Urban Structure and Suburban Selectivity [PDF]
Demography, 1964 Se informa respecto a los resultados de dos estudios sobre “selectividad suburbana.” El primero es un estudio longitudinal en su orientacon y examina la medida en que las grandes ciudades y sus suburbios estaban tendiendo a “polarizarse” alrededor de lineas de clase entre los anos 1940 y 1960. Nueve de las diez areas metropolitanas mayores exhibian una

Advanced Science, EarlyView.Herein, we propose a solar‐powered heavy metal trap (SPHT) for sludge disposal. The indoor experiments demonstrated that the sludge water content decreased from 90 % to 31 %, coupled with a decrease in heavy metal content to 6 % at most. Furthermore, the designed SPHT generated an initial potential of 0.10 V, and monitoring this hydrovoltaic potential ...

Variations in urban population structure [PDF]
Demography, 1964 Hasta ahara no se ha prestado atencion suficiente, en materia de investigacion, al estudio sistematico y cuantitativo de la persisiencia y las variaciones en el tiempo de las caracteristicas espaciales de la distribucion y composicion de la poblacion. Utilizando datos de distritos censales para 1940 y 1960 en dos ciudades (Seatle y Rochester), el autor

Hydrothermal Embedding of Pd Single Atoms Into SnO2 for Efficient CO Oxidation
Advanced Science, EarlyView.By applying hydrothermal regulation to SnO2‐supported PdO, we achieve atomic dispersion of Pd into the SnO2 lattice, which activates the lattice oxygen neighboring Pd atoms to generate oxygen vacancies and facilitates subsequent O2 activation, thereby promoting CO oxidation to proceed via a low‐energy‐barrier MvK pathway while avoiding CO poisoning ...

Structural Change in Urban Growth [PDF]
, 1995 The so-called industrial countries are by no means industrial any more. For the average age, employment in the industrial sector accounts for less than 40 percent of total employment in the OECD countries; in the United States it accounts for even less than 20 percent.

Metasurface‐Enabled Active‐Like Passive Radar
Advanced Science, EarlyView.A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Extra Climate Benefits From Afforestation Due to Reduced Forest Fragmentation in China
Advanced Science, EarlyView.Afforestation in China reduced forest fragmentation in 2015, transforming 51.8 M ha of edge forests into interior forests. This enhanced carbon sequestration (1.4±0.2 Pg CO2e, a cooling biogeochemical effect), while reduced albedo (−0.9 Pg CO2e, a warming biophysical effect) partially offset the gain, yielding a net extra climate benefit of ...
