In specific places

The elements that form ionic compounds are found in specific places in the periodic table. Atomic anions are restricted to elements on the right side of the table the halogens, oxygen and sulfur. All the elements in the s, d, and f blocks, on the other hand, form compounds containing atomic cations. 

The amino acid units that make up a protein molecule are joined together in a precise sequence when the protein is made on a ribosome. The chain is then folded, often into a very compact form. Sometimes the chain is then cut in specific places. Pieces may be discarded and parts may be added. A metal ion, a coenzyme derived from a vitamin, or even a single methyl group may be attached to form the biologically active protein. The final product is a complex and sophisticated machine, often with moving parts, that is exquisitely designed for its particular role. 

Restriction enzymes, which cut DNA in specific places, were... 

When microtubules were visualized by electron microscopy (EM), after the improvement of methods of fixation, it was realized that they formed the structural basis of flagellar axonemes and of so-called spindle fibers, as well as occurring as individual filaments in the cytoplasm. Their designation as part of the cytoskeleton suggested that they acted mainly as fixed structural supports. Subsequent research has focused more and more on their dynamic behavior and on their role as tracks for motor proteins, which may, for example, transport chromosomes during cell division. Microtubules are found in all eukaryotic cells and are essential for many cellular functions, such as motility, morphogenesis, intracellular transport, and cell division. It is that dynamic behavior that allows microtubules to fulfill all of these functions in specific places and at appropriate times in the cell cycle. 

In the focus groups, we made the somewhat paradoxical discovery that asking participants to ground their discussions of qualities associated with good writing in specific places allowed us to make connections between and among those stories to more general qualities, (see Chapter 2)... 

Figure 14.10 Optical scheme for a spectrophotometer with an echelle grating. For clarity only the central section of the beam issuing from source 1 is represented (this beam should cover the whole mirror 2). The echelle grating 5, separates the radiations arriving from the source in the horizontal plane (in x). The prism then deviates the radiation in the vertical plane (in y). The path of three different spectral lines is shown. The images of the entrance aperture 2 are in the focal plane 8. In the past, to detect these radiations, photomultiplier tubes (PMT) of reduced size were installed in specific places, but now charge transfer devices (charge coupled or charge injection devices, CCD/CID) are used, as an electronic equivalent of photographic plates. This allows a continuous spectral cover from 190 to 800 nm with excellent resolution. Sensors of 500 X 2000 pixels (each 12 x 12p,m) are now used.

Ninety-one of the 111 elements in the periodic table occur in nature. The remaining 20 elements are synthetic, which means they can only be made in a laboratory. All chemical elements are organized in a chart called the periodic table of the elements. In this table, the elements are located in specific places in a chart according to their properties and behaviors. The elements name and each elements symbol, which is usually made up of one or two letters, are listed. The one-letter symbol is always written with an uppercase letter, such as F for fluorine and N for nitrogen. When the element has a two-letter symbol, the first letter is uppercase and the second is lowercase, such as Al for aluminum and Si for silicon. In the periodic table in the appendix, note where the metals are located their squares are light purple. 

The key concept is that of differentiation this is the process by which the whole genome in each cell is selectively switched off or silenced in specific places on the chromosomal DNA, leaving only a subset of all possible genes available to be translated into proteins. It is the characteristics of the proteins in the set of all proteins in a cell, and their relative amounts, that are the fundamental determinants of the final nature of a cell, and hence what tissue name we might assign to it. 

Unidirectional tapes consisting of flat bundles of filaments already impregnated with catalysed resin can be used to increase stiffness and strength in specific places, and whole parts can be made from tape, applied under computer control. 

The resonance faults occurred in specific places of the network where the concentrate parameters of capacitance and inductance are tuning at resonance frequency and not precisely the weak point of the system. 

In Portugal, too, there would be adopted a system based on green point . Raw materials producers and developers are responsible for utilization of the packaging wastes fraction content in solid city-wastes. Commercial and industrial packaging distributors and users are responsible for utilization of these products, which must be done in specific places, with cautional money systems, or with an integrated system. 

It is quite clear that although the interests of the country and those of CIMPOR are identical in this matter, the desired result will only be accomplished if the state takes part, through the Central Administration, or Autarchys, regarding the concentration of the tyres in specific places. 

However, it is important to note that improvements in road design may inadvertently result in older drivers driving more often than otherwise, thereby increasing their exposure within the road system in specific places and times. If these places and times were associated with an increased crash risk for reasons other than roadway design (e.g., because of increased traffic density), the crash risk for older drivers would similarly increase. This would then be considered a form of negative behavioural adaptation. 

Gestures may be particularly important when speakers use English verbs like do, put and get in instructional contexts. As McNeill and Duncan (2000) demonstrate, these verbs lack the details of manner and motion that can be supplied by adverbial phrases. In the context of Libby s instruction, verbs like put and set provide very little information about the manner and motion of her actions. They do not tell, for example, how the steel rises, how the bolt spins, how long the process lasts, or how quickly Libby can finish the task. Yet these details help us understand the process as a dynamic set of actions that take place at specific times and in specific places.
