Published: August 2021

In the last two decades, microfinance institutions across regions have helped to financially build small businesses in areas of disadvantaged populations. The efforts in providing entrepreneurs with small non-collateralized loans (or micro-loans) along with developing cooperative programs for entrepreneurs were reported in earlier studies as being helpful in alleviating some borrowers from extreme economic poverty. However, early warning signals were raised about whether microfinance institutions were benefiting themselves more than the poor. This article assesses the differences in attitudes toward the use of information and communication technology among small business owners in Ghana that have access to micro-loans. The findings indicate significant differences between interest payers and interest non-payers based on region of the country, age, education, and membership in an entrepreneurship program.
How to Manage Incompleteness of Nutritional Food Sources?
Authors: Buche Patrice , Cufi Julien , Dervaux Stéphane , Dibie Juliette , Ibanescu Liliana , Oudot Alrick , Weber Magalie
Published: August 2021

In order to correctly assess the nutritional quality of a raw or manufactured food product, the first step is to obtain the associated nutritional values. Food composition databases (FCDBs) managed at national level provide values for nutrients of foods. Unfortunately, values associated with some nutrients of interest may be lacking in the FCDB of the country in which the nutritional quality must be assessed and finding values associated with nutrients for similar foods in other FCDBs is a way to deal with incompleteness. An additional issue arises because the vocabulary used to denote a given food in a given FCDB is usually different from the one used in others. In this paper, the authors address the problem of retrieving the nutritional value of foods by querying different FCDBs through FoodOn used as pivot ontology. The article presents a new food source alignment method between two FCDBs. The method has been evaluated on the French and United States food nutritional evaluation. The proposed solution for the incompleteness management task has been assessed with a real use case.

Published: August 2021

Bus transportation is the essential mode of public transportation available for intra-district movements in India. The planning of different stages of bus transportation planning is usually done in an ad-hoc manner on the basis of the experience of the operators. For a rational design of the bus transit system, it is essential to take into account the objectives of different interest groups. Selection of an appropriate network structure is an essential part of the planning process. In this paper, a model developed for generating a number of alternative network structures using link deletion concept is presented. One of these alternatives can be selected on the basis of the trade-off between the user and operator objectives. The model has been applied to a case study of bus transit network of Visakhapatnam region in Andhra Pradesh.

Published: August 2021

While optical character recognition for Latin based scripts have seen near human quality performance, the accuracy for the rounded scripts of South Asia still lags behind. Work on Sinhala OCR has mainly reported on performance on constrained classes of font faces and so been inconclusive. This paper provides a comprehensive series of experiments using conventional machine learning as well as deep learning on texts and font faces of diverse types and in diverse resolutions, in order to present a realistic estimation of the complexity of recognizing the rounded script of Sinhala. While texts of both old and contemporary books can be recognized with over 87% accuracy, those in old newspapers are much harder to recognize owing to poor print quality and resolution.

Authors: Belda Jr. Walter , Criado Paulo Ricardo , Casteleti Paula , Domingues Passero Luiz Felipe
Published: August 2021

Chromoblastomycosis (CMB) is a cutaneous fungal infection caused by dematiaceous fungi. According to the World Health Organization CMB has been elected as a tropical disease, and it is prevalent in tropical and subtropical regions. The lower extremities are the most affected areas, and the lesions progress with erythema, papules, nodules, verrucose plates and/or ulcerations. So far, few works have demonstrated neoplastic transformation in chronic CMB lesions, and it may be a consequence of prolonged inflammatory response. In the present case report, we described a neoplastic transformation from CMB lesion of a 55- year-old man, presenting lesions only in the left leg for 35 years. After treatment, a verrucous white plate with thick and irregular borders emerged in the ankle, which was identified as a sarcomatoid squamous cell carcinoma. The present case report highlights the importance of an early diagnosis and treatment.

Published: August 2021

Basal cell carcinoma (BCC) is the most commonly diagnosed cancer in humans, usually affecting elderly Caucasian men and skin regions mostly exposed to the sun, that rarely metastasizes. We report an unusual and aggressive case of multiple, non-syndromic metastatic BCC with an uncommon primary site in the chest and pulmonary metastases, treated successfully with surgery and vismodegib. A 51-year-old woman presented with a large pigmentary lesion of the chest, close to the sternum. She had the lesion for > 25 years and lately noticed multiple facial lesions. The diagnosis of multiple BCC was suspected and a punch biopsy of the primary lesion was performed. Diagnosis was confirmed by immunohistochemistry (BerEp4+, EMA− phenotype). After excision, staging with a thorax computed tomography scan revealed metastatic micro-nodules in the left lung, confirmed histologically after video-assisted thoracic surgical biopsy. Adjuvant chemotherapy with vismodegib was proposed and administered. At 30 days follow-up, thorax computed tomography scan was unaltered and her facial lesions showed significant regression. Although prognosis remains poor, early diagnosis and prompt management complimented by novel biological agents, like vismodegib, targeting disease pathogenesis, seems to bring promising results.

Corticosteroid switching can reverse abiraterone resistance in some patients with metastatic castration-resistant prostate cancer (mCRPC). Here, we investigated the potential biomarkers for predicting the efficacy of corticosteroid switching during treatment with abiraterone acetate (AA). We retrospectively analyzed 101 mCRPC patients receiving corticosteroid switching from West China Hospital and Sun Yat-Sen University Cancer Center between January 2016 and December 2018. All cases received AA plus prednisone as first-line therapy during mCRPC. Primary end points were biochemical progression-free survival (bPFS) and overall survival (OS). The risk groups were defined based on multivariate analysis. A total of 42 (41.6%) and 25 (24.8%) patients achieved 30% and 50% decline in prostate-specific antigen (PSA), respectively, after corticosteroid switching. The median bPFS and median OS on AA plus dexamethasone were 4.9 (95% confidence interval [CI]: 3.7–6.0) months and 18.8 (95% CI: 16.2–30.2) months, respectively. Aldo-keto reductase family 1 member C3 (AKR1C3) expression (hazard ratio [HR]: 2.15, 95% Cl: 1.22–3.80, P = 0.008) and baseline serum alkaline phosphatase (ALP; HR: 4.95, 95% Cl: 2.40–10.19, P < 0.001) were independent predictors of efficacy before corticosteroid switching in the multivariate analysis of bPFS. Only baseline serum ALP >160 IU l−1 (HR: 3.41, 95% Cl: 1.57–7.38, P = 0.002) together with PSA level at switch ≥50 ng ml−1 (HR: 2.59, 95% Cl: 1.22–5.47, P = 0.013) independently predicted poorer OS. Based on the predictive factors in multivariate analysis, we developed two risk stratification tools to select candidates for corticosteroid switching. Detection of serum ALP level, PSA level, and tissue AKR1C3 expression in mCRPC patients could help make clinical decisions for corticosteroid switching.

Authors: Caronan-Parallag Rema G. , Uy Tristan Marvin Z. , Anacleto Francisco E. , Aragon Eric Emmanuel T. , Resontoc Lourdes Paula Real
Published: August 2021

Background:

While steroids have been the standard treatment in nephrotic syndrome (NS), they are known to deleteriously affect bone mineralization.

Objectives:

The objectives were to determine the efficacy and safety of vitamin D supplementation among children with NS on steroid therapy.

Methods:

We searched databases, scanned reference lists, and contacted trial investigators. Two reviewers collected and graded randomized controlled trials comparing oral vitamin D3 with placebo or no intervention in terms of bone mineral content/density (BMC/BMD), serum markers, and adverse events in pediatric NS.

Results:

We included 4 trials (164 subjects) with a collectively high risk of performance and/or detection bias. Although the vitamin D group had significantly more positive absolute change-from-baseline BMC than controls (mean difference 1.15; 95% CI 0.07-2-22;I 62%), the two trials were heterogeneous and included data. Moreover, in terms of other outcome measures, we did not find sufficient evidence of benefit from treatment. One study reported significantly improved parathyroid hormone levels but also a higher risk of hypercalciuria with vitamin D use. No nephrocalcinosis was reported. Subgroup analysis of first-episode NS revealed significantly more improved BMD with supplementation.

Conclusion:

Available evidence was low-quality and insufficient to recommend vitamin D supplementation in pediatric NS, although there may be benefit in first-episode NS. In contrast, vitamin D administration may be associated with hypercalciuria.
Payment for water-ecosystem services monitoring in Brazil
Authors: Lima Ana Paula Morais de , Prado Rachel Bardy , Latawiec Agnieszka Ewa
Published: August 2021

The reduction of tropical forests has generated a loss of ecosystem services across the globe. In Brazil, essential biomes related to water provision (such as the Atlantic Forest and Savanna) have been degraded, compromising water-ecosystem services. Payment for water-ecosystem services (water PES) has been implemented as a tool to stimulate changes in the use and management of these areas. Many water PES projects have emerged in Brazil using forest restoration, aiming to improve water ecosystem services. In this context, this study identified the types of monitoring carried out in Brazilian water PES projects, to include their main characteristics and gaps. Five Brazilian projects were selected for analysis as case studies. Interviews were then conducted with stakeholders to get current data on their monitoring practices. The data from the literature review, case study approach, and interviews were analyzed from the perspective of monitoring guides recommendations. Different aspects were analyzed, such as objectives, institutional arrangements, type of monitoring, indicators, and frequency of monitoring.  The study indicates that there is a lack of standardized methods, making it difficult to specify the results of the implemented actions. The central gap is related to benefit monitoring.  It is necessary to establish a holistic monitoring system, dealing with the ecosystem as a complex socio-ecological system. Some perspectives to solve the problems were proposed. The results of this work may help not only improve the current and future PES schemes in Brazil but also in other countries, especially developing ones, where vulnerable populations depend upon them.
A Novel Approach to Image Enhancement Based on Fuzzy Logic
Authors: Selmani Anissa , Seddik Hassene , Mzoughi Moussa
Published: August 2021

Image filtering, which removes or reduces noises from the contaminated images, is an important task in image processing. This paper presents a novel approach to the problem of noise reduction for gray-scale images. The proposed technique is able to remove the noise component, while adapting itself to the local noise intensity. In this way, the proposed algorithm can be considered as a modification of the median filter driven by fuzzy membership functions. Experimental results are compared to static median filter by numerical measures and visual inspection. As was expected, the new filter shows better performances.

Published: August 2021

Under the green building policy, the recycling of construction waste has become an important issue. However, many obstructions in the industrial chain of construction waste recycling, slow integration of production elements in the chain, and inefficient resource allocation hinder the development of the construction waste recycling industry. In this study, a co-evolution model of the industrial chain of construction waste recycling is constructed based on the Lotka–Volterra model, and the Jacobian matrix is used for stability analysis. Finally, a numerical simulation is performed. The simulation results indicate that: (1) There is a high product correlation between upstream and downstream enterprises in the industrial chain of construction waste recycling; (2) The conversion coefficient of supply and demand of upstream and downstream enterprises has a higher impact on and is more sensitive to the evolution of this industrial chain; (3) The co-evolution of upstream and downstream enterprises promotes the added value of products and maximizes the overall benefits of the industrial chain, which provides reference value and theoretical basis for the development of the industrial chain of construction waste recycling.

The resurgence of the Selk'nam. Dynamics of ethnoheterogenesis, ethnicity, and legal recognition in the Tierra del Fuego
Authors: Lastra-Bravo Javier
Published: August 2021

This article has two central objectives, on the one hand, to analyze the process by which the Selk'nam population was declared extinct on the island of Tierra del Fuego, putting special emphasis on the process of colonization and the consequences this brought, especially the process of assimilation and ethnocide. Subsequently, a theoretical review is made of the concepts of ethnicity and ethnogenesis as processes through which the resurgence of groups of individuals who currently recognize themselves as members of the indigenous Selk'nam group can be explained. In this sense, the concept of Ethnoheterogenesis is linked as a model through which the current processes of self-recognition of individuals with ethnic groups can be explained. To conclude the article focuses the discussion on recognizing those cultural aspects present today, the action of ethnic groups, and the need for legal and symbolic recognition of the current existence of Selk'nam ethnic groups.

Published: August 2021

Observa-se, nos últimos anos, um frequente emprego das Forças Armadas em ações subsidiárias tipo Garantia da Lei e da Ordem (GLO), especialmente em ambientes de favela. As especificidades desse tipo de ocupação, como vias estreitas e irregulares e o possível posicionamento multidirecional do atirador, são fatores que ocasionam grande dificuldade no atendimento e na evacuação de um possível ferido em combate. Além do exposto, a falta de capacitação técnica em procedimentos específicos de APH tático de tropas operacionais é outro ponto dificultador de sucesso no atendimento a um ferido. Este trabalho objetiva identificar possíveis pontos passíveis de melhoria no universo do Exército Brasileiro (EB), tanto no que tange à divulgação dos protocolos vigentes à força terrestre, quanto ao adestramento adequado e periódico da tropa. Para tal foi realizada ampla revisão de literatura pelos meios eletrônicos disponíveis dos protocolos internacionais, manuais de campanha do EB e artigos científicos, além de aplicação de questionário próprio do tipo direto a 52 militares oficiais e praças empregados em alguma GLO no RJ.

Authors: ÇELİK Halime , PARLAK Nezaket
Published: August 2021

A numerical study and parameter optimization was carried out to find the effects of geometric parameters and nanofluid concentration on heat transfer and pressure drop characteristics of a finned microchannel. Six dual rectangular fins with different layouts were placed in a single microchannel having rectangular cross section. The hydraulic diameter of the microchannel was kept constant and the length, width and angle of fin between the horizontal axes were determined as parameters. The water was selected as base fluid and the effect of volumetric concentration of nanofluids (Al2O3 (0% to 0.4%)) on fluid flow and heat transfer were investigated. Volumetric concentration of nanofluids and fin geometry was optimized with Response Surface Optimization method for the levels of different parameters and Computational Fluid Dynamics (CFD) analyses (ANSYS Fluent 18) was performed at different flow rates. CFD results calculated for the optimum finned microchannel were compared to those of the straight (finless) microchannel. As a result of the study, nanofluid concentration increment and fins improved the heat transfer and increased the pressure drop.
A COMPARATIVE STUDY OF DIFFUSION, THERMAL WAVE AND DUAL-PHASE-LAG HEAT CONDUCTION IN THIN LAYER
Authors: YUVARAJ R. , SENTHILKUMAR D.
Published: August 2021

In the present work, three different modes of heat conduction, diffusion, thermal wave, and dual-phase lag, across a thin layer subjected to a constant temperature and insulated boundary conditions are compared by using a finite element solution. The finite element model is developed by considering relaxation time to heat flux and relaxation time to temperature gradient for a single element. After assembling all the elements, the number of algebraic equations obtained is solved to predict the temperature distribution across the thin layer using Python. The solution predicted by the dual-phase lag is compared with that obtained by the single-phase Cattaneo–Vernotte’s model and diffusion Fourier model. The developed model is validated with analytical, numerical, and experimental solutions with good agreement. The temperature contours are plotted for all three conditions and the way it propagates differently through the thin layer is clearly shown. Further, the temperature variation at the center of the layer, at which collision occurred, is predicted and the speed of the thermal wave, infinite in the Fourier diffusion model and finite in both single and dual-phase lag, is examined under transient to steady-state condition.

The article considers ways to solve the problem of ensuring the energy safety of separation workshops of biological industries using the example of the Armavir Biofabrika PKP. The existing power limit does not allow increasing output. At the same time, a sufficient level of electricity supply at the existing facilities of the biofabric will allow to double the output of finished products practically. You can solve this problem using additional or redundant power sources, as well as high-efficiency electrical equipment. One solution to the problem may be to use the developed synchronized axial two-way contactless wind-solar generator and separator for polydisperse liquid systems. The designed generator will transform wind and solar energy into AC electricity, while it can be synchronized with an external three-phase AC system. Separator uses inevitable heat loss of asynchronous motor to preheat separated product.

A cidade de Recife-PE possui singularidades geográficas que interferem na distribuição temporal e espacial da precipitação, que está associada com fatores topográficos, deslocamento dos ventos, vegetação, urbanização, entre outros. Dessa forma, essa localidade apresenta um forte potencial para ocorrência de eventos extremos de precipitação, seja ele por alagamentos, inundações ou deslizamentos de terra afetando a qualidade de vida da população. Buscou-se analisar o comportamento dessa variável por meio dos dados mensais de precipitação compreendendo o período de 1961 a 2019, obtidos a partir do Banco de Dados Meteorológicos para Ensino e Pesquisa (BDMEP) do Instituto Nacional de Meteorologia (INMET), imagens do satélite GOES-12, do banco de dados do Centro de Previsão de Tempo e Estudos Climáticos (CPTEC/INPE) e dados do satélite Tropical Rainfall Measuring Mission (TRMM). Para verificar a ocorrência ou não de tendências nas séries temporais, utilizou-se o teste de Mann-Kendall (MK). Esse teste utiliza a hipótese nula H0, quando não há tendência de precipitação e a hipótese alternativa H1, quando há tendência na série de dados, para o mês de março negativamente ao nível de 5% (p<0,05), rejeitando-se a hipótese nula. A partir das imagens do satélite TRMM, dos dados do INMET e das imagens de satélite GOES-12, evidenciou-se que o sistema meteorológico Zona de Convergência Intertropical (ZCIT), com sua atividade convectiva favorável e sua posição climatológica mais ao sul do Equador contribuiu nos acumulados de precipitação observados em Recife-PE.
DESDE A DIALÉTICA DISCURSIVA EXPOSITIVO EXPLICATIVA VERSUS GÊNERO INFORMATIVO ATÉ A IDEOLOGIA DE GÊNEROS
Authors: Silva Moises Lopes
Published: August 2021

A confusão textual resultante de uma imposição ideológica na tipologia de texto introduziu mesclas de objetivos paradoxais como dialogicamente aceitáveis, por exemplo, o texto literário é dialético e não paradoxal ao texto não literário ainda que as características do primeiro inexistam no segundo; não se trata aqui de mesclas de tipologias normais numa discussão. A características do texto literário é a universalidade do tema, a verossimilhança, a catarse e a métrica (Souza, 2007) que são as mesmas do mundo do narrar (Bronckart, 2003), da narrativa (Adam, 1987) e da tipologia expositiva informativa reconfigurada para a tipologia descritiva de Adam (1987) em Pressus (2017). O artigo de opinião que surgiu como gênero textual em 2006 através do manual Artigo de Opinião escrito por Jaqueline P. Barbosa (Sequência didádica artigo de opinião, 2006) como proposição das escolas públicas do Estado de São Paulo trouxe como princípio o paradoxo e não a dialética quando Barbosa postulou que argumentar não é dar opinião abandonando em seguida o termo Artigo de Opinião em seus trabalhos futuros (Barbosa, 2010). Os alunos das escolas públicas passaram a confundir opinião com argumento e a paralaxe (Carvalho, 2015) própria de estudos ideológicos passou a postular paradoxo como dialética e assim fez-se a confusão desde o discurso expositivo explicativo (argumento com provas fatos evidências, não literário) versus  o informativo (propaganda, publicitário, narrativa, opinião, literário) até pretender postular ideologia de gênero.

Authors: S B Dr. Rashmi , B Mr. Raghavendra , V Mr. Sanketh
Published: August 2021

A CMOS low noise amplifier (LNA) for ultra-wideband (UWB) wireless applications is presented in this paper. The proposed CMOS low noise amplifier (LNA) is designed using common-gate (CG) topology as the first stage to achieve ultra-wideband input matching. The common-gate (CG) is cascaded with common- source (CS) topology with current-reused configuration to enhance the gain and noise figure (NF) performance of the LNA with low power. The Buffer stage is used as output matching network to improve the reflection coefficient. The proposed low noise amplifier (LNA) is implemented using CADENCE Virtuoso Analog and Digital Design Environment tool in 90nm CMOS technology. The LNA provides a forward voltage gain or power gain (S21) of 32.34dB , a minimum noise figure of 2dB, a reverse-isolation (S12) of less than - 38.74dB and an output reflection coefficient (S22) of less than -7.4dB for the entire ultra-wideband frequency range. The proposed LNA has an input reflection coefficient (S11) of less than -10dB for the ultra-wideband frequency range. It achieves input referred 1-dB compression point of 78.53dBm and input referred 3-dB compression point of 13dBm. It consumes only 24.226mW of power from a Vdd supply of 0.7V.
Malignant Transformation of Chronic Nonspecific Sialadenitis: A Rare Clinical Presentation
Authors: Ashish Gaurav , Ashish Gaurav
Published: August 2021

A 26-year-old man presented with a large, painless, mobile, pedunculated, fluctuant, and nontransilluminant swelling hanging in front of the left ear. He had undergone superficial parotidectomy 9 months ago elsewhere for chronic nonspecific sialadenitis of left parotid gland. The fine needle aspiration was nondiagnostic and revealed turbid dark yellow color fluid. A total parotidectomy was performed to remove the lesion completely as the tumor was involving the deep lobe. Histopathology was consistent with features of low-grade mucoepidermoid carcinoma. Immediate postoperatively the patient had a House and Brackman grade III left facial nerve paresis, which later improved to grade II. This unusual presentation of malignant transformation of chronic nonspecific sialadenitis is one of the rare unique reported cases to our knowledge.

Background

Coronavirus disease-19 (COVID-19) is a recent pandemic that is advancing at a rapid rate. The future course of the disease includes severe respiratory infection and also leads to death if unattended. Meticulous measures are necessary before attending any patient. The dental operatories and the clinic surroundings must be well sanitized so as to prevent the spread of pandemic.

Aim and objective

This review discusses in brief about the pathophysiology and course of COVID-19. Further, we discussed in detail the management aspects of patients in periodontal perspective and the sanitization procedures required for the dental clinic.

Review results

The SARS coronavirus enters the human circulation via the angiotensin-converting enzyme (ACE) receptors which are also found on the oral mucosal surfaces. Furin and Cathepsin L are the pro-inflammatory molecules released during pathogenesis of periodontitis and mediate the molecular pathways that help the virus invade into the host. The clinic set-up should be modified to best suit the pandemic conditions. This includes the three phases, i.e., phase I: preparatory phase; phase II: implementation phase; and phase III: follow-up. The patient management is explained based on the emergency needs of the patient based on the recent AAP classification of periodontal diseases and conditions 2017 as emergency, urgent, and elective treatment needs which have been explained in detail.

Conclusion

It can be strongly concluded that there is direct relationship between oral health and systemic health. The treatment procedures and sanitization protocols must be definitely modified. Further consensus and systematic reviews help us arriving at a more standardized protocol.

Clinical significance

This review would help clinicians modify the way they treat patients in the clinic and provide better services depending upon the emergency needs of the patient.
