A Novel Non-convex Tensor Function Based TRPCA for Foreground Detection
Authors: Lu Youyou , Chen Lixia , Wang Xuewen
Published: July 2023

In recent years, tensor robust principal component analysis (TRPCA) models have become increasingly popular in the field of foreground detection. However, traditional TRPCA models often struggle to accurately approximate sparse terms, leading to less precise foreground object detection results. To address this issue, we propose a new approach by introducing a non-convex tensor logarithmic function to constrain the sparse term, and develop a novel foreground detection model called Model A. In addition, in order to distinguish between dynamic background and sparse foreground more accurately, we also introduce another foreground detection model called Model B. In this model, we divide the background into static background and dynamic background, and incorporate a non-coherent term into the model to help differentiate between the dynamic background and the sparse foreground regions. The experimental results show that both Model A and Model B outperform six comparison algorithms in terms of foreground detection performance. Additionally, Model B demonstrates particularly strong proficiency in handling dynamic backgrounds. These findings highlight the effectiveness and superiority of the proposed models in foreground detection tasks.
Bohr phenomenon for certain subclass of harmonic mappings
Authors: Meher Akash , GOCHHAYAT PRIYABRAT
Published: July 2023

We study a subclass of univalent harmonic mappings, denoted by $T_{H}(\alpha, \gamma,\beta),$ which is harmonic analogue to the class $\mathcal{W}_{\beta}(\alpha, \gamma)$ due to Ali \etal\ (J. Math. Anal. Appl., 385(2), 808-822 (2012)), where $\alpha$ and $\gamma$ are non-negative real numbers and $0\leq \beta <1.$ We first compute the Bohr radius, improved Bohr radius, Bohr-Rogosinski radius for the family $T_{H}(\alpha,\gamma,\beta).$ Moreover, by making use of area and Jacobian bounds, various Bohr-type inequalities are also established. In particular, we present Bohr phenomenon for various classical subfamilies harmonic univalent mappings and also pointed out the relevant connections with the known results.

Background
Increasing evidence is appearing that ozone has adverse effects on health. However, the association between long-term ozone exposure and lung function is still inconclusive, especially in developing regions with high ozone levels.
Objectives
To investigate the associations between long-term exposure to ozone and lung function in Chinese young adults.
Methods
We conducted a prospective cohort study among 1594 college students with a mean age of 19.2 years at baseline in Shandong, China from September 2020 to September 2021. Lung function indicators including forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced expiratory flow at the 25th, 50th, and 75th percentile of the FVC (FEF25, FEF50, and FEF75) and mean flow rate between 25% and 75% of the FVC (FEF25-75) were measured. Daily 10km×10km ozone concentrations come from a well-validated data-fusion approach and the time-weighted average concentrations during 12 months before the lung function test was defined as the long-term ozone exposure. The associations between long-term ozone exposure and lung function indicators in Chinese young adults were investigated using a linear mixed effects model, followed by stratified analyses regarding sex and BMI (Body mass index).
Results
Each interquartile range (IQR) (8.9 µg/m3) increase in long-term ozone exposure were associated with a -204.3 (95% confidence interval (CI): -361.6, -47.0) ml/s, -146.3 (95% CI: -264.1, -28.4) ml/s, and − 132.8 (95% CI: -239.2, -26.4) ml/s change in FEF25, FEF50, and FEF25-75, respectively. Stronger adverse associations were found in female participants or those with a BMI ≥ 24 kg/m2.
Conclusion
Long-term exposure to ambient ozone is associated with impaired small airway indicators in Chinese young adults. Females and participants with BMI ≥ 24 kg/m2 have stronger associations.
A Study On Measuring An Objective Aspect Score In Forestry Analysis: Example Of Forest Roads And Landslide Areas
Authors: HATAY Taha Yasin , ÖZCAN Zübeyir , GÜMÜŞ Selçuk
Published: July 2023

In forestry, measurements are made to understand the state of natural ecosystems, their changes, and human impacts. These measurements are accepted as criteria in studies and used in evaluations and comparisons. Although the studies using these criteria vary, they are of great importance in studies on forest roads and landslide areas. While forest road construction activities affect ecological, economic and social factors in forestry, landslides negatively affect the environment and people. In this study, it is aimed to objectively and accurately measure the aspects of landslides and forest roads. The aspect value has been associated with exposure to sunlight, precipitation and winds that absorb soil moisture in the literature, and it has been concluded that it is an important criterion. The measurement and scoring of the aspect is generally done by visual and subjective methods in the literature. Therefore, a method which measures the aspect score more sensitive and universal is required. In the study, thirty forest roads and thirty landslide areas were selected from the Maçka Forestry Enterprise. These road and landslide areas were scored according to previous studies in the literature. The comparisons have shown that studies on aspect scoring are subjective methods that contradict each other in many ways. In order to eliminate this confusion, in this study, a pixel-based method that can be used for both accurate measurement of the aspect and objective aspect scoring is proposed. Since the hemisphere, the local winds and the precipitation are effective in scoring the aspect, the proposed method is suggested as a parametric model so that users can adapt it to their own work as they wish. The results showed that the proposed method is accurate and effective in measuring and scoring the aspect. In addition, the proposed method is shared as an open source ArcMap Toolbox to be delivered to the end-user.

Published: July 2023

Let $r$ be a positive integer, and let $k_1, k_2, \cdots,k_r$ be integers such that $k_i \equiv \pm 1 \pmod 9$ for all $1 \leq i \leq r$. In this article, we prove the existence of infinitely many positive integers $D$ such that the class numbers of the real quadratic fields $\mathbb{Q}(\sqrt{3D}), ~ \mathbb{Q}(\sqrt{3(D -1)}), ~ \mathbb{Q}(\sqrt{3(D -k_1^2)}), \ldots, ~ \mathbb{Q}(\sqrt{3(D-k_r^2)})$ are simultaneously divisible by $3$. This result gives an affirmative answer to a weaker version of a conjecture of Iizuka \cite{Iizuka}.

Authors: Muflih  , Suwarsi
Published: July 2023

Introduction: Hypertension and gastritis are prevalent health issues among adults, and effective community nursing care is essential for managing these conditions. Health education interventions can potentially improve knowledge, motivation, and adherence, promoting primary, secondary, and tertiary prevention measures. Purpose: This study aimed to implement community nursing care in the aggregate of adults with hypertension and gastritis problems through health education interventions. Research Method: A "one group pre-test and post-test design" was employed for this study. The intervention technique used was health education, focusing on health promotion. The outcomes measured included primary prevention, which was the level of knowledge; secondary prevention, which was motivation; and tertiary prevention, which was the level of adherence. Results: Before the health education intervention, 80% (8 respondents) of the community members had good knowledge about hypertension and gastritis, while 30% (3 respondents) had poor knowledge. Following the health education intervention that covered topics related to hypertension (Cucumber Juice) and gastritis (Honey ginger brew), the level of knowledge increased to 100%, with all respondents showing a good perception.

Published: July 2023

The proportion of zinc in the landfill increased as the popularity of Galvanized industry, dry battery industry, and it bring harm to the environment. Bentonite is a potential candidate for barriers in landfill due to its metal adsorption ability. This work studies the character of adsorption in natural bentonite and shanghai clay for Zn(Ⅱ). Factor influencing the adsorption of Zn(Ⅱ), such as pH, ion strength of Na, contact time, initial concentration of Zn(Ⅱ), adsorption temperature, were examined by batch-type sorption test. The obtained result show that the change of pH value and ion strength of Na has no significant effect on the Zn(Ⅱ) adsorption onto bentonite. This indicates the strong selectivity of bentonite for Zn(Ⅱ). The Zn(Ⅱ) equilibrium sorption capacity onto clay increases with the increase of pH value or the decrease of ion strength. The effect of contact time on the adsorption process was studied within the kinetic models. The pseudo-second-order, intra-particle diffusion and Elovih model could described well the Zn(Ⅱ) adsorption onto bentonite, because its R2༞0.9. The results show that both physical adsorption and chemical adsorption exist in the Zn(Ⅱ) adsorption onto bentonite or clay, but the main factor determining the adsorption rate is chemical adsorption. The effect of Zn(Ⅱ) initial concentration on the adsorption was studied within the adsorption isotherms. The results show that the adsorption process is controlled by chemical mechanism. The effect of the temperature on the adsorption was studied within the adsorption thermodynamics. The Zn(Ⅱ) adsorption onto bentonite is spontaneous, but not onto clay. The result of SEM, XRD-EDS and FT-IR was show that the adsorption mechanism of Zn(Ⅱ) onto bentonite and clay has van der Waals force, ion exchange, and chemical action such as inner-sphere complexation.
An Approach to Investigating the Behavior of RCC Coupling Beams
Authors: Bhunia Dipendu , West Roger P. , Bhaskar Jayakumar
Published: July 2023

The use of coupled shear walls has been one of the potential options as an earthquake resistant system in reinforced concrete composite high-rise buildings in recent times. Coupled shear walls consist of two shear walls connected intermittently by beams over their height. The behavior of coupled shear walls is strongly influenced by the coupling beams. When the coupled shear walls are subjected to earthquake motion, energy dissipates in the coupling beams and, depending on the design, also at the base of the shear walls. However, it is seen from past research that there is an inconsistency regarding behavior of such coupling beams, especially regarding their modeling parameters (the size of the coupling beam), evaluative parameters (plastic rotation and yield moment capacities) and their unrealistic boundary conditions. This paper aims to achieve consistency regarding the behavior of coupling beams and feasible boundary conditions using both experimental and numerical analyses.
“Better safe than sorry”: Behaviorally informed digital campaigns and their association with COVID-19 vaccine interest and take-up in Belize
Authors: Daga Giuliana , Kossuth Lajos , Boruchowicz Cynthia , Boo Florencia Lopez
Published: July 2023

Background: Increasing vaccine take-up has been key to curb the COVID-19 pandemic globally. However, vaccine acceptance and take-up has been a challenge in some regions such as the Caribbean countries. This paper analyzes the performance of different behaviorally informed social media campaigns on people’s engagement with information about the vaccination process and vaccine take-up in Belize, a country where despite of enough vaccine supply take-up was very low.
Methods: Using Belize’s Facebook platform (>230,000 users) and national administrative vaccination data at the district level, we conduct three types of analyses. First, we run linear regression models to analyze which of five behaviorally informed and sequentially displayed Facebook campaigns were better at predicting i) social media engagement with COVID-19 vaccination; and ii) COVID-19 vaccination uptake. Then, within one of the campaigns (e.g. the side-effects one) we conduct a randomized experiment to measure the effect on social media engagement of exposure to either positively (“Majority did not report discomfort”) or negatively framed messages, using words (“Few persons reported discomfort”) or numerical proportions (“3 out of 100 reported discomfort”). Social media engagement is measured by the number of people that clicked on the respective Facebook ad and visited the official vaccination site (“Clicks”) and the number of people that interacted with the ad through likes and different emojis (“Engagements”).
Results: Campaigns highlighting COVID-19 vaccine safety best predicted vaccination uptake (second and booster doses) and social media engagement. Emphasizing the vaccine´s effectiveness was associated with a higher uptake of first doses. These results match previous research showing that safety was one of the main concerns among Belizean citizens and that efficacy beliefs were important to increase the likelihood of uptake among the unvaccinated. Finally, informational messages related to side effects that were framed positively (“Majority did not report discomfort”) and using words (“Few persons reported discomfort”) were better at generating "Clicks” compared to those negatively framed and using numbers (“3 out of 100 reported discomforts”).
Conclusions: Highlighting COVID-19 vaccines´ safety and framing side-effect information positively (i.e., focusing on those who will not get them) with words might increase vaccination uptake and interest in low-uptake regions like the Caribbean.
A universal system for boosting gene expression in Eukaryotic cell-lines

Published: July 2023

We demonstrate a universal transcriptional regulatory design algorithm that can boost expression in a non-induced fashion for any constitutive promoter in eukaryotic cell lines. The system consists of a simplified transcriptional architecture composed of a minimal core promoter and a synthetic upstream regulatory region (sURS). The sURS was encoded by an oligo-library containing 189,990 variants, where each variant contained up to three motifs encoded with mixed-base synthesis technology. Motifs were chosen from a list of 41 transcription factor (TF) binding motifs conserved in the eukaryotic lineage. Using a machine learning and oligo library (OL-ML) approach, we identified at least 16 motifs which were associated with either a statistically significant expression boost or attenuation effect. We validated the boost and attenuation potential of these motifs using a set of unseen sURS designs, which contained multiple copies of them. The validation sURS experiments further indicated that a modular and generic set of grammar rules for boosting and attenuation may exist in yeast enabling a simple design algorithm for boosting the expression of any promoter. Finally, we demonstrated that this modular and generic set of grammar rules functions similarly in mammalian CHO-K1 and Hela cells. Our work provides a resource for the characterization of conserved regulatory grammar, as well as a tool for the design of functional promoters for industrially relevant alternative protein expression in various Eukaryotic cell lines.

В статье представлены фундаментальные идеи российской исторической полонистики ХIХ – начала ХХ века в преломление их в творчестве В.О. Ключевского. Оценочные подходы ученого к истории Польши сочетали признание фундаментальных идей российской исторической полонистики, консервативных и славянофильских, по сути, и отход от них на либерально-западнические позиции. В этом контексте научное наследие историка не исследовалось и специального комплексного историографического исследования по этой проблематике не проводилось.

The article presents the fundamental ideas of Russian historical polonistics of the 19th - early 20th centuries as refracted in the works of V.O. Kluchevsky. The scientist's evaluative approaches to the history of Poland combined the recognition of the fundamental ideas of Russian historical polonistics, conservative and Slavophile in essence, and a departure from them to liberal-Westernist positions. In this context, the historian's scientific heritage has not been studied and no special comprehensive historiographic research has been carried out on this issue.
Images of the Historical Disaster in Eyewitness Testimonies (on the Example of the Reflection of the Events of the Armenian Genocide in 1915)
Authors: Амбарцумян К.Р.
Published: July 2023

Статья предлагает к рассмотрению проблему роли отдельных источников личного происхождения в формировании представлений об исторической катастрофе и событиях ее маркирующих. По мнению автора, отдельные нарративы могут рассматриваться как средство конструирования исторической травмы и виктимизации исторического прошлого. Обращение к опыту осмысление событий геноцида армян 1915 г. показало целесообразность изучения с позиций интеллектуальной истории текстов свидетелей и очевидцев событий, но не только самих жертв. В исследовании были использованы тексты Г. Моргентау, Г. Фирбюхера и Р. де Ногалеса. Все три исторических фигуранта были иностранцами, которые по долгу службы оказались в Османской империи в период I мировой войны. Именно эти три текста вошли в арсенал документов виктимизации и криминализации армяно-турецких отношений. Репрезентация исторической катастрофы в данных нарративах имеет черты как типичности, так и уникальности. Общим местом стало определение ответственности, отличительной особенностью – разная степень вины, возлагаемая на младотурок и немецкие власти. Одним из средств виктимизации является ориентализм, который предполагает оценку событий не только как политическую и гуманитарную катастрофу, но и культурный конфликт.

The article deals with the problem of the role of ego-documents in the formation of image of historical catastrophe and the events that marks it. To the author’s way of thinking the personal narratives should be considered as a means of constructing historical trauma and victimization of historical past. Appeal to the experience of understanding the events of the Armenian Genocide of 1915 showed the expediency of studying from the standpoint of intellectual history the texts of witnesses and eyewitnesses of the events, but not the victims themselves. Appeal to the experience of understanding the events of the Armenian Genocide of 1915 showed the expediency of studying from the standpoint of intellectual history the texts of witnesses and eyewitnesses of the events, but not only the victims themselves. The texts of G. Morgenthau, G. Firbucher and R. de Nogales have been used in the research. All three historical personalities were foreigners who turned up in the Ottoman Empire during the First World War on duty. Precisely these three texts were included in the arsenal of documents of victimization and criminalization of the Armenian-Turkish relations. The representation of a historical catastrophe in these narratives has the features of both typicality and uniqueness. A common feature was the understanding of responsibility, a distinctive feature - a different degree of blame that was put on the Young Turks and the German authorities. One of the means of victimization is orientalism, which involves assessing events not only as a political and humanitarian catastrophe, but also as a cultural conflict.

Authors: Павлов А.А.
Published: July 2023

Публикуется перевод восемнадцатой книги «Этимологий» (гл. I–XV) Исидора Севильского (560–636). Труд Исидора, покоящийся в значительной мере на римской антикварно-грамматической и энциклопедической традиции, сам стал фундаментом средневекового энциклопедизма. В восемнадцатой книге рассматривается ряд важных для римского сознания сфер бытия, связанных с агональностью. Исидор, опираясь на свой «панграмматический метод», рассматривает войну, судопроизводство и различного рода состязания через призму терминов, с ними связанных. В предисловии к переводу кратко изложены сведения о структуре книги и ее источниках.

In this issue we publish the translation of the first part of the XVIII book Isidore of Seville’s “Etymologies”. This work is based appreciably on the Roman grammatical and encyclopedic tradition, and itself became the base of the medieval encyclopedism. In the eighteenth book the author considers some of the important spheres of the life for the Roman consciousness connected with сompetitiveness. As well as in other books, basing on his “pangrammatical method”, he results the Latin terminology connected with war, legal proceedings and a various sort of competitions. In the foreword to translation briefly discussed the structure of the book and its sources.

Published: July 2023

Introdução: Alveólise é uma alteração de patologia ósseo-gengival, que pode ocorrer durante o processo de rizólise. É caracterizada pela expulsão do elemento decíduo de seu alvéolo, expondo a raíz dentária na cavidade bucal, geralmente relacionada a traumatismo dentário ou a uma infecção crônica pela cárie dentária. Objetivos: Apresentar um caso clínico de alveólise do tipo deiscência total em dente decíduo, em um paciente com 9 anos de idade, gênero masculino, atendido na Clínica de Odontopediatria da Universidade de Ribeirão Preto (UNAERP). Relato de caso: Ao exame clínico intraoral observou-se exposição das raízes do dente 74, circundado por tecido levemente edemaciado e eritematoso. O paciente apresentava uma condição bucal insatisfatória, caracterizada pela presença generalizada de cárie e restauração provisória. Ao exame radiográfico evidenciou maior reabsorção radicular da raíz mesial quando comparado com a raíz distal, além do sucessor permanente (dente 34) em estágio 8 de Nölla. O diagnóstico foi de alveólise do tipo deiscência total. O tratamento indicado foi a exodontia do dente afetado, realizando acompanhamento pós-cirúrgico, e a completa erupção de seu sucessor. Não houve intercorrência durante o tratamento e o pós-cirúrgico foi satisfatório. Posteriormente, foi confeccionado um mantenedor de espaço funcional removível na arcada inferior, com o objetivo de não ocorrer a mesialização dos primeiros molares permanentes inferiores (36 e 46), e consequentemente perda de espaço para a erupção dos dentes 35 e 45. Conclusão: O protocolo clínico adotado foi assertivo, uma vez que, além do tratamento da alveólise, foram restabelecidas as condições de saúde bucal da criança.
Soft Tissue Recurrence of Plexiform Ameloblastoma in 8 years post Disarticulating Hemimandibulectomy: A Case Report
Authors: Dr. Manthan Kumar Das  , Singh Gaurav , Mishra Madan , Gaur Amit
Published: July 2023

Ameloblastoma is characteristically considered to be a benign but locally aggressive and infiltrative odontogenic tumor with a high recurrence rate. Because of its locally invasive nature, the recurrence rates for the ameloblastoma post treatment remains high. Recurrence also seems to depend on the histological type of the tumor and the treatment modalities used. Curettage alone is reported to have led to a 90% recurrence rate for mandibular tumors and a 100% recurrence rate for maxillary tumors in literature. In a sample of 327 cases in a large study, a 17.7% recurrence rate was noted after radical treatment and a rate of 22.6% was noted after conservative treatment; granular and follicular variants of ameloblastomas were seen to recur more frequently than the plexiform type. Most recurrences occur at the site of the primary tumor. However, lesions are also known to recur in bone grafts, and rarely, recurrence involves adjacent soft tissues. In this study, we present an unusual case of a plexiform ameloblastoma that recurred in the left mandibular residual soft tissue 8 years after the first surgery i.e. disarticulating hemimandibulectomy. The patient is on regular follow up post second surgery for 23 months and she has been symptom free till now.

Dentаl-аnchоred Hyrаx deviсe wаs usеd tо bring аbоut the distаctiоn tо incrеаse the uрреr jаw length withоut аltering spеeсh, with аdеquаte аnd stаble occlusiоn. Dental implants were placed in a recently created bone to replace missing teeth.

For patients with maxillary hypoplasia, AMSD is a successful treatment option. It preserves velорhаryngeal function and is a stаble therаpy that keeps the overjet achieved with distraction osteogenesis without damaging the posterior occlusiоn. During the consolidation phase, intermаxillary elаstiсs can solve the open bite caused by tooth-borne devices. At a reasonable cost, the mоdified Hyrаx system allows the maxillary arch to be extended and pushed forward.

Authors: Garg Kamal
Published: July 2023

Background: Serum C-reactive protein (CRP) is non-specific in nature and is seen to be associated with adverse pregnancy outcomes. Thus we aim to compare serum CRP levels in pregnant women with and without periodontitis. 

Methods: A total of 222 pregnant women aged between 18-45 years were recruited in study and divided into two groups Group A:- Pregnant patient without periodontitis (n=100) and Group B:- Pregnant patient with periodontitis (n=122). Different clinical parameters such as plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment loss (CAL) were evaluated. A 2 ml of blood sample was taken from antecubital vein for quantative serum CRP analysis.

Results: The mean CRP level in Group B was found to be higher (4.22 + 2.247 mg/L) than Group A (1.55 + 0.702 mg/L). In both the groups, statistically significant and positive correlation of PI with GI and CRP level was found (p < 0.05). Similarly, in Group B, PI showed a positive correlation with PD & CAL whereas, PD showed a similar correlation with CAL & CRP level was statistically significant. (p < 0.05).

Conclusion: Periodontitis influenced the serum CRP levels in pregnant patients representing increased inflammatory burden.

'Repair the defect' - Emerging topical fluoridated remineralizing agents : A review
Authors: Singh Monika
Published: July 2023

A universal public health issue that affects 60% to 90% of people worldwide is dental caries, especially in youngsters. Dental caries is a cyclical event with phases of demineralization and remineralization in addition to being a continuous and unidirectional process of the demineralization of the mineral. Cavitation results from an overbalance in the demineralization process. While remineralization is the process of increasing ion deposition into crystal gaps in demineralized enamel to achieve net mineral gain, it is defined as the supply of calcium and phosphate ions from a source external to the tooth surface. Despite the fact that many other therapies have been tried in recent years to treat early enamel carious lesions, fluorides have emerged as the most popular remineralizing agent due to their superior cariostatic efficacy and affordability. Alternative preparations with additional benefits would be of interest because currently available topical fluorides require patient participation and several treatments over the course of a year.

Abstract-

Background- Color is the important property for the restorative materials to have long-term durability in the oral cavity. Color is important in aesthetics, characterizing and personalizing a smile.

Aim- The aim of this study was to evaluate the effects of five commercially available mouthrinses (Listerine, Colgate plax, Clohex Plus, Orahex Plus and Senquel-AD) on color stability of three different resin-based composite restorative materials.

Material and Methods - A custom made stainless steel split mold was used for fabrication of  forty-eight samples of each composite resin material (Durafill VS, Z100, Filtek Z350 XT). The samples were immersed in distilled water after curing for 24 hours. Baseline measurements for Color stability were taken. After that, each group was immersed in 20 ml of assigned mouthrinse solutions and incubated at 37° C for 24 hours. The samples were resubjected to Color stability tests. The change in color difference was calculated.

Statistical analysis-

Result- The results revealed that all mouthrinses tested changed the color of the composite resins.

Conclusions- It may be concluded that the effect was both mouthrinse and material dependent.

Peripheral giant cell granuloma (PGCG) is tumor like, non-neoplastic reactive intra-osseous lesion occurring in the gingiva or alveolar mucosa and is characterized by an un-encapsulated proliferation of mononuclear polygonal cells which are spindle-shaped with osteoclast-type multinucleated giant cells in a vascular background. This is a case report of 28 year old female with peripheral giant cell granuloma in mandibular anterior region. The lesion was completely excised to the periosteum level and no recurrence was seen in 1 month follow up.
Simplify your practice with 3D printed space maintainer
Authors: Pahuja Naman
Published: July 2023

Preventive orthodontics is an aspect of pediatric dentistry, which requires exclusive set of skills and understanding to aid the patient’s treatment and properly align teeth. The safest way to prevent future malocclusions from tooth loss is to place a space maintainer (SM), which is advocated to embrace the space until the eruption of succedaneous permanent teeth. SM manufacturing is a painstaking process that requires plentiful communication with the laboratory to suitably complete and provide the patient with optimal results. Band and loop SM is mostly indicated for the premature loss of single primary molar, but this appliance has a number of limitations. Digital technology has resulted in decreasing human errors by automating the dental model fabricating process with three‑dimensional printing. The current paper provides an insight of the use of this new technology in pediatric dentistry for manufacturing of new type of SMs and a case report
A case study of peripheral ossifying fibroma
Authors: Bhatnagar Parkhi , Tripathy Santwana
Published: July 2023

The gingiva is frequently the site of localised growths that are thought to be reactive rather than neoplastic. Many of these lesions are difficult to identify clinically and can only be identified as a distinct entity based on typical and consistent histomorphology. One such reactive lesion is peripheral ossifying fibroma. It has been described using various synonyms and is thought to arise from the periodontal ligament, which accounts for approximately 9% of all gingival growths. The lesion is typically small in size, located primarily in the anterior maxilla, with a higher predilection for females, and is more common in the second decade of life. A 11-year-old boy with a large peripheral ossifying fibroma in the anterior maxilla with significant growth and interference with occlusion is presented in this case report.

A large number of luting agents (dental cements) are available and proper selection can be a daunting task and is usually based on a practitioner’s reliance, on their experience and preference. The literature continues to repeat that ‘‘No available product satisfies the requirements for an ideal luting agent and comprehensive patient care requires several materials…. the best choice is not always easy’’. Ceramic restoration in the form of indirect crowns and fixed partial dentures form the mainstay of oral rehabilitations.  However, their use has made luting procedures more challenging. The aim of cementation is to integrate the restorations with the dental hard tissues, especially with the dentin, supplying retention, marginal sealing, and esthetics. Zirconia FPDs can be luted with conventional cements (zinc phosphate cement and glass ionomer) but they show high solubility and low mechanical resistance in the presence of bioactivity and fluoride release. Commonly used resin luting agents are sensitive to moisture, undergo dimensional changes (polymerization and thermal), show minimum bacterial resistance, and lack dentin remineralization potential, fail to create a natural chemical bond to dentin and lack bioactivity to prevent microleakage. It is proposed that contemporary bioactive esthetic materials have the potential to reduce bacterial microleakage and enhance marginal integrity by showing recharge and renewal of restorative material constituents. The purpose of this article is to review various luting agents, their properties & associated clinical implications and to help the clinician to select an appropriate luting agent for a given clinical situation.

Facial and object recognition are more and more applied in our life. Therefore, this field has become important to both academicians and practitioners. Face recognition systems are complex systems using features of the face to recognize. Current face recognition systems may be used to increase work efficiency in various methods, including smart homes, online banking, traffic, sports, robots, and others. With various applications like this, the number of facial recognition methods has been increasing in recent years. However, the performance of face recognition systems can be significantly affected by various factors such as lighting conditions, and different types of masks (sunglasses, scarves, hats, etc.). In this paper, a detailed comparison between face recognition techniques is exposed by listing the structure of each model, the advantages and disadvantages as well as performing experiments to demonstrate the robustness, accuracy, and complexity of each algorithm. To be detailed, let’s give a performance comparison of three methods for measuring the efficacy of face recognition systems including a support vector machine (SVM), a visual geometry group with 16 layers (VGG-16), and a residual network with 50 layers (ResNet-50) in real-life settings. The efficiency of algorithms is evaluated in various environments such as normal light indoors, backlit indoors, low light indoors, natural light outdoors, and backlit outdoors. In addition, this paper also evaluates faces with hats and glasses to examine the accuracy of the methods. The experimental results indicate that the ResNet-50 has the highest accuracy to identify faces. The time to recognize is ranging from 1.1s to 1.2s in the normal environment

Tin oxide (SnO2) semiconductor is recognized as a highly promising material for the electron transport layer (ETL) in perovskite solar cells (PSC) due to their wide band gap energy and high electron mobility. This material has been considered as the potential alternative material for substituting the conventional titanium dioxide (TiO2). In the form of nanostructure material, it is expected that SnO2 as the ETL in PSC device can be significantly improved owing to its high surface area leading to more intensive photon absorption. In this present study, SnO2 nanoparticles were synthesized via the hydrothermal method with temperature variations ranging from 120 °C to 160 °C for 16 hours. The as-synthesized samples were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), and an ultraviolet–visible (UV-Vis) spectrophotometer. The SnO2 nanoparticles were then integrated into the PSC device as the ETL, and the performance testing was conducted using a semiconductor parameter analyzer to obtain the I-V curve. On the basis of investigation results, it has been found that the temperature used during the hydrothermal process plays a crucial role in determining the crystallinity, morphology, and band gap energy of the SnO2 nanoparticles. The results of the PSC performance test indicate that SnO2 nanoparticles synthesized at a hydrothermal temperature of 150 °C demonstrated the highest power conversion efficiency (PCE) of 3.89 %. This outcome confirms the viability of SnO2 nanoparticles produced through the hydrothermal method

Introduction. The study of the mechanisms of adaptation and consequences of deadaptation in newborns, and especially premature babies in the first days of life is an integral part of neonatal practice. The cytokine system is considered as sensitive and informative indicators of homeostatic disorders in newborns of different gestational ages.

Aim. To assess the features of the early neonatal period in newborns of different gestational ages according to the nature of changes in the levels of interleukin-1, -4, -8 in the cord blood and on the 3-4th day of the infant's life.

Materials and methods. 108 newborns were examined, of which 64 premature infants of the gestational age of 32 (0/7) - 36 (6/7) weeks were included in the treatment group: moderately premature infants (32 (0/7) - 33 (6/7) weeks) and late premature infants (34 (0/7) - 36 (6/7) weeks). The control group included 44 conditionally healthy full-term infants born between 37 (0/7) and 41 (6/7) week of gestation: early full-term (37 (0/7) - 38 (6/7) weeks) and full-term intants (more than 39 (0/7) weeks).

Results and discussion. The full-term infants, as well as late premature infants, whose clinical status was assessed as satisfactory, usually showed minimum levels of all studied cytokines. If the early neonatal period was complicated, high levels of interleukin-1 and -8 with underlying slightly elevated levels of anti-inflammatory interleukin-4 were observed. This fact supports the activation of cytokine reactions during manifestation of pathological symptom groups generated by various organs and systems in the early neonatal period.

Conclusion. The nature of cytokine reactions can serve as a marker of unfavourable course of the early neonatal period in premature infants and a criterion that justifies the implementation of necessary corrective measures.

This article discusses the use of antibacterial therapy in the treatment of acute rhinosinusitis in children. The main problems causing the need for maximum rationalization of the use of systemic antibiotics in the treatment of respiratory pathology are listed. Indications for systemic and topical antibacterial therapy for acute rhinosinusitis in children indicated in Russian clinical guidelines were noted. The possibilities of using the combined drug thiamphenicol and N-acetylcysteine in the treatment of acute rhinosinusitis in children are considered separately. As an example, a model of the clinical situation at the outpatient stage of treatment, in which the use of inhalation therapy is advisable, is given. It is concluded that inhalation therapy with a combination drug of thiamphenicol and N-acetylcysteine in the treatment of acute rhinosinusitis is a reasonable choice in case the doctor doubts the need for systemic antibacterial therapy. Taking into account the high frequency of such situations in the practice of a pediatrician and a pediatric otorhinolaryngologist, the decision in favor of topical antibacterial therapy carries significantly less costs compared to the decision to prescribe systemic antibacterial therapy. But an obligatory element of the therapeutic tactics of acute rhinosinusitis with the use of topical antibacterial drugs should be monitoring the dynamics of the patient's condition during 3-4 days of therapy. In the absence of positive changes, the doctor is obliged to reconsider the need for systemic antibacterial therapy.
