Re-placement

The authors discussed the inherently safer design changes of 1996 which included re-placement of the atmospheric tank with a tank designed for 3.3 atm (50 psig). I qutne the authors conclusions on what their case study teaches ... 

P. cyclopium was cultivated emerged bv discontinuous re-placement of the nutrient solution (5 . At time indicated by arrows conidiospores were brushed off. All values are given per mg dry weight. Anthranilate adenylyl-transferase activity (AA (100 = 1.15 pkat) — Cyolo-peptine dehydrogenase activity (CD) (100 = 16 pkat) ... 

Proteins. In these much larger molecules, it is often possible to determine the phases by the method of isomorphous replacement. Most commonly. this means allowing ions of heavy atoms to diffuse into the solvent-filled vacancies in protein crystals, where they adopt well-defined positions. Thus, this represents the incorporation of atoms in completely new positions, rather than an atom-re-placement process. One exception is insulin, in which zinc ions are replaced by lead or mercury ions. Newer methods allow the structure to be solved by direct methods when excellent protein crystals are available. 

The various changes outlined can be contrasted with integration, wherein the emphasis is only on re-placement . 

Contemporary arrangements for integration in the UK include (and are probably still dominated by) the movement of individuals or re-placement However, there is now an increased awareness of the need for major structural change in orderto free up the resources to enable real inclusion. The result has been the introduction of a range of innovative and essentially experimental schemes wherein the skills and resources of the once-existing special school are delivered in the mainstream. Here, money follows children and there is no dilution of resource provision as children move from special school to mainstream school. The research reported in this book examines one of these projects. 

There are various applications for metal implants, including vascular and digestive stents, internal fracture treat-ments, face and dental surgery, and orthopedic joint re-placements. 

Another way this reaction is sometimes classified is based on the fact that a single type of anion (Cl ) has been exchanged between and Zn. That is, Cl is originally associated with in HCl and ends up associated with Zn in the product ZnCl2. We can call this a single-re-placement reaction in contrast to double-displacement reactions, in which two types of anions are exchanged. We can represent a single replacement as...
