Published: September 2024

Aim

This study aims too describe typical ocular component growth patterns in healthy Saudi children.

Background

Prior literature has explored ocular growth patterns in various populations, but there is a gap in understanding these patterns in Saudi Arabia.

Objectives

To establish normative values for ocular biometric parameters and understand correlations between age and ocular development.

Methods

This cross-sectional study involved 141 children aged 3–17 years. The participants were examined at the eye clinic at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, between 2018 and 2023. Every participant underwent a comprehensive ophthalmological assessment, including ocular biometric data [axial length (AXL), corneal curvature, and anterior chamber depth (ACD)].

Results

The mean age of participants was 9.03 ± 3.5 years. The AXL and ACD were 22.49 ± 1.1 mm and 3.34 ± 0.3 mm, respectively. As expected, there was a significant myopic shift with increasing age (p < 0.030). Both the ACD and AXL grew deeper and longer as the children grew older (r = 0.595, p < 0.001 and r = 0.559, p < 0.001, respectively), but corneal curvatures and corneal astigmatism remained constant. AXL values were significantly longer in boys (p = 0.019), but corneal curvatures (K1 and K2) were significantly steeper in girls (p = 0.007 and <0.001, respectively).

Conclusion

This study presents a comprehensive pediatric normative database of ocular biometric parameters for healthy Saudi children. These data will serve as a foundation for tracking the development of refractive errors and may be used as normative values for the evaluation of eye growth in children from the Middle East.

Authors: Zhao Xiaobo , Hao Ronghua , Bai Xuefei
Published: September 2024

Background:

In order to realize seamless indoor and outdoor positioning, the positioning
results of multiple positioning methods are taken into consideration, and a seamless indoor
and outdoor positioning method that ignores the differences in indoor and outdoor environments
is required now.

Objective:

The implementation of Pseudo satellite/GNSS combined indoor and outdoor fusion
positioning for seamless indoor and outdoor environment positioning.

Results:

This algorithm achieves a fixed ambiguity pseudo satellite/GNSS accuracy of better
than 0.15 meters in low-density buildings where there are more than 7 GNSS satellites. When
there are fewer than 4 GNSS satellites and the positions is severely obstructed, GNSS alone
cannot realize the position, but with the support of pseudo satellites, the accuracy of position
can be better than 0.3m. Even without GNSS and only 4 pseudo satellites, the accuracy of position
can still be better than 0.5 m.

Methods:

An adaptive federated filter is needed for this environment, which can dynamically
adjust the information allocation parameters and measurement noise of the sub-filters in the federated
filters based on positioning data. It adopts multi-sensor fusion filter to design a seamless
indoor and outdoor positioning method. Different positioning data is fused through federated
filtering, ultimately seamless indoor and outdoor positioning is realized.

Conclusion:

The relevant experimental results indicate that the method proposed can be used
for practical applications of indoor and outdoor fusion positioning

Abstract                (Title: Creative Process of  Raja Aisyah Sulaiman, Feminist  Women's Literature in Melayu Transision Era). Raja Aisyah bint Raja Sulaiman Ibni Ali Haji or better known as Ayesha Sulaiman was one of the female writers in the Malay literary tradition of the Transitional period. As one of the literary grandchildren of Raja Ali Haji, his life is surrounded by a tradition of good literature. However, his name is unknown in the history of Malay literature. By using the perspective of ginikririk feminist literature, this study examines the creative process of Ayesha Sulaiman, especially in writing one of his works entitled Syair Khadamuddin. The results showed that Syair Khadamuddin was written Aisha Sulaiman to describe his life as a woman in Riau Lingga Malay Kingdom to continue with the sad story of a wife who experienced an inner struggle because of her attitude and outlook on single loyalty to her husband, longing for the abandoned homeland and views on family life and nationhood. The presence of Aisha Sulaiman's work in the transitional period from the 19th century to the 20th century, became a sign of a rebellion against patriarchal domination in Indonesia's local literary history which bound women.Keywords: feminist writers, Malay literature, transitions, ginokritik, poetry

Feasibility, usability, and effects of the leisure-based cognitive training using a fully immersive virtual reality system in older adults: Pilot single-arm pre-post study (Preprint)
Authors: Chuang I-Ching , Huang Xiao-Ting , Chen I-Chen , Wu Yih-Ru , Wu Ching-Yi
Published: September 2024

BACKGROUND

Cognitive training has been shown to improve cognitive function in older adults, with the inclusion of leisure activities such as gardening potentially enhancing both its effectiveness and enjoyment. Although fully immersive virtual reality (VR) training has demonstrated positive outcomes, research integrating leisure activities with VR for older adults remains sparse. We developed a VR system incorporating gardening to enhance cognitive function in community-dwelling older adults.

OBJECTIVE

This study aimed to assess the feasibility, usability, and preliminary effectiveness of leisure-based VR cognitive training for community-dwelling older adults.

METHODS

The fully immersive VR system used a head-mounted display for leisure-based cognitive training, featuring simulated gardening tasks (planting, fertilizing, harvesting) to enhance cognitive function. Participants trained twice weekly for 1 hour over 8 weeks. Feasibility and usability were assessed by older adults and professionals. Outcome measures were the Montreal Cognitive Assessment (MoCA), Digit Symbol Substitution Test (DSST), Word List subtests and Spatial Span subtests of the Wechsler Memory Scale (WMS-WL and WMS-SS), and the Stroop Color and Word Test (SCWT), with assessments conducted before and after training.

RESULTS

The study recruited 41 elderly participants, all of whom completed the 16 VR training sessions with 100% attendance. Acceptance of the VR experience (PU, PE, UE, ITU) was above average, with a usability score of 68, rated "average." After training, significant improvements were seen in MoCA (p= 0.004), DSST (p= 0.049), WMS-WL (p< 0.001), and SCWT (p= 0.002), but no significant change was found for WMS-SS (p= 0.29).

CONCLUSIONS

Our findings show that the leisure-based VR cognitive training system is feasible, usable, and effective in enhancing cognitive function in community-dwelling older adults. Future studies should include control groups to confirm these results.

Between Tongues: The Battle for Linguistic Equity in Tanzanian Schools – An Autoethnographic Study
Authors: Massawe Scholastika
Published: September 2024

This autoethnographic study delves into the personal experiences of both a student and a teacher navigating the dual-language educational framework of Swahili and English in Tanzania. The research investigates how these individual narratives enhance our understanding of the broader impacts of language policies. By integrating personal reflections with theoretical analysis and a comprehensive literature review, the study explores the profound effects of these policies on both students and teachers. The findings reveal significant advantages of using Swahili, the native language for the majority of learners, in fostering not only academic success but also emotional and psychological well-being. Conversely, the use of English as a medium of instruction is shown to exacerbate educational disparities and hinder the emotional health of students. Based on these insights, the study advocates for substantial revisions to the current language policies, suggesting a shift towards prioritizing Swahili to better meet the needs of the majority, thus promoting greater educational equity and inclusivity.
Advancement of Domestic Mobile Agricultural Machinery Powered by Electric Traction
Authors: Tsench Yu. S. , Sharov V. V.
Published: September 2024

With the implementation of the GOELRO plan in the late 1920s and early 1930s, efforts were made to extend the use of electricity to agricultural fieldwork through the development of specialized machines and mechanisms. Numerous inventors, engineers, and scientists focused on finding ways to electrify energy-intensive agricultural operations. As a result, various designs of electric plows and electric tractors emerged. (Research purpose) The paper aims to analyze the development of electric tractors in the USSR during the period from 1930 to 1956. (Materials and methods) The study employs a chronological research method, examining scientific and technical publications, along with other sources, that address the manufacturing and testing of electric tractors. Conclusions were drawn through the analysis and synthesis of the reviewed materials. (Results and discussion) The initial phase of electrifying soil cultivation operations was marked by the development of plows powered by electric winches. In the early 1930s, tractors emerged with electric motors replacing traditional heat (internal combustion) engines. Advancements in electric tractor design led to the creation of tracked models such as the HTZ-15 (Kharkov) and ET-5-ENIN-VIESh (Moscow), which underwent extensive economic testing. The results indicated that the use of electric tractors in fi eld crop farming was unsuitable due to both technical and economic factors. (Conclusions) Between 1930 and 1956, at least 15 types of wheeled and tracked electric tractors were developed in the Soviet Union. Testing these models revealed both the advantages and drawbacks of electrified traction equipment. Despite their eff orts, mid-twentieth-century engineers were unable to resolve the technical challenges associated with the implementation of electric tractors, leading to the termination of the project in 1956.

Published: September 2024

The paper highlights the benefits of using seed tape planting technology, which include reduced seeding rate, optimized application of fertilizers and chemicals, and the ability to quickly switch between different crops or seed varieties. This technology shows positive effects on nearly all agricultural crops. (Research purpose) The study aims to explore the history of the emergence and application of seed tapes (seed ropes) for planting, detailing their design features and production technologies. (Materials and methods) The research employs a historical-analytical method, examining scientific publications, patent databases, such as Espacenet and the Federal Institute of Industrial Property, as well as photographic materials. (Results and discussion) The paper provides information on the origin of the first seed carriers which were flexible holding strips of paper or similar material that enclosed seeds. It covers the development and advancement of this planting technology, highlighting the use of currently most popular seed tapes. Universal or combined tapes and twisted seed strands can serve as carriers of fertilizers, pesticides, herbicides, and other substances in various combinations, in addition to seeds themselves. The paper reviews inventions related to the types and manufacturing methods of seed tapes and seed ropes proposed in different countries from 1898 to 2023. (Conclusions) The differences between seed tapes and seed ropes primarily lie in the mechanization of their production. The seed carrier can be made from various biodegradable materials, such as paper, plant fiber cloth, polymers or others. When manufacturing these tapes, it is necessary to minimize seed damage. The present research results in the formulation of principles for selecting biodegradable polymeric materials for seed tape planting technology. These principles include high diffusion rates, swelling properties, and maintaining a balance between tape biodegradation and biochemical reactions in plant cells.

Published: September 2024

The paper highlights that integrating distributed power generation facilities into power supply systems for rural consumer with voltage up to 1000 volts leads to the challenges in managing the confguration of the associated electrical grids. To manage the configuration of power supply systems for rural consumers with voltage up to 1000 volts, it is proposed to use multicontact switching systems. However, there are currently no established methods or criteria for determining optimal locations for multi-contact switching systems in power supply systems for rural consumers with voltage up to 1000 volts that include distributed generation facilities. (Research purpose) The study aims to develop a method for determining the optimal placement of multicontact switching systems in rural electrical grids with voltage up to 1000 volts that include distributed generation facilities. (Materials and methods) An analysis is conducted to evaluate the implementation of configuration management devices in the examined power supply systems. The study explores the impact of installing multi-contact switching systems and identifies the main types of damage caused by power supply interruptions for agricultural consumers. Additionally, a method was developed to determine the optimal placement of multi-contact switching systems. (Results and discussion) The paper demonstrates the practical application of the developed methodology through a case study on the reconstruction of a rural electrical grid with distributed generation facilities. Among the proposed options, the optimal location for placing multi-contact switching systems was selected. (Conclusions) The installation of multi-contact switching systems helps mitigate damage from power interruptions for rural consumers. The choice of optimal locations for multi-contact switching systems is influenced by various factors, any of which can be decisive, depending on the specific circumstances. The developed methodology enables a comprehensive evaluation of all relevant factors, allowing for the most appropriate choice to maximize the overall efficiency of the power supply system. Using the proposed methodology to determine the optimal location for multi-contact switching systems results in a 55 percents damage reduction in the rural electrical grid caused by power outages.

Published: September 2024

This article aims to verify the strategies used in the documentary ‘Smokescreen’, released by the production company Brasil Paralelo (2020). We sought to identify which aspects are mobilized in this type of production, with characteristics of traditional journalism. The theoretical matrix used comes from Perelman & Olbrechts-Tyteca (2005), who defend the authority argument as a strategy for supporting arguments in discourse. In the film analyzed, we observed that professional and academic credentials, in addition to the origin of the sources, are the resources of greatest value in this activation. The use of the authority argument gives legitimacy to revisionist versions of the climate crisis, indigenous causes and political problems in Brazil. The video incisively defends agribusiness as a synonym for economic progress and denounces vested interests in the work of NGOs dedicated to the environment, exposing a disconnected order of scattered and superficial facts when dealing with the whole.

Limited land area and cross-sectional of steel profiles make planners have to choose the type of structure that is effective and efficient. Variations in the type of subgrade during an earthquake will give a different response to the structure which ultimately determines the dimensions of the structural elements. This study aims to determine the behavior of gable frame structures with variations in spans, number of portals and site classes. Modeling is done with variations of portal spans of 8, 24, and 30 m. The second variation is the number of portals, namely 1, 2 and 3 portals with a span of 24 m. The 3rd variation is in the form of class sites (hard, medium and soft soil) with a span of 2x24 m. The behavior analyzed is the base shear force, roof displacement and the demand to capacity ratio of the column and rafter. The 18 m span uses the IWF profile 200x150x6x9, the 24 m span uses the 300x150x6.5x9 profile and the 30 m span uses the 350x175x9x12 profile. The ratio of demand to capacity respectively for the column structure is 0.1909; 0.2560 and 0.2494 for spans of 18, 24 and 30 m. In the variation of the number of portals, it was found that designs 1, 2 and 3 had a Demand-Capacity Ratio value of 0.687 for rafters; 0.639 and 0.638 while in the column obtained respectively 0.713; 0.873 and 0.915. The design of the number of portals 1, 2 and 3 has a maximum deviation value of 68,699; 78,364 and 82,462 mm. In terms of serviceability, it shows a larger deviation and increases its capacity in resisting bending and compression. The results of the analysis of the 3 models with variations in soil sites show that hard soil, medium soil and soft soil have base shear force values of 205,163 kN, 337,883 kN, and 269,899 kN and the maximum deviation at the top of the building is 61,981 mm, 102,079 mm, and 37,642 mm.

Introduction: Meconium Stained Amniotic Fluid (MSAF) is a frequent finding during deliveries and is a cause for perinatal morbidity and mortality. Meconium Aspiration Syndrome (MAS) in neonates is an association in these deliveries with some infants requiring mechanical ventilation. This study was done with the aim of finding the risk factors for MSAF and its perinatal outcome. Methods: This was a hospital based, cross-sectional study. All the inborn babies delivered with MSAF were included in the study. Antenatal risk factors and perinatal outcomes like mode of delivery, Apgar score, NICU admission and neonatal morbidities mainly MAS were noted. Results: MSAF was seen in 202 (13.6%) neonates out of which 30 (15%)developed MAS. Antenatal risk factors were present in 97 (48%) cases. Mode of delivery was caesarean section in 78 (39%) and instrumental in 25 (13%) cases. Twenty three percent of the neonates required resuscitation at birth while 34% required respiratory support. Morbidities observed were meconium aspiration, pneumonia, septicaemia, perinatal asphyxia, shock, meconium gastritis and persistent pulmonary hypertension. Neonatal mortality amongst all neonates with meconium was 1.5%.Conclusion: Meconium stained amniotic fluid leading to aspiration is a significant cause of neonatal mortality and morbidity. Most of the risk factors for MAS are preventable.

Published: September 2024

Introduction: Best disease or vitelliform macular dystrophy is a rare autosomal dominant disorder with bilateral presentation characterized by subretinal accumulation of yellowish material in the macular area. Macular findings range from a small yellow spot, multiple vitelliform or atrophic lesions to a chorio-retinal scar. Case report: A 35 years male presented to our outpatient department with chief complaint of blurring of vision of both eyes for the past three months. His visual acuity was 6/12 in both right and left eyes. On slit-lamp bio-examination anterior segments of both eyes were normal. On fundus examination, both eyes revealed a single, circular, yellow-opaque egg yolk-like macular lesion with no other abnormalities. Optical coherence tomography of both eyes revealed deposits of homogenous hyper- reflective material beneath retinal pigment epithelium at fovea. Fundus fluorescence angiography showed blocked fluorescence at the site of vitelliform lesion of both eyes. Conclusion: Best vitelliform macular dystrophy is a rare genetic disorder with incomplete penetrance. Optical coherence tomography and fundus fluorescence angiography support the diagnosis.

Safe Motherhood Program (SMP) has been one of the successful ongoing maternal health programs in Nepal. It is the major reason for Nepal being able to reduce its Maternal Mortality Ratio (MMR) significantly falling from 539 to 281 deaths per 100000 live births over the decades. SMP has nine components out of which three components mainly deal with pregnancy and puerperium; birth preparedness plan, rural ultrasound program and the â€œAama and New born Programâ€. The latter one is one of the key components of SMP which includes incentives, free delivery services and free sick newborn care. Financial incentives are provided for transport and completion of four antenatal visits, and for health care workers attending deliveries. However, with the corona virus disease (COVID-19) pandemic, this program might not be enough to ascertain a safe motherhood for Nepalese women. This program aims to reduce the three delays leading to maternal morbidity and mortality namely, delay in reaching care, seeking care and receiving care. But with a nationwide lockdown, the chances of these delays have increased even more.
Limitations of COVID-19 Fever Clinic as the First Point of Contact: Are We Relying Too Much? An Experience from a Tertiary Center
Authors: Shrestha Deepak
Published: September 2024

In Nepal, after the first case was diagnosed with Corona Virus Disease -19 (COVID -19) in a 32-year-old returnee from Wuhan, China on 13 January 2020, it took more than four months to reach a figure of 500 infected cases. Seventy of them have already recovered and returned home. However, the curve has been taking a steeper slope after the first 50 cases were documented. With the first mortality from COVID-19 confirmed on 16thMay, 2020, the fact that this pandemic is tightening its grip in the country is more evident now. And witheach passing day, more cases are being diagnosed. In such a situation, strategies of screening the infected/suspects are of paramount importance and those already in place should be strengthened. On March 19, the Nepal Medical Council asked all hospitals, both private and public, with over 100 beds to operate a separate fever clinics and postpone elective surgeries to conserve resources for an outbreak. Such fever clinicsaim at separating and filtering out the suspected/ diagnosed COVID-19 patients. Arguably started firstin Kathmandu Medical College, fever clinics now have been established and run in almost every largehealth care centers. United Nations International Childrenâ€™s Emergency Fund (UNICEF) has been pivotal in supporting some of these centers. Rising up to the task, Lumbini Medical College and Teaching Hospital started its fever clinic from 22 March 2020 in a separate makeshift place which later moved to a more organized structure. The fever clinic is set up in a separate area in order to keep off suspected patients from the main hospital.

Matrix transformation and application of Hausdorff measure of non-compactness on newly defined Fibo-Pascal sequence spaces
Authors: Dağlı Muhammet , Yaying Taja
Published: September 2024

In this article, we introduce Fibo-Pascal sequence spaces PFc and PF0 by
utilizing a newly defined Fibo-Pascal matrix PF. It is proved that PFc and
PF0 are BK-spaces that are linearly isomorphic to c and c0, respectively.
Furthermore, the Schauder basis and ?-, ?-, ?-duals of both the spaces are
computed, and certain classes of matrix mappings are characterized. The
final section is devoted to characterize compact operator on the space PF0
via Hausdorff measure of non-compactness (shortly, HMNC).
On the curvatures of timelike circular surfaces in Lorentz-Minkowski space
Authors: Li Jing , Yang Zhichao , Li Yanlin , Abdel-Baky R.A. , Saad Khalifa
Published: September 2024

In this paper, using the classical methods of differential geometry,
wedefine invariants of timelike circular surfaces in Lorentz-Minkowski space
R3 1, called curvature functions, and show kinematic meaning of these
invariants. Then we discuss the properties of these invariants and give a
kind of classification of the surfaces with the theories of these
invariants. Besides, to demonstrate our theoretical results some
computational examples are given and plotted.
On bishop frame of a partially null curve in Minkowski space-time E41
Authors: Djordjevic Jelena , Nesovic Emilija
Published: September 2024

In this paper, we introduce Bishop frame of a partially null curve ? in
Minkowski space-time E41 . We prove that such curve has three Bishop frames
determined by the particular solutions of the third order non-linear
differential equation. We show that the Frenet frame of ? can be obtained by
rotating the Bishop frame that corresponds to the particular solution ?(s) =
R ?1(s) ds of the mentioned differential equation. As an application, we
obtain the parametrization of a lightlike hypersurface and focal surface
with base curve ? in terms of its Bishop frame. Finally, we prove that a
lightlike focal surface along a partially null helix has no critical value
set.
Numerical simulation of the casting process of an AZ91D magnesium alloy under a rotating-pulsed combined electromagnetic field

Using an AZ91D magnesium alloy as the research object, a three-dimensional (3D) numerical model was created and simulated using simulation analysis software. The effects of a rotating electromagnetic field (REMF), a pulsed electromagnetic field (PEMF) and a rotating pulsed electromagnetic field (R-PEMF) on the magnetic field and the flow field of a metal melt were investigated. The simulation results show that during the REMF treatment a rotational force is generated on the cross-section of the melt, and the PEMF exerts a magnetic pressure on the cross-section of the melt. Under the combined effect of these two forces, the Lorentz force increases parallel to the melt axis, and a secondary flow directed towards the core of the melt is generated, which contributes to the homogenization of the melt. By analyzing the solidification structure and elemental distribution of the metal, R-PEMF was shown to effectively improve the solidification structure and macrosegregation of Al in AZ91D magnesium alloy.
Pursuing the national interest of Serbia through interpresidentialism of the Open Balkan Initiative
Authors: Hrnjaz Milos , Milosevic Aleksandar
Published: September 2024

This article attempts to answer the question of the relationship between Serbia?s perceived national interests and the Open Balkan Initiative. It starts with a theoretical framework and concepts of national interests and regional integrations of the Western Balkans. It then proceeds with a concise history of these integrations and their relationship with the EU accession process of Balkan countries. The article?s central part focuses on the economic, institutional, and legal aspects of the Open Balkan Initiative and how the perceived national interests of Serbia determine these aspects. The main conclusions are that political leaders of Serbia, Albania, and North Macedonia have used interpresidentialism as a form of regional integration, deliberately avoiding institutionalisation, and decided to almost exclusively use non-binding instruments of international law in the Open Balkan Initiative. Additionally, the economic results of the initiative are limited so far.
Maritime Terrorism V. Piracy at Sea: Prevention of Maritime Security Threats and the Responsibility of States to Prevent in the Perspective of International Law
Authors: Kultsum Fatia
Published: September 2024

The sea is used as an alternative spatial medium to realize the interests and goals of each country. Nearly 80% of the world's cargo is transported by sea with more than 112,000 ships manned by more than 1.5 million seafarers. However, the sea is also a vulnerable area to violence, including maritime terrorism and piracy at sea which can threaten maritime security and the national economy if there is no special handling. Several conventions govern the international legal regime, including UNCLOS 1982, the SUA Convention, and the ISPS Code. Under international law, coastal states are responsible and obliged to prevent acts of terrorism by taking necessary measures to enhance their maritime security.
Sem Shibboleths
Authors: Salom Julio Souto
Published: September 2024

observamos o estudo do idioma yorùbá por grupos afro-religiosos no Brasil experimentando o conceito sociolinguístico shibboleth, para cogitar a hipótese da imaginação de uma comunidade nacional transatlântica. Apresentamos as aulas de yorùbá do mestre Cica de Òyó no terreiro da Mãe Sandra de Xapanã em Alvorada (RS, Brasil). O idioma se aprende desde a cosmopolítica afro-brasileira, estabelecendo relações de cortesia e diplomacia que valorizam a diferença, para enriquecer os rituais litúrgicos e a memória comunitária, como habilidade conectiva com o heterogêneo e etimologia contra-colonial. O estudo do yorùbá não busca a homogeneização normativa, o que contesta a tese antropológica da eclesificação do culto aos orixás e da reafricanização como concorrência pela pureza originária. Sem shibboleths, o estudo do idioma não institui normas visando uma nação yorùbá transatlântica, mas ativa agenciamentos entre nações, bacias, casas, ancestrais, deuses e aparelhos, valorizando a multiplicidade como patrimônio da matriz afro-brasileira.
Minoritização, religião pública e populismo religioso no Brasil
Authors: Burity Joanildo
Published: September 2024

Este artigo discute a trajetória da emergência evangélico-pentecostal na política brasileira, a partir de um marco analítico fornecido pelas categorias minoritização, religião pública e populismo, abordando-a em chave diacrônica, desde os anos 1980 até as eleições de 2022. Argumenta-se que a emergência evangélica expressa uma irrupção do político como dimensão instituinte do social, independentemente de seu caráter religioso, e que ela se desdobra em distintos momentos, não previstos ou planejados, de afirmação de uma minoria como parte da definição da identidade nacional (povo nacional) e de paulatina inserção no pacto político vigente na sociedade, levando-a a aspirar a direção moral e política da sociedade, num contexto de crise hegemônica. Esta minoritização implicou na transformação do campo evangélico-pentecostal em religião pública, atravessada pelas dinâmicas e conflitividade sociais amplas, enquanto a credenciou a integrar um novo bloco de poder no intento de fundar um novo povo brasileiro, pós-lulista, pós-democrático, integrado por “cidadãos de bem” de uma “maioria cristã”, em ressonância com outras posições conservadoras empenhadas no enfrentamento da “esquerda”, como inimigo inassimilável.
