Diagnostic de securite d'une entreprise bresilienne a partir de l'analyse des accidents du travail par la methode de l'arbre des causes

We present here the results of a study of 21 work-related accidents that occurred in a Brazilian manufacturing company. The aim was to assess the safety level of the company to improve its work accident prevention policy. In the last 6 months of 1992 and 1993, all accidents resulting in 15 days' absence from work, reported for social security purposes, were analyzed using the INRS causal tree method (ADC) and a questionnaire completed on site. Potential risk factors for accidents were identified based on the specific factors highlighted by the ADC. More universal trees were also compiled for the safety assessment. Three hundred and thirty specific accident factors were recorded (man of 15.71 per accident). This is consistent with there being multiple causes of accidents rather than the assertion of Brazilian business safety departments that accidents are due to 'dangerous' or 'unsafe' behavior. Introducing the idea of culpability into accidents prevents the implementation of an appropriate information feedback process, essential for effective prevention. However, the large number of accidents related to 'material' (78%) and 'environment' (70%) indicates that working conditions are poor. This shows that the technical risks, mostly due to unsafe machinery and equipment are not being dealt with. Seventy-five potential accident factors were identified. Of these, 35% were 'organizational', a high proportion for the company studied. Improvisation occurs at all levels, particularly at the organizational level. This is, thus a major determinant for entire series of, if not most, accident situations. The poor condition of equipment also plays a major role in accidents. The effects of poor equipment on safety exacerbate the organizational shortcomings. The company's safety intervention policy should improve the management of human resources (rules designating particular workers for particular workstations; instructions for the safe operation of machines and equipment; training of operators, etc.) and introduce programs to detect risks and to improve the safety of machines and equipment. We also recommend the establishment of a program to follow the results of any preventive measures adopted.

Influence of natural fruit juices in removing the smear layer from root surfaces - An in vitro study

Certain elements of a patient's diet may be associated with dentin hypersensitivity. The intent of this study was to evaluate the degree of removal of the smear layer from dentin surfaces by various fruit juices. A smear layer was created on extracted human teeth by manual scaling. The roots were reduced and distributed into 8 experimental groups. Distilled water was the negative control. The juices were applied by 2 methods: topical application and topical application with friction. Specimens were photomicrographed and graded according to an index of smear layer removal. With topical application, all but 2 of the tested substances resulted in significantly greater removal of the smear layer and opening of dentinal tubules than was the case with the negative control (p = 0.05); the exceptions were Gala apple and Italian grape juices, which were no different from the control. For the active application (with friction), most substances removed more smear layer than the control (p < 0.05); Gala apple, Italian grape and orange juices were similar to the control. For each of the tested substances, removal of the smear layer did not differ with the method of application (topical vs. friction; p > 0.05). It is concluded that natural fruit juices can remove the smear layer from dentin surfaces, and the efficacy of this removal varies with the type of juice. © J Can Dent Assoc 2004.

Apparent absorption of zinc from supplemental inorganic and organic sources to Nile tilapia Oreochromis niloticus juveniles

Nile tilapia Oreochromis niloticus fingerlings were fed with purified or practical diets, supplemented with 150 Ing Zn/kg, from different sources. Dry matter (DM), crude protein (CP), ether extract (EE), and gross energy (GE) apparent digestibility coefficients (ADC), as well as zinc, copper, calcium, and phosphorus apparent absorption coefficients (AAC) were determined by the addition of 0.1% chromic oxide to the diets. The supplemental zinc sources utilized were commercial grade zinc sulfate monohydrate (ZnSO 4), zinc oxide (ZnO) and a zinc amino acid complex (Zn-AA). Analytical grade zinc sulfate heptahydrate was also utilized as a standard reference zinc source. There was a significant difference between purified (74.9%) and practical (41.3%) zinc AAC for the ZnO supplemented diets (P < 0.05). The supplemental zinc sources presented similar AAC when purified diets were utilized. However, ZnSO 4 was the best supplemental zinc source when practical type diets were used. There were no significant differences between supplemental zinc AAC from ZnS0 4 (68.9%), and supplemental zinc AAC from Zn-AA (61.3%) in practical diets, but Zn-AA diet showed a statistically lower zinc AAC when compared with the standard zinc source diet (75.6%). The practical diet supplemented with ZnO had the worst supplemental zinc AAC (41.3%). Dietary copper (74.21%), calcium (70.9%), and phosphorus (71.9%) AAC of the practical diets supplemented with ZnO were statistically lower (P < 0.05) than the respective AAC of the practical ZnSO 4 supplemented diets (83.6%, 84.1%, 87.1%).The ADC of the practical ZnO supplemented diet for DM (76.3%), CP (88.6%), EE (82.4%), and GE (81.6%) were statiscally lower than the respective ADC of the ZnSO 4 practical diet (86.0, 92.7, 93.6, 89.6%, respectively) and those ADC of the Zn-AA practical diet (84.7, 92.7, 93.7, 88.2%, respectively) (P < 0.05). Hence, these results indicate that ZnSO 4 and Zn-AA have equivalent intestinal absorption as supplemental zinc sources for Nile tilapia juveniles and both are superior to ZnO. © Copyright by the World Aquaculture Society 2005.

Financing for sustainable development: visions and proposals for action from a Latin American and Caribbean perspective

Foreword Throughout the preparatory process for the World Summit on Sustainable Development and at the Summit itself, which was held in Johannesburg, South Africa, from 26 August to 4 September 2002, discussions were dominated by one central concern: the need to define and reach consensus on concrete, quantitative goals, with fixed deadlines for implementation, which were to supplement the Millennium Development Goals and facilitate progress towards an effective transition to sustainable development. Participants at the Summit explicitly affirmed the need, as a matter of urgency, to identify the financial and technical resources whereby sustainable development would become a reality and benefit directly and particularly rural and urban communities in the developing countries. The document we are now presenting is the outcome of extensive discussions held at a high-level forum during the Johannesburg Summit. Led by representatives of the Government of Mexico, the Economic Commission for Latin America and the Caribbean (ECLAC), the United Nations Development Programme (UNDP) and the Andean Development Corporation, those discussions were based on the ECLAC/UNDP study entitled Financing for sustainable development in Latin America and the Caribbean: from Monterrey to Johannesburg, which considers the opportunities and challenges for improving prospects for investment and financing for sustainable development and underscores the need to establish a new balance between the market economy and public interest through joint public/private initiatives that combine market innovation, social responsibility and appropriate regulations. Other eminent persons attending the event included heads of State, such as Gustavo Noboa, then President of Ecuador; Enrique V. Iglesias, President of the Inter-American Development Bank (IDB); José María Figueres, Managing Director of the Global Agenda of the World Economic Forum and former President of Costa Rica; and Gro Harlem Brundtland, the legendary figure who pioneered sustainable development. Valuable contributions to the discussions were made by Yolanda Kakabadse, President of the World Conservation Union; Xóchitl Gálvez Ruiz, head of the Unit for the Development of Indigenous Peoples of the Office of the President of Mexico; Cecilia López, former Minister for the Environment of Colombia; and Juan Carlos Maqueda, then Vice President of Argentina. The views emerging from the forum as set forth in this document are designed to facilitate and promote application of the Plan of Implementation of the World Summit on Sustainable Development within the framework of the Millennium Development Goals and the commitments assumed at the International Conference on Financing for Development, which was held in Monterrey, Mexico. We also aspire to continue moving forward with the adoption of measures and policies to increase investment and financing for sustainable development as well as to foster partnerships between the public and private sectors and nongovernmental organizations. We recognize, in this context, the importance of strengthening and improving public and private institutions in order to meet the operational needs associated with the effort to achieve the Millennium Development Goals and pursue the Plan of Implementation formulated in Johannesburg. We trust that this document will contribute to in-depth discussions on the application of the Plan of Implementation in the relevant forums, in particular the United Nations Commission on Sustainable Development. The Plan of Implementation of the World Summit on Sustainable Development opens up new opportunities for Latin America and the Caribbean to renew and revive their own regional agenda -with emphasis on global and especially regional public goods- and to interweave it more cohesively with the global agenda in order to promote the common interests of Latin America and the Caribbean more forcefully in international development forums. The regional agenda and the global agenda cannot be separated in a contrived manner; indeed, to an increasing degree, what we are witnessing are global environmental processes which call for action at the local level. The achievement of sustainable development in Latin America and the Caribbean, where the necessary economic, social, environmental and geopolitical conditions are combined, requires a subtle balance between the market economy, the State and the citizen. Such a balance will result in the consolidation of democratic governance in the service of human development.

Valor nutricional do farelo de algodão para alor a tilśpia do nilo (Oreochromis niloticus)

Cottonseed meals (CSM) with different protein levels (35, 39 and 40%) were evaluated to determine their chemical composition and measure apparent digestibility coefficients (ADC) of dry matter, protein, amino acids, energy, lipid and minerals for Nile tilapia. Apparent digestibility coefficients were determined using a reference purified diet containing 0.1% of chromic oxide indicator, and test diets contained 60% of reference diet and 40% of test ingredients. Results showed that apparent digestibility coefficients of cottonseed meals were different (p < 0.05). The apparent digestibility coefficients were: dry matter, 53.45-54.32%; crude protein, 71.56-74.81%; energy, 53.80-58.60%; lipid, 85.37-89.11%; phosphorus, 33.75-34.50%; calcium, 41.21-43.75%; iron, 62.02-79.85%; zinc, 0-67.41%; copper, 13.37-14.27%; essential amino acids, 71.39-79.17%; and non-essential amino acids, 77.08-82.58%. The ADC of protein did not reflect the majority of amino acids ADC showing variation in individual digestibility of amino acids and among cottonseed meals. Cottonseed meal can be used as protein succedaneum in Nile tilapia diets.
