O 'NÚMERO EXTRAORDINÁRIO' DA REVISTA BRASIL-PORTUGAL E O 4.º CENTENÁRIO DO DESCOBRIMENTO DO BRASIL
Authors: Silva Júlio
Published: April 2022

A Revista Brasil-Portugal (1889-1914) foi um periódico luso-brasileiro pertencente à Belle Époque das revistas ilustradas na viragem do século XIX europeu, dirigido às elites políticas e sociais do Brasil e de Portugal. Desenvolveu um projeto muito específico de construção de uma comunidade cultural luso-brasileira, através da divulgação nas suas páginas de inúmeros textos literários e gravuras de poetas, escritores e artistas portugueses e brasileiros. No entanto, também foi responsável pela edição de outras publicações como álbuns, almanaques e um número extraordinário em 1900. Este ano, em comemoração dos 400 anos da descoberta do Brasil por Pedro Álvares Cabral, o Brasil desenvolveu inúmeras iniciativas para comemorar este momento fundador da história nacional. Neste estudo, analisamos a natureza desta publicação e as características e conteúdos de sua edição que permitiram considerá-la pelo público e pela imprensa da época, tanto um livro, um álbum e um número especial da Revista Brasil- Portugal.
A FORTALEZA DE SANTA CATARINA DE RIBAMAR (PORTIMÃO) NO SÉCULO XVIII: O QUE NOS CONTA A HISTÓRIA E A ARQUEOLOGIA DA ARQUITETURA?
Authors: Galamba Bruna
Published: April 2022

A Fortaleza de Santa Catarina de Ribamar, em Portimão, foi construída no início do século XVII, de forma a prover segurança à população local. As ameaças de piratas e corsários eram uma constante. Apesar de a sua construção ser sólida, seguindo as normas da arquitetura abaluartada, quando chega ao século XVIII, é confrontada com três abalos de terra significativos. Em 1719, em 1722 e, em 1755, o mais conhecido de todos os terramotos, a fortaleza é fustigada pelas forças da natureza, tendo ainda, ficado submersa com o maremoto de 1755. Os sismos provocaram a ruína parcial da estrutura. Só em 1758 e em 1794 se dava por reparada a fortaleza, possibilitando a vivência do Capitão e soldados e a defesa ativa da margem direita do rio. Em 2020, em virtude de um levantamento fotogramétrico à estrutura, e a necessidade de estudar o sistema defensivo para requalificação futura, um estudo pela perspetiva da Arqueologia da Arquitetura entendeu-se como necessário. O século XVIII, deixou marcas na estrutura, permitiu a evolução do espaço e a fixação de novas entidades. Este artigo pretende dar a conhecer estas mudanças.
Mobile app use by medical students and residents in the clinical setting: an exploratory study
Authors: Fournier Karine
Published: April 2022

Introduction: Mobile devices and mobile applications facilitate access to clinical evidence at the point-of-care. Medical libraries play an important role in medical trainees' education, by subscribing to quality resources and by providing help and guidance on what apps to use. This study’s goal was to explore medical trainees' mobile applications use in the clinical setting to help inform collection development’s decisions and to provide insight on educational outreach. Perceived barriers and benefits of medical app use by clinical trainees was also explored.
Methods: A brief online survey (English and French) was sent to all University of Ottawa clerkship medical students and residents. The questionnaire consisted of multiple choices, Likert-scale, and open-ended questions.
Results: 208 English and 9 French responses were received. UpToDate was the most frequently used app, followed by MedCalc, Spectrum (CHEO) and Medscape. Respondents used medical apps mostly before and after meeting with patients and rarely while interacting with patients. Main benefits identified of medical app use were helping with decision-making, quick access to trustworthy clinical information, help with diagnosis and treatment options (e.g. medication dosage, drug interaction). Main barriers identified were costs, appearing unprofessional, lack of Canadian content and spotty hospital WiFi.
Conclusion: Libraries' involvement in providing access to trustworthy clinical resources to medical trainees is important to help shape trainees' development as medical professionals. Outreach to learners in the clinical setting is crucial to educate on what apps are available to them through the library collection.

Hypertension is one of the most common causes of cardiovascular diseases (CVDs) and is among the leading causes of death globally. Recent reports revealed that hypertension and related cardiovascular complications are gaining more importance in sub-Saharan Africa, especially in Nigeria. Plant herbs such as moringa (Moringa oleifera) leaves and ginger (Zingiber officinale) rhizomes are popular folklore for the management of hypertension, but limited scientific information is available on their possible synergistic effect in militating against the scourge of high blood pressure. This study sought to evaluate the effect of combination of moringa (Moringa oleifera) leaves and ginger (Zingiber officinale) root in different proportions. The proximate composition and mineral analysis of these combinations was assessed. Sample A contained 100% powdered moringa leaves, sample B contained 100% powdered ginger rhizomes, sample C contained 50% powdered moringa leaves and 50% powdered ginger rhizomes, sample D contained 25% powdered moringa leaves and 75% powdered ginger rhizomes, while sample E contained 75% powdered moringa leaves and 25% powdered ginger rhizomes. The proximate composition of moringa leaves and ginger rhizome showed that moringa had a higher percentage of moisture, fat and carbohydrate than ginger while ginger had a higher percentage of protein, fibre and ash. Upon combination at different proportions, a number of positive synergy was observed. The different combinations of the two herbal plants show increased percentage of the proximate compositions and minerals compared to the lower individual percentage in nearly all parameters assessed. This can be harnessed to achieve the desired nutrient and nutraceuticals aimed at managing hypertension.

Hypertension is when systolic blood pressure is greater than 140 mmHg, and diastolic blood pressure is greater than 90 mmHg caused by complex factors and related conditions. Hypertension in the elderly often occurs because cell structure and function change with increasing age, affecting health and disease. Sports such as hypertension exercise can encourage the heart to work optimally. The blood vessels will stretch, and blood flow will decrease temporarily for about 30-120 minutes. It will return to blood pressure before doing the exercise. This study aims to determine the effect of hypertension exercise on blood pressure in the elderly in Legonkulon village, Subang regency, West Java, Indonesia, in 2022. This quantitative research method has a Pre-experiment design one group.

Astrology is an advanced and glamorous science, which plays a major role in predicting different events that happen in human life. It consists of scientific and analytical computations that depend on various phases of the orbital movements in the form of degrees; the précised level of planet movements can predict the cosmic energy and also articulate the accurate interpretations of horoscope information on the basis of a constellation of a given birth chart. Way back in 200 BC, an astronomer has adopted Mathematical interventions to measure the distance of planets from the sun and predicted various astrological manifestations. Nowadays, at the global platform, a very few numbers of research articles described the Mathematical and Pragmatic approach of astrological predictions. In this paradigm, we have formulated an advanced Stochastic Probability Convergence predictive model to describe the practical interventions and different features of horoscope and advancement of cosmic energy on the basis of comprehensive phenomena. This formulated model will be highly useful for astrologers to forecast the cosmic energy and different malafacies of human life on a day-to-day basis. Our formulated predictive model is handy and also capable to produce the accurate predictions of horoscopes. Based on the model convergence outputs, the Astronomers drew the real astrological interpretations scientifically without any Jargon and personal assumptions.

Published: April 2022

Na ciência discute-se a cultura organizacional e a performance da companhia e defende-se que os valores sejam vistos como essência para criação de padrões comportamentais que podem gerar vantagens competitivas. Essas vantagens podem incluir decisões gerenciais concernentes aos custos. Esse estudo analisa os valores dominantes para as 14 empresas brasileiras de capital aberto do setor de FMCG  (Fast Moving Consumer Goods) listadas na B3 e classificadas como Setor Econômico de Consumo Anticíclico. Os valores foram categorizados a partir das dimensões culturais propostas por Schwartz e Ros (1995). A determinação dos valores relevantes foi baseada em levantamento de material institucional das empresas e os custos pegajosos foram tomados dos Demonstrativos de Resultado. A hipótese investigada foi que os valores, através da influência sobre o comportamento dos gestores, seriam capazes de afetar as decisões de ajustes da estrutura de custo, levando a assimetrias de custos diferentes entre as empresas de acordo com os valores dominantes de cada uma. Para o presente estudo, usou-se a análise de conteúdo para categorização das empresas de acordo com os tipos de cultura, e também o teste de médias para identificar se os valores dominantes dicotômicos apresentavam comportamento de custo diferentes. Os resultados não foram estatisticamente significativos e, portanto, não foi possível evidenciar que os valores organizacionais dominantes são capazes de gerar comportamentos diferentes dos custos em relação à variação da receita.
Could increasing dividends predict asset valuations in the Brazilian electricity sector?
Authors: Da Silva Alexandre Rodrigues , Kirch Guilherme
Published: April 2022

According to Wang (2004), the stock markets have different behaviors in the short and long term. Dividend investment sees fewer years with losses, adding significant utility to the investor (CLEMENS, 2012). The purpose of this study is to demonstrate whether the payment of dividends can relate to the future gain in value of their respective shares in companies in the Brazilian electricity sector. Results: the findings showed a positive variation in the value of assets one year after their acquisition in that group that had a positive change in dividends in the previous year, compatible with the “Dogs of Dow” strategy, and this relationship was not found for longer periods of time, both for dividends and for stocks prices. Thus, it is suggested that the strategy of seeking asset valuation based on its previous dividend payment should be limited to the previous year's dividend payment period, aiming at a horizon of one year after the purchase of the respective company's share.

Published: April 2022

This study examined the impact of cash flow, capital account liberalization (CAL) on investment growth of firms from both the direct and indirect channels, using the disaggregated firm-level data of 44 tradable and 31 non-tradable firms for the period of 2006 to 2016. It employed the differenced dynamic panel regression technique. Among others the results revealed that CAL is positively but insignificantly related to investment growth, and investment growth appeared to be determined by cash flow (internal) thereby indicating the presence of financial constraint for both samples. However, when we compared the level of financial constraint of the tradable and non-tradable firms, judging by the magnitude of the coefficients of cash flows in both samples, non-tradable firms were found to be severely financially constrained. The study also determined that CAL appeared to be sensitive to investment growth for both firm types through the indirect route, precisely the capital/credit availability channel measured as cash flow. The level of capital openness is still low for tradable firms hence the need for more but monitored openness.
Study of Ashab Al-Kahf's Story in the Book of Fadhâ’il al-Khamsah min al-Shihahi al-Sittah: A Naturalistic Hermeneutical Perspective
Authors:   Universitas Gadjah Mada (UGM), Indonesia, Manshur Fadlil Munawwar
Published: April 2022

This study discusses the story of Ashab al-Kahf in the book of Fadhâ’il al-Khamsah min al-Shihahi al-Sittah by As-Sayyid Murtadha Al-Huseiny Fairuzabadi in which there are interesting and intelligent dialogues between Ali bin Abi Talib and a Jewish priest. Ali bin Abi Talib was one of the Prophet Muhammad’s companions who was smart and very trusted. The story of Ashabul-Kahf contains many lessons and life’s wisdom for humans who consistently maintain their faith and stay away from the power oppressive center to their people. The formal object of this research is the story of Ashabul-Kahf which is very popular in Islamic society, both in the Arab world and outside the Arab world. The material object uses Fadhâ’il al-Khamsah min al-Shihahi al-Sittah Book. This study uses the naturalistic hermeneutic theory by Mantzavinos. The results showed that the actions of seven young men who fled to the cave due to they were being chased by the tyrannical King Dikyanus and they did not feel like sleeping in the cave for 309 years. This research reveals a series of material events since they fled from the kingdom and were chased by King Dikyanu’s army and finally they fell asleep in the cave for more than three centuries until they woke up from their long sleep and were again killed by God. Between one event material with others each other has a relationship of interrelated meaning. In this study, it is proven that the use of naturalistic hermeneutic theory can guide researchers in revealing the hidden actions meaning of the seven young men from the pursuit of King Dikyanus in the cave. The meaning revealed is that there is a causal relationship between the story of Ashabul-Kahf text and its readers (researchers). The story complexity in the story’s text is later explained through the nexus concept, which essentially looks for material that occurs in the historical reality area and expresses it through an exclusive causal relationship. Therefore, through this nexus, the problematic meaning of Ashabul-Kahf story can be revealed.
Modal Space Controller for Hydraulically Driven Six Degree of Freedom Parallel Manipulator
Authors: P. O. Ogbobe  , C. N. Okoye
Published: April 2022

This paper presents the Modal space decoupled control for a hydraulically driven parallel mechanism has been presented. The approach is based on singular values decomposition to the properties of joint-space inverse mass matrix, and mapping of the control and feedback variables from the joint space to the decoupling modal space. The method transformed highly coupled six-input six-output dynamics into six independent single-input single-output (SISO) 1 DOF hydraulically driven mechanical systems. The novelty in this method is that the signals including control errors, control outputs and pressure feedbacks are transformed into decoupled modal space and also the proportional gains and dynamic pressure feedback are tuned in modal space. The results indicate that the conventional controller can only attenuate the resonance peaks of the lower eigenfrequencies of six rigid modes properly, and the peaking points of other relative higher eigenfrequencies are over damped, The further results show that it is very effective to design and tune the system in modal space and that the bandwidth increased substantially except surge (x) and sway (y) motions, each degree of freedom can be almost tuned independently and their bandwidths can be increased near to the undamped eigenfrequencies.

Published: April 2022

Bangladesh is crisscrossed by rivers and inland waterways have been playing a significant role to the transportation of goods. For nation’s economic prospects it is very important to develop the inland waterways transportation systems in Bangladesh. But inland waterways in Bangladesh are facing challenges due to many problems in spite of having good prospects. Therefore, the objective of the study is to examine the present IWT systems, its challenges and how it can contribute more than others transportation systems to our national economy. this paper is mainly based on secondary data. The data is collected from journal papers, internet, newspaper, books, and articles. Data is also gathered from different maritime authority’s website. The research findings indicate that the Bangladeshi inland waterways have huge prospects, but lack of knowledge gap of current condition of inland navigability, not conducting hydrographic survey after 1989, lack of poor management, inadequate inland port facilities, low quality vessel and poor inland connectivity are the reasons for all of this problem. Inland waterways transports are environmentally friendly than others transportation systems and many local business person, exporter, importer will be benefited by using IWT. But authority should have to utilize the inland water ways in a right manner. Adequate the depth and air draft should have to be maintained and the inland port facilities improvement and infrastructure development are necessary for IWT.

Background: Ovarian cancer has the highest mortality of all gynecologic malignancies, howeverthere is no proven effective screening for ovarian cancer. Evidence suggests that epithelial ovarian cancer begins in the fallopian tubes. Prophylactic bilateral total salpingectomy has been shown to reduce the risk of epithelial ovarian cancer and is now recommended to be considered at the time of sterilization procedures. There are limited well designed clinical trials that compare the safety and feasibility of total salpingectomy to that of traditional partial salpingectomy for tubal sterilization in obstetrics. We thus conducted a randomized controlled trial to assess the safety of bilateral total salpingectomy at the time of cesarean delivery. Methods: We conducted a non-inferiority randomized controlled trial at the Mayo Clinic, Rochester, Minnesota. Women age 21 years and older who were undergoing cesarean delivery and desired concomitant sterilization were enrolled between May 17, 2017 and July 16, 2018. Stratified randomization was performed based on number of previous cesarean deliveries and their Basal Metabolic Index, into a bilateral total salpingectomy (BTS) group and bilateral partial salpingectomy (BPS) group. All salpingectomies were performed using clamps and suture. The primary outcome was to compare the mean peri-operative hemoglobin change for both groups. Secondary objectives included sterilization completion time, postoperative length of stay, estimated blood loss, postoperative pain and adverse events. Results: Of the 111 women screened, 40 were enrolled and randomized. Of these, 38 underwent the assigned procedure (18 BTS, 20 BPS). No difference in Mean ± SD hemoglobin drop between groups (1.4 ± 0.7 g/dL for the BPS group and 1.8 ± 1.0 g/dL for the BTS group, p = 0.08), however the point estimate of –0.4 is very close to the non-inferiority margin of –0.5, and the CI widely exceeds the non-inferiority margin (95% CI –0.99, 0.17). Therefore non-inferiority was not shown. Mean time to completion of sterilization procedure was significantly longer in the BTS group (16.3 ± 5.6 minutes for the BTS group vs 5.1 ± 1.6 minutes for the BPS group, p < 0.01). No significant differences for other outcome measures. Conclusions: Bilateral total salpingectomy is not non-inferior to tradiational bilateral partial salpingectomy with regards to postoperative hemoglobin drop, and is associated with a small increase in operative time. There, however, was no difference in adverse events, postoperative length of stay and postoperative pain between the two groups. This information may be helpful when counseling patients.
A patient and physician friendly stimulation protocol using long acting FSH and progestin priming should be the future of IVF
Authors: Kadour-Peero Einav , Dahan Michael H.
Published: April 2022

Objective: Needle phobias and concern about the discomfort remain significant disincentives for many women contemplating in vitro fertilization (IVF). The number of injections required in an IVF cycle is increased by the use of most medications which prevent premature ovulation. Mechanism: long-acting follicular stimulation hormone (LA-FSH) that was developed 15 years ago has the ability to stimulate folliculogenesis in a patient for seven days with a single injection, with comparable outcomes to daily injections in assisted reproduction. Many clinicians were hesitated to use it in their patients, fearing an inability to decrease levels of FSH stimulation for 7 days and the resultant increased risks of ovarian hyperstimulation syndrome (OHSS). This occurred prior to the widespread adoption of Gonadotropin-releasing hormone (GnRH)-agonist triggering and freeze all embryos for the prevention of OHSS. Conclusions: We suggest LA-FSH protocol with the use of progestins to prevent ovulation, which could be an alternative way to treat IVF patients without any compromise of the effectiveness of the treatments or the safety of the patients.

Формулювання проблеми. Рівняння Юнга зв'язує кут змочування  і коефіцієнти поверхневого натягу  на межі середовищ. З цього рівняння випливає, що макроскопічний параметр  не залежать від властивостей молекул, а уявлення про силове поле між молекулами враховується тільки на лінії їх розмежування. Тому студенти роблять помилковий висновок, що сили міжмолекулярної взаємодії діють тільки на лінії розмежування середовищ. Отже, виконання лабораторної роботи за вищенаведеною тематикою вирішує цю проблему.

Результати. Залежність сили відриву від периметра диска (лінії розмежування рідини і твердого тіла) виявилася нелінійною і прямо пропорційною змоченої площі. Коефіцієнт пропорційності склав величину  ≈ 40 Н /  м2.
Висновки. 1) Сила відриву диска від поверхні води непропорційна периметру диску. Це доводить той факт, що поверхневий натяг рідини як особлива реально діюча сила себе у цьому досліді не проявляє. 2) Незмінність величини сили відриву одного і того ж диска при збільшенні кількості виконаних в ньому отворів і залежність сили відриву тільки від площі поверхні цільного диска доводить той факт, що в утриманні диска беруть участь всі молекули, що знаходяться в контактному шарі диска і рідини.
FORMATION OF MODERN MATHEMATICAL APPROACH TO SOLVING PROBLEMS OF PHYSICS

Published: April 2022

Formulation of the problem. Precision studies of the Higgs boson, supersymmetric particles, the magnetic moment of the muon, electric dipole moment of the electron, flavor anomalies demonstrate the deviation beyond Standard Model. They are connected with a new understanding of quantum field theory through the unification of gravity with particle physics in the framework of string theory - the powerful instrument, which has changed the theory picture. The article is devoted to the study of new physics through these two components. First, we considered particle physics in terms of the latest experimental data and then moved on to the mathematical apparatus of string theory.
Materials and methods. The N = 2 Yang-Mills theory is the heterotic string analog determined in ten-dimensional space: four usual space-time coordinates and six extra dimensions, known as Calabi-Yau manifold in weighted projective space. We studied the Calabi-Yau manifold in terms of both differential forms and reflexive polyhedrа to extract the elementary particle information. For further work with Calabi-Yau manifolds, differential forms for calculation of cohomology groups and reflexive polyhedrа for calculation of Hodge numbers were used. We used two definitions of general properties of toric varieties: hypersurfaces in terms of differential forms and projective space in terms of reflexive polyhedral.  Then we investigated lattice polyhedra ∆ which gives rise to families of Calabi-Yau hypersurfaces in weighted projective space, P∆. Such polyhedra admit a combinatorial characterization and are called reflexive polyhedra. 
Results. The comparison of two approaches to the description of Calabi-Yau manifold as a complex manifold and as weighted projective space led us to the conclusion about the equivalence of these two treatments in the context of calculation of the Euler characteristic. As Euler’s characteristic for elementary particle physics is the number of generations of quarks and leptons, the selection of Calabi-Yau manifolds with appropriate topological properties is one of the urgent problems of modern physics. It is necessary to stress that the important result of our paper is the coincidence of the value of the Euler characteristic, found in terms of Dolbeault cohomology and terms of reflexive polyhedral. The obtained information about topological invariants is necessary for predicting the number of generations in particle physics. 
Conclusions. Although a unified theory of all interactions has not yet been found, however, certain aspects related to the interpretation of the unified theory of all interactions in terms of modern mathematics give their significant results. Therefore, the use and development of the apparatus of algebraic geometry for finding topological invariants that have the value of observables in physics is an urgent task.

In recent years large number of emerging automated applications faces the need to have recognition abilities of persons using their own self biometrics, before they can access the applications services. Nowadays, Biometric recognition is used, it can be used as automatic identification or automatic verification of persons based on their physiological or behavioral characteristics. There are no perfect biometric measurements; each biometry has its advantages and limitations. Each biometry requires specific vital identity to answer the identification or verification question. The suitability of a particular biometry for a particular application depends on many factors. Hand geometry/shape is a very simple biometric technology that uses the measurements of human hand to verify the identity of the individuals. The measurements include the distance between certain mark points, shape and width of fingers and size of palm. The biometric systems that employing hand geometry become widely used since they have high public acceptance. This article aims to survey several articles found in literature about hand based biometric system, and to compare different methods of biometric recognition that based on hand geometry.

The growing Internet access and easy access to it have resulted in a significant increase in e-content, which, along with many benefits, has caused problems for users. Internet users simply cannot find the content they need from this massive amount of data. Users are faced with a lot of suggestions for choosing goods, buying items, selecting music and videos, and more. Advantage systems can be used to overcome these problems. Today, with the spread of people’s use of cyberspace, such as web sites and social networks, and increasing the need for conscious and clever selection of people, recommender systems has been extensively investigated. Although the neural network can identify the connections between the inputs and outputs of a dataset, but in order to achieve the proper performance of the neural network, a proper structure should be considered. We will use the mantle algorithm to determine this structure. The mantle algorithm is a form of traditional genetic algorithm that uses local search to reduce the time to achieve optimal response. Genetic algorithms are created to search across the search space, while the local search, the neighborhood of the neighborhood, finds every response found by the genetic algorithm to find better answers. This algorithm seeks to find the optimal values for the parameters of the neural network method, so optimal solutions of the memetic algorithm is considered to be used to set parameters for the neural network method. The results of this study show the desirable performance of the proposed approach in this study.
