Este artigo apresenta um recorte da pesquisa de mestrado sobre a manipulação das barras de calcular descritas por John Napier no tratado Rabdologiae de 1617. Objetivando a identificação de potencialidades didáticas que venham a construir interfaces entre a história da matemática e o ensino. A forma como desenvolvemos essas potencialidades ocorre dentro de um processo de compreensão histórico-cultural da época em que o tratado foi escrito e como o autor foi influenciado durante todo o processo. Fizemos uma rápida apresentação do tratado e do conteúdo, com destaque para a parte que iremos tratar no artigo. Trata-se de uma pesquisa bibliográfica, participativa. No tratado, escolhemos um dos instrumentos contidos e as orientações para sua construção e manipulação, para o desenvolvimento das atividades. Essas foram aplicadas aos participantes de um curso de extensão universitária, que foram observados e tiveram suas opiniões e impressões registradas para posterior análise. Das práticas realizadas, descrevemos a aplicação de uma delas, a que faz a apresentação do instrumento, conforme as orientações de John Napier (1550-1617), para sua construção e preenchimento. Apresentamos as impressões desses participantes ao primeiro contato com o instrumento e como eles descreveram a mobilização de conceitos matemáticos. Concluindo que o instrumento possui diversas outras potencialidades didáticas, além da habitualmente utilizada, que é para a realização da operação de multiplicação.

Published: January 2020

Total of 124 species of the aphyllophoroid fungi have been found in the tundra and forest-tundra vicinities of Tiksi and Novosibirsk Isles (Arctic Yakutia). Only 6 species were collected in native conditions of «high Arctic» (northern Arctic tundras), 5 of them belonging to the clavarioid morphological group (83.3 %). The species composition of aphyllophoroid fungi in other subzones of tuntra («low Arctic») is presented in our collections by 46 species, including 56 % of clavarioid and 37 % of corticioid species, poroid and thelephoroid morphological groups making less than 5 % both. 114 species were found in the forest-tundra zone, half of them are corticoid fungi (49 %), whereas the ratio of clavarioid ones is 27 %, that of poroid ones 22 %, and that of thelephoroid ones not over 2 % of species. Similar tendencies in changing the roles of different morphological groups under zonal gradient were described during analysis of the Urals and Mid-European aphyllophoroid fungi too.

This research develops and implements methods for calculating lighting systems for classrooms in the Khairul Ummah Boarding School. The lumen is used to determine the number of luminaires needed to improve lighting quality following SNI 6197:2011. The number of luminaires obtained from this study was entered into the DIALux Evo 8.1 software. The results obtained of this study indicate that the lighting in the classroom at Khairul Ummah Boarding School didn’t reach the recommended standard, the direct measurement results of the average lighting level of class A was 10.79 lux, while the class X-IPA-3 was 11.66 lux. To improve this condition, class A requires 15 luminaires, and X-IPA-3 requires 12 luminaires. The difference in the results obtained from the two calculations for class A is 0.6%, and X-IPA-3 is 3.4%. Investment costs are needed to improve the lighting system in these classes worth Rp.2,700,000.00 to provide 27 lamps.
Applied Theatre and Education: We Are Not-Yet …
Authors: Prendergast Monica , Saxton Juliana
Published: January 2020

In this article, we consider the relationship between education and applied theatre, the growth of applied theatre curricula within Canada, the issues that presently we identify as ‘productive tensions,’ and political and social concerns that now frame the ways in which we shape and conduct our practice. Our thoughts and suggestions, while limited by those constraints we offered above, may serve to open a space for discussion on what is and what might be. In our view—looking back over two decades of development in the field of applied theatre programs in Canada—there are a number of tensions that have come into clearer focus as applied theatre has been finding its feet. We see these tensions as productive and offer them not as criticisms but as opportunities to reconsider methodologies in light of a post-dramatic world. Applied theatre programs tend to operate in theatre departments that mostly focus on training for independent careers in text-based mainstream theatre. Such an intention may make it difficult for some who see theatre as a path to careers different from performance and/or production. Certainly, the recent addition of applied theatre to university curricula has revealed some interesting pressures. The division between the hierarchical traditions of theatremaking, with the top-down approach of director-designer-actor-audience, may be beginning to shift with the advent of new thinking. The ways of working that are integral approaches to applied theatremaking require a broader interdisciplinarity of courses than those traditionally offered in departments of theatre.
Evolving with the Times: Applied Theatre and Performances of Immigration and Settlement
Authors: de Guevara Lina
Published: January 2020

This article is an overview of Lina’s work in Canada since arriving as an immigrant from Chile in 1976. As an actor and director, she became increasingly concerned with expressing social and cultural issues related to the immigrant condition, such as alienation, racism, family violence, loss of identity, and disconnection from culture. She observed these conditions in her Latin American immigrant community and in 1988 founded Puente Theatre to look for solutions and to add immigrant voices to the Canadian theatre panorama.
Early Poverty and Future Life Expectancy with Disability among the Elderly in Argentina
Authors: Monteverde Malena , Palloni Alberto , Guillén Montserrat , Tomas Silvia
Published: January 2020

Two aspects of the aging process in Latin America should be specially taken into account in order to evaluate future perspectives of morbidity among the elderly in the region: 1) Cohorts who will compose the bulk of the elderly population in the 21st century in Latin America survived to old age largely because of improvements in medicine and to a much lesser extent to amelioration of living standards, as it is the case in high income countries, and 2) a high proportion of the Latin American population still live in poor economic conditions and even these vulnerable individuals continue to experience gains in (adult and older adult) survival. We aim to evaluate to what an extent recent levels of poverty and indigence among young children in Argentina could impact future levels of disability and demands for long-term care of older people. Our results show that given the levels of poverty and indigence in childhood observed between 1988 and 1994, the relationship between poor early conditions, and the risk of being disabled among the elderly in Argentina, life expectancy with disability at age 60 years old would increase substantially between 2000 and 2040, both in absolute and relative terms.

Authors: Freire Flávio Henrique Miranda de Araújo , Gonzaga Marcos Roberto , Gomes Marília Miranda Forte
Published: January 2020

O método de relação de coortes é um método demográfico utilizado para projeções populacionais por sexo e idade para pequenas áreas. Porém, devido a instabilidade dos eventos demográficos em áreas menores, o método produz resultados pouco razoáveis para alguns grupos de idade. Neste artigo aplicamos um estimador contração, bayesiano empírico, para reduzir a instabilidade nas estimativas dos fatores diferenciais de crescimento do método em áreas menores. Ao aplicarmos o método de relação de coortes, ajustado pelo bayesiano empírico, para projeções populacionais municipais no Brasil entre 2000 e 2010, observamos uma redução na variabilidade das estimativas por idade. Além disso, o método reduziu o erro percentual absoluto médio das populações projetadas nesse decênio comparativamente aos resultados obtidos com a aplicação do método original proposto por Duchesne (1989), especialmente nos grupos etários de adultos e idosos.

Fluid flow in the impulse valve of a hydraulic ram
Authors: Sobieski Wojciech , Grygo Dariusz
Published: January 2020

The paper presents the results of a study investigating the equilibrium of forces acting on the closing element of the impulse valve in a water ram at the end of the acceleration stage. Acceleration is one of the three main stages in the working cycle of a water ram. In the first part of the paper, we estimated water velocity based on our earlier experimental measurements. We also calculated the minimum force required for closing the impulse valve. The second part of the paper discusses two variants of a numerical model, which was developed in ANSYS Fluent to determine the result-ant hydrodynamic pressure and, consequently, the forces acting on the head of the impulse valve at the end of the acceleration stage. The main aim of this research was to verify the applicability of numerical modeling in water ram studies. The present study was motivated by the fact that Computational Fluid Dynamics is very rarely applied to water rams. In particular, we have not found any numerical studies related to the equilibrium of forces acting on the closing element of the impulse valve in a water ram.

The paper presents construction solutions for guiding a single-sharp barrel drill blade during drilling deep holes, with an analysis of construction and technological problems for two ways of inserting the drill into the processed material in the first stage of drilling - using a pilot hole or guide sleeve.
During the implementation of the technological process of deep drilling of holes with barrel drills using a vertical numerical milling machine FNE 40NC AVIA, the kinematics of the object-tool system (P-N) and other technological parameters affecting the execution of pilot holes in strictly defined technological operations were analyzed.
The course of operational tests carried out using two types of cooling-lubricating agents - Milpro HG12 oil without and with the addition of ultra-dispersive copper particles and copper oxides (0.05 ÷ 0.6 µm), Panther GP-1 (PWPH PantherOil Poland) in a ratio of 1 to 100 is characterized.
Based on the performed drilling of through holes in 1.0503 steel with EB80 drills with a diameter Dc = 8 mm, made of cemented carbide K15 (WC 94%, Co 6%), the course of wear of the barrel drill blade on the total drilling path Lw = 8000 mm for 112 was determined through holes and Kw geometric wear indicator of the drill bit.
The obtained results of wear were compared with the results of tribological tests. with the use of cooling lubricants, under the conditions of friction involving 1.0503 steel with tungsten carbide, of chemical composition as K15. The material and technological conditions of abrasive wear of a particular friction pair are the same as for operational tests of the barrel drill blade wear at deep hole drilling.

Published: January 2020

Aims and objectives: This study was done to evaluate the functional and radiographic outcome of PFN in treatment of proximal femoral fracture and more common technical, mechanical complications and intraoperative difficulties during the implant implementation.

Materials & Methods: We conducted a retrospective study with ten cases of proximal femoral fractures treated between September 2017 and September 2018, which were accepted at the Department of Orthopedics, the University Hospital of Trauma and the American Hospital in Tirana. Fractures are classified according to classification AO and Boyd-Griffin. The age range of patients taking the study was 20-90 years. Ten cases were followed at regular intervals and the final assessment was made at the end of the 6 month period. In the result, functional clinical assessment according to Harris hip score was done .

Results: In our study,mean age was 66 y.o, 7 male and 3 females. Mean of hospitalization time 6 days, mean operation time 120 min. In our study at 6 months follow up, union was achieved in 9 cases, open reduction was performed in 3 cases (10 cases). Technical and mechanical complications were noted in one case. Reoperation rate was 10 % (one case). According Harris hip scoring system excellent results were seen 40   % of cases (4 cases), good results in 50 % cases (5 cases),  and poor results in 10% cases (1 case).

Conclusions: In our study, in spite of low experience in proximal femoral nailing in cases with unstable trochanteric / subtrocanteric fractures, it was found that PFN is an attractive implant and suitable for proximal femoral fractures and its use in unstable trochanteric / subtrocanteric fractures is very encouraging. This study has also shown that this device can safely be used by an average surgeon to handle common but sometimes tough fractures. Operation is technically not difficult, but gradual learning and great patience is needed to make this method really minimal invasive.

The features of the formation of a portfolio of projects following the energy-saving strategy of metallurgical enterprises are considered. As a result of the analysis of the energy-saving program structure at the metallurgical enterprises, it was found the problems that are solved by the energy-saving projects are inefficient consumption (significant losses) of energy resources (gas, thermal energy, electricity), control over the costs formation and the results of improvements in energy consumption. The overall goal of improving energy efficiency at the enterprise is realized through the management of an energy-saving project portfolio, which is aimed at fulfilling the following tasks: optimization of energy balance; minimization of natural gas consumption; optimization of energy efficiency, etc. Success criteria for an energy-saving project include efficiency; operating costs, losses, etc. It should be noted that it is difficult to objectively estimate the share of each energy resource in the total flow, to determine the energy intensity of individual production, departments, and the whole enterprise, etc. We propose the concept of managing a portfolio of energy-saving projects, which is based on several interconnected adaptive systems: planning and building, monitoring and change management. To establish priority problems, a necessary and complete analysis of the economic trends formation, to characterize the process of formulating the fuel-energy balance of metallurgical enterprise. A system model for the formation of a portfolio of energy-saving projects of a metallurgical enterprise is presented. We describe a mathematical model of project selection is described, which comprehensively takes into account the current state of the enterprise and its future strategic areas of work, resource and financial support for projects and risks. The use of this model allows a consistent analysis of portfolio projects to identify the possibility of their implementation at a metallurgical enterprise, coordinate project implementation plans and plans of the enterprise at different levels of planning, select the most promising projects for implementation following a defined energy strategy.

Published: January 2020

In the context of Aceh, the word “Ulama" refers to an Islamic scholar who own boarding school (In Aceh language known as Dayah) or a leader of an Islamic boarding school (known as Teungku Dayah). Ulama become "the backbone" of any social problem and play strategic and influential roles in Acehnese society. However, The Ulama roles have changed in the post-conflict era in Aceh. The assumption that Ulama are unable running their authorities in Acehnese society especially in the post-conflict era. Ideally, their roles are needed in the reconciliation regarding the agents of reconciliation who have authority like the Ulama and are trustworthy by Acehnese society. Therefore, this article aims to discuss the position of Ulama in the process of post-conflict reconciliation in Aceh. To investigate the problem, a descriptive qualitative method was used, where the method is to describe the nature of a temporary situation that occurs when the research is carried out in detail, and then the causes of the symptoms were examined. The data were literature studies, participatory observation, and in-depth interviews. The results of this research showed that during an important period of Aceh's history, the Ulama constantly become guardians that provide a religious ethical foundation for each socio-political change in Aceh, and subsequently they also act as the successor to the religious style that developed in the society. Even the formation and development of the socio-political and cultural system occurred partly on the contribution of the Ulama. The position of Ulama in the process of post-conflict reconciliation in Aceh can be found in four ways. Firstly, knowledge transmission. Secondly, as a legal decision-maker which refers to Sharia law, especially related to the reconciliation process. Thirdly, as a mediator. Fourthly, cultural roles in the form of ritual or ceremonial guides that are carried out when the parties of the conflict have met an agreement to reconcile.

Plant breeding, associated with other areas, as well as the registration and protection of cultivars, have brought relevant contributions to turn soybean into one of the most important crops for the Brazilian agribusiness. Potential additional soybean descriptors for cultivar protection purposes such as the length of the hypocotyl and epicotyl have been reported in the literature. Thus, the objective of this work was to study the effect of soil volume, plant density per pot and crop and cultivar depth on the length of the hypocotyl and epicotyl and the height of soybean seedlings. The study conducted 4 experiments, in which the length of the hypocotyl and epicotyl and the height of soybean seedlings were evaluated at the V2 and V3 stages. Experimental units were submitted to pots with three volumes of soil (1, 2 or 3 dm3), three quantities of plants per pot (1, 2 or 3), three sowing depths (1, 2 or 3 cm) and four cultivars [TMG 4185, BRSMG 68 (Vencedora), BRS 7980, BRS 8381]. Results showed that soil volume, plant density and sowing depth had no effect on hypocotyl length evaluated at the V2 stage and that sowing depth had no effect on epicotyl length. However, soil volume, plant density, sowing depth and cultivar variations had an influence on plant height, and the soybean cultivars showed distinguishability for hypocotyl and epicotyl length at the V2 and V3 stages, being considered potential soybean descriptors.

The gill nematode (Meloidogyne spp.) is a widely distributed phytoparasite capable of causing great yield losses in the most diverse cultures. Therefore, the objective of the present work is to evaluate the effect of Bacillus amyloliquefaciens used in the treatment of seeds as a biocontrol agent of Meloidogyne javanica in common bean, and the direct effect of M. javanica on hatching, motility and in vitro mortality. Experiments were conducted in the municipality of Cascavel, Paraná, in a greenhouse and laboratory. A randomized complete block design (DBC) was used, using five different doses of the biocontrol (0, 50, 100, 150 and 200% of the recommended dose), with five replicates for both experiments. The sowing of 3 seeds of cv. IPR Bullfinch was performed in 2 L plastic vessels with autoclaved soil and sand mix. The inoculation of 2000 eggs / J2 of M. javanica per plant was carried out in a sequence. Forty days after inoculation, the plants were removed for evaluation, where vegetative parameters and nematological parameters were analyzed. In the laboratory bacterial / nematological suspensions were added totaling 10mL per plate. Hatching in distilled water was used as control. The chambers were maintained in B.O.D. to 27 +/- 1º C with photoperiod of 12 hours / light. Hatching, motility and mortality were evaluated at 9 and 15 days. Both data were subjected to a regression analysis at 5% probability level, using the statistical software SISVAR, version 5.6. Results showed that the bacterial isolate B. amyloliquefaciens is a potential controller of M. javanica "in vitro", as well as of “in vivo" vegetative and nematological parameters.

In search for a more sustainable agriculture, the use of microorganisms as a technology is increasingly being used by agriculture throughout the world. This is due to the fact that it minimizes the use of agricultural supplies reducing environmental costs and impacts, based on the beneficial and natural relationships between edaphic organisms and cultivated plants. The rhizobacteria habitat in the soil establishes biochemical relationships with the plants acting as plant growth promoters (PGPR). Many of these bacteria are producers of phytohormones and enzymatic compounds with the capacity to provide important nutrients for plants. In this context, the present work aimed to quantify the potential of indole-3-acetic acid (IAA) production and the phosphate solubilization of rhizobacteria from Western Paraná. Isolates grown in DYGS medium plus tryptophan were quantified by colorimetry for the production of IAA. Iron phosphate solubilization was carried out by inoculation in modified Pikovskaya medium (PKV) and quantified by colorimetry. The results were evaluated by the Scott-Knott test at 5% using the SASM-Agri program. The highest IAA production was observed with the addition of tryptophan to Erwinia (219); Enterobacter (302) and Salmonella (57). Isolates Falsibacillus (438) and 505 showed higher efficiency in the iron phosphate solubilization. Isolates Enterobacter (130), 438 and Enterobacter (151) were highlighted in both tests, being characterized as a great potential for use in biotechnological products.

Agricultural year and harvesting season may interfere with yield and post-harvest performance of table cassava cultivars, with consequences for their commercialization and net profit. The objective of this work was to quantify the effects of harvesting season and agricultural year on yield performance of table cassava cultivars and their correlations. Planting was carried out in September in two consecutive years near Londrina city, PR, in a Clay-textured Oxisols red eutrophric. The experiment followed a randomized complete block design (RCBD) with four replications, consisting of seven harvesting times (8, 10, 12, 14, 16, 18 and 20 months after planting) for each agricultural year. The table cassava cultivars used were: Catarina Amarela, Catarina Branca, Mato Grosso, Pretona, IAPAR 19-Pioneira and IAC 576-70. The following agronomic characteristics were evaluated: number of roots per plant, length, diameter and yield of tuberous roots, as well as the following post-harvest characteristics: net yield and peeling time per kg of each cassava genotype. The cultivars, harvesting time and agricultural year affected the yield and post-harvest characteristics. ‘IAPAR 19-Pioneira’ presented a larger number of roots per plant (9.9) and peeling time (224.8 seconds.kg-1), but lower yield % (66.2%) and diameter of tuberous roots (4.0 cm), regardless of harvest time and year of planting. 'Catarina Amarela', 'Catarina Branca', 'IAC 576-70' and 'Pretona' provided higher yields, diameters and reduced peeling times. The root mean diameter is one of the characteristics that can be used as a selection criterion in a table cassava genetic breeding program: the larger the root mean diameter the larger are tuber root yield and percentage of weight of the tradable part of the roots, and the lower is the time of peeling.

Purpose - This study examines the volatility spillovers in the presence of structural breaks with specific reference to South Asian Capital markets. The global financial crisis of 2007-2009 has compelled policymakers to realize that financial instability has the potential to threaten economic stability and growth; therefore, managing the financial crisis is inevitable. To manage the impact of financial crises, understanding the dynamics of volatility spillover across various markets is imperative. This study has investigated the possible emergence of structural breaks in risk patterns after global financial crises in south Asian markets. Methodology - Using the data from July 2002 to June 2016, employing the Exponential GARCH methodology. Findings - This study finds a significant volatility spillover after the financial crisis of 2007-09. Therefore, the existence of a structural break in the risk pattern of south Asian capital markets cannot be fully rejected. Policy Implications - This conclusion is of prime importance to policymakers in devising policy guidelines concerning financial crises.

La productividad de plantines de calidad constituye una estrategia para asegurar la supervivencia y el desarrollo y de esta manera enfrentar los cambios naturales y los ocasionados por la actividad humana que ponen en peligro diversas especies forestales. El objetivo de esta investigación es describir morfológicamente las respuestas de variedades de J. neotropical a las disoluciones nutritivas de N P K. Esta investigación es experimental, descriptiva y con enfoque longitudinal que estableció un diseño en bloques completos al azar (DBCA) con 262 observaciones, se evaluó el desarrollo del crecimiento en 65 días desde los 30 días después de haberse sembrado; se tomaron medidas de incremento de altura y el incremento del diámetro del tallo de las plantas. Se realizaron análisis estadísticos descriptivos, de dispersión y tendencia central, análisis de varianza, y se ejecutó un clúster para determinar agrupaciones de patrones de crecimiento respecto de las procedencias. Se encontraron diferencias significativas a la respuesta de las plantas y donde T6 obtuvo los mejores resultados en altura y en diámetro. Se concluyó que el mejor tratamiento es T6 y respecto de las procedencias P4 tiene los mejores valores de crecimiento, estos resultados difieren del testigo y de otros autores. El procedimiento clúster por medio de la vinculación de Ward a través de la distancia Euclidiana agrupó las tendencias de crecimiento en tres grupos sin encontrarse factores de incongruencia. La prueba de Chi-cuadrado de Pearson demuestra que los tres grupos encontrados pueden asociarse con la respuesta morfológica de J. neotropica de distintas procedencias a los tratamientos. Se recomienda estudiar la genética de estas variedades de J. neotropica para demostrar si la procedencia ha generado sub variedades con perfiles de crecimiento y necesidades nutricionales diferentes.

Background: 80% of people with a stroke have impairment of the upper limb (UL). The hemiparetic arm is one of the most devastating consequences after stroke. Improving use of the affected UL is important however, because difficulty in using this UL in daily tasks has been related to lower quality of life.

Design: A prospective randomized control trial type study.

Setting: Malaysia Government and Private Hospitals and also in private Physiotherapy Centre’s.

Population: A total of 25 subjects post stroke were randomly assigned to either in experimental group (n=13) and control group (n=12).

Methods: Control group received 45 minutes of treatment session and therapy consisted of conventional therapy only with the affected upper extremity whereas experimental group also received 45 minutes of treatment session and therapy consisted of conventional therapy along with mirror therapy for three days/week. Outcome measures used were Fugl-meyer assessment and Functional independent measure.

Results: Comparison of the changes in the Fugl-meyer assessment and Functional independent measure from baseline to six weeks between control and experimental group, revealed that significant improvement were in experimental group which was (p<0.05).

Conclusion: Combination of conventional and mirror therapy is an effective method on restoring upper limb motor function among hemiplegic patients.
