Objective

To evaluate the impact of two energetic drinks on color stability (CS), surface roughness (SR) and microhardness (HV) of some ceramic and hybrid materials.

Materials and methods

A total of 72 square-shaped samples (0.8 mm in thickness, 10 mm in width and 12 mm in length) were divided into three groups (n= 24) according to the studied materials: Celtra Duo, IPS e.max CAD/CAM and Nacera Hybrid. Each group was subdivided into three subgroups (n= 8) according to the three immersion solutions applied: artificial saliva, Hype and Power horse energetic drinks. Samples were sectioned using an Isomet 4000 (Buehler, Lake Bluff, USA) and then stored in artificial saliva for 24 h before doing the baseline color, surface roughness and microhardness measurements. For determination of color change (ΔE), a reflective spectrophotometer was used. Surface roughness (SR) testing was carried out using an optical profilometer with a built-in camera and the microhardness (HV) investigation was performed with a Microhardness Digital Tester. After 60 days of immersion in energetic drinks, these measurements for color stability, surface roughness and microhardness were repeated in the same way. Data were tabulated and analyzed using a two-way ANOVA followed by one-way ANOVA and Tukey'spost-hoctest with a significance level assigned atP≤ 0.05 for all tests.

Results

Statistical analysis revealed significant differences between studied groups for CS (P= 0.031), SR (P= 0.012) and HV (P= 0.028). Celtra Duo recorded the lowest color change (0.57 ± 0.09) and surface roughness (0.2499 ± 0.0033) and greatest microhardness (659.62 ± 6.10) with all immersion solutions. Nacera Hybrid material showed poorer values in all investigated properties compared to Celtra Duo and IPS e.max ceramics. For all studied materials, the greatest effect of immersion solutions on CS, SR and HV was exhibited by Power horse followed by Hype and artificial saliva.

Conclusions

The energetic drinks studied significantly increased SR and decreased CS and VH of Nacera Hybrid. Celtra Duo and IPS e.max CAD/CAM ceramics showed greater resistance to acidic energetic drinks compared Nacera Hybrid material.

Clinical significance

It is essential for the dentist to reinforce the awareness of patients regarding the risks of heavy consumption of energetic drinks. Nacera Hybrid material is a promising material but should not be used in esthetic restorations.

Authors: Saxena Aditi , Gupta Amit , Tiwari Nitesh
Published: July 2023

Brushless direct current (BLDC) motor aims to obtain high efficiency when compared to conventional DC motors due to several reasons. But when it comes to the control then its control is much more complicated due to the requirement of a phase supply switching circuit. Usually, the conventional and classical proportional integral derivative (PID) controller is used but it is quite cumbersome to tune its fixed gains. APID controller is used where PID fails to fulfill the objectives in varying situations. So, the adaptive proportional integral derivative (APID) controller is utilized to enhance the results. An artificial neural network (ANN) controller is one of the recent control methods, which gives accurate and precise results and utilizes ANN to give more accurate results. But it lacks fuzzy logic, that is, human tendency, and finally, the artificial neuro-fuzzy inference system (ANFIS) controller is concluded as the best controller to limit the speed of the BLDC motor. ANFIS includes all the advantages of controllers and provides the most accurate results. The mathematical model of all the controllers is discussed and its performance is simulated in MATLAB/Simulink. ANFIS includes all the advantages of controllers and provides the most accurate results.

It is now well established that the biology of cancer is influenced by not only malignant cells but also other components of the tumour microenvironment. Chronic inflammation and fibrosis have long been postulated to be involved in carcinogenesis. Chronic inflammation can promote tumorigenesis via growth factor/cytokine-mediated cellular proliferation, apoptotic resistance, immunosuppression; and free-radical-induced oxidative deoxyribonucleic acid damage. Fibrosis could cause a perturbation in the dynamics of the tumour microenvironment, potentially damaging the genome surveillance machinery of normal epithelial cells. In this review, we will provide an in-depth discussion of various diseases characterised by inflammation and fibrosis that have been associated with an increased risk of malignancy. In particular, we will present a comprehensive overview of the impact of alterations in stromal composition on tumorigenesis, induced as a consequence of inflammation and/or fibrosis. Strategies including the application of various therapeutic agents with stromal manipulation potential and targeted cancer screening for certain inflammatory diseases which can reduce the risk of cancer will also be discussed.

Published: July 2023

Selanik pek çok devlet için siyasi ve ekonomik olarak oldukça stratejik bir yer olarak görülmüş olup Selanik’in ele geçirilmesi Ege Denizi ve Balkanlar bağlamında da o devlete güç ve prestij kazandırmıştır. Selanik, uzun yıllar Türk hakimiyetinde kalsa da Birinci Balkan Savaşı’nın meydana getirdiği olağanüstü şartlar Osmanlı Devleti’nin buraya yeteri kadar güç aktarmasının önüne geçmiştir. Çalışmamız Selanik’in Yunanlılar tarafından ele geçirilmesinin ardın-dan şehirdeki Müslüman Türklere Yunan ve Bulgar askerleri tarafından yapılan saldırıları şehirdeki Alman konsoloslu-ğu üzerinden ele almıştır. Almanya’nın yirminci yüzyıldaki diplomatik gücünü de bir anlamda yansıtan çalışmamız Birinci Dünya Savaşı öncesindeki Türk-Alman ittifakını da göstermiştir. Çalışmamıza kaynak teşkil eden Almanya’nın Selanik konsolos raporlarına Alman Dışişleri Bakanlığı Arşivi’ndeki (Politisches Archiv des Auswärtigen Amts) Bal-kankrieg (1912-1913): Grausamkeiten in der Kriegführung kataloğundan ulaşılmış ve çevirisi de tarafımızca icra edilmiştir. Alman dışişleri bakanlığı arşivindeki 1912-1913 kataloğundan elde ettiğimiz bu raporlar şehirde Müslüman Türklere yapılan yağma, talan ve öldürme gibi olayları içermekle birlikte Yunan ve Bulgarların neden böyle bir yola başvurduklarını da bir anlamda ifade etmektedir.

Published: July 2023

Introduction: The Rico-Fontalvo classification of chronic kidney disease associated with obesity (CKD-AO) proposes four main pathophysiological mechanisms of renal function impairment with obesity. Type 4 CKD-OA addresses the issue of obesity in patients undergoing dialysis programs. An increase in body mass index > of 30 kg/m2 in the general population is associated with a higher risk of developing cardiovascular and metabolic diseases and higher mortality. In the group of patients undergoing hemodialysis therapies, the opposite occurs.
The objective of the review: The objective is to provide the reader with an update on the effect of weight, body composition, and body mass index in patients undergoing hemodialysis therapy in the short, medium, and long term.
Methods: A systematic search was performed in PubMed (Medline, United States Library of Congress); the search was restricted to references with no publication date limit. Keywords in English were used.
Conclusion: The increase in body mass index >25 Kg/m2 in the population group of patients undergoing hemodialysis treatments has a protective effect, decreasing mortality in studies carried out with 3 to 5 years of follow-up; At a longer follow-up time (12 years), according to observational studies, an increase in body mass index >30 kg/m2 seems to have a harmful effect equal to that of the general population. The benefit of an increase in BMI >25 kg/m2 and a decrease in mortality is more significant in men, African Americans, Hispanics, and those over 65.

Mejora del rendimiento de las aplicaciones Java usando cooperación entre el sistema operativo y la máquina virtual de Java
Authors:   , Becerra Fontal Yolanda
Published: July 2023

El uso de los entornos virtualizados de ejecución se ha extendido a todos los ámbitos y, en particular, se está utilizando para el desarrollo y la ejecución de aplicaciones con un alto consumo de recursos. Por lo tanto, se hace necesario evaluar si estas plataformas ofrecen un rendimiento adecuado para este tipo de programas y si es posible aprovechar las características de estas plataformas para favorecer su ejecución.

El objetivo principal de este trabajo ha sido ha sido demostrar que es posible explotar las características de los entornos virtualizados de ejecución para ofrecer a los programas una gestión de recursos que se adapte mejor a sus características.

En este trabajo demostramos que el modelo de ejecución de este tipo de entornos, basado en la ejecución sobre máquinas virtuales, ofrece una nueva oportunidad para implementar una gestión específica de recursos, que permite mejorar el rendimiento de los programas sin renunciar a las numerosas ventajas de este tipo de plataformas como, por ejemplo, una portabilidad total del código de los programas.

Para demostrar los beneficios de esta estrategia hemos seleccionado como caso de estudio la gestión del recurso memoria para los programas de cálculo científico en el entorno de ejecución de Java. Después de un análisis detallado de la influencia que tiene la gestión de memoria sobre este tipo de programas, hemos visto que añadir en el entorno de ejecución una política de prefetch de páginas que se adapte al comportamiento de los programas es una posible vía para mejorar su rendimiento.

Por este motivo, hemos analizado detalladamente los requerimientos que debe cumplir esta política y cómo repartir las tareas entre los diferentes componentes del entorno de ejecución de Java para cumplir estos requerimientos.

Como consecuencia, hemos diseñado una política de prefetch basada en la cooperación entre la máquina virtual y el sistema operativo. En nuestra propuesta, por un lado, las decisiones de prefetch se llevan a cabo utilizando todo el conocimiento que la máquina virtual tiene sobre el comportamiento dinámico de los programas y el conocimiento que el sistema operativo tiene sobre las condiciones de ejecución. Por otro lado, el encargado de llevar a cabo las decisiones de gestión es el sistema operativo, lo que garantiza la fiabilidad de la máquina.
Además, esta estrategia es totalmente transparente al programador y al usuario, respetando el paradigma de portabilidad de los entornos de ejecución virtualizados.

Hemos implementado y evaluado esta estrategia para demostrar los beneficios que ofrece al tipo de programas seleccionado y, aunque estos beneficios dependen de las características del programa, la mejora del rendimiento ha alcanzado hasta un 40% si se compara con el rendimiento obtenido sobre el entorno original de ejecución.
Techniques for improving the performance of software transactional memory
Authors:   , Stipić Srđan
Published: July 2023

Transactional Memory (TM) gives software developers the opportunity to write concurrent programs more easily compared to any previous programming paradigms and gives a performance comparable to lock-based synchronizations.
Current Software TM (STM) implementations have performance overheads that can be reduced by introducing new abstractions in Transactional Memory programming model.
In this thesis we present four new techniques for improving the performance of Software TM: (i) Abstract Nested Transactions (ANT), (ii) TagTM, (iii) profile-guided transaction coalescing, and (iv) dynamic transaction coalescing.
ANT improves performance of transactional applications without breaking the semantics of the transactional paradigm, TagTM speeds up accesses to transactional meta-data, profile-guided transaction coalescing lowers transactional overheads at compile time, and dynamic transaction coalescing lowers transactional overheads at runtime.
Our analysis shows that Abstract Nested Transactions, TagTM, profile-guided transaction coalescing, and dynamic transaction coalescing improve the performance of the original programs that use Software Transactional Memory.

Authors: Johnson Chelsea , G Nandini , Balivada Santosh K. , Prakash Surya
Published: July 2023

The cyclotron is a device used to create radioactive atoms with a short half-life (radioactive isotopes) that can be utilised for research and medical imaging. When nuclear and radiation facilities are utilized, serviced, or decommissioned, radioactive waste is produced. The amount of radioactive waste produced is greatly decreased by good operating procedures. Iodine-123, Technetium-99m, Iodine-131, Gallium-67 Thallium-201 and fluorine-18 fluorodeoxyglucose are among the radionuclides utilised in medicine. The most widely used gaseous/aerosol radionuclides are (aerosolized) technetium-99m, xenon-133, and krypton-81m. The use of radionuclides (radioactive element) for industrial process control and instrumentation, medical diagnostic and therapeutic purposes, as well as numerous uses in research, education, agriculture, geological exploration, construction, and other human endeavors, results in radioactive waste. These applications generate a variety of radioactive waste, which can come from sealed sources and be in solid, liquid, or gaseous form. If the trash containing considerable amounts of radionuclides is not handled properly, there may be serious concerns to both the environment and human health. Due to the wide variety of waste kinds addressed, special consideration must be paid to safety concerns and regulatory management. This article will examine the fundamental procedures for managing radioactive waste in compliance with the regulatory agencies like AERB (Atomic Energy Regulatory Board) and IAEA (International Atomic Energy Agency).

The media component of the socio-cultural space has a significant impact on the modern holiday calendar. The public holiday serves as a tool for the self-presentation of power, ideological and moral values that are significant for it, so the holiday resistance deserves special attention. The study is devoted to the media consideration image of a public holiday (on the example of the Day of Russia, the Day of National Unity, the Day of Family, Love and Fidelity, as the most resistant at the present stage), its ceremonial and ritual complex and the sacred meaning, both perceived through the media sphere and constructed mass media. The media texts of institutional and non-institutional mass media, collected by the thematic query of the Yandex search engine using the continuous sampling method, are considered, which makes it possible to identify both the official point of view and the ordinary people’s opinion. Semantic dominants of discourse, texts emotional markers are revealed. Used methods of semantic, contextual, typological analysis. The reasons for the resistance of the three considered public holidays in society have been established: the fuzziness of holiday meaningful component, the lack of a symbolic-ritual complex that is understandable and accepted by the holiday participants, an ill-conceived media strategy, that is, an ambiguous choice of the date, holiday symbols, and the vector of its popularization. An additional factor of resistance can be called the modern calendar transitivity and its oversaturation with festive events. The reflection study of the image of the holiday in the media space and the construction of its mass media is significant for understanding the festive culture transformation at the present stage, the conclusions can be used in methodological recommendations for holding holidays for educational and cultural institutions.
A Hybrid Physical-Virtual Educational Robotic Arm
Authors: Gonzalez Fernando Garcia
Published: July 2023

In the field of robotics education, introductory courses would ideally utilize heavy industrial arms for hands-on learning. This would provide students with valuable experience in joint programming, which involves direct control of each joint motor in the arm to accomplish desired path planning and differential movements. This practice requires consideration of the physical dynamics of the arm. However, the use of heavy industrial arms has several drawbacks. They are large and expensive, require specialized maintenance, can pose safety risks, and they typically do not allow for direct control of the joint motors. One solution is to use a small, lightweight, toy-like arm. While these are cost-effective and provide direct access to the joint motors without posing safety risks, their lightweight construction means they exhibit minimal dynamic behavior, which limits their educational value. Another solution involves a robotic arm simulator that uses a virtual arm. However, a virtual arm doesn't offer the same level of hands-on engagement and excitement as a physical arm. We propose a hybrid solution that combines a small physical arm with a virtual arm. This approach provides students with the experience of working with an industrial arm, but without the associated difficulties. We demonstrate how this approach successfully improved the completion rate of joint programming assignments, offering a promising solution for practical robotics education.

The infrared spectra of the air exhaled by several groups of volunteers were studied: those suffering from type 1 diabetes, bronchial asthma, and pneumonia. To record infrared spectra, a tunable quantum-cascade laser (QCL) was used. QCL emits in the wavelength range from 5.3 to 12.8 μm in a pulsed mode with a pulse width of 50 ns, a power of up to 150 mW, and a tuning step of 1 cm-1. The laser is optically coupled to an astigmatic gas cell of the Herriot type with an optical path length of 76 m. A difference was found in the intensity of selective lines of biomarker molecules in the spectra of exhaled air of healthy volunteers compared to similar indicators of volunteers suffering from a certain disease. For an example of methods such as the support vector machine (SVM), the k-nearest neighbors (k-NN) and the random forest algorithm (RandomForest), the possibility of classifying volunteers by the infrared spectra of their exhaled air is shown. The use of dimensionality reduction methods (PCA and t-SNE) made it possible to increase the accuracy of disease classification up to 98% in terms of the accuracy metric.

Lecturer performance assessment is one of the activities of monitoring and evaluating performance with the aim of supervising the learning process and ensuring that lecturers carry out their duties in accordance with policies and teaching materials that have been determined. Lecturer performance assessment is carried out by students at the end of each semester by assessing lecturers based on criteria related to lecture learning. The criteria assessed in college learning are learning aspects, technological proficiency, integrity, and inspiration. The results of the student assessment will be reported to the learning development and quality assurance institution, which can later be used to determine the best lecturer performance. In this research, we apply the MOORA method to help determine the best lecturer based on assessment results in lecture reasoning. In its implementation, the MOORA method performs calculations based on criteria and weight values that have been determined and produces a ranking that can be used to determine the best lecturer's performance. In this study, the highest ranking was on the VPB alternative with a final value of 0.138, while the lowest value was on the DAM alternative with a final value of 0.108.
To What Extent Is the Security Dilemma an Inescapable Feature of International Security?
Authors: Meng Qingyi , Zhang Haiyi
Published: July 2023

This essay attempts to explore to what extent the security dilemma is an inescapable feature of international security. The three main schools of thought in international relations theory offer different perspectives on this issue. Realism asserts that the security dilemma is entirely inescapable. Liberalism, on the other hand, acknowledges its inescapability but argues that it can be mitigated through international cooperation mechanisms. Constructivism takes a different approach, suggesting that the constructed “security dilemma” can be fundamentally overcome by changing interactive behaviors. While liberalism and constructivism challenge realism’s conclusion, neither perspective can successfully refute the notion that the security dilemma is an inherent feature of international security. Liberalism is more applicable to economic matters and lacks explanatory power in the realm of international security, while constructivism tends to be overly idealistic and lacks the ability to effectively address real-world problems.

China is characterized by a long history of development and a rich and colorful national culture. Folk dance culture shines in the field of excellent traditional culture. However, the progress of social development has led to the gradual extinction of folk dance. Preschool education, as the beginning stage of education in a person’s life, is a favorable time to embrace folk dance culture. By integrating folk dance into the stage of preschool education, it is conducive to carry forward the traditional culture of the nation and fostering national self-confidence and national pride in children while passing on the excellent traditional culture. Therefore, it is urgent to explore the path of combining folk dance culture with early childhood education.

Synoptic studies on natural products have been conducted as a result of the lack of a potential remedy and associated flaw in allopathic medicines, as these items have been found to be less harmful and more affordable. The identification and assessment of therapeutic potential in pharmaceuticals led to the development of novel, affordable medications for the treatment of a variety of ailments, including chronic wounds. To determine if plant extracts can effectively cure wounds, in-vitro cell scratch testing is a practical and affordable method. Traditional herbal remedies for treating wounds include Azadirachta indica (A. indica) and Aloe barbadensis miller (Aloe vera, A. vera). The goal of the current study was to assess the ability of a polyherbal formulation (A. vera and A. indica) to promote wound healing in Wistar albino rats utilising excision, incision, and dead space wound models. A. vera and A. indica extracts were used in varied concentrations to create formulations PHF1 through PHF5. Utilising criteria like physical appearance, pH, extrudability, viscosity, spreadability, homogeneity, grittiness, and stability study, the generated polyherbal gel formulation was assessed. On days 3, 6, 9, 12, 15 and 21, as well as day 24, wound healing was observed along with the percentage of wound contraction, epithelialization period, hydroxyproline content, tensile strength, granuloma weight, and protein content (dead space wound models). In an excision wound model, polyherbal gel PHF4 demonstrated percent wound contraction in 12 days, and Groups II and IV saw considerably (P 0.01) shorter epithelialization times. In incision wound models, the animal group treated with polyherbal gel PHF4 demonstrated significantly higher levels of hydroxyproline than all other formulations as well as significantly higher tensile strength. PHF4 demonstrated the best efficacy in dead space wound models compared to other extracts and was significantly different from the treatment group in terms of granuloma weight and protein content. It can be said that poly herbal formulations have wound healing properties, possibly as a result of their epithelization, supporting the traditional assertion that they can be used to treat many human wound types.
