1. EVALUATION OF POTENTIAL METHANE GENERATION IN THE INVESTIGATION OF AN ABANDONED CONTAMINATED LANDFILL IN SANTIAGO, CHILE
Abstract This study presents the environmental evaluation of an abandoned and potentially contaminated landfill using analyses for the presence of heavy metals and for methane generation potential. The site is located in the city of Santiago, Chile, and was used as a rural landfill for domestic, industrial and construction waste until 1978, but is now in a h

2. Construção de sistemas bacterianos para a detecção de metais pesados em amostras ambientais. / Construction of bacterial systems for the detection of heavy metals in environmental samples.
Aiming at the construction of three bacterial biosensors for metals mercury, arsenic and lead, Cupriavidus metallidurans CH34 was chosen to obtain the DNA fragments (by PCR) corresponding to operons mer, ars and pbr. The fragments were inserted upstream of the EGFP gene, in plasmid pBB-EGFP, getting three new plasmids: pGHg, pGAs and pGPb. They were cloned i

3. AplicaÃÃo do MÃtodo das Isozonas na ObtenÃÃo das EquaÃÃes IDF de Chuvas Intensas dos MunicÃpios de Juazeiro do Norte, Barbalha e Crato - CE / Isozones Method applied in the obtention of the heavy rainfall IDF equations of the Juazeiro do Norte, Barbalha and Crato (CE) municipalities.
The increase in use of urban and rural land demands knowledge on statistically treated data on intensity, duration and frequency of heavy rainfall, allowing better forecasting of peak flow rates - used in the design of drainage networks. The damage caused by flooding of urban and rural areas are only avoided by well dimensioned drainage works, resulting in c

4. Sedimentologia e cronologia por luminescência da Ilha de São Francisco do Sul (SC): considerações sobre a evolução holocênica de barreiras arenosas da costa sul e sudeste do Brasil / não infomado
São Francisco do Sul Island (SFSI) is located on the northern coast of Santa Catarina State, Brazil. It covers an area of about 265 km2 with an approximate length of oceanic coastline of 40 km. The island was formed by coastal depositional systems active during the relative sea-level changes of the last 120,000 years. The following relative sea -level fall

5. Experimental investigations on mode II fracture of concrete with crushed granite stone fine aggregate replacing sand
With a view to implement sustainability concepts (namely, use of locally available materials and industrial by-products) in the concrete construction industry, the possibility of use of crushed stone fine aggregate as replacement to river sand is explored in this paper. Towards this, tests have been carried out on concrete cubes and concrete cylinders. The e

6. LIQUID-LIQUID DISPLACEMENT FLOWS IN A HELE-SHAW CELL INCLUDING NON-NEWTONIAN EFFECTS / DESLOCAMENTO DE LÍQUIDOS EM CÉLULA DE HELE-SHAW CONSIDERANDO EFEITOS NÃO NEWTONIANOS
This work studied the displacement of fluids in porous media using a Hele-Shaw cell. Specifically, was investigated experimentally the displacement of a non-Newtonian fluid by a Newtonian in a rectangular Hele-Shaw cell. The Saffman-Taylor or viscous fingering instability occurs when one fluid pushes a more viscous one, and a Hele-Shaw is a convenient tool t

7. The internationalization process of brazilian companies: a study of multiple cases in the heavy construction industry
The aim of this article is to describe and to analyze how the consolidation in the international markets of Brazilian construction companies occurred. The methodological procedures had been classified as descriptive conclusive research and data was collected under a qualitative orientation. A study of four companies was conducted: Andrade Gutierrez, Mendes J

8. Simulação do processo de desasfaltação de petroleo pesado para obtenção de asfaltenos e oleo lubrificante / Simulation of a heavy oil deasphalting process to obtain asphaltenes and lube oil
Petroleum deasphalting is one of the major primary processes in crude oil refining. The study of deasphalting has gained considerable attention in the last few decades due to the increase in heavy crude oil reserves. In Brazil, the majority of the explored reserves produce heavy oils. The increasing reduction in the processing of light oils, added to the inc

9. Estratégias para expressão de um anticorpo anti-CD3 humanizado em células de mamífero
The development of new pharmaceuticals derived from recombinant antibodies had a significant impact in the treatment of various illnesses. However, due to the structural complexity of the immunoglobulin molecule, the production of these molecules in mammal cells is still challenging. One of the difficulties is the equimolar production of heavy and light chai

10. Analysis of mechanical behavior of an expansive soil from the oil province of Urucu-AM for paving / Análise do comportamento mecânico de um solo expansivo da província petrolífera de Urucu-AM para fins de pavimentação
The establishment of transportation infrastructure is critical to the development of the Urucu- AM region, a newly developed oil exploration area in the Amazonas state. The construction of such infrastructure is challenging due to the lack of suitable materials for the construction pavement base and subbase courses and adverse weather conditions, with altern

11. Aplicação de microemulsões na solubilização de frações pesadas de petróleo
This work presents studies related to the use of microemulsions in the solubilization of heavy crude oil fractions responsible by the formation of deposits. The first stage of the work was addressed to the construction of phases diagrams, with the intention of determining the area within which the microemulsion is formed. The following systems were studied:

12. As relações entre as crenças de aprendizes e a prática de uma professora de língua inglesa no contexto da escola pública / As relações entre as crenças de aprendizes e a prática de uma professora de língua inglesa no contexto da escola pública
A growing interest in beliefs about language learning and teaching has emerged among Applied Linguistics researchers. Nevertheless, a heavy criticism on the research in the area has been occurring over the last years. For some researchers (KALAJA, 1995; BARCELOS, 2000), much of the work done in the past has only sought to identify students and teachers belie
