A theoretical and experimental study to unequivocal structural assignment of tetrahydroquinoline derivatives

The tetrahydroquinoline derivatives can be easily synthesized through Povarov reaction and have several important biological activities. This work describes a comparative study for the unequivocal assignment of molecular structure of different tetrahydroquinoline derivatives, through a complete analysis of NMR 1D and 2D NMR spectra (1H, 13C, COSY, HSQC, and HMBC), and the correlation this data with theoretical calculations of energy-minimization and chemical shift (δ), employing the theory level of DFT/B3LYP with set of the cc-pVDZ basis. For these derivatives the experimental analyses and the theoretical model adopted were sufficient to obtain a good description of its structures, and these results can be used to assign the structure of various others tetrahydroquinoline derivatives. © 2013 Springer Science+Business Media New York.

Diretrizes para implantação coletiva e semipresencial de sistemas certificáveis de gestão

This paper aims to develop guidelines for the collective and semi-presence-based implementation of (a situation in which there is no active participation of a consultant specialist in the company) certifiable management systems. These systems include ISO 9001, ISO 14001, or OHSAS 18001. This is a theoretical and conceptual study which was based on four practical experiences of the theory of collective and semi-presence-based system implementation for the development of the guidelines proposed. These guidelines are drawn up according to the following items: selection of companies; awareness, diagnosis, planning, training, implementation, verification and improvement.

Guidelines for the integration of certifiable management systems in industrial companies

Organizations often operate in turbulent environments characterized by intense competitiveness, constant technological progress, new market requirements, and scarce natural resources. This scenario imposes the constant need for change in the operation and companies' management. The integration of certifiable management systems is an effective alternative in this sense. The objective of the present study is to propose guidelines for the integration of the ISO 9001 Quality Management System (QMS), ISO 14001 Environmental Management System (EMS) and OHSAS 18001 Occupational Health and Safety Management System (OHSMS) in industrial companies. These guidelines were developed based on a theoretical framework and on the results from fourteen case studies performed in Brazilian industrial companies. The proposed guidelines were divided into three phases: A) integration planning, b) integration development, and c) integration control and improvement.

Impacto da ABNT NBR 15575 na qualidade da construção civil

The quality in construction is increasingly a concern in this sector, in view of the occurrence of problems in civil works, even when a contractor is certified by ISO 9001. The ISO 9001 certification does not ensure the maintenance of quality because it only establishes the requirements for a quality management system (QMS) to ensure standardization of processes and products. With the development of ISO 15575, standard performance, the builders took on a quality parameter with the requirements established by this Standard, which must be met. Thus, the implementation of a quality management system (QMS) becomes essential, showing users the concern for quality. This study aimed to verify, through a case study, the impact of NBR 15575 quality construction and how that standard of performance may be the key element of ISO 9001 to ensure quality maintenance of civil works

Comunicação interna: uma questão de qualidade

Internal Communications, a central theme of this project, it is essential to support a transparent and effective cooperation between organization and em ployee. In companies with Quality Management System, as certified in ISO 9001, need to adhere to the quality not only in its management policy, but as in all of its processes and the various agencies in which there is interaction, especially the internal. This paper aims to reflect on the interaction with the internal audience, paying attention to the fact that the information required and the strategic management of public relations positively interfere in the relationship between organization and employe e and the resulting benefits that these entail in quality management. The demonstration of the policies employed by the company Vien a Grafica & Editora as the basis for developing a model suggestive of internal communication in business quality. Thus, we intend to understand how effective communication arouses feelings of motivation and engagement among employees, so there is the realization of quality in all organizational sectors

Gestão de portfólio de produtos em pequenas empresas de base tecnológica

The product portfólio management is considered relevant activity to the proper performance of the product development process. This paper aims to present the main methods of management that technology-based small businesses adopt for decision-making in product portfolio. This survey, which collected data on 31 companies was conducted. It was observed that although firms adopt market research and mapping methods and financial methods and for this decision-making, most of them based on the informal deliberations of senior management. Unable to understand the business relationships between the presence of ISO 9001 certification with greater formalization for decision making in product portfolio.
