SYDNEY (Reuters) -PwC Australia on Sunday entered an exclusivity agreement with private equity firm Allegro Funds to sell its government practice for A$1 as it brought in an executive from Singapore to lead its local firm through the fallout from a national scandal. The scandal, which...
Note that the applied Solder Mask Expansion Rule will be applied from the pad/via hole perimeter rather than its land pattern perimeter, so an existing rule may lead to unexpected results. To cater for the above, an additional Solder Mask Expansion rule can be created using the query expressio...
MrBayes was run for 1 million generations with sample frequency 1000, 3 runs with 4 chains each, and the majority rule consensus tree was calculated after a 50% burnin. For characters and matrix, see Additional file 1. The matrix is also deposited in the Dryad data repository (http://...
This plant would recycle not only metal such as steel lead and copper but also paper and rubber as well. Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete the rubbish will be treated like this: First it ...

Resulting instability of the ACL-deficient knee may lead to significant functional impairment and osteoarthritis [2]. Reconstructive surgery, which is usually performed using a tendinous autograft after entire resection of the ACL remnants [3], has become the advocated treatment of ACL injuries in ...
and ethnohistorical records (e.g., Hantman1990;1993; Kavanaugh 1982; Mouer1983; Rountree1993). By the 16th century, a circum-Chesapeake exchange sphere that conveyed locally produced shell beads and copper objects from beyond the region is apparent archaeologically (Klein and Sanford2004, pp. ...
2.1. Synthesis and Characterization of the Ligands and Their Respective Complexes Ligands L1 and L2 were prepared via the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction between the respective organohalide with 2-ethynyl pyridine and sodium azide in a water–methanol (2:1) mixture under...
Generally, suspensions of NPs that have a zeta potential value under –25 and over +25 mV are stable, due to the electrostatic repulsion between strongly charged surfaces. The repulsion between lower-charged NPs is weak, therefore the van der Waals attraction forces can lead to particle ...
