Health care waste (HCW) is the type of waste that results from activities performed in health care services during care provision to humans or animals. Presently, according to RDC 306/04, issued in 2004 by Anvisa, and Resolution no. 358/05, by CONAMA, waste groups have the following classification: Group A (biological waste), Group B (chemical waste), Group C (waste containing radionucleotides), Group D (common waste) and Group E (piercing and cutting waste). In Brazil, 149 tons of wastes are collected every day, and HCW corresponds to approximately 1% to 3 % of that total. An efficient way to adequately manage HCW is through the Health Care Waste Management Plan (HCWMP), and it is possible to reduce the risk posed by certain materials in addition to ensuring disposal in an ecologically correct and economical fashion. According to the Pan-American Health Organization (PAHO), the management process enables health care establishments to adequately manage waste. Hence, there is greater control and reduction in the health risks caused by infectious or special waste, in addition to facilitated recycling, treatment, storage, transport and final disposal of solid hospital waste in an environmentally safe fashion. To evaluate the management of HCW of Groups A and D from the Intensive Care Unit of the University Emergency Hospital - FMB - UNESP in the city of Botucatu according to the guidelines presently in force. The waste flow was followed up, and during four random days in the month of September 2011, waste was quantified by estimating daily and monthly values, according to its classification. : In 2011, the University hospital has produced an average of 57,676.8 kg/month of biological and common waste. By adding Groups A and D, during the four days, approximately 209.8 Kg of waste (202.2 Kg of Group A and 7.6 Kg of Group D) were produced in the establishment under study, which...

The current problematic of the construction and demolition (C&D) waste faced for the Brazilian cities, is one of the main degradation factors of the environment, over all about the promise of the urban ambient quality. This scenery must mainly to the unsustainable management adopted by the great majority of the Brazilian cities. Therefore, this work aims at to offer subsidies for medium cities, having as study object the city of Rio Claro-SP, (Brazil), in the elaboration of plans and integrated programs of sustainable management of the construction and demolition waste, in accordance with CONAMA Resolution nº 307/2002, that’s set up a sustainable management system of C&D waste. In this direction, the diagnosis of the management was elaborated for the city of Rio Claro, (generation, collects, transport and disposal) and the public administration of the construction and demolition waste, as well as of the study of the related aspects with C&D waste recycling plant. Later, was suggested a plan of improvements for the public manager of C&D waste: areas of temporary disposal to facility the appropriating destination, appropriated areas of final disposal, incentives to the recycling of C&D waste, new legislations, education and orientation programs and adequacy the agents of C&D waste management (generating, transporting, addressee and public manager), directing for an environmental, economic and social sustainability.

The theme of solid waste is in high evidence today, a fact noted by the recent implementation of the European directive, and in Brazil, by the National Solid Waste Policy. Understanding the impact of this policy on the national scientific production is essential to plan new directions and research trends. Through a bibliometric and scientometric studied, this research analyzed the national and global context of the last 20 years and found areas in which research progressed, as municipal solid waste, and essentials gaps to develop more the national state-of-the-art, as solid waste of transport. So, the results of this study are a plausible tool to justify for further research on this topic.

The objective of this experiment was to evaluate the inclusion of meal of tilapia industrial waster in bullfrog tadpoles' diets (Rana Catesbeina Shaw, 1802). Two hundred fifty tadpoles with initial weight and length of 0,18 +/- 0,05g and 2,50 +/- 0,18 centimeters were used, respectively, they were used and distributed in 25 aquariums of 30 liter each in a complete randomized design with five treatments and five repetitions. The tadpoles were fed four times a day with diets containing 0, 5, 10 and 15% of inclusion of tilapia filleting and another diet with 0% of supplemented tilapia filleting with synthetic methionine, being supplied four times a day at ease. The experiment period was 30 days. The diets with tilapia filleting inclusion and methionine supplementation did not have influence in the final weight and length averages, feed survival and conversion of bullfrog tadpoles. It cam be used until 15% of tilapia filleting inclusion in the bullfrog tadpoles food. The synthetic methionine supplementation in diets for bullfrog tadpoles is not necessary in diets with levels over 0,471/4 of the total methionine.

Os objetivos deste trabalho foram testar a eficiência do sal como redutor de estresse e verificar a melhor densidade de transporte de juvenis de tambaqui (Colossoma macropomun) em caixas de plástico adaptadas. No primeiro experimento foram testadas diferentes concentrações de sal de cozinha (NaCl) na água; no segundo, o transporte foi realizado por três horas em caixas de plástico de 200 L estocadas com diferentes densidades de peixe, com 8 g de sal/L de água. O cortisol plasmático dos peixes sofreu aumento significativo após o transporte no tratamento sem sal e com 2 g de sal/L de água, retornando para níveis normais após 96 horas. A glicose plasmática dos peixes sofreu aumento após o transporte em todas as concentrações de sal testadas, com exceção da com 8 g/L de água, retornando para níveis normais em 24 horas. Nos peixes transportados no segundo experimento, com 8 g de sal/L de água, não foi verificada mudança significativa no cortisol plasmático, mas a glicose aumentou significativamente em todas as densidades após o transporte, retornando para níveis normais em 24 horas. Houve mortalidade de 11% em uma das repetições da densidade de 200 kg/m³ de água. Para o transporte com 8 g de sal/L de água, a densidade máxima deve ser de 150 kg/m³ de água. Nesta densidade os parâmetros físico-químicos de qualidade de água se mantêm com características adequadas, as respostas ao estresse são mínimas e não há mortalidade.

O objetivo do trabalho foi verificar a influência dos resíduos de calda sulfocálcica sobre a eficiência de acaricidas empregados no controle de Brevipalpus phoenicis. Inicialmente, o experimento foi instalado em um pomar de citros, em que foram selecionadas 10 plantas que continham frutos com verrugose. Realizou-se a aplicação de calda sulfocálcica (8g i.a. L-1 de água) em cinco plantas e as outras cinco plantas permaneceram sem aplicação de produto fitossanitário. Protegeram-se, com copos de plástico transparente de 500mL, 64 frutos nas plantas tratadas com calda e 64 frutos nas plantas não-tratadas, totalizando 128 frutos protegidos. Decorridos 30 dias da aplicação, os frutos foram colhidos e levados para o laboratório. Estes frutos foram parcialmente parafinados, deixando-se em cada fruto uma arena de 2,5cm de diâmetro com verrugose e sem parafina, delimitada com cola entomológica. em seguida, procedeu-se à aplicação sobre os frutos em Torre de Potter dos seguintes acaricidas nas concentrações expressas em mg de ingrediente ativo por litro de água: propargite a 720mg, óxido de fenbutatina a 400mg, cyhexatin a 250mg, azocyclotin a 250mg, fenpyroximate a 50mg, dicofol a 960mg e dinocap a 738mg e a testemunha sem aplicação de acaricida. Após 1, 7 e 16 dias da aplicação, transferiram-se para cada fruto 10 ácaros B. phoenicis para avaliar a mortalidade. Constatou-se que os resíduos de calda sulfocálcica não prejudicaram a eficiência dos acaricidas avaliados no controle de B. phoenicis.
