement of fundamental constants have played a pivotal role in refining our understanding of the physical universe. Fundamental constants, such as the speed of light (c), the gravitational constant (G), Planck's constant (h), and the charge of the electron (e), are crucial for the accuracy of scientific theories and models across various fields, from particle physics to cosmology. Recent innovations in experimental techniques, instrumentation, and quantum technologies have enabled significantly improved measurements of these constants, contributing to greater precision in scientific research and the redefinition of SI units. A landmark achievement in this area was the redefinition of the International System of Units (SI) in 2019, where key units, including the kilogram and the ampere, were redefined based on fixed values of fundamental constants. This development eliminated reliance on physical artifacts, ensuring greater stability and universality in measurements. Notable advancements include the use of Kibble balances for determining Planck's constant and optical lattice clocks for measuring time with unprecedented precision.Quantum technologies, such as quantum sensors and optical frequency standards, have also revolutionized fundamental constant measurements by providing greater sensitivity and accuracy. Techniques such as atom interferometry and quantum entanglement have made it possible to refine constants like the fine-structure constant (α) and the gravitational constant (G), while also testing their potential variations across space and time. These advances not only improve the precision of current measurements but also open new avenues for exploring potential new physics beyond the Standard Model. Continued progress in measurement techniques promises to deepen our understanding of the universe, providing valuable insights into the fundamental laws that govern the natural world.

Published: February 2025

One important responsibility in the diagnosis of cardiac sickness is the identification of intracardiac masses in echocardiograms. For the purpose of improving diagnostic precision, a new fully automated sparse representation-based classification method is introduced for the detection of intracardiac tumours and thrombi in echocardiography. To find the mass area, first a region of interest is cut. After that, the speckle is removed while the anatomical structure is preserved using a new global denoising process. Afterwards, a modified active contour model and K-singular value decomposition are used to depict the mass's contour and its associated atrial wall. Lastly, in order to distinguish between two masses, a sparse representation classifier processes the motion, boundary, and texture data. For this purpose, we gather 97 clinical echocardiography sequences.
EXPLORATION OF QUANTUM MECHANICS IN EVERYDAY PHENOMENA
Authors: Gurikar Shivaraj G
Published: February 2025

Quantum mechanics, the branch of physics that deals with the behavior of matter and energy at atomic and subatomic scales, may seem like a highly theoretical subject confined to laboratories, but its principles are deeply embedded in our everyday lives. This study explores the profound influence of quantum mechanics on various phenomena and technologies that shape modern society. Concepts such as wave-particle duality, superposition, and quantum entanglement, though initially counterintuitive, provide explanations for numerous occurrences and innovations in our daily existence. One of the most visible impacts of quantum mechanics is in the realm of technology. Semiconductors, integral to devices like smartphones, computers, and televisions, operate on principles of quantum mechanics, enabling the development of advanced electronics. Additionally, quantum phenomena underpin technologies such as lasers, LEDs, and MRI machines, revolutionizing fields from medicine to communication.Quantum mechanics also plays a crucial role in natural processes, such as photosynthesis, where quantum coherence boosts energy efficiency in plants. In the biological realm, quantum effects influence senses like smell and vision, adding another layer to the complexity of life. Even the colors we see in objects or the efficiency of solar panels are outcomes of quantum principles at work. Beyond practical technologies, quantum mechanics challenges our fundamental understanding of the universe. Concepts like the uncertainty principle and quantum superposition disrupt classical views of reality, leading to new perspectives on causality and measurement. As quantum research progresses, its applications are poised to expand further, potentially leading to breakthroughs in fields like quantum computing, cryptography, and energy systems. This exploration emphasizes how quantum mechanics, despite its abstract nature, is central to both the technologies and the natural phenomena that define our everyday experiences.

The COVID-19 pandemic has impacted various economic sectors, including healthcare. During the pandemic, there was a surge in demand for healthcare products, accompanied by challenges such as supply chain disruptions and rising operational costs. After the pandemic, the sector faced declining demand for the products and challenges in adapting business strategies. These impacts influenced financial performance. This research aims to analyze differences in the financial performance of healthcare companies listed on the Indonesia Stock Exchange before, during, and after the pandemic. Financial performance is analyzed using liquidity, activity, debt, and profitability ratios to provide a comprehensive overview of the pandemic's impact on the sector. This quantitative research using an event study the COVID-19 pandemic. Data analysis is conducted using Wilcoxon Signed Rank test. The results show no differences in financial performance for liquidity, activity, debt, and profitability (Net Profit Margin and Return on Equity). However, profitability (Return on Assets) shows differences between the periods before and during the pandemic, as well as during and after the pandemic. This is attributed to the surge in demand for healthcare products during the pandemic, which improved financial performance, particularly profitability ratios. However, after the pandemic, some financial performance indicators, such as net profit margin and debt ratio, declined, reflecting the healthcare sector's adjustments to post-pandemic market conditions.

Este estudo tem como tema “Aprendizagem colaborativa”, com o objetivo de discorrer sobre como a aprendizagem colaborativa remete à interação e à coparticipação com o objetivo de alcançar trocas expressivas, levando a um modelo de aprendizagem distinta. Esse modelo remete a metodologia de ensino e aprendizagem: aprender ensinando e ensinar aprendendo. Ao analisarmos a presença das tecnologias educacionais, constatamos que a aprendizagem colaborativa amplia as probabilidades do recurso tecnológico implantado no processo de aprendizagem. Os alunos são reunidos em torno de um computador para descobrir diversos assuntos, durante as atividades, em ocasiões diferentes, uns instruem enquanto outros aprendem. Ou seja, as atividades são desenvolvidas em grupo, em que os alunos interagem de forma recíproca, colaborando todos para o mesmo fim, a produção colaborativa e os conhecimentos compartilhados. É neste contexto que expomos a relevância de aprender por meio da aprendizagem colaborativa, destacando as tecnologias digitais e sua importância como recurso de ensino. A ideia é aproximar os recursos utilizados da realidade do aluno, escolhendo dispositivos que possam ser instrumentos de desenvolvimento de uma aprendizagem significativa.
Mother's Milk
Authors: Aranoff Deena
Published: February 2025

This book engages with an age-old question: What accounts for the persistence of Jewish culture through the ages? Despite significant variations, how were Jewish cultural elements sustained over millennia?Mother's Milk: Essays on Child-Rearing, the Household, and the Making of Jewish Culture expresses the idea that a stage of the human experience is excluded from Jewish culture that includes the earliest phases of child-rearing in household context. Author Deena Aranoff argues that the inclusion of child-rearing would help strengthen the idea that Jewish cultural production is not restricted to the channels of rabbinic and literary activity alone.Mother's Milk expresses how Jewish practices, including rabbinic halakhah, are derived from household custom and maternal care in particular. Aranoff encourages us to revise the genealogy of Jewish culture to allow for dialectical interplay between everyday life and formal Jewish practice.

Background: Diabetes mellitus is a chronic disease affecting a reasonable percentage of people globally, recording high incidence, chronicity and mortality. There are challenges in curbing the burden due to high care cost resulting in adopting cost-saving strategies through use of plant foods. High calorie diets and legumes including culturally acceptable staple foods like cocoyam, soya bean and Bambara groundnut are undergoing experimental studies for their clinical application in the management of T2DM. This study is focusing on understanding the relationship between high calorie diets and hyperlipidaemia, due to the relevance of such knowledge in cardiovascular diseases.
Methodology: Three commonly consumed plant foods: Cocoyam (CY), Bambara groundnut (BGN) and Soya bean (SB) were obtained, processed, and pelletized after samples of the flour were subjected to proximate analysis and energy content calculation. The intervention feeds were given for 28 days to the seven groups of male albino rats that were induced with diabetes using Streptozotocin, Blood specimen was collected, from the intervention groups and controls for lipid profile determination.
Results & Discussion: SPSS and one-way ANOVA were used to analyze the generated data, while the Turkey`s post-hoc test, was applied to detect the difference in mean, with the significant difference pegged at p<0.05 value. Group A treated with Formulation 1 (16.6%CY: 16.6%SB: 16.6%BGN: 50%RF), which in comparison to the diabetic control, reduced the Total cholesterol (TC) level by 12.53% and the Low-density lipoprotein cholesterol (LDLc) levels by 24.71%. Formulations 1`s 16.3kJ/g and commercial rat feed (RF)`s 16.7kJ/g energy values were comparable and with 65.7% higher fibre content compared to RF, might have contributed to its hypocholesterolaemic potency. Formulation 7, a binary blend (50%SB + 50% RF), with the highest fat content (19.55%) and highest energy value (23.8kJ/g), had comparatively lower potency than formulation 1 and RF.
Conclusion: CY-BGN-SB flour blend formulations contained caloric values that approximated that of commercial rat foods and despite the higher fat content in some of the formulations they all exerted hypolipidaemic effects possibly due to reasonable number of dietary fibres and hypoglycemic-bioactive constituents, and hence can be recommended for nutritional management of diabetes especially if human studies are conducted.
