Published: December 2019

En la Sierra de La Juanita y la Cuchilla de las Águilas, cercanas a la localidad de Barker, se extraen  rocas ferruginosas destinadas a la industria del cemento.  La falta de continuidad lateral de los bancos constituye un problema para los productores, tanto en la planificación de la explotación como de la recuperación ambiental. Con el fin de contribuir a la solución o mitigar esta problemática se aplicaron técnicas geofísicas y a partir de ello se realizaron reinterpretaciones geológicas de las áreas. Sobre la base de la información de superficie se planteó la utilización de un método geofísico rápido y de bajo costo, consistente en mediciones de susceptibilidad magnética en las rocas de canteras seleccionadas. Comprobada la respuesta  positiva de los niveles ferríferos por sus valores elevados de susceptibilidad, se programó una exploración magnetométrica terreste en el área de influencia de las canteras, con el fin de evaluar su eficacia para detectar en el subsuelo capas con altos tenores de Hierro y ajustar el tratamiento de los datos para la obtención de resultados óptimos.

Authors: Pritasari Luqyana Amanta , Kusumasari Bevaola
Published: December 2019

This research aims to see how policy is formulated by policy actors. This study revealed how official policy actors and non-official policy actors can influence a public policy formulation because of its significant contribution. The research method used was a qualitative method with a case study approach to the policy of relocating shrimp farming in Bantul Regency. Analysis of actors and political strategy typologies, namely positioning strategies; power strategy; player strategy; and perceptual strategies were used in this study. The research found that bargaining power occurred between actors in the form of negotiations and each actor carried out his own political strategy. In addition, this study was expected to overcome the ignorance of various parties regarding the process behind the formulation of policy. The implication to many people was to inform that formulation makers were not only from government and its increased community involvement in policy formulation.

Populating Chemical Space with Peptides using a Genetic Algorithm
Authors: Capecchi Alice , Zhang Alain , Reymond Jean-Louis
Published: December 2019

In drug discovery one uses chemical space as a concept to organize molecules according to their structures and properties. One often would like to generate new possible molecules at a specific location in chemical space marked by a molecule of interest. Herein we report the peptide design genetic algorithm (PDGA, code available at https://github.com/reymondgroup/PeptideDesignGA), a computational tool capable of producing peptide sequences of various chain topologies (linear, cyclic/polycyclic or dendritic) in proximity of any molecule of interest in a chemical space defined by MXFP, an atom-pair fingerprint describing molecular shape and pharmacophores. We show that PDGA generates high similarity analogs of bioactive peptides, including in selected cases known active analogs, as well as of non-peptide targets. We illustrate the chemical space accessible by PDGA with an interactive 3D-map of the MXFP property space available at http://faerun.gdb.tools/. PDGA should be generally useful to generate peptides at any location in chemical space.
Accurate Prediction of the S1 Excitation Energy in Solvated Azobenzene Derivatives via Embedded Orbital-Tuned Bethe-Salpeter Calculations
Authors: Kshirsagar Aseem Rajan , D'Avino Gabriele , Blase Xavier , Li Jing , Poloni Roberta
Published: December 2019

By employing the Bethe-Salpeter formalism with a non-equilibrium embedding scheme, we demonstrate that the paradigmatic case of S1 band separation between cis and trans in azobenzene derivatives can be computed with excellent accuracy compared to experimental optical spectra. Besides embedding, we show that the choice of the Kohn-Sham exchange correlation functional for DFT is critical, despite the iterative convergence of GW quasiparticle energies. We address this by using a global hybrid functional, PBEh, with the amount of exact exchange fulfilling the Koopman’s theorem for DFT hence yielding an environment-consistent ionization potential.

This method yields the first vertical excitation energy of 20 azo molecules with a mean absolute error as low as 0.06 eV, up to three times smaller compared to standard functionals such as M06-2X and PBE0, and five times smaller compared to recent TDDFT results.

The employment of FTIR spectroscopy and chemometrics for authentication of essential oil of Curcuma mangga from candle nut oil
Authors: Khudzaifi M. , Retno S.S. , Rohman Abdul
Published: December 2019

The adulteration of high price oil such as essential oil of Curcuma mangga Val. (EOCM)
with lower price oil is common to get economical profit. This study was to investigate the
authentication of EOCM toward candlenut oil (CNO) using FTIR spectroscopy combined
with multivariate calibration and discriminant analysis. The selection of CNO as
adulterant oil model was due to its close similarity to EOCM in terms of FTIR spectra.
Besides, EOCM has similar color with CNO, therefore, CNO is potential adulterant
toward EOCM. Two multivariate calibrations of partial least square regression (PLSR)
and principle component regression (PCR) along with FTIR spectra (normal versus
derivatization) were optimized to get prediction models for quantification. The results
showed that the combination of PLSR and normal FTIR spectra at optimized
wavenumbers of 1614-1068 cm-1 was capable of predicting the levels of EOCM
adulterated with CNO. Discriminant analysis was also success to differentiate the
classification of EOCM and EOCM adulterated with CNO with accuracy levels of 100%.
Using FTIR spectroscopy for oil authentication is rapid, simple without any chemicals,
solvents, and sample preparation so that this technique is considered as a green analytical
method.

Authors: Irafahmi Diana Tien
Published: December 2019

The objective of this scoping review is to map the existing literature that asses the relevance of undergraduate auditing education to meet contemporary audit practice. The scoping review followed the protocol outlined by Arksey and O'Malley (2005) that has five main stages: (1) identifying the research questions; (2) identifying relevant studies; (3) study selection; (4) charting the data, and (5) collating, summarizing and reporting the results. The studies reviewed were selected from three electronic databases: Proquest, Taylor & Francis, and Science Direct within 25 years time span (1995-2019). The results of the scoping review indicated that the majority of the studies recognize a shift both in terms of content and pedagogy to keep its relevance to professional demand. The shift needs to more emphasize on content as a gap still exists between auditing educators and practitioners.
O Construtivismo Político: Uma Teoria Pública da Razão Prática/Political Constructivism: a public theory of practical reason
Authors: Maciel Everton Puhl
Published: December 2019

RESUMO: Esse trabalho tem por objetivo analisar o construtivismo político da Terceira Conferência da obra Liberalismo Político, de John Rawls. Especificamente, vamos tentar compreender como, limitando o universo de construção aos parâmetros estabelecidos pelo discurso político, podemos estender o alcance dos princípios acordados na posição original para uma comunidade muito mais ampla frente às doutrinas morais abrangentes. Demonstraremos o construtivismo político coerentista não em oposição ao intuicionismo moral utilitarista nem ao construtivismo moral kantiano, mas como capaz de absorver modelos com esse grau de razoabilidade. Isso será disposto através de uma justificação pública tanto do conteúdo quanto da forma do modelo adotado. Assim, o consenso sobreposto apresentado por Rawls é responsável direto pelo resultado democrático que esperamos de uma sociedade onde a publicidade ocupa espaço enquanto fato e possui um valor aceito como legítimo. Nosso método de trabalho envolve uma leitura analítica do texto e de comentadores pertinentes ao assunto proposto.ABSTRACT: This study aims to objective analyze the political constructivism of the Third Conference of the work Political Liberalism, by John Rawls. Specifically, we understand how limiting the universe of construction to the parameters by the political discourse, we can extend the reach of the principles agreed in the original position to a much larger universe in the face of comprehensive moral doctrines. We demonstrate what political constructivism no consistent as opposed to utilitarian moral intuitionism or the Kantian moral constructivism, but as capable of absorbing models with this degree of reasonableness.

Mathematical Modeling and Optimization of Milling Parameters in AA 5083 Aluminum Alloy
Authors: BAŞAR Gökhan , KAHRAMAN Funda , ÖNDER Ganime Tuğba
Published: December 2019

In this study, the selection of optimal cutting
parameters for face milling of 5083 aluminum was investigated in order to
minimize the surface roughness. Effect of selected parameters on the surface
roughness was analyzed by using analysis of variance (ANOVA). The mathematical
model was developed to estimate surface roughness in face milling process by
using Response Surface Methodology (RSM). Feed, spindle speed and depth of cut
were selected as input variables. The statistical analysis indicated that feed
and spindle speed have the most considerable influence on surface roughness.
After developed mathematical model, Desirability Function Analysis (DFA) was
performed to optimize the cutting parameters. The lowest value of surface
roughness (0.41 µm) was acquired at a feed of 3008 mm/min, a spindle speed of
5981 rpm and a depth of cut of 0.54 mm.
Performance analysis of grid-connected micro-cogeneration system based on the internal combustion engine
Authors: YAVUZDEĞER Abdurrahman , EKİNCİ Fırat
Published: December 2019

The
effective usage of energy is an important factor in our country and world. The
cogeneration system is one of the methods for the effective usage of energy. The
cogeneration system in recent technology is about 30% more effective in
reducing fuel consumption and carbon footprint compared to the power and heat
production efficiency for traditional systems feeding by fossil fuels. Over the
last decade, extensive research has been undertaken on the optimization and use
of low-capacity internal combustion gas engines in micro-combined heat-power
systems. Problems such as the technology used in the micro-cogeneration system,
fuel type and performance, efficiency of the system, utilization of different
fuel types, noise, emission, maintenance problems have not been solved yet. In
recent years, intensive studies have been carried out on the fuel cells that
are being used for the cogeneration system, but the cost and the low life span
of fuel cell cogeneration systems are preventing it from becoming widespread.
With the proposed system, it will be easily applied in small scale places such
as houses, offices, campuses, hospitals, shopping malls, and electricity and
heat production efficiency will be used effectively for low CO2
emission. In this paper, the integration of an internal combustion engine which
has 9.8kW and 1500 revolutions per minute (rpm) properties, a synchronous
generator and grid connection have been successfully achieved and the
performance results of the proposed system have been obtained by using
MATLAB/Simulink.
The Effect of Uniform Magnetic Field on Pressurized FG Cylindirical and Spherical Vessels
Authors: YARIMPABUÇ DURMUŞ , TEMO Anwr
Published: December 2019

The stress analysis of functionally graded thick hollow cylindrical and spherical pressure vessels under the effect of uniform magnetic field are examined. These pressure vessels are designed in such a way that the material properties and magnetic permeability are exponentially graded in radial direction, provided that the inner surface is pure metal and the outer surface is pure ceramic. The differential equations with variable coefficients obtained under these conditions are handled by both Complementary Functions Method and Pseudospectral Chebyshev Method. Benchmark solutions available in the literature for some special cases are used to confirm the results. The effects of different mixture and uniform magnetic field on stresses and displacement distribution are shown in graphical form.
Effect of Extensometer Usage on Obtaining the Force-Displacement Curve of the Adhesively Single Lap Joint
Authors: ÇALIK Ahmet , AKPINAR Salih
Published: December 2019

Structural adhesively
bonded joints are frequently used in many areas spearheaded by the industries
such as automotive, marine space, and aviation due to the great advantages they
provide. Besides, load capacities of adhesively bonded joints which have
different geometries, are generally determined experimentally. Being compatible
of experimental and numerical analysis of adhesively bonded joints in the means
of both load carrying capacity and displacement has a great importance. But,
one of the most common problems in comparison of experimental and numerical
analyses is in spite of the coherence of experimental and numerical analyses in
load carrying capacity, it is observed that in the means of the displacement
analysis, there is incompatibility between those analyses. In the present study,
force-displacement curves of the single-lap cohesively bonded joints are
obtained experimentally by using both strokes of two different tensile test
machines which have identical calibrated load cells and video extensometer.
Experimentally obtained result was compared with numerical analysis. In the
experiments, AA2024-T3 aluminium and two-component Araldite 2015 were used as
adherend and adhesive, respectively. As a result, there is considerable
difference between the force-displacement curves of the single-lap overlap
joints which obtained experimentally from stroke and video extensometer. Also,
being new or old of the tensile test machines which have identical calibrated
load cells varies the displacement curve of the joint. When the experimental
data were compared with the results of the numerical analysis, it is concluded
that, obtaining the force-displacement curves of joints by using video
extensometer is more accurate.
Finding Common Ground: The Need for Cooperation and Collaboration in the Spanish Natural Wine Industry
Authors: Fuentes Fernández Rosana
Published: December 2019

In fall 2018 and late spring 2019, five small natural wine producers in Spain pondered the potential for cooperation and collaboration in their segment of the wine industry. As these niche producers shared their common goals and challenges, they debated how to come to a consensus about pooling resources and working together to educate trade customers as well as the prospective natural wine consumer.

Providing an overview of the Spanish wine industry and the natural wine segment, this applied research paper uses comparative case studies to explore the potential of incorporating cooperative relationships that could help these producers grow their businesses, share farming and wine-making techniques, and educate consumers about natural wines. Similar to previous cooperative relationships undertaken in other wine-producing regions, co-opetition might not only perform branding and collaborative marketing and reward entrepreneurial activities in Spain’s natural wine sector, but also carry some downsides in terms of autonomy and control over decision-making.
OUN (B) (ORGANISATION OF UKRAINIAN NAZIONALISTIS) AND UIA (UKRAINIAN INSURGENT ARMY) INFORMATION AND PROPAGANDA ACTIVITIES AMONG POPULATION OF OCCUPIED TERRITORY OF UKRAINE
Authors: Vynogradov Stepan
Published: December 2019

The article deals with the issues of the anti-German information and propaganda activities of the Organization of Ukrainian Nationalists (Bandera) (further OUN (B) and the Ukrainian Insurgent Army (hereinafter — UIA) among the Ukrainian population during the Second World War (June 1941–1944). Responding to archival documents, the author notes the three main periods in the deployment of the anti-German information and propaganda activities of the OUN and the UIA. The first period — from June 1941 to the September conference of the OUN in 1941. The second period — from September 1941 to February 1943, in particular, to the third conference of UNO. The third period — from February 1943 until the final liberation of Ukraine from German invaders in 1944.The author highlights the main tasks of the anti-German information and propaganda activities of the OUN (B) and the UIA among the population of the occupied Ukraine. He concludes that, aspiring to oppose the German occupation regime, the underground of the OUN (B) and the UIA during the war created their own propaganda network, established a mass production of printed publications, solved the problem of propagandists, conducted active verbal propaganda, and introduced a new type of mass campaign — propaganda raids of the UIA.However, the anti-German propaganda of the OUN (b) and the UIA during all the time of its management had its own peculiarities that distinguished it from other propagandistic directions of Ukrainian nationalists.Despite the tangible advantage of the enemy in propaganda, OUN (B) and UIA persistently and consistently propagandised their ideas. The content of their propaganda activities was consistent with each specific stage of the OUN and UIA struggles, taking into account the peculiarities of national environments that were disseminated through informational and propaganda activities.

Published: December 2019

Wider adoption of open educational practices and inquiry-based learning (IBL) methods in schools brings many challenges for teacher training especially in the field of STEM. Young teachers have to acquire a large number of competences – knowledge, skills, and attitudes, in order to be able to design and implement innovative and enriching open learning experiences in STEM. Besides STEM expertise, teachers have to demonstrate autonomy, creativity, mastery of innovative learning methods, team- working and leadership skills. This makes defining, teaching and measuring teachers’ competences for applying IBL training on practice a complex and demanding task. The present research aims to investigate and determine a relevant and practice-oriented STEM teacher competence framework. The participatory field experiment step on the previous outcomes of the IBL project ELITe (Enhancing Learning In Teaching via e-inquiries)* and brought together STEM teachers, teacher trainers and researchers. This way, authors succeeded to identify three main groups of practice-oriented competences, including two levels of 44 sub-competences. These competences have been addressed within a competence-based pilot course in Moodle referring to IBL activities that can measure and improve STEM teachers’ competence. The outcomes of this field experience demonstrate that participatory methods for teachers’ training bring additional understanding, motivation and clarification and readiness for adoption of innovative open learning practices in the classroom.

Authors: Gomides Mabel Duarte Alves , Silveira Amanda Oliveira Soares Monteiro , Araújo Candice Cristina Quirino de , Resende Natália Pimenta
Published: December 2019

Nos últimos anos, o processo de educação médica sofreu transformações mundiais para se adequar às normas das diretrizes curriculares, as quais são condizentes às mudanças na política de saúde, socioeconômica e tecnológica. A fim de adequar o processo de ensino-aprendizagem a estas alterações optou-se pelas metodologias ativas que visam também a busca de um aluno ativo, auto aprendiz e capaz de construir seus conhecimentos. Dentro deste contexto realizou-se uma revisão integrativa para melhor discernimento sobre o tema. Este artigo objetivou realizar uma revisão sobre o tema “formação médica por meio do método da aprendizagem baseada em problemas (APB)”, pesquisando artigos nacionais, dos últimos 12 anos, da Revista Brasileira de Educação Médica com análise descritiva e qualitativa. Observou-se a redução das publicações a partir de 2014, embora seja crescente o número de escolas que aderiram às novas diretrizes curriculares.

Authors: Silva Raphaela , Dunck Danillo Augusto de Sousa , Mendes Maria Teresa Kelly Gomes Lopes de Souza
Published: December 2019

Entendendo a importância da educação alimentar e nutricional para crianças nos dias de hoje, no Brasil, desenvolveu-se um estudo com o objetivo de conhecer se a educação alimentar contribui para a saúde das crianças no país.  Dessa forma, foi feita uma revisão sistemática onde foram selecionados sete artigos publicados entre 01 de janeiro de 2015 a 01 de junho de 2019, nos idiomas inglês, português e espanhol e com critérios de exclusão como: artigos que não condiziam com o tema escolhido e artigos pesquisados fora do Brasil. Foram identificados lacunas em relação à temática, visto que não tem sido foco das pesquisas nos últimos anos o acompanhamento por parte de associações ou órgãos reguladores da educação alimentar e/ou nutrição dos alunos e seu rendimento escolar, um dos grandes objetivos das principais políticas públicas no Brasil para esse tema. Os achados desta pesquisa ainda podem servir de inspiração para que legisladores possam desenvolver a nível nacional, mecanismos institucionais e incentivos mais condizentes com as condições vivenciadas hoje pelas famílias, principalmente as de baixa escolaridade e renda, onde foram demonstrados nos estudos as maiores dificuldades na implementação de práticas saudáveis de alimentação.

Seven compounds were isolated from the leaves and fruits of Egyptian Withania somnifera dunal, (Family: Solanaceae). The identity of the compounds based on their spectroscopic data were as follows: two withanolides; withaperuvin C (1), phyperunolideF (2) and four lipids;1,2-di-O-palmitoyl-3-O-(6´´´-sulfo-α-D-quinovopyranosyl)-glycerol (3), vaccenic acid (5), 1,3 dicaproyl,2-vaccenoyl-glycerol (6), vaccenolymonoglyceride (7) and β-sitosterol glucoside (4). All the isolated metabolites except (4) were reported for the first time from this plant. Besides, this is the first report for isolation of compounds (6, 7) in a pure form from a natural source. Different fractions of the fruits of the Egyptian plant were investigated for their anticholinesterase activities where the most potent ones found to be the aqueous, the light petroleum fraction in addition to a mixture of lipids.
Removal of Cr(VI) ions using a binary grafting of N-vinylcaprolactam and N,N -dimethylacrylamide onto crosslinked chitosan, synthesized by gamma radiation
Authors: Patiño Zaira , Ortega Alejandra , Burillo Guillermina
Published: December 2019

Chitosan is characterized by its good affinity of metal ions due to high amount of amino groups. However, crosslinking of chitosan results in a dramatic decrease of retention properties due to reaction of amino groups during process. N,N-dimethylacrylamide (DMAAm) increases the hidrophilicity of the system and improve the apparent mechanic properties; while N-vinylcaprolactam (NVCL), a temperature stimuli sensitive monomer with a LCST of about 32 oC, makes possible for reuse the material. Adsorption of Cr(VI) onto crosslinked chitosan (net-CS) and NVCL/DMAAm binary grafted system onto net-CS, synthesized by gamma radiation of 60Co, has been investigated. The experimental results obtained from equilibrium adsorption studies are fitted in Langmuir and Freundlich isotherms. The Langmuir model agreed better, indicating that adsorption process is carried out homogeneously onto surface. The maximum adsorption capacity was 24.63 and 55.2 mg g-1 for net-CS (1%) and net-CS (3%), respectively. The maximum retention was obtained from the binary grafted system (21%) onto net-CS (3%) with 142.86 mg g-1.

Two recent books try to redefine the economic and financial systems bringing them back to documents (Ferraris) and to instinctive drives (Mazzarella). This essay reviews some of the most important novels of the third millennium about entrepreneurs to test the cogency of these concepts. From American Pastoral by Philip Roth to Beautiful You by Chuck Palahniuk, from The Human Resources Manager by Abraham Yehoshua to Zero K by Don DeLillo, the essay describes the present world as a society of wasted desire and the life of the company as a constant search for meaning.

This article aims to offer a review of the possibilities offered by a ‘narrative’ approach to examine the succession in businesses through some meaningful examples. In the first part, the focus is on a strictly literary representation, i.d. the novel Il padrone by Goffredo Parise (1965), which is still relevant to date for its extraordinary attention (and artistic outcome) on dynamics in a family business context. In this novel the notion of ‘personal myth’ fulfils a particular role, with all its consequences for the business. In the second part, it is shown an obviously incomplete series of case-studies in which economists use literary techniques and tools to represent and/or analyse business intergenerational transition, especially in family business. In the third part, one of these studies – focused on the Berger family case – is examined more deeply to understand its theoretic choices and its scientific accomplishments, in order to wish for a real multidisciplinary approach to this topic, involving literary critics, theorists and linguists.

The Valuation of Financial Derivatives Subject to Counterparty Risk and Credit Value Adjustment
Authors: Xiao Tim
Published: December 2019

This article presents a generic model for pricing financial derivatives subject to counterparty credit risk. Both unilateral and bilateral types of credit risks are considered. Our study shows that credit risk should be modeled as American style options in most cases, which require a backward induction valuation. To correct a common mistake in the literature, we emphasize that the market value of a defaultable derivative is actually a risky value rather than a risk-free value. Credit value adjustment (CVA) is also elaborated. A practical framework is developed for pricing defaultable derivatives and calculating their CVAs at a portfolio level.
