1. Effect of calcium concentration on calcite flotation from apatite using carbonic gas
Abstract The flotation process currently considered for apatite concentration from the Santa Quitéria phosphate deposit (Brazil), involves bulk flotation of apatite and calcite with anionic collector at pH=10 followed by calcite flotation at pH=5.5, adjusted with H3PO4. Although this concept is efficient from the point of view of separation between apatite

3. EXPOSURE TO CARBONIC GAS ENRICHED ATMOSPHERE OR ELECTRICAL WATER BATH TO STUN OR KILL CHICKENS
ABSTRACTThe objective of this study was to compare the effects of two methods (electrical water bath or carbonic gas atmosphere) for stunning or killing broiler chickens prior to bleeding on weight loss due to bleeding and meat traits. A completely randomized design with 2 x 2 factorial arrangement (electrical or gas system x stunning or killing) was applied

4. Transferência de metano no sentido gás-líquido com vistas ao atendimento da demanda carbonácea da desnitrificação de esgoto sanitário
This work presents a simulation of a hybrid system for waste water treatment, in order to explain the possible use of a carbon supply on denitrification from the methane produced in an anaerobic reactor and transferred to the liquid mass of a reactor that would be removing nitrogen. It was used the biogas produced in a UASB reactor, that passed through a sto

5. Avaliação da utilização do dióxido de carbono proveniente da fermentação alcoólica no cultivo de Spirulina (Arthrospira) platensis: uso simultâneo de nitrato de sódio e sulfato de amônio como fontes de nitrogênio em fotobiorreator aberto / Evaluation of the use of carbon dioxide from alcoholic fermentation on Spirulina (Arthrospira) platensis cultivation: simultaneous use of sodium nitrate and ammonium sulphate as nitrogen sources in open photobioreactor
The main objective of this work was the evaluation of the potential of using carbon dioxide from alcoholic fermentation on Spirulina (Arthrospira) platensis cultivation, aiming to prove the feasibility of applying an effluent gas in the production of high added-value microbial biomass. In order to do so, the cyanobacterium was cultivated in laboratorial-scal

6. Avaliação comparativa de materiais poliméricos em coletores de admissão para aplicações de motores diesel / Comparative evaluation of polymeric materials on intake manifold for diesel engines application
In the modem world where we live, due to incited competition in the automobilist market, emerges the necessity an engine much more economic and il is worsen by the international competition with the Asian markets. Thus, accelerate not only the race for the raise of the quality and cost reduction of products, but also for the environment topics, such as the r

7. Esclerose lateral amiotrofica : estudo prospectivo de parametros respiratorios / Amyotrophic lateral sclerosis : prospectivestudy on respiratory parameters
The objective of this study was to evaluate the respiratory function of patients with amyotrophic lateral sclerosis (ALS), using the parameters of spirometry, maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), arterial blood gases and pulse oximetry, and monitor them during the period of 8 months. The study was crosssectional assessmen

8. Relationship of BODE Index to functional tests in chronic obstructive pulmonary disease
OBJECTIVE: To determine if there is a correlation between the BODE Index and variables assessed during the Activities of Daily Living assessment, performance on lower limber tests, and peripheral muscle impairment of the upper limb in patients with chronic obstructive pulmonary disease. MATERIALS AND METHODS: Ten men (aged 58 to 80 years old) with moderate t

9. ProduÃÃo de gÃs de sÃntese por tri-reforma do metano em reator de leito fixo
The ever increasing availability of natural gas (NG), and the abundant carbonic gas production, via fermentation of most prepared from sugar cane products (sugar cane juice, and molasses), thermoelectric generators, and refineries have enhanced the research interest of these commodities. The indirect NG conversion processes to synthesis gas (CO and H2), the

10. SÃntese de biodiesel de Ãleo de nabo forrageiro empregando metanol supercrÃtico
The biodiesel produced in this experiment was obtained from radish oil. We used two methods, one with catalyst-free supercritical methanol and the other with 5% zeolite heterogeneous catalyst (based on its total mass). To obtain biodiesel purification we used column adsorption chromatography (AOCS Cd 11c-93) from which was observed that the catalyst-free sup

12. INFLUENCE OF THE RESPIRATORY FREQUENCY ON THE ARTERIAL GASES SANGUINEOUS IN POSTOPERATIVE THE IMMEDIATE ONE OF EXPLORING LAPAROTOMIA FOR ABDOMINAL TRAUMA / A INFLUÊNCIA DA FREQUÊNCIA RESPIRATÓRIA SOBRE OS GASES SANGUÍNEOS ARTERIAIS NO PÓS - OPERATÓRIO IMEDIATO DE LAPAROTOMIA EXPLORADORA POR TRAUMA ABDOMINAL
The incidence of post-operative pulmonary complications is large, in consequence of the manipulation of abdominal cavity with changes on pulmonary volumes and capacities, resulting in atelectasis and hypoxemy. Alteration of breath pattern in association with postoperative pain can interfere in gaseous exchanges with larger repercussions in the presence of ri
