Third Natures: Incubators of Public Space

Cristina Díaz Moreno and Efrén García Grinda , founders of the Madrid-based office AMID.cero9, shift the notion of the urban from the classic idea of the complete or ideal city, to one which engages with essential urban phenomena: the dynamics of confrontation, dispute and agreement between individuals, social groups and subcultures. In this way, public spaces are transformed from empty spaces into a real context for social interaction; and active involvement with social exchange becomes the main purpose of a project for a new architecture of the city.     

某金矿石矿物加工试验研究

为了给开发某金矿提供依据,在工艺矿物学研究的基础上,对该矿石进行了可选性试验研究。采用异戊基黄药+BK903G为选金捕收剂,完成了两粗、两扫、两精闭路流程试验。对于金品位为2.87 g/t的原矿,在磨矿细度为-0.074 mm占80%的情况下,可获得金品位51.94 g/t、金回收率为82.06%的金精矿。

Influence of immersion time and cationic latex nanoparticles concentration on flotation recovery

The influences of different concentrations of Polystyrene/Dodecyltrimethylammonium bromide latex nanoparticles and immersion times of mineral surfaces on flotation recovery have been investigated. Advancing water contact angle (θ_a) on the glass slides surfaces measured after conditioning them in different concentrations of diluted latex (0.028, 0.28, 0.56 g/L) at different immersion times (1, 10, 20, 30 min). Under these conditions, θ_a was changed between 29 and 105 degrees. The results showed that the concentrations of diluted latex as well as immersion time have important roles on the hydrophobic property of surfaces that covered with cationic latex nanoparticles.

The Initial, Boundary Value Problems for a Class of Generalized Diffusion Equations

The behavior for a class of initial, boundary value problems of generalized diffusion equations was studied utilizing the similarity transformation and shooting technique. Numerical solutions are presented for k(s)=s ^M, exponent M=1.0 to 5.0, and power law parameter N (N=0.3 to 3.0). The results shown that for each fixed M, the temperature distribution θ decreases with increasing in power law parameter N, and for each fixed N, the temperature distribution θ increases with the decreasing of M.
