Objective: The objective of this study is to investigate how grain production structured in Brazil, what quantities are produced which geographical spaces and, above all, whether the expansion plantations has caused environmental impact. Theoretical Framework: model for modern agriculture adds, addition concept sustainability, certified traceability production. responsible consumption grown lately, and a warning sign eventual producers who try distance themselves from these principles start...
Objetivos: Relatar um caso raro de sarcoma veia cava inferior e revisão literatura sobre o tema. Metodologia: Consulta ao prontuário do paciente da no PUBMED. Resultados: Paciente feminina, 56 anos, hipertensa, com epigastralgia há 5 meses. Exame físico mostrou abdome globoso sem massas palpáveis. Tomografia revelou lesão nodular vascularizada na (7,5 x 6,6 5,9 cm), abaixo 4 cm óstio das veias hepáticas nível renais. Foi realizada ressecção parcial nefrectomia direita, ligadura renal...
Abstract In the present work, Halide Activated Pack Cementation (HAPC) was adopted to form protective aluminide coatings due its versatility and low cost. Codeposition of Al Si on Mar-M246 performed by HAPC using two different cements constituted 75 wt.% Al2O3 25 a mixture formed in weight ratios (Al: Si): PM I (50:50) II (72.5:27.5). The are composed outer part NiAl Ni2Al3 phases with significant presence I. After 200 h oxidation test at 1000 °C, samples coated exhibited best performance...
Background: Few studies evaluate the satisfaction of patients with cancer receiving palliative care nursing received. Objective: To among in hospitalised respect to they Method: This was a quantitative, descriptive-correlational and cross-sectional study that reported accordance Strengthening Reporting Observational Studies Epidemiology (STROBE) guidelines. It carried out university hospital city Belém, Brazil. The participants were adults who had been for more than 72 hours. Data collection...
The aluminum bronze alloy is part of a class highly reliable materials due to high mechanical strength and corrosion resistence being used in the aerospace shipbuilding industry. It's machined produce parts after its use cycle, it's discarded, but third process considered expensive besides not correct for environment reasons. Thus, reusing this material through powder metallurgy (PM) route advantageous. chips were submitted energy ball milling with 3% niobium carbide (NbC) addition. NbC...
In the present work, mixed manganese-copper ferrite of composition MnxCu1-xFe2O4 (within x=0.40, 0.42, 0.44, 0.46, 0.48 and 0.50) have been investigated for their electric magnetic properties such as dc resistivity, Curie temperature, saturation magnetization. samples were prepared by uniaxial pressing from oxide mixture, synthesized at 1000°C during 45 hours finally heated to 1200°C 5h, room atmosphere. The X-ray diffractograms show that with different compositions formed compact structure...
The AISI 52100 is a tool-type steel and more often used in industry for the production of bearings. After end its life cycle, it discarded or remelted, but both processes are considered expensive. Thus, possibility reusing this material through powder metallurgy (PM) route advantageous, since transforms waste into another product. To obtain starting powders, scrap was submitted to process high energy ball milling, which milled pure with 1 3 % niobium carbide (NbC) additions. Those additions...
Brazilian aeronautical industries report that, due to the high mechanical properties presented commercially, AA2024-T351 alloy presents fissures and non-homogeneous deformations during processing. This work proposes a manufacturing process capable of increasing ductility material withstand tensions processing subsequent treatment recover strength alloy. The sequence operations begins with super-heat at 415ºC 2.5 h, solubilization 495ºC 2.0 conformation degree area reduction from10% 90%...
The AISI 52100 is a tool steel used in industry to produce bearings. After the end of its life cycle, it remelted or discarded deposits. powder metallurgy rises as an alternative recycle this material without any waste. steps by included: Machining with speed 45 rpm, high energy ball milling scraps during 30 hours mass/sphere relation 1:15 and 400 uniaxial pressing using 175 MPa sintering through minutes at 1200ºC. Also, were incorporated 1%, 3% 5% alumina particles process increase...
