Eh?Placer

ACM Transactions on Design Automation of Electronic Systems, 2016
The placement problem has become more complex and challenging due to a wide variety of complicated constraints imposed by modern process technologies. Some of the most challenging constraints and objectives were highlighted during the most recent ACM/IEEE International Symposium on Physical Design (ISPD) contests.

Placer Gold Deposits

2020
Placer gold deposits are abundant in Mongolia and form through endogenic and exogenic processes. Deposits are classified into four major genetic types: (1) eluvial-weathering zone, (2) deluvial, (3) proluvial, and (4) alluvial. The most economic deposits are often sourced from upper Cretaceous rocks and formed in late Cenozoic alluvial fans (Liskun and

Template-Based Placer

2016
This chapter covers the template-based placement approach proposed in the tool AIDA-L. In short, this Placer first extracts the topological relations described in a XML template file to a non-slicing B*-tree layout representation (Chang et al., Proceedings of the 37th ACM/IEEE Design Automation Conference (DAC), 2000, pp. 458–463). Then, the B*-tree is

Loparite in placers of the Lovozero placer cluster on the example of the Sergevan site

Геология рудных месторождений
Loparite is the main placer-forming mineral in placers located along the periphery of the Lovozero alkaline massif. The article presents new materials for the study of loparite from samples taken during field work at the Sergevan site of the Revda placer, located near the northern frame of the massif.

Primum Non Placere?

JAMA: The Journal of the American Medical Association, 1979
Defined in Butterworth's Medical Dictionary as "a pharmaceutically inactive substance administered as a drug either to satisfy a patient's desire for medication or in the course of a drug trial," the placebo (Latin, "I will please") is currently under attack ( Scientific American 231:17-23, 1974).

Inland Stream Placers

2020
A synthesis of data reveals that resource-base for yttrium was identified during 1970s in Chhottanagpur Granite Gneiss Complex (CGGC) terrain in Siri river and its tributary in Kunkuri area, central India. Consequent to demand for Y-rich mineral concentrates by IREL (India) Limited during 1980s, not only flow sheet was developed and a recovery plant ...

Placer Deposits of Mongolia

SEG Discovery, 1996
Editor’s note: Smimov uses the weathering definition of eluvial, meaning “an accumulation of rock debris produced*in-place by decomposition or disintegration of rock; a residue.” Two other terms in Smimov’s classification are not in common usage in North America nor in North American placer classification schemes By Russian definition, diluvium is an ...

Treatment of Placer Deposits

1991
Alluvial, or placer, gold has been washed away by flowing water or carried by blowing wind. It has then been deposited along with earth, sand, gravel, and other transported matter, especially on river beds. Although there is no way of knowing exactly how long ago humans felt enamored of the shiny yellow metal, there is reason to presume that gold ...

Gold Deposits—Placers

1987
Placer deposits provided early man with the first samples of gold and thereafter have accounted for a large production of the metal. If we include the Witwatersrand and other quartz-pebble conglomerates as fossil placers or modified placers, the placer type of auriferous deposit has provided more than two thirds of the world’s store of gold, about 80 ×
