A) Horizontal beds forming a transition from floodplain deposits to a palustro-lacustrine environment and lacustrine limestones. (B) Lacustrine deposits with stromatolitic bioherms (C) Palustrine limestone with abundant root traces. (D) Lacustrine bottom-set sediments enriched in organic matter and showing thin turbiditic layers. (E) Palustrine limestone with a well developed palaeosol at the top. (F) Various types of crushed shell fragments in a lacustrine mud. (G) Lacustrine bioclastic and oolitic sand deposited near a shore.

The root-finding method used up to this point was chosen to illustrate iterative solution, not as an efficient method of solving the problem at hand. Actually, a more efficient method of root finding has been known for centuries and can be traced back to Isaac Newton (1642-1727) (Eig. 1-2). 

Work on plasmas has roots extending back to the Greeks who found that amber mbbed with various materials tended to attract certain objects. The concept of plasma as the fourth state of matter can be traced to Sir William Crookes (2) in 1879. "So distinct are these phenomena from anything which occurs in air or gas at the ordinary tension, that we are led to assume that we are here brought face to face with Matter in a Fourth state or condition, a condition so far removed from the State of gas as a gas is from a Hquid." This description has been shown to be accurate over many years of experimentation and appHcation of plasmas. 

The name Theobroma cacao, food of the gods, indicating both the legendary origin and the nourishing quaUties of chocolate, was bestowed upon the cacao tree by Linnaeus in 1720. All cocoa and chocolate products are derived from the cocoa bean, the seed of the fmit of this tree. Davila Garibi, a contemporary Mexican scholar, has traced the derivation of the word from basic root words of the Mayan language to its adoption as chocolate in Spanish ( ) ... 

Figure 3 shows an optical profiler trace of the same portion of the wafer sample analyzed by the mechanical profiler. The resulting line scan in Figure 3a is similar to that for the mechanical system. The average and root-mean-square roughness are... 

As stated previously, traceability is fundamental to establishing and eliminating the root cause of nonconforming product and therefore it should be mandatory in view of the requirements for Corrective Action. Providing traceability can be an onerous task. Some applications require products to be traced back to the original ingot from which they were produced. In situations of safety or national security it is necessary to identify product in such a manner because if a product is used in a critical application and subsequently found defective, it may be necessary to track down all other products of the same batch and eliminate them before there is a disaster. It happens in product recall situations. It is also very important in the automobile and food industries in fact, any industry where human life may be at risk due to a defective product being in circulation. 

The roots of the LBNL can be traced back to the 1920s, and the pursuit of the secrets of the nucleus. Ernest O. Lawi ence, built the first large cyclotron (a particle accelerator) on the Berkeley campus of the University of California in 1931. Unlike most the other labs, LBNL s beginnings depended on the support of philanthropists who saw the promise in Lawrence s work. Seeking private sector support, an... 

Fig. 7.3 A representation of the (conjectured) ultrametric distribution of spin-glass equilibrium states. The leaves of the tree at bottom are identified with the states overlaps between states are measured by the number of levels it takes to trace the states back to their common roots . For the three states a, 0 and 7, for example, we have that qot y = q y = q and = 92 > 9l-...

Transfer of toxic chemicals among ecosystem compartments often occurs. For example, trace metals may be absorbed by plant roots or deposited onto the... 

The pharmacophore concept has now been widely accepted and used in the medicinal chemistry community as well as the field of computational molecular modeling. Two closely related definitions of pharmacophore have been employed by both the medicinal chemist and molecular modelers, and the root of this concept can be traced back to more than hundred years ago.
