ABSTRACT – In Brazil, the rainfed maize crop may undergo yield breaks due to uncertainties in the rainfall distribution. Irrigation can be a management alternative that, however, requires evaluation and planning to be helpful. The objective of this work was to analyze the simulated yield data of irrigated maize in counties of Minas Gerais state, Brazil. The CSM-CERES-Maize model was used to simulated weekly sowings of maize considering optimum agronomic conditions. A sprinkler irrigation scheme with 80% efficiency was used with automatic applications when the crop withdrew 50% of the soil available water. The harvest was scheduled to happen automatically when the crop had reached physiological maturity. The results were statistically analyzed for each county, based on goodness of fit test, ANOVA, Tukey’s test and risk analysis (stochastic dominance). The most promising sowing period was from January 16 to March 27 for all locations, except for Janaúba, for which the best sowing window was from November 14 to January 2. The treatments of highest average simulated maize yield stochastically dominated the other treatments evaluated. The CSM-CERES-Maize model proved to be a useful tool to help making decision in irrigated maize crop systems.Keywords: Zea mays L., CSM-CERES-Maize, DSSAT, risk analysis. MODELAGEM APLICADA A DATAS DE SEMEADURA DE MILHO IRRIGADO RESUMO – No Brasil, a produção de milho de sequeiro pode sofrer quebras de rendimento devido a irregularidades na distribuição de chuvas. A irrigação pode ser uma alternativa de manejo que, todavia, requer avaliação e planejamento para ser benéfica. O objetivo deste trabalho foi analisar a produtividade simulada de milho irrigado em municípios do estado de Minas Gerais, Brasil. O modelo CSM-CERES-Maize foi utilizado para simular semeaduras semanais de milho, assumindo condições agronômicas ótimas. Considerou-se um esquema de irrigação por aspersão com 80% de eficiência, com aplicações automáticas quando a planta extraísse 50% da água disponível do solo. A colheita foi programada para acontecer automaticamente quando a cultura atingisse a maturidade fisiológica. Os resultados foram estatisticamente analisados para cada município, com base em teste de aderência, ANOVA, teste de Tukey e análise de risco (dominância estocástica). O período de semeadura mais promissor foi de 16 de janeiro a 27 de março, para todos os locais, exceto Janaúba, em que a melhor janela de semeadura foi de 14 de novembro a 2 de janeiro. Os tratamentos de maior rendimento médio simulado de milho dominaram estocasticamente os demais tratamentos avaliados. O modelo CSM-CERES-Maize demonstrou ser uma ferramenta útil para auxiliar na tomada de decisão em sistemas de produção de milho irrigado.Palavras-chave: Zea mays L., CSM-CERES-Maize, DSSAT, análise de risco.

RESUMO - A inoculação das sementes com Azospirillum spp. é uma prática que tem sido rotineiramente realizada no milho, sobretudo via formulação líquida. Todavia, as respostas relativas a outros modos de inoculação com diferentes formulações são, ainda, pouco conhecidas. Desta forma, objetivou-se com este trabalho avaliar a eficiência agronômica de doses de A. brasilense em formulação polimérica em pó, aplicada diretamente na caixa semeadora, sobre os componentes da produtividade do milho. Para tanto, foi conduzido um ensaio em blocos casualisados, com quatro repetições. Os tratamentos consistiram de uma testemunha, dose total de N, ½ dose de N; ½ dose de N + inoculação comercial padrão e ½ dose de N + quatro doses de inoculante em pó (1, 2, 4 e 8 g kg-1), aplicado na caixa semeadora. Foram avaliados os caracteres produtividade, números de fileira por espiga e de grãos por fileira, massa de mil grãos, matéria seca da parte aérea e teores de N nos grãos e na parte aérea. Nas condições testadas, a dose de 2 g kg-1 de sementes do inoculante, quando associada à adubação nitrogenada de 90 kg ha-1, apresentou superioridade no rendimento da cultura, ultrapassando, inclusive, a inoculação comercial com produto líquido.Palavras-chave: Zea mays, fixação biológica, inoculante, rendimento. MAIZE YIELD IN RESPONSE TO THE APLICATION OF Azospirillum spp. INTO THE SEED TANK ABSTRACT - Seed inoculation with Azospirillum spp. is a practice that has been routinely carried out in maize crop, especially via liquid formulation. However, responses concerning other methods of inoculation of different formulations are still poorly understood. The objective of this work was to evaluate the agronomic efficiency of the application of powder formulation of Azospirillum brasilense directly into the sowing box. For this purpose, a randomized block trial with 4 replications was carried out. The treatments tested consisted of absence of N fertilizer, the full N recommendation and a combination of the half of recommended N associated with the inoculation of four doses of A. brasilense (1, 2, 4 and 8 g kg-1) in powder formulation. The following variables were evaluated: number of kernel per row, number of row per ear, shoot dry biomass, thousand seed weight, grain N content, shoot N content and grain yield. All treatments submitted to inoculation with the powder formulation showed higher yields than the treatment in which the total dose of N was applied. However, superior results were obtained for the treatment in which ½ dose of N was associated with the powder inoculant in the proportion of 2 g kg-1 of seed.Keywords: Zea mays, biological fixation, inoculant, productivity.

ResumenLa abolición de la prostitución ha sido un objetivo y una pretensión histórica del movimiento y la teoría política feminista. Sin embargo, la propuesta de considerarla como una actividad más en el marco de las relaciones laborales se presenta ahora como una urgente innovación normativa encaminada, supuestamente, a garantizar los derechos de las mujeres prostituidas. Pero esta demanda no es ajena a la transformación que ha sufrido la prostitución como actividad, que representa en la actualidad un lucrativo mercado global con dimensiones sistémicas. El presente artículo analiza los componentes estructurales del sistema prostitucional y las implicaciones de su reglamentación en la igualdad sexual para evaluar los efectos concretos de su reglamentación en el caso alemán.Palabras clave: Prostitución, Trata de seres humanos (TSH), Políticas Públicas, Explotación Sexual, Igualdad de género, Derecho Internacional Público.Abstract: The abolition of prostitution has been an objective and a historical demand of both the feminist movement and feminist political theory. However, the proposal of consideration as any other activity in the framework of labor relations, is now portrayed as an urgent regulatory innovation aimed, supposedly, at guaranteeing the rights of prostituted women. But this claim must be interpreted in relation with the transformation of prostitution as an activity, which currently represents a lucrative global market with systemic dimensions. This article analyzes the structural components of the prostitution system and the implications of its regulation on gender equality in order to evaluate the particular effects of its regulation in the German case.KeywordsProstitution, Trafficking in Human Beings (THB), Public Policies, Sexual Exploitation, Gender Equality, Public International Law.
Dignidad humana = Human dignity
Authors: Delgado Rojas Jesús Ignacio 
Published: October 2018

Resumen: La dignidad humana es un valor central para la Cultura de la legalidad y en la mayoría de ordenamientos jurídicos goza de las máximas garantías, tanto por estar ella misma protegida contra los ataques que la pudieran menoscabar como por servir de fundamento a otros derechos fundamentales. No obstante, el abuso del término en el discurso político y su fuerte carga moral y emotiva convierten la dignidad en un concepto de imprecisos contornos. En este trabajo se recupera el tratamiento clásico kantiano de la dignidad y se ofrece una lectura contemporánea que nos ayude a afrontar problemas actuales.Palabras clave: Dignidad, Kant, autonomía, felicidad, derechos humanos.Abstract: Human dignity is a central value for Culture of legality and in most legal systems enjoys the highest guarantees, because it protected against attacks that could reduce it and also because serve as basis for other human rights. However, abuse of the term in political discourse and its strong moral and emotional load become dignity concept of vague outlines. This paper recovers Kantian classic treatment of dignity and offers a contemporary reading that will help us to deal with current problems.Keywords: Dignity, Kant, personal autonomy, happiness, human rights.
Objeción de conciencia = Conscientious Objection
Authors: Triviño Caballero Rosana 
Published: October 2018

Resumen: La objeción de conciencia constituye un recurso mediante el que se pretende resolver la tensión entre el deber jurídico y el moral. Su caracterización en el seno de las sociedades democráticas está llena de matices y de contenidos no siempre compatibles entre sí, que va desde el reconocimiento explícito de la objeción como derecho a su consideración como una excepción condicionada para el cumplimiento de la norma. En función de la correspondiente noción de partida, será posible establecer las potenciales ventajas e inconvenientes que ofrece su regulación. Estos aspectos son los ejes centrales de los debates sobre la objeción de conciencia, que en la actualidad se vincula fundamentalmente al conflicto entre deberes profesionales y convicciones personales. Palabras clave: Objeción de conciencia, deber jurídico, deber moral, deber profesional, pluralismo, regulación de la objeción.Abstract: Conscientious objection is an instrument to solve the conflict between legal and moral duties. In democratic societies, it is easy to find different features and nuances to define it which are not always compatible among them (i.e. conscientious objection as a legal right vs. objection as a conditioned exemption to the law accomplishment). Depending on the guiding notion, the potential advantages and disadvantages arisen from conscientious objection regulation can be identified. These aspects are the central points which articulate conscientious objection issues, which currently are mainly related to conflicts between professional duties and personal beliefs.Keywords: Conscientious objection, legal duty, moral duty, professional duty, pluralism, conscientious objection regulation.

A passive diffusion model of fluorescein derivatives in an in vitro human brain microvascular endothelial cell (HBMEC) monolayer
Authors: Simmons Jamelle M. , Lee Yong Woo , Achenie Luke 
Published: October 2018

Eukaryotic cells have a protective plasma membrane, which restricts the free movement of molecules from the external environment to the internal environment. This study aims to computationally model the transport of fluorescein derivatives across the monolayer of human brain microvascular endothelial cells (HBMEC). The determination of plausible effective diffusion constants (Deff) will allow models to be built that could be useful beyond in vitro experimentation. Fluorescein-5-isothiocyanate (FITC) modeling produced a Deff range of 1E-20 to 5E-20 cm2/s at a 1 µm cell monolayer thickness and a Deff constant near 5E-29 cm2/s at a 5 µm cell monolayer thickness. Both fluorescein and sodium fluorescein (NaFl) modeling at the 1 and 5 µm thicknesses did not produce simulations that closely resembled the HBMEC in vitro model. Overall, it is possible that the fluorescent intensity noted with fluorescein and NaFl may be better explained by a mechanism other than passive diffusion. Simulations of FITC diffusion produced a narrow range of Deff constants that closely matched the in vitro HBMEC fluorescent intensity.

Introduction. The investigation of the contact problems for cylindrical bodies is urgent due to the engineering contact strength analysis on shafts, cores and pipe-lines. In the present paper, a new contact problem of elastostatics on the interaction between a rigid band and an infinite two-layered cylinder, which consists of an internal continuous cylinder and an outer hollow one, with a frictionless contact between the cylinders, is studied. The outer cylindrical band of finite length is press fitted. By using a Fourier integral transformation, the problem is reduced to an integral equation with respect to the unknown contact pressure.Materials and Methods. Different combinations of linearly elastic materials of the composite cylinder are considered. Asymptotics of the symbol function of the integral equation kernel at zero and infinity is analyzed. This plays an important role for the application of the analytical solution methods. A key dimensionless geometric parameter is introduced, and a singular asymptotic technique is employed to solve the integral equation.Research Results. On the basis of the symbol function properties, a special easily factorable approximation being applicable in a wide variation range of the problem parameters is suggested. The Monte-Carlo method is used to determine the approximation parameters. The asymptotic formulas are derived both for the contact pressure, and for its integral characteristic. Calculations are made for different materials and for various relative thickness of the cylindrical layer including thin-walled layers.Discussion and Conclusions. The asymptotic solutions are effective for relatively wide bands when the contact zone length is bigger than the diameter of the composite cylinder. It is significant that the method is applicable also for those cases when the outer cylindrical layer is treated as a cylindrical shell. The asymptotic solutions can be recommended to engineers for the contact strength analysis of the elastic barrels with a flexible coating of another material.
RELIABILITY-BASED DESIGN OPTIMIZATION USING OPTIMUM SAFETY FACTORS FOR LARGE-SCALE PROBLEMS
Authors: Kharmanda Gh. , Antypas I. R. 
Published: October 2018

Introduction. Reliability-Based Design Optimization (RBDO) model reduces the structural weight in uncritical regions, does not only provide an improved design but also a higher level of confidence in the design.Materials and Methods. The classical RBDO approach can be carried out in two separate spaces: the physical space and the normalized space. Since very many repeated researches are needed in the above two spaces, the computational time for such an optimization is a big problem. An efficient method called Optimum Safety Factor (OSF) method is developed and successfully put to use in several engineering applications. Research Results. A numerical application on a large scale problem under fatigue loading shows the efficiency of the developed RBDO method relative to the Deterministic Design Optimization (DDO). The efficiency of the OSF method is also extended to multiple failure modes to control several out-put parameters, such as structural volume and damage criterion.Discussion and Conclusions. The simplified implementation framework of the OSF strategy consists of a single optimization problem to evaluate the design point, and a direct evaluation of the optimum solution considering OSF formulations. It provides designers with efficient solutions that should be economic, satisfying a required reliability level with a reduced computing time.
ULTRASONIC EFFECT ON ELECTRIC SPARK FORMING AND DEVELOPMENT IN ELECTROACOUSTIC SPRAYING

Published: October 2018

Introduction. The electroacoustic application of wear-resistance coatings is studied. The work objective is to obtain a mathematical model of the ultrasonic effect on the formation and development of an electric spark occurring in the process of the electroacoustic sputtering.Materials and Methods. The effect of ultrasonic vibrations on the processes occurring during the formation and development of a spark discharge is analyzed; the equations of continuity, energy motion and transfer, with the ultrasonic field contribution are considered. Factors affecting the thermal conductivity and electrical conductivity of strongly ionized gas are studied. Research Results. When obtaining the model, it was assumed that the heat removal from the channel is carried out by a “clear emitter”. Then, for the channel region, a self-similar solution is made: pressure, temperature and density are constant over the cross-section, and velocity is proportional to the radius. A mathematical model that describes the processes occurring in the spark channel with the ultrasonic field energy effect is obtained.Discussion and Conclusions. On the basis of the developed model, it is specified that under the ultrasonic radiation effect, the radius and temperature of the spark channel increase, and conditions of the double ionization under high ultrasonic energy are created.
