In the absence of clear clinical benefit, the cost of allografts and xenografts when compared to early generations of synthetics makes their selection in all but the most extreme cases difficult for the clinician. What these products have certainly done is create an opportunity for new synthetics to enter the market at a premium price. This will be an important field to watch in the coming years as long-term outcomes become known, and as efforts to control rising healthcare costs continue to drive the marketplace to safe, effective, and economical solutions in hernia repair.

Assumption 3 will be true in early generations, but becomes less accurate as the population converges. The impact of this assumption will be judged empirically. Given the selected antibody type, the mutated bit will either change from an incorrect value to a correct one or change from a correct to an incorrect value. Then for the offspring we have... 

Seed oil and protein are highly heritable traits in flax and can be selected for in early generations (see Oil Composition and Properties). Canadian flax breeders aim for 50% oil and 25% protein content on a dry matter basis. 

Redox flow batteries, under development since the early 1970s, are stUl of interest primarily for utility load leveling applications (77). Such a battery is shown schematically in Figure 5. Unlike other batteries, the active materials are not contained within the battery itself but are stored in separate tanks. The reactants each flow into a half-ceU separated one from the other by a selective membrane. An oxidation and reduction electrochemical reaction occurs in each half-ceU to generate current. Examples of this technology include the iron—chromium, Fe—Cr, battery (79) and the vanadium redox cell (80). 

Selective gas permeation has been known for generations, and the early use of p adium silver-alloy membranes achieved sporadic industrial use. Gas separation on a massive scale was used to separate from using porous (Knudsen flow) membranes. An upgrade of the membranes at Oak Ridge cost 1.5 billion. Polymeric membranes became economically viable about 1980, introducing the modern era of gas-separation membranes. Hg recoveiy was the first major apphcation, followed quickly by acid gas separation (CO9/CH4) and the production of No from air. 

Bent ansa-metallocenes of early transition metals (especially Ti, Zr, Hf) have attracted considerable interest due to their catalytic activity in the polymerization of a-olefins. Ruthenium-catalyzed olefin metathesis has been used to connect two Cp substituents coordinated to the same metal [120c, 121a] by RCM or to connect two bent metallocenes by cross metathesis [121b]. A remarkable influence of the catalyst on E/Z selectivity was described for the latter case while first-generation catalyst 9 yields a 1 1 mixture of E- and Z-dimer 127, -127 is the only product formed with 56d (Eq. 19).
