Relevance. The success of dental implant treatment in cases of reduced alveolar bone volume hinges on restoring bone to the required dimensions in each case. The guided bone regeneration (GBR) technique, which encompasses various techniques, holds a central role in oral reconstructive surgery and dental implantology due to its capacity for continuous improvement. The authors' experience with a modified GBR technique incorporating a situational Vicryl framework (SVF) has demonstrated enhanced effectiveness, with the potential to restore vertical bone volume by 5 mm or more. This study aimed to evaluate the advantages of the modified GBR technique using SVF compared to the conventional GBR technique.Materials and methods. This study is based on a comprehensive comparative analysis of two datasets: a retrospective evaluation of dental implant treatment outcomes in 210 patients who required alveolar bone volume restoration using the classical GBR technique, and clinical data from 40 patients treated with both the classical GBR technique and the proposed modified SVF technique The oral status of 40 patients included in the clinical analysis was characterized by partial edentulism, accompanied by mild to moderate alveolar bone deformities resulting from either inflammatory resorption or natural atrophy. The retrospective group 1 (comparisons) consisted of archival data of 210 patients. Retrospective data from 210 patients and clinical data from 40 patients were subjected to statistical analysis using parametric and non-parametric methods with IBM SPSS Statistics software.Results. A comprehensive comparative analysis of retrospective and clinical data revealed the following results. The value of the integrated "restored bone volume" parameter after vertical reconstruction in group 1 was 2-3 mm. The mean value of the integrated "restored bone volume" parameter after vertical reconstruction in group 2 was 3.20±0.96 mm, while in group 3, it was 4.60±1.63 mm for patients of both sexes. Comparison of the integrated "baseline deformation" parameter by technique showed a median deformation of 2.95 mm in group 2, treated with the classical GBR technique, and 4.95 mm in group 3, treated with the modified SVF technique. Similarly, the integrated "restored bone volume" parameter showed a median value of 2.95 mm in group 2 and 4.85 mm in group 3. The average value of the integrated "restored bone volume" parameter in group 2 was comparable to retrospective data from 210 patients in group 1.Conclusion. The comprehensive analysis of alveolar bone volume reconstruction using two GBR techniques, based on "baseline deformation" and "restored bone volume" parameters, demonstrated a significant advantage of the modified GBR technique compared to the classical technique.

Relevance. Sarcoidosis is a multisystem granulomatous disease of unknown origin, commonly presenting with bilateral hilar lymphadenopathy, pulmonary infiltrates, and involvement of the eyes, skin, gums, and oral mucosa. This clinical case illustrates the oral manifestations of this rare systemic disease. Gingival hypertrophy and soft tissue lesions on the lip mucosa were the initial signs of the condition. Following an extended diagnostic process, the patient underwent treatment by both a dentist and a rheumatologist, leading to a stable remission of the disease.Case description. This article presents a clinical case of sarcoidosis manifesting in the mouth as gingival hypertrophy and a soft tissue lesion on the upper lip. In most cases, a diagnosis of sarcoidosis is made before any oral symptoms appear. Diagnosing a systemic disease based on primary oral symptoms poses a unique challenge, as dental professionals may not always be familiar with the oral manifestations of systemic conditions. In cases of suspected sarcoidosis, the oral mucosa should be thoroughly examined, and systemic sarcoidosis should be considered in the differential diagnosis of granulomatous lesions in the mouth.Conclusion. Early initiation of treatment can significantly improve the patient's quality of life and prognosis.

Published: October 2024

Эффективная продолжительная эксплуатация насосных установок с центробежными насосами связана во многом с их работой без кавитации. Обеспечить работу насосов без кавитации на стадии проектирования и эксплуатации можно только на основании корректно выполненных расчетов кавитационных параметров. Сравнивая их с требуемыми параметрами, можно формировать необходимые режимы функционирования насосных установок. Особое внимание требуется уделять насосным установкам с частотными преобразователями, так как пересчет кавитационных характеристик при изменении частоты вращения рабочего колеса по имеющейся одной заводской характеристике далеко не всегда позволяет получить адекватную измененную кавитационную характеристику. Поэтому для крупных насосов и при достаточно малом кавитационном запасе предложена методика пересчета кавитационных характеристик, использующих две базовые кавитационные характеристики насоса. При использовании насоса со срезанным рабочим колесом необходимо использовать кавитационную характеристику для обрезанного колеса, которая зачастую несколько выше характеристики для номинального рабочего колеса. Еще одним фактором, который следует принимать во внимание во избежание кавитации в насосах, является учет газовой кавитации при определении имеющегося кавитационного запаса. Приведена широко использующаяся в зарубежной практике методика пересчета имеющегося допустимого кавитационного запаса на фактический, учитывающий наличие газовой кавитации.
The efficient long-lasting operation of pumping units with centrifugal pumps is achieved to a large extent by avoiding cavitation during the operation. To ensure the operation of pumps avoiding cavitation at the design and operation stage is only possible on the basis of correctly performed calculations of the cavitation parameters. By comparing the cavitation parameters with the required ones developing the essential operation modes of the pumping units is possible. Particular attention should be paid to pumping units with variable speed drives, since the recalculation of the cavitation characteristics while changing the rotation frequency of the impeller according to the one available plant characteristic does not always provide for obtaining an adequately changed cavitation characteristic. Therefore, for large pumps and with a sufficiently small cavitation NPSH, a method for recalculating cavitation characteristics using two basic cavitation characteristics of the pump is proposed. While using a pump with a sheared impeller, the cavitation characteristic for the sheared impeller shall be applied that is often just over the characteristic for the rated impeller. Another factor that should be taken into account to avoid cavitation in pumps is gaseous cavitation while determining the available NPSH. A widely used in foreign practice method for recalculating the available permissible NPSH to the actual one with account of the presence of gas cavitation, is given.

A New Framework for Food Catering Price Determination
Authors: Drejeris Rolandas , Samuolaitis Mindaugas 
Published: October 2024

This article aims to propose a reasonable quantitative (mathematical) expressions for the price calculation of food-manufacturing products. Little research has been conducted on the validity of food product pricing; thus we have identified a need for a thorough, systematic investigation in this area. The suggested three methods are also applicable for developing the artificial intelligence system to solve raw food material (resources) quantity management and other inventory issues in collaboration with the food suppliers. We consider the option of an appropriate pricing strategy in the profit-making catering and other food production firms to be a relevant scientific issue, which we have have addressed and proposed solutions for in this article. By analyzing different scientific assumptions and attitudes, informed quantitative decisions were made. We also developed and described quantitative expressions for determining the price of food products using mathematical formulas. Also, we found that a simple three-digit rule, based on logic and proportional modeling of actions, as the main instrument is the most effective approach for formulating these pricing models. Original and innovative mathematical methods for the price accounting of food production have been created and explained. We have also explained how each of the three suggested methods works, along with their advantages and disadvantages in certain situations. Using these recommended methods of pricing will allow food companies to achieve more appropriate commercial results and to make less expenditure for decisions regarding the pricing of food products. In the article, we explained how to calculate the prices of food and catering companies using simple math. The application of any of the three mentioned techniques regarding existing circumstance will enable food production companies to ensure a straightforward yet accurate determination of the product price that aligns with the current situation.

Incorporating English as an International Language in Teaching Materials: A Case of an EAP Course in Vietnam
Authors: Nguyen Phuong Anh 
Published: October 2024

The spread of English on a global language has resulted in the emergence of a new paradigm of English language teaching, English as an International Language (EIL), which switches the focus from native models to communicative effectiveness and the equal status of all varieties of English and cultures. In Vietnam, though the goal of communicative effectiveness in English language teaching (ELT) is acknowledged, EIL syllabus material design has been given little attention. This study aims to explore the perceptions of material developers regarding EIL incorporation in teaching materials and the actual extent of EIL integration in teaching materials of an English for academic course. The results show that there exists a mismatch between the material developers’ appreciation of EIL incorporation and their modest practices of incorporating EIL in teaching materials. The research also indicated that while the material developers equally value international target culture, culture(s) of future interlocutor and local culture, the priority in material design was given to culture of native speakers. The opportunities to develop skills to communicate across the differences are also given credits in teaching materials, as perceived and practiced in the material design of the course. The research suggests a pedagogical implication towards further incorporation of EIL in language courses to university students and the role of material developers in resonating material design with actual communicative contexts.
Translation Studies in German as a Foreign Language (GFL) in Africa (Nigeria). A Weapon Against “Waiting Room Dangers”
Authors: Fakayode Omotayo Ibukun 
Published: October 2024

The importance of translation in Additional Language Learning (ALL) cannot be overemphasized as there exists of late various studies in support of this fact. Extant studies on this issue have dealt with various aspects of translation about language learning in Europe, Canada, Australia and also in the US, although studies in this regard are not limited to these geographical boundaries. Moreover, these studies do not only focus on the impact of translation on ALL but also on various other issues like plurilingualism as it relates to translation in ALL. However, research in this regard are relatively scarce in the African context. As such, many studies done in Africa, particularly in Nigeria are limited in scope when it comes to the relevance of translation in learning German as a Foreign Language (GFL). This study therefore seeks to shed more light on how translation studies in GFL lessons in Nigeria could be useful as a weapon against “waiting room dangers”.

Abstract
We present optical/UV observations and the spectroscopic classification of the transient AT2023vto as a tidal disruption event (TDE) at z = 0.4846. The spectrum is dominated by a broad blueshifted He ii
λ4686 emission line, classifying it as a member of the TDE-He class. The light curve exhibits a persistent blue color of g − r ≈ −0.4 mag, long rise, and decline timescale, with a large peak absolute magnitude of M

g
≈ −23.2, making it the most luminous of the classical optical TDEs (H, H+He, He) discovered to date by about 1.5 mag. We identify the host galaxy of AT2023vto in archival Pan-STARRS images and find that the transient is located at the galaxy center. Modeling the light curves of AT2023vto, we find that it resulted from the disruption of a ≈8 M
⊙ star by a ≈107
M
⊙ supermassive black hole. The star mass is about 5 times larger than the highest star masses previously inferred in TDEs, and the black hole mass is at the high end of the distribution. AT2023vto is comparable in luminosity and timescale to some putative TDEs (blue featureless continuum), as well as to the mean of a recently identified population of ambiguous nuclear transients (ANTs). ANTs have been speculated to arise from tidal disruptions of massive stars, perhaps in active galactic nuclei, and AT2023vto may represent a similar case to ANTs but in a dormant black hole, thereby bridging the TDE and ANT populations. We anticipate that the Rubin Observatory/LSST will uncover similar luminous TDEs to z ∼ 3.

Published: October 2024

Background: In 205 health facilities, mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) rates were reduced from 7.4% to 2.1% between 2017 and 2020, respectively.Aim: To determine characteristics that potentially correlate to the change in MTCT rates between two time points.Setting: Study was conducted in Kenya, semi-urban and rural areas.Methods: A retrospective, cross-sectional, exploratory analysis of programme implementation at two points in time (2017 and 2020). Between 2017 and 2020, we compared over 170 mother–infant pairs where MTCT occurred to over 6000 mother–infant pairs where MTCT did not occur through the following factors: (1) location of health facilities, (2) mother and infant characteristics, (3) access to antiretroviral therapy (ART), and (4) viral load suppression. Bivariate and multivariable logistic regression models were used to identify factors associated with MTCT.Results: Factors significantly associated with reduced MTCT rates were time points, mother’s age, infant age at first test, proportions of mothers receiving ART, and maternal viral load. When restricting the analysis to the sub-counties contributing data at both time points, the results were similar; however, counties’ location became significant in the updated model, as did the interaction term for mother and infant receipt of antiretrovirals (odds ratio [OR]: 0.228; p = 0.04).Conclusion: What changed between 2017 and 2020 is a higher proportion of pregnant women living with HIV received ART. Also, unlike in 2017, in 2020, tenofovir disoproxil fumarate was the backbone of the ART regimen for the prevention of MTCT.Contribution: The findings can potentially inform efforts on elimination of mother-to-child transmission of HIV.
