Shedding light on TQM: some research findings

Over the last decad , the paradigm of Total Quality Management (TQM) has been successfully forged in our business world. TQM may be defined as something that is both complex and ambiguous; nevertheless, some key elements or principles can be mentioned which are common to all of them: customer satisfaction, continuous improvement, commitment and leadership on the part of top management, involvement and support on the part of employees, teamwork, measurement via indicators and feedback. There are, in short, two main reasons for it having spread so widely: on the one hand, the successful diffusion of ISO 9000 standards for the implementation and certification of quality management systems, standards that have been associated to the TQM paradigm, and, on the other, the also successful diffusion of self evaluation models such as the EFQM promoted by the European Foundation for Quality Management and the Malcolm Baldrige National Quality Award in the USA, promoted by the Foundation for the Malcolm Baldrige National Quality Award. However, the quality movement is not without its problems as far as its mid and long term development is concerned. In this book some research findings related to these issues are presented.

Effects of sensing temperature on the NO2-sensing properties of octa-iso-pentyloxymetallonaphthalocyanine spin-coated films

A kind of 1,6,10,15,19,24,28,33-octa-iso-pentyloxy-2,3-metallonaphthalocyanines complexes MNc(iso-PeO)(8) (M = Co, Cu, Pd) are used as spincoating film-forming materials. The surface morphologies of the films prepared were studied first. These films were then used for the experiments of NO2 sensing. The effects of sensing temperature as well as the NO concentration on the sensing properties were studied. The experimental results showed that the three MNc(iso-PeO)(8) films were uniform, smooth and dense. Due to the different metal ions (M) on the center of naphthalocyanine, the CoNc(iso-PeO)(8) film had a higher film resistance and response-recovery rate in the NO2 sensing experiments. On the contrary, the response to NO2 of the PdNc(iso-PeO)(8) and CuNc(iso-PeO)(8) films were superior to that of CoNc(iso-PeO)(8). By varying the sensing temperature, it was found that the elevation of sensing temperature could improve the sensing response, recovery ratio, and sensitivity of the sensing films. At high concentrations of NO2, the response time became shorter. (c) 2007 Elsevier B.V. All rights reserved.

Preparation, characterization and gas sensing properties of nickel octa-iso-pentyloxynaphthalocyanine spin-coating films

Spin-coated films of nickel 1,6,10,15,19,24,28,33-octa-iso-pentyloxy-2,3-naphthalocyanine complex were obtained and characterized by UV-vis absorption spectroscopy. A linear relationship between the absorbance and solution concentration was observed. Low concentration solutions could afford smooth and homogeneous film surfaces as indicated by atomic force microscopy. The film structure was studied by small angle X-ray diffraction. The films were used for NO2 sensing experiments. The results indicate that the elevation of sensing temperature can shorten the response time and increase recovery ratio and response magnitude of the sensing films. High NO2 concentration can also shorten response time. (C) 2008 Elsevier B.V. All rights reserved.

La gestión de la calidad y la responsabilidad social corporativa del sector de la automoción en la región de Tánger-Tetuán (Marruecos)

[ES]En el presente artículo se pretende estudiar el grado de implantación de los ocho principios de calidad, la norma ISO/TS 16949 y algunas cuestiones relativas a la RSC en la industria automotriz instalada en la región de Tánger-Tetuán (Marruecos). Para ello, se ha llevado a cabo una investigación empírica que emplea un cuestionario para recoger la información necesaria. Los diferentes aspectos tratados en nuestro estudio están agrupados en el cuestionario en diez bloques. A partir de los resultados obtenidos,cabe concluir que la tendencia general de las empresas encuestadas es asegurar la parte relacionada con los procesos y certificación mientras que las acciones relacionadas con la formación y la RSC no están desarrolladas satisfactoriamente.

Avaliações técnico-operacionais em estações de tratamento de água dos municípios das regiões leste e dos lagos do Estado do Rio de Janeiro, com propostas de melhorias para futura implantação de sistema de gestão ambiental baseado nas normas ISO 14.000.

Na gestão de recursos hídricos, as questões relacionadas aos impactos ambientais causados pelas Estações de Tratamento de Água não podem ser negligenciadas, devendo ser avaliadas em todos seus aspectos. Neste trabalho foram avaliadas as condições técnicasoperacionais e a gestão de seis Estações de Tratamento de Água de pequeno porte situadas nas regiões leste e dos lagos do estado do Rio de Janeiro. Os resultados apresentam dados de produção de água tratada, perdas de água contabilizadas com lavagem de filtros e descargas de decantadores e as não contabilizadas, gastos de energia e produtos químicos, produção de resíduos e seu destino final, bem como levantamento da capacitação do pessoal de operação, comparados com valores de literatura para ETAs consideradas eficientes. A partir da discussão dos resultados concluiu-se que há necessidade de correções de operação e manutenção das ETAs e monitoramento da qualidade das águas bruta e tratada, recomendando-se que a empresa de saneamento, efetivamente, implante melhorias para uma posterior implantação, em cada unidade, de um sistema de gestão ambiental, baseado nas normas ISO 14.000.

Effects of iso-nitrogenous fertilizers as nutrient sources on carp polyculture in Bangladesh

A 120-day long experiment was conducted to find out the effects of urea plus triple super phosphate (UT), cow manure (CM) and poultry manure (PM) having iso-nil:rogen content on pond productivity and fish yield. Three fertilizer treatments, with three replicates each, were randomly assigned into nine earthen ponds of 100 m2 each. The stocking fish were rohu (Labeo ruhita), catla ( Catla catla) and mrigal ( Cirrhinus mrigala) in each treatment pond at the rate of 10000/ha with the ratio of 1:1:1. All ponds were fertilized fortnightly at the rate of 125 kg/ha urea plus 100 kg TSP/ha, 7000 kg/ha cow manure and 3500 kg/ha poultry manure for the treatment of UT, CM and PM, respectively, having an iso-nitrogen content of 56 kg in each. Though the physicochemical water quality parameters were more or less similar in all treatment ponds, the chlorophyll-a content and abundance of total plankton were significantly higher (P < 0.05) in the ponds receiving the treatment PM. Final growth as well as per unit production of fish was significantly higher (p

Effects of iso-nitrogenous and iso-phosphorus fertilizers as nutrient sources on carp polyculture in Bangladesh

A 120 day long experiment was conducted to find out the effects of cow manure with urea and triple super phosphate (CUT), poultry manure with urea and triple super phosphate (PUT) and cow manure with poultry manure (CP) having similar quantities of nitrogen and phosphorus on pond productivity and fish yield. The stocking fish were rohu (Labeo rohita), catla ( Catla catla) and mrigal ( Cirrhinus mrigala) in each treatment pond at the rate of 10000/ha. All ponds were fertilized fortnightly at the rate of 4000 kg/ha cow manure with 62 kg/ha urea and 65 kg/ha TSP, 2700 kg/ha poultry manure with 62 kg/ha urea and 16 kg/ha TSP, and 4000kg/ha cow manure with 2700 kg/ha poultry manure for the treatment CUT, PUT and CP respectively. Each treatment contained an iso-nitrogen and iso-phosphorus of 56 kg and 46 kg respectively. Though the physico-chemical parameters were more or less similar in all ponds, the chlorophyll-a content and abundance of total plankton were significantly higher (P< 0.05) in the ponds receiving the fertilizer treatment of PUT than those of other treatments. Final growth as well as per unit production of fish of treatment PUT (1773 kg/ha) was significantly higher (P< 0.05) than that of treatment CP (1528 kg/ha) followed by that of treatment CUT (1336 kg/ha). The over all results showed that poultry manure with urea and triple super phosphate proved to be superior to cow manure with urea and triple super phosphate, and poultry manure with cow manure, even when nitrogen and phosphorus content was similar, in carp polyculture system under prevailing conditions.
