Domestic tourism is the largest form of tourism in the world, both in terms of tourist flow and revenue. Nevertheless, relatively it is overlooked by governments and scholars of most developing countries. Consequently, this article has tried to contribute to domestic tourism scholarship by exploring domestic tourism in Ethiopia, intending to uncover the trends, prospects, promotional marketing, and challenges. The research was descriptive in its design and has utilized primary and secondary data collected through questionnaires, interviews, and reviewed archives. The primary data were gathered from 386 domestic tourists and 37 tourism experts at four different destinations. The data were analyzed using descriptive statistics, content, and text analysis using SPSS and Excel software programs. The result revealed that tourism in Ethiopia, in general, has been rising, but the absence of domestic tourism data at the national level weakens the generalization and was evidence to the level of attention given to the sector. Domestic tourism was found to be misconceived by most tourism experts and businesses. The result further indicated the culture of tourism in Ethiopia, domestic tourism development potentials, and its challenges. Conclusions and recommendations vital for policymakers and practitioners are also provided.

Superconducting fault current limiters (SFCLs) are the devices that uses the superconducting properties of the materials to limit the fault current. In comparison to the conventional fault current limiters (FCLs), the SFCL has advantage that its current limiting property is inherent and no external controls are required. However, to achieve the exact current limiting ratings with other characteristics like quench time, recovery time, peak current etc. a design optimization is required. Since the whole characteristics of SFCL depends upon the superconducting material adopted, and the parameters of cooling systems. The parameters defining the behavior of these two entities are selected as optimization variables. Because in this work second-generation high temperature superconducting (HTS) material known as YBCO (Yttrium Barium Copper Oxide ) is considered. Hence, in this paper non-dominated Sorting GA (NSGA-II) optimization algorithm is adopted that exploits the 2G YBCO mathematical model relating its electrical and thermal characteristics and cooling system specifications to find the optimal parameters according to the requirements (or objectives) of resistive-SFCL. The simulation results show that the presented algorithm is able to achieve multiple design objectives (required for SFCL) simultaneously within the range of 5%.

Crack detection has always been a dominant requirement for steel industries to ensure quality production and seamless infrastructure maintenance. However, application complexities and defect morphological differences make existing approaches confined. Steel-strip surface often undergoes scratch, crack and fatigue conditions during production. Manual crack detection schemes are no longer effective in current day complex environment. Amongst major steel strip crack detection approaches vision based techniques have found potential; Filamentous crack which is caused due to fatigue or strain is fine-grained and thin and hence highly difficult to be detected by classical morphology and static threshold based schemes. In the present work steel strip surface (filamentous) crack detection system has been developed which employs Varying-Morphological Segmentation (VMS) also called Neuron-Model Segmentation (NMS) in conjunction with local directive filtering and active contour propagation. The proposed method can be stated as an augmented variational framework that employs multi-directional filters for local crack-region identification followed by automated multi-directional region growing and iterative contour evolution which performs level set energy minimization to achieve accurate crack detection even under topological non-linearity and varying illumination conditions Simulation results with standard benchmark data has confirmed that the proposed method exhibits satisfactory performance for steel strip surface cracks.

Outward appearance was a characteristic and incredible method for human correspondence. Perceiving unconstrained facial activities in any case, is trying because of unpretentious facial miss happening, visit head developments and vague and unsure facial movement estimation. In light of these difficulties, ebb and flow look into in outward appearance acknowledgment is restricted to presented articulations and frequently in frontal view. An unconstrained outward appearance is described by inflexible head developments and non-rigid facial strong developments. All the more critically, it is the intelligible and steady spatiotemporal collaborations among unbending and non-rigid facial movements that produce an important outward appearance. Perceiving this reality, we present a bound together probabilistic facial activity model dependent on the Dynamic Bayesian system (DBN) to all the while and intelligibly speak to unbending and non-rigid facial movements, their spatiotemporal conditions, and their picture estimations. Propelled AI techniques are acquainted with gain proficiency with the model dependent on both preparing information and emotional earlier information. Given the model and the estimations of facial movements, facial activity acknowledgment is practiced through probabilistic surmising by deliberately incorporating visual estimations with the facial activity model. Analyses show that contrasted with the best in class strategies, the proposed framework yields huge enhancements in perceiving both inflexible and non-rigid facial movements, particularly for unconstrained outward appearances.

Laser triangulation 3D scanning machine is one of many types of 3D scanning technologies that are currently available in the current market. It is mainly use to capture object profiles as well as for measurement. Therefore, the measurement accuracy of laser triangulation 3D scanner was assessed and presented in paper. Three solid aluminum calibration block with known dimensions were fabricated by using CNC machine and these samples were named based on its profiles which are round, square and complex. Besides the laser triangulation 3D scanning machine, two more measuring equipment which are Vernier caliper and coordinate measuring machine were used as benchmarks. Three profiles were chose for each calibration block samples that made up of 9 profiles that have been measured and the deviation between the measuring values were analyzed. The results shown that the lowest deviation values for most of the profiles are from coordinate measuring machine and Vernier caliper measurement data. Nevertheless, the measurement deviation for laser triangulation 3D scanner are found to be comparable with other equipment.

In this paper an attempt has been made to select best crown material for molar tooth, So that an appropriate material can be placed in the human body which is most difficult task .so for designing a molar crown, modeling is done in pro/engineer software, it is one of the parametric 3D CAD/CAM/CAE solution widely used by mechanical engineers for designing any product .this software creates a complete 3D Digital model of the product. For this extensive research, design for all crowns will be the same but only material properties will be different. After design, failure analysis is done. Loss of ability to function normally is the study of failure analysis. This is accomplished by considering various loading conditions .Here finite element analysis is used, the standard principle underlying the FEM are simple. The word finite is used to describe the limited, or finite, number of degrees of freedom used to model the behavior of each element, the element are assumed to be connected to one another but only at interconnected joints, known as nodes. Considering a body through which the distribution of a field variable I.e. displacement or stress is required, this body could be subjected to various loads. Problem is solved by two methods: static fatigue and dynamic fatigue

Systematic Transfer Plan (STP) is a plan where an investor moves from one scheme to another a fixed amount of money, typically from debt funds to equity funds. STP is similar to SIPs or systematic investment plans, where money is moved from bank account to mutual equity funds. In STP, money is transferred in a few installments from a debt mutual fund to a mutual equity fund, so that the total purchase price is weighted suppose investor have earned 20 lakh from an asset sale and want to invest over 24 months in an equity fund through STP. Investor must first pick a debt fund that gives STP choice to invest in an equity fund. Then, choose an equity fund. Invest Rs 20 lakh in the debt fund and then determine the balance from the debt fund to the equity fund and the duration. In the alternative investment plan, the Systematic Transfer Plan (STP) has emerged for a large number of investors interested in high returns but less risk with lump sum investments. The purpose of the study is to know how to put money into STP reduces the risk of market timing and also helps investors to gain more from their source corpus by investing in debt funds. Results of the study found that awareness and operational framework, on the other hand, is one of the key barriers that investors face. The strategy of rupee cost average is an approach that motivates the investor to invest in a systematic transfer plan to gain from market timing risk. This research is also beneficial. The present study also allows investors to analyze the decisions and determine whether or not to invest in them and provides advice to protect their financial goals.

In the wireless sensor networks (WSNs), the upholding the energy and routing formation at every sensor node is the major issues. The distance from base station and internal node mainly has imbalanced in the energy consumption during transformation of the data. To reduce the energy upholding and the data aggregation routing issues in Centralized Clustering-Task Scheduling for wireless sensor networks (WSNs), this paper focuses on a Cluster-Based Data Aggregation Routing with Genetic search Algorithm (CDARGA) , which reduces the energy consumption in a hyper round model. The proposed data aggregation routing protocol using the Genetic Algorithm (GA) estimates the fitness function using the three key parameters distance, energy, and Hyper round policy. The proposed methods were compared with RP-MAC and the experimental result shows that the proposed protocol is superior to RP-MAC protocol and the proposed algorithm improves the network lifetime which can used in real time application.

Mário de Sá-Carneiro foi um poeta expoente do modernismo português cuja obra tem a identidade como um dos temas mais recorrentes. Nesse estudo iremos investigar como a noção de identidade é representada de forma desintegrada na obra do autor, a partir da análise de três poemas: “Ângulo”, “7” e “Escavação”. Os poemas foram analisados individual e comparativamente, levando em conta os planos temático, sonoro, estrutural, semântico e sintático. Entendemos que os três poemas dialogam intimamente entre si em todos esses planos analíticos quando tomamos por base a temática da desintegração da identidade e ruína de si mesmo. Entendemos, ainda, que a ideia de desintegração identitária está acompanhada de uma sensação de não-pertencimento, tanto em relação ao mundo quanto em relação a si mesmo: por vezes o eu-lírico não se vê nele mesmo e nem em um outro.

Authors: Esmaeili Ashkan , Fakharian Mohammadamin , Amiri Abyaneh Yasaman
Published: April 2020

The linear system with missing information is
investigated in this paper. New methods are

introduced to improve the Mean Squared Error (MSE)

on the test set in comparison to state-of-the-art method

s, through appropriate tuning of Bias-Variance

trade-off. The concept is to cluster the data and

adapt the learning model to each cluster. Hence,

we set forth a controlled bias into the problem and

positively utilize it to enhance learning capability on

the instances considered in some specific

neighborhood. To deal with missing infrormation,

we propose a novel algorithm "Missing-SCOP" based

on SCOP-KMEANS algorithm introduced by Wagstaff,

 et al., utilizing the missing pattern of the dataset for

construction of a soft-constraint matrix and clustering

in missing scenario. It is shown that controlled

over-fitting suggested by our algorithm improves

prediction accuracy in various cases.

Numerical experiments approve the efficacy of our

 proposed algorithm in enhancing the prediction

 accuracy.

Assumindo os aspectos da pesquisa qualitativa, este artigo explicita uma análise dos trabalhos que enfocaram a Investigação Matemática enquanto tema de estudo e que foram publicados nas edições XI e XII do Encontro Nacional de Educação Matemática - ENEM. Com o objetivo de identificar, nesses trabalhos, possíveis equívocos na compreensão do que são tarefas de Investigação Matemática e, elucidar algumas diferenças entre elas e os demais tipos de tarefas matemáticas, interrogamos: as “confusões” entre as tarefas de Investigação Matemática e outros tipos de tarefas utilizadas para o ensino de Matemática estão presentes nos trabalhos sobre Investigação Matemática nas edições do XI e XII ENEM? Há especificidades que permitam distinguir uma tarefa de Investigação Matemática das tarefas de Modelagem Matemática? E das tarefas de Resolução de Problemas? E dos Exercícios? Como síntese do percebido e articulado afirmamos que, nas edições do XI e XII ENEM, houve a presença de equívocos na concepção do que são tarefas de Investigação Matemática, por vezes, confundidas com os demais tipos de tarefas, na maior parte dos casos, com as tarefas de Modelagem Matemática. Entre as diferenças percebidas, afirmamos que as tarefas de Investigação Matemática possuem estrutura aberta e situam-se em contextos exclusivamente matemáticos. Os problemas, apresentam-se situados nos contextos reais e semirreais, com estrutura enunciativa fechada e sem direcionamento e questionamento pré-estabelecido. As tarefas de Modelagem Matemática são estruturalmente abertas, situadas em contexto quase que exclusivamente reais e geralmente são compostas por notícias, vídeos e outros recursos que trazem à tona um tema não matemático para ser investigado. Ressaltamos a necessidade do cuidado e atenção à teoria, ao assumir diferentes metodologias para organizar o ensino de matemática, de modo que os aspectos teórico-metodológicos anunciados sejam condizentes com a prática realizada.

A implantação da educação culturalmente relevante auxilia no desenvolvimento do aprendizado intelectual, social e político dos alunos por meio da utilização de referências culturais para desencadear o conhecimento matemático. Esse tipo de educação utiliza a experiências prévias de alunos para tornar o aprendizado relevante e efetivo, pois visa reforçar a sua conexão com as atividades escolares. As escolas culturalmente relevantes contextualizam a instrução e as práticas escolares enquanto mantém o rigor acadêmico. Nessas escolas, os líderes escolares, os professores e os funcionários são capazes de reconhecer e construir com base nos pontos fortes dos alunos por meio da aplicação de estratégias instrucionais que são culturalmente relevantes. A liderança culturalmente relevante está enraizada na convicção de que os alunos são capazes de se destacarem em projetos acadêmicos. Existe a necessidade de facilitar a implementação da pedagogia culturalmente relevante nos currículos escolares, que é projetada para embeber a cultura escolar nos backgrounds culturais dos alunos, auxiliando-os a conceituar o conhecimento. As abordagens da etnomatemática e da pedagogia culturalmente relevante no currículo matemático visam tornar os conteúdos matemáticos relevantes para os alunos. Assim, o objetivo desse artigo teórico é discutir os princípios da educação culturalmente relevante de acordo com a perspectiva etnomatemática.

Abstract
All-trans retinoic acid (ATRA) induces complete remission in a high proportion of acute promyelocytic leukemia (APL). Nevertheless it is be associated with adverse drug reactions that might be life-threatening including differentiation syndrome, myocarditis, myositis, Sweet’s syndrome and ulcers. We describe a case of APL who during induction therapy developed ATRA syndrome, cardiac arrhythmia and multiple episodes of intestinal necrosis that required surgery. In particular, we report here for the first intestinal necrosis attributable to ATRA treatment in the absence of histological evidence of promyelocytes infiltration or leukocytoclastic vasculitis.

Published: April 2020

The article presents the analysis of the interactions between the impeller and the vaned diffuser of a radial flow pump. The tests were carried out on the so-called SHF impeller, coupled with a vaned diffuser, and working with air. The particularity of this machine is that the diffuser design flow rate corresponds to 80% of the impeller one. All experimental works were performed at the Fluid Mechanics Laboratory in ENSAM, Lille, France. Investigations have been made for five different flow rates. Global performances of the machine are evaluated thanks to pressure measurements and averaged velocities obtain with a three hole probe, at nine angular positions at diffuser inlet and outlet just as five radial positions in a middle section of a blade-to-blade passage. A post-processing procedure, based on statistical tools, was applied to the experimental results in order to reach a better understanding of the phenomena. In another approach, a numerical simulation of the flow inside the pump, for eight different relative angular positions of the diffuser relative to the impeller (Frozen rotor) was performed by the STAR-CCM+ software.

The study aimed to examine the profitability and find out the production constraints of small-scale tomato farming. The study was undertaken in Bau-Bau Municipality in Southeast Sulawesi province. Respondents consisted of 26 farmers who were selected from the total population of 104 tomato farmers. Data were collected using questionnaires and in-depth interviews. Data analysis was performed using cost and returns analysis, R/C ratio, and descriptive statistics. The average net returns per growing season of three months were Rp46,606,477. Tomato production is a profitable venture with the R/C ratio being 5.69. The main production constraints were rainfall irregularity, pest and disease occurrence, price fluctuation, poor soil fertility, low productivity, and labor shortage. Tomato production provides high income to the farmers and supports employment generation, food and nutrition security, and local economic growth. There should be integrated efforts to address these constraints to maintain tomato production and competitiveness and to ensure the sustainability of tomato farming.

Published: April 2020

Homeovox, a multicomponent homeopathic treatment for laryngitis of various etiologies, was tested for allergenic properties and immunotoxicity.

Methods. 80 male albino guinea pigs and 180 male СВА, C57BL/6 and F1 hybrid (CBAхС57BL/6) mice were used in the study. In order to assess immunotoxicity, Homeovox was administrated orally to mice for 14 days at doses of 100 mg/kg and 1 000 mg/kg. To assess the allergenic properties of Homeovox, albino guinea pigs were also given the drug at doses of 100 mg/kg and 1 000 mg/kg according to the standard immunization schedules.

Results. Oral administration of Homeovox to mice for 14 days at doses of 100 mg/kg and 1 000 mg/kg did not cause significant changes in the main characteristics of immune response compared to controls. When assessing allergenicity, Homeovox at doses 100 mg/kg and 1 000 mg/kg administered according to the standard immunization schedules did not induce systemic anaphylaxis or active skin anaphylaxis in albino guinea pigs. The immunization of guinea pigs by Homeovox at the same doses in a mixture with Freund's complete adjuvant caused no delayed allergic reactions. Homeovox at a single oral dose of 1 000 mg/kg significantly decreased concanavalin A-induced inflammation in CBA mice by 58.4 %.

Conclusion. Within the dosage range investigated, Homeovox does not induce immunotoxicity, immediate- or delayed-type allergic or pseudoallergic reactions.
Émile Zola’s Climate History of the Second Empire
Authors: Ungelenk Johannes
Published: April 2020

This article looks at Émile Zola’s novel cycle Les Rougon-Macquart and argues that it describes its subject, the Second Empire, as a warming climate tending toward climate catastrophe. Zola’s affinity to the notion of climate is shown to be linked to his poetic employment of the concept of ‘milieu’, inspired by Hippolyte Taine. Close readings of selected passages from the Rougon-Macquart are used to work out the climatic difference between ‘the old’ and ‘the new Paris’, and the process of warming that characterises the Second Empire. Octave Mouret’s department store holds a special place in the article, as it is analysed through what the article suggests calling a ‘meteorotopos’: a location of intensified climatic conditions that accounts for an increased interaction between human and non-human actors. The department store is also one of the many sites in the novel cycle that locally prefigure the ‘global’ climate catastrophe of Paris burning, in which the Second Empire perishes.
Talking about the Weather. Roland Barthes on Climate, Everydayness, the Feeling of Being, and Poetics
Authors: Buettner Urs
Published: April 2020

The paper reads Rolands Barthes’ considerations on weather and climate in his last lecture cycle La Préparation du Roman by contextualizing its brief remarks with his previous discussions on this topic. Barthes develops a phenomenological concept of climate, showing how experiences of place across the seasons shape certain habits. These manifest in expectations, perceptions, daily routines, and language. However, his particular interest is devoted to the question of how an existential experience of weather in its contingency can be regained. Furthermore, he investigates how poetry tries to capture the uniqueness and singularity of respective weather appearances against the patterns and narratives of the climate sedimented in the language system.

Diversity-oriented synthesis of 17-spirosteroids
Authors: Laroche Benjamin , Bouvarel Thomas , Louis-Sylvestre Martin , Nay Bastien
Published: April 2020

A diversity-oriented synthesis (DOS) approach has been used to functionalize 17-ethynyl-17-hydroxysteroids through a one-pot procedure involving a ring-closing enyne metathesis (RCEYM) and a Diels–Alder reaction on the resulting diene, under microwave irradiations. Taking advantage of the propargyl alcohol moiety present on commercially available steroids, this classical strategy was applied to mestranol and lynestrenol, giving a collection of new complex 17-spirosteroids.
Fuzzy logikát alkalmazó vonalkövető autó viselkedésének vizsgálata
Authors: Könczöl Boldizsár , Gál László
Published: April 2020

A fuzzy logika mindennapi használata nem újkeletű dolog. Meglepő, de szinte mindenki használta már, amikor például nagyon hideg, hideg, kicsit hideg, kicsit meleg, meleg, nagyon meleg, forró szavakkal illetett bizonyos dolgokat. Tudományos Diákköri dolgozatomban egy Arduino Uno vezérlő és néhány érzékelő segítségével sikeresen megvalósítottam egy vonalkövető autót, amely fuzzy logikán alapul. Ezen logikáknak többféle implementációja is van, és célom megmutatni, hogy az általam választottak mennyire használhatók a vonalkövetés során, van-e köztük látványos különbség.
relation éducative, au carrefour du social, de l’institutionnel et de l’affectif
Authors: AMMOR Samira
Published: April 2020

Cette contribution questionne, sur un plan épistémologique, le fonctionnement des inégalités sociales à l’école et les facteurs qui interfèrent pour les accentuer au niveau scolaire ou, au contraire, les limiter. Dans cette analyse, un premier focus sera porté sur le déterminisme social en tant qu’approche expliquant cette reproduction. Nous questionnerons, alors, son fonctionnement au niveau de l’école. Comment interfère-t-il avec le contexte scolaire ? Quels sont les facteurs qui le renforcent ? Quels sont les facteurs qui le réduisent ? Comment s’articule-t-il avec l’effet institution, ainsi que l’effet enseignant dans la réussite des élèves ?
Dans un deuxième temps, nous aborderons la relation éducative en tant que variable des performances scolaires agissant au croisement entre le social, l’institutionnel et le psychoaffectif. Nous interrogerons, pour cela, les déterminants de la relation entre enseignants et élèves, leurs modes interactifs, et leurs répercussions sur la réussite, ou l’échec, des élèves. Comment fonctionne la relation au niveau des représentations et attitudes des enseignants vis à vis de leurs élèves ? Par quels mécanismes et quelles interférences avec les facteurs sociaux et institutionnels ? Comment se structure l’effet enseignant dans une institution scolaire inégalitaire ? Enfin, est-elle suffisamment agissante pour arriver à aiguillonner, dans certains cas, la destinée scolaire des élèves, au point d’exercer sur eux l’effet Pygmalion, ou au contraire développer un processus de résilience ?
Reforms Needed in Aged Patient’s Care
Authors: Rao Hamna
Published: April 2020

Today’s health workforce is constantly engaged to enhance the standards of healthcare services and ensuring comprehensive healthcare standards to the community. Queensland’s health workforce is Australia’s second largest health workforce (1) and serving proportionately in all areas of QLD, making efforts to make health better by making research, surveys and developmental planning in rural and regional areas. Aged Care is currently the most concerned health issue among OECD countries (2) as aged population continues to grow and it’s challenging for Australian health sector to meet the standards of quality care in provision of aged care health services. As per Australian Institute of Health and Welfare statistics it is projected that Australia will constitute 22% of aged population in next 30 years (AIHW).
