Estudo de cerâmicas avançadas para fins de blindagem balística

The research involving new materials has always been considered as a differential in the development of a technology company. This occurred naturally since ancient times, often motivated by reasons of a certain age, where the most common material used was also the name of your time and may be cited as an example the Bronze Age, and later was the Iron. Currently, the use of firearms are they used in resolving conflicts between countries, or a more equivocal, as an instrument of social banditry make innovations in the area of shielding welcome, whether for personal use, in the form of vests or vehicle such as cars, tanks and even aircraft. In this context, is a Silicon Carbide Ceramic, with low density and high hardness. Thus, the aim of this study is the evaluation and comparison of these materials, seeking to improve their properties by means of additives such as boron and silicon metal and amorphous YAG. For this work, the specimens were pre-shaped by means of uniaxial later to be referred for isostatic pressing and sintering. The maximum percentage for each additive was 5%, except for the YAG whose percentage was 8.2% (mass percentage). All compositions were subjected to the same tests (x-ray diffraction, apparent density, optical microscopy, Vickers hardness, scanning electron Microscopita), so that one could draw a comparison between the materials under study, samples that showed better mechanical properties and micro structural, related here by hardness testing and microscopy (optical and SEM) were the silicon carbide doped with YAG and alumina samples, demonstrating the potential of these materials for ballistic protection. Other compositions have high porosity, which is highly undesirable, since in order to harmful influences on the mechanical properties discussed below

Multiculturalismo, diversidade cultural e cotidiano escolar: uma análise da temática em filmes de escola

This work has as its theme the multiculturalism, cultural diversity and their reflections in school everyday, more specifically on the interactions between the various subjects and social groups that make up a school and the teacher as mediator of the relationship between these guys. The theme Multiculturalism refers in the first instance, to the theoretical movement beginning in the mid-20th century in the United States and that spreads in the Western world as a way of tackling the conflicts generated depending on the economic issues, policies, and, in particular, cultural-ethnic, in an attempt to combat discrimination and prejudice, given the difficulties of individuals and groups to welcome and socialize with the plurality and cultural differences (SILVA; BRANDIM, 2008).At the same time, multiculturalism refers to cultural studies, through the Centre for Contemporary cultural studies, founded by em1964 Hoggart, and connected to the English language Department of the University of Birmingham in England.In contemporary times, due to the phenomenon of globalization and public policy to challenge prejudice and discrimination the subjects and social groups, regardless of color, creed, ethnicity, sexual orientation and nationality, this theme has been recurring in order to recognize plural identities and ensure and directly affects the school as a place of cultural diversity and conflicts generated by the very diversity.The present work aims to analyze and understand how the issue of multiculturalism and cultural diversity in school films. Our study will be based theoretically in Cultural Studies authors and uses the qualitative approach, working with movie content analysis of school, seeking to seize on the same relations of coexistence, conflicts and the mediations of teachers

Percepção de pacientes HIV-positivos de um centro de referência em relação a tratamento de saúde

Introduction: health professionals, in many cases, have defensive and exclusionary practices, patterns of prejudice and discrimination in response to HIVpositive patients. Objective: to verify the perception of patients seropositives from a reference center for STD/HIV/aids in relation to health care. Methods: there were interviews with questions related to discriminatory attitudes suffered, access and health care. Results: 130 individuals participated in the survey, from which 30 (23.1%) reported events of discrimination suffered outside the center of reference, predominantly from surgeon-dentists and 112 (86.2%) believed to have the same access and health care as other citizens. 62 (47.7%) treated with the dental center of reference, of which 56 (90.3%) felt good being treated in a dental unit only for HIV positive and six (9.7%) were indifferent, believed to be more exposed, or have a bias to attend dental seropositive individuals. Conclusion: it is concluded that many patients have already been discriminated against outside the reference center. However, most of them have a positive feeling towards the treatment received at a specifi c place for treating HIV-positive patients, due to the feeling of being welcome at that place due to the humanization and access to health care.

Characteristics, complexation and analytical methods of darunavir

What is it? Darunavir is a protease inhibitor used in the treatment of HIV infection. It is an important drug of therapy cocktail for patients infected with the virus. On the market there are darunavir ethanolate tablets of 75, 150, 300, 400, 600 and 800mg, because this is the most stable form. It is commercialized by Janssen-Cilag with the name PrezistaTM. Why we started? This drug has low water solubility and poor bioavailability, therefore requires administration in doses relatively high to the success of the therapeutic effect. The complexation of drugs by using cyclodextrin is welcome in this respect to improve the solubility and hence increase the dissolution rate of poorly soluble drugs. A monograph about this compound has not been described, thus it is an extremely important quality control of darunavir to demonstrate its effectiveness and safety. What we did? Some existing analytical techniques have been discussed in this manuscript, focusing on bioanalytical and pharmaceutical quality control applications. What we found? This review showed the published analytical methods reported for the determination of darunavir and discuss about its characteristics and complexation with cyclodextrin.

Dinner Prelude to the Nebraska Great Gardens Symposium

It’s a pleasure to welcome you to the University of Nebraska here in Lincoln. I’m delighted to be asked to join you for this dinner prelude to your Nebraska Great Gardens Symposium tomorrow. I’m also pleased to be able to welcome you to East Campus tonight, and to the Institute of Agriculture and Natural Resources, and I understand you’ll be meeting at the City Campus Union tomorrow. I am glad you have the opportunity to visit both campuses, and I hope you will come back when they are in bloom. As a newcomer to Nebraska myself – my wife Virginia and I arrived on a cold, snowy day last December, and I began my position here January 2 – I’m certainly looking forward to the arrival of spring. I have been told what a joy it is to be on this campus when plants and trees are in bloom, and when that special sense of spring renewal surrounds us.
