In contrast, the range of observed redox potentials in copper proteins is from +183 mV for halocyanin33 to +785 mV for the type-1 copper center in fungal laccase.34 Seven different types of copper sites have so far been characterized in copper proteins. They will be described below. 8.14...
Freeport-McMoRan is one of the largest diversified mining companies in the world. And the company’s large footprint in North and South America is particularly large when it comes to sustainable copper mining. The company has seven different copper mines in Arizona and New Mexico. Currently the ...
Therefore, to identify copper mining activity, we restrict our data to observations from Chile's copper mining regions, which encompass the northern seven regions. We assume that the majority of deaths occurring in these regions relate to workers in copper mines. These regions present no coal ...
The seven heavenly bodies known to the ancients were associated with the seven metals known in antiquity, and Venus was assigned to copper, both because of the connection to the goddess and because Venus was the brightest heavenly body after the Sun and Moon and so corresponded to the most lu...

This hood with its backsplash would be at home in any coastal design with a backsplash of blue and white tiles decorated with seven types of Ocean life. My wife Carolyn and I are very grateful your beautiful hood is now the center of attention when we entertain guests in our new kitchen ...
The seven PVAs of different DP-DS values prepared here are as follows: 180-100, 130-98, 130-91, 77-97, 77-92, 33-95, and 33-90. The DS was determined by the NMR method, within an error of± 1%. Beside these PVAs, commer- cially-available PVAs (Unitika, 250-98; Uni- ...
However, the bronzes from other states of the same period could be used as a reference for the comparison. There are seven states that were considered to be the most powerful in the Warring States period, including the Qi, Chu, Yan, Han, Zhao, Wei, and Qin states (Fig. 1) [1, 2]...
It results from the dysregulation of cellular iron homeostasis, which distinguishes itself from other types of cellular demise like autophagy, apoptosis, since it depends on iron and is activated by elastin and RAS selective lethal 3 by stimulating ras-ref-mek-erk signaling [82,83]. Strikingly, ...
Finally, the amount of primary copper (b) was estimated through backwards calculation from this final demand via manufacturing of semi-finished products and trade. Part of this primary copper comes from domestic mining (a). The remainder was assumed to be imported (Mcr, Xcr). The simple stock...
