Many cities in the Global South are structurally different from Northern, particularly American, on which much of urban sociology’s conceptual apparatus has been based. Thus, depicting them terms a standard vocabulary risks imposing an inappropriate way seeing. We need that is able to accommodate their experience. This special issue contributes work building vocabulary. select five keywords soc...

reinforced concrete (rc) slabs exhibit complexities in their structural behavior under load due to the composite nature of the material and the multitude and variety of factors that affect such behavior. current methods for determining the load-deflection behavior of reinforced concrete slabs are limited in scope and are mostly dependable on the results of experimental tests. in this study, an ...

in this paper, a systematic study on the effects of particle size and hybrid of two different size of silica nanoparticles on the toughening mechanisms of bisphenol-a epoxy was conducted. nanosilica particles with mean diameter of 17 nm and 65 nm were blended into epoxy system. probable synergy effects of these two nanoparticles on young’s modulus and yield strength have been investigated. resu...

objective: the aim of this study was to measure and compare the transverse strength and deflection of two acrylic resins. method and materials: a total of 30 samples, with dimensions of 2.5×10×65mm, were prepared with acropars and meliodent acrylic resins according to ada specification no. 12. the specimens were divided into two groups of 15 samples each. a three-point bending test was carried ...

BACKGROUND AND PURPOSE Introduction of an instrument into the working channel of ureteroscopes adversely affects flow and deflection. We evaluated the alterations in ureteroscope channel flow and deflection caused by available Nitinol(R) baskets. MATERIALS AND METHODS We compared the effects of 11 Nitinol baskets on irrigation flow and deflection of three flexible ureteroscopes (Olympus P3, A...

In this paper, we present a label-based approach for implementing deflection in a photonic packet network, and we introduce an algorithm for determining deflection options in a manner which eliminates looping. A general analytical model is developed to evaluate packet loss probabilities in networks with deflection. The analysis may be applied to a wide class of deflection schemes and may be app...

Thin-walled workpieces, such as aero-engine blisks and casings, are usually made of hard-to-cut materials. The wall thickness is very small and it is easy to deflect during milling process under dynamic cutting forces, leading to inaccurate workpiece dimensions and poor surface integrity. To understand the workpiece deflection behavior in a machining process, a new real-time nonintrusive method...

A promising option to raising busty interchange in system communication could be Optical Burst Switched (OBS) networks among scalable and support routing effective. The routing schemes with disputation resolution got much interest, because the OBS network is buffer less in character. Because the deflection steering can use limited optical buffering or actually no buffering thus the choice or de...

The mechanical strength of silicon wafers 100 μm thickness was studied. Loading the carried out by "ring-on ring" method, stress and deflection under small ring were determined finite element modeling. validity calculation model checked comparing dependences on load obtained in experiment simulation. effect methods obtaining their surface treatment strength, as well connection...
