13. Efeitos da bromocriptina na prevenção da síndrome do hiperestímulo ovariano precoce em mulheres de alto risco submetidas a fertilização in vitro / Effects of bromocriptine in the prevention of early ovarian hyperstimulation syndrome in high risk women submitted to in vitro fertilization
Objective: To evaluate the effect of bromocriptine for the prevention of either early moderate or severe ovarian hyperstimulation syndrome (OHSS) in high risk women submitted to in vitro fertilization. Patients and Methods: A double-blind, prospective, randomized study was carried out between February 2006 and November 2007 at the Human Reproduction Center,

14. Double sampling control chart for a first order autoregressive process
Neste artigo propomos o gráfico de controle de amostragem dupla para monitoramento de processos nos quais as observações seguem um modelo autoregressivo de primeira ordem. Nós consideramos intervalos de amostragem suficientemente longos em linha com o conceito de subgrupos racionais. O gráfico de controle de amostragem dupla é substancialmente mais efi

15. ASPECTOS NUTRICIONAIS DE UM SISTEMA AGROFLORESTAL COM EUCALIPTO NO SUL DO RIO GRANDE DO SUL, BRASIL / NUTRITIONAL ASPECTS IN AN AGROFORESTRY SYSTEM WITH EUCALYPTUS IN SOUTH BRAZIL
This study was conducted at an experimental area at Aroeira Farm, belonging to Votorantim Celulose e Papel company, under the geographic coordinates 31 45 50.7 S e 53 50 34.9 W, located in Candiota county. In the area there is an experimental field, where some production factors involved in an agroflorestry system are being monitored, with four different tre

16. Segregação no transporte de fertilizantes comercializados em embalagens "BiG Bag"
The majority of mineral fertilizers used in Brazil are sold in the form of granules mixture in order to provide, lower storage and transportation costs, lower probability of hardening, easier handling and also to simplify its use. Despite the advantages mentioned, such mixtures, which might present two or three primary macronutrients, secondary macronutrient

17. DOUBLE-SAMPLING CONTROL CHARTS FOR ATTRIBUTES / GRÁFICOS DE CONTROLE POR ATRIBUTOS COM AMOSTRAGEM DUPLA
In this thesis, it is proposed the incorporation of the double-sampling strategy, used in lot inspection, to the np control chart (control chart for the number nonconforming), with the purpose of improving its efficiency, that is, reducing the out-of-control average run length (ARL1), without increasing the average sample size (ASS) or the in-control average

18. CHARACTERISTICS OF RAINFALL AND PRECIPITATION FEATURES DEFINED BY THE TROPICAL RAINFALL MEASURING MISSION OVER SOUTH AMERICA
The performance of the Tropical Rainfall Measuring Mission (TRMM) rainfall algorithms was investigated from December 1997 to November 2000 over South America and adjoining oceans. The Precipitation Radar (PR) and the TRMM Microwave Imager (TMI) algorithms are compared with the rainfall estimates of the Geostationary Environmental Satellite (GOES) Precipitati

19. O ambiente deposicional da formação Carajas e uma proposta de modelo evolutivo para a Bacia Grão Para
The large Carajás iron ores belongs to the Carajás formation, which is a 100-400m thick banded and laminated iron formation (jaspilite), located at Pará state in North Brazil. This almost continuous formation outcrops for at least 260km, in 60 ore deposits, distributed in three main ridges, São Felix, Leste and Carajás. The last one is a sinformal struc

20. Larval dispersal and predation in experimental populations of Chrysomya albiceps and Cochliomyia macellaria (Diptera: Calliphoridae)
In this study we investigated the larval dispersal associated with larval predation in experimental populations of Chrysomya albiceps and Cochliomyia macellaria. Frequency distribution of sampling units (G test) in the substrate was used to evaluate variation in larval dispersal. An experimental acrylic channel (1 x 0.1 x 0.2 m) covered with wood shavings wa

21. Floristica, fitossociologia e caracterização sucessional em uma floresta estacional semidecidual : Mata da Virginia,Matão, SP
This work was developed in the mata da Virgínia, with 2.072,64ha, being one of the biggest remnants of semidecidual stational forest of the São Paulo state, situated in a farmer named Cambuhy between the cities of Matão and Tabatinga ( 48°. 30 W e 21°.35 5). Different physiognomy were identified in the forest from the analysis of aerial photos and some

22. Quimiotaxia de polimorfonucleares em crianças gravemente enfermas
This study examined the in vitro chemotaxis of polymorphonuclear leukocytes (PMNs) obtained from critical care children admitted to a pediatric intensive care unit. The investigation was carried out in three stages. In the first, cells from eight patients and eight healthy volunteers were used to standardize the conditions for the chemotaxis assay. For this

23. Base pair opening within B-DNA: free energy pathways for GC and AT pairs from umbrella sampling simulations
The conformational pathways and the free energy variations for base opening into the major and minor grooves of a B-DNA duplex are studied using umbrella sampling molecular dynamics simulations. We compare both GC and AT base pair opening within a double-stranded d(GAGAGAGAGAGAG)· d(CTCTCTCTCTCTC) oligomer, and we are also able to study the impact of openin

24. Elbow Flexibility of the kt38 RNA Kink-Turn Motif Investigated by Free-Energy Molecular Dynamics Simulations
Kink-turns (K-turns) are common structural motifs that can introduce sharp kinks into double-stranded RNA, and have been proposed to mediate large-scale motions in the ribosome. K-turns consist of a bulge loop region flanked by trans sugar-Hoogsteen G:A pairs, and the sharp kink conformation is stabilized by A-minor interactions (adenine contacting a G:C bas
