Published: February 2024

:

Thymus plays a crucial role in cellular immunity by acting as a warehouse for proliferating
and differentiating lymphocytes. Thymic stromal cells educate T-cells to differentiate
self from non-self antigens while nurse cells and thymoproteasome play a major role in the maturation
and differentiation of T-cells. The thymic conditions dictate T-cells to cope with the risk
of cancer development. A study was designed to demonstrate potential mechanisms behind the
failure to eliminate tumors and impaired immune surveillance as well as the impact of delay in
thymus regression on cancer and autoimmune disorders. Scientific literature from Pubmed;
Scopus; WOS; JSTOR; National Library of Medicine Bethesda, Maryland; The New York
Academy of Medicine; Library of Speech Rehabilitation, NY; St. Thomas’ Hospital Library;
The Wills Library of Guys Hospital; Repository of Kings College London; and Oxford Academic
repository was explored for pathological, physiological, immunological and toxicological
studies of thymus. Studies have shown that systemic chemotherapy may lead to micro inflammatory
environment within thymus where conventionally and dynamically metastasized
dormant cells seek refuge. The malfunctioning of the thymus and defective T and Treg cells,
bypassing negative selection, contributes to autoimmune disorders, while AIRE and Fezf2 play
significant roles in thymic epithelial cell solidity. Different vitamins, TCM, and live cell therapy
are effective therapeutics. Vitamin A, C, D, and E, selenium and zinc, cinobufagin and dietary
polysaccharides, and glandular extracts and live cell injections have strong potential to restore
immune system function and thymus health. Moreover, the relationship between different ages/
stages of thymus and their corresponding T-cell mediated anti-tumor immune response needs
further exploration.
Valoración técnico constructiva del conjunto ferroviario “Talleres de Bello”
Authors: Benavides Uribe Ricardo , Mejía Barrera Carlos
Published: February 2024

La construcción y el funcionamiento de ferrocarriles en Colombia fue uno de los hechos más significativos para el desarrollo económico, social y cultural del país en el siglo XIX. Este hito histórico tuvo lugar en el departamento de Antioquia, donde se materializó una línea férrea propia, mejorando las condiciones de movilidad a la vez que se construía, en diferentes lugares de su trazado, la infraestructura necesaria para su operación, como las estaciones y los talleres. Si bien para el Ministerio de Cultura de la Nación, las estaciones de los Ferrocarriles son bien de interés cultural y patrimonial de suma importancia para la nación, dicha declaratoria no incluye de manera directa los talleres donde se hacían los mantenimientos necesarios para el correcto funcionamiento de los ferrocarriles. La valoración técnico – constructiva, trata de analizar el conjunto “Talleres de Bello” desde una perspectiva más holística, es decir, desde los aspectos generales de su funcionamiento, y de las técnicas asociadas a las tipologías constructivas de los edificios que comprenden el conjunto ferroviario, en su estructura y cerramientos, tratando de revelar de alguna manera las técnicas constructivas de época y el impacto que representa para el estudio del patrimonio como movilizador de la innovación técnica y tecnológica en la arquitectura, la ingeniería y la construcción

Reversible total atrioventricular block in a very high-risk non-ST-elevation myocardial infarction (NSTEMI) during conservative treatment in a limited resource setting: a case report
Authors: Susanti Mareta Anggraeni  , Ruth Grace Aurora
Published: February 2024

Total atrioventricular (AV) block is the most common type of conduction disorder found in acute coronary syndrome (ACS), which requires timely recognition and treatment. This case report aimed to present conservative medical treatment for managing total AV block (TAVB) in a very high-risk non-ST-elevation myocardial infarction (NSTEMI) in a rural area. We reported a patient with TAVB in a very high-risk NSTEMI. The patient was hemodynamically unstable and needed immediate percutaneous coronary intervention (PCI). Due to limited facilities and difficult access to immediate PCI, the patient was treated conservatively with the NSTEMI protocol. Epinephrine, as a β-adrenergic agonist, was administered to improve hemodynamic status. During conservative treatment, TAVB was converted into the first-degree AV block on the third day of intensive care. In a setting where revascularization strategies and pacemaker implantation are not feasible, administration of antithrombotic agents and β-adrenergic agonists can be considered to manage TAVB with NSTEMI with close monitoring.

Published: February 2024

Osteosarcoma is the most common primary bone tumor malignancy, accounting for 30 - 80% of all primary bone tumors. It is presented in a bimodal distribution manner with the age of onset divided into two groups, 10-20 and >60 y.o. Various factors have significance in the patient's prognosis, including the expression of cyclin-dependent kinase 4 (CDK4). This CDK4 has an essential role in the pathogenesis of osteosarcoma through inactivation of the Rb gene, which is associated with the patient's survival. This study was conducted to evaluate the correlation between CDK4 expression and the survival of osteosarcoma patients. It was a cross-sectional study involving 50 patients diagnosed with osteosarcoma based on clinical, radiological, and histopathological examination. Available formalin-fixed paraffin-embedded (FFPE) samples were retrieved for immunohistochemical (IHC) staining of CDK4. The survival data was collected from medical records. CDK4 expression and survival data were analyzed statistically using the Kaplan-Meier curve. Out of 50 subjects, CDK4 was found to be expressed in 38 samples (76%). The group with negative CDK4 showed a slightly longer overall survival (by 0.2 mo) than the positive CDK4 group. However, these results were not statistically significant (p = 0.821). In conclusion, the overexpression of CDK4 may not directly affect the survival rate in osteosarcoma. Other factors need to be considered to understand the complexity of the disease.
Three Faces of the PKS Political Party in the Formulation of the New Energy and Renewable Energy Bill
Authors: Wiguna Bangkit Adhi , Lay Dhivana Anarchia Ria , Mayasari Diana , Leonard Edo Christian
Published: February 2024

Political parties play an important role in aggregating people's interests, including in the formulation of the New Energy and Renewable Energy Bill (RUU EBET) or the EBET Bill, both at the central and regional levels. This study aims to look at the dynamics between the three faces of a political party, namely the party in the public office, central office, and at the grassroots level (Katz & Mair 1993), during the formulation of RUU EBET or the EBET Bill. Using the Prosperous Justice Party (PKS) as a case study, this research finds that parties in the public and central office actually depoliticize the roles of parties at the grassroots level. This depoliticization manifests itself in three ways: (1) assumptions about the inability of party structures at the regional level to discuss the EBET issues, (2) not including the interests of developing EBET at the regional level as part of the EBET Bill, and (3) narrow definitions and restrictions of the EBET Bill as a central and elite issue.

Authors: Bretón Mora Fabiola Galicia , Alarcón Acosta Rafael
Published: February 2024

The main purpose of this article is to analyze the labor market integration of documented and undocumented skilled Mexican immigrants in Los Angeles Metropolitan region during the global recession of 2008. To this end, we use a mixed methodological approach. From the quantitative perspective, we analyze data from the American Community Survey. The qualitative approach includes 20 open-ended interviews with Mexican skilled immigrants. The main findings reveal that skilled immigrants were not negatively affected by the global recession. In addition, legal immigration status turned out to be the most important factor in differentiating those who obtained a skilled occupation and those who did not. However, some immigrants, including those who were undocumented, were able to strategically use their investment in human capital and their access to professional social networks in order to obtain professional occupations.

Published: February 2024

This study aims to verify the hypothesis that Information Literacy is a key course in the professional development of students. The authors review the obstacles, interests, and goals of students after their completion of the subject in Information Literacy. Quantitative survey-based research was conducted online at Transilvania University of Brasov. The literature was revised by scientometric methods in order to analyse the most relevant and highly cited articles published in Web of Science. Emotion Analysis method was used, since it is a fast method to scan students’ feelings. Students from Generation Z, the digital native nowadays, have remarkable digital skills and use information sources mainly from the digital environment. In this respect, Informational Literacy courses need to keep pace with the mentality and information behaviour of new generations. The hypothesis was thus supported; the students need this course because subjects like Copyright, Search Strategies, and Databases are of interest. Moreover, these informational research skills are important in professional development. This critical evaluation of Generation Z education may interest those studying trends in education and students’ needs.
Las ideas jurídicas y políticas de Aegidius Romanus: entre la lealtad al papa y la lealtad al rey
Authors: Sánchez de la Barquera Arroyo Herminio
Published: February 2024

Gil de Roma fue testigo de las convulsiones propias del fin del apogeo medieval y del inicio de la decadencia en el gótico tardío; entre los fenómenos propio de esa época está la lucha entre los señores feudales y la monarquía, trance del que saldrían fortalecidos los reyes. Los señores hallaron en la Iglesia a una aliada decidida, pero que a la postre también saldría derrotada. Gil de Roma participó en la formulación de la bula más famosa de la Edad Media: Unam sanctam (1302), la formulación más extensa de la pretensión universal del papado; pero también contribuyó a la educación política de Felipe IV de Francia, uno de los adversarios más férreos de los papas. El texto reflexiona sobre estas dos posturas aparentemente antagónicas y expone los argumentos y las motivaciones de este brillante pensador originario de Roma.

A Study of Role and Applicability of Data Mining Techniques in Intrusion Detection Systems
Authors: Pandey Arun
Published: February 2024

Abstract: The swift development of computers technologies changed the way data and information were kept. The risk of this data being exposed to uninvited and unauthorized users arises with this new paradigm of data access. Numerous systems have been created that examine data to look for deviations from a user's or system's typical behavior or look for a known signature in the data. Intrusion Detection Systems (IDS) is the name given to these systems. These systems use a variety of approaches, including machine learning algorithms and statistical methodologies. With the massive rise in the use of network-based services and information sharing on networks, network security has emerged as the fundamental component. The integrity, confidentiality, and availability of computer and network resources are all seriously compromised by intrusion, which also poses a severe risk to network security. Network audit data classification by humans is a costly, time-consuming, and laborious task. An intrusion detection system (IDS) is one tool used to find anomalies and attacks on a network. The network intrusion detection system has made extensive use of data mining techniques to extract valuable information from vast amounts of network data. This work proposes a hybrid model that combines two distinct intrusion detection techniques: anomaly-based and signaturebased. The model is separated into two stages. Systems for detecting intrusions make use of audit data produced by network devices, operating systems, and application software. These sources generate enormous databases that contain tens of millions of records. Data mining, which is the process of extracting meaningful patterns from a sizable amount of information, is used to analyze this data. The presented paper deals with the role and the applicability of data mining techniques in designing and developing the IDS Systems.

Published: February 2024

Abstract: In order to facilitate the security personnel to identify the items in the X-ray image, it is necessary to enhance the security X-ray image to highlight the color, edge, shape and other details of the different items in the image, so that the security personnel can identify the inspected items more accurately and quickly, to ensure the safe operation of the airport. Aiming at the problem of color distortion in CLAHE enhanced airport security X-ray images, an X-ray image enhancement algorithm combining USM+CLAHE is proposed. In this work, First, we calculate the grayscale images on the R, G, and B channels of the X-ray image and perform Contrast Limited Adaptive Histogram Equalization (CLAHE) enhancement respectively, and then merge the enhanced R, G, and B grayscale images. Next, we perform the Unsharp Mask (USM) sharpening operation on the Xray image enhanced by CLAHE, and finally merge the original image and the USM sharpened image according to the weight. The experimental results show that the USM+CLAHE algorithm can effectively enhance the security X-ray image, and at the same time can suppress the color distortion of the enhanced image.

Towards Understanding of the Plastic Zone Thermal Residual Stresses in Functionally Graded Materials
Authors: Khouja Farag A.
Published: February 2024

Abstract: Functionally graded materials (FGM’s) are advanced composites consisting of two or more materials whose composition and structure changes gradually over the volume, leading to gradual change in its property. Typically one component is a ceramic, while the other is metal or metal alloy. In common embodiments, the composition can change gradually from all ceramic on one side to all metal on the other side, the ceramic contributing high resistance to temperature with the metal contributing high ductility. It’s a way to incorporate favorable properties of two materials into different locations of a single structure. In ideal cases the composition changes gradually but for manufacturing reasons, the changes occurs in homogeneous layers. The boundaries between the layers cause thermal residual stresses to arise, especially during material processing and in cases of cyclic loading. These thermal residual stresses are a result of differences in the thermal expansion coefficient of the varying compositions of materials. Thermal residual stresses may lead to cracking and ultimate failure of FGM’s. This study investigates the formation of thermal residual stresses for a Nickel-Alumina Ni-Al₂O₃ FGM. The Ni-Al₂O₃ system is chosen because it is one of the most common systems used in practice. This work explores the formation, impact and minimization of thermal residual stresses for a number of practical conditions that may arise during processing. All relevant properties are calculated using the rule of mixture equations.

Este estudio tuvo como objetivo evaluar el efecto de Se administrado a través de bolos intrarruminales en cabritos y correlacionarlo con los niveles del mineral y los biomarcadores de estrés oxidativo en sangre. Se utilizaron 15 cabritos de 8 a 9 semanas de edad de la raza Alpina con un peso promedio de 13.7 kg y se dividieron en tres grupos: grupo Selenio (se administró un bolo de selenito de sodio por vía oral, con un contenido equivalente a 90 mg de Se); grupo Se-SMZ (se administró un bolo de selenito de sodio vía oral, con un contenido equivalente a 90 mg de Se y 4 g de sulfametazina a); grupo Placebo (se administró un bolo placebo vía oral). Los niveles plasmáticos de Se se llevaron a cabo mediante la técnica de espectrofotometría de absorción atómica. La concentración de TBARS y GSH se estimó mediante espectrofotometría. La significancia establecida fue de P<0.05. Después de la administración de los bolos de selenio y Se-SMZ, los cabritos aumentaron los niveles de Se en plasma a partir de las 3 h después de la dosificación, con una diferencia significativa (P<0.05) entre el Se vs Se-SMZ hasta las 3 y 24 h. Los grupos de animales a los que se les administró el bolo presentaron variabilidad en los niveles plasmáticos de TBARS sin mostrar una tendencia constante (P>0.05). Los niveles de GSH no mostraron diferencias significativas entre los grupos. En conclusión, los bolos con Selenio y Se-SMZ aumentaron los niveles plasmáticos de Se. Hubo una amplia variabilidad en los niveles plasmáticos de TBARS y los niveles de GSH no mostraron diferencias significativas relevantes entre los tratamientos. Los bolos fueron una buena alternativa para suplementar el Se a los rumiantes.

By exploiting the link between time-independent Hamiltonians and thermalisation, heuristic predictions on the performance of continuous-time quantum walks for MAX-CUT are made. The resulting predictions depend on the number of triangles in the underlying MAX-CUT graph. We extend these results to the time-dependent setting with multi-stage quantum walks and Floquet systems. The approach followed here provides a novel way of understanding the role of unitary dynamics in tackling combinatorial optimisation problems with continuous-time quantum algorithms.

THE MEDIATING ROLE OF CONSUMER SATISFACTION IN ENHANCING LOYALTY TOWARDS MALAYSIAN HALAL-CERTIFIED FOOD AND BEVERAGES
Authors: Madun Azian , Kamarulzaman Yusniza , Abdullah Noorhidawati
Published: February 2024

The certification for halal food and beverage is issued by various organisations around the world. Nonetheless, the halal certification issued by the Malaysian government is often recognised as the most trustworthy and of the greatest quality. The purpose of this research is to look into the relationships between trust, customer expectations, religiosity, satisfaction, and loyalty, with a focus on the influence of satisfaction in increasing loyalty to halal-certified foods and beverages. A survey conducted among 399 Malaysian Muslims consumers shows that the highest correlation was between satisfaction and loyalty. Satisfaction was also the highest determinant for loyalty; while trustworthiness in the institution was the highest determinant in satisfaction. This study also found that satisfaction can increase loyalty. Findings of this study implies that the certifying institution should always increase and build their reputation among consumers, although the consumers may not necessarily understand the standards and process of certification. The findings also suggest that as long as consumers are satisfied with halal food and beverages, they will be more loyal to brands that carry Malaysian halal certification.
CURRENCY MANIPULATION FROM ISLAMIC MONETARY MANAGEMENT AND TRADE OUTLOOK
Authors: Widi Fariza Rachman , Oetomo Hening Widi
Published: February 2024

The word “competitiveness” in foreign exchange seems to dynamically widen. It does not solely refer to stronger against other currencies. Currency manipulation is the main reason, a monetary maneuver conducted by export-based countries to even depreciate their currency rate to maintain its competitiveness. Implemented years ago, it seems to become a warm topic once again since the US-China trade clash. The controversies emerged due to its tempting benefits to the exporter countries, yet hurting the importer countries. However, it seemingly violates no regulation in international trade law. Hence, the urge to review this policy from a wider perspective. This paper will review the currency manipulation from Islamic monetary management and trade principles, as Islam strongly urges in good pricing management which aims to benefit all trading parties and maqasidi resources control. The result shows that currency manipulation violates major aspects of Islamic monetary management and trade principles. The outcome also proposes the alternative principles scheme to elude the currency manipulation implementation for a long-term beneficial trade.

Este capítulo “Potencializando las actitudes del estudiante para la disminución de las problemáticas juveniles” proviene de una investigación de convocatoria proyecto de escuela titulada “Por el bienestar psicosocial y la calidad de vida: actitud de los estudiantes de instituciones educativas públicas frente a las problemáticas juveniles actuales en el municipio de La Plata”, toma como punto de partida el trabajo investigativo del grupo Desarrollo Sociocultural, afecto y cognición en los diferentes centros de la UNAD, estudiando las problemáticas que aquejan a la población de adolescentes y jóvenes en la actualidad (bull ying, consumo de sustancias psicoactivas, ideación suicida, embarazo en adolescentes, entre otras). Se investiga la actitud de los estudiantes frente a estas situaciones, analizando la influencia de estas, cómo se reflejan en su comportamiento, afecto y cognición, indagando cómo incide en formas inadecuadas de desenvolverse en su entorno. Como participantes 150 estudiantes de instituciones educativas públicas del municipio de La Plata entre adolescentes y jóvenes, que se evalúa la actitud desde tres elementos según el modelo ABC (affect, behavior and cognition), que han sido mencionados por Rebolledo (1994): en componente afectivo, conductual y cognitivo. La presente investigación se desarrolló desde el enfoque mixto, se trabajó la metodología Investigación Acción (IA), con instrumentos y técnicas como grupo focal, talleres investigativos, aplicación del Instrumento Escala de actitud ante las problemáticas juveniles y así se triangula los resultados obtenidos y se generaron estrategias de autogestión para la resolución de estas problemáticas encontradas.
La mínima participación laboral de la mujer en el campo tecnológico ¿es un problema de género o de capacitación?
Authors: Gómez Leguizamón Ingrid Johanna
Published: February 2024

Es evidente que la tecnología ha tenido un crecimiento monumental en estos últimos dos años, ya que la pandemia nos trajo un reto enorme al tener que pasar nuestra vida cotidiana a la virtualidad. A partir del año 2021 el crecimiento de oportunidades en este sector fue de un 8.5 % y para el año 2022 se espera que el crecimiento este alrededor de 9.4 %, esto de acuerdo con cifras entregadas por el Departamento Administrativo Nacional de Estadística (DANE, 2021).Pero estas cifras tienen en cuenta la participación de todo el sector, para poder analizar la participación por género en este campo tan “exclusivo para los hombres” debemos recurrir a otro tipo de estadísticas que lamentablemente nos entregan un panorama un poco desalentador, ya que se puede observar que el género femenino que se desarrolla laboralmente llega apenas al 23 % y en todo el mundo solo el 30 % de las mujeres son investigadoras del área de ciencias, tecnología, ingeniería y matemáticas, según el reporte generado por (ONU Mujeres, 2021).Estas cifras generan una gran inquietud, ¿por qué está tan sesgado este sector para las mujeres?, ¿es posible que el sector sea diseñado desde una propuesta en que los hombres son los únicos que pueden desempeñar estas labores?, ¿será que las mujeres no se sienten capacitadas para desarrollar estas actividades o mejor la sociedad se ha encargado de sectorizar los empleos o actividades que las mujeres pueden realizar? Son muchos los interrogantes que se generan con respecto a este tema, y el objetivo de esta investigación es visualizar una posible causa y tratar de generar alguna alternativa que permita brindar una visión diferente que aporte desarrollo a las mujeres y que procure servir de alternativa al sector tecnológico que sufre de grandes dolencias a la hora de conseguir personal calificado para estas labores.

En Colombia se calcula que más de un millón de personas pierden la vida o sufren heridas no fatales a causa de la violencia colectiva; partiendo de este hecho se observa una relación directamente proporcional entre la violencia y la salud mental, que como resultado enmarca a algunas víctimas de la violencia con afectaciones emocionales y psicológicas como la ansiedad, depresión, estrés y de forma crónica se ha podido observar que dentro de los trastornos más prevalentes como lo cita la Política Nacio-nal de Salud Mental del Ministerio de Salud en Colombia y Protección Social según encuesta realizada en 2015 se encuentra el TEPT. A partir de una revisión bibliográfica 2015 y 2020 se encuentran una serie de datos relacionados con investigaciones que ratifican el origen de estas afectaciones psicosociales en un mayor porcentaje de la población femenina causados por un alto grado de exposición a eventos traumáti-cos, lo cual permite identificar que existen unos factores de riesgo que inciden en el desarrollo de trastornos a partir de la exposición a hechos violentos. Por esta razón surge la necesidad de pensar en estrategias que aporten en unas nuevas dinámicas emergentes que fortalezcan el reconocimiento y la identificación del daño psicosocial, con una posible ruta que conduzca a la recuperación y al empleo de recursos de afrontamiento para hacer frente a una realidad en las víctimas. Tras la realización del estudio se concluye que se hace urgente continuar investigando en la temática e implementar herramientas que favorezcan la reparación del daño psicológico causado a la población afectada por el conflicto armado.

Chua?s circuit is the classic chaotic system and the most widely used in
serval areas due to its potential for secure communication. However,
developing an accurate chaos control strategy is one of the most challenging
works for Chua?s circuit. This study proposes a new application of super
twisting algorithm (STC) based on sliding mode control (SMC) to eliminate or
synchronize the chaos behavior in the circuit. Therefore, the proposed
control strategy is robust against uncertainty and effectively regulates the
system with a good regulation tracking task. Using the Lyapunov stability,
the property of asymptotical stability is verified. The whole of the system
including the (control strategy, and Chua?s circuit) is implemented under a
suitable test setup based on dSpace1104 to validate the effectiveness of our
proposed control scheme. The experimental results show that the proposed
control method can effectively eliminate or synchronize the chaos in the
Chua's circuit.

Triboelectric nanogenerators (TENG) take the advantage of coupling effect for
harvesting energy in the area of electronics for various self-powered
applications. These nanogenerators are capable of converting energy in our
surroundings into electrical energy by using the process of electrostatic
induction and contact electrification. Triboelectric layers of a TENG are
formed basically with the use of various polymers, metals and other
inorganic materials like PTFE (Poly tetra fluoro ethylene), PDMS
(polydimethyl siloxane), FEP (Fluorinated ethylene propylene) and Kapton.
Selection of different materials for the device fabrication is very
important since it contribute towards the triboelectric effect and also
forms the fundamental structure for the proposed TENG device. In this review
article, we emphasis mainly on various triboelectric materials considering
factors such as stability, flexibility, power density etc., to improve upon
the electrical output of the devices for different applications.

Introduction. According to the data obtained from the American Orthodontic
Society survey conducted in 2015, the number of adult patients that
requested orthodontic treatment increased from 14% to 27% between 2010 and
2014. Because of the increased age of the patients, fixed orthodontic
treatment is expected to be performed on restored teeth, including all
ceramic restorations. The objectives of the present study were to evaluate
the influence of different surface treatments on the bond strength of
ceramic brackets to lithium disilicate ceramic and to determine the mode of
fracture. Material and method. 45 ceramic rectangular specimens were
obtained from lithium disilicate CAD/CAM blocks which were divided in five
groups according to the performed surface conditioning method: 1. grinding
with a fine diamond bur (control group); 2. sandblasting with 29 ?m alumina
(Al2O3); 3. etching with 4% hydrofluoric acid (HF); 4. sandblasting followed
by conditioning with a universal primer - silanization (Al2O3 + S); 5. HF
acid etching followed by silanization (HF + S). Shear bond strength test was
performed after storing the samples in water bath for 7 days. All of the
fractured samples were analyzed with optical microscope to determine the
type of fracture. Results. HF acid etching followed by silanization
performed the highest bond strength of 8.03 MPa, while sandblasting followed
by silanization - 6.69 MPa. Mechanical surface conditioning with either HF
acid etching or sandblasting resulted in significantly lower bond strength
(2.65 MPa and 1.51 MPa respectively). Mainly adhesive mode of fractures was
noticed after sandblasting and silanization, indicating minor chance of
damaging the ceramic restoration after debonding, at the end of the
orthodontic treatment, unlike the ceramic specimens in the Group 5 (HF + S)
with 42.8% mixed and 14.4% cohesive fractures; 100% adhesive fractures were
observed after mechanical treatments. Conclusion. According to the SBS test
results and fracture type, sandblasting followed by the application of a
universal primer can be considered as an adequate method for conditioning
the lithium disilicate ceramic restorations before the bonding of ceramic
orthodontic brackets.
