Fazenda Santo Antônio do Paiol, Valença/RJ: pioneirismo em serviços de hospitalidade
Authors: D'Onofre Dan Gabriel 
Published: May 2020

Localizada no município fluminense de Valença, a Fazenda Santo Antônio do Paiol teve sua fundação ligada ao Ciclo do Café. Durante o século XIX, a égide do desenvolvimento baseado no modelo plantation, tendo o café (Coffea sp.) como principal gênero vegetal de produção, foi a batuta para a condução da ocupação do território, a resultar impactos de diversas ordens. Durante o período de maior acumulação monetária da cafeicultura imperial, suntuosos palácios, casarões e sedes de fazendas foram erguidos por todo Vale do Paraíba fluminense. Ainda assim, em meio a esse conjunto de fazendas que se espalharam a ferro, fogo, sangue e suor, cada uma delas possui particularidades que ainda são desconhecidas para fora do discurso turístico. Nesse sentido, o presente trabalho se dedica a discorrer sobre o processo de abertura de visitação da Fazenda Santo Antônio do Paiol, liderada por Dona Francisca Olympia Alves de Queiroz Esteves, ainda na década de 1960. Para tanto, através de uma abordagem qualitativa, a pesquisa foi conduzida tendo como instrumentos a coleta de imagens por fotografias, bem como a aplicação de formulários junto aos anfitriões atuais. Para além da observação participante, posto que o pesquisador esteve a conviver com os entrevistados, bem como a consumir os serviços de hospitalidade ofertados junto à Fazenda Santo Antônio do Paiol, os dados coletados em diário de campo, somado aos demais obtidos pelos instrumentos supracitados, foram analisados por triangulação. Vale destacar que, o artigo também se consolidou através de uma pesquisa histórica, com base nos dados secundários advindos da produção da área da história, da arquitetura e da economia. Por fim, destaca-se que, de modo inusitado, a Fazenda Santo Antônio do Paiol é uma das pioneiras na oferta de hospitalidade comercial em pleno início da segunda metade do século XX, no sul do Estado do Rio de Janeiro.

Background and objectives
Studies of adults have demonstrated an association between metabolic acidosis, as measured by low serum bicarbonate levels, and CKD progression. We evaluated this relationship in children using data from the Chronic Kidney Disease in Children study.

Design, setting, participants, & measurements
The relationship between serum bicarbonate and a composite end point, defined as 50% decline in eGFR or KRT, was described using parametric and semiparametric survival methods. Analyses were stratified by underlying nonglomerular and glomerular diagnoses, and adjusted for demographic characteristics, eGFR, proteinuria, anemia, phosphate, hypertension, and alkali therapy.

Results
Six hundred and three participants with nonglomerular disease contributed 2673 person-years of follow-up, and 255 with a glomerular diagnosis contributed 808 person-years of follow-up. At baseline, 39% (237 of 603) of participants with nonglomerular disease had a bicarbonate level of ≤22 meq/L and 36% (85 of 237) of those participants reported alkali therapy treatment. In participants with glomerular disease, 31% (79 of 255) had a bicarbonate of ≤22 meq/L, 18% (14 of 79) of those participants reported alkali therapy treatment. In adjusted longitudinal analyses, compared with participants with a bicarbonate level >22 meq/L, hazard ratios associated with a bicarbonate level of <18 meq/L and 19–22 meq/L were 1.28 [95% confidence interval (95% CI), 0.84 to 1.94] and 0.91 (95% CI, 0.65 to 1.26), respectively, in children with nonglomerular disease. In children with glomerular disease, adjusted hazard ratios associated with bicarbonate level ≤18 meq/L and bicarbonate 19–22 meq/L were 2.16 (95% CI, 1.05 to 4.44) and 1.74 (95% CI, 1.07 to 2.85), respectively. Resolution of low bicarbonate was associated with a lower risk of CKD progression compared with persistently low bicarbonate (≤22 meq/L).

Conclusions
In children with glomerular disease, low bicarbonate was linked to a higher risk of CKD progression. Resolution of low bicarbonate was associated with a lower risk of CKD progression. Fewer than one half of all children with low bicarbonate reported treatment with alkali therapy. Long-term studies of alkali therapy’s effect in patients with pediatric CKD are needed.

Este documento describe el modelamiento de un convertidor AC-DC y el diseño de una técnica de Control Proporcional Integral Generalizado (GPI). El diseño de dicha técnica se da en el contexto del rechazo activo de perturbaciones (ADRC), en el cual se muestra que las técnicas de control GPI son capaces de rechazar las perturbaciones de carácter endógeno y exógeno de la planta, lo que lleva a un error de seguimiento acotado y dicha cota puede hacerse tan pequeña como se quiera al alejar las raíces del eje imaginario.
La responsabilidad social empresarial prescinde de los beneficios tributarios Colombianos
Authors: Lemus-Quintero Jennifer Andrea , Carrascal-Delgado Fabián Alfredo 
Published: May 2020

El siguiente artículo tiene como objetivo enfatizar el concepto de Responsabilidad Social Empresarial, desde fundamentos como la responsabilidad, la ética y el desarrollo sostenible, y demostrar la incoherente relación que ha establecido el contribuyente del impuesto sobre la renta, de naturaleza jurídica, entre sus prácticas y los beneficios tributarios en Colombia. Ningún beneficio tributario tiene incidencia en la adopción y aplicación de la responsabilidad social empresarial, el solo hecho de estar reglamentado la contradice totalmente en su naturaleza. Establecer relaciones entre la responsabilidad social empresarial y beneficios tributarios hace que la empresa permanezca detrás de beneficios en su carga tributaria siendo cada vez más propensos a crear una dependencia económica, social y ambiental insostenible. La revisión del tema es de tipo cualitativo y descriptivo, el método utilizado es el deductivo.

Published: May 2020

Six new Pd(Il) and Ni(Il) metal complexes of N, O-bidentate (LI, L2) and ONNO-tetradentate (L3) Schiff base ligands have been synthesized. The compounds were characterized via various physicochemical and spectroscopic techniques namely elemental analysis (CHN), FT-IR, 1H and 13C NMR. as well as magnetic susceptibility measurement. All complexes showed diamagnetism indicating that they are square planar complexes. Catalytic performance of Pd(Ll)2 and Pd(L2)2 were investigated/or Heck cross-coupling reaction under optimum operating parameters, monitored using GC-FID for 6 h of reaction time in inert conditions. High catalytic activities of up to 90% were observed in the presence of triethylamine as base and DMA as solvent at J0()"C with I mmol% catalyst loading. The mechanism of catalyzed Heck reaction is proposed to go through a series of conversion of Pd(0)/Pd(Il).

The commercial robots are expensive for use in the educational institutions. The operation of them will not leave room for experimentation, which is necessary in an educational institution. Further a large number of components that can be used for building a robot are readily available in the market. Hence this project has been taken up to allow us to build a working robot using as many of the off the shelf components to provide the necessary flexibility. This would make it a low cost robot with enough flexibility for the students to experiment the various functions of the robot.The mechanical component of the manipulator was built with three degrees of freedom, one revolute and two prismatic joints. This configuration is most common to be used as a material-handling device for machine tools. The revolute joint was achieved by making use of a pneumatic rotary table and one prismatic joint is realized by means of a pneumatic cylinder. The second prismatic joint in the Z-direction is achieved by the use of an AC servomotor with a ball screw and linear motion elements to provide for accurate positioning capability. The gripper had been designed for cylindrical components, since this robot was conceived as a material handling unit for a CNC turning center. All the necessary design calculations had been done and the finite element analysis was carried out for the main structure. The control system of the robot was one of the crucial elements. A PC is used as a controller. The motion control was carried out with the help of a motion control card DC2-PC100. It had the ability to control 2 servo and 2 stepper motors in addition to other digital and analogue controls. Several types of sensors and actuators were used for the robot to be fully automatic. The signal conditioning circuitry was designed in house for the interfacing between sensors, actuators and controllers. The control algorithm was developed with the necessary functioning to coordinate all the joint movement as well as gripper manipulation.

Penelitian ini membahas perbedaan struktur dan makna pada penggunaan verba bersinonim suru dan yaru dalam bahasa Jepang. Metode yang digunakan dalam penelitian ini adalah metode deskriptif dan juga mencoba mennyulih verba suru dan yaru dalam berbagai macam jenis kalimat untuk mengetahui perbedaan dan persamaannya baik secara struktur maupun semantis. Hasil analisis menunjukkan bahwa terlepas dari kebersinoniman kedua verba ini dalam makna’ melakukan sebuah perbuatan’, penulis menemukan beberapa ciri khas struktur dari masing – masing verba pada saat mengisi posisi predikat sebuah kalimat yang sama. Selain itu, penulis juga menemukan makna verba yaru yang tidak ditemukan pada kamus-kamus referensi yang ada yaitu ‘mengirimkan seseorang untuk melakukan sesuatu’ yang tidak ditemukan pada penggunaan verba suru. Terlepas dari kebersinoniman kedua verba, hasil peneltian ini menunjukkan bahwa baik verba suru maupun yaru memiliki kekhasan secara struktur dan makna sehingga meskipun bersinonim bukan berarti kedua verba tersebut selalu dapat saling menyulih.

Authors: Przeniosło-Siwczyńska Monika , Grelik Aleksandra , Kwiatek Krzysztof 
Published: May 2020

Abstract

Introduction
The authorisation of tylosin as feed additive was withdrawn for reasons of human health concerning resistance of pathogenic bacteria. An analytical method for the identification and quantification of tylosin in animal feed was developed and validated.

Material and Methods
The samples were extracted using an acidified methanol:water mixture and solid-phase extraction was employed for the isolation of the antibiotic from diluted feed samples. Tylosin was analysed by liquid chromatography with electrospray ionisation mass spectrometric detection. The method’s performance was evaluated in adherence to the Commission Decision 2002/657/EC.

Results
The recovery of the analyte from spiked samples was determined to be in the range from 78.9% to 108.3% depending on tylosin concentrations. The CCα and CCβ values for tylosin in feeds were determined at 0.085 mg kg-1 and 0.091 mg kg-1, respectively. The method detection limit was found to be 0.035 mg kg-1 and the quantification limit 0.05 mg kg-1. The applicability of the developed method was tested by analysing real feed samples.

Conclusion
A reliable LC-MS method was developed to identify and quantify tylosin in animal feed with a good repeatability and a high specificity and sensitivity. Because of these characteristics, the proposed method is applicable and could be deemed necessary within the field of feed control and safety.
