1. Qual o sistema adesivo deve ser utilizado durante a técnica de dentina úmida?
Durante a utilização da técnica de adesão à dentina úmida os sistemas adesivos mais recomendados são os que contêm em sua composição os solventes álcool ou acetona
. A razão do melhor desempenho desse tipo de solvente em dentina úmida é que, após a desmineralização e exposição das fibras de colágeno, estas se mantêm expandidas

2. Native and ornamental exotic resources in pollen loads and garbage pellets of four stingless bees (Apidae, Meliponini) in an urban environment with riparian native forest
Abstract: An entomopalynological study to assess pollen use by wild bees was performed in an urban environment with riparian native forest in the Chaco region of Argentina. A combined method for sampling pollen loads and garbage pellets at nest entrances in four stingless bees with different entrance size and forager traffic was here successfully used. Samp

3. GROUPNESS RACIAL E FLUTUAÇÕES ATITUDINAIS DE PARDOS ENTRE FRONTEIRAS SIMBÓLICAS E SOCIAIS
Neste artigo, examinamos a permeabilidade das fronteiras simbólicas raciais a partir da identificação e análise de atitudes referentes: (1) ao preconceito; (2) à mistura racial e (3) ao apoio às políticas de cotas. Mais especificamente, exploramos a hipótese de que as opiniões posicionais dos pardos, em virtude da sua localização intermediária no

4. Effect of Boundary Layer and Rotor Speed on Broadband Noise from Wind Turbines
ABSTRACT: Trailing edge surface of aerofoil is an important source of broadband aerodynamic noise production. In this paper, three aerofoil self-noise mechanisms from turbulent boundary layer near trailing edge surface are studied. Numerical computations were performed for a three bladed 2 MW horizontal axis upwind turbine of blade length 37 m and source hei

5. Selective Solar Surface Solar Based on Black Chromium: Influence of Electrodeposition Parameters in the Absorption of Surfaces
The search for the reduction of costs for the implementation of renewable energies implies in the optimization of the parameters of the manufacturing processes of consolidated technologies. Among these technologies are the solar collectors composed of absorber films characterized by high absorption in the spectrum range corresponding to solar radiation and l

6. Impact of a provider training program on the treatment of children with autism spectrum disorder at psychosocial care units in Brazil
Objective: To develop, implement, and verify the impact of a training program for health care providers working with children with autism spectrum disorder (ASD) in psychosocial care centers for children and adolescents (Centro de Atenção Psicossocial à Infância e à Adolescência – CAPSi) in São Paulo, Brazil. Methods: This quasi-experimental study

7. FORM OF LAYING HENS EGGS IN THE FUNCTION OF DIFFERENT LAMPS USED IN PRODUCTION
ABSTRACT: Lighting, either in its intensity or in its luminous spectrum, affects the eggs quality. This study evaluated the effect of four lamps (sodium vapor lamp, mercury vapor lamp, fluorescent lamp and incandescent lamp) that have different luminous spectra in the form of commercial poultry eggs. For this, 60 laying hens of the same age were separated fo

8. Classification of Flying Insects with high performance using improved DTW algorithm based on hidden Markov model
ABSTRACT Insects play significant role in the human life. And insects pollinate major food crops consumed in the world. Insect pests consume and destroy major crops in the world. Hence to have control over the disease and pests, researches are going on in the area of entomology using chemical, biological and mechanical approaches. The data relevant to the fl

9. Nidificação de abelhas e vespas solitárias e biologia reprodutiva de Megachile dentipes Vachal (Hymenoptera, Megachilidae) em ninhos-armadilha
Terrestrial ecosystems, solitary bees and wasps play important roles as pollinators, predators and parasites. Most part of the life of these Hymenoptera is designed to aspects related to nesting, including the search of the nest site, nest construction and food collection to rear the larvae. However, in natural environments the nests of these insects are dif

10. Vibroacustografia na avaliação tridimensional de artroplastia total de quadril / Vibro-acoustography in the tridimensional evaluation of total hip arthroplasty
Vibro-acoustography (VA) is a high lateral resolution (<0.7 mm), speckle-free, non- ionizing and non-invasive image based on the nonlinear combination phenomenon of ultrasound waves (MHz) that generates a narrow focus region of low frequency (kHz). In this work, we propose a VA-based tridimensional evaluation of the exposed area of implants, after total hip

11. Spread of phosphine resistance among brazilian populations of three species of stored product insects
The resistance to fumigant insecticides in stored-products insects is often recorded. Several factors influence the evolution of insecticide resistance. Among these, the frequency of applications and the migration of resistant populations are of primary importance for the stored-product insects. The aim of this study was to characterize the spectrum and inve

12. Enumeração de espectro de distâncias de esquemas de modulação codificada em treliça empregando codificação turbo
In this work, a performance analysis of transmission schemes employing turbo trellis coded modulation. In general, the performance analysis of such schemes is guided by evaluating the error probability of these schemes. The exact evaluation of this probability is very complex and inefficient from the computational point of view, a widely used alternative is
