The electronic properties of Carbon based nanomaterials have been attracted the attention of the scientific community for decades. The structural details of these systems are of fundamental importance to describing their properties. With the objective of offering a fundamental review that allows entry into research areas related to nanoscience, this work is dedicated to investigating the electronic properties of one-dimensional physical systems in a systematic and pedagogical way. We use a simple Tight - Binding model to obtain the band structure of these systems and describe their electronic behavior. At first, we describe the methodology used, demonstrating its simplicity for understanding introductory concepts in nanoscience. Then, we determine the energy band of a linear chain of atoms, considering only one site per unit cell. In order to offer an extrapolation of this system, we apply our model to Graphene and Boron Nitride nanoribbons, which can be interpreted as the interpenetration of linear chains, displaying N sites per unit cell. Finally, despite the simplicity of the proposed model, we demonstrate that the presented calculations show consistency with more robust formalisms, such as the DFT. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to promote an evaluation of the acceptance and use of the implanted technology (Electronic Information System) in a public institution in the state of Pernambuco, from the perspective of internal users of the system in the light of the Unified Theory of Acceptance and Use of Technology (Venkatesh, Morris, Davis & Davis, 2003). Methodology: A quantitative, analytical and descriptive approach with an exploratory objective was used. Data were collected using a structured form with statements grouped by constructs, elaborated and applied via google forms, using the Likert scale. The treatment of the collected data was carried out in two ways: i) descriptive statistics for the questions that deal with the demographic profile of the respondents, called moderating variables, according to the theory; and ii) the Average Ranking method was applied, confronting the aspects proposed in the theory for specific questions, verifying whether the notes of the sample responses correspond to the findings of the renowned author with respect to the relationship between constructs. Results: The results obtained point out that age, gender and experience directly influence the constructs. It is concluded, therefore, that there is a reasonable level of acceptance and use of CES. Although there is still resistance and conflicts to be faced in public management, most users see and understand positively that the system presented in the present study has been a relevant tool in public management, contributing to the management and control of information without leaving aside, support for decision-making, helping to improve the use of resources. Contributions of the study: The results contribute to the specific literature, because it presents results on acceptance and use in the public sphere, which can subsidize the process of implantation of the CES in other agencies, as well as for future research involving similar situations.

Landrace and Large White hybrid swine females were housed in collective pens during the gestation phase and submitted to different feeding systems. In one of the housing was used the manual feeding system, with feed provided directly on the floor. In the other, the electronic feeding system in a cage with free access Gestal 3G was installed. Two groups, composed of three matrices each, were separated by housing. The females were allocated according to their Body Condition Score (ECC) and birth order, seeking the homogeneity of the lots. The objective was to evaluate the variation of Body Weight (PC), ECC and Thickness of Bacon (ET) up to 107 days of gestation. For this purpose, CP and ECC measurements were performed every two weeks. ET was evaluated each 21 days. The data were submitted to descriptive and regression analysis over time. It was observed at the end of gestation that the group housed in the pens with an electronic feeding system showed less unevenness in relation to the PC and greater control of ECC. These results, added to the reduction of hierarchical disputes and for food competition, are important for maintaining the welfare of these females. Thus, automated feeding system proved to be important allies on the creation of pregnant swine matrices in collective pens. [ABSTRACT FROM AUTHOR]

Introduction: Considered an attribute of a more democratic, egalitarian and fair contemporary society, access to information is a constitutionally guaranteed right to every citizen. Objective: Thus, this study was carried out with professionals linked to the Electronic System of the Citizen Information Service (e-SIC), with the objective of knowing the profile of the manager of this service, as well as his/her satisfaction in relation to the performance of his/her professional duties in this work environment. Methodology: Regarding the methodological procedures, the research is characterized by its nature, predominantly qualitative of the descriptive type. The data were collected by means of questionnaires. Results: Among the objectives achieved in the survey, the profile of the professionals responsible for the management of e-SIC stands out: most of them are between 41 and 50 years old, are female, belong to different professions, such as lawyer and delegate, and work from one to two years in this work environment. Conclusion: It was also found that, despite the barriers encountered, the e-SIC managers perform their functions satisfactorily and consider the System as a power tool between society and the public sector, which enables more control and social communication and contributes significantly to the population.

This work sought to identify the existence and structure of participatory and democratic instances in the management of student assistance policy in Brazilian federal universities. To achieve this objective, requests for access to information were sent through the Electronic System of the Citizen Information Service -- the federal government's e-Sic Portal - to 63 universities in the federal education network, during the month of March 2020. From the contextualization of the student assistance policy in the Brazilian reality and from the perspective of democratic management, we analyze the strategies adopted by the institutions. Thus, we can affirm that there is student participation in the management of student assistance policy in most universities, although there is no formal guideline for the functioning of these mechanisms. The aim here is to stimulate the development of democratic management for this policy from the role of students, reiterating the need for organization and collective construction of these spaces.

To generate greater reliability and better accoutability, Decree 3,591 of 2000 obliged the institution of an internal audit unit in the organizational structure of public entities. This article aims to characterize the profile of internal audits of federal public universities in Brazil and thereby contribute with empirical material on the characteristics pointed out in the literature, given the lack of research addressing the theme. To this end, a survey was conducted, with a descriptive methodology and a qualitative approach to the data obtained from all 63 federal public universities existing in 2017, through the Electronic System of the Citizen Information Service (e-SIC). Of these, 62 had, by 2017, internal audit units in place and functioning. The results of the research showed that: the staff is composed of 335 servers, 97.61% of whom are tendered; 94.33% have higher education. In 68.85% of the audit units, they have up to six employees and 86.89% of the heads receive a bonus for management positions, due to their performance in advising management. There is no division into departments at 86.89% universities and 47.54% do not have enough servers. With this, it provides parameters and variables to be adopted in future research, aiming at a greater efficiency in the operation of this unit, considering that several norms are being issued providing theoretical and general guidelines for this purpose, and not considering the specific and structural aspects that interfere in the development of activities.

Na aplicação de produtos fitossanitários, a utilização de equipamentos que controlam automaticamente as seções da barra e a pulverização já é realidade; entretanto, ainda não há resultados que demonstrem a sua eficácia. Por esse motivo, este trabalho teve por finalidade desenvolver uma metodologia para a avaliação de um equipamento que controla automaticamente as seções e a pulverização. Avaliou-se um controlador automático de seções e pulverização de mercado, e, para tanto, foram utilizados três níveis de acurácia do sinal de GPS (algoritmo interno, SBAS e RTK), três ângulos para a simulação de entrada e saída da barra de pulverização em relação à borda do talhão (0; 45 e 60º ) e três velocidades de trabalho (1,66; 5,00 e 8,33 m s-1). A metodologia proposta possibilitou a determinação dos tempos e distâncias de abertura e fechamento das seções. Os coeficientes de variação para os tempos e distâncias de abertura e fechamento das seções indicaram uma variação considerável. Houve interações significativas em função do tipo de sinal de GPS. A configuração recomendada pelo fabricante e adotada para a avaliação do controlador automático de seções e pulverização não atende a todas as situações simuladas.In the application of pesticides, the use of equipment that automatically controls the sections of the boom and the spray is already reality. However, there are no results to show its effectiveness. Therefore, this work was to develop a methodology for the evaluation of equipments which automatically controls the boom sections and the spraying pattern. A commercial automatic controller of boom spraying sections was evaluated using three levels of GPS accuracy (internal algorithm, SBAS and RTK), three angles for the simulation of entry and exit of the spray bar on field edges (0, 45 and 60 º ) and three forward speeds (1.66, 5.00 and 8.33 m s-1). The proposed methodology allowed the determination of opening and closing times of the electric valves. The coefficients of variation indicated a considerable variation. There were significant interactions depending on the type of GPS signal used. The manufacturer recommended configuration, used for the evaluation of the automatic boom sections and spraying controller, does not attended all the simulated situations.

In the present article, one intends to present the Portuguese National Symbols through a legal and historical definition. One stresses the co-relation between Portuguese national identity, its symbols and the role of communication technologies in its formation, maintaining or changing. On one hand, symbols are understood as centripetal elements of cohesion reinforced by media. On the other hand, Portuguese National Symbols are presented as the result of an evolutionary process which can be identified with the History of Portugal, its leaders and the political power. To understand the feeling about the Portuguese National Symbols, one used an inquiry asking what the respondents (aged with less than 35 years old and inhabiting the district of Lisbon) thought about the Portuguese National Symbols and what would they change if they could. Finally, one complements her findings observing web petitions and personal websites where movements appealing to the Portuguese National Symbols change are presented. The results show the Portuguese attachment to their National Symbols and their agreement with its maintenance after the 25th April 1974 Revolution. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To compare the time required for generation and typing of radiology reports by means of an electronic system based on the technology of voice over internet protocol (VoIP) and the traditional system, in which the report is handwritten by the radiologist. MATERIALS AND METHODS: It was necessary to model, build and deploy the proposed electronic system, capable of recording the reports in a digital audio format and comparing it with the traditional method. Radiologists and transcriptionists recorded the reports generation and typing times for both systems, using appropriate forms. RESULTS: When the mean times between both systems were compared, those from the electronic system presented a reduction of 20% (p = 0.04 10) in the report generation time as compared with the traditional method. On the other hand, the traditional method was more efficient with respect to typing time, as the mean typing time with the electronic system was three times longer (p < 0.0001). CONCLUSION: The results demonstrated a statistically significant difference between the compared systems, with the electronic system being more efficient than the traditional one with respect to report generation time, while the traditional method presented better results with respect to typing time.

This paper approaches corpus linguistics as a subfield in applied informatics which features among its main focuses automatic data extraction from corpora. For this purpose, we develop commands and scripts in the UNIX bash command language, illustrating its applicability in the investigation of the -vel suffix and of iterations of letters and words in two of the main corpuses of Portuguese. We argue that using free software tools with textual interface, whose mastering together with programming skills is a necessity in computational linguistics, is more advantageous in corpus linguistics in comparison to commercial and proprietary programs with graphical interface.

The growing implementation of clinical information systems has led to several transformations within hospitals. However, scientific literature has revealed that most of these enterprises fall short of their main objectives. Thus, from an explanatory-exploratory case study, this article investigates the main causes of the unsuccessful implementation of an electronic prescription system in a general hospital, adopting as its theoretical background the resistance to information systems, as developed by Kling (1980) and Markus (1983). The study shows, for the case under analysis, that the main hurdles to deploying the system successfully were: the age of the medical doctors; excessive concerns with the safety of the system; inadequate technological infrastructure; the medical doctors' employment relationship; and the interference of the system with the power and autonomy of the medical doctors. The paper concludes that the hospital's intra-organizational context must be analyzed in a systemic way, in order to fully understand how the system will be accepted and used by its main potential users - the medical doctors.
