The hybrid outcome of urban change: global city, polarized city?
Glocalism: Journal of Culture, Politics and Innovation, 2013 A wide range of studies supports the assumption that levels of socio-spatial polarization, segregation, and exclusion are rising in global cities over the past decades as a direct outcome of certain global processes, such as the deindustrialization ...

Inberitance patterns of tetraploid Dioscorea alata varieties [PDF]
, 2009 Polyploidy is a crucial issue for yam improvement programmes. Recent studies have revealed that the basic chromosome number of the species D. alata is x = 20 and that accessions with 2n = 40, 60 and 80 chromosomes are diploid, triploid and tetraploid ...

Continuous Avalanche Segregation of Granular Mixtures in Thin Rotating Drums
, 1999 We study segregation of granular mixtures in the continuous avalanche regime (for frequencies above ~ 1 rpm) in thin rotating drums using a continuum theory for surface flows of grains. The theory predicts profiles in agreement with experiments only when

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Take the money and run: Economic segregation in U.S. metropolitan areas [PDF]
Compared to racial segregation, economic segregation has received little attention in recent empirical literature. Yet a heated debate has arisen concerning Wilson's hypothesis (1987) that increasing economic segregation plays a role in the formation of ...

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Seeking borophene on Ni3Al(111): an experimental characterization of boron segregation and oxidation
JPhys MaterialsSynthesis of a stable, well ordered honeycomb borophene (hB) phase has been achieved to date by exploiting Al(111) as a growth substrate, which provides the necessary charge doping to compensate the high hexagonal-holes density.

Advanced Engineering Materials, EarlyView.This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

The Causal Impact of Segregation on a Disparity: A Gap-Closing Approach
Sociological ScienceSegregation—whether across schools, neighborhoods, or occupations—is regularly invoked as a cause of social and economic disparities. However, segregation is a complicated causal treatment: what do we mean when we appeal to a world in which segregation ...
