Decomposição da palhada de forrageiras em função da adubação nitrogenada após o consórcio com milho e produtividade da soja em sucessão

The objective of this study was to evaluate the straw decomposition of the Urochloa and Panicum after intercropped with corn and nitrogen fertilization, as well as, the agronomic performance of soybean in succession. The experiment was conducted in an Oxisol in Cerrado conditions under no-tillage eight years ago. After the corn harvest intercropped with grass and cutting of forage homogenization were applied N rates (0, 50, 100 and 200 kg ha-1 of N - urea source) in coverage. The plots consisted of Urochloa brizantha,Urochloa ruziziensis and Panicum maximum Tanzânia and Mombaça sown at the time of corn sowing and subplots composed by accumulated amounts of nitrogen applied in forage plants prior to the soybean cultivation (0, 250, 500 and 1000 kg ha-1 of N, after five cuts). The experimental design was a randomized block with four replications in a split plot. Soon after the last cut of the forage, proportionate amount of fresh mass of the species of each subplot was wrapped in nylon bags called Litter Bags, these being deposited in direct contact with the soil, to determine the time of decomposition of the dry mass during a period of 150 days. The nitrogen doses, as well as, the corn intercropped with forages (except with Mombaça) interfere similarly in the straw decomposition of forage and in the soybean yield in succession. All the consortiums of corn and nitrogen fertilization predecessors determined that, at 60 days after desiccation and cutting, still remained between 50 and 60% of the initial straw for no-tillage system.

Gerenciamento dos resíduos de serviços de saúde da Unidade de Terapia Intensiva do Pronto Socorro do Hospital das Clínicas da Faculdade de Medicina de Botucatu – UNESP

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...

O estudo da usinagem em torneamento da superliga à base de níquel Pyromet 31v

The search for materials with higher properties and characteristics (wear resistance, oxidation, corrosion, etc.) has driven research of various materials. Among the materials that are being studied with such properties and characteristics are super alloys based on nickel which has an important role in the aeronautical, automotive, marine, production of gas turbines and now in space vehicles, rocket engineering , experimental aircraft, nuclear reactors, steam-powered plants, petrochemical and many other applications because besides having all the characteristics and properties mentioned above also have an excellent performance at high temperatures. The super alloy based on nickel studied in this work is the super alloy Pyromet 31v normally used in the manufacture of exhaust valves in common engines and diesel engines of high power by cater requirements such as mechanical strength and corrosion resistance at temperatures of approximately 815 ° C. The objective of this work is to produce results to demonstrate more specific information about the real influence of coatings on cutting tools and cutting fluids in turning and thus promote the optimization of the machining of these alloys. The super alloy Pyromet 31v was processed through turning, being performed with various machining parameters such as cutting speed, feed rate, depth in conditions of Minimum Amount of Fluid (MAF), abundant fluid, cutting tools with coating and without coating in early in his work life and with wear. After turning were obtained several samples of chips and the part generated during the machining process, was measured roughness of the material, subsequently made macrostructural analysis of the tools used order to detect possible wear and microstructural analysis of samples collected being that the latter was used for Optical Microscopy, Scanning Electron Microscopy (SEM) and ...

Fresamento de Eucalyptus grandis

The process of milling wood is widely used in operations such as planing and manufacturing frames . Machines like planers , desengrossadeiras , routers , moldureiras and machining centers employ the milling process for cutting wood . In this work the process of milling CNC machining center of Eucalyptus grandis was studied because this is very much used in furniture , but without consistent studies on this process . This work a CNC machining center brand TECH Z1 for analysis of surface quality ( Ra ) in relation to the variation of cutting speed and feed in concordant and discordant tangential milling and face milling was used . We used Eucalyptus grandis . Four forward speeds ( 3, 5 , 7, and 9 m / min ) for four shear rates ( 5,9; 8,4; 10,9 and 13,4 m/s ) were used. Was used for testing a cutter finishing top speed steel with helical teeth 16mm in diameter . 6 repetitions for each test condition were performed . From the results it was observed that the best results for roughness Vc = 10,9 m / s were obtained for the milling concordant with the forward speed Vf = 7 m / min. As for Vf = 5 m / min the best finish was achieved with Vc = 8,4 m /s in discordant for milling . The feedrate and cutting influenced the roughness . The senses of concordant and discordant and cut the top and the top had a significant difference in roughness
