Authors: Subba Deepak
Published: December 2019

Organizational identification has been identified as an important construct in behavioral research. It has been viewed from different perspectives such as marketing, organizational behavior, human resource management, and psychology. This study is conducted in organizational behavior context among the employees of tourism industry in Sikkim and gave some important contribution which can be useful to researchers and practitioners. With the application of social identity theory, the study investigated the antecedent and consequences of organizational identification. To test the research model, self-reports of 246 respondents are used and for analyzing data explorative factor analysis, confirmatory factor analysis and structural equation modeling were applied. Findings of the study suggested that perceived organizational support emerged as an antecedent of organizational identification, whereas job satisfaction and knowledge sharing behavior emerged as consequences of organizational identification.

Authors: Cengiz Hasret , Varım Ceyhun , Demirci Taner , Cetin Sedat
Published: December 2019

Background & Objective: Subacute Granulomatous Thyroiditis (De Quervain’s Thyroiditis) is an acute painful inflammatory disease of the thyroid. We aimed to investigate easily accessible and cheap hemogram based parameters of Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte Ratio (PLR), and Mean Platelet Volume (MPV) in the follow up of inflammatory thyroid disease.

Methods: Patients admitted to Sakarya University Education and Research Hospital Endocrinology and Metabolism Outpatient Clinic and diagnosed as Subacute Granulomatous Thyroiditis between May 2017 and November 2018 were included in the study. Hemogram, thyroid function tests and acute phase values ​​of these patients were recorded and compared with the values ​​after treatment and disease recovery. On the sixth month, thyroid function tests were repeated and the rate of permanent hypothyroidism was screened. The relationships between initial hemogram parameters and acute phase reactants were evaluated.

Results: Total 71 patients were included in our study. 60 (84.5%) were female and 11 (15.5%) were male. The F/M ratio was found to be 6/1. Mean age was 43 ± 9.95 years. Receiver Operating Characteristics (ROC) Curve Analysis was performed and values for Area Under the Curve (AUC) for NLR and PLR, respectively, were 0.739 (95% CI 0.657-0.820 p<0.0001) and 0.772 (95% CI 0.694-0.850 p<0.0001), which are significant and associated with disease activity. However, the AUC for MPV parameter was: 0.578 (95% CI 0.484-0.672 P: 0.10) and was not significant. The cut off values defined as 2.4 (80% sensitivity and 51% specificity) for NLR and 146.84 (83% sensitivity and 54% specificity) for PLR for the acute phase of the disease. In the Correlation Analysis, NLR and PLR values ​​were significantly correlated with ESR and CRP parameters, which are the most commonly used acute phase reactants.

Conclusion: According to the present study, we believe that the NLR and PLR parameters will be of benefit in the follow-up the disease, accurately demonstrate the inflammatory load in the acute phase of the disease, and correlate with the common acute phase reactants.

Authors: Arif Sunila Tashfeen , Mahmood Rafia , Khan Saleem Ahmed , Khadim Tahir
Published: December 2019

Objective: To determine the frequency of additional chromosomal abnormalities in Philadelphia chromosome positive Chronic Myeloid Leukemia (CML) by conventional cytogenetic analysis.

Methods: This descriptive cross sectional study was conducted at Armed Forces Institute of Pathology (AFIP), Rawalpindi, from January 2012 to December 2016. A total number of 528 newly diagnosed CML patients were included in the study. The subjects were tested for the presence of Philadelphia (Ph) chromosome and other additional cytogenetic abnormalities by conventional cytogenetic analysis interpreted according to International System of Human Cytogenetic Nomenclature (ISCN) criteria. Molecular analysis for BCR-ABL was also performed for each patient. The additional cytogenetic abnormalities were then classified into major route abnormalities and minor route abnormalities.

Results: Out of the 528 newly diagnosed CML patients, 378 (71.6%) were males and 150 (28.4%) were females. The age of patients ranged between 18 to 74 years. Four hundred and ninety-eight (94.3%) patients showed Philadelphia chromosome on karyotyping while 30 (5.7%) were negative for the Philadelphia chromosome. On analysis of these 498 Philadelphia positive patients, additional cytogenetic aberrations were detected in 26 (4.9%) patients. Of these, 7 (1.3%) had major route abnormalities while 19 (3.6%) had minor route abnormalities.

Conclusion: The frequency of additional chromosomal abnormalities in our study were not in accordance with previous local and international studies.

Uniportal VATS technique for primary spontaneous pneumothorax: An analysis of 46 cases
Authors: Kapicibasi Hasan Oğuz
Published: December 2019

Objective: In the treatment of primary spontaneous pneumothorax (PSP), the influence of safety and applicability of uniportal video assisted thoracoscopic surgery (VATS) bullectomy/blebectomy and pleurectomy method were evaluated in 46 patients.

Methods: Between November 2010 and January 2019, 46 patients (36 males, 10 females; mean age 24.2 years; range 16-36 years) undergoing uniportal video thoracoscopic bullectomy/blebectomy and apical pleurectomy for primary spontaneous pneumothorax were evaluated retrospectively at Canakkale Onsekiz Mart University (COMU). One patient underwent surgery for the second time after three months for contralateral pneumothorax and counted as two different patients, hence forty seven operations were performed in total. The cases were evaluated in terms of age, gender, comorbidity, duration of hospital stay, histopathological diagnosis, postoperative morbidity and mortality.

Results: Right surgical intervention was performed in 20 cases (42.6%) and left surgical intervention in 27 cases (57.6%). A total of 15 (31.9%) surgical operations were performed during the first attack, 30 (63.8%) during the second attack and 2 (4.3%) during third and more attacks. There was prolonged air leakage in all patients operated during the first episode. All cases underwent wedge resection and pleurectomy with endoscopic stapes. None of the patients required thoracotomy. Postoperative drainage period was between 2-7 days (mean: 4.1) and the duration of hospitalization was between three to eight days. Postoperative pain and paraesthesia were observed in eight cases. Prolonged air leakage was observed in five cases.

Conclusion: With video thoracoscopic uniportal technique, not only lung biopsy and resection but also bullectomy/blebectomy and pleurectomy operations can be performed safely in the treatment of PSP. In view of this information, minimally invasive techniques are seen as more advantageous than conventional techniques.

DNA methylation changes in biomarker loci occur early in cancer progression
Authors: Vrba Lukas , Futscher Bernard W.
Published: December 2019

Tumor-specific DNA methylation can be used for cancer diagnostics and monitoring.  We have recently reported a set of DNA methylation biomarkers that can distinguish plasma samples from lung cancer patients versus healthy controls with high sensitivity and specificity.  Furthermore, the DNA methylation signal from the biomarker loci detected in plasma samples correlated with tumor size and decreased after surgical resection of lung tumors.  In order to determine the timing of DNA methylation of these loci during carcinogenesis and thus the potential of the biomarkers to detect early stages of the disease we analyzed the DNA methylation of the biomarker loci in five precancerous conditions using available data from the GEO database.  We found that the DNA methylation of the biomarker loci is gained early in carcinogenesis since most of the precancerous conditions already have biomarker loci hypermethylated.  Moreover, these DNA methylation biomarkers are able to distinguish between precancerous lesions with malignant potential and those that stay benign where data is available.  Taken together, the biomarkers have the potential to detect the earliest cancer stages; the only limitation to detection of cancer from plasma samples or other liquid biopsies is the timing when tumors start to shed enough DNA into body fluids.

ESTADO LAICO E NÃO SECULARIZADO NO BRASIL: UMA REFLEXÃO À LUZ DA HISTÓRIA DO PROTESTANTISMO
Authors: Cury Marinho Mathias João Felippe
Published: December 2019

A crescente presença da religião na esfera pública e na política no Brasil traz à tona desafios e tensões num Estado ao mesmo tempo formalmente laico e uma sociedade plural, mas que dá muito valor às questões religiosas. O segmento evangélico/protestante desperta natural interesse de pesquisa devido ao crescimento expressivo e de onde emerge a Frente Parlamentar Evangélica, que defende uma pauta conservadora de costumes que, muitas vezes, parece traduzir um discurso anti-laicidade. Este trabalho, à luz de uma reflexão histórica, recupera a importância dos protestantes na concepção do Estado Laico. Ao mesmo tempo busca separar em termos analíticos os conceitos de laicidade e secularização. O trabalho conclui que não há uma guinada anti-laicidade por parte dos evangélicos, mas sim, em caráter reativo, um movimento anti-secularização, bem diferente da imagem construída pelos protestantes ao longo da história em favor da laicidade.

Published: December 2019

Resumo: Nosso artigo se propõe a desenvolver uma análise de imagens e depoimentos de praticantes de Yoga do sexo feminino, no contexto histórico dos anos setenta do século XX, quando esta era uma forma de espiritualidade considerada “alternativa”. Nossa questão central é: será que existe uma relação entre a prática de origem indiana, disseminada entre mulheres brasileiras dos anos setenta, e algum tipo de transformação social para suas praticantes? Para responder esta questão, faremos algumas considerações introdutórias sobre a história do Yoga no Brasil, seguida por uma análise das transformações das representações femininas em imagens fotográficas de publicações dos anos sessenta e setenta, e por fim analisaremos alguns depoimentos de praticantes que relacionam o Yoga a questões de gênero no período.

Potential Water Conservation Using Site-Specific Variable Rate Irrigation
Authors: Stone Kenneth C , Bauer Philip J , Sigua Gilbert C
Published: December 2019

Abstract. Site-specific variable-rate irrigation (VRI) systems can be used to spatially manage irrigation within sub-field-sized zones and optimize spatial water use efficiency. The goal of the research is to provide farmers and consultants a tool to evaluate the potential benefits of implementing VRI. The specific objective of this research is to evaluate the potential water savings using VRI management compared with uniform irrigation management to maintain soil water holding capacity above 50% depletion using two irrigation scenarios: 1) a standard 12.5 mm irrigation per application; and 2) an application to refill the soil profile to field capacity. A 21-year simulation study was carried out on a selected field with varying degrees of soil and topographic variability. The simulated field had 12 soil mapping units with water holding capacities in the top 0.30-m ranging from 42 to 70 mm. The 21-year simulation covering all weather conditions for each soil produced only two significantly different irrigation management zones for scenario 1, and for scenario 2 only one management zone. However, when the 21-year period was divided into periods with different ratios of rainfall to reference evapotranspiration, the simulations identified 1 to 5 management zones with significantly different irrigation requirements. These results indicate that variable rate irrigation system design and management should not be solely based on long term average weather conditions. Years with differing weather conditions should be used for potentially identifying management zones for VRI systems. Irrigation application depths between management zones ranged from 17 to 38 mm. However, when the actual soil areas of the study field were utilized to calculate the total volume of irrigation water applied, it resulted in an increase in water usage in the 2 and 4 management zones ranging from -1.2% to 5.8%. Water usage with VRI over uniform irrigation was greater by -1.6% to 6.8% in the 12.5 mm irrigations and by -1.2% to 2.2% for the field capacity irrigations Keywords: Management zones, Precision farming, Variable-rate irrigation, Water conservation.
Kansas Center Pivot Uniformity Evaluation Overview
Authors: Rogers Danny H , Aguilar Jonathan , Sharda Vaishali
Published: December 2019

Abstract. Center pivot irrigation systems are the most common system type in Kansas for a variety of factors – one of which is the ability to deliver a uniform depth of water application for a variety of crops and field conditions. Uniform applications are dependent on properly designed, installed and operated sprinkler nozzle packages. Uniformity evaluations were conducted as part of the Mobile Irrigation Lab (MIL) project to promote adoption of improved irrigation management practices with an emphasis on ET based irrigation scheduling. Since efficient and uniform water applications are critical to successful irrigation scheduling; MIL assessment included evaluation of sprinkler package performance using a single line catch can test. Catch can data was used to calculate the coefficient of uniformity (CU) and average application depth. The average CU value of the tested systems was 78.7 with a range of from 91.9 to 53.2. Many of the factors affecting pivot uniformity could have been identified and corrected with a visual inspection and/or comparison to the manufacturer’s sprinkler design specifications. Some of the catch tests indicated poorly designed and/or maintained sprinkler systems with reduced uniformity directly impacting crop performance, water use efficiency and economic results. Initial information was used in extension programs to illustrate the effect of various correctable sprinkler package deficiencies on performance and to encourage irrigation farmers to examine their nozzle packages and operating conditions. Keywords: Center pivot irrigation, Sprinkler packages, Uniformity.

insert between crossed linear polarizers, the fabricated device is
used to alter the intensity profile of an incident zero-order Bessel
beam. Radially polarized output beams have an intensity profile with a
pronounced singularity at the center. Beams may be rotated by a simple
reorientation of the crossed polarizers. Experimental results with our
radial polarizer correspond to a transformation of the Bessel beam

The relative power levels of two individual lasers are adjusted under a counter-propagating configuration so that the system exhibits Autler–Townes splitting (ATS). However, the ATS, which is otherwise difficult to detect in a room-temperature alkali vapor cell offering large Doppler background, is well resolved here by using a combination of modulation transfer and phase-sensitive detection techniques. The results show that the AT components clearly indicate the hyperfine structure of

Image correlation by one-dimensional signatures invariant to rotation, position, and scale using the radial Hilbert transform optimized
Authors: Castro-Valdez Alfredo , Álvarez-Borrego Josué , Solorza-Calderón Selene
Published: December 2019

This paper presents a new methodology for pattern recognition invariant to rotation, position, and scale. The method uses the correlation of signatures, where the signatures were created with a new equation called the radial Hilbert transform optimized (RHTO) for longer signatures. An analysis with eight non-homogeneous illumination patterns was performed with 2000 letter variants and 30 phytoplankton species. The higher confidence level was founded using the radial Hilbert optimized methodology. Also, it utilized a correlation called adaptive linear–nonlinear correlation, which gave a better discrimination performance than the nonlinear correlation function.
Hierarchical and reconfigurable optical/electrical interconnection network for high-performance computing
Authors: Zhao Zuoqing , Guo Bingli , Shang Yu , Huang Shanguo
Published: December 2019

Compared with electrical packet switches, optical switching technology could enable a more desirable high-performance computing (HPC) system with lower power consumption, lower delay, higher bandwidth, and more flexibility. In this article, we designed a hierarchical and reconfigurable optical/electrical HPC interconnection network. The traffic matrix of the target task can be decomposed into multiple matrix groups that are executed in parallel, and the network topology in each layer can be reconfigured according to the subtraffic matrix associated with this layer. For interlayer cross-connection, we use a shuffle network to offer a direct optical bypass for a huge aggregated amount of interlayer communication requirements, as well as multiple light paths. We propose a reconfiguration optimization algorithm and routing algorithm to optimize network performance. Simulation results show that, with the proposed architecture and algorithms, the average path length per unit of communication intensity is minimized by 13.7%–52.4%, the delay is reduced by more than 14.8%, and throughput is improved by 33% at least compared with Mesh, Torus, and Dragonfly.
CIE self-luminous gray-scale calculation: inflections, parameters, and high-contrast limiting behavior
Authors: Carter Robert
Published: December 2019

Wide generalizability of the CIE-recommended gray-scale calculation for self-luminous devices suggests that its parameters, the extrema of the calculation’s derivatives, and its limiting behavior are fundamental. The calculation has a negative-contrast point of inflection that is not predicted by any other gray-scale calculation, but that is consistent with data and with the terrestrial luminance histogram. The parameters of the calculation are analyzed, and their significance is explained. High-positive-contrast behavior of the calculation is shown and related to scientific literature. This knowledge represents a clearer understanding of daylight suprathreshold vision, and it enables optimal luminance-coding of contemporary high-resolution, high-contrast, high-luminance displays.

This study introduces design and coupling techniques, which bridge an opaque liquid metal, optical WGM mode, and mechanical mode into an opto-mechano-fluidic microbubble resonator (MBR) consisting of a dielectric silica shell and liquid metal core. Benefiting from the conductivity of the liquid metal, Ohmic heating was carried out for the MBR by applying current to the liquid metal to change the temperature of the MBR by more than 300 °C. The optical mode was thermally tuned (>3 nm) over a full free spectral range because the Ohmic heating changed the refractive index of the silica and dimeter of the MBR. The mechanical mode was thermally tuned with a relative tuning range of 9% because the Ohmic heating changed the velocity and density of the liquid metal.

Published: December 2019

The main advantage of an integral imaging system is that it does not cause a vergence-accommodation conflict to the viewer, as happens in other types of three-dimensional (3D) display systems. However, it still has the disadvantage of having a limited depth range. In this Letter, the fabrication of the electrowetting liquid lens array with an adjustable focal length is presented. With the liquid microlens array, we propose a focus tunable integral imaging system having an enhanced expressible depth range. The fabricated lens array has 1 mm lens pitch, 100 µm sidewall,

Published: December 2019

We report, to the best of our knowledge, the first Raman sensor for broadband vapor-phase volatile organic compounds (VOCs) based on silicon nitride waveguides functionalized with a mesoporous silica top-cladding. The Raman response of low-concentration VOC gases is evanescently probed via a centimeter-long functionalized slot waveguide. Thanks to the four-orders-of-magnitude concentration factor offered by the mesoporous coating, the detection limit of acetone, ethanol, and isopropyl alcohol (IPA) is determined to be 594, 157, and 53 ppm, respectively, with 1 s measurement time in the current setup. Capable of multiplex gas sensing in a complex matrix through fast and reversible adsorption, the demonstration paves the way to on-site continuous VOC monitoring.

We experimentally demonstrate a high-spectral-purity photon source by designing a dual-Mach–Zehnder-interferometer-coupled silicon ring resonator, wherein the linewidths of pump and signal (idler) resonances can be engineered independently. A high spectral purity of

correlation measurement, which exceeds the theoretical 93% bound of a traditional ring’s spontaneous four-wave-mixing photon source. This source also possesses high performance in other metrics including a measured coincidence of 9599 pairs/s and a preparation heralding efficiency of 52.4% at a relatively low pump power of 61 µW as well as high drop-to-through suppression of 20.2 dB. By overcoming the trade-off between spectral purity and brightness in the post-filtering way, such a method guarantees bright pure photons and will pave the way for development of on-chip quantum information processing with improved operation fidelity and efficiency.
Polarization-independent plasmonic absorption in stacked anisotropic 2D material nanostructures
Authors: Xia Sheng-Xuan , Zhai Xiang , Wang Ling-Ling , Wen Shuang-Chun
Published: December 2019

Here we study the possibility to achieve polarization-independent optical absorption in stacked anisotropic 2D material nanostructures (NSs). Focusing on black phosphorus, we demonstrate that by crossly stacking even-layered NSs, surface plasmons resonant in the two lattice directions are complementary excited, leading to polarization-independent absorption at any layer distance. This property is numerically validated using full electromagnetic simulations and theoretically predicted by a two-particle model. Our proposal can open up the possibility of anisotropic 2D materials to develop polarization-independent plasmon devices such as sensors and absorbers.

Published: December 2019

The InAs1−xSbx ternary alloy band gap nonlinearly depends on the composition, which provides the opportunity for use of this material in devices operating in a wide range of infrared radiation. We present experimental results for InAs1−xSbx samples for Sb composition from 0.1 to 0.8. The most common way to determine it is by using a high resolution X-ray diffractometer. In a previous article, we showed that energies of folded longitudinal acoustic and folded transverse acoustic Raman peaks are linearly correlated with mole fraction. In this work, we will illustrate how to determine mole fraction using peak energy and calculate the bowing parameter for InAs1−xSbx at 300 K.
CUSTOM-MADE RHEOMETER FOR THE EXPERIMENTAL STUDY OF POLYURETHANE RESIN PU9010
Authors: Fissore Luciano , Diebels Stefan
Published: December 2019

Polyurethane resins are well-known examples in aerospace industry, electronics and automotive as an adhesive or coating because of their broad spectrum of properties. They are obtained by a process called curing, where in the initial uncured state the mixture of monomers exhibits a viscous behavior and at the end of the polymerization reaction, a solid with viscoelastic properties is formed. The shrinkage due to cross-linking and thermal expansion cause the generation of residual stresses which often result in broken adhesive layers. Therefore, the reduction of such problems is of utmost importance. In this study, a rheometer capable to conduct oscillatory-strain-controlled experiments was built in order to apply large deformations not only to the sample at the beginning of the reaction but also during the curing process and to the fully cured adhesive.

The work illustrates how building parameters of the Additive Manufacturing process Fused Filament Fabrication can aﬀect not only the mechanical properties but also the surface wettability and morphology. Wettability and morphology are relevant factors in bonded joints performance. Advantages of polymeric additive manufacturing are to allow a re-design of components with locally controlled properties and integrated functions. Major limitations are related to the lack of material testing standardization and constraints due to the build volume and to the object orientation for printability: the latter problem scan be addressed with the use of bonded joints that allow to create bigger assemblies from smaller parts optimally designed to take advantage of material orthotropy and without the structural drawbacks. In this study, two materials are considered, acrylonitrile butadiene styrene and polylactideacid. Wettability, surface morphology and mechanical strength have been determined at diﬀerent combinations of nozzle temperature, print speed and layer thickness.

Desenho rococó nos manuscritos do Brasil do século XVIII: caminhos e expressões
Authors: Silva de Souza Antonio Wilson
Published: December 2019

Este artigo aborda origens, características e difusão do rococó, destacando, de modo especial, a ornamentação dos manuscritos do Brasil no século XVIII. Apesar dos estudos realizados sobre o estilo, as peculiaridades do desenvolvimento do rococó merecem uma análise sempre atualizada e pormenorizada, sobretudo para se entender melhor a influência que a gravura francesa exerceu sobre a criação, o desenvolvimento e a propagação do estilo na Europa e no Brasil. A ênfase na ornamentação gráfica fundamenta o exame das suas particularidades, ao possibilitar maior entendimento sobre o significado que o desenho assume como manifestação autêntica da arte, o que permite afirmar que o rococó se tornou uma singular realidade na expressão da arte brasileira.

Palavras-chave: ornato; rococó; arte brasileira.
Mistérios da canção regionalista
Authors: Dias da Costa Antonio Maurício
Published: December 2019

Este texto percorre alguns lugares na obra literária de Apollinaire que são motivados pelas errâncias urbanas do autor. Uma modernização do olhar ali se evidencia: investido de um viés alegórico e mítico, a favor de um inusitado sentimento de estranhamento do banal cotidiano, esse olhar concorre a um jogo lírico, por vezes elegíaco, que o escritor estabelece entre tempos, objetos e figuras. O errante apollinairiano concede, assim, polissêmica profundidade para o espaço e o tempo vividos, sobre fundo de uma despersonalização crescente imposta pela metrópole moderna. A adesão do poeta às formas da vida citadina revela-se, por fim, potência órfica de transfiguração lírica e mítica do presente.

Authors: Coelho Selma de Andrade , Aguiar Denise Regina da Costa
Published: December 2019

This study aimed to develop a guideline concerning the care directed toward an individual with an intestinal and/or urinary ostomy attending the Assistance Service for Ostomized Patients implemented at the Clinical Hospital of Uberlândia UFU, in order that such individuals be provided the means of self-care and thus improve their life quality. A bibliographical survey was performed on the theme, which focused on Guidelines Based on Evidence. The development of these guidelines was based on a bibliographical survey and took as its foundation the principles of Orem’s self-care theory and the educational practices applied to pedagogy in health according to Paulo Freire's philosophy concerning liberating education, qualification and dialogue between the subject and the professional, which grants the possibility of aiding the family and patient to modify their lifestyles and be the agents of transformation, thus favoring the development of their autonomy. The printed educational material brings new information and knowledge to the ostomized patient.
