1. Shear Strength of a typical soil from Manaus, Brazil, stabilized with ceramic residue additive
ABSTRACT The purpose of this study is to determine the geotechnical behavior of a clayey surface soil typical to the Manaus region (Amazonas, Brazil), when mixed with ceramic powder from brick residue produced by potteries located in the county of Iranduba, Amazonas, Brazil, and with residual sand (the reference mixture), commonly used in pavements in the re

2. Comportamento mecânico de solo argiloso estabilizado com resíduo de vidro pulverizado em moinho de alta energia e de bolas
RESUMO A capital do Estado Amazonas apresenta dificuldades na construção de pavimentos devido à predominância superficial de argila em seu perfil geotécnico. Tal material mostra-se inadequado para a construção de subcamadas dessas estruturas urbanas. Avaliou-se, no presente estudo, o comportamento mecânico do solo argiloso típico de Manaus-AM na sua

3. Analysis of generation and characterization of construction and demolition waste on construction sites in the city of Recife, Brazil
ABSTRACT In order to planning the Construction and Demolition Waste (CDW) management approach on a construction site, it is necessary to have a prior knowledge of what is being generated (qualitative analysis), the quantity that is being generated (quantitative analysis), and what is the proper final destination assigned to this material. This article propos

4. Direct Numerical Simulation Code Validation for Compressible Shear Flows Using Linear Stability Theory
ABSTRACT: In order to simulate compressible shear flow stability and aeroacoustic problems, a numerical code must be able to capture how a baseflow behaves when submitted to small disturbances. If the disturbances are amplified, the flow is unstable. The linear stability theory (LST) provides a framework to obtain information about the growth rate in relatio

5. Effect of Web Holes and Bearing Stiffeners on Flexural-Shear Interaction Strength of Steel Cold-Formed C-Channel Sections
Abstract This paper presents an investigation on interaction equation between the required flexural strength, M, and the required shear strength, V, of cold-formed C-channels with web holes and bearing stiffeners. The primarily shear condition test was employed to study total 8 back to back lipped C channel sections of 95 and 100 mm depth when bearing stiffe

6. Aqueous dispersion of red clay-based ceramic powder with the addition of starch
The optimum dispersion and rheological properties of red clay-based ceramic suspension loaded with unary and binary starch were investigated in aqueous medium. The aqueous ceramic suspension was prepared consisting of red clay, quartz, feldspar, and distilled water. Using a polyelectrolyte dispersant (Darvan 821A), the ternary ceramic powder was initially op

7. In vitro evaluation of an alternative method to bond molar tubes
Despite the advances in bonding materials, many clinicians today still prefer to place bands on molar teeth. Molar bonding procedures need improvement to be widely accepted clinically. OBJECTIVE: The purpose of this study was to evaluate the shear bond strength when an additional adhesive layer was applied on the occlusal tooth/tube interface to provide rein

8. Estudo comparativo da estampabilidade da liga de aluminio AA1050 partindo de placas obtidas por vazamento direto e bobinas obtidas por vazamento contínuo. / Comparative study of the deep drawing alloy AA1050 from plates obtained by direct casting and coils obtained by continuos casting.
Stampability of aluminum alloys is a subject of interest to several industrial sectors because they are largely used in the fabrication of several parts and components. The choice is based upon the stampability and the relative manufacturing capability in relation to other aluminum alloys that contain larger amounts of alloying elements and, consequently, hi

9. Metologia para determinação de parâmetros para solos não saturados utilizando ensaios com umidade conhecida
In general the determination of constitutive parameters for unsaturated soils requires tests with controlled suction or allows measurement of suction. In this case it is highlighted the technique of axis translation, steam transfer or osmotic techniques. But generally most laboratories of soil mechanics do not have these tests and even when they are availabl

10. GCL shear strength evaluation - a new test method / Avaliação da resistência ao cisalhamento em GCLs - uma nova metodologia de ensaio
GCLs (Geosynthetic Clay Liners) are geosynthetic products used to compose flux control barriers in geotechnical and environmental works. The mechanical properties of GCLs have to be investigated in short and long term. Among its mechanical parameters, GCL internal shear strength plays an important role in the stability of slopes of geotechnical works. The ma

11. RESISTANCE OF INTERFACES SOILGEOSYNTHETICS: DEVELOPMENT OF EQUIPMENT AND TESTS / RESISTÊNCIA DE INTERFACES SOLO-GEOSSINTÉTICO: DESENVOLVIMENTO DE EQUIPAMENTO E ENSAIOS
The demand for better techniques of sizing motivated the development of studies capable to supply a larger understanding of the behavior of the geosynthetics when inserted in the soil mass. The interaction soil- geosynthetics it is complex, being function of the properties of the used materials, soil and geossintético, and expresses through the adhesion and
