Among the most common dental problems, dental caries and trauma lead to the development of cavities and even tooth loss. Therefore, new regeneration techniques that are effective and toxic-free are needed. The use of scaffolds has created possibilities for the regeneration of tooth structure. Hydrogels made of hyaluronic acid have drawn many attention in regenerative medicine. Consequently, the objectives of the study were to estimate the impact of hyaluronic acid on pulp regeneration using histological evaluation and immunohistochemical localization of vascular endothelial growth factor (VEGF). The entire sample consisted of 20 teeth (right and left upper central incisors) from ten rabbits, Their ages were between 10 and 12 months. They were used for pulp exposure and coronal pulp tissue removal. After pulp exposure, hyaluronic acid hydrogels were injected into the pulp chambers of the right upper central incisors in the experimental group to promote pulp regeneration. The pulp chambers of the left upper central incisors considered as the control group, and they were temporarily filled in without the injection of hyaluronic acid. The histological and immunohistochemical evaluations were done in two time periods: the first and second week after pulp exposure. The histological results showed the formation of reparative dentin in the experimental group with a high mean value (56.3) regarding predentin thickness, especially in the second-week duration, and a significant difference as compared with the control group. The immunohistochemical results disclosed that the experimental group showed strong positive expression for vascular endothelial growth factor in different pulpal cells with the highest mean value of the number of positively expressed cells (34.3) in the second- week duration, with a significant difference as compared with the control group. Hyaluronic acid hydrogel had a supporting function in pulp regeneration, according to the findings of the current study. This was demonstrated by an increase in the expression of VEGF throughout the cells in pulp tissue.

Authors: Krutilin A. A. , Krapchetova T. V. , Inkova N. A. , Pakhomova О. К. 
Published: January 2024

Alumina cement is a rapidly hardening hydraulic binder containing low-basic calcium aluminates in the final product. The alumina cement production by melting is widespread. Melting of the mixture consisting of bauxite and limestone is carried out in the temperature range of 1500 to 1600 °C, which entails enormous energy consumption and, accordingly, the higher cost of resulting products. The paper studies the possibility of reducing the melting point as well as the cost of the main mixture component bauxite via its replacement by aluminum-containing waste.Purpose: Suggest the dependence between the mixture composition and the Al2O3 content in the initial aluminum waste; determine the best annealing temperature for alumina clinker; study strength properties of the resulting alumina cement and the effect of introduced limestone on the main quality index.Methodology: The chemical composition of the aluminum waste (sludge and powder), raw mixtures, and resulting clinker are detected in laboratory conditions using spectrophotometry and flame photometry methods in accordance with the state standard. X-ray phase analysis of waste and clinker is based on the powder diffraction method and conducted on the Thermo Scientific ARL X'TRA Powder Diffractometer. Physical and mechanical tests are carried out in accordance with the state standard poly-fraction sand.Research findings: Laboratory studies show that aluminum waste (sludge and powder), consisting of gibbsite and boehmite in combination with limestone, is suitable for the production of alumina clinker. Depending on the initial Al2O3 content, their content in the raw mixture ranges from 60 to 75 %.Value: Depending on the composition, the fest annealing temperature for alumina clinker, is 1350 to 1400 ℃; the mineralogical composition of clinkers consists of 85–90 % calcium aluminates. Alumina cement strength determined in small test samples having normal density and the ratio 1:0, is high after 2 days and ranges from 33.7 to 40.6 MPa. The addition of 5 % crystalline limestone into cement accelerates the initial rate of hardening and improves the strength from 33.7 to 53.2 MPa after 2 days due to the additional formation of 3CaO·Al2O3·CaCO3·11H2O.

Published: January 2024

This research aimed to describe the dynamics of classroom interaction and examine the factors influencing it. The researcher utilized qualitative methods, including classroom observation, semi-structured interviews, and questionnaires. The findings revealed that the teacher predominantly led and controlled the interaction. Good interaction only occurs at the beginning of the lesson, so for the most part, the teacher initiates and the students only responded to the teacher by giving answers in the form of phrases or words. For interaction between students they are interacted with their friends most of the time. But, mostly, it was not related to the English topic discussed. The researcher also found several factors affecting classroom interaction, such as students' lack of motivation, hesitancy to speak and engage in class discussions due to limited vocabulary, embarrassment, and fear of making mistakes.

Стаття присвячена встановленню особливостей застосування категорії евіденційності у текстах публіцистичного стилю сучасної німецької мови.
Життя у суспільстві неможливе без спілкування між людьми. Як учасники комунікації, вони обмінюються різною
інформацією, виражають свої думки, почуття та намагаються передати свою точку зору опонентам. Часто комуніканти передають неперевірену інформацію, чужі думки та припущення. Тому в сучасному процесі спілкування виникає потреба вказувати на джерело інформації. Основною метою такої вказівки є намагання надати повідомленню більшої авторитетності.
Для німецькомовного медійного дискурсу характерне вживання інференційної та репортативної евіденційності. Зазначені види зумовлені тим, що зазначення джерела інформації є невід'ємними складовою професійного медійного тексту, оскільки журналісти, зазначаючи у своїх матеріалах думки інших (політиків, знаменитостей чи простих очевидців), можуть представити подію у світлі різних ідеологій, надати їй певну оцінку та у такий спосіб вплинути на думку аудиторії. Вказівка на джерело інформації є необхідною ознакою медіатексту, оскільки з її допомогою можна підтвердити чи спростувати достовірність тієї чи іншої інформації. Евіденційний маркер допомагає читачам перевірити факти і думки, висвітлені журналістом, та на основі цього самостійно сформувати власну думку. Вказівка на джерела є центральною ознакою медійного тексту, що надає йому потрібної об’єктивності. Саме тому евіденційність як мовна категорія відіграє провідну роль в інформаційному просторі будь-якої розвинутої лінгвокультури.

Authors: Utami Chyntia Cahya , Desanti Ririn Ikana , Halim Fransiscus Ati 
Published: January 2024

The study-case method was applied in this research at a stationery store. The problems derive from an observation of a stationary store called Andesta, a micro, small, and medium-sized enterprise (MSMEs) run by individuals who engage in stationery and document procurement. The problem is that transactions are not properly recorded, preventing the store from knowing the profits and losses incurred during a certain period. As a result, the availability of stocks coming in and out is unclear. This issue will be resolved by developing an integrated sales and inventory system. The prototype method is implemented in the system development lifecycle. The system will be constructed as soon as the design is completed and accepted by the business owner. The CodeIgniter framework and MySQL databases were used to build the system. The construction of the sales and inventory system is supposed to support stores in running their business processes more efficiently.

Published: January 2024

Weather information plays a crucial role in various sectors due to Indonesia's wide range of weather and extreme climate phenomena. Automatic Weather Stations (AWS) are automated equipment designed to measure and collect meteorological parameters such as atmospheric pressure, rainfall, relative humidity, atmospheric temperature, wind speed, and wind direction. Occasionally, AWS sensors may produce erroneous values without the technicians' awareness. This study aims to develop sensors error detection system for predictive maintenance on AWS using the Long Short-Term Memory (LSTM) model. The AWS dataset from Jatiwangi, West Java, covering the period from 2017 to 2021, will be utilized in the study. The study revolves around developing and testing four distinct LSTM models dedicated to each sensor: RR, TT, RH, and PP. The research methodology involves a phased approach, encompassing model training on 70% of the available dataset, subsequent validation using 25% of the data, and finally, testing on 5% of the dataset alongside the calibration dataset. Research outcomes demonstrate notably high accuracy, exceeding 90% for the RR, TT, and PP models, while the RH model achieves above 85%. Moreover, the research highlights that Probability of Detection (POD) values generally trend high, surpassing 0.8, with a low False Alarm Rate (FAR), typically below 0.1, except for the RH model. Sensor condition requirements will adhere to the rules set by World Meteorological Organization (WMO) and adhere to the permitted tolerance limits for each weather parameter.
