Introdução: A reabsorção interna inflamatória resulta da atividade dos odontoclastos nas paredes dentinárias onde a camada de pré dentina foi danificada. Embora não seja claro quais os fatores responsáveis por estes danos, agressões físicas, químicas e infeções bacterianas são causas prováveis. O tratamento de uma reabsorção interna inflamatória sem perfuração radicular apenas requer tratamento endodôntico não cirúrgico. O tratamento de uma reabsorção interna inflamatória comunicante é sempre complexo. Exige uma avaliação detalhada da extensão da lesão através de uma tomografia computorizada de feixe cónico, uma abordagem com microscópio operatório e o uso de biomateriais. Descrição do caso clínico: Paciente feminina, de sessenta anos, foi encaminhada para a consulta de especialidade de endodontia para tratamento de uma reabsorção interna inflamatória associada à raiz distal do dente 46. A paciente reportou história de inchaço e dor associada à região. No momento da consulta a paciente não apresentava queixas. A percussão realizada revelou-se positiva. Estabeleceu-se um diagnóstico de periodontite apical sintomática e dente previamente tratado. Após avaliação da tomografia computacional de feixe cónico, verificou-se a presença de lamina dura associada à raiz mesial e ausência de lâmina dura na região da perfuração radicular. Optou- se pelo tratamento endodôntico não cirúrgico seletivo da raiz distal. O tratamento foi realizado em três consultas com recurso a microscópio operatório. Após desobturação foi possível localizar o canal radicular e iniciar a preparação química e mecânica. O canal radicular apical ao defeito foi obliterado com um cone de gutta percha e procedeu-se a compactação do biomaterial. Após presa do biomaterial, os restos de gutta percha foram removidos e concluiu-se o tratamento endodôntico não cirúrgico. O dente foi reabilitado com uma restauração direta com recobrimento cuspídeo. Ao controlo de seis meses o dente apresentou-se assintomático. Discussão e conclusões: Retrospetivamente não é possível associar uma etiologia exata ao presente caso. O uso de biomateriais, com propriedades bioativas e osteogénicas, encontra-se indicado para a abordagem de reabsorções internas inflamatórias comunicantes. Será necessário mais tempo de controlo para confirmar a completa regeneração óssea. O recurso à tomografia computorizada de feixe cónico e o uso do microscópio operatório garantiram a correta abordagem do caso e eliminação da sintomatologia.

Published: January 2025

The most important factor in both plant development and productivity, which mostly depends on nutrient availability in the soil and environment, is the constituents of soil nutrients. Soil is always losing its nutrients by leaching, surface runoff as well as through harvesting and cultural operations like: pruning. For maintaining the balance of agricultural ecosystem fertilizer application is necessary to improve soil condition and gain better yield. In case of tea industry for maintaining better and uniform production applying fertilizer is a widespread management technique in worldwide. Tea requires a lot of macro and micronutrients for growth because it cannot be grown without the usage of fertilizer and other nutrient supplies. The purpose of this field survey was to ascertain the nutritional condition of tea leaves as well as the signs of nutrient deficiencies in tea plants. In this study, deficiency symptoms of the essential nutrients were found out at different tea estates of Moulvibazar and Sylhet districts as well as photographs were taken. Photographs of the nutrient deficient tea plants were correlated with the established symptoms. The range of total nitrogen, phosphorus, potassium, calcium, magnesium and zinc content in the collected tea leaf samples were 2.95- 5.18%, 0.28- 0.49%, 0.56-1.88%, 0.12-0.49%, 0.07-0.08% and 0.002- 0.004%, respectively.

Published: January 2025

Promoting rooftop farming using suitable grow bag media is of utmost importance in densely populated cities like Lalitpur to sustain the human race. To assess the productivity and other economic characteristics of bell peppers, an experiment was conducted from Feb 2022 to Jun 2022 in different grow bag media on the premises of Vegetable Crop Development Centre, Khumaltar, Lalitpur. The experiment was conducted in Randomized Complete Block Design (RCBD), with four replications and five treatments with growing media: Coco peat: vermicompost (1:1), Soil: sand: FYM (Farmyard Manure) (1:1:1), Soil: Sand: FYM: Vermicompost (1.25:0.75:0.5:0.5), Soil: vermicompost (1:1), and Soil: ash: FYM (1:0.5:1) on the cultivar California Wonder. Growth parameters like plant height (47.865 cm), number of leaves (50.6), number of branches/plant (9.5), and stem diameter, and yield parameters like total fruit weight (1693.93 gm), average fruit weight (84.68 gm), number of fruits (42.75), fruit diameter (6.37 cm), and fruit length (7.22 cm) were observed during the experiment. The media consisting of T3 (Soil: Sand: FYM: Vermicompost (1.25:0.75:0.5:0.5)) proved to be statistically superior over the rest of the combinations for almost all aspects under investigation, whereas comparatively poor performance was observed in Coco peat: vermicompost (1:1) media. This study suggests that the grow bag media of Soil: Sand: FYM: vermicompost (1.25:0.75:0.5:0.5) gave the highest gross return and net return, with the highest B: C ratio (2.08) observed in the grow bag media of Soil: Sand: FYM (1:1:1).

Published: January 2025

Los sistemas humanos, la dinámica de la población y el desarrollo económico requieren un cambio de paradigma considerando pasar de un modelo lineal a uno basado en la economía circular. Este enfoque busca satisfacer las necesidades alimentarias, materiales y energéticas de una población mundial en crecimiento. La economía circular permite integrar sistemas que gestionan de manera integral los recursos, reducen costos y adoptan nuevas tendencias de producción y generación de valor. Según se sabe, existe un vacío del estado del arte de la economía circular en el campo de la agricultura mediante análisis bibliométrico. Considerando su importancia, se logró identificar una brecha significativa en la literatura dentro de esta área. Para ello se realizó un estudio bibliométrico de 57 artículos utilizando programas como VOSviewer, Orange y Bibliometrix. La producción científica analizada va desde el 2007 al 2024, reflejándose un crecimiento en el 2022. Entre los países que más exploran esta temática se encontró a Ecuador y China, referente a la afiliación que más predomina destaca la Universidad de Almería. Además "Desarrollo" y "Sostenible" surgieron como puntos clave de interés. Esta investigación sirve como antecedente para profundizar en los principios que rigen la economía circular y explorar las temáticas que la relacionen con la agricultura; para un enfoque emergente que permita innovar la forma en que se realizan las actividades agrícolas a nivel global, con el objetivo de lograr sistemas agrícolas más resistentes, eficientes y sostenibles a largo plazo.
Assessment of Hydrogen Sulfide Emission during Asteroid Impact in the Black Sea.
Authors: Degterev Andrey Kharitonovich , Kucherik Galina Valentinovna
Published: January 2025

The article considers the current problems of predicting the Earth's collision with asteroids and comets. Mathematical modeling of analyzed process of asteroids falling into oceans and seas is especially complex. Such models are based on solving the classical Euler-Navier-Stokes equations. The relevance of abovementioned problem is also justified by a number of features of the Black Sea basin, including the presence of a large amount of hydrogen sulfide and methane. An estimate of the concentration of hydrogen sulfide in the air during an asteroid fall into the Black Sea was obtained. It is shown that the main emission is associated with expected release of deep waters to the surface in the area of the fall, due to which the concentration of hydrogen sulfide in the surface layer of the atmosphere can reach one gram / cubic meter. In the cloud formed by the steam emission, the concentration of hydrogen sulfide does not exceed 0.04 gram/cubic meter. Based on obtained results of their study, authors come to conclusion that the content of hydrogen sulfide in the steam, and then in resulting cloud, is half the dangerous values at which the evacuation of the population is necessary. The principal difference between an asteroid hitting water and hitting a solid surface is that it does not immediately explode or melt but goes under water. In certain areas of the sea, the fall of an asteroid to the bottom can cause methane emissions, including due to the melting of gas hydrates. In this case, an explosive concentration of the gas-air mixture can be achieved. Perhaps the greatest danger is associated with the impact of the asteroid on the bottom and the subsequent exit of deep waters to the surface.
Upregulation of phosphatase and tensin homolog deleted on chromosome ten inhibits lung cancer cell proliferation by suppressing the oncogene polo-like kinase 1 and inducing autophagy
Authors: Jiang Weizhou , Wang Pei , Huang Limin
Published: January 2025

Objective:

Lung cancer is one of the main causes of cancer-related mortality globally, and it poses considerable therapeutic challenges. Polo-like kinase 1 (PLK1) exhibits upregulation in lung cancer, and PLK1 silencing promotes autophagy in lung cancer cells, which inhibits tumor progression. The phosphatase and tensin homolog deleted on chromosome ten (PTEN) acts as a tumor suppressor gene. This study aimed to investigate whether PTEN regulates autophagy and inhibits lung cancer-cell proliferation by suppressing PLK1.

Material and Methods:

In this study, we evaluated cell proliferation by silencing or overexpressing PLK1 and PTEN in A549 cells through 5-ethynyl-2'-deoxyuridine labeling and cloning experiments. The autophagy levels were detected through transmission electron microscopy, real-time quantitative polymerase chain reaction, and Western blot. Finally, the results of in vitro experiment were further verified using an in vivo xenograft tumor animal model.

Results:

The upregulation of PTEN suppressed PLK1 expression in lung cancer cells and reduced their proliferation rate. In addition, the overexpression of PTEN has been associated with the growth of lung cancer tumors. In parallel, the levels of autophagy of lung cancer cells rose in response to PTEN upregulation in vivo and in vitro.

Conclusion:

This study revealed that PTEN promotes the autophagy of lung cancer cells and inhibits cell proliferation and tumor growth by suppressing PLK1 expression. This finding provides a new strategy for lung cancer treatment by utilizing the autophagy-regulating effect of PTEN to inhibit lung cancer growth by targeting PLK1.

The article presents a literature review that analyzes the occurrence of chronic cicatricial stenosis of the larynx and trachea in childhood and the difficulties of its treatment. Laryngeal and tracheal cicatricial stenosis is one of the most complex and unsolved problems of modern otorhinolaryngology in both children and adults. Despite the variety of methods of conservative and surgical treatment, including endoscopic minimally invasive surgery and open laryngeal and tracheal reconstruction, there is no single algorithm for the management of patients with cicatricial stenosis of the larynx and trachea. Treatment is often long-term and multistage, thus, coordination between pediatric and adult institutions is crucial for timely and qualified medical care.

В статье представлен литературный обзор, в котором проведен анализ возникновения хронического рубцового стеноза гортани и трахеи в детском возрасте и трудностей его терапии. Гортанно-трахеальный рубцовый стеноз является одной из самых сложных и нерешенных задач современной оториноларингологии, касающейся как детей, так и взрослого населения. Несмотря на многообразие методов консервативного и оперативного лечения, включая эндоскопическую малоинвазивную хирургию и открытую гортанно-трахеальную реконструкцию, единого алгоритма ведения пациентов с рубцовым стенозом гортани и трахеи нет. Лечение зачастую длительно и многоэтапно, в связи с чем актуален вопрос преемственности между детскими и взрослыми учреждениями с целью оказания своевременной и квалифицированной медицинской помощи.

Background. One of the most common complications of orthognathic surgery is neurosensory deficit of the trigeminal nerve branches. Various diagnostic methods are used to determine the area of the deficit and the duration of the recovery period. The purpose of this study was to determine the recovery patterns of sensory and pain sensitivity using 3 neurological tests after Le Fort I osteotomy of the maxilla (Le Fort I), bicortical sagittal split osteotomy of the mandible (BSSO) and chin osteotomy (GENIO). Material and methods. The study included 40 patients (14 males and 26 females) aged 18-45 years with skeletal anomalies and was carried out at the Department of Maxillofacial and Plastic Surgery of the A.I. Evdokimov Moscow State Medical University. Surgical interventions included Le Fort I osteotomy of the maxilla (Le Fort I), bicortical sagittal split osteotomy of the mandible (BSSO), and chin osteotomy (GENIO). Results. Patients with neurosensory deficit of the trigeminal nerve branches following Le Fort I osteotomy, BSSO, and chin osteotomy were followed for 12 months. The obtained results are illustrated in graphical form. Conclusion. Patients with neurosensory deficits following Le Fort I osteotomy had the shortest recovery period. Patients following BSSO combined with GENIO osteotomy had the highest incidence of NSD (neurosensory deficit). Despite this, neurosensory deficit can be reversible.

Актуальность. Одно из самых распространенных осложнений у пациентов после ортогнатической хирургии является нейросенсорный дефицит (НСД) ветвей тройничного нерва (ТН).

Pasien yang akan menjalani proses laparotomy akan menerima anestesi guna meringankan rasa nyeri. Efek anestesi yang diberikan kepada pasien dapat memperlambat motilitas gastrointestinal pasca operasi yang menyebabkan kehilangan peristaltik. Peristaltik yang hilang dalam waktu lama akan menghambat pemulihan kondisi pasien dan proses penyembuhan luka. Mengunyah permen karet pasca operasi dapat merangsang motilitas usus melalui refleks vagal sefalik dan dengan meningkatkan produksi hormon gastrointestinal yang bisa mengatasi difungsi motilitas gastrointestinal pasien post-laparotomy. Tujuan penulisan studi kasus ini adalah menggambarkan penerapkan intervensi mengunyah permen karet Xylitol® untuk meningkatkan peristaltik usus pada asuhan keperawatan pasien post-laparamoty. Metode penulisan yang digunakan dalam studi kasus ini berupa metode deskriptif dengan pendekatan studi kasus dengan intervensi utama mengunyah permen karet xylitol. Subyek studi adalah tiga oran pasien post operasi laparotomy dengan general anastesi, telah sadar penuh (2-3 jam setelah operasi), dapat mengunyah permen karet, tidak alergi terhadap permen karet, tidak menggunakan nasogastric tube dan memiliki keluhan mual, belum bisa flatus. Subyek studi diminta mengunyah permen karet Xilytol® sebanyak 4 butir (5,8 mg) selama 10 menit, dilakukan tiap 8 jam dengan cara mengunyah 2 butir selama 5 menit kemudian dibuang dan kemudian dilanjukan 2 butir selanjutnya. Peristaltik usus setiap jam diukur dengan menggunakan stetoskop melalui pemeriksaan auskultasi abdomen. Hasil yang didapatkan peristaltik usus membutuhkan waktu 2 jam untuk kembali setelah mengunyah permen karet dengan rata- rata suara peristaltik usus yang muncul 2 kali permenit. Mengunyah permen karet Xylitol® dapat dijadikan intervensi untuk mengatasi masalah disfungsi motilitas gastrointestinal pada pasien post laparotomy.

Authors: VINCZE Beatrix
Published: January 2025

The study aims to present the current reform and alternative education situation in Hungary. Hungarian reform pedagogy has a long history, and between the two world wars, the reception of European reform trends became a significant part of the pedagogical culture. The New School movement, the Child Study movement and experimental pedagogy became an integral part of Hungarian pedagogy. Reform pedagogical institutions were established mainly in the capital, the most important being Waldorf, Montessori pedagogy, the Family School, the New School, and in the countryside, the most significant were the School of Action and the Garden School (Szeged).
The information sources for the study were the results of research on reform pedagogy and life reform in Hungary, studies about alternative pedagogical schools, and pedagogical websites. The outline and overview analysis cover the conceptual definitions, the historical traditions and the main features of the current situation. The research group of Eötvös University (led by Prof. András Németh), the Jena-Plan working group, has played a prominent role in researching (over 30 years) and promoting the Hungarian reform pedagogical movement.
Identifying Suitable Dam Locations in Al Dinder: Integrating GIS, Remote Sensing, and Hydrological Factors
Authors: Anwer Hossam Aldeen
Published: January 2025

This study evaluates the suitability of dam site locations in the Al Dinder region of Sudan using a GIS-based approach and weighted overlay analysis. Five key criteria were assessed: Stream Order, Slope, Soil Type, Precipitation, and Land Cover. Each criterion was analyzed to determine its impact on selecting optimal sites for dam construction. The results reveal that fourth-order streams offer the highest suitability due to their larger flow capacity, covering 11.4% of the area, while first-order streams, accounting for 48.9%, are less suitable. Slope analysis shows that 99.52% of the region features gentle slopes (0-5°), which are ideal for dam construction. Soil type analysis identifies Gleysols as the most favorable for dam foundations, covering 86.1% of the area. Precipitation levels, particularly in areas receiving 1200-2200 mm of rainfall, are deemed highly suitable for dam operations. The study further reveals that 96% of the land cover consists of barren land, which is advantageous for construction due to minimal land-use conflicts. A detailed cross-sectional profile analysis of six proposed dam sites identified Dam 5 as the most suitable location, offering stable terrain, a consistent cross-section, and favorable hydrological conditions. Other sites, such as Dam 1 and Dam 6, show promise but require additional engineering modifications. The study’s findings contribute valuable insights into sustainable water resource management and infrastructure development in regions with similar environmental conditions. Key recommendations include further feasibility assessments, environmental impact analyses, and consideration of the social and economic benefits of dam construction.
Geneva St Ramp: Replacement of Steel Girder Bridge with Post-Tensioned Concrete Structure on Existing Foundations
Authors: Mermigas Konstantinos Kris
Published: January 2025

The ramp was built in 1963 as part of the original Hwy 406 south of St. Catharines. The existing bridge consisted of five simply supported spans of 22.6 m, each supported by two steel plate girders composite with a concrete deck. The ramp was regularly maintained through the years: a waterproofing membrane was added in 1979 along with sealed expansion joints, and the expansion joints replaced again in 1998. In 2015, the condition of major components had deteriorated significantly and coupled with concerns for redundancy and structural steel details vulnerable to constraint induced fracture (overlapping welds), led to the decision to replace the superstructure.

The ramp has complex geometry consisting of a tangent, a radial curve and two spirals in plan, a longitudinal grade increasing up to 5%, and the 9.35 m cross-section has variable superelevation. The ramp spans over a valley. After considering several alternatives (including filling in the valley), a post-tensioned concrete solid slab deck of 0.7 m thickness was selected for the replacement superstructure. The new deck is 0.8 m wider and 20% heavier than the steel superstructure it replaces. The geotechnical engineer reanalysed the steel pile foundations with current practices and found potential to increase capacities, later confirmed through additional boreholes.

The deck is supported on four slender piers monolithic with the deck, and on the existing abutments where semi-integral deck ends support the wingwalls and approach slabs. The reuse of foundations was a defining feature of the project, key to the success of the selected alternative, saving time and cost in construction. Construction of the bridge started in July 2021 and was completed in September 2022. The project demonstrates that post-tensioned concrete bridges can be built competitively with girder bridges and contribute to sustainability.
Component management for structural reuse
Authors: Mao Siyi , Cao Wen-Jun
Published: January 2025

The construction industry is an important pillar of the global economy, putting significant pressure on resource consumption and environmental impacts. To relieve the burden, the concept of circular economy has recently been introduced to the construction industry. Component reuse represents a strategy with the highest potential for circularity, as it preserves the value of the structure to the greatest extent. Despite the potential, recycling remains the most prevalent circular strategy within the construction industry, resulting in many well-performed components being unnecessarily dismantled and destroyed. A key reason is the absence of reliable and user-friendly tools for evaluating components' reusability. To enhance the decision-making process and increase the reuse rate of components, this study proposes a BIM-based component management framework. The paper systematically discusses the inclusion, storage, usage, and display of the data that affects the component's reusability. The framework has been successfully applied to a bridge case study.
Seismic Behavior of Steel Beam to Box Column Connections
Authors: Santiago-Flores Alejandro , Tapia-Hernández Edgar
Published: January 2025

In recent years, the use of steel elements in building constructions in seismic regions has increased. Although steel structures have generally performed well during earthquakes, their seismic vulnerability significantly depends on the performance of their components. In this research, the results of two full-scale steel beam-to-column moment connections tested under cyclic loading are discussed. The prototypes were made up of box columns and I-shaped beams with an exterior beam-to-column joint. The physical full-scale cyclic testing was corroborated through nonlinear finite element (FEA). The discussion is centered on a detailed comparison of the obtained results from the experiment and numerical simulation, including stiffness, strength, excessive local damage, ductility, and deformation capacity. Recommendations are proposed for improving the seismic behavior of steel connections.

Published: January 2025

The aging of RC deck slabs on existing bridges is a serious social problem in Japan. Holes may appear on the RC deck slabs, obstructing road traffic. Therefore, a diagnostic technology that can quickly and accurately evaluate the structural integrity of RC slabs needs to be established. The authors have developed a new method for inspecting and diagnosing existing RC deck slabs using self- propelled impact vibration equipment (SIVE). In this study, the accuracy of measuring RC deck slab deflection was verified in a laboratory experiment. Also, impact load was applied to the RC deck slab of a composite bridge that had been in service for 56 years, and the deterioration tendency was evaluated from the deflection distribution. The correspondence between the evaluation and visual inspection results was then verified.

Published: January 2025

The development of advanced simulation and decision-making models presents an opportunity to enhance the assessment of infrastructure projects. This study aims to improve Pavement Management Systems (PMS) by incorporating data from Traffic Management Systems (TMS). The methodology uses TMS data to calculate fuel consumption resulting from traffic disruptions caused by maintenance actions. The proposed multi-objective optimization framework aims to minimize maintenance costs, pavement degradation, and fuel consumption. This framework employs a bottom-up approach for system-level optimization, serving as a decision-making tool for road networks that account for the stochastic dynamics of the network. The findings indicate that including fuel consumption as an objective in the optimization model alters decision outcomes and reduces the variability of decision policies.

Rebar corrosion and concrete cracking of corrugated steel web beams in chloride environment
Authors: Yunlong Xu , Junlong Zhou , Haiqing Cao , Jiaquan Li
Published: January 2025

This article establishes numerical models, analyzes corrosion damage mechanisms, and predicts the structural service life for the corrugated steel web bridge engineering in the chlorine salt environment. The aim is to comprehensively evaluate its corrosion resistance and safety, and formulate corresponding maintenance measures accordingly. The results indicate that rapid diffusion of chloride ions occurs during the initial stage of simulation, and after 50 years, there is little change in the distribution of chloride ion content within the corrugated steel web beam. The corrosion depth at various points on the surface of the steel reinforcement gradually increases over time, exhibiting significant uneven corrosion. The damage to the corrugated steel web beam is primarily caused by corrosion of ordinary steel bars that have not undergone anti-corrosion treatment. This corrosion is primarily concentrated at the interfaces between the concrete edges and the reinforcement. Adopting methods such as reducing the environmental chloride salt content, increasing the thickness of the reinforcement protective layer, and replacing it with denser concrete structures can effectively delay the occurrence of concrete cracking.

Authors: Siedziako Bartosz , Nord Torodd , Sibille Luigi
Published: January 2025

Structural Health Monitoring (SHM) is currently one of the fastest-developing branches of structural engineering. It is believed that the proper application of this technique can contribute to increased structural safety, optimized maintenance schedule, more accurate estimation of remaining useful life, developing of early warning systems as well as creating asset prioritization schemes. However, SHM has not been applied so far to ferry dock bridges in Norway despite being a critical part of the infrastructure equal to bridges where SHM has been the topic of extensive research in recent years. In this study, the potential benefits and challenges related to implementing the SHM system on ferry dock bridges are discussed. The following topics are briefly covered in this paper: damage detection, the feasibility of population-based SHM, the importance of tidal effects, and the identification of impact forces during docking operations.
Evaluation of reductions in carbon emissions from building construction due to innovative approaches to floor construction
Authors: Moor Gianni , O’Suilleabhain Colm , Liu Xinlu , Chen Janice , Dubs Rafael
Published: January 2025

This paper summarizes the findings of an analysis of the relative CO2 emissions associated with different approaches to the design of floor slabs in building construction, including the beams and columns that support the floor. Four approaches, including innovative methods such as re-use of concrete slab with the slab elements supported by post-tensioned beams, were assessed, and compared with a standard reference design. The analysis concluded that upfront carbon emissions may be drastically reduced by selecting suitable approaches to building construction. For example, a 70% reduction in these emissions was calculated for the approach involving re-use slab and post- tensioned beams, if recycled materials are used – a reduction that even exceeds the carbon saving associated with wood-based construction.
