O extrato de tomate é o produto elaborado a partir de tomates firmes, em ponto de maturação adequado e livres de materiais estranhos. A cor do produto é determinada pelos pigmentos carotenoides e guia a preferência do consumidor. O objetivo desta pesquisa foi avaliar as características físico-químicas (pH, acidez e ºBrix), teor de licopeno e ?-caroteno de extratos de tomates comercializados em lata e em pote de vidro. As características físico-químicas, os teores de pigmentos licopeno e ?-caroteno foram determinados a 25ºC, em triplicata. As informações obtidas indicaram que existem diferenças relativas às características físico-químicas (acidez total e sólidos solúveis totais) de extrato de tomate embalado em lata e pote de vidro comercializado no mercado. Todas as três marcas A, B e C apresentaram sólidos solúveis totais abaixo do preconizado pela legislação brasileira para extratos de tomates. Não foram obtidas diferenças expressivas para teor de pigmentos (licopeno e ?-caroteno) para o extrato comercializado nesses dois tipos de embalagens.

Authors: Coelho dos Santos Aline , Santos Fernandes Fabiana , Bento da Silva Juarez
Published: August 2019

Esta pesquisa trata de uma revisão sistemática da literatura sobre a aplicação de laboratórios virtuais e remotos (LVR) em processos didáticos no ensino de ciências, traçando paralelo entre esse tipo de aplicação na educação básica e no ensino superior. Para sua efetivação, foi realizada uma análise descritiva e bibliométrica em 43 artigos das bases SCOPUS, Web of Science e ProQuest, observando as disciplinas, áreas de conhecimento, níveis de ensino e os locais onde os laboratórios estão sendo explorados. Assim, evidenciou-se que as aplicações de LVR são muito mais presentes no ensino superior, principalmente nas áreas de Engenharia. No entanto, as aplicações realizadas na educação básica demonstraram que esse é um campo em potencial para ser mais explorado, por apresentar resultados positivos, capazes de suprir, mesmo que em parte, a carência de recursos, o desinteresse e a desmotivação apresentados pelos alunos, atualmente, no contexto escolar.

Authors: Ponciano de Oliveira Lima Diego
Published: August 2019

A transformada de Fourier é utilizada para decompor uma imagem nas suas componentes de frequência para vários tipos de processamento digital de imagens como filtragem, compressão e restauração. Os métodos de processamento de imagem proporcionam grandes avanços em diversas áreas de conhecimento, como na Medicina, em que diagnósticos médicos são feitos com a análise de imagens que necessitam de tratamento, como a filtragem. Em imagens coloridas de marca d’água, são necessários tratamentos com filtros de modo que a imagem não tenha ruídos ou até mesmo a compressão dessas imagens, de tal modo que quando houver uma descompressão não haja erros. Hoje, técnicas de filtragem de imagem colorida são representadas por rotações no espaço de cores tridimensional. Tais rotações são facilmente representadas pela álgebra dos Quatérnios de Hamilton. O presente trabalho analisa as várias aplicações da transformada quaterniônica de Fourier no processamento de imagens, mostrando a eficácia da transformada quaterniônica de Fourier comparada com a transformada de Fourier convencional.

Cryptography is a mathematical science which permits only the authorized users to access the data. Today, it is necessary for our routine life to safeguard online data like credit card numbers, bank transactions, etc. Many cryptographic algorithm-based data security mechanisms have been introduced by various researchers for protecting the online / M-Commerce data. Even though, no data security algorithms achieved the required security level with less time. For overcoming these issues, we propose a new data security algorithm called Elliptic-Curve Cryptography and Diffie-Hellman based data security algorithm for securing the M-Commerce data. Here, the key size of the Elliptic Curve Cryptography is less than RSA that will be helpful to improve the efficiency and reduce the storage space. This algorithm is able to establish a secure session key through a server over an insecure channel and also handle various illegitimate users. In addition, this new algorithm is more secure, efficient and suitable for mobile commerce environments than existing data security algorithms. For evaluating the data security mechanism, many experiments conducted with M-Commerce data that are collected from the Internet which are freely available and also proved the efficiency of the data security algorithm.

Road network segmentation from high resolution satellite imagery have profound applications in remote sensing. They facilitate for transportation, GPS navigation and digital cartography. Most recent advances in automatic road segmentation leverage the power of networks such as fully convolutional networks and encoder-decoder networks. The main disadvantage with these networks is that they contain deep architectures with large number of hidden layers to account for the lost spatial and localization features. This will add a significant computational overhead. It is also difficult to segment roads from other road-like features. In this paper, we propose a road segmentation architecture with an encoder and two path decoder modules. One path of the decode module approximates the coarse spatial features using upsampling network. The other path uses Atrous spatial pyramid pooling module to extract multi scale context information. Both the decoder paths are combined to fine tune the segmented road network. The experiments on the Massachusetts roads dataset show that our proposed model can produce precise segmentation results than other state-of-the-art models without being computationally expensive.

Authors: Kraujalienė Lidija
Published: August 2019

Purpose – to find appropriate tools to measure the efficiency of the technology transfer process (TTP) in higher education institutions (HEIs). Scientific problem is a lack of methods measuring the efficiency of TTP. The objective – comparative analysis of efficiency evaluation methods.

Research methodology – the research methodology is based on a comparative analysis of the research papers on the advantages and disadvantages of methods suitable to evaluate the efficiency of TTP.

Findings – among some tools, FARE is highlighted for identifying the variables of TTP and assigning their weights, when TOPSIS – to rank the variables and identify the most important. MULTO-MOORA and COPRAS methods with ranking abilities are suitable to select the number of HEIs. DEA method is intended for the economic evaluation of TTP efficiency in HEIs. The social sciences are strengthened by suitable founded tools to measure the efficiency of TTP in HEIs.

Research limitations – this paper is providing all advantages and disadvantages (limitations) of decision-making multicriteria methods.

Practical implications – the original structure of methods enabling stakeholders (HEIs, TTOs and public authorities) for efficient allocation of an organisation’s financial resources, foresee the future goals for improving the efficiency of TTP.

Originality/Value – the original framework of methods incorporated into the one model, enabling related stakeholders (HEIs, TTOs and public authorities) allocate financial resources efficiently.
The Structure of the Orion Nebula in the Direction of θ1 Ori C

Published: August 2019

We have used existing optical emission and absorption lines, [C ii] emission lines, and H i absorption lines to create a new model for a central column of material near the Trapezium region of the Orion Nebula. This was necessary because recent high spectral resolution spectra of optical emission lines and imaging spectra in the [C ii] 158 μm line have shown that there are new velocity systems associated with the foreground Veil and the material lying between θ
1 Ori C and the main ionization front of the nebula. When a family of models generated with the spectral synthesis code Cloudy were compared with the surface brightness of the emission lines and strengths of the Veil absorption lines seen in the Trapezium stars, distances from θ
1 Ori C were derived, with the closest, highest ionization layer being 1.3 pc. The line-of-sight distance of this layer is comparable with the size of the inner Huygens region in the plane of the sky. These layers are all blueshifted with respect to the Orion Nebula Cluster of stars, probably because of the pressure of a hot central bubble created by θ
1 Ori C's stellar wind. We find velocity components that are ascribed to both sides of this bubble. Our analysis shows that the foreground [C ii] 158 μm emission is part of a previously identified layer that forms a portion of a recently discovered expanding shell of material covering most of the larger Extended Orion Nebula.
Differential Interferometric Signatures of Close Binaries of Supermassive Black Holes in Active Galactic Nuclei

In the present paper, we explore opportunities of applying the GRAVITY at the Very Large Telescope Interferometer with unprecedented spatial resolution to identify close binaries of supermassive black holes (CB-SMBHs) in active galactic nuclei (AGNs). Each supermassive black hole is assumed to be separately surrounded by its own broad-line regions (BLRs) composed of clouds with virialized motion. Composition of the binary orbital motion and the virial motion of clouds in each BLR determines the projected velocity fields and hence differential phase curves, which are obviously different from that of a single BLR. We calculate emission line profiles and differential phase curves of CB-SMBHs for the GRAVITY. For the simplest case, in which angular momenta of two BLRs and orbital motion are parallel, a phase plateau generally appears in the phase curves. For other combinations of the angular momentum, the plateau is replaced by new peaks and valleys variously depending on the situation. Given a combination, phase curves are also sensitive to changes of parameters of CB-SMBHs. All these features are easily distinguished from the well-known S-shaped phase curves of a single BLR, so that the GRAVITY is expected to reveal signals of CB-SMBH from candidates of AGNs. With joint analysis of observations of reverberation-mapping campaigns, we can reliably identify CB-SMBHs, and measure their orbital parameters in the meanwhile. This independent measurement of the orbital parameters also has implications to analysis of pulsar timing array observations for properties of low-frequency gravitational waves in future.

Supernova neutrinos are crucially important to probe the final phases of massive star evolution. As is well known from observations of SN 1987A, neutrinos provide information on the physical conditions responsible for neutron star formation and on the supernova explosion mechanism. However, there is still no complete understanding of the long-term evolution of neutrino emission in supernova explosions, although there are a number of modern simulations of neutrino radiation hydrodynamics, which study neutrino emission at times less than one second after the bounce. In the present work we systematically calculate the number of neutrinos that can be observed in Super-Kamiokande over periods longer than 10 seconds using the database of Nakazato et al. anticipating that neutrinos from a Galactic supernova can be detected for several tens of seconds. We find that for a supernova at a distance of 10 kpc, neutrinos remain observable for longer than 30 s for a low-mass neutron star (1.20 M
⊙ gravitational mass) and even longer than 100 s for a high-mass neutron star (2.05 M
⊙). These scenarios are much longer than the observations of SN 1987A and longer than the duration of existing numerical simulations. We propose a new analysis method based on the cumulative neutrino event distribution as a function of reverse time from the last observed event, as a useful probe of the neutron star mass. Our result demonstrates the importance of complete modeling of neutrino light curves in order to extract physical quantities essential for understanding supernova explosion mechanisms, such as the mass and radius of the resulting neutron star.
Using Spatial Curvature with H ii Galaxies and Cosmic Chronometers to Explore the Tension in H0

Published: August 2019

We present a model-independent measurement of spatial curvature Ω
k
in the Friedmann–Lemaître–Robertson–Walker universe, based on observations of the Hubble parameter H(z) using cosmic chronometers, and a Gaussian process (GP) reconstruction of the H ii galaxy Hubble diagram. We show that the imposition of spatial flatness (i.e., Ω
k
 = 0) easily distinguishes between the Hubble constant measured with Planck and that based on the local distance ladder. We find an optimized curvature parameter

when using the former (i.e.,

), and

for the latter (

). The quoted uncertainties are extracted by Monte Carlo sampling, taking into consideration the covariances between the function and its derivative reconstructed by GP. These data therefore reveal that the condition of spatial flatness favors the Planck measurement, while ruling out the locally inferred Hubble constant as a true measure of the large-scale cosmic expansion rate at a confidence level of ∼3σ.
The Birth of a Jet-driven Twin CME and Its Deflection from Remote Magnetic Fields

Published: August 2019

We report the formation of a complicated coronal mass ejection (CME) on 2015 August 23 by using the high temporal and high spatial resolution multi-wavelength observations taken by the Solar Dynamic Observatory and the Solar and Heliospheric Observatory. The CME exhibited both jetlike and bubble-like components simultaneously, and therefore, we call it a twin CME. Detailed imaging and kinematic analysis results indicate that the twin CME was evolved from the eruption of a mini-filament-driven blowout jet at the eastern edge of an equatorial coronal hole, in which the activation of the mini-filament was tightly associated with the continuous flux cancellation and quasi-periodic jetlike activities in the filament channel. Due to the magnetic reconnection between the filament and the ambient open field lines, the filament broke partially at the northern part and resulted in an intriguing blowout jet in the southern direction. It is interesting that the ejecting jet was deflected by a group of remote open field lines, which resulted in the significant direction change of the jet from southward to eastward. Based on the close temporal and spatial relationships among the jet, filament eruption, and the twin CME, we conclude that the jetlike CME should be the coronal extension of the jet plasma, while the bubble-like one should have originated from the eruption of the mini-filament confined by the closed magnetic fields at the jet base.
