Authors: Jahed Armaghani Danial
Published: July 2018

Reliable estimation of rock fragmentation is an important issue in the blasting operations in order to predict quality of the production. Since rock fragmentation is affected by various parameters such as blast pattern and rock mass characteristics, it is very difficult to have an appreciate prediction of it. This paper describes a new hybrid imperialism competitive algorithm (ICA)-artificial neural network (ANN) in order to solve shortcomings of ANN itself for prediction of rock fragmentation. In fact, the influence of ICA on ANN results was studied in this research. By investigating the related studies, the most important parameters of ICA were identified and a series of parametric studies for their determination were conducted. All models were built using 8 inputs and one output which is rock fragmentation. To have a fair comparison and show the capability of the new hybrid model, a pre-developed ANN model was also considered and constructed. Evaluation of the obtained results demonstrated that a higher ability of rock fragmentation prediction is received developing a hybrid ICA-ANN model. Coefficient of determination (R2) values of (0.949 and 0.813) and (0.941 and 0.819) were obtained for training and testing of ICA-ANN and ANN models, respectively which indicated that the proposed ICA-ANN model can be implemented better in improving performance capacity of ANN model in estimating rock fragmentation.

Un viaje por los senderos, rituales y vivencias gerencia cultural de turismo en sitios arqueológicos.
Authors: Rico Ramírez Mónica Sofía
Published: July 2018

Que es el viaje, sino la posibilidad de encuentros con significados y representaciones que se van volviendo experiencia? Distintivamente, en esta era de la posmodernidad, el concepto que esta imperando es el de Turista, un concepto de naturaleza comercial, donde la finalidad es establecer intercambios comerciales, con un pago económico, en torno a las visitas o recorridos, no necesariamente planeados.

Practicas cotidianas que se vuelven políticas turísticas, atractivas por los ingresos de dinero, donde se propone atraer a la mayor cantidad de visitantes durante cada temporada, asociada a festividades, celebraciones religiosas, muestras gastronómicas, en si, todo lo que la cultura posibilite como atractivo de celebrar, conmemorar, conocer o simplemente algo nuevo que ofrezca una ruptura de la soledad, como acompañante.O el encuentro de vivencias que adquieren significado.

La riqueza del turismo cultural en Colombia, envuelve diversidad de factores: naturales, ecológicos, y sociales que permiten comprender comportamientos, rituales, creencias y fenómenos de la cultura social, lo que genera identidad que apropia una persona o una comunidad, al reconocerse con territorios patrimoniales como: “El Teyuna”, “el lava patas, o el Templo del sol”, “el auka Wasi”, “dantayako”, entre otros. La ley General de Cultura, 1185 de 2008, menciona que el patrimonio cultural de la Nación está constituido por todos los bienes materiales, las manifestaciones inmateriales, los productos y las representaciones de la cultura que son expresión de la nacionalidad colombiana.

Por tanto, las costumbres, la gastronomía, los festivales, saberes y tradiciones, representaciones de patrimonio material e inmaterial, ingresan entre las representaciones culturales que identifican y dan valor cultural a la creencia de las personas, de una sociedad. Entre los aspectos que fortalecen el turismo en Colombia, se da en gran medida y cada vez con mayor relevancia la gestión cultural y empresarial para promover y emprender escenarios de paz.

La apuesta exitosa para la generación empresarial a través del turismo de cultura en Colombia, se genera a partir de la diversidad de sus ecosistemas, de las comunidades emprendedoras, de la ausencia del conflicto, de los intereses colectivos, que se forjan con honestidad, conocimiento y coherencia, es allí cuando fructifica la creación empresarial, que parte de las iniciativas emprendedoras de un grupo de personas asociadas para ofrecer un producto, que marque la diferencia en lo que se ofrece (factor diferenciador), en la creación de ese producto, median unos principios y valores que se establecen como la cultura de una sociedad, lo más apetecido en el momento de ofrecer los servicios turísticos, lo que se palpa durante los viajes y recorridos, lo que consolida a la gente en comunidad que busca y compone la paz.
Diseño del programa de mejoramiento del sistema gerencial para generar una comercialización sostenible de papa común en el proceso de compra al interior de la corporación de abastos de Bogotá S.A.
Authors: Romero Infante Jaime Alberto , Castillo Gómez Edison Gerardo
Published: July 2018

La comercialización sostenible de alimentos perecederos hace parte de la responsabilidad social empresarial que desarrolla actualmente la Corporación de Abastos de Bogotá S.A CORABASTOS, dentro de su plan de desarrollo 2016-2025 que le permitirá posicionarse como la central de alimentos más importante del país y referente del mercado nacional. Dicha sostenibilidad está enmarcada dentro del proceso de compra, alistamiento y venta de productos perecederos, en donde se involucran las partes más importantes de la cadena y que no se limita exclusivamente al actor comercial que ejecuta su actividad dentro de la central. En este orden, se considera al productor, quien dentro de las actividades de post cosecha debe adoptar e implementar medidas activas tendientes a generar valor agregado, que minimice el impacto ambiental generado en el campo y permita a la central de alimentos como receptora del producto, mitigar los riesgos de alto impacto 
ambiental. Ahora bien, dentro del proceso de alistamiento del producto para la venta, el manejo de los residuos, su posterior aprovechamiento y el uso de aquellos no aptos para comercialización, pero si para el consumo, posicionan el proceso dentro de la central, generando preponderancia de la marca empresarial y ventaja competitiva. La venta del producto debe, aparte de las utilidades causar comportamientos responsables de consumo, como producto de la sostenibilidad pretendida.
El Diagnóstico empresarial y el plan de intervención permitieron de manera organizada, plantear la forma adecuada de llegar al diseño e implementación de un sistema gerencial, para lo cual fue necesario revisar y modificar apartes fundamentales del Reglamento Interno de Funcionamiento y de la misma estructura organizacional de la empresa, que basados en la política pública permiten su aplicabilidad y funcionabilidad, buscando el compromiso de los grupos de interés participantes en el proceso y que inciden de manera importante en el resultado esperado.
Con el desarrollo de un proceso metodológico de investigación de acción participativa, en tres fases: contacto con la comunidad, recolección y análisis de la información, con instrumentos cualitativos y cuantitativos, se busca generar propuestas de solución y de implementación, analizando la situación que vive cada uno de los actores que participan en el proceso, sus intereses, proyecciones y necesidades socio ambientales que orienten a la sostenibilidad del proceso.
El planteamiento y modelación de un esquema financiero participativo, permite generar ajustes periódicos que facilite el involucramiento de mas participantes, a la medida en que se materialicen los resultados.

Published: July 2018

O objetivo deste artigo foi conhecer as práticas do processo orçamentário realizadas numa viticultora do Vale do São Francisco, dada a ausência na literatura acadêmica sobre trabalhos correlatos, bem como certas empresas ainda não se valerem de tais práticas. Foi realizado um estudo de caso descritivo, com concepção filosófica pragmática, de forma corte seccional, numa fazenda viticultora de porte médio, com 10 anos de existência, escolhida pelo critério de acessibilidade. Empregou-se a entrevista semiestruturada e a pesquisa documental para a coleta dos dados. Os depoimentos foram interpretados pela Análise de Conteúdo, enquanto que os documentos contábeis foram analisados via fluxo de caixa. Emergiram duas categorias das falas dos entrevistados que refletem o estágio incipiente da fazenda quanto às práticas do processo orçamentário. Em seus fluxos de caixa realizados, uma destruição de valor financeiro da fazenda foi encontrada, consequência do estágio elementar das suas práticas orçamentárias. Portanto, pode-se dizer que a fazenda estudada não adota nenhuma prática documentada na literatura sobre o processo orçamentário, sendo guiada pela sua experiência empírica. Comentários de estudos futuros são ditos no final do artigo.

Authors: Dos Santos Tiago H. , Goedtel Alessandro , Da Silva Sérgio A. Oliveira , Suetake Marcelo
Published: July 2018

Os motores de indução têm grande importância nos mais diversos setores industriais por sua robustez e baixo custo. Assim, quando a carga acoplada ao seu eixo necessitar do controle de velocidade, parte das estratégias de controle e acionamento é baseada na estimativa de velocidade. A proposta deste trabalho consiste em apresentar uma metodologia alternativa às tradicionais para a estimativa de velocidade do motor de indução trifásico. Este é acionado por um inversor de tensão utilizando modulação espacial vetorial na estratégia de controle escalar baseada em redes neurais artificiais. Resultados de simulação e experimentais são apresentados para validar o método proposto com o motor submetido a variações de velocidade e torque de carga, os quais demonstraram ser bem promissores.
Influence of power converters on PV maximum power point tracking efficiency
Authors: Coelho Roberto F. , Dos Santos Walbermark M. , Martins Denizar C.
Published: July 2018

Maximum power point trackers (MPPT) are employed to maximize the photovoltaic modules output power, since it is strongly affected by changes on the incident solar radiation, surface temperature and load-type. Basically, a MPPT consists on a dc-dc converter (hardware) controlled by a tracking algorithm (software) and the combination of both, hardware and software, defines the tracking efficiency. This paper shows that even when the most accurate algorithm is employed, the maximum power point cannot be tracked, since its imposition as operating point depends on the dc- dc converter static feature and the load-type connected to its output. For validating the concept, the main dc-dc converters, i.e., Buck, Boost, Buck-Boost, Cuk, SEPIC and Zeta are analyzed considering two load-types: resistive and capacitive (regulated dc bus or battery). Simulation and experimental results are compared in order to confirm the theoretical analysis.
Inversor Buck-Boost Tri-State Integrado Trifásico para Aplicações Fotovoltaicas
Authors: De Brito Moacyr A. G. , Sampaio Leonardo P. , Alves Marcos G. , Canesin Carlos A.
Published: July 2018

Este artigo apresenta um inversor buck-boost integrado trifásico do tipo 3-estados, apropriado para operar de forma isolada e/ou conectada à rede de distribuição em CA, considerando-se uma aplicação fotovoltaica. A utilização dos 3-estados, aliada à modulação por vetores espaciais, permite ao sistema apresentar um importante grau de liberdade para o projeto e desempenho dos controladores, uma vez que neste inversor, entrada e saída podem ser controladas de forma independente. Isto torna este inversor muito útil para aplicações fotovoltaicas, uma vez que o algoritmo de MPPT controla a razão cíclica principal D1 e a saída é controlada pela razão cíclica secundária D2. Salienta-se que a aplicação deste inversor com conexão à rede em CA, é ainda inédita na literatura. Finalmente, resultados experimentais são apresentados para confirmar a viabilidade da proposta.

Published: July 2018

Wstęp

Płeć psychologiczna jest zbiorem cech psychicznych, kulturowo przypisywanych mężczyźnie lub kobiecie. Nie ma związku z płcią biologiczną, ale wpływa na sposób przeżywania, reagowania i zachowania człowieka. Celem badania było porównanie płci psychologicznej kobiet uprawiających jogę oraz inne formy grupowej aktywności fizycznej.

Materiał i metody

Zbadano 112 dorosłych kobiet, które przynajmniej od 1 miesiąca uprawiały minimum 1 raz w tygodniu jogę (grupa A) lub inną grupową formę aktywności fizycznej (grupa B). Zastosowano Inwentarz Płci Psychologicznej (IPP) oraz Skrócony Międzynarodowy Kwestionariusz Aktywności Fizycznej (IPAQ).

Wyniki

Między grupą A i B nie wykazano różnic istotnych statystycznie w zakresie: wieku, masy ciała, BMI, czasu aktywności fizycznej w tygodniu (p > 0,05). W kwestionariuszu IPAQ średni wynik w obu grupach był wysoki (> 1500 MET), różnica między grupami nie była istotna (p > 0,05). W inwentarzu IPP najwięcej badanych z grupy A prezentowało płeć psychologiczną kobiecą (57,14%), następnie nieokreśloną płciowo (28,57%), androgeniczną (10,71%) i męską (3,57%). W grupie B najwięcej badanych miało płeć psychologiczną androgeniczną (35,71%), następnie: nieokreśloną (33,93%), męską (23,21%) i kobiecą (7,14%). Różnica między grupami była w tym zakresie istotna (p < 0,001). Nie potwierdzono zależności między wynikami inwentarza IPP i kwestionariusza IPAQ (p > 0,05).

Wnioski

Kobiety uprawiające jogę różnią się w zakresie płci psychologicznej od kobiet uprawiających inne formy aktywności fizycznej. W pierwszej grupie dominuje płeć psychologiczna żeńska, w drugiej zaś androgeniczna.

Analysis of the ash content in biomass conducted through the incineration process in the muffle furnace at a given temperature of 575+25oC. The result depends on the accuracy level on the temperature sensor in the muffle furnace. It was attempted to achieve the optimum temperature and to detect the muffle furnace temperature by installing the thermocouple sensor type K directly  the porcelain sample plate. It yielded that by direct incineration process and gradual process the setup point reached in 60-90 minutes and 150-180 minutes before attaining the steady temperature, respectively. The temperature distributed uniformly for all treatments at + 6.61 oC. The temperature measurement accuracy was + 1.18%, and the overall temperature gradient was + 28.69 oC. Moreover, there was no difference in the temperature fluctuation among the treatments at the temperature of  + 20.95 oC. The optimum temperature of the chamber was  588 oC for analyzing ash content of biomass.

Published: July 2018

O angiofibroma celular é uma entidade tumoral mesenquimatosa rara, descrita pela primeira vez em 1997, sem predomínio de género e que surge tendencialmente na quarta década de vida. A localização mais habitual na mulher é superficial a nível da região vulvovaginal, confundindo-se muitas vezes a nível vulvar com quisto/tumor da glândula de Bartholin. No entanto, estão descritos alguns casos de tumor em localização profunda e extra-pélvica. O tratamento é excisional e a recorrência é baixa. É apresentado um caso de uma paciente com uma formação heterogénea a nível da região anexial direita, cuja cirurgia mostrou tratar-se de uma formação nodular alongada, retroperitoneal, localizada a nível dos espaços paracervical e paravesical direitos, que se excisou. O estudo histológico revelou tumor mesenquimatoso compatível com angiofibroma celular.

Geometry of Chalcogenide Negative Curvature Fibers for CO2 Laser Transmission
Authors: Wei Chengli , Menyuk Curtis R. , Hu Jonathan
Published: July 2018

We study impact of geometry on leakage loss in negative curvature fibers made with As2Se3 chalcogenide and As2Se3 chalcogenide glasses for carbon dioxide (CO2) laser transmission. The minimum leakage loss decreases when the core diameter increases both for fibers with six and for fibers with eight cladding tubes. The optimum gap corresponding to the minimum loss increases when the core diameter increases for negative curvature fibers with six cladding tubes. For negative curvature fibers with eight cladding tubes, the optimum gap is always less than 20 μm when the core diameter ranges from 300 μm to 500 μm. The influence of material loss on fiber loss is also studied. When material loss exceeds 102 dB/m, it dominates the fiber leakage loss for negative curvature fiber at a wavelength of 10.6 μm.
On the Wake Properties of Segmented Trailing Edge Extensions
Authors: Gunasekaran Sidaard , Curry Daniel
Published: July 2018

Changes in the amount and the distribution of mean and turbulent quantities in the free shear layer wake of a 2D NACA 0012 airfoil and AR 4 NACA 0012 wing with passive segmented rigid trailing edge (TE) extensions was investigated at the University of Dayton Low Speed Wind Tunnel (UD-LSWT). The TE extensions were intentionally placed at zero degrees with respect to the chord line to study the effects of segmented extensions without changing the effective angle of attack. Force based experiments was used to determine the total lift coefficient variation of hte wing with seven segmented trailing edge extensions distributed across the span. The segmented trailing edge extensions had negligible effect of lift coefficient but showed measurable decrement in sectional and total drag coefficient. Investigation of turbulent quantities (obtained through Particle Image Velocimetry (PIV)) such as Reynolds stress, streamwise and transverse RMS in the wake, reveal a significant decrease in magnitude when compared to the baseline. The decrease in the magnitude of turbulent parameters was supported by the changes in coherent structures obtained through two-point correlations. Apart from the reduction in drag, the lower turbulent wake generated by the extensions has implications in reducing structural vibrations and acoustic tones.
Effect of Sharp Diameter Geometrical Modulation on the Magnetization Reversal of bi-Segmented FeNi Nanowires

Controlling functional properties of matter and combine them for engineering a functional device is nowadays a common direction of scientific community. For instance, heterogeneous magnetic nanostructures can make use of different types of geometrical and compositional modulations to achieve the control of the magnetization reversal along with the nano-entities and thus enabling the fabrication of spintronic, magnetic data storage and sensing devices, among others. In this work, diameter modulated FeNi nanowires are fabricated paying special effort to obtain sharp transition regions between two segments of different diameters (from about 450 nm to 120 nm), enabling precise control over the magnetic behavior of the sample. Micromagnetic simulations performed on single bi-segmented nanowires predict a double step magnetization reversal where the wide segment magnetization switches near 200 Oe through a vortex domain wall, while at 500 Oe the magnetization of the narrow one is reversed through a corkscrew like mechanism. Finally, these results are confirmed with magneto-optic Kerr effect measurements at the transition of isolated bi-segmented nanowires. Furthermore, macroscopic vibrating sample magnetometry is used to demonstrate that the magnetic decoupling of nanowire segments is the main phenomenon occurring over the entire fabricated nanowires.
Carbon Nanocones with Curvature Effects Close to Vertex
Authors: Cox Barry J , Hill James M
Published: July 2018

The conventional rolled-up model for carbon nanocones assumes that the cone is constructed from a rolled-up graphene sheet joined seamlessly, which predicts five distinct vertex angles. This model completely ignores any effects due to the changing curvature and all bond lengths and bond angles are assumed to be those for the planar graphene sheet. Clearly curvature effects will become more important closest to the cone vertex, and especially so for the cones with the smaller apex angles. Here we construct carbon nanocones which in the assembled cone are assumed to comprise bond lengths and bond angles which are, as far as possible, equal throughout the structure at the same distance from the conical apex. Predicted bond angles and bond lengths are shown to agree well with those obtained by relaxing the conventional rolled-up model using the LAMMPS software. The major objective here is not simply to model physically realisable carbon nanocones for which numerical procedures are far superior, but rather to produce an improved model that takes into account curvature effects close to the vertex, and from which we may determine an analytical formula which represents an improvement on that for the conventional rolled-up model.
Sustainability Awareness and Principle-Based Jurisprudence:  A Study on the Developed and Developing Nations from 1974 to 2019
Authors: Li Rita Yi Man
Published: July 2018

According to Maslow theory, we satisfy the basic needs before the other goals. We speculate that sustainability or sustainable development is mainly concerned by the developed nations. We review this by a) studying 125790 sustainability articles published from 1974 to 2018 and 104599 sustainable development articles in Web of Science from 1981 to 2018, b) 77382 sustainability articles published from 1982 to 2019 and 130334 “sustainable development” published between 1981 and 2019 in Scopus, and c) number of Google search 2004 to 2018. The results show that Australia, Zimbari and Uganda ranked top three in number of searches for sustainability in Google. All the top five cities with the largest number of sustainability searches in Google come from Africa. Regarding academic publications, China, India and Brazil record top ten largest number of sustainability/sustainable development articles in Scopus. China records the largest number of sustainable development articles in Web of Science and second in Scopus. Six out of the ten top most productive institutions that publish sustainable development articles indexed in Scopus come from developing countries, indicating that developing countries are aware of sustainability issue. We then hypothesize that high degree of separation between environmental laws and moral as reflected in jurisprudence in less developed nations lead to non-compliance by throwing light on the three case studies.
Quantum Rayleigh Annihilation of Entangled Photons
Authors: Vatarescu Andre
Published: July 2018

The interpretation of published experimental results intended to prove the existence of a quantum phenomenon of non-locality involving photonic entangled states did not take into consideration the existence of the quantum Rayleigh conversion of photons in dielectric media. This phenomenon leads to the existence of high levels of correlations between two independent photonic and linearly polarized quantum states generated after the entangled photons have been absorbed through the quantum Rayleigh conversion. Both pure and mixed individual states of polarization result in expressions normally associated with entangled photonic states, providing support for the view that the physical reality of quantum non-locality is highly questionable.
“Not as the Gentiles”: Sexual Issues at the Interface between Judaism and its Greco-Roman World
Authors: Loader William
Published: July 2018

Sexual Issues played a significant role in Judaism’s engagement with its Greco-Roman world. This paper will examine that engagement in the Hellenistic Greco-Roman era to the end of the first century CE. In part sexual issues were a key element of demarcation between Jews and the wider community, alongside such matters as circumcision, food laws, sabbath keeping and idolatry. Jewish writers, such as Philo of Alexandria, make much of the alleged sexual profligacy of their Gentile contemporaries, not least in association with wild drunken parties, same-sex relations and pederasty. Jews, including the emerging Christian movement, claimed the moral high ground. In part, however, matters of sexuality were also areas where intercultural influence is evident, such as in the shift in Jewish tradition from polygyny to monogyny, but also in the way Jewish and Christian writers adapted the suspicion and sometimes rejection of passions characteristic of some popular philosophies of their day, seeing them as allies in their moral crusade.
