Undergraduate students' knowledge of copyright infringement
Authors: Tella Adeyinka , Oyeyemi Francis
Published: October 2019

This study examined undergraduate students’ knowledge of copyright infringement at the University of Ilorin, Nigeria. A descriptive survey design was adopted. Three hundred and seventy-two (372) undergraduate students randomly selected from twelve universities constituted the sample for the study. Four research questions were developed and answered and data was collected through a self-designed questionnaire. The findings demonstrate that the majority of the respondents are aware of copyright infringement and have strong perception that copyright infringement is a form of intellectual dishonesty. In addition, the results indicate that downloading content from the internet without permission from the owner is the major way through which undergraduates mostly infringed on the copyright. The findings also show that high cost of textbook is a contributing factor that leads students to infringe on copyright law, followed by scarcity of materials, fear of scoring poor marks, lack of awareness and overarching curricula while the desire to defy authority had the least influence. The increasing awareness of copyright law and possible punishment for violating the law was rated as the most fundamental way of reducing copyright infringement. The only hypothesis tested in the study revealed a significant difference in the perception of undergraduate students on copyright infringement based on their academic level with (Chi Cal. = 740.85, df=16, chi table= 26.30 at 0.05 level of significant difference). Upon these findings, the study recommends that author and publishers should try to reduce the cost of their textbooks. In addition, libraries in higher institutions should be well equipped with enough and relevant printed/literary resources. These should be readily available and accessible to the students when needed, in order to help reducing the rate of piracy and photocopying in higher institutions.
What about scientific collaboration in agriculture? a bibliometric study of publications about wheat and potato (1996-2016).
Authors: Cabrera Lilian , Talamini Edson , Dewes Homero
Published: October 2019

In evolutionary biology, the ability to cooperate may have determined the success of the human race over other races. In agriculture, it seems to be the key to increasing agricultural productivity to feed nine billion people. Thinking about it, the main scope of this work is to measure the cooperation - scientific collaboration - through the co-authorships analysis in the agriculture field of literature. The goal was to map the countries that collaborate scientifically in the food security area. We considered articles published in the last 20 years in Web of Science and the results were analyzed using the VOSviewer software. The results indicate that the gene (the term "gene") was the predominant theme in the density of the terms in the articles and also in the studied subjects. The United States is the country that most contributes, followed by China. These two countries also have the largest mutual collaboration, with 254 connections between them.

O texto aborda uma perspectiva histórica e crítico-conceitual do campo informacional, através da reflexão de Rafael Capurro. O objetivo está em compreender o desenho das cartografias epistemológico-históricas da Ciência da Informação refletidas nas duas fases do pen-samento capurriano, demarcadas entre os anos 1990 e 2000. Em dois momentos distintos, via duas descrições teóricas, o epistemólogo procura reconhecer modos de classificar, em termos de uma teoria do conhecimento como pano de fundo, o percurso metateórico do campo informacional. Por meio do uso de uma noção não-kuhniana de paradigma, o que pode resultar em análises precipitadas de seu pensamento, o epistemólogo nos apresenta duas possibilidades distintas e relacionais de compreensão do campo, uma de fundo filosófi-co-extemporânea, outra de fundo epistemológico-fronteiriça. O resultado da compreensão dos discursos de Capurro demonstra as inter-faces e as especificidades de cada cartografia epistemológico-histórica, bem como as consequências de uma perspectiva filosófica de fundo epistemológico. A carta filosófica aponta para a direção de uma tradição linguístico-pragmática que fundamenta a Ciência da In-formação. A carta epistemológica resulta na fronteira de um dado espaço-tempo de fundo crítico-linguístico-social. Eis as cartas que são como duas páginas da mesma folha cartográfica da informação: a folha do mapa angelicó de Capurro.
Um retrato da produção científica brasileira baseado em dados da plataforma LATTES
Authors: Dias Thiago Magela Rodrigues , Moita Gray Farias
Published: October 2019

Os estudos sobre dados de produções científicas têm recebido atenção de pesquisadores, de diversas áreas, que visam obter conhecimento sobre a evolução das pesquisas em geral. Tais estudos possibilitam a análise da produção científica para diversos propósitos e um dos desafios neste tipo de análise está na diversidade de repositórios contendo dados em formatos e estruturas distintas. Além disso, problemas como redundância dos dados, ambiguidade e dados incorretos tornam as análises ainda mais complexas. Neste artigo, é realizada uma análise dos dados curriculares de pesquisadores brasileiros cadastrados na Plataforma Lattes. A quantidade de dados analisados possibilita obter uma visão de todo o conjunto que é composto por milhões de currículos, e que contém dados sobre publicações científicas, nível de formação, áreas de atuação, dentre outros. Nos resultados apresentados, é possível obter uma visão sobre a produção científica brasileira e qual o perfil da produtividade dos doutores que tem atuado no Brasil.
Tesauros e ontologias como modelos de sistemas de organização do conhecimento
Authors: Moreira Walter
Published: October 2019

Discute os conceitos de organização e representação do conhecimento como subsídios para a compreensão dos tesauros e das ontologias enquanto modalidades de sistemas de organização do conhecimento. A análise das relações de complementaridade entre ambos os instrumentos faz-se necessária para reafirmar a concepção de que o aspecto tecnológico e, principalmente, categorial mais os aproxima do que os isola. Subordinando, portanto, os conceitos de tesauro e de ontologias ao conceito mais amplo de sistemas de organização do conhecimento, reflete sobre algumas de suas implicações teóricas e aplicadas. Tais reflexões são orientadas pelo modo como cada instrumento compreende as relações conceituais associativas. Conclui-se que o aparato tecnológico que se utiliza para a caracterização dos conceitos e de suas relações nas ontologias contribui para a construção de tesauros mais sofisticados do ponto de vista da explicitação dos conceitos e das relações conceituais que visa estabelecer. Em outra direção e de modo complementar, o modelo de análise categorial e facetado empregado na construção de tesauros também contribui para a construção de ontologias semântica e estruturalmente mais densas.

Partindo-se do uso da abordagem sistêmica, realizou-se uma discussão sobre a questão da gestão com pessoas, com vistas à construção de conhecimento em ambientes organizacionais. Para tanto, num primeiro momento, são detalhados elementos da abordagem sistêmica; na sequência, abordam-se questões da gestão com pessoas que poderiam redundar na construção do conhecimento em ambientes organizacionais, dando-se ênfase ao comportamento informacional. A presente pesquisa enfoca o âmbito das empresas de Tecnologia da Informação que se dedicam ao desenvolvimento de softwares, salientando sua caracterização enquanto sistemas sociotécnicos complexos. Salienta-se também a complexidade envolvida nos projetos de software e as inter-relações entre programadores em suas equipes, clientes e stakeholders, estrutura organizacional e aspectos da Engenharia de Software. Consideram-se os fluxos informacionais tanto formais quanto informais, como sendo o elemento agregador dos distintos componentes do sistema sociotecnico, que permite a eficácia na realização do trabalho. Portanto, foi efetuado um estudo de casos múltiplos em duas organizações de desenvolvimento de software para verificar a consistência dos fluxos informacionais, referentes ao compartilhamento da informação e sua formalização, especificamente. A abordagem utilizada foi a quantitativa, aplicando-se questionários com escala de Likert para os colaboradores das empresas, que foram analisados mediante a estatística descritiva. Apurou-se, desta forma, a necessidade de equilibrar os fluxos informacionais, principalmente melhorando o aspecto do registro ou documentação de informações. Por fim, são feitas as considerações finais, com o intuito de se busca inter-relacionar os elementos abordados no estudo.

ENSAIO SOBRE A UNIDADE SINTÉTICA MERAMENTE SENSÍVEL
Authors: CALABRIA Olavo
Published: October 2019

I present the essay of my critique to the interpretation that the synthetic unity of intuition in Kant can only result from the effective participation of intellectual faculties. For this, I maintain that the objects of intuition are constructed not only by means of the understanding (lato sensu), but also by the simple imagination, by means of a synthetic unit of the multiple of the intuition given to the sense, without it being necessary the direction or conduction of discursive units, but respecting only autochthonous rules. Thus these objects of intuition contain a unity originated only from the sensibility (merely sensible synthetic unit), for they are produced only by the imagination, under the only condition of obtaining the disconnected manifold of sensible representations from the collaboration of the senses. The faculty of imagination is apt to produce these conceptually indeterminate objects of the empirical intuition called “appearances” [Erscheinungen], because it is a spontaneous sensible capacity with duplicity of character, impulses and aptitudes (Calabria: 2012, 115-167, 2015 and 2016). In addition to showing that appearances, while blind intuitions containing a subjective unity, nevertheless provide an objective reference to empirical intuitions (as mind modifications), I explain in what sense Kant considers appearances to be transformed into objects of experience called «phenomena» [Phaenomena], when they receive the intellectual unit from the application of conceptual representations.

«KANT-STUDIEN» NOVALIS

Published: October 2019

O presente contributo oferece a versão em língua portuguesa de um conjunto de anotações coligidas por Novalis em 1797, postumamente intitulado “Kant-Studien”: um escrito que, assim o pretende demonstrar também a apresentação da peça, prova que para além de poeta, Novalis era também um atento leitor de Kant, e de Reinhold e Fichte; e que, se até certo ponto Novalis é defensor dos pressupostos gerais da filosofia crítica de Kant, por outro, ele diverge da mesma, e a partir dela constrói a sua própria posição sobre o problema – uma posição que, advogando a impossibilidade de um princípio supremo da filosofia, reuniria em seu torno Hölderlin, F. K. Forberg, I. Niethammer ou J. B. Erhard.
Autonomia e liberdade: uma fundamentação kantiana para direitos humanos segundo Caranti

O livro de Caranti Kant’s Political Legacy: Human Rights, Peace, Progress é instigante, não só por tentar avançar a argumentação kantiana, como pelas acuradas interpretações do próprio Kant. Deveras, o legado de Kant é disputado pelas mais diferentes correntes da filosofia, sendo que Caranti se posiciona bem em tal disputa.
Uma fundamentação kantiana dos direitos humanos?
Authors: Pinzani Alessandro
Published: October 2019

O novo livro de Luigi Caranti (2017) representa uma tentativa não de atualizar Kant, mas de servir-se da sua filosofia política e jurídica como de um ponto de partida para desenvolver posições normativas que podem ser denominadas kantianas no sentido de serem inspiradas por Kant, embora não espelhem exatamente suas visões sobre os assuntos discutidos no livro, a saber: os direitos humanos, as relações internacionais e a história. Nesta minha intervenção me concentrarei em um aspecto do livro de Caranti, a saber, sua afirmação de que é possível construir uma teoria dos direitos humanos a partir das escassas observações feitas por Kant sobre o assunto na Doutrina do Direito. Não discutirei neste contexto a leitura que Caranti faz da teoria kantiana das relações internacionais, que já estava no centro do seu livro La pace fraintesa (2015). Da mesma maneira, não discutirei, por falta de espaço, a sua leitura da filosofia kantiana da história.
Reply to my critics
Authors: Caranti Luigi
Published: October 2019

In this essay I reply to the very interesting comments about my book Kant’s Political Legacy. Human Rights, Peace, Progress (University of Wales Press 2017) offered by the following Kant scholars: Alessandro Pinzani, Cristina Foroni Consani, Milene Consenso Tonetto, Delamar José Vulpato Dutra, Robinson dos Santos, Andrea Faggion, Aylton Barbieri and Joel Thiago Klein. A theme on which my critics commonly insist is the compatibility between Kant’s theory of right (in particular some of the rights and duties spelt out in the Rechtslehre) and the values central in the culture human rights. Another one is whether it makes sense to use an essentially moral concept, such as that of dignity, for the foundation of human rights, given that they are usually conceived of as juridical or proto-juridical rights. In general all commentators raise informed and well documented points that deserve keen attention.

Liberdade Transcendental – Liberdade Empírica / Psicológica
Authors: Faggion Andrea

Liberdade é o conceito mais importante da filosofia de Immanuel Kant. Já liberdade transcendental é um dos conceitos mais obscuros da história da filosofia. Este trabalho tenta jogar alguma luz sobre esse conceito e seu par: liberdade empírica/psicológica.
Conhecimento histórico e conhecimento racional
Authors: Seneda Marcos César
Published: October 2019

Conquanto seja utilizada somente no terceiro capítulo da Doutrina Transcendental do Método, designado “A arquitetônica da razão pura”, a distinção entre conhecimento histórico e conhecimento racional é um topos básico das Lógicas de Kant, marcando a diacronia de suas reflexões metafísicas. No percurso aqui proposto para esclarecer essas duas noções, remontamos a Christian Wolff. Para situar a posição epistemológica da Filosofia, no Discurso preliminar sobre a filosofia em geral, Wolff explicita a diferença entre os conhecimentos histórico, filosófico e matemático, na tentativa de alocar toda a aquisição do nosso conhecimento no interior dessa tripartição. Kant acolhe essa divisão tripartite, mas vai reduzi-la à oposição entre conhecimento histórico e conhecimento racional, equacionando o conhecimento empírico com o histórico, e situando filosofia e matemática no interior do último modo de conhecimento. Procurou-se aqui mostrar que essas duas noções decisivas e contrapostas são conversíveis entre si, articulando-se no interior daquilo que Kant denomina uma arquitetônica. Mediante essa distinção, Kant procura um princípio metodológico de unificação, opondo as noções de agregação e subordinação, que darão origem às noções de agregado e sistema. Sendo ciência sistemática, a filosofia é projetada no vértice da disposição racional de todas as ciências, guardando consigo a responsabilidade de abrigar a meta final de todo o uso da razão humana.
Forma

Published: October 2019

Apresentação do conceito de forma, ao qual se aplica o adjetivo de conformidade a fim no juízo de gosto. Trata-se de mostrar como Kant concebe a forma dos objetos belos na terceira Crítica, indo desde uma definição genérica e ampla como síntese do múltiplo do fenômeno até a especificação tomada como formalista pela tradição de comentários, ou seja, baseada quase exclusivamente nas relações espaço-temporais.
Gênio

Published: October 2019

Apresentação da noção kantiana do gênio, assumindo-a como ato inaugural da concepção romântica e moderna de criação artística. Ao longo da modernidade, na contramão do sentido dado por Kant ao gesto criador, a ideia de gênio foi se transformando em mera inspiração subjetiva. O intuito deste verbete é de procurar recuperar o sentido kantiano de criação na arte de modo a torna-lo mais pertinente para o debate estético contemporâneo.
Estilo

Published: October 2019

O verbete visa a elucidar os distintos modos pelos quais Kant apresenta o conceito de estilo. Concebido como modo de expressão dos pensamentos associado à linguagem, à eloquência e às condições subjetivas da comunicação, o conceito de estilo também aparecerá vinculado aos temas do gênio artístico e à simplicidade no sentimento do sublime.

The diversity in the types of vegetation, Brazil is the second largest biome Cerrado, occupying 25% of the country, surpassed only by the Amazon. In Minas Gerais, the Brazilian state has about 10.3% of its area the Cerrado vegetation, covering mainly areas of the Upper and Middle Jequitinhonha. The flora of the cerrado has several fruit species with high potential for agricultural use, which are traditionally used by local people, and the fruits have high levels of sugars, proteins and minerals. Among the great diversity of plants and fruits present in the cerrado is the Eugenia dysenterica, popularly known as cagaita. The fruit is globular yellow color when ripe, slightly acid and can reach up to 4 cm long and up to 5 cm diameter. The work here exposed was led initially to a survey of state schools that have high school in the city of Sete Lagoas-MG. After this survey was chosen for the project development a nearby school of the Federal University of Sao Joao del Rei (UFSJ-CSL) for viability of the project and in which direction proved to be very available. 3rd year high school classes were chosen, totaling 55 students, selecting the students who had greater knowledge of the concepts studied and shown interest. Various activities with students have been developed, one of which is the application of a questionnaire in the first meeting, which enabled us to identify where the problems thereof. a booklet with texts followed fixation exercises and illustrative images on each topic worked in class and the students images developing the proposed project activities was developed. This study aimed to use a fruit of the Cerrado, cagaita to perform fermentation and subsequent distillation, to promote ownership of the concepts of chemistry, biochemistry and biotechnology in high school students. Through the questionnaire at the end of the project, it was possible to assess the relevance of their work and the impact on the training of students. The study proved to be very promising for the students and the school, where probably, future students of the University. It is important to emphasize that the development of the project was very promising because it allowed greater interaction of students with dynamic classes, practical and contextualized, allowing a greater learning of them.

Published: October 2019

This study aimed to know the profile of the hypertensive population, using drug therapy, not responsive to antihypertensive treatment. We interviewed 37 people diagnosed with systemic arterial hypertension even when they were treated. Patient data were collected through a questionnaire to assess the profile of people who have high blood pressure, even using antihypertensive. The results showed that the most common causes were sedentary lifestyle (35.1%), alcohol use, smoking and forgetfulness of medication use (29.7%). When analyzing the questionnaire, the participants' low schooling was diagnosed, since 56.7% were literate, 41.5% had elementary education, and 51.3% received less than a minimum wage. In conclusion, this study suggests the main influencing factors for the non-control of systemic arterial pressure, allowing to elaborate better strategies to combat systemic arterial hypertension

Published: October 2019

Tracheobronchial secretion was collected by endoscopy (Welch-AllynÒ, 200cm long and 9mm diameter), from equines with different ages, races and sex, for posterior cytological analysis. Thirty-six equines were divided into two groups (Group I = stabled, n = 18; Group II = field regimen, n = 18). Animals of Group I (age = 3.5 years) were lodged in the Tarumã´s Jockey Club in Curitiba, Parana State. The equines of Group II always were maintained at field condition (never were stabled), in the farm located in Jacarezinho, Paraná State. Following endoscopic exams, tracheobronchial secretion smears were stained by Pappenhein´s method and submitted to cytological analysis. Group I had higher frequency of tracheal discharge than Group II. The cytological analysis showed more presence of macrophages (58.8%), foamy cells (2.3%), body giant cells (0.2%), neutrophils (4.57%), eosinophils (0.7%) and Curshmann´s spirals (0.04%) on 3 of the 18 animals. The cytological analysis of Group II showed higher frequency of ciliated epithelial cells than Group I, and no Curshmann´s spirals were observed. In conclusion, data showed that horses stabled had more cytological alterations than the animals maintained at field, therefore more tracheobronchial complications. Thus, the care of place where horse are stabled have influence on development of respiratory diseases, may predispose to affections as Chronic Obstructive Pulmonary Disease and Exercise-Induced Pulmonary Hemorrhage, as well athletic horses may be never reach their full respiratory potential.

An Exploration into Gender-related Differences in Pronunciation among Libyan Learners of English as a Foreign Language
Authors: Es-skare Hawa , Aburawi Mariem , Shenina Khalifa ,   Misurata University,   Misurata University,   Misurata University
Published: October 2019

This research paper mainly discussed the gender-related differences from the aspects of pronunciation, mainly intonation and stress, among Libyan students who learn English as a foreign language. The researchers have randomly selected twenty undergraduate students from the third and fourth semesters (ten female students and ten male students) from the English department, Faculty of Arts, Misurata University to participate in the research and asked to read aloud several written sentences. Their actual pronunciation was recorded and analyzed using a quantitative approach to find out if there were significant differences among female and male participants' pronunciation. The research results revealed that there were not considerable differences between female and male participants' pronunciation. Both groups have had some difficulties in recognition of the correct intonation pattern and putting the stress on the right words. Moreover, female students generally outperformed male ones, though; male participants were slightly better than female ones in identifying the accurate stressed words. Finally, it was suggested that individual differences among learners, including gender-related differences, play an important role in enhancing language teaching and learning process.
Difficulties in Teaching English Language to Grade Nine at the Fundamental Stage in Misurata City
Authors: Albukbak Omar
Published: October 2019

This research paper attempts to identify some problems and difficulties that impact the teaching of English language in grade nine in four fundamental stage schools in Misurata city. The study tries to explore what barriers and obstacles learners and teachers might face in the learning-teaching process. The research methodology underlying this research paper is a questionnaire. The questionnaire is administered to three sample groups: teachers, students, and inspectors of English. The presentation of the results of the questionnaire showed an illustration of several difficulties and problems that are encountered in the process of teaching English as a foreign language in the fundamental stage. These problems in brief are: the high number of students in class, the lack of qualified English teachers who could teach the syllabus appropriately, some teachers do not follow the instructions available in the teacher's book, the interference of the Arabic language on the English language, the students’ feeling when asked to speak in English, pronouncing some English sounds, and learning the English writing system. The results and discussion of the study suggest how to overcome these difficulties and problems by following the modern teaching strategies and approaches and their implications in classrooms.
Damage characteristic of aluminum nanorod under hypervelocity impact
Authors: Wu Yong-Chao , Shao Jian-Li , Zhan Haifei
Published: October 2019

Understanding the dynamic behavior of materials under hypervelocity impact is of great importance to develop new materials or structures for protective applications. The present work gives insight into the damage characteristic of aluminum nanorod under hypervelocity impact based on atomistic simulations. First of all, the propagation of impact wave is found to experience a rapid decaying because of its release from the side surface, which leads to a complex three-dimensional stress wave and two tension regions inside the nanorod. The damage mode under this tension state is found to be very different from the classical spallation. Due to the interaction of two release waves from the side and end surfaces, a temporary spall damage is observed and its initial tensile strength is close to that of bulk material. However, that early spall damage does not develop into a complete spall fracture. More importantly, all generated voids are found to be closed eventually after their coalescence. Furthermore, the mass continues expanding outward from the impact plane and finally causes a radial annular fragmentation. The annular fragmentation shows a clear crystalline direction dependence for low impact velocities. The number and the size of final fragments are found to follow a power law relationship for all impact velocities.

The present work explores the ability of poly (1-vinyl imidazole) to complex si-RNA against vascular endothelial growth factor (VEGF) and its in vitro efficiency in A549 lung cancer cells. The polyplex formed was found to exhibit 66% complexation efficiency. The complexation was confirmed by gel retardation assay, FTIR and thermal analysis. The blank PVI polymer was not toxic to cells. The polyplex was found to exhibit excellent internalization and escaped the endosome effectively. The polyplex was more effective than the free si-RNA in silencing VEGF in lung cancer cells. The silencing of VEGF was quantified using Western blot which was also reflected in depletion of HIF-1a levels in the cells treated with the polyplex. VEGF silencing by the polyplex was found to augment the cytotoxic effects of the chemotherapeutic agent 5-fluorouracil. Microarray analysis of the mRNA isolated from cells treated with free siRNA and polyplex reveal that the superior VEGF silencing by the polyplex altered the expression levels of several other genes that have been implicated in the proliferation and invasion of lung cancer cells. These results indicate that PVI complexed anti-VEGF can be an effective strategy to counter lung cancer.

We obtained radio observations of the symbiotic binary and known recurrent nova T Coronae Borealis following a period of increased activity in the optical and X-ray bands. A comparison of our observations with those made prior to 2015 indicates that the system is in a state of higher emission in the radio as well. The spectral energy distributions are consistent with optically thick thermal bremsstrahlung emission from a photoionized source. Our observations indicate that the system was in a state of increased ionization in the companion wind, possibly driven by an increase in accretion rate, with the radio photosphere located well outside the binary system.
Runaway Young Stars near the Orion Nebula
Authors: McBride Aidan , Kounkel Marina
Published: October 2019

The star-forming region of the Orion Nebula (ONC) is ideal to study the stellar dynamics of young stars in a clustered environment. Using Gaia DR2 we search for pre-main sequence stars with unusually high proper motions that may be representative of a dynamical ejection from unstable young triple systems or other close three-body encounters. We identify 26 candidate stars that are likely to have had such an encounter in the last 1 Myr. Nine of these stars could be traced back to the densest central-most region of the ONC, the Trapezium, while five others have likely interactions with other OB-type stars in the cluster. Seven stars originate from other nearby populations within the Orion Complex that coincidentally scattered toward the ONC. A definitive point of origin cannot be identified for the remaining sources. These observations shed light on the frequency of the ejection events in young clusters.
Photoelectron Sheath on Lunar Sunlit Regolith and Dust Levitation
Authors: Mishra S. K. , Bhardwaj A.
Published: October 2019

Photoelectron sheath formation and subsequent fine dust levitation over the sunlit lunar regolith have been investigated by consistently accounting for the continuous interaction of the solar wind and solar radiation with the Moon. In deriving the photoelectron sheath, the Poisson equation is coupled with the latitude-dependent population density of the Fermionic photoelectrons. The altitude and latitude profiles of the electric potential, electric field, and electron density within the photoelectron sheath have been derived. A larger sheath is predicted near the terminator compared to the subsolar point. Accounting for the sheath features, the charging of levitating particles under the kinetic balance of anisotropic photoelectron flux, solar radiation, and solar wind plasma has been calculated. The dust charge is coupled with a characteristic sheath field to evaluate the altitude profile of the particle size, displaying levitation under its electrostatic equilibrium with the lunar gravity. Our analysis suggests that in equilibrium, the submicron particles may levitate up to a couple of meters above the lunar surface; for instance, at the subsolar point (0° latitude) 200 and 50 nm particles may float up to an altitude of ∼64 and ∼194 cm, respectively, while at 70° latitude near the terminator these particles are estimated to levitate at an altitude of ∼18 and ∼227 cm, respectively. The floating charged submicron dust may electrostatically interact with the functioning of experiments and can significantly affect the instrument operation.

We present a source catalog from the first deep hard X-ray (E > 10 keV) survey of the Small Magellanic Cloud (SMC), the Nuclear Spectroscopic Telescope Array (NuSTAR) Legacy Survey of the SMC. We observed three fields, for a total exposure time of 1 Ms, along the bar of this nearby star-forming galaxy. Fields were chosen for their young stellar and accreting binary populations. We detected 10 sources above a 3σ significance level (4–25 keV) and obtained upper limits on an additional 40 sources. We reached a 3σ limiting luminosity in the 4–25 keV band of ∼1035 erg s−1, allowing us to probe fainter X-ray binary (XRB) populations than has been possible with other extragalactic NuSTAR surveys. We used hard X-ray colors and luminosities to constrain the compact-object type, exploiting the spectral differences between accreting black holes and neutron stars at E > 10 keV. Several of our sources demonstrate variability consistent with previously observed behavior. We confirmed pulsations for seven pulsars in our 3σ sample. We present the first detection of pulsations from a Be-XRB, SXP 305 (CXO J005215.4–73191), with an X-ray pulse period of 305.69 ± 0.16 s and a likely orbital period of ∼1160–1180 days. Bright sources (≳5 × 1036 erg s−1) in our sample have compact-object classifications consistent with their previously reported types in the literature. Lower-luminosity sources (≲5 × 1036 erg s−1) have X-ray colors and luminosities consistent with multiple classifications. We raise questions about possible spectral differences at low luminosity between SMC pulsars and the Galactic pulsars used to create the diagnostic diagrams.

Measurements of 21 cm Epoch of Reionization (EoR) structure are subject to systematics originating from both the analysis and the observation conditions. Using 2013 data from the Murchison Widefield Array (MWA), we show the importance of mitigating both sources of contamination. A direct comparison between results from Beardsley et al. and our updated analysis demonstrates new precision techniques, lowering analysis systematics by a factor of 2.8 in power. We then further lower systematics by excising observations contaminated by ultra-faint RFI, reducing by an additional factor of 3.8 in power for the zenith pointing. With this enhanced analysis precision and newly developed RFI mitigation, we calculate a noise-dominated upper limit on the EoR structure of Δ2 ≤ 3.9 × 103 mK2 at k = 0.20 h Mpc−1 and z = 7 using 21 hr of data, improving previous MWA limits by almost an order of magnitude.

This paper presents the result of Hα imaging for luminous and ultraluminous infrared galaxies. It is a complete subsample of the Great Observatories All-sky LIRG Survey (GOALS) with decl. ≥ −30°, and consists of 148 galaxies with log(L
IR/L
☉) ≥ 11.0. All the Hα images were carried out using the 2.16 m telescope at the Xinglong Station of the National Astronomy Observatories, Chinese Academy of Sciences (NAOC), during the year from 2006 to 2009. We obtained the pure Hα luminosity for each galaxy and corrected the luminosity for [N ii] emission, filter transmission, and extinction. We also classified these galaxies based on their morphology and interaction. We found that the distribution of star-forming regions in these galaxies is related to this classification. As the merging process advanced, these galaxies tended to have a more compact distribution of star-forming regions, higher L
IR, and warmer IR-color (f
60/f
100). These results imply that the degree of dynamical disturbance plays an important role in determining the distribution of a star-forming region.
The Carnegie-Irvine Galaxy Survey. VIII. Demographics of Bulges along the Hubble Sequence

Published: October 2019

We present multicomponent decomposition of high-quality R-band images of 320 disk galaxies from the Carnegie-Irvine Galaxy Survey. In addition to bulges and disks, we successfully model nuclei, bars, disk breaks, nuclear/inner lenses, and inner rings. Our modeling strategy treats nuclear rings and nuclear bars as part of the bulge component, while other features such as spiral arms, outer lenses, and outer rings are omitted from the fits because they are not crucial for accurate bulge measurements. The error budget of bulge parameters includes the uncertainties from sky-level measurements and model assumptions. Comparison with multicomponent decomposition from the Spitzer Survey of Stellar Structure in Galaxies reveals broad agreement for the majority of the overlapping galaxies, but for a considerable fraction of galaxies there are significant differences in bulge parameters caused by different strategies in model construction. We confirm that on average bulge prominence decreases from early- to late-type disk galaxies, although the large scatter of bulge-to-total ratios in each morphological bin limits the application of Hubble type as an accurate predictor of bulge-to-total ratio. In contrast with previous studies claiming that barred galaxies host weaker bulges, we find that barred and unbarred spiral galaxies have similar bulge prominence.
