Aplicações de um potencial reativo no estudo da interação entre moléculas e superfícies bidimensionais

In materials science, the search for technological improvements have become one of the main subject of study of researchers. This is especially true in the case of materials with reduced sizes, in the nanometer scale. Important phenomena to be studied in these cases are the desorption and adsorption on two-dimensional materials, such as graphene. These phenomena are of great importance in the study of interactions between organic films, synthesis or catalysis of reactions on surfaces and even in the creation of nanoscale devices [1, 2, 3, 4]. Between the most important topics related to these phenomena are the storage of gases in low-dimensional systems and the study of nanostructured fuel cells or batteries. In this context we used two different parametrizations for the reactive force field ReaxFF to study the potential barriers and reaction barriers of our system. First we made a study about the Reaction Barriers and Energy Barriers for bonds between graphene and the following atoms: sulfur, fluorine, hydrogen, nitrogen and oxygen. It is important to have this information in order to make it possible to understand how these atoms react with the graphene sheet. Subsequently, we calculate reaction barriers for mixed structures where fluorine is a fixed element bonded to graphene and other element is simultaneously bonded to graphene. This other element (N, O, H or S) is varied in its possible relative positions (ortho, meta and para in relation to fluorine in either: the same side and in the opposite side of the graphene membrane)

Dimensão ética do gerenciamento em enfermagem

In managing an Inpatient unit, nurses face the need to make decisions involving agents in the institution’s internal and external environments, and all these measures are influential, regardless of how beneficial they may be. Hence, ethical issues constitute an important dimension of nursing management. This study aimed at identifying measures and/or interventions adopted by managing nurses at Inpatient Units in the Botucatu School of Medicine University Hospital - UNESP with the purpose to analyze professional ethics. The study involved nurses holding technicalsupervision positions in sectors related to the Nursing Division, comprising a total number of 20. The exploratory method was used by means of taped interviews with a qualitative approach based on the Collective Subject Discourse. Human resources deficit was observed as nurses’ major concern in relation to nursing care provision. The managers seek the nursing staff’s development by means of educational activities in their own unit at the same time that they adopt those offered by the hospital. When ethical violations occur, they resort to measures ranging from individual strategies for violators’ orientation to legal intervention. The resolution of ethical conflicts by nursing managers generally occurs in a gradual fashion by taking into account their compromising level, whether in relation to the patient or to the multiprofessional team. Educational activities are focused on the development of technical skills aiming at preventing physical damage to patients although educational activities targeted at the development of professionals’ ethical awareness were not mentioned

Comunicação organizacional e jornalismo: um estudo sobre as agências de comunicação de Bauru e a atuação jornalística

This monograph presents a study about organizational communication, outlining concepts, Brazilian historic, interfering factors and other considerations on the subject, introducing a survey with twelve communication agencies in Bauru as a result, explaining, in practical terms, how processes of organizational communication occur and the journalist's work in this area. Therefore, the organizational communication offers many possibilities for journalists, either as writers or press officers, or even in positions directly related to the Internet. As a key sector for all types of organizations, communication has gained notability, establishing itself as a strategic area for organizational management, especially in the form of integrated communication

Leitura crítica da produção literária de Alfonsina Storni

This paper presents the trajectory traced by the Literary Criticism on the poetry of Alfonsina Storni, an Argentine writer of the early twentieth century. The first literary production of Alfonsina Storni, called modernist or tardorromántica (SARLO, 1988), is produced in the period 1916-1925; from Ocre (1926), she marks a break, confirmed in their last two books of poetry, Mundo de siete Pozos (1935) and Mascarilla y Trébol (1938), with the label of vanguardism and new aesthetic experiences such as antisoneto. Regarding the Criticism built over the poetic work of Alfonsina Storni by his contemporaries, we have three positions of reading: approaches biographical criticism and proposals for readings of critics and poets linked to Vanguard Argentina and made some critical texts by women from the middle academic. According to Salomone (2006), the criticism made by third trend marks another landmark of the constitutive deed of Alfonsina Storni, show tensions and positions that differ from the hegemonic critical. Subsequently, there is setting up a Women's Literature, along with a normative critique, which will consider the production book produced by women as produced by a subject biological woman, and that represents certain textuality with naturalized features peculiar to women. Today, in light of the Critical Feminist and contributions of Discourse Analysis, especially on the concepts and the connections between language and power, a critical reading of the production female, consists of texts of women writers since the mid-nineteenth century, is focused as a result of an ideological perspective and typically androcentric patriarchal, for example, on poems by Alfonsina Storni. According to Alice Salomone (2006), from the 80s of last century, the look on the production literary Latin American writers has another approach, which she calls "critical current: feminist criticism and modernity cultural".

E.F. Perus Pirapora: personagens, posicionamentos e conflitos no processo de tombamento estadual (São Paulo/SP)

The process of recognition by the State of E. F. Perus Pirapora records the progress along many different interests and opinions, differences and conflicts unresolved even after the definition of recognition. Different opinions identified and their possible relationships with the subsequent abandonment of the property justify research efforts. Result of discussions over the development of a scientific research about industrial heritage, this article identifies people interested in this subject and conflicts presented in recognition 21.273/80. We understand this identification as possible subsidy for reflections about values, uses and management of the property recognized. Among the methods highlight the documentary research and interviews with the people involved in the recognition of the property. The process 21.273/80 was the focus of our investigation and it has been taken as official record of interests and positions of the people involved. The research concludes that conflicts between requestor and owner limited the effectiveness of the tool of recognition, resulting in abandonment and degradation of the heritage recognized. We also identify the positive presence of the government in this case represented by the Department of Culture of the State of São Paulo and CONDEPHAAT, on the management of the conflicts and the actions to safeguard the E.F. Perus Pirapora.

Evaluation of the cervical vertebrae maturation index in lateral cephalograms taken in different head positions

The aim of this study was to evaluate if upward or downward head inclination might interfere with determination of the growth stage, using cervical vertebrae maturation index (CVMI), in order to verify the accuracy of such diagnosis when radiographs are taken with errors. Forty-nine patients, 26 females and 23 males, aged 9 to 15 years, were submitted to 3 lateral cephalograms: normal (NHP), with 15° upward head inclination (NHP-Up), and with 15° downward head inclination (NHP-Down). Three examiners evaluated the CVMI on the 147 cephalograms. The agreement among examiners was higher in the evaluation of cephalograms taken in NHP. The weighted Kappa test revealed moderate to substantial agreement between NHP and NHP-Up and between NHP and NHP-Down. There was greater agreement between NHP-Up and NHP-Down. It may be concluded that the evaluation of the CVMI on cephalograms in NHP is different as compared with radiographs taken with inclinations. Both NHP-Up and NHP-Down exhibited greater disagreement in the interpretation among examiners, since the evaluation method was not designed for cephalograms with positioning errors.

Joint economic design of X̄ and R control charts for processes subject to two independent assignable causes

A model for the joint economic design of X̄ and R control charts is developed. This model assumes that the process is subject to two assignable causes. One assignable cause shifts the process mean; the other shifts the process variance. The occurrence of the assignable cause of one kind does not block the occurrence of the assignable cause of another kind. Consequently, a second process parameter can go out-of-control after the first process parameter has gone out-of-control. A numerical study of the cost surface to the model considered has revealed that it is convex, at least in the interest region.

Os fundamentos da Constituição Subjetiva segundo Laplanche

Article presents the concept of subjectivity in the theory of Jean Laplanche from his questioning of metapsychology´s drive theory which led to the proposal of the theory of generalized seduction. The objective is to show how in this conception otherness is presented in a traumatic way in the primary constitution of subjectivity, endorsing certain positions in the psychoanalytic literature that advocate symbolic violence as a fundamental aspect of the subject of psychoanalysis.

Recovery Plan for The Blue Whale (Balaenoptera musculus)

Recovery plans identify reasonable actions which are believed to be required to recover and/or protect endangered species. Plans are prepared by the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (FWS) and sometimes with the assistance of recovery teams, contractors, State agencies, and others. This plan was prepared by Randall R. Reeves, Phillip J. Clapham, Robert L. Brownell, Jr., and Gregory K. Silber for NMFS. Recovery plans do not necessarily represent the views nor the official positions or approvals of any individuals or agencies, other than those of NMFS, and they represent the views of NMFS only after they have been approved by the Assistant Administrator for Fisheries. Objectives will only be attained and funds expended contingent upon appropriations, priorities, and other budgetary constraints. Approved recovery plans are subject to modification as dictated by new findings, changes in species status, and the completion of recovery tasks described in the plan.
