Gestão do Conhecimento aplicada à redes de Fast-Food

The knowledge currently stands as one of the intangible assets of fundamental importance in the competitive market in which it is organizations. Knowledge management has become mandatory in the competitive environment of today, as a tool to systematize knowledge within the organization. Underscoring the importance of this management process, this thesis aimed to identify possible problems and generate recommendations for improving the performance of Knowledge Management. The objective was achieved by conducting the analysis of a case study of a fast-food franchise through a case study in the ground plan of all the franchise restaurants. For the preparation of the case study was required to respect a theoretical review on the introduction of the concepts of knowledge management in fast-food restaurants, in addition to reviewing the theory on the concepts of organizational learning and on Standardization. When finalizing the theoretical review and analyze the case study was proposed recommendations and highlight difficulties and good practice found in the analyzed organization, and procedures for demonstrating the success of knowledge management in organizations

Fast determination of beef quality parameters with time-domain nuclear magnetic resonance spectroscopy and chemometrics

The noteworthy of this study is to predict seven quality parameters for beef samples using time-domain nuclear magnetic resonance (TD-NMR) relaxometry data and multivariate models. Samples from 61 Bonsmara heifers were separated into five groups based on genetic (breeding composition) and feed system (grain and grass feed). Seven sample parameters were analyzed by reference methods; among them, three sensorial parameters, flavor, juiciness and tenderness and four physicochemical parameters, cooking loss, fat and moisture content and instrumental tenderness using Warner Bratzler shear force (WBSF). The raw beef samples of the same animals were analyzed by TD-NMR relaxometry using Carr-Purcell-Meiboom-Gill (CPMG) and Continuous Wave-Free Precession (CWFP) sequences. Regression models computed by partial least squares (PLS) chemometric technique using CPMG and CWFP data and the results of the classical analysis were constructed. The results allowed for the prediction of aforementioned seven properties. The predictive ability of the method was evaluated using the root mean square error (RMSE) for the calibration (RMSEC) and validation (RMSEP) data sets. The reference and predicted values showed no significant differences at a 95% confidence level.

Development of biomimetic sensor for fast and sensitive detection of Norfloxacin

A biomimetic sensor is proposed as a promising new analytical method for determination of norfloxacin (NF) in pharmaceuticals. The sensor was prepared by modifying a glassy carbon electrode surface with a Nafion® membrane doped with poly(copper phthalocyanine) complex [poly-CuPc]. Amperometric measurements carried out with the sensor under an applied potential of -0.05 V vs Ag|AgCl in 0.1 mol L-1 acetic acid containing 1.5 × 10-3 mol L-1 hydrogen peroxide showed a linear response range from 2.0 × 10-4 to 1.2 × 10-3 mol L-1. Selectivity and interference studies were also performed. A sensor response mechanism is proposed, based on the experimental evidence. Recovery studies were carried out using environmental samples, in order to evaluate the sensor’s potential for use with these sample classes. Finally, sensor performance was evaluated using analyses of commercial formulations.

Luminescence properties of Eu-complex formations into ordered mesoporous silica particles obtained by the spray pyrolysis process

Ordered mesoporous, highly luminescent SiO2 particles have been synthesized by spray pyrolysis from solutions containing tetraethylorthosilicate (TEOS), Eu(NO3)3.6H2O, and cetyltrimethylammonium bromide (CTAB) as structure-directing agents. The 1,10-phenantroline (Phen) molecules were coordinated in a post-synthesis step by a simple wet impregnation method. In addition, other matrices were also prepared by the encapsulation of europium complex Eu(fod)3 (where fod = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionato) into mesoporous silica, and then the Phen molecules were encapsulated by different impregnation steps, after which the luminescence properties were investigated. The obtained materials were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder x-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. Powders with polydisperse spherical grains were obtained, displaying an ordered hexagonal array of mesochannels. Luminescence results revealed that Phen molecules had been successfully coordinated as an additional ligand in the Eu(fod)3 complex into the channels of the mesoporous particles without disrupting the structure.

Bio-hydrogen production based on catalytic reforming of volatiles generated by cellulose pyrolysis: an integrated process for ZnO reduction and zinc nanostructures fabrication

The paper presents a process of cellulose thermal degradation with bio-hydrogen generation and zinc nanostructures synthesis. Production of zinc nanowires and zinc nanoflowers was performed by a novel processes based on cellulose pyrolysis, volatiles reforming and direct reduction of ZnO. The bio-hydrogen generated in situ promoted the ZnO reduction with Zn nanostructures formation by vapor–solid (VS) route. The cellulose and cellulose/ZnO samples were characterized by thermal analyses (TG/DTG/DTA) and the gases evolved were analyzed by FTIR spectroscopy (TG/FTIR). The hydrogen was detected by TPR (Temperature Programmed Reaction) tests. The results showed that in the presence of ZnO the cellulose thermal degradation produced larger amounts of H2 when compared to pure cellulose. The process was also carried out in a tubular furnace with N2 atmosphere, at temperatures up to 900 °C, and different heating rates. The nanostructures growth was catalyst-free, without pressure reduction, at temperatures lower than those required in the carbothermal reduction of ZnO with fossil carbon. The nanostructures were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The optical properties were investigated by photoluminescence (PL). One mechanism was presented in an attempt to explain the synthesis of zinc nanostructures that are crystalline, were obtained without significant re-oxidation and whose morphologies are dependent on the heating rates of the process. This route presents a potential use as an industrial process taking into account the simple operational conditions, the low costs of cellulose and the importance of bio-hydrogen and nanostructured zinc.

Na contramão do jornalismo Fast: as relações de subordinação entre mercado e universidade e a necessidade de se repensar a pedagogia do jornalismo

The Brazilian Journalism graduation was created in 1947, when Casper Líbero Foundation has teamed up with Philosophy's Faculty of the São Paulo's Catholic University and built the first Communication course in the country. Since then, the journalism curriculum has undergone several renovations, which influenced the profession in the country: five Currículos mínimos were created in 20 years, with the purpose of regulate journalism in the country, according to differents interests. These Curriculum left marks in Journalism that we feel today, like the perception that Journalism is a Communication's license, forcing students to be a versatile professional. Moreover, Journalism has serious teaching deficit, which separates theory from practice (functionalist perception). For the reasons above, experts in Communication, with the purpose of change the negative influence of these Currículos Mínimos, released a report in 2009, approved in 2013, with the Journalism's National Guidelines for the Journalism's graduation. The document intend to guide the discussion of the reformulation for the Journalism's curriculum in Brazil. Specifically, this paper seeks to contribute to the discussion of curriculum, of Political Pedagogic Project and national guidelines in the São Paulo State University - Universidade Estadual Paulista, UNESP. In this regard, the paper's applicant makes a study of the guidelines contained in the previous and current curriculum proposals, dissects the Journalism's National Curriculum Guidelines and offers help to speed up the discussion of the new Political Pedagogic Project for the journalism course
