Avaliação termográfica de instalações de refrigeração

Numa sociedade em que a utilização racional de energia constitui cada vez mais uma prioridade, é pertinente a avaliação do desempenho energético dos equipamentos que actualmente se encontram em funcionamento nas diferentes instalações industriais e agro-industriais. Em particular, no distrito de Castelo Branco existem várias empresas que utilizam o “Frio” como parte do seu processo produtivo ou como método de conservação de produtos e que contribuem para o epíteto “Castelo Branco, Capital do Frio”. No presente estudo efectua-se um diagnóstico energético das câmaras frigoríficas com recurso à Termografia por Infravermelhos (TIV)

Integrated versus non-integrated perspectives of auditors concerning the new ISO 9001 revision

The process of integration of management systems is being unfolded by a great deal of companies nowadays. A crucial feature of it relates with the audit function and the integrated perceptions of the auditors. This issue is of utmost importance if one takes into account the remarkable effort developed by ISO in the last revisions (2015) of the ISO 9001 and ISO 14001 standards aiming at the standards integration by adopting a common high level structure, identical core context, and common terms and common definitions. The available drafts of the new ISO 45001 standard suggest the same effort. This paper aims, within a global research study on ISO 9001:2015, to report the integrated versus non-integrated perspectives of auditors concerning the new ISO 9001 revision based on the results from a survey conducted among IRCA auditors. It is intended specifically to assess if the perceptions from the auditors holding several certifications are different of those from the auditors that hold solely the QMS certification. Results suggest that the auditors holding several certifications foreseen more benefits from this new revision, i.e., auditors with a wider integrated perspective rate systematically higher the different dimensions assessed in this survey.The authors would like to thank to all the responding auditors for their great collaboration and will pursue this study by applying more powerful statistical tools and adding a time perspective by replicating the survey in the future.

ISO 22000 standard implementation: Benefits, motivations and obstacles

Purpose - The aim of this paper is to evaluate benefits, motivations, and obstacles of the implementation of ISO 22000 in the food industry and do a comparative relation in multiple countries. The study identifies the main difficulties faced by companies during the adoption process and the benefits found on their overall satisfaction with ISO 22000. Design/methodology/approach - A research was performed to identify the existence of studies about difficulties and benefits of ISO 22000 implementation. The literature review resulted in the selection of studies about the Food Safety Management System (FSMS) in different countries, with special focus on ISO 2200 implications. Findings - There are several benefits that companies can obtain from having an implemented and certified FSMS. It is possible to observe similar benefits when ISO 22000 is implemented. The difficulties to the implementation of ISO 2200 were identified by all companies, however they demonstrated to be pleased with the benefits (internal and external) of the certification. Research limitations A small percentage of papers were found about the ISO 22000 implementation. Most case studies focus on Food Safety without a specific focus on ISO 22000. Originality/value - The studied papers comprised certified companies and analyzed benefits and obstacles of the implementation of ISO 22000, including representatives of all links in the Food Chain.(undefined)info:eu-repo/semantics/publishedVersio

Monitorização óptica da evolução de deformações em edifícios históricos

As estruturas de património arquitectónico apresentam, pela sua natureza e história, um elevado desafio no campo da conservação. Para vencer esse desafio é indispensável combinar o conhecimento e experiência científico e cultural para o estudo exaustivo das melhores soluções a aplicar, quer no âmbito da análise e diagnóstico, quer no âmbito da intervenção e conservação. Com o objectivo de facultar meios de análise e diagnóstico adequados ao património arquitectónico, foram desenvolvidos e implementados sistemas ópticos para monitorização estrutural. Um dos sistemas tem por base o uso de sensores de fibra óptica baseados em redes de Bragg. Um outro sistema tem por base a medição laser de distâncias por diferença de fase

Potential for technological modernisation and innovation based on ICT in agri-food companies of central region of Portugal

This paper assesses the potential for technological modernisation and innovation based on Information and Communication Technologies (ICT) in agri-food companies located in the central region of Portugal. The survey was applied to 50 agri-food companies of Cereals, Cheese, Olive oil, Dry sausages, Honey, Wine, and Horticultural sectors. Survey results can be summarised as: The large majority of companies use computers and have Internet service. Most of companies don't have a webpage and neither use Internet for advertising campaigns, selling or buying products. Half of companies use social networks for business purposes. Most companies haven't promoted collaborators training in ICT in the last year. Companies claim that possessing a webpage and attending ICT training will be the technological solutions that will improve their productivity and/or marketing products and services. For each sector, recommendations and suggestions were provided in order to promote the use of ICT for business purposes.info:eu-repo/semantics/publishedVersio
