13. Bronchiolitis Hospitalization in Southern Brazil from 2002 to 2012: A Count Time-series Approach
Abstract INTRODUCTION: Because the antibody neutralizing respiratory syncytial virus (anti-RSV) has a short period of immunization and high cost, the identification of regions and months of highest occurrence of bronchiolitis is very important. METHODS: An Autoregressive Conditional Poisson model was constructed for count data and compared to the standard

14. Inpatient interventions that may preclude outpatient open pyeloplasty in infants
ABSTRACT Objective: In the majority of published series, children undergoing open pyeloplasty are admitted for at least one night. We hypothesized that it would be possible in the majority of infants to perform open pyeloplasty as an outpatient procedure. Materials and Methods: All patients who underwent open pyeloplasty by a single surgeon between 2008 an

15. Enhanced settling of mature fine tailings (MFT) by paramagnetic nanofluids based on nanoiron
ABSTRACT The extraction of bitumen from sand by utilizing hot water processes results in the production of a slurry waste which is stored in so called “tailings ponds”. Within these ponds, while fast settling sand particles segregate from the slurry in relatively short time, the fines fraction accumulates in the center of the pond and then settles, becom

16. Coarse particles and hospital admissions due to respiratory diseases in children. An ecological time series study
ABSTRACT BACKGROUND: Exposure to particulate matter (PM) is associated with hospitalizations due to respiratory diseases among children. DESIGN AND SETTING: An ecological time series study was carried out to identify the role of coarse fractions of particulate matter (PM10-2.5) in hospitalizations among children up to 10 years of age, in Piracicaba (SP)

17. IMPACT OF THE HYDRAULIC LOADING RATE ON THE HYDRODYNAMIC CHARACTERISTICS OF AN ANAEROBIC FIXED BED REACTOR TREATING CATTLE SLAUGHTERHOUSE WASTEWATER
ABSTRACT The hydrodynamic behavior of an anaerobic fixed bed reactor (AFBR) was evaluated in the treatment of cattle slaughterhouse wastewater. The AFBR was operated at hydraulic retention time (HRT) of 14, 11 and 8 h. Stimulus-response assays were carried out with Eosin Y and the experimental data were adjusted to the single-parameter theoretical models of

18. Use of a combined SVD-Kalman filter approach for induction motor broken rotor bars identification
Abstract This paper describes a new parametric spectral estimator for the identification of rotor bar fault of an induction motor by analyzing the stator current. This approach combines two methods: The first one, the Singular Value Decomposition method which allows the accurate detection and location of the fault's signature frequency. The second method all

19. SÍNTESE DE 2-(2-PIRIDIL)QUINOLINAS PROMOVIDA POR MICRO-ONDAS E SUAS ATIVIDADES ANTIFÚNGICAS
In this work a series of 2-(2- pyridyl)quinolines were prepared via a Povarov reaction between anilines, 2-pyridinocarbadehyde and ethyl vinyl ether under microwaves heating conditions. The optimized conditions herein reported allowed the preparation of several pyridylquinolines in yields in the range of 30-83%, some of them not previously accessible by this

20. Structural Analysis of the Double Bottom Structure During Ship Grounding by Finite Element Approach
Abstract Possibility of a water-transportation mode to experience numerous accidental loads is predicted limitless and always demand sustainable analysis. Impact phenomenon raises as main reason of environmental damage, for instance, grounding contributes in form of short-time impact and produces massive damage on the bottom structure of a marine vessels, e.

21. Suicide and meteorological factors in São Paulo, Brazil, 1996-2011: a time series analysis
Objective: Considering the scarcity of reports from intertropical latitudes and the Southern Hemisphere, we aimed to examine the association between meteorological factors and suicide in São Paulo. Method: Weekly suicide records stratified by sex were gathered. Weekly averages for minimum, mean, and maximum temperature (°C), insolation (hours), irradiati

22. Initial Surgical Experience with Aortic Valve Repair: Clinical and Echocardiographic Results
Abstract Introduction: Due to late complications associated with the use of conventional prosthetic heart valves, several centers have advocated aortic valve repair and/or valve sparing aortic root replacement for patients with aortic valve insufficiency, in order to enhance late survival and minimize adverse postoperative events. Methods: From March/2012

23. Uncracked joints in plain concrete pavements: causes, effects and possibilities of improvements
AbstractDuring the construction of Jointed Plain Concrete Pavements (JPCPs) in Chile, it was observed that joints remained uncracked. The objectives of this paper are to evaluate the effects of uncracked joints (UnCrJ) in JPCPs and to propose possible solutions or improvements to avoid or minimize this phenomenon. Considering low thermal amplitude as cause o

24. Transanal endoscopic operation for rectal cancer after neoadjuvant therapy
PURPOSE: In this paper we report the oncological outcomes from clinical series of patients with rectal cancer submitted to local excision after neoadjuvant therapy and discuss the indications for local excision in partial clinical responders. METHODS: We analysed a prospective database of 39 patients submitted to a transanal endoscopic operation for recta
