Purpose: To report the case of a patient with adrenocorticotropic hormone (ACTH)-producing pituitary adenoma who developed a mental disorder after initial surgery that kept him from undergoing scheduled follow-up visits and who ultimately had a giant recurrent tumor that resulted in blindness. Case Report: A 37-year-old male presented with the primary complaint of decreased visual acuity (VA) in both eyes and visual field defects. Visual field examination revealed bitemporal hemianopia. Magnetic resonance imaging (MRI) showed a pituitary tumor of approximately 4 cm in diameter extending from the intrasellar region to the sphenoid sinus and the suprasellar region. Transnasal transsphenoidal surgery was performed. Immunostaining of tumor tissue collected intraoperatively showed ACTH-positive cells, thus leading to the diagnosis of ACTH-producing pituitary adenoma. Postoperatively, the patient reportedly developed mental disorder that possibly interfered with scheduled appointments or continuous follow-up visits for many years, so we had no postoperative data about the vision/visual filed. Seven years later, he presented with markedly decreased VA (i.e., no light perception) in both eyes. Fundus examination showed bilateral marked optic disc atrophy. MRI showed a larger than 8-cm diameter giant recurrent pituitary adenoma in the suprasellar region, for which craniotomy was performed for partial tumor resection. Preoperatively, his blood cortisol level was low, and the lesion was deemed a nonfunctioning pituitary adenoma. Postoperatively, no significant complications occurred, yet his VA was no light perception OD and light perception OS. Conclusions: Clinicians should be aware that patients with ACTH-producing pituitary adenomas may develop a mental disorder following surgery and possibly be unable to undergo scheduled follow-up, thus illustrating the importance of establishing an adequate patient follow-up system.
Sensitivity analysis of simplified low cost converging thermal wave technique for thin bilayer solid
Authors: Husin M. Shahril Shahril Bin
Published: March 2020

In this paper, the sensitivity analysis of thermo physical parameters of the semi-infinite bilayer was presented by using a simplified converging thermal wave model. This is done under the consideration that radial flow of converging thermal wave substantially dominates in the first layer and axial thermal wave, dominates in the second layer. The sensitivity of the correlated parameters due to the 5%, 10% and 100% of increment were evaluated.. The results of the calculated temperature were simulated by Mathematica software, in order to generate a sensitivity analysis and examined by graphs. From this analysis, we concluded the optimum conditions, hence to be applied in the real experiment. Our merit on this report is for introducing a simple method of optical transient heating by using low cost equipment such as camera’s flash lamp and thermocouple, which may also apply to the short pulse laser measurement. A brief theory of the present work is presented and the results obtained from the simulation are discussed.

Authors: Eseosa Omorogiuwa , S.O Onohaebi
Published: March 2020

Economic generation scheduling determines the most efficient and economic means of dispatch of generated energy to meet the continuously varying load demand at the most appropriate minimum cost, while meeting all the units equality and inequality constraints in  power network. This is currently not applicable in Nigeria power network. The network under study consists of seventeen (17) generating stations (Existing Network, National Integrated Power Projects and the Independent Power Producers). This work investigates economic generation and scheduling in Nigeria 330KV integrated power network at minimum operating cost using the classical kirmayer’s method and Artificial Neural Network (ANN) for its optimization in Matlab environment. ANN is trained to adopt its pattern at different load demands and acquires the ability to give load demand as soon as the set target and goal tends to equality. Cost function for each generating unit as well as a model for economic generation scheduling was developed.

Authors: Bennet M. Anto , Babu G. Sankar , Mekala S. , Natarjan S. , Srinivasan N.
Published: March 2020

This study proposes an approach for automatic detection of Ground glass pattern, a lung disease, from Computed Tomography (CT) and High Resolution Computed Tomography (HRCT) scans of the lung. The algorithm is based on frequency spectrum analysis of image using Gabor filter bank. Gabor filter banks are used to support the frequency extraction process. These algorithms when applied to HRCT images will assist doctors to gain more information than from the CT images. The tasks are completed in three steps: Preliminary mask formation, Peripheral mask formation and finally post processing. By these, higher sensitivity and selectivity may be achieved with fast processing time. In the post processing, binary noise removal technique is used to remove noise from the detection mask.

Authors: Angeline A Anitha , J Jayakumar
Published: March 2020

The performance of (Bi2Te3-PbTe) hybrid thermoelectric generator (TEG) composed of n-type Bismuth Telluride and p-type Lead Telluride semiconductor materials is presented in this paper.  The effect of different performance parameters such as output voltage, output current, output power, maximum power output, open circuit voltage, Seebeck co-efficient, electrical resistance, thermal conductance, figure of merit, efficiency, heat absorbed and heat removed based on maximum conversion and power efficiency have been theoretically analyzed by varying the hot side temperature of the hybrid thermoelectric generator up to 350oC and by varying the cold side temperature from 30oC to 150oC. The results showed that a maximum power output of 21.7 W has been obtained with the use of one hybrid thermoelectric module for a temperature difference of 320oC between the hot and cold side of the thermoelectric generator at matched load resistance. The figure of merit was found to be around 1.28 which makes its usage possible in the intermediate temperature (250oC to 350oC) applications such as heating of Biomass waste, heat from Biomass cook stoves or waste heat recovery etc. It is also observed that the hybrid thermoelectric generator offers superior performance over 250oC of the hot side temperature, compared to standard Bi2Te3 modules.

Authors: Deepa S. , Nithya K. P. , Sekar C. S. Ajin , Deepalakshmi V.
Published: March 2020

This paper deals with various power issues such as voltage sag, swell, harmonics, and surges using static synchronous compensator (STATCOM).The conventional controller suffers from uncertain parameters and non-linear qualities. However they are computationally inefficient extending to optimize the fuzzy controller (FC) parameters, since they exhaustively search the optimal values to optimize the objective functions. To overcome this drawback, a genetic algorithm (GA) based Fuzzy controller parameter optimization is presented in this paper. The GA algorithm is used to find the optimal fuzzy parameters for minimizing the objective functions. The feasibility of the proposed GA technique for distribution systems to improve the sag and total harmonic Distortion (THD) as major power quality indices in sensitive loads at fault conditions has been simulated and tested. Therefore, the multi-objective optimization algorithm is considered in order to attain a better performance in solving the related problems.

Authors: Duth P Sudharshan , Viswanath Vimal , Sreekumar Pankaj
Published: March 2020

Advances in medical imaging technologies have given rise for effective diagnostic procedures. The acquisition promptness and resolution enhancements of imaging modalities have given physicians more information, less invasively about their patients. Active contours are used to segment, match and track images of an atomic structure by manipulating constraints derived from the image data together with prior knowledge about the location, size, and shape of these structures. The level set method is referred as a part of active contour family. The major disadvantages of level set method are initialization of controlling parameters and time complexity. The proposed method adopts Robust Spatial Kernel Fuzzy C-Means (RSKFCM) and Lattice Boltzmann Method (LBM) to overcome these drawbacks. RSKFCM is based on standard Fuzzy C-Means algorithm which uses Gaussian RBF kernel function as distance metric and incorporates spatial information. The LBM uses the energy function to determine and reduce the actual processing time which addresses the time complexity. The proposed system combines both RSKFCM and LBM to form a hybrid approach, and the system is tested on a large set of MRI brain images and the experimental results are found to be improved with respect to time complexity.

Authors: Mohan B.Murali , Reddy M.Pala Prasad , Lakshminarayana M.
Published: March 2020

In this paper, a straightforward strategy for tracking the maximum power (MP) accessible in the wind energy conversion system for dc microgrid is proposed. A three-phase diode bridge rectifier alongside a dc-dc converter has been utilized between the terminals of wind-driven induction generator and dc microgrid. Induction generator is being worked in self-energized mode with excitation capacitor at stator. The output current i.e., dc grid current act as a control variable to track the MP in the proposed WECS. In this manner, the proposed calculation for maximum power point tracking (MPPT) is autonomous of the machine and wind-turbine parameters. Further, a technique has been created for deciding the obligation proportion of the dc-dc converter for working the proposed system in MPPT condition utilizing wind turbine qualities, relentless state proportionate circuit of prompting generator and power balance in power converters. Circuit straightforwardness and basic control calculation are the significant points of interest of the proposed setup for supplying energy to the dc microgrid from WECS. The fruitful working of the proposed calculation for Fuzzy logic based  MPPT has been shown with broad exploratory results alongside the simulated values.

An Examination of the Impact of Power Sector Reform on Manufacturing and Services Sector in Nigeria: an Empirical Analysis
Authors: Ojiya Emmanuel Ameh , Chukwuemeka Ngwu Jerome , Daneji B.A. , Isiwu George Duhu
Published: March 2020

The main objective of this study is to empirically examine the impact of Power Sector Reform on Manufacturing and Services Sector in Nigeria between 1999-2016. The study employed secondary annual time series data sourced from World Bank database (2016). The methodology adopted for the study was Augmented Dickey-Fuller (ADF); a test for long-run relationship using ARDL Bounds Testing approach  with analysis of long-run and short-run dynamics in the model. A striking revelation from the study is the inverse relationship that exists between manufacturing output and electricity consumption in Nigeria within the period referenced. This negative relationship is not unconnected with widespread allegation of misappropriation of budgeted funds for the Power Sector by successive administrations in Nigeria since 1999.  It must be stated in clear terms that constant and consistent electricity generation, transmission and distribution is sine-qua-none for the growth of the national economy. Virtually all sectors of the economy depend on the supply of electricity to do business and so the lack of this vital ingredient of growth contributes in no small measure in stagnating economic growth and development. Efforts at reforming the power sector can only be fruitful when ALL stakeholders in the power sector including the political class put away their personal agendas and take the bull by the horn towards rescuing the nation from the looming danger of stagnant economic growth. Furthermore, there is the need for the Nigerian government to come up with new, better and alternative ways of improving energy generation and supply, as well as proper maintenance of electricity infrastructure in the country.
On the High Dimentional Information Processing in Quaternionic Domain and its Applications
Authors: Kumar Sushil , Kumar Tripathi Bipin
Published: March 2020

There are various high dimensional engineering and scientific applications in communication, control, robotics, computer vision, biometrics, etc.; where researchers are facing problem to design an intelligent and robust neural system which can process higher dimensional information efficiently. The conventional real-valued neural networks are tried to solve the problem associated with high dimensional parameters, but the required network structure possesses high complexity and are very time consuming and weak to noise. These networks are also not able to learn magnitude and phase values simultaneously in space.  The quaternion is the number, which possesses the magnitude in all four directions and phase information is embedded within it. This paper presents a well generalized learning machine with a quaternionic domain neural network that can finely process magnitude and phase information of high dimension data without any hassle. The learning and generalization capability of the proposed learning machine is presented through a wide spectrum of simulations which demonstrate the significance of the work.

Authors: Prashar Deepak , Jyoti Kiran , Kumar Dilip
Published: March 2020

Advancements in wireless communication technology have empowered the researchers to develop large scale wireless networks with huge number of sensor nodes. In these networks localization is very active field of research. Localization is a way to determine the physical position of sensor nodes which is useful in many aspects such as to find the origin of events, routing and network coverage.  Locating nodes with GPS systems is expensive, power consuming and not applicable to indoor environments. Localization in three dimensional space and accuracy of the estimated location are two factors of major concern. In this paper, a new three dimensional Distributed range-free algorithm which is known as CP-NR is proposed. This algorithm has high localization accuracy and resolved the problem of existing NR algorithm. CP-NR (Coplanar and Projected Node Reproduction) algorithm makes use of co-planarity and projection of point on plane concepts to reduce the localization error. Results have shown that CP-NR algorithm is superior to NR algorithm and comparison is done for the localization accuracy with respect to variations in range, anchor density and node density.
Energy and Load Aware Routing Protocol for Internet of Things
Authors: Sankar S. , Srinivasan P.
Published: March 2020

Maximizing the network lifetime is one of the major challenges in Low Power and Lossy Networks (LLN). Routing plays a vital role in it by minimizing the energy consumption across the networks through the efficient route selection for data transfer. IPv6 Routing Protocol for Low Power and Lossy Networks (RPL) is a IETF standardized IPv6 routing protocol for LLN. In this paper, we propose Energy and Load aware RPL (EL-RPL) protocol, which is an enhancement of RPL protocol. It uses a composite metric, calculated based on expected transmission count (ETX), Load and battery depletion index (BDI), for the route, selection. The COOJA simulator is used for performance evaluation.  EL-RPL is compared with other similar protocols RER(BDI) RPL and fuzzy logic based RPL (OF-FL RPL). The simulation result shows that the EL-RPL improves the network lifetime by 8-12% and packet delivery ratio 2-4%.
A categorical data analysis of impact of biogas on women of rural households – with examples from Nepal
Authors: Devkota Jyoti U.
Published: March 2020

This paper is based on primary data collected from 400 households of biogas consumers. A detailed structured questionnaire was developed and pretested. Here response to each question was given as a multiple choice option resulting in more than 450 categorical data. These variables studied various aspects of households using biogas. The results focused on women of these households. Interrelationships between several other variables including the role of a woman in various decisions related to the plant were analyzed. Logistic regression of decision making of woman on several variables including asset index of the family was done. This asset index was calculated from the principle component analysis of socio-economic variables. The family dynamics in the choice of biogas as renewable energy source was quantified using odds ratio and regression coefficients. The interdependence between variables was tested using Chi square test of Independence of Attributes. A novel data based approach of generation and analysis of categorical data is demonstrated here. The suitability of generation of categorical data in the absence of accurate measurement instruments is highlighted. This method is also suitable for countries without a strong backbone of good quality official records, and provides a good backup data for official statistics.

Evaluation of shale volume and effective porosity using larionov and archie equations from wire-line logs, Niger delta Nigeria
Authors: Aka Mfoniso U. , Ibuot Johnson Cletus , Okeke Francisca N.
Published: March 2020

In Niger Delta region of Nigeria, reservoirs are mostly loose and unstratified sands to hold fluids. In this paper, three different wells in central Niger Delta were assessed for shale volume and actual porosity. The results of the analysis delineate the presence of sand, sand-shale and shale formations. Hydrocarbon prospecting was found to be strong in sand, moderate in sandshale and shallow in shale respectively. However, existent of shale lessens effective porosity and water saturation of the rock formations. The extent of the formation extends from 1300 to 2500 m. Shale volume and actual porosity values extend from 0.00 to 0.302 dec and 0.047 to 0.302 dec which decrease with increasing depth. Comparably, the water saturation and water resistivity extend from 0.432 to 0.779 dec and 0.106 to 2.918 Ohm respectively. These values of actual porosity are strong in sand, moderate in sand-shale and shallow in shale formations. The results from this assessment proof well log a vital and easier tool in assessing of reservoir properties.

Published: March 2020

The usage of fossil fuels is actually not good for living nature and in future, this limited source of energy will vanish. Therefore, we need to go with the clean and renewable source of energy such as wind power, solar energy etc. In this paper, we are concentrating in wind power through optimizing the wind turbine placement in wind farm. The area-of-convex hull, maximize ‘output power’ and minimum spanning tree distance are our main objective topics, due to their effect in wind farm design. An implementation of modified version of the wind turbine (WT) placement model is uses to estimate the yields of the (wind farm) WF layouts and for simplifying the behavior of wind field, in this paper we uses a simple wake approach. Moreover, to resolve the multi-objective problem here we proposed (Modified Genetic Algorithm) MGA, which is considerably better than the (Genetic Algorithm) GA and for evaluate the performance of MGA we use the multi-objective (EA) evolutionary algorithms such as; Genetic algorithm (GA) and SPEA2 and, produce different number of WT layouts. These methodologies are consider with various ‘problematic specific operators’ that are present in this paper.
Design and implementation of an effective web-based hybrid stemmer for Odia language
Authors: Jena Gouranga Charan , Swarup Rautaray Siddharth
Published: March 2020

Stemmer is used for reducing inflectional or derived word to its stem. This technique involves removing the suffix or prefix affixed in a word. It can be used for information retrieval system to refine the overall execution of the retrieval process. This process is not equivalent to morphological analysis. This process only finds the stem of a word. This technique decreases the number of terms in information retrieval system. There are various techniques exists for stemming. In this paper, a new web-based stemmer has been proposed named as “Mula” for Odia Language. It uses the Hybrid approach (i.e. combination of brute force and suffix removal approach) for Odia language. The new born stemmer is both computationally faster and domain independent. The results are favourable and indicate that the proposed stemmer can be used effectively in Odia Information Retrieval systems. This stemmer also handles the problem of over-stemming and under-stemming in some extend.

“Há coisas pelo meio”
Authors: Pereira Patrícia Resende
Published: March 2020

A poesia dos autores portugueses Manuel Gusmão e João Miguel Fernandes Jorge é conhecida pela relação a ser estabelecida com outras artes. Dessa maneira, o intuito do texto é investigar a maneira como a imagem é evocada pela palavra poética, tendo em vista, para tanto, o conceito da écfrase. Definido inicialmente como a representação verbal de um objeto visual, a noção encontra-se ainda em discussão, uma vez que em muito tende a se associar ao suposto compromisso mimético. Assim sendo, como recorte para o texto aqui apresentado, seleciona-se dois poemas, um composto por Manuel Gusmão e outro por João Miguel Fernandes Jorge. No primeiro, que recebe como título apenas a sequência numérica XXIV, em correspondência a própria organização editorial de Mãe-do-fogo (2009), escrita por Jorge, tem-se a écfrase de uma das fotografias que compõe O amor na margem esquerda, de Ed van der Elsken, enquanto a segunda análise se centra no segundo poema da seção “as mãos, a tersa rima”, de Mapas/o assombro a sombra (1990), responsável por evocar Garota comendo pássaro (O prazer), de René Magritte. Assim sendo, tendo em vista imagens de natureza substancialmente distintas, o intuito da pesquisa é verificar a maneira com a qual a écfrase é realizada nos dois poemas.
Entre nomes partidos e corpos pro(s)téticos, as regras de um jogo duplo
Authors: Ferreira Gabriela Semensato
Published: March 2020

Em Double Game (1999/2007), Sophie Calle elabora um projeto colaborativo com Paul Auster a partir de um trecho de Leviathan(1992),do escritor norte-americano. No romance de Auster, a personagem Maria Turner, inspirada na vida e na obra dessa artista francesa, é apresentada. Ao analisar as “regras desse jogo”, Calle, por sua vez, insere o trecho sobre Maria em seu livro. Porém, realiza no texto operações de corte e enxerto, marcadas pela cor vermelha. Neste artigo, propomos pensar o excerto em questão como suplemento,avaliando como este transborda os limites da narrativa de Auster, e como articulam-se, nesse gesto ou jogo, linguagens e discursos diversos. Para isso, realizam-se recortes necessários, considerando, como parte do corpo ou corpustextual, trabalhos teórico-poéticos como Prosthesis (1995), de David Wills, e Gramatalogia (1973), de Jacques Derrida. Assim, sugerimos uma aproximação entre as ideias de “prótese” e “suplemento”, para propor formas de ver e de ler essas obras de arte a partir das duplicações e duplicidades que encenam. Trata-se, portanto, não apenas da noção de duplo, mas da ficção das “escrituras de si” desses artistas, e da tensão que se dá pela vinculação e divisão de nomes próprios em suas obras.

E quando nem os preceitos, nem a prática, nem a arte produzida são passíveis de uma classificação definitiva? E quando o fazer artístico consegue se desconectar da história, do tempo, e transitar livremente entre a palavra e o silêncio, entre a imagem e a transparência, a escultura e o vazio? Esses questionamentos talvez não deixassem o plano das abstrações se pelo concreto Haroldo de Campos não tivesse chegado à Mira Schendel. Nesta artista além-métodos e teorias e disposta a um esforço enorme, ao mesmo que sutil, para significar sua alma de artista em diferentes suportes expressivos, o desejo de dizer é latente. A nós, resta o prazer de escutá-lo.
Modulações hesitantes do olhar
Authors: Lucas Fabio Roberto
Published: March 2020

Destacando alguns momentos do meio século de escrita dos Cahiers de Paul Valéry, será possível observar como um conceito estético oriundo da música – a modulação – é transformado pelo poeta francês, sendo empregado já nos manuscritos da Introdução ao Método de Leonardo da Vinci para refletir sobre o olhar, a figura e o desenho. Com efeito, ao ser deslocada do universo musical para a artes plásticas, a ideia de modulação deixará de ser pensada como uma transição sucessiva entre tons de diferentes partes de uma obra para ser concebida como passagem hesitante, sucessiva e simultânea, entre múltiplas camadas heterogêneas da experiência estética. Desse modo, o ato de modular abrirá um campo de reverberações entre as diferentes artes no interior do qual o conceito de forma, longe de ser definido pela purificação analítica dos componentes elementares de um meio, suporte ou área de competência estética, refina-se nas hesitações e intervalos entre diferentes práticas e materiais artísticos. Assim, o diálogo entre o conceito valeryano de modulação e a artes plásticas poderá também precisar aspectos importantes do formalismo poético atribuído a Valéry.
Retratos inacabados
Authors: Otoch Janaína Nagata
Published: March 2020

O artigo discute o retrato que Pablo Picasso fez de Gertrude Stein (1905) para cotejá-lo com os retratos literários que Gertrude Stein fez de Picasso (1909-10, 1924). Examinando como as obras respondem ao imperativo de “matar o século XIX”, interrogamos como tanto em Picasso quanto em Stein opera-se uma mudança de paradigma em relação às exigências do retrato enquanto gênero, que acaba por instaurar um modelo de intersubjetividade em dissidência com antigas prescrições de objetividade pautadas por uma tradição da retratística que emergira com o Renascimento. A análise coloca em relevo os paralelismos entre a “destruição” do espaço perspectivo na pintura cubista e a “destruição” da sintaxe nos poemas de Stein, bem como a busca por simultaneidade e por uma apreensão não unitária e fixa de noções como sujeito e identidade, que Picasso e a escritora praticaram em seus respectivos meios de expressão. Por último, comentamos brevemente a versão em português de Augusto de Campos a partir da tradução de “If I Told You: A Complete Portrait of Picasso” [Se eu lhe contasse: um retrato inacabado de Picasso], o segundo dos retratos de Picasso escrito por Gertrude Stein.
Sherlockismos de “O Mistério”
Authors: De Almeida Leandro Antonio
Published: March 2020

O objetivo deste trabalho é analisar o humor na ficção policial brasileira da Primeira República, tomando como fonte principal o romance O mistério, escrito a oito mãos em 1920 por Afrânio Peixoto, Viriato Correia, Medeiros e Albuquerque e Coelho Netto. Nossa tese é que esse romance representa sobretudo a recepção da ficção policial difundida no país desde 1907. Focaremos a recepção dos textos policiais de Conan Doyle por terem marcado a imaginação dos leitores brasileiros. Sherlock Holmes ensejou imitadores de tal modo que suas deduções foram aplicadas pelos leitores de jornal e jornalistas na solução dos crimes noticiados na imprensa, servindo também de modelo à investigação policial, marcada por uma criminologia científica bastante difundida no período. Mostraremos como esses fenômenos estão presentes em O mistério, mobilizados para uma sátira da polícia e da sociedade brasileira.

O aprimoramento das comunicações nos Estados Unidos, nas primeiras décadas do século XX, tornou a imprensa um importante ator na política, sobretudo no campo da opinião pública. Com isso, jornais e revistas se configuraram vitrines das principais questões do país. Pela importância, a utilização dos jornais e revistas se constituiu instrumento de propaganda externa dos países interessados em aprimorar suas relações com os EUA, sobretudo no período da Segunda Guerra Mundial. Este artigo objetiva compreender, a partir da análise da documentação diplomática, o assédio dos profissionais da propaganda e jornalistas estadunidenses ao governo Vargas (1930-1945) por espaços pagos na imprensa estadunidense com objetivo de criar matérias jornalísticas favoráveis ao Brasil nos Estados Unidos.
César Lattes, José Leite Lopes e o nacionalismo científico no Brasil dos anos 1940
Authors: Tavares Heraclio Duarte , Videira Antonio Augusto Passos
Published: March 2020

Analisamos as ideias do grupo de físicos reunido em torno de César Lattes, que tinha nas propostas de José Leite Lopes o núcleo de uma concepção que via a ciência como base de um projeto nacional desenvolvimentista. Leite Lopes falava, publicamente, sobre a responsabilidade do cientista diante dos problemas do país, e, privadamente, o grupo formulava estratégias para ampliar o número de polos de ensino e pesquisa no Brasil. Ao analisar cartas, discursos e entrevistas destes físicos, percebe-se uma noção de pertencimento à coletividade brasileira mediada pela ciência que impulsionou o surgimento de uma identidade científica nacional, culminando na criação do Centro Brasileiro de Pesquisas Físicas (CBPF), em 1949, e do Conselho Nacional de Pesquisas (CNPq), em 1951. Sugerimos o uso da categoria “nacionalismo científico” como chave interpretativa da manifestação e tomada de consciência deste sentimento, que levou os sujeitos históricos a agirem na realidade para a materialização institucional da prática da física no CBPF atrelada à ciência como matéria de Estado no CNPq.
Entre França e Alemanha

Este artigo se propõe a explorar a dinâmica do universo cultural da Argentina na primeira metade do século XX a partir da observação da circulação de distintas atitudes intelectuais. Isso significa analisar, em paralelo às disputas teóricas entre positivistas e espiritualistas e suas reverberações institucionais, os estilos de vida que informavam as discordâncias teóricas. Parto da emergência de um grupo de intelectuais nacionalistas argentinos que ganha espaço a partir da radicalização do discurso crítico dos anos 1920, no intuito de analisar a decadência da referência francesa – grande orientadora das expectativas da elite letrada argentina da virada do século – e a ascensão de referências alemãs e espanholas que viabilizavam não apenas a divulgação de ideias novas, como também, de um novo “sentido do jogo” para os intelectuais argentinos.
Cinema científico
Authors: Silva Márcia Regina Barros da
Published: March 2020

O objetivo deste artigo é compreender o papel desempenhado pelo uso de imagens médicas na produção do cinema documental no Brasil, especificamente na trajetória do documentarista Benedito Junqueira Duarte. O cinema científico foi uma nova experiência visual sobre a qual Duarte construiu parte importante de seu percurso profissional. De 1940 a 1954 os filmes produzidos tiveram como tema principal a cultura nacional, com documentários que se referiam principalmente à educação, em associação com temas de saúde, saúde pública e espaço urbano. De fins dos anos 1950 até fins dos anos 1960, Duarte passou a realizar documentários com médicos de diferentes instituições paulistas e com diferentes laboratórios nacionais e internacionais, com grande repercussão na área da cirurgia cardíaca, momento de consolidação de um novo campo de especialização médica que também se instituía no país.
Lagrangian Analysis of Tropical Cyclone Genesis Simulated by General Circulation Models Compared with Observations
Authors: Song Chanwoo , Park Sungsu , Shin Jihoon
Published: March 2020

As a contribution to understanding the genesis of tropical cyclones (TCs), we compared TC genesis processes simulated by the Seoul National University Atmosphere Model version 0 with a Unified Convection Scheme (SAM0) and the Community Atmosphere Model version 5 (CAM5) with those from the ERA-Interim reanalysis (ERA-Interim, hereafter ERAI) and best track observations. In contrast to previous studies that estimated the TC genesis potential using the Eulerian mean environmental conditions, we calculated the probability of a pre-existing weak cyclonic embryo vortex (EV) developing into a TC by analyzing changes in the environmental conditions along the EV trajectories. Our analysis indicates that the spatial distribution and annual cycles of TCs obtained from the SAM0 and ERAI are similar to those obtained from the best track observation data. With the exception of the mesoscale convective organization and associated variables, most environmental variables along the trajectories of DEVs (EVs developing into TCs) showed monotonic variations. When EVs were born, environmental conditions of DEVs were significantly different from those of nondeveloping EVs, allowing for the prediction of TC genesis. In general, TC genesis probability increased as the environment became more cyclonic, moist, unstable, and with a weaker wind shear. Rapidly strengthening EVs were more likely to develop into TCs. SAM0 and ERAI have the same combination of environmental variables with the best prediction skill for TC genesis—absolute vorticity at 850 hPa, column saturation deficit, sea surface temperature, vertical shear of horizontal winds between 200 and 850 hPa, and latitude—with similar sensitivities to individual environmental variables, indicating that SAM0 well simulates the observed TC genesis processes.

Published: March 2020

Objectives:

To evaluate volume changes within the tongue post chemoradiation therapy (CRT)

Study Design:

Retrospective review

Setting:

Academic Medical Center

Subjects and Methods:

Subjects included 19 patients that received CRT as the primary treatment for tonsillar or hypopharynx squamous cell carcinoma. Tongue volumes were calculated by three raters from thin slice computed tomography images collected before treatment and up to 29 months post-CRT. Body mass index (BMI) was also collected at each time point.

Results:

Inter-rater reliability was high with an ICC of 0.849 (95% CI = 0.773, 0.905). Linear mixed effects modeling showed a mean decrease of 0.45 cm3 (standard error of the mean [SEM] = 0.11) in tongue volume per month post-CRT ( P < .001). However, the addition of BMI to the model was significant (χ2 (4) = 25.0, P < .001), indicating that BMI was a strong predictor of tongue volume, with a mean decrease of 1.75 cm3 (SEM = 0.49) in tongue volume per unit decrease in BMI ( P < .001) and reducing the post-CRT effect on tongue volume decrease per month to 0.23 cm3 ( P = .02). BMI significantly ( P < .001) decreased by 0.11 units (SEM = 0.02) per month post radiation.

Conclusion:

Tongue dysfunction and decreased tongue strength are significant contributors to the dysphagia that patients experience after receiving CRT. In this study, both tongue volume and BMI decreased post-CRT; therefore, BMI could potentially be used as a predictor of tongue volume post-CRT.
Diversified Portfolio Model of Adaptability: A Natural History Perspective
Authors: Leong Frederick T. L.
Published: March 2020

Using a natural history perspective, the diversified portfolio model (DPM) of adaptability developed by Chandra and Leong (2016) is described in this article as a representation of the latter author’s life work in researching diversity and adaptability. The primary thesis of the DPM is that a diversified portfolio of activities, roles, and experiences will lead to greater adaptability in life. The DPM was intended to address a gap in the literature by illuminating the antecedents of adaptive processes that have been studied in current models, including those for self-complexity, risk and resilience, and self-efficacy. This description is followed by an example of the application of the DPM in academic careers. The mechanisms underlying the DPM are then discussed in relation to mental models and mindfulness. Next, the negative effects of nondiversification are illustrated with examples of workaholism and loneliness. Finally, the DPM is linked to the author’s own diversified portfolio of roles and activities to illustrate its positive impact.
Il percorso socialista di Gabriele D’Annunzio tra storia e letteratura
Authors: Alosco Antonio
Published: March 2020

La complessa personalità di Gabriele D’Annunzio, in una costante sincronica evoluzione della produzione letteraria con l’attivismo politico, ha attraversato un periodo – spesso dimenticato dai critici – di vicinanza alle idee socialiste. Attratto dalla vitalità e dalle idee progressiste della sinistra che rispondeva alle leggi liberticide e reazionarie di Pelloux, se ne fece influenzare sia nel periodo dell’impresa fiumana, che in una prima fase di contestazione al fascismo, appoggiando la sinistra radicale. Influssi dannunziani si ritrovano, in quel periodo, nel linguaggio adottato dall’ Avanti! e nell’apprezzamento che anche ambienti socialisti dimostrarono per l’opera letteraria del Vate.

Dopo il 1906 le strade dei socialisti e di D’Annunzio si divaricarono fino a contrapporsi. D’Annunzio rilanciò le posizioni nazionalistiche e, al rientro in Italia dopo il soggiorno in Francia tra il 1904 e il 1915, condusse un’attività politica tradottasi, nelle fasi iniziali della Prima guerra mondiale, nel sostegno attivo dei movimenti interventisti, poi nella partecipazione attiva sul campo come “uomo d’arme”, e da ultimo nelle azioni postbelliche degli irredentisti. Le imprese “rivoluzionarie” del poeta affascinarono anche alcune frange del socialismo italiano e l’impresa di Fiume, realizzata in collaborazione con il socialista Alceste De Ambris, raccolse gli elogi di Lenin e produsse la Carta del Carnaro, costituzione che conteneva elementi avanzati di matrice socialista.
Public managers’ perception of exploitative and explorative innovation: an empirical study in the context of Spanish municipalities
Authors: Barrutia Jose M. , Echebarria Carmen
Published: March 2020

This article studies the contribution of exploitative and explorative innovation to the perceptions of economic and social value of local authorities in charge of sustainability-related innovation. The model proposed is tested capturing the perceptions of 656 local authorities. The research findings contribute evidence of complex linkages between innovation forms (i.e. exploitative and explorative) and facets of perceived value. Overall, the link between the perceptions of both forms of innovation and economic value fits March’s (1991) view. A positive effect of both exploitative and explorative innovation on economic value is found, coupled with a negative interaction effect. The influence of exploitative innovation is stronger than that of explorative innovation. However, this is only part of the story. We also consider the link between exploitative/explorative innovation and one additional facet of value: social value (in the form of network identification). The roles of both predictors are virtually opposite: identification is mostly explained by explorative innovation, rather than exploitative innovation. The social value dimension considered in this research adds an explanation as to why public organisations may focus on exploration or combine both exploitation and exploration.

Points for practitioners

• Public managers may focus on exploitative innovation (when economic value considerations are dominant) and on explorative innovation (when social value thinking prevails), or combine both activities. • Network promoters should not assume that public managers favour exploitative innovation over explorative innovation.
