Published: July 2023

The world's covid-19 pandemic has affected many things including social and economic activities. Many boundaries of the country have to be closed in response to the spread of this dangerous outbreak. For Muslims, one of the main effects is the obstacle to performing Umrah and Hajj where Saudi Arabia is among the countries that close their country's borders from the influx of pilgrims and pilgrims. However, after many countries began to show a decline in the outbreak of the outbreak either through the vaccination and various other efforts, Saudi Arabia has begun to open their country's borders for other countries to perform the pilgrimage and umrah. This study was conducted to evaluate the response of the people in the northern states of Peninsular Malaysia to the ability to perform Umrah worship during the Covid-19 endemic phase. The main focus of the study involves the people of two states in the north of Malaysia, Kedah and Perlis. The quantitative research methodology was used where 1093 responses were collected from both states. The study population is 2 million Muslims. This study is important to evaluate the tendency of the people in both states on their intention to perform Umrah and Hajj as the situation improves. It was found that the response from the people of both states was very good and very positive. They show strong interest and willingness to perform Umrah worship such as previous years.

Published: July 2023

The purpose of this paper is to examine the readiness on online learning during COVID-19 pandemic based on the conceptual frameworks adapted from Stauffer (2020), Butnaru et al. (2021), and (John Lemay et al., 2021). It is mainly quantitative in nature alongside some quantitative data. It examines the students’ readiness of shifting from the face-to-face teaching and learning to online learning. They are also asked to provide their experience of accessing online learning. The research data was collected at a local university in Malaysia through a survey comprises 71 student respondents and an interview with 10 student interviewees. The results of the research show that i) the students were exceled in computer skills but unfamiliar to the online platform; ii) students were satisfied with the internet network support quality; iii) few students used mono type online device to access online learning; iv) students did not have previous experience on online learning during high school and the students felt anxious before and during accessing online learning. The findings further reveal that the internet network support provided in the country is the factor of some students unable to access the online learning smoothly, they used more than one type of online device to access the online learning and felt anxiety on the disconnection of internet might affect their performance in assessments and presentation evaluation. The telcos are suggested to accelerate the upgrade of their internet network support quality in order to facilitate the success of the National 4IR policy in the country.

Authors: Zahedieh Saba , Md Sarkan Haslina , Kama Mohd Nazri , Mohd Rusli Hazlifah , Yahya Yazriwati
Published: July 2023

Various factors including increasing energy prices, government policies, and environmental concerns are driving the energy transition. Electric vehicles (EVs) have the potential to contribute to the sustainable energy transition as they can reduce fossil fuel dependence. This study provides a comparative analysis of the existing charging station deployment models concerning their performance and the current major barriers to their adoption in Malaysia. Electric Vehicle (EV) Service Providers and Networks are established to provide charging facilities for EVs. However, the business model and method of identifying users has formed a group of closed networks, which are operating in isolation. The isolation of these networks will prevent Electric Vehicle Owner (EVO) from charging their EVs even if a charging station is available. This will cause range anxiety and affects general acceptance of EVs. The proposed concept intends to overcome this issue by implementing a new cloud-based software system which is called Malaysian Electric Vehicle Central Management System, MEV-CMS. It provides authentication communication between any non-subscribed Service Providers (SP) and the subscribed SP of the EV ecosystem in Malaysia. This paper discusses the initiating practices and requirements gathering carried out to develop the central management system. The system requirements were gathered from exposition visits, industry collaborations as well as the literature study contributions. The work provides useful insights that can be beneficial for the management of charging stations for EVs in other countries as well.
An Examination of Drill Rig NOx Emission
Authors:   Scholar, Department of Petroleum and Gas Engineering, Delta State University of Science and Technology, Ozoro, Nigeria., Onwuachi-Iheagwara P. N.
Published: July 2023

This article creates awareness of greenhouse gases (GHG). The greenhouse gases play a significant role in climate change. The GHG includes NOx which is N2O, NO, and NO2. NOx can be produced from several human activities, including agricultural practices and drill rigs engine activities. However, drill rig emissions have received limited attention in Nigeria compared to agricultural emissions. This article addresses this research gap by examining the production of NOx emissions from drill rigs in Nigeria and its contributing effects. It also discusses the effects of climate change, which include increases in temperature, rainfall, rising sea levels, and the incidence of flooding. Storm aberrations, shortages of usable land, and potable water accompany this. The study adopts a methodology based on the correlation established by Russell (2006) to derive formation emission factors for onshore, offshore, and deep offshore Nigerian wells. The formation emission factors are based on the number of wells drilled in these locations from 2002 to 2004 and the average depth of wells in these locations. The analysis reveals that while NOx levels in Nigeria are currently low, they exhibit a constant upward trend. This observation is significant for a country heavily reliant on the petroleum industry for foreign exchange earnings and economic stability. Furthermore, considering Nigeria's vulnerability to the impacts of climate change and associated hazards, understanding the effect of drill rig NOx emissions and its production becomes crucial. By shedding light on this overlooked aspect, this research contributes to a more comprehensive understanding of the environmental implications and sustainable practices in Nigeria's petroleum sector.

Published: July 2023

Background. The treatment of pulp inflammation takes an important place among modern dentistry problems. Depulpated teeth in some cases become chronic source of infection. They could also cause an odontogenic infection of the maxillofacial region. In this regard, it is important to use conservative methods of treatment to eliminate the inflammatory process in the dental pulp and preserve the vitality of the tooth.

Aim. The aim of this study is to collect and systematize the information about modern aspects of the conservative treatment of pulp hyperemia that is presented in scientific articles and to study the effects and impacts of bioactive materials on pulp tissues.

Materials and methods. A search was made for literature sources in the database: PubMed, dissercat.com, elibrary.ru, cyberleninka.ru using the keywords «caries», «pulp hyperemia», «pulpitis», «bioactive materials» with a choice of article types «Clinical Trial», «Meta-Analysis», «Review», «Systematic Review».

Results. After analyzing the literature review, an idea was obtained about the pathogenesis of the pulp at various stages of inflammation, criteria for its clinical assessment of the morphological state, pathophysiological and cytological processes of the pulp when exposed to bioactive materials. A modern classification and review of bioactive materials used in the treatment of pulp hyperemia is presented.

Conclusions. Studying the literature on the morphology and pathophysiology of the pulp, on its reserve possibilities of the regeneration plan, it was found that the inflammation in the dental pulp is reversible. This requires modern therapeutic materials that cause the reverse development of inflammation in the dental pulp. A conservative method of treating pulp hyperemia involves using materials that restore the structural and functional properties of the pulp, so preserve its vitality. This review article provides an overview of the materials used in the conservative treatment of pulp hyperemia according to Russian and foreign literature.

Published: July 2023

One of the non-invasive methods for assessing oxidative stress is the study of the oral fluid of patients by chemiluminescence. Based on the data obtained, it is possible to quantify the degree of oxidative stress and adjust the prescribed therapy.

Objectives. To assess the state of free radical oxidation of the oral fluid by chemiluminescence (CL) in patients with various verified forms of oral lichen planus (OLP), compare the data obtained with those in the control group.

Materials and methods. 287 patients with various forms of OLP of the oral mucosa and 32 patients of the control group, comparable in sex and age, were studied. The assessment of oxidative stress was carried out using the device HL-003, examining the oral fluid.

Results. The parameters S, Imax of individual forms of OLP had statistically significant differences compared with those of the control group of patients. Thus, the erosive-ulcerative form of OLP by the S parameter exceeded the conditional norm by 2.45 times, by the Imax parameter it exceeded by 2.37 times; exudative-hyperemic form exceeded the norm in parameter S, exceeded the conditional norm by 2.12 times, in parameter Imax exceeded 1.71 times; atypical form of OLP had a statistically significant excess in Imax by 1.49 times; the bullous form of OLP had a statistically significant excess in the S parameter by 2.18 times. Other forms of OLP (typical, hyperkeratotic) did not have statistically sign100ificant differences in the parameters S, Imax.

Conclusions. The obtained data substantiate the inclusion of antioxidant therapy in the ongoing OLP therapy; indicators of CL in the oral fluid can be one of the biomarkers in the diagnosis and monitoring of therapy in OLP, especially in the long term, mainly in erosive-ulcerative, exudative-hyperemic, atypical and bullous forms of OLP.

Published: July 2023

Aim. With the help of pathomorphological studies, to study dystrophic changes that occur in teeth with destructive forms of periodontitis in the acute stage and in the tissues surrounding them.

Materials and methods. For morphological study, biopsies of 48 teeth and periapical foci of infection of destructive forms of apical periodontitis in the acute stage were used. The material processed according to generally accepted methods was studied using an Olympus BX-40 light microscope.

Results. Dystrophic changes were observed in 9 out of 48 studied teeth, which amounted to 18.75 %. Various manifestations of dystrophy testified to pathomorphological changes in tissues during the chronic course of the disease.

Conclusions. Exacerbation of the inflammatory process in destructive periodontitis is accompanied by an autoimmune response of the body. Calcifications indicate changes in tissues. Dystrophy leads to total necrosis of pulp and periodontal tissues. Tissue granulomas with signs of dystrophy, chronic inflammatory process. Accumulation in the tissues of dental granulomas during the period of exacerbation of GAG is uneven, mostly of low and moderate intensity with a predominance of non-sulfated compounds. The body on its own is not able to cope with a long-standing inflammatory process.

Authors: Glass Jorge Alan , Anguera Maria das Graças
Published: July 2023

A utilização regular de mochilas, frequentemente pesadas, por conta dos materiais necessários para o dia escolar apresenta uma variedade de riscos, principalmente durante o período de crescimento e especialmente na adolescência. Alguns estudos sobre a saúde destacam que as alterações posturais e as dores nas costas de escolares de 10 a 15 anos, são causadas pelo excesso de peso em suas mochilas. Nesse sentido, o objetivo do estudo foi averiguar se o peso das mochilas utilizadas por escolares entre 10 e 15 anos de uma Escola Pública do Paraná está adequado, aceitável ou inadequado de acordo com sua massa corporal, sugerido pela comunidade científica e estabelecido na Lei 17.482/2013. A verificação da adequação do peso da mochila em relação à massa corporal foi feita de acordo com dois parâmetros: um utilizando as classificações sugeridas pela comunidade científica: adequado (≤10% do peso corporal do sujeito);  aceitável (≤15% do peso corporal do sujeito); inadequado (˃15% do peso corporal do sujeito) e o outro parâmetro utilizando as classificações sugeridas pela Lei 17.482/2013: adequado (≤10% do peso corporal do indivíduo) e inadequado (˃10% do peso corporal do indivíduo). Os resultados desse estudo demonstraram que quando feitas as médias agrupadas pela faixa etária, nenhum dos grupos esteve inadequado conforme os parâmetros da literatura que é de até 15% de peso transportado da massa corporal, porém, conforme a Lei 17.482/2013, quatro dos seis grupos etários estiveram inadequados, sendo eles de 10, 11, 12 e 14 anos. Finalmente, existe uma diferença bem significativa, quando comparamos as duas referências de análises, pois, avaliando o resultado da proposta dos autores, a maioria dos pesos das mochilas investigadas se encontra nos padrões adequado e aceitável, que juntos representam quase 90% da amostra, e quando analisado os resultados a partir da Lei 17.482, prevalece o padrão inadequado.

Ameloblastoma accounts for 10% of living tumors of odontogenic origin. Ameloblastoma has an epithelial origin, more commonly occurring in the jaw bone. As much as it is a benign tumor, ameloblastoma tends to be invasive and aggressive, making total tumor resection with a safe margin, with the aim of to prevent future recurrences. This tumor has its own clinical and radiographic aspects, being able to be found in its primordial stage of expansion . The ameloblastoma lesion maintains several alterations in its clinical signs, which may manifest periods of tumor aggressiveness. Its cause is uncertain, so it appears in a variety of ways.

Authors: Mohan S. , Vimala P.
Published: July 2023

Mobile Ad hoc Networks (MANETs) offer numerous benefits and have been used in different applications. MANETs are dynamic peer-to-peer networks that use multi-hop data transfer without the need forpre-existing infrastructure. Due to their nature, for secure communication of mobile nodes, they need unique security requirements in MANET. In this work, a Hybrid Firefly Cyclic Rider Optimization (FCRO) algorithm is proposed for Cluster Head selection, it efficiently selects the cluster head and improves the network efficiency. The Ridge Regression Classification algorithm is presented in this work to detect the malicious nodes in the network and the data is transmitted using trusted Mobile nodes for the QoS performance metric improvement. A trust-based routing protocol is introduced using the Atom Emperor Penguin Optimization (AEPO) algorithm, it identifies the best-forwarded path to moderate the routing overhead problem in MANET. The proposed method is implemented using Matlab software and the performance metrics are packet delivers ratio, packet loss ratio, routing overhead, throughput, end-to-end delay, transmission delay, network lifetime, and energy consumption. The proposed AEPO algorithm is compared with the existing PSO-GA, TID-CMGR, and MFFA. The AEPO algorithm’s performance is approximately 1.5%, 3.2%, 2%, 3%, and 4% higher than the existing methods for packet delivers ratio, packet loss ratio, end-to-end delay, and throughput and network lifetime. This evaluation enables the sender nodes to improve their data transmission rates and minimizes the delay. Additionally, the suggested technique has a clear benefit in terms of demonstrating the genuine contribution of distinct nodes to trust evaluation.

Authors: Zagorskaya S. G.
Published: July 2023

Russia holds the first largest collection of canvas by great Spanish masters outside of Spain, including paintings by El Greco, Murillo, Ribera, Zurbaran, Goya, and others. In November 2023 the Pushkin State Museum of Fine Arts presents an exhibition of Spanish paintings from its own collections, as well as the works of art from the Hermitage and regional museums. In this interview, Svetlana Zagorskaya, curator of Spanish painting at the Pushkin Museum, talks about the collections of Spanish painting in Russia, the history of their acquisition and meticulous work of attributing paintings. Particular attention is paid to Svetlana Zagorskaya’s discoveries of the authorship of the canvas by Jusepe de Ribera «Saint James the Greater» and the painting by Bartolomeo Murillo «Saint Catherine of Alexandria», which open the exposition of old masters in the main building of the Museum. The purpose of the upcoming exhibition, apart from being educational, is to show the cultural attraction of Spain and Russia, two countries at the extreme ends of Europe. Since the end of the 19th century many Russian artists visited Spain and looked for new motives for inspiration, at the same time Russian collectors bought a lot of works by Spanish artists. Thus, an invisible but strong cultural bridge was being built between the two countries, and it still exists in our time.

Authors: Becerra Ramírez Sebastián , Forero Sanabria Cheryle
Published: July 2023

Mediante el desarrollo de este trabajo, se busca establecer el impacto de la Inversión extranjera directa (IED) sobre el Producto interno bruto (PIB), la formación bruta de capital (FBK) y la tasa de ocupación laboral (TOC) como determinantes del crecimiento económico de México durante el periodo de 1960-2021. Se empleó una metodología cuantitativa descriptiva, para la cual se hizo uso de herramientas estadísticas que permitieron distinguir las características de las variables, determinar los grados de asociación y evaluar su comportamiento a lo largo del tiempo. Los principales resultados indican que los aumentos en los flujos de la IED propician incrementos en el PIB y en la FBK. De otra forma, no se encontró una relación significativa entre la IED y la TOC, ya que aumentos en la IED no generan impactos en la empleabilidad. Con base a lo anterior, el articulo sugiere la implantación de políticas dirigidas a erradicar los sesgos existentes en los sectores de la economía de México, con el objeto de dinamizar los flujos de IED.
Lipid profile in patients with leiomyoma-A case-control study
Authors: Prasad H.L. Kishan , Dasan Nimmy Maria , Kishan Ashwini , Kumari N. Suchetha
Published: July 2023

Introduction and Aim:  The most frequent gynaecological neoplasm in women of reproductive age is leiomyoma (Fibroid). They are hormone-dependent tumours, and estrogen will promote their development. It has been found that estrogen levels and cholesterol levels are inversely associated.  Few studies have shown no relation between lipid profile and leiomyoma, but few studies suggested a positive correlation. The lipid profile of patients with uterine fibroids (the case group) and women without fibroids (the control group) is compared in the current study.
 
Materials and Methods: The case-control study included fifty subjects between 20 to 40 years. Twenty-five serum samples collected from women without evidence of leiomyoma were considered the control group. Twenty-five cases were admitted with various symptoms, diagnosed and confirmed as leiomyoma on histopathology.
 
Results: There was a substantial difference in Total Cholesterol (TC) and Low-Density Lipoprotein cholesterol (LDL-C) levels between patients with leiomyoma and healthy people.  With a p-value of 0.04, the TC, LDL-C level in leiomyoma patients was substantially lower than that of healthy individuals in the general population. The levels of triglycerides, High-Density Lipoprotein cholesterol (HDL-C), and Very Low-Density Lipoprotein cholesterol (VLDL-C) were comparable across the case and control groups, though.
 
Conclusion: According to the study's findings, patients with leiomyoma have lower serum TC and LDL-C levels than healthy controls. This could be linked to patients with leiomyomas having higher estrogen levels. As a result, lipid profile variables like TC and LDL-C may be accurate indicators of leiomyoma. These findings point to the possibility of blood plasma lipid profiling for the non-invasive diagnosis of fibroids.

Published: July 2023

Introduction and Aim: Cervicofacial actinomycosis is a rare chronic granulomatous disease caused by Actinomyces and is the commonest subtype of actinomycosis. Due to the similarities in clinical presentation, cervicofacial actinomycosis is almost always suspected as malignancy or tuberculosis. Histopathological evaluation is crucial in diagnosis and management of these cases. The aim of the study was to evaluate the clinicopathological features of cervicofacial actinomycosis in the biopsy specimens.
 
Methodology: This is a retrospective cross sectional observational study of 17 years duration. All cases of cervicofacial actinomycosis diagnosed on biopsy specimens were analyzed. Clinical presentations and histomorphological features were evaluated on hematoxylin and eosin-stained slides with confirmation of organism on special stains.
 
Results:  Out of 36 diagnosed cases of actinomycosis during the study period, we evaluated 16 cases (44.4%) of cervicofacial actinomycosis. Mean age of presentation was 38 years. Male to female ratio was 1:0.9. The anatomical sites of eight (50%) were in the oral cavity, six (37.5%) on the face and two (12.5%) in the neck. Two cases (12.5%) had sinuses discharging sulphur granules. Six cases (37.5%) were clinically suspected as malignant and among them two cases (12.5%) also had differential diagnosis of tuberculosis. All cases on histomorphology showed sulphur granules consisting of basophilic filamentous bacterial colonies with Splendore Hoeppli phenomenon and mixed inflammation. On special stains, the bacterial colonies were Gram, PAS and GMS stain positive, and acid fast negative.
 
Conclusion: Cervicofacial actinomycosis are uncommon. Their presentation can mimic carcinoma or tuberculosis. Consistent histomorphological features can direct towards identification of organisms by special stains for confirmation of diagnosis.
Efficacy of microcurrent therapy versus laser therapy for diabetic foot ulcer on size of the wound
Authors: M. Kamalakannan , S. Chitra , V. Shruthi Kamal
Published: July 2023

Introduction and Aim: Diabetes mellitus (DM) will increasingly contribute to years of life and disability worldwide. Approximately 25% of individuals with diabetes will develop diabetic foot ulcers. This study aimed to assess the effectiveness of microcurrent therapy compared to low-level laser therapy in terms of wound healing and quality of life among patients with diabetic foot ulcers.
 
Materials and Methods: This study followed a prospective randomized open blinded endpoint assessment (PROBE) design with two parallel groups allocated in a 1:1 ratio. Participants meeting the selection criteria and having diabetic foot ulcers were included. Baseline measurements were taken before randomly assigning participants to the treatment groups. Pre-test and post-test data were collected to evaluate the wound size.
 
Results: The t-test analyses demonstrated significant improvement in both treatment groups (LLLT: t = 41.818, p < 0.001; Micro-Current Group: t = 32.787, p < 0.001). To compare the groups, One-Way Analysis of Variance (ANOVA) was conducted, indicating a significant difference in ulcer size between the LLLT group (mean value: 62.600, SD=3.035) and the microcurrent therapy group (mean value: 51.933, SD= 6.938).
 
Conclusion: This study concludes that microcurrent therapy is more effective than low-level laser therapy for managing diabetic foot ulcers. The findings suggest that a 3-week intensive physiotherapy therapeutic approach, combined with conventional medical treatment, yields the best results in terms of wound healing.
A novel conservative modality in the management of internal derangement of temporomandibular joint- A case report
Authors: Ravikumar Chandini , V.B. Krishnakumar Raja , B. Sasikala
Published: July 2023

Temporomandibular joint internal derangement (TMJ ID) may be managed by conservative means, minimally invasive methods, and/ or surgically. Conservative options include soft diet, pharmacotherapy, splints, physiotherapy, or topical administration of nutraceuticals, for elimination of TMJ ID symptoms. FIXIT is a topical ointment, consisting of plant-based ingredients; its specific components have been successful in treating knee osteoarthritis (OA). However, these have not been applied for TMJ ID conditions (lacuna in literature). The aim of this study is, therefore, to evaluate the effectiveness of FIXIT in TMJ ID management by assessing TMJ pain, clicking sound and pain-free maximum mouth opening (MMO) in an 18-year-old male. The patient complained of right TMJ pain (VAS- 8) on mouth opening, and loud clicking sounds, with pain-free MMO of 19 mm pre-treatment. Post-topical therapy (after 3 weeks) with FIXIT, significant reduction in TMJ pain (VAS- 0) and joint sounds (absent- 0), with improved MMO (47 mm) was noted. No recurrence of symptoms was observed after 3 months of follow-up. FIXIT has been effective in alleviating TMJ ID symptoms, thereby enhancing overall jaw function. Its ability to eliminate clicking sounds was found to be an unprecedented finding; suggesting it’ novelty as a non-surgical intervention for TMJ ID.

Published: July 2023

Introduction and Aim: Klebsiella pneumoniae is a Gram-negative bacterium responsible for a wide range of infections, including respiratory tract infections (RTIs). This research was aimed to study the antibacterial and anti-biofilm effect of AgNPs produced by Gram positive and negative bacteria on RTIs associated with K. pneumoniae.
 
Materials and Methods: The biofilm formation of K.  pneumoniae was determined by tube method qualitatively from select bacterial species characterized by UV-Visible spectroscopy. The antibacterial susceptibility of the bacteria AgNPs was tested for their antibacterial and antibiofilm activity on a clinical isolate of K. pneumoniae.
 
Results: K. pneumoniae isolated from RTIs were strong biofilm producers.  The antibacterial activity of AgNPs synthesized from bacterial spp in this study had good antibacterial activity against K. pneumoniae. P. aeruginosa and P. mirabilis AgNPs had the strongest anti-biofilm effect, with 84% and 83%, respectively, while A. baumanii's AgNPs had the lowest (79%). AgNPs of P. aeruginosa and P. luteola showed the highest (80%) anti-biofilm action against the development of pre- and post-mature biofilms formed by K. pneumoniae, while AgNPs from S. mitis exhibited the lowest levels (69%).
 
Conclusion: AgNPs generated by Gram positive and Gram-negative bacteria, when exposed to K. pneumoniae isolated from RTIs had a good antibacterial impact and inhibited the formation of biofilm by K. pneumonia and hence could be used as an antibacterial agent against K. pneumoniae infecting the respiratory tract.

Published: July 2023

Patients with Cardiovascular diseases (CVDs) frequently suffer from physical and psychological complications, while providing informal care for patients is a difficult and time-consuming task that necessitates time, dedication, and perseverance. Contemporary studies addressing health quality of life in relation to CVDs have traditionally focused on the individual who has the illness or condition rather than that of the caregivers. The study addresses this limitation, with a view of providing empirical evidences of Health Related Quality of Life (HRQL) of CVDs patient caregivers in the study area. The outcome variable was HQRL and the independent variable was psychological distress. The HQRL was captured as psychological physical functioning, mental functioning, dimension support and physical outlook. The study employed both descriptive survey and the experimental designs. The study was a hospital-based cross sectional approach. The study adopted a multi-stage sampling technique, and it sampled quantitative data from eighty-four (n=84) CVDs patient caregivers in Obafemi Awolowo University Teaching Hospital (OAUTH) complex, Ile-Ife, Nigeria. Statistical analysis of data was performed using the IBM SPSS version 25, with the level of significance put at .05. Results of the descriptive analysis showed that 40.5% (n=34) of the caregivers had severe /poor level of HRQL. Results of the regression analysis showed that psychological physical functioning (β = 0.31, t=2.10 p<.05), mental functioning (β = 0.30, t=211 p<.05) and dimension support (β = 0.35, t=2.15 p<.05) were significantly associated with psychological distress. The study concluded that psychological distress had a significant predictive role on HRQL among CVDs patient caregivers.

This research aims to conduct a comprehensive analysis of PT. United Tractors, Tbk shares using a top-down approach, which includes macroeconomic analysis, industry analysis, and company analysis. Additionally, the study aims to determine the intrinsic value of the shares through the Relative Valuation Techniques method and provide suitable recommendations for investors regarding whether to buy, hold, or sell the company's shares. The macroeconomic analysis revealed fluctuations in indicators such as Gross Domestic Product (GDP), inflation, interest rates, money supply, and exchange rate growth. Meanwhile, the industry analysis identified strong competition among similar companies as the dominant force in the market. The threat of new entrants also poses a challenge, especially when competitors target the same market segment. Additionally, the power of suppliers is higher when the number of suppliers is limited compared to the proportion of buyers. Barriers arise when consumers encounter cheaper substitute products. Moreover, the company analysis showcased varying trends in financial ratios such as RTR, FAT, TATO, CR, QR, DER, DAR, GPM, OPM, NPM, ROA, ROS, ROI, EPS, PSR, PER, and PBVR during the period from 2016 to 2021. Furthermore, it was observed that PT. United Tractors, Tbk tends to undervalue its shares by selling them at prices below the intrinsic value. To this end, the study suggests that when the stock market price is lower than the intrinsic value, the shares are undervalued, prompting investors to consider buying. If the stock market price is equal to the intrinsic value, it is fair-valued, and investors are advised to hold. On the other hand, when the stock market price exceeds the intrinsic value, it is overvalued, and investors should consider selling.

Published: July 2023

Este trabalho trata sobre as aplicações na Física de dois conceitos fundamentais da Análise Real: funções lipschitzianas e continuidade uniforme. As principais aplicações investigadas pertencem ao campo da Mecânica Quântica, no estudo das funções e autofunções de onda. Em particular, foi explorado o caso da partícula confinada em um poço finito de potencial quadrado. Foi demonstrando, utilizando a equação de Schrödinger, que a solução deste problema produz um par de autofunções (soluções) que são caracterizadas como lipschitzianas e, portanto, são uniformemente contínuas, donde foi possível extrair uma série de interessantes conclusões.

Published: July 2023

O desinteresse de alunos das novas gerações que hoje ingressam no Ensino Superior é sentido cotidianamente pelos professores. Com relação a esses alunos, denominados nativos digitais, conforme apontam diversos autores, é difícil manter apenas uma estratégia de ensino. Por isso, para o professor faz-se necessário entender as características desses jovens, tentar aproveitar ao máximo as habilidades que já possuem e contribuir para o desenvolvimento de outras. Segundo pesquisas feitas pelo IBGE (2011), 98% dos jovens no Ensino Superior já acessaram a internet. Diante desse contexto, este artigo tem como objetivo discutir as possibilidades de utilização das Tecnologias Digitais da Informação e Comunicação no Ensino Superior como ferramentas para incentivar a autonomia nos estudos de Química e tornar a aprendizagem mais dinâmica, desde que propiciem aos alunos condições de crescimento intelectual e de apropriação crítica dos conteúdos, não os submetendo somente a um pensamento instrumental e operacional. O artigo foi elaborado a partir de estudos teóricos realizados por meio de revisão bibliográfica.
Fotoproteção

A exposição à radiação ultravioleta pode causar danos imediatos e/ou tardios, como hiperpigmentação da derme e até mesmo câncer. A partir disso, a indústria vem aprimorando os recursos disponíveis no que tange à proteção da pele. Os fotoprotetores estão disponíveis sob diferentes formas e preços a fim de atender às necessidades do consumidor, já que a exposição à radiação ultravioleta passou a ser uma questão de saúde pública. As consequências da radiação dependem de vários fatores, como genética do indivíduo, tempo de exposição, entre outros. A UVA é a radiação mais nociva, responsável pelos principais danos em relação à radiação ultravioleta; já a UVC não tem absorção suficiente pela superfície terrestre. Para este estudo foi realizada uma revisão de literatura em artigos científicos no período de agosto de 2004 a dezembro de 2014, os quais foram selecionados nas seguintes bases de dados: Scielo, Bireme e Lilacs. Foram encontrados 16 artigos, todos inseridos neste trabalho. Atualmente, foi derrubado o mito de que a beleza está relacionada ao bronzeamento intencional ou artificial. Segundo autores, no Brasil, por ser um país tropical, o câncer de pele é a consequência de maior gravidade causada pela radiação solar, embora tenha aumentado o conhecimento da população quanto aos tipos de fotoproteção disponíveis no mercado, aos riscos do não uso e ao benefício da exposição ao sol de maneira consciente.

A amoxicilina é um fármaco antimicrobiano de amplo espectro empregado na prática clínica destinada aotratamento de infecções, sobretudo daquelas acometedoras do trato respiratório. As propriedades físico-químicas e biofarmacêuticas da amoxacilina tornam o desenvolvimento de uma preparação farmacêutica com este princípio ativo um grande desafio. Neste sentido, para esta  substância, é necessário considerar como barreiras no processo de desenvolvimento de um novo produto sua restrita solubilidade em meio aquoso, assim como sua susceptibilidade ao processo de hidrólise. Diante dessas considerações, a produção de  comprimidos por via seca demonstra ser uma alternativa interessante para o preparo de comprimidos constituídos de amoxicilina. Além disso, esta via de preparação apresenta inúmeras vantagens sobre o processo produtivo industrial. Portanto, este trabalho teve como objetivo desenvolver comprimidos constituídos de amoxicilina por via seca de compactação e promover ensaios de controle de qualidade destes comprimidos. Para isso, foi proposta uma fórmula farmacêutica empregando-se a amoxicilina em uma dose terapêutica de 500mg, tendo como adjuvantes farmacotécnicos a celulose microcristalina, o estearato de magnésio, a lactose anidra e a croscarmelose sódica. A preparação foi submetida posteriormente a ensaios de controle de qualidade representados por: avaliação de aspecto, peso médio, friabilidade, tempo de desintegração e perfil de dissolução. Foi possível garantir a obtenção de comprimidos constituídos de amoxicilina com perfil de dissolução condizentes com preparações de liberação imediata, bem como a adequabilidade desta diante dos demais ensaios de controle de qualidade.
HOMESCHOOLING E A RELAÇÃO COM A RELIGIÃO
Authors: De Farias David
Published: July 2023

O presente artigo tem a finalidade de analisar a educação domiciliar, chamada de homeschooling, para identificar uma modalidade de educação que é organizada e implementada em domicílio, ou seja, fora do ambiente escolar. Nessa modalidade, a educação não segue os protocolos exigidos na escola, sendo possível uma certa flexibilização da rotina e dos métodos de ensino. Ainda, essa opção é objeto de intenso debate nos últimos anos, principalmente considerando o atual cenário escolar, marcado pela violência, preconceito e intolerância religiosa. Assim, muitos pais optam por não manterem seus filhos em um ambiente marcado pela opressão e violência. Visto isso, o presente estudo tem a finalidade de demonstrar que o homeschooling traz para as crianças maior segurança, conforto e qualidade no aprendizado, uma educação personalizada. Para atingir o objetivo proposto, fez-se um levantamento bibliográfico, com base na busca e seleção de materiais previamente elaborados e publicados, com pertinência ao debate proposto. Concluiu-se que o homeschooling é alternativa apta a proporcionar uma educação de qualidade, em um ambiente alheio às violências, opressões e intolerâncias que marcam, atualmente, o cenário contemporâneo das escolas.
