Published: November 2024

The study and development of cement pastes are essential to determine the properties of matrices with cement for oil wells. Using different mixtures and adaptations requires analysis and verifications for each product generated. Thus, it is observed that additions and additives can contribute to forming cement matrices with predetermined properties. Thus, this work presents the study of the viscosity of pastes through the Marsh Funnel and Mini-Slump tests using mixtures with oil well cement (OWC) with additions of micro silica and superplasticizer in different proportions. In this context, a 3³ factorial experimental design and replications are presented considering the variables of active silica content, water/binder ratio (w/c), and superplasticizer content. The Statistica software obtains the response surface and different significance coefficients for each variable and their interactions in the process, thus optimizing the matrix for the desired cement paste. Finally, the statistical influence of each of the variables analyzed is analyzed, observing that the proportion between cement and silica is mainly relevant to the viscosity of the paste.

Introdução: A síndrome de Sjogren (SS) é uma doença sistêmica e crônica, de caráter autoimune, em que ocorre o acometimento de glândulas salivares e lacrimais, que resultam em xerostomia e xeroftalmia, além de sintomas extraglandulares, como fadiga, dor musculoesquelética, afecções pulmonares, renais, hepáticas e neurológicas. Devido a ampla gama de manifestações clínicas, a avaliação médica desses pacientes torna-se desafiadora. Objetivo: Elucidar os aspectos fisiopatológicos, clínicos, diagnósticos e terapêuticos da Síndrome de Sjogren. Metodologia: Trata-se de uma Revisão Integrativa de literatura, que utilizou as bases de dados MEDLINE/PubMed, SciELO, LILACS e Cochrane Library,  desenvolvida em seis etapas, objetivando responder a pergunta norteadora desenvolvida pela estratégia PICO. Resultados e Discussão: A SS é uma doença multifatorial, com alguns polimorfismos reconhecidos (HLA -DR e TNF-a), porém a patogênese específica ainda não está totalmente elucidada. 90% dos pacientes apresentam xerostomia e 95% xeroftalmia. A artrite e artralgia estão entre as manifestações extraglandulares mais comuns da SS. O diagnóstico envolve o quadro clínico, evolução e a detecção de determinados anticorpos, após a exclusão de diagnósticos diferenciais. O tratamento é principalmente sintomático, com objetivo de melhorar a qualidade de vida do paciente. Conclusão: A SS apresenta ampla variedade de manifestações clínicas, com morbidade significativa. É necessário uma abordagem abrangente para que o diagnóstico preciso e adequado seja realizado. A SS ainda carece de consenso acerca dos critérios de classificação e de aspectos terapêuticos, que estão em evolução constante, evidenciando a necessidade de pesquisas futuras.
UMA ABORDAGEM EPISTEMOLÓGICA SOBRE O CONCEITO DE TEMPO DE UM GRUPO DE ESTUDANTES
Authors: Andrade Gustavo de , Duarte Marcus
Published: November 2024

A Relatividade transformou a Física absoluta, descrito pela Física Clássica, em relativa, descrito pela Física Moderna. Além disso, características do universo antes vistas como sólidas, como o espaço e o tempo, se desmancharam no ar, o que trouxe mais inquietações sobre a natureza. Especificamente o espaço e tempo, que no cotidiano são absolutos, o que leva a questionar acerca do impacto da Física Moderna na percepção das pessoas sobre esses conceitos. A relatividade está muito presente na cultura, quer seja na educação formal quer seja em espaços informais. No entanto, a compreensão da Física Moderna não é algo trivial, portanto, cabe ao ensino formal esse encargo. Este trabalho objetiva analisar duas turmas do ensino médio, com intuito de avaliar o conceito de tempo dos alunos. O referencial de análise escolhido é o perfil epistemológico desenvolvido por Bachelard. Porém não se trata de se traçar o perfil dos indivíduos, mas sim analisar as expressões usando as classificações propostas por Bachelard com intuito de procurar indícios da evolução conceitual de um grupo de alunos. Os resultados indicam que os estudantes apresentam conceitos de tempo muito ancorados em perfis epistemológicos menos elaborados.

Published: November 2024

Maxillofacial fractures present complex surgical challenges that require precise reconstruction techniques. Image-guided surgical methods, including computer navigation and 3D imaging, are increasingly used to improve surgical outcomes, yet selecting the optimal modality remains difficult due to the varying benefits of each technology.  The databases used in the current research include, but are not limited to, PubMed, Scopus, and Google Scholar for article searches. Controlling for sources of bias, the review selected publications on image-guided surgical approaches to managing craniofacial fractures. Studies were identified based on the following criteria: methodology, relevance and patient-oriented results. Thus, analytical categories were developed to evaluate the results, including surgical meticulousness, complication incidences healing, and overall patient satisfaction. The research shows that the availability of enhanced imaging tools and navigation, including CT-nav, 3D-image ster, and intra-operative CBCT, enhances surgical precision and diagnostic accuracy. Preoperative planning repeatability when using CAN was up to 86.5%, and the need for revisions in maxillofacial trauma patients was reduced. Research on computation mirroring for navigation found differences between 0.12 mm, revealing enhanced surgery accuracy. Evaluations of image-guided techniques indicate their advantage over other methods in maxillofacial fracture operations in terms of accuracy and efficiency. Even nowadays, they provide significant improvements in patients’ treatment and surgical precision despite certain shortcomings in terms of technology and availability. Further studies need to consider enhancements to the navigation systems and consider cost benefits, depending on the type of setting in which the patient is located.
ANGLED DENTAL IMPLANTS: IMPLICATIONS FOR CLINICAL PRACTICE AND BIOMECHANICAL CONSIDERATIONS
Authors: Alves Leonardo Dornelas
Published: November 2024

Angled dental implants have emerged as an effective solution in clinical settings where the placement of straight implants is constrained by unfavorable bone positions or the presence of adjacent anatomical structures. The angulation of implants significantly influences stress distribution around the implant, impacting its stability and longevity. Research highlights that the direction of applied loads is critical, as angled implants can generate greater bending and shear forces compared to straight implants, potentially leading to stress concentrations in surrounding bone. Finite element analysis (FEA) is commonly used to model these conditions, offering insights into stress zones and predicting potential failure areas. Bone quality plays a vital role in how implants respond to applied forces, with denser bones effectively dissipating forces while more porous bones are at higher risk of resorption and integration failure. Studies indicate that excessive stresses on angled implants can lead to bone resorption, compromising long-term stability. Therefore, careful consideration of implant angulation, connection type, bone quality, and thorough surgical planning is essential. Recent studies, including those investigating the effects of implant design and bone density on stress distribution, have demonstrated that varying implant threads and angulated abutments affect the stresses experienced by surrounding bone and implants. The findings emphasize the need for appropriate implant selection and a detailed assessment of bone anatomy and patient-specific clinical conditions. By incorporating advanced technologies like FEA, clinicians can enhance their understanding of biomechanical interactions, ultimately leading to improved clinical outcomes and patient satisfaction. Continuous education and the implementation of best practices in dentistry remain vital for the successful application of angled dental implants.

Published: November 2024

Examining implicit causality and relative clause attachment ambiguity in bilingual participants, this study investigates whether adult second language (L2) English speakers share sensitivity with native speakers to implicit causality (IC) information during online resolution of relative clause attachment ambiguity. L1 Turkish/L2 English speakers and English natives participated in offline sentence completion and online self-paced reading tasks. Results revealed that L1 English speakers preferred high attachment in IC conditions and low attachment in non-IC conditions. In contrast, L2 speakers showed a preference for high attachment in both conditions, suggesting that L2 sentence processing relies more on lexical than syntactic information.

To analyze changes in the vertical dimension of the lower third of the face studied on teleradiograph in L-L following rapid palatal expansion achieved by four-band Hyrax-type rapid palatal expander (RPE) and by acrylic-bonded McNamara RPE to identify the most appropriate therapeutic choice based on the patient's facial growth pattern. 30 patients were selected, of whom 20 (9 males and 11 females with a mean age of 8.285 ± 1.216) were treated using McNamara RPE (Group D), and 10 (6 males and 4 females with a mean age of 8.562 ± 1.152) were treated with Hyrax RPE (Group B), for an average treatment time T0-T1 of 0.96 ± 0.501 years. According to Tweed and Ricketts, Cephalometric tracings obtained from lateral cephalograms at T0 and T1 were analyzed to study changes in the vertical dimension of the lower third of the face. For this purpose, 6 cephalometric landmarks were considered: convexity (distance of point A to the NPg plane), Ricketts’ total face height (angle between the NBa plane and Xi-Pm plane), lower face height (angle between the ANS and Xi-Pm planes), facial axis (angle between the NaBa plane and PtGn plane), ANB angle, and FMA angle. No statistically significant differences were found between the measurements at T0 and T1 for any of the 6 cephalometric measurements considered, neither within the single groups nor when comparing the two. However, a greater increasing trend was found for some variables between the two groups, such as Ricketts' total facial height, lower facial height, and FMA angle, although not statistically significant. Hyrax and McNamara's RPEs have provided minimal changes in the vertical component during palatal expansion treatment, thus demonstrating their ability to preserve the vertical dimension of the face. Therefore, there are no contraindications for using either appliance for patients with dolichofacial growth patterns.

In modern dentistry, implantology is widely used; implants have a survival rate of 96.4-96.9% at 10-year follow-up. In order to obtain aesthetic, health, and performance results of implant restorations, virtual pre-surgical prosthetic planning is essential. For proper planning, the patient’s CBCT data is matched to the prosthetic design in order to virtually plan the three-dimensional positioning of the implant before surgery. The patient, following trauma, had avulsion of elements 1.2, 1.1 and 2.1. The fracture is treated conservatively, and after 3 months, three implants are placed with guided Pilot-Drill surgery and prosthetically guided implant design. To achieve a clean transmucosal path and create good aesthetic profiles, the prosthetic connection's depth was adequate. Periodic professional oral hygiene recall has been essential for the long-term maintenance of the implants. At the follow-up of 6 years, perimplant bone stability and aesthetic and functional satisfaction of the patient were detected. In the field of dental implant placement, bone data, and anatomical restrictions can be processed by guided implant software. In combination with wax-up scans, implant planning will improve the predictability of implant placement. The ideal placement of implants in prosthetically guided implantology is not solely determined by bone anatomy but also by the final position and features planned for the prosthesis. A hybrid solution between traditional and total computer-guided surgery is achieved by Pilot-Drill Guided Surgery, which can combine the advantages of fully guided and free-hand approaches. The Pilot Drill Template implantology is a compromise that combines the benefits of fully guided and traditional surgery while also eliminating their limitations.

Published: November 2024

Introduction The global increase in the older adult population has led to a higher demand for healthcare services, as greater longevity is associated with a rise in the prevalence of chronic conditions like hypertension (HTN). Geographic barriers and current limitations in healthcare services pose significant challenges to access, especially for older adults. Various national and international organizations advocate that telenursing should be widely available to mitigate these challenges by enhancing care delivery, improving proximity to nursing services, and achieving better health outcomes. Objective To map the available evidence on the contribution of telenursing to the prevention and management of cardiovascular risk in older adults with HTN. Methods Following the Joanna Briggs Institute methodology, we conducted the scoping review and used the PRISMA-ScR checklist as a complementary guide. We searched the databases MEDLINE, CINAHL, Open Access Scientific Repository, and Google Scholar for articles and documents up to May 2023, with no temporal filter. Results Seven studies met the inclusion criteria. Six major dimensions characterize the potential of telenursing in older adults with HTN: cardiovascular risk prevention and management, self-management of hypertension, improved quality of life, therapeutic adherence, prevention of clinical inertia, and monitoring of adverse events. Conclusion Telenursing contributes to the prevention and management of cardiovascular risk and fosters a partnership relationship with older adults, supporting self-management of their health and promoting self-care.

The lithological and structural composition of the Ikara North-Central Basement Complex in Nigeria is investigated.
Detailed field and petrographic analyses were carried out to identify the rock types of the area.
The geological map of the area is updated.

Full Abstract
The lithological and structural architecture to unravel the compositions and tectonic evolution of the Nigerian Basement Complex has not been fully documented by geoscientists.  As such, this research aimed to investigate the lithological and structural characteristics of the Ikara North-Central Basement Complex.  Detailed petrographic and field analysis reveals the prevalence of gneiss and granite lithologies characterized by significant structural features such as fractures, folds, and foliations.  These findings offer new understandings of the tectonic evolution of the region.  The study area mapped is the Ikara Sheet 103 Federal Survey Topographic Sheet to a scale of 1:100,000.  The major lithological units underlying the study area are gneisses and granites.  However, these major rock types have varieties, namely migmatitic gneiss, granite gneiss, migmatitic (augen) gneiss, porphyroblastic gneiss, medium to coarse-grained granites, and porphyritic granites.  These rock types were intruded by quartzites, pegmatitic dykes, quartz, and aplite veins.  Rock samples were observed and studied based on their mineralogical composition, color, and texture.  The results of the petrographic analysis showed that the rocks are mainly composed of quartz, plagioclase feldspars, alkali feldspars, mica (biotite and muscovite), hornblende, garnet, and accessory minerals like zircon and magnetite.  Geological structures were also observed during the field study, namely fractures (joints and fractures), foliations, lineations, veins, dykes, and various landforms.  Photomicrographs from thin section analyses revealed micro-structures like myrmekites, micro-folds, and micro-fractures were also observed.  Mineralization such as amethyst and cassiterite were hosted by quartz veins and pegmatites in porphyritic granites, respectively.  A litho-structural map was produced, exhibiting the lithological units and regional structures cross-cutting the area of research.

The results revealed that the water bearing aquifers in the study area are fractured basement layers at varying depths between 15 and 105 meters.
This research provided a robust framework for groundwater exploration in arid and geologically complex terrains.

Full Abstract
The area of study is currently facing an acute water shortage due to the dominant lithological framework that underlies the region and its fragile climate condition.  As such, this study aimed at unearthing the groundwater potential of the area using a combined three geoelectrical techniques.  Techniques such as Electrical Resistivity Tomography (ERT), Natural Electric Field (NEF) method, and Vertical Electrical Sounding (VES) were employed in the delineation of the groundwater potential of the area.  Using an ABEM SAS-4000 Resistivity meter and a PQWT-TC150 water-detector equipment, respectively.  Wennar array was employed for the conduct of ERT while Schlumberger configuration was used for VES data collection.  The measured apparent resistivity value was inputted into RES2DIV software and subjected to an inversion process to generate the resistivity structural image of the subsurface.  However, IP2WIN software was used for the VES data interpretation.  The result of the ERT method revealed two to three geoelectrical resistivity layers: an overburdened layer of topsoil/laterite with resistivity values ranging from 6.86 Ωm to 1095 Ωm and thicknesses of 1-13 meters, a weathered/fractured basement layer, interpreted as the aquifer unit, with resistivity values between 28.7 Ωm and 345 Ωm, and thicknesses ranging from 6 - 30 meters; and a fresh/slightly fractured basement layer with resistivity values from 367 Ωm to 6899 Ωm. NEF method revealed the thickness and depth of the aquiferous layer across the six profile lines to range between 15-60m, 30-90m, 15-85m, 20-80m, 45-105m, and 20-40m respectively, with points on profile five (5) identified as the most promising site with regards to groundwater development.  VES result identifies weathered and fractured layers as the major aquiferous units with resistivity values ranging from 9.965 Ωm to 9651 Ωm and 21.7 Ωm to 859 Ωm respectively with fracture thickness reaching up to 60m in some instances.  The result goes in line with the outcome of both NRF and ERT techniques.  The geological interference of this lithology on groundwater exploration reveals both the weathered overburden and fractured basement as aquiferous units in the study area.  The study identified several promising aquiferous zones at depths ranging from 15 to 105 meters, with fractured basement layers serving as primary reservoirs for groundwater development.
PENTINGNYA PERAN AKTIF PEMUDA SEBAGAI TULANG PUNGGUNG GEREJA DALAM PELAYANAN DI JEMAAT GKI SYALOOM KLAMALU

Berdasarkan hasil penelitian diperoleh bahwa pelayanan peribadatan kaum muda di Jemaat GKI Syaloom Klamalu cukup baik namun, kurangnya keaktifan pemuda yang membuat pelayanan persekutuan pemuda menjadi turun naik. Yang menjadi masalah dalam jemaat ini adalah kurangnya peran aktif pemuda didalam pelayanan persekutuan pemuda dan didalam gereja, sehingga persekutuan pemuda belum sepenunhya berjalan dengan baik. Pemudalah yang akan menjadi tulang punggung gereja bagi masa depan dan untuk memajukan pelayanan dalam jemaat ini. untuk itu perlunya peran pemuda untuk selalu aktif dalam pelayanan maupun kegiatan dalam persekutuan. Banyak sekali alasan dari anak-anak muda yang membuat mereka belum mau bergabung dalam pelayanan persekutuan pemuda. Untuk memajukan pelayanan dalam persekutuan pemuda perlu adanya kekompakkan dan keterbukaan sesama anggota muda, karena kekompakan dan keterbukaan itu yang justru membuat para pemuda merasa dihargai satu sama lain. Selain itu juga komunikasi yang penting dalam persekutuan, dengan adanya komunikasi yang baik membuat anak-anak muda dapat membangun kepercayaan sesama pemuda, dan yang lebih penting juga yaitu dorongan dan juga motivasi dari badan pengurus sehingga para pemuda pun menjadi semangat untuk selalu aktif dalam persekutuan pemuda dan juga didalam gereja. Program-program dalam persekutuan juga dapat mendukung daya tarik pemuda untuk bergabung, maka dari itu program-program yang sudah ada dalam persekutuan harus dijalankan dengan baik, sehingga dengan adanya program yang baik membuat para pemuda menjadi semangat dalam melayani. Dengan kesemuanya itu maka para pemuda akan kembali untuk bergabung dalam persekutuan untuk melayani dan terus memuliakan namaTuhan

Specific learning disorder impairs the brain's ability to process information, affecting around 30-40% of students. These disorders represent 35-45% of mental health visits and 35% of visits to pediatricians. In 2018, Presidente Prudente/SP launched the Specialized Pedagogical Support Program (PAPE) to offer support to students with learning difficulties in the Municipal Network. The study, including 136 students evaluated by MTA-SNAP IV, revealed that ADHD and ODD are common in the school age group, especially in elementary school and more frequent among boys, with inattention being the main characteristic. The research highlighted the effectiveness of the questionnaire in improving intervention and support methods, improving students' quality of life and academic performance. Greater involvement of the Municipal Health Department is recommended to enhance children's care and learning, preventing future problems such as school dropout and difficulties in adult life.
Reconstructing Ancient Korean History
Authors: Xu Stella
Published: November 2024

This book examines the contested re-readings of “Korea” in early Chinese historical records and their influence on the formation of Korean-ness in later periods. The earliest written records on “Koreans” are found in Chinese documents produced during the Han dynasty, from the third century BCE to the third century CE. Since then, these early Chinese records have been used as primary sources for writing early Korean history in Korea, China, and Japan. This study analyzes the various reinterpretations and utilizations of these early records that became more diverse by the late nineteenth century, when the reconstruction of ancient history became a crucial part of the formation of Korean national consciousness. Korea’s modern historiography was complicated by a thirty-five year colonial experience (1910–1945) under Japan. During this period, Japanese colonial scholars attempted to depict Korean history as stagnant, heteronymous, and replete with factional strife, while Korean nationalist historians strove to construct an indigenous Korean nation in order to mobilize Koreans’ national consciousness and recover political sovereignty. While focused on Korea and Northeast Asia, the links between historiography and political ideology investigated in this study are pertinent to historians in general.
The Environmental Crisis and Art
Authors: Räpple Eva Maria
Published: November 2024

Climate change is a defining issue of our time for which the immediate as well as potential future scope causes enormous impediments to human understanding and comprehension. It is argued here that humans ought to make wise use of their capacity of thinking, language, and communication in working on the task of responsible action. Required is nothing less than moving out of “thoughtlessness”, an unresponsiveness and ignorance in particular towards certain environmental problems. As human beings, we are a species on this planet that is uniquely capable to think and foresee potential consequences and hold power to induce change on our actions. It is up to human beings to confront challenges such as climate change, to consider what has been critically assessed in thought and reflect on potential responses. Crucial in this dialog is the ability to take the standpoint of the other –– including that of species as well as ecosystems –– in human imagination. It also means to develop a sensibility for the other in making sense of the world that today is largely shaped by humans. Throughout history, narratives, stories, images, artistic expressions have all played a key role for imaginative ventures that allow the mind to imagine the past, present, and the future. Language and communication can serve comprehension of an issue like climate change and provide a path in developing responsible responses to abstract problems of complex global future dimensions.
Women's Poetry and Poetics in Late Imperial China
Authors: Yang Haihong
Published: November 2024

This literary study examines women-authored poetry and poetic criticism in late imperial China. It provides close readings of original texts to explore the poetic forms and devices women poets employed, to place their work into the context of the wider literary history of the period, and to analyze how they asserted their own agency to negotiate their literary, social, and political concerns. The author also investigates the interactions between women’s poetic creations and existing male scholars' discourses and probes how these interactions generated innovative self-identities and renovations in poetic forms and aesthetics.

Published: November 2024

Trade Unions and the Age of Information and Communication Technologies in Kenya provides a comprehensive description of the use of ICTs within the trade union movement in Kenya. In this book, Professor Eric Otenyo explores the intersection between new technologies and union as key stakeholders in national governance and development. The dearth of research on how trade unions can play a part in the new economy continues to undermine the effective use of ICTs in development. This book brings to light the challenges that unions face while navigating the new economy and netstate characterized by a proliferation of ICTs and globalization.
Football Development Index
Authors: Vorobyev Anatoly , Solntsev Ilya , Osokin Nikita
Published: November 2024

This book provides a systematic overview of football development from a scientific perspective. The proposed multidimensional framework of assessing the concept of sports development (with a deliberate emphasis on association football) goes beyond the conventional medal tally counts and win percentages. The conceptual foundation of the Football Development Index (FDI) revolves around the understanding that football development grasps all athletic proficiency levels from grassroots to elite, and includes all football stakeholders. The proposed composite indicator of football development highlights three key dimensions: on-pitch performance, popularity, and development environment. The book provides both a conceptual discussion on football development as well as an overview of the various techniques used for constructing composite indicators. The practical implications of a multidimensional index on football development cover a vast array of fundamental sports economics and management issues such as performance measurement and management, fairness of funding allocation, sports development policy, stakeholder relations, and many others.

While providing concrete guidelines and recommendations, this book also raises some fundamental issues, such as whether socio-economic determinants can affect a nation's sporting performance. Results turn out to be inconclusive, but going further with this notion, the correlations between socio-economic development levels and football development seem to produce more insightful findings, which shed light on more questions than the book has the ability to answer.

The findings of this research may be adopted by FIFA and continental and national federations to objectify decision-making regarding development programs and activities. This book embodies a systematic assessment approach, which can be adapted to fit the needs of any football governing body and which provides an opportunity to benchmark the best global football development practices. The research also contributes to the theoretic development of performance measurement systems in sports and to the widely discussed issue of direct and indirect determinants of football development.
