Abstract: high grade deposits were mined in the early stages of the activity. no attention was paid to maximizing the use of the deposits. even nowadays, millions of tons of useful minerals are discarded every year into tailings ponds. this study investigated the possibility of economically retrieving ultrafine tailings (slimes) from an iron ore concentrator via reverse cationic flotation. the promising results of the bench scale tests led to carrying out pilot-scale tests. it was observed that a reverse cationic column flotation process, using high depressant dosage was selective, yielding high levels of iron recovery, approximately 60% mass recovery and 80 % metallic recovery in the flotation stage, from 9 to 12 % of fe in the tailing and from 0,55 % to 0,90 % of sio2 in the concentrate (sio2+al2o3 < 2,00 %). the ultrafines flotation is an economic alternative for increasing the recovery in mineral processing operations. the flotation of ultrafines may also be evaluated for decreasing or treating effluents disposed to the environment.
COMPARA O DE SISTEMAS DE COLHEITA MECANIZADA E SEMIMECANIZADA NA PERDA, DANO MEC NICO E IMPUREZA DE GR OS NA CULTURA DO FEIJOEIRO (Phaseolus vulgaris L.)

Abstract: As dificuldades constatadas na colheita mecanizada do feijoeiro ainda constitui em um obstáculo para a expans o da cultura. Diante disto, o CNPAF vem se esfor ando para o melhoramento da espécie buscando características adequadas à colheita mecanizada. A cultivar Safira atende a este objetivo. Neste sentido foi realizado um experimento na Fazenda Três Irm os, no município de Santa Helena de Goiás (GO), onde se compararam três sistemas de colheita, objetivando avaliar perdas de gr os, bem como a qualidade do produto colhido, através da análise de gr os quebrados e impurezas, na cultivar Safira. Os resultados demonstraram que a colheita mecanizada do feijoeiro para a cultivar Safira é viável. A automotriz recolhedora causa menor perda de gr os, mas o dano mecanico é elevado; a recolhedora-trilhadora apresentou perda satisfatória, apesar de exigir manuseio adequado. PALAVRAS-CHAVE: Feij o; culturas anuais; mecaniza o agrícola. The mechanization of the crop of the bean still constitutes an obstacle for the expansion of the culture. Due to this fact, CNPAF is making an effort to the improvement of the species looking for favorable characteristics to the mechanized crop. The cultivar ‘Safira’ fulfills this aim. In this sense, an experiment was carried out at Fazenda Três Irm os, in the district of Santa Helena of Goiás (GO). Three crop systems were tested in order to evaluate losses of grains and the quality of the picked product, through analysis of broken grains and sludges. The results demonstrated that the mechanized crop of bean concerning the cultivar ‘Safira’ is viable. The self-driven retirement causes a smaller loss of grains, but the mechanical damage is higher; the retirement-thrashing showed satisfactory loss, despite of requiring adequate handling. KEY-WORDS: Bean; annual cultures; agricultural mechanization.

O componente medioestrutural do minidicionário escolar Caldas Aulete
Eduarda Barbosa DUARTE,Antnio Luciano PONTES
Entrepalavras : Revista de Linguística do Departamento de Letras Vernáculas da UFC , 2012,
Abstract: Os dicionários s o caracterizados, dentre outros aspectos, por seu caráter essencialmente didático (PONTES, 2009). Essas obras auxiliam na descoberta de novas palavras e de seus significados, grafias, pronúncias, contextos de uso, além de sin nimos e de ant nimos, por exemplo. Sendo o domínio do léxico um dos critérios básicos para o aprendizado de uma língua, essas obras tornam-se ferramentas indispensáveis em qualquer sala de aula de língua, seja ela materna ou estrangeira. Partindo desse pressuposto, o conhecimento das estruturas que formam o dicionário pode ajudar na melhor utiliza o dessas obras lexicográficas, fazendo com que o consulente possa fazer uma busca de palavras, ou qualquer outra informa o da qual precise, de forma mais eficiente e rápida. Os níveis estruturais presentes no dicionários o: a megaestrutura, a macroestrutura, a medioestrutura e a microestrutura (PONTES, 2009). Nosso objetivo, com este trabalho, é apresentar, exemplificar e classificar um dos quatro níveis estruturais das obras lexicográficas, a saber, a medioestrutura, responsável pelo diálogo entre as outras estruturas do dicionário e entre as partes que integram a microestrutura. Nosso trabalho fundamenta-se em teóricos da Metalexicografia e da Lexicografia Pedagógica, como Damim (2005), Heinrich (2007), Pontes (2009) e Welker (2004). O dicionário analisado será: Caldas Aulete: Minidicionário Contemporaneo da Língua Portuguesa (AULETE, 2004). Esta pesquisa foi desenvolvida sob orienta o do Prof. Dr. Antonio Luciano Pontes do Programa de Pós-gradua o em Linguística Aplicada (PosLA), da Universidade Estadual do Ceará (UECE) no ambito do Grupo de Pesquisa Lexicografia, Terminologia e Ensino (LETENS).

Abstract: Este estudo investigou o efeito da interferência contextual (IC) na aquisi o do servi o do voleibol em adolescentes com diferentes níveis de habilidade, considerando os testes de transferência imediato e retardado. A amostra foi composta por 56 meninas com idade entre 14 e 16 anos, distribuídas em quatro grupos de prática: aleatório com nível superior de habilidade (GAS), blocos com nível superior de habilidade (GBS), aleatório com nível inferior de habilidade (GAI) e blocos com nível inferior de habilidade (GBI). A tarefa motora consistiu dos servi os por baixo e por cima direcionados a alvos na quadra. Os resultados mostraram que o efeito da IC n o foi observado nos grupos GAI e GBI, por outro lado, os grupos GAS e GBS apresentaram melhor desempenho no teste de transferência imediato. A ausência de diferen as significativas no teste de transferência retardado sugere que o efeito da IC pode ser temporário. Este estudio investigó el efecto de la interferencia contextual (IC) en la adquisición del servicio de voleibol en adolescentes con diferentes niveles de habilidad, teniendo en cuenta las pruebas de transferencia inmediata y retardada. La muestra estuvo conformada por 56 ni as de edades comprendidas entre 14 y 16 a os, divididas en cuatro grupos de práctica: al azar con mayor nivel de habilidad (GAS), por bloques con mayor nivel de habilidad (GBS), al azar con menor nivel de habilidad (GAI ) y por bloques con menor nivel de habilidad (GBI). La tarea motora consistió de servicios por abajo y por encima dirigidos a objetivos en la cancha. Los resultados mostraron que no se observó el efecto de la IC en los grupos GAI y GBI, por otra parte, los grupos GAS y GBS presentaron mejor rendimiento en la prueba de transferencia inmediata. La ausencia de diferencias significativas en la prueba de transferencia de retraso sugiere que el efecto de la IC puede ser temporario. The purpose of this study was to investigate the effect of contextual interference on acquiring the volleyball serve in adolescents with different skill levels, considering then immediate and delayed transfer tests. Participants were 56 schoolgirls separated in four practice groups: random practice with higher level skill subjects (GAS), blocked practice with higher level skill subjects (GBS), random practice with lower level skill subjects (GAI) and blocked practice with lower level skill subjects (GBI). The acquisition task consisted in performing underhand and overhead services directed at two targets affixed to the ground. The results showed no effect of contextual interference on the low

Abstract: The use of highly active antiretroviral therapy (HAART) has significantly reduced the incidence and progression of HIV-associated cryptococcosis. However, an early complication of HAART is the immune reconstitution inflammatory syndrome (IRIS), which may affect the CNS. The authors report a patient successfully treated for cryptococcosis and HIV who presented a late manifestation of IRIS. Neuroimaging aspects and management of CNS-IRIS in this patient are discussed in this paper. 1. Introduction Cryptococcosis is a global invasive mycosis associated with significant morbidity and mortality [1]. The use of highly active antiretroviral therapy has significantly reduced the incidence and progression of HIV-associated cryptococcosis [2]. However, an early complication of ART is the immune reconstitution inflammatory syndrome (IRIS), which may affect the central nervous system (CNS). The authors report a patient successfully treated for cryptococcosis and HIV who presented a late manifestation of IRIS. Neuroimaging aspects and management of CNS-IRIS in this patient are also discussed in this paper. 2. Case Report A 26-year-old HIV-positive female was brought in to the emergency department with a history of tonic-clonic seizures 2 days earlier and bilateral lower limb weakness. Although the patient was alert and oriented, she was unable to walk. The patient had been diagnosed HIV-positive three months earlier and started taking antiretroviral medications since then, when she was admitted to hospital with a history of fever and headache. Her lymphocyte CD4+ count was then 57?cells/mm3, and HIV viral load was 89,290?copies/mL. Serum cryptococcal latex antigen test (CLAT) was positive (titer 1?:?10,000). Lumbar puncture (LP) was performed (opening pressure 780?mm?H2O), and fungal culture was positive for Cryptococcus neoformans. She was treated with serial LP, amphotericin B plus 5′flucytosine for 14 days and then started on oral fluconazole 800?mg/day. CSF cultures were negative for C. neoformans after 14 days of amphotericin B and 5′flucytosine treatment. She was discharged for followup at the outpatient clinic and started on HAART (zidovudine, lamivudine, and efavirenz). At the present admission, LP was again performed and opening pressure was 260?mm?H2O, and CSF was negative for fungi, viruses, bacteria, and mycobacteria. The patient was taking oral fluconazole 800?mg/day and HAART for two months. Serum CLAT was still positive at a titer lower than 1?:?10. Brain MRI showed diffuse swelling of the brain due to extensive edema of the white matter and collapse

Abstract: human capital, productivity and physical capital are considered the main factors in the economies' gdp per capita determination. according to the neoclassical approach, human capital accumulation explains about a third of the variation in per capita income across countries. however, there is no consensus on the ways in which human capital influences gdp per capita. the present study's goal is to compare two production functions functional forms for the brazilian states: the one developed by solow (1956) and the one developed by mincer (1974). the marginal return of education also has been estimated and we have analyzed the relevance of human capital on gdp per capita determination through a variety of estimation methods, for the 1980-2002 period. the empirical results rejected the neoclassical specification with human capital in favor of the mincerian's specification. the estimated marginal return of education is 15% and the empirical findings support the theory that states that human capital is one of the main factors affecting income level.
