One of the major causes of cancer death is through Lung cancer. Theoverlapping of cancer cells acts as an impediment for its early detection. Identifying genetic andenvironmental factors plays a vital role in developing better techniques for its prevention. And inorder to discover the anomalies in target images, time factor is paramount. In this work, decision tree algorithm is used for prediction of lung cancer whereinthe important pattern with their corresponding weightage and score is studied. Processes such as preprocessing of images and feature extraction are done using Histogram Equalization and using neural network classifier does normal or abnormality check of the patient. If lung cancer is detected early, then it will reduce many treatment options, reduce risk of invasive surgery and increase survival rate. Therefore, an easy, cost effective and time saving method will produce promising result for detection and prediction of lung cancer.

The paper ‘GEARLESS DRIVE’ being compact and portable equipment which transmits power at right angle without any gears. Here, the L - shaped joint transmits the input power in such a way that the angular forces are produced and transmitted by the joints. The amount of friction generated is minimal compared to the power being transmitted. The material used for El-bow is made up mild steel material. The mechanism is screwed to the spindle which is driven by the gearless drive transmission connected to the drive system. The entire setup is constructed and placed on the base plate. There is no back lash during the power transmission. Therefore, the efficiency of 90% - 93% can be obtained in a gearless transmission mechanism. The Mechanical drives systems are economic when compared to electrical drives and their control and components are much simpler. These are widely used in industries ranging from aviation to heavy industry. In recent trends and advancements these types of drive has become more efficient.
Estimation of hydrophysical characteristics of the aquatic environment using satellite images in the context of incomplete information
Authors: Yakymchuk Vladyslav , Sukhanov Kostiantyn
Published: December 2019

In the method of assessing the state of individual parts of the aquatic ecosystem based on satellite images (determining the concentration of total suspended and dissolved organic matter in particular), an algorithm for calculating their concentration based on data from space scanners is used for complete information. This is achieved by creating, using cosmic data, a multidimensional linear regression model of the dependence of the characteristics of temperature, salinity, total suspended matter and dissolved organic matter on the influencing factor variables —  spectral values 7 bands of Landsat-5. To assess the characteristics of the aquatic environment from satellite images of the sea surface, when the surface of the water is sometimes covered with clouds or there is no image of a part of the studied water area with the required data, it is proposed to use an optimal interpolation (extrapolation) of the spectral brightness values of images in the water areas. The method of optimal interpolation of Kolmogorov spectral brightness of satellite images under incomplete information in the task of improving and testing methods for the remote determination of the hydrophysical characteristics of the marine environment is described. The optimal Kolmogorov interpolation method was tested for the field of the spectral values of the sea surface for the problem of estimating the hydrophysical characteristics of the aquatic environment using the example of the Sentinel-2 satellite channels, which showed for the spatial resolution of 10 and 20 m insignificant errors and a sufficiently high correlation with the brightness values, and for the channels with the spatial discrimination of 60 m is smaller than the value of the correlation coefficient, which is associated with significantly larger distances between the pixels. These results are acceptable for practical use of interpolation (extrapolation) of spectral brightness values of satellite images of the sea surface under incomplete information, which creates prerequisites for creating a multidimensional linear regression model for calculating the hydrophysical characteristics of the aquatic environment according to incomplete information satellite conditions.

Published: December 2019

A destilação é provavelmente um dos processos de separação mais aplicados na indústria química, sendo que a separação das espécies se deve à diferença de volatilidade. Para abordagens práticas no ensino de engenharias, professores têm buscado desenvolver novas metodologias de ensino. Um algoritmo para a determinação do ponto de orvalho de uma mistura binária foi proposto, sendo aplicado a uma análise numérica do método gráfico de McCabe-Thiele para determinação do número de estágios teóricos e o estágio ótimo de alimentação. Os diagramas de equilíbrio líquido-vapor foram desenvolvidos com base na lei de Raoult modificada, junto com a equação de Antoine para a determinação das pressões de vapor das espécies. Já para a predição do coeficiente de atividade, foi utilizada a equação de Wilson. A partir dos algoritmos montados, foi desenvolvido uma ferramenta didática para simulação de colunas de destilação. Os resultados obtidos para o diagrama ELV de misturas binárias pelo algoritmo implementado foram comparados com os do ChemSep, sendo verificado pouco desvio entre os dados analisados. Foi feito um estudo de caso para uma coluna dedestilação que separa uma mistura binária a fim de avaliar se o algoritmo implementado para determinação do número de estágios teóricos e o estágio ótimo de alimentação é satisfatório.

The implication of a long malnutrition in baduta called stunting, the impact will experience growth barriers / height according to age and brain development so that there is a chance of losing the next generation (lost generation). This condition is likely to occur given the data from the Health Office, Banjar District is one of the largest contributors to short cases in South Kalimantan, and the largest case is found in the working area of Sungai alang puskesmas as much as 41.7% (2015) and Rahayu and Putri's research results in Sungai alang found that the majority of children under five experienced stunting of 62.7% or a total of 79 people. Ironically, this region is located on a riverbank, so the area should not be included in the category of areas with very poor public health problems with a stunting prevalence of ≥ 40%, because the local commodity produced ie the largest fish in South Kalimantan is 12,595.9 tons per year. Fish is one source of protein which is at the same time a macro nutrient that contributes energy to the body. Considering that the Alang River region is one of the areas located along the riverbanks and most of the residents' livelihoods are fish farmers, it is therefore necessary to educate these farmers so that the fish obtained are not only sold but utilized by processing fish food by modifying variants based on the menu local fish. One of the methods used so that the knowledge and skills of modifying local fish menus to farmers is effective, so the active learning method using the FTAD (Farmers Team Achievement Division) approach is used. The results of the activities showed that before giving education to farmers most of them had a level of knowledge of less than 63.3% and after providing education the knowledge of farmers increased to 76.7% had a level of knowledge of the category quite well. Based on statistical analysis it was stated that by providing education about modifying nutrition menus for families to prevent stunting in children meaningfully by using the FTAD (farmers team achievement division) approach.
“POVOS DA FLORESTA”! TRABALHO E EDUCAÇÃO ENQUANTO ESPAÇOS DEMOCRÁTICOS
Authors: Machado Rita de Cássia Fraga , Castro Amanda Motta
Published: December 2019

Este texto pretende discutir como, para os povos da floresta, a educação e o trabalho apresentam-se ao mesmo tempo como conquista e desafio na construção de espaços democráticos numa Amazônia que abrange a maior biodiversidade do planeta. A expressão “povos da floresta” nasceu com Chico Mendes. Retomada na segunda metade do século XIX, após a crise da borracha no Norte do país, remete ao processo de resistência empreendido não só pelos seringueiros e seringueiras, mas pelos povos extrativistas da Amazônia. A defesa de seu território sucessivamente foi motivo de sua organização e de suas lutas na condição de reprodução social e material da vida dos povos/mulheres da floresta. Chico Mendes é a figura emblemática e, ao mesmo tempo, inspiradora da luta, uma liderança que esteve presente e fez frente aos movimentos realizados em defesa da floresta. A defesa de um modo de vida digno e com qualidade para essa população era seu principal lema. Com a expropriação da indústria norte-americana dessas populações, foi necessário constituir um movimento de resistência dos seringueiros que, aos poucos, iam sendo “trocados” por “barões da borracha” e por imigrantes de outras regiões. Apesar de não ter deixado escritos sobre educação, pedagogia ou trabalho, Chico Mendes, com sua vida, ensinou a muitos sobre a importância da educação como sendo, na prática, um ato político. A ação educativa é estratégica no fortalecimento dessas populações.
AS ‘RAÍZES DA VERDADE’ NO PROÊMIO DO POEMA ‘DA NATUREZA’ DE PARMÊNIDES
Authors: Vanin Andrei Pedro
Published: December 2019

O texto procura evidenciar como algumas noções de verdade presentes, sobretudo, na Odisseia e na Ilíada, influenciaram a definição de verdade proposto no poema Da Natureza de Parmênides. A vasta literatura a respeito do tema, de modo geral, considera Parmênides o ‘divisor de águas’ entre a poesia e filosofia. Dada a importância filosófica do poema, ao enunciar pela primeira vez a identidade entre o ser e o pensar, esquece-se de ressaltar, no mais das vezes, fato não menos importante, a teoria literária subjacente ao poema, bem como as influências e semelhanças com os mitos precedentes. Sendo assim, parte-se de uma rápida caracterização do modo pelo qual a noção de verdade é apresentada em passagens específicas da Odisseia e da Ilíada. O segundo momento, apresenta rapidamente e de modo geral, a noção de verdade no poema de Parmênides, para após, buscar por contraste as semelhanças/dessemelhanças em relação aos poemas ditos homéricos, centrando-se a análise no proêmio do poema Da Natureza, onde pode-se ilustrar um contexto de teoria literária arcaica específico presente em ambos os textos a serem analisados, a saber: a adequação do assunto e estilo.

Margarita, está linda la mar (1998), del nicaragüense Sergio Ramírez, se nos ofrece como un universo ficticio de representaciones en el que se entretejen, en diferentes tiempos, los hechos y personajes históricos con hechos y personajes de la vida cotidiana, de manera que la historia pierde su condición estática para convertirse en la dinámica de la vida misma. La historia se conceptualiza como un proceso azaroso en el que la voluntad humana se enreda y no logra alcanzar a dibujarse metas distintas a las del azar. Solo una voluntad heroica puede intentar, apenas, contravenir el destino y modificar el devenir de la historia.

Ведення мисливського господарства є невід'ємною складовою частиною суспільного використання природних ресурсів. Це особлива галузь, що розвивалася одночасно із розвитком людини. Її вклад у сучасний стан людства важко переоцінити. Хоча самі тлумачення понять "мисливства", "полювання", "добування" давно змінили свою первозданну сутність та значення й у розвиненій цивілізованій системі еколого-економічних відносин переросли у поняття "ведення мисливського господарства". Це комплексний, складний, науковий підхід до охорони, відтворення та невиснажливого, раціонального користування ресурсами мисливських угідь і тварин. Ведення мисливського господарства мають провадити люди, що дійсно люблять природу і є спеціалістами своєї справи. При цьому особливу роль відводять державному регулюванню через відповідні важелі стимулювання раціонального ведення мисливського господарства. Одним з таких важелів має стати дієвий механізм справляння плати за спеціальне використання ресурсів мисливських угідь. У роботі досліджено підходи до визначення плати за спеціальне використання мисливських угідь та самого механізму справляння плати. Відзначено основні умови дієвості запропонованої методики та її недоліки. Запропоновано більш універсальну методику, яка є простішою для розрахунків та менш часозатратною.

Searching for Hot Subdwarf Stars from the LAMOST Spectra. III. Classification of Hot Subdwarf Stars in the Fourth Data Release of LAMOST Using a Deep Learning Method
Authors: Bu Yude , Zeng Jingjing , Lei Zhenxin , Yi Zhenping
Published: November 2019

Hot subdwarf stars are core He burning stars located at the blue end of the horizontal branch, which is also known as the extreme horizontal branch. The spectra of hot subdwarf stars can provide detailed information on stellar atmospheric parameters, such as the effective temperature, gravity, and abundances of helium, which can help clarify the astrophysical and statistical properties of hot subdwarf stars. These properties provide important constraints on the theoretical models of stars. The identification of hot subdwarf stars from the spectral data obtained by the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) can significantly increase the sample size and help us to better understand the nature of hot subdwarf stars. In this study, we propose a new method to select hot subdwarf stars from LAMOST spectra using convolutional neural networks and a support vector machine (CNN+SVM). By applying CNN+SVM to sample data selected from LAMOST Data Release 4 we obtain an F1 score of 76.98%. A comparison with other machine-learning algorithms, such as linear discriminant analysis and k-nearest neighbors, demonstrates that an approach based on CNN+SVM obtains better results than the others. Therefore it is a method well suited to the problem of searching for hot subdwarf stars in large spectroscopic surveys. Finally, we include an extensive discussion on how we determined the optimal hyperparameters of our proposed method.

In order to understand the diversity of classes observed in active galactic nuclei (AGNs), a geometrically and optically thick torus of gas and dust is required to obscure the central engine depending on the line of sight to the observer. We perform a simultaneous fitting of X-ray and mid-infrared (mid-IR) spectra to investigate whether the same structure could produce both emissions and, if this the case, to obtain better constraints for the physical parameters of the torus. In this case we take advantage of the fact that both emissions show important signatures of obscuration. We used the nearby type 2 active nucleus IC 5063 as a test object. This object is ideal because of the wealth of archival data, including some high-resolution data. It also has a relatively high AGN luminosity that dominates at both X-ray and mid-IR frequencies. We use high spectral resolution NuSTAR and Spitzer/IRS spectra. The AGN dusty models used several physically motivated models. We found that the combination of the smooth torus models at mid-IR by Fritz et al. and at X-rays by Baloković et al., with the viewing and half-opening angles linked to the same value, is the best choice to fit the spectra at both wavelengths. This allows us to determine all the parameters of its torus. This result suggests that the structure producing the continuum emission at mid-IR and the reflection component at X-ray is the same. Therefore, we prove that this technique can be used to infer the physical properties of the torus, at least when AGN dust dominates the mid-IR emission and the reflection component is significant at X-rays.

We present the results of the first transient survey from the Owens Valley Radio Observatory Long Wavelength Array (OVRO–LWA) using 31 hr of data, in which we place the most constraining limits on the instantaneous transient surface density at timescales of 13 s to a few minutes and at frequencies below 100 MHz. The OVRO–LWA is a dipole array that images the entire viewable hemisphere with 58 MHz of bandwidth from 27 to 84 MHz at 13 s cadence. No transients are detected above a 6.5σ flux density limit of 10.5 Jy, implying an upper limit to the transient surface density of 2.5 × 10−8 deg−2 at the shortest timescales probed, which is orders of magnitude deeper than has been achieved at sub-100 MHz frequencies and comparable flux densities to date. The nondetection of transients in the OVRO–LWA survey, particularly at minutes-long timescales, allows us to place further constraints on the rate of the potential population of transients uncovered by Stewart et al. From their transient rate, we expect a detection of

events, and the probability of our null detection is

, ruling out a transient rate >1.4 × 10−4 days−1 deg−2 with 95% confidence at a flux density limit of 18.1 Jy, under the assumption of a flat spectrum and wide bandwidth. We discuss the implications of our nondetection for this population and further constraints that can be made on the source spectral index, intrinsic emission bandwidth, and resulting luminosity distribution.
Molecular genetic studies of Chilean avifauna: an overview about current progress
Authors: Colihueque Nelson , Gantz Alberto
Published: November 2019

The biodiversity of Chilean avifauna has been shaped by geological events, geographical factors and extreme climatic regimens. Molecular genetic studies developed to date have begun to provide valuable information to elucidate the effect of these factors on the evolutionary history of Chilean birds. We conducted a search in two bibliographic databases (PubMed and Scopus) over the period between 1998 and 2018 to identify the number and class of articles published in this research field. The quantification of specific research categories was also performed to assess progress in different molecular genetic issues of Chilean birds. Representative studies of the more active research areas: population structure, phylogeography, systematics and taxonomy and genetic diversity, were briefly commented on. Studies on genetic divergence analysis of cryptic species and the underlying genetics at molecular level of adaptive phenotypes in populations, were very scarce. Several types of mitochondrial and nuclear markers have been used, with COI plus D-loop and microsatellite loci, respectively, being the most widely-used markers. However, high-throughput analyses based on complete mitochondrial genomes have also been published. More than one hundred species have been analyzed; the most studied groups being penguins, followed by New World swallows. Although, to date, molecular genetic studies of Chilean birds still require further analysis, the studies available on some species or groups have provided important data to improve our understanding of the origin and evolution of this avifauna.
Les nouvelles routes de la soie

Les « nouvelles routes de la soie » ont été lancées en 2013 par la Chine, mais n’ont vraiment démarré qu’en 2015. Elles sont ouvertes à tous les pays. Leur finalité est-elle impérialiste ? Elles visent plutôt à établir une hégémonie chinoise sur les plans économiques et politiques, en contrecarrant l’influence américaine. L’Europe occidentale est aussi affectée. Quel profit en tirer ? Quelles menaces ce projet recouvre-t-il ?
Ce que l’ open data fait à l’administration municipale
Authors: Courmont Antoine
Published: November 2019

Le développement des démarches d’ open data et de smart cities au sein de nombreuses métropoles met en lumière l’application des principes du libéralisme informationnel à l’échelle urbaine. À partir d’une enquête ethnographique au sein de la métropole de Lyon, cet article propose d’interroger ce que la mise en circulation des données fait à l’administration. Trois hypothèses sont poursuivies : Les politiques d’ open data catégorisent les données indépendamment des attachements qui les constituent. Cette catégorisation de la donnée comme entité libre et autonome permet de les rendre gouvernables et d’envisager une administration de la donnée qui dépasse l’organisation administrative et sectorielle de l’action publique. Toutefois, les attachements constitutifs des données viennent contrarier la mise en œuvre de cette administration transversale. Plutôt qu’une politique métropolitaine de la donnée, il faut envisager des politiques plurielles de données.
Global logistics network design problem with rules of origin
Authors: Ohmori Shunichi , Huang Qian , Yoshimoto Kazuho
Published: November 2019

Purpose: This paper aims to incorporate rules of origin into international taxation into firms' global operations. The purposes of this research are to develop a new model for the global logistics network design of an assembly system with rules of origin and to analyze how the changes of international relationships will affect logistics network design and evaluation functions.Design/methodology/approach: In this study, we develop a global logistics network design model prescribing allocating amounts for production, assembly, and distribution. A path-based programming model is presented that represents the complexities associated with international and interenterprise issues. The objective is to minimize total costs, which are costs of production, assembly, transportation, and customs duties. In addition to customs duties, rules of origin, which were, not addressed in previous studies, are considered. Several computational experiments with industrial examples are presented to validate the model.Findings: The results indicate that the tax planning and alignment with the FTA might have a significant impact on the decision-making in the global supply chain for multi-national operating companies. Therefore, the multi-national operating companies need to be aware of importance of what-if simulation before or after FTA changes.Originality/value: While designing global supply chain, the tax effects and use of free-trade agreements (FTAs), were generally omitted. In this paper, we proposed a global logistics network design model with rules of origin. We show the effectiveness and necessity to consider rules of origin. This model can be used in making an optimal global logistics network for global companies. The results of this model are used as a target for a real optimal logistics network. Companies can make a better logistics network by using this model.
IDENTIFICATION OF TECHNOLOGIES AND PROCESSES TO ENHANCE THE SUSTAINABLE DESIGN, MANUFACTURE, OPERATION, AND END-OF-LIFE OF THE MOTOR YACHT ABOVE 24 METERS
Authors: Liang M , Birmingham R
Published: November 2019

Sustainable development is a continuing concern in the Superyacht Industry due to the pressure on not only minimizing environmental impact but also considering economic viability and social acceptability. It is possible to enhance efficiency and effectiveness of resource use in manufacture, operation and recycle by identifying the sustainable technologies at the design stage. However, there is a lack of a holistic method to measure sustainable performance over the life cycle of the motor yacht during the technologies selection. A Life Cycle Sustainability Assessment (LCSA)based Sustainable Value Added (SVA) method has been developed to measure the sustainable performance for each technology using on the motor yacht over 24 meters. It is a new approach using the financial measure to aggregate data with existing economic terms to communicate with the investor with one language. This paper presents a systematic method and process to guide designer and owners to select and invest relatively sustainable solutions for the motor Superyacht.

Authors: Vinodkumar T. , Chandrasekaran M. , Vivek P. , Arunkumar S. , Padmanabhan S.
Published: December 2019

This study motivates the state of relying on the non-degradable plastic packaging to develop the alternative material namely reinforced poly lactic acid (PLA) with snake grass fibre (SG) and sisal fibre (SF) bio composite. Injection moulding fabrication method is used. For mechanical characterization, SG/SF is loaded with an effect from 10 to 30 wt.%. Similarly, the tensile and flexural properties are significant to improve the attained wt. % of SG/SF. Additionally, PLA-SG/SF bio composite produced is having high specific strength and specific modulus. The suggested one in SG/SF may be integrated into PLA to reduce the mass of the end product and substantially reduce the cost of raw materials. The impact strength tends to decrease with SG/SF content. Finite element analysis was carried out to correlate the experimental values.

Turbocharger matching is a process of matching a turbocharger to the desired engine. Many methods were proposed to perform the best match but they failed at certain cases. Due to inherent character of centrifugal compressor less torque develops poor transient response compared to naturally aspired engine. The mismatch of turbocharger will lead to poor performance. This research adapts, on road test based data logger turbomatching. In this investigation the matching performances of different turbochargers with a TATA truck engine was analysed. Five different routes included were for testing the match performance, the speed was varied at four levels from minimum to maximum, the load on the vehicle was varied at 6 levels from no load to full load. All the observations were superimposed on the respective compressor map and the match performance was analysed and the best match was suggested.
